    Notes: Controlled-release fertilization with two formulations, Forestcote 22-4-6 + Minors and Gromax 21-6-2 + Minors, and dolomitic lime were evaluated for their capacity to facilitate establishment and enhance nutrition of bareroot Jeffrey pine (Pinus jeffreyi Grev. & Balf.) on an acidic Sierra Nevada surface mine. All amendments were applied at outplanting to the backfill of augered planting holes, with a low rate of 8 g and a high rate of 16 g per seedling for the two fertilizer formulations, whereas a single rate of 30 g was used for lime. Liming induced excessive seedling mortality throughout the study, whereas both fertilizer formulations also reduced survival but only as an interactive effect with the lime amendment. Growth stimulation by the fertilizer applications was readily apparent after three growing seasons, with the response to the high rate surpassing that to the low rate and the response to the Forestcote formulation exceeding that to Gromax. Conversely, the lime amendment depressed seedling growth, and it is likely that a propensity to exacerbate the stress imposed by dry growing season soils through interference with water uptake accounts for the overall poor performance of the seedlings that received this amendment. Improved N and P nutrition, with the former likely the most critical, was largely responsible for the growth stimulation resulting from fertilization. However, this treatment also suppressed the absorption of certain micronutrients as well as that of Al, and the amelioration of potential phytotoxicities may have also contributed to the favorable performance of fertilized seedlings. Further evidence for this conclusion was supplied by base cation/metallic element molar ratios involving Al and Mn, which were frequently increased by fertilization. In contrast, the influence of the lime amendment on seedling nutrition was marginal, with positive responses too infrequent to improve seedling performance.

    Notes: Induced mycorrhization of sweet birch (Betula lenta L.) by Pisolithus tinctorius (Pers.) Coker & Couch, as influenced by substrate fertility, was evaluated for its effects on seedling growth and physiology. Following a brief period in seed flats, seedlings were transplanted to mine spoil where they resided for 30 months, and three nutrition regimes were imposed throughout the study by application of differing nutrient solution concentrations. High fertility suppressed mycorrhizal formation by P. tinctorius but promoted that of other mycobionts. Pisolithus mycorrhization induced substantial aboveground and belowground growth as indicated by dimensions and mass for the former and mass and length for the latter but favoring root over shoot growth overall. Furthermore, these mycorrhizae were frequently able to compensate for the growth stimulation of higher nutrient additions. Measurements of xylem pressure potential and soil water potential indicated that water uptake was enhanced by P. tinctorius during simulated drought episodes of two durations and in subsequent recovery periods. Inoculated seedlings had higher foliar concentrations of critical nutrients, especially N, and lower concentrations of potentially phytotoxic metallic elements, particularly Mn, than uninoculated seedlings, although the latter response was absent in high fertility. Spoil analyses clearly revealed the influence of the nutrition regimes but also the effects of seedling uptake on substrate chemistry, and reinforced the findings of the foliar analysis concerning suppression of metal uptake by P. tinctorius. Collectively, these results suggest that P. tinctorius can provide sweet birch an array of physiological benefits that will permit this tree species to flourish on harsh substrates such as surface mine spoils without heavy application of chemical fertilizers.

    Notes: Abstract A comparison of a composted organic amendment, a controlled-release fertilizer, and induced mycorrhizal inoculation as affecting the establishment and nutrition of bareroot Jeffrey pine (Pinus jeffreyi Grev. & Balf.) was conducted on a Sierra Nevada surface mine. The soil amendments were applied at outplanting to the backfill of augered planting holes, with a low rate of 8 g and a high rate of 16 g per seedling for the fertilizer, Gromax 21-6-2 + Minors, whereas a single rate of 2.0 L was used for organic matter. Colonization by Pisolithus tinctorius (Pers.) Coker & Couch was induced by coating the root systems with basidiospores suspended in a gel carrier. The organic amendment especially, but also mycorrhizal inoculation, caused substantial seedling mortality, whereas survival was unaffected by controlled-release fertilization. Gromax applied at the high rate produced a 74% increase in shoot volume after three growing seasons, whereas the organic amendment reduced volume by 28%. Growth was unaffected by mycorrhizal treatment. The growth response to the 16-g Gromax application probably reflected enhanced N, P, and K nutrition and decreased concentrations of potentially toxic metallic elements, including Mn and Al among others, as revealed through foliar analysis. Because they were accompanied by growth reduction, nutritional responses to the organic amendment, which involved both macronutrients and trace elements, were of little consequence. Impaired water relations may account for the poor response to this amendment. Likewise, nutritional responses to mycorrhizal inoculation produced no discernible benefit in terms of seedling performance. An inoculation procedure that failed to induce substantially greater P. tinctorius colonization in inoculated than uninoculated seedlings, and that may have also impaired water relations, likely explains this result. Overall, these findings indicate that further research is needed before either the organic amendment or the mycorrhizal inoculation procedure used here can be used in forest restoration efforts on dry sites.

