Drawing on Suzanne Scott’s analysis of fandom and gender, consider how media industries and cultural gatekeepers shape the representation and participation of fans, particularly women and marginalised groups. What are the implications of this for our understanding of fandom’s role in contemporary media culture?

Reforming of liquid fuels to hydrogen is being considered to enable hydrogen-powered fuel cells
to be used to generate remote power. For example, the military is interested in using hydrogen
fuel cells to replace conventional batteries, which have a low power density and a short lifetime.
Reforming, then, could be used to transform military fuels to hydrogen to power fuel cells.
Autothermal reforming is one means for converting liquid fuels to hydrogen. In this process, the
liquid fuel is reacted with oxygen and water to produce hydrogen. The overall reaction involves
multiple reactions. Assuming that isooctane (2,2,4 trimethyl pentane) is the fuel, the overall
reaction scheme can be written:
C8H18 + 12.5 O2 8 CO2 + 9 H2O
C8H18 + 8 H2O 8 CO + 17 H2
C8H18 + 8 CO2 16 CO + 9 H2
C8H18 + 16 H2O 8 CO2 + 25 H2
CO + H2O CO2 + H2
Your assignment is to model the reforming of isooctane in a packed-bed reactor.
Reaction Kinetics
Pacheco, et. al. (Pacheco, 2003) fit experimental data for a proprietary Pt/CeO2 catalyst to obtain
reaction kinetics for each of these reactions. The reaction rate laws they used are shown in
Table 1, where the reaction order corresponds to that shown above, and the rate law constants
are given in Table 2.

Standards For Standards
Review the “NASW, ASWB, CSWE, and CSWA Standards for Technology in Social Work Practice.” For this discussion:
Consider a scenario of using technology in social work practice. A real experience is better, but if you do not have one, consider any example. Briefly explain the scenario in your post.
Identify at least two specific standards that apply and explain their use specific to your scenario. Cite the specific standards in your post.
Impacts of climate change pose a threat to U.S. national security
To what extent does the prospect of failed states and “ungoverned spaces” resulting from the impacts of climate change pose a threat to U.S. national security? In what ways does recent history provide some context for addressing this question?
Advantages and disadvantages of bringing in a private management
in 150-200 words answer the following question with references
Explain the advantages and disadvantages of bringing in a private management company such as SMG or Global Spectrum to manage a public sport facility. If you were the lead government official in your municipality, would you hire private management or keep the facility under in-house control? Why?
Religion and IB.
Read Case Study 6 – Religion and IB.pdf which is a study conducted on the importance of religion in international business negotiations. This study covers only one religion, Islam, in one country, Malaysia; however, I want you to look at their findings and relate them to your knowledge of Christian businesses. Do you think there are any similarities or any differences? What would be your suggestions to any religious person, regardless of religion, who is put in a place of making negotiations with either people of other religions, the same religion, or no religion at all?
Health Technology Policy Analysis
Technology has proven effectiveness in speed of information transmission, which leads to prompt healthcare service delivery, prompt treatment of illnesses and better health outcomes. Policies drive the success of health technology through practice standardization. However, cost, safety and security, ethics, and legality have all been target areas of health technology policies. In a minimum of 250 words, discuss the following:
Define health technology policy.
What are some key terms in health information technology? List and define two.
What organizations safeguard health policies? List at least two organizations and a policy they safeguard.
Provide a brief description of the U.S. Food Drug Administration’s (FDA’s) role in health policy.
The Morningstar mutual-fund rating system
You have just received an inheritance of $10,000 and you decide that you should invest the money rather than blow it on frivolous items. You have decided that you will invest the money in one of two types of mutual funds. The first type that you are considering follows a large-value approach to investing. This means that the mutual fund invests only in large, established companies that are considered to be a good bargain. The second type following a large-growth approach to investing. This means that the mutual fund invests in large companies that are experiencing solid revenue growth. To make an informed decision, you decide to reach the rate of return for the past 3 years for each type of mutual fund. The mutual fund must have a Morningstar rating of four or five stars.
The Morningstar mutual-fund rating system ranks mutual funds, using one to five stars. The stars divide the mutual-fund performances into quintiles: that is, a mutual fund with a one-star rating is in the bottom 20% of mutual funds in its category, a mutual fund with two-stars is in between the 21st and 40th percentile, and so on. These data can be found at www.morningstar.comLinks to an external site. or screen.yahoo.com/funds.htmlLinks to an external site.
Obtain a random sample of at least 15 mutual funds from each investment category. Determine the 3 years rate of return for each fund.
Obtain a 95% confidence interval for the difference between the mean rates of return. Interpret the interval.
You are going to write a report detailing which investment category seems superior.
