1) In the event of a major disaster, is it conceivable that victims might go to an outpatient or community-based clinic for treatment?What are some strategies Jeannette can use to persuade the clinic managers of the importance of having an up-to-date EOP in place?

2) How will nursing unions affect other members of the interprofessional team (e.g., physical therapy, dietary, pharmacy), which is essential for quality patient care? Will the nurses’ collective bargaining contract create inequities for other professionals?

3) Will nurses be too reluctant to strike? This is one of the most powerful tools that a union has at its disposal. There is concern that strikes by nurses could negatively affect patient care and destroy the public’s image of nursing. More importantly, the strike is contrary to nursing ethics and licensure to do no harm and avoid patient abandonment.

4) What resources are available to Addison to help her learn more about labor and management issues occurring in the hospital?Are there relevant gains to be made for the nursing profession and for improved patient care through collective bargaining—or is this a myth?

5) How can Addison establish good relationships with both nurse managers and staff nurses in an atmosphere in which collective bargaining has put these two groups in adversarial positions?How can Elena improve the marketability of her nursing expertise?

6) What are some of the potential obstacles to introducing complementary and alternative therapies into a conventional setting?What discipline(s) should be responsible for providing and/or coordinating or supervising the practitioners who provide complementary and alternative therapies in the hospital?

7) Could the patient sue the charge nurse if she had drawn the blood sample and given it to the police officer?What would the likely claims of nursing negligence be if a lawsuit had been filed on behalf of the patient?What was the nurse’s legal duty in this situation?

8) In this situation, does the police officer’s order to draw the blood supersede the nurse’s right to refuse the order?How will ethical and bioethical issues in nursing and health care affect my professional nursing practice? What ethical theories and principles serve as a basis for nursing practice?

9) With so many variations in health care insurance, I have a hard time understanding my own policy coverage. What role do I have in helping my patients understand their insurance or coverage options? Can being a more informed consumer add value to my practice?

10) Define the estimation error. Apply the generalized Wirtinger calculus to the expected value of the estimation error multiplied by its complex conjugate; the product, in its intact form, represents the cost function. Define the cost function in its expanded form, using the expectation operator.  Apply the generalized Wirtinger calculus.

11) A data stream consisting of i.i.d. symbols is applied to a binary phase-shift keying (PSK) system. The resulting modulated signal, x(n), is applied to a linear channel of unknown impulse response. For blind equalization of the channel, the constant-modulus algorithm (i.e., the Godard algorithm with p = 2) is used. (a) Plot the error signal e(n) versus the decoded sequence y(n). (b) Assuming the use of the signed-error version of the CMA, plot the piece-wise approximation of e(n). (c) Formulate the CMA and its signed-error version. You may refer to footnote 7 for a brief description of the signed-error CMA.

12) Change the problem description minimally, keeping the IDBD parameter unchanged, so that the IDBD algorithm diverges. For example, you may increase the value of the input by 10-fold or increase the variances of the white noise by 100-fold. Hence, respond to the following two questions for each example case:   (i) Why does the IDBD algorithm diverge?   (ii)  What is the minimal change required in IDBD parameters (e.g., the initial step-size parameter, m(0), or the meta-step-size-parameter, k) so that the divergence is prevented?

13) (a)  Justify the small step-size theory of Section 6.4, dealing with the infinite-precision LMS algorithm.  (b) How can stalling be prevented in the RLS algorithm? Suggest an appropriate method for stabilizing a digital implementation of the LMS algorithm whose leakage factor (1 − ma) in Eq. (12.19) has the equivalent effect of adding a white-noise sequence of zero mean and variance a to the input process u(n). Derive the formula to prevent the RLS algorithm from stalling due to digital effects by making the digital residual error eD(m) as small as possible.

14) Illustrate the assumptions in a statistical analysis of the finite-precision LMS algorithm.  Show that the total output mean-square error produced in the finite-precision algorithm has a steady-state composition. How can a leaky LMS algorithm be prevented from stalling due to digital effects? The error-propagation model of RLS algorithms considered in this chapter examines the “linearized” round-off propagation mechanism and focuses on the property of exponential stability. In reality, however, round-off error propagation in an RLS algorithm is a nonlinear mechanism. Explain.
