Abstract

Enterprises grapple with the significant challenge of managing proprietary unstructured data, hindering efficient information retrieval. This has led to the emergence of AI-driven information retrieval solutions, designed to adeptly extract relevant insights to address employee inquiries. These solutions often leverage pre-trained embedding models and generative models as foundational components. While pre-trained embeddings may exhibit proximity or disparity based on their original training objectives, they might not fully align with the unique characteristics of enterprise-specific data, leading to suboptimal alignment with the retrieval goals of enterprise environments. In this paper, we propose a methodology to fine-tune pre-trained embedding models specifically for enterprise environments. By adapting the embeddings to better suit the retrieval tasks prevalent in enterprises, we aim to enhance the performance of information retrieval solutions. We discuss the process of fine-tuning, its effect on retrieval accuracy, and the potential benefits for enterprise information management. Our findings demonstrate the efficacy of fine-tuned embedding models in improving the precision and relevance of search results in enterprise settings.

Abstract

Image steganography camouflages secret messages in images by tampering image contents. There is a natural desire for hiding maximum secret information with the least possible distortions in the host image. This requires an algorithm that intelligently optimizes the capacity keeping the required imperceptibility of the image. This paper presents an image steganography scheme that preserves an adaptively chosen block of dominant coefficients from each Discrete Cosine Transform coefficients, whereas the rest of the coefficients are replaced with normalized secret image pixel values. Secret image pixel value are normalized in an adaptively chosen range. Embedding such kind of normalized data in adaptively chosen non-square L- shaped blocks utilize maximum embedding space available in each block that consequently results in maximizing payload capacity, while maintaining the image quality. This scheme achieved payload capacity up to 21.5 bit per pixel (bpp), while maintaining image quality of 38.24 dB peak signal to noise ratio., Comment: 9 pages

29. Social entrepreneurship : an exploratory study of conception, business models and challenges in the UK

Author

Khan, Wasim Muhammad

Abstract

Social enterprises, a tangible outcome of social entrepreneurships, holds an immense potential to improve human afflictions and transform societies by uniting social entrepreneur’s passion for social change with fully functioning business models. Social enterprises are discerned from business enterprises due to their primary social mission, and from traditional non-profit organisations due to their implementation of commercial activities. However, there is still a lack of comprehensive understanding of various business models used by social enterprises and how they can be successfully managed to achieve their full potential. This research thus resolves three major enquiries concerning, identifying the determining factors in the conception of social enterprises, exploring the types of business models they employ and most importantly, investigating the key challenges, social enterprises encounter due to their unique structure. To address these research questions, this study adopted a qualitative research methodology to analyse eleven social enterprises in the UK, through in-depth semi structured interviews, ample observations, and archival research. Adopting a case study, research strategy and with close reference to existing literature, the empirical findings of research identified seven key determinants influencing the conception of social enterprise, concentrated to three major factor groups of personal factors, external factors, and internal factors. The empirical findings of this study further extend, by successfully identifying a conclusive typology of seven distinct self -sustainable business models by proposing a theoretical and contextual generalization of social enterprise business models. In terms of the key challenges, this study identifies seven key challenges that social enterprises face in their internal and external business environments, the most significant of which are: Difficulty in obtaining funds, Financial Sustainability, Maintaining a balance between social and financial goals, and Lack of recognition and policy framework. The empirical findings of this research offer theoretical and practical contributions, to the field of social entrepreneurship, social enterprise business models, and social bricolage literatures. This study also has implication for the practitioners by providing future social entrepreneurs with a set of core determinants that are mandatory for the initial development of their social enterprises. Careful consideration of these factors during the conception of social enterprises will provide a solid foundation to social entrepreneurs, upon which diverse forms of complex and mixed social business models can be developed. Moreover, Social entrepreneurs, managers and strategists may use the identified business model concepts in this study to both appraise existing and creatively design new business models.
