Cilj. Rad daje prikaz utjecaja tehnoloških promjena, osobito mrežne dostupnosti e-izvora znanstvenih informacija na službu međuknjižnične posudbe koristeći kao primjer podatke o međuknjižničnoj posudbi (MKP) Centra za znanstvene informacije, uz osvrt na trendove u Europi i svijetu. Pristup. Rad donosi kratak povijesni pregled razvoja službe međuknjižnične posudbe, prikaz tehnoloških promjena, s naglaskom na dostupnost građe u digitalnom formatu bilo pretplatom ili u otvorenom pristupu i promjene koje donosi, istovremeno olakšavajući proces međuknjižnične posudbe, ali i donoseći određena ograničenja. Analizirani su podaci o broju zahtjeva u Centru za znanstvene informacije Instituta Ruđer Bošković, a dat je i pregled današnje situacije u svijetu. Rezultati. Analiza je pokazala da velik broj zahtjeva za međuknjižničnom posudbom CZI bilježi sve do 2013. godine, nakon čega je registriran konstantan pad u broju zahtjeva, što je u skladu i s nekim primjerima u svijetu koji su prikazani u radu. Originalnost. Tema je obrađivana u prošlosti, no malo je novijih radova u Hrvatskoj koji obrađuju utjecaj tehnoloških promjena i digitalne građe na samu službu međuknjižnične posudbe, dajući pri tom opsežan pregled trenutnog stanja u svijetu. U svijetlu navedenih promjena su analizirani i prikazani statistički podaci međuknjižnične posudbe Centra za znanstvene informacije.

Aquatic Sciences

The need for prediction is now widely recognized and frequently articulated as an objective of research programs in aquatic science. This recognition is partly the legacy of earlier advocacy by the school of empirical limnologists. This school, however, presented prediction narrowly and failed to account for the diversity of predictive approaches as well to set prediction within the proper scientific context. Examples from time series analysis and probabilistic models oriented toward management provide an expanded view of approaches and prospects for prediction. The context and rationale for prediction is enhanced understanding. Thus, prediction is correctly viewed as an aid to building scientific knowledge with better understanding leading to improved predictions. Experience, however, suggests that the most effective predictive models represent condensed models of key features in aquatic systems. Prediction remains important for the future of aquatic sciences. Predictions are required in the assessment of environmental concerns and for testing scientific fundamentals. Technology is driving enormous advances in the ability to study aquatic systems. If these advances are not accompanied by improvements in predictive capability, aquatic research will have failed in delivering on promised objectives. This situation should spark discomfort in aquatic scientists and foster creative approaches toward prediction.

Aquatic Sciences

The aquatic sciences have their share of scientific controversies. In some cases the controversy is the classic situation of economic benefit versus environmental protection; in other cases it involves “genuine” scientific debate over uncertainties of the science or debate over what management option is optimal. This chapter discusses two pollution cases that pit scientists from universities or government agencies against those supported by the industry responsible for the pollution. Additional controversies that are also discussed are a disagreement over management options for shoreline protection, and a scientific disagreement over uncertainties in data on fish populations, which is usually the reason for controversies over fisheries. Controversies over effects of pollution often focus on how much (what concentration) of a chemical is needed to produce a certain harmful effect. Chemical companies tend to argue that levels of a chemical found in the environment are too low to cause problems, while environmentalists typically contend that lower levels can be harmful. One chemical about which there is sometimes controversy is oil. In the case of oil spills, debate commonly centers on how long the effects of pollution last. Oil degrades over time, resulting in less oil in the environment. The critical issue here is: When does this degradation reach a point where spilled oil is no longer harmful? Oil is a complex combination of various hydrocarbons that generally floats on water, although some lighter-weight components (the water-soluble fraction) dissolve. Weathering is a process that takes place in the air and water, in which the lightweight components evaporate, thus leaving the heavier components (e.g., tar), which have traditionally been viewed as less toxic. When oil comes into shallow water and marshes, it can coat and smother resident communities. It can sink below the surface of beaches and marshes and remain there for many years. Oil in marsh sediments undergoes some microbial breakdown but very slowly. Effects of a small oil spill (190,000 gallons of number 2 fuel oil) in Falmouth, Massachusetts, in the late 1960s lasted for over a decade, according to Sanders et al. (1980).
