5. Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.

A sample of 75 stocks traded on the NYSE that day showed that 26 went up.

Sustaining Organizational Infrastructure

In order to successfully introduce change in an organization, it requires effective leadership by way of planning, organizing, directing and controlling the management of change. In the ever changing environment of health care, organizations are adopting a framework to implement change as an evolving system.

A model of leadership for change requires a vision, strategy and the development of a culture of empowerment, motivation and organizational citizenship. Model of leadership for sustaining operational infrastructure engages a vision to align employees with a core ideology of their organization. Building a sustainable concept of leadership model may serve as a supporting variable in the creation of an environment which fosters continuous quality improvement. If the process of developing and sustaining an operation infrastructure is going to be successful, the first and foremost importance involves the substantive involvement of top leaders.

Top leaders conceptualize key deliverable functions and align those functions fulling the needs of the key stakeholders and the organization. The functions for a sustainable operational infrastructure include: boundary spanning, forecasting, knowledge management, accountability and corporate design, continuous improvement and operational improvement. The function of sustaining the operational infrastructure process is an approach by which the people, structure, culture and social networks are recombined through the strategic assessment based on strengths and weaknesses. In this process, health care leaders generally find ways to work cooperatively within the organizational system to lead an organizational transformation and evidence-based approach. The ideology behind this approach is to disclose a strategic plan of organizational mission, vision, goals and values to its members to influence organizational citizenship behaviors.

Please choose one of the 2 options from below to write and essay. an essay should be about 300 words or more is fine. Avoid using quotations from secondary sources in your paper–as much as possible, everything should be described in your own words. If need be, you can quote short phrases but from primary texts only. So for example, you can quote a phrase from Descartes’ own writings (as quoted by Soccio) but not Soccio’s description of or commentary on Descartes.

Question C: Write an essay in which you explain how Immanuel Kant responds to David Hume’s epistemological concerns (how he is influenced by him) while also moving definitively beyond Hume’s radical skepticism. In doing so, make sure to explain the “transcendental” structure of his metaphysical ideas. Lastly, state if you are more sympathetic to Hume or Kant (or neither) and explain why.

Question D: Soccio discusses Jean-Paul Sartre as an example of a “public philosopher”. Begin by describing how Jean-Paul Sartre weaves together the concepts of freedom and responsibility (for Sartre these must always be thought together) and explain how these ideas shape his larger critique of modern society and/or his vision of philosophy as a way of life.  Then, finally, compare and contrast Sartre’s philosophical approach with that of Socrates. Make sure to clear describe at least major commonality in their understandings of the role of philosophy as well as one major difference.

 

The Final Paper is worth 200 points. You are required to visit a reputable art museum in your area and select a work of art to discuss and critique in a formal, iconographic, and historical context. Your grade will be based on the depth of your analysis of the subject.

About art criticism

The process of art criticism involves description, formal analysis, interpretation and evaluation. The first step is to describe what you see. Include facts, such as the artists name, the media, size of the piece, and where it is located. Next, analyze. Look at how all the parts of the piece work together. What visual elements and principles of design did the creator use? Subjectively interpret what the content is, taking style into account. Finally, interpret and evaluate the work of art being studied; what do you think the artist’s intentions were? What is being communicated? Does it have value? Can you recognize the aesthetic quality in the work? Include biographical and/or historical information. Evaluation can be a very challenging part of art criticism and requires practice and careful seeing.

Requirements

Select a museum

First, select a major museum in your area. A listing of some approved museums may be found at the following site: Art Museums Worldwide opens in a new window. If you live in a more rural area or are military and stationed overseas where you cannot visit a museum, contact the instructor to discuss options. An online museum visit may be necessary. However, in-person museum experiences will be prioritized. If the museum you’d like to visit is not on the list, you must get instructor approval.

If a virtual museum is necessary, you may find listings at the following site: Arts and Culture opens in a new window

Select a work of art

The following outline is suggested, but not required:

• Identification: Select a work of art. You may select a piece that you like or dislike. Get all the information provided: artist, title, medium, year, etc. Write down your initial responses. How do you respond to the work? Does it invoke an emotional response? What do you think the artist was trying to communicate? It is helpful to bring a notebook to record your responses.
• Describe the piece and review it carefully. What do you see? Note all the details about the work. How would you describe it to someone you were talking to on the phone who can’t see it?
• Analyze the visual elements and design principles, thinking about the relationship between form, content, and subject matter. This will be helpful in your ‘interpretation’ of the work. Consider context: does it fit into a movement or time period? Consider its place in the artist’s overall output.
• Interpretation Follow your analysis with a subjective interpretation of the meaning of the work. How does the work make you feel? What do you think the content is? Go beyond “I like it” or “I don’t like it.”
• Research the artist. Historical and biographical information on the artist often provides clues into a work’s intended meaning. Carefully consider the purpose and context of the piece. Did the piece you selected have any particular political or cultural message? Was the artist making a statement?
• Evaluate What do you think the artist’s intentions were? Was this communicated? Does it have value? Can you recognize the aesthetic quality in the work?

Format Requirements

The paper must be 1500 words, double-spaced, 10- or 12-point type, with 1” margins. The title page, images, and reference/bibliography page do not count toward the required length of paper.
