Poder e influencia en el liderazgo transformacional

Como proyecto de grado, el presente trabajo consiste en una revisión teórica de los conceptos de liderazgo, poder e influencia, junto con las posibles relaciones que entre ellos se pueden presentar. Para ello, cada concepto es definido de manera individual, y con base en ello, se identifica la dependencia que tienen estos conceptos entre sí y la importancia dentro del desarrollo del liderazgo transformacional actual. Para lograr lo propuesto, se llevó a cabo la revisión de una parte de la literatura académica presente en libros, revistas académicas, bases de datos y documentos relacionados con los temas y conceptos tratados. A partir de ello, se entendió la evolución del concepto del liderazgo y los enfoques presentados desde la década de los 1920´s hasta la actualidad, junto con el modelo de rango total y el tipo transaccional y transformacional del liderazgo, para luego definir el papel y la importancia de los conceptos de poder, los tipos de poder, la influencia y las tácticas de influencia, y así, identificar las posibles relaciones que se presentan entre los conceptos y la importancia de estos en el entorno organizacional actual.

La cultura : energía renovadora para alcanzar los objetivos de desarrollo del milenio

Este documento revisa los vínculos entre desarrollo y cultura, haciendo particular énfasis en el rol que ésta tiene en el logro de los Objetivos de Desarrollo del Milenio (ODM). El argumento principal es que los ODM son un proceso frágil, sujeto a los cambios en las políticas nacionales, a los ciclos de la economía mundial y a los efectos del cambio climático. En este sentido, la cultura se considera energía renovadora para el logro sostenido de los ODM. Utilizando como fuente el informe de la ONU sobre los ODM de junio de 2010, revisando literatura sobre relaciones entre cultura y desarrollo, y recopilando algunas evidencias de distintas partes del mundo, en las que la cultura contribuye a alcanzar los ODM, se obtuvieron resultados que ratifican la importancia de la cultura como medio y fin del desarrollo. De igual forma, se reclama la necesidad de que la cultura sea reconocida de manera explícita en los ODM y se incorpore a ellos de manera transversal

The re-urbanization of the city center of Manaus , Brazil - Facing the challenges of informal settlements

Illegal occupation of urban land in Brazil is a widespread phenomenon. Slum dwellers are excluded from the attributes of urban citizenship although they provide the labor force required by low productivity urban services needed by cities. Illegal settlements generate multiple problems for the rest of the city . Its solution is of key relevance to the city in general but also provide an opportunity for the social and economic advancement of slum dwellers. The programs required to attain these results are complex and difficult to implement underscoring the challenges countries will face to attain the Millennium Development Goals of reducing the population living in slums.

A formação inicial dos Professores do Ensino Primário no Portugal do Século XX (1942-2000). Do modelo maternal ao modelo profissional

Pensamos com este nosso trabalho de investigação contribuir para o estudo da formação inicial dos professores do ensino primário/professores do 1º ciclo do ensino básico (1942-2000), tomando como eixo a evolução dos conceitos educação, professor, aprendizagem, sintetizados no modelo maternal, em que a professora governava a sua classe como a mãe a sua família e no modelo profissional que faz do professor um expert e insiste na sua competência, quer a nível dos saberes, quer a nível das técnicas pedagógicas. Escolhemos como referente inicial do nosso estudo o ano de 1942, data em que, pelo decreto-lei nº 32 243 de 5 de Setembro de 1942, são reabertas as Escolas do Magistério Primário em Lisboa, Porto, Coimbra e Braga. Escolhemos como referente final do nosso estudo o ano de 2000, fecho de século e milénio que, na formação inicial de professores, inseriu os primeiros professores do 1º ciclo do ensino básico com licenciatura (decreto-lei nº 115, de 19 de Setembro de 1997). No percurso da formação inicial dos professores do Ensino Primário, da reabertura das Escolas do Magistério Primário (1942), à instituição das Escolas Superiores de Educação (1986), à promulgação do Estatuto da Carreira Docente (1990), à exigência do grau de licenciatura na formação inicial dos professores do 1º ciclo (1997) questionamos: - Que conceitos de educação, professor e aprendizagem estão presentes na formação inicial realizada em Escolas do Magistério Primário e Escolas Superiores de Educação? - Que transformações sofrem estes conceitos com a adopção de novos modelos de formação inicial experimentados a partir da Revolução Portuguesa de 25 de Abril de 1974?

Os «objetivos do milénio» e a reforma da ONU

Os «objetivos do Milénio» constituem um dos maiores desafios com que a Humanidade está confrontada. Retirar da pobreza extrema quase dois biliões de pessoas e conferir-lhes condições para a existência de uma vida condigna constituíram um propósito assumido por 191 países sob impulso da ONU e de um homem em particular: Kofi Annan. Perceber se esta organização está em condições de poder assumir a coordenação da implementação dos objetivos promovendo em simultâneo a reforma da ONU, reclamada por Kofi Annan como essencial para a prossecução destes objectivos, é o que se pretende com esta reflexão.

