This talk concerns the copula system in Buli, a Ghanaian language which has also been attested in Bahia (Rodrigues 1935, Zwernemann 1968). Special focus will be put on the categorization of two copula-reminiscent elements for which I will propose a discoursepragmatic analysis.
The present study poses the question on what phonetic and phonological grounds postalveolar fricatives in Polish can be analyzed as retroflex and whether postalveolar fricatives in other Slavic languages are retroflex as well. Velarization and incompatibility with front vowels are introduced as articulatory criteria for retroflexion, based on crosslinguistic data. According to these criteria, Polish and Russian have retroflex fricatives, whereas Bulgarian and Czech do not. In a phonological representation of these Slavic retroflexes, the necessity of perceptual features is shown. Lastly, it is illustrated that palatalization of retroflex fricatives both in Slavic languages and more generally causes a phonetic and phonological change to a non-retroflex sound.
On the basis of perceptual experiments we show that alveolo-palatal fricatives and palatalized post-alveolars are two separate sounds which are distinguished not only by Polish native speakers but also by German ones. This claim is partly attested by centre of gravity measurements of the two sibilants. In this paper we revise the claim made by Halle & Stevens [1] and Maddieson & Ladefoged [2] that the Polish alveolo-palatal fricatives [˛, ¸] are palatalized postalveolars [SJ, ZJ]. On the basis of perceptual experiments we show that alveolo-palatal fricatives and palatalized post-alveolars are two separate sounds which are distinguished not only by Polish native speakers but also by German ones. This claim is partly attested by centre of gravity measurements of the two sibilants.
There is little doubt that Quantumchromodynamics (QCD) is the theory which describes strong interaction physics. Lattice gauge simulations of QCD predict that in the m,T plane there is a line where a transition from confined hadronic matter to deconfined quarks takes place. The transition is either a cross over (at low m) or of first order (at high m). It is the goal of the present and future heavy ion experiment at RHIC and FAIR to study this phase transition at different locations in the m,T plane and to explore the properties of the deconfined phase. It is the purpose of this contribution to discuss some of the observables which are considered as useful for this purpose.
Dutch has a three-way contrast in labiodental sounds, which causes problems for native speakers of German in their acquisition of Dutch, since German contrasts only two labiodentals. The present study investigates the perception of the Dutch labiodental fricative system by German L2 learners of Dutch and shows that native Germans with no or little knowledge of the Dutch language categorize the Dutch labiodental voiced fricative and approximant as their native voiced fricative. Advanced learners, however, succeed in acquiring a category for the voiced fricative, illustrating that plasticity in the perception of a second language develops with the amount of exposure to the language.
Experimental data shows that adult learners of an artificial language with a phonotactic restriction learned this restriction better when being trained on word types (e.g. when they were presented with 80 different words twice each) than when being trained on word tokens (e.g. when presented with 40 different words four times each) (Hamann & Ernestus submitted). These findings support Pierrehumbert’s (2003) observation that phonotactic co-occurrence restrictions are formed across lexical entries, since only lexical levels of representation can be sensitive to type frequencies.
A common topic in recent literature on phonology is the question of whether phonological processes and segments are licensed by prosodic position or by perceptual cues. The former is the traditional view, as represented by e.g. Lombardi (1995) and Beckman (1998), and holds that segments occur in specific prosodic positions such as the coda. In a licensing by cue approach, as represented by Steriade (1995, 1999), on the other hand, segments are assumed to occur in those positions only where their perceptual cues are prominent, independent of the prosodic position. In positions where the cues are not salient, neutralization occurs.
Research on a variety of structurally different languages suggests that information is assigned to grammatical form in way of preferred representations of arguments. These preferences can be captured by four interacting constraints which are based on the analysis of spoken and written discourse. These constraints represent measurable discourse preferences: pragmatically unmarked utterances seem to follow them blindly and widely. Consequently, the preferences motivating these constraints seem to represent the default structuring of discourse in immediate relation to elementary grammatical form. Discourse is no longer viewed as acting upon grammatical form, but as being ‘grammatical’ itself.
The objective of this paper is to test the hypothesis that in particular financially constrained firms lease a higher share of their assets to mitigate problems of asymmetric information. The assumptions are tested under a GMM framework which simultaneously controls for endogeneity problems and firms' fixed effects. We find that the share of total annual lease expenses attributable to either finance or operating leases is considerably higher for smaller firms with higher average interest rates and high-growth firms - those likely to face higher agency-cost premiums on marginal financing. Furthermore, our results confirm the substitution of leasing and debt financing for lessee firms. However, we find no evidence that firms use leasing as an instrument to reduce their tax burdens.

Guess how?
(1996)
This paper advances a purely presuppositional analysis of intonation. I first show that a inspiring recent article by Geurts and van der Sandt (Theoretical Linguistics, 2004) that pursues the same goal cannot account for multiple foci. Then, I show that if it is assumed that destressed rather than focussed material is semantically marked, multiple foci are accounted for correctly.
A new semantics for number

Evaluating phonological status : significance of paradigm uniformity vs. prosodic group effects
(2007)
A central concern of linguistic phonetics is to define criteria for determining the phonological status of sounds or sound properties observed in phonetic surface form. Based on acoustic measurements we show that the occurrence of syllabic sonorants vs. schwa-sonorant sequences in German is determined exclusively by segmental and prosodic structure, with no paradigm uniformity effects. We argue that these findings are consistent with a uniform representation of syllabic sonorants as schwa sonorant sequences in the lexicon. The stability of schwa in CVC-suffixes (e.g. the German diminutive suffix -chen), as opposed to its phonetic absence in a segmentally comparable underived context, is argued to be conditioned by the prosodic organisation of such suffixes external to the phonological word of the stem.
Düsseldorf is the capital of North Rhine-Westphalia, the state with the highest number of inhabitants in Germany. The city has a rich cultural history: The theatre history started in 1485 (the festivities in the context of a princely marriage at Düsseldorf). Theatre historiography marks three great periods for Düsseldorf (Immermann, 1834-1837; Dumont-Lindemann, 1905-1933; Gründgens, 1947-1955). The city has a long history of involvment with film, too. For instance the first German film journal „Der Kinematogaph“ began publishing here in 1907. Düsseldorf became after 1945 a distribution center and served for decades as site of all major German and foreign distributors‘ headquartes. It offers still a lot of cultural events: performing arts in different forms (theatre at the Düsseldorfer Schauspielhaus, musical at the Capitol, opera and ballet at the German Opera Düsseldorf-Duisburg, dance at the Tanzhaus (Dance House) North Rhine-Westphalia, free and independant theatre groups, private theatres, cinema, media, museums, cultural institutions, representing other countries like France, Poland ...

