Fast and power efficient 16×16 Array of Array multiplier using Vedic Multiplication

This paper discusses about "Array of Array" multiplier which is a derivative of Braun Array Multiplier. Braun array are much suitable for VLSI implementation because of its less space complexity though it shows larger time complexity, on the other hand tree multipliers have time complexity of O(log n) but are less suitable for VLSI implementation since, being less regular; they require larger total routing length, which leads to performance degradation; simply put, they show higher space complexity. The main advantage of "Array of Array" multipliers is its inherent ability to reduce both time and space complexity [7] [8] with intermediate relative performance [7]. In this paper a 16×16 unsigned 'Array of Array' multiplier circuit is designed with hierarchical structuring, it has been optimized using Vedic Multiplication Sutra (Algorithm) "Urdhva Triyagbhyam" [1][6] and Karatsuba-Ofman algorithm[2]. The proposed algorithm is useful for math coprocessors in the field of computers. Algorithm is implemented on SPARTAN-3E FPGA (Field Programmable Gate Array). The proposed multiplier implementation shows large reduction in average power dissipation and in time delay as compared to Booth encoded radix-4 multiplier

Measuring consumers' engagement with brand-related social-media content: development and validation of a scale that identifies levels of social-media engagement with brands

The main purpose of this study is to develop a scale to measure consumer's engagement with social media brand-related content. The reported scale (CESBC) comprises three dimensions: consumption, contribution, and creation. Qualitative techniques were used to generate an initial pool of items that capture different levels of consumer engagement with social media brand-related content. Quantitative data from a consumer survey (=2252) was then collected in two phases to calibrate and validate the ensuing scale. Results confirmed the structure and psychometric properties of the CESBC. As expected, each subscale is significantly correlated with nomological network constructs, i.e., brand equity and brand attitudes

When grassroots innovation movements encounter mainstream institutions: implications for models of inclusive innovation

Grassroots innovation movements (GIMs) can be regarded as initiators or advocates of alternative pathways of innovation. Sometimes these movements engage with more established science, technology and innovation (STI) institutions and development agencies in pursuit of their goals. In this paper, we argue that an important aspect to encounters between GIMs and mainstream STI institutions is the negotiation of different framings of grassroots innovation and development of policy models for inclusive innovation. These encounters can result in two different modes of engagement by GIMs; what we call insertion and mobilization. We illustrate and discuss these interrelated notions of framings and modes of engagement by drawing on three case studies of GIMs: the Social Technologies Network in Brazil, and the Honey Bee Network and People's Science Movements in India. The cases highlight that inclusion in the context of GIMs is not an unproblematic, smooth endeavour, and involves diverse interpretations and framings, which shape what and who gets included or excluded. Within the context of increasing policy interest, the analysis of encounters between GIMs and STI institutions can offer important lessons for the design of models of inclusive innovation and development

Argentina — Import Measures: How a Porsche is Worth Peanuts

The dispute Argentina-Measures Affecting the Importation of Goods concerns a series of measures imposed by Argentine authorities on economic operators as a condition for obtaining import licenses. These measures were introduced with the goal of advancing the Argentine government’s stated policies of re-industrialization, import substitution, and elimination of trade balance deficits. From a legal point of view, the least interesting feature of the dispute was the substantive compatibility of these measures with Article XI:1 GATT as they clearly constituted import restrictions. Identifying and classifying the measures involved, however, proved more challenging: based on vague policy guidelines, devoid of any legal basis, and consisting largely of wholly discretionary ad hoc action by the authorities, clouded in confidential obscurity, the measures escaped familiar categories and distinctions of WTO law. From an economic perspective, although Argentina’s measures appear to have had no impact on its overall imports, they imposed large costs on foreign companies, as well as on Argentine importers and consumers.

