Eastern and Western Ethical Perspectives: Bridging the Gap

Individualism vs. Collectivism: One noticeable distinction between Eastern and Western ethics lies in the emphasis on individual rights and autonomy in the West, and the focus on communal harmony and family values in the East. How do these contrasting values impact the understanding of ethical dilemmas and societal responsibility?  

TRUE OR FALSE QUESTIONS

1-A fund in itself is a separate legal entity that isestablished to comply with laws that require that certaintransactions be segregated and accounted for as a separate"fund."

2-The Financial Accounting Standards Board (FASB) sets generallyaccepted accounting principles (GAAPs) for non-governmentnot-for-profit organizations, while government non-profitorganizations must follow GASB.

3-The size of a government’s operations does not necessarilycoincide with the number of funds it establishes.

4-The MDA section of the basic financial statements is anintroduction of events that have occurred in the organization aswell as the possible effects of events that might happen.

5-The government wide financial statements are presented inaddition to fund financial statements and include the entity’sfiduciary activities.

6-The budget of an NFP organization is not integrated into therecord-keeping procedures and the applicable financial statements,as it is for governmental entities.

7-Certain revenues are precluded by GAAP from being recorded inspecial revenue funds. Revenues that are earmarked for expendituresfor major capital projects should be recorded in special revenuefunds.

8-NFP organizations adjust the value of their long-term debt fordiscounts or premiums on issuance of the debt, whereas governmentslist their long-term debt in the General Long-term Liabilitiesaccounts at face value even though it may have been issued at adiscount or at a premium.

8-Because they use full accrual accounting, NFPs account fordepreciation. There is an exception, however, in regard to certainassets that have collection value which are preservable in theircurrent condition, and have a claim on resources sufficient topreserve them indefinitely.

10-Proprietary funds use the accrual basis of accounting and theeconomic resources measurement focus. Accordingly, proprietaryfunds recognize revenues when they are earned and recognizeexpenses when a liability is incurred.

11-The basis of accounting describes when transactions arerecorded, not what transactions are recorded. Accordingly,allocations such as depreciation and amortization are not recordedas expenditures of governmental funds, nor are long-termliabilities.

12-Governmental funds use the current financial resourcesmeasurement focus, which recognizes as expenditures those coststhat result in a decrease in current financial resources.

13-Routine employer contributions from the general fund andinternal services billings from the enterprise fund are treated astransfers between funds.

14-The GASB requires each governmental entity to prepare aCAFR.

15-The budget for Virginia Beach authorizes expenditures of 12million and forecasts revenues of 10 million for 2016. The entry torecord the budget in the General Fund is as follows (trueor false).

D-Deferred gain from a sale and leaseback transaction.

16-GASBS 34 updated the types of fiduciary funds to includeEnterprise funds. TRUE OR FALSE?

17-Identify 4 main (the big) differences between fund accountingand proprietary accounting.

Comment on this base on ethical and cultural orientation

A man, who is from a prominent family in India, was the Director of the Art Museum. While he did a nice job in many regards, he was not coming in under budget. He was spending in excess of budget, and so the museum had to look to donors to find the difference. As such, it made me think about this topic around what ethical behavior is, and whether ethical behavior looks different to those from the Eastern world verses those from the Western world. He may have thought he was doing what was right for the organization, as he comes from a society where collectivism is valued more that individualism, and perchance this explains to some degree the difference between their expectations around what was ethical practice. 

Imagine you're working on a project with a diverse team that includes members from different cultural backgrounds and generations. How do you think cultural and generational differences might impact communication, collaboration, and decision-making within the team?

Additionally, considering college students preparing to enter the workforce, what specific cultural considerations or skills do you think they should develop to navigate these differences successfully in a professional setting?
