Do consumers really know if the price is right ? Direct measures of references price are their implications for retailing
Reference price research suggest that consumers memorize and recall price information when selecting brands for frequently purchased products. In this study, we show that previous price-knowledge surveys provided imperfect estimates of reference price. Further, we propose to use a combination of price recall, price recognition, and deal recognition to measure representations to memorize prices. In addition we identify consumer and product characteristics that explain the variations in price knowledge.price knowledge; reference price; retailing
The construction of meanings for trend in active graphing
The development of increased and accessible computing power has been a major agent in the current emphasis placed upon the presentation of data in graphical form as a means of informing or persuading. However research in Science and Mathematics Education has shown that skills in the interpretation and production of graphs are relatively difficult for Secondary school pupils. Exploratory studies have suggested that the use of spreadsheets might have the potential to change fundamentally how children learn graphing skills. We describe research using a pedagogic strategy developed during this exploratory work, which we call Active Graphing, in which access to spreadsheets allows graphs to be used as analytic tools within practical experiments. Through a study of pairs of 8 and 9 year old pupils working on such tasks, we have been able to identify aspects of their interaction with the experiment itself, the data collected and the graphs, and so trace the emergence of meanings for trend. © 2000 Kluwer Academic Publishers
ENTREPRENEURIAL ALERTNESS THROUGH COGNITIVE SCHEMATA
This article is an investigation into the causes of entrepreneurial alertness, the ability of entrepreneurs to spot new business opportunities in the environment. By drawing from decision theory and schema theory, a model is developed to show how changes in the environment are mediated by entrepreneurial alertness and brought to the situated attention of entrepreneurs for evaluation. Entrepreneurial alertness is seen to be the application of unique schemata that allow the entrepreneur to impute meaning to environmental change that would not be imputed by other managers. It is argued that this arises from differences in schematic richness, schematic association, and schematic priming. These three antecedents may therefore form a basis on which enhanced entrepreneurial alertness can be developedEntrepreneurship; Entrepreneurial alertness, Opportunity spotting; Growth and innovation; SME development
Micro-expression Recognition using Spatiotemporal Texture Map and Motion Magnification
Micro-expressions are short-lived, rapid facial expressions that are exhibited by individuals when they are in high stakes situations. Studying these micro-expressions is important as these cannot be modified by an individual and hence offer us a peek into what the individual is actually feeling and thinking as opposed to what he/she is trying to portray. The spotting and recognition of micro-expressions has applications in the fields of criminal investigation, psychotherapy, education etc. However due to micro-expressionsâ short-lived and rapid nature; spotting, recognizing and classifying them is a major challenge. In this paper, we design a hybrid approach for spotting and recognizing micro-expressions by utilizing motion magnification using Eulerian Video Magnification and Spatiotemporal Texture Map (STTM). The validation of this approach was done on the spontaneous micro-expression dataset, CASMEII in comparison with the baseline. This approach achieved an accuracy of 80% viz. an increase by 5% as compared to the existing baseline by utilizing 10-fold cross validation using Support Vector Machines (SVM) with a linear kernel

Long-term treatment of uterine fibroids with ulipristal acetate
Objective:
To investigate the efficacy and safety of ulipristal acetate (UPA) for long-term treatment of symptomatic uterine fibroids.<p></p>
Design:
Repeated intermittent open-label UPA courses, each followed by randomized double-blind norethisterone acetate (NETA) or placebo.<p></p>
Setting:
European clinical gynecology centers.<p></p>
Patient(s):
Two hundred and nine women with symptomatic fibroids including heavy menstrual bleeding.<p></p>
Intervention(s):
Patients received up to four 3-month courses of UPA 10Â mg daily, immediately followed by 10-day double-blind treatment with NETA (10Â mg daily) or placebo.<p></p>
Main Outcome Measure(s):
Amenorrhea, fibroid volume, endometrial histology.<p></p>
Result(s):
After the first UPA course, amenorrhea occurred in 79% of women, with median onset (from treatment start) of 4Â days (interquartile range, 2â6Â days). Median fibroid volume change was â45% (interquartile range, â66%; â25%). Amenorrhea rates were 89%, 88%, and 90% for the 131, 119, and 107 women who received treatment courses 2, 3, and 4, respectively. Median times to amenorrhea were 2, 3, and 3Â days for treatment courses 2, 3, and 4, respectively. Median fibroid volume changes from baseline were â63%, â67%, and â72% after treatment courses 2, 3, and 4, respectively. All endometrial biopsies showed benign histology without hyperplasia; NETA did not affect fibroid volume or endometrial histology.<p></p>
Conclusion(s):
Repeated 3-month UPA courses effectively control bleeding and shrink fibroids in patients with symptomatic fibroids
Multimedia information technology and the annotation of video
The state of the art in multimedia information technology has not progressed to the point where a single solution is available to meet all reasonable needs of documentalists and users of video archives. In general, we do not have an optimistic view of the usability of new technology in this domain, but digitization and digital power can be expected to cause a small revolution in the area of video archiving. The volume of data leads to two views of the future: on the pessimistic side, overload of data will cause lack of annotation capacity, and on the optimistic side, there will be enough data from which to learn selected concepts that can be deployed to support automatic annotation. At the threshold of this interesting era, we make an attempt to describe the state of the art in technology. We sample the progress in text, sound, and image processing, as well as in machine learning

A randomized clinical trial to compare levonorgestrel-releasing intrauterine system (Mirena) vs trans-cervical endometrial resection for treatment of menorrhagia
Shirin Ghazizadeh1, Fatemeh Bakhtiari1, Haleh Rahmanpour2, Fatemeh Davari-Tanha1, Fatemeh Ramezanzadeh11Valie-Asr Reproductive Health Research Center, Valie-Asr Hospital, Tehran University of Medical Sciences, Tehran, Iran; 2Department of Obstetrics and Gynecology, Ayatollah Mousavi Hospital, Zanjan, IranObjective: To compare the acceptability, efficacy, adverse effects, and user satisfaction of the levonorgestrel intrauterine system (LNG-IUS) and trans-cervical resection of the endometrium (TCRE) for the treatment of menorrhagia.Method: 104 women with menorrhagia were divided into 2 groups: 52 women had the LNG-IUS inserted and 52 underwent TCRE. Menstrual pattern, pictorial blood loss assessment chart score, adverse effects, and rates of acceptability and satisfaction, were recorded at 6 and 12 months after the procedure.Results: After a year there were reductions of 93.9% and 88.4% in menstrual blood loss in the TCRE and LNG-IUS groups, respectively. Amenorrhea was more common in the TCRE group and spotting and systemic effects in the LNG-IUS group. Satisfaction rates of the TCRE group were higher than the LNG-IUS group (80.8% vs 69.2%), but the difference was not statistically significant.Conclusion: Although both treatments were found to be equally effective, LNG-IUS was less invasive and can be advised for younger women with a desire to preserve fertility.Keywords: menorrhagia, trans-cervical endometrial resection, levonorgestrel-releasing intrauterine syste
