doleac has also written on issues related to contemporary crime control, such as the use of dna databases to deter and capture criminals, as well as the role of outside lighting. her work on lighting with nicholas j. sanders used a 2007 natural experiment where congress increased daylight savings time by four weeks. they added three weeks in the spring and one week in the fall. doleac and sanders used this as an opportunity to study the effect that daylight, separate from other seasonal factors, might have on crime, and found that when daylight savings time began in the spring, robbery rates for the entire fell 7 percent with an additional 27 percent drop during the evening hour that gained extra sunlight. this study is relevant for broader consideration in crime control that focuses on expanding lighting to high crime areas with external lighting.

as explained by richard meade in the english journal of the (american) national council of teachers of english, the form "daylight savings time" (with an "s") was already in 1978 much more common than the older form "daylight saving time" in american english ("the change has been virtually accomplished"). nevertheless, even dictionaries such as merriam-webster's, american heritage, and oxford, which describe actual usage instead of prescribing outdated usage (and therefore also list the newer form), still list the older form first. this is because the older form is still very common in print and preferred by many editors. ("although "daylight saving time" is considered correct, "daylight savings time" (with an "s") is commonly used.") the first two words are sometimes hyphenated ("daylight-saving(s) time"). merriam-webster's also lists the forms daylight saving (without "time"), daylight savings (without "time"), and daylight time. the oxford dictionary of american usage and style explains the development and current situation as follows: "although the singular form "daylight saving time" is the original one, dating from the early 20th century—and is preferred by some usage critics—the plural form is now extremely common in ame. [...] the rise of "daylight savings time" appears to have resulted from the avoidance of a miscue: when "saving" is used, readers might puzzle momentarily over whether "saving" is a gerund (the saving of daylight) or a participle (the time for saving). [...] using "savings" as the adjective—as in "savings account" or "savings bond"—makes perfect sense. more than that, it ought to be accepted as the better form."
