    Asset recognition and probabilistic judgments

    With the issuing of Statement of Accounting Concepts 4 on the definition and recognition of elements of financial statements, research into the possible ramifications of the application of recognition criteria in that statement is timely. Using 60 experienced Australian auditors as subjects, this study provides information on the numerical equivalents of uncertainty expressions such as 'beyond any reasonable doubt' and 'virtually certain' (as per the asset-recognition criteria of AASB 1020), and 'probable' (as per Statement of Accounting Concepts 4). In addition, it compares the decisions made by auditors under the criteria included in AASB 1020 and SAC 4. The results indicate that the regognition criteria in AASB 1020 are a higher test of stringency for the recognition of assets than those adopted in the new SAC 4

    Using the discrete wavelet transform in assessing the effectiveness of rehabilitation in patients after ACL reconstruction

    Purpose: The purpose of the current study was to assess the effectiveness of rehabilitation in patients after anterior cruciate ligament reconstruction (ACLR) using a wavelet analysis of the torque-time curve patterns of the extensors of the affected knee. The analysis aimed at the quantitative evaluation of irregularities in these torque-time patterns. Methods: The study involved a group of 22 men who had had ACL reconstruction. The torque-time characteristics were recorded 3, 6 and 12 months after the surgery by an isokinetic dynamometer. They were then examined using the orthogonal Daubechies 4 (Db 4) and biorthogonal Bior 3.1 wavelets. Results: A statistical analysis of the results revealed significant differences in values of the high-frequency energy stored in the details of the signal from the dynamometer between the first and last measurements, both for the Db 4 ( p ≤ 0.023) and Bior 3.1 ( p ≤ 0.01) wavelets. These differences were found in 73% of patients whose curve patterns were analysed using the Db 4 wavelet and in 82% of patients in the case of the Bior 3.1 wavelet. Conclusions: The wavelet transform proved to be an effective research tool in the qualitative evaluation of irregularities occurring in the curve patterns of the torque generated by the extensors of the ACL reconstructed knee. The findings of the study suggest that time-frequency analyses of these characteristics can be of practical importance, as they help assess the state of the patient’s knee joint and his progress in rehabilitation after ACLR

    Early results of one-stage knee extensor realignment and autologous osteochondral grafting

    We treated 49 patients with recurrent patellar dislocations or persistent patellar subluxations. Chondral defects were graded according to the International Cartilage Repair Society (ICRS). Thirty patients (group I) had chondral defects grade I or II, and 19 patients (group II) had chondral defects grade III or IV. All patients were treated with proximal and distal realignment of the knee extensor mechanism, but group II also had a simultaneous autologous osteochondral grafting of the chondral defect. Patients were followed for 2 years and clinically assessed using the Marshall score comparing the two groups. Apart from a slower recovery in group II, the clinical and functional results were almost the same at the final follow-up
