Abstract: This paper presents an experimental study of a mechanism that is commonly used to sell multiple heterogeneous goods. The novel feature of this procedure is that instead of selling each good in a separate auction, the seller executes a single auction in which buyers, who may be interested in completely different goods, compete for the right to choose a good. We provide experimental evidence that a Right-to-Choose (RTC) auction can generate more revenue than the theoretically optimal auction. Moreover, in contrast to the “optimal” auction, the RTC auction is approximately efficient in the sense that the surplus it generates is close to the maximal one. Furthermore, a seller who would like to retain some of his goods can generate more revenue with a restricted RTC auction in which not all rights-to-choose are sold, than with the theoretically optimal auction.

PAPER , *SENSORY perception , *ARCHITECTURE , *CONSTRUCTION , *EVIDENCE - Abstract
Smell is often regarded as an ancillary perception in primates, who seem so dominated by their sense of vision. In this paper, we will portray some aspects of the significance of olfaction to human life and speculate on what evolutionary factors contribute to keeping it alive. We then outline the functional architecture of olfactory sensory neurons and their signal transduction pathways, which are the primary detectors that render olfactory perception possible. Throughout the phylogenetic tree, olfactory neurons, at their apical tip, are either decorated with cilia or with microvilli. The significance of this dichotomy is unknown. It is generally assumed that mammalian olfactory neurons are of the ciliary type only. The existance of so-called olfactory microvillar cells in mammals, however, is well documented, but their nature remains unclear and their function orphaned. This paper discusses the possibility, that in the main olfactory epithelium of mammals ciliated and microvillar sensory cells exist concurrently. We review evidence related to this hypothesis and ask, what function olfactory microvillar cells might have and what signalling mechanisms they use. [ABSTRACT FROM AUTHOR]

The article offers information on the additional evidence about the books of Baldassarre Castiglione, a Renaissance author in Italy. The author states that there are three more documents that appeared concerning Castiglione's acquisitions of books. These papers are to be found in Cassetta 6 of the Archivio Castiglioni, in the Archivio di Stato at Mantua. He adds that the documents consist of two letters together with a list of payments and expenditures, which a Mantuan merchant Benedetto Adelardo Da Porto addressed to Castiglione in 1523. Furthermore, the author says that the first of these papers is drafted on September 12, 1523 and the others are written around two months later.

MATHEMATICAL models ,EVIDENCE ,QUANTITATIVE research ,PAPER ,COLLEGE teachers - Abstract
On the basis of a variety of evidence, including the paper with Professor Harold Watts and a paper by the author, the case for seeking and frequently using disaggregated data seemed strong, but one nagging concern remained. Suppose, as seems likely, the microcomponents exhibit different behaviors. In this case it might not be sensible to pool the data and treat it as a single sample from a single universe. This paper copes directly with this issue, and demonstrates the importance of using disaggregated data even when microcomponents. Instead of using a simulation to study aggregation across components with different behaviors, one could have attempted a mathematical deduction of the effects. In order to do this certain simplifying assumptions would need to be introduced in order to make the problem tractable. Another approach to the problem of aggregation is to use data from the real world to fit models at different levels of aggregation, and then to evaluate the relative worth of these models by means of some quantitative measure.

