Comparative Survey (comparative + survey)
Selected AbstractsApproaches for Quantifying the Metabolism of Physical Economies: A Comparative Survey: Part II: Review of Individual ApproachesJOURNAL OF INDUSTRIAL ECOLOGY, Issue 1 2002Peter L. Daniels Summary This article is the second of a two-part series that describes and compares the essential features of nine "physical economy" approaches for mapping and quantifying the material demands of the human economy upon the natural environ-ment. These approaches are critical tools in the design and implementation of industrial ecology strategies for greater eco-efficiency and reduced environmental impacts of human economic activity. Part I of the series provided an overview, meth-odological classification, and comparison of a selected set of major materials flow analysis (MFA) and related techniques. This sequel includes a convenient reference and overview of the major metabolism measurement approaches in the form of a more detailed summary of the key specific analytical and other features of the approaches introduced in part I. The surveyed physical economy related environmental analysis ap-proaches include total material requirement and output mod-els, bulk MFA (IFF (Department of Social Ecology, Institute for Interdiscplinary Studies of Austrian Universities) material flow balance model variant), physical input-output tables, substance flow analysis, ecological footprint analysis, environmental space, material intensity per unit service, life-cycle assessment (LCA), the sustainable process index, and company-level MFA. [source] Disclaiming onerous property in insolvency: A comparative studyINTERNATIONAL INSOLVENCY REVIEW, Issue 1 2010Paul J. Omar Insolvency practitioners in charge of certain insolvency procedures have a facility open to them to disclaim property deemed to be onerous and whose retention as part of the debtor's estate may affect the mass of creditors. This article takes a comparative survey of a number of jurisdictions in the common-law and civil-law worlds. Its purpose is to assess whether work carried out at international level seeking to benchmark insolvency procedures generally should be revised to take into account enviornmental concerns in relation to such disclaimed property.

Huang mmedsci Aim:, To compare the sexual expression and sexual satisfaction of women in the UK and Taiwan before and after childbirth, to determine if there is an association between self reported sexual satisfaction and postnatal depression (PND) and the main sources of sexual information for women during this period. Method:, A comparative survey of postnatal women in the UK and Taiwan using a selfadministered questionnaire, a semi structured interview and the Edinburgh Postnatal Depression Scale (EPDS) to investigate sexual satisfaction, sexual expression and main sources of information as well the prevalence of postnatal depression. Results:, Seventy per cent of the UK women and 89% of the Taiwanese women were generally satisfied with their sex life during the postnatal period although in both countries women thought that sexual expression was not as important to themselves as to their partner. There were differences in ranking criteria for physical and emotional sexual satisfaction in the two countries. Eighty-three per cent of UK women had sufficient information about sex during the postnatal period compared to 60% of Taiwanese women. There was no significant difference in the prevalence of PND (18% UK, 19% Taiwan p < 0.01 ANOVA) but significant negative associations (correlation coefficient) between ,sexual self-confidence' and PND in the UK (p < 0.01) and Taiwan (p < 0.05). UK Women with an unsatisfactory sex life (p < 0.05), insufficient sexual information (p < 0.05) and sexual worries after birth (p < 0.05) were more likely to have symptoms of PND. There was a strong association between a poor relationship with her partner and PND (p < 0.001). Conclusions:, These associations may be either a consequence of or a contributing factor to PND. The observed differences between the two countries may be attributed to cross cultural factors and differences in health care systems although further investigation is required. [source] The peristomatic structures of Lithobiomorpha (Myriapoda, Chilopoda): Comparative morphology and phylogenetic significanceJOURNAL OF MORPHOLOGY, Issue 2 2008Markus Koch Abstract A comparative survey of the epipharynx and hypopharynx of lithobiomorph centipedes by light and scanning electron microscopy examines 18 species that sample the major groups of both families, the Lithobiidae and Henicopidae. Cladistic analysis of 11 characters of the peristomatic structures together with 29 additional morphological characters serves as a basis for interpreting the evolution of the lithobiomorph peristomatic structures. Scutigeromorpha is used for outgroup comparison in the framework of a homology scheme for the basic components of the epi- and hypopharynx. Compared to other chilopods, the monophyly of Lithobiomorpha is supported by a row of distinctive bottle-shaped gland openings at the border between the labral and clypeal parts of the epipharynx, as well as by a distinctive shape of the hypopharynx. Paired rows of elongate spines on the clypeal part of the epipharynx are an apomorphic character of Lithobiidae. The transformation of these spine rows into a few groups of branching spines is characteristic for the Monotarsobius group sensu Verhoeff. Similar groups of branching clypeal spines characterize the Anopsobiinae within Henicopidae, whereas Henicopinae possess a dense cluster of short, simple spines instead. The recently described genus Dzhungaria is resolved closer to Henicopinae than to Anopsobiinae, a hypothesis supported by a field of grooves on the medial labral part of the epipharynx. Monophyly of Henicopidae does not receive unique support from the peristomatic structures although two homoplastic characters contribute to this node; among these, the reduction of a median spine field between clypeal and labral parts of the epipharynx to a narrow transverse band also supports a close relationship between the Ezembius group and Hessebius within Lithobiidae. An Ezembius + Hessebius clade is additionally supported by the absence of a transverse bulge between the clypeal and labral parts of the epipharynx, a character otherwise present in all lithobiomorph species studied so far. Lithobius is resolved as polyphyletic, with different species being most closely related to such genera as Australobius, Hessebius and Pleurolithobius. J. Morphol., 2008. © 2007 Wiley-Liss, Inc.

