Identifying and discriminating among lucerne cultivars using plant morphological characters

The use of morphological data obtained from field (plot test) and glasshouse trials to identify and discriminate among four Iranian and two New Zealand lucerne (Medicago sativa L.) cultivars was investigated, following guidelines established by the International Union for the Protection of New Varieties of Plants (UPOV) for cultivar registration and the Organisation for Economic Co-operation and Development (OECD) for seed certification. Data were collected for terminal leaflet length, width and ratio, angle of stem growth, date of first flowering, stem height at first flowering, flower colour, cutting recovery height, and disease scores. None of these characters were sufficient to identify or discriminate among the six cultivars. The results indicate a need to find cost-effective and efficient laboratory techniques to enhance the assessment of distinctness of lucerne cultivars (UPOV) and for determining cultivar purity for lucerne seed certification (OECD).

Teachers' perceptions of the national board certification process: Developing a sense of professionalism

This study describes and explains the experiences and perceptions of six public school teachers who had undergone the National Board for Professional Teaching Standards national certification process as a vehicle for promoting a teacher's sense of professionalism. Of these six participants, two achieved National Board certification, two did not achieve National Board certification, and two are awaiting results of their certification status. The study took place over a period of eleven months and focused on the participants' perceptions regarding the National Board certification process as it affected their sense of (a) efficacy and (b) professionalism. Data for this collective case study were gathered from interviews, portfolios and videotapes, and artifacts. Using case analysis, this study's participants' responses gathered through the interview process were examined. ^ The findings indicated that participants had concerns about the National Board certification process in the following areas: process, sense of efficacy, and sense of professionalism. All participants reported the process to be overwhelmingly demanding. Analysis of the data also reveals that those who were successful in achieving National Board certification had a greater sense of efficacy than those who did not. A disappointing finding was that the National Board process impacting participants' sense of professionalism could not be sustained; however, the participants in this study suggested the process was a step towards providing opportunities for collaboration, collegiality, and reflective practice. This study raises the question as to whether or not the espoused purposes of National Board certification are achieved via the certification process. ^

Left behind: A farmer's fate in the age of sustainable development

Globalization is eroding the livelihoods of small farmers, a significant and vulnerable class, particularly in the developing world. The cost-price squeeze stemming from trade liberalization places farmers in a race to the bottom that leads to displacement, poverty, and environmental degradation. Scholars and activists have proposed that alternative trade initiatives offer a unique opportunity to reverse this trend by harnessing the power of the markets to reward producers of goods with embedded superior cultural, environmental, and social values. Alternative trade via certification schemes have become a de facto prescription for any location where there is a need to conciliate economic interest with conservation imperatives. Partnerships among commodity production farmers, elite manufacturers and wealthy northern consumers/activists do not necessarily have win-win outcomes. Paradoxically, the partnerships of farmers with external agencies have unexpected results. These partnerships develop into dependent relationships that become unsustainable in the absence of further transfers of capital. The institutions born of these partnerships are fragile. When these fledging institutions fail, farmers are left in the same situation that they were before the partnership, with only minor improvements to show after spending considerable amounts of social and financial capital. I hypothesize that these failures are born out of a belief in a universal understanding of sustainability. A discursive emphasis on consensus, equity and mutual benefit hides the fact that what for consumers it is a matter of choice, for producers is a matter of survival. The growth in consumers’ demand for certified products creates a race for farmers to meet these standards. My findings suggest that this race generates economically perverse effects. First, producers enter into a certification treadmill. Second, the local need for economic sustainability is ignored. Third, commodity based alternative trade schemes increase the exposure of communities to global shocks. I conclude by calling for a careful reassessment of sustainable development projects that promote certification schemes. The designers and implementers of these programs must include farmers’ agenda in the planning of these programs.

