Construction of facilities under asymmetric information: do constitutional constraints matter?

This paper studies construction of facilities in a federal state under asymmetric information. A country consists of two regions, each ruled by a local authority. The federal government plans to construct a facility in one of the regions. The facility generates a local value in the host region and has spillover effects in the other region. The federal government does not observe the local value because it is the local authority's private information. 80 the federal governrnent designs an incentive-compatible mechanism, specifying if the facility should be constructed and a balanced scheme of interregional transfers to finance its cost. The federal governrnent is constitutionally constrained to respect a given leveI of each region's welfare. We show that depending upon the facility's local value and the spillover effect, the governrnent faces different incentive problems. Moreover, their existence depends crucially on how stringent constitutional constraints are. Therefore, the optimal mechanism will also depend upon these three features of the model.

Dos atos confessos aos afetos não-ditos: Um olhar sob as múltiplas experiências femininas a partir da análise dos discursos jurídicos, jornalísticos e orais

Women, subjectiveness, experimentations. This paper walks through gender, sexuality, body and subjectivity, bounding as the focus denaturalize the representations of womanlinessstaff and manliness and the modeled subjectivity by normative discusses that shows the transcendency based on multiplicities of experiences, wishes and life way wattled by men and women from the Caicó City s society in the decades from 1900 to 1945. For this, it was adopted a dialogic methodology inlcluding bibliographic and theorist references as well as sources like articles from Jornal das Moças (Lady s Journal); defloration s crime processes, abortion, infanticide and body lesions; iconographic sources and Caicó citizen memories in the period commented. Based on that sources, this work analyze the discursive construction of feminine through Justice and Jornal das Moças that paved by sanitarian, normalizing and moralizing discourses has spread clichés and stereotypes of womanlinessstaff and manliness, which has resulted by to universalize the experiences feminines in polarities and binary oppositions regarding to manliness, it has delineated them as asexual, irrational, anesthesiaed for pleasure and biologically meant to home activities modeling subjectivities that did not create ways for the singularization processes. This polarities, effects of sexual regulatory practices and gender legitimate the representations of courtship, maternity and honor, that although it has been incorporated not passivant on the building of the poor men and women subjectivity, it did not support itself in view of socio-cultural and economic reality of the poorest society side. Therefore, on this work emerge a plurality of women who has transited past the public sphere, who interlaced amorous informal relationships, who has kept relationships before the marriage, who hás established multiples familiar arrangements and helpful networks, who was single mothers without being considered dishonored women by social groups, who made matrimonial agreements without the rules of a formal civil marriage, who made use of beverageey to provoke the menstruation constituting multiples ways to experiment the life. This subjective feminine experimentations turned it possible to notice that representations concerning about the body, sexuality, date, maternity and honor of this women has constituted itself while molecularies and particulares . It was the affection not commented of the feminine sexuality that turned it possible to analyze the construction of singular subjectivities as a opened process, continuous, active, begetting new lands, life ways and wishes cartographies

Narrativas infantis: o que nos contam as crianças de suas experiências no hospital e na classe hospitalar

This dissertation focuses on the narratives of children hospitalized with chronic diseases. The overall goal is to deduce, from the look of the child health care, hospital class contributions to the process of school inclusion. The research is part of the qualitative ethnographical approach and is based on the principles and research methods (auto)biographical in education and schooling in hospital. Participated in the investigation 05(five) children, aged between 06 (six) and 12 (twelve) years of age, treated at the Center for Children s Onco-Hematology, Varela Santiago Children s Hospital in Natal-RN. The corpus used for the analysis comprises five (05) narrative interviews, 03 (three) drawings made by children as well as records in the researcher s field diary. The sources were collected during the months of August 2010 to February 2011. The analysis revealed that the inclusion of the hospital class, and ensure the right to education, contributes to the construction of strategies for coping with illness and hospitalization, as it promotes autonomy, comfort, playfulness and self-knowledge, the rand the world, easing the stress of hospitalization. The figure of the teacher took the class hospital in the voices of children, a reliever and minimizing the role of double exclusion that cause illness and hospitalization, showing the contributions to (re) construction of identity and subjectivity constitution strengthened. The children interviewed said that the hospital class leave the hospital more cheerful. The playfulness and learning experiences in the hospital are seen by children as actions that go beyond the physical treatment of the disease, since it provides them with acceptance and understanding of hospitalization and illness, to give them affective security and emotional. In conclusion, the narratives of children confirm that the service class hospital ensures continuity of schooling, but they reveal, namely, that this service provides them socialization among peers and with adults, strengthening the emotional, social and cognitive biopsychosocial perspective of attention