Sie wurde von der Universitätsbiblithek Johann Christian Senckenberg in Zusammanarbeit mit dem Deutschem Architektur Museum (Frankfurt am Main) und der Akademie der Architekten- und Stadtplanerkammer Hessen (Wiesbaden) organisiert Das 8. Frankfurt Symposium stellt den zeitgenössischen Bibliotheksbau, die Entwicklungen und die Probleme des gegenwärtigen Bibliotheksbaus zur Diskussion. Einige theoretische und technische Beiträge runden das Programm ab. Zwei zentrale Schwerpunkte des Symposiums werden die Einbindung von Bibliotheksbauten in das Stadtumfeld und die Auswirkungen gesellschaftspolitischer und technischer Entwicklungen auf die Architektur von Bibliotheken sein.
This paper provides an analysis of an alternative strategy to A´-movement in both German and Dutch where the extracted constituent is preceded by a preposition and a coreferential pronoun appears in the extraction site. The construction has properties of both binding and movement: Whereas reconstruction effects suggest movement out of the embedded clause, there is strong evidence that the operator constituent is linked to an A-position in the matrix clause; this paradox is resolved by assuming a Control-like approach that involves movement from the embedded clause into a theta-position in the matrix clause with subsequent short A´- movement. The coreferential pronoun is interpreted as a resumptive heading a Big-DP which hosts the antecedent in its specifier.
Freeze (1992) argued on the basis of data from several different languages that there is a close relationship between existential sentences (stating the existence of an entity) and locative sentences (stating the location of an entity). Freeze (1992) proposes that they are both derived from the same base structure and that the surface differences are rather due to the distinct information structures.This paper argues against this position with the data from Serbian existentials, which show clear syntactic differences from the locatives. Thus, the close relationship between existential and locative sentences that Freeze (1992) observes is conceptual, but not (necessarily) part of the syntax of the language. In order to account for the data, we propose that existential sentences originate from a different syntactic predication structure than the locative ones. The existential meaning arises, as we will show, from the interaction of this predication structure with the structure and meaning of the noun phrase.
Semantic research over the past three decades has provided impressive confirmation of Donald Davidsons famous claim that “there is a lot of language we can make systematic sense of if we suppose events exist” (Davidson 1980:137). Nowadays, Davidsonian event arguments are no longer reserved only for action verbs (as Davidson originally proposed) or even only for the category of verbs, but instead are widely assumed to be associated with any kind of predicate (e.g. Higginbotham 2000, Parsons 2000).1 The following quotation from Higginbotham and Ramchand (1997) illustrates the reasoning that motivates this move: "Once we assume that predicates (or their verbal, etc. heads) have a position for events, taking the many consequences that stem therefrom, as outlined in publications originating with Donald Davidson (1967), and further applied in Higginbotham (1985, 1989), and Terence Parsons (1990), we are not in a position to deny an event-position to any predicate; for the evidence for, and applications of, the assumption are the same for all predicates. (Higginbotham and Ramchand 1997:54)" In fact, since Davidson’s original proposal the burden of proof for postulating event arguments seems to have shifted completely, leading Raposo and Uriagereka (1995), for example, to the following verdict: "it is unclear what it means for a predicate not to have a Davidsonian argument (Raposo and Uriagereka 1995:182)" That is, Davidsonian eventuality arguments apparently have become something like a trademark for predicates in general. The goal of the present paper is to subject this view of the relationship between predicates and events to real scrutiny. By taking a closer look at the simplest independent predicational structure – viz. copula sentences – I will argue that current Davidsonian approaches tend to stretch the notion of events too far, thereby giving up much of its linguistic and ontological usefulness. More specifically, the paper will tackle the following three questions: 1. Do copula sentences support the current view of the inherent event-relatedness of predicates? 2. If not, what is a possible alternative to an event-based analysis of copula sentences? 3. What does this tell us about Davidsonian events? The paper is organized as follows: Section 2 first reviews current event-based analyses of copula sentences and then gives a brief summary of the Davidsonian notion of events. Section 3 examines the behavior of copula sentences with respect to some standard (as well as some new) eventuality diagnostics. Copula expressions will turn out to fail all eventuality tests. They differ sharply from state verbs like stand, sit, sleep in this respect. (The latter pass all eventuality tests and therefore qualify as true “Davidsonian state” expressions.) On the basis of these observations, section 4 provides an alternative account of copula sentences that combines Kim’s (1969, 1976) notion of property exemplifications with Ashers (1993, 2000) conception of abstract objects. Specifically, I will argue that the copula introduces a referential argument for a temporally bound property exemplification (= “Kimian state”). The proposal is implemented within a DRT framework. Finally, section 5 offers some concluding remarks and suggests that supplementing Davidsonian eventualities by Kimian states not only yields a more adequate analysis for copula expressions and the like but may also improve our treatment of events.
A pragmatic explanation of the stage level/individual level contrast in combination with locatives
(2004)
One important difference between stage level predicates (SLPs) and individual level predicates (ILPs) is their behavior with respect to locative modifiers. It is commonly assumed that SLPs but not ILPs combine with locatives. The present study argues against a semantic account for this behavior (as advanced by e.g. Kratzer 1995, Chierchia 1995) and proposes a genuinely pragmatic explanation of the observed stage level/individual level contrast instead. The proposal is spelled out using Blutners (1998, 2000) optimality theoretic version of the Gricean maxims. Building on the observation that the respective locatives are not event-related but frame-setting modifiers, the preference for main predicates that express temporary properties is explained as a side-effect of “synchronizing” the main predicate with the locative frame in the course of finding an optimal interpretation. By emphasizing the division of labor between grammar and pragmatics, the proposed solution takes a considerable load off of semantics.
This paper examines the development of periphrastic constructions involving auxiliary "have" and "be" with a past participle in the history of English, on the basis of parsed electronic corpora. It is argued that the two constructions represented distinct syntactic and semantic structures: while the one with have developed into a true perfect in the course of Middle English, the one with be remained a stative resultative throughout its history. In this way, it is explained why the be construction was rarely or never used in a number of contexts, including past counterfactuals, iteratives, duratives, certain kinds of infinitives and various other utterance types that cannot be characterized as perfects of result. When the construction with have became a true perfect, it was used in such contexts, regardless of the identity of the main verb, leading to the appearance of have with verbs like come which had previously only taken be. Crucially, however, have was not spreading at the expense of be, as the be perfect had never been used in such contexts, but rather at the expense of the old simple past. At least until the end of the Early Modern English period, the shift in the relative frequency of have and be perfects is to be explained in terms of the expansion of the former into new contexts, while the latter remained stable. A formal analysis is proposed, taking as its starting point a comparison with German which shows that the older English be perfect indeed behaves more like the German stative passive than its haben and sein perfects.
