    Firms as adaptive organizations : the case of Australian trading banks

    Full text link
    The conventional accounting notion of ‘going concern’ — that a firm will continue its business operations in the same manner indefinitely — has underpinned accounting practice for over one hundred years. This idea has provided a rationale for spreading costs over accounting periods and for deferring costs as assets in balance sheets. An alternative idea that is widely regarded as reliable in the literatures of economics and deliberate action is that firms continually adapt to changes in market and economic conditions. That is economic behaviour. The implications of that view of a firm for accounting have been systematically explored by Chambers (1966). While not examining those particular implications, many other accounting theorists have been critical of the conventional accounting idea of \u27going concern\u27 and of its impact on accounting practice. The two notions of ‘going concern’ - as static or adaptive enterprises - are examined by referring to the business operations of the four major Australian trading banks over the period 1983-1991. Banks were selected because they are commonly thought to be particularly ‘conservative’ organizations. The period 1983—1991 was chosen because it covers the era of deregulation of the Australian financial system. The evidence adduced by this study indicates that the Australian trading banks have continually adapted their organizational structures and business operations in the light of changes in technology, markets for financial services, government policies and domestic and global economic conditions. Illustrations of adaptive behaviour by banks ate drawn from their normal operating procedures such as the provision of products and services, loan services, acquisitions, sale of property, non-core banking operations and international banking. It is argued on analytical grounds that the cost basis of accounting does not yield financial statements that provide factual and up-to-date information about the financial capacity of firms to pay their debts and to continue trading generally; that is, to be going concerns. At any time, those financial capacities are determined by the amount of money commanded by a firm, including the money\u27s worth of its assets, and by its level of debt. It is concluded on empirical grounds that the Australian trading banks, at least, are adaptive entities

    Contexte : Les leucĂ©mies aiguĂ«s myĂ©loblastiques (LAM) ont un pronostic sombre, nĂ©cessitant de nouveaux traitements. Des facteurs pronostiques ont Ă©tĂ© validĂ©s dans le cadre de traitements conventionnels afin d adapter le traitement aux caractĂ©ristiques de chaque patient. L azacytidine est un agent dĂ©mĂ©thylant ayant dĂ©montrĂ© son efficacitĂ© dans les syndromes myĂ©lodysplasiques de haut risque dont l efficacitĂ© et les facteurs pronostiques de rĂ©ponse nĂ©cessitent d ĂȘtre explorĂ©s dans les LAM. MĂ©thodes : De maniĂšre rĂ©trospective, les patients du Nord-Pas-de-Calais et d Amiens traitĂ©s par azacytidine pour une LAM entre 2007 et 2011 ont Ă©tĂ© recensĂ©s. Une recherche de mutations de 12 gĂšnes sur ADN gĂ©nomique par biologie molĂ©culaire classique et sĂ©quençage ultra haut dĂ©bit a Ă©tĂ© rĂ©alisĂ©e afin d en Ă©valuer leur impact pronostique. RĂ©sultats : Dans cette cohorte de 102 patients, l Ăąge mĂ©dian Ă©tait de 68 ans [20-82]. Les LAM secondaires reprĂ©sentaient 51% des cas. 57% Ă©taient traitĂ©s en 1ere ligne, 20% en 2e ligne et 23% en 3e ligne et plus. 51% des patients prĂ©sentaient un risque cytogĂ©nĂ©tique dĂ©favorable. La blastose mĂ©dullaire mĂ©diane Ă©tait de 35% [9 ; 93]. Le taux de rĂ©ponse globale Ă©tait de 19% avec une durĂ©e mĂ©diane de 9,5 mois [2,5-38,7]. 9 patients Ă©taient allogreffĂ©s au terme du traitement par azacytidine. 39% des patients n atteignaient pas l administration des 4 cures dont 20% en raison d une progression de la maladie. La ligne thĂ©rapeutique apparaĂźt comme pronostique de la rĂ©ponse Ă  l azacytidine avec 26% de rĂ©ponse globale en premiĂšre ligne contre 9% en deuxiĂšme ligne et plus (p=0,03). IDH2 mutĂ© apparaĂźt comme un facteur pronostic pĂ©joratif de rĂ©ponse (40% vs 0%) parmi la recherche de mutations rĂ©alisĂ©es. La survie mĂ©diane de la cohorte Ă©tait de 7,1 mois [IC95 : 5,3-8,8]. La ligne thĂ©rapeutique avait un impact pĂ©joratif avec une survie mĂ©diane diminuĂ© Ă  5,3 mois en cas de 3e ligne et plus (P=0,04) et Ă  2,5 mois en cas d antĂ©cĂ©dent d allogreffe (p=0.02). A l inverse, la rĂ©alisation d une allogreffe Ă  l issu de traitement par azacytidine permet un allongement de la survie mĂ©diane Ă  12,1 mois (p=0,01). Conclusion : L azacytidine est un traitement qui est Ă  envisager chez le patient ĂągĂ© en premiĂšre ligne pour une LAM Ă  caryotype complexe permettant une prise en charge ambulatoire. L allogreffe Ă  conditionnement attĂ©nuĂ© devra ĂȘtre envisagĂ©e chaque fois que possible chez ces patients. IDH2 mutĂ© apparaĂźt dans une premiĂšre analyse avoir un impact pĂ©joratif sur l obtention de la rĂ©ponse.LILLE2-BU SantĂ©-Recherche (593502101) / SudocSudocFranceF

