Leadership ethics and the problem of Dirty Hands in the political economy of contemporary Africa

Cet article discute des problèmes de gouvernance et de corruption en Afrique dans le cadre d’un débat politique et philosophique large entre universalisme et relativisme, idéalisme et réalisme, ainsi que entre individualisme et communautarisme. Premièrement, je défends que l’approche réaliste de l’éthique politique et du leadership ne permet pas de différencier entre les éléments descriptifs et prescriptifs de la gouvernance et peut aisément être utilisée pour justifier « les Mains Sales » des dirigeants au nom de l’intérêt supérieur de la nation, même dans les cas où l’intérêt personnel est la seule force motivationnelle pour les actions qui sapent les codes sociaux et éthiques ordinaires. Deuxièmement, l’article montre la faillite de la confiance publique dans le gouvernement et la faiblesse de l’Etat renforce les politiques communautariennes sub-nationales qui tendent à être fondées sur l’ethnie et exclusive, et par conséquent, qui viole le cœur de l’éthique publique, c’est-à-dire l’impartialité. Finalement, l’article suggère que les principes d’éthique universels pour les services publiques soient introduits en complément plutôt qu’en concurrence avec les éthiques locales, socialement et culturellement limitée au privé. Cela requière, d’une part, que nous comprenions mieux la complexité historique, les circonstances économiques et sociales et les arrangements politiques transitionnels dans les pays africains. D’autre part, un nous devons investir dans une éducation éthique civique et professionnel réflexive qui adopte un point de vue nuancé entre le réalisme politique et l’idéalisme comme point de départ des réformes institutionnelles, aussi bien que modalité de changement des comportements à long terme.

Propiedades psicométricas del test de competencias motoras Bruininks Oseretsky en versión corta para niños entre 4 y 7 años en Chía y Bogotá – Colombia.

Existen importantes pruebas de valoración que miden habilidades o competencias motoras en el niño; a pesar de ello Colombia carece de estudios que demuestren la validez y la confiabilidad de un test de medición que permita emitir un juicio valorativo relacionado con las competencias motoras infantiles, teniendo presente que la intervención debe basarse en la rigurosidad que exigen los procesos de valoración y evaluación del movimiento corporal. Objetivo. El presente estudio se centró en determinar las propiedades psicométricas del test de competencias motoras Bruininiks Oseretsky –BOT 2- segunda edición. Materiales y métodos. Se realizó una evaluación de pruebas diagnósticas con 24 niños aparentemente sanos de ambos géneros, entre 4 y 7 años, residentes en las ciudades de Chía y Bogotá. La evaluación fue realizada por 3 evaluadores expertos; el análisis para consistencia interna se realizó utilizando el Coeficiente Alfa de Cronbach, el análisis de reproducibilidad se estableció a través del Coeficiente de Correlación Intraclase –CCI- y para el análisis de la validez concurrente se utilizó el Coeficiente de Correlación de Pearson, considerando un alfa=0.05. Resultados. Para la totalidad de las pruebas, se encontraron altos índices de confiabilidad y validez. Conclusiones. El BOT 2 es un instrumento válido y confiable, que puede ser utilizado para la evaluación e identificación del nivel de desarrollo en que se encuentran las competencias motoras en el niño.

Information processing: US Patent 4,409,617

An information processor for rendering input data compatible with standard video recording and/or display equipment, comprizing means for digitizing the input data over periods which are synchronous with the fields of a standard video signal, a store adapted to store the digitized data and release stored digitized data in correspondence wiht the line scan of a standard video monitor, the store having two halves which correspond to the interlaced fields of a standard video signal and being so arranged that one half is filed while the other is emptied, and means for converting the released stored digitized data into video luminance signals. The input signals may be in digital or analogue form. A second stage which reconstitutes the recorded data is also described.

Shaking hands: Priming by social action effects

In a semi-naturalistic response-effect compatibility paradigm, participants were given the opportunity to learn that hand-shaking actions would be followed by social effects (human hand-shaking stimuli from a third-person perspective) or inanimate effects (block arrow stimuli). Relative to the actions, these effects appeared on the same or the opposite side of the screen (positional compatibility), and pointed towards or away from the response hand (directional compatibility). After learning, response times indicated a positional compatibility effect for both social and inanimate effects, but a directional compatibility effect occurred only for social action effects. These findings indicate that actions can be represented, not only by their effects on the inanimate world, but also by their effects on the actions of others. They are consistent with ideomotor theory, and with the view that actions are represented by bidirectional response-effect associations. They also have implications with respect to the origins and on-line control of imitation and the systems supporting imitation.

A survey of multi-fingered robot hands: issues and grasping achievements

Recently a substantial amount of research has been done in the field of dextrous manipulation and hand manoeuvres. The main concern has been how to control robot hands so that they can execute manipulation tasks with the same dexterity and intuition as human hands. This paper surveys multi-fingered robot hand research and development topics which include robot hand design, object force distribution and control, grip transform, grasp stability and its synthesis, grasp stiffness and compliance motion and robot arm-hand coordination. Three main topics are presented in this article. The first is an introduction to the subject. The second concentrates on examples of mechanical manipulators used in research and the methods employed to control them. The third presents work which has been done on the field of object manipulation.

Within, but not between hands interactions in vibrotactile detection thresholds reflect somatosensory receptive field organization

Detection of a tactile stimulus on one finger is impaired when a concurrent stimulus (masker) is presented on an additional finger of the same or the opposite hand. This phenomenon is known to be finger-specific at the within-hand level. However, whether this specificity is also maintained at the between-hand level is not known. In four experiments, we addressed this issue by combining a Bayesian adaptive staircase procedure (QUEST) with a two-interval forced choice (2IFC) design in order to establish threshold for detecting 200ms, 100Hz sinusoidal vibrations applied to the index or little fingertip of either hand (targets). We systematically varied the masker finger (index, middle, ring, or little finger of either hand), while controlling the spatial location of the target and masker stimuli. Detection thresholds varied consistently as a function of the masker finger when the latter was on the same hand (Experiments 1 and 2), but not when on different hands (Experiments 3 and 4). Within the hand, detection thresholds increased for masker fingers closest to the target finger (i.e., middle>ring when the target was index). Between the hands, detection thresholds were higher only when the masker was present on any finger as compared to when the target was presented in isolation. The within hand effect of masker finger is consistent with the segregation of different fingers at the early stages of somatosensory processing, from the periphery to the primary somatosensory cortex (SI). We propose that detection is finger-specific and reflects the organisation of somatosensory receptive fields in SI within, but not between the hands.

Influência da chuva na eficácia do herbicida 2,4-D no controle de Myriophyllum aquaticum

O objetivo deste estudo foi avaliar a eficiência de controle de duas doses do herbicida 2,4-D pulverizado em plantas de M. aquaticum e submetido à simulação de chuva em diferentes períodos de tempo após sua aplicação. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições, disposto em um esquema fatorial 2 x 8 (duas doses de herbicida e oito intervalos de chuva). Utilizou-se o herbicida 2,4-D, na formulação comercial DMA 806, em duas doses: 670 e 1.340 g e.a. ha-1. A simulação de uma chuva de 15 mm, com duração de cinco minutos, foi realizada em oito intervalos de tempo após a pulverização do herbicida (0,25h, 0,5h, 1h, 2h, 4h, 8h, 12h e sem chuva). Foram realizadas avaliações visuais de controle aos 7, 14, 21 e 28 dias após a aplicação dos tratamentos. As duas doses avaliadas do herbicida 2,4-D foram eficientes no controle das plantas de M. aquaticum, mesmo com ocorrência de chuva 15 minutos após sua aplicação.
