UM ESTUDO COMPARATIVO ENTRE OS INSTRUMENTOS DE PLANEAMENTO DE UM MUNICIPIO DE BRASIL E UMA AUTARQUIA EM CABO VERDE EM SEUS ASPECTOS ALOCATIVOS FISCAIS E SOCAIS

O presente trabalho descreve de forma lacónica o estudo comparado entre o município de Santa Cruz / Cabo Verde e o município de Borá/ Brasil- São Paulo. O objectivo central que guiou a elaboração deste trabalho, procurou essencialmente analisar através da pesquisa qualitativa da comparação, os instrumentos de planeamento municipal praticados nos dois municípios supra referidos nas áreas fiscais, alocativos e sociais, bem como a busca incessante pela complementaridade. Para efectivar a investigação proposta, apresentou-se primeiramente as questões gerais relacionados à fundamentação teórica necessária para a explicitação dos conteúdos da análise. Na sequência, fez-se uma exposição detalhada dos dados obtidos sobre a execução orçamentária apartir de pesquisa documental realizada no Municipio de Santa Cruz – Cabo Verde e do Municipio de Borá, São Paulo – Brasil. Após a incursão na execução orçamentaria de cada municipio que integrou a pesquisa, fez-se uma comparação entre os dados orçados com as realizadas. Além disso, investigou-se também a fundamentação legal da gestão orçamentária e financeira como meio de dotar o Município de Santa Cruz de mecanismo de controle e planeamento estratégico. Com base na análise, concluiu-se que existem realidades diferentes entre os municípios no que concerne a sua estrutura orçamental, suporte legal e também na forma de alocação dos recursos. Assim, as conclusões e recomendações direccionam o trabalho no sentido de oferecer subsídios para a melhoria do sistema de organização de uma estrutura orçamentária que melhor sirva os dois municípios.

La Alfabetización digital mediática y el reto de las TIC en Colombia : diagnóstico y análisis de las principales iniciativas educomunicativas en el escenario 2.0

Històricament la inserció de Colombia a les TIC i al desenvolupament que aquestes comporten va ser lenta. Tot i això, als últims anys s'han desenvolupat projectes de infraestructura i apropiació tecnològica a grans velocitats. En aquest escenari la educomunicació ha avançat de manera formidable i la web colombiana comença a nodrir-se de continguts abundants i de qualitat per a l'educació. Aquest treball examina les principals iniciatives 2.0 per a l'educomunicació i dóna un diagnòstic sobre la seva funcionalitat (progressos i carències). Finalment, dóna una serie de recomanacions per al correcte ús de les eines que ofereix la web 2.0

From severance pay to self-insurance: Effects of severance payments savings accounts in Colombia

In 1990 Colombia replaced its traditional system of severance paymentswith a new system of severance payments savings accounts (SPSAs). Althoughseverance payments often are justified on the grounds that they provideinsurance against earnings loss, they also increase costs for employersand distort employment decisions. The impact of severance payments dependslargely on how much of the costs to employers can be shifted to workers.The theoretical analysis in this paper shows that, in contrast to atraditional system of severance payments, the system of SPSAs facilitatesthe shifting of severance payments costs to workers in the form of lowerwages. Empirical results using the Colombian National Household Surveysindicate that the introduction of SPSAs shifted around 80% of the totalseverance payments contributions to wages and had a positive effect onweekly hours. Results using the 1997 Colombian Living Standards MeasurementSurvey suggest that, although SPSAs in part replaced employer insurancewith self-insurance, SPSAs continue to play a consumption smoothing rolefor the non-employed.

The effects of structural reforms on productivity and profitability enhancing reallocation: Evidence from Colombia

Estimates for the U.S. suggest that at least in some sectors productivity enhancing reallocationis the dominant factor in accounting for producitivity growth. An open question, particularlyrelevant for developing countries, is whether reallocation is always productivity enhancing. Itmay be that imperfect competition or other barriers to competitive environments imply that thereallocation process is not fully e?cient in these countries. Using a unique plant-levellongitudinal dataset for Colombia for the period 1982-1998, we explore these issues byexamining the interaction between market allocation, and productivity and profitability.Moreover, given the important trade, labor and financial market reforms in Colombia during theearly 1990's, we explore whether and how the contribution of reallocation changed over theperiod of study. Our data permit measurement of plant-level quantities and prices. Takingadvantage of the rich structure of our price data, we propose a sequential mehodology to estimateproductivity and demand shocks at the plant level. First, we estimate total factor productivity(TFP) with plant-level physical output data, where we use downstream demand to instrumentinputs. We then turn to estimating demand shocks and mark-ups with plant-level price data, usingTFP to instrument for output in the inversedemand equation. We examine the evolution of thedistributions of TFP and demand shocks in response to the market reforms in the 1990's. We findthat market reforms are associated with rising overall productivity that is largely driven byreallocation away from low- and towards highproductivity businesses. In addition, we find thatthe allocation of activity across businesses is less driven by demand factors after reforms. Wefind that the increase in aggregate productivity post-reform is entirely accounted for by theimproved allocation of activity.

