Reconciling self: gay men and lesbians using domestic materiality for identity management

Responding to calls to ‘re-materialize’ research in social and cultural geography, this paper critically considers the role of domestic materiality in gay/lesbian identity management, and makes a particular contribution to work on gay men's and lesbians' experiences, meanings and uses of domestic environments. Prior work in other contexts has shown that the maintenance of domestic materiality—that is, the accumulation and arrangement of meaningful possessions in domestic space—underwrites identity work. Drawing on in-depth interviews with gay/lesbian Australians, I apply this contention to gay/lesbian homemaking practices. In particular, conceptualizing identity as fractured, I argue that the maintenance of domestic materiality reconciles diverse dimensions of multi-faceted selves. Different possessions embody different facets of self—not only sexuality, but also familial connections, cultural heritage, spiritual beliefs, inter alia. Juxtaposing these objects at home brings together the diverse fragments of self, materially embedding a holistic sense of self within domestic space. Domestic materiality thus (re)unites various dimensions of fractured selves, reconciling sexual identities with familial, ethnic-cultural and spiritual identities, inter alia. This reconciliatory function of material homemaking is a key way in which sexual identities are affirmed in the everyday lives of these gay/lesbian Australians.
Experimental investigation of chemical-looping combustion and chemical-looping gasification of biomass-based fuels using steel converter slag as oxygen carrier

Chemical-looping combustion (CLC) is a combustion process with inherent separation of CO2, which is achieved by oxidizing the fuel with a solid oxygen carrier rather than with air. As fuel and combustion air are never mixed, no gas separation is necessary and, consequently, there is no direct energy penalty for the separation of gases. The most common form of design of chemical-looping combustion systems uses circulating fluidized beds, which is an established and widely spread technology. Experiments were conducted in two different laboratory-scale CLC reactors with continuous fuel feeding and nominal fuel inputs of 300 Wth and 10 kWth, respectively. As oxygen carrier material, ground steel converter slag from the Linz–Donawitz process was used. This material is the second largest flow in an integrated steel mill, and it is available in huge quantities, for which there is currently limited demand. Steel converter slag consists mainly of oxides of Ca, Mg, Fe, Si and Mn. In the 300 W unit chemical-looping combustion experiments were conducted with model fuels syngas (50 vol% H2 in CO) and methane at varied reactor temperature, fuel input and oxygen-carrier circulation. Further, the ability of the oxygen-carrier material to release oxygen to the gas phase was investigated. In the 10 kW unit, the fuels used for combustion tests were steam-exploded pellets and wood char. The purpose of these experiments was to study more realistic biomass fuels and to assess the lifetime of the slag when employed as oxygen carrier. In addition, chemical-looping gasification was investigated in the 10 kW unit using both, steam-exploded pellets and regular wood pellets as fuels. In the 300 W unit, up to 99.9 % of syngas conversion was achieved at 280 kg/MWth and 900 °C, while the highest conversion achieved with methane was 60 % at 280 kg/MWth and 950 °C. The material’s ability to release oxygen to the gas phase, i.e., CLOU property, was developed during the initial hours with fuel operation, and the activated material released 1-2 vol% of O2 into a flow of argon between 850 °C and 950 °C. The material’s initial low density decreased somewhat during CLC operation. In the 10 kW, CO2 yields of 75-82 % were achieved with all three fuels tested in CLC conditions, while carbon leakage was very low in most cases, i.e., below 1 %. With wood char as fuel, at a fuel input of 1.8 kWth, a CO2 yield of 92 % could be achieved. The carbon fraction of C2-species was usually below 2.5 % and no C3-species were detected. During chemical-looping gasification investigation a raw gas was produced that contained mostly H2. The oxygen carrier lifetime was estimated to be about 110-170 h. However, due to its high availability and potentially low cost, this type of slag could be suitable for large-scale operation.
Internal Wage References and Wage Rigidity

