We use data from pooled 2000-2004 Current Population Surveys to examine generational differences in cohabitation and marriage among men and women ages 20-34 in the U.S. Consistent with our expectation and in line with assimilation theory, levels of cohabitation rise across succeeding generations. In contrast, generational differences in marriage follow a curvilinear pattern such that those in t...

the present article investigates the stress pattern system of central sarawani balochi (csb), spoken in sarawan located in sistan and baluchestan province of the islamic republic of iran, based on metrical theory as developed in hayes (1995). correspondingly, the present research illustrates the position of primary and secondary stress in mono-morphemic words, verbal paradigms, compound words, ...

Recent theories of lightness perception assume that lightness (perceived reflectance) is computed by a process that contrasts the target's luminance with that of one or more regions in its spatial surround. A challenge for any such theory is the phenomenon of lightness assimilation, which occurs when increasing the luminance of a surround region increases the target lightness: the opposite of c...

Physical and functional properties of foliage were measured at a variety of microsites in a broad-leaved Nothofagus fusca (Hook. f.) Ørst. canopy. The light climate of the foliage at these sites was monitored for 39 days in the late spring and early summer with in situ sensors. Foliage nitrogen content (N), mean leaf angle, and gas exchange characteristics were all correlated with the amount of...

Innovation researchers have known for some time that it is possible for a new technology to be widely acquired but only sparsely deployed among acquiring firms. When this happens, the observed pattern of cumulative adoptions will vary depending on which event in the assimilation process (i.e., acquisition or deployment) is treated as the adoption event. Instead of mirroring one another, a widen...

Acid metabolism and gas exchange studies were conducted in situ on the cactus Opuntia basilaris Engelm. and Bigel. A pattern of significant seasonal variation was evident. The pattern was controlled by rainfall, which significantly influenced plant water potentials, total gas transfer resistances, and nocturnal organic acid synthesis. In winter and early spring, when plant water stress was mild...

A complete ensemble data assimilation algorithm can be composed into three basic computational tasks: advancing an ensemble of model forecasts, computing ensembles of forward operators for available observations, and assimilating the observations to modify the ensemble of model states. Each of these tasks requires a fundamentally different pattern of communication when implemented on current ge...

Innovation researchers have known for some time that a new information technology may be widely acquired, but then only sparsely deployed among acquiring firms. When this happens, the observed pattern of cumulative adoptions will vary depending on which event in the assimilation process (i.e., acquisition or deployment) is treated as the adoption event. Instead of mirroring one another, a widen...
