NUEVOS ESPACIOS URBANOS CONSTRUIDOS EN COSTA RICA: DE LA VALORACIÓN AL IMPUESTO TERRITORIAL

Este artículo presenta la relación entre las nuevas construcciones de vivienda, y edificios en general y su efecto en la valoración de la propiedad inmuebles y la valorización de los espacios urbanos.  Primero se discuten las licencias de construcción y las formas de valorización, incluyendo además la normatividad de las licencias de construcción en Costa Rica.  Estos procesos de valorización individual y colectiva de los espacios urbanos, están directamente relacionados con el impuesto territorial aplicado en Costa Rica.  Se incluyen las modalidades que la ley tiene para modificar el valor de la propiedad inmueble. 

Movimiento Social Alianza Territorial Mapuche Pu Lof Xawun

Desde la Conquista, el pueblo mapuche ha enfrentado despojos y diversos pactos para mediar la relación con la nación chilena. El gobierno de Augusto Pinochet se aseguró la adopción de políticas económicas neoliberales, estimulando a las forestales, principalmente, su instalación en la octava y novena región del país y hacer uso de las tierras mapuche para la mega industrialización. Ello representó un nuevo despojo a la población mapuche de sus territorios y su confinamiento a reducciones. Es necesario explicar las leyes reformuladas y promulgadas por los gobiernos chilenos, como la Ley de Seguridad Interior del Estado y la Ley Antiterrorista, herramientas heredadas que la democracia de Lagos y Bachelet dieron al tratamiento al conflicto actual.

Relationships between employees and their nomadic, non-territorial work environment

Recent and current socio-cultural trends are significant factors impacting on how business is conduced and correspondingly, on how work environments are designed. New communication technology is helping to break physical boundaries and change the way and speed of conducting business. One of the main characteristics of these new workplaces is non-permanency wherein the individual employee has no dedicated personally assigned office, work station, or desk. In this non-territorial, nomadic situation, employees undertake their work tasks in a wide variety of work settings inside and outside the office building. Such environments are understood to be must suitable where there is the need for high interaction with others as well as a high level of concentrated, independent work. This thesis reports on a project designed to develop a deeper understanding of the relationships between people (P) and their built environment (E) in the context of everyday work practice in a nomadic and non-territorial work environment. To achieve this, the study focuses on the experiences of employees as they understand them in relation to their work and the designed/ physical work environment. In this sense, the study is qualitative and grounded in nature. It does not assume any previously established theory nor test any presenting hypothesis. Instead it interviews the participants about their situations at work in their workplace, interprets natural interaction and creates a foundation for the development of theory informing workplace design, particularly theory that recognises the human nature of work and the need, as highlighted by several seminal researchers, for a greater understanding of how people manage and adapt in dynamic work environments.

Territorial strategies and regions

The notion of territorial strategy emerged in the 1990s and has become more and more popular since. It refers to that combination of factors purposely assembled by governments, private and public companies, universities, and industrial associations to exploit a specific geographic competitive advantage in order to boost economic growth through the development of entrepreneurial activity and innovation. Three factors are generally considered to be the building blocks of a territorial strategy: natural resources, human capital, and industrial capabilities. Natural resources derive from environ­ mental conditions and represent raw materials or land available in a region. The presence of natural resources characterizes the typology of an industry (related to tourism, oil, wood, fish, and so forth) that exists or could exist in a certain area. Human capital refers to the stock of competences available in a certain region resulting from education and work experience. Industrial capabilities relate to complex constructs of specialized expertise, the confidence to apply knowledge and skills in various contexts and under changing conditions, and an ability repeatedly to improve methods and processes in a specific industry.

Sustaining productivity of a Vertosol at Warra, Queensland, with fertilisers, no-tillage or legumes. 8. Effect of duration of lucerne ley on soil nitrogen and water, wheat yield and protein.

