5. From Corrosion to Collapse: The Destruction of Native Communities

Nicholas A. Robins Indiana University Press ePub

“Neither Livestock nor Lands nor Houses”: A Horrific Homecoming1

The mita, mercury, and silicosis did not just kill and maim individuals, they also did the same to countless indigenous communities throughout the altiplano and valleys as their effects reverberated throughout the region. As a key element in the colonial exploitative equation, the mita exacerbated both the ongoing abuses against Indians by their overlords as well as divisions among the elite as they competed for Indian labor. Further complicating the situation were the myriad physical and mental effects of quicksilver and silicosis previously described. In addition, while Potosí was for many years the most important mining town in the Andes, silver production and mercury pollution occurred throughout the region on both small and large scales. As a result, both free and forced laborers, mine owners, colonial officials, clergymen, artisans, and anyone or anything else in these areas that breathed were at a high risk of being poisoned. Governors, priests, officials, and commoners did not stay in one place but often moved as they sought better lives or purchased new jurisdictions, positions, and parishes. The result was that the human effects of mercury and silver production were by no means limited to Huancavelica, Potosí, and other mining centers, and those who were poisoned became carriers who imported their afflictions to towns and cities that did not produce silver or mercury. Such was the profoundly exploitative nature of colonial society, however, that mercury only exacerbated entrenched practices and abuses. Examining what natives had to contend with in their villages rounds out the picture of what awaited them if they returned home from the mita, and underscores the broader, regional effects of the amalgamation economy.

Pareto Analysis

Description

Pareto Analysis is a process that graphically shows the relative importance of a small number of factors. It helps to focus attention on the “vital few” factors as opposed to the “trivial many.”

Situations

In many problem-solving processes, there are a number of potential causes, situations where the problem occurs, or solutions to a problem. Pareto Analysis can be used to identify the cause, situation, or idea that has the greatest impact.

Objectives

Y

To identify the one or two situations where most problems occur

To identify the one or two causes to a particular problem

To identify the one or two ideas from which the greatest benefit will be achieved

Trainer Guidance

The process is named after Count Vilfredo Pareto, an Italian economist who was studying the Italian economy and identified that about 80 percent of the wealth of the country was held by only 20 percent of the population. This 80/20 rule is the key to Pareto Analysis.

This principle—accounted for by just a few reasons—can be applied to a wide range of situations:

16 Dewdrop Flowers

Dewdrop Flowers

Reproducing nature scenes in the studio

Capturing extreme magnifications

Optimizing depth of field using focus-stacking techniques

I like images in which colorful objects are magnified by dewdrops (that serve as tiny lenses), so I decided to produce the effect in my studio. I began by checking on Flickr to see what other photographers have done and found the photostream and tutorials of Brian Valentine (his alias is Lord V) at www.flickr.com/photos/lordv. Brian is obviously more of a nature fan than I am because he shoots outdoors, but he uses the same off-camera flash approach as described in this workshop.

Brian’s tutorial sounded easy, but my attempt took a lot longer than I anticipated. The first major hurdle was creating dewdrops on the blade of grass. An eyedropper didn’t work because the drops simply rolled off. I finally produced effective drops by filling a perfume atomizer with water and spraying it on the grass. After I created a row of drops, I removed excess water by carefully dabbing it with the corner of a paper towel.

Take Time to “Journal”

Lois Hart HRD Press, Inc. PDF

Take Time to “Journal”

Trainer’s Notes for Activity 7

Step-by-Step Procedure

Step 1: Introduce the subject of journaling and provide an overview of the activity.

For a long time, professionals in some disciplines have used journaling as an active recall process. Those in the acting/directing profession are especially devoted to this technique. New actors are encouraged to write their ideas and feelings (free-flow) for at least

20 minutes a day. They thus develop a personal journal that captures an array of moods and emotions that can later be drawn on as they prepare for different character roles.

As a leader, you are not really playing a character, but you are, in a real sense, orchestrating the team to work together to solve a business need or problem. A journal provides a personal and private way to track your great moments. If you use it regularly, you will capture your greatest successes, but – most importantly – you will also be recording those times when your choices weren’t the best. New strategies and tactics can later be deduced from those writings.

2. How to Build It: Lean Prototyping Techniques for Hardware

Thomas Eisenmann O'Reilly Media ePub

After recently writing a blog post on my vision for the future of 3D printers, I wanted to expand more broadly on my thoughts on prototyping technologies, and particularly on rapid and lean prototyping for mechanical designs.

“Lean” started in the context of manufacturing automobiles, and has since been taken to describe prototyping and customer development for software startups. Many software/web startups do not win because of a science or technology invention. Instead, user experiences and marketing are what drive success. I think people are realizing that this can apply to hardware as well, and the increasing ease of prototyping is helping to drive the increase in hardware-based projects and startups such as those seen on the design section of the crowd-funding platform Kickstarter. Of course, hardware continues to have the challenge that production and distribution continue to be more difficult than for software.

I will outline here the tools and methods I use in prototyping hardware.
