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

A comprehensive review of the genetics of juvenile idiopathic arthritis

Juvenile idiopathic arthritis (JIA) is the most common chronic arthropathy of childhood which is believed to be influenced by both genetic and environmental factors. The progress in identifying genes underlying JIA susceptibility using candidate gene association studies has been slow. Several associations between JIA and variants in the genes encoding the human leukocyte antigens (HLA) have been confirmed and replicated in independent cohorts. However it is clear that genetic variants outside the HLA also influence susceptibility to JIA. While a large number of non-HLA candidate genes have been tested for associations, only a handful of reported associations such as PTPN22 have been validated. In this review we discuss the principles behind genetic studies of complex traits like JIA, and comprehensively catalogue non-HLA candidate-gene association studies performed in JIA to date and review several validated associations. Most candidate gene studies are underpowered and do not detect associations, and those that do are often not replicated. We also discuss the principles behind genome-wide association studies and discuss possible implications for identifying genes underlying JIA. Finally we discuss several genetic variants underlying multiple clinically distinct autoimmune phenotypes

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

The marketing firm and co‐creation: The case of co‐creation by LEGO

This article discusses the marketer and customer co‐creation process within the context of bilateral contingencies. Bilateral contingencies occur when the marketers' behavior is reinforced (and/or punished) by the customers' behavior, whereas the behavior of the customers is reinforced (and/or punished) by the marketers' actions. Using the example of the LEGO community, we discuss how the marketers in the organization can respond to behaviors resulting from co‐creational customer– customer exchanges. This paper fills the knowledge gap by presenting a behavior analysis framework (theory of the marketing firm) for the empirical measurement of the co‐creation process.The marketing firm and co‐creation: The case of co‐creation by LEGOacceptedVersio

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.
