National parks.
The two national parks at the falls are relatively small—Mosi-oa-Tunya National Park is and Victoria Falls National Park is .
However, next to the latter on the southern bank is the Zambezi National Park, extending west along the river.
Animals can move between the two Zimbabwean parks and can also reach Matetsi Safari Area, Kazuma Pan National Park and Hwange National Park to the south.
On the Zambian side, fences and the outskirts of Livingstone tend to confine most animals to the Mosi-oa-Tunya National Park.
In addition fences put up by lodges in response to crime restrict animal movement.
In 2004 a separate group of police called the Tourism Police was started.
They are commonly seen around the main tourist areas, and can be identified by their uniforms with yellow reflective bibs.
SFFD bunker/turnout gear is black with reflective stripes for all city ranks except for the fire chief who wears white.
Airport fire fighters wear tan.
SFFD Fire Reserve gear is tan or yellow for coats and black for pants.
Wildland turnout gear is yellow reflective.
Yellow reflective traffic safety vests are worn during street/highway emergency incidents (except during firefighting or hazmat activities). 
  For the eighth successive season, the race victory gives 50 points, a 2nd place gives 46 pts, a 3rd place 43 pts, a 4th place 40 pts, a fifth place 37 pts, a 6th place 34 pts, then further decreasing by two pts down to the 15th place (16 pts), then linearly decreasing by one point down to the 30th place (see the Place/Points table on the page's upper right).
Equal placings, i.e.
same-time finishes (ties) give an equal number of points.
The sum of all WC points of the season, minus the score from a predetermined number of events (say, 3) give the biathlete's accumulated WC score (naturally, the races chosen to be eliminated from the total will be those with the lowest scores).
Biathletes with an equal number of accumulated points are ranked by number of victories, 2nd places, 3rd places, and so on, in practice reducing the possibility of ties to just about nil.
In addition to the Total WC score as described above, the points from races in each separate single-biathlete format—Individual, Sprint, Pursuit, and Mass start—accumulate toward separate scores with associated "sub-Cups" to be won.
See the main Biathlon article for a detailed description of the race formats.
In any given race, the biathlete with the highest accumulated Total WC score before the race wears a yellow number bib.
The leader of the specific race format wears a red bib.
If the same biathlete leads both the Total and the specific format's World Cup, a combined yellow-and-red bib is worn.
In the first races of the season, the winners of the previous season's Cups wear the associated bibs.
There are also two multi-biathlete Cups to be won, namely the Relay and Nation Cups.
The scores of the Relay races are awarded to each nation's team in the same manner as in the single-biathlete Cups.
No leader bibs are worn during the Relays.
For the Nation Cup, the combined scores of the three best biathletes from each nation in the Individual and Sprint races, as well as the Relay scores, are accumulated.
The Nation Cup points scale is different from the World Cup points scale; each place from 1st through 30th scores 100 more points than in the World Cup, and from 31st down to 130th points are awarded on a scale from 100 to 1.  
  For the seventh successive season, the race victory gives 50 points, a 2nd place gives 46 pts, a 3rd place 43 pts, a 4th place 40 pts, a fifth place 37 pts, a 6th place 34 pts, then further decreasing by two pts down to the 15th place (16 pts), then linearly decreasing by one point down to the 30th place (see the Place/Points table on the page's upper right).

Biographical Information Blank (BIB) is a type of assessment that uses biodata in employee recruitment to help determine which of several candidates should be hired for a job.
Originally companies would take the information from their job applications forms to see what would be useful in predicting the job performance of employees.
Over time the amount and type of biographical information collected expanded and was put into the BIB assessments we find today.
The modern BIB is a self-report instrument that includes questions about past personal and work experiences, as well as interests, opinions, values and attitudes.
Its items are all presented in the multiple choice format.
The emphasis is on past behaviors because they are best predictors of future behaviors.
Typically, BIBs are designed to predict success in a particular job because they contribute to a predictor sample, which is used to make personnel selection decisions.
There are two types of BIBs: the empirical and the rational.
With the empirical BIB, each item is correlated with a measure of job performance or other criterion of job success.
Those items that can predict job success are retained for the BIB.
The rationale approach is to start with a job analysis to determine the knowledge, skill, ability, and other job characteristics (KSAOs) needed for the job.
Items are chosen that reflect the required KSAOs.
A great deal of research has shown that BIBs are able to predict job success.
Both types of BIBs, the empirical and the rational seem to work equally well.
