Forage Brassica use in New Zealand and Australia Farming Systems

Forage brassica, genus Brassica, are annual feed crops grown on farming enterprises throughout New Zealand and Australia. These crops provide a source of high-yielding, high-quality feed, which is particularly useful to complement pasture production during periods when pasture growth is reduced. There are six forage brassica species and subspecies of agricultural importance including bulb turnip, swede, kale, forage rape, leafy turnip, and raphanobrassica. All of these, as well as interspecific crosses and individual cultivars, offer a range of characteristics to fit various environmental and livestock production challenges. Consumption of forage brassica crops in ruminant animals may reduce methane emissions compared to traditional feed sources. Furthermore, recent technological developments using seed mutagenesis in breeding new forage brassica provide increased herbicide control of weed species. As with all feed sources, specific management, crop husbandry and animal health considerations apply. Overall, the use of forage brassica enables increased resilience in typical pasture-based farm systems

State and Local Taxation of Financial Institutions:An Opportunity for Reform

Forces at work in both public and private sectors may soon change the way state and local political subdivisions tax financial institutions. The market for financial services is changing dramatically. Governments have expanded substantially the scope of activities in which financial depositories may engage. The competitive environment for financial activities also is changing as general business corporations enter the financial services field, an area previously considered the exclusive domain of financial institutions. Financial institutions have increasing opportunities for interstate activity, which offers both risks and challenges. These changes have occurred during a period in which the extensive framework of state and federal governmental regulation and protection of financial activity has been curtailed substantially. At the same time that financial institutions adjust to the changing market for their services, state and local governments are attempting to address increasing revenue needs. Although the budget difficulties that state and local governments face are mainly unrelated to the financial industry, the governments\u27 financial crisis is magnified by an inability to collect taxes traditionally paid by financial depositories. Moreover, a series of Supreme Court and state court decisions have restricted the ability of the states to tax the principal or interest on federal obligations held by financial depositories. Partly because of the general fiscal crisis and partly because of these court decisions, a number of states are searching for a revised basis on which to tax financial institutions. State legislatures should consider carefully the changing market forces affecting the financial industry to determine the appropriate basis for taxation.This Article examines the legal developments, both in financial industry regulation and in federal limitations on state taxation, that have helped to shape the current market for financial services.T his analysis and a review of relevant tax policy issues suggest that the states\u27 interest in taxing the financial industry on a thorough but rational basis will be served best by a state income tax on financial institutions that is based on uniform jurisdictional rules and uniform apportionment standards

Instantiated Recoupling in Principals\u27 Enactment of Teacher Evaluations: Emotion Work and New Forms of Ceremonial Conformity in Educational Institutions

As accountability policies have proliferated and evolved in a number of organizational fields, recent scholarship in organizational sociology has paid close attention to the ways that accountability has forced tight coupling in a variety of organizations. Fewer recent studies examine efforts at ceremonial conformity that organizations may use to buffer internal practices from institutional pressures, or how organizations and their actors might attempt to engage in ceremonial conformity under newer accountability regimes. In this article, we examine how school principals enact state-mandated teacher evaluation policies with their teachers. To manage teachers\u27 stress caused by the evaluations, we find that principals often allow, and at times enable, teachers to put on a “dog and pony show” during formal evaluations, a performance that aligns with district instructional policies but deviates from their common everyday practices. We argue that this is a novel form of ceremonial conformity that we call instantiated recoupling

Developments in the Use of Plantain (\u3cem\u3ePlantago lanceolata\u3c/em\u3e) Cultivars in New Zealand Pastures

The use of pasture herbs, such as chicory, is commonplace in New Zealand in recent years. This has stimulated interest in other herb species such as plantain (Plantago lanceolata) that often occurs as a ubiquitous weed in temperate pastures throughout the world. In the last decade 2 improved commercial cultivars, Grasslands Lancelot (Rumball et al., 1997) and the erect, winter active Ceres Tonic (Stewart, 1996), have been bred in New Zealand for use in pastures. These cultivars have useful agronomic features that make them valuable for grazing. They are productive in mixtures, palatable to grazing animals, and tolerate a wide range of soils and dryland conditions (Stewart, 1996; Stewart & Charlton, 2003)

Examining Healthcare Institutions by Bringing Qualitative Data from Two Eras into Empirical Dialogue

