Explain why the increase in the overhead rate should not have a negative financial impact on Borealis Manufacturing

April 25, 2018 3 Comments Uncategorized

Borealis Manufacturing has just completed a major change in its quality control (QC) process. Previously, products had been reviewed by QC inspectors at the end of each major process, and the company’s 10 QC inspectors were charged to the operation or job as direct labor. In an effort to improve efficiency and quality, a computerized video QC system was purchased for $250,000. The system consists of a minicomputer, fifteen video cameras, and other peripheral hardware and software. The new system uses cameras stationed by QC engineers at key points in the production process. Each time an operation changes or there is a new operation, the cameras are moved, and a new master picture is loaded into the computer by a QC engineer. The camera takes pictures of the units in process, and the computer compares them to the picture of a “good” unit. Any differences are sent to a QC engineer, who removes the bad units and discusses the flaws with the production supervisors. The new system has replaced the 10 QC inspectors with two QC engineers.

The operating costs of the new QC system, including the salaries of the QC engineers, have been included as factory overhead in calculating the company’s plant-wide manufacturing-overhead rate, which is based on direct-labor dollars. The company’s president is confused. His vice president of production has told him how efficient the new system is. Yet there is a large increase in the overhead rate. The computation of the rate before and after automation is as follows:

	Before	After
Budgeted Manufacturing Overhead	1,900,000	2,100,000
Budgeted Direct Labor Cost	1,000,000	700,000
Budgeted Overhead Rate	190%	300%

Three hundred percent,” lamented the president. “How can we compete with such a high overhead rate?”

Review the situation. Complete the following:

Define “manufacturing overhead,” and:
- Cite three examples of typical costs that would be included in manufacturing overhead.
- Explain why companies develop predetermined overhead rates.
Explain why the increase in the overhead rate should not have a negative financial impact on Borealis Manufacturing.
Explain how Borealis Manufacturing could change its overhead application system to eliminate confusion over product costs.
Describe how an activity-based costing system might benefit Borealis Manufacturing.

Write a 3–4-pages paper in Word format. Apply APA standards to citation of sources.

Section: 01

Term: Winter 2014

Instructor: Dr. Dajana Vuckovic

Due date: 11:40 am before the beginning of the class on January 29, 2014 in CC-320

TOTAL POINTS: 55

General instructions:

§ You must show full/detailed calculations to receive full marks for each problem.

§ Please show your FINAL answer to correct number of significant figures. During intermediate steps, keep all digits in your calculator to avoid large rounding errors in the final answer. In other words, do not round off your answers during intermediate calculation steps.

§ Write in pen.

§ Use K_SP values from textbook – Harris 8^th edition

1. (8points) An analytical lab needed to determine the content of phosphorus in a commercial sample of plant food. The phosphorus in a 4.258 g sample of this plant food was converted to PO₄^3- and precipitated by adding 50.00 mL of 0.0820 M AgNO₃. The excess AgNO₃ was then titrated using 4.06 mL of 0.0625 M KSCN. What was % P₂O₅ in the original plant food sample?

P₂O₅ + 9 H₂O → 2PO₄^3- + 6H₃O⁺

2PO₄^3-+ 6 Ag⁺→ 2Ag₃PO_4(s)

Ag⁺ + SCN^–→ AgSCN_(s)

…….

….

2. A solution of volume 25.00 mL containing 0.0311 M Na₂C₂O₄was titrated with 0.0257 M La(ClO₄)₃ to precipitate lanthanum oxalate:

2 La³⁺ + 3 C₂O₄^2-

La₂(C₂O₄)_3(s)

(a) (2 points) What volume of La(ClO₄)₃ is required to reach the equivalence point?

(b) (3 points) Find pLa³⁺ when 10.00 mL of La(ClO₄)₃has been added.

(d) (3 points) Find pLa³⁺when 25.00 mL of La(ClO₄)₃has been added.

(e) (5points) Plot the titration curve for this titration using Excel or other spreadsheet software

(f) (8points) Plot the titration curve for the same titration if the concentration of the titrant is increased to 0.0500 M. What effect does this have on the shape of the titration curve?

(g) (3points) Another analytical chemist performed the titration of the same oxalate sample using calcium to precipitate calcium oxalate. Is this a better approach to this analysis? Why or why not?

3. (a) (10points) Calculate pCu⁺ for the titration of 10.00 mL of 0.05000 M of I^–with 0.02500 M Cu⁺ standard solution when 4.500 mL, 20.00 mL and 21.40 mL of titrant have been added. Plot the titration curve for this titration using Excel or other spreadsheet software.