Market uptake of pegylated interferons for the treatment of hepatitis C in Europe : meeting abstract
(2008)
Introduction and Objectives Hepatitis C virus (HCV) infection is a leading cause of chronic liver disease with life threatening sequelae such as end-stage liver cirrhosis and liver cancer. It is estimated that the infection annually causes about 86,000 deaths, 1.2 million disability adjusted life years (DALYs), and ¼ of the liver transplants in the WHO European region. Presently, only antiviral drugs can prevent the progression to severe liver disease. Pegylated interferons combined with ribavirin are considered as current state-of-the-art treatment. Objective of this investigation was to assess the market uptake of these drugs across Europe in order to find out whether there is unequal access to optimised therapy. Material and Methods We used IMS launch and sales data (April 2000 to December 2005) for peginterferons and ribavirin for 21 countries of the WHO European region. Market uptake was investigated by comparing the development of country-specific sales rates. For market access analysis, we converted sales figures into numbers of treated patients and related those to country-specific hepatitis C prevalence. To convert sales figures into patient figures, the amount of active pharmaceutical ingredients (API) sold was divided by average total patient doses (ATPD), derived by a probability tree-based calculation algorithm accounting for genotype distribution, early stopping rules, body weight, unscheduled treatment stops and dose reductions Ntotal=APIPegIFNalpha-2a/ATPDPegIFNalpha-2a+APIPegIFN&alpha-2b/ATPDPegIFNalpha-2b For more concise result presentation the 21 included countries were aggregated into four categories: 1. EU founding members (1957): Belgium, France, Germany, Italy and Netherlands; 2. Countries joining EU before 2000: Austria (1995), Denmark (1973), Finland (1995), Greece (1981), Republic of Ireland (1973), Spain (1986), Sweden and UK (1973) 3. Countries joining EU after 2000: Czech Republic (2004), Hungary (2004), Poland (2004) and Romania (2007); 4. EU non-member states: Norway, Russia, Switzerland and Turkey. Results Market launch and market uptake of the investigated drugs differed considerably across countries. The earliest, most rapid and highest increases in sales rates were observed in the EU founding member states, followed by countries that joined the EU before 2000, countries that joined the EU after 2000, and EU non-member states. Most new EU member states showed a noticeable increase in sales after joining the EU. Market access analysis yielded that until end of 2005, about 308 000 patients were treated with peginterferon in the 21 countries. Treatment rates differed across Europe. The number of patients ever treated with peginterferon per 100 prevalent cases ranged from 16 in France to less than one in Romania, Poland, Greece and Russia. Discussion Peginterferon market uptake and prevalence adjusted treatment rates were found to vary considerably across 21 countries in the WHO European region suggesting unequal access to optimised therapy. Poor market access was especially common in low-resource countries. Besides budget restrictions, national surveillance and prevention policy should be considered as explanations for market access variation. Although our results allowed for the ranking of countries in order of market access, no final conclusions on over- or undertreatment can be drawn, because the number of patients who really require antiviral treatment is unknown. Further research based on pan-European decision models is recommended to determine the fraction of not yet successfully treated but treatable patients among those ever diagnosed with HCV. ...
The paper is structured as follows. Section 2.1 introduces the basic classes of adjectives that constitute the factual core of the paper. Section 2.2 summarizes in greater detail the X° and the XP movement approaches to word order variation within the DP. Section 3 briefly discusses problems for both approaches. Sections 4.1, 5.1, and 5.2 draw from Alexiadou (2001) and contain a discussion of Greek DS and its relevance for a re-analysis of the word order variation in the Romance DP. Section 4.2 introduces refinements to Alexiadou & Wilder (1998) and Alexiadou (2001). Section 5.3. discusses certain issues that arise from the analysis of postnominal adjectives in Romance as involving raising of XPs. Section 6 discusses phenomena found in other languages, which at first sight seem similar to DS. However, I show that double definiteness in e.g. Hebrew, Scandinavian or other Balkan languages constitutes a different type of phenomenon from Greek DS, thus making a distinction between determiners that introduce CPs (Greek) and those that are merely morphological/agreement markers (Hebrew, Scandinavian, Albanian).

The fear that with the existence of an unconditional basic income sufficient for living many people would cease to engage in a productive life, would only relax, consume and devote to having fun, can be addressed from different perspectives. One of these is the sociology of religion, which allows elaborating the argument that with such a way of life the question about the meaning of life cannot be answered. But this "meaning question", the whole research within the field of the sociology of religion speaks for this, compellingly must be answered by each life praxis. It cannot remain unanswered, as is said already in the Bible: "Man does not live on bread alone, [but on every word that comes from the mouth of God.]" (5. Moses 8.3, Matthew 4.4, Lukas 4.4) The paper examines the reasons of this fact and its consequences in regard to a life with an unconditional basic income sufficient for living.
Meeting Abstract : 27. Deutscher Krebskongress. Berlin, 22.-26.03.2006.
Docetaxel, Adriamycin, Cyclophosphamide (TAC) is considered today as one treatment option for patients with node-positive primary breast cancer. However, treatment is associated with anaemia grade 1-4 (2-4) in up to 95% (36%) of patients. We prospectively investigated the use of a primary prophylaxis with Darbepoetin alfa once every 3 weeks in 35 patients receiving six to eight cycles of TAC as neoadjuvant treatment for breast cancer. Darbepoetin treatment started on day 1 of a TAC cycle if haemoglobin (Hb) was ≤ 14.0 g/dl. Dosage was adapted to 9 µg/kg if Hb was ≤ 13.0 g/dl on day 21 of the previous cycle, to 4.5 µg/kg if Hb was between 13.0 and 14.0 g/dl and was discontinued if Hb increased to ≥ 14 g/dl. The primary aim was to prevent Hb levels ≤ 12 g/dl before surgery. During 112 (50.2%) and 93 (41.7%) of 223 cycles, 4.5 µg/kg and 9 µg/kg Darbepoetin were given, respectively. Dosage was decreased from 9 to 4.5 µg/kg in 21 (60%) patients and 28 (12.4%) cycles. Treatment was discontinued due to Hb > 14.0 g/dl in 12 (34.3%) patients and 13 (5.4%) cycles. Hb level on day 21 of the last cycle was ≤ 12.0 g/dl in 4 (11.4%) patients. Eighteen (51.4%) patients during 36 (16.1%) cycles showed Hb levels ≤ 12 g/dl throughout treatment. No NCI-CTC grade 2 to 4 anaemia was observed. Symptoms of fatigue (FACT-AN) decreased slightly throughout treatment. Anaemia during TAC chemotherapy can be avoided by a single injection of Darbepoetin alfa every 3 weeks.