Thermogenic response to an oral glucose load in man: comparison between young and elderly subjects.

To investigate the effect of age and change in body composition on the increase in energy expenditure consecutive to the ingestion of a 75-g glucose load, respiratory exchange measurements were performed on 24 subjects, 12 elderly (mean +/- SEM, 73 +/- 1 yr) and 12 young (25 +/- 1 yr). The body weight was comparable, 62 +/- 2 kg in the elderly group vs 61 +/- 3 in the young, but the body fat content of the elderly group was significantly greater than that of the young (29 +/- 2% vs 19 +/- 2%, p less than 0.001). The elderly group presented a slight glucose intolerance according to the World Health Organization (WHO) criteria, with a 120-min plasma glucose of 149 +/- 9 mg/dl (p less than 0.005 vs young). The postabsorptive resting energy expenditure (REE) was 0.83 +/- 0.03 kcal/min in the elderly group vs 0.98 +/- 0.04 in the young (p less than 0.02); this decrease of 15% was mainly related to the decrease in fat free mass (FFM) in the elderly group, which averaged 14%. The difference was not significant when REE was expressed per kg FFM. The glucose-induced thermogenesis (GIT) expressed as percent of energy content of the load was 6.2 +/- 0.6% in the elderly group and 8.9 +/- 0.9% in the young (p less than 0.05). It is concluded that the glucose-induced thermogenesis is decreased in elderly subjects. However, when expressed per kg FFM, the increment in energy expenditure (EE), in response to the glucose load, is not different in elderly subjects, suggesting that the decrease of thermogenesis may be attributed to the age-related decrease in FFM.

Familias Estruturadas e Sub-Familias de Matrizes

Desenvolvemos modelos para matrizes estocásticas simétricas com matriz média com característica um. Estas matrizes desempenham um papel relevante em muitas situações interessantes, por exemplo em problemas de componentes principais com primeira componente dominante. Mostramos como ajustar e validar tais modelos e como medir o respectivo grau de Ajustamento através de um estudo de simulações para evidenciar o bom comportamento dos estimadores obtidos. Esse bom comportamento verifica-se quando o primeiro valor próprio da matriz média e suficientemente preponderante. Utilizando a linearidade assimptótica foi possível testar se esta condição se verifica. Al em de modelos para matrizes quase escalares estudamos famílias estruturadas de modelos, cujas matrizes correspondem aos tratamentos de um delineamento base. Consideramos ainda famílias de modelos divididas em subfamílias que correspondem a esses tratamentos. Estamos sobretudo interessados em modelos base com estrutura ortogonal. Apresentamos essa estrutura e mostramos como aplicar esses modelos no estudo de famílias estruturadas. Damos uma aplicação dos nossos resultados a metodologia Statis, concretamente aos resultados de eleições autárquicas em Portugal Continental. Nesta aplicação utilizamos o facto destes modelos serem aplicáveis a primeira e segunda etapas desta metodologia. Assim, consideramos um par de famílias decompostas, em subfamílias que correspondem aos tratamentos do mesmo delineamento base. A primeira família corresponde a primeira etapa da metodologia Statis, e a segunda família corresponde a segunda etapa da mesma metodologia. Estudamos a heterogeneidade das subfamílias de ambas as famílias de modelos. Concluímos que a ordenação das subfamílias a partir da respectiva heterogeneidade se mantém da primeira para a segunda etapa.

