Federal Holidays: Evolution and Current Practices

[Excerpt] Since 1870, numerous proposals have been introduced in Congress to establish permanent federal holidays. Only 11, however, have thus far become law. Although these patriotic celebrations are frequently referred to as “national holidays,” legally they are only applicable to federal employees and the District of Columbia. Neither Congress nor the President has asserted the authority to declare a “national holiday” that would be binding on the 50 states, as each state individually determines its legal holidays. Creating a holiday for federal employees does, however, affect each state in a variety of ways, including the delivery of mail and conduct of business with federal agencies. Federal holidays have been created for a number of reasons. In several instances, Congress created federal holidays after a sizeable number of states created state holidays. In other instances, Congress took the lead. Additionally, each holiday was designed to emphasize a particular aspect of American heritage or to celebrate an event in American history. particular aspect of American heritage or to celebrate an event in American history

The Contribution of Wide Range of Space and Time Scales to the Northward Flux of Westerly Momentum

The contribution of a wide range of time scales to the long time average of atmospheric variances and covariances, and in particular on the contribution of the annual cycle is discussed. The interannual variability of seasonally averaged fluxes is analyzed in the same context. For definiteness, numerical results will be shown for the eddy momentum flux at 200 mb as obtained from seven years of NMC analyses (March 8, 1970 - March 10, 1977). The role of the seasonal cycle is considered

Conservation laws of wave action and potential enstrophy for Rossby waves in a stratified atmosphere

The evolution of wave energy, enstrophy, and wave motion for atmospheric Rossby waves in a variable mean flow are discussed from a theoretical and pedagogic standpoint. In the absence of mean flow gradients, the wave energy density satisfies a local conservation law, with the appropriate flow velocity being the group velocity. In the presence of mean flow variations, wave energy is not conserved, but wave action is, provided the mean flow is independent of longitude. Wave enstrophy is conserved for arbitrary variations of the mean flow. Connections with Eliassen-Palm flux are also discussed

Spankers and Nonspankers: Where They Get Information on Spanking

Because spanking is common, puts children at risk for harmful side effects, and is ineffective as a positive behavior management tool, it is important to identify the kind of advice families receive about the appropriateness of spanking. Using the health belief model, I examined spankers and nonspankers on the spanking messages they received from eight sources of discipline information and how important they perceived these messages to be. Data from telephone interviews with 998 mothers with children aged 2 to 14 years showed that 33% of mothers rated advice from workshops, pediatricians, newspapers and magazines, and books as ‘‘very important.’’ Less than 15% rated parents and relatives and friends as such. Spankers perceived sources as recommending spanking, whereas nonspankers perceived sources as opposing spanking. Mothers were more likely to spank when they perceived more intense messages to spank, less intense messages opposing spanking, had younger children, and were of lower socioeconomic status

Adaptive and maladaptive personality traits as predictors of violent and nonviolent offending behavior in men and women

he aim of this study was to assess both violent and nonviolent offending behavior in a single, mixed-sex population. The rationale for this is that the two types of offending are usually researched separately, despite evidence that they overlap. A comprehensive measure of general violence, intimate partner violence (IPV), and nonviolent offending behavior was administered to 116 men and 181 women, together with measures of personality and personality disorder (PD) traits, to investigate whether predictors of violent and nonviolent offending were similar or different for men and women. Men were found to perpetrate higher levels of general violence and nonviolent offenses than women, but women perpetrated significantly more IPV than men. Cluster B PD traits predicted all three offense types for women and also men's general violence and nonviolent offending. Women's general violence and men's non-violence also had one unique risk factor each, low agreeableness, and low conscientiousness, respectively. The main difference was for IPV, where men's IPV was predicted by cluster A PD traits, indicating that men's and women's risk factors for IPV may be different, although their risk factors for the other offense types were fairly consistent

The seasonal cycle of energetics from the GLAS/UMD climate GCM

The annual cycle of atmospheric energetics from a 2-year integration of the GLAS/UMD Climate GCM is computed and compared to results from the European Centre analyses of the GWE year, and to previously published results on a global basis. All calculations are done in the mixed space-time domain. The main conclusions are: (1) the seasonal cycle of today's eddy kinetic energy (in both hemispheres), and of the transient eddy available potential energy and the potential-to-kinetic energy conversions (mean and eddy) in the Northern Hemisphere are well simulated by the GCM; (2) the GCM's tendency to have anomalously large mean u-winds at upper levels in high latitudes leads to excessive wintertime values of mean kinetic and available potential energies, and causes distortions in the GCM latitude-height distribution of kinetic energy and of many of the conversions; (3) the eddy conversion of available potential-to-kinetic energy obtained from the ageostrophic wind in these analyses; and (4) the conversions in the Southern Hemisphere are not well simulated by the GCM, although the observations are somewhat questionable

The aurora as a source of planetary-scale waves in the middle atmosphere

Photographs of global-scale auroral forms taken by scanning radiometers onboard U.S. Air Force weather satellites in 1972 show that auroral bands exhibit well-organized wave motion with typical zonal wave number of 5 or so. The scale size of these waves is in agreement with that of well-organized neutral wind fields measured by the 1967-50B satellite in the 150- to 220-km region during the geomagnetic storm of May 27, 1967. The horizontal scale size revealed by these observations is in agreement with that of high-altitude traveling ionospheric disturbances. It is conjectured that the geomagnetic storm is a source of planetary and synoptic scale neutral atmospheric waves in the middle atmosphere. The possible existence of a source of waves of the proper scale size to trigger instabilities in middle atmospheric circulation systems may be significant in the study of lower atmospheric response to geomagnetic activity
