Late Holocene human-induced modifications to a central Polynesian island ecosystem.

A 7000-year-long sequence of environmental change during the Holocene has been reconstructed for a central Pacific island (Mangaia, Cook Islands). The research design used geomorphological and palynological methods to reconstruct vegetation history, fire regime, and erosion and depositional rates, whereas archaeological methods were used to determine prehistoric Polynesian land use and resource exploitation. Certain mid-Holocene environmental changes are putatively linked with natural phenomena such as eustatic sea-level rise and periodic El Niño-Southern Oscillation events. However, the most significant changes were initiated between 2500 and 1800 years and were directly or indirectly associated with colonization by seafaring Polynesian peoples. These human-induced effects included major forest clearance, increased erosion of volcanic hillsides and alluvial deposition in valley bottoms, significant increases in charcoal influx, extinctions of endemic terrestrial species, and the introduction of exotic species.

Interisland and interarchipelago transfer of stone tools in prehistoric Polynesia.

Tracing interisland and interarchipelago movements of people and artifacts in prehistoric Polynesia has posed a challenge to archaeologists due to the lack of pottery and obsidian, two materials most readily used in studies of prehistoric trade or exchange. Here we report the application of nondestructive energy-dispersive x-ray fluorescence (EDXRF) analysis to the sourcing of Polynesian artifacts made from basalt, one of the most ubiquitous materials in Polynesian archaeological sites. We have compared excavated and surface-collected basalt adzes and adze flakes from two sites in Samoa (site AS-13-1) and the Cook Islands (site MAN-44), with source basalts from known prehistoric quarries in these archipelagoes. In both cases, we are able to demonstrate the importing of basalt adzes from Tutuila Island, a distance of 100 km to Ofu Island, and of 1600 km to Mangaia Island. These findings are of considerable significance for Polynesian prehistory, as they demonstrate the movement of objects not only between islands in the same group (where communities were culturally and linguistically related) but also between distant island groups. Further applications of EDXRF analysis should greatly aid archaeologists in their efforts to reconstruct ancient trade and exchange networks, not only in Polynesia but also in other regions where basalt was a major material for artifact production.

Women Of India: Developmental setbacks of gender inequity

This project examines rural Indian women and discusses the strong correlation between gender inequity and the setbacks that have crippled development. The embedded caste system has created a distinct social hierarchy, which has incidentally deprived women of their freedom and voice. Gender inequity and social stratification are direct causes of the AIDS epidemic, research revealing a contingency between lack of empowerment and exposure to the disease. Additionally, the HIV/AIDS virus carries a strong cultural stigma, which influences whether or not women will seek treatment if infected, since AIDS victims face extreme social isolation and discrimination, in India. This project discusses several cause-and-effect frameworks related to gender inequity, which have stunted the growth and success of India.

Violencia estructural: una ilustración del concepto

El término violencia estructural es aplicable en aquellas situaciones en las que se produce un daño en la satisfacción de las necesidades humanas básicas (supervivencia, bienestar, identidad o libertad) como resultado de los procesos de estratificación social, es decir, sin necesidad de formas de violencia directa. El término violencia estructural remite a la existencia de un conflicto entre dos o más grupos de una sociedad (normalmente caracterizados en términos de género, etnia, clase, nacionalidad, edad u otros) en el que el reparto, acceso o posibilidad de uso de los recursos es resuelto sistemáticamente a favor de alguna de las partes y en perjuicio de las demás, debido a los mecanismos de estratificación social. La utilidad del término violencia estructural radica en el reconocimiento de la existencia de conflicto en el uso de los recursos materiales y sociales y, como tal, es útil para entender y relacionarlo con manifestaciones de violencia directa (cuando alguno de los grupos quiere cambiar o reforzar su posición en la situación conflictiva por la vía de la fuerza) o de violencia cultural (legitimizaciones de las otras dos formas de violencia, como, por ejemplo, el racismo, sexismo, clasismo o eurocentrismo).

La molécula conductual de relaciones públicas en la comunicación gubernamental con los inmigrantes en España

La afluencia creciente de inmigrantes en España conforma una nueva estratificación social. De todos los actores que intervienen en este proceso migratorio y la integración de los acogidos, el Gobierno Central español tiene una responsabilidad legal, pero también comunicacional. De ahí que se plantee el análisis de cómo se diseña y se elaboran tres herramientas oficiales del Ministerio de Trabajo e Inmigración desde la disciplina de las relaciones públicas y, en concreto, desde las relaciones con los inmigrantes considerados públicos minoritarios. La conducta de comunicación del Gobierno que este trabajo evidencia deja entrever una estrategia de relaciones públicas poco definida.

Skill formation in Britain and Germany: Recent developments in the context of traditional differences. CES Germany & Europe Working Papers, No.06.1, 2006

This paper proposes a comparison of skill formation in Germany and Britain over the last decades. Taking historical trends into account, the two cases can be regarded as representing different types of skill production regimes. Institu-tional features include a relatively low degree of standardization of training and a larger amount of on-the-job training in Britain. In Germany, post-compulsory training has been conducted predominantly within the dual system of vocational training, underlining the vocational specificity of a large part of the labor market. As a consequence, international differences in individual skill investments, transitions from school to work and other life-course patterns can be observed. At least in Britain, however, the situation seems to have changed considerably during the 1990s. The paper argues that the divergence in more recent developments can still be understood as an expression of historical path-dependency given the traditional connections between the post-compulsory training system and the broader societal context in which it is embedded. These concern, in particular, links with the system of general and academic education as the basis for – and also a possible competitor with – vocational training; links with the labor market as they are indicated by specific skill requirements and returns to qualifications; and, links with the order of social stratification in the form of the selective acquisition and the social consequences of these qualifications. The links manifest themselves as typical individual-level consequences and decisions. Founded on the basis of these distinctions, the aim of this paper is to investigate the preceding conditions for recent developments in the qualification systems of Britain and Germany, which have adapted to specific challenges during the last decades.
