Rapid Transformation

Currently, the destruction of landscapes is taking place with a decrease in the sustainability and productivity of natural ecosystems. One of the main reasons for this is inadequate environmental management, which, as a rule, is based on inadequate outdated theoretical ecological concepts. The totality of accumulated data shows that real ecosystems can be in several alternative states and demonstrate relatively rapid changes in the regime of existence with significant, abrupt and permanent changes in structure and functioning. In this regard, the main ecosystem paradigm is currently being revised. From the theoretical concept of the unicity of the ecosystem stable state, ecology moves to the concept of the multiplicity of stable states in the ecosystem. The dynamics of ecosystems can be represented, according to K. Holling, in the form of an adaptation cycle with the alternation of four phases, the features of which are considered. The importance of no return points and possible uncertainty in the dynamics of ecosystems are shown. Ecosystems, in a certain sense, have memory, which is the reason for the hysteresis effect during multidirectional changes in systems. The necessity of developing approaches of adaptive ecosystem management based on this concept is shown. Which is especially important in cases of rapid transformation of natural ecosystems, such, as an example, in the Crimea after the cessation of the supply of Dnieper water to the North Crimean canal. The difficulties of transition to adaptive environmental management in modern conditions are analyzed.

ABSTRACTThis study aims to investigate how lessons Field Practices in Terrestrial Ecosystems can contribute to the process of education and high school students of Ecology of Learning. We will seek to highlight how these activities can contribute to the construction of problematizations and Learning generating questions. For this we follow the process of signification ecological concepts developed in Campo classes in Natural Ecosystems. The research activities were held with high school students in the discipline of biology in a state school in the city of Ilha Comprida / SP. In this research work with ecological concepts planned for the high school. The didactic sequence presented involved the presentation of natural phenomena. The project generator theme were the Terrestrial Ecosystem Ilha Comprida. Because it is an island sandbank presents many coastal ecosystems of the Atlantic Forest with unique characteristics. Close spatially and physically limited on the northwestern coast by the Small Sea (estuary) and the southeast coast of the Atlantic Ocean. The city has well preserved vegetation. This makes Long Island a great "lab" didactic for teaching ecology of learning.RESUMOEste trabalho tem como objetivo investigar como as Aulas Práticas de Campo em Ecossistemas Terrestres podem contribuir para o processo de Ensino e Aprendizagem de Ecologia de estudantes do ensino médio. Buscaremos evidenciar como essas atividades podem contribuir para a construção de problematizações e perguntas geradoras de Aprendizagem. Para isso acompanhamos o processo de significação de conceitos ecológicos desenvolvidos em Aulas de Campo em Ecossistemas Natu-rais. As atividades de pesquisa foram realizadas com os alunos de ensino médio na disciplina de Biologia numa Escola Estadual no município de Ilha Comprida/SP. Nesta pesquisa trabalhamos com os conceitos de ecologia previstos para o ensino médio. A sequência didática apresentada envolveu a apresentação de fenômenos naturais. O tema gerador do projeto foram os Ecossis-temas Terrestres de Ilha Comprida. Por se tratar de uma ilha de restinga, apresenta diversos ecossistemas costeiros de Mata Atlântica com características singulares. Próximos espacialmente, e limitados fisicamente na costa noroeste pelo Mar Pequeno (estuário) e na costa sudeste pelo Oceano Atlântico. O município apresenta cobertura vegetal bem conservada. Tudo isto torna Ilha Comprida um ótimo “laboratório” didático para o ensino aprendizagem de ecologia. Contato principal: [email protected]

Bauxite excavation and the inert material quarries, in the wider region of the "National Park of Iti" in combination with the forest fires, the illegal logging, the grazing and the uncontrollable waste disposal, constituted the most important pressures in it's natural ecosystems. Particularly, bauxite ore exploitation that presented elation during the decade of '70s, was implemented without planning and it caused alterations in the natural environment of the region mainly by the continuous excavations, the foreheads of galleries and the extensive depositions of aggregates materials. As a result, all the above led to the occupation or the deforestation of forests and woodlands, the interruption of natural relief continuity and the change of natural géomorphologie processes. The aim of this work, concerns the determination of the impacts to the environment and more specifically the geomorphes and geomorphological processes, by the bauxite ore exploitation and the quarrying activity, that was developed in the wider region of the "National Park of Iti".

