PDA, Circulation, and Over-Budget Requests: Harnessing Data to Inform Library Strategies

This article presents the data-rich findings of an experiment with enlisting patron-driven/demand-driven acquisitions (DDA) of ebooks in two ways. The first experiment entailed comparison of DDA eBook usage against newly ordered hardcopy materials’ circulation, both overall and ebook vs. print usage within the same subject areas. Secondly, this study experimented with DDA ebooks as a backup plan for unfunded requests left over at the end of the fiscal year.

An Environmental Analysis Corroborating PDA and the Winthrop Example

Libraries seek active ways to innovate amidst macroeconomic shifts, growing online education to help alleviate ever-growing schedule conflicts as students juggle jobs and course schedules, as well as changing business models in publishing and evolving information technologies. Patron-driven acquisition (PDA), also known as demand-driven acquisition (DDA), offers numerous strengths in supporting university curricula in the context of these significant shifts. PDA is a business model centered on short-term loans and subsequent purchases of ebooks resulting directly from patrons' natural use stemming from their discovery of the ebooks in library catalogs where the ebooks' bibliographic records are loaded at regular intervals established between the library and ebook supplier. Winthrop University's PDA plan went live in October 2011, and this article chronicles the philosophical and operational considerations, the in-library collaboration, and technical preparations in concert with the library system vendor and ebook supplier. Short-term loan is invoked after a threshold is crossed, typically number of pages or time spent in the ebook. After a certain number of short-term loans negotiated between the library and ebook supplier, the next short-term loan becomes an automatic purchase after which the library owns the ebook in perpetuity. Purchasing options include single-user and multi-user licenses. Owing to high levels of need in college and university environments, Winthrop chose the multi-user license as the preferred default purchase. Only where multi-user licenses are unavailable does the automatic purchase occur with single-user title licenses. Data on initial use between October 2011 and February 2013 reveal that of all PDA ebooks viewed, only 30% crossed the threshold into short-term loans. Of all triggered short-term loans, Psychology was the highest-using. Of all ebook views too brief to trigger short-term loans, Business was the highest-using area. Although the data are still too young to draw conclusions after only a few months, thought-provoking usage differences between academic disciplines have begun to emerge. These differences should be considered in library plans for the best possible curricular support for each academic program. As higher education struggles with costs and course-delivery methods libraries have an enduring lead role.

Extração de boro de água produzida sintética por sistema microemulsionado

Boron is a semi-metal present in certain types of soils and natural waters. It is essential to the healthy development of plants and non-toxic to humans, depending on its concentration. It is used in various industries and it s present in water production coming from oil production. More specifically in Rio Grande do Norte, one of the largest oil producers on shore of Brazil, the relationship water/oil in some fields becomes more than 90%. The most common destination of this produced water is disposal in open sea after processing to meet the legal specification. In this context, this research proposes to study the extraction of boron in water produced by microemulsion systems for industrial utilization. It was taken into account the efficiency of extraction of boron related to surfactant (DDA and OCS, both characterized by FT-IR), cosurfactant (butanol and isoamyl alcohol), organic phase (kerosene and heptanes) and aqueous phase (solution of boron 3.6 ppm in alkaline pH). The ratio cosurfactant/ surfactant used was four and the percentage of organic phases for all points of study was set at 5%. It was chosen points with the highest percentage of aqueous phase. Each system was designed for three points of different compositions in relation to the constituents of a pseudoternary diagram. These points were chosen according to studies of phase behavior in pseudoternary diagrams made in previous studies. For this research, points were chosen in the Winsor II region. The excess aqueous solution obtained in these systems was separated and analyzed by ICP OES. For the data set obtained, the better efficiency in the extraction of boron was obtained using the system with DAC, isoamyl alcohol and heptanes, which extracted 49% in a single step. OCS was not viable to the extraction of boron by microemulsion system in the conditions defined in this study

A mídia impressa sergipana nas eleições para governador em 2006: cobertura do Cinform, correio de Sergipe e jornal da cidade

The elections for governor in 2006 with its victory Marcelo Déda Workers Party (PT), were a landmark in the state of Sergipe, for the first time, called progressive fronts (an alliance of parties formed mostly by origin of the left) broke the hegemony of two political groups, Franco and the Alves, whose direction was in force for over 30 years. This study proceeds on the assumption that the print media has certain standards of conduct in covering the election period. Therefore, this study seeks to quantify, classify and compare data from three newspapers more representative of the State of Sergipe (Cinform, Cidade Journal and Correio de Sergipe) to analyze the behavior of these journals, such as private apparatus of hegemony in election coverage 2006. It also uses the concept of hegemony Gramsci and theories of journalism framing (Entman and Porto) and agenda setting (McCombs and Shaw) to identify these patterns

