Work does not speak for itself:Examining the incremental validity of personal branding in predicting knowledge workers’ employability

The changing context of contemporary knowledge work, including the massive adoption of home office work arrangements and a great resignation, calls for new research on the employability of knowledge workers. In this paper, we suggest that knowledge workers can no longer rely on developing their human capital and being intrapreneurial at work to secure their employability. With the aim to offer a new perspective, we test the incremental validity of personal branding in predicting employability over and above established predictors (i.e., human capital and intrapreneurship behaviours) and test the relationships in three studies (total N = 883), consisting of a supervisor sample (Study 1), a student sample (Study 2), and a time-lagged employee sample (Study 3). Results show that personal branding explains variance in employability over and above human capital and intrapreneurship behaviours. The results also show that the relationship between personal branding and employability is fully mediated by personal brand equity. The paper concludes with a discussion of the opportunities the concept of personal branding offers for employability research in the context of the contemporary world of work

Bleeding Diathesis in Fawn Hooded Rats:Possible Implications for Invasive Procedures and Refinement Strategies

The Fawn hooded (FH) rat is commonly used in biomedical research. It is widely acknowledged that the FH rat has a bleeding disorder; leading to abundant bleedings. Although this bleeding disorder is investigated to model the storage pool defect; its impact on commonly performed invasive laboratory procedures has not yet been described. Our research group experienced clinically significant consequences of this bleeding disorder following invasive procedures (including intraperitoneal injections and neurocranial surgery) in the Rjlbm: FH stock. The clinical consequences of the surgical and anesthetic protocols applied; are described including the subsequent procedural refinements applied to minimize the impact of this disorder. It is strongly recommended to take the bleeding diathesis into account when performing invasive procedures in FH rats and to apply the suggested refinement of procedures

Maximal Sharing in the Lambda Calculus with letrec

Increasing sharing in programs is desirable to compactify the code, and to avoid duplication of reduction work at run-time, thereby speeding up execution. We show how a maximal degree of sharing can be obtained for programs expressed as terms in the lambda calculus with letrec. We introduce a notion of `maximal compactness' for lambda-letrec-terms among all terms with the same infinite unfolding. Instead of defined purely syntactically, this notion is based on a graph semantics. lambda-letrec-terms are interpreted as first-order term graphs so that unfolding equivalence between terms is preserved and reflected through bisimilarity of the term graph interpretations. Compactness of the term graphs can then be compared via functional bisimulation. We describe practical and efficient methods for the following two problems: transforming a lambda-letrec-term into a maximally compact form; and deciding whether two lambda-letrec-terms are unfolding-equivalent. The transformation of a lambda-letrec-term $L$ into maximally compact form $L_0$ proceeds in three steps: (i) translate L into its term graph $G = [[ L ]]$; (ii) compute the maximally shared form of $G$ as its bisimulation collapse $G_0$; (iii) read back a lambda-letrec-term $L_0$ from the term graph $G_0$ with the property $[[ L_0 ]] = G_0$. This guarantees that $L_0$ and $L$ have the same unfolding, and that $L_0$ exhibits maximal sharing. The procedure for deciding whether two given lambda-letrec-terms $L_1$ and $L_2$ are unfolding-equivalent computes their term graph interpretations $[[ L_1 ]]$ and $[[ L_2 ]]$, and checks whether these term graphs are bisimilar. For illustration, we also provide a readily usable implementation.Comment: 18 pages, plus 19 pages appendi

Use of Polyphosphate to Decrease Uranium Leaching in Hanford 300 Area Smear Zone Sediments

The primary objective of this study is to summarize the laboratory investigations performed to evaluate short- and long-term effects of phosphate treatment on uranium leaching from 300 area smear zone sediments. Column studies were used to compare uranium leaching in phosphate-treated to untreated sediments over a year with multiple stop flow events to evaluate longevity of the uranium leaching rate and mass. A secondary objective was to compare polyphosphate injection, polyphosphate/xanthan injection, and polyphosphate infiltration technologies that deliver phosphate to sediment

