The following principles are seen to operate in the rules Pānini provides for Sanskrit grammar.
- The obvious principle that the introduction of affixes and augments which condition sound replacements necessarily precede the latter.
- Bracketing, whereby an operation whose condition is internal relative to a condition causing another operation applies prior to the latter.
- The derivational prehistory of a form is pertinent to the operations which apply to it.
- Blocking: a rule R2 is said to block an R1 if, in a given domain, R1 tentatively applies (and would apply in the absence of R2) wherever R2 can apply, while R2 would be vacuous if R1 applied.
- Limited blocking, which obtains where R1 and R2 overlap but also have independent domains of application.

Professions are guided by codes of ethics to aid them in performance of their duties and to ensure maintenance of high standards of conduct. Police officers are faced with a maze of obligations in the performance of their official duties. The “Law Enforcement Code of Ethics” and “Canons of Police Ethics” were created to make explicit the conduct considered appropriate for police officers and to guide them in the performance of their duties.This study investigates how police officers in several police agencies view their professional ethics. Some of the broader questions examined in the study are the following: Do police officers have a clear understanding of the “Law Enforcement Code of Ethics” and the “Canons of Police Ethics?” Do they feel constrained by agency, societal, or other factors from behaving professionally? Do they consider their ethics adequate to guide professional conduct, and are they willing to abide by the principles? The responses indicate reliance on personal ethics in situations where standard police ethics are not clear, and suggest the need for further research in police ethics. 相似文献
