This thesis describes the development and use of a goal programming methodology for the evaluation of public housjng strategies in Mexico City, The methodology responds to the need to incorporate the location, size and densities of housing projects on the one hand, and "external" constraints such as the ability of low income families to pay for housing, and the amounts of capital and land available, on the other. The provision of low cost housing by public housing agencies in Mexico City is becoming increasingly difficult because there are so many constraints to be met and overcome, the most important of which is the ability of families to pay for housing. Other important limiting factors are the availability of capital and of land plots of the right size in desired locations. The location of public housing projects is significant because it determines the cost and pattern of work trips, which in a metropolitan area such as Mexico City are of considerable importance to both planners and potential. house owners. In addition, since the price of land is closely related to its location, the last factor is also significant in determining the price of the total housing package. Consequently there is a major trade-off between a housing strategy based on the provision of housing at locations close to employment, and the opposite one based on the provjsion of housjng at locations where employment accessibility is poorer but housing can be provided at a lower price. The goal programming evaluation methodology presented in this thesis was developed to aid housing planners to evaluate housing strategies which incorporate the issues raised above,

This dissertation examines local governments' efforts to promote economic development in Latin America. The research uses a mixed method to explore how cities make decisions to innovate, develop, and finance economic development programs. First, this study provides a comparative analysis of decentralization policies in Argentina and Mexico as a means to gain a better understanding of the degree of autonomy exercised by local governments. Then, it analyzes three local governments each within the province of Santa Fe, Argentina and the State of Guanajuato, Mexico. The principal hypothesis of this dissertation is that if local governments collect more own-source tax revenue, they are more likely to promote economic development and thus, in turn, promote growth for their region. ^ By examining six cities, three of which are in Santa Fe—Rosario, Santa Fe (capital) and Rafaela—and three in Guanajuato—Leon, Guanajuato (capital) and San Miguel de Allende, this dissertation provides a better understanding of public finances and tax collection efforts of local governments in Latin America. Specific attention is paid to each city's budget authority to raise new revenue and efforts to promote economic development. The research also includes a large statistical dataset of Mexico's 2,454 municipalities and a regression analysis that evaluates local tax efforts on economic growth, controlling for population, territorial size, and the professional development. In order to generalize these results, the research tests these discoveries by using statistical data gathered from a survey administered to Latin American municipal officials. ^ The dissertation demonstrates that cities, which experience greater fiscal autonomy measured by the collection of more own-source revenue, are better able to stimulate effective economic development programs, and ultimately, create jobs within their communities. The results are bolstered by a large number of interviews, which were conducted with over 100 finance specialists, municipal presidents, and local authorities. The dissertation also includes an in-depth literature review on fiscal federalism, decentralization, debt financing and local development. It concludes with a discussion of the findings of the study and applications for the practice of public administration.^

This dissertation examines Mexico City’s material politics of print—the central actors engaged in making print, their activities and relationships, and the legal, business, and social dimensions of production—across the nineteenth century. Inside urban printshops, a socially diverse group of men ranging from manual laborers to educated editors collaborated to make the printed items that fueled political debates and partisan struggles in the new republic. By investigating how print was produced, regulated, and consumed, this dissertation argues that printers shaped some of the most pressing conflicts that marked Mexico’s first formative century: over freedom of expression, the role of religion in government, and the emergence of liberalism. Printers shaped debates not only because they issued texts that fueled elite politics but precisely because they operated at the nexus where new liberal guarantees like freedom of the press and intellectual property intersected with politics and patronage, the regulatory efforts of the emerging state, and the harsh realities of a post-colonial economy.

Historians of Mexico have typically approached print as a vehicle for texts written by elites, which they argue contributed to the development of a national public sphere or print culture in spite of low literacy levels. By shifting the focus to print’s production, my work instead reveals that a range of urban residents—from prominent printshop owners to government ministers to street vendors—produced, engaged, and deployed printed items in contests unfolding in the urban environment. As print increasingly functioned as a political weapon in the decades after independence, print production itself became an arena in struggles over the emerging contours of politics and state formation, even as printing technologies remained relatively unchanged over time.

This work examines previously unexplored archival documents, including official correspondence, legal cases, business transactions, and printshop labor records, to shed new light on Mexico City printers’ interactions with the emerging national government, and reveal the degree to which heated ideological debates emerged intertwined with the most basic concerns over the tangible practices of print. By delving into the rich social and cultural world of printing—described by intellectuals and workers alike in memoirs, fiction, caricatures and periodicals— it also considers how printers’ particular status straddling elite and working worlds led them to challenge boundaries drawn by elites that separated manual and intellectual labors. Finally, this study engages the full range of printed documents made in Mexico City printshops not just as texts but also as objects with particular visual and material qualities whose uses and meanings were shaped not only by emergent republicanism but also by powerful colonial legacies that generated ambivalent attitudes towards print’s transformative power.