Asylum seeker’s ‘brain death’ shows failure of care and of democracy

The news that Hamid Kehazaei, a 24-year-old Iranian asylum seeker detained on Manus Island, has been diagnosed as brain dead following his transfer to the Mater Hospital in Brisbane is a tragedy. That it is a tragedy for this young man and his family is unquestionable – but the extent of this tragedy may be much more pervasive than we realise. If the emerging details of his case are correct, Kehazaei developed septicaemia as a complication of cellulitis (skin and soft-tissue infection) arising from a cut in his foot. This, in itself, is disturbing. Severe infection can result in brain death – either from infection of the brain itself (meningitis, encephalitis or brain abscess), or from brain injury due to a lack of oxygen resulting from cardiac arrest (as appears to be the case here), or from reduced blood supply to the brain. Yet it is very uncommon, especially in a young, previously healthy man. Such a case could occur in Australia and has been described in 2012 in young Indigenous adults in Central Australia. Nevertheless, severe sepsis resulting from a foot infection is preventable. And a case like this occurring in an Australian national would raise serious questions about the appropriateness of the antibiotics used and the timeliness of care. Most cases of brain death result from traumatic brain injury, stroke or lack of oxygen to the brain following asphyxia, near-drowning, or prolonged cardiopulmonary resuscitation. What happened to Hamid Kehazaei raises concerns about the adequacy of care provided to him during initial treatment, including wound care and antibiotics, and how soon he was transferred to expert medical care, first to Port Moresby and subsequently to Brisbane. If this young man became ill and had his brain die while seeking asylum in Australia and while in our care, then we must examine the details of his case and ask ourselves not only whether it was preventable but whether our policies and processes actually contributed to his death

Participant music listening behaviours in interactive multimedia music instruction

While emerging technologies such as interactive multimedia are increasingly being employed in computerised music instruction, understanding of participant music listening behaviours in interactive multimedia music instruction is currently very limited. With the aim of elucidating music listening behaviour, the central concern of this work is to identify and explain participant interactions with the audio components of interactive multimedia music instruction. The investigation employs a novel documentation procedure, which extends the application of digital audio recording technology, to provide a finely calibrated analysis of the audio activity of a sample of 20 undergraduate music education majors during individual sessions with two commercially-available interactive multimedia music instruction programs. Graphically-based Sound Activity Profiles, which the researcher developed specifically for the current investigation, characterise and summarise participant interactions with audio components, while an analysis of questionnaire responses and follow-up interview transcripts provides supplementary information that further explains participants' music listening behaviours. The results of the investigation show that music listening behaviours during the study sessions were highly variable. While extensive participant interaction with music examples occasionally reflected attentive music listening behaviours, many study sessions were characterised by brief, fragmentary music excerpts and lengthy periods of silence. Participants spent as little as five percent of their session time listening to music and as much as 88 percent of the session time in silence. A substantial number of the study cohort frequently interrupted the music examples they had activated. Participants' perceptions of the extent of their interaction with music examples were frequently inaccurate, as subjects often substantially overestimated the amount of session time they had spent listening to music. The study findings suggest that many interactive multimedia music instruction participants would benefit from interventions that elicit more extensive and prolonged interaction with music examples. Accordingly, recommendations include a call for research to develop and test software designs that incorporate automated monitoring of session audio activity so that dynamic on-screen information about music listening behaviour can be provided to interactive multimedia music instruction participants. Such information may encourage participants to modify inappropriate music listening behaviours

Fate and transport of volatile organic compounds in glacial till and groundwater at an industrial site in Northern Ireland

