Axisymmetric polydimethysiloxane microchannels for in vitro hemodynamic studies
The current microdevices used for biomedical research are often manufactured using microelectromechanical systems (MEMS) technology. Although it is possible to fabricate precise and reproducible rectangular microchannels using soft lithography techniques, this kind of geometry may not reflect the actual physiology of the microcirculation. Here, we present a simple method to fabricate circular polydimethysiloxane (PDMS) microchannels aiming to mimic an in vivo microvascular environment and suitable for state-of-the-art microscale flow visualization techniques, such as confocal µPIV/PTV. By using a confocal µPTV system individual red blood cells (RBCs) were successfully tracked trough a 75 µm circular PDMS microchannel. The results show that RBC lateral dispersion increases with the volume fraction of RBCs in the solution, i.e. with the hematocrit
A Study of Yu-chien Jo-fen
Yü-chien 玉澗, who is as famous as Mu-chi has always been praised till our time as a painter of the “transcendental mode” of the end of the Sung Period and there are fine examples of his works, such as the fragments of the “Scroll of the Eight Views of Hsiao-hsiang” and the fragments of the “View of Lu-shan.” But we have four painters crowned with the name of Yü-chien through the Sung and Yüan Periods, and it is problematical which is the artist of the works we have. Among these four, Mêng Yü-chien i 孟玉澗, who was not a monk and who lived in the latter half of the Yüan Period, can not be and naturally has not been regarded as the artist of these works. As for Pin Yü-chien 彬玉澗, another of the four, we find a poem for his painting in an anthology of a Ch'an monk. But we have not enough material to connect this with the existing “ Yü-chien” works.
The other two are Ying Yü-chien 瑩玉澗 and Yü-chien Jo-fên 玉澗若芬. The author earlier presented a hypothetical idea that the “ Yü-chien” we have is Ying Yü-chien, a poet priest in the circle of the famous Ch'an priest Ch'ih-chüeh Tao-ch'ung 癡絶道冲. The reasons were that he was considered to have been one of the pastime painters of the Ch'an Sect, who have been thought to have encouraged ink painting at the end of the Sung Period and that all of the existing works haye Yü-chien's own poems.
However, after that, the author found several materials which convinced him that the Yü-chien we have is not Ying Yü-chien but chien Jo-fên, and here presents his new theory. It is as follows. In the anthologies of such literati as Wu Shih-tao 呉師道, Chin Lũ-hsiang 金履祥 and Wang Po 王柏, who are from Chin-hua 金華 as well as Yü-chien Jo-fên, and who were active at the end of Sung and the beginning of Yüan, he found the name of Fên Yü-chien; and there he also found the facts that he was good at simple transcendental ink painting and that he always wrote his own poem on his painting. Not only that, he made it clear that the biography of Yü-chien Jo-fên in Sung-chai-mén-pú 松斎梅譜, written by Wu Tai-su 呉太素, is a rather precise record of Jo-fên and Jo-fên's paintings as he saw and heard of them. From these facts, WEM, the author judges it more reasonable to consider this priest of the Tien-t'ai Sect from Chin-hua of Chê-ching Province as the artist of the extant works than to connect Ying Yü-chien, the poet priest, and these works. This new idea rises a new question for the student of Sung and Yüan ink painting, who generally have tended to em phasize the relationship between the Sung and Yüan ink paintings and the church of the Ch'an sect : on the one hand, it proposes a question about artists' personal taste which may, more than the religious attitude of the Chan sect, have promoted this artistic trend, and also a question about the possible relationship of this trend to the tradition of ink painting in Chê-chiang Pro vince and to the prevalance of the transcendental style in the Sung Period.journal articl
Just Get Me to the Church: Assessing Policies to Promote Marriage among Fragile Families
This article examines alternative approaches to encourage family formation among fragile families, including higher cash benefits, more liberal acceptance of welfare applications, more effective child support enforcement, and efforts to increase education and employment of low-income parents. We examine these approaches by refining and expanding previous work on a generalized logit model of the mothers’ actual family formation outcomes, in a hierarchy that includes father absence, father involvement, cohabitation, and marriage. Refinements involve measurements of family formation that make our results more comparable to other studies and new controls for previous fertility with the father of the focal child and with another partner (multiple partner fertility). We estimate these models using interim data from the Fragile Families and Child Well-Being 12 month follow-up Survey. The results indicate that, unlike their effects on mature families, cash benefits increase the odds of family formation (short of marriage) among fragile families and effective child support enforcement increases the odds of marriage. However, the father’s employment status outweighs the effects of these traditional income security policies on family formation, because it affects outcomes all along the hierarchy, including marriage, and its effects are larger. Unlike previous research, our data on previous fertility enables us to separate the effects of previous children in common from multiple partner fertility on family formation. Both significantly affect family formation (though in opposite directions), but even after including these variables, blacks, who are more likely to bring children from previous unions into a new union, have substantially lower odds of cohabitation and marriage than non-Hispanic whites.

