52. Destroying self-esteem is an easy way to dominate others. Behind these trends that tend to level our world, there flourish powerful interests that take advantage of such low self-esteem, while attempting, through the media and networks, to create a new culture in the service of the elite. This plays into the opportunism of financial speculators and raiders, and the poor always end up the losers. Then too, ignoring the culture of their people has led to the inability of many political leaders to devise an effective development plan that could be freely accepted and sustained over time.
286. In these pages of reflection on universal fraternity, I felt inspired particularly by Saint Francis of Assisi, but also by others of our brothers and sisters who are not Catholics: Martin Luther King, Desmond Tutu, Mahatma Gandhi and many more. Yet I would like to conclude by mentioning another person of deep faith who, drawing upon his intense experience of God, made a journey of transformation towards feeling a brother to all. I am speaking of Blessed Charles de Foucauld.

An adjunct to the ISO paper sizes, particularly the A series, are the technical drawing line widths specified in ISO 128. For example, line type A ("Continuous - thick", used for "visible outlines") has a standard thickness of 0.7 mm on an A0-sized sheet, 0.5 mm on an A1 sheet, and 0.35 mm on A2, A3, or A4.[10]
The earlier DIN 6775 standard upon which ISO 9175-1 is based also specified a term and symbol for easy identification of pens and drawing templates compatible with the standard, called Micronorm, which may still be found on some technical drafting equipment.
Solar flood lights require ample sunlight to charge, usually 6 to 8 hours for a full charge. Once charged, the battery will power the light for 3 to 8 hours, depending on whether the flood light runs continuously or turns on only when it detects motion. Dusk-to-dawn solar lights require large-capacity batteries. They also usually have oversize solar panels, which enable them to draw and store as much solar energy as possible during the day so they can remain on all night long.
The testing process involved mounting the lights on a non-moving object, such as a building or a tree, and noting how easy it was to install. Again, points were given for straightforward installation and whether all the supplies needed for installation were included in the package.
The Adam Clayton Powell, Jr. State Office Building, named in honor of the first black congressman from New York, is located in the heart of Harlem in New York City. The facility is a nineteen story highrise office building located on 125th street and stands as the tallest building in Harlem. This state-owned facility also plays a central role in the community and acts as the center for many public and private events and activities, including meetings, charitable events, health screening clinics, and numerous other outreach events. Each summer, a series of free concerts are held on the outdoor plaza.
Parking: Visitors to the Adam Clayton Powell, Jr. State Office Building may park at any available parking spaces on the streets surrounding the facility. There is also paid parking at the Impark Parking Lot, located next to the facility on 126th Street.
Air driven pumps are non-arcing and non-sparking, and can be used safely in confined areas. When compared to other air driven pumps, Sprague Products pumps do the same job, but with fewer parts and seals for easy maintenance.

This handbook has been prepared to provide guidance to lighting designers and State, city, and town officials concerning the design and application of roadway lighting. It is not intended to be a detailed design guide. It is primarily a resource for policy makers and the design and construction community to evaluate potential need, benefits, and applicable references when considering a roadway or street lighting system. Documents available from organizations such as the American Association of State Highway and Transportation Officials (AASHTO), the Illuminating Engineering Society (IES), and the Commission Internationale de l'Eclairage (CIE) offer recommendations on lighting levels, lighting configurations, and other considerations. This handbook directs users to that information where applicable, and provide supplemental information on topics not addressed in those documents.
On a fundamental level, driving is largely a visual task. Being able to adequately see the road/street ahead and observe conflicting traffic and the behavior of other highway users is integral to the driving task. Lighting significantly improves the visibility of the roadway, increases sight distance, and makes roadside obstacles more noticeable to the driver, and therefore more avoidable.
Many factors influence our ability to see an object while driving. These include the contrast of the object, both photometric and color (i.e., the difference between the object and its background); the driver's adaptation level (impacted by the brightness of the road and surrounds, how much glare is present from approaching vehicles and luminaires, etc.), and how long the driver has to view a hazard. Understanding these factors is vitally important to developing an effective design for roadway and street lighting.
The presence of extraneous light in the field of view may cause a nuisance or distraction to the driver, independent of the effects of disability and discomfort. Bright light sources tend to cause distraction, and the eye may be drawn to them. Lighting that is used for advertising, for example, may cause visual clutter and add complexity to the scene, making the driving task more challenging. There is no defined method or measurement system for assessing nuisance glare.
The results of the model recommended by Rea (15) show an impact of using higher S/P ratio sources of moderate impact for most recommended roadway lighting levels with no difference in the visual efficacy multiplier for levels freeway lighting levels of around 0.6 cd/m2 and more significant difference of over 20% for the lowest recommended lighting level streets like low pedestrian volume residential designed to 0.3 cd/m2.
Illuminance is the amount of light that falls onto a surface. Illuminance is measured as the amount of lumens per unit area either in footcandles (lumens/ft2) or in lux (lumens/m2). Illuminance is variable by the square of the distance from the source. As a lighting metric, illuminance is simple to calculate and measure, not needing to take into account the reflection properties of the roadway surface and only requiring a fairly inexpensive illuminance meter for field verification. The drawback to this metric is that the amount of luminous flux reaching a surface is often not indicative of how bright a surface will be or how well a person can see.
The Transportation Association of Canada Guide for the Design of Roadway Lighting includes a warranting system for intersection lighting. The warranting system is based on geometric, operational, environmental and crash factors. The critical factors determining the need for illumination are traffic volumes and night-time crashes. The warrant point score indicates whether full intersection lighting, partial lighting or delineation lighting is needed. Full intersection lighting denotes illumination covering an intersection in a uniform manner over the traveled portion of the roadway. Partial lighting is the illumination of key decision areas, potential conflict points, and/or hazards in and on the approach to an intersection. The illumination of vehicles on a cross street or median crossing, or lighting that marks an intersection location for approaching traffic, is referred to as sentry or delineation lighting.
Some authorities have looked at simple ways to prioritize lighting needs, particularly with rural intersections. Preston and Schoenecker (1999) (16) developed a system using traffic volumes on the major street by functional classification to give a priority to lighting intersections.
Research reported in the Journal of Carcinogenesis (18) regarding the impact of light at night on residents from street lighting systems notes: "These light levels rarely exceed 10 lux at the cornea outdoors. Indoors, behind closed curtains, the levels would likely to be much lower. Further, the human eyelids transmit only about 1% to 3% in the short wavelength region of the visible spectrum... Given the available published data on human melatonin suppression in response to light, light trespass through residential windows is an unlikely cause of melatonin suppression, simply because the light levels are so low, particularly with the eyes closed."
To lay out poles, the designer must undertake lighting calculations to define optimal pole spacing. Once maximum pole spacing is defined, one can lay out poles on the road drawings using a calculator and scale rule. The design should lay out poles locating a pole at a start points such as cross street, then spacing the poles evenly within the maximum pole spacing defined by the calculations, as shown in Figure 32. The pole spacing may need to be adjusted to suit driveways and utility conflicts.
Lighting levels are established by applying criteria based on road classification(arterial, local, collector), type of pavement, pedestrian activity/conflict level. The higher the level of pedestrian conflict, the higher the level of lighting recommended. The present design practice is to use the highest pedestrian conflict/activity level for an area or segment of roadway to establish the minimum lighting levels for the portion of roadway under consideration. Once the minimum level of lighting is established, street lights have traditionally provided that level of lighting throughout the hours of darkness as adaptive technologies have been unavailable. 2ff7e9595c
