De-westernizing creative labour studies: The informality of creative work from an ex-centric perspective
Creative labour studies focus almost exclusively on Euro-American metropolitan ‘creative hubs’ and hence the creative worker they theorize is typically white, middle-class, urban and overwhelmingly male. This article outlines the contours of a de-Westernizing project in creative labour studies while introducing a special journal issue that examines the lived dynamics of creative work outside the West. The article advocates an ‘ex-centric perspective’ on creative work. An ex-centric perspective does not merely aim at multiplying non-West empirical case studies. Rather, it aims at destabilizing, decentring and provincializing the taken-for-grantedness of some entrenched notions in creative labour studies such as informality and precarity. An ex-centric perspective, we contend, offers a potential challenge to many of the claims about creative work that have taken on the status of general truths and universal principles in spite of them being generated from limited empirical evidence gleaned from research sites situated almost exclusively in the creative hubs of Euro-America
Multimodal Content Analysis for Effective Advertisements on YouTube
The rapid advances in e-commerce and Web 2.0 technologies have greatly
increased the impact of commercial advertisements on the general public. As a
key enabling technology, a multitude of recommender systems exists which
analyzes user features and browsing patterns to recommend appealing
advertisements to users. In this work, we seek to study the characteristics or
attributes that characterize an effective advertisement and recommend a useful
set of features to aid the designing and production processes of commercial
advertisements. We analyze the temporal patterns from multimedia content of
advertisement videos including auditory, visual and textual components, and
study their individual roles and synergies in the success of an advertisement.
The objective of this work is then to measure the effectiveness of an
advertisement, and to recommend a useful set of features to advertisement
designers to make it more successful and approachable to users. Our proposed
framework employs the signal processing technique of cross modality feature
learning where data streams from different components are employed to train
separate neural network models and are then fused together to learn a shared
representation. Subsequently, a neural network model trained on this joint
feature embedding representation is utilized as a classifier to predict
advertisement effectiveness. We validate our approach using subjective ratings
from a dedicated user study, the sentiment strength of online viewer comments,
and a viewer opinion metric of the ratio of the Likes and Views received by
each advertisement from an online platform.Comment: 11 pages, 5 figures, ICDM 201
From governance to meta-governance in tourism?: Re-incorporating politics,interests and values in the analysis of tourism governance
Despite its theorization in the political and policy sciences in the early 1990s, the concept of metagovernance has gained relatively little recognition in tourism studies. Nevertheless, its significance in the political sciences and policy literature, especially as a result of the perceived failure of governance systems following the recent global financial crisis, has only served to reinforce its relevance. Metagovernance addresses some of the perceived failures of traditional governance approaches and associated interventions, and has enabled the understanding of central-state led regimes of shadowed hierarchical authorities and local-level micro-practices of social innovation and self-government. In contrast, tourism studies have tended to restrict study of the political dimension of tourism governance and the role of the state under the traditional parallelism between government and governance. Examination of how governance is itself governed enables a better understanding of the practices of planning and policy making affecting tourism and destinations. In particular, the applications of concepts of governance are inextricably linked to a given set of value assumptions which predetermine the range of its application. A short example of the application of the metagovernance paradigm is provided from the New Zealand context. It is concluded that governance mechanisms are not value-neutral and instead serve to highlight the allocation of power in a destination and the dominance of particular values and interests
Basic tasks of sentiment analysis
Subjectivity detection is the task of identifying objective and subjective
sentences. Objective sentences are those which do not exhibit any sentiment.
So, it is desired for a sentiment analysis engine to find and separate the
objective sentences for further analysis, e.g., polarity detection. In
subjective sentences, opinions can often be expressed on one or multiple
topics. Aspect extraction is a subtask of sentiment analysis that consists in
identifying opinion targets in opinionated text, i.e., in detecting the
specific aspects of a product or service the opinion holder is either praising
or complaining about
eWOM & Referrals in Social Network Services
If a few decades ago the development of the Internet was instrumental in the interconnection between markets, nowadays the services provided by Web 2.0, such as social network sites (SNS) are the cutting edge. A proof of this trend is the exponential growth of social network users. The main objective of this work is to explore the mechanisms that promote the transmission and reception (WOM and referrals) of online opinions, in the context of the
SNS, by buyers of travel services. The research includes some research lines: technology acceptance model (TAM), Social Identification Theory and Word-of-Mouth communication in virtual environment (eWOM). Based on these theories an explicative model has been proposed applying SEM analysis to a sample of SNS users’ of tourist service buyers. The results support the majority of the hypotheses and some relevant practical and theoretical
implications have been pointed out for tourist managers