Le chien de berger ; développement et signification géographique d'une technique pastorale
Summary.
The author studies the geographical distribution of the « driving dog », able to round and gather the herds, by opposition to the « defending dog », whose sole function is to guard the flocks. The driving dog is a recent technique, typical of Western and Central Europe. It expanded from Iceland where it appeared before the thirteenth century. The author examines the geographical factors of the invention and the expansion of this technique : a) the extinction of the wolves, which allows the canine species to evaluate towards nimble and small forms, succeeding to the ancient motossus ; b) an agrarian landscape of open fields with a complicated pattern of narrow strips, claiming precise movements of the flocks.Résumé.
Etude de la répartition géographique du « chien de conduite », apte à rassembler et diriger les troupeaux, par opposition au « chien de défense », dont la seule fonction est de les garder. Le chien de conduite est une technique récente, caractéristique de l'Europe occidentale et centrale, diffusée à partir de l'Islande où elle est apparue avant le treizième siècle. On examine les facteurs géographiques de l'invention et de l'expansion de cette technique : a) disparition des loups et autres bêtes fauves, permettant l'évolution du chien vers des races de petite taille et agiles qui remplacent les molosses antiques ; b) paysage agraire de champs ouverts à parcellaire lanière complexe, exigeant un parcours précis des animaux.de Planhol Xavier.

The M Word: The Rise and Fall of Interracial Coalitions On Fathers And Welfare Reform
Buoyed by the success of the 1996 Personal Responsibility and Work Opportunities Reconciliation Act (PRWORA), whose time limits and work requirements played a large role in the reduction of the welfare rolls, conservative advocates of welfare reform are now moving to ensure that our welfare system reflects traditional family values as well. Responding to this sentiment, the Bush Administration is encouraging states to use TANF to support marriage promotion efforts and the Administration's 2002 budget includes 60 million President Bush had committed to support efforts to promote responsible fatherhood, not restricted to marriage, has been pared back to $20 million, along with cutbacks in other domestic initiatives that are needed to pay for the "war against terrorism."

Two theories on information asymmetry in finance
This dissertation includes two essays which investigate the effects of information asymmetry in liquidity risk pricing and in agency problems. The brief abstracts of these two essays are presented as follows. The first essay investigates how a risk averse liquidity provider sets optimal limit order book under information asymmetry. I extend the model proposed by Copeland and Galai (1983). First, in response to increasing trade size, a severe risk averse liquidity provider offers convex negatively-sloped bid curves and concave positively-sloped ask curves under information asymmetry. In addition, the simultaneous existence of the risk averse liquidity provider and market information asymmetry is the necessary condition that the liquidity provider offers negatively-sloped bid curves and positively-sloped ask curves. Both numerical analysis and empirical evidence on the limit order book of Taiwan Index Futures support the findings in this essay. In the second essay, I investigate the effects of information asymmetry under the two-tiered agency problem which is commonly observed in a typical organizational structure. I propose the two-tiered agency model and shows that imposing Joint Responsibility policy between Agent_1 (Chief Executive Officer) and Agent_2 (Chief Financial Officer) is NOT a good policy for Principal (Shareholders). Joint Responsibility is that Agent_1 is accused of not identifying in advance Agent_2 who takes on destructive risky projects. I design two cases (Case_1 excludes Joint Responsibility and Case_2 includes it) and prove that Principal’s payoffs in Case_1 weakly dominate that in Case_2. In addition, static comparative analysis shows that how the change of the losses from the bad state of the high risky project, or the parameter of Agent_1’s monitoring costs, alters Agent_1’s monitoring and Principal’s payoffs in equilibrium.Ph.