In this paper, we argue that there is new insight to be gained by reexamining the classic text, Boys in White, in strategic ways. Specifically, we share excerpts from Boys in White with current medical students and ask for their reactions in qualitative interviews, examining the relevance (or lack thereof) of earlier meanings about professional training for current processes of professional training. We show how we have employed this technique in our current project revisiting Boys in White with current medical students, and discuss preliminary findings that reveal the potential of this technique for documenting evidence of macro-level forces in healthcare institutions using qualitative data on new doctors. We conclude with discussion of alternative approaches through which scholars could make use of this technique in future professional socialization scholarship that could shed light on dynamics of institutional persistence and change

Response of \u3cem\u3eArachis pintoi\u3c/em\u3e to Grazing Intensity When Associated with Different Grasses

Lack of legume persistence is one of the main reasons for poor utilisation of grass-legume pastures in the tropics. Arachis pintoi (forage peanut) is currently the most promising forage legume for the humid tropics, mainly because of good persistence under grazing (Grof, 1985; Fisher & Cruz, 1995). The objective of this work was to show how two accessions of A. pintoi react to increasing herbage allowance levels when associated with two different grasses

The value of computed tomographic (CT) scan surveillance in the detection and management of brain metastases in patients with small cell lung cancer.

One hundred and twenty-seven consecutive patients presenting with small cell lung cancer were entered into a whole-brain CT scan surveillance study, starting at presentation and repeating at 3-monthly intervals for 2 years as an alternative to prophylactic cranial irradiation (PCI). The aim of the study was to detect CNS metastases at an early asymptomatic stage in the hope that prompt CNS radiotherapy could achieve long-term control; at the same time unnecessary PCI with its potential long-term morbidity could be avoided. CNS metastases were found in 56 patients (44%) including 16 (13%) at diagnosis and 40 at a median of 4 months (range 1-27 months) after completing chemotherapy. No patient developed CNS disease while on chemotherapy. Thirty-six patients were asymptomatic at diagnosis (group A) but 20 developed clinical CNS relapse between scans (group B) (interval relapse). Despite prompt radiotherapy 56% of patients in group A and 60% of patients in group B died with active CNS disease. Likewise, there was no survival difference between patients in group A, group B or those who never developed CNS disease. Regular 3-month CT scan surveillance is therefore not an effective substitute for PCI

Beable trajectories for revealing quantum control mechanisms

The dynamics induced while controlling quantum systems by optimally shaped laser pulses have often been difficult to understand in detail. A method is presented for quantifying the importance of specific sequences of quantum transitions involved in the control process. The method is based on a ``beable'' formulation of quantum mechanics due to John Bell that rigorously maps the quantum evolution onto an ensemble of stochastic trajectories over a classical state space. Detailed mechanism identification is illustrated with a model 7-level system. A general procedure is presented to extract mechanism information directly from closed-loop control experiments. Application to simulated experimental data for the model system proves robust with up to 25% noise.Comment: Latex, 20 pages, 13 figure

Soil Nitrification Inhibition with Plantain (\u3ci\u3ePlantago lanceolata\u3c/i\u3e)

One strategy to reduce nitrogen losses from intensively grazed forage systems is to slow the first stage of soil nitrification, specifically inhibiting the microbial oxidation of ammonium to nitrite. Plantain (Plantago lanceolata) leaves and roots are known to contain several bioactive compounds (e.g., aucubin, catalpol and verbascoside) that may contribute to this inhibition. Recent laboratory studies indicate that this inhibition occurs via consumption by grazing animals of precursor bioactive compounds in aboveground biomass and their subsequent excretion as secondary metabolites in urine and/or via active exudation from the roots. Different cultivars of plantain have been shown to impart differing nitrification inhibition activity via both mechanisms. The urinary effect was assessed by determination of net soil nitrification in soil microcosms treated with urine from sheep fed a diet containing either perennial ryegrass or plantain. Analyses showed significant treatment effects on the rate of net nitrification and microbial community structure over time. A preliminary evaluation of the root exudate effect involved the collection of root exudates from six plantain cultivars grown in a hydroponic system. The assay of the root exudates against a pure culture of an ammonium-oxidising bacterium indicated differences in the amount of inhibition imparted by the exudates of each cultivar. The exact means of soil nitrification inhibition by either mechanism is as yet unconfirmed. However, it is likely that these compounds (or derivatives thereof) inhibit the first enzymatic step of nitrification directly, without harm to the soil microbiome as a whole