(b) (10points) Calculate pCu⁺ for the titration of 10.00 mL of 0.05000 M of Cl^– with 0.02500 M Cu⁺ standard solution when 4.500 mL, 20.00 mL and 21.40 mL of titrant have been added. Plot the titration curve for this titration using Excel or other spreadsheet software on the same graph as (a). How does K_sp value influence the shape of the observed titration curves?

Question:

Was China right in passing the isolation trade policies and causing the war? Or should they have maintained the status quo allowing opium into the country?

Paper instructions:
The paper has to make use of all the sources in the bibliography attached. The original topic/argument is inside along with the thesis statement, however as professor commented, my argument could not be backed up by the primary sources I provided. Can you help me think of a new argument related to The Opium War that could use all the sources I provided.

IAS 45: RESEARCH PAPER

Topic Due: February 25th

Primary Source(s) Due: March 18th

…….

….

Thesis Paragraph & Bibliography Due: April 8th

Final Paper Due: April 24th

This course covers many different societies across millennia. This assignment asks you

to choose one crosscultural

encounter to evaluate. While you will need to pick a specific topic,

we encourage you to think expansively. You need not limit yourself to traditional narratives or

actors; race, gender, and class are all important issues in crosscultural

encounters. Below, we

outline the guidelines for this task. It is your job to find a reasonable topic within these

parameters that interests you. Then, through consultation with your GSI, you will narrow down

this topic and look for sources. You will then engage these sources, both analyzing primary

sources and considering them in the context of existing historiography. After becoming familiar

with your sources, you will craft an argument (not a story) using your evidence to support it. Your

paper must be 710

pages (doublespaced,

in 12point

font).

…….

….

Method: Your paper should make an argument or claim based on the careful analysis of at

least one (and preferably two) primary sources, supported by the use of at least one secondary

source. The challenge here is to formulate a question that is both answerable (not too big) but

will also shed interesting light on one of the big themes of world history we have been discussing

this semester (not too small). You may not use sources assigned in this class nor can you use

sources that are entirely available on the internet, including but not limited to Wikipedia.

Topics: You must limit yourself to topics from the following themes and chronological periods

(broad examples below each).

● New Encounters in the Age of Exploration, 15th to 17th centuries

○ The Spanish Conquest, The Spread of Christianity, Slavery, Old and New World

Exchanges After Columbus, European Missions in Asia

● Industrial Revolution, mid18th

to mid19th

centuries

○ The Market/Industrious Revolution, The Rise of Labor, The Emergence of a

Global Market

● Age of Empire: Colonialism in Asia and Africa, 19th century

○ The Opium Wars, The Meiji Restoration, The Scramble for Africa, India, and

Southeast Asia

● Decolonization and the World Wars: First, Second, and Cold

○ The Russian Revolution, The Emergence of the First, Second, and Third Worlds

Marketing

April 25, 2018 3 Comments Uncategorized

An important objective of this class is to see how managers can apply our in-class concepts to better market their products. This could entail discovering opportunities for new products or services or preparing for restructuring of an industry or developing better marketing strategies.

Below are listed 6 issues/problems that entail recent changes in consumer behavior that present opportunities for new businesses (and threats to current ones). Each group is required to select 1 such issue/problem, identify what factors are causing this problem, analyze the problem thoroughly in all its aspects by conducting surveys (n=20-30) among relevant multiple segments (e.g., university disruption – students, parents, administrators, and faculty) and present strategies that companies can adopt either to better prepare themselves for those changes and/or improve their marketing strategies and/or to introduce new products/services.

…….

…..

The problem is :
6. There are several changes taking place in the spatial/geographical aspects of where people decide to live in a city/town. For example, increasing number of people want to move from suburbs to downtown (in contrast to a dominant trend of last several years of more consumers wanting to live in suburbs). Please list 2-3 such big changes, why are they taking place, what issues and challenges they present for marketers and retail stores, and what can they do to respond to those changes.

A) Problem Definition Section explains the issue/problem in all its aspects and identifies its causes and the challenge(s) it poses for current players in that industry. If you choose, you can select one player or brand in the industry (vs. the whole industry). (Aspects and causes-25pts; Challenges-15pts) 40 points

B) Survey Findings Section presents findings from surveys of multiple relevant segments 20 points

C) Marketing Strategy Section connects the first two sections (and not based on your subjective opinion) to explain 4-5 specific strategies for current player(s) to either better market their product or better prepare for impending changes or provide specifics about introducing the new product/idea. 40 points
