The Capper-Volstead Act, 42 Stat. 388 (7 U.SC. §291) ("C-V" or "Capper-Volstead") was passed in 1922. Some 90 years later farmers and their cooperatives continue to rely on the limited antitrust protection provided by C-V and other Acts passed around that time. The pertinent wording of C-V is as follows:
Persons engaged in the production of agricultural products as farmers, planters, ranchmen, dairymen, nut or fruit growers may act together in associations, corporate or otherwise, with or without capital stock, in collectively processing, preparing for market, handling, and marketing in interstate and foreign commerce, such products of persons so engaged. Such associations may have marketing agencies in common; and such associations and their members may make the necessary contracts and agreements to effect such purposes: Provided, however, that such associations are operated for the mutual benefit of the members thereof, as such producers, and confirm to one or both of the following requirements:….
Some argue today that because farms have grown much larger and some have vertically integrated and because cooperatives have grown larger and have become vertically integrated, they should no longer be able to rely on C-V, but should be governed by the same antitrust rules that apply to other businesses.
I respectfully disagree with those who want to restrict or eliminate C-V antitrust immunity for agricultural cooperatives. My view is that the C-V immunity is if anything even more critical to farmers today than when enacted in 1922. This article explains why there is an increased reliance by farmers and their cooperatives on C-V today.
My personal story will illustrate the growth of farms. I grew up on a dairy farm in southeastern Idaho during the 1940's and 50's. My family farmed about 100 acres where we grew hay, barley and silage corn to feed our herd of 25 milking cows and the accompanying dry cows, heifers and calves. There were several smaller dairies in our town and a few larger. It seemed like a lot of hard work to milk the cows twice a day, feed them, clean the barn and care for the equipment, and still do the other farm work. We had to do the first milking and the morning chores in time for me to clean up, have breakfast and catch the bus at 7:55 while school was in session.
Initially, we sold our milk to a proprietary condensed milk company some 15 miles away. However, we were not able to benefit from higher prices obtained by other dairymen who had access to the fluid milk plants in Salt Lake City, over 100 miles away. Then my Dad sought and obtained membership in a dairy cooperative which owned a fluid milk processing plant that served much of Utah. Membership in this cooperative enabled us to get a better price. The higher price and resulting increased revenues enabled us to upgrade our barn and facilities. Over time we also grew our herd to around 100 cows. Nevertheless, despite the success and (for the time) relatively substantial size of our family's dairy farm, even then we were wholly reliant on the dairy cooperative to provide us a market.
When we could find no land to buy which would allow us to grow the dairy operation sufficiently for me to stay and earn a living on the farm, I decided to follow in the footsteps of an uncle into the legal profession.
Now as I visit my home county in southeastern Idaho I find about the same population of people, but a greatly increased population of dairy cows. In fact, I recently visited a dairy with over 3,000 cows only a few miles from our farm, which we have since sold to a neighbor so that he could expand his dairy. I found that this 3,000 cow dairy is wholly reliant on its cooperative for a market, just as my family's farm had been. If the cooperative did not pick up the milk every day, process it, market it and pay for it, this 3,000 cow dairy could not last a month.
Dairymen do not have direct access to markets because they cannot afford to do their own processing and marketing. They must rely on their cooperatives or proprietary handlers. On my family's farm, we soon found that the proprietary handlers would cut back on what you could ship if their market shrank, but that the cooperative would take all our milk every day and would put the excess supply into butter, powder or cheese to help balance supply of fresh milk to demand.
My experience on my family's farm showed me, as confirmed years later by the experience of a 3,000 cow dairy farm in my home county and by many similar experiences, that without dairy cooperatives today we would have a vastly different and far more concentrated dairy industry. Cooperatives are critical to the economics of dairy farms. Since C-V is critical to the existence of dairy cooperatives, C-V immunity is critical to the economics of dairy farms. Similar economics in other agricultural sectors lead to the same conclusions about the need for farmers and ranchers in those sectors to rely on agricultural cooperatives to provide a market, and thus on the continuing need for C-V immunity to allow cooperatives to exist.
Dairy farmers in my view have become even more reliant on cooperatives to provide a market for their output, and cooperatives have had to grow accordingly, because of the massive growth of retailers and middlemen. While dairies were becoming fewer and larger we have seen the grocers, food service and other wholesale customers grow much more than the dairies. Today, a 3,000 cow dairy has no better chance to market its milk than we had with our small dairy 50 years ago. Our cooperative has had to also grow through mergers and acquisitions in order to meet the demands of today's giant customers such as Kroger, Wal-Mart, Costco, Associated Foods, and others.