Internal wage references are used to generate wage rigidity in labor market models. However, there is little knowledge about which features an internal reference has to fulfil in order to generate rigid wages. This paper includes profit measures as internal references in a unionized labor market and compares them to the Danthine and Kurmann (2007) model. I show that the way internal pay comparisons were modeled so far do not yield unambiguous rigidity results. In addition wage rigidity is related to the shape of the wage curve as well as to the level of pay and employment. JEL Classification: J51; J64; E24
Differences in the Susceptibility to Black Band Disease between Two Species of the Genus Diploria on the Reefs of Bermuda

On Bermuda reefs the coral Diploria labyrinthiformis is rarely documented with black band disease (BBD), while BBD-affected colonies of D. strigosa are common. Diploria labyrinthiformis on these reefs may be more resistant to BBD or less affected by prevailing environmental conditions that potentially diminish host defenses. Temperature and light are known to influence the incidence and progression of BBD. Infection experiments were conducted under the following experimental treatments: 1) 26°C, ambient light; 2) 30°C, ambient light; 3) 30°C, low light; and 4) 30°C, high light, to determine whether light and/or temperature affect BBD progression differently on these two species. Disease progression was slower at 26°C than at 30°C on both species at ambient light. Low light at 30°C counteracted the effect of elevated temperature on BBD lesion size for both species. High light at 30°C resulted in elevated BBD progression on colonies of D. strigosa and reduced progression on colonies of D. labyrinthiformis. The final affected area of BBD was significantly greater on colonies of D. labyrinthiformis in the 30°C ambient light treatment than in each of the other treatments. The area of the BBD lesions were significantly less on D. strigosa colonies in the 30°C low light treatment than on colonies at the same temperature with ambient
Is coarse woody debris a net sink or source of nitrogen in the red spruce - Fraser fir forest of the southern Appalachians, U.S.A.?

The red spruce (Picea rubens Sarg.) - Fraser fir (Abies fraseri (Pursh) Poir. ) forest of the southern Appala- chians contains a significant amount of coarse woody debris (CWD) that may affect the nitrogen (N) export signal in streams originating from this N-saturated system. Interpretation of the N sink versus source status of CWD of red spruce and Fraser fir was dependent on the method used. Over a chronosequence of decay, (1) N concentrations sug- geste daNs ink (i.e., an et gain of No f923% in red spruce and 563% in Fraser fir relative to N in live trees); (2) N contents that reflected changes in density suggested a smaller N sink (i.e., a net gain of N of 218% in red spruce and 125% in Fraser fir relative to N in live trees), but the stoichiometry of N and C suggested a N source in early stages of decay and a N source in the most advanced stage of decay only; and (3) N contents that reflected changes in vol- ume suggested a N source (i.e., a net N loss of -172% in red spruce and -122% in Fraser fir). The C/N ratios in CWD suggested that the shift from a N source to a N sink represented a shift from the mobilization of dissolved or- ganic N to the immobilization of ammonium N and (or) nitrate N. The magnitude of the net change in N contents in both red spruce and Fraser fir was amongst the highest reported in literature, suggesting that CWD plays a particularly important role in N dynamics in N saturated forests.
Telling Stories – A model for considering the impact of narrative practices on supporting identity and identification, based on a study of teacher educators in career transition

Identity for neophyte teacher educators has been shown by the literature to be problematic. As individuals transition from teacher to teacher educator their teacher identity can become a source of ‘credibility’ with the student teachers they work with and this can stall the development of a more integrated identity as a teacher educator (Boyd and Harris, 2010). This study adopts an adapted Professional Life History approach with six neophyte Teacher Educators, with one to three years’ experience in that role, in the expectation that such narrative practice might support them to develop their identity as a Teacher Educator and to engage in a process of ‘identification’. An analytical model that considers two binary dimensions, that of subjectivity / objectivity and structure / agency, operating within the narrative process is applied to the narrative events.
The ACER pollen and charcoal database

