2006 essay Troublemakers provides an interesting discussion about how we use generalizations in organizing and regulating our society. He frames his discussion with a consideration of the 2005 law banning pit bulls in Ontario‚ but in between he refers to generalizations in insurance (young male drivers pay higher premiums)‚ medicine (overweight males will be counseled to have their cholesterol checked)‚ law enforcement (what markers are used to identify terrorists) and our perceptions about crime rates

In daily life‚ you can find out man many generalization easily; such as‚ when you heard about crime‚ you immediately think of the drunken‚ unemployed‚ color people..etc‚ or when you heard about Havard’s student‚ words describing like very smart‚ creative‚ sucess in life easily or something like that glance through your mind.In the same way‚ when you heard people depend on welfare‚ you immediately think that they are lazy‚ unemployed‚ have many children‚ never try to get any job and they are black

In reviewing Towns’ article "ARGUMENTS THAT THE BIBLE IS THE WORD OF GOD"‚ I found all of the information compelling‚ but what stood out the most was the empirical fulfillment of prophecy. I strongly believe that the bible is God’s word‚ but the fulfillment of prophecies validates any ambiguity. Town’s states "Christianity is the only religion that gives fulfilled prophecies as one of its bases for credibility" (p.4 ). That notation alone speaks volumes; other religions are waiting for prophecies

Empirical and Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical

Empirical Formula of a Compound * Purpose: To determine the empirical formula of Magnesium Chloride. * Data 1. Mass of evaporating dish = 45.08g 2. Mass of evaporating dish and Magnesium = 45.17g 3. Mass of Magnesium: { 2 } – { 1 } = 0.09 4. Mass of evaporating dish and Magnesium Chloride First weighing = 45.48g (After heating and cooling) second weighing = 45.49g 5. Mass of Magnesium Chloride: { 4} – { 1 } = 0.41g

1) Empirical study-a study that uses tangible observations. The data collected comes from physical means that are concrete and use the senses to gather data. (McMillian‚ 2016‚ p.7) Example: Empirical studies can be quantitative or qualitative; in research involving retention efforts they will be empirical studies conducted to gather data. 2) Theory- is an educated assumption that explains how‚ what we as researchers examine relate to each other. It creates meaning from the information gathered. McMillian
