Sustaining social innovation enterprises through a design led innovation framework

Constant changes in the global economic environment require companies to revisit traditional assumptions about how businesses create and capture value (Teece, 2010). In recent years, management practice literature has focused largely on better understanding business models and business model innovation (Amit, Zott and Massa, 2010; Johnson, Christensen and Kagermann, 2008). Much has been written on the benefits of linking design and design thinking to organisational strategies and business transformation. However, very little has been researched and reported on regarding the impact of design led approaches to triple bottom-line opportunities such as, social innovation enterprise. In the context of this paper Design Led Innovation is defined as the tools and approaches which enable design thinking to be embedded as an element of cultural transformation within a business. Being Design Led requires a company to have a vision for top line growth founded on deep customer insights and expanded through customer and stakeholder engagements. The outcomes of this are then mapped to all aspects of the business, enabling the vision to be successfully implemented and achieved. It is the latter part of this definition where we believe Design Led Innovation has the greatest value in transforming social innovation enterprise into a sustainable business venture. However, we also acknowledge that enabling these firms to think strategically about their business model is difficult given the unique operational and funding challenges that often characterize many social enterprises. The purpose of this paper, therefore, is to pose the question, do sustainable innovation enterprise innovate their business model? And if so, how? It is the authors’ opinion that such enterprises only innovate at the product or system level without a complete understanding of the business model structure, which underpins the long term viability. However, in this paper we challenge this notion and explore if such firms can overcome their size and operational constraints to become sustainable enterprises using a design led approach. This is achieved through contextualizing business model innovation, briefly defining social innovation enterprise and profiling a new and emerging industry in Australia – Clean Technology. Future research challenges and opportunities are also presented.
Analysis of Financial Health of Steel Authority of India Limited

India’s economic growth is contingent upon the growth of the Indian steel industry. India’s GDP growth rate was 7.2% by 2011. The steel sector is contributing about 2% in India’s GDP. Consumption of steel is taken to be an indicator of economic development. India occupies a central position on the global steel map. Steel production in India has increased by a compounded annual growth rate (CAGR) of 8 percent over the period 2002-03 to 2006-07. But the financial progress of this sector is not satisfactory. Thus, the present paper is an attempt to review the financial performance of one of the most popular and renowned company in the field of steel sector. That is Steel Authority of India Limited (SAIL), one of the leading steel making company of the country. The study is purely based on secondary data. A period of five year from 2005-06 to 2009-10 has been selected for the study. The data have been tabulated, analyzed and interpreted with the help of various financial ratios and Multivariate Discriminate Analysis (MDA) as developed by Prof. Edward I. Altman (1968). It is observed from the analysis of various ratios that the profit earning capacity, liquidity position and long-term solvency position of SAIL is quite good during the study period and the level of bankruptcy position is also very low. Keywords: Financial Analysis, Ratio Analysis, Steel Industry, Multivariate Discriminate Analysis (MDA).
Informal interpreting in general practice: the migrant patient’s voice

ABSTRACT Objective: To explore the perspective of Turkish-Dutch general practitioner (GP) patients on informal interpreting from an integrated theory base, focusing on interpreters’ roles, trust and power. Design: Semi-structured in depth interviews were conducted with 21 first-generation Turkish-Dutch migrant patients who made use of informal interpreters to communicate with their GPs. An interview guide was designed based on the theoretical framework of interpreter’s roles, trust and power, covering questions about interpreters’ role, trust in informal/professional interpreters and power division in the medical consultation. The interviews were transcribed verbatim and analyzed according to the constant comparative method. Results: Besides providing linguistic translation, informal interpreters were expected to perform the roles of advocates and caregivers of the patients. Informal interpreters were trusted more than professional interpreters, mainly for fidelity reasons, that is, because the patients assumed that informal interpreters would act in their best interests. Although informal interpreters were often perceived as the primary interlocutor, the patients did not feel dominated by them, but rather empowered by their presence. Conclusion: Our findings indicate a connection between the role of the advocate, the fidelity dimension of trust and the perceived empowerment of the patients. By linking interpreters’ role to trust and power, this study contributes to theory building in the field of informal interpreting, which is needed to design evidence-based interventions to improve health care delivery to patients with insufficient language ability and thus to advance health care delivery to migrant patients, which is currently lagging behind.
Interdependence and Adaptability: Organizational Learning and the Long - Term Effect of Integration

