Strategic trade policy under uncertainty: Sufficient conditions for the optimality of ad valorem, specific and quadratic trade taxes

In most previous work on strategic trade policy the form of government intervention has been prescribed in advance. In this paper, we apply a solution concept discussed by Klemperer and Meyer for games in which the strategy space consists of the class of all (non state-contingent) price quantity schedules. We examine a series of specific assumptions on demand and supply conditions and derive the associated equilibrium trade policies. We derive welfare implications for all cases examined.

A crise do transporte a??reo no Brasil: 2006-2007

Este estudo de caso aborda a crise vivida pelo setor de transporte a??reo brasileiro nos anos de 2006 e 2007. Deflagrada por um acidente de vulto, a crise teve como protagonistas os controladores de tr??fego a??reo, que, sob suspeita de falha funcional e comunica????o dif??cil com as autoridades do setor, reagiram por meio de uma estrat??gia de opera????o-padr??o (greve branca). Essa situa????o, somada ?? escassez de pessoal, provocou, de novembro de 2006 at?? meados de 2007, o descontrole operacional dos principais aeroportos do pa??s, com grandes preju??zos aos usu??rios. Um novo acidente a??reo, no decorrer da crise, agravou ainda mais a situa????o do setor, expondo defici??ncias estruturais e profissionais ?? opini??o p??blica brasileira, em uma ??rea at?? ent??o considerada segura. O caso relata as tentativas de equacionamento da crise por parte das autoridades respons??veis pela pol??tica de transporte a??reo, frente ao descontentamento e ??s reivindica????es dos controladores de tr??fego a??reo e ?? indigna????o da sociedade. O objetivo do estudo de caso ?? ilustrar uma situa????o de crise e de processo de negocia????o, tendo sido originalmente utilizado em uma oficina sobre negocia????es no setor p??blico. O caso pode ser utilizado como material de apoio em cursos que abordem, entre outros, os seguintes t??picos: negocia????o, gest??o de crises, comunica????o e planejamento estrat??gico

Sample Policy Prohibiting Harassment in the Workplace, 2006

A key component in preventing harassment is having each employer develop and implement a policy which prohibits harassment in the workplace. Having such a policy in place is also an important part of an employer’s defense should a harassment complaint be filed against the employer. This policy should be separate from and in addition to a general anti-discrimination policy. A good policy will set forth procedures that will encourage victims to come forward, that will protect confidentiality of the persons involved, that guards against retaliation, and that brings complaints to a resolution.

Sovereign risk and secondary markets

Conventional wisdom views the problem of sovereign risk as one of insufficient penalties.Foreign creditors can only be repaid if the government enforces foreign debts. And this will onlyhappen if foreign creditors can effectively use the threat of imposing penalties to the country.Guided by this assessment of the problem, policy prescriptions to reduce sovereign risk havefocused on providing incentives for governments to enforce foreign debts. For instance, countriesmight want to favor increased trade ties and other forms of foreign dependence that make themvulnerable to foreign retaliation thereby increasing the costs of default penalties.

Policy Addressing Civil Rights/Discrimination Complaints, January 3, 2011

The Iowa Governor’s Office of Drug Control Policy (ODCP) shall comply with all applicable federal and state laws prohibiting discrimination, as well as the State of Iowa’s Equal Opportunity, Affirmative Action and Anti-Discrimination Policy for Executive Branch Employees (Section 2.40 of Iowa Department of Administrative Services Managers and Supervisors Manual). Federal law prohibits discrimination against individuals or groups, either in employment or in the delivery of services or benefits, on the basis of age, race, color, national origin, religion, sex, or disability. State law prohibits discrimination in the areas of employment, housing, credit, public accommodations and education. Under the Iowa Civil Rights Act of 1965, discrimination, or different treatment, is illegal if based on race, color, creed, national origin, religion, sex, sexual orientation, gender identity, pregnancy, physical disability, mental disability, retaliation (because of filing a previous discrimination complaint, participating in an investigation of a discrimination complaint, or having opposed discriminatory conduct), age (in employment and credit), familial status (in housing and credit) or marital status (in credit). State policy requires all employees and applicants for employment in the executive branch be afforded equal access. The intent of this policy is to ensure that employment opportunities, within the executive branch of state government, are accessible to all persons, and that executive branch agencies do not discriminate against any person because of race, creed, color, religion, sex, national origin, age, or physical or mental disability.

