Romantic relationships among emerging adults (individuals aged 18–25 years) are typically homogenously classified both theoretically and empirically as ‘‘exploratory’’ and ‘‘unstable.’’ With a sample of college students (N 1⁄4 340), we examined within-group variation among romantic relationships in emerging adulthood using latent class analyses. Four predictor variables indicated four types of ...

is finite, and that K(1) = 1, K(2) = 2. For k > 2, Favard gives no quantitative information about K(k). An estimate for the supremum under the additional restriction that only uniform t be considered can be found in Jerome and Schumaker [5]. Their argument was extended by Golomb [4] as far as it will go, viz., to include nonuniform t’s whose global mesh ratio Rt := maxi ∆ti/mini ∆ti is bounded....

We shall take it as known that a polynomial of degree n has at most n distinct zeros (a proof is given in Lemma 1 below). Given n+1 distinct real numbers xj and any numbers αj (0 ≤ j ≤ n), there is a unique polynomial p of degree at most n satisfying p(xj) = αj (0 ≤ j ≤ n). The polynomial is unique, since if p1 and p2 were two such polynomials, then p1−p2 would be zero at each xj: since it has ...

Many studies have documented a negative association between macroeconomic indicators and fertility in times of economic crisis. These studies are based on research designs that do not allow for excluding that the observed association is driven by confounders. The aim of the present paper is to estimate the causal effect of the Great Recession on cohorts’ childlessness in the United States. We a...

This study examined factors related to word list performance predictions made by younger and older adults. A performance prediction is an estimate made prior to being exposed to the material that is studied for a specific task. The current study examined the age differences in a sample of 59 older adults (M = 76.83 years old, SD = 8.28) and 51 younger adults (M = 21.19 years old, SD = 3.22) on ...

In this paper, we present our recent work in the analysis and modeling of speech under dialect. Dialect and accent significantly influence automatic speech recognition performance, and therefore it is critical to detect and classify non-native speech. In this study, we consider three areas that include: (i) prosodic structure (normalized f0, syllable rate, and sentence duration), (ii) phoneme a...

With the new realities of the digital age, print newspapers are experimenting with different pricing models for their online content. Using NYT’s paywall rollout as a natural experiment, our study finds that a firm’s information pricing policy influences the pattern and effectiveness of online word of mouth (WOM) in social media. Using difference-in-difference-indifferences analysis, we find th...

I examine whether financial reporting quality and credibility affect firm financing and investment decisions. I use PCAOB inspections of non-U.S. auditors as exogenous shocks to the reporting quality of non-U.S. firms audited by PCAOB inspected auditors. I then use the subsequent public revelation of the inspection as exogenous shocks to the reporting credibility of non-U.S. firms that employ P...

The study presented here relies on the integrated use of different kinds of knowledge in order to improve first-guess accuracy in non-word context-sensitive correction for general unrestricted texts. State of the art spelling correction systems, e.g. ispell, apart from detecting spelling errors, also assist the user by offering a set of candidate corrections that are close to the misspelled wor...

The absolute V light curves of 5 SNe Ia, selected to represent the known range of absolute luminosities at maximum for this class of objects, are presented. Comparison of the long term luminosity evolution shows that the differences seen at maximum persist, and actually increase with time, reinforcing the notion that intrinsic differences do exist among SNe Ia. Since such differences are not ac...