Recent emphasis on ecosystem approaches to fisheries management renews interest in, and the need for, trophic information about fish communities. A program was started in 1980 at the National Marine Fisheries Service Galveston Laboratory to develop a trophic database for continental shelf fishes. Collections were made during 1982-1983 that were processed but never published, yet the data remain valid today for historical purposes and for delimiting food web components within ecosystem assessments. I examined spring, summer, and fall foods in offshore populations of nine common species of trawl-susceptible fishes, with particular reference to predation on commercial penaeid shrimps (Farfantepenaeus and Litopenaeus). Diets were evaluated with the Index of Relative Importance (IRI) which combines the occurrence, number, and weight of each food item. Bank sea bass (Centropristis ocyurus) and bighead searobin (Prionotus tribulus) primarily consumed crabs, more so by larger than smaller fish. Inshore lizardfish (Synodus foetens) was almost entirely piscivorous. Ocellated flounder (Ancylopsetta ommata) consumed fishes, crabs, and stomatopods. Dwarf sand perch (Diplectrum bivittatum), blackwing searobin (Prionotus rubio), rock sea bass (Centropristis philadelphica), southern kingfish (Menticirrhus americanus), and red snapper (Lutjanus campechanus) fed mainly on shrimps. Most fish diets varied with respect to size (age), time of day, area sampled, depth, or season. Rimapenaeus and Sicyonia were the most frequently identified shrimp genera - only five Farfantepenaeus and no Litopenaeus were identified in almost 4,300 fish stomachs. I also examined gonadal development and documented fish length-weight relationships. Ripe gonads were most frequently found during summer in dwarf sand perch, during fall in ocellated flounder and bighead searobin, and during spring for other species, except no ripe red snapper or bank sea bass were collected. Rock sea bass was found to be a protogynous hermaphrodite, while dwarf sand perch is a synchronous hermaphrodite. Only ocellated flounder and southern kingfish exhibited sex-related differences in length-weight relationships. (PDF contains 40 pages.)

This study analyses the narrative elements of a little-known report into anti-venereal trials written by an Irish military physician-surgeon, Daniel O'Sullivan (1760–c.1797). It explores the way in which O'Sullivan as the narrator of the Historico-critical report creates medical heroes and anti-heroes as a means to criticise procedures initiated by staff in the Hospital General de San Andrés, Mexico City. The resulting work depicts a much less positive picture of medical trials and hospital authorities in this period than has been recorded to date, and provides a critical and complicated assessment of one of Spain's leading physicians of the nineteenth century, Francisco Javier Balmis (1753–1819).

PURPOSE:

To report determinants of outcomes and follow-up in a large Mexican pediatric cataract project.

SETTING:

Hospital Luis Sanchez Bulnes, Mexico City, Mexico.

METHODS:

Data were collected prospectively from a pediatric cataract surgery program at the Hospital Luis Sanchez Bulnes, implemented by Helen Keller International. Preoperative data included age, sex, baseline visual acuity, type of cataract, laterality, and presence of conditions such as amblyopia. Surgical data included vitrectomy, capsulotomy, complications, and use of intraocular lenses (IOLs). Postoperative data included final visual acuity, refraction, number of follow-up visits, and program support for follow-up.

RESULTS:

Of 574 eyes of 415 children (mean age 7.1 years +/- 4.7 [SD]), IOLs were placed in 416 (87%). At least 1 follow-up was attended by 408 patients (98.3%) (mean total follow-up 3.5 +/- 1.8 months); 40% of eyes achieved a final visual acuity of 6/18 or better. Children living farther from the hospital had fewer postoperative visits (P = .04), while children receiving program support had more visits (P = .001). Factors predictive of better acuity included receiving an IOL during surgery (P = .04) and provision of postoperative spectacles (P = .001). Predictive of worse acuity were amblyopia (P = .003), postoperative complications (P = .0001), unilateral surgery (P = .0075), and female sex (P = .045).

CONCLUSIONS:

The results underscore the importance of surgical training in reducing complications, early intervention before amblyopia (observed in 40% of patients) can develop, and vigorous treatment if amblyopia is present. The positive impact of program support on follow-up is encouraging, although direct financial support may pose a problem for sustainability. More work is needed to understand reasons for worse outcomes in girls.

