Economic Impact of Closures on Displaced Workers, May 2002

Iowa Workforce Development research conducted in 2001 on Iowa workers displaced by layoffs indicated that post-layoff wages remained at or above pre-layoff levels. During the layoff quarters selected for analysis – first, second, and third quarters of 1998 – there were twenty-one layoff events, none of which were closures. The research at that time did not discriminate between closures or permanent layoffs for which no recall was expected and those layoff events expected to recall workers. The post/pre ratios1 of the affected workers in manufacturing were at or above 100%, while remaining slightly below the universe pre/post ratios for the same time period.

Iowa's Adult Basic Education Program Annual Benchmark Report Executive Summary, 2002

The purpose of this publication is to present the Executive Summary for the Program Year 2002 report on Iowa’s adult basic education program benchmarks. The passage of the Workforce Investment Act (WIA) of 1998 [Public Law 105-220] by the 105th Congress has ushered in a new era of collaboration, coordination, cooperation and accountability. The overall goal of the Act is “to increase the employment, retention, and earnings of participants, and increase occupational skill attainment by participants, and, as a result improve the quality of the workforce, reduce welfare dependency, and enhance the productivity and competitiveness of the Nation.”

Sistemática, filogenia e distribuição geográfica das espécies sul-americanas de Centris (Paracentris) Cameron, 1903 e de Centris (Penthemisia) Moure, 1950, incluindo uma análise filogenética do "grupo Centris" sensu Ayala, 1998 (Hymenoptera, Apoidea, Centridini)

Systematics, phylogeny and geographical distribution of the South American species of Centris (Paracentris) Cameron, 1903, and Centris (Penthemisia) Moure, 1950, including a phylogenetic analysis of the "Centris group" sensu Ayala, 1998 (Hymenoptera, Apoidea, Centridini). A cladistic analysis with the objective of testing the hypothesis of monophily of Centris (Paracentris) Cameron, 1903, and of studying its phylogenetic relationships with the other subgenera that belong to the Centris group, sensu Ayala, 1998, and the relationships among the species that occur in South America, is presented. Centris (Paracentris) is a group of New World bees of amphitropical distribution, especially diversified in the Andes and in the xeric areas of South and North America. Thirty-one species were included in the analysis, four considered as outgroup, and 49 characters, all from external morphology and genitalia of adult specimens. Parsimony analyses with equal weights for the characters and successive weighting were performed with the programs NONA and PAUP, and analyses of implied weighting with the program PeeWee. The strict consensus among the trees obtained in all the analyses indicates that C. (Paracentris), as previously recognized, is a paraphyletic group. In order to eliminate that condition, the subgenera C. (Acritocentris), C. (Exallocentris) and C. (Xerocentris), all described by SNELLING (1974) are synonymized under C. (Paracentris). The subgenus C. (Penthemisia) Moure, 1950, previously considered a synonym of C. (Paracentris), is reinstated, but in a more restricted sense than originally proposed and with the following species: Centris brethesi Schrottky, 1902; C. buchholzi Herbst, 1918; C. chilensis (Spinola, 1851), C. mixta mixta Friese, 1904, and C. mixta tamarugalis Toro & Chiappa, 1989. Centris mixta, previously recognized as the only South American species of the subgenus C. (Xerocentris), a group supposedly amphitropical, came out as the sister-species of C. buchholzi. The following South American species were recognized under Centris (Paracentris): Centris burgdorfi Friese, 1901; C. caelebs Friese, 1900; C. cordillerana Roig-Alsina, 2000; C. euphenax Cockerell, 1913; C. flavohirta Friese, 1900; C. garleppi (Schrottky, 1913); C. klugii Friese, 1900; C. lyngbyei Jensen-Haarup, 1908; C. mourei Roig-Alsina, 2000; C. neffi Moure, 2000; C. nigerrima (Spinola, 1851); C. toroi sp. nov.; C. tricolor Friese, 1900; C. unifasciata (Schrottky, 1913), and C. vogeli Roig-Alsina, 2000. The relationships among the subgenera of the "Centris group" were: (Xanthemisia (Penthemisia (Centris s. str. - Paracentris))). Centris xanthomelaena Moure & Castro 2001, an endemic species of the Caatinga and previously considered a C. (Paracentris), came out as the sister group of C. (Centris) s. str. A new species of C. (Paracentris) from Chile is described: Centris toroi sp. nov. Lectotypus designations and redescriptions are presented for Centris burgdorfi, C. caelebs, C. lyngbyei, C. tricolor, C. autrani Vachal, 1904 and C. smithii Friese, 1900. New synonyms proposed: C. buchholzi Herbst, 1918 = Centris wilmattae Cockerell, 1926 syn. nov.; C. caelebs Friese, 1900 = Paracentris fulvohirta Cameron, 1903. The female of C. vogeli Roig-Alsina, 2000 and the male of C. xanthomelaena are described.

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.

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.