Quaternary records provide an opportunity to examine the nature of the vegetation and fire responses to rapid past climate changes comparable in velocity and magnitude to those expected in the 21st century. The best documented examples of rapid climate change in the past are the warming events associated with the Dansgaard-Oeschger (D-O) cycles during the last glacial period, which were sufficiently large to have had a potential feedback through changes in albedo and greenhouse gas emissions on climate. Previous reconstructions of vegetation and fire changes during the D-O cycles used independently constructed age models, making it difficult to compare the changes between different sites and regions. Here we present the ACER (Abrupt Climate Changes and Environmental Responses) global database which includes 93 pollen records from the last glacial period (73–15 ka) with a temporal resolution better than 1,000 years, 32 of which also provide charcoal records. A harmonized and consistent chronology based on radiometric dating (14C, 234U/230Th, OSL, 40Ar/39Ar dated tephra layers) has been constructed for 86 of these records, although in some cases additional information was derived using common control points based on event stratigraphy. The ACER database compiles metadata including geospatial and dating information, pollen and charcoal counts and pollen percentages of the characteristic biomes, and is archived in Microsoft AccessTM at doi:10.1594/PANGAEA.870867.
Detecting Relationship between Features and Sentiment Words using Hybrid of Typed Dependency Relations Layer and POS Tagging (TDR Layer POS Tags) Algorithm

Through online product reviews, consumers share their opinions, criticisms and satisfactions on the products they have purchased. However, the abundance of product reviews may be confusing and time-consuming for prospective customers as they read and analyze differing views before buying a product. The unstructured format of product reviews needs a sentiment mining approach in analyzing customers’ comments on a product and its features. In this paper, the researchers explore and analyze the hybrid role of typed dependency relations (TDR) and part-of-speech tagging (POST) in detecting the relation between features and sentiment words. The researchers have also created a list of combination rules using TDR and POST to serve as a guide in identifying the relation between features and sentiment words in sentences. Results have shown that the hybrid algorithm could assist in identifying such a relationship and improve performance.
Commodity futures returns: more memory than you might think!†

This paper investigates long-range dependence in 14 commodity and 3 other financial futures returns series from 1993 to 2009 and shows that long memory is a pervasive phenomenon in contrast to the extant evidence. Utilizing a semi-parametric wavelet-based estimator with time windows, the results provide overwhelming evidence of time-varying long-range dependence in all futures returns series. Structural break tests indicate multiple regimes of dependence, in the majority of which the persistence parameter is statistically significant. The results also provide evidence of predominantly negative parameter values which are known as anti-persistence. The latter is consistent with investor overreaction to shocks and suggests temporary departures from market efficiency.
Increase Data Characters to Construct the Molecular Phylogeny of the Drosophila auraria Species Complex

Previous phylogenetic analyses of the auraria species complex have led to conflicting hypotheses concerning their relationship; therefore the addition of new sequence data is necessary to discover the phylogeny of this species complex. Here we present new data derived from 22 genes to reconstruct the phylogeny of the auraria species complex. A variety of statistical tests, as well as maximum likelihood mapping analysis, were performed to estimate data quality, suggesting that all genes had a high degree of contribution to resolve the phylogeny. Individual locus was analyzed using maximum likelihood (ML), and the concatenated dataset (21,882 bp) were analyzed using partitioned maximum likelihood (ML) and Bayesian analyses. Separated analysis produced various phylogenetic relationships. Phylogenetic topologies from ML and Bayesian analysis based on concatenated dataset show that D. subauraria was well supported as the first species by separated analysis, concatenated dataset analysis, and some previous analysis, then followed by D. auraria and D. biauraria, D. quadraria and D. triauraria. The close relationships of D. quadraria and D. triauraria were consistent with most previous studies. The phylogenetic position of the D. auraria and D. biauraria will be resolved by more data sets.
An experimental demonstration of stem damage as a predictor of fire-caused mortality for ponderosa pine

