What Is an Enzyme?

An enzyme is a protein that acts as a biological catalyst. Its primary function is to increase the rate of a natural chemical reaction. Enzymes typically react with one specific substrate, and their activity is regulated within the cell through various means, including inhibitors and activators.

Enzyme Structure

Most enzymes are proteins with three-dimensional shapes determined by their specific amino acid sequences.

Key Concepts in Enzyme Activity

• Substrate: When a substrate molecule binds to the highly specific active site of an enzyme, an enzyme-substrate complex is formed. This complex modifies the substrate and initiates a series of chemical reactions, resulting in the formation of a product.
• Transition State: The highest

MARKET VALUE PERFORMANCE MEASURES

MVA

Market Capitalization = (#shares * price per share) - Equity

MTBR

Measures how much value has been added for each dollar that shareholders have invested = MVOEQUITY / BVOEQUITY

MEASURING PROFITABILITY

EVA

Economic Value Add or Residual Income = The profit after deducting all costs including the cost of capital = After-tax operating income (after tax interest + NI) - (cost of capital * total capitalization at the start of the year) = ((1- tax rate)(interest expense) + NI) - (cost of capital)(long term debt + total equity beginning of year)

ROE

NI / Equity start

ROA

(1-tax rate) * interest expense + NI / Total Assets start

ROC

(1- tax rate) * interest expense + NI / LTD start + Equity start

MEASURING EFFICIENCY

How effectively... Continue reading "Financial Performance Measures and Analysis" »

• Preferential Trade Agreement or Free Trade Area: A trading bloc involving cooperation between at least two countries to reduce or eliminate trade barriers and increase the exchange of goods and services.
• Customs Union: Participant countries establish a common external trade policy. Goals typically include increasing economic efficiency and fostering closer political and cultural ties.
• Common Market: Factors of production move freely between member states.
• Economic and Monetary Union: Features a common monetary policy, a single currency, harmonized tax rates, and a unified fiscal policy.
• Political Union: Involves a common government.

Tracking website user behavior doesn't happen automatically. The web developer needs to install a web analytics program into every page of the website they wish to track.

The Web Analytics Data Collection Process

1. An internet user takes an action that results in a request for a page on a website.

2. When the user navigates to the webpage, the web server receives a request for the information. The server sends this information across the internet to the requesting computer. The web server will then pass on some information about this server request to a data collection center run by the analytics package.

3. The data collection center stores data about this server request and all other server requests until a user requests this data through the analytics

Vector Determination by Length and Angle

V = <||V|| Cosθ, ||V|| Sinθ> ---> ||V||Cosθi + ||V||Sinθj

Example:

a) Find the vector of length 2 that makes an angle of π/4 with the positive x-axis.

b) Find the angle that the vector V = -₃ i + j makes with the positive x-axis.

a) <||V||Cosθ , ||V||Sinθ> = <2cos45, 2sin45> ---> <₂, ₂>

b) Normalize... ||V|| = _{(-3)² + 1²} = ₄ = 2 -----> V/||V|| = <-_3/2 , 1/2> = <cosθ, sinθ> ----> cosθ = -_3/2, sinθ = 1/2 ---> θ = 5π/6

Dot Product

If U = <U₁, U₂> and V = <V₁, V₂>, then the dot product is U•V = U₁V₁ + U₂V₂.

Example:

a) U = <3, 5>, V = <-1, 2> -----> U•V = (3)(-1) + (5)(2) ---> U•V = -3 + 10 --> U•V = 7

b) U = &... Continue reading "Vector Operations, Dot and Cross Products, and Lines" »

The Lifeblood of the 20th Century

If we talk about the lifeblood of the 20th century, it must be said that one of the most important and representative elements of this era was oil and the industries that surrounded it.

John D. Rockefeller and Standard Oil

John D. Rockefeller was one of the wealthiest men in American history and a primary architect of the modern economy. He founded Standard Oil, a monopoly that dominated the sector. Rockefeller utilized aggressive marketing strategies, such as predatory pricing, to eliminate competitors. Furthermore, he vertically integrated his services, acquiring rival companies and managing public relations to ensure his success. By the 1900s, he controlled 90% of US oil capacity. Although his company was eventually... Continue reading "The Rise of Standard Oil and the Impact of Black Gold" »

Brand Sponsorship

1. Manufacturer and Private Brands

Manufacturers have historically dominated the retail scene. Today, retailers are creating their own private brands to set their own prices and fend off manufacturer competition. To succeed, retailers must invest in research and development (R&D), manage the high costs of stock, and effectively promote their products, which can be difficult to establish.

2. Licensing Brands

Creating a brand from scratch takes years and significant capital. Some companies choose to license names or symbols created by other manufacturers. For a fee, this provides an instant and proven brand identity.

3. Co-Branding

Co-branding occurs when two established brands from different companies create a new product to... Continue reading "Brand Sponsorship, Product Strategy, and Marketing Mix" »

Values and Modernization – Conceptual Framework Modernization theory builds on a long tradition stressing the Potential and extent of human progress. Generalized expectation that socio-economic modernization Effects value change. Enlightment: Science and reason set individuals free Marx: Technological change and capitalism makes Communism possible Smith: Technology is a source of wellbeing Postwar theorists: Some values favor economic progress While other ones not (e.G. Parsons) Nevertheless, classic modernization theory underspecifies (a) Mechanims and (b) types of values brought by modernization.
