Innovation and change in English teaching in the western provinces of China: the impact of overseas training

In this article we explore issues around the impact of continuing professional development (CPD) for secondary teachers of English offered by an overseas provider through the lens of participants from the Western provinces of China who completed courses at a UK university between 2003 and 2012. We start by offering an overview of English teaching in China. We then report two complementary studies of the same programme. The first aimed for breadth of understanding and involved the collection and analysis of interviews and focus groups discussions with former participants, their teaching colleagues and senior management, as well as classroom observation. The second aimed for depth and drew on data collected from a cohort of 38 teachers on one of the courses, using pre- and post-course surveys; focus group discussions at the end of the course with the whole cohort; and interviews with five of the participants both before they left the UK and again six months later. Evidence is presented for changes in teachers’ philosophies of education directly attributable to participation in the courses; for improved teacher competencies (linguistic, cultural and pedagogical) in the classroom; and for the ways in which returnees are undertaking new roles and responsibilities that exploit their new understandings. Finally, we discuss the implications of these findings for both providers and sponsors of CPD for English language teachers.

Access to knoledge in Brazil: new research on intellectual property, innovation and development

The present volume is the fruit of a research initiative on Access to Knowledge begun in 2004 by Yochai Benkler, Eddan Katz, and myself. Access to Knowledge is both a social movement and an approach to international and domestic policy. In the present era of globalization, intellectual property and information and communications technology are major determinants of wealth and power. The principle of access to knowledge argues that we best serve both human rights and economic development through policies that make knowledge, knowledge-creating tools, and nowledgeembedded goods as widely available as possible for decentralized innovation and use. Open technological standards, a balanced approach to intellectual property rights, and expansion of an open telecommunications infrastructure enable ordinary people around the world to benefit from the technological advances of the information age and allow them to generate a vibrant, participatory and democratic culture. Law plays a crucial role in securing access to knowledge, determining whether knowledge and knowledge goods are shared widely for the benefit of all, or controlled and monopolized for the benefit of a few.

Open innovation and the challenges of human resource management

This paper considers challenges of Human Resource Management (HRM) in Open Innovation processes. It examines which strategies managers used to overcome these problems in the case of the Brazilian Oil and Gas company Petrobras. By conducting an inductive case study it develops a contextual model based on the use of grounded theory. It argues that the most important categories were to overcome problems of (a) the interpersonal relationship, (b) power shifting inside the organization, and (c) making people more valuable to the organization and shows how managers tackled these challenges. It contributes with a deep analysis of HRM challenges in Open Innovation that is important for a better understanding of management problems that can come along with Open Innovation processes.

An entry strategy with innovation and differentiation in Brazil and the United States

With the global rise of credit and debit card usage, acquirers play an increasingly important role within the payments industry by processing these types of payment transactions on behalf of merchants. This study focuses on examining two markets – Brazil and the United States – by providing an overview of the market dynamics, the state of the competitive landscape, and the role and impact of regulations and new technologies. In considering these factors, strategic recommendations are provided for new players interested in enter either market. Further, factors such as existing and future opportunities as well as risks are considered.

Fostering innovation and entrepreneurship in Brazil through private equity and venture capital public policies

It is well documented the positive impact of the Private Equity and Venture Capital (PE/VC) industry on the creation and development of highly successful innovative companies in a few countries, mainly in the United States. PE/VC firms provide not only capital to startups and small and medium enterprises (SMEs) that usually have financing gap, especially in emerging markets, but also strategic resources that enable these enterprises to commercialize innovation. As consequence, government incentive and nurture of local PE/VC industries would be expected in emerging economies due to innovation‟s importance to economic growth. This paper aims to identify if the Brazilian government has supported local PE/VC industry throughout the years in order to foster favorable conditions to creating and developing successful innovative businesses. It also analyzes Brazil‟s main public policies towards PE/VC and if they encompass all the three stages of its cycle – fundraising, investing and exiting. I conducted an empirical research which collected primary data from a sample of 127 PE/VC firms (90% of the population) operating in Brazil as of June, 2008. All firms answered a webbased questionnaire that collected quantitative data regarding their investment vehicles, portfolio companies, investments and exits. I compared the data obtained from the survey with the main local governmental PE/VC support programs. First, I confirmed the hypothesis that the Brazilian government has been using the PE/VC industry as a public policy towards entrepreneurship and innovation. Second, I identified that although PE/VC public policies in Brazil are mostly concentrated in fundraising phase, they have been able to positively impact the whole cycle. Third, it became clear that the Brazilian government became more concerned about Seed and Venture Capital (VC) Early stages due to their importance to the entire PE/VC value chain. As consequence, I conclude that those public policies have been very important to build a dynamic and strong local PE/VC industry, whose committed capital grew 50% per year between 2005 and 2008 to achieve US$27 billion, which invested US$ 11 billion, which employs 1,400 professionals (75% with postgraduate degrees) and maintains 482 portfolio companies, mostly SMEs. In addition, PE/VCbacked companies represented one third of the Initial Public Offerings (IPOs) that occurred in Brazil between 2004 and 2008 (approximately US$15 billion).

Osmotic dehydration of apples in sugar/salt solutions: Concentration profiles and effective diffusion coefficients

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Concentration profiles and effective diffusion coefficients of sucrose and water in osmo-dehydrated apples

The spatial distribution of water and sugars in half-fresh apples dehydrated in sucrose solutions (30% and 50% w/w, 27 degrees C) for 2, 4 and 8 h, was determined. Each half was sliced as from the exposed surface. The density, water and sugar contents were determined for each piece. A mathematical model was fitted to the experimental data of the water and sucrose contents considering the overall flux and tissue shrinkage. A numerical method of finite differences permitted the calculation of the effective diffusion coefficients as a function of concentration, using material coordinates and integrating the two differential equations (for water and sucrose) simultaneously. The coefficients obtained were one or even two orders of magnitude lower than those for pure solutions and presented unusual concentration dependence. The behaviour of the apple tissue was also studied using light microscopy techniques to obtain images of the osmotically treated pieces (20%, 30% and 50% w/w sucrose solutions for 2, 4 and 8 h).

Evaluation of water and sucrose diffusion coefficients in potato tissue during osmotic concentration

The water and sucrose effective diffusion coefficients behavior were studied in potato tubers immersed in aqueous sucrose solution, 50% (w/,A), at 27 degreesC. Water and sucrose concentration profiles were measured as function of the position for 3, 6 and 12 h of immersion. These were adjusted to a mathematical model for three components that take into account the bulk flow in a shrinking tissue and the concentration dependence of the diffusion coefficients.The binary effective coefficients were an order of magnitude lower than those for pure solutions of sucrose. These coefficients show an unusual concentration dependence. Analysis of these coefficients as functions of the concentration and position demonstrates that, cellular tissue promotes high resistance to diffusion in the tuber and also the elastic contraction of material influences the species diffusion.

Squeezed states, generalized Hermite polynomials and pseudo-diffusion equation

We show that the wavefunctions 〈pq; λ|n〈, of the harmonic oscillator in the squeezed state representation, have the generalized Hermite polynomials as their natural orthogonal polynomials. These wavefunctions lead to generalized Poisson Distribution Pn(pq;λ), which satisfy an interesting pseudo-diffusion equation: ∂Pnp,q;λ) ∂λ= 1 4 [ ∂2 ∂p2-( 1 λ2) ∂2 ∂q2]P2(p,q;λ), in which the squeeze parameter λ plays the role of time. Th entropies Sn(λ) have minima at the unsqueezed states (λ=1), which means that squeezing or stretching decreases the correlation between momentum p and position q. © 1992.
