Effect of Replacing Menhaden Oil with Catfish Oil on the Fatty Acid Composition of Juvenile Channel Catfish, Ictalurus punctatus
Authors: O’Neal Clifford C. , Kohler Christopher C. 
Published: January 2008

Abstract The effect of using a finishing diet containing menhaden fish oil on the fatty acid composition of fingerling channel catfish, Ictalurus punctatus, was evaluated in a 12‐wk growth trial. Three isocaloric, isonitrogenous practical diets with three different sources of lipids (menhaden oil [MO], catfish oil [CO], or beef tallow [BT]) were formulated (35% crude protein). No differences in eicosapentaenoic acid, docosahexaenoic acid, or arachidonic acid were observed to occur in catfish fed MO or CO diets; however, these fatty acids were significantly lower in fish fed BT diet. No differences were observed for unsaturated fatty acid content in channel catfish fed a diet containing MO for 8 or 12 wk. In addition, no differences in production characteristics were observed to occur when catfish were fed diets containing CO, MO, or BT as the dietary lipid source, which indicates that BT, CO, and MO are equally effective as sources of energy. It is apparent from these results that CO may be successfully substituted for MO in formulated diets without adversely affecting n‐3 highly unsaturated fatty acid content in channel catfish.
The Effect of Dietary Lipid and Long‐chain n‐3 PUFA Levels on Growth, Energy Utilization, Carcass Quality, and Immune Function of Rainbow Trout, Oncorhynchus mykiss

Abstract The effect of varying dietary lipid and n‐3 polyunsaturated fatty acids (PUFAs) on growth, feed efficiency, protein and energy utilization, carcass quality, and nonspecific immune functions was investigated in rainbow trout reared at two different water temperatures (7.5 and 15 C). Six diets were formulated to contain 47% digestible protein and 21 MJ/kg digestible energy. Three of the diets were formulated to contain increasing lipid levels (10, 16, and 18%) and three additional diets formulated to 18% lipid with different lipid sources. Varying dietary lipid and n‐3 PUFA levels had little effect on growth and on protein and energy utilization. Diet composition only had limited effect on susceptibility of the flesh to rancidity and on the nonspecific immunity of the fish. Increasing lipid levels did not affect fish carcass or fillet proximate composition. Replacing half of fish oil with beef tallow resulted in lower n‐3 PUFAs in fish fillet but did not affect nutrient digestibility or growth performance of fish even at 7.5 C. Increasing dietary n‐3 levels using a fish oil concentrate resulted in significant enrichment of n‐3 PUFAs and elevated n‐3 : n‐6 ratio of the whole body and carcass. Water temperature significantly affected apparent digestibility coefficient (ADC) of protein and energy but did not affect the ADC of lipid, nor did it affect nitrogen and energy retention efficiencies. The study suggests that highly saturated fats, such as beef tallow, can be used to partially replace fish oil without negative effect on digestibility and growth even at low water temperature. High dietary n‐3 PUFAs levels can be used to enrich n‐3 PUFAs of the flesh without negative effect on the immune response.
Rebuilding Australia's Linguistic Profile: Recent Developments in Research on Australian Aboriginal Languages
Authors: Gaby Alice 
Published: January 2008

AbstractThe more than 250 languages spoken in Australia prior to the nineteenth century exhibit both striking similarities to one another and remarkable variation. The exponential increase in what linguists have learned about these languages since the 1960s has been sadly in inverse proportion to the number of people learning them as a mother tongue. This article will review some of the most exciting recent developments in Australianist linguistic research, while also acknowledging the context of language loss and disenfranchisement within which they are situated. The message it offers is ultimately optimistic, however. For the languages still spoken regularly, research into the previously neglected components of the multimodal communicative system that is language in use is adding new depth to the existing documentation. For the majority of Australia's indigenous languages – where economic, social and political pressures have taken their toll – a different set of concerns has emerged. Linguists are now grappling with a range of theoretical and empirical questions regarding the mechanisms of language contact and attrition, even as they continue to contribute new insights into the traditional ‘core’ fields of phonetics and phonology, morphosyntax, semantics and historical linguistics. Moreover, an increasing consciousness of the respective roles of outsider researcher and speech community is changing not only the methodologies of linguists ‘in the field’, but also the research itself. All of these factors will shape the directions of future Australianist linguistic research, as well as the number and nature of languages that remain to be studied.

