Estimadores compuestos en estadística regional: aplicación para la tasa de variación de la ocupación en la industria

This work is part of a project studying the performance of model basedestimators in a small area context. We have chosen a simple statisticalapplication in which we estimate the growth rate of accupation for severalregions of Spain. We compare three estimators: the direct one based onstraightforward results from the survey (which is unbiassed), and a thirdone which is based in a statistical model and that minimizes the mean squareerror.

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.

Patentes, regulación de precios e innovación en la industria farmacéutica

The trade-off between property rights/price regulation and innovation depends on countrycharacteristics and drug industry specificities. Access to drugs and innovation can bereconciled by seven ways that, among others, include: public health strengthening in thecountries with the largest access problems (those among the poor with the weakestinstitutions); public and private aid to make attractive R&D on neglected diseases; pricediscrimination with market segmentation; to require patent owners to choose eitherprotection in the rich countries or protection in the poor countries (but not both).Regarding price regulation, after a review of theoretical arguments and empirical evidence,seven strategies to reconcile health and industrial considerations are outlined, including:mitigation of the medical profession dependence on the pharmaceutical industry; considerationof a drug as an input of a production process; split drug authorization from public fundingdecisions; establish an efficiency minimum for all health production inputs; and stop theEuropean R&D hemorrhagia.

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.

Insects associated with tropical foliage produced in the coffee growing region of Colombia

We conducted a survey of insects and pest management practices on 34 farms growing ornamental tropical foliage plants in the central coffee region of Colombia over two years. Tropical foliage provided habitat for a diverse range of insects. In total, phytophagous or detritivorous insects from six orders, 40 families and 62 genera were collected. The most common were Hemiptera (29 genera from 16 families), followed by Coleoptera (17 genera from 4 families), Diptera (5 genera from 5 families), Lepidoptera (5 genera from 4 families), Hymenoptera (3 genera from 2 families) and Orthoptera (2 genera from 2 families). The most common phytophagous species were leaf cutting ants (Atta and Acromyrmex spp.), leaf beetles (Chrysomelidae), leafhoppers (Cicadellidae), stinkbugs (Pentatomidae), squash bugs (Coreidae), tree hoppers (Membracidae) and plant hoppers (Fulgoridae). Beneficial insects identified from tropical foliage included predators and parasitoids amongst 5 orders, 12 families and 22 genera. The most abundant were predators among the Coccinellidae, Chrysopidae, Reduviidae, Lycidae and Formicidae but only low numbers of parasitoids (Ichneumonidae, Braconidae and Tachinidae) were collected. A pest management questionnaire given to growers revealed a preponderance of reliance on broad spectrum insecticides with a smaller number of growers (approximately one third) also using some biological control methods. Our survey contributes basic information regarding diversity of Neotropical insects associated with ornamental foliage plants.

La comunicación del conocimiento científico en la Universidad de los niños EAFIT. Medellín – Colombia

Este proyecto de investigación se ubica en el tópico de la comunicación de la ciencia y la apropiación del conocimiento científico en las “Universidades de los niños”, programas que buscan acercar el quehacer investigativo de las instituciones de educación superior a niños (7 -12 años) y jóvenes (13 – 16 años).La investigación se realizará sobre un caso de estudio particular: la Universidad de los niños EAFIT de Medellín (Colombia), al ser el único programa registrado en Latinoamérica en la Red de Universidades de los niños Europea (EUCU.NET). El propósito en primer lugar, es analizar, bajo la descripción de las interacciones comunicativas que allí se instauran -entre los niños y jóvenes, los estudiantes universitarios que cumplen el papel de talleristas, y los profesores investigadores de la Universidad-, si se percibe una motivación para apropiarse del conocimiento científico, lo que significa tener un papel más activo y propositivo en el intercambio de saberes.Y en segundo lugar, analizar las percepciones de los participantes respecto a las diferencias entre la manera de abordar el conocimiento bajo la propuesta pedagógica y metodológica de los colegios y la planteada por la Universidad de los niños EAFIT.Al ser reciente la aparición de este fenómeno educativo y social de la Universidad de los niños en el continente europeo, es poca la literatura académica publicada. Por ello, tener un análisis del caso particular de Colombia, dará mayores variables sociales y culturales que podrán ser un insumo para la construcción de aristas teóricas sobre el mismo.Este trabajo final corresponde al Máster de Estudios Avanzados en Comunicación y está estructurado bajo la modalidad de proyecto investigativo para la elaboración de la tesis doctoral, que espera ser realizada en el programa de Doctorado en Comunicación Social de esta universidad.

Review of Thompsoniella Guimarães with description of a new species from Colombia (Diptera, Calliphoridae, Mesembrinellinae)

Review of Thompsoniella Guimarães with description of a new species from Colombia (Diptera, Calliphoridae, Mesembrinellinae). The Mesembrinellinae (Diptera, Calliphoridae) are exclusively Neotropical with nine genera comprising 36 recognized species, including the genus Thompsoniella Guimarães with a single species, T. anomala Guimarães. We describe a new species, Thompsoniella andina sp. nov., from the Departments of Antioquia and Caldas, Colombia (Cordillera Central of the Andes, between 2600 - 2700 m) and redescribe T. anomala. A key to the nine genera of Mesembrinellinae and a key to the males of the two species of Thompsoniella are provided. Color photographs to illustrate the two species of Thompsoniella and drawings of the male genitalia of both species are also provided. Here we record Thompsoniella for the first time in Colombia.

Preliminary study of insects associated to indoor body decay in Colombia

Preliminary study of insects associated to indoor body decay in Colombia. This is the first report studying insects associated to indoor body decay process of a white pig (Sus scrofa) (Artiodactyla, Suidae) in a controlled indoor environment in an urban area of Florencia city, Amazonia Piedmont, Colombia. For a period of 54 days, 9,220 individuals (immature and adults), distributed in 3 orders, 5 families, 10 genera, and 10 species were collected using entomological nets and tweezers. Five decaying stages are described (fresh, bloated, active decay, advanced decay and remains). During the fresh stage we recorded Cochliomyia macellaria (Fabricius, 1775), Chrysomya albiceps (Wiedemann, 1819), Ophyra aenescens (Wiedemann, 1830), Oxysarcodexia sp., Lepidodexia sp. and Lasiophanes sp.; during the bloating stage C. macellaria, C. albiceps, Lucilia eximia (Wiedemann, 1819), Hemilucillia semidiaphana (Rondani, 1850), Musca domestica Linnaeus, 1758, O. aenescens, Oxysarcodexia sp., Lepidodexia sp., Dermestes maculatus De Geer, 1774 and Lasiphanes sp.; during the active decay C. macellaria, C. albiceps, L. eximia, M. domestica, O. aenescens, Lepidodexia sp. D. maculatus and Lasiophanes sp.; during the advanced decay C. macellaria, C. albiceps, M. domestica, Lepidodexia sp. and Lasiophanes sp.; and during the remains stage C. albiceps, D. maculatus and Lasiophanes sp. The insects were sorted out in 3 ecological categories; necrophagous, predators and parasites and sarco-saprophagous. According to Chao and Jack estimators, total richness was observed on day 20, with 100% of the expected species.
