EM TEMPOS GLOBAIS, UM “NOVO” LOCAL: a Ford na Bahia

O artigo analisa a dinâmica da Região Metropolitana de Salvador (RMS) a partir da implantação da Ford, discutindo a perspectiva do ‘lugar’ (a periferia metropolitana), dentro de uma relação assimétrica com os negócios globais na era da flexibilidade. O texto caracteriza o complexo Ford de Camaçari a partir da reestruturação produtiva e das mudanças na organização e funcionamento dos territórios e, na segunda parte, seus impactos sobre a periferia metropolitana de Salvador. Na conclusão demonstra que as mesmas circunstâncias que permitiram a vinda da montadora para Camaçari constrangem as ambições originais de melhor equacionamento entre crescimento econômico e progresso social: a flexibilidade dos novos arranjos, que tornam os espaços periféricos estratégicos, compromete o “enraizamento” do investimento; a “produção enxuta”, exígua de emprego e diligente na sua precarização, inibe os benefícios sociais. PALAVRAS CHAVE: reestruturação produtiva, mercado de trabalho, indústria automobilística, periferia metropolitana, segregação socioespacial. IN GLOBAL TIMES, A “NEW” PLACE: Ford in Bahia Ângela Franco This paper makes an analysis of the dynamics of the Metropolitan Area of Salvador (in Portuguese, RMS) starting from the implantation of Ford, discussing the perspective of the ‘local’ (the metropolitan periphery), inside of an asymmetrical relationship with global businesses in the age of flexibility. The Ford Automotive Compound is caracterized in the first part of the paper from its productive reestructuring and changes in the organization and work of territories, and, in the second part, from its impact on the the metropolitan periphery from Salvador. In its conclusion it demonstrates that the same circumstances that allowed the arrival of the automotive maker in Camaçari constrain the original ambitions of better ratio between economical growth and social progress: the flexibility of the new automotive production methods, making peripheric spaces strategic, compromises on the permanence of the investments; and the “streamlined production”, easy on job production and hard on job flexibilization inhibit social benefits. KEYWORDS: productive restructuring, job market, automobile industry, metropolitan periphery, socioespatial segregation. EN PERIODE DE MONDIALISATION, UN “NOUVEAU” LOCAL: Ford à Bahia Ângela Franco Cet article traite de l’analyse de la dynamique de la Région Métropolitaine de Salvador (RMS), à partir de l’implantation de l’usine Ford. On y discute de la perspective du “lieu” (la périphérie métropolitaine), dans une relation asymétrique avec les affaires globales à une époque de flexibilité. On y caractérise le complexe Ford de Camaçari à partir de la restructuration productive et des changements dans l’organisation et le fonctionnement des territoires. Ses impacts sur la périphérie métropolitaine de Salvador sont présentés dans la deuxième partie. En conclusion, on y démontre que ce sont les mêmes circonstances qui ont permis l’arrivée de l’usine de montage à Camaçari qui représentent une contrainte pour les ambitions qui, à l’origine, voulaient atteindre une meilleure équation entre la croissance économique et le progrès social. La flexibilité de ces nouveaux arrangements, qui rendent les espaces périphériques stratégiques, compromet “l’enracinement” des investissements, la “production exiguë”, l’exiguïté des emplois et la diligence dans leur précarisation, elle inhibe les avantages sociaux. MOTS-CLÉS: restructuration productive, marché du travail, industrie automobile, périphérie métropolitaine, ségrégation sociale et spatiale.

Gender effects on esophageal motility

It has been suggested that there are no gender effects on esophageal motility. However, in previous studies the subjects did not perform multiple swallows and the quantitative features of esophageal contractions were not evaluated. In order to investigate the gender effects on esophageal motility we studied 40 healthy normal volunteers, 20 men aged 37 ± 15 years (mean ± SD), and 20 women aged 38 ± 14 years. We used the manometric method with an eight-lumen polyvinyl catheter and continuous perfusion. The upper and lower esophageal sphincter pressures were measured by the rapid pull-through method. With the catheter positioned with one lumen opening in the lower esophageal sphincter, and the others at 5, 10 and 15 cm above the sphincter, ten swallows of a 5-ml water bolus alternated with ten dry swallows were performed. Statistical analysis was done by the Student t-test and Mann-Whitney test. Gender differences (P<0.05) were observed for wet swallows in the duration of contractions 5 cm above the lower esophageal sphincter (men: 3.7 ± 0.2 s, women: 4.5 ± 0.3 s, mean ± SEM), and in the velocity of contractions from 15 to 10 cm above the lower esophageal sphincter (men: 4.7 ± 0.3 cm/s, women: 3.5 ± 0.2 cm/s). There was no difference (P>0.05) in sphincter pressure, duration and percentage of complete lower esophageal sphincter relaxation, amplitude of contractions, or in the number of failed, multipeaked and synchronous contractions. We conclude that gender may cause some differences in esophageal motility which, though of no clinical significance, should be taken into consideration when interpreting esophageal motility tests
