A technique is proposed for the certification of liquid thermostats, based on the use of reference points reproduced in miniature ampoules. The results of experimental studies are presented on the example of reproducing the reference point of indium and gallium using miniature ampoules.

The mere preannouncement of a new product can affect consumer choice, thus complicating preannouncement strategy. This is because a preannounced product that is unavailable immediately can still be one of the alternatives in a consumer’s mind at the time of choice. Such unavailable products, also known as phantom products, influence the reference point that consumers compare alternatives to when making a choice, as has been widely demonstrated in experimental studies. Thus, in addition to encouraging consumers to postpone purchase in favor of a future product, preannouncement also changes their preference for the currently available products when consumers do not prefer to postpone. In this paper we explore preannouncement strategy by analyzing a model that incorporates the effect of new product preannouncement (NPP) on consumer preferences and compare the results with a benchmark case in which consumer preferences across the existing products are not influenced by preannouncement. We find that when we take into account the effect of NPP on consumer preferences across the existing products, although postponement of purchase by some consumers remains beneficial, the preference for the current product offering with a lower quality can suffer so much that the significant lowering of current profits is not offset by future gains. Thus, preannouncement may no longer be the optimal strategy for the firm with a lower-quality product, which in turn explains the “Osborne effect.” Our results also challenge the conventional wisdom in new product preannouncement literature. This paper was accepted by Juanjuan Zhang, marketing.

Mammalian spindles are generally large and may contain over a thousand microtubules (MTs). For this reason they are difficult to reconstruct in three dimensions and many researchers have chosen to study the smaller and simpler spindles of lower eukaryotes. Nevertheless, the mammalian spindle is used for many experimental studies and it would be useful to know its detailed structure.We have been using serial cross sections and computer reconstruction methods to analyze MT distributions in mitotic spindles of PtK cells, a mammalian tissue culture line. Images from EM negatives are digtized on a light box by a Dage MTI video camera containing a black and white Saticon tube. The signal is digitized by a Parallax 1280 graphics device in a MicroVax III computer. Microtubules are digitized at a magnification such that each is 10-12 pixels in diameter.

Abstract. Employing one correlational and two experimental studies, this paper examines the influence of attachment styles (secure, anxious, avoidant) on a person’s experience of equity in intimate relationships. While one experimental study employed a priming technique to stimulate the different attachment styles, the other involved vignettes describing fictitious characters with typical attachment styles. As the specific hypotheses about the single equity components have been developed on the basis of the attachment theory, the equity ratio itself and the four equity components (own outcome, own input, partner’s outcome, partner’s input) are analyzed as dependent variables. While partners with a secure attachment style tend to describe their relationship as equitable (i.e., they give and take extensively), partners who feel anxious about their relationship generally see themselves as being in an inequitable, disadvantaged position (i.e., they receive little from their partner). The hypothesis that avoidant partners would feel advantaged as they were less committed was only supported by the correlational study. Against expectations, the results of both experiments indicate that avoidant partners generally see themselves (or see avoidant vignettes) as being treated equitably, but that there is less emotional exchange than is the case with secure partners. Avoidant partners give and take less than secure ones.

Abstract. In this work, we investigated individual differences in cognitive reflection effects on delay discounting – a preference for smaller sooner over larger later payoff. People are claimed to prefer more these alternatives they considered first – so-called reference point – over the alternatives they considered later. Cognitive reflection affects the way individuals process information, with less reflective individuals relying predominantly on the first information they consider, thus, being more susceptible to reference points as compared to more reflective individuals. In Experiment 1, we confirmed that individuals who scored high on the Cognitive Reflection Test discount less strongly than less reflective individuals, but we also show that such individuals are less susceptible to imposed reference points. Experiment 2 replicated these findings additionally providing evidence that cognitive reflection predicts discounting strength and (in)dependency to reference points over and above individual difference in numeracy.