In several academic fields (most notably: physics, mathematics, economics, astronomy, and computer science), most current research papers are freely accessible on the Internet in both pre- and post-publication formats. For these disciplines, open-access dissemination of publications and data has created a robust and useful information environment that is highly valued by researchers. While the acceptance of open-access dissemination has been disruptive to traditional scholarly publishing, the status and economic value of the elite journals has remained largely intact. Indeed, publication in the most prestigious journals (e.g., Science, Nature, Cell, BMJ, etc.) may have more influence than ever in determining the advancement of academic careers. Traditional publishing and open access will continue to coexist uncomfortably for years to come, but the next wave of digital publishing systems (empowered social networking applications) will establish open access repositories as indispensable infrastructure for the sciences and social sciences.
University 2.0
(2007)
The major challenge facing universities in the next decade is to reinvent themselves as information organizations. Universities are, at their core, organizations that cultivate knowledge, seeking both to create new knowledge and to preserve and convey existing knowledge, but they are remarkably inefficient and therefore ineffective in the way that they leverage their own information resources to advance that core activity. This talk will explore ways that the university could learn from what is now widely called "Web 2.0" -- a term that is meant to identify a shift in emphasis from the computer as platform to the network as platform, from hardware to data, from the wisdom of the expert to the wisdom of crowds, and from fixity to remixability.
Universities of the 21st century heavily depend on an efficient IT infrastructure for teaching, research and administration. E-Learning environments, blended learning and all sorts of multimedia and cooperative environments are important requirements for teaching at universities and for further education. Many of the organizational structures such as continuous examinations, interdisciplinary studies, ECTS system and many more require efficient examination administration systems as well as room and personnel management. Research is based on Internet inquiries, eScience, eLibrary and other IT supported media. Research results must be documented and archived in a digital way and results must be distributed and marketed through the Internet. The efficient administration of all kinds of resources of the university must be planned using management support systems. Decisions of university heads must be prepared from well documented statistics and analysis software. In the past, many of the applications named above for teaching, research and administration have been performed by separate software applications and run in distributed environments of universities. Powerful server structures and networking features as well as new software technology like service-oriented architectures make it necessary to recentralize the IT services of the university after a long period of decentralization. Based on metadirectories and unified access procedures, all of the software components must be integrated into a seamless IT infrastructure. To guarantee consistency, data must not be stored in a redundant way. Project IntegraTUM of Technische Universität München started in 2003 and is an umbrella project to define such a seamless IT infrastructure for a university with 22.000 students and approximately 10.000 staff. The talk describes the project, which besides the definition of new technology is based on a fundamental process analysis of the university and many changes in the organizational structure.
Working closely with teaching and research staff is critical to the success of libraries and information services. Indeed, the degree of integration with a University's academic work is one of the factors that distinguish a successful service from a poor one. This paper will consider the relationship between information services and how universities operate. Using the challenges facing institutions as a starting point - including the move towards a single European higher education market - the impact of information provision on institutional strategies will be explored. Information resources underpin all learning, teaching and research activities and the presentation will consider the professional practice which ensures that libraries and computing services are fully exploited. The focus on the experience of students is leading some institutions to integrate information services with a wide range of other activities and the paper will consider the opportunities and challenges which this brings, including the need to build working relationships with a broader range of professional groups.
Trends for distributed, open, and increasingly collaborative models of information delivery challenge the library's classic roles. In addition, trends within the research community for more interdisciplinary and collaborative scholarship create an opportunity for more enabling information infrastructure. In an age of Amazon, Google, and "social" tools, how should the library respond? My presentation will focus on strategies for bringing the library's "assets" into the flow of researchers' work. How can the library integrate its resources into the scholar's workflow? What are the emerging challenges of this integration?
Information supply is the genuine task of academic institutions as well as of publishers. Publishers profit from copyright provisions which give them exclusive rights in their products. The same copyright provisions are often the limiting factor when academic institutions try to improve their service to the academic community. This is the case in particular when it comes to digital access to information. In a so-called "Second Basket", the German copyright act has just been revised, introducing explicit legal exemptions for document deliveries and on the spot consultation of works contained in public libraries' collections. At the same time, unresolved issues remain with respect to existing legal exemptions as well as the new ones. What will the legal parameters look like for academic institutions once the "Second basket" has been put into force? How can libraries work with these provisions in practice?
Information Supply in the era of mass digitization Drawing on his experience at the Bodleian Library and now at the British Library, Ronald Milne will share his first-hand impressions of 'boutique' and mass digitization programmes, such as those being undertaken by Google and Microsoft, and their effect on information supply. Collections define libraries. What does this mean in the 21st Century? Will all libraries become equal as the digital revolution progresses? What might the digitization and indexing of millions of works mean for university researchers and the intellectually curious more generally? What are the benefits and what are the strategic issues that we are bound to consider?
Rather than introducing a new system for global identity management, the University of Freiburg decided to continue with the existing software systems (esp. from HIS), to identify the leading system for each set of data and to mirror the data between the various systems. A clearly defined workflow ensures that changes to data are made only on the relevant "leading" system and then propagated to the other systems. User authentication for systems managed by the computer center is done via LDAP. Consequently, while access rights are granted by the LDAP system, the decision of whether or not the person is a member of the University is left to the administration. As a consequence the implementation of a portal called mylogin to get the necessary tickets for shibboleth is a straightforward process as it only remains to check the data against LDAP before issueing the corresponding tickets.
The aim of the meeting is to expose this current topic for critical discussion with international speakers and participants and to find solutions which optimize the integration of information services into university structures. Presentations and discussions will consider: * integrated versus cooperative models * single-unit operations, central or de-centralized faculty organisations * outsourcing services versus own organisation/effort * institutional repository versus discipline-based repository * information supply in the era of "Google print" »The Integration of Information Services into University Structures« Symposium will be taking place simultaneously with the Frankfurt Book Fair, the largest book-related event in the world attracting annually 286,621 people (2006) , thus giving participants who arrive early the chance to combine attendance at both the Book Fair and Symposium. A cultural event and dinner in one of Frankfurt's historical rooms on Friday will be a social highlight! A contingency of hotel rooms has been reserved on a »first come, first served basis« outside Frankfurt at non-Book Fair prices. More information on request.
