2008 Iowa Real Property Appraisal Manual, May 2008

********NOTE: There are nine sections to this manual, all in separate files.************* **********NOTE: Large files may take longer to open******** The basis of real property assessment in Iowa is market value as defined in Iowa Code §441.21. Iowa Code §§ 421.17(17) and 441.21(h) provide that assessment jurisdictions follow the guidelines and rules in this manual to help achieve uniformity in assessments. Assessors are encouraged to use the International Association of Assessing Officers’ Standard on Mass Appraisal of Real Property in their mass appraisal practices. Estimating market value in mass appraisal involves accurately listing properties, developing a sales file that includes the primary influences on market value, and developing models for subsets of properties that share common market influences using recognized mass appraisal techniques. The assessment of an individual property should not be based solely on the sale price. The Uniform Standards of Professional Appraisal Practice (USPAP) standard 6 says “In developing a mass appraisal, an appraiser must be aware of, understand, and correctly employ those recognized methods and techniques necessary to produce and communicate credible mass appraisals.” Accurate listing of property is the basis of a good mass appraisal program. On-site inspection and listing of property is essential in developing a good data base for revaluation. A physical review, including an on-site verification of property characteristics, should be conducted at least every four to six years. Land values should be reviewed every two years. Factors influencing the market of each property type should be identified and collected so that these factors can be considered in the mass appraisal model. It is equally important to maintain the data once it is collected. Accessing local government permit systems should be a part of a good data maintenance program along with an inspection program. Current cadastral maps and geographical information systems (GIS) are tools that are integral in checking accuracy of listings and maintaining a comprehensive data base.

Análise Psicológica do Divórcio: Uma perspectiva masculina

O presente trabalho tem como objectivo geral analisar o divórcio numa perspectiva masculina. Quanto ao enfoque metodológico, neste trabalho optamos por compreender o problema através de uma linha de pesquisa qualitativa. Neste estudo participaram oito indivíduos do sexo masculino, de diferentes idades e com tempo como divorciados diferentes, na cidade da Praia, com ou sem filhos. Como técnica de recolha de dados utilizamos a entrevista semi-estruturada, em que as respostas foram registadas e tratadas com base na análise de conteúdo.A análise de dados demonstrou que esses oito homens que passaram pela situação de divórcio, apresentaram sintomas de depressão como por exemplo, a tristeza, a sensação de vazio, choro, sentimento de solidão e a anedonia, porém nenhum dos entrevistados fez uso de substâncias, salvo um deles que abusou um pouco de bebidas alcoólicas mais do que o de costume.

The evolution of helping and harming on graphs: the return of the inclusive fitness effect.

Evolutionary graph theory has been proposed as providing new fundamental rules for the evolution of co-operation and altruism. But how do these results relate to those of inclusive fitness theory? Here, we carry out a retrospective analysis of the models for the evolution of helping on graphs of Ohtsuki et al. [Nature (2006) 441, 502] and Ohtsuki & Nowak [Proc. R. Soc. Lond. Ser. B Biol. Sci (2006) 273, 2249]. We show that it is possible to translate evolutionary graph theory models into classical kin selection models without disturbing at all the mathematics describing the net effect of selection on helping. Model analysis further demonstrates that costly helping evolves on graphs through limited dispersal and overlapping generations. These two factors are well known to promote relatedness between interacting individuals in spatially structured populations. By allowing more than one individual to live at each node of the graph and by allowing interactions to vary with the distance between nodes, our inclusive fitness model allows us to consider a wider range of biological scenarios leading to the evolution of both helping and harming behaviours on graphs.

Tawny Owl Strix aluco as a bioindicator of Barn Owl Tyto alba breeding and the effect of winter severity on Barn Owl reproduction

In the temperate zone, food availability and winter weather place serious constraints on European Barn Owl Tyto alba populations. Using data collected over 22years in a Swiss population, we analysed the influence of early pre-breeding food conditions and winter severity on between-year variations in population size and reproductive performance. To estimate pre-breeding food conditions, we attempted a novel approach based on an index that combines Tawny Owl Strix aluco reproductive parameters and the occurrence of wood mice Apodemus sp. in their diet. Tawny Owls breed earlier in the season than Barn Owls and are strongly dependent on the abundance of wood mice for breeding. This index was strongly positively associated with the number of breeding pairs and early breeding in the Barn Owl. Winter severity, measured by snow cover and low temperatures, had a pronounced negative influence on the size of the breeding population and clutch size. Food conditions early in the breeding season and winter severity differentially affect the Barn Owl life cycle. We were able to use aspects of the ecology and demography of the Tawny Owl as an indicator of the quality of the environment for a related species of similar ecology, in this case the Barn Owl.

