We consider lifted importance sampling (LIS), a previously proposed approximate inference algorithm for statistical relational learning (SRL) models. LIS achieves substantial variance reduction over conventional importance sampling by using various lifting rules that take advantage of the symmetry in the relational representation. However, it suffers from two drawbacks. First, it does not take ...

This paper analyses the relations between philosophy of information (PI), library and information science (LIS) and social epistemology (SE). In the Ž rst section, it is argued that there is a natural relation between philosophy and LIS but that SE cannot provide a satisfactory foundation for LIS. SE should rather be seen as sharing with LIS a common ground, represented by the study of informat...

Michel Foucault (1926–84) is a primary thinker informing the construction of a critical theory of library and information science (LIS), or librarianship. He is widely cited and is adapted in various ways that focus on LIS forms of power, discourse, and so on. Others have addressed Foucault’s topics, but he remains central. Librarianship has taken up a prior challenge to more fully explore his ...

We measured seasonal variations in microzooplankton grazing in Long Island Sound (LIS) and San Francisco Bay (SFB). There was consistent evidence of nutrient limitation in LIS, but not SFB. We found higher chlorophyll a concentrations in LIS compared with SFB. In spite of differences in phytoplankton, there were no differences in microzooplankton abundance (summer: LIS, 12.4±1.8×10 indiv.L; SFB...

After introductory remarks on the definition of marketing, the evolution of library and information services (LIS) marketing is explained. The authors then describe how marketing was applied to LIS over the years. Marketing is also related to other concepts used in the management of LIS. Finally the role of professional associations in diffusing marketing theory is portrayed and the importance ...

Fifty five planetary nebulae containing micro-structures of low-ionization (LIS) are analyzed in this review in terms of LIS morphology, kinematics, and physical and excitation properties. We attempt to address the issue of their origin through the comparison of LIS properties with the main shells of the nebulae, as well as the contrast with the theoretical model predictions. We finally conclud...

Planktonic and benthic dO records adjacent to the runoff outlets of the Laurentide Ice Sheet (LIS) indicate that the LIS contributed to the abrupt w20 m rise in sea level w14.6 ka, Meltwater Pulse 1A (MWP-1A). However, the magnitude of the LIS contribution still remains unresolved. Here, I use a freshwater runoff–ocean mixing model to calculate the LIS meltwater required to explain the decrease...

PURPOSE To assess changes of the light increment sensitivity (LIS) of the macular area in patients with type 2 idiopathic macular telangiectasia (IMT). METHODS Fifty-eight eyes of 30 patients were examined in a cross-sectional study. All eyes were assigned to group A (early disease stages) or group B (late disease stages with retinal pigment clumping or vascular membranes). Investigation of v...

Purpose: This paper analysis if and how far Library and Information Services (LIS) are supporting E-Science and Grid-Computing projects funded by authorities in the EU and Germany. It explains and emphasises the relevance of LIS based information services and knowhow in e-Science activities. Design/methodology/approach: Projects are analysed regarding how far LIS expertise of institutions or pe...

Internationalisation in Library and Information Science (LIS) education, is becoming a key issue for LIS higher education in Europe. The Bologna process framework means the government support for putting together best educational experiences and expertise of European LIS schools. European Commission higher education programs (SOCRATES, TEMPUS and ERASMUS) could provide adequate financement for ...