Schmidt Data concerning the cytoskeletal components of red algae are scant. The goal of this ongoing comparative survey is to develop a more complete characterization of the red algal cytoskeleton, and subsequent elucidation of its function, using representative taxa belonging to major evolutionary lineages within the Rhodophyta. Preliminary data were obtained using enzyme digestion of cell walls and detergent rinses with direct (phalloidin) and indirect (monoclonal antibodies) labeling methods for microfilaments and tubulin, respectively. Samples were viewed using confocal laser scanning microscopy. Results will be discussed in light of the more thoroughly understood cytoskeletal system reported for green algae. [source] Gene expression profiling of Dunaliella sp. acclimated to different salinitiesPHYCOLOGICAL RESEARCH, Issue 1 2010Minjung Kim SUMMARY To investigate which genes may be important for growth under extreme conditions such as very low or high salinities, a survey of the Dunaliella sp. transcriptome was performed with a cDNA microarray which had been generated previously representing 778 expressed sequence tags. The comparative microarray analysis indicated that 142 genes differed in expression levels by more than twofold in cells grown at extreme salinities (0.08 M and 4.5 M NaCl) when compared with cells grown at intermediate salinity (1.5 M NaCl). Of these genes, 28 had increased expression and 57 were suppressed in cells grown at low salinity. In cells grown at high salinity, 43 genes showed increased expression and 69 genes showed suppressed expression. However, we did observe a large overlap in the expression of extreme salinity-responsive genes based on Venn diagram analysis, which found 55 genes that responded to both of the two extreme salinity conditions. Further, we found that several genes had similar expression levels under low and high salinities, including some general stress response genes that were upregulated in both extreme salinity conditions. For confirmation of the validity of the cDNA microarray analysis, expression of several genes was independently confirmed by the use of gene-specific primers and real-time polymerase chain reaction. The present study is the first large-scale comparative survey of the transcriptome from the microalga Dunaliella sp. acclimated to extreme salinities, thus providing a platform for further functional investigation of differentially expressed genes in Dunaliella. [source] Spatial distribution of the Japanese common squid, Todarodes pacificus, during its northward migration in the western North Pacific OceanFISHERIES OCEANOGRAPHY, Issue 2 2006ATSUSHI KAWABATA Abstract The spatial distribution of Todarodes pacificus in and near the Kuroshio/Oyashio Transition Zone during its northward migration was examined by comparative surveys using two types of mid-water trawl net and supplementary squid jigging from June to July 2000. The vertical and horizontal distribution patterns varied for different body sizes in relation to the oceanographic structure. Todarodes pacificus of 1,20 cm dorsal mantle length (ML) were widely distributed from the coastal waters of Japan to near 162°E longitude, probably due to transport by the Kuroshio Extension (KE). Todarodes pacificus smaller than 10 cm ML were mainly distributed in temperate surface layers at sea surface temperatures (SSTs) >15°C near the KE meander probably because of their poor tolerance to lower temperatures and limited swimming ability. Squid of 10,15 cm ML were distributed in the offshore waters of 10,15°C SST and in the coastal waters of northern Honshu, and underwent diel vertical migrations between the sea surface at night and deeper layers during the daytime. Squid larger than 15 cm ML were distributed in the coastal feeding grounds of northern Honshu and Hokkaido until they began their southward spawning migration. They also underwent diel vertical migrations, but remained deeper at night than the squid of 10,15 cm ML; this migration pattern closely matched that of their main prey such as euphausiids. We concluded that as T. pacificus grow, they shift their distribution range from the temperate surface layer around the KE toward the colder deeper layers, above 5°C, in the Oyashio and coastal areas.
