To illustrate the physical implications of (4), physicists tend to use two main types of examples: (i) examples that examine the mass and energy of a single body as an un-analyzed whole, and (ii) examples that examine the mass and energy of a collection of objects, especially, atomic and sub-atomic objects involved in collisions.
For example, a study that examined the patterns of depression treatment trends from 1998 through 2007 among all adults reported an antidepressant use of 75.3% in 2007 [ 26].
For example, a study that examined de novo (i.e., no previous conditioning) delay eyeblink conditioning (Sears et al., 1994) found that in high-functioning (average IQ > 100) autistics, the %CR fraction rose more rapidly than in controls, reaching close to a half-maximum after only two blocks of trials.
For example, another Australian study that examined the impacts of intervention research found moderate to high policy and practice impacts were scored in 10 out of 17 cases (59%) [ 9].
For example, in a study that examined depression management in 324 patients with diabetes (10), a collaborative care approach that involved a focus on patient preferences, tailoring of patients' care through outreach or extra telephone calls with a nurse case manager, and facilitation of communication between the patient and the primary care provider was compared with usual primary care.
For example, in a study that examined the relationship between maternal smoking during pregnancy and serum lipid, lipoprotein, and apolipoprotein levels in newborns (38 smoker and 42 non smoker mothers), babies of mothers who smoked during pregnancy showed significantly higher LDL/HDL ratios, along with CHO/HDL ratios (I can et al. 1997).
For example, studies that examine the risk for spontaneous abortions in women exposed to a drug during pregnancy are susceptible to immortal time bias because the chance of drug exposure increases the longer a pregnancy lasts.
For example, in a recent study that examined more than 6000 secondary students' interest in STEM careers, males expressed greater interest in engineering and maintained that interest throughout high school; females initially declared greater interest in medicine and health careers but reported lower levels of interest in STEM careers by the end of high school (Sadler et al. 2012).
For example, Zofia coauthored a paper that examined the apparent increase in metabolic syndrome in people with PTSD; this relationship might be related to the altered sympathetic reactivity associated with that disorder and the altered stress sensitivity (Rasmusson et al, 2010).
