This phenomenon is an automatic-response mechanism that activates even before a human becomes consciously aware that a startling, unexpected or unknown sound has been "heard". [2] That this vestigial response occurs even before becoming consciously aware of a startling noise would explain why the function of ear-perking had evolved in animals.
Health services research (HSR) became a burgeoning field in North America in the 1960s, when scientific information and policy deliberation began to coalesce. [1] Sometimes also referred to as health systems research or health policy and systems research (HPSR), HSR is a multidisciplinary scientific field that examines how people get access to health care practitioners and health care services ...
Combining political science with the study of public health, health politics aims to understand the unique interplay of politics within this policy domain to locate the politics of health. [ 15 ] "Among professionals in public health, the political system is commonly viewed as a subway's third rail: avoid touching it, lest you get burned.
