An empirical analysis of the factors affecting bank crises in Japan : learning points for Bangladesh

This paper analyzes the factors that affect bank crises in Japan. There are numerous factors, qualitative and quantitative, identified from the analysis. For the quantitative analysis, the study employs the factor analysis, which detects three major components of factors that affect banking or financial crises in Japan. These are (i) common macro factors; (ii) bank sensitive micro factors; and (iii) household spending related factors. There are other factors, for example, policy dilemma, delayed or faulty deregulation measures and weak banking activities, which are not extracted from the factor analysis but adversely affect bank crises in Japan and hence discussed in details. The paper indicates some policy implications for the banking/financial sector of Bangladesh.

The 1947 bank nationalisation scheme : a prehistory of issues management?

Industry-wide crises emanating from legislative proposals are rare in Australia, and can be classed as once in a generation events, and so merit consideration and research. Currently, there is one such debate over the Mineral Resources Rent Tax, proposed by Prime Minister’s Julia Gillard’s government. Prior to this, the closest comparable event was the 1974 proposal for the establishment of a universal health insurance scheme. The 1947 proposal, by the Ben Chifley-led Labor Government, aimed to nationalise Australia’s banks, and it brought a crisis of massive proportions to Australia’s conservative financial service industry. Although the High Court of Australia finally found Chifley’s proposed legislation unconstitutional, the banks realised they must win in the court of public opinion, generate press coverage in favour of their position, and help defeat the Labor Government at the 1949 election. At the time, and for some decades to come, this was the most expensive and largest public relations campaign waged in Australia. After such a campaign there could be few Australians who could claim that they had not been exposed to the powers of public relations in a modern world. This paper looks at what can be learned from the banks’ collective response to the proposed nationalisation. It does so by applying contemporary issues management evaluation techniques.

New enhancements to cut, fade, and dissolve detection processes in video segmentation

We present improved algorithms for cut, fade, and dissolve detection which are fundamental steps in digital video analysis. In particular, we propose a new adaptive threshold determination method that is shown to reduce artifacts created by noise and motion in scene cut detection. We also describe new two-step algorithms for fade and dissolve detection, and introduce a method for eliminating false positives from a list of detected candidate transitions. In our detailed study of these gradual shot transitions, our objective has been to accurately classify the type of transitions (fade-in, fade-out, and dissolve) and to precisely locate the boundary of the transitions. This distinguishes our work from other early work in scene change detection which tends to focus primarily on identifying the existence of a transition rather than its precise temporal extent. We evaluate our improved algorithms against two other commonly used shot detection techniques on a comprehensive data set, and demonstrate the improved performance due to our enhancements.

A calibration protocol for population-specific accelerometer cut-points in children

Purpose

To test a field-based protocol using intermittent activities representative of children's physical activity behaviours, to generate behaviourally valid, population-specific accelerometer cut-points for sedentary behaviour, moderate, and vigorous physical activity.
Methods

Twenty-eight children (46% boys) aged 10–11 years wore a hip-mounted uniaxial GT1M ActiGraph and engaged in 6 activities representative of children's play. A validated direct observation protocol was used as the criterion measure of physical activity. Receiver Operating Characteristics (ROC) curve analyses were conducted with four semi-structured activities to determine the accelerometer cut-points. To examine classification differences, cut-points were cross-validated with free-play and DVD viewing activities.
Results

Cut-points of ≤372, >2160 and >4806 counts•min−1 representing sedentary, moderate and vigorous intensity thresholds, respectively, provided the optimal balance between the related needs for sensitivity (accurately detecting activity) and specificity (limiting misclassification of the activity). Cross-validation data demonstrated that these values yielded the best overall kappa scores (0.97; 0.71; 0.62), and a high classification agreement (98.6%; 89.0%; 87.2%), respectively. Specificity values of 96–97% showed that the developed cut-points accurately detected physical activity, and sensitivity values (89–99%) indicated that minutes of activity were seldom incorrectly classified as inactivity.
Conclusion

The development of an inexpensive and replicable field-based protocol to generate behaviourally valid and population-specific accelerometer cut-points may improve the classification of physical activity levels in children, which could enhance subsequent intervention and observational studies.

