Language universals are statements that are true of all languages, for example: “all languages have stop consonants”. But beneath this simple definition lurks deep ambiguity, and this triggers misunderstanding in both interdisciplinary discourse and within linguistics itself. A core dimension of the ambiguity is captured by the opposition “absolute vs. statistical universal”, although the literature uses these terms in varied ways. Many textbooks draw the boundary between absolute and statistical according to whether a sample of languages contains exceptions to a universal. But the notion of an exception-free sample is not very revealing even if the sample contained all known languages: there is always a chance that an as yet undescribed language, or an unknown language from the past or future, will provide an exception.
Relying on the existing estimates for the production cross sections of mini black holes in models with large extra dimensions, we review strategies for identifying those objects at collider experiments. We further consider a possible stable final state of such black holes and discuss their characteristic signatures. Keywords: Black holes
The taxonomy, diversity, and distribution of the aquatic insect order Trichoptera, caddisflies, are reviewed. The order is among the most important and diverse of all aquatic taxa. Larvae are vital participants in aquatic food webs and their presence and relative abundance are used in the biological assessment and monitoring of water quality. The species described by Linnaeus are listed. The morphology of all life history stages (adults, larvae, and pupae) is diagnosed and major features of the anatomy are illustrated. Major components of life history and biology are summarized. A discussion of phylogenetic studies within the order is presented, including higher classification of the suborders and superfamilies, based on recent literature. Synopses of each of 45 families are presented, including the taxonomic history of the family, a list of all known genera in each family, their general distribution and relative species diversity, and a short overview of family-level biological features. The order contains 600 genera, and approximately 13,000 species.
Lepidoptera phylogeny and systematics : the state of inventorying moth and butterfly diversity
(2007)
The currently recognized robust support for the monophyly of the Lepidoptera (and the superorder Amphiesmenoptera comprising Lepidoptera + Trichoptera) is outlined, and the phylogeny of the principal lineages within the order is reviewed succinctly. The state of the taxonomic inventory of Lepidoptera is discussed separately for ‘micro-moths’, ‘macro-moths’ and butterflies, three assemblages on which work has followed historically somewhat different paths. While currently there are about 160,000 described species of Lepidoptera, the total number of extant species is estimated to be around half a million. On average, just over one thousand new species of Lepidoptera have been described annually in recent years. Allowing for the new synonyms simultaneously established, the net increase in species numbers still exceeds 800/year. Most of the additions are foreseeable in the micro-moth grade, but even for butterflies ca 100 species are added annually. Examples of particularly interesting new high-rank taxa that have been described (or whose significance has become realized) since the middle of the 20th century include the non-glossatan lineages represented by Agathiphaga and Heterobathmia and the heteroneuran families Andesianidae, Palaephatidae, Hedylidae and Micronoctuidae. Some thoughts on how present and future systematic lepidopterology might be prioritised are presented.
Event-by-event multiplicity fluctuations in nucleus-nucleus collisions from low SPS up to RHIC energies have been studied within the HSD transport approach. Fluctuations of baryonic number and electric charge also have been explored for Pb+Pb collisions at SPS energies in comparison to the experimental data from NA49. We find a dominant role of the fluctuations in the nucleon participant number for the final hadron multiplicity fluctuations and a strong influence of the experimental acceptance on the final results.

This study analyzes storyline structure in three Hausa home videos; Mai Kudi (The Rich Man), Sanafahna (with time truth shall dawn) and Albashi (Salary). The study measures storyline structure in these films against a Hollywood film industry model of story writing “the Hero's Journey”. It uses narrative analysis as its analytical tool, and narrative theory as its framework. After analyzing these videos, the study found that the major elements of storyline structure in Vogler's model formed the framework of the storyline structure in Hausa home videos analyzed. However, in spite of the preponderance of these elements within the storyline structure, there are significant variations to Vogler's model. Specifically, Vogler's model has some twelve stages spread on the universal structure of storytelling, i.e. beginning, middle and end. Few of these stages were found to exist in Hausa narrative structure, perhaps due to cultural differences between Western, Indian and Hausa cultures. The study therefore recommends screenwriters and producers to be aware of the existence of standard models of scriptwriting. It also recommends more training for script writers in the Hausa film industry.
Since about the year 2000 a hitherto unidentified species of the genus Leiobunum C. L. Koch, 1839, has rapidly invaded central and western Europe. Records are known from The Netherlands (probably the country of first occurrence in Europe), Germany, Austria and Switzerland. This introduced species, until now, mainly inhabits walls of buildings and rocky environments. Adults characteristically aggregate during daytime into groups of up to 1.000 individuals. The species is described and details on its present distribution, habitat preference, phenology and behaviour are presented.
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.
