Does excessive exposure to violent video games cause violent behavior? Does increased gun availability cause more crime or less? Causal claims permeate everyday life and are constantly the subject of "studies" reported in the newspaper. The material in Causal and Statistical Reasoning examines the nature of causal claims and the statistical sorts of evidence used to support them. The material is contained in: approximately 20 content modules, a repository of over 100 short case studies, and a "C
Arrival of the Twenty-Second Indiana Volunteers
The soldiers are leaving the steamboat City of Alton and walking into St. Louis. Church steeples are in the background. A rowboat is on the shore with two men standing near it. The article says the sketch was made by one of the soldiers, and an excerpt from his accompanying letter is in the article. He says the regiment was in North Madison until August 14, 1861 when they received orders to proceed to St. Louis via Indianapolis. At the Mississippi River they boarded the steamboat City of Alton a

The Effective Provision of Pre-School Education (EPPE) Project: Technical Paper 8b - Measuring the I
This Technical Paper describes the results of analyses of young children's social behavioural development during their time in pre-school. Equivalent analyses of the cognitive progress of children in the study have been conducted and the results are reported separately in EPPE Technical Paper 8a. Four aspects of social behavioural development have been studied, namely 'Independence & Concentration', 'Co-operation & Conformity', 'Peer Sociability' and 'Anti-social / Worried'. . A range of statist
Poverty and Elimination of Urban Health Disparities Challenge and Opportunity
The aim of this article is to examine the intersection of race and poverty, two critical factors fueling persistent racial and ethnic health disparities among urban populations. From the morass of social determinants that shape the health of racial and ethnic communities in our urban centers, we will offer promising practices and potential solutions to eliminating racial and ethnic health disparities.
The effects of explicit teaching of morphemic analysis on vocabulary learning and comprehension and
This study investigated the effects of explicit teaching of morphemic analysis on vocabulary learning and comprehension and its transfer effects to novel words with sixth grade students. Because research states that vocabulary and the ability to decode unfamiliar words is vital for comprehension, an increase in vocabulary learning and comprehension was predicted. A sixth-grade reading class with low reading assessment results was specifically taught twelve affixes and roots chosen from a bank of
Where is Mr. Clean? Household division of labor and the pay gap between men and women
The household division of labor and the pay gap between men and women is examined using the 2003 American Time Use Survey. There are three components to an income determination model: individual, structural and gender level components. The individual component argues that people are rational human beings who make conscious decisions on how to maximize their utility, with increased investments in human capital possibly leading to increases in income. The structural component views society as orga
The effects of activating prior knowledge before reading on students with and without learning disab
Students with learning disabilities use prior knowledge differently than students without learning disabilities. This paper examines what happens to reading fluency, words per minute, and reading comprehension when prior knowledge is activated. By using two reading passages at the fourth grade level, students read one passage without prior knowledge activation and another with prior knowledge activation. The students were timed for words per minute. The reading errors were noted for fluency, and
The consequences of antisocial behavior in older male siblings for younger brothers and sisters
The contribution of younger male and female siblings’ conflict and involvement in deviant activities with their older brothers to younger siblings’ adolescent adjustment problems was examined in the context of parenting. Ineffective parenting during younger siblings’ childhood had no direct effects on adjustment, but facilitated their exposure to older brothers’ deviant peers and activities. The effect of sibling conflict on adjustment was mediated by younger siblings’ co-participation

2.72 Elements of Mechanical Design (MIT)
This course provides an advanced treatment of machine elements such as bearings, springs, gears, cams, and mechanisms. Analysis of these elements includes extensive application of core engineering curriculum including solid mechanics and fluid dynamics. The course offers practice in skills needed for machine design such as estimation, drawing, and experimentation. Students work in small teams to design and build machines that address real-world challenges.
3.14 Physical Metallurgy (MIT)
The central point of this course is to provide a physical basis that links the structure of metals with their properties. With this understanding in hand, the concepts of alloy design and microstructural engineering are also discussed, linking processing and thermodynamics to the structure and properties of metals.

Working with charts, graphs and tables
Your course might not include any maths or technical content but, at some point during your course, it’s likely that you’ll come across information represented in charts, graphs and tables. You’ll be expected to know how to interpret this information. This unit will help you to develop the skills you need to do this. This unit can be used in conjunction with the ‘More working with charts, graphs and tables’ unit, which looks into more ways to present statistical information and shows y
