Lessonia berteroana (ex L. nigrescens) is kelp freely harvested from Open Access Areas (OAA), and to some extent controlled, from Management and Exploitation Areas for Benthic Resources (MEABR). Harvesting pressures can change population dynamics, mainly in OAAs. In particular, harvesting may alter the chemical components of plants. Therefore, the aim of this study was to determine the harvesting effects on the chemical composition of L. berteroana from MEABR and OAA sampled during different seasons (spring and fall) and at two sites (Talquilla and Lagunillas) near Coquimbo (30°S), Chile. The crude protein (13.5 ± 1.0%), total lipids (0.9 ± 0.2%), crude fiber (16.3 ± 1.6%), ash (30.1 ± 1.5%), and nitrogen-free extract (39.2 ± 2.0%) contents of L. berteroana were within reference values for Laminariales species. Population descriptors and chemical analyses showed that harvesting had local effects, rather than being affected by a resource management strategy (OAA vs MEABR). The seasonal anticipator nature of L. berteroana may explain the detected seasonality of it's chemical composition. Regarding functional morphological structures, chemical composition in the fronds was more variable than in the stipes and perennial holdfast, probably since leaves are ephemeral structures susceptible to environmental changes and that play a functional, rather than structural, role in kelp. In the context of Chilean kelp resource management, monitoring chemical composition is useful for determining optimal harvesting periods to local scale and for deciding when commercially valuable compounds, such as alginate, should be extracted. These data also complement harvesting pressure indicators based on L. berteroana demographic parameters.

How fast is open access growing? Is this fast enough? Why or why not? What are the impacts of currently evolving open systems? For instance, are overall costs being reduced for scholarly libraries? Is global access to scholarly information increasing? What about in the Global South? What is the impact in this region of increasing adoption of the author-pays system?

Abstract The paper investigates the capabilities for open access to resource management in multimedia networks through Parlay X Web Services. Resource management allows the network operator to provide Quality of Service (QoS) to user sessions and to apply advanced charging. The study is based on the analysis of Policy and Charging Control (PCC) functions defined for evolved packet systems The PCC comprises flow-based charging including charging control and online credit control, gating control, and Quality of Service Control (QoS) control. The required functionality for open access to QoS management and advanced charging is identified. Parlay X Web Services are evaluated for the support of PCC and some enhancements are suggested. Implementation aspects are discussed and Parlay X interfaces are mapped on IMS control protocols. Use Cases of Parlay X Web services for PCC are presented.

Electronic resources (e-resources) have become an integral part of libraries’ resources in many parts of the world and enable libraries to meet users’ needs whenever and wherever they are located. Open access (OA) resources similarly decrease financial and geographic barriers to using content. Libraries incorporate open resources into their collections to enhance or replace their subscribed content. As pressure mounts for authors and publishers to make content open, many libraries also support the creation and provision of OA materials. During unexpected disruptions, such as the 2020 coronavirus pandemic, these subscription-based and OA resources enable libraries to continue to meet their users’ needs as they cancel events, close physical locations, and support efforts to move courses and workplaces entirely online. Techniques for Electronic Resource Management: TERMS and the Transition to Open provides a thorough and sophisticated overview of the work that goes into supporting these types of resources.