    Use of CCA in the Public Sector: Lessons From Australia’s Experience With Public Utilities (2000)

    Notes: The background to the widespread adoption by Australian public trading enterprises of a deprival value variant of current cost accounting reflects successive efforts to establish demanding rate of return targets, or to legitimise price increases, or to monitor the financial performance of PTEs on a national basis. The experience of three public utilities in implementing CCA is reviewed. This experience suggests that CCA valuation of infrastructure (using deprival or optimized deprival values) is unable to deliver financial data to permit valid cross-sectional and longitudinal comparisons of performance. Issues raised during the 1970s and 1980s debates about CCA were either ignored or overlooked.

    Notes: We present recent results obtained by the European Free Electron Laser (FEL) project at the ELETTRA storage ring. Coherent and tunable light was produced in the ultraviolet down to below 190 nm, the shortest lasing wavelength obtained so far with a FEL oscillator. The performance of the FEL is described, together with a series of technical solutions that have been adopted on it. These solutions increase its validity as a source for applications, and demonstrate the potential of FEL oscillators to become sources with features in the vacuum ultraviolet. © 2002 American Institute of Physics.

    Notes: Summary Oral transmucosal fentanyl citrate (OTF) was compared with midazolam as a premedicant in a prospective, randomised, placebo-controlled, double-blind trial. Eighty children (ASA grade 1or 2, aged 3–9 years) who presented for tonsillectomy were randomly allocated to receive either 2.5 ml OTF (15–20 µg.kg−1) in a lollipop format and 0.5 ml.kg−1 placebo syrup, or midazolam syrup (0.5 mg.kg−1) and a placebo lollipop (2.5 ml). The acceptability of sedation, anxiety and compliance with anaesthetic induction were assessed. The children were given an ‘emergence’ score for their recovery. Analgesia requirements, the incidence of vomiting, itching and any behavioural changes were assessed for 6 h postoperatively. Oral transmucosal fentanyl citrate was as effective as midazolam in aiding compliance with anaesthesia, but is significantly better in its appeal to children (p 〈 0.001) and emergence (p 〈 0.001) characteristics. In conclusion, OTF may be particularly useful as a premedicant in paediatric practice.

    Gaps in Guidelines on Audit Committees (2004)

    Notes: Since the 1940s, advocacy of the establishment of audit committees was undertaken by regulatory agencies, and subsequently by the accounting profession, and committees representing combinations of interest groups. Over time, this advocacy literature has reflected changing views about the key responsibilities of audit committees. Initially, audit committees were primarily concerned with negotiations with (or responding to) auditors, and reviewing financial statements prior to publication. Since the 1970s, formal guidelines or requirements have suggested additional responsibilities that involve oversight of the internal management of corporations. There is a pattern of renewed enthusiasm for enhanced corporate governance and for a stronger role for audit committees following spates of corporate crashes or disasters. Nevertheless, some of the lessons from those events continue to be ignored, so that arguably there are gaps in contemporary guidelines on audit committees. These gaps concern the need for audit committees to review the structure and design of delegations, and the adequacy of financial and operational information being provided to senior management and boards (particularly concerning subsidiaries and associated entities). These gaps are also reflected in the charters of the audit committees of Australia's top 200 listed entities. However, in some respects, Australian practice has gone beyond the recommendations embodied in recent guidelines. Drawing from literature and practice, this article proposes a model charter which, if adopted, may contribute to improvements in the effectiveness of audit committees.
