Regime shifts, defined as a radical and persistent reconfiguration of an ecosystem following a disturbance, have been acknowledged by scientists as a very important aspect of the dynamic of ecosystems. However, their consideration in land management planning remains marginal and limited to specific processes and systems. Current research focuses on mathematical modeling and statistical analysis of spatio-temporal data for specific environmental variables. These methods do not fulfill the needs of land managers, who are confronted with a multitude of processes and pressure types and require clear and simple strategies to prevent regime shift or to increase the resilience of their environment. The EU-FP7 CASCADE project is looking at regime shifts of dryland ecosystems in southern Europe and specifically focuses on rangeland and forest systems which are prone to various land degradation threats. One of the aims of the project is to evaluate the impact of different management practices on the dynamic of the environment in a participatory manner, including a multi-stakeholder evaluation of the state of the environment and of the management potential. To achieve this objective we have organized several stakeholder meetings and we have compiled a review of management practices using the WOCAT methodology, which enables merging scientific and land users knowledge. We highlight here the main challenges we have encountered in applying the notion of regime shift to real world socio-ecological systems and in translating related concepts such as tipping points, stable states, hysteresis and resilience to land managers, using concrete examples from CASCADE study sites. Secondly, we explore the advantages of including land users’ knowledge in the scientific understanding of regime shifts. Moreover, we discuss useful alternative concepts and lessons learnt that will allow us to build a participatory method for the assessment of resilient management practices in specific socio-ecological systems and to foster adaptive dryland management.

Errors in healthcare are commonplace and have significant impact on mortality, morbidity, and costs. Other high-risk industries are credited with strong safety records. These successes are due in part to a strong, committed organizational culture and their leadership. A consistent pattern of effective leadership behaviors; creating change, establishing a vision and strategic actions, and enabling and inspiring the organization's members to act, is present in these high-risk industries. This research examined the relationship between leadership practices and a medication safety regime. The hypothesis is strong leadership practices have a positive relationship with the degree of sophistication of a medication safety program (safety performance). Leadership was used as a surrogate for organizational culture and was measured in this research through the Kouzes and Posner's Leadership Practices Inventory. The Institute of Medicine's 14 Selected Strategies to Improve Medication Safety was used to measure the development of a medication safety regime. Leadership practices towards safety were assessed by surveying 2,478 critical care Registered Nurses in the greater Houston area. A response rate of 19% was achieved. Thirteen hospitals participated in the medication safety regime assessment. Data from 386 RN respondents from 53 institutions provided an overall description of unit (ICU) and organization (hospital) leader's practices towards safety. There is some recognition of the medical error problem and that leaders exhibit moderate levels of leadership practices to promote safety. There were no differences noted in unit and hospital leaders' behaviors, with the exception that unit leaders promote change and enable staff to act more often than hospital leaders. There were no statistically significant relationships between overall leadership, or individual leadership practices and the organization's safety performance. There was a significant relationship between leadership and safety performance when other factors in organizational culture were considered. Teaching and Magnet hospitals also exhibited stronger behaviors towards safety. Organizational culture, as measured by academic affiliation and Magnet recognition, is strongly related to safety performance as measured by the degree of development of a medication safety regime. ^

In this paper, we extend the debate concerning Credit Default Swap valuation to include time varying correlation and co-variances. Traditional multi-variate techniques treat the correlations between covariates as constant over time; however, this view is not supported by the data. Secondly, since financial data does not follow a normal distribution because of its heavy tails, modeling the data using a Generalized Linear model (GLM) incorporating copulas emerge as a more robust technique over traditional approaches. This paper also includes an empirical analysis of the regime switching dynamics of credit risk in the presence of liquidity by following the general practice of assuming that credit and market risk follow a Markov process. The study was based on Credit Default Swap data obtained from Bloomberg that spanned the period January 1st 2004 to August 08th 2006. The empirical examination of the regime switching tendencies provided quantitative support to the anecdotal view that liquidity decreases as credit quality deteriorates. The analysis also examined the joint probability distribution of the credit risk determinants across credit quality through the use of a copula function which disaggregates the behavior embedded in the marginal gamma distributions, so as to isolate the level of dependence which is captured in the copula function. The results suggest that the time varying joint correlation matrix performed far superior as compared to the constant correlation matrix; the centerpiece of linear regression models.