Soil nitrogen (N) supply in the Vertosols of southern Queensland, Australia has steadily declined as a result of long-term cereal cropping without N fertiliser application or rotations with legumes. Nitrogen-fixing legumes such as lucerne may enhance soil N supply and therefore could be used in lucerne-wheat rotations. However, lucerne leys in this subtropical environment can create a soil moisture deficit, which may persist for a number of seasons. Therefore, we evaluated the effect of varying the duration of a lucerne ley (for up to 4 years) on soil N increase, N supply to wheat, soil water changes, wheat yields and wheat protein on a fertility-depleted Vertosol in a field experiment between 1989 and 1996 at Warra (26degrees 47'S, 150degrees53'E), southern Queensland. The experiment consisted of a wheat-wheat rotation, and 8 treatments of lucerne leys starting in 1989 (phase 1) or 1990 (phase 2) for 1,2,3 or 4 years duration, followed by wheat cropping. Lucerne DM yield and N yield increased with increasing duration of lucerne leys. Soil N increased over time following 2 years of lucerne but there was no further significant increase after 3 or 4 years of lucerne ley. Soil nitrate concentrations increased significantly with all lucerne leys and moved progressively downward in the soil profile from 1992 to 1995. Soil water, especially at 0.9-1.2 m depth, remained significantly lower for the next 3 years after the termination of the 4 year lucerne ley than under continuous wheat. No significant increase in wheat yields was observed from 1992 to 1995, irrespective of the lucerne ley. However, wheat grain protein concentrations were significantly higher under lucerne-wheat than under wheat wheat rotations for 3-5 years. The lucerne yield and soil water and nitrate-N concentrations were satisfactorily simulated with the APSIM model. Although significant N accretion occurred in the soil following lucerne leys, in drier seasons, recharge of the drier soil profile following long duration lucerne occurred after 3 years. Consequently, 3- and 4-year lucerne-wheat rotations resulted in more variable wheat yields than wheat-wheat rotations in this region. The remaining challenge in using lucerne-wheat rotations is balancing the N accretion benefits with plant-available water deficits, which are most likely to occur in the highly variable rainfall conditions of this region.

Poor adoption of ley-pastures in south-west Queensland: biophysical, economic and social constraints.

The present review identifies various constraints relating to poor adoption of ley-pastures in south-west Queensland, and suggests changes in research, development and extension efforts for improved adoption. The constraints include biophysical, economic and social constraints. In terms of biophysical constraints, first, shallower soil profiles with subsoil constraints (salt and sodicity), unpredictable rainfall, drier conditions with higher soil temperature and evaporative demand in summer, and frost and subzero temperature in winter, frequently result in a failure of established, or establishing, pastures. Second, there are limited options for legumes in a ley-pasture, with the legumes currently being mostly winter-active legumes such as lucerne and medics. Winter-active legumes are ineffective in improving soil conditions in a region with summer-dominant rainfall. Third, most grain growers are reluctant to include grasses in their ley-pasture mix, which can be uneconomical for various reasons, including nitrogen immobilisation, carryover of cereal diseases and depressed yields of the following cereal crops. Fourth, a severe depletion of soil water following perennial ley-pastures (grass + legumes or lucerne) can reduce the yields of subsequent crops for several seasons, and the practice of longer fallows to increase soil water storage may be uneconomical and damaging to the environment. Economic assessments of integrating medium- to long-term ley-pastures into cropping regions are generally less attractive because of reduced capital flow, increased capital investment, economic loss associated with establishment and termination phases of ley-pastures, and lost opportunities for cropping in a favourable season. Income from livestock on ley-pastures and soil productivity gains to subsequent crops in rotation may not be comparable to cropping when grain prices are high. However, the economic benefits of ley-pastures may be underestimated, because of unaccounted environmental benefits such as enhanced water use, and reduced soil erosion from summer-dominant rainfall, and therefore, this requires further investigation. In terms of social constraints, the risk of poor and unreliable establishment and persistence, uncertainties in economic and environmental benefits, the complicated process of changing from crop to ley-pastures and vice versa, and the additional labour and management requirements of livestock, present growers socially unattractive and complex decision-making processes for considering adoption of an existing medium- to long-term ley-pasture technology. It is essential that research, development and extension efforts should consider that new ley-pasture options, such as incorporation of a short-term summer forage legume, need to be less risky in establishment, productive in a region with prevailing biophysical constraints, economically viable, less complex and highly flexible in the change-over processes, and socially attractive to growers for adoption in south-west Queensland.

