Repeated games with asymmetric information and random price fluctuations at finance markets : the case of countable state space
No full textThis paper is concerned with multistage bidding models introduced by De Meyer and Moussa Saley (2002) to analyze the evolution of the price system at finance markets with asymmetric information. The zero-sum repeated games with incomplete information are considered modeling the bidding with countable sets of possible prices and admissible bids. It is shown that, if the liquidation price of a share has a finite variance, then the sequence of values of n-step games is bounded and converges to the value of the game with infinite number of steps. We construct explicitly the optimal strategies for this game. The optimal strategy of Player 1 (the insider) generates a symmetric random walk of posterior mathematical expectations of liquidation price with absorption. The expected duration of this random walk is equal to the initial variance of liquidation price. The guaranteed total gain of Player 1 (the value of the game) is equal to this expected duration multiplied with the fixed gain per step.Multistage bidding, asymmetric information, repeated games, optimal strategy.
Collaboration for Community Development in the Cedar-Riverside Neighborhood
No full textprofessional paper in partial fulfillment of the Master of Public Policy degree requirementThis report was the result of a research partnership between the Cedar-Humphrey Action for Neighborhood and Community Engagement (CHANCE) and the West Bank Community Coalition (WBCC). The purpose of this report is to determine ways in which neighborhood organizations, and specifically the WBCC, can be an effective collaborator within the Cedar-Riverside Partnership, Dania Partners, the University District Partnership Alliance, and any future collaboration that may develop. This report was based on a literature review of twenty articles, twenty interviews with members of collaborations within and outside of Cedar-Riverside, and five case studies of local and national collaborations for community development.
The WBCC is currently the only organization within Cedar-Riverside that is a member of the Cedar-Riverside Partnership, Dania Partners, and the University District Partnership Alliance. While this presents an opportunity to promote community engagement, several barriers have been identified to collaboration including a need for a unifying mission, a lack of collaborative capacity, and barriers to communication. However, collaboration is seen as an asset, and there is hope within Cedar-Riverside for new leadership.
The theories to collaboration presented in this report are based upon the idea of asset-based community development, which advocates identifying resources within the community that can be mobilized for community development. Additionally, several factors were identified as being present within both effective neighborhood organizations, and collaborations for community development.
The five case studies revealed several overarching lessons for effective collaboration, including the need for a strong vision for collaboration, the importance of the structure of the partnership, and the need for an effective use of available resources. Additionally, the case studies showed the importance of staff, and displayed how effective collaboration can increase the prominence of an organization within a community.Corn, Jeff; Domansky, Scott.

Estudo epidemiológico de base populacional, de corte transversal, realizado após a aprovação do Comitê de Ética da Escola de Enfermagem da Universidade de São Paulo. Dois mil cento e sessenta e dois indivíduos, com idade igual ou superior a 18 anos, condições físicas e mentais adequadas e que aceitaram a participar do estudo, compuseram a amostra, estabelecida a partir de amostragem estratificada por conglomerado, constituídos pelas ruas sorteadas aleatoriamente dentro dos 390 setores censitários do município. Todos os residentes nos domicílios das ruas sorteadas, que atenderam aos critérios de inclusão foram entrevistados utilizando-se dois instrumentos: Dados demográficos e o Hábito intestinal na comunidade (adaptado e validado para a língua portuguesa por Domansky e Santos, 2007). Os dados foram submetidos aos testes de Qui-Quadrado e Exato de Fischer. O predomínio foi do sexo feminino (1203 / 56%); média etária de 40,6±16,4; brancos (1591/74%); união estável (1290 / 60%); 9 a 12 anos de estudo (784/ 36%); 37% pessoas sem ocupação definida; 44% tinham remuneração entre 2 e 3,9 SM; 38% com renda per capita entre 0,6 a 1 salário mínimo.

