Support for diversity initiatives in organisations: An intergroup perspective

Despite institutional commitment to diversity initiatives (e.g., affirmative action), employees often harbour negative attitudes towards such initiatives and their beneficiaries. Dispositional variables (e.g., neo-sexism), have often been implicated in these negative reactions. We reason that more immediate group-based beliefs (e.g., subjective beliefs about the intergroup context), also shape attitudinal and behavioural reactions and that individual and group-based beliefs are rationalised through appeals to justice and fairness concerns. In this study using early career academics we examined the role of individual differences and socio-structural beliefs (about the stability, legitimacy and permeability of the intergroup situation), to feelings of relative deprivation, perceived justice and attitudes towards gender equity initiatives. Results provided support for the role of group-based beliefs and for the mediating role of justice concerns.

The role of dissolved organic matter bioavailability in promoting phytoplankton blooms in Florida Bay

The clear, shallow, oligotrophic waters of Florida Bay are characterized by low phytoplankton biomass, yet periodic cyanobacteria and diatom blooms do occur. We hypothesized that allochthonous dissolved organic matter (DOM) was providing a subsidy to the system in the form of bound nutrients. Water from four bay sites was incubated under natural light and dark conditions with enrichments of either DOM ( > 1 kD, 2×DOM) or inorganic nutrients (N+P). Samples were analyzed for bacterial numbers, bacterial production, phytoplankton biomass, phytoplankton community structure, and production, nutrients, and alkaline phosphatase (AP) activity. The influence of 2×DOM enrichment on phytoplankton biomass developed slowly during the incubations and was relatively small compared to nutrient additions. Inorganic nutrient additions resulted in an ephemeral bloom characterized initially as cyanobacterial and brown algae but which changed to dinoflagellate and/or brown algae by day six. The DIN:TP ratio decreased 10-fold in the N+P treatments as the system progressed towards N limitation. This ratio did not change significantly for 2×DOM treatments. In addition, these experiments indicated that both autotrophic and heterotrophic microbial populations in Florida Bay may fluctuate in their limitation by organic and inorganic nutrient availability. Both N+P and 2×DOM enrichments revealed significant and positive response in bioavailability of dissolved organic carbon (BDOC). Potential BDOC ranged from 1.1 to 35.5%, with the most labile forms occurring in Whipray Basin. BDOC at all sites was stimulated by the 2×DOM addition. Except for Duck Key, BDOC at all sites was also stimulated by the addition of N+P. BDOC was lower in the dry season than in the wet season (5.56% vs. 16.86%). This may be explained by the distinct chemical characteristics of the DOM produced at different times of year. Thus, both the heterotrophic and autotrophic microbial communities in Florida Bay are modulated by bioavailability of DOM. This has ramifications for the fate of DOM from the Everglades inputs, implicating DOM bioavailability as a contributing factor in regulating the onset, persistence, and composition of phytoplankton blooms.

Role of metalliferous mudstones and graphitic shales in the location, genesis, and paleoenvironment

The Cambrian Tally Pond volcanic belt in central Newfoundland contains numerous volcanogenic massive sulphide (VMS) deposits, prospects, and showings that are locally associated with metalliferous mudstones and/or graphitic shales. Deposits in the belt are bimodal felsic-type VMS that are both base metal- (e.g., Duck Pond, Boundary) and precious metal-enriched (e.g., Lemarchant). At the Lemarchant deposit metalliferous mudstones are genetically and spatially associated with mineralization, whereas the relationship of other mudstones and shales to massive sulphide mineralization is more intricate and remains not fully understood. Metalliferous mudstones represent a hiatus in the volcanic activity where the deposition of hydrothermal products dominated over the abiogenic background sedimentation and/or dilution by volcaniclastic-epiclastic material. Lithogeochemical signatures allow one to distinguish between predominantly hydrothermally or detritally (i.e., non-hydrothermal) derived material. Metalliferous mudstones with a significant hydrothermal component, like those at Lemarchant, have elevated Fe/Al and base-metal contents, compared to detrital shales, and shale-normalized negative Ce and positive Eu anomalies, indicative of deposition from high temperature (>250°C) hydrothermal fluids within an oxygenated water column. Mudstones and shales sampled from other locations in the Tally Pond volcanic belt have more variable signatures ranging from hydrothermal (signatures as above) to non-hydrothermal (no positive Eu-anomalies, flat REE patterns), with some that have mixed (hydrothermal and detrital) signatures. Both S and Pb isotopic compositions indicate that proximal sulphides hosted in mudstones immediately associated with massive sulphide mineralization within the Lemarchant deposit contain a higher proportion of sulphur derived from hydrothermal sources and processes, and have more juvenile lead contributions, when compared to sulphides distal (not associated with massive sulphides) from mineralization. Lead and Nd isotopic compositions of both whole rock and minerals in the Lemarchant mudstones indicate involvement of underlying crustal basement during massive sulphide formation and throughout the evolution of the Tally Pond belt. Metalliferous mudstones precipitated early in the massive sulphide depositional history, but also have undergone syn- and post-ore-forming processes and have a larger lateral extent than the mineralization. Using lithogeochemistry, whole rock and in situ stable and radiogenic isotopes it is possible to distinguish prospective vent proximal (immediately associated with massive sulphide mineralization) from less prospective distal (not associated with massive sulphides) depositional environments and to reconstruct the paleotectonic setting on a deposit- to regional-scale for the Lemarchant deposit and other mudstone-associated prospects in the Tally Pond volcanic belt.