AbstractLewy‐related pathology (LRP) is a common pathologic finding at autopsy in dementia patients. Recently criteria for categorizing types of LRP in dementia patients were published, though these criteria have yet to be systematically applied to large dementia samples. We examined a large (n = 208) referral‐based autopsy sample for LRP, and applied the published criteria for LRP categorization to these cases. We found almost half (49%) of LRP positive cases from this sample were not classifiable. However, modifying the published criteria by reducing the number of regions requiring examination, allowing more variability in LRP severity scores within specific brain regions, and adding an amygdala predominant category permitted classification of 97% of LRP positive cases from the referral‐based sample. Application of the modified criteria to an unrelated community‐based autopsy sample (n = 226) allowed classification of 96% of LRP positive cases. Modest modifications in the published criteria permit a significantly greater number of dementia cases with LRP to be classified. In addition, this modification allows for more limited sampling of brain regions for classification of LRP. We propose that these modified criteria for the categorization of LRP be utilized in patients with a history of dementia.

Published: January 2008

AbstractMucosal infections caused by the pathogenic fungus Candida are a significant infectious disease problem and are often difficult to eradicate because of the high frequency of resistance to conventional antifungal agents. Photodynamic treatment (PDT) offers an attractive therapeutic alternative. Previous studies demonstrated that filamentous forms and biofilms of Candida albicans were sensitive to PDT using Photofrin as a photosensitizer. However, early stationary phase yeast forms of C. albicans and Candida glabrata were not adversely affected by treatment. We report that the cationic porphyrin photosensitizer meso‐tetra (N‐methyl‐4‐pyridyl) porphine tetra tosylate (TMP‐1363) is effective in PDT against yeast forms of C. albicans and C. glabrata. Respiratory‐deficient (RD) strains of C. albicans and C. glabrata display a pleiotropic resistance pattern, including resistance to members of the azole family of antifungals, the salivary antimicrobial peptides histatins and other types of toxic stresses. In contrast to this pattern, RD mutants of both C. albicans and C. glabrata were significantly more sensitive to PDT compared to parental strains. These data suggest that intact mitochondrial function may provide a basal level of anti‐oxidant defense against PDT‐induced phototoxicity in Candida, and reveals pathways of resistance to oxidative stress that can potentially be targeted to increase the efficacy of PDT against this pathogenic fungus.
Different Molecular Constituents in Pheomelanin are Responsible for Emission, Transient Absorption and Oxygen Photoconsumption†

Published: January 2008

AbstractSteady‐state absorption and emission spectroscopies, oxygen activation and transient spectroscopy on a single sample of synthetic pheomelanin are compared. The absorption, emission and excitation spectra of pheomelanin depend on the molecular weight (MW) of the dissolved pigment constituents. While weakly‐depending on MW, the maximum of the emission excitation spectrum is ∼400 nm. The electron paramagnetic resonance oximetry measurements show a clear increase in oxygen uptake between 338 and 323 nm, and also reveal a local enhancement around ∼370 nm. Pump‐probe absorption spectroscopy reveals that photoexcitation of pheomelanin by UVA light generates a transient absorption peak in the visible and UV regions within the instrument response. The action spectrum for the formation of the 780 nm transient species peaks at ∼360 nm. While both transient absorption bands show the same ultrafast decay component, the 780 nm peak completely vanishes on the 10s of picosecond time scale, but the UV band shows a kinetic evolution to a subsequent intermediate. While in a similar wavelength range, the maximum of the action spectrum derived from the transient data, the emission excitation spectrum and the action spectrum for photoconsumption all differ from one another, suggesting that the chromophore responsible for each is not that same. This raises concern about comparing the results from different photochemical methodologies for melanin, which is a specific case of comparing data on systems where molecular constituents are not well defined.
Sensitivity of UV Erythemally Effective Irradiance and Daily Dose to Spatial Variability in Total Ozone

Published: January 2008

AbstractThe total ozone column (TOC) is the most significant quantity for estimating the erythemally effective UV radiation under clear sky conditions. Uncertainties in TOC measurements and a limited spatial and temporal resolution therefore influence the quality of calculated erythemally effective radiation. The UV Index, the internationally accepted measure of the erythemally effective radiation, is used in public and the media to inform about current levels of UV radiation and builds the base for sun protection. Thus, the accuracy of the promoted values is essential. While in a preceding study we estimated the influence of measurement uncertainties, in this study we analyze the influence of spatial gaps and variability of TOC to the erythemally effective irradiance at noon and to the daily dose. The results allow defining the necessary spatial resolution of TOC values when a certain accuracy for the UV Index or for the purpose of sun protection is required. In case of the erythemally effective irradiance this study reveals that spatial gaps in TOC or the assumption of spatial invariability causes similar uncertainties independent of the geographic location. At higher latitudes the higher spatial variability of TOC counteracts the lower level of irradiance. For the daily dose gaps in TOC have an even higher impact at higher latitudes.
Variations in Chemical Composition of Clay Minerals and Magnetic Susceptibility of Hydrothermally Altered Rocks in the Hishikari Epithermal Gold Deposit, SW Kyushu, Japan
Authors: Murakami Hiroyasu 
Published: January 2008

