Strikes Through The Prism Of Duties: Is There A Fundamental Duty To Strike Under The Indian Constitution?, Shubhankar Dam Jan 2004

Strikes Through The Prism Of Duties: Is There A Fundamental Duty To Strike Under The Indian Constitution?, Shubhankar Dam

Research Collection Yong Pung How School Of Law

Much of the debates on the legality of strikes under the Indian Constitution has been on the issue of a right to strike. This paper argues that the constitutionality of strikes may be analysed through the prism of duties, i.e. fundamental duties under Part IVA of the Constitution. Strikes were an integral part of the ideals that inspired India's national struggle against imperialism. And, in this sense, when article 51A exhorts Indians to cherish and follow the noble ideals that inspired our freedom struggle, it includes a fundamental duty to strike. Invoking the philosophy of Mahatma Gandhi, the paper argues …

The Structure Of Affect: Reconsidering The Relationship Between Negative And Positive Affectivity, Russell Cropanzano, Howard M. Weiss, Jeff M. S. Hale, Jochen Reb

Research Collection Lee Kong Chian School Of Business

During the past decade organizational scientists have devoted considerable research attention to the topic of workplace affect. Despite important advances, continued progress depends on a better understanding of the structure of affective experience. The goal of this paper is to review progress to date. In particular, we review evidence pertaining to four constructs that have been widely used to organize research on affect: positive affectivity, negative affectivity, hedonic tone, and affect intensity. We review various structural models pertaining to these four constructs, devoting special attention to integrative frameworks and future research needs. Corresponding au

Design And Analysis Of Cylindrical Antiresonant Reflecting Optical Waveguide, Chyng Wen Tee, S. F. Yu Dec 2003

Design And Analysis Of Cylindrical Antiresonant Reflecting Optical Waveguide, Chyng Wen Tee, S. F. Yu

Research Collection Lee Kong Chian School Of Business

A field-transfer matrix method is developed to analyze the modal characteristics of cylindrical multilayered waveguides with axis-symmetric geometry. A new design rule for cylindrical antiresonant reflecting optical waveguides (ARROWs), based on a three-step design process, is also proposed to minimize the radiation loss of the fundamental leaky mode. In addition, a simple approach is suggested to estimate the optimum core diameter of the cylindrical ARROWs for optimum radiation loss and radiation loss margin. Hence, it can be shown that an extra high index cladding layer is good enough to reduce the radiation loss as well as to maintain a reasonably …

Modularity And The Product Lifecycle, Peter Cebon, Oscar Hauptman, Chander Shekhar

Research Collection Lee Kong Chian School Of Business

Product lifecycle theory, which underlies theories of technical innovation in economics, strategy, marketing, and operations management, is based implicitly on the assumption that products are integrated wholes. The modularization of products undermines the specific synergies which drive the product lifecycle, and this undermining has impacts spanning from the structure of individual organizations to the structure of economies and the definition of industries.

Score Tests For Inverse Gaussian Mixture, Zhenlin Yang Dec 2003

Score Tests For Inverse Gaussian Mixture, Zhenlin Yang

Research Collection School Of Economics

The mixed inverse Gaussian given by Whitmore (Scand. J. Statist., 13, 1986, 211–220) provides a convenient way for testing the goodness-of-fit of a pure inverse Gaussian distribution. The test is a one-sided score test with the null hypothesis being the pure inverse Gaussian (i.e. the mixing parameter is zero) and the alternative a mixture. We devise a simple score test and study its finite sample properties. Monte Carlo results show that it compares favourably with the smooth test of Ducharme (Test, 10, 2001, 271-290). In practical applications, when the pure inverse Gaussian distribution is rejected, one is interested in making …

How Are Social Identities Linked To Self-Conception And Intergroup Orientation? The Moderating Effect Of Implicit Theories, Ying-Yi Hong, Gloria Chan, Chi-Yue Chiu, Rosanna Y. M. Wong, Ian G. Hansen, Sau-Lai Lee, Jennifer Yuk-Yue Tong, Ho-Ying Fu Dec 2003

How Are Social Identities Linked To Self-Conception And Intergroup Orientation? The Moderating Effect Of Implicit Theories, Ying-Yi Hong, Gloria Chan, Chi-Yue Chiu, Rosanna Y. M. Wong, Ian G. Hansen, Sau-Lai Lee, Jennifer Yuk-Yue Tong, Ho-Ying Fu

Research Collection School of Social Sciences

Social identity approaches assume that social identification affects both self-conception and intergroup orientation. The authors contend that such social identification effects are accentuated when people hold a fixed view of human character and attribute immutable dispositions to social groups. To these individuals, social identities are immutable, concrete entities capable of guiding self-conception and intergroup orientation. Social identification effects are attenuated when people hold a malleable view of human character and thus do not view social identities as fixed, concrete entities. The authors tested and found support for this contention in three studies that were conducted in the context of the …