A growing body of research documents the role that organizational learning plays in improving firm performance over time. To date, however, this literature has given limited attention to the effect that the internal structure of the firm can have on generating differences in these learning rates. This paper focuses on the degree to which interdependence--and in particular one structural characteristic that generates interdependence, vertical integration--affects organizational learning. Firms face a trade-off. In stable environments, vertically integrating severely limits the organization's ability to learn by doing because boundedly rational managers find the optimization of operations difficult when making highly interdependent choices. As the volatility of the environment increases though, integration can facilitate learning-by-doing by buffering activities within the firm from instability in the external environment. Thus, firms with a high degree of interdependence suffer less in these environments. Tests of these hypotheses on the growth and exit rates of computer workstation manufacturers support this thesis.
Indirect position and speed sensing for PMSM sensorless control

This paper present a position and speed estimation algorithm based on measurement of phase currents and voltages and a pre-knowledge of the machine model. The aim is to elaborate an accurate estimator in accordance with some specifications, especially the ability to cancel any initial position error and robustness toward a dc-disturbance measured within the electric measurements. In earlier work, an old version of this method was investigated for open-loop position and speed estimation of permanent magnet motor. The present work provides complete description and Real-Time implementation of the method incorporated into sensorless vector control.
The organisation and economic geographies of marketing and public relations businesses in the West Midlands

This thesis examines the marketing and public relations industries in a sub-region of the West Midlands GOR, which stretches from Birmingham to the country towns and villages of Warwickshire and Worcestershire. The area is characterised as a hotspot for particular knowledge intensive businesses and entrepreneurial activity. By undertaking a whole sector analysis the formation and embeddedness of firms within the tight-knit marketing and PR community are elucidated. Examining acts of entrepreneurship and firm formation highlight the importance of different factors in the individual decision-making processes of new enterprise start-ups. This produces a plethora of small business organisations that service clients at distance using information and communication technologies (ICT), coupled with the concomitant industry expertise and contacts. There is a stretching of networks, enabled by ICT, whereby pre-existing relationships continue to be exploited. Consequently all firms, including home-based businesses and micro firms are easily established and represent a plethora of business models engaging in networks at a range of spatial scales. This thesis argues that BPS sectors are characterised by a plurality of business organisations which are crucial for the continual development of the sectors. Integral to this are ICT which facilitate a set of extensively and intensively flexible business organisations.
Option Backdating: Market Overreaction and Management Motives

Prior studies on option backdating have focused exclusively on the initial backdating investigation announcements. We extend the analyses to consider the outcomes of the investigation as well. By examining the market responses both to the initial investigation announcement and to the investigation outcome, we provide an evidence that the market may have overreacted to the initial investigation announcement. Our results also show that the media bias in covering more bad than good news may have contributed to the overreaction. Finally, we re-examine the issue of management motives, focusing on firms which were found to be guilty of intentional backdating. No prior study has addressed the motive issues with the sample of “true” backdators before.
Genome‐wide mapping of ZNF652 promoter binding sites in breast cancer cells

A significant proportion of transcription factors encoded by the human genome are classical C2H2 zinc finger proteins that regulate gene expression by directly interacting with their cognate DNA binding motifs. We previously showed that one such C2H2 zinc finger DNA binding protein, ZNF652 (zinc finger protein 652), specifically and functionally interacts with CBFA2T3 to repress transcription of genes involved in breast oncogenesis. To identify potential targets by which ZNF652 exerts its putative tumour suppressive function, its promoter‐specific cistrome was mapped by ChIP‐chip. De novo motif scanning of the ZNF652 binding sites identified a novel ZNF652 recognition motif that closely resembles the previously characterised in vitro binding site, being a 10 nucleotide core of that 13 nucleotide sequence. Genes with ZNF652 binding sites function in diverse cellular pathways, and many are involved in cancer development and progression. Characterisation of the in vivo ZNF652 DNA binding motif and identification of potential ZNF652 target genes are key steps towards elucidating the function(s) of this transcription factor in the normal and malignant breast cell.

High Salt-induced Conversion of Escherichia coliGroEL into a Fully Functional Thermophilic Chaperonin*

The GroE chaperonin system can adapt to and function at various environmental folding conditions. To examine chaperonin-assisted protein folding at high salt concentrations, we characterized Escherichia coli GroE chaperonin activity in 1.2 m ammonium sulfate. Our data are consistent with GroEL undergoing a conformational change at this salt concentration, characterized by elevated ATPase activity and increased exposure of hydrophobic surface, as indicated by increased binding of the fluorophore bis-(5,5′)-8-anilino-1-naphthalene sulfonic acid to the chaperonin. The presence of the salt results in increased substrate stringency and dependence on the full GroE system for release and productive folding of substrate proteins. Surprisingly, GroEL is fully functional as a thermophilic chaperonin in high concentrations of ammonium sulfate and is stable at temperatures up to 75 °C. At these extreme conditions, GroEL can suppress aggregation and mediate refolding of non-native proteins.
A Channel Statistic Based Power Allocation in a Butterfly Wireless Network with Network Coding

