Institutional Entrepreneurship and Acquiring Legitimacy of Social Commerce Platform
Research on social commerce has ignored the process and mechanism of institutional entrepreneurship. Based on the institutional theory, we use qualitative research methods to study the process of institutional entrepreneurship of social commerce. This paper also analyzes the legitimacy acquisition process of social commerce from the perspective of institutional contradiction and institutional logic. We found that, firstly, institutional contradictions existing in traditional e-commerce organization field are the fundamental motivation for institutional entrepreneurship of social commerce platform. Secondly, social commerce entrepreneur proposed new institutional logics which are the solutions according to the institutional contradictions existing in traditional e-commerce organization field. Thirdly, because of the new institutional logics proposed by institutional entrepreneur, social commerce platform acquired cognitive legitimacy and normative legitimacy. Finally, the factors of organizational field influence the whole process of institutional entrepreneurship of social commerce
An Ontological Approach to Representing the Product Life Cycle
The ability to access and share data is key to optimizing and streamlining any industrial production process. Unfortunately, the manufacturing industry is stymied by a lack of interoperability among the systems by which data are produced and managed, and this is true both within and across organizations. In this paper, we describe our work to address this problem through the creation of a suite of modular ontologies representing the product life cycle and its successive phases, from design to end of life. We call this suite the Product Life Cycle (PLC) Ontologies. The suite extends proximately from The Common Core Ontologies (CCO) used widely in defense and intelligence circles, and ultimately from the Basic Formal Ontology (BFO), which serves as top level ontology for the CCO and for some 300 further ontologies. The PLC Ontologies were developed together, but they have been factored to cover particular domains such as design, manufacturing processes, and tools. We argue that these ontologies, when used together with standard public domain alignment and browsing tools created within the context of the Semantic Web, may offer a low-cost approach to solving increasingly costly problems of data management in the manufacturing industry
Feasibility Study of Tractor-Test Vehicle Technique for Practical Structural Condition Assessment of Beam-Like Bridge Deck
The tractor-test vehicle technique of non-destructive testing for indirect measurement of the modal properties of a bridge deck is revisited in this paper with several improvements for possible practical application to the structural condition assessment of a beam-like bridge deck. The effect of damping of the vehicle-bridge system is considered and the modal properties from only the first vibration mode of the structure will be used for a quick and simple assessment. The two test vehicles are designed to have the same modal frequency and damping ratio but with parameters in the follower No.2 test vehicle proportional to those in the follower No.1 test vehicle. This effectively removes the effect of road surface roughness in the response of an equivalent vehicle such that the error in the subsequent condition assessment is reduced. Through data collected on-sitetransmitted to theremote computer platform, a simple technique based on the moment-curvature relationship acceptable to practical engineers is adopted for the condition assessment with improvements in the estimation of the element bending stiffness of the deck. Scenarios with different damping, vehicle speed, road surface roughness, and local damages in the bridge structure are studied with or without temperature effect in the measurement. Through numerical simulations and field tests, the tractor-test vehicle technique of non-destructive testing with the proposed modifications and improvements has been demonstrated to give consistently accurate estimates of the element bending stiffness of the bridge deck but with a small error close to the end of the deck
MixPoet: Diverse Poetry Generation via Learning Controllable Mixed Latent Space
As an essential step towards computer creativity, automatic poetry generation
has gained increasing attention these years. Though recent neural models make
prominent progress in some criteria of poetry quality, generated poems still
suffer from the problem of poor diversity. Related literature researches show
that different factors, such as life experience, historical background, etc.,
would influence composition styles of poets, which considerably contributes to
the high diversity of human-authored poetry. Inspired by this, we propose
MixPoet, a novel model that absorbs multiple factors to create various styles
and promote diversity. Based on a semi-supervised variational autoencoder, our
model disentangles the latent space into some subspaces, with each conditioned
on one influence factor by adversarial training. In this way, the model learns
a controllable latent variable to capture and mix generalized factor-related
properties. Different factor mixtures lead to diverse styles and hence further
differentiate generated poems from each other. Experiment results on Chinese
poetry demonstrate that MixPoet improves both diversity and quality against
three state-of-the-art models.Comment: 8 pages, 5 figures, published in AAAI 202
