A high and sustainable quality of life is a central goal for humanity. Our current socio-ecological regime and its set of interconnected worldviews, institutions, and technologies all support the goal of unlimited growth of material production and consumption as a proxy for quality of life. However, abundant evidence shows that, beyond a certain threshold, further material growth no longer significantly contributes to improvement in quality of life. Not only does further material growth not meet humanity's central goal, there is mounting evidence that it creates significant roadblocks to sustainability through increasing resource constraints (i.e., peak oil, water limitations) and sink constraints (i.e., climate disruption). Overcoming these roadblocks and creating a sustainable and desirable future will require an integrated, systems level redesign of our socio-ecological regime focused explicitly and directly on the goal of sustainable quality of life rather than the proxy of unlimited material growth. This transition, like all cultural transitions, will occur through an evolutionary process, but one that we, to a certain extent, can control and direct. We suggest an integrated set of worldviews, institutions, and technologies to stimulate and seed this evolutionary redesign of the current socio-ecological regime to achieve global sustainability.cultural adaptation ͉ ecology ͉ societal decline T he history of human-dominated socio-ecological systems is one of successive climbs to regional prominence followed by crises that were either successfully addressed, leading to sustainability, or not, leading to decline. Historical research demonstrates that crises leading to a society's decline do not result from a single, easily identifiable cause with easily identifiable solutions (1-4). They usually result from the human-dominated ecosystem moving to a brittle, nonresilient state caused by internal changes or external forcings (2,5,6).For example, the earth's climate has gone through natural and often abrupt variations, creating new conditions, persistent for decades and centuries, that were unfamiliar to the inhabitants of the time (5). Dramatic effects and societal decline, however, occur only when socioecological systems have become brittle and unable to adapt due to other causes (1-4), including deforestation and habitat destruction, soil degradation (erosion, salinization, and soil fertility losses), water management problems, overhunting, overfishing, effects of invasive alien species, human population growth, and increased per capita impact of people. Some ancient civilizations that were not able to adapt to climate change, leading to their demise, include:Y The Akkadian empire of Mesopotamia, where a shift to more arid conditions contributed to abrupt collapse about 6,180 years ago (7). Y Parts of low-latitude northeastern Africa and southwestern Asia, where severe drought caused major disruption about 4,300 years ago (8). Y The Tiwanaku civilization of the central Andes, where a prolonged period of drought...

Communication is born as a response of the human being to interact with other people in companies to motivate human resource and obtain the expected results and work with the best workers in an increasingly competitive market; internal communication plays an important role in improving the working environment and an excellent performance of workers. The constant change brought about by world globalization, forces organizations to apply methods that organize the means to lead the company to obtain better performance and make full use of all its resources; without it, it is created an environment of instability and uncertainty among its members. Business communication can be seen as a strategic tool in relation to the organization with the environment and interaction with the staff, showing the results expected by the company analyses by empirical data. The research is developed through a descriptive and empirical methodology to identify through surveys to workers from different companies, the current problems presented by organizations in internal communication; thus establishing the consequences of poor organizational communication; finding the real problems that affect the companies of the Colombian industry and of the world, to find possible solutions.

We wholeheartedly agree with Knecht's (1) assessment and comments on our recent article (2). Current worldviews, institutions, and technologies (WITs) have created an unhealthy lifestyle for many in the developed world. Global warming, peak oil, and loss of biodiversity threaten socio-ecological systems, including food and medicine. Under the current WIT, the medical industry is as dependent on business-as-usual as any other. In the United States, health care is a for-profit industry. Insurance companies fail to fund cost-effective preventive medicine. Per capita medical expenditures in the U.S. are twice those in other wealthy nations, yet health outcomes are far worse. Reducing societal complexity could decrease the material and energy inputs available for high-cost medical care. But there are opportunities for improved health if we can mount an appropriate response in time. For example, local food systems would use far less fossil fuel inputs. Food processing, transportation, and packaging would be reduced. Diet and exercise habits would improve. Diseases related to environmental toxins would decrease. In a new WIT where prevention enjoys a much higher priority, we can overcome roadblocks to sustainable health and improve overall quality of life.

RESUMENEn la actualidad muchas pequeñas organizaciones en el siglo XXI fracasan debido a la falta de implementación de una planeación estratégica y a la inexistencia de un plan de negocios que les permita trazar las vías para alcanzar cada uno de sus objetivos y metas. Esta situación resulta bastante preocupante ya que, debido a esto son muchas las organizaciones que cesan sus actividades y ABSTRACT Actually many small businesses are currently failing in the century 21rst because of the lack of implementation of strategic planning and the lack of a business plan that allows them to chart the ways to achieve each of their goals and objectives. This situation is very worrying, because many companies cease their activities and end up going bankrupt damaging the economy and slowing down national development (century 21rst). It is for this reason that this research proposes to show the importance of the development of strategic planning in companies and the implementation of an adequate business plan that provides stability and success in their activities, reducing the risk generated by the current markets. These markets are becoming more competitive, demanding and aggressive. Only the companies that are better structured will be able to compete and grow, solidify their bases and position themselves in the markets. The research is done under the method of reflective research. This allows you to investigate real market information by providing detailed results of the current situation Barreras que dificultan la planeación estratégica en las organizaciones Fernández Hurtado _ Saúl Rick, Martínez Martínez _Luz Ángela, Ngono Fouda_ Regine Adele Palavras-Chave: competitividade, planejamento estratégico, plano de negócios, sustentabilidade, diferenciação.
