Disadvantages : Can be repetitive (boring) if there is a great deal of topical overlap as you consider each of the perspectives. Sort-by-property sequences Sort-by-property sequences are special topical sequences which allow a presenter to choose one property (or dimension) of their material and organize along that property (or dimension). You can choose any quality, as long as you can evaluate each item in your list. importance, brightness, size, speed, popularity, shape, concreteness. Once you choose the property, you then sequence your items in an appropriate order, often ascending or descending. . For example: Smallest to largest Most understood to least understood Most concrete to most abstract (specific to general) least impactful to most impactful The optimal sort order may depend on the audience and the goals of the presentation.

Disadvantages : Unlike previous patterns covered, topical patterns are not intuitive. By their nature, topical sequences are more abstract. Audiences can easily get lost, and may have difficulty seeing how the sequence items relate. Its also easy for a presenter to miss an important topic. For these reasons, a topical sequence is generally weaker than other options. Perspective-based Sequences A perspective-based sequence is a little like a topical sequence turned inside out. Instead of looking at different aspects of the main issue, a perspective-based sequence involves investigating some entity through a series of different lenses. For example, consider a proposal to adopt a corporate initiative on telecommuting. One way to sequence your presentation resume would be to consider the impact of the policy from several perspectives: From the perspective of telecommuting employees From the perspective of office-based employees From the perspective of managers From the perspective of it great from the perspective of Accounting. Audience analysis is key!
The sequence suggests simplicity which may not be real. (It suggests a black-and-white situation, even though there may be fifty shades of grey.) For example, how do you handle a factor that is diary neither a cost nor a benefit? How do you handle a factor that is both a cost and a benefit? The choices you make seriously impact your success. Topical Sequences When all else fails, you can usually apply a topical sequence. Examples of presentations where a topical sequence may apply: Presenting a project plan (budget, schedule, staffing, testing) Unveiling new corporate strategy and discussing the impact on different stakeholders (marketing, sales, manufacturing, suppliers, customers) School dress code presentation (code details, common violations, enforcement, uniform costs) Advantages : Can. Because of this, it is the most common sequence pattern.
Paired Sequences paired sequences are short — only two items — but are quite common due to our propensity to compare and contrast. There are a number of paired (or binary) sequences: Advantages. Disadvantages (Costs vs Benefits; Pros. Proposal to replace a paper-based process with an electronic one Problem. Strategy to recapture shrinking market share cause. Impact of chemical processing plant on local water supply Advantages : Natural pairings are easy to understand, and audiences expect that one will follow the other. Using a paired sequence generates anticipation and suspense. Disadvantages : The binary nature of the paired sequence may not be flexible enough to handle complex real-world topics.

It can feel like a long, tiring sequence, and may make it more difficult to highlight key takeaways. Step-by-step Sequence In a step-by-step sequence, items are organized according to their order within a process. . Examples of presentations where a step-by-step sequence may apply: How to upgrade financial management software how to stuff and cook a turkey how to change a flat tire Advantages : Easy argumentative to apply, and easy to follow. Particularly effective for any type of how to presentation. Disadvantages : None, provided that the nature of the presentation is a good match for this sequence type.
Spatial Sequence The most common type of spatial sequences in presentations are those which organize items by geography. Examples of presentations which might use a geographic sequence are: roadside attractions along the Oregon coast Ukrainian settlements throughout Canada from 1891 to 1914 Local, regional, and national impact of hosting the Olympics But spatial sequences do not always correspond to geography. Spatial sequences can also sequence the connected parts of a whole. Example presentations include: Functions of different parts of a plant (roots, stem, branches, leaves, fruit) How to design an ergonomic office/workspace (computer, desktop, seating, storage) Human nervous system (brain, spinal cord, nerves) Advantages : Emphasizes the spatial relationships between your items. This animals can lead to a stronger understanding of the whole. Audiences can easily visualize how items fit together, particularly if you provide a map, diagram, or scale model. Disadvantages : A spatial sequence is sometimes used even though the spatial dimension is meaningless to the content.
If you organize them into a single list (i.e. No sub-lists, no hierarchy then you have created a simple sequence. There are several simple sequences available to you, including: Chronological sequence, step-by-step sequence, spatial sequence. Paired sequence, topical sequence, perspective-based sequence, sort-by-property sequence. Each of these simple sequences is discussed below. Chronological Sequence, in a chronological sequence, items are ordered according to the date or time they occurred. .
Examples of presentations where a chronological sequence may apply: key events in the War of 1812. A day in the life of. Development stages during a babys first year. The past, present, and future of aviation safety. Many scientific presentations follow a loose chronological sequence to recap the steps undertaken in an experiment: Background, hypothesis, experimental methods, data, analysis and discussion, conclusions. Advantages : A chronological sequence is easy to apply. Because most stories (parables, novels, movies) follow this pattern, it is a familiar pattern for audiences, and is thus quite easy to follow. Disadvantages : Chronological sequence encourages and-then syndrome ( and then and then and then and then).