AbstractHydrothermal alteration, involving chiefly chlorite and illite, is extensively distributed within host rocks of the Pleistocene Hishikari Lower Andesites (HLA) and the Cretaceous Shimanto Supergroup (SSG) in the underground mining area of the Hishikari epithermal gold deposit, Kagoshima, Japan. Approximately 60% of the mineable auriferous quartz‐adularia veins in the Honko vein system occur in sedimentary rocks of the SSG, whereas all the veins of the Yamada vein system occur in volcanic rocks of the HLA. Variations in the abundance and chemical composition of hydrothermal minerals and magnetic susceptibility of the hydrothermally altered rocks of the HLA and SSG were analyzed. In volcanic rocks of the HLA, hydrothermal minerals such as quartz, chlorite, adularia, illite, and pyrite replaced primary minerals. The amount of hydrothermal minerals in the volcanic rocks including chlorite, adularia, illite, and pyrite as well as the altered and/or replaced pyroxenes and plagioclase phenocrysts increases toward the veins in the Honko vein system. The vein‐centered variation in mineral assemblage is pronounced within up to 25 m from the veins in the peripheral area of the Honko vein system, whereas it is not as apparent in the Yamada vein system. The hydrothermal minerals in sandstone of the SSG occur mainly as seams less than a few millimeters thick and are sporadically observed in halos along the veins and/or the seams. The alteration halos in sandstone of the SSG are restricted to within 1 m of the veins. In the peripheral area of the Honko vein system, chlorite in volcanic rocks is characterized by increasing in Al in its tetrahedral layer and the Fe/Fe + Mg ratio toward the veins, while illite in volcanic rocks has relatively low K and a restricted range of Fe/Fe + Mg ratios. Temperature estimates derived from chlorite geothermometry rise toward the veins within the volcanic rocks. The magnetic susceptibility of tuff breccia of the HLA varies from 21 to less than 0.01 × 10−3 SI within a span of 40 m from the veins and has significant variation relative to that of andesite (27–0.06 × 10−3 SI). The variation peripheral to the Honko vein system correlates with an increase in the abundance of hematite pseudomorphs after magnetite, the percentage of adularia and chlorite with high Fe/Fe + Mg ratios, and the degree of plagioclase alteration with decreasing distance to the veins. In contrast, sedimentary rocks of the SSG maintain a consistent magnetic susceptibility across the alteration zone, within a narrow range from 0.3 to 0.2 × 10−3 SI. Magnetic susceptibility of volcanic rocks of the HLA, especially tuff breccia, could serve as an effective exploration tool for identifying altered volcanic rocks.
Gold Abundance and Stable Isotopes (H, O, S) in Hydrothermal Alteration Zones of Gasa Island (Gasado), Korea
Authors: Yoon Chung‐Han , Jung Hyoung‐Su 
Published: January 2008

AbstractGeology of the Gasa Island (Gasado), Korea, consists mainly of tuffaceous rocks, rhyolite and andesitic rocks related to Cretaceous volcanic activity. These rocks are hydrothermally altered, and are classified into the following four alteration zones based on the alteration mineral assemblages: advanced argillic alteration (alunite‐pyrophyllite‐kaolinite‐pyrite); sericitic alteration (sericite‐kaolinite‐quartz); propylitic alteration (quartz‐chlorite‐carbonate‐pyrite); and silicified zones. Alunite in the advanced argillic zone occurred in two types; a massive or disseminated type and a vein type. Most of the massive or disseminated alunites are ≥50 μm in size, whereas the size of vein alunites is <20–30 μm. Alunite grain size is greater in the central part of disseminated or massive alunite, while it is smaller toward the margins. The gold content of each alteration zone is 21–2900 ppb, 15–88 ppb, 57–1730 ppb, and 2–231 ppb, respectively. The gold content of quartz veins developed in the alteration zones is 39–715 ppb. Gold is enriched in the minerals and rocks around faults and fissures, and is strongly concentrated in the advanced argillic alteration zone around faults. Hydrothermal solutions traveling along the fracture systems might be responsible for the comparatively high gold content in the study area. δ34S of alunites occurring in the advanced argillic alteration zone range from +16.5 to +3.9‰, although most are in a comparatively narrow range from +8.6 to +5.2‰. There is no difference between disseminated or massive and vein alunites. The δ34S of pyrites in the advanced argillic alteration zone are from +4.8 to −2.9‰. Oxygen and hydrogen isotope values of alunites are from +8.5 to 0‰ and from −59.6 to −97.3‰, respectively. With an assumed temperature of 200°C, δD and δ18O of hydrothermal solutions calculated for alunites are from −53.6 to −91.3‰, and from −2.4 to −8.1 for massive or disseminated alunites and from −6.6 to −10.9‰ for vein alunites, respectively. These data suggest that meteoric water dominated during the alunite formation. Isotopic data, geological setting, mineralogy, size of alunite and pure alunite composition (K end member) indicate that alunites of the study area were formed in the steam‐heated environment of acid sulfate alteration.
Exploring Causes of the Self‐serving Bias
Authors: Shepperd James , Malone Wendi , Sweeny Kate 
Published: January 2008