The mission of the Harvard Judaica Collection is to comprehensively document Jewish history and civilization in all places and periods. To accomplish its mission, the Judaica Collection collects materials in all languages and in all formats—books, pamphlets, periodicals, newspapers, sound recordings, and videos, posters, broadsides, and photographs. A particular focus is the Library’s Documenting Israel program, which covers all aspects of Israeli life and culture in great depth; Harvard has the largest collection of Israeli publications and Israel-related materials outside the State of Israel. The Harvard Judaica Collection also attempts to have comprehensive coverage of the publications of Jewish communities throughout the globe, including a significant collection of publications from countries across Europe. Collecting these materials requires cooperation with a wide array of institutions and individuals around the world.
The LOCKSS (Lots of Copies Keep Stuff Safe) Alliance is an international community of about 100 libraries and partners like OCLC. For almost a decade the LOCKSS open source model has been tested for its robustness against attack and for its ability to migrate formats. LOCKSS »boxes« at 150 institutions in more than 20 countries comprise a peer-to-peer system that automatically cross-checks content to ensure the accuracy and completeness of all member archives. Eighty publishers, including large publishers like Oxford University Press, are now participating in LOCKSS or actively preparing to add their journals to the program.
U. S. library resources on South Asia that were built around the limited needs of a handful of Sanskritics before World War II have made a long journey during the past half century. Since the inception of the Library of Congress Cooperative South Asia Acquisition Program (formerly called "PL-480" program), in 1962, libraries have built significant collections with financial support from governmental agencies and philanthropic foundations, to support teaching and research in all areas of social sciences and humanities. These collections have been supplemented by efforts to build retrospective collections and to microfilm rare materials in British and South Asian libraries and archives. Today, in cooperation with South Asian libraries, several projects are underway to preserve and digitize rapidly deteriorating materials so that these riches can be shared with the global scholarly community through electronic means.
To stimulate further discussion, I would like to briefly tackle the following questions: * How can one become informed about what is going on in German Studies in the US? * What kinds of American guides to German resources are available? * What kinds of German Studies resources are being produced in the US? * What do we know about how scholars are using (or not) these guides and resources?
The enhancing importance of digital documents has effected activities on how to deal with them. One line came from the more general field of "scientific publishing", which was handled in detail by DINI (Deutsche Initiative für Netzwerkinformation). But for this initiative long- time archiving was only one field of many and was not their primary focus. DINI first of all concentrated on the elaboration of effective and standardized methods and tools for publishing and related services on the basis of open access policy via the use of institutional repositories. The second line of projects came from the more general view of maintaining cultural heritage also in a digital world. Especially under the patronage of the Ministry of Education and Research important projects were being financed. Strategic solutions including archives, libraries, and museums are discussed and elaborated within NESTOR, where more technical solutions based on the term of practicability are developed within KOPAL. KOPAL brought together the industry (IBM) with a public- funded technical center (GWDG) and two libraries (DNB and SUB Göttingen). Within this project a general software implementation, which took into consideration all necessary international standards, could be finished last month and has been now for about two weeks. Based on early results within NESTOR it seemed important too, to strengthen all activities by giving them a legal basis. Therefore when the law changed concerning the German National Library from June 22nd this year (DNBG), the library was authorized with all the necessary instruments to collect digital documents in "non-physical" form as well. With this law at the moment Germany is in the rare position of being one of the few countries where the collection of network publications is part of the whole legal deposit strategy.
In the year 2000 the Deutsche Initiative für Netzwerkinformation (DINI) / German Coalition of Network Information was founded: 10 theses "Changes in information infrastructure – challenges to universities and their information and communications facilities" is the DINI’s founding charter (s. http://www.dini.de).
Thesis 4 states: "The universities need to establish information management structures to integrate departments. University managements, departments and central institutions ought to prepare a university development plan for the areas of information, communication and multimedia." ...
Background and Purpose of this Meeting With an opening reception sponsored by Thomson Scientific on the evening of Thursday, October 5, the University Library of Frankfurt and the German-North American Resources Partnership (GNARP) and will be hosting an important two-day conference this Autumn in Frankfurt, Germany: »The World According to GNARP: Prospects for Transatlantic Library Partnership in the Digital Age« Sessions at this meeting will explore the wealth of library resources - archival, print, and digital - available to students and researchers (in Germany and the United States) in five selected subject areas: North American Studies, German Studies, Judaica, Africana, and South Asia/India, highlighting both existing avenues (and obstacles) for transatlantic resource sharing along with future prospects. In addition, several other important topics will be highlighted through individual presentations and panel discussions: the future of German as a language of the sciences; existing and planned electronic journal archives in Germany and the U.S.; print and digital repositories; and a special panel on »comparative cataloging cultures« on both sides of the Atlantic. The »World According to GNARP« conference will be taking place simultaneously with the Frankfurt Book Fair, the largest book-related event in the world, attracting annually 285,000 visitors (2005), thus giving participants who arrive early the chance to combine attendance at both the Book Fair and Conference. A cultural event and dinner in Frankfurt are planned for Friday 6th October.
The Frankfurt University Library possesses one of the outstanding Africana Collections in continental Europe; its regional anddisciplinary scope is unique in Germany. Today about 5,000 new acquisitions a year have accumulated over 200,000 items on Africa south of the Sahara. Some 50,000 historical and rare photographs are fully digitized and freely accessible. Together with a collection of around 18,000 books stemming from the collections of the German Colonial Society at the end of the 19th and the beginning of the 20th century they constitute the historical foundations of the collection. Recently the University Library Frankfurt and the library of the GIGA Institute of African Affairs, Hamburg, started the project ilissAfrica (internet library sub-Saharan Africa), a central subject gateway for online resources and a powerful tool for bibliographic research. These new services will be indispensable for researchers and librarians of African Studies and will promote African studies worldwide.
We discuss the present collective flow signals for the phase transition to quark-gluon plasma (QGP) and the collective flow as a barometer for the equation of state (EoS). A study of Mach shocks induced by fast partonic jets propagating through the QGP is given. We predict a significant deformation of Mach shocks in central Au+Au collisions at RHIC and LHC energies as compared to the case of jet propagation in a static medium. Results of a hydrodynamical study of jet energy loss are presented.
