Amphibians: Bufo alvarius, also known as Colorado river toad. The Colorado river toad is found in the northern part of Mexico, the southern parts of Arizona and New Mexico, and the southeast corner of California (Robinson, 2001). The Colorado river toad is a dark olive green color and leathery skin. The Colorado river toad is carnivorous and is known to eat snails, beetles, spiders, grasshoppers, lizards, mice and other smaller toad species. Pseudacris crucifer, also known as spring peeper. The spring peeper is native to eastern North American. It is found from southeast Manitoba east of the Atlantic Ocean, and south eastern Texas and mainland Florida, but not on the Florida Peninsula (Skelly, 1996). Spring peepers are found in marshy woods and non-wooded lowlands near ponds and swamps. Although they are good climbers, spring peepers seem to prefer to be on the ground or hiding in leaf litter. This frog is usually some shade of brown, gray, or olive, and occasionally may be yellow or reddish. The spring peeper mainly eats small insects, including ants, beetles, flies and spiders. One way the Colorado river toad and the spring peeper are alike is their diet. They both eat beetles and spiders. Also they are both aquatic. One of the ways that they are different is their sizes. The Colorado river toad is a large from ranging from 110-187 mm, where as the spring peeper is a smaller toad ranging from 20-25 mm. Another way that these two are different is their lifespan. The Colorado river toad lifespan ranges between 5-15 years, and the spring peeper lifespan is 3-4 years. Both the Colorado river toad and the spring peeper belong to the Anura order. Within this order, there are twenty-five families, which represent more than 4,000 species, and more are being discovered regularly (Heying, n.d.). Anurans represent by far the most speciose, diverse, and widespread of the three extant amphibian orders. This order is found throughout most of the world.

Arthropods: Euripides Marcellus, also known as zebra swallowtail and they are found throughout the eastern United States; however they are abundantly found in the southeast (Tveten and Tvente, 1996). The zebra swallowtail prefers corridors of wooded land alongside bodies of water. They are called swallowtails because they have long tails on their hind wings, which is thought to look a bit like the long, pointed tails of the swallow birds, and they have a wingspan of 5-9 cm. The first meal that the zebra swallowtail has is its own eggshell. The zebra swallowtail also drinks the sweet nectar of flowers. However, unlike most butterflies, they are also able to collect pollen from some flowers. They digest the pollen, and absorb its amino acids. This extra nutrition lets them survive, mate and lay eggs for long periods of time (Enchanted learning, n.d.). The lifespan of the zebra swallowtail is about six months. Limenitis Arthemis, also known as White Admiral and they are found throughout the eastern United States and West into the Rocky Mountains. The white admiral inhabits deciduous broad leaf forests and mixed evergreen forest. The white admiral diet includes cherries, poplar, aspens, and black oaks. The white admiral has a wingspan of 60-70 millimeters. The life span of the white admiral is about 6 months (Parenti, 1972). The differences between the swallowtail and admiral are their size, and the fact that the swallowtails are able to collect pollen, and the admiral cannot. The similarities between the two are that they both have a lifespan around 6 months, and they both can be found in the eastern part of the United States. The order that these two butterflies belong to is Lepidoptera. The white admiral and zebra swallowtail belongs to this order because they have an antenna, compound eyes, three pairs of legs, a hard exoskeleton, and a body that is divided into three parts: the head, thorax, and the abdomen. Uniquely, a butterfly's outer body is covered by tiny sensory hairs and the wings are covered by scales.
Bony Fish: Actinopterygiians, also known as Ray-Finned fish, are a highly diverse group of aquatic vertebrates. Over half of all living vertebrate species, aquatic and terrestrial combined, are ray-finned fish. The ray-finned fish has a bony skeleton, upper jaw that consists of two bones, and fines with bony spines. The ray-finned fish inhabits such places as the deep sea, caves, turbulent rivers, and high altitude lakes. The ray-finned fish can be found in the Amazon River, and the wetlands of Southeast Asia. The ray-finned fish are herbivores, carnivores, omnivores, zooplanktivores and detrivores. The ray-finned fish belongs to the acipenseriformes order. This group is a small order of fish that includes about 25 species in two families. This is an ancient fish lineage, dating to before the age of dinosaurs. Gadus morhua, also known as Atlantic cod, and can be found along the eastern and northern coasts of North American, along the coasts of Greenland, and from the Bay of Biscay north to the Arctic Ocean, including the Atlantic waters around Iceland, the North Sea and the Barents Sea. The Atlantic cod is best described as opportunistic because they feed on anything they are capable of capturing. The Atlantic cod belongs to the Gadiformes order. The cod group is a large group of mostly marine fish, although there are some freshwater members. There are 475 species in 10 families found throughout the oceans of the world, and many freshwater ecosystems. The similarities between the Atlantic cod and ray-fined fish are that they are both migratory and dominant in their hierarchy. One of the differences between the two is their lifespan. The Atlantic cod lifespan is in excess of 20 years, and the Ray-fined fish lifespan on an average is about 25 years; however there are occasion when they can live between 80-150 years.
Mollusks:
Alasmidonta viridis, also known as the slipper shell mussel. The slipper shell is found in the upper Mississippi drainage, and in the Ohio Cumberland and Tennessee River. The slipper shell is found in creeks and small rivers. Usually it needs fairly good quality water and is found buried in sand and gravel (Cummings and Mayer, 1992). Slipper shells are filter feeders, and they have been cultured on algae, but they may also ingest bacteria, protozoans and other organic particles. The slipper shell belongs to the order of Unionoida. The Alasmidonta marginata, also known as elktoe. The elktoe is found in the upper Mississippi drainage in the Ohio Cumberland and Tennessee River system as well as the Susquehanna River. The elktoe is usually found in larger creeks the upper reaches of rivers. (Cummings and Mayer, 1992). The elktoe are filter feeders, and they have been cultured on algae, but they may also ingest bacteria, protozoans and other organic particles. The elktoe belongs to the order of Unionoida. The slipper shell and elktoe are similar because they both are found in the upper Mississippi drainage, and in the Ohio Cumberland and Tennessee River. They are both filter feeders and they are cultured on algae. The difference between the slipper shell and elktoe are there size. The slipper shell is 3.80 cm high, and the elktoe is 10 cm high.

