    Chilean social workers and job satisfaction: The impact of psychological states and role stress
    (SAGE PUBLICATIONS LTD, 2012) Flores, Rodrigo; Miranda, Paula; Munoz, Carolina; Sanhueza, Guillermo
    The main goals of this study were to compare levels of job satisfaction (JS) between social workers from private and public organizations. Findings showed significant differences in scores for job satisfaction, psychological states, and role stress between the two groups.

    Pacifying seaweed: imagining docile objects for novel blue bioeconomies
    (2024) Ureta, Sebastian; Flores, Patricio; Barrena, Jose; Miranda, Paula
    In recent years the blue bioeconomy has been presented as a way for marine-based industries to break with traditional models of relentless resource extraction and extensive damage on marine ecosystems. Centering in innovation and biotechnological enhancement, the concept promises a future that makes compatible continual economic growth with environmental sustainability. In practice, however, the blue bioeconomy still mostly an object of imagination than a reality. In this paper we analyze a leading cause for such lack of effectiveness: the reductionistic ways in which most blue bioeconomy proposals engage with the agencies of marine entities. Adopting an analytical frame from science and technology studies (STS), we understand the multiple strategies oriented to produce neat and simple versions of marine beings as forms of "pacification" that enable the transformation of these beings in commodities that could be easily traded in global markets, at the expense of their sociobiological complexity. To explore the ways in which pacification works, the paper analyzes current attempts at renovating the seaweed industry in Chile. Especially we analyze two policy proposals - one focused on turning seaweed into the basis of a blue carbon economy and the other centered on the potential of seaweed as high-end novel foods for export - showing how they produce a highly pacified versions of seaweed that bear little resemblance with the complex beings populating Chilean seas. Pacified seaweed comes handy for market-oriented policy proposals but tend to fare quite poorly beyond them.

    Trasplante hepático: Evolución, curva de aprendizaje y resultados después de los primeros 300 casos
    (2019) Francisco Guerra, Juan; Luis Quezada, Jose; Cancino, Alejandra; Arrese, Marco; Wolff, Rodrigo; Benitez, Carlos; Carlos Pattillo, Juan; Cristobal Gana, Juan; Concha, Mario; Cortinez, Luis; Vera, Magdalena; Miranda, Paula; Rubilar, Francisco; Troncoso, Andres; Briceno, Eduardo; Dib, Martin; Jarufe, Nicolas; Martinez, Jorge
    Background: Liver transplantation (LT) is an option for people with liver failure who cannot be cured with other therapies and for some people with liver cancer. Aim: To describe, and analyze the first 300 LT clinical results, and to establish our learning curve. Material and Methods: Retrospective cohort study with data obtained from a prospectively collected LT Program database. We included all LT performed at a single center from March 1994 to September 2017. The database gathered demographics, diagnosis, indications for LT, surgical aspects and postoperative courses. We constructed a cumulative summation test for learning curve (LC-CUSUM) using 30-day post-LT mortality. Mortality at 30 days, and actuarial 1-, and 5-year survival rate were analyzed. Results: A total of 281 patients aged 54 (0-71) years (129 women) underwent 300 LT. Ten percent of patients were younger than 18 years old. The first, second and third indications for LT were non-alcoholic steatohepatitis, chronic autoimmune hepatitis and alcoholic liver cirrhosis, respectively. Acute liver failure was the LT indication in 51 cases (17%). The overall complication rate was 71%. Infectious and biliary complications were the most common of them (47 and 31% respectively). The LC-CUSUM curve shows that the first 30 patients corresponded to the learning curve. The peri-operative mortality was 8%. Actuarial 1 and 5-year survival rates were 82 and 71.4%, respectively. Conclusions: Outcome improvement of a LT program depends on the accumulation of experience after the first 30 transplants and the peri-operative mortality directly impacted long-term survival.
