Charles Darwin on his voyage aboard H. M. S. Beagle contracted a mysterious illness that persisted throughout his life. Despite being ill, he continued his writings. He is remembered as the scientist who putforth the theory that species are changing. A species evolves by the accumulation and preservation of successive slight favourable variations, now known as mutations. In his quest to strengthen his theory on the common origin of all life, and evolution by natural selection, he increasingly turned to plants and carried out experiments at his home-cum-laboratory, focusing on phenomena commonly associated with animals namely, movement. In plant roots, seedlings and climbing plants, he described nyctitropism, geotropism, phototropism and circumnutation. Darwin described the sleep movements in plants in which the petiole hangs down and the leaflets press together in the evening.

Un grupo de estudiantes de un instituto de Sevilla realizan un viaje de siete días al Reino Unido para conocer la huella científica que dejó Darwin. A partir de una exposición dedicada a este científico, se diseña una ruta, para la cual el alumnado realiza cuatro tareas. La primera es la práctica lingüística de expresión oral. La segunda sería la competencia lectora, cada alumno lee una biografía de Darwin adaptada. La tercera es el tratamiento de la información que consiste en la recopilación de datos sobre Charles Darwin en varias ciudades. Y la última es la investigadora, por grupos localizan los lugares en los que estuvo y las actividades que se pueden realizar en los mismos.

Erasmus Darwin (1731-1802) apresentou suas ideias evolutivas principalmente no fim do século XVIII. No entanto, elas não foram consideradas na época. Seu neto, Charles Darwin (1809-1882), na 6ª edição do Origin of species as avaliou de modo negativo, comparando-as às concepções equivocadas de Lamarck. O objetivo desta dissertação é inicialmente, descrever as concepções de hereditariedade e evolução de Erasmus, considerando o contexto de sua época. Além disso, procura esclarecer se o tratamento recebido se deveu a uma proposta fraca ou se ela mereceria uma maior consideração. Esta dissertação contém uma Introdução e quatro capítulos. O Capítulo 1 discute a vida, trabalhos e contexto em que Erasmus apresentou suas ideias. O Capítulo 2 lida com as concepções de herança e evolução presentes em Zoonomia. O Capítulo 3 discute sobre as concepções de Erasmus sobre a transformação das espécies nas plantas. O Capítulo 4 compara as concepções evolutivas de Erasmus com as de Lamarck. O Capítulo 5 procura responder às perguntas colocadas no início desta pesquisa e apresenta algumas considerações finais sobre o assunto discutido. Esta pesquisa leva à conclusão de que a transmutação das espécies não era o principal interesse de Erasmus. Ele não ofereceu uma fundamentação empírica para suas ideias. Este fato, juntamente com a situação sócio-político-religiosa da época, muito provavelmente contribuiu para a recepção sofrida. Além disso, embora existam algumas semelhanças entre as propostas de Erasmus e Lamarck, existem também grandes diferenças tais como a abrangência da pesquisa, o espaço dedicado à discussão das ideias, a fundamentação oferecida, dentre outras. Erasmus não propôs uma teoria coerente lidando com desde a origem da vida até o aparecimento do homem como Lamarck. Ele somente apresentou algumas ideias a esse respeito em obras dedicadas a outros assuntos.

The Genius of Erasmus Darwin provides insight into the full extent of Erasmus Darwin's exceptional intellect. He is shown to be a major creative thinker and innovator, one of the minds behind the late eighteenth-century industrial revolution, and one of the first, if not the first, to perceive the living world (including humans) as part of a unified evolutionary scenario. The contributions here provide contextual understandings of Erasmus Darwin's thought, as well as studies of particular works and accounts of the later reception of his writings. In this way it is possible to see why the young Samuel Taylor Coleridge was moved to describe Darwin as 'the first literary character in Europe, and the most original-minded man'. Erasmus Darwin, Charles Darwin's grandfather, was one of the leading intellectuals of eighteenth-century England. He was a man with an extraordinary range of interests and activities: he was a doctor, biologist, inventor, poet, linguist, and botanist. He was also a founding member of the Lunar Society, an intellectual community that included such eminent men as James Watt and Josiah Wedgwood.

The discourse surrounding recent Aboriginal social policy regularly refers to pragmatism and partnership. In a simpler world, we might call this ‘getting things done with Aboriginal people.’ To that extent, the discourse draws on an indisputable common sense, and it is not surprising that a variety of political agendas can be packaged within such language. While many things need to be done, the quantity and particularly the quality of social networks required to take effective policy into effective practice is something we ought to consider more carefully. This is where the concept of social capital could be useful, since it focuses attention on the social resources required to construct social policy, as well as the social resources that could be produced by effective social policy. Partnerships and pragmatism are therefore related at a most fundamental level in terms of social policy. We question whether this important conceptual bedrock has been fully explored. Hence we review here some recent ‘big plans’ for Aboriginal Australia, and ask whether the size of the theory matches the size of the plans.

The Tiddas Showin’ Up, Talkin’ Up and Puttin’ Up: Indigenous Women and Educational Leadership project was led by Flinders University in partnership with the Australian Catholic University through the Indigenous Higher Education Centres located in Adelaide (Yunggorendi First Nations Centre) and Brisbane (Weemala Indigenous Unit) (Bunda and White 2009). At the beginning of the project, two levels of governance were established: a Circle of Senior Indigenous Women from the higher education sector, and a Steering Committee of Senior Executive Women from partner universities. The Circle of Senior Indigenous Women included experts in the fields of learning and teaching, scholarship, administration and management, and community engagement. The Circle’s members were: • Professor Wendy Brady, Charles Darwin University • Dr Jackie Huggins, University of Queensland • Ms Angela Leitch, Education Queensland • Professor Aileen Moreton-Robinson, Queensland University of Technology • Dr Bronwyn Fredericks, Queensland University of Technology and Monash University The Steering Committee members were: • Professor Gabrielle McMullen, Australian Catholic University • Professor Marie Emmit, Australian Catholic University • Professor Faith Trent, Flinders University • Dr Jane Robbins, Flinders University The two levels of governance provided advice to the project leaders throughout the project. Three of these women share their reflections in this paper.

Purpose - Since the beginning of human existence, humankind has sought, organized and used information as it evolved patterns and practices of human information behaviors. However, the field of human information behavior (HIB) has not heretofore pursued an evolutionary understanding of information behavior. The goal of this exploratory study is to provide insight about the information behavior of various individuals from the past to begin the development of an evolutionary perspective for our understanding of HIB. Design/methodology/approach - This paper presents findings from a qualitative analysis of the autobiographies and personal writings of several historical figures, including Napoleon Bonaparte, Charles Darwin, Giacomo Casanova and others. Findings - Analysis of their writings shows that these persons of the past articulated aspects of their HIB's, including information seeking, information organization and information use, providing tangible insights into their information-related thoughts and actions. Practical implications - This paper has implications for expanding the nature of our evolutionary understanding of information behavior and provides a broader context for the HIB research field. Originality/value - This the first paper in the information science field of HIB to study the information behavior of historical figures and begin to develop an evolutionary framework for HIB research. © Emerald Group Publishing Limited.