Comparing different accelerometer cut-points for sedentary time in children

Actigraph accelerometers are hypothesized to be valid measurements for assessing children's sedentary time. However, there is considerable variation in accelerometer cut-points used. Therefore, we compared the most common accelerometer sedentary cut-points of children performing sedentary behaviors. Actigraph Actitrainer uniaxial accelerometers were used to measure children's activity intensity (29 children, 5-11 years old) during different activities, namely playing computer games, nonelectronic sedentary games, watching television and playing outdoors. A structured protocol was the criterion for assessing the validity of four common cut-points (100, 300, 800, 1100 counts/minute). The median counts during all sedentary behaviors were below the lowest comparison cut-point of 100 cpm. The 75th percentile values for the sedentary behaviors were always below the cut-point of 300 cpm. Our results suggest that the cut-point of <100 cpm is the most appropriate.

Audit of the Douglas Hocking Research Institute bone bank : ten years of non-irradiated bone graft

Background:  An audit performed in the use of non-irradiated femoral head bone graft at the Geelong Hospital over a 10-year period. While it is thought the non-irradiated bone graft provides a better structural construct there is theoretical increased risk of infection transmission.

Methods:  We performed a retrospective review of prospectively collected data in the use of non-irradiated bone allograft used from the Geelong Hospital Douglas Hosking Research Institute bone bank over a 10-year period. The review was performed using data collected from the bone bank and correlating it with the patient’s medical record. All complications, including infections, related to the use of the allograft were recorded.

Results:  We found that over the 10 years to 2004 that 811 femoral heads were donated, with 555 being used over 362 procedures in 316 patients. We identified a total of nine deep infections, of which seven were in joint replacements. Overall this was a 2.5% deep infection rate, which was lowered to 1.4% if the previously infected joints that were operated on were excluded.

Conclusion:  The use of non-irradiated femoral head bone graft was safe in a regional setting.

Corporate governance and bank performance: evidence from Bangladesh

This study investigates the relationship between the corporate governance structure and performance of listed banks in Bangladesh. We find that board independence and board size have a significant positive impact on performance. However, female directors appear to have no impact on performance. Our evidence indicates that the extent of the managerial ownership level has a significant negative impact on bank performance. These results suggest that better corporate governance mechanisms are imperative for every banking company and should be encouraged for the interest of the investors and other stakeholders.

Predictive validity and classification accuracy of ActiGraph energy expenditure equations and cut-points in young children

Objectives
Evaluate the predictive validity of ActiGraph energy expenditure equations and the classification accuracy of physical activity intensity cut-points in preschoolers.

Methods
Forty children aged 4–6 years (5.3±1.0 years) completed a ~150-min room calorimeter protocol involving age-appropriate sedentary, light and moderate-to vigorous-intensity physical activities. Children wore an ActiGraph GT3X on the right mid-axillary line of the hip. Energy expenditure measured by room calorimetry and physical activity intensity classified using direct observation were the criterion methods. Energy expenditure was predicted using Pate and Puyau equations. Physical activity intensity was classified using Evenson, Sirard, Van Cauwenberghe, Pate, Puyau, and Reilly, ActiGraph cut-points.

Results
The Pate equation significantly overestimated VO2 during sedentary behaviors, light physical activities and total VO2 (P<0.001). No difference was found between measured and predicted VO2 during moderate-to vigorous-intensity physical activities (P = 0.072). The Puyau equation significantly underestimated activity energy expenditure during moderate-to vigorous-intensity physical activities, light-intensity physical activities and total activity energy expenditure (P<0.0125). However, no overestimation of activity energy expenditure during sedentary behavior was found. The Evenson cut-point demonstrated significantly higher accuracy for classifying sedentary behaviors and light-intensity physical activities than others. Classification accuracy for moderate-to vigorous-intensity physical activities was significantly higher for Pate than others.

Conclusion
Available ActiGraph equations do not provide accurate estimates of energy expenditure across physical activity intensities in preschoolers. Cut-points of ≤25counts⋅15 s−1 and ≥420 counts⋅15 s−1 for classifying sedentary behaviors and moderate-to vigorous-intensity physical activities, respectively, are recommended.