Small farmer market knowledge and specialty coffee commodity chains in Western Highlands Guatemala

For producers motivated by their new status as self-employed, landowning, capitalist coffee growers, specialty coffee presents an opportunity to proactively change the way they participate in the international market. Now responsible for determining their own path, many producers have jumped at the chance to enhance the value of their product and participate in the new "fair trade" market. But recent trends in the international coffee price have led many producers to wonder why their efforts to produce a certified Fair Trade and organic product are not generating the price advantage they had anticipated. My study incorporates data collected in eighteen months of fieldwork, including more than 45 interviews with coffee producers and fair trade roasters, 90 surveys of coffee growers, and ongoing participant observation to understand how fair trade certification, as both a market system and development program, meets the expectations of the coffee growers. By comparing three coffee cooperatives that have engaged the Fair Trade system to disparate ends, the results of this investigation are three case studies that demonstrate how global processes of certification, commodity trade, market interaction, and development aid effect social and cultural change within communities. This study frames several lessons learned in terms of (1) socioeconomic impacts of fair trade, (2) characteristics associated with positive development encounters, and (3) potential for commodity producers to capture value further along their global value chain. Commodity chain comparisons indicate the Fair Trade certified cooperative receives the highest per-pound price, though these findings are complicated by costs associate with certification and producers' perceptions of an "unjust" system. Fair trade-supported projects are demonstrated as more "successful" in the eyes of recipients, though their attention to detail can just as easily result in "failure". Finally, survey results reveal just how limited is the market knowledge of producers in each cooperative, though fair trade does, in fact, provide a rare opportunity for producers to learn about consumer demand for coffee quality. Though bittersweet, the fair trade experiences described here present a learning opportunity for a wide range of audiences, from the certified to the certifiers to the concerned public and conscientious consumer.

Disparities in Teacher Certification

The United States Constitution did not give the federal government the power to regulate education. Consequently there is a lack of cohesion and standardization within the United States in teacher certification. The differences and quantity of teacher training and certification leads to inconsistency in teacher certification.

Municipal accountability: Should regulations similar to the Sarbanes -Oxley Act apply to the local sector?

As America moved into the 2lst century financial scandals associated with large publicly traded corporations brought widespread concern about the reliability of financial reporting. In response the U.S. Congress adopted the Sarbanes-Oxley Act of 2002 (SOX). Undergirding SOX was the belief that improvements in the reliability of an organization's financial disclosures would lead to increased trust in the issuing organization. While SOX is aimed at publicly traded private sector organizations, the value of adopting SOX-like practices in the public and the nonprofit sectors have been recognized. Although SOX-like auditing practices have not at the time of this research become part of the auditing regime for municipalities, the results of this research provide a baseline "read" of municipal finance officers' perceptions of the value and obstacles associated with adoption of two major components of SOX: Principal Officer(s) Certification (POC) and the Independent Audit Committee (IAC) requirements. The author mailed surveys to all finance officers of municipalities in Florida and Ohio with populations of 10,000 or greater which did not contract out the operation of their finance departments. Post-survey "elite" interviews were conducted in an effort to obtain a deeper understanding of revealed issues and contradictions found in the analysis of the results of the mails survey. The findings suggest municipal finance officers are willing to adopt POC but have reservations about implementing IAC. With both POC and IAC the respondents appeared to consider intangible, non-pecuniary consequences as much or more than tangible, pecuniary consequences. Consistent with prior research, attitudes regarding POC and IAC were found to be unrelated to prior adoptive behavior, or personal and organizational demographic variables. Although accounting and auditing are inexorably intertwined, views of the recently implemented GASB 34 reporting model were found to be unrelated to the willingness to adopt POC or IAC. Findings dovetail with current discourse in public sector accounting suggesting local finance professionals may see benefits—both tangible and intangible—to some but not all accounting practices adopted in the private sector. This is consistent with the commonly accepted belief that public sector accounting maintains fundamental differences from its private counterpart.

Natal qual é a sua cara?: análise do perfil edilício da avenida Eng. Roberto Freire (Natal/RN) à luz da acessibilidade

