    Personality Correlates of the Impostor Phenomenon: An Exploration of Gender Differences in Critical Needs

    The Impostor Phenomenon (IP) refers to the pervasive feeling of phoniness experienced by many high achieving individuals and the anxiety they feel as they encounter new challenges. This study investigates gender differences in the personalities of male and female Impostors using an instrument previously shown to be relevant to the IP, the Personality Research Form (PRF). The PRF, Clance\u27s IP Scale, and the Otis-Lennon Mental Abilities Test were administered to 63 subjects. The findings indicate that the IP in males is associated with high needs for Change, Defendance, Endurance, and Impulsivity and low need for Order. Among females the IP seems to be associated with high needs for Defendance and low needs for Affiliation, Change, Exhibition, Impulsivity, Nurturance, and Play. Contrary to its conceptualization as a phenomenon found among high achievers, the IP was also shown not to correlate with Impulsivity, Nurturance, and Play. Contrary to its conceptualization as a phenomenon found among high achievers, the IP was also shown not to correlate with grade point average. No differences were found on any variable between high-achieving and low-achieving PRF Impostors. Implications of this study and suggestions for further research are offered.

    Early Permian Seawater from the delta18O Record Of Fossil Bivalves: Seasonality And A Latitudinal Gradient

    The transition from a glaciated world to one that was ice-free makes the early Permian a time interval that in many ways mirrors the present, and hence there is great interest in constraining paleoclimate conditions over that transition. A common method for estimating ancient temperatures uses the oxygen isotope composition of marine carbonate, but this approach becomes significantly more complicated prior to the Cretaceous due to uncertainties about diagenesis and the isotopic composition of seawater, which has been hypothesized to be more depleted than during the Cenozoic. I use stable isotope compositions of sequentially microsampled accretionary calcite from fossil bivalves in SE Australia to evaluate Permian seawater isotope composition and water temperature seasonality. Co-occurring dropstones, diamicts, and glendonites constrain winter temperatures to near-freezing and hence allow calculations of water composition. Records from microsampled specimens of the bivalve Eurydesma, spanning roughly 11° of paleolatitude (North Sydney Basin, New South Wales to Hobart, Tasmania) reveal cyclic seasonal fluctuations in δ18Ocarb that vary with latitude. The δ13Ccarb values exhibit ~1 / of seasonal variation, and are in agreement with characteristically positive values published for the early Permian of ~5.5 /. The δ18Ocarb values vary seasonally by up to 3.3 /around a mean that decreases from -1.2 / to -1.75 / moving towards the pole; more enriched isotope values correspond to dark growth bands within the shells, suggesting slower growth in the winter months. Mean δ18O and seasonal amplitude both decrease with increasing paleolatitude, similar to an observed gradient in the modern high latitudes off the coast of Greenland. Decreasing seasonality is a reflection of decreasing summer temperatures with increasing latitude, while winter temperature minima are presumed to be constant because of freezing conditions. The decrease in mean δ18Ocarb with latitude reflects decreasing δ18Owater, similar to that observed over a similar latitudinal range off Greenland today. As with Greenland, the slope of the δ18O-latitude relationship is steeper than that seen in the global ocean today, indicating some contribution of isotopically negative fresh water. Whether this reflects progressive mixing with isotopically negative water from higher latitudes (e.g., the Arctic Ocean today) or similar amounts of runoff/precipitation at each location that itself is progressively more negative with latitude is as yet unclear, though significant departure from marine salinities is not observed

    Control and modelling of capillary flow of epoxy resin in aligned carbon nanotube forests

    This paper examines the mechanism of infiltration by capillary flow of epoxy resin into vertically-aligned carbon nanotube forests. The resin viscosity during curing was characterized by rheometry. Carbon nanotube forests were brought into contact with resin at a range of times during curing, therefore at a range of viscosities. The penetration of the resin into the forests was measured using electron microscopy, X-ray micro-computed tomography and energy-dispersive X-ray spectroscopy, the latter relying on a chromium-complex dye additive which acts as a marker for the presence of resin. Experimental results were compared to a simulation based on the Implicit Lucas–Washburn equation for capillary flow. It was found that prior to the resin gel point, the resin penetrates through the full height of the forest. Close to the gel point, the flow into the forest ceases, leaving unwetted regions of nanotubes. Understanding the relationship between resin flow in nanotube structures and the resin viscosity and curing has important application in the fabrication of nanocomposite materials. This “partial wetting” effect is a key requirement for a previously proposed method for the fabrication of carbon nanotube composites by additive manufacture (AM) which would provide strong interlayer reinforcement combined with the versatility of AM.Airbus Corp.

    Fabrication of Three Dimensional Layered Vertically Aligned Carbon Nanotube Structures and their Potential Applications

    This paper proposes a new technique for fabrication of vertically aligned carbon nanotube (VACNT) structures, controlled in shape, height and functionality, through continuous successive growth of VACNT layers by chemical vapour deposition (CVD) combined with patterning strategies. This was achieved by vacuum deposition of additional catalyst material onto the original VACNT “forest” layer. A second forest layer is then observed to grow underneath the first by CVD. It is proposed that the new catalyst material diffuses through the porous nanotube forest to coat the growth substrate underneath. The enhanced height, coating, and vertical alignment of the nanotube forests were verified by electron microscope observation. By repeating this process, aligned nanotube bi-layers and tri-layers were grown, producing a “stack” of nanotube layers. By using a “shadow mask” patterning technique to screen areas of the original forest from catalyst deposition, the growth can be confined to specific areas of the substrate. Potentially, these multilayer nanotube structures would have diverse applications as long composite reinforcements, p–n junctions for electronic devices, or to allow the production of near net shape complex multilayer nanotube structures