Solubility - 2656 Words
Solubility and Functional Groups _______________________________________________________ You will recall from general chemistry that a solution has two components: the solvent, which is the substance present in greater amount, and the solute, which is dissolved in the solvent. Solubility is defined as the mass (in grams) of solute dissolved in 100 g of solute at saturation. Molar solubility is defined as the amount (in moles) of solute per liter of saturated solution. The solubility of one...

A supersaturated solution is a solution that contains more dissolved substance than a saturated solution does. This occurs when a solution is prepared at a higher temperature and is then slowly cooled. This is a very unstable situation, so any disturbance causes precipitation. Solubility can be understood in terms of two factors: The natural tendency toward disorder favors dissolving. The relative forces between and within species must be considered. Stronger forces within solute...

factors affecting solubility 1. Effect of Temperature For some substances to dissolve in a given solvent, heat is absorbed. The reaction is endothermic. In this case, an increase in temperature increases solubility. For some substances, heat is released when they dissolve in a given solvent. The reaction is called exothermic. In this case, an increase in temperature decreases solubility. Generally, an increase in temperature in the solubility of solids in liquids increases solubility. But for...

Solubility and Spectator Ions - 557 Words
Precipitates are electrically uncharged. In this experiment all of the precipitates result from the exchange of positive and negative ions between reacting solutions of two ionic compounds. Thus, in this example the precipitate must be either silver chloride, AgCl or sodium nitrate, NaNO3. Sodium nitrate dissolves readily in water and is therefore soluble. Thus we can conclude that silver chloride is the insoluble precipitate. We can represent the formation of this precipitate by a net ionic...

When ionic solids dissolve, they divide to give their positive and negative ions that make up the solids. These ions become hydrates and have the same relative proportions when in solution and when solid. The more the solid dissolves, the more the ion's concentration increases. This increase and build-up allows for the reverse reaction to occur. In this phase of the reaction the ions crystallise out in order for the reaction to have a greater chance of occurring.

recrystallization - 1242 Words
Recrystallization is the most common method for purifying an organic solid. This technique relies on the fact that the solubility of an organic compound often increases greatly as the solvent is heated to boiling point. When an impure solid is heated in the appropriate solvent to dissolve it, then cooled down to decrease its solubility, it will usually crystallize in a more pure form. Ideal solvent is the one that your solid is insoluble at room temperature, but soluble in hot solvent ( at...

Mixture separation Lab I am one of the chemists assigned to design a cost effective procedure for handling the CARBOSE separation and recovery and hazardous waste disposal. The difficulties were trying to figure out is how we can effectively separate Carbose, sand, and naphthalene? The hypothesis we chose to solve this problem was if we put the mixture into water, alcohol, and mineral spirts, then in each solution one or more substance will not dissolve, will be visible, and also able to...

Pay no attention to the dirt, junk, mess, etc. in the background of any of these pictures.
It has been a hectic Christmas season...well the whole year has been crazy.
As told by the candy canes themselves.
So, here we are, we have been abandoned. You bought us all shiny and new at your local discount store.
You brought us home, so proudly displayed us in your yard.
We were shiny.
We lined your walkway and held up little lights.
You got tired of us, we didn't shine any longer,
we even FROZE in the ground and some of us broke!
And then...
You sold us at a yard sale!
or donated us to Goodwill..
or the even worse fate...
But thanks to some enterprising, kind-hearted crafters,
we have been saved.
They take this nice, warm cotton fabric and wrap us up nice and cozy.
The glue gun hurts a little,
The glue gun hurts a little,
But then we get decorated with some lovely reds and greens.
They seal up our ends.
But then a nice cozy wrap.
Spinning, spinning, spinning.
ready to be decorated.
At this point some of the lovely crafters give us a nice shower of coffee and vanilla.
At this point some of the lovely crafters give us a nice shower of coffee and vanilla.
Yum, it is delicious.
Some ripped homespun.
A little more glue.