Digital radiography using digital detector arrays fulfills critical applications for offshore pipelines

Digital radiography in the inspection of welded pipes to be installed under deep water offshore gas and oil pipelines, like a presalt in Brazil, in the paper has been investigated. The aim is to use digital radiography for nondestructive testing of welds as it is already in use in the medical, aerospace, security, automotive, and petrochemical sectors. Among the current options, the DDA (Digital Detector Array) is considered as one of the best solutions to replace industrial films, as well as to increase the sensitivity to reduce the inspection cycle time. This paper shows the results of this new technique, comparing it to radiography with industrial films systems. In this paper, 20 test specimens of longitudinal welded pipe joints, specially prepared with artificial defects like cracks, lack of fusion, lack of penetration, and porosities and slag inclusions with varying dimensions and in 06 different base metal wall thicknesses, were tested and a comparison of the techniques was made. These experiments verified the purposed rules for parameter definitions and selections to control the required digital radiographic image quality as described in the draft international standard ISO/DIS 10893-7. This draft is first standard establishing the parameters for digital radiography on weld seam of welded steel pipes for pressure purposes to be used on gas and oil pipelines.

Acúmulo de sacarose, produtividade e florescimento de cana-de-açúcar sob reguladores vegetais

Plant regulators have been used successfully for early ripening and flowering control in sugarcane (Saccharum spp. Hybrid). However, little information is available about the interactions between new genotypes and two plant regulators with regard to those variables. This study determined the effect of the regulators on the sucrose content, stalk production and flowering of seven sugarcane genotypes. The experiment was installed in March 2004 near Ja-, SP, Brazil A randomized complete block design was used with four blocks with a split plot treatment arrangement where the main plots were the genotypes IAC87-3396, IAC87-3410, IAC89-3124, IAC91-2195, 1AC91-5155, P088-62 and SP80-1842 and the subplots were sulfomethuron-methyl (15g i.a.·ha -1), etefon (480g i.a.·ha-1) and unsprayed control. Pol in cane was evaluated at 0, 21, 42, 63, 84, 105 and 126 days after the plant regulators application (DAA). Flowering, pith, stalk production and sucrose content were evaluated at 126 DAA. In most of the genotypes the use of plant regulators anticipated maturation in 21 days when compared with the unsprayed control. Etefon was more efficient for harvesting sugarcane between 42-84 DAA, whereas sulfomethuron-methyl was between 105 and 126 DDA. Both products controlled flowering. For most genotypes, the ripeners did not affect the productivity of stalks, except for sulfomethuron-methyl that reduced it in SP80-1842, and for ethephon that increased it in IAC91-2195. Sugar productivity of IAC89-3124 increased with both regulators, while it was higher in IAC91-2195 with ethephon application and lower in SP80-1842 with sulfomethuron-methyl use.

Review of CARIFORUM-EU EPA in development cooperation and WTO compatability

The Cotonou Agreement which succeeded the Lomé IV Agreement and was signed in Cotonou in June 2000 established a comprehensive framework to govern social, economic and political relations between the Africa, Caribbean, Pacific (ACP) grouping and the European Union (EU). At the centre of the partnership are objectives relating to economic development, the reduction and eventual eradication of poverty, and the smooth and gradual integration of ACP States into the world economy. In order to accomplish these objectives, the Cotonou Agreement provides for the conclusion between the ACP and the EU of “new World Trade Organization (WTO) compatible trading arrangements, removing progressively barriers to trade between them and enhancing cooperation in all areas relevant to trade” (Article 36.1). The conclusion of economic partnership agreements (EPAs) represented one way to achieve a WTO compatible instrument and had to be negotiated during the period starting from September 2002 until 31 December 2007 to replace the trade provisions of the Cotonou Agreement. After three and half years of negotiations, CARIFORUM and the European Commission (EC) finally concluded a comprehensive EPA with the EC on 16 December 2007 when an Agreement was initialed. The EPA Parties agreed to sign it later after a review of the provisions at both the national and regional levels. In CARIFORUM, various comments have been made from governments, Nongovernmental organizations (NGOs), the private sector and the labour movement about the strengths and weaknesses of the EPA. This review comes in this context and is confined to the development cooperation provisions and the question of WTO compatibility and consistency with the Doha Development Agenda (DDA) negotiations and existing WTO provisions on special and differential treatment.