Struggles over resources and representations in territorial conflicts in the Northern Autonomous Atlantic Region (RAAN), Nicaragua

Territoriality is a central issue in indigenous peoples struggles. The territorial struggles involve struggles over the control of natural resources and over political participation and representation, but also over the perception of territorial rights and the symbolic representation of the territory. These struggles are carried through both in material and symbolic ways through recurring to different discourses and representations that provide legitimation for the territorial claims of the group. The study is located in the Northern Autonomous Atlantic Region of Nicaragua. The study concerns the territorial strategies, conceptions and practices of the indigenous people and other actors. Territorial conflicts exist between the autonomous region and the central government of Nicaragua, between mestizo settlers and indigenous people, between different indigenous groups, and between these and development agents such as conservation projects. The study focuses on how territorial discourses and representations are used to legitimate territorial control. Environmental, historical and cartographical discourses are the most important discourses recurred to. The influence of discourses and representations on the territorial practices and policies of the different actors, the links between the local struggles and global processes, and the broader structural factors impacting on the territorial struggles are also analysed. Among the structural factors are the problems related to land tenure and management and the use of natural resources, the advance of the agricultural frontier, the institutional weaknesses of the central and regional governments and the legislative processes. The territorial discourses are both recurred to in a strategic way and also grounded in local ideals and practices. The discourses have produced real effects for example in legislation, land tenure systems, political representation and environmental practices. Although the use of discourses and representations are an important power tool in territorial struggles, territorial control cannot be effectively accomplished merely through representing territorial claims in a legitimate way or through reforming legislation, as the conflicts are also largely a result of structural factors affecting the region. The fieldwork was carried out during a total of twelve months between 2000 and 2002. The research methods used were semi-structured interviews, participant observation and participatory research methods. A broad range of literary sources were also used to collect data. The study is located within the field of critical political geography with a discursive political ecology approach. It can be called a critical realist approach to the discursive analysis of indigenous territoriality.

Algunas reflexiones a partir de la Ley de Muerte Digna

El Senado Nacional sancionó recientemente una ley llamada “Ley de Muerte Digna”, la cual nos invita a hacer algunas reflexiones. La primera es llamar la atención justamente sobre el hecho de que la ley no trata de la muerte (como lo hace la Ley Nº 24.193 sobre trasplantes de órganos que deja estipulado, entre otras cosas, cómo se debe constatar la muerte), sino de la vida de las personas cuya salud se encuentra seriamente comprometida y que en muchos casos, no siempre, se presupone que se encuentra próxima a la muerte.

Ley natural, diálogo social y convicciones creyentes

Resumen: El artículo plantea una lectura transversal del Documento de la Comisión Teológica Internacional, titulado “En busca de una ética universal: una nueva mirada sobre la ley natural” de tal manera que, a partir del reconocimiento de una ley natural que subyace a toda norma, se procura mostrar cómo esa convicción no impide la participación de los cristianos en el diálogo social. El autor señala las paradojas a las que conduce la ética de la discusión y el lugar de la discusión pública como estímulo para alcanzar la verdad. Enfatiza la importancia del amor a la verdad como condición necesaria para que una sociedad sea noble y respetable. Considera el lugar del diálogo y el consenso y la existencia de una verdad última que la inteligencia puede captar en el marco de un sano pluralismo. También aborda la relación entre este pluralismo y las religiones y su contribución al debate público.

La Ley Saénz Peña, una cuestión de familia

En el presente año se ha cumplido el centenario de la ley más célebre en materia de emisión del voto, es decir, la llamada Ley Sáenz Peña. Y este aniversario encuentra al voto, un aspecto clave de la vida institucional, en el centro mismo del debate, tanto en la Argentina como en gran parte del mundo. Por cuestiones tecnológicas, como el llamado voto electrónico, como acto jurídico, al discutirse su naturaleza imperativa, como hecho sociológico, vista la creciente reticencia de gran parte de la sociedad a participar de los actos electorales, y encontrar su representatividad en las llamadas “redes sociales”, por la aparición del denominado referéndum revocatorio, que en cierta medida implica poner en duda la eficacia del voto, y el demagógico proyecto de bajar a 16 años la edad hábil del sufragante, el mismo es hoy objeto de análisis, revisión y enfoques renovadores.
