Meaning-focused and Quantum-inspired Information Retrieval

In recent years, quantum-based methods have promisingly integrated the traditional procedures in information retrieval (IR) and natural language processing (NLP). Inspired by our research on the identification and application of quantum structures in cognition, more specifically our work on the representation of concepts and their combinations, we put forward a 'quantum meaning based' framework for structured query retrieval in text corpora and standardized testing corpora. This scheme for IR rests on considering as basic notions, (i) 'entities of meaning', e.g., concepts and their combinations and (ii) traces of such entities of meaning, which is how documents are considered in this approach. The meaning content of these 'entities of meaning' is reconstructed by solving an 'inverse problem' in the quantum formalism, consisting of reconstructing the full states of the entities of meaning from their collapsed states identified as traces in relevant documents. The advantages with respect to traditional approaches, such as Latent Semantic Analysis (LSA), are discussed by means of concrete examples.Comment: 11 page

Dive Tourism and the Entrepreneurial Process in the Perhentian Islands, Malaysia

Dive tourism is a high growth, niche sector for island and coastal developing nations and is propelled predominantly by local tourism entrepreneurs and small businesses. This chapter examines dive tourism in peninsula Malaysia and particularly the factors influencing the entrepreneurial process. Much research on tourism entrepreneurs is derived from analysing business in the developed world, and has focused on the individual, not the process. Significantly less research exists for middle income and less developed countries despite the critical role tourism plays in national development planning. Similarly, a significant amount of dive tourism research has emerged from the science disciplines, but less so has originated from the social science community. This chapter contributes primarily to the initial knowledge gap by drawing upon extensive fieldwork interviews in the Perhentian islands. The findings broadly reveal dive tourism as a low cost industry that is transforming into a strategically competitive one. A more nuanced analysis reveals that the factors influencing the dive tourism entrepreneurial process are embedded within the social and historical context of Malaysia

Opening the box: Tourism planning and development in Myanmar: capitalism, communities and change

Myanmar (formerly Burma) is emerging from almost six decades of international isolation into a period of rapid economic growth. Following moves towards increasing democratisation since 2011, Myanmar’s tourism industry has been propelled from “tourism pariah” to rising “tourism star” and is experiencing an extraordinary growth in tourism arrivals with associated revenues and investment. The unique rapidity of Myanmar’s recent transition enables an examination of how contemporary forces of globalisation and neoliberalism determine the direction and mode of tourism development from its beginnings. We show how tourism is perceived by the national government as an engine for rural development, conservation and livelihood creation for poor and rural communities. We then demonstrate how this is re-shaped by a globalised tourism industry into a socially and economically exclusive model which capitalises upon weak governance and disempowered local stakeholders. We conclude with observations which may point towards a more sustainable and responsible tourism industry

The political economy of international dive tourism

Using a critical political economy approach and the concept of labour precarity, the international dive tourism industry in Sabah, Malaysia and its workers’ vulnerabilities are interrogated. Fieldwork data highlights dive tourism’s socio-economic impacts and the precarity of labour within the international tourism sector and also critiques it as a development strategy for a peripheral region. The paper challenges the optimistic views of labour precarity found in the existing political economy literature. Rather than identifying labour empowerment, evidence demonstrates significant worker vulnerability, uncertainty, and contingency - especially among ethnic minorities - resulting from Malaysia’s state-led rentier econom

Residual Strength Predictions with Crack Buckling

Fracture tests were conducted on middle crack tension, M(T), and compact tension, C(T), specimens of varying widths, constructed from 0.063 inch thick sheets of 2024-T3 aluminum alloy. Guide plates were used to restrict out-of-plane displacements in about half of the tests. Analyses using the three-dimensional, elastic-plastic finite element code WARP3D simulated the tests with and without guide plates using a critical CTOA fracture criterion. The experimental results indicate that crack buckling reduced the failure loads by up to 40%. Using a critical CTOA value of 5.5 deg., the WARP3D analyses predicted the failure loads for the tests with guide plates within +/- 10% of the experimentally measured values. For the M(T) tests without guide plates, the WARP3D analyses predicted the failure loads for the 12 and 24 inch tests within 10%, while over predicting the failure loads for the 40 inch wide tests by about 20%