The content of summary this website must not be reproduced without permission and without"ng the source. There are many ways to organize your presentation. . The choices you make seriously impact the success of your presentation. If you order your material in an intuitive manner that your audience can readily understand, they are more likely to be persuaded. If you order your material in an awkward manner, your audience will struggle to understand, and they will resist being persuaded by your message. Given the criticality of your presentation sequence, how do you choose the right one for your topic and your audience? In this article, we: survey the available sequence types, give examples of presentations which fit each scheme, and discuss the advantages and disadvantages of each. Simple sequences, suppose you have a number of points you would like to discuss. You cant discuss them all at the same time, so you have to decide which goes first, which goes second, and which goes last.
In 2004 they both moved to the. Johann Wolfgang goethe University Frankfurt am main and since 2009 Stefan siebert is working at the. Since 1999 the methodology to produce the map has been improved which made it possible to increase the spatial resolution of the map to 5 minutes (about 10 km at the equator). The objective of the cooperation between the Universities and fao is to develop global gis coverage of areas equipped for irrigation and to make it available to users in the international community. The data collected through the aquastat surveys will be used to improve the overall quality and resolution of the information. note country-level time series on area equipped for irrigation, starting in 1961, can be found on the. Faostat website by choosing the item "Total area equipped for irrigation". Republic set of Srpska government.
United Nations and the. Rheinische Friedrich-Wilhelms-Universität in Bonn, germany, are cooperating in the development of a global irrigation mapping facility. The mandate of the food and Agriculture Organization calls for the dissemination of global information on food and agriculture. Through its Land and Water division, it maintains an information system on water and agriculture and systematically collects, analyzes and disseminates this information. The first global digital map of irrigated areas on the basis of cartographic information and fao statistics has a resolution.5 degree and was developed in 1999 by Stefan siebert and Petra döll. At the time of the development of the first version of the map they were working at the. Center for Environmental Systems Research of the University of Kassel.
They are effective in presenting information and communicating findings. Maps allow us to paper convey information and findings that are difficult to express verbally, or to condense messages that would be lengthier to describe in words. They are often more memorable, because they have colour and shape. They can be used to demonstrate relationships in a way that is more striking by showing the intensity of a problem in one area relative to the intensity in another area, or by showing the change in distribution of a resource over time. The most commonly mapped environmental information of relevance to the health sector includes: pollution sources and affected areas (including sewage, solid waste, hazardous waste, industrial pollution, smoke and other emissions, and radiation land cover and use (including vegetation type, vegetation change and condition, agriculture, forestry. Availability and sources of this information are given in detail below, under the directory of references. Mapping techniques can be used in two main ways to show the links between environment and health. Simple overlays (comparisons) of environmental and socioeconomic (health) data can be used to identify patterns, which can then be investigated later for correlations, as in the example shown in Figure. Once the causal relationship is known, however, spatial models can also be developed to predict (in this case) changes in health based on environmental changes.

This policy brief relates to the use of plan spatial representation of environmental information, and how such techniques can support the integrated analysis of health and environment data, as well as presentation of summary information. This paper reviews the strengths and weaknesses of maps and mapping techniques, provides some key illustrations and case studies, and lists some of the major information sources. Maps and spatial information technologies have three main advantages: They can be a means of recording and storing information. Governments, the private sector, development agencies, and civil society groups store large quantities of information about the environment and the location of natural resources, as well as about populations and demographic trends. They can be used to identify and investigate spatial patterns. Maps draw attention to spatial relationships, for example the distribution of a resource over space, over time, or in relation to other factors such as the presence or growth of human settlements. Once these relationships are recognized, we can start to analyse them and search for the underlying causes and processes, which in turn can be useful in improving planning and development.