Impacto de la variación oceanográfica estacional e interanual sobre los ensambles de microfitoplancton, mesozooplancton, ictioplancton y macrozoobentos de dos áreas costeras del norte del Perú entre 1994 y 2002

Se ha analizado la variación oceanográfica y las respuestas de los ensambles de microfitoplancton, mesozooplancton, ictioplancton y macrobentos en las áreas costeras (<20 mn) frente a Paita (05°S) y a San José (06°45’S) durante el período 1994 a 2002. La variación oceanográfica presentó componentes a varias escalas temporales, moduladas por el ciclo ENOS, la propagación de ondas atrapadas hacia la costa y la intensificación estacional del afloramiento costero. La sucesión de los eventos El Niño (EN) 1997-98 y La Niña (LN) 1998-99 presentó características bien diferenciadas en las condiciones físicas superficiales y en la estructura vertical de la columna de agua. El evento EN 1997-98 fue antecedido por el impacto de una onda Kelvin en febrero de 1997, provocando anomalías positivas de temperatura, profundización de la estructura vertical y presencia de algunos indicadores de masas de agua cálida en el plancton, entre febrero y abril de 1997. Estas condiciones se mantuvieron, o se acentuaron, hasta el final del evento. El evento LN 1998-99 se caracterizó por la ausencia de masas de agua cálidas cerca de la costa y la dominancia de aguas costeras frías, la no propagación de ondas Kelvin, la posición somera de aguas frías y pobres en oxígeno, así como la hegemonía de indicadores planctónicos de aguas costeras frías. Estacionalmente, durante otoño-invierno tendieron a desarrollarse condiciones subsuperficiales más oxigenadas (una oxiclina más profunda), mientras que durante el verano las condiciones tendieron a ser menos oxigenadas (hipóxicas, con una oxiclina más somera). Tal patrón no responde a la estacionalidad del afloramiento costero y más bien coincide con la dinámica esperada de la Extensión Sur de la Corriente de Cromwell (ESCC). En general, se determinó un muy buen ajuste de los rangos de tolerancia de algunos organismos planctónicos a las características de las masas de agua dominantes en la capa superficial: Aguas Costeras Frías (ACF), Aguas Ecuatoriales Superficiales (AES) y Aguas Subtropicales Superficiales (ASS), validando la utilidad de estas especies como eficaces indicadores biológicos de masas de agua. Se determinaron los rangos de tolerancia en temperatura y salinidad de los dinoflagelados Protoperidinium obtusum (ACF), Ceratium breve (AES) y Ceratium praelongum (ASS), así como de los copépodos Centropages brachiatus (ACF), Eucalanus inermis (ACF), Centropages furcatus (AES) y Mecynocera clausi (ASS), entre otras. Los indicadores presentaron variaciones en su distribución a lo largo del período estudiado. Los indicadores de ACF fueron detectados durante la mayor parte del estudio, pero ocurrieron hechos sobresalientes durante EN 1997-98: (a) entre los dinoflagelados, Goniodoma polyedricum alcanzó su mayor frecuencia en San José y Pyrocystis lunula frente a Paita; (b) el copépodo Centropages furcatus (AES) incrementó su abundancia frente a Paita y fue hallado frente a San José; (c) se evidenciaron cambios en la composición específica del plancton, detectándose el ingreso de especies no residentes y aumento de la riqueza de especies; (d) las biomasas fitoplanctónica y zooplanctónica tendieron a mostrar una relación directa bajo condiciones neutras del ENOS; sin embargo, al ocurrir variaciones ambientales (EN y LN) presentaron una tendencia contraria; (e) las comunidades del macrobentos en estas dos áreas, mostraron disminuciones significativas en los parámetros comunitarios, contrastando con la respuesta de la macrofauna bentónica frente a la costa central. Este comportamiento frente a Paita pudo obedecer a la alteración del ambiente sedimentario por las muy altas des- cargas del río Chira; y frente a San José, pudo resultar de la disminución local de la producción primaria y del flujo de alimento particulado al bentos. Se sugiere que la disponibilidad de alimento, influenciada por los procesos erosivos sobre el fondo, marca una diferencia clave en la dinámica de estas comunidades en relación a las registradas frente a la costa central, ya que estas últimas habitan en áreas donde pre- dominan los procesos deposicionales y la acumulación de materia orgánica en los sedimentos. Los anfípodos gamáridos, especialmente de la familia Ampeliscidae, mostraron ser más sensibles a los cambios ambientales en el fondo (interfase sedimento-agua) al disminuir significativamente sus poblaciones, en ambas áreas costeras.

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.

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.