Background and Aim: In Germany, the discharge medication is usually reported to the general practitioner (GP) by an inital short report (SR) /notification (handed over to the patient) and later by a more detailed discharge letter (DL) of the hospital.
Material and Method: We asked N=536 GPs (from Frankfurt/Main and Luebeck) after the typical report format of their patients discharge medication by the local hospitals. The questionnaire asked for 26 items covering (1) the designation of the medication (brand name, generic name) in SR and DL, (2) further specifications e.g. possibilities of generic substitution or supervision of sensible medications, (3) reasons why GPs do not follow the hospitals recommendations and (4) possibilities for an improvement in the medication-related communication between GP and hospitals.
Results: 39% GPs responded sufficiently to the questionnaire. The majority of the GPs (82%) quoted that in the SR only brand names are given (often or ever) and neither the generic name or any further information on generic substitution is available (seldom or never). 65% of the responders quoted that even in the DL only brand names are given. Only 41% of the responders quoted that further treatment relevant specifications are given (often or ever). 95% responded that new medications or change of custom medication is seldom or never explained in the DL and GP were not explicitly informed about relevant medication changes. 58% of the responders quoted economic reasons for re-adjustment of the discharge medication e.g. by generic substitution. The majority of responders (83%) are favouring (useful or very useful) a pre-discharge information (e.g. via fax) about the medication and 54% a hot-line to some relevant person in the hospital when treatment problems emerge. 67% of the responders quoted in favour of regular meetings between GPs and hospital doctors regarding actual pharmacotherapy.
Conclusion: In conclusion, our survey pointed to marked deficiencies in reporting the discharge medication to GPs.
Conflict of interest: None
Background The detection of the new Coranavirus (CoV) causing agent of the severe acute respiratory syndrome (SARS) for diagnostic purposes is still a critical step in prevention of secondary hospital infections. In this respect the PCR for SARS diagnostic is the fastest and most sensitive method and was published very early after the description of the new pathogen by different groups. To evaluate the quality and sensitivity of the SARS PCR performed in diagnostic laboratories all over the world an external quality assurance (EQA) for SARS PCR was initiated by the WHO, the European Network for Diagnostics of "Imported" Viral Diseases (ENIVD) and the Robert Koch-Institut. Methods Therefore 10 samples of inactivated SARS CoV strains isolated in Frankfurt and Hong Kong in different dilutions and negative controls were prepared. The freeze dried samples were send by mail to 62 different laboratories, in 37 countries in Europe and Israel (35), Asia (11), The Americas (11), Australia and New Zealand (4) and Africa (1). The results were returned by email or fax 1 week (13), 2 weeks (14), 3 weeks (6) and later (29) after receiving the material which does not mimic at all the possible speed of this fast method. But this was not considered in the evaluation of these first SARS EQA. Results 44 laboratories showed good or excellent results (26 = 100%, 18 = 90%) and even the 14 laboratories which archived only 80% (10) or 70% (4) correct results are mostly lacking sensitivity. The results of the other 4 laboratories show basic problems in regard to sensitivity, specificity and consistency of results and must be overcome as soon as possible. 4 laboratories seem to have problems with the specificity finding a positive signal in negative samples. The different methods used for preparation of the SARS CoV genome and diagnostic PCR test procedure used by the participating laboratories will be discussed in more detail in the presentation. Conclusion However, in contrast to previous EQAs for Ebola, Lassa and Orthopoxviruses the quality of PCR results was rather good which might be caused by the early publication and distribution of well developed PCR methods. An EQA for evaluation of SARS specific serology is still ongoing, first results will be available beginning of April 2004.
Objective: Establishment of an immunocompetent mouse model representing the typical progressive stages observed in malignant human gliomas for the in vivo evaluation of novel target-specific regimens.
Methods: Isolated clones from tumours that arose spontaneously in GFAP-v-src transgenic mice were used to develop a transplantable brain tumour model in syngeneic B6C3F1 mice. STAT3 protein was knocked down by infection of tumour cells with replication-defective lentivirus encoding STAT3-siRNA. Apoptosis is designed to be induced by soluble recombinant TRAIL + chemical Bcl-2/Bcl-xL inhibitors.
Results: Striatal implantation of 105 mouse tumour cells resulted in the robust development of microscopically (2 – 3 mm) infiltrating malignant gliomas. Immunohistochemically, the gliomas displayed the astroglial marker GFAP and the oncogenic form of STAT3 (Tyr-705-phosphorylated) which is found in many malignancies including gliomas. Phosphorylated STAT3 was particularly prominent in the nucleus but was also found at the plasma membrane of peripherally infiltrating glioma cells. To evaluate the role of STAT3 in tumour progression, we stably expressed siRNA against STAT3 in several murine glioma cell lines. The effect of STAT3 depletion on proliferation, invasion and survival will be first assessed in vitro and subsequently after transplantation in vivo. Upstream and downstream components of the STAT3 signalling pathway as well as possible non-specific side effects of STAT3-siRNA expression after lentiviral infection will be examined, too.
Conclusions: Its high rate of engraftment, its similarity to the malignant glioma of origin, and its rapid locally invasive growth should make this murine model useful in testing novel therapies for malignant gliomas.
This paper presents the design and implementation of a group oriented, decentralised, virtual learning settings where students meet in groups of 3 –5 people at different locations all over the world and communicate via the internet. After presenting the objective of such a didactical design the paper gives an insight into the technical implementation. It presents the advantages and disadvantages of several internet services in such a virtual setting and a way of combining these internet applications according to their special characteristics. While the role of teachers change to those of coordinators the communication process within and between the groups becomes more important – as discussed in the following chapter. The paper concludes with the presentation of two practical applications as offered by the Institute for Didactics and Economics at the Johann Wolfgang Goethe-University Frankfurt/Main (Germany) and some evaluating remarks.
The University library in Frankfurt/Main owns the largest collection of literature on Judaism and Israel in Germany and one of the major collections in the world. Its task is to document the history of the Jewish people and to serve as a resource for study and research in Germany. The Jewish Division is therefore collecting all relevant national and international publications covering all aspects of post-biblical Judaism and Jewish culture in a most comprehensive manner, as well as all publications on the modern State of Israel. Two databases offer access to the large collections of the Judaica-Division. Yiddish Literature is the database that offers online access to the page images of the outstanding historical Yiddish collection, containing about 800 extremely rare and precious Yiddish and German-Jewish books printed in Hebrew letters from the 16th century onwards. Compact memory is a gateway to more than 100 Jewish periodicals in the German language area published in the 19th and 20th century, providing partly images, partly full-text-search and a bibliographic database of articles. The implementation of a third, new digital project, the »Virtual Judaica-collection« has just started - the digitization and online-presentation of the historical Judaica resources. Formed by his curator Prof. Aron Freimann, it was the largest and most significant Judaica collection on the European continent before the war. The goal is to offer free access to about 18.000 books with 2 Mill. pages over the web. In light of these developments, the presentation will evaluate the current possibilities of German-North-American cooperation in the area of digital projects.