Since the initiation of the CPFR pilot program, it seemed that Valley, their supplier, had been making all the demands in this relationship.

After Bailout

...AFTER THE BAILOUT: REGULATING SYSTEMIC MORAL HAZARD* Karl S. Okamoto ** How do we prevent excessive risk taking in the financial markets? This Essay offers a strategy for regulating financial markets to better prevent the kind of disaster we saw during the Financial Crisis of 2008. By developing a model of risk-manager decisionmaking, this Essay illustrates how even “good people” acting in utterly rational and expected ways brought us into economic turmoil. The assertion of this Essay is that the root cause of the Financial Crisis was systemic moral hazard. Systemic moral hazard poses a unique challenge in crafting a regulatory response. The challenge lies in that the best response to systemic moral hazard is “predictive prevention.” It is inherently difficult to reward individuals for producing predictive prevention. Unsurprisingly, markets fail to produce it at optimal levels and thus cannot prevent systemic moral hazard and the kind of crises that ensue. The difficulty in valuing predictive prevention is seen when we model how risk managers make decisions regarding the prevention of excessive risk. The model reveals how the balance can be tipped in favor of risk taking that leads to systemic failure and broad social harm. The model also reveals how regulation might work to reset the balance to one that is superior for society. We can achieve optimal risktaking decisionmaking in two ways: (1) by requiring all asset managers in the market to put their own money at risk in...

Some chapters are more finished than others. References and attributions are very preliminary and we apologize in advance for any omissions (but hope you will nevertheless point them out to us). Please send us bugs, typos, missing references or general comments to complexitybook@gmail.com — Thank You!! DRAFT ii DRAFT About this book Computational complexity theory has developed rapidly in the past three decades. The list of surprising and fundamental results proved since 1990 alone could fill a book: these include new probabilistic definitions of classical complexity classes (IP = PSPACE and the PCP Theorems) and their implications for the field of approximation algorithms; Shor’s algorithm to factor integers using a quantum computer; an understanding of why current approaches to the famous P versus NP will not be successful; a theory of derandomization and pseudorandomness based upon computational hardness; and beautiful constructions of pseudorandom objects such as extractors and expanders. This book aims to describe such recent achievements of complexity theory in the context of the classical results. It is intended to both serve as a textbook as a reference for self-study.
