Mainstream television, adolescent homosexuality, and significant silence

Abstract: The treatment of adolescent subjects on network television is exceedingly heterosexist; continuing adolescent characters are always heterosexual and the adolescent audience is addressed as if it were composed exclusively of heterosexual viewers. This symbolic annihilation of gay and lesbian youth exhibited by network television in the extreme, and by most mass media in general, can contribute to a dysfunctional isolation that is supported by the mutually reinforcing invisibility of homosexual adolescents on the television screen and in the real world. Such isolation and invisibility can be examined as a spiral of silence phenomenon. Spiral of silence theory—in conjunction with the third‐person effect, the distinctiveness postulate, and the concept of symbolic annihilation—outlines the reciprocal communication‐based conditions through which the oppression of gay and lesbian youth may be achieved. The social‐psychological mechanism of the spiral of silence also partially accounts for the inefficacy of oppos...

Corporate Branding through External Perception of Organizational Culture

Abstract: This paper suggests that there may be a relationship between the external perceptions of organizational culture and corporate branding as measured by reputation. Using an instrument based on the Organizational Culture Profile, 179 industry professionals evaluated eight culture dimensions in six well known Silicon Valley firms (Apple Computer, Cisco Systems, Hewlett Packard, Oracle, Sun Microsystems and 3 Com). Corporate Branding was measured by utilizing a reputation-measuring instrument. Reputations of the firms were obtained by using the six dimension results of Fombrun's Reputation Quotient Survey. Regression analysis was performed on 48 possible pair by pair reputation/culture dimension relationships. A total of 11 correlations were found significant. The findings suggest that in these six firms, the strategic resource of corporate brand (as measured by reputation) may partially reflect external perceptions of culture.

The phytoplankton bloom response to wind events and upwelled nutrients during the CoOP WEST study

Abstract: In the coastal waters off northern California, seasonal wind-driven upwelling supplies abundant nutrients to be processed by phytoplankton productivity. As part of the Coastal Ocean Processes: Wind Events and Shelf Transport (CoOP WEST) study, nutrients, CO 2 , size-fractionated chlorophyll, and phytoplankton community structure were measured in the upwelling region off Bodega Bay, CA, during May–June 2000, 2001 and 2002. The ability of this ecosystem to assimilate nitrate (NO 3 ) and silicic acid/silicate (Si(OH) 4 ) and accumulate particulate material (i.e. phytoplankton) was realized in all 3 years, following short events of upwelling-favorable winds, followed by periods of relaxed winds. This was observed as phytoplankton blooms, dominated by chlorophyll in cells greater than 5 μm in diameter, that reduced the ambient nutrients to zero. These communities were located over the near-shore shelf (

Dynamic conservation for migratory species.

Abstract: In an era of unprecedented and rapid global change, dynamic conservation strategies that tailor the delivery of habitat to when and where it is most needed can be critical for the persistence of species, especially those with diverse and dispersed habitat requirements. We demonstrate the effectiveness of such a strategy for migratory waterbirds. We analyzed citizen science and satellite data to develop predictive models of bird populations and the availability of wetlands, which we used to determine temporal and spatial gaps in habitat during a vital stage of the annual migration. We then filled those gaps using a reverse auction marketplace to incent qualifying landowners to create temporary wetlands on their properties. This approach is a cost-effective way of adaptively meeting habitat needs for migratory species, optimizes conservation outcomes relative to investment, and can be applied broadly to other conservation challenges.

Comparative phylogeography of woodland reptiles in California: repeated patterns of cladogenesis and population expansion.

Abstract: The ultimate goal of comparative phylogeographical analyses is to infer processes of diversification from contemporary geographical patterns of genetic diversity. When such studies are employed across diverse groups in an array of communities, it may be difficult to discover common evolutionary and ecological processes associated with diversification. In order to identify taxa that have responded in a similar fashion to historical events, we conducted comparative phylogeographical analyses on a phylogenetically and ecologically limited set of taxa. Here, we focus on a group of squamate reptiles (snakes and lizards) that share similar ecological requirements and generally occupy the same communities in the western USA. At a gross level, deep genetic division in Contia tenuis, Diadophis punctatus, Elgaria multicarinata, the Charina bottae complex, and Lampropeltis zonata are often concordant in the Transverse Ranges, the Monterey Bay and Sacramento-San Joaquin Delta region, and the southern Sierra Nevada in California. Molecular clock estimates suggest that major phyletic breaks within many of these taxa roughly coincide temporally, and may correspond to important geological events. Furthermore, significant congruence between the phylogeographies of E. multicarinata and L. zonata suggests that the succession of vicariance and dispersal events in these species progressed in concert. Such congruence suggests that E. multicarinata and L. zonata have occupied the same communities through time. However, across our entire multi-taxon data set, the sequence of branching events rarely match between sympatric taxa, indicating the importance of subtle differences in life history features as well as random processes in creating unique genetic patterns. Lastly, coalescent and noncoalescent estimates of population expansion suggest that populations in the more southerly distributed clades of C. tenuis, D. punctatus, E. multicarinata, and L. zonata have been stable, while populations in more northerly clades appear to have recently expanded. This concerted demographic response is consistent with palaeontological data and previous phylogeographical work that suggests that woodland habitat has become more restricted in southern California, but more widespread in the North during Holocene warming. Future phylogeographical work focusing on allied and ecologically associated taxa may add insight into the ecological and evolutionary processes that yield current patterns of genetic diversity.