A number of pressures on academic libraries imperil the long-term survivability of printed knowledge and heritage materials. Ever-growing volumes of materials, costs of preserving and delivering paper-based research resources, and researchers’ growing demand for source materials in electronic formats all produce strain on our institutions. ...
Despite a legal framework being in place for several years, the market share of qualified electronic signatures is disappointingly low. Mobile Signatures provide a new and promising opportunity for the deployment of an infrastructure for qualified electronic signatures. We that SIM-based signatures are the most secure and convenient solution. However, using the SIM-card as a secure signature creation device (SSCD) raises new challenges, because it would contain the user’s private key as well as the subscriber identification. Combining both functions in one card raises the question who will have the control over the keys and certificates. We propose a protocol called Certification on Demand (COD) that separates certification services from subscriber identification information and allows consumers to choose their appropriate certification services and service providers based on their needs. This infrastructure could be used to enable secure mobile brokerage services that can ommit the necessity of TAN lists and therefore allow a better integration of information and transaction services.
Seit 2005 ist die Bibliothek des Südasien-Instituts in Kooperation mit der UB Heidelberg Trägerin des DFG-geförderten Sondersammelgebiets Südasien. Damit hat sie von der UB Tübingen ein traditionsreiches Sondersammelgebiet übernommen, dessen Geschichte bis ins Jahr 1949 zurückreicht. Der Vortrag wird zum Einen einen kurzen Überblick über den historischen Kontext des SSG Südasien geben und zum Anderen über Neuentwicklungen, wie z.B. die Virtuelle Fachbibliothek Südasien, die in den letzten zwei Jahren an der Bibliothek des Südasien-Instituts aufgebaut wurde. Vor diesem Hintergrund soll vor allem das Kooperationspotential im Bereich digitaler Informationsressourcen beleuchtet werden.
The paper will provide a brief background to the history of the organization and cooperative efforts of African studies librarians in the United States including their efforts at international cooperation. Particular emphasis will be placed on the current opportunities for improved cooperation as digitization activities increase. Examples will include the DISA and Aluka initiatives and well as the Timbuktu manuscript digitization project at the Center for Research Libraries. Particular emphasis will placed on the possibilities for German-North American cooperation in the area of digital projects of historical photographs given the extensive collections held at Northwestern and Frankfurt.
... This year's Scientific Symposium of the University Library is already number six in the row. It was again prepared and organised like some of the previous conferences together with our North American partners. This means that a continuous specialists’ discussion and a professional partnership have been already installed. All librarians and information managers are invited to learn more about the results of this cooperation every year when it's time for the next Symposium during Frankfurt Book Fair. ...
Large American research libraries have been acquiring - by purchase and by lease - huge multi-disciplinary electronic collections of primary and secondary source materials. For example, the Digital Evans and Canadian Poetry easily make available to scholars primary materials that once were scattered in libraries across North America and Europe. The American State Papers, 1789 – 1838 collection allows easier searching of fragile rare materials. Collections made by libraries digitizing their own holdings, such the Archive of Early American Images from the John Carter Brown Library at Brown University, make research materials more discoverable and usable. Yet recent scholarship in American Studies by American and European scholars makes relatively little use of these new materials. Both disparities and congruities in what scholars use and what research libraries collect are apparent. Some simple reasons explain the dissonance. Furthermore, conversations with scholars suggest that materials and collections alone will not suffice to support research. Librarians’ skills and actions will increase the value of the new research materials.
The paper presents an overview about some of the international relevant projects of digital resources in Germany. Online presentations of primary sources, e.g. photographic material, and bibliographic tools supporting research, such as cross searching, will be presented as potential partners of resource sharing with North America. Not only the possibility of cooperation will be sketched, but also necessary preliminary work and some obstacles will be outlined. This report is accompanied by a short characterization of African studies in Germany and the status quo of Open Access-initiatives.
Retiming is a widely investigated technique for performance optimization. It performs powerful modifications on a circuit netlist. However, often it is not clear, whether the predicted performance improvement will still be valid after placement has been performed. This paper presents a new retiming algorithm using a highly accurate timing model taking into account the effect of retiming on capacitive loads of single wires as well as fanout systems. We propose the integration of retiming into a timing-driven standard cell placement environment based on simulated annealing. Retiming is used as an optimization technique throughout the whole placement process. The experimental results show the benefit of the proposed approach. In comparison with the conventional design flow based on standard FEAS our approach achieved an improvement in cycle time of up to 34% and 17% on the average.
Retiming is a widely investigated technique for performance optimization. In general, it performs extensive modifications on a circuit netlist, leaving it unclear, whether the achieved performance improvement will still be valid after placement has been performed. This paper presents an approach for integrating retiming into a timing-driven placement environment. The experimental results show the benefit of the proposed approach on circuit performance in comparison with design flows using retiming only as a pre- or postplacement optimization method.
This paper presents a new timing driven approach for cell replication tailored to the practical needs of standard cell layout design. Cell replication methods have been studied extensively in the context of generic partitioning problems. However, until now it has remained unclear what practical benefit can be obtained from this concept in a realistic environment for timing driven layout synthesis. Therefore, this paper presents a timing driven cell replication procedure, demonstrates its incorporation into a standard cell placement and routing tool and examines its benefit on the final circuit performance in comparison with conventional gate or transistor sizing techniques. Furthermore, we demonstrate that cell replication can deteriorate the stuck-at fault testability of circuits and show that stuck-at redundancy elimination must be integrated into the placement procedure. Experimental results demonstrate the usefulness of the proposed methodology and suggest that cell replication should be an integral part of the physical design flow complementing traditional gate sizing techniques.
We present new concepts to integrate logic synthesis and physical design. Our methodology uses general Boolean transformations as known from technology-independent synthesis, and a recursive bi-partitioning placement algorithm. In each partitioning step, the precision of the layout data increases. This allows effective guidance of the logic synthesis operations for cycle time optimization. An additional advantage of our approach is that no complicated layout corrections are needed when the netlist is changed.