An amplified-and-forward network coded protocol (ANCP) is proved to achieve excellent network performance [6]. In this paper, we first drive the closed-form expression of the system outage probability in the high SNR regime, based on ANCP protocol in a classical butterfly wireless network. However the complex expression is a bottleneck of developing power allocation. Then we approximate the expression with a simplified version and propose power allocation strategies with a closed form, only requiring statistical channel state information (CSI). Finally, it is shown that the closed-form expression almost overlap the curve of the system outage probability by Monte Carlo simulation in the high SNR regime and the simplified version is very close to the simulation curve. Moreover, it is validated that the proposed power allocation strategies achieve a large signal-noise ratio (SNR) gain over the system without power allocation strategies.
Social media policy in South Africa

Social media use is a growing trend worldwide. It is viewed as a revolution in electronic communications and an effective business marketing tool. Despite the business benefits, social media is viewed as a risk within organisations. This study examines the perceptions of CAEs (Chief Audit Executives) on the state of development and implementation of social media policies in companies in South Africa. The study reveals that even though social media is perceived to be a risk, most of the organisations surveyed have not implemented a social media policy. This might be because social media policies are not perceived to be effective, or because social media is classified as a lower priority risk within the organisations. The study reveals that social media is not part of the internal audit universe in most organisations, supporting two perceptions: that it might be viewed as a lesser risk; and that the organisations and internal audit functions have not yet fully understood the nature and potential negative impact social media usage can have on business.
Revision of the linkage map of Bacillus subtilis 168: indications for circularity of the chromosome

A revision of the linkage map of the Bacillus subtilis 168 chromosome has been undertaken with the use of the generalized transducing phage PBS1. The mapping of four new markers (narB1, mtlB1, aroI906, and tre-12) has allowed a determination of the relative orientation of the purB-dal segment and its linkage with the lin markers. The chromosomal segment comprised between the sacQ36 and gtaA12 markers has been linked with the narA1, ctrA1, and sacA321 markers. The recA1 marker has been mapped relative to the thyA and citB17 markers. Indications of linkage have been found between the tre-12 and catA markers and the aroG932 and sacQ36 markers. According to these results, a circular genetic map of the chromosome of B. subtilis 168 is presented. Taken together, the transduction data and the order of marker replication determined by Harford in the accompanying paper support strongly the hypothesis of a symmetrical and fully bidirectional mode of replication for the B. subtilis 168 chromosome.
A comparative study of tourist attitudes towards culinary tourism in Spain and Slovenia

Purpose – The purpose of this paper is to determine the role of gastronomy as a destination attraction, tourists’ perception of culinary tourism, its influence on satisfaction with the trip, and the economic value tourist’s attach to the opportunity to try traditional cuisine. The paper also examines possible sociocultural differences between different tourist segments according to how they rate gastronomy in their motivations for travel. Design/methodology/approach – Data were collected by means of 392 questionnaires distributed in Ljubjlana (Slovenia) and Cordoba (Spain). Various bivariate and multivariate statistical techniques are used to perform a comprehensive econometric study. Findings – Tourists exhibit greater interest in gastronomy as a travel motivation in the Spanish city, where they value aspects related to this activity more positively. However, the willingness to pay more to try traditional food is similar in both cities. No sociodemographic differences were found between the segments rega.
A REVIEW PAPER ON DESIGN AND SIMULATION OF UNIVERSAL ASYNCHRONOUS RECEIVER TRANSMITTER ON FIELD PROGRAMMABLE GATE ARRAY USING VHDL

Universal Asynchronous Receiver Transmitter (UART) is the use of the serial communication protocol, low velocity, short distance, low cost data exchange between computer and peripherals. Due to simultaneous transmission of data bits or multiple accesses, the system complexity increases, in parallel communication so, to alleviate this drawback, we uses serial communication. UART includes three modules which are received, the baud rate generator and transmitter. The UART design with Very High Description Language can be integrated into the Field Programmable Gate Array to achieve reliable, compact and stable data transmission. In the result and simulation part, this project will focus on check the receive data with error free & baud rate generation at different frequencies. The proposed work suggests application design using UART. All modules are designed using VHDL and implemented on Xilinx FPGA development board.
On quaternion based parameterization of orientation in computer vision and robotics