    Improve definition of titanium tandems in MR-guided high dose rate brachytherapy for cervical cancer using proton density weighted MRI

    BACKGROUND: For cervical cancer patients treated with MR-guided high dose rate brachytherapy, the accuracy of radiation delivery depends on accurate localization of both tumors and the applicator, e.g. tandem and ovoid. Standard T2-weighted (T2W) MRI has good tumor-tissue contrast. However, it suffers from poor uterus-tandem contrast, which makes the tandem delineation very challenging. In this study, we evaluated the possibility of using proton density weighted (PDW) MRI to improve the definition of titanium tandems. METHODS: Both T2W and PDW MRI images were obtained from each cervical cancer patient. Imaging parameters were kept the same between the T2W and PDW sequences for each patient except the echo time (90 ms for T2W and 5.5 ms for PDW) and the slice thickness (0.5 cm for T2W and 0.25 cm for PDW). Uterus-tandem contrast was calculated by the equation C = (S(u)-S(t))/S(u), where S(u) and S(t) represented the average signal in the uterus and the tandem, respectively. The diameter of the tandem was measured 1.5 cm away from the tip of the tandem. The tandem was segmented by the histogram thresholding technique. RESULTS: PDW MRI could significantly improve the uterus-tandem contrast compared to T2W MRI (0.42±0.24 for T2W MRI, 0.77±0.14 for PDW MRI, p=0.0002). The average difference between the measured and physical diameters of the tandem was reduced from 0.20±0.15 cm by using T2W MRI to 0.10±0.11 cm by using PDW MRI (p=0.0003). The tandem segmented from the PDW image looked more uniform and complete compared to that from the T2W image. CONCLUSIONS: Compared to the standard T2W MRI, PDW MRI has better uterus-tandem contrast. The information provided by PDW MRI is complementary to those provided by T2W MRI. Therefore, we recommend adding PDW MRI to the simulation protocol to assist tandem delineation process for cervical cancer patients

    Patterns of periodontal disease progression based on linear mixed models of clinical attachment loss

    AimThe goal of the present longitudinal cohort study was to examine patterns of periodontal disease progression at progressing sites and subjects defined based on linear mixed models (LMM) of clinical attachment loss (CAL).Materials and MethodsA total of 113 periodontally healthy and 302 periodontitis subjects had their CAL calculated bimonthly for 12 months. LMMs were fitted for each site and the predicted CAL levels used to categorize their progression state. Participants were grouped based on the number of progressing sites into unchanged, transitional and active subjects. Patterns of periodontal disease progression were explored using descriptive statistics.ResultsProgression occurred primarily at molars (50% of progressing sites) and inter‐proximal sites (72%), affected a higher proportion of deep than shallow sites (2.7% versus 0.7%), and pocketing was the main mode of progression (49%). We found a low level of agreement (47%) between the LMM and traditional approaches to determine progression such as change in CAL ≄3 mm. Fourteen per cent of subjects were classified as active and among those 93% had periodontitis. The annual mean rate of progression for the active subjects was 0.35 mm/year.ConclusionProgressing sites and subjects defined based on LMMs presented patterns of disease progression similar to those previously reported in the literature.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/142020/1/jcpe12827.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/142020/2/jcpe12827_am.pd
