Composting eats away at Indonesia's trash problem
Nov. 26 - The Indonesian city of Surabaya has taken composting to new levels in a so far successful effort to reduce its considerable garbage problem. With rubbish piling up all over the city, a composting program was launched more than ten years ago and today, the results speak for themselves. Tara Cleary reports.
Green toilet saves water, feeds garden
Nov. 21 - In the western world, thousands of gallons of water are flushed down the toilet every year - valuable water that could otherwise be used for drinking or growing food. But a Canadian company is trying to minimize that waste by producing waterless, composting lavatories that not only save water, but also producer fertilizer for the garden. Tara Cleary reports.
2.7 Inferring relationships of common ancestry This clip addresses the question of how one might go about building a tree, or inferring relationships of common ancestry, by recognising evolutionary novelties, or share Introduction This unit provides an overview of the processes involved in developing models. It starts by explaining how to specify the purpose of the model and moves on to look at aspects involved in creating models, such as simplifying problems, choosing variables and parameters, formulating relationships and finding solutions. You will also look at interpreting results and evaluating models. This unit, the third in a series of five, builds on the ideas introduced and developed in Modelling poll 1.1 Mathematics and you Many people's ideas about what mathematics actually is are based upon their early experiences at school. The first two activities aim to help you recall formative experiences from childhood. Read 1.2 Squaring fractions and negative numbers You have now seen how to find squares of whole numbers and decimals. What about fractions? The rule is as before: to square a fraction, just multiply it by itself. For example: In Example 1, you could have used Author(s): 1.2.1 Heating and cooling the Earth: the overall radiation balance The Sun emits electromagnetic radiation with a range of wavelengths, but its peak emission is in the visible band – the sunlight that allows us to see. The wavelength of radiation has important climatic implications, as we shall see shortly. For now, we are mainly interested in the overall rate at which energy in the form of solar radiation reaches the Earth. Introduction Sweatshops and the exploitation of workers are often linked to the globalised production of ‘big brand’ labels. This unit examines how campaigners have successfully closed the distance between the brands and the sweatshops, while others argue that such production ‘kick starts’ economies into growth benefiting whole communities. This unit is an adapted extract from the Open University course Author(s): 2.4 Summarising conversation as what matters Brian Wynne suggests that fundamental dichotomies associated with environmental matters underpin modern society – society versus nature, the social versus the natural, social knowledge versus natural knowledge, expert knowledge versus lay knowledge (1996, p. 45). The metaphor of conversation helps to move us beyond these dichotomous constructs and allows us to focus more on the integral relationships enmeshed in nature matters, relationships that I would argue are central to environmental r 2.1 Environment and technology A central concern of environmental studies is the relationship between technology and our environment: how people use technology to transform materials into forms which can meet our needs and wants. In the process of doing this we inevitably change the environment which provides these materials but which also supports all life. A few moments ago I went to my fridge and took some milk out to add to a cup of coffee. I used this common example of a modern domestic appliance without a secon 1 Introductory advice There are two ways to approach this Introduction. The first is the more natural one: to read it straight through to get a general feel for its style and content, and to see whether you are going to find the unit and the issues it raises interesting; in short, to get an overview. There is nothing wrong with this at all. You will find as you read through it, though, that the Introduction covers a wide range of topics. In part this is because the unit authors takes a broad vi Learning outcomes When you have completed this unit you should have: developed an awareness of different ways in which our use of technology can affect the environment developed your own skills in reading and interpreting texts and diagrams containing some technical descriptions 6.5 Military and humanitarian interventionism While the ICC may be the most radical cosmopolitan effort at global justice institution-building so far, it is not the only one. The move towards cosmopolitan global institutions that extend beyond the UN's original goals and values has speeded up during the 1990s. Cosmopolitans would contend that international institution-building does not necessarily lead to more interventionism. Communitarians such as Chandler see as significant that in the field of international human rights interventioni 6.2 Some general features of communitarianism and cosmopolitanism There are two very different and sharply contrasting views about how the international arena can be theorised, should be organised and can be described. One side sees the international sphere as made up of a plurality of interacting cultures with incommensurable values, while the other side deploys general concepts of rights and applies these to humanity as a whole. These two constructions rest upon very different views of what human beings are, and how they do and should interact together. 6.1 Introduction The international level can be viewed as an arena of politics in its own right and not just as a context for states and other actors. If we think of the international world in this way, how should relations between states, and other actors on the international stage, be constructed? To what extent should those relations be regulated? We can ask whether relations between states, and states' policy making, should be dictated by allegedly universally shared human rights principles, or by other o 5.2 Human rights in the international arena The UN's 1948 Universal Declaration of Human Rights asserted that the ‘recognition of the inherent dignity and of the equal and inalienable rights of all members of the human family is the foundation of freedom, justice and peace in the world’. It further affirmed that human rights should be protected by the rule of law, that they were ‘essential to promote the development of friendly relations between nations’, that these fundamental human rights include the equal rights between men 1.4 Offshore fragments of industry: the negative standpoint Nike Inc., the US sportswear firm, did in fact take the lead in organising its overseas manufacturing business on a subcontracting basis (Donaghu and Barff, 1990). Early on in the 1970s, it established a web of contractual relationships (or partnerships, as it preferred to call them), with factories in Taiwan and South Korea, to produce its branded footwear. Of these factories, the big-volume producers among them were also contracted to other Western firms to produce a range of footwear. Nike 2.3.1 Structural isomerism In the saturated hydrocarbons, whose structural formulae are shown in Figure 16, it is not possible to form distinct isomers with just three or less carbon atoms linked together. There is only one way in which one carbon and four hydrogen atoms can be linked together, the single compound being methane, CH4. A simila