Residents' Rights

Resident rights are guaranteed by the federal Nursing Home Reform Law of 1987, which requires nursing facilities to promote and protect the rights of each resident and places a strong emphasis on individual dignity and self-determination. Residents’ rights include, but are not limited to: • Being treated with respect and dignity • Being free from abuse and chemical and physical restraints • Participating in one’s own care and treatment • Being ensured information is being kept confidential • Managing one’s own finances • Being free to voice grievances, without fear of retaliation • Being able to associate and communicate privately with any person • Being able to send and receive personal mail • Making independent choices • Being able to apply for state and federal assistance without discrimination • Being informed of rights, services available and all charges prior to admission • Being given advance notice of a transfer or discharge

Evolutionary Games in Networked Populations: Models and Experiments

Cooperation and coordination are desirable behaviors that are fundamental for the harmonious development of society. People need to rely on cooperation with other individuals in many aspects of everyday life, such as teamwork and economic exchange in anonymous markets. However, cooperation may easily fall prey to exploitation by selfish individuals who only care about short- term gain. For cooperation to evolve, specific conditions and mechanisms are required, such as kinship, direct and indirect reciprocity through repeated interactions, or external interventions such as punishment. In this dissertation we investigate the effect of the network structure of the population on the evolution of cooperation and coordination. We consider several kinds of static and dynamical network topologies, such as Baraba´si-Albert, social network models and spatial networks. We perform numerical simulations and laboratory experiments using the Prisoner's Dilemma and co- ordination games in order to contrast human behavior with theoretical results. We show by numerical simulations that even a moderate amount of random noise on the Baraba´si-Albert scale-free network links causes a significant loss of cooperation, to the point that cooperation almost vanishes altogether in the Prisoner's Dilemma when the noise rate is high enough. Moreover, when we consider fixed social-like networks we find that current models of social networks may allow cooperation to emerge and to be robust at least as much as in scale-free networks. In the framework of spatial networks, we investigate whether cooperation can evolve and be stable when agents move randomly or performing Le´vy flights in a continuous space. We also consider discrete space adopting purposeful mobility and binary birth-death process to dis- cover emergent cooperative patterns. The fundamental result is that cooperation may be enhanced when this migration is opportunistic or even when agents follow very simple heuristics. In the experimental laboratory, we investigate the issue of social coordination between indi- viduals located on networks of contacts. In contrast to simulations, we find that human players dynamics do not converge to the efficient outcome more often in a social-like network than in a random network. In another experiment, we study the behavior of people who play a pure co- ordination game in a spatial environment in which they can move around and when changing convention is costly. We find that each convention forms homogeneous clusters and is adopted by approximately half of the individuals. When we provide them with global information, i.e., the number of subjects currently adopting one of the conventions, global consensus is reached in most, but not all, cases. Our results allow us to extract the heuristics used by the participants and to build a numerical simulation model that agrees very well with the experiments. Our findings have important implications for policymakers intending to promote specific, desired behaviors in a mobile population. Furthermore, we carry out an experiment with human subjects playing the Prisoner's Dilemma game in a diluted grid where people are able to move around. In contrast to previous results on purposeful rewiring in relational networks, we find no noticeable effect of mobility in space on the level of cooperation. Clusters of cooperators form momentarily but in a few rounds they dissolve as cooperators at the boundaries stop tolerating being cheated upon. Our results highlight the difficulties that mobile agents have to establish a cooperative environment in a spatial setting without a device such as reputation or the possibility of retaliation. i.e. punishment. Finally, we test experimentally the evolution of cooperation in social networks taking into ac- count a setting where we allow people to make or break links at their will. In this work we give particular attention to whether information on an individual's actions is freely available to poten- tial partners or not. Studying the role of information is relevant as information on other people's actions is often not available for free: a recruiting firm may need to call a job candidate's refer- ences, a bank may need to find out about the credit history of a new client, etc. We find that people cooperate almost fully when information on their actions is freely available to their potential part- ners. Cooperation is less likely, however, if people have to pay about half of what they gain from cooperating with a cooperator. Cooperation declines even further if people have to pay a cost that is almost equivalent to the gain from cooperating with a cooperator. Thus, costly information on potential neighbors' actions can undermine the incentive to cooperate in dynamical networks.