Financialization directing strategy

Original article can be found at: http://www.sciencedirect.com/science/journal/01559982 Copyright Elsevier Ltd. DOI: 10.1016/j.accfor.2008.08.001This paper constructs an account of how financialization is directing strategy in the S&P 500. Financialization describes how changes in US accounting regulations require firms to account for the market value of capital market transactions where corporate strategy is not simply concerned with delivering value creation but also reacting to value absorption in an era of shareholder value. Financialization is directing strategy and arbitrage to modify stakeholder financial settlements where an increased share of income is extracted as surplus cash and more of this cash from operations is being distributed to shareholders. Share buy-backs account for a substantial increase in the share of corporate cash distributed to shareholders in the S&P 500 which, we argue, reflects a strategic process of value creation and value absorption.Peer reviewe

Agri-food business: Global challenges â Innovative solutions

The rise of a western-style middle class in many successful emerging economies like China currently is inducing deep structural changes on agricultural world markets and within the global agri-food business. As a result of both higher incomes and concerns over product safety and quality the global demand for high-quality and safe food products is increasing significantly. In order to meet the new required quality, globally minimum quality standards are rising and private standards emerging. All over the world these developments cause adjustments at the enterprise, chain and market levels. At the same time, the tremendously increasing demand for renewable energy has led to the emergence of a highly promising market for biomass production. This has far-reaching consequences for resource allocation in the agri-food business, for the environment, for the poor in developing countries and for agricultural policy reforms. The challenges increase with ongoing liberalisation, globalisation and standardisation, all of which change trade patterns for agricultural and food commodities, and influence production costs and commodity prices. The objective of the IAMO Forum is to show opportunities as well as risks for all participants of the food economy in the ongoing globalisation process: for small peasants in developing countries, farmers in Europe and globally active food enterprises and retailers. The success of enterprises depends on the ability to find innovative solutions with regard to the organisation of enterprises, chains, and markets, as well as future policy design. Concerning bio-energy strategies has to be identified to combat global warming most efficiently and concurrently attenuate the competition between "tank and table" on farmland. IAMO Forum 2008, as well as this book, would not have been possible without the engagement of many people and institutions. We thank the authors of the papers, as well as the referees. Furthermore we are highly indebted to MARLIES LOHR, NADINE GIEMSA and RONNY RECKE who in an outstanding way contributed to the organisation of the Forum.

Collaborative research and development (R&D) for climate technology transfer and uptake in developing countries: Towards a needs driven approach

While international cooperation to facilitate the transfer and uptake of climate technologies in developing countries is an ongoing part of climate policy conversations, international collaborative R&D has received comparatively little attention. Collaborative R&D, however, could be a potentially important contributor to facilitating the transfer and uptake of climate technologies in developing countries. But the complexities of international collaborative R&D options and their distributional consequences have been given little attention to date. This paper develops a systematic approach to informing future empirical research and policy analysis on this topic. Building on insights from relevant literature and analysis of empirical data based on a sample of existing international climate technology R&D initiatives, three contributions are made. First, the paper analyses the coverage of existing collaborative R&D efforts in relation to climate technologies, highlighting some important concerns, such as a lack of coverage of lower-income countries or adaptation technologies. Second, it provides a starting point for further systematic research and policy thinking via the development of a taxonomic approach for analysing collaborative designs. Finally, it matches characteristics of R&D collaborations against developing countries’ climate technology needs to provide policymakers with guidance on how to Configure R&D collaborations to meet these needs

The Effects of Culture and Structure on Strategic Flexibility During Business Model Innovation

This study uses responses from 107 multinational firms to reveal CEO perceptions of the drivers of strategic flexibility during business model innovation. While the positive effect of creative culture is confirmed, partner reliance reduces strategic flexibility during business model innovation. Further, structural change is disaggregated into efforts that either focus managerial attention on core activities or reconfigure existing activities. CEOs perceive that structural flexibility requires structural simplification while retaining control of non-core functions. We find that the relative magnitude of business model innovation effort moderates the effect of reconfiguration on strategic flexibility. The implications for theories of organizational design and dynamic capabilities are discussed