Granulometric characterization and evaluation of annually banded mid-Holocene estuarine silts, Welsh Severn Estuary (UK): coastal change, sea level and climate

Holocene silts (salt marshes) and highest intertidal-supratidal peats are superbly exposed on a 15 kin coastal transect which reveals two laterally extensive units of annually banded silts (Beds 3, 7) associated with three transgressive-regressive silt-peat cycles (early sixth-early fourth millennium BC). Bed 3 in places is concordantly and gradationally related to peats above and below, but in others transgresses older strata. Bed 7 also grades up into peat, but everywhere overlies a discordance. The banding in Bed 3 at three main and two minor sites was resolved and characterized texturally at high-resolution (2.5/5 mm contiguous slices) using laser granulometry (LS230 with PIDS) and a comprehensive scheme of data-assessment. Most of Bed 3 formed very rapidly, at peak values of several tens of millimetres annually, in accordance with modelled effects of sea-level fluctuations on mature marshes (bed concordant and gradational) and on marshes growing up after coastal erosion and retreat (bed with discordant base). Using data from the modern Severn Estuary, the textural contrast within bands, and its variation between bands, points to a variable but overall milder mid-Holocene climate than today. The inter-annual variability affected marsh dynamics, as shown by the behaviour of the finely divided plant tissues present. Given local calibration, the methodology is applicable to other tidal systems with banded silts in Britain and mainland northwest Europe. (c) 2006 Elsevier Ltd. All rights reserved.

Water management in Minoan Crete, Greece: the two cisterns of one Middle Bronze Age settlement

The two earliest structures of Minoan Crete that may be considered as large cisterns were both built in the first half of the second millennium BC (the time of the first Minoan palaces) at Myrtos-Pyrgos (lerapetra). A considerable feat of engineering and social management, they remain a most unusual attribute of a Minoan settlement, all the more so since the Myrtos river is/was available to supply water at the foot of the hill of Pyrgos. This paper presents these cisterns, briefly, in terms of geology and technology, the history of their use and re-use, and their relevance to understanding the culture and society (at local and regional levels) of Crete in the time of the Old Palaces, as well as their possible contribution to the political and military history of the period. I then review possible precursors of, and architectural parallels to, the Pyrgos cisterns at Knossos, Malia and Phaistos (none of which has been proved to be a cistern), and the later history of cisterns in Bronze Age Crete. Since only three others are known (at Archanes, Zakro and Tylissos, of Late Bronze Age date), the two cisterns of Myrtos-Pyrgos are an important addition to our still rudimentary knowledge of how the Bronze Age Cretans managed their water supplies.

Producing Inequalities: Regional Sequences in Later Prehistoric Southern Spain

This paper presents regional sequences of production, consumption and Social relations ill Southern Spain from the beginning of the Neolithic to the Early Bronze Age (c. 5600-1550 BC). The regions Studied are southeast Spain, Valencia, the southern Meseta and central/western Andalucia. The details presented for each region and period vary in quality but Show how Much our knowledge of the archaeological record of southern Spain has changed during the last four decades. Among the Surprises are the rapidity of agricultural adoption. the emergence of regional centres of aggregated population in enclosed/fortified settlements of up to 400 hectares in the fourth and third millennia BC. the use of copper objects as instruments of production, rather than as items With 11 purely symbolic of 'prestige' value, large-scale copper production in western Andalucia in the third millennium BC (as opposed to the usual domestic production model), and the inference of societies based oil relations of class.

Chronology for the Aegean Late Bronze Age 1700-1400 BC

Radiocarbon (carbon-14) data from the Aegean Bronze Age 1700-1400 B.C. show that the Santorini (Thera) eruption must have occurred in the late 17th century B.C. By using carbon-14 dates from the surrounding region, cultural phases, and Bayesian statistical analysis, we established a chronology for the initial Aegean Late Bronze Age cultural phases (Late Minoan IA, IB, and II). This chronology contrasts with conventional archaeological dates and cultural synthesis: stretching out the Late Minoan IA, IB, and II phases by similar to 100 years and requiring reassessment of standard interpretations of associations between the Egyptian and Near Eastern historical dates and phases and those in the Aegean and Cyprus in the mid-second millennium B.C.

A reconfigurable neural environment on active networks

This paper proposes the deployment of a neural network computing environment on Active Networks. Active Networks are packet-switched computer networks in which packets can contain code fragments that are executed on the intermediate nodes. This feature allows the injection of small pieces of codes to deal with computer network problems directly into the network core, and the adoption of new computing techniques to solve networking problems. The goal of our project is the adoption of a distributed neural network for approaching tasks which are specific of the computer network environment. Dynamically reconfigurable neural networks are spread on an experimental wide area backbone of active nodes (ABone) to show the feasibility of the proposed approach.

African climate change: Taking the shorter route

Numerous factors are associated with poverty and underdevelopment in Africa, including climate variability. Rainfall, and climate more generally, are implicated directly in the United Nations “Millennium Development Goals” to eradicate extreme poverty and hunger, and reduce child mortality and incidence of diseases such as malaria by the target date of 2015. But, Africa is not currently on target to meet these goals. We pose a number of questions from a climate science perspective aimed at understanding this background: Is there a common origin to factors that currently constrain climate science? Why is it that in a continent where human activity is so closely linked to interannual rainfall variability has climate science received little of the benefit that saw commercialization driving meteorology in the developed world? What might be suggested as an effective way for the continent to approach future climate variability and change? We make the case that a route to addressing the challenges of climate change in Africa rests with the improved management of climate variability. We start by discussing the constraints on climate science and how they might be overcome. We explain why the optimal management of activities directly influenced by interannual climate variability (which include the development of scientific capacity) has the potential to serve as a forerunner to engagement in the wider issue of climate change. We show this both from the perspective of the climate system and the institutions that engage with climate issues. We end with a thought experiment that tests the benefits of linking climate variability and climate change in the setting of smallholder farmers in Limpopo Province, South Africa.
