What is Injection Molding?

Injection molding is a manufacturing process for producing parts in large volumes. It is most typically used in mass-production processes where the same part is being created thousands or even millions of times in succession.

Why Use Injection Molding?

The principal advantage of injection molding is the ability to scale production en masse. Once the initial costs have been paid, the price per unit during injection molded manufacturing is extremely low. The price also tends to drop drastically as more parts are produced. Other advantages include the following:

• Molding is very repeatable. That is, the second part you produce is going to be practically identical to the first one. This is a wonderful

G.A. Cohen's Locked Room Analogy

The story of G.A. Cohen presents a scenario where ten people are locked in a single room with only one key able to open the door. This thought experiment is used to analyze the concepts of freedom and necessity within the capitalist system.

The Analogy's Components

The room is similar to the working class, the people locked in the room are the individual workers, and the key represents the means with which individual workers can escape the working class. It must also be noted that only one individual may use the key and leave the room, and after that individual leaves, no other individual may attempt to exit.

The Argument for Individual Freedom

It is true that before anyone attempts to leave, all are equally free... Continue reading "G.A. Cohen's Locked Room Analogy and Capitalist Exploitation" »

Cool Jazz

In part a reaction to bebop, cool jazz involved more complex compositions, slower tempos, and sometimes less overt emotional involvement. Associated with the West Coast, it had much greater rhythm variety than bop in up-tempo & medium-tempo pieces. It had extensive arrangements, including written introductions and composed passages between improvisations.

Artists

• Paul Desmond
• Dave Brubeck
• Bill Evans

Hard Bop

Hard bop is a subgenre of jazz that is an extension of bebop music. Journalists and record companies began using the term in the mid-1950s to describe a new current within jazz which incorporated influences from rhythm and blues, gospel music, and blues. An aggressive, driving, hot style of modern jazz developed by East Coast musicians... Continue reading "Exploring Different Styles of Jazz: Cool Jazz, Hard Bop, Free Jazz, and Fusion" »

The ability of a firm to produce good performance depends on the strategy of an organization. The strategy of an organization, in turn, depends on the environment and culture of an organization. The environment is the sum name of all those factors and forces which not only surround an organization but also affect the way it works and its performance (external factors outside the organization and internal factors within the organization). Culture is the way an organization and its people work. Usually known as organizational culture, it includes:

• Values: Easy to identify, they are explicit, and used to be different from formal statements.
• Beliefs: Specific, discerned in how people talk about issues the organization faces.
• Behaviors: Day-to-day

Management of Interest Rate Risk

Major Risks in Bond Market

A) Interest Rate Risk (change in market prices of bonds due to varying interest rates)

• Increase in rates, decrease in market prices, increase in reinvestment rate risk (coupons reinvested at lower return)

B) Reinvestment Rate Risk (uncertainty of rate at which interim cash flows can be reinvested)

• High coupon rate, high reinvestment rate risk
• Greater for longer holding periods (high interim cash flows)

C) Default Risk (credit risk) (issuer unable/unwilling to pay interest and principal of bond)

• High credit rating, lower yield

Early Chordates and the Rise of Tetrapods

The earliest known chordate, Myllokunmingia, is found in the Chengjiang fauna. One of the major challenges for early tetrapods was supporting their bodies on land, along with reproductive and sensory adaptations. Tetrapod limbs consist of three segments: the stylopod (humerus/femur), zeugopod (ulna/radius, tibia/fibula), and autopod (wrist/fingers, ankle/toes). Tiktaalik represents a key transitional fossil between fish and tetrapods.

Amphibians and Amniotes

Amphibians, with over 4,000 living species, represent a halfway point in the transition to land. They still rely on water for breeding and maintaining water balance. Amniotes, including reptiles, birds, and mammals, evolved a semipermeable shell made... Continue reading "Evolution of Life: From Early Chordates to Modern Biodiversity" »