This study focuses on the building ensemble of Avenida Roberto Freire, a main road in Natal, Brazil, as a material expression of the confluence of various factors among which the following may be emphasized: high level of accessibility due to urban spatial re-structuring and the growth of the real estate market, in view of the increasing number of consumers, who arrived in Natal within the last decades. The intense urban modification process that has been going on in Natal since at least the 1980s, has engendered the formation of long axial lines which express the expansion dynamics and some of the forces subjacent to it. Avenida Roberto Freire has been an iconic example of an urban thoroughfare where architecture becomes primarily a communication support that can be perceived by fast moving passers-by, what brings it close to the venturian concept of strip (Venturi at al, 1972). The building types that line the road not only respond to the dynamics in process but also contribute to intensify it, as they house a variety of uses which attract people and generate more movement. The dynamics is further strengthened by the action of the real estate business which benefits from the increase of highly accessible locations, and from the private and public investments and incentives to tourism that aim to insert this city into the globalized world. Although the intention of reconstituting part of the history of density increase on this avenue in a diachronical perspective was attempted within the limits of the available references and documentation, the central contribution of this study is to understand the relations between topological accessibility and the typological nature of the building ensemble. By observing the synchronic morphological frame resulting from the spatial configuration analysis pertinent to this avenue (cf. Hillier and Hanson,1984) and the inventory and classification of the building ensemble there existing, this study aims to understand how architecture responds to accessibility in view of the real estate pressure, boosted by a cosmopolitanizing process brought about by the continuous flow of foreign and Brazilian arrivals as visitors, temporary or permanent residents

Between Bacchus and Dionysus: European Union policies on rural development: the cases of Nemea and Basto wine regions

A actividade vitivinícola possui um conjunto diverso de características presentes no solo, território e comunidade que fazem parte do património cultural de uma determinada região. Quando a tradição se traduz num conceito como terroir que é formado por características territoriais, sociais e culturais de uma região rural, o vinho apresenta uma “assinatura” que se escreve “naturalmente” no paladar regionalmente identificado. Os vinhos da Região de Nemea, na Grécia e de Basto (Região dos Vinhos Verdes) em Portugal, estão ambos sob a proteção dos regulamentos das Denominações de Origem. No entanto, apesar de ambos serem regulados por sistemas institucionais de certificação e controlo de qualidade, afigura-se a necessidade de questionar se o património cultural e a identidade territorial específica, “impressa” em ambos os terroirs, pode ser protegida num sentido mais abrangente do que apenas origem e qualidade. Em Nemea, a discussão entre os produtores diz respeito ao estabelecimento de sub-zonas, isto é incluir na regulação PDO uma diferente categorização territorial com base no terroir. Ou seja, para além de estar presente no rótulo a designação PDO, as garrafas incluirão ainda informação certificada sobre a área específica (dentro do mesmo terroir) onde o vinho foi produzido. A acontecer resultaria em diferentes status de qualidade de acordo com as diferentes aldeias de Nemea onde as vinhas estão localizadas. O que teria possíveis impactos no valor das propriedades e no uso dos solos. Para além disso, a não participação da Cooperativa de Nemea na SON (a associação local de produtores de vinho) e como tal na discussão principal sobre as mudanças e os desafios sobre o terroir de Nemea constitui um problema no sector vitivinícola de Nemea. Em primeiro lugar estabelece uma relação de não-comunicação entre os dois mais importantes agentes desse sector – as companhias vinícolas e a Cooperativa. Em segundo lugar porque constituiu uma possibilidade real, não só para os viticultores ficarem arredados dessa discussão, como também (porque não representados pela cooperativa) ficar impossibilitado um consenso sobre as mudanças discutidas. Isto poderá criar um ‘clima’ de desconfiança levando a discussão para ‘arenas’ deslocalizadas e como tal para decisões ‘desterritorializadas’ Em Basto, há vários produtores que começaram a vender a sua produção para distribuidoras localizadas externamente à sub-região de Basto, mas dentro da Região dos Vinhos Verdes, uma vez que essas companhias tem um melhor estatuto nacional e internacional e uma melhor rede de exportações. Isto está ainda relacionado com uma competição por uma melhor rede de contactos e status mais forte, tornando as discussões sobre estratégias comuns para o desenvolvimento rural e regional de Basto mais difícil de acontecer (sobre isto a palavra impossível foi constantemente usada durante as entrevistas com os produtores de vinho). A relação predominante entre produtores é caracterizada por relações individualistas. Contudo foi observado que essas posições são ainda caracterizadas por uma desconfiança no interior da rede interprofissional local: conflitos para conseguir os mesmos potenciais clientes; comprar uvas a viticultores com melhor rácio qualidade/preço; estratégias individuais para conseguir um melhor status político na relação com a Comissão dos Vinhos Verdes. Para além disso a inexistência de uma activa intermediação institucional (autoridades municipais e a Comissão de Vinho Verde), a inexistência entre os produtores de Basto de uma associação ou mesmo a inexistência de uma cooperativa local tem levado a região de Basto a uma posição de subpromoção nas estratégias de promoção do Vinho Verde em comparação com outras sub-regiões. É também evidente pelos resultados que as mudanças no sector vitivinícolas na região de Basto têm sido estimuladas de fora da região (em resposta também às necessidades dos mercados internacionais) e raramente de dentro – mais uma vez, ‘arenas’ não localizadas e como tal decisões desterritorializadas. Nesse sentido, toda essa discussão e planeamento estratégico, terão um papel vital na preservação da identidade localizada do terroir perante os riscos de descaracterização e desterritorialização. Em suma, para ambos os casos, um dos maiores desafios parece ser como preservar o terroir vitivinícola e como tal o seu carácter e identidade local, quando a rede interprofissional em ambas as regiões se caracteriza, tanto por relações não-consensuais em Nemea como pelo modus operandi de isolamento sem comunicação em Basto. Como tal há uma necessidade de envolvimento entre os diversos agentes e as autoridades locais no sentido de uma rede localizada de governança. Assim sendo, em ambas as regiões, a existência dessa rede é essencial para prevenir os efeitos negativos na identidade do produto e na sua produção. Uma estratégia de planeamento integrado para o sector será vital para preservar essa identidade, prevenindo a sua desterritorialização através de uma restruturação do conhecimento tradicional em simultâneo com a democratização do acesso ao conhecimento das técnicas modernas de produção vitivinícola.

