People tend to contribute more to a charity when they are asked to. Although this so-called ‘power of asking’ is well-known among fundraisers, the existing literature does not pay much attention to the role of donation requests in charitable giving. This paper uses a unique data set, which was designed to measure giving behavior in the United States, to estimate the causal effects of charitable...

In order to investigate the dynamic properties of the flux line lattice, the temperature dependencies of the basic and Ž . higher harmonic complex AC susceptibilities have been analysed. In particular, the first i.e., fundamental and the third Ž . X Ž . Y Ž . harmonic x T sx T q ix T , have been measured at different frequencies, and the measurements have been 1,3 1,3 1,3 compared with both ana...

In this paper a novel method based on evolutionary algorithms is presented to estimate the harmonic components. In general, the optimization of the harmonic estimation process is a multi-component problem, in which evaluation of the phase and harmonic frequency is the nonlinear part of the problem and is solved based on the mathematical and evolutionary methods; while estimation of amplitude of...

background one common challenge to social systems is achieving equity in financial contributions and preventing financial loss. because of the large and unpredictable nature of some costs, achieving this goal in the health system presents important and unique problems. the present study investigated the household financial contributions (hfcs) to the health system.   methods the study investiga...

The results of harmonic and anharmonic frequency calculations on a guanine-cytosine complex with an enolic structure (a tautomeric form with cytosine in the enol form and with a hydrogen at the 7-position on guanine) are presented and compared to gas-phase IR-UV double resonance spectral data. Harmonic frequencies were obtained at the RI-MP2/cc-pVDZ, RI-MP2/TZVPP, and semiempirical PM3 levels o...

IN TONAL MUSIC, PATTERNS OF TENSION AND resolution form one of the core principles evoking emotions. The experience of musical tension and resolution depends on various features of the music (e.g., dynamics, agogics, melody, and harmony); however, the relative contribution of different features to the experience of tension is less clear. To investigate the influence of different features on sub...

Second-harmonic scattering experiments of water and other bulk molecular liquids have long been assumed to be insensitive to interactions between the molecules. The measured intensity is generally thought to arise from incoherent scattering due to individual molecules. We introduce a method to compute the second-harmonic scattering pattern of molecular liquids directly from atomistic computer s...

The 3α Faddeev equation using 2α RGM kernel involves redundant components whose contribution to the total wave function completely cancels out. We propose a practical method to solve this Faddeev equation, by eliminating the admixture of such redundant components. A complete equivalence between the present Faddeev approach and a variational approach using the translationally invariant harmonic-...

We calculate the cross-section for the excitation and subsequent decay of triple giant resonances (TGDR) in several nuclei excited with heavy ions. The recently developed coherent plus incoherent theory for the excitation in conjunction with the hybrid decay model of Dias-Hussein-Adhikari are used for the purpose. It is emphasized that the direct decay of the TGR is expected to deviate apprecia...