We subjected 159 small ponderosa pine (Pinus ponderosa Dougl. ex P. & C. Laws.) to treatments designed to test the relative importance of stem damage as a predictor of postfire mortality. The treatments consisted of a group with the basal bark artificially thinned, a second group with fuels removed from the base of the stem, and an untreated control. Following prescribed burning, crown scorch severity was equivalent among the groups. Postfire mortality was significantly less frequent in the fuels removal group than in the bark removal and control groups. No model of mortal- ity for the fuels removal group was possible, because dead trees constituted <4% of subject trees. Mortality in the bark removal group was best predicted by crown scorch and stem scorch severity, whereas death in the control group was predicted by crown scorch severity and bark thickness. The relative lack of mortality in the fuels removal group and the increased sensitivity to stem damage in the bark removal group suggest that stem damage is a critical determinant of postfire mortality for small ponderosa pine.

Cadmium adsorption behavior of some soils from northern of Iran

Cadmium adsorption behavior (Cd) of soils is an important process which exerts a major influence on its uptake by plant roots. Cadmium (Cd) sorption characteristics of 20 surface soils (0-30 cm) with a wide range of soil physicochemical properties, was investigated. Two grams of each sample were equilibrated for 24h at laboratory temperature (25  2°C) with 40ml, 0.01M CaCl2 containing 5 to 500 mg Cd L -1 . Langmuir, Freundlich and Temkin adsorption isotherms were used to evaluate the trend of Cd adsorption. The data of Cd adsorption was well fitted to Langmuir and Freundlich adsorption isotherms. However, the fit to Langmuir adsorption model was closer than that of Freundlich. Multiple stepwise regression analysis indicated that, the adsorption capacity of the soils for Cd increased with an increase in pH, CEC and calcium carbonate equivalent (CCE).
The co-existence of recreational and artisanal fisheries in the central parts of the Danube and Sava rivers

Abstract The official data on recreational and artisanal fisheries in Croatia and Hungary were analysed. The data from Croatia relates to the entire Croatian section of the Danube River and to the section of the Sava River along the border with Bosnia and Herzegovina. The data from Hungary covers 60 km of the Danube River north of the Croatian border. Absolute catches in kilograms, as well as CPUE (kg per fisherman per year) by both groups in all three river sections varied from year to year without dramatic changes. Fishing with nets, artisanal fishermen differ from the anglers in two major ways: they are less selective and they catch bigger specimens. According to the official data, the existing ratio between recreational and artisanal fishermen in these three river sections does not negatively affect each other’s or overall fishing. Therefore, a conclusion can be drawn that medium-intensive artisanal fisheries qualify to co-exist with recreational fisheries.
Initialization of an ice-sheet model for present-day Greenland

Abstract We construct initial conditions for an ice flow model of the Greenland ice sheet (GrIS). GrIS has been losing mass at an increasing rate over the past two decades, and a significant proportion of this loss is due to dynamic thinning of narrow outlet glaciers. We solve an inverse problem to estimate poorly known basal and englacial parameters given observed geometry and surface velocities. A weighted cost function, resolved to 4 km in the interior of the ice sheet and 1 km in regions of fast-flowing ice at the margin, is minimized to find two-dimensional fields for a stiffness factor, which is a coefficient of the effective viscosity, and basal traction coefficient. Using these fields, we run the model under present-day climate to damp large-amplitude, short-wavelength fluctuations in the flux divergence. The time-dependent model uses an adaptive mesh with resolution ranging from 8 km of the base grid to 500 m in areas of fast-flowing ice to capture the behaviour of the main outlet glaciers. The ice discharge calculated from the initial conditions for GrIS and individual glaciers compares well with values calculated from observations.
Contamination of runoff waters with polycyclic aromatic hydrocarbons in the city of Siedlce