The European Registered Toxicologist (ERT): Current status and prospects for advancement

Following its inception in 1994, the certification of European Registered Toxicologists (ERT) by EUROTOX has been recognized as ensuring professional competence as well as scientific integrity and credibility. Criteria and procedures for registration are contained in the ERT "Guidelines for Registration 2012". The register of ERT currently has over 1900 members. In order to continue the harmonisation of requirements and processes between national registering bodies as a prerequisite for official recognition of the ERT title as a standard, and to take account of recent developments in toxicology, an update of the ERT Guidelines has been prepared in a series of workshops by the EUROTOX subcommittees for education and registration, in consultation with representatives of national toxicology societies and registers. The update includes details of topics and learning outcomes for theoretical training, and how these can be assessed. The importance of continuing professional development as the cornerstone of re-registration is emphasised. To help with the process of harmonisation, it is necessary to collate and share best practices of registration conditions and procedures across Europe. Importantly, this information can also be used to audit compliance with the EUROTOX standards. As recognition of professionals in toxicology, including specialist qualifications, is becoming more important than ever, we believe that this can best be achieved based on the steps for harmonisation outlined here together with the proposed new Guidelines.

The impact of geometric non-linearities on the fatigue analysis of trailing edge bond lines in wind turbine rotor blades

The accurate prediction of stress histories for the fatigue analysis is of utmost importance for the design process of wind turbine rotor blades. As detailed, transient, and geometrically non-linear three-dimensional finite element analyses are computationally weigh too expensive, it is commonly regarded sufficient to calculate the stresses with a geometrically linear analysis and superimpose different stress states in order to obtain the complete stress histories. In order to quantify the error from geometrically linear simulations for the calculation of stress histories and to verify the practical applicability of the superposition principal in fatigue analyses, this paper studies the influence of geometric non-linearity in the example of a trailing edge bond line, as this subcomponent suffers from high strains in span-wise direction. The blade under consideration is that of the IWES IWT-7.5-164 reference wind turbine. From turbine simulations the highest edgewise loading scenario from the fatigue load cases is used as the reference. A 3D finite element model of the blade is created and the bond line fatigue assessment is performed according to the GL certification guidelines in its 2010 edition, and in comparison to the latest DNV GL standard from end of 2015. The results show a significant difference between the geometrically linear and non-linear stress analyses when the bending moments are approximated via a corresponding external loading, especially in case of the 2010 GL certification guidelines. This finding emphasizes the demand to reconsider the application of the superposition principal in fatigue analyses of modern flexible rotor blades, where geometrical nonlinearities become significant. In addition, a new load application methodology is introduced that reduces the geometrically non-linear behaviour of the blade in the finite element analysis.