Yes, the hard leap for many to get their head around is that your cell phone, TV and Internet connection are vital "Critical Infrastructure" and if you are a Verizon, AT&T, Sprint or large cable company in the United States; national security is a top of mind issue. Is it possible that our country is at risk because of the same "Risk Management" paradigm that has plagued the Financial Services industry? A lack of resources and focus to detect, deter, defend and document risks to critical infrastructure could turn into a systemic and interdependent threat to our national security.
How can you make the case for the economic meltdown in the financial services sector to be similar to the potential failure of the communications, IT, water or energy sector? It's easy. Look at human behavior and to the motivators of greed, selfishness and just plain blindness to a "risk bubble" just waiting to burst. Who will be the next Bear Stearns in the communications sector? The fact is that a marketing department may have a larger budget than the internal audit department and the security department combined. When the nuts and bolts, concrete and plumbing associated with electronic commerce, banking, and just plain office automation come to a slow crawl or halt in it's tracks the government will have to do the same thing all over again. Bail out the industry and the companies who are the lifeblood of our critical infrastructure.
Our national security is at stake and the owners and operators are still waiting for the right incentives to invest in robust maintenance and security programs, instead of more marketing. After all, market share is what shareholders ask about along with how many new subscribers you won or lost last quarter. How often do we hear the question at the shareholders meeting that asks about the amount of downtime, failed systems or customers without service as a result of a "Glitch" or fried circuit board?
So how does the electronic critical infrastructure really impact national security? Homeland Security Presidential Directive 7 gives us some insight:
1. This directive establishes a national policy for Federal departments and agencies to identify and prioritize United States critical infrastructure and key resources and to protect them from terrorist attacks.
2. Terrorists (including Cyber) seek to destroy, incapacitate, or exploit critical infrastructure and key resources across the United States to threaten national security, cause mass casualties, weaken our economy, and damage public morale and confidence.
3. America's open and technologically complex society includes a wide array of critical infrastructure and key resources that are potential terrorist targets. The majority of these are owned and operated by the private sector and State or local governments. These critical infrastructures and key resources are both physical and cyber-based and span all sectors of the economy.
4. Critical infrastructure and key resources provide the essential services that underpin American society. The Nation possesses numerous key resources, whose exploitation or destruction by terrorists could cause catastrophic health effects or mass casualties comparable to those from the use of a weapon of mass destruction, or could profoundly affect our national prestige and morale. In addition, there is critical infrastructure so vital that its incapacitation, exploitation, or destruction, through terrorist attack, could have a debilitating effect on security and economic well-being.
5. While it is not possible to protect or eliminate the vulnerability of all critical infrastructure and key resources throughout the country, strategic improvements in security can make it more difficult for attacks to succeed and can lessen the impact of attacks that may occur. In addition to strategic security enhancements, tactical security improvements can be rapidly implemented to deter, mitigate, or neutralize potential attacks.
A culture of risk management is slowly moving it's way into the Board Room conversations and the CEO may be on notice if the "Tone at the Top" is not focused on risk mitigation. However, that "Tone at the Top" needs to go beyond the shareholder value conversation to the national security topic. One only has to review what is happening in Brazil to get any sense of what may be heading to North America. The Toronto Sun reports:
SAO PAULO — Brazil's president says last week's massive blackouts in Latin America's largest nation were caused by a short-circuit in a transmission tower. But President Luiz Inacio Lula da Silva says it's unclear how the short-circuit happened.
The outages left nearly a third of Brazil's 190 million citizens in the dark — raising concerns about energy security for football's 2014 World Cup in Brazil, and the 2016 Olympic games in Rio de Janeiro.
Silva said Monday on his weekly radio program that the short-circuit happened in the rural Sao Paulo state town of Itabera. He says an investigation will determine why but offered no prediction on when it will be concluded.
Silva also says he will work hard to make sure similar blackouts don't happen again.
One only has to look further in a few places on the "Net" to get some idea of what the offensive cyberwarfare conversation is all about. Once you understand that the Brazil incidents are just a test, then you realize that US shovel ready projects need a new public service announcement (PSA) with a shock value of texting while driving. The risk of a specific kind of behavior on the road or within the corporate enterprise can have the same results. We have already nationalized the likes of AIG, Freddie Mac and Fannie Mae. Perhaps it time to do the same for Cisco, Verizon, AT&T and others who are vital to national security and have them report to the Pentagon.

