ADVERTISING AND PRODUCT TRIAL - THE EFFECT OF MESSAGE’S REGULATORY FOCUS AND PRODUCT TYPE ON CONSUMER EVALUATIONS

The objective of this research is to examine the effect of message’s regulatory focus (promotion versus prevention) and product types (hedonic versus utilitarian) on advertising effectiveness, as well as how direct product experience alters these effects. The findings show that, for hedonic products, promotion messages are more persuasive, generate more positive product attitudes, and willingness to pay a higher price than prevention messages. For utilitarian products, prevention messages are more persuasive and generate more positive product attitudes than promotion messages. However, product trial moderates most of these effects. Managerial implications of these results are discussed.Hedonic and utilitarian products, Product Trial, Regulatory focus.

On the IR/UV mixing and experimental limits on the parameters of canonical noncommutative spacetimes

We investigate some issues that are relevant for the derivation of experimental limits on the parameters of canonical noncommutative spacetimes. By analyzing a simple Wess-Zumino-type model in canonical noncommutative spacetime with soft supersymmetry breaking we explore the implications of ultraviolet supersymmetry on low-energy phenomenology. The fact that new physics in the ultraviolet can modify low-energy predictions affects significantly the derivation of limits on the noncommutativity parameters based on low-energy data. These are, in an appropriate sense here discussed, ``conditional limits''. We also find that some standard techniques for an effective low-energy description of theories with non-locality at short distance scales are only applicable in a regime where theories in canonical noncommutative spacetime lack any predictivity, because of the strong sensitivity to unknown UV physics. It appears useful to combine high-energy data, from astrophysics, with the more readily available low-energy data.Comment: 14 page

Cornwall-Jackiw-Tomboulis effective potential for canonical noncommutative field theories

We apply the Cornwall-Jackiw-Tomboulis (CJT) formalism to the scalar $\lambda \phi^{4}$ theory in canonical-noncommutative spacetime. We construct the CJT effective potential and the gap equation for general values of the noncommutative parameter $\theta_{\mu\nu}$. We observe that under the hypothesis of translational invariance, which is assumed in the effective potential construction, differently from the commutative case ($\theta_{\mu\nu}= 0$), the renormalizability of the gap equation is incompatible with the renormalizability of the effective potential. We argue that our result, is consistent with previous studies suggesting that a uniform ordered phase would be inconsistent with the infrared structure of canonical noncommutative theories.Comment: 15 pages, LaTe

Study of germination indicatives of Calendula officinalis L. seeds

To identify MMB and germinal capacity, were study 15 local populations of Calendula from different localities of Caras- Severin district. Results obtained through viability testing and monitoring seeds to Calendula species allowed to identify some germination indicatives of biologic material. Taking in view the fact that germination tests of spontaneous flora were very complexe, it was considered that a part of seeds couldn’t be, however, taken from germinal break. From the investigations made in Sacu, Tincova, Prisaca, Jupa, Caransebes, Iaz, Obreja, Glimboca, Otelu Rosu, Zavoi, Valea Bistrei, Voislova, Vama Marga, Bautar, Bucova localities on Calendula seeds it was determined MMB and bordered in limits admitted by specialists. Laboratory germination, reported to germinal seeds number, had significantly varied among localities and had the limits between 3.3- 90.0%. In case of germinal energy value the collected samples from Caras-Severin district reported to seed category varied between 3.3- 86.6% for small and medium seeds, respectively 6.6-90.0% for seeds of big category

On the Meaning of the String-Inspired Noncommutativity and its Implications

We propose an alternative interpretation for the meaning of noncommutativity of the string-inspired field theories and quantum mechanics. Arguments are presented to show that the noncommutativity generated in the stringy context should be assumed to be only between the particle coordinate observables, and not of the spacetime coordinates. Some implications of this fact for noncomutative field theories and quantum mechanics are discussed. In particular, a consistent interpretation is given for the wavefunction in quantum mechanics. An analysis of the noncommutative theories in the Schr\"odinger formulation is performed employing a generalized quantum Hamilton-Jacobi formalism. A formal structure for noncommutative quantum mechanics, richer than the one of noncommutative quantum field theory, comes out. Conditions for the classical and commutative limits of these theories have also been determined and applied in some examples.Comment: References, comments, and footnotes are included; some changes in section

Perturbed nonlinear models from Noncommutativity

By means of the Ehrenfest's Theorem inside the context of a noncommutative Quantum Mechanics it is obtained the Newton's Second Law in noncommutative space. Considering discrete systems with infinite degrees of freedom whose dynamical evolutions are governed by the noncommutative Newton's Second Law we have constructed some alternative noncommutative generalizations of two-dimensional field theories.Comment: 6 pages. v2 minor changes added and references adde

Noncommutative quantum mechanics and Bohm's ontological interpretation

We carry out an investigation into the possibility of developing a Bohmian interpretation based on the continuous motion of point particles for noncommutative quantum mechanics. The conditions for such an interpretation to be consistent are determined, and the implications of its adoption for noncommutativity are discussed. A Bohmian analysis of the noncommutative harmonic oscillator is carried out in detail. By studying the particle motion in the oscillator orbits, we show that small-scale physics can have influence at large scales, something similar to the IR-UV mixing

Parikh-Wilczek Tunneling from Noncommutative Higher Dimensional Black Holes

We study tunneling of massless and massive particles through the smeared quantum horizon of the extra-dimensional Schwarzschild black holes. The emission rate of the particles' tunneling is modified by noncommutativity effects in a bulk spacetime of dimension $d$. The issues of information loss and possible correlations between emitted particles are discussed. We show that even by considering both noncommutativity and braneworld effects, there is no correlation between different modes of evaporation at least at late-time and within approximations used in the calculations. However, incorporation of quantum gravity effects such as modification of the standard dispersion relation or generalization of the Heisenberg uncertainty principle, leads to the correlation between emitted particles. Although time-evolution of these correlations is not trivial, a part of information coming out of the black hole can be preserved in these correlations. On the other hand, as a well-known result of spacetime noncommutativity, a part of information may be preserved in a stable black hole remnant.Comment: 23 pages, 1 figure, Accepted for publication in JHE

Advertising and product trial: The impact of product type and attribute information on consumer evaluations

Two popular promotional methods, advertising and product sampling, are used by companies to encourage consumers to buy their products. An important body of research has shown that advertising can influence consumers\u27 subsequent trial experience, especially for low diagnostic products for which consumers lack the ability or motivation to confirm (or disconfirm) the ad claims. In this dissertation study, the author investigates the effect of attribute type (search versus experiential), claim objectivity (objective versus subjective) and product type (hedonic versus functional) on consumers\u27 post-trial evaluations (i.e., expectancy values, product attitude, purchase intention, and product choice) of highly diagnostic products. The results indicate that consumers attach greater importance to the experience of a hedonic than a functional product, resulting in more positive post-trial evaluations of the hedonic product. Experiential attribute advertisements also generate more positive post-trial evaluations of a hedonic than a functional product. Further, for functional products, search attribute claims conveyed in a pre-trial ad result in more positive post-trial evaluations than experiential attribute claims or than trial alone. For hedonic products, advertising does not seem to be helpful in guiding product experience; for these products, trial is most important. In the context of these findings, I discuss the contributions to the advertising-trial literature, as well as the managerial implications. I conclude with several limitations of the study and with suggestions for future research.