Efficient Learning

The future of online learning may be more than technology integration or increasing demands; it has to be humane and sustainable. Project management aiming to provide better online learning environments has to integrate sustainability into its vision and action in order not to burden future generations with careless creations of products or processes. This integration can be achieved by treating nature as a model and mentor and ecology provides the framework for this treatment. The first step towards realizing humane and sustainable online learning environments is to define the online learning ecosystem based on the characteristics of natural ecosystems; the external inputs, producers, consumers, decomposers, organic, and inorganic compounds. Once this ecosystem is defined, the managerial vision and strategies based on ecosystem management principles can be formed. Sustainability studies provide the necessary roadmap for these principles. The objective of sustainability is to be considerate in the usage of resources, not to deplete them and damage the environment with the products and production processes. Management attitudes incorporating these principles would facilitate the growth of humane and sustainable online learning ecosystems which would cultivate efficient learning experiences and their renewal within local, regional, and global resources.

Cover Material

There are many opportunities associated with the excavating of landfill sites. Many landfills were filled prior to large efforts in recycling and diversion tactics, which leads to many useful and valuable materials being hidden away from use. The prospect of reclaiming materials that were once buried relieves the need to use as much virgin materials for manufacturing and production processes. Organic materials that are recovered through landfill mining can be used to generate energy, or be utilized as cover material for the disposal facility. Through the removal of materials, more capacity can be generated within solid waste disposal systems, which can prolong the operating life of the facility, reduce the need to transport waste to other regions for disposal and ensure a longer period for which new landfills can be sited. Landfill mining is an option to recover valuable materials, storage capacity and generate energy but must be done where it is economically, socially and environmentally appropriate.

This article describes the advantages and challenges faced by the handmade beer producers of São Sebastião and Ilhabela regarding the use of reverse logistics in their production processes. It begins with a review of the growing demand of handmade breweries and the need to refine their logistical processes. The following is a referenced description of reverse logistics and how it has become an important competitive differential in the reduction of waste disposal in the environment and its consequent reduction in costs. Analyzing what types and to what extent production control is performed and how the use of reverse logistics is faced, through bibliographic research and case studies. For this purpose, questionnaires were carried out with handmade beer producers and it was possible to conclude which advantages and challenges can be faced by producers in the reverse logistics between them, the advantages in the reduction of costs and the aggregation of socio-environmental value, and the disadvantages such as financial unfeasibility and difficulties in obtaining packaging.

She's traditional costumes are both tangible and intangible cultural heritage, which do not only have a high aesthetic value, but also embody She's enduring beliefs and characters. However, with the economic development, social progress, especially technology updates and promotion of the traffic and media, the protective barrier of She's original cultural environment formed naturally by the geographical environment in the past have gradually disappeared. She's traditional culture, including costume culture, is rapidly weakening and lost. Based on the fieldwork of She ethnic minority areas in Zhejiang, Fujian, Jiangxi Provinces of the East China, as well as the costumes and their cultural background information, this article analyzes three aspects of She's ecological concepts shown in costumes, as "Harmony between Man and Nature" - the Understanding of Environment, "Make the best use of things" - the understanding of the finiteness of natural resources, and ¡°Survival of the Fittest¡± - the Relationship between Ecosystem and Costume. She's costumes reflect a natural living environment, as well as a mode of the production and technical status of the She people. At the meantime, they reflect the national consciousness, the religious conceptions, the social attitudes, and aesthetic tendencies state of the She people, which embody the mutual relations and interactions of natural ecosystems and human cultural ecosystem.

Treatment Procedures

My response to Fey’s article (1985; reprinted 1992, this issue) focuses on the confusion caused by the application of simplistic phonological definitions and models to the assessment and treatment of children with speech delays. In addition to having no explanatory adequacy, such definitions/models lead either to assessment and treatment procedures that are similarly focused or to procedures that have no clear logical ties to the models with which they supposedly are linked. Narrowly focused models and definitions also usually include no mention of speech production processes. Bemoaning this state of affairs, I attempt to show why it is important for clinicians to embrace broad-based models of phonological disorders that have some explanatory value. Such models are consistent with assessment procedures that are comprehensive in nature and treatment procedures that focus on linguistic, as well as motoric, aspects of speech.