LONDON -- Aly Raisman has fought back tears before. You don't become an elite gymnast without shedding a few along the way. But never before had she had to hold it together, afraid she might burst into tears of unencumbered joy. After nailing her final tumbling pass on the floor Tuesday afternoon, though, the emotions were written all over her face, even before she hit her final dismount pose. She put a hand up to her mouth and the tears began welling. Having seen the Russian team falter on the floor before teammates Gabby Douglas and Jordyn Wieber nailed their exercises, she had to know a relatively clean routine would seal gold for the U.S.
"I was just hoping that we had won," she said. "I hadn't been keeping track of the scores, but I was just so proud of all these girls.... I just wanted to finish up on a strong note for Team USA."
In a whirlwind two days, the 18-year-old native of Needham, Mass., has catapulted herself into the spotlight in London, earning the top U.S. score in qualification Sunday and then clinching the team win with the day's best floor routine Tuesday. The team win capped off a couple days of mixed emotions for her, though. Her strong performance on Sunday, coupled with Douglas' rise in the all-around in recent weeks, meant Wieber, her friend and roommate here in London, would not qualify for the all-around because of the rule that only two gymnasts can represent their country in the individual event.
But there were no mixed emotions Tuesday. With a gold medal around her neck and surrounded by her teammates on the podium at North Greenwich Arena, Raisman had achieved something she has spent almost a lifetime dreaming about. Soon after she could walk, Raisman could tumble. Her mother, Lynn, took her to a Mommy and Me gymnastics class when Aly was just 18 months old. Some little girls watch their favorite movie day after day, learning lines to a point where they can recite entire scenes verbatim. Growing up, Raisman chose to relive two weeks in 1996 daily. For years, she'd pop in an old VHS tape and watch the Olympic gymnastics competition in Atlanta. She marveled at the Magnificent Seven and all-around champion Lilia Podkopayeva of the Ukraine. She says she watched the tape so many times that she could recite Podkopayeva's floor routine by memory at one point.
On Thursday, she will compete in the all-around, with hopes of realizing a dream that seemed far off just a few months ago. Last March, when she finished two-tenths of a point behind Wieber, Raisman was genuinely ecstatic. "It's the closest I've ever gotten to [Jordyn]," she said, beaming. But after Douglas placed second at nationals and then won Olympic Trials, it seemed likely that Raisman might be the odd girl out in London. Instead, she'll be in the spotlight Thursday, though she may have to share it with her parents. NBC cameras captured Lynn and her husband, Ricky, watching Aly's uneven bar routine Sunday afternoon. Fidgeting in their seats and as nervous and squeamish as a seated pair could possibly be, the couple became the viral hit of the first days of the Games. That
The whereabouts of the old VHS tape, on the other hand, are unknown. It may be buried somewhere in a box of mementos in the Raismans' attic; it may have even found its way into the trash at some point over the years. No one quite knows where it's gone. But at this point, the tape itself wouldn't matter very much. It's probably so worn from daily playbacks that black bands would infiltrate the screen, so worn that the picture would probably stretch and the audio jump, interrupting Shannon Miller's beam exercise or maybe even Kerri Strug's infamous vault. It's not so much about the tape as what it came to mean to a young Raisman.
Sixteen years after the U.S. last captured gold in women's gymnastics, it might be these Fabulous Five, led by team captain Raisman, who inspire a new generation. Here's hoping that DVRs around America are recording.