What role do just-world beliefs play in harmful responses to injustice?

Research suggests that employees sometimes retaliate and sometimes refrain from retaliation for the same reason, namely because they care about justice. In two studies, we seek to solve this apparent inconsistency. Drawing on just world theory, we argue that retaliatory, harmful behavioral strategies to deal with injustice are associated to individual differences in personal belief in a just world (personal BJW). In contrast, individual differences in believing that the world is just in general (general BJW) are linked to the inhibition of these reactions. As a consequence, the relation between injustice and harmful behaviors is stronger for people with a high personal BJW than for those with a low one. General BJW is associated with their inhibition such that the relation between injustice and harmful reactions is weaker for people with a high general BJW than for those with a low one. We found evidence for our hypotheses in a cross-sectional field study and an experiment. We discuss our findings in light of their implications for just-world theory and suggest avenues for future research integrating organizational justice literature.

James Monroe letter of marque, ca. 1812

James Monroe (1758-1831) was appointed Secretary of State by President James Madison in 1811. He remained in this position until March, 1817, with the exception of the period from October 1, 1814, to February 28, 1815, when he was ad interim Secretary of State. Monroe encouraged President James Madison and Congress to declare war on Great Britain, feeling it would be the most effective way to change offensive British policies. The United States declared war on June 17, 1812, after which he served as Secretary of War. Monroe later became President of the United States from 1817 until 1824.

James Monroe letter of marque, ca. 1812

A letter of marque addressed to Captain James Rogers, commander of the boat Retaliation, and signed by James Monroe, secretary of state. Letters of marquee provided legal authority for an armed vessel to capture enemy ships and commit acts which would otherwise constitute piracy. The letter has no date, but was likely created during the War of 1812, and authorizes the Captain to attack and capture enemy vessels.

Semisynthetic aminoglycoside antibiotics : toward biomimetic synthesis, evasion of bacterial resistance and reduced toxicity