Resistência inter e intra-agregados em ensaios de cisalhamento direto de um nitossolo vermelho distrófico

Para solos agregados, a envoltória da resistência ao cisalhamento pode ser dividida em dois segmentos, com declividades e interceptos diferentes. Um primeiro segmento mais inclinado e com intercepto menor representaria a envoltória de ruptura definida pelo atrito e coesão interagregados, enquanto o segundo segmento, menos inclinado e com intercepto maior, seria a envoltória definida pelo atrito e coesão intra-agregados. O presente estudo foi realizado com o objetivo de avaliar se a envoltória de resistência ao cisalhamento de agregados do horizonte superficial de um Nitossolo Vermelho pode ser subdividida em segmentos distintos, com coeficientes angulares diferentes, e se isso está relacionado à existência de agregados nele. Inicialmente, amostras coletadas na superfície de um Nitossolo Vermelho distrófico latossólico de textura argilosa foram submetidas ao ensaio de cisalhamento direto com pressões normais de 24,4; 48,9; 98,2; 196,4; 294,6; 392,8 e 491,8 kPa. Posteriormente, o ensaio foi realizado com amostras de agregados de cinco classes de diâmetro: < 0,25; 0,25-0,50; 0,50-1,00; 1,00-2,00 e 2,00-4,00 mm, empregando-se pressões normais de 24,4; 48,9; 73,5; 147,3; 294,6; 441,9; 589,2 e 736,6 kPa. Em todos os ensaios, verificou-se que as envoltórias obtidas podem ser divididas em dois segmentos de reta. Os resultados indicam que a agregação deve ser considerada na definição das cargas normais a serem utilizadas no ensaio de cisalhamento direto, bem como na análise dos resultados, pois ela tem efeitos sobre a envoltória de resistência ao cisalhamento. Para o Nitossolo Vermelho distrófico usado neste estudo, constatou-se que, na umidade em que as amostras foram ensaiadas, os agregados definem a resistência ao cisalhamento do solo para cargas normais de até 294,6 kPa.

Control of introduced species using Trojan sex chromosomes.

To control introduced exotic species that have predominantly genetic, but environmentally reversible, sex determination (e.g. many species of fish), Gutierrez and Teem recently modeled the use of carriers of Trojan Y chromosomes--individuals who are phenotypically sex reversed from their genotype. Repeated introduction of YY females into wild populations should produce extreme male-biased sex ratios and eventual elimination of XX females, thus leading to population extinction. Analogous dynamics are expected in systems in which sex determination is influenced by one or a few major genes on autosomes.

Soil compaction and eucalyptus growth in response to forwarder traffic intensity and load

During timber exploitation in forest stands harvesting machines pass repeatedly along the same track and can cause soil compaction, which leads to soil erosion and restricted tree root growth. The level of soil compaction depends on the number of passes and weight of the wood load. This paper aimed to evaluate soil compaction and eucalyptus growth as affected by the number of passes and wood load of a forwarder. The study was carried out in Santa Maria de Itabira county, Minas Gerais State - Brazil, on a seven-year-old eucalyptus stand planted on an Oxisol. The trees were felled by chainsaw and manually removed. Plots of 144 m² (four rows 12 m long in a 3 x 2 m spacing) were then marked off for the conduction of two trials. The first tested the traffic intensity of a forwarder which weighed 11,900 kg and carried 12 m³ wood (density of 480 kg m-3) and passed 2, 4, and 8 times along the same track. In the second trial, the forwarder carried loads of 4, 8, and 12 m³ of wood, and the machine was driven four times along the same track. In each plot, the passes affected four rows. Eucalyptus was planted in 30 x 30 x 30 cm holes on the compacted tracks. The soil in the area is clayey (470 clay and 440 g kg-1 sand content) and at depths of 0-5 cm and 5-10 cm, respectively, soil organic carbon was 406 and 272 g kg-1 and the moisture content during the trial 248 and 249 g kg-1. These layers were assessed for soil bulk density and water-stable aggregates. The infiltration rate was measured by a cylinder infiltrometer. After 441 days the measurements were repeated, with additional analyses of: soil organic carbon, total nitrogen, N-NH4+, N-NO3-, porosity, and penetration resistance. Tree height, stem diameter, and stem dry matter were measured. Forwarder traffic increased soil compaction, resistance to penetration and microporosity while it reduced the geometric mean diameter, total porosity, macroporosity and infiltration rate. Stem dry matter yield and tree height were not affected by soil compaction. Two passes of the forwarder were enough to cause the disturbances at the highest levels. The compaction effects were still persistent 441 days after forwarder traffic.