Cette thèse analyse la capacité d’action collective des populations marginalisées situées respectivement dans un bidonville appelé Cité de l’Éternel à Port-au-Prince (Haïti) et dans des campements à la Sierra Santa Catarina, Iztapalapa (Mexico). À Port-au-Prince, avant la chute de la dictature des Duvalier, des «tontons macoutes» envahirent un terrain situé en bordure du quai de la capitale, près du boulevard Harry Truman. Après s’y être installés, ils ont procédé à la vente de parcelles destinées à la construction de logement à des particuliers. Mais après la chute de Jean-Claude Duvalier, en 1986, des gens de la populace en ont profité pour envahir ce qui restait de ces terrains marécageux. Après l’occupation, ils se sont organisés pour défendre collectivement leur propriété avant d’entreprendre, par la suite, des démarches pour y amener des services et obtenir la régularisation de leur situation sur ces territoires. À la Sierra Santa Catarina, des populations conduites par des militants d’un Front populaire ont occupé des terrains situés au pied d’une montagne de sable afin d’accéder à la propriété et de construire leur demeure. À l’instar des populations de la Cité, ces gens se sont organisés pour aménager des espaces, y ériger des logements provisoires, monter la garde afin de ne pas être déguerpis par les forces de police. Tout en travaillant pour accéder à leur manière aux services de base, elles entreprennent des actions auprès des institutions publiques afin d’obtenir la régularisation de leur situation. Par rapport à la capacité d’action collective de ces populations, les théories sociologiques sont divisées. D’un côté, certains auteurs soutiennent la thèse de l’incapacité de ces populations d’avoir des intérêts collectifs et d’agir en conséquence. Selon eux, sans une médiation sociale ou à défaut d’une agrégation et d’une représentation politiques, ces populations sont incapables d’avoir une subjectivité collective. De l’autre, des auteurs pensent qu’à partir des liens d’amitié de parenté et de voisinage, indépendamment de leurs situations socioéconomiques, ces populations peuvent créer des stratégies de subsistance et de luttes qui leur permettent de trouver des solutions à des problèmes tant individuels que collectifs. S’agissant des populations qui envahissent des terrains en milieu urbain pour habiter, les actions de ces gens là sont définis déjà comme une forme d’action collective inscrite dans des rapports sociaux qui se caractérisent par la différenciation entre les groupes sociaux dans l’accès à la propriété. Ainsi, leurs revendications de reconnaissance et de régularisation auprès des instances étatiques sont déterminées par leur mode d’accès aux biens et aux richesses inégalement réparties en Haïti et au Mexique. Les populations des deux territoires ont entrepris diverses démarches auprès de certaines institutions et réalisé des actions collectives soit pour amener des services de base tels que l’eau et l’électricité, soit pour obtenir de l’État la reconnaissance des territoires envahis, c’est-à-dire leur jonction à la cartographie de la ville. Cette reconnaissance implique non seulement l’installation des services réguliers au bénéfice de la population mais aussi l’octroi à chaque propriétaire de son titre de propriété. Si dans le cas de la Sierra Santa Catarina les démarches sont entreprises auprès des institutions publiques, dans celui de Port-au-Prince, ce sont les ONG ou les agence de coopération qui sont touchées et qui fournissent certains services à la population conformément à la priorité de leurs bailleurs de fonds. Les interventions auprès de l’État se font plutôt dans le but d’obtenir une autorisation de fonctionnement d’une association locale. Il ressort des approches théoriques et des actions collectives réalisées par ces populations qu’on ne peut pas dire qu’elles sont incapables d’avoir une subjectivité collective et des intérêts communs sans une agrégation et une représentation politique. À partir de différents liens entre les individus, des associations sont créées lesquelles permettent d’établir une médiation entre les populations et d’autres organismes. Dans le cas des campements, les actions collectives sont certainement mises à contribution par quelques leaders. Cela participe de toute une tradition politique au Mexique. Néanmoins, dans certains campements, des populations parviennent à tenir tête jusqu’à révoquer certains leaders. Au-delà de leur situation socioéconomique, de l’emprise de certains dirigeants de campement, de l’indifférence de l’État (dans le cas de Port-au-Prince, notamment), ces populations font preuve d’une étonnante capacité critique de leur situation tant dans leurs relations avec les dirigeants des associations et des campements que par rapport à l’État. Ceci pourrait soulever des doutes quant à la possibilité qu’elles soient réellement ou inconsciemment manipulées. Cela suggère la possibilité d’actions collectives autonomes de portée critique là où les circonstances le permettent Mots clés : Marginalisation, action collective, reconnaissance, Débrouille, capacité critique, bidonvilles, instrumentalisation politique, reconnaissance fragmentée.

La ville préhispanique de Cantona, située dans la vallée d’Oriental dans l’état de Puebla au Mexique, atteignit sa première apogée culturelle entre 150 av. J.C. et 600/650 A.D. Durant cette période, des complexes cérémoniaux comprenant des groupes de pyramides-temples et des terrains de jeu de balle furent construits. Ces installations servirent au déroulement de nombreux rites au cours desquels les victimes de sacrifices étaient décapitées, démembrées, décharnées, écorchées, bouillies, brûlées et, dans certains cas, consommées. D’autres traitements du corps humain comportent l’inhumation d’individus en position assise et repliés sur eux-mêmes. Pour mieux comprendre le traitement mortuaire rituel des corps humains à Cantona, les découvertes faites sur place sont comparées aux données datant de la même époque obtenues dans trois régions voisines : la vallée de Mexico, Puebla-Tlaxcala et le golfe du Mexique. A partir de ces renseignements, on peut en déduire que la majorité des découvertes faites à Cantona sont les restes des dépouilles et offrandes provenant de rites destinés à la communication avec les dieux et à l’obtention de la fertilité, tandis que les dépouilles des individus en position assise appartiennent à des prêtres ou à des personnages religieux.