Les antibiotiques aminoglycosidiques sont des agents bactéricides de grande valeur et d’efficacité à large spectre contre les pathogènes Gram-positifs et Gram-négatifs, dont plusieurs membres naturels et semisynthétiques sont importants dans l’histoire clinique depuis 1950. Des travaux crystallographiques sur le ribosome, récompensés par le prix Nobel, ont démontré comment leurs diverses structures polyaminées sont adaptées pour cibler une hélice d’ARN dans le centre de codage de la sous-unité 30S du ribosome bactérien. Leur interférence avec l’affinité et la cinétique des étapes de sélection et vérification des tARN induit la synthèse de protéines à basse fidélité, et l’inhibition de la translocation, établissant un cercle vicieux d’accumulation d’antibiotique et de stress sur la membrane. En réponse à ces pressions, les pathogènes bactériens ont évolué et disséminé une panoplie de mécanismes de résistance enzymatiques et d’expulsion : tels que les N acétyltransférases, les O phosphotransférases et les O nucleotidyltransférases qui ciblent les groupements hydroxyle et amino sur le coeur des aminoglycosides; des méthyl-transférases, qui ciblent le site de liaison ribosomale; et des pompes d’expulsion actives pour l’élimination sélective des aminoglycosides, qui sont utilisés par les souches Gram-négatives. Les pathogènes les plus problématiques, qui présentent aujourd’hui une forte résilience envers la majorité des classes d’antibiotiques sur le bord de la pan-résistance ont été nommés des bactéries ESKAPE, une mnémonique pour Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa et Enterobacteriaceae. La distribution globale des souches avec des mécanismes de résistance envers les standards cliniques aminoglycosides, tels que la tobramycine, l’amikacine et la gentamicine, est comprise entre 20 et 60% des isolées cliniques. Ainsi, les aminoglycosides du type 4,6-disubstitués-2-deoxystreptamine sont inadéquats comme thérapies anti-infectieuses à large spectre. Cependant, la famille des aminoglycosides 4,5-disubstitués, incluant la butirosine, la neomycine et la paromomycine, dont la structure plus complexe, pourrait constituter une alternative. Des collègues dans le groupe Hanessian et collaborateurs d’Achaogen Inc. ont démontré que certains analogues de la paraomomycine et neomycine, modifiés par désoxygénation sur les positions 3’ et 4’, et par substitution avec la chaîne N1-α-hydroxy-γ-aminobutyramide (HABA) provenant de la butirosine, pourrait produire des antibiotiques très prometteurs. Le Chapitre 4 de cette dissertation présente la conception et le développement d’une stratégie semi-synthétique pour produire des nouveaux aminoglycosides améliorés du type 4,5 disubstitués, inspiré par des modifications biosynthétiques de la sisomicine, qui frustrent les mécanismes de résistance bactérienne distribuées globalement. Cette voie de synthèse dépend d’une réaction d’hydrogénolyse de type Tsuji catalysée par palladium, d’abord développée sur des modèles monosaccharides puis subséquemment appliquée pour générer un ensemble d’aminoglycosides hybrides entre la neomycine et la sisomicine. Les études structure-activité des divers analogues de cette nouvelle classe ont été évaluées sur une gamme de 26 souches bactériennes exprimant des mécanismes de résistance enzymatique et d’expulsion qui englobe l’ensemble des pathogènes ESKAPE. Deux des antibiotiques hybrides ont une couverture antibacterienne excellente, et cette étude a mis en évidence des candidats prometteurs pour le développement préclinique. La thérapie avec les antibiotiques aminoglycosidiques est toujours associée à une probabilité de complications néphrotoxiques. Le potentiel de toxicité de chaque aminoglycoside peut être largement corrélé avec le nombre de groupements amino et de désoxygénations. Une hypothèse de longue date dans le domaine indique que les interactions principales sont effectuées par des sels des groupements ammonium, donc l’ajustement des paramètres de pKa pourrait provoquer une dissociation plus rapide avec leurs cibles, une clairance plus efficace et globalement des analogues moins néphrotoxiques. Le Chapitre 5 de cette dissertation présente la conception et la synthèse asymétrique de chaînes N1 HABA β substitutées par mono- et bis-fluoration. Des chaînes qui possèdent des γ-N pKa dans l’intervalle entre 10 et 7.5 ont été appliquées sur une neomycine tétra-désoxygénée pour produire des antibiotiques avancés. Malgré la réduction considérable du γ N pKa, le large spectre bactéricide n’a pas été significativement affecté pour les analogues fluorés isosteriques. De plus, des études structure-toxicité évaluées avec une analyse d’apoptose propriétaire d’Achaogen ont démontré que la nouvelle chaîne β,β difluoro-N1-HABA est moins nocive sur un modèle de cellules de rein humain HK2 et elle est prometteuse pour le développement d’antibiotiques du type neomycine avec des propriétés thérapeutiques améliorées. Le chapitre final de cette dissertation présente la proposition et validation d’une synthèse biomimétique par assemblage spontané du aminoglycoside 66-40C, un dimère C2 symétrique bis-imine macrocyclique à 16 membres. La structure proposée du macrocycle a été affinée par spectroscopie nucléaire à un système trans,trans-bis-azadiène anti-parallèle. Des calculs indiquent que l’effet anomérique de la liaison α glycosidique entre les anneaux A et B fournit la pré-organisation pour le monomère 6’ aldéhydo sisomicine et favorise le produit macrocyclique observé. L’assemblage spontané dans l’eau a été étudié par la dimérisation de trois divers analogues et par des expériences d’entre croisement qui ont démontré la généralité et la stabilité du motif macrocyclique de l'aminoglycoside 66-40C.

