Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time, and attempts to address it require a clear understanding of how ecological communities respond to environmental change across time and space. While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes, vast areas of the tropics remain understudied. In the American tropics, Amazonia stands out as the world's most diverse rainforest and the primary source of Neotropical biodiversity, but it remains among the least known forests in America and is often underrepresented in biodiversity databases. To worsen this situation, human-induced modifications may eliminate pieces of the Amazon's biodiversity puzzle before we can use them to understand how ecological communities are responding. To increase generalization and applicability of biodiversity knowledge, it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region's vulnerability to environmental change. 15%–18% of the most neglected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lost

The Performativity of Code : Software and Cultures of Circulation

This article analyses a specific piece of computer code, the Linux operating system kernel, as an example of how technical operationality figures in contemporary culture. The analysis works at two levels. First of all, it attempts to account for the increasing visibility and significance of code or software-related events. Second, it seeks to extend familiar concepts of performativity to include cultural processes in which the creation of meaning is not central, and in which processes of circulation play a primary role. The analysis concentrates on the practices and patterns of circulation of Linux through versions, distributions, clones and reconfigurations. It argues that technical ‘culture-objects’ such as Linux take on a social existence within contemporary technological cultures because of the authorizing contexts in which the reading, writing and execution of code occur. The ‘force’ or performance of certain technical objects, their operationality, can be understood more as the stabilized nexus of diverse social practices, rules and personae than as a formal property of the objects themselves

A satisfação do usuário em hospital universitário User satisfaction at a university hospital

São apresentados resultados de uma pesquisa exploratória da satisfação/insatisfação de 158 pacientes que recorreram a um Hospital Universitário (HUPE) para consulta inicial. As entrevistas foram feitas por alunos do primeiro ano, como parte de projeto de inserção precoce do mesmo com a prática médica, acompanhando pacientes como observadores. Foi utilizado questionário que cobriu os vários aspectos do problema: variáveis sócio-demográficas, arte do cuidado, resolutividade da consulta médica, sugestões de melhoria dos serviços. Tanto alunos/observadores como os usuários conseguiram perceber com precisão os problemas do processo do atendimento (recepção, matrícula, consulta, enfermagem, serviço social, farmácia, exames complementares) mas houve divergência de opinião entre vários aspectos da satisfação/insatisfação entre alunos e usuários, provavelmente devido às origens sociais diferentes e expectativas diversas.<br>The results of a research project into the level of satisfaction/dissatisfaction of 158 first-time patients attending by an University hospital, Brazil, are presented. The interviews were carried out by first year medical students as part of a comprehensive project concerned with the restructuring of the Medical Curriculum. Its prime objective was to expose the students to patients/consumers as early as possible in their studies. After an introductory training program, the students asked the patients arriving at the hospital out-patient clinic for permission to observe them throughout the attendance given. A questionnaire was used which covered the various aspects of the consumers relationship with a medical institution (socio-economic variables, "art of care", outcome of the medical encounter and suggestions for improvement). Both patients and students were able to perceive the different problems that patients confront in the course of their dealings with a medical institution (reception, registration, nursing, social service and medical attention). The data showed a difference of opinion between students and patients regarding several aspects of the satisfaction/dissatisfaction items, partly because of their different social class status and parthy due to the different expectations regarding medical care
