This chapter focuses on women, who are HIV positive, from a global perspective. It illustrates more easily what makes groups of people, and in this case women, vulnerable and then consider vulnerability from a global health (GH) perspective using the chronic illness, HIV. The chapter presents some examples of situations that make women vulnerable to HIV and, once infected, vulnerable for life, and use a case-based approach to highlight women as a vulnerable population. It also focuses on the real ethical issues that occurred with each case, which one anticipate will help prepare the new GH nurse for practice in the global environment. The chapter demonstrates by using an exemplar of HIV-positive women, vulnerable populations exist both within and outside the United States. Reasons for vulnerability may include stigma, victimization, mental illness, migration, limited access to needed health care or food, or substance use.

This chapter addresses the key principles of sport, exercise, and performance psychology. It reflects the broadening of sport psychology studies to encompass more widespread human performance research. It provides Dr. Sachs’s honest and open remarks along with interspersed additions from the authors to introduce the field and its accompanying issues. In explaining his career trajectory, Dr. Sachs recalls earning his undergraduate degree in psychology and then applying to graduate programs in applied behavioral analysis. Dr. Sachs’s somewhat zigzagged trajectory in the field demonstrates the important sport and exercise psychology principle that explains the benefits of focusing on the process rather than the outcome when setting goals. Dr. Sachs added that the United States leads the way in research and writing with regard to sport and exercise psychology, while other countries may be more advanced in the application of that knowledge at the professional levels.
This chapter addresses the key principles of sport, exercise, and performance psychology. It reflects the broadening of sport psychology studies to encompass more widespread human performance research. The topic of decision making has been covered in psychology, economics, and motor learning but addressed very sparsely in sport, exercise, and performance psychology. Rational decision making requires defining the problem, identifying criteria, weighing those criteria, generating alternative solutions, and ultimately computing the optimal decision. The chapter introduces the literature on decision making and provides examples of factors that influence the choices people make. The decision to act, move, or what move to make is decided in the response selection stage, and the final stage is when one’s brain and muscles are organized to make the actual move. The key to improve the decision-making over time is to increase personal awareness of own limitations and keep learning and collecting information from reliable sources.
One of the most important findings from the original battered woman syndrome (BWS) research was the existence of a three-phase cycle of violence that could be described and measured through careful questioning of the battered woman. This chapter describes the cycle, updates it by adding information from the courtship period, and divides the third phase into several different sections where appropriate so that there may not be any loving contrition or even respites from the abuse at times during the relationship. Teaching the woman how her perception of tension and danger rises to an acute battering incident after which she experiences feelings of relief and then gets seduced back into the relationship by the batterer’s loving behavior, often similar to what she experienced during the courtship period, has been found to be helpful in breaking the cycle of violence that keeps the woman in the relationship.Source:
This chapter presents the anatomy review of the human heart. The human heart is a hollow four-chambered muscle that is responsible for pumping blood throughout the body. The heart lies in the mediastinum in the thorax, pointing toward the left of the midline. The heart consists of four main layers: the pericardium, epicardium, myocardium, and endocardium. The epicardium is the outermost layer of the heart muscle. The middle layer of the heart is called the myocardium. The innermost layer of the heart is the endocardium. The heart is divided into right and the left side. The right side of the heart contains the right atrium and right ventricle. The left side of the heart contains the left atrium and left ventricle. The heart has four valves: tricuspid valve, mitral valve, aortic valve, pulmonary valve; acting as tiny doors that keep the blood moving in one direction.
The chapter explores how to measure the electrical direction for the P wave, the QRS complex, and the T wave, as well as for other forces. It provides a method for determining the direction of the electrical force for any of these waves, or complexes, on the electrocardiograph (EKG). The heart produces electrical and mechanical energy on a continuous basis. Both forms of energy come from specialized cardiac muscle fibers. These fibers provide electrical signals and mechanical energy that physically pumps the blood. Although the EKG does not show that mechanical energy, it can be used to measure a variety of electrical events. When a force is abnormal in size or direction, it may indicate that the specific part of the heart producing the force is abnormal. Therefore, learning the normal electrical direction of forces in the heart provides a simple and scientific way of understanding and interpreting an EKG.
This chapter explains various types of heart blocks such as premature atrial contraction, sinus arrest and asystole. It explains various types of pacemakers such as ventricular pacemaker and artrial pacemakers. Junctional rhythm is a regular rhythm. A P wave is frequently not seen because the rhythm originates in the AV junctional node. Junctional rhythm may be a manifestation of digitalis toxicity, sick sinus syndrome, and acute inferior wall infarction. Pauses are most commonly caused by premature atrial contractions (PACs) that do not conduct down to the ventricle and generate a QRS complex. These are called nonconducted PACs (NCPACs). Asystole is a prolonged period of no electrical activity. Cessation of function of the sinus node is called sinus arrest. Normally, when sinus arrest occurs, another pacemaker must take over, such as the junction or the ventricles. Ventricular pacemaker rhythm demonstrates a vertical electrical artifact (EA) at the beginning of the QRS.
This chapter presents the case examples of pressure and volume overload on the left ventricle and provides list of criteria for the diagnosis of Left Ventricular Hypertrophy (LVH) on the electrocardiogram (EKG). It also describes and explains how to identify ST changes in LVH and LVH simulating anterior wall infarction on the EKG. LVH refers to an increase in the wall thickness or dilation of the left ventricle. LVH is often the result of increased pressure, or volume, within the left ventricular chamber. Mitral regurgitation (MR) occurs when the mitral valve allows the backflow of blood from the left ventricle into the left atrium. The most common cause of pressure overload is hypertension (HTN). Hypertrophy of the left ventricle increases the amplitude of the left ventricular forces, because more mass generates more electricity. In LVH, the frontal plane, the horizontal plane, or both may show increased QRS amplitude.

This chapter demonstrates how social work ethics apply to ethical and legal decision making in forensic social work practice. It discusses the context of social work practice in legal systems. The chapter also details the basic structures of the United States (U.S.) civil and criminal legal systems. It lays the foundation for the criminal and civil court processes in the United States and introduces basic terminology and a description of associated activities and progression through these systems. The chapter focuses on providing an introductory, and overarching, picture of both civil and criminal law in the U.S. and introduces the roles social workers play in these systems. It focuses on the ETHICA model of ethical decision making as a resource and tool that can be used to help forensic social workers process difficult and complex situations across multiple systems.
