Park ranger
The duties of the modern park ranger are as varied and diverse as the parks where they serve and in recent years have become more highly specialized. Regardless of the regular duties of any one discipline, the goal of all rangers remains to protect the park resources for future generations and to protect park visitors. This goal is accomplished by the professionalism and sometimes overlapping of the different divisions. For example, an interpretive ranger may perform a law enforcement role by explaining special park regulations to visitors and encouraging them to be proper stewards of natural and cultural history. Law enforcement rangers and other park employees may contribute to the mission of the interpretive ranger by providing information to park visitors about park resources and facilities. The spirit of teamwork in accomplishing the mission of protecting the parks and people is underscored by the fact that in many cases, for the U.S. National Park Rangers in particular, all park rangers share a common uniform regardless of work assignment.The Adopt A Ranger Foundation has calculated that worldwide about 150,000 rangers are needed for the protected areas in developing and transitions countries. There is no data on how many rangers are employed at the moment, but probably less than half the protected areas in developing and transition countries have any rangers at all and those that have them are at least 50% short. This means that there would be a worldwide ranger deficit of 105,000 rangers in the developing and transition countries.
Parking meter
Some cities have gone to a device called a Parkulator, in which the users purchase a display device, usually for $5 or $10, then load it with as much time as they care to purchase. They then activate the device when they park at a location, and place the display device on their dashboard so it is visible from the front windshield. The device counts down the time remaining on the device while it remains activated. When they return, then the clock stops running, and the person does not overpay for time unused. In the UK, it is now possible to park and pay with credit or debit card through a dedicated telephone service. Civil Enforcement Officers that patrol the parking area are automatically informed through their handheld devices.
An In-Vehicle Parking Meter (IVPM) (also known as in-vehicle personal meter, in-car parking meter, or personal parking meter) is a handheld electronic device, the size of a pocket calculator, that drivers display in their car windows either as a parking permit or as proof of parking payment. Implementation of IVPM began in the late 1980s in Arlington, VA, and is spreading to campuses and municipalities worldwide as a centralized method of parking management, revenue collection, and compliance enforcement. There have since been similar adaptations including the Comet and SmartPark by Ganis Systems, EasyPark by Parx (a subsidiary of On Track Innovations), ParkMagic by ParkMagic Ireland, iPark by Epark, and AutoParq by Duncan Industries. Another technology offers the possibility of reloading money (parking time) to the device via a secure Internet site.People