A Robust Dissolve Detector By Support Vector Machine, Chong-Wah Ngo Nov 2003

A Robust Dissolve Detector By Support Vector Machine, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

In this paper, we propose a novel approach for the robust detection and classification of dissolve sequences in videos. Our approach is based on the multi-resolution representation of temporal slices extracted from 3D image volume. At the low-resolution (LR) scale, the problem of dissolve detection is reduced as cut transition detection. At the highresolution (HR) space, Gabor wavelet features are computed for regions that surround the cuts located at LR scale. The computed features are then input to support vector machines for pattern classification. Encouraging results have been obtained through experiments.

Content-Aware Authentication Of Motion Jpeg2000 Stream In Lossy Networks, Yongdong Wu, Robert H. Deng Nov 2003

Content-Aware Authentication Of Motion Jpeg2000 Stream In Lossy Networks, Yongdong Wu, Robert H. Deng

Research Collection School Of Computing and Information Systems

Stream authentication schemes (SAS) aim to achieve effective authentication of multicast streams over lossy networks. Almost all the existing SASs is designed for stream data integrity protection only. In this paper, we argue that content integrity protection is more important than data integrity to human users. We present a content-aware SAS in motion JPEG2000 streaming. In our scheme, a chunk of JPEG2000 codestreams is encapsulated into a block of packets using multiple description coding (MDC). Our MDC exploits the inherent structure of motion JPEG2000 codestreams and is used to preserve the semanteme/content of the stream over lossy networks. To achieve …

Pricing And Qos Of Information Services In A Competitive Market, Zhen Liu, Laura Wynter, Cathy Xia Nov 2003

Pricing And Qos Of Information Services In A Competitive Market, Zhen Liu, Laura Wynter, Cathy Xia

Research Collection School Of Computing and Information Systems

Design of e-commerce services that are competitive in a quickly responding market requires the analyses of prices and price structures. We develop a general model of an e-commerce market that allows us to analyze optimal price structures, both flat and usage-based. Based on the price structure of a major web hosting provider, we consider single-tier and two-tier (burst-rate) pricing, and our result suggests that the more complex two-tier structure may not be worth the marketing effort, as the firm's equilibrium profits will not increase through the use of this structure. An essential feature of our approach is that we model …

Web Unit Mining: Finding And Classifying Subgraphs Of Web Pages, Aixin Sun, Ee Peng Lim Nov 2003

Web Unit Mining: Finding And Classifying Subgraphs Of Web Pages, Aixin Sun, Ee Peng Lim

Research Collection School Of Computing and Information Systems

In web classification, most researchers assume that the objects to classify are individual web pages from one or more web sites. In practice, the assumption is too restrictive since a web page itself may not always correspond to a concept instance of some semantic concept (or category) given to the classification task. In this paper, we want to relax this assumption and allow a concept instance to be represented by a subgraph of web pages or a set of web pages. We identify several new issues to be addressed when the assumption is removed, and formulate the web unit mining …

Aa Flexible And Scalable Authentication Scheme For Jpeg 2000 Image Codestreams, Cheng Peng, Robert H. Deng, Yongdong Wu, Weizhong Shao

Research Collection School Of Computing and Information Systems

JPEG2000 is an emerging standard for still image compression and is becoming the solution of choice for many digital imaging fields and applications. An important aspect of JPEG2000 is its "compress once, decompress many ways" property [1], i. e., it allows extraction of various sub-images (e.g., images with various resolutions, pixel fidelities, tiles and components) all from a single compressed image codestream. In this paper, we present a flexible and scalable authentication scheme for JPEG2000 images based on the Merkle hash tree and digital signature. Our scheme is fully compatible with JPEG2000 and possesses a "sign once, verify many ways" …

Task Allocation Via Multi-Agent Coalition Formation: Taxonomy, Algorithms And Complexity, Hoong Chuin Lau, L. Zhang Nov 2003

Task Allocation Via Multi-Agent Coalition Formation: Taxonomy, Algorithms And Complexity, Hoong Chuin Lau, L. Zhang

Research Collection School Of Computing and Information Systems

Coalition formation has become a key topic in multiagent research. In this paper, we propose a preliminary classification for the coalition formation problem based on three driving factors (demands, resources and profit objectives). We divide our analysis into 5 cases. For each case, we present algorithms and complexity results. We anticipate that with future research, this classification can be extended in similar fashion to the comprehensive classification for the job scheduling problem.
