La ciencia y la política : Dos aspectos intrínsecos del saber cartográfico argentino (1912-1941)

Un plan cartográfico es un proceso contradictorio en el cual intervienen decisiones técnicas y políticas que pueden cambiar e incluso modificar los objetivos iniciales del plan. Sin embardo, la historiografía clásica de la cartografía sostiene que la toma de tales decisiones es el resultado de medidas únicamente científicas y técnicas en las que no existen intereses ni contradicciones políticas. En este trabajo intentamos rastrear -en las etapas de la producción cartográfica argentina- los momentos en los que la ciencia y la política se entrelazan de tal manera que son constitutivas de la ciencia cartográfica. Para ello tomamos los proyectos cartográficos del IGM: el Plan de la Carta y la Carta Militar Provisional; y la determinación geodésica del DATUM altimétrico que se llevó a cabo en torno a la Comisión para la Medición del Arco de Meridiano

Maternal support for autonomy : relationships with persistence for children with Down syndrome and typically developing children

Maternal behaviors and child mastery behaviors were examined in 25 children with Down syndrome and 43 typically developing children matched for mental age (24–36 months). During a shared problem-solving task, there were no group differences in maternal directiveness or support for autonomy, and mothers in the two groups used similar verbal strategies when helping their child. There were also no group differences in child mastery behaviors, measured as persistence with two optimally challenging tasks. However, the two groups differed in the relationships of maternal style with child persistence. Children with Down syndrome whose mothers were more supportive of their autonomy in the shared task displayed greater persistence when working independently on a challenging puzzle, while children of highly directive mothers displayed lower levels of persistence. For typically developing children, persistence was unrelated to maternal style, suggesting that mother behaviors may have different causes or consequences in the two groups.

Advance Directives and the Promotion of Autonomy: a Comparative Australian Statutory Analysis

Legislation regulating advance directives exists in six Australian jurisdictions. In all of these jurisdictions, legislation was enacted to enshrine the common law right of a competent adult to refuse treatment in advance, even if that treatment was required to sustain life. It was thought that enshrining the common law would also enshrine the principle of autonomy on which the common law was based. This article explores whether this is the case by examining the legislative restrictions that are imposed on a competent adult who wishes to complete an advance directive refusing treatment. The article reviews the legislation in all Australian jurisdictions and concludes that, while many of the legislative restrictions can be justified, many cannot as they effectively erode rather than promote the right of a competent adult to refuse treatment.

Advance Directives Refusing Treatment as an Expression of Autonomy: Do the Courts Practise What They Preach?

The principle of autonomy is at the heart of the right of a competent individual to make an advance directive that refuses life-sustaining medical treatment, and to have that directive complied with by medical professionals. That right is protected by both the common law and, to an extent, by legislation that has been enacted in the United Kingdom and many jurisdictions in Australia. The courts have a critical role in protecting that autonomy, both in those jurisdictions in which the common law continues to operate, and in those jurisdictions which are now governed by statute, and in which judicial determinations will need to be made about legislative provisions. The problem explored in this article is that while the judiciary espouses the importance of autonomy in its judgments, that rhetoric is frequently not reflected in the decisions that are reached. In the United Kingdom and Australia, there is a relatively small number of decisions that consider the validity and applicability of advance directives that refuse life-sustaining medical treatment. This article critically evaluates all of the publicly available decisions and concludes that there is cause for concern. In some cases, there has been an unprincipled evolution of common law principles, while in others there has been inappropriate adjudication through operational irregularities or failure to apply correct legal principles. Further, some decisions appear to be based on a strained interpretation of the facts of the case. The apparent reluctance of some members of the judiciary to give effect to advance directives that refuse treatment is also evidenced by the language used in the judgments. While the focus of this article is on common law decisions, reference will also be made to legislation and the extent to which it has addressed some of the problems identified in this article.

Dragline automation - a decade of development : shared autonomy for improving mining equipment productivity

Draglines are massive machines commonly used in surface mining to strip overburden, revealing the targeted minerals for extraction. Automating some or all of the phases of operation of these machines offers the potential for significant productivity and maintenance benefits. The mining industry has a history of slow uptake of automation systems due to the challenges contained in the harsh, complex, three-dimensional (3D), dynamically changing mine operating environment. Robotics as a discipline is finally starting to gain acceptance as a technology with the potential to assist mining operations. This article examines the evolution of robotic technologies applied to draglines in the form of machine embedded intelligent systems. Results from this work include a production trial in which 250,000 tons of material was moved autonomously, experiments demonstrating steps towards full autonomy, and teleexcavation experiments in which a dragline in Australia was tasked by an operator in the United States.

Local autonomy, tax morale, and the shadow economy

Policymakers often propose strict enforcement strategies to fight the shadow economy and to increase tax morale. However, there is an alternative bottom-up approach that decentralises political power to those who are close to the problems. This paper analyses the relationship with local autonomy. We use data on tax morale at the individual level and macro data on the size of the shadow economy to analyse the relevance of local autonomy and compliance in Switzerland. The findings suggest that there is a positive (negative) relationship between local autonomy and tax morale (size of the shadow economy).

Law autonomy and advance directives

The principle of autonomy underpins legal regulation of advance directives that refuse life-sustaining medical treatment. The primacy of autonomy in this domain is recognised expressly in the case law, through judicial pronouncement, and implicitly in most Australian jurisdictions, through enactment into statute of the right to make an advance directive. This article seeks to justify autonomy as an appropriate principle for regulating advance directives and relies on three arguments: the necessity of autonomy in a liberal democracy; the primacy of autonomy in medical ethics discourse; and the uncontested importance of autonomy in the law on contemporaneous refusal of medical treatment. This article also responds to key criticisms that autonomy is not an appropriate organising principle to underpin legal regulation of advance directives.

Increasing underwater vehicle autonomy by reducing energy consumption

In this paper, we concern ourselves with finding a control strategy that minimizes energy consumption along a trajectory connecting two given configurations. We develop an algorithm, based on our previous work with the time optimal problem, which provides implementable control strategies that are energy efficient. We find an interesting correlation between the duration of these trajectories and the optimal duration. We present the algorithm, control strategy and experimental results from our test-bed vehicle.

Student autonomy enhancing science learning : Observations from a Primary Connections implementation

This case study involved a detailed analysis of the changes in beliefs and teaching practices of teachers who adopted the Primary Connections program as a professional development initiative. When implementing an inquiry-based learning model, teachers observed that their students learnt more when they intervened less. By scaffolding open-ended nquiries they achieved more diverse, complex and thorough learning outcomes than previously achieved with teacher-led discussions or demonstrations. Initially, student autonomy presented erceived threats to teachers, including possible selection of topics outside the teachers’ science knowledge. In practice, when such issues arose, resolving them became a stimulating part of the earning for both teachers and students. The teachers’ observation of enhanced student learning became a powerful motivator for change in their beliefs and practices. Implications for developers of PD programs are (1) the importance of modeling student-devised inquiries, and (2) recognising the role of successful classroom implementation in facilitating change.