El presente trabajo, propone una revisión de la cerámica contemporánea, con especial referencia a la producción artística que hoy circula en los principales centros de producción internacional, a partir del intercambio académico realizado por la autora, en la Escuela Nacional Superior de Arte de Limoges, Francia, en febrero-mayo de 2006. La permanencia en este centro de estudios especializado posibilitó, además de la concreción de un proyecto artístico en porcelana, tomar contacto con la producción cerámica de otros países europeos y de oriente, por la vinculación que la institución francesa promueve como eje de su desarrollo y su oferta educativa. De allí la importancia de rescatar y valorar esta experiencia, con la finalidad de tomar conocimiento del estado actual de la cerámica artística y analizar en este contexto, la situación en nuestra región.

El presente trabajo se ocupa de desarrollar una reflexión sobre los textos testimoniales escritos por Rodolfo Walsh durante los años setentas abordando las cuestiones estéticas, ideológicas y políticas que suscita una operación de lectura que pone en juego las inflexiones en la trayectoria del autor y ciertos debates de la intelectualidad de izquierda argentina y latinoamericana. En tal sentido, se intentará dar cuenta tanto de las continuidades como de las modulaciones que presenta la escritura testimonial de Rodolfo Walsh luego de una inflexión identificada en torno a los años 1968-1969, atendiendo a las marcas de la configuración de su habitus, a su posicionamiento en el campo intelectual y a sus intervenciones en el terreno de la militancia política. De este modo se buscará indagar sobre las implicancias y propuestas estéticopolíticas que esos textos generan en torno a los vínculos entre escritura, literatura, testimonio y sectores subalternos. Mi lectura, entonces, se centra en las prácticas de escritura testimonial walshianas que, en tanto articulan una narrativa de la experiencia histórica de los sectores populares, cuestionan los modos de concebir y producir el ejercicio de lo literario en tiempos de revuelta.

Este trabajo forma parte de una investigación más amplia sobre la perspectiva de los indoamericanos sobre la invasión europea. Los europeos consistentemente se proyectan en las Crónicas de Indias como hombres blancos y hermosos ante los ojos de los indoamericanos. Aquí se presenta un tipo de micro historia indoamericana que mina la historia oficial al irse contraponiendo a lo establecido sobre la invasión de América en esos años. Se sigue una estética general de los indoamericanos según sus fuentes a través del continente usando el cabello como factor estético. Aunque en muchos casos las fuentes están "comprometidas" (y no podemos negar que la historia oficial también lo está), se ve una asombrosa consistencia en las diferentes versiones indoamericanas sobre los europeos de Norteamérica a Chile. Los indoamericanos rechazaron a los europeos, entre otras cosas por ser "cabelludos". El folkor americano forma una imagen-símbolo (los huecubuyes en Chile, el "un monstruo por venir" entre los michoacanos, y la Mala cosa en Norteamérica) de los cabelludos como rechazo de los invasores cabelludos europeos. Se les relaciona por lo tanto con los "animales salvajes" al unir su crueldad con su apariencia física cabelluda similar a los animales que los indoamericanos conocían. La barba pasa a ser una característica de fealdad extrema y de una indicación de deficiencia mental y física de los blancos. Se ve un rechazo a todo lo barbudo, incluyendo a los sacerdotes o a los santos barbudos de la iglesia. Es una visión general de los cabelludos como algo feo, malo y diabólico

O trabalho apresenta resultados de pesquisa acerca das políticas de educaçao no Brasil, do princípio regime de colaboraçao e da gestao da educaçao, apresentando, neste momento, aspectos da trajetória sociopolítica da elaboraçao ou adequaçao dos Planos Municipais de Educaçao (PMEs), deflagrada em 2013 pelo MEC/SASE, com as possibilidades de efetivaçao do regime de colaboraçao e da gestao democrática. Sua abordagem é qualitativa, de caráter teórico-empírico e exploratório, abarcando a documentaçao relativa aos PMEs dos Municípios. No Tocantins, até o início do ano de 2014, um georreferenciamento demonstra que dos 139 Municípios, apenas seis elaboraram seus PMEs. Neste contexto, predomina a visao de administraçao municipal restrita às suas instituiçoes escolares e ao tempo de sua gestao, sem relaçao ou articulaçao com metas nacionais comuns com vistas à materializaçao do Sistema Nacional de Educaçao. Deste processo, destaca-se o significativo movimento sociopolítico em torno do planejamento da educaçao no século XXI, enfrentado o desafio de definir o objetivo comum da educaçao brasileira. Entretanto, há ideias que merecem ser investigadas, como a sua concepçao de gestao e planejamento e as formas de colaboraçao estabelecidas