The languages of the world differ with respect to argument extraction possibilities. In languages such as English, wh-movement is possible from Spec IP and from the complement position, whereas in languages such as Malagasy only extraction from Spec IP is possible. This difference correlates with the fact that these language types obey different island constraints and behave differently with respect to wh-in situ and superiority effects. The goal of this paper is to outline an analysis for these differences. The basic idea is that in contrast to languages such as English, in Malagasy-type languages every argument can be merged in the complement position of the selecting head.
Expletives as features
(2000)
Expletives have always been a central topic of theoretical debate and subject to different analyses within the different stages of the Principles and Parameter theory (see Chomsky 1981, 1986, 1995; Lasnik 1992, 1995; Frampton and Gutman 1997; among others). However, most analyses center on the question how to explain the behavior of expletives in A-chains (such as there in English or Þad in Icelandic). No account relates wh-expletives (as one finds them in so-called partial wh-movement constructions in languages such as Hungarian, Romani, and German) to expletives in Achains. In this paper, I argue that the framework of the Minimalist Program opens up the possibility of accounting for expletive-associate relations in A-/A'-chains in a unified manner. The main idea of the unitary analysis is that an expletive is an overtly realized feature bundle that is (sub)extracted from its associate DP. There in an expletive-associate chain is a moved D-feature which orginates inside the associate DP. Similarily, in A'-chains, the whexpletive originates as a focus-/wh-feature in the wh-phrase with which it is associated. This analysis provides evidence for the feature-checking theory in Chomsky (1995). The paper is organized as follows. Section 2 contains the discussion of expletive there. In section 3 I suggest an analysis for whexpletives, and I also explore whether this analysis can be extended to relations between X°-categories such as auxiliary and participle complexes.
In this paper I show that Clitic Climbing (CC) in Spanish and Long Scrambling (LS) in German (and Polish) are (im-)possible out of the same environments. For an explanation of this fact I propose a feature-oriented analysis of incorporation phenomena. The idea is that restructuring is a phenomenon of syntactic incorporation. In German and Polish, Agro incorporates covertly into the matrix clause and licenses LS out of the infinitival into the matrix clause. Similarily the clitic in Spanish, which is analysed as an Agro-head, incorporates into the matrix clause. I argue that this movement is necessary for reasons of feature-checking, i. e. for checking of an [+R]- or Restructuring-feature. In section 2 I discuss several differences between CC and LS. For example, the proposed analysis correctly predicts that clitics in contrast to scrambled phrases are subject to several serialization restrictions. Throughout the paper I use the term restructuring only in a descriptive sense, in order to describe the phenomenon in question.
Flight paths of homing pigeons were measured with a newly developed recorder based on GPS. The device consists of a GPS receiver board, a logging facility, an antenna, a power supply, a DCDC converter and a casing. It has a weight of 33g and works reliably with a sampling rate of 1/s with an operation time of about 3 h, providing timeindexed data on geographic positions, ground speed and altitude. The data are downloaded when the bird is recaptured. The devices are fixed to the birds with a harness. The measured complete flight paths show many details: e.g. initial loops flown immediately after release and large detours flown by some pigeons. We are here presenting 3 examples of flight paths from a release site 17.3 km Northeast of the home loft in Frankfurt. Mean speed in flight, duration of breaks and length of the flight path were calculated. The pigeons chose different routes and have different individual tendencies to fly loops over the village close to the release site.
This paper describes a first version of the GPS flight recorder for homing pigeons. The GPS recorder consists of a hybrid GPS board, a patch antenna 19*19 mm, a 3 V Lithium battery as power supply, a DCDC converter, a logging facility and an additional microprocessor. It has a weight of 33g. Prototypes were tested and worked reliably with a sampling rate of 1/sec and with an operation time of about 3 h. In first tests on homing pigeons 9 flight paths were recorded, showing details like loops flown immediately after the release, complete routes over 30 km including detours, rest periods and speed.
Location-based services (LBS) are services that position your mobile phone to provide some context-based service for you. Some of these services – called ‘location tracking’ applications - need frequent updates of the current position to decide whether a service should be initiated. Thus, internet-based systems will continuously collect and process the location in relationship to a personal context of an identified customer. This paper will present the concept of location as part of a person’s identity. I will conceptualize location in information systems and relate it to concepts like privacy, geographical information systems and surveillance. The talk will present how the knowledge of a person's private life and identity can be enhanced with data mining technologies on location profiles and movement patterns. Finally, some first concepts about protecting location information.
Mobile telephony and mobile internet are driving a new application paradigm: location-based services (LBS). Based on a person’s location and context, personalized applications can be deployed. Thus, internet-based systems will continuously collect and process the location in relationship to a personal context of an identified customer. One of the challenges in designing LBS infrastructures is the concurrent design for economic infrastructures and the preservation of privacy of the subjects whose location is tracked. This presentation will explain typical LBS scenarios, the resulting new privacy challenges and user requirements and raises economic questions about privacy-design. The topics will be connected to “mobile identity” to derive what particular identity management issues can be found in LBS.
Information literacy is a mosaic of attitudes, understandings, capabilities and knowledge about which there are three myths. The first myth is that it is about the ability to use ICTs to access a wealth of information. The second is that students entering higher education are information literate because student centred, resource based, and ICT focused learning are now pervasive in secondary education. The third myth is that information literacy development can be addressed by library-centric generic approaches. This paper addresses those myths and emphasises the need for information literacy to be recognised as the critical whole of education and societal issue, fundamental to an information-enabled and better world. In formal education, information literacy can only be developed by infusion into curriculum design, pedagogies, and assessment.
Navigating information, facilitating knowledge: the library, the academy, and student learning
(2004)
Understanding the nature and complementarity of the phenomena of information and knowledge lend not only epistemological clarity to their relationship, but also reaffirms the place of the library in the academic mission of knowledge transfer, acquisition, interpretation, and creation. These in turn reassert the legitimacy of the academic library as necessary participant in the teaching enterprise of colleges and universities. Such legitimacy induces an obligation to teach, and that obligation needs to be explored and implemented with adequate vigor and reach. Librarians and the academy must, however, concede that the scope of the task calls for a solution that goes beyond shared responsibilities. Academic libraries should assume a full teaching function even as they continue their exploration and design of activities and programs aimed at reinforcing information literacy in the various disciplines on campus. All must concede that need for collaboration cannot provide grounds for questioning the desirability of autonomous teaching status for the academic library in information literacy education
