Processing Porous and Non-Porous Surfaces

Part One

For this assignment, you will process a variety of porous and nonporous items for latent prints using black fingerprint powder or crushed charcoal. Choose between 5–10 different types of surfaces (porous and nonporous). It is very important to pick a variety of different surfaces for this Assignment. Some types of surfaces that you would expect to find fingerprints on include: Microwave, Oven Door knob, window, sliding-glass door Bathroom mirror, toilet seat, Paper items around the house (at least two) Cars Soda cans Bowls and dishes, glasses, etc.

Describe your experience in a 300–500-word essay, addressing the following questions: How many different prints or partial prints did you locate? What types of objects did you lift the prints from? Where were they located? What supplies did you use? What technique did you use to apply the powder? Did you expect to find more prints, or fewer? Can you identify the prints as different from one another? How? Identify which items are porous, and which are non-porous.

Provide as many details about your successes and failures as you can.

Part Two

In this part of the assignment you will determine the effects of water on latent prints. Take a drinking glass and handle it, making sure to leave fingerprint impressions on it. Immerse the glass in water for several hours. After a significant length of time, visually examine the glass and see if you can still see your fingerprints. Attempt this in a variety of conditions such as hot water, cold water, soapy water, or salt water. Keep notes on your results under each condition. Hypothesize reasons for similar and dissimilar results under the varying conditions.

Describe your experience in a 300-500-word essay and discuss your results from this experiment. INCLUDE PHOTOS OF YOUR WORK TO MAXIMIZE YOUR POINTS.

The planning for the community building session is almost complete. The last details are how to conduct the plenary sessions for sharing information across groups to develop key priorities and themes that will need to be addressed.

There are two sessions that need to be planned. One is to review the work done by intact work teams. In this larger session, the goal is to spot patterns and identify themes that can be used to plan actions. These patterns or themes will come from the stopcontinuestart charts developed by each functional group. In this way, not only will the changes that need to happen be identified, but aspects of effective work (those things that work well and should be continued) can also be reinforced.

The external consulting team strongly recommended a “cross-functional, by-level grouping” for the first step. Their aim is to promote understanding of priorities and show how different issues at different levels of the organization can be aligned. The internal consulting team is excited about being the primary facilitators for these sessions. Everyone recognizes that a structured approach will be critical (for timing and to control decisionmaking inputs). The approach called Nominal Group Technique (NGT) seems to be ideally suited to this task.

You want to prepare yourself for conducting the session. Use the library, Internet, or other resources to research NGT. Because each grouping will be of a differing size, you want to tailor the overall steps of NGT to the situation you will facilitate. To do this, you must create a meeting session plan (a document of 45 pages) that will answer the following questions:

    What is the goal of the session?

    How will the nominal group technique be used to achieve this
    goal?

    How will the members of the team work together (guidelines for
    effective participation)?

    What specific steps and tasks will be involved in achieving the
    goal?

    How much time will be allocated to each step or task? What
    voting mechanism is most appropriate for the size of the group
    and the specific stage of the process?

    What will the outcome look like? What will the group present to
    the other levels?