Inscripción del terrorismo en la agenda gubernamental estadounidense después de los ataques del 11 de septiembre de 2001

Este trabajo se enmarcará en la primera presidencia de George W. Bush y más específicamente entre el 11 de septiembre de 2001 cuando se dio el ataque a las torres gemelas y la invasión a Afganistán el 7 de octubre de este mismo año. En consecuencia lo que se busca con este estudio es demostrar que el gobierno estadounidense se ayuda de herramientas y elementos como la comunicación política, la fijación de agenda y el discurso para la inscripción del concepto terrorismo en la agenda gubernamental. Es así como genera un gran poder de influencia a nivel local logrando que los ciudadanos se tornen hacia el Estado y al mismo tiempo logra apoyo internacional generando el clima perfecto para legitimar la guerra anti-terrorista como una respuesta a los hechos ocurridos.

La incidencia del sistema de patentes estadounidense en la política de salud pública sudafricana 2000- 2012

El interés de este estudio de caso es explicar la incidencia del sistema de patentes estadounidense en la política de salud pública sudafricana del 2000 al 2012. Teniendo en cuenta los altos costos que este sistema impone en los precios de los medicamentos especialmente para tratar el VIH/SIDA y la malaria dos de los males que más aquejan a la población sudafricana. Se pretende explicar y establecer los cambios que ha implementado el gobierno sudafricano en su política de salud pública a través de la creación de una incipiente industria farmacéutica genérica que alivia en parte esta situación, pero que resulta insuficiente debido a su primordial interés de mantener relaciones cordiales con Estados Unidos antes que experimentar cualquier represalia como sucedió en India y Brasil.

Assédio Sexual nas Organizações e aplicação prática da Legislação : análise de Casos Reais

O assédio sexual deveria transformar-se numa preocupação, permanente para os médicos, advogados, magistrados, psicólogos, sociólogos, gestores de recursos humanos, administradores e diretores de empresas, e a sociedade em geral, de forma a manter os valores morais e profissionais. A sociedade atual preocupa-se muito mais com a ostentação de valores materiais visíveis, sendo o assédio sexual considerado como algo oculto, que as vítimas tentam esconder. A maioria das mulheres não denuncia o assédio sexual por vários medos, que alternam entre as represálias ou retaliações, de serem rebaixadas, de perderem o emprego, - já que dependem desse para sobreviver - de serem transferidas, de se expor ao ridículo frente aos colegas, familiares e amigas, de perderem a carta de referência, etc. Habitualmente, têm muitas dificuldades em falar, não só porque revivem algo desagradável que as incomoda psicologicamente, mas também porque não acreditam que existam recursos para tratar de maneira eficaz e eficiente o problema que as afeta dramaticamente.

El papel de Brasil en la geografía del comercio internacional y la efectividad del Sistema Multilateral de Comercio (Tema Central)

La Organización Mundial del Comercio (OMC) ha fortalecido y mejorado el sistema multilateral de comercio, surgido en los años siguientes al final de la Segunda Guerra Mundial, con el fin de garantizar la libre competencia entre los países miembros, eliminar las barreras al comercio internacional y permitir cada vez más el acceso de las empresas y de los consumidores a los mercados extranjeros de bienes y servicios.