Volatile organic compound (VOC) contamination of subsurface geological material and groundwater was discovered on the Nortel Monkstown industrial site, Belfast, Northern Ireland. The objectives of this study were to (1) investigate the characteristics of the geological material and its influences on contaminated groundwater flow across the site using borehole logs and hydrological evaluations, and (2) identify the contaminants and examine their distribution in the subsurface geological material and groundwater using chemical analysis. This report focuses on the eastern car park (ECP) which was a former storage area associated with trichloroethene (TCE) degreasing operations. This is where the greatest amount of volatile organic compounds (VOCs), particularly TCE, were detected. The study site is on a complex deposit of clayey glacial till with discontinuous coarser grained lenses, mainly silts, sands and gravel, which occur at 0.45-7.82 m below ground level (bgl). The lenses overall form an elongated formation that acts as a small unconfined shallow aquifer. There is a continuous low permeable stiff clayey till layer beneath the lenses that performs as an aquitard to the groundwater. Highest concentrations of VOCs, mainly TCE, in the geological material and groundwater are in these coarser lenses at similar to 4.5-7 m bgl. Highest TCE measurements at 390,000 mu g L-1 for groundwater and at 39,000 mu g kg(-1) at 5.7 m for geological material were in borehole GA19 in the coarse lens zone. It is assumed that TCE gained entrance to the subsurface near this borehole where the clayey till was thin to absent above coarse lenses which provided little retardation to the vertical migration of this dense non-aqueous phase liquid (DNAPL) into the groundwater. However, TCE is present in low concentrations in the geological material overlying the coarse lens zone. Additionally, VOCs appear to be associated with poorly drained layers and in peat < 3.0 m bgl in the ECP. Some indication of natural attenuation as VOCs degradation products vinyl chloride (VC) and dichloromethane (DCM) also occur on the site

Field emission in ordered arrays of ZnO nanowires prepared by nanosphere lithography and extended Fowler-Nordheim analyses

A multistage chemical method based on nanosphere lithography was used to produce hexagonally patterned arrays of ZnO vertical nanowires, with 1 lm interspacing and aspect ratio 20, with a view to study the effects of emitter uniformity on the current emitted upon application of a dc voltage across a 250 lm vacuum gap. A new treatment, based on the use of analytical expressions for the image-potential correction functions, was applied to the linear region below 2000 V of the Fowler-Nordheim (FN) plot and showed the most suitable value of the work function / in the range 3.3–4.5 eV (conduction band emission) with a Schottky lowering parameter y ~ 0.72 and a field enhancement factor c in the 700–1100 range. A modeled c value of 200 was calculated for an emitter shape of a prolate ellipsoid of revolution and also including the effect of nanowire screening, in fair agreement with the experimental value. The Fowler-Nordheim current densities and effective emission areas were derived as 1011 Am2 and 1017 m2, respectively, showing that field emission likely takes place in an area of atomic dimensions at the tip of the emitter. Possible causes for the observed departure from linear FN plot behavior above 2000 V were discussed

Experimental Plan: 300 Area Treatability Test: In Situ Treatment of the Vadose Zone and Smear Zone Uranium Contamination by Polyphosphate Infiltration

The overall objectives of the treatability test is to evaluate and optimize polyphosphate remediation technology for infiltration either from ground surface, or some depth of excavation, providing direct stabilization of uranium within the deep vadose and capillary fringe above the 300 Area aquifer. Expected result from this experimental plan is a data package that includes: 1) quantification of the retardation of polyphosphate, 2) the rate of degradation and the retardation of degradation products as a function of water content, 3) an understanding of the mechanism of autunite formation via the reaction of solid phase calcite-bound uranium and aqueous polyphosphate remediation technology, 4) an understanding of the transformation mechanism, identity of secondary phases, and the kinetics of the reaction between uranyl-carbonate and –silicate minerals with the polyphosphate remedy under solubility-limiting conditions, 5) quantification of the extent and rate of uranium released and immobilized based on the infiltration rate of the polyphosphate remedy and the effect of and periodic wet-dry cycling on the efficacy of polyphosphate remediation for uranium in the vadose zone and capillary fringe, and 6) quantification of reliable equilibrium solubility values for autunite under hydraulically unsaturated conditions allowing accurate prediction of the long-term stability of autunite. Moreover, results of intermediate scale testing will quantify the transport of polyphosphate and degradation products, and yield degradation rates, at a scale that is bridging the gap between the small-scale UFA studies and the field scale. These results will be used to test and verify a site-specific, variable saturation, reactive transport model and to aid in the design of a pilot-scale field test of this technology. In particular, the infiltration approach and monitoring strategy of the pilot test would be primarily based on results from intermediate-scale testing. Results from this experimental plan will be documented in a PNNL report