Abstract The paper presents the results of the research on content of 16 polycyclic aromatic hydrocarbons in samples of runoff waters collected in Siedlce city. The samples were collected in March, July and October 2015. The highest mean total concentration of 16 PAHs amounting to 12.54 μmolּdm-3 was determined in water samples collected at Łukowska Street, whereas the lowest concentrations (1.90 μmolּdm-3) were found in samples collected at Warszawska Street. In some samples, small amounts of benzo(a)pyrene were present; the average content ranged from 0.02 μmol⋅dm-3 at Warszawska Street to 0.20 μmolּdm-3 at Garwolińska Street.
GENETIC VARIABILITY, CHARACTER ASSOCIATION AND COMPONENT ANALYSIS IN UPLAND COTTON

To assess the extent of variability, heritability and genetic advance per cent in 36 hybrids revealed that the GCV, heritability in broad sense and genetic advance as per cent of mean values were comparatively high for lint yield, seed cotton yield, number of sympodia per plant and plant height indicating the operation of additive gene action for these four traits. The correlation analysis indictated that lint yield and plant height had positive and significant correlation with seed cotton yield, while days to first flowering and days to 50% boll opening had negative and significant association with seed cotton yield. Path coefficient analysis revealed that among all the characters studied, lint yield should receive greater emphasis in cotton improvement programmes as it contributes maximum direct effect and higher indirect effect through other characters.
Attitudes towards in vitro meat and how they can be influenced - An online experiment in the German population using Facebook-posts

Even though concerns about ethical, environmental and health-related issues have risen during the past years, the demand for meat is continuously rising due to the growing world population. One of the alternatives that have therefore been developed is in vitro meat, which is basically meat that has been grown in a lab. This study explored general attitudes towards in vitro meat and examined whether other people’s opinions that are expressed through a Facebook-post have an influence on potential consumers’ attitude. The study was set up in Germany using 133 participants who were divided into two experimental groups (provided with positive vs negative opinions) and a control group. Statistical analyses revealed no significant effect of the Facebook-post on people’s attitude. However, it was shown that gender and frequency of meat consumption were strong predictors of attitude. Males were shown to be more perceptive towards in vitro meat than females and people who never or very seldom eat meat were more willing to try in vitro meat. Despite a questionable effect of the manipulation and a high mortality rate, this study makes an important step and forms the basis for further research on the rather new topic of in vitro meat.
A Retrospective Review of the Relation of Ovarian Volume Measured by Transvaginal Ultrasound and Perimenopausal Transition to Menopause

Objective: To determine the relation of ovarian volume measured by transvaginal ultrasound and perimenopausal transition to menopause. Methodology: This was a retrospective cohort review of all transvaginal ultrasound measurements of ovarian volume among reproductive-aged non-pregnant women. Details on their age and menstrual cycle were obtained and menstrual pattern categorized as regular, irregular, less than 1 year of menopause or menopause. Results: A total of 301 patients were included with a mean age of 45.1 + 8.84 years. There was a significant decrease in mean volume of either ovary as age of the patient advanced. The ovarian volume dropped significantly between the age category of 30s and 50s (P<0.001). The mean age at onset of irregular menstrual pattern was 45.2 + 3.71 years with mean ovarian volume of 2.6 + 1.8cm 3 and 2.8 + 2.06cm 3 . The mean age of menopause was 55.0 + 2.59 years with a mean ovarian volume of 1.1 + 0.9cm 3 and 1.1 + 0.93cm 3 . At onset of irregular menstrual pattern, the ovarian volume dropped significantly (P<0.001). After the onset of irregular menstrual pattern, there was no further evidence to indicate significant decrease in ovarian volume in the succeeding changes in menstrual pattern. Conclusion: There was significant inverse correlation between advancing age and declining ovarian volume measured by transvaginal ultrasound. At onset of irregular menstrual pattern, the ovarian volume dropped significantly.
