Coumarins and phenolic fingerprints of oak and Brazilian woods extracted by sugarcane spirit

A total of 25 sugarcane spirit extracts of six different Brazilian woods and oak, commonly used by cooperage industries for aging cachaca, were analyzed for the presence of 14 phenolic compounds (ellagic acid, gallic acid, vanillin, syringaldehyde, synapaldehyde, coniferaldehyde, vanillic acid, syringic acid, quercetin, trans-resveratrol, catechin, epicatechin, eugenol, and myricetin) and two coumarins (scopoletin and coumarin) by HPLC-DAD-fluorescence and HPLC-ESI-MS(n). Furthermore, an HPLC-DAD chromatographic fingerprint was build-up using chemometric analysis based on the chromatographic elution profiles of the extracts monitored at 280 nm. Major components identified and quantified in Brazilian wood extracts were coumarin, ellagic acid, and catechin, whereas oak extracts shown a major contribution of catechin, vanillic acid, and syringaldehyde. The main difference observed among oak and Brazilian woods remains in the concentration of coumarin, catechin, syringaldehyde, and coniferaldehyde. The chemometric analysis of the quantitative profile of the 14 phenolic compounds and two coumarins in the wood extracts provides a differentiation between the Brazilian wood and oak extracts. The chromatographic fingerprint treated by multivariate analysis revealed significant differences among Brazilian woods themselves and oak, clearly defining six groups of wood extracts: (i) oak extracts, (ii) jatoba extracts, (iii) cabreuva-parda extracts, (iv) amendoim extracts, (v) canela-sassafras extracts and (vi) pequi extracts.

How transnational environmental advocacy networks socialize international financial institutions: a case study of the international finance corporation

Environmental organizations, characterized here as transnational advocacy networks, use various strategies to "green" international financial institutions (IFIs). This article goes beyond analyzing network strategies to examine how transnational advocacy networks reconstitute the identity of IFIs. This, it is argued, results from processes of socialization: social influence, persuasion and coercion by lobbying. A case study of the International Finance Corporation (IFC), as a member of the World Bank Group, is used to analyze how an IFI internalized sustainable development norms. The IFC finances private enterprise in developing countries by providing venture capital for private projects. Transnational advocacy networks socialized the IFC through influencing its projects, policies and institutions via direct and indirect interactions to the point where the organization now sees itself as a sustainable development financier. This article applies constructivist insights to the greening process in order to demonstrate how socialization can reshape an IFI's identity.

Managing change without sacrificing quality: music teaching and learning at South African tertiary institutions

After the jubilation of the first democratic election in 1994, South African educational settings were faced with the challenge to rethink curriculum, content and delivery as part of its nation building process. Education continues to be a major player in stimulating wider change in society and is one arena where change may be readily facilitated. Changing the style and practice of teacher education programs remains a key feature in the transformation process. Twelve years on, curriculum, has undergone reform in terms of Outcomes Based Education (OBE)? Revised National Curriculum Statement (RNCS) of 2002, accordingly, universities continue to prepare teachers for multicultural classrooms. Universities are now challenged to manage increased student intake (quantity) for teacher education programs without having to sacrifice quality for teacher education. This article focuses only on The University of Pretoria, a city university previously known as a traditional Afrikaans university situated in the greater Johannesburg area in South Africa. Through interview data with two music educators at this university, I present some of the current trends and challenges that tertiary music educators face in preparing music teachers in South Africa. This article also outlines a paradigm shift in the curriculum and argues for a holistic music education, one that endorses most of the major cultures and musics in South Africa. The question I pose is how then do we effectively manage change at tertiary level without sacrificing quality when preparing future music teachers to meet the needs and challenges of the curriculum and society.

Labour market institutions and the gender wage gap in Britain and Australia, 1973-90

The importance of wage structure is frequently interpreted as indirect evidence of the role played by labour market institutions. The current paper follows in this tradition, examining the role of wage structure in explaining the trend in the gender wage gap over the period 1973–91 for both Australia and the UK. The focus is upon whether changes in wage structure (and associated gender wage gap) both across country and over time are compatible with institutional explanations. Combining comparisons both cross‐country and over time yields a more stringent, albeit indirect, test of the role of institutions.

Understanding what microfinance institutions need to address to aid poverty alleviation, social inclusion and human development

Poverty, in its most basic form can be defined as a deprivation of well-being. It is an issue that has been evident in society for centuries and a concern for government policy makers and more recently for non-government organizations (NGOs). In this paper, we consider how management approaches to resolving the dilemma of poverty can be advanced by drawing on two major areas in the development arena associated with poverty, namely, ‘social exclusion’ and ‘the human development paradigm’. We put forward the argument that for groups of people where social disintegration has already occurred, only structural interventions coupled with a social development mechanism will achieve the desired effect. One method for achieving this is through the use of microfinance programs which provide a broad range of financial services to the poor and low-income households as well as to micro-enterprises. This paper contributes to both management practice and theory by developing a theoretical model that microfinance institutions need to do to aid both ‘human development’ and ‘social inclusion’ processes for the socially excluded and poor.