Ninhidrin Uygulanabilen Kağıt Yüzeylerde Parmak İzi Bekleme Sürelerinin İz Üzerindeki Etkilerinin Morfolojik Yönden İncelenmesiBu çalışmada, 20x10 cm. ebatlarındaki A4 kağıdı, gazete kağıdı, karton yüzeylere 4 kişi tarafından , her bir yüzey üzerinde ayrı ayrı olacak şekilde parmak izleri bırakılmış olup parmak izleri oda ortamında 1, 3, 10, 30, 60, 90, 120, 150 ve 180 gün bekletilmiştir. Bekleme süreleri neticesinde elde edilen parmak izlerinin karakteristik özellikleri sayılarak referans parmak izlerinin karakteristik sayıları ile karşılaştırılıp, mukayeseye elverişli olup-olmadığı kayıt edilmiştir.Çalışma sonrasında elde edilen sonuçlar ile kağıt yüzeylere temas zamanının ortaya çıkarılması amacı ile çek, senet, kitap, intihar mektubu, terör dokümanları, narkotik ve psikotrop maddelerin ambalajları ve benzeri kağıt yüzeylerdeki asıl temas zamanı, ıslak imza ve benzeri notların oluşturulma zamanı ya da belgelerdeki tarih ile parmak izi temas zamanı uyumunun ortaya konulması hedeflenmiştir.Çalışma tamamlanması ile elde edilen sonuçlara göre,- A4 kağıt yüzeylerden elde edilen parmak izlerinin 150 güne kadar elverişli olduğu,- Gazete kağıdı yüzeylerden elde edilen parmak izlerinin 60 güne kadar elverişli olduğu,- Karton yüzeylerden elde edilen parmak izlerinin ise 30 günden sonra elverişsiz olduğu tespit dilmiştir. 180 gün bekleyen parmak izlerinin tamamında birtakım karakteristik özellikler olduğu gözlenmiş olsa da tamamının mukayeseye elverişsiz olduğu tespit edilmiştir.Çalışma ile elde edilen sonuçlara bakıldığında, karton yüzeylerde bekleme sürelerine bağlı olarak gün geçtikçe elde edilen izlere ait karakteristik sayılarının gazete kağıdı ve A4 yüzeylere ait elde edilen karakteristik özelliklere nazaran azaldığı ve izlerin morfolojik bakımdan zayıfladığı görülmüştür. Gazete kağıdı yüzeylerde yer alan izlere ait karakteristik özellik sayısının da A4 yüzeylerde yer alan izlere ait karakteristik özelliklere göre daha az olduğu ve izlerin gün geçtikçe zayıfladığı gözlemlenmiştir.Elde edilen sonuçlar değerlendirildiğinde; kağıt yüzeylerde temas zamanının ortaya konmasında, A4, gazete kağıdı ve karton yüzeylerin, sahip olduğu yoğunluk, yüzey özelliği, gözenekli yüzey yapısı, sahip olduğu lif oranı, dolgu maddeleri, yapıştırma maddeleri, boyar maddeler ile nem, sıcaklığın etkisi ile parmak izinde herhangi bir kalıntı kalıp kalmadığı(yağ, kan vb.) gibi yapısal özelliklere bağlı olarak zamanla fiziksel ve kimyasal değişikliklere uğrayarak morfolojik olarak elverişli olma niteliğini kaybettiği anlaşılmıştır. Investigation of the Effects of Fingerprint Waiting Times on Traces of Ninhydrin-Applicable Paper Surfaces MorphologicallyIn this study, fingerprints were left on each surface of A4 paper, newspaper paper, cardboard surfaces(surfaces dimension 20x10 cm.) by 4 people and fingerprints were kept in room environment for 1, 3, 10, 30, 60, 90, 120, 150 and 180 days. The characteristics of the fingerprints obtained at the end of the waiting periods are counted and compared with the characteristic numbers of the reference fingerprints, and it is recorded that they are suitable for comparison.With the results obtained after the study; it is aimed to establish the time of creation of the time of contact with the paper surfaces and the actual contact time on paper surfaces such as checks, bills, books, suicide letters, terrorist documents, packagings of narcotics and psychotropic substances and the wet signature and similar notes or the time of the fingerprint contact with the date of the documents.According to the results obtained by the completion of the study, it has been found that;-finger prints from A4 paper surfaces are available for up to 150 days,-finger prints obtained from newsprint surfaces are suitable for up to 60 days,-fingerprints obtained from cardboard surfaces are unfavorable after 30 days. It has been observed that all of the fingerprints that were waiting for 180 days had some characteristic properties, but all were found to be inferior to each other.When the results obtained from the study are considered; it was observed that the characteristic numbers of the traces obtained day by day due to the waiting times on the cardboard surfaces decreased as compared with the characteristics obtained from newspaper and A4 surfaces and the traces were morphologically weakened. It has been observed that the number of characteristic features of the traces on newspaper surfaces is less than that of the traces on the A4 surfaces and that the traces are getting weaker day by day.When the results obtained are evaluated; to be revealed contact time on paper surfaces, it has been understood that A4, newspaper and cardboard surfaces have lost its morphological suitability due to physical and chemical changes over time due to structural features such as no residue on the fingerprint (fat, blood, etc.), density, surface properties, porous surface structure, fiber ratio, filler materials, bonding materials, humidity and temperature effects. 96

The author reacts to comments made to his article. Perhaps Professor C. Roseman has overstated his case a bit when he asserts that three aspects of the author's paper may have been "quite misleading." Perhaps Roseman's concern about the theory of stepwise regression may be valid, but the author is happy to be able to set his mind at ease about the real world evidence with which he dealt. Perhaps Roseman has fallen into the beguiling trap of confusing statistical association with cause-and-effect explanation. Certainly population continued to increase in many resort areas during the 1970s, but one must entertain serious doubts about anyone who tries to ex- plain population increase by counting the number of empty houses.
