Final answer:
Joanne follows a set of standards that refers to ethics, which is the discipline focused on establishing principles of right and wrong behavior. Codes of ethics are issued by institutions to guide the behavior of their members, and ethics is divided into metaethics, normative ethics, and applied ethics, with normative ethics setting norms for moral conduct.
Step-by-step explanation:
Joanne follows a set of standards for what is right and wrong in her conduct. This set of standards refers to ethics. Ethics is a discipline created to establish principles of the good and those of right behavior. It deals with the basic principles that serve as the basis for moral rules. Different principles will produce different rules, and when discussing these standards in relation to institutions, professions, or businesses, they may issue codes of ethics to guide the behavior of their members. In the broader sense, ethics is the field of philosophy that systematizes, defends, and recommends concepts of right and wrong behavior, divided into areas such as metaethics, normative ethics, and applied ethics. Normative ethics is particularly concerned with establishing norms and standards of moral conduct to guide our behavior effectively.
Therefore, when considering the question about what Joanne follows, laws, policies, and practices are different frameworks that could guide behavior but are not specifically focused on principles of right and wrong. In contrast, ethics specifically investigates morality and engages in recommending concepts of right and wrong behavior.
