We hypothesized that the in- and out degree centralities of natural-resource occupations would decline with increasing socioeconomic development, hence implying that not only fewer households engage in such occupations, but rather that fewer households engage in these occupations while simultaneously working with something else.
A lot of data supports the fact that technological advances actually create jobs — eliminating dull and low-skill occupations, while simultaneously creating entirely new categories of work.
The choice of occupation is made simultaneously with human capital investments so as to maximize expected lifetime earnings.
For red deer, encounters of < 50 m, encounters of > 50 m and non-simultaneously occupation of the same area were observed most frequently with cattle, and 5% of the game wardens reported physical contact between the two species.
The segregation of turning movements by partial control and the presence of mini roundabout at Intersection B can enhance maneuver ability of vehicles, but simultaneously increase the occupation time of straight through movements at Intersection B. .
The segregation of turning movements by partial control and the presence of mini roundabout at Intersection B can enhance maneuver ability of vehicles, but simultaneously increase the occupation time of straight through movements at Intersection B. The proposed methodology will be useful to determine the occupation time for various movements at unsignalized intersections.
However, previous findings have suggested that women often postpone diagnostics and prevention procedures because of their family duties (e.g., taking care of their children, housekeeping, and simultaneously maintaining an occupation or career) [ 23, 24].
Therefore, occupation-related risk factors were simultaneously raised, and a case cohort study showed a higher brain tumor incidence in female textile workers during that period in Shanghai [ 26].
Numerical results show that the proposed approach is effective in saving the bandwidth occupation and maintaining the measurement accuracy simultaneously.
For the IV results, it reports coefficient estimates of the impact of Mexican immigrants from a first-stage occupation model which uses both instruments simultaneously (column 4), and then for two separate first-stage occupation models, each using one instrument, respectively (columns 5 and 6).