Construction of an alkaline phosphatase-liposome system: a tool for biomineralization study

Alkaline phosphatase is required for the mineralization of bone and cartilage. This enzyme is localized in the matrix vesicle, which plays a role key in calcifying cartilage. In this paper. we standardize a method for construction an alkaline phosphatase liposome system to mimic matrix vesicles and examine a some kinetic behavior of the incorporated enzyme. Polidocanol-solubilized alkaline phosphatase, free of detergent, was incorporated into liposomes constituted from dimyristoylphosphatidylcholine (DMPC), dilaurilphosphatidylcholine (DLPC) or dipalmitoylphosphatidylcholine (DPPC). This process was time-dependent and >95% of the enzyme was incorporated into the liposome after 4 h of incubation at 25 degreesC. Although, incorporation was more rapid when vesicles constituted from DPPC were used, the incorporation was more efficient using vesicles constituted from DMPC. The 395 nm diameter of the alkaline phosphatase-liposome system was relatively homogeneous and more stable when stored at 4 degreesC.Alkaline phosphatase was completely released from liposome system only using purified phosphatidylinositol-specific phospholipase C (PIPLC). These experiments confirm that the interaction between alkaline phosphatase and lipid bilayer of liposome is via GPI anchor of the enzyme, alone. An important point shown is that an enzyme bound to liposome does not lose the ability to hydrolyze ATP, pyrophosphate and p-nitrophenyl phosphate (PNPP), but a liposome environment affects its kinetic properties, specifically for pyrophosphate.The standardization of such system allows the study of the effect of phospholipids and the enzyme in in vitro and in vivo mineralization, since it reproduces many essential features of the matrix vesicle.

Patterns of Gene Expression in the Bovine Corpus Luteum Following Repeated Intrauterine Infusions of Low Doses of Prostaglandin F2alpha

Natural luteolysis involves multiple pulses of prostaglandin F2alpha (PGF) released by the nonpregnant uterus. This study investigated expression of 18 genes from five distinct pathways, following multiple low-dose pulses of PGF. Cows on Day 9 of the estrous cycle received four intrauterine infusions of 0.25 ml of phosphate-buffered saline (PBS) or PGF (0.5 mg of PGF in 0.25 ml of PBS) at 6-h intervals. A luteal biopsy sample was collected 30 min after each PBS or PGF infusion. There were four treatment groups: Control (n = 5; 4 PBS infusions), 4XPGF (4 PGF infusions; n = 5), 2XPGF-non-regressed (2 PGF infusions; n = 5; PGF-PBS-PGF-PBS; no regression after treatments), and 2XPGF-regressed (PGF-PBS-PGF-PBS; regression after treatments; n = 5). As expected, the first PGF pulse increased mRNA for the immediate early genes JUN, FOS, NR4A1, and EGR1 but unexpectedly also increased mRNA for steroidogenic (STAR) and angiogenic (VEGFA) pathways. The second PGF pulse induced immediate early genes and genes related to immune system activation (IL1B, FAS, FASLG, IL8). However, mRNA for VEGFA and STAR were decreased by the second PGF infusion. After the third and fourth PGF pulses, a distinctly luteolytic pattern of gene expression was evident, with inhibition of steroidogenic and angiogenic pathways, whereas, there was induction of pathways for immune system activation and production of PGF. The pattern of PGF-induced gene expression was similar in corpus luteum not destined for luteolysis (2X-non-regressed) after the first PGF pulse but was very distinct after the second PGF pulse. Thus, although the initial PGF pulse induced mRNA for many pathways, the second and later pulses of PGF appear to have set the distinct pattern of gene expression that result in luteolysis.

Construction of a river buffalo (Bubalus bubalis) whole-genome radiation hybrid panel and preliminary RH mapping of chromosomes 3 and 10

The buffalo (Bubalus bubalis) not only is a useful source of milk, it also provides meat and works as a natural source of labor and biogas. To establish a project for buffalo genome mapping a 5,000-rad whole genome radiation hybrid panel was constructed for river buffalo and used to build preliminary RH maps from two chromosomes (BBU 3 and BBU10). The preliminary maps contain 66 markers, including coding genes, cattle ESTs and microsatellite loci. The RH maps presented here are the starting point for mapping additional loci, in particular, genes and expressed sequence tags that will allow detailed comparative maps between buffalo, cattle and other species to be constructed. A large quantity of DNA has been prepared from the cell lines forming the RH panel reported here and will be made publicly available to the international community both for the study of chromosome evolution and for the improvement of traits important to the role of buffalo in animal agriculture.