Escarabajos coprófagos (Coleoptera, Scarabaeoidea) del Parque Nacional Los Estoraques (Norte de Santander, Colombia)

En este trabajo se presenta información sobre los escarabajos coprófagos del Área Natural Única Los Estoraques (ANUE), Departamento de Norte de Santander, Colombia. Los muestreos fueron realizados durante los meses de febrero a diciembre del año 2002 en cuatro sitios con diferente grado de intervención, suministrando la captura de 10,538 individuos. Los sitios muestreados correspondieron a bosque seco premontano y bosque montañoso húmedo con diferentes grados de intervención. 16 especies de Scarabaeinae conformaron el 89% de las ejemplares colectados, el 11% restante (3 especies) fue conformado por Hibosóridos. La totalidad de las especies se completo en el quinto muestreo. Se registró diferencia significativa en la riqueza y abundancia entre los sitios (P <0,05), funcionando las zonas de bosque montañoso humedo como un solo ensamblaje. Las abundancias de las especies no muestran correlación con la pluviosidad. Se reportan por primera vez siete especies para el departamento y se amplia el rango altitudinal conocido en Colombia para cuatro.

Synanthropy and ecological aspects of Muscidae (Diptera) in a tropical dry forest ecosystem in Colombia

The synanthropic index and other ecological aspects of the Muscidae family were evaluated through simultaneous monthly sampling in three different environments (urban, rural and forest) using van Someren-Rydon traps baited with human faeces, chicken viscera and decomposing fish and onion. Four traps were set up in each environment (one per bait item) for 48 hours per month, with samples taken every 12 hours. A total of 5726 specimens were collected, belonging to 19 species and 13 genera. Brontaea normata (+99,9), Brontaea quadristigma (+96,9), Synthesiomyia nudiseta (+96,5), Ophyra aenescens (+96,2), Musca domestica (+95,7) and Atherigona orientalis (+93,8) had the highest synanthropic indices, showing a marked preference for human environments. The most abundant species were B. normata (24,31%), Biopyrellia bipuncta (20,60%) and Pseudoptilolepis nigripoda (15,82%), the latter two showed a preference for uninhabited areas. A total of 11 new records for Colombia were found: Ophyra aenescens, Cyrtoneuropsis pararescita, Morellia basalis, Neomuscina dorsipuncta, Biopyrellia bipuncta, Pseudoptilolepis nigripoda, Neomuscina instabilis, Neomuscina currani, Polietina orbitalis, Neomuscina pictipennis and Cyrtoneuropsis maculipennis. Except for the first four species, the remainder presented negative synantrophy indexes (from minor to major), which would allow to use them as ecological indicators of the disturbance degree of dry forests in Colombia.

The labor market effects of payroll taxes in a middle-income country: Evidence from Colombia

We use a panel of manufacturing plants from Colombia to analyze how the risein payroll tax rates over the 1980 s and 1990 s affected the labor market.Our estimates indicate that formal wages fall by between 1.4% and 2.3% as aresult of a 10% rise in payroll taxes. This 'less-than-full-shifting' islikely to be the result of weak linkages between benefits and taxes and thepresence of downward wage rigidities induced by a binding minimum wage inColombia. Because the costs of taxation are only partly shifted fromemployers to employees, employment should also fall. Our results indicatethat a 10% increase in payroll taxes lowered formal employment by between4% and 5%. In addition, we find less shifting and larger disemploymenteffects for production than non-production workers. These results suggestthat policies aimed at boosting the relative demand of low-skill workers byreducing social security taxes on those with low earnings may be effectivein a country like Colombia, especially if tax cuts are targeted to indirectbenefits.

A new species of Giovanella Bonatto (Diptera, Calliphoridae, Mesembrinellinae) from Colombia

A new species of Giovanella Bonatto (Diptera, Calliphoridae, Mesembrinellinae) from Colombia. The Mesembrinellinae are exclusively Neotropical, with 33 nominal species distributed in nine genera. Only the genera Mesembrinella, Eumesembrinella, Huascaromusca and Laneella had until now been recorded in Colombia. In this work we present a new species of Giovanella Bonatto, 2005, genus with only one species, G. bolivar Bonatto, differing from the new species G. carvalhoi sp. nov., in the characters: legs entirely dark chestnut; thorax with dorsocentrals setae 1:2; abdomen with T5 with discal bristles poorly differentiated; T6 symmetric and paraphallus not extended and with denticules. Giovanella carvalhoi sp. nov. is from Cordillera Oriental, from the Departments of Caquetá (Amazonian foothills) and Santander, Colombia, collected between 22002400 m., and associated with decomposing organic matter. A key for the identification of males and females of the two species of Giovanella, illustrations of the genitalia and photographs of male and female of new species are also presented.