Erosividade das chuvas e sua distribuição entre 1989 e 1998 no município de Lages (SC)

A erosão hídrica resulta da erosividade das chuvas e da erodibilidade dos solos. O conhecimento da erosividade, portanto, torna-se um guia valioso na recomendação de práticas de manejo e conservação do solo que visem à redução da erosão hídrica. O objetivo do trabalho foi identificar e quantificar o fator de erosividade das chuvas naturais de Lages (SC), bem como conhecer sua distribuição temporal. A pesquisa foi realizada em 2000, utilizando dados de chuvas e perdas de solo do período entre 1989 e 1998, no Centro de Ciências Agroveterinárias de Lages (SC), situado a 27º 49' de latitude Sul e 50º 20' de longitude Oeste, a 937 m de altitude média, na região do Planalto Sul Catarinense. Foram estudados diversos fatores de erosividade, utilizando os métodos de Wischmeier & Smith e de Wagner & Massambani, de 437 chuvas erosivas, num total de 966 chuvas, compreendendo um volume médio anual de 1.301 mm de chuvas erosivas, num total médio anual de 1.549 mm de chuvas. O EI30 é o fator de erosividade (fator R da Equação Universal de Perda de Solo - EUPS) recomendado para Lages, cujo valor médio anual é de 5.790 MJ mm ha-1 h-1; 63 % do qual ocorre na primavera-verão; 76 % no período de setembro a março e, no período crítico, outubro, janeiro e fevereiro, 41 % do referido fator. Considerando o número e o volume das chuvas, 45 e 84 %, respectivamente, são erosivas.

Erodibilidade de um cambissolo húmico alumínico léptico, determinada sob chuva natural entre 1989 e 1998 em Lages (SC)

O fator de erodibilidade do solo (fator K) da Equação Universal de Perda de Solo (EUPS) refere-se à susceptibilidade natural do solo à erosão e representa a quantidade de solo perdida por unidade de erosividade da chuva (fator R), sendo o seu conhecimento importante no planejamento conservacionista. Utilizando dados de perda de solo, obtidos sob condições de chuva natural, em tanques coletores de escoamento superficial, e de erosividade (EI30) das chuvas naturais, no período de 1989 a 1998, em Lages (SC), calculou-se, pelo quociente entre essas variáveis e por regressão linear simples entre elas, o fator de erodibilidade do solo para um Cambissolo Húmico alumínico léptico com 0,102 m m-1 de declividade média. Com este objetivo, foram utilizados valores de erosividade (EI30) de 437 eventos de chuva e de perdas de solo, obtidas em parcelas de 3,5 x 22,1 m desprovidas de vegetação e crosta superficial. O preparo do solo, executado no sentido paralelo ao declive duas vezes ao ano, consistiu de uma aração e duas gradagens. Os valores de erodibilidade médios anuais, estimados pelo quociente e por regressão linear simples entre as perdas de solo e as erosividades, foram de 0,0115 e 0,0151 Mg ha h ha-1 MJ-1 mm-1, respectivamente. Pelos respectivos modos de obtenção, os valores de erodibilidade médios estacionais estimados foram de 0,0105 e 0,0121 Mg ha h ha-1 MJ-1 mm-1, para a primavera-verão, e de 0,0132 e 0,0220 Mg ha h ha-1 MJ-1 mm-1, para o outono-inverno.

Mathematics in Catalonia: 1996-2002

The aim of this article is to present the main conclusions of the Report on research in Catalonia for the area of mathematics**. The report was prepared by Joaquim Bruna, Marta Sanz, Joan de Solà-Morales and the author of this text, and published by the Institute for Catalan Studies in 1998. In the report, scientific activity in the area of mathematics was measured essentially by examining two parameters: papers published in specialised journals and doctoral theses read. It should be recognised that a considerable amount of activity in the field of mathematics consists of applying existing knowledge to the resolution of practical technological problems that arise in particular companies. This kind of scientific activity was not measured in any way in the report due to the difficulty of obtaining objective data. This article is divided into the following sections: human resources, scientific production, funding, research publications, research centres, and conclusions.

Nation-wide survey on radiation doses in diagnostic and interventional radiology in Switzerland in 1998.

A nation-wide survey on radiation doses in diagnostic and interventional radiology was conducted in Switzerland in 1998 aiming at establishing their collective radiological impact on the Swiss population. The study consisted on the one hand of surveying the frequency of more than 250 types of examinations, covering conventional radiology, mammography, fluoroscopy, angiography, interventional radiology, CT, bone densitometry, conventional tomography and dental radiology. On the other hand, for each type of examination the associated patient dose was established by modeling. The results of this study show that about 9.5 million diagnostic and interventional examinations are performed annually in Switzerland (1.34 per caput) and that the associated annual collective dose is of the order of 7100 person.Sv (1.0 mSv per caput). Switzerland is similar to other European countries in terms of the frequency of examinations and the collective dose.

La jurisdicción competente en materia de responsabilidad patrimonial de la Administración: una polémica que no cesa. Comentario a los Autos de la Sala Especial de Conflictos de Competencia del Tribunal Supremo de 27 de diciembre de 2001 y 21 de octubre de 2002 y propuesta de reforma legislativa

En el presente trabajo se comenta la línea jurisprudencial iniciada por el Auto de la Sala Especial de Conflictos de Competencia del Tribunal Supremo de 27 de diciembre de 2001, por la que se atribuye al orden civil la competencia para enjuiciar las demandas dirigidas conjuntamente contra la Administraciónpública y su aseguradora de responsabilidad extracontractual, reabriendo la polémica que parecía zanjada tras la triple reforma legislativa de 1998 y 1999, que afirmó la competencia exclusiva de la jurisdicción contencioso-administrativa para conocer de los pleitos de responsabilidad patrimonial de la Administración.