AbstractThe self‐serving bias refers to a tendency for people to take personal responsibility for their desirable outcomes yet externalize responsibility for their undesirable outcomes. We review a variety of explanations for this attribution bias. Although researchers have historically pitted cognitive and motivational explanations for the self‐serving bias against one another, cognitive and motivation processes often work in tandem to lead people to conclude that they are responsible for the desirable but not the undesirable outcomes.
Culture, Gender, and Men's Intimate Partner Violence
Authors: Vandello Joseph A. , Cohen Dov 
Published: January 2008

AbstractThis article reviews research on cultural beliefs and expectations about gender and romantic relationships that are related to male intimate partner violence. We link beliefs about men (manhood is tenuous and must be proven, men must protect women, and honor must be defended), about women (good women put sacrifice and family loyalty first and good women are morally and sexually pure), and about relationships (jealousy is a sign of passionate love) to show how they create a cultural context in which intimate partner violence is tolerated, accepted, or rejected. We end by discussing avenues for future research that take an expansive approach to examining culture's influence on intimate violence.
Outlines of a Critical Sociology of Consumption: Beyond Moralism and Celebration
Authors: Rief Silvia 
Published: January 2008

AbstractThe ‘new’ sociology of consumption that emerged in the 1980s acknowledged that consumption is a significant cultural and social practice and not just a mere signifier of the pathological elements of contemporary societies. Arguably, this rehabilitation of consumption has overshot its mark and has led to an overly positive, complacent and celebratory rendering of consumption and to an overriding concern with the symbolic and communicative dimension of goods. Driven by the debates on globalization, political consumerism and the relation between consumption and citizenship, current work shows increased interest in the politics of consumption. The article explores in what directions the classic concern with the symbolic and communicative dimension of goods might be taken if it is more thoroughly grounded in an analysis of the politics of consumption and of the current reconfigurations of consumers and citizens. The overall aim is to outline a basis for a critical sociology of consumption.
The Sociological Significance of Sleep: Progress, Problems and Prospects
Authors: Williams Simon J. 
Published: January 2008

AbstractSleep is something we all ‘do’ on a daily or nightly basis, consuming approximately a third of our lives. It is only relatively recently, however, that sociologists have begun to address the social significance of sleep. This paper, therefore, provides an invitation of sorts to a rich and fascinating new field of sociological inquiry, charting and commentating on the sociological significance of sleep in relation to the following seven key themes: (i) body and society; (ii) roles and routines; (iii) history and culture; (iv) work and employment; (v) gender and the life course; (vi) health and illness; and finally, (vii) politics and ethics. The paper concludes with some further critical thoughts and reflections on this sociological engagement with sleep to date and the theoretical, conceptual and methodological challenges ahead.
Where within a geographical range do species survive best? A matter of scale
Authors: THOMAS CHRIS D. , BULMAN CAROLINE R. , WILSON ROBERT J. 
Published: January 2008

Abstract. Opinions differ as to whether declining species are most likely to survive in central or peripheral parts of their distributions. The former pattern is likely to be driven by high extinction risks in peripheral areas; the latter by gradients of extinction risk.At a continental scale of analysis, the declining butterflyEuphydryas auriniasurvived best in southern and eastern countries within Europe. This was statistically associated with geographical variation in agricultural intensification. At this scale of analysis, there was a gradient of survival, caused by a gradient of agricultural intensification.Within England and Wales, survival was greatest in population concentrations, or core areas; that is in 10‐km grid squares that were surrounded by other 10‐km grid squares that also contained populations ofE. aurinia.In the English county of Dorset, populations were also most likely to be found in core areas; that is in habitat patches that were close to other populated habitat patches.In this system, there is support for two patterns of decline. At a coarse scale, there is a geographical gradient of habitat degradation, associated with agricultural intensification. But within a region where decline has taken place, populations survive best in core areas, where aggregations of habitat support viable metapopulation dynamics.Large‐scale geographical patterns of decline towards the periphery (or other locations within) the distribution of a species do not negate the validity of conservation strategies based on core‐margin population dynamic principles. Core areaswithineach country or region represent appropriate targets for conservation action.
