20 Aug 2006TL;DR: It is proved that the optimal (α, k)-anonymity problem is NP-hard, and a local-recoding algorithm is proposed which is more scalable and result in less data distortion.
Abstract: Privacy preservation is an important issue in the release of data for mining purposes. The k-anonymity model has been introduced for protecting individual identification. Recent studies show that a more sophisticated model is necessary to protect the association of individuals to sensitive information. In this paper, we propose an (α, k)-anonymity model to protect both identifications and relationships to sensitive information in data. We discuss the properties of (α, k)-anonymity model. We prove that the optimal (α, k)-anonymity problem is NP-hard. We first presentan optimal global-recoding method for the (α, k)-anonymity problem. Next we propose a local-recoding algorithm which is more scalable and result in less data distortion. The effectiveness and efficiency are shown by experiments. We also describe how the model can be extended to more general case.

TL;DR: It was concluded that regulation of stride length is the fundamental problem in gait hypokinesia and the relative increase in cadence exhibited by PD subjects is a compensatory mechanism for the difficulty in regulating stride length.
Abstract: To identify the fundaamentall deficit in gait hypokinesia in Parkinson's disease (PD) we conducted a series of experiments that compared PD subjects with age- and height- matched controls in their capacity to regualte either stride length, cadence (steps per minute) or both parameters to three conditions. In the first condition the spatial and temporal parameters of gait were documented for slow, normal and fast walking. The seconde condition compared parkinsonian gait with the walking pattern of elderly controls whilst controlling for two movement speeds: fast (control preferred) speed and slow (PD preferred) speed. In the third condition we examined the ability of PD subjects to regulate one parameter (e.g. stride length) when the other two parameters (e.g. velocity and cadence) were held at control values. A total of 34 PD subjects and 34 matched controls were tested using a footswitch stride analysis system that measured the spatial and temporal parameters of gait for a series of 10 m walking trials. Parkinsonian subjects exhibited marked gait hypokinesia in each of the experiments. Although they retained the capacity to vary their gait velocity in a similar manner to controls, their range of response was reduced. Within the lower velocity range, PD subjects could vary their speed of walking by adjusting cadence and, to a lesser extent, stride length. However, when the speed of walking was controllled, the stride length was found to be shorter and the cadence higher in PD subjects than in controls. Stride length could not be upgraded by internal control mechanisms in response to a fixed cadence set for age and height-matched velocity. In contrast, cadence was readily modulated by external cues and by internal control mechanisms when stride length was fixed to the values obtained for age-and height-matched controls. It was concluded that regualation of stride length is the fundamental problem in gait hypokinesia and the relative increase in cadence exhibited by PD subjects is a compensatory mechanism for the difficulty in regulating stride length. These findings are discussed in the context of the hypothesized role of the basal ganglia in generating internal cues for the maintenance of the gait sequence and in relation to the structuring of movement rehabilitation strategies.

TL;DR: A survey of shareholders, accounting academics, stockbrokers, financial analysts, financial institutions, environmental lobby groups, industry associations and other groups performing a review or oversight function as discussed by the authors showed that the majority of the users surveyed believe environmental information to be material to their decisions and that they seek the disclosure of this information in corporate annual reports.
Abstract: Reports on the results of a survey of various groups of annual report users as to the importance, or “materiality”, of environmental information to decisions they may wish to make. Also investigates how environmental information is ranked in importance relative to various other items of social and financial information. The user groups surveyed comprise shareholders, accounting academics, stockbrokers and financial analysts, financial institutions, environmental lobby groups, industry associations and other groups performing a review or oversight function. Reports the results which indicate that the majority of the annual report users surveyed believe environmental information to be material to their decisions, and that they seek the disclosure of this information in corporate annual reports. Although the results show that the users typically believe that environmental information is material, they further indicate that the majority of the user groups rank environmental information behind traditional financial information such as profits, net assets, cash flows, and dividend payments.

TL;DR: A consistency model, with properties of convergence, causality preservation, and intention preservation, is proposed as a framework for consistency maintenance in real-time cooperative editing systems and an integrated set of schemes and algorithms are devised.
Abstract: Real-time cooperative editing systems allow multiple users to view and edit the same text/graphic/image/multimedia document at the same time for multiple sites connected by communication networks. Consistency maintenance is one of the most significant challenges in designing and implementing real-time cooperative editing systems. In this article, a consistency model, with properties of convergence, causality preservation, and intention preservation, is proposed as a framework for consistency maintenance in real-time cooperative editing systems. Moreover, an integrated set of schemes and algorithms, which support the proposed consistency model, are devised and discussed in detail. In particular, we have contributed (1) a novel generic operation transformation control algorithm for achieving intention preservation in combination with schemes for achieving convergence and causality preservation and (2) a pair of reversible inclusion and exclusion transformation algorithms for stringwise operations for text editing. An Internet-based prototype system has been built to test the feasibility of the proposed schemes and algorithms
