Rediscovery of Ooline, Cadellia pentastylis, near Gunnedah : notes on the habitat and ecology of this dry rainforest tree

Cadellia pentastylis F.Muell., (family Surianaceae), a dry rainforest tree with a conservation listing of Vulnerable at state and national levels, was first collected from the Gunnedah area by the botanical collector J.L. Boorman in 1907. We report the first record of Cadellia pentastylis from the Gunnedah area (30°58’49’’S, 150°15’15’’E) since 1907, and provide details of the community and habitat where it occurs, on the lower slopes of Black Jack Mountain. Although this population is one of the smallest in New South Wales, it is significant as it is at its southern distributional limit, and is found adjacent to semi-evergreen vine thicket, another type of dry rainforest, on the same hillslope. We list the New South Wales occurrences of this species and discuss aspects of its flowering phenology

Reducing Substance Abuse Stigma in Employment Application

A history of substance use and having a history of legal charges can be a barrier to employment. Available research shows individuals with a criminal history of substance related charges have greater difficulty obtaining employment due to the presence of substance abuse stigma and criminal history stigma. Research also shows that employers with higher levels of fundamentalism and conservativism are more likely to negatively evaluate applicants with a criminal history of substance charges. Furthermore, available research demonstrates employers in rural areas are more likely to deny employment to an individual with a legal history of substance charges based upon higher rates of familiarity within the community. Stigma research shows personal contact with a stigmatized population can reduce stigma. This study set out to determine if changing the response on the legal history section of an employment application would have an effect on mock employer’s evaluations of job applications. In order to examine this, 458 participants were randomly assigned to read an employment application in one of three conditions. The only difference in the applications was the legal history section, which varied as “none,” “possession of a controlled substance,” or “will discuss.” Participants also completed measures of substance use stigma, conservativism, and fundamentalism. Further, participants’ geographic region (rural vs. non-rural) was examined. Results showed the only significant predictor of not granting an interview was the presence of a legal charge. The findings demonstrated listing ‘will discuss’ on the legal history section reduces the chances of obtaining an interview. Implications of the current study indicate that personal values or rural status should not be a main focus of intervention when trying to reduce stigma for individuals with a legal history of substance charges. Limitations of the study include lack of a robust manipulation check and limited risk in granting an interview. Future studies should focus on research designs that incorporate a limited number of available interview opportunities, and examine whether other legal charges would have similar effects in employment application

THIRD PARTY EFFECTS OF AFFECTIONATE COMMUNICATION IN FAMILY SUBSYSTEMS: EXAMINING INFLUENCE ON AFFECTIONATE COMMUNICATION, MENTAL WELL-BEING, AND FAMILY SATISFACTION

This study examined the links between affectionate communication expressed within family dyads and affectionate communication expressed among other dyads, as well as individual reports of satisfaction with family life and mental well-being. Overall, the study showed that a child’s report of affectionate communication exchanged in the child/father subsystem is associated with mother’s satisfaction with family life. Additionally, mother reports of affectionate communication exchanged in the spousal relationships were positively associated with child reports of child/father affectionate communication exchanged. Finally, both perceptions of affectionate exchange in dyads outside and inside of one’s direct experience correlated with satisfaction with family life and mental well-being. The results offer new insights into the nature of affectionate relationships in families

A broad typology of dry rainforests on the western slopes of New South Wales

Dry rainforests are those communities that have floristic and structural affinities to mesic rainforests and occur in parts of eastern and northern Australia where rainfall is comparatively low and often highly seasonal. The dry rainforests of the western slopes of New South Wales are poorly-understood compared to other dry rainforests in Australia, due to a lack of regional scale studies. This paper attempts to redress this by deriving a broad floristic and structural typology for this vegetation type. Phytogeographical analysis followed full floristic surveys conducted on 400 m2 plots located within dry rainforest across the western slopes of NSW. Cluster analysis and ordination of 208 plots identified six floristic groups. Unlike in some other regional studies of dry rainforest these groups were readily assigned to Webb structural types, based on leaf size classes, leaf retention classes and canopy height. Five community types were described using both floristic and structural data: 1) Ficus rubiginosa–Notelaea microcarpa notophyll vine thicket, 2) Ficus rubiginosa–Alectryon subcinereus–Notelaea microcarpa notophyll vine forest, 3) Elaeodendron australe–Notelaea microcarpa–Geijera parviflora notophyll vine thicket, 4) Notelaea microcarpa– Geijera parviflora–Ehretia membranifolia semi-evergreen vine thicket, and 5) Cadellia pentastylis low microphyll vine forest. Floristic groupings were consistent with those described by previous quantitative studies which examined smaller portions of this study area. There was also general agreement between the present analytical study and a previous intuitive classification of dry rainforest vegetation throughout the study area, but little concurrence with a continental scale floristic classification of rainforest

Transgenerational Patterns of Communication Orientations and Depression Among Mothers and Adult Children

This study investigated intergenerational transmissions of conversation orientations, conformity orientations, and depressive symptoms among 235 (N = 470) mother–child dyads. The analysis revealed that mothers’ reports of conformity orientation in her family of origin positively predicted her child’s report of conformity orientation and conversation orientation. Moreover, maternal depressive symptoms predicted child reports of family communication climates, which in turn predicted child depressive symptoms. A mediation analysis showed a significant indirect effect from maternal depressive symptoms to child depressive symptoms through child reports of conformity orientation. Implications for transgenerational patterns of family communication climates and depressive symptoms are discussed

Electric Propulsion Applications and Impacts

Most space missions require on-board propulsion systems and these systems are often dominant spacecraft mass drivers. Presently, on-board systems account for more than half the injected mass for commercial communications systems and even greater mass fractions for ambitious planetary missions. Anticipated trends toward the use of both smaller spacecraft and launch vehicles will likely increase pressure on the performance of on-board propulsion systems. The acceptance of arcjet thrusters for operational use on commercial communications satellites ushered in a new era in on-board propulsion and exponential growth of electric propulsion across a broad spectrum of missions is anticipated. NASA recognizes the benefits of advanced propulsion and NASA's Office of Space Access and Technology supports an aggressive On-Board Propulsion program, including a strong electric propulsion element, to assure the availability of high performance propulsion systems to meet the goals of the ambitious missions envisioned in the next two decades. The program scope ranges from fundamental research for future generation systems through specific insertion efforts aimed at near term technology transfer. The On-Board propulsion program is committed to carrying technologies to levels required for customer acceptance and emphasizes direct interactions with the user community and the development of commercial sources. This paper provides a discussion of anticipated missions, propulsion functions, and electric propulsion impacts followed by an overview of the electric propulsion element of the NASA On-Board Propulsion program
