How effective are the things people say to apologize? Effects of the realization of the apology speech act.

The Cross-Cultural Speech Act Realization Project (Blum-Kulka, House, & Kasper, 1989a) has identified five components of an apology speech act set : five strategies that speakers use to apologize. This study examines the effects of four of those strategies (illocutionary force indicating device, expression of responsibility, promise of forebearance, and offer of repair) on the judgments made by hearers about the speaker and about the apology. Each of the strategies is shown to have an independent effect in improving reactions to the speaker. Further, the magnitude of these effects appear to be roughly similar for each of the strategies. The things people say to apologize do seem to be effective in accomplishing the self-presentational goals of apologizers

PROCRASTINATION, CONSCIENTIOUSNESS, ANXIETY, AND GOALS: EXPLORING THE MEASUREMENT AND CORRELATES OF PROCRASTINATION AMONG SCHOOL-AGED CHILDREN

We explore the reliability and validity of a self-report measure of procrastination and conscientiousness designed for use with third- to fifth-grade students. The responses of 120 students are compared with teacher and parent ratings of the student. Confirmatory and exploratory factor analyses were also used to examine the structure of the scale. Procrastination and conscientiousness are highly correlated (inversely); evidence suggests that procrastination and conscientiousness are aspects of the same construct. Procrastination and conscientiousness are correlated with the Physiological Anxiety subscale of the Revised Children’s Manifest Anxiety Scale, and with the Task (Mastery) and Avoidance (Task Aversiveness) subscales of Skaalvik’s (1997) Goal Orientation Scales. Both theoretical implications and implications for interventions are discussed

Distribution of Time-Averaged Observables for Weak Ergodicity Breaking

We find a general formula for the distribution of time-averaged observables for systems modeled according to the sub-diffusive continuous time random walk. For Gaussian random walks coupled to a thermal bath we recover ergodicity and Boltzmann's statistics, while for the anomalous subdiffusive case a weakly non-ergodic statistical mechanical framework is constructed, which is based on L\'evy's generalized central limit theorem. As an example we calculate the distribution of $\bar{X}$: the time average of the position of the particle, for unbiased and uniformly biased particles, and show that $\bar{X}$ exhibits large fluctuations compared with the ensemble average $$.Comment: 5 pages, 2 figure

Long-Tailed Trapping Times and Levy Flights in a Self-Organized Critical Granular System

We present a continuous time random walk model for the scale-invariant transport found in a self-organized critical rice pile [Christensen et al., Phys. Rev. Lett. 77, 107 (1996)]. From our analytical results it is shown that the dynamics of the experiment can be explained in terms of L\'evy flights for the grains and a long-tailed distribution of trapping times. Scaling relations for the exponents of these distributions are obtained. The predicted microscopic behavior is confirmed by means of a cellular automaton model.Comment: 4 pages, RevTex, includes 3 PostScript figures, submitted to Phys. Rev. Let

Non-perturbative scale evolution of four-fermion operators

We apply the Schroedinger Functional (SF) formalism to determine the renormalisation group running of four-fermion operators which appear in the effective weak Hamiltonian of the Standard Model. Our calculations are done using Wilson fermions and the parity-odd components of the operators. Preliminary results are presented for the operator $O_{VA}=(\bar s \gamma_\mu d)(\bar s \gamma_\mu \gamma_5 d)$.Comment: Lattice2002(improve

Transport Properties of Highly Aligned Polymer Light-Emitting-Diodes

We investigate hole transport in polymer light-emitting-diodes in which the emissive layer is made of liquid-crystalline polymer chains aligned perpendicular to the direction of transport. Calculations of the current as a function of time via a random-walk model show excellent qualitative agreement with experiments conducted on electroluminescent polyfluorene demonstrating non-dispersive hole transport. The current exhibits a constant plateau as the charge carriers move with a time-independent drift velocity, followed by a long tail when they reach the collecting electrode. Variation of the parameters within the model allows the investigation of the transition from non-dispersive to dispersive transport in highly aligned polymers. It turns out that large inter-chain hopping is required for non-dispersive hole transport and that structural disorder obstructs the propagation of holes through the polymer film.Comment: 4 pages, 5 figure

Relationship between Secondary Metabolites, Antiradical Activities, and Colour Characteristics of Cochlospermum Tinctorium A. Rich. (Bixaceae) Root

Cochlospermum tinctorium A. Rich. (Bixaceae) is a widespread herbaceous plant in the African sahelian and soudanian zones. Its root is used as food and medicinal plant. Studies of secondary metabolites, functional activities and trichromatic parameters were realized according to standard methods of laboratory. At a threshold of α = 0.05, significant correlations (p < 0.05) were found between secondary metabolites contents and functional activities such as radical scavenging activity of antioxidant component or hydroxyl radical scavenging activity. The value of DPPHH was 95.56 ± 0.94% for CT inner Matrix with variation of 0.12% for CT Soaked inner Matrix and 1.63% for CT Peeler. But HSRA was 37.14 ± 5.71 for CT inner Matrix with variation of -38.46% for CT Soaked inner Matrix and -71.79% for CT Peeler. Cochlospermum tinctorium root has exhibited efficiency to heal many diseases thanks to multiple bioactive compounds. In addition, the colour of powders depended upon chemical compounds. Finally, Cochlospermum tinctorium root was found to neutralize organic radicals and reactive oxygen species

Linear and non linear response in the aging regime of the 1D trap model

We investigate the behaviour of the response function in the one dimensional trap model using scaling arguments that we confirm by numerical simulations. We study the average position of the random walk at time tw+t given that a small bias h is applied at time tw. Several scaling regimes are found, depending on the relative values of t, tw and h. Comparison with the diffusive motion in the absence of bias allows us to show that the fluctuation dissipation relation is, in this case, valid even in the aging regime.Comment: 5 pages, 3 figures, 3 references adde

Electrical transport and percolation in magnetoresistive manganite / insulating oxide composites: case of La0.7Ca0.3MnO3 / Mn3O4

We report the results of electrical resistivity measurements carried out on well-sintered La0.7Ca0.3MnO3 / Mn3O4 composite samples with almost constant composition of the magnetoresistive manganite phase (La0.7Ca0.3MnO3). A percolation threshold (fc) occurs when the La0.7Ca0.3MnO3 volume fraction is ~ 0.19. The dependence of the electrical resistivity as a function of La0.7Ca0.3MnO3 volume fraction (fLCMO) can be described by percolation-like phenomenological equations. Fitting the conducting regime (fLCMO > fc) by the percolation power law returns a critical exponent t value of 2.0 +/- 0.2 at room temperature and 2.6 +/-0.2 at 5 K. The increase of t is ascribed to the influence of the grain boundaries on the electrical conduction process at low temperature.Comment: 7 pages, 3 figures, accepted for publication in Phys. Rev.