Evaluation of the nutrient inputs to a coastal lagoon: the case of the Ria de Aveiro, Portugal

The Ria de Aveiro estuary-coastal lagoon system of northern Portugal is estimated to currently receive mean annual influxes of total nitrogen (N) and total phosphorus (P) of c. 6118 t y−1 and 779 t y−1, respectively, from its influent rivers. In low summer flows the mean N and P fluxes decrease to c. 10% of the annual average. The sewage contribution to the inland-derived N load on an annual basis is c. 5% but, during the summer low flow conditions, the sewage component increases to c. 65% of the total river loading. The sewage contribution to the inland-derived P load on an annual basis is c. 11% but, during the dry season, it is 1.2 times larger than the river-derived flux. The construction of a regional sewer system linked to a submarine outfall, due for completion in 2005, is expected to lead to a reduction in nutrient fluxes from inland to the lagoon of c. 15% for N and c. 26% for P relative to the present values. While this system will reduce the nutrient loading in the upper reaches of the lagoon, an increase in nutrients derived from the ocean is anticipated, due to the proximity of the outfall to the inlet.

Changing use and hydromorphological adjustment in a coastal lagoon–estuarine system, the Ria de Aveiro, Portugal

Today the Ria de Aveiro of northern Portugal has a hydromorphological regime in which river influence is limited to periods of flood. For most of the annual cycle, tidal currents and wind waves are the major forcing agents in this complex coastal lagoon–estuarine system. The system has evolved over two centuries from one that was naturally fluvially dominant to one that is today tidally dominant. Human influence was a trigger for these changes, starting in 1808 when its natural evolution was halted by the construction of a new inlet/outlet channel through the mobile sand spit that isolates it from the Atlantic Ocean. In consequence, tidal ranges in the lagoon increased rapidly from ~0.1 m to >1 m and continued to increase, as a result of continued engineering works and dredging, today reaching ~3 m on spring tides. Hydromorphological adjustments that have taken place include the deepening of channels, an increase in the area of inter-tidal flats, regression of salt marsh, increased tidal propagation and increased saline intrusion. Loss of once abundant submerged aquatic vegetation (SAV), due to increased tidal flows, exacerbated by increased recreational activities, has been accompanied by a change from fine cohesive sediments to coarser, mobile sediments with reduced biological activity.

Egg Quality of Tegal Ducks in Intensive Keeping Feed with Different Levels of Methionine and Lancang (Atlanta sp.)

The purpose of this research is to study the effect of combination levels of methionine-lancang (Atlanta sp.) in diet on egg quality of Tegal ducks. Eighty-one Tegal ducks early production period were used in this research. The treatments were arranged in a factorial (3x3). The first factor was level of synthetic methionine supplement (M) comprised of  m1: 0,00%, m2: 0,05%, and m3: 0,10%. The second factor was level of lancang (L), i.e. l1: 0,0%, l2; 2,0%, and l3: 4,0%. The variables observed were eggshell-thickness, haugh unit, and egg index. The result showed that the average eggshell-thickness was 0,335 ± 0,002 mm, range between 0,317 to 0,337 mm. The average of haugh unit was 92,054 ± 2,906 range between 85,767 to 99,095, and average of egg index was 76,58 ± 2,91, range between 73,79-81,37%. The interaction of methionine-lancang did not have significant effect on eggshell thickness, haugh unit, and egg index during the first two months egg production. Level of methionine significantly different (P<0,05) the haugh unit, but did not affect eggshell thickness and egg index. Level of  lancang has affect (P<0,05) eggshell thickness significant, but did not significant affect the haugh unit, and egg index. It can be concluded that increasing of synthetic methionine in the diet until 0,10% can improve haugh unit, and increase of lancang until 4,0% can improve eggshell thickness.