Sinergismo Bacillus, Brevibacillus e, ou, Paenibacillus na simbiose Bradyrhizobium-caupi

O feijão-caupi Vigna unguiculata [L.] Walp. é a principal cultura de subsistência do semiárido brasileiro, sendo fonte de proteínas de baixo custo, notadamente, para populações carentes. A produção dessa cultura no Nordeste é baixa devido à não utilização de insumos agrícolas - entre eles, o fertilizante nitrogenado. Por outro lado, bactérias promotoras de crescimento em plantas (BPCPs) vêm sendo estudadas, de forma a maximizar a fixação de N2, disponibilizar nutrientes como P ou fito-hormônios e inibir doenças. Os objetivos deste trabalho foram verificar a viabilidade da coinoculação das sementes de feijão-caupi usando Paenibacillus, Brevibacillus e, ou, Bacillus e Bradyrhizobium-caupi; caracterizar as estirpes quanto à produção de ácido indol acético (AIA) e solubilização de fosfato; e avaliar o sinergismo entre os microrganismos como alternativa para otimizar a FBN. Os experimentos foram conduzidos em laboratório e em casa de vegetação do Instituto Agronômico de Pernambuco (IPA), utilizando o feijão-caupi cv. "IPA - 206". As estirpes utilizadas foram: Bacillus sp. - 449, 450, 451, 461 e ANBE 31; B. cereus - 440; B. subtilis - 438, 441, 454, 455 e 459; B. pumilus - 444, 445 e 448; B. megaterium - 462; Brevibacillus brevis - 447; Paenibacillus brasilensis - 24, 172 e 177; P. graminis - MC 04.21, MC 22.13 e BR 60106; P. polymyxa - S21; e P. durus - RBN4. Os microrganismos não apresentaram capacidade para produzir AIA nem solubilizar fosfato. Ocorreu sinergismo das estirpes de Bacillus sp. (449) e Bacillus pumilus (444) coinoculadas com a estirpe de Bradyrhizobium sp. (BR 3267) no feijão-caupi.

State-of-the-art of 3D cultures (organs-on-a-chip) in safety testing and pathophysiology.

Integrated approaches using different in vitro methods in combination with bioinformatics can (i) increase the success rate and speed of drug development; (ii) improve the accuracy of toxicological risk assessment; and (iii) increase our understanding of disease. Three-dimensional (3D) cell culture models are important building blocks of this strategy which has emerged during the last years. The majority of these models are organotypic, i.e., they aim to reproduce major functions of an organ or organ system. This implies in many cases that more than one cell type forms the 3D structure, and often matrix elements play an important role. This review summarizes the state of the art concerning commonalities of the different models. For instance, the theory of mass transport/metabolite exchange in 3D systems and the special analytical requirements for test endpoints in organotypic cultures are discussed in detail. In the next part, 3D model systems for selected organs--liver, lung, skin, brain--are presented and characterized in dedicated chapters. Also, 3D approaches to the modeling of tumors are presented and discussed. All chapters give a historical background, illustrate the large variety of approaches, and highlight up- and downsides as well as specific requirements. Moreover, they refer to the application in disease modeling, drug discovery and safety assessment. Finally, consensus recommendations indicate a roadmap for the successful implementation of 3D models in routine screening. It is expected that the use of such models will accelerate progress by reducing error rates and wrong predictions from compound testing.