O histórico de parto e ginecológico: 886 (74%) tiveram partos, 709 (73%) com padrão intestinal normal; 432 (49%) entre 31 e 50 anos; 168 (14%) tiveram um parto normal; destas 33 (3%) tiveram laceração anal pós-parto que necessitou de intervenção cirúrgica; porém mantiveram o padrão intestinal normal (25/75%); 109 (9%) fizeram histerectomia (109 /9%), 90 (90%) padrão intestinal normal e menos de um por cento tiveram retocele e quatro (50%) eram constipadas. Os fatores de risco para incontinência anal: 35 (2%) radioterapia pélvica, 133 (6%) diabetes mellitus, 330 (15%) doenças ou distúrbios do sistema nervoso, 291 (13%) lesão na coluna espinhal e 29 (1%) relataram o acidente vascular encefálico (AVE), para todos os fatores houve predomínio do padrão intestinal normal, predomínio feminino para distúrbios do sistema nervoso e AVE. Este estudo permitiu conhecer o hábito intestinal da população geral de uma cidade no norte do Paraná, os fatores de risco para IA que estão expostos, cooperando para a elucidação do tema entre a população, ampliando os conhecimentos daqueles que atuam na área, e colaborando para o desenvolvimento de programas de prevenção ou diagnóstico precoce das doenças intestinaisThe objective of this study was to evaluate the bowel habits and anal incontinence (AI) risk factors in adults living in the urban area of Londrina, PR, Brazil. This population-based, transversal epidemiological study was carried out after being approved by the University of São Paulo Nursing School Ethics Committee. Population sample established from a stratified sampling procedure by a conglomerate constituted of streets taken randomly from 390 county census sectors, included 2162 individuals , 18 years old and over, in adequate physical and mental conditions, who accepted to participate in the study. All residents in the selected streets who met the inclusion criteria established by the study were interviewed, using two instruments: Demographic data and the Bowel function in the community (adapted and validated for the Portuguese language by Domansky and Santos, 2007). Data were submitted to Chi-square and Fischer exact tests. There was a predominance of female subjects (1203/56%); ages 40,6 ± 16,4; white (1591/74%); with a stable relationship (1290/60%), with 9 to 12 years of formal education ( 784/36%), subjects without a defined job (37%) with salaries around 2 to 3,9 / minimum wage (44%) and per capita income between 0,6 to one/minimum wage (38%). As for normal intestinal pattern (1.875/87%; p<0,0001), there was the predominance of one bowel movement per day (1.133/52%; p<0,0001), among women (968/52%; p<0,0001); whites (1591/85%; p<0,0001), absence of defecation strain (1956/90%), soft feces (1379/64%), total rectal emptying (1938/90%). Constipated intestinal pattern (261/12,1%), among women (219/84%), defecation strain (99/41,8%), hard feces (176/67%); incomplete rectal emptying (99/38%). Diarrheic intestinal pattern (26/1,2%), no defecation strain (26/100%) liquid and soft feces (5/19%), total rectal emptying (16/61%). Prevalence of anorectal diseases was 53 (2%) abscesses, 22 (1%) fistules, 81 (3%) fissures, 20(1%) rectal prolapse, 30 (1%) anal traumas; 229 (11%) hemorrhoidal disease 58 (3%) ; anorectal surgeries, mainly among females. Gynecological and delivery history, 886 (74%) had deliveries, 709 (73%) with normal intestinal pattern; 432 (49%) between 31 and 50 years old; 168 (14%) had normal deliveries; 33 (3%) with postpartum laceration that needed surgical intervention; however, they maintained a normal intestinal pattern (25/75%); 109 (9%) had hysterectomy (109 /9%), 90 (90%) normal intestinal pattern and less than one percent had rectocele and four (50%) were constipated. Anal incontinence risk factors, 35 (2%) pelvic radiotherapy, 133 (6%) diabetes mellitus, 330 (15%) nervous systems diseases and dysfunctions, 291 (13%) spinal cord lesion and 29 (1%) reported having had an encephalic vascular stroke. In all factors there was the predominance of the normal intestinal pattern; however, females presented more nervous system dysfunctions and encephalic vascular strokes.

Perfused multiwell plate for 3D liver tissue engineering
No full textIn vitro models that capture the complexity of in vivo tissue and organ behaviors in a scalable and easy-to-use format are desirable for drug discovery. To address this, we have developed a bioreactor that fosters maintenance of 3D tissue cultures under constant perfusion and we have integrated multiple bioreactors into an array in a multiwell plate format. All bioreactors are fluidically isolated from each other. Each bioreactor in the array contains a scaffold that supports formation of hundreds of 3D microscale tissue units. The tissue units are perfused with cell culture medium circulated within the bioreactor by integrated pneumatic diaphragm micropumps. Electronic controls for the pumps are kept outside the incubator and connected to the perfused multiwell by pneumatic lines. The docking design and open-well bioreactor layout make handling perfused multiwell plates similar to using standard multiwell tissue culture plates. A model of oxygen consumption and transport in the circulating culture medium was used to predict appropriate operating parameters for primary liver cultures. Oxygen concentrations at key locations in the system were then measured as a function of flow rate and time after initiation of culture to determine oxygen consumption rates. After seven days of culture, tissue formed from cells seeded in the perfused multiwell reactor remained functionally viable as assessed by immunostaining for hepatocyte and liver sinusoidal endothelial cell (LSEC) phenotypic markers.National Institute of Environmental Health Sciences (grant number 5P30ES002109-30)National Institutes of Health (U.S.) (NIH grant number 5R01ES015241)DuPont MIT AlliancePfizer Inc.National Science Foundation (U.S.) (NSF grant number EEC-9843342

Post-Somalia Reform in the Canadian Armed Forces: Leadership, Education, and Professional Development
No full textAfter the “Somalia Affair” of the early 1990s, a government investigation concluded that the Canadian Armed Forces (CAF) had become dysfunctional as a professional military force and needed to be comprehensively reformed. It was perceived to be a deeply-flawed institution whose soldiers were ill-prepared, without discipline, and lacking leadership, leading to systemic breakdown and pointing clearly to an inappropriate organizational culture. The subsequent reform movement initiated by the government in 1997 to address these perceived problems covered a range of issues, but a critical focus was the need to redress the failure of military leadership, alter the way in which the Canadian military perceives of itself as a professional organization, and to inculcate an ethos appropriate to the CAF. This dissertation analyzes that reform process, applying concepts of military innovation and change, organizational culture, and organizational learning to determine which factors had the greatest influence on the introduction and process of change in the post-Somalia context. It assesses the degree to which the reforms specifically dedicated to officer training, education, and professional development have been implemented and the impact they have had on the CAF as an institution. Ultimately, it concludes that the CAF is a fundamentally different institution today than it was when the post-Somalia reform program was first launched. This is undoubtedly a result of its engagement with the reforms and efforts made to introduce new concepts, values, narratives, and behaviours into CAF practices, procedures, and expectations. While it is still not clear that the CAF has completely institutionalized all of the intended changes, a shift in culture has occurred, improvements can be identified, and the process of change and introspection remains ongoing