The problem of orientation parameterization for applications in computer vision and robotics is examined in detail herein. The necessary intuition and formulas are provided for direct practical use in any existing algorithm that seeks to minimize a cost function in an iterative fashion. Two distinct schemes of parameterization are analyzed: The first scheme concerns the traditional axis-angle approach, while the second employs stereographic projection from unit quaternion sphere to the 3D real projective space. Performance measurements are taken and a comparison is made between the two approaches. Results suggests that there exist several benefits in the use of stereographic projection that include rational expressions in the rotation matrix derivatives, improved accuracy, robustness to random starting points and accelerated convergence. © 2014 Kavala Institute of Technology.
An Empirical Study on Continuance Using Intention of Mobile Social Apps

User’s continuance intention is vital to the future of mobile social apps (i.e. applications) with rapid development and intensive competitions among their providers. We draw on the theory of flow experience and switching cost to build an integrated model to explain factors influencing users’ continuance using intention. Our model is tested by survey and Structural Equation Model (SEM) in the mobile social apps context of Wechat because of its popularity. The empirical results show that: Perceived enjoyment has significant influence on flow experience, and further positively affect users’ continuance using intention; Switching costs exert significant positive effect on continuance intention; Contrary to our hypothesis, time flexibility of mobile devices has no significant influence on users’ continuance using intention towards mobile social apps. With regard to the mediating effect of flow experience, we find that it exerts partially mediating effect between perceived enjoyment and continuance using intention and exert no mediating effect between mobile time flexibility and users’ continuance using intention towards mobile social apps.
A Graph Regularized Deep Neural Network for Unsupervised Image Representation Learning

Deep Auto-Encoder (DAE) has shown its promising power in high-level representation learning. From the perspective of manifold learning, we propose a graph regularized deep neural network (GR-DNN) to endue traditional DAEs with the ability of retaining local geometric structure. A deep-structured regularizer is formulated upon multi-layer perceptions to capture this structure. The robust and discriminative embedding space is learned to simultaneously preserve the high-level semantics and the geometric structure within local manifold tangent space. Theoretical analysis presents the close relationship between the proposed graph regularizer and the graph Laplacian regularizer in terms of the optimization objective. We also alleviate the growth of the network complexity by introducing the anchor-based bipartite graph, which guarantees the good scalability for large scale data. The experiments on four datasets show the comparable results of the proposed GR-DNN with the state-of-the-art methods.
Isolation and Characterization of Mobile Genetic Elements from Microbial Assemblages Obtained from the Field Research Center Site

Considerable knowledge has been gained from the intensive study of a relatively limited group of bacterial plasmids. Recent efforts have begun to focus on the characterization of, at the molecular level, plasmid populations and associated mobile genetic elements (e.g., transposons, integrons) occurring in a wider range of aquatic and terrestrial habitats. Surprisingly, however, little information is available regarding the incidence and distribution of mobile genetic elements extant in contaminated subsurface environments. Such studies will provide greater knowledge on the ecology of plasmids and their contributions to the genetic plasticity (and adaptation) of naturally occurring subsurface microbial communities. We requested soil cores from the DOE NABIR Field Research Center (FRC) located on the Oak Ridge Reservation. The cores, received in February 2003, were sampled from four areas on the Oak Ridge Site: Area 1, Area 2, Area 3 (representing contaminated subsurface locales) and the background reference sites. The average core length (24 in) was subdivided into three profiles and soil pH and moisture content were determined. Uranium concentration was also determined in bulk samples. Replicate aliquots were fixed for total cell counts and for bacterial isolation. Four different isolation media were used to culture aerobic and facultative microbes from these four more » study areas. Colony forming units ranged from a minimum of 100 per gram soil to a maximum of 10,000 irrespective of media composition used. The vast majority of cultured subsurface isolates were gram-positive isolates and plasmid characterization was conducted per methods routinely used in the Sobecky laboratory. The percentage of plasmid incidence ranged from 10% to 60% of all isolates tested. This frequency appears to be somewhat higher than the incidence of plasmids we have observed in other habitats and we are increasing the number of isolates screened to confirm this observation. We are also characterizing the plasmid populations at the molecular level. Isolates cultured from the background control site exhibited the lowest occurrence of plasmids (10%). Aliquots of samples were also used in enrichment assays to isolate metal resistant subsurface isolates. Samples were subjected to three different metals (chromium, mercury and cadmium) at two different concentrations and incubated following a conditioning period in which samples were amended with a carbon, nitrogen and phosphorus source. Isolates were plated on metal selection, purified to single isolates and plasmid content determined. « less
