1. What is the fundamental equation that guides changes to a weight w_ij in a BP network.   Describe its components.

2. Multi-layer BP neural networks have no proof of converging to an optimal solution. Is this true? If it is, then why do we bother to use them?

Due to changes in social structures such as the economy and corporate America, some argue the American Dream is no longer available to all Americans. On the other hand, others still believe anyone can climb the social ladder and experience social mobility. Think about whether you agree or disagree with the idea that social mobility is achievable for most Americans.

Write an essay expressing your opinion about social mobility and the American Dream. Be sure to explain the sociological terms structural mobility and life chances in your response. Integrate these terms and concepts to discuss whether the American Dream is achievable for most Americans.

Standard 1: Human Capital Management Educational leaders use their role as human capital manager to drive improvements in building leader effectiveness and student achievement.

Standard 2: Instructional Leadership Educational leaders are acutely focused on effective teaching and learning, possess a deep and comprehensive understanding of best instructional practices, and continuously promote activities that contribute to the academic success of all students.

Standard 3: Personal Behavior Educational leaders model personal behavior that sets the tone for all student and adult relationships.

Standard 4: Building Relationships Educational leaders build relationships to ensure that all key stakeholders work effectively with each other to achieve transformative results.

Standard 5: Culture of Achievement Educational leaders develop an encompassing culture of achievement aligned to the institution’s vision of success for every student.

Standard 6: Organizational, Operational, and Resource Management Educational leaders’ leverage organizational, operational, and resource management skills to support improvement and achieve desired educational outcomes.

Question 1 ( Apply information above to answer)  The work climate has proven to be an effective measuring stick to successful performance. Tell what effective educational leaders can do to ensure the work climate is conducive to fairness, crisis management, learning, professional development, and cultural diversity.

Tell what process can be utilized to measure work climate. As an educational leader, you have researched leadership theories and models. Name and explain how these varies theories and models can influence current educational situations of academic achievement in universities.

Suppose the U.S. Congress passes a budget which increases individual income

     taxes by $120 billion and increases infrastructure spending (airports, roads,

     bridges, etc.) by $50 billion. The increase in income taxes is concentrated at the top,

     so the tax increase causes personal consumption expenditures to fall by only $30

     billion. Use this information to answer the questions below. (20 pts)

            a. At constant interest rates (“other things equal”), what would these policy

                 changes do to national saving and domestic investment spending?

                        Change in S =

                        Change in I =

            b. Closed economy analysis: Assuming the U.S. financial system is closed to

                  international financial flows, draw an S/I diagram to illustrate the effect of

                  these policy changes on (1) U.S. interest rates and (2) the quantity of domestic

                  investment spending. Incorporate your numerical answers from part (a) into

                  your diagram.

-3-

            c. Open economy analysis: Now assume that the U.S. financial system is open

                 and that the U.S. is small enough in the global financial system that you can

                 ignore the effect of these policy changes on global interest rates. Draw an S/I

                 diagram to illustrate the effect of the policy changes on (1) U.S. net capital

                 flows and (2) domestic investment spending. When drawing your diagram,

                 assume that the U.S. would have had net capital inflow without the policy

                 changes.

Velshi Printers has contracts to complete weekly supplements required by forty-six customers. For the year 2015, manufacturing overhead cost estimates total $840,000 for an annual production capacity of 12 million pages.

For 2015 Velshi Printers has decided to evaluate the use of additional cost pools. After analyzing manufacturing overhead costs, it was determined that number of design changes, setups, and inspections are the primary manufacturing overhead cost drivers. The following information was gathered during the analysis:

Cost pool                          Manufacturing overhead costs             Activity level

Design changes                                                  $ 120,000    300 design changes

Setups                                                                  640,000               5,000 setups

Inspections                                                             80,000        8,000 inspections

   Total manufacturing overhead costs                   $840,000

During 2015, two customers, Money Managers and Hospital Systems, are expected to use the following printing services:

Activity                                                Money Managers       Hospital Systems

Pages                                                                     60,000                        76,000

Design changes                                                            10                               0

Setups                                                                          20                              10

Inspections                                                                   30                              38

25) Assuming activity-cost pools are used, what are the activity-cost driver rates for design changes, setups, and inspections cost pools?

26) Using the three cost pools to allocate overhead costs, what is the total manufacturing overhead cost estimate for Money Managers during 2015?

A) $13,700

B) $6,500

C) $6,860

D) $10,192

Unfavorable changes with time and due to various metabolic processes in body composition have long been observed with aging. Loss of lean mass (LM) and accumulation of abdominal fat are most important changes that continuously take place in all adults and individuals as they age. All these events have been found to be associated with an increased risk of the development of type 2 diabetes in older adults. This is of high importance from a public health perspective where aging of the population specially developed countries is considered a factor contributing to the global burden of type 2 diabetes. The pattern and rate of age-related changes in body composition will vary by sex, race, region, physical activity level, diet and caloric intake. Recent evidences from longitudinal studies have shown differences in the pattern of body composition changes in adults by diabetes status. In this article, we reviewed body composition changes that take place in adults after the diagnosis of type 2 diabetes and compared them to those observed in adults without diabetes as they age.