The work presented in this thesis addresses a key issue of the CBM experiment at FAIR, which aims to study charm production in heavy ion collisions at energies ranging from 10 to 40 AGeV . For the first time in this kinematical range, open charm mesons will be used as a probe of the nuclear fireball. Despite of their short decay length, which is typically in the order of few 100 µm in the laboratory frame, those mesons will be identified by reconstructing their decay vertex.
After he had only tightly lost the election in July 2006, Andrés Manuel López Obrador and his Coalición claimed fraud and asserted that unfair conditions during the campaign had diminished his chances to win the presidency. The paper investigates this latter allegation centering on a perceived campaign of hate, unequal access to campaign resources and malicious treatment by the mass media. It further analyzes the mass media’s performance during the conflictual post electoral period until the final decision of the Federal Electoral Tribunal on September 5th, 2006. While the media’s performance during the campaign tells us about their compliance with fair media coverage mechanisms that have been implemented by electoral reforms in the 1990s, the mass media is uncontained by such measures after the election. Thus, their mode of coverage of the postelectoral conflicts allows us to “test” the mass media’s transformation to a more unbiased, social responsible “fourth estate”. Finally the paper scrutinizes whether the claims of fraud and the protests by the leftist movement resulted in lower levels of institutional trust and democratic support. The analysis of the media performance is based on data provided by the Federal Electoral Institute (IFE). Its Media Monitor encompassed more than 150 TV stations, 240 radio stations and 200 press publications. However, there is no comparable data available for the postelectoral period. Interviews with Mexican media experts, which the author has conducted during the postelectoral period, serve as empirical basis for the second part. Data on the public opinions and attitudes of Mexican citizens are taken from the 2007 Latinobarometro, the 2006 Encuesta Nacional and several polls conducted by Grupo Reforma. The results do not support López Obradors notions. Even though a strong party bias is characteristic of the Mexican media system, all findings hint at a continuity of balanced campaign coverage and fair access to mass media publicity. Coverage during the postelectoral period was more polarized, yet both sides remained at least partially open for oppositional views. The claims of fraud, mass protest mobilization and anti-institutional discourse by Lopez Obrador’s leftist movement seem not to have caused significant loss in institutional trust, support of and satisfaction with democracy, even though these levels remain quite low.
Arabidopsis cell walls contain large amounts of pectins and hemicelluloses, which are predominantly synthesized via the common precursor UDP-glucuronic acid. The major enzyme for the formation of this nucleotide-sugar is UDP-glucose dehydrogenase, catalysing the irreversible oxidation of UDP-glucose into UDP-glucuronic acid. Four functional gene family members and one pseudogene are present in the Arabidopsis genome, and they show distinct tissue-specific expression patterns during plant development. The analyses of reporter gene lines indicate gene expression of UDP-glucose dehydrogenases in growing tissues. The biochemical characterization of the different isoforms shows equal affinities for the cofactor NAD+ (~40 µM) but variable affinities for the substrate UDP-glucose (120–335 µM) and different catalytic constants, suggesting a regulatory role for the different isoforms in carbon partitioning between cell wall formation and sucrose synthesis as the second major UDP-glucose-consuming pathway. UDP-glucose dehydrogenase is feedback inhibited by UDP-xylose. The relatively (compared with a soybean UDP-glucose dehydrogenase) low affinity of the enzymes for the substrate UDP-glucose is paralleled by the weak inhibition of the enzymes by UDP-xylose. The four Arabidopsis UDP-glucose dehydrogenase isoforms oxidize only UDP-glucose as a substrate. Nucleotide-sugars, which are converted by similar enzymes in bacteria, are not accepted as substrates for the Arabidopsis enzymes.
Another accruing and evolving collection holding published university documents (documents made publicly available) and non-official institutional records, plus 'grey literature' and ephemera relating to UB and its forerunner institutions. It includes documents harvested from UB Website. This is an artificially created collection. Some of these records may also exist in the homogenous institutional archive collections and in the BDSC.
Iterative arrays (IAs) are a, parallel computational model with a sequential processing of the input. They are one-dimensional arrays of interacting identical deterministic finite automata. In this note, realtime-lAs with sublinear space bounds are used to accept formal languages. The existence of a proper hierarchy of space complexity classes between logarithmic anel linear space bounds is proved. Furthermore, an optimal spacc lower bound for non-regular language recognition is shown. Key words: Iterative arrays, cellular automata, space bounded computations, decidability questions, formal languages, theory of computation
Applying an investment perspective to higher education, the paper presents detailed empirical evidence on the rate of return to higher education and its determinants. Employing a sample of 17,180 higher education graduates derived from the German Labor Force Survey 2004, we show considerable variation in the rates of return to higher education across the different subjects, with some subjects on average not representing attractive private investments from an economic point of view. We find that the decision what to study is worth several hundred thousand Euros. Applying regression analysis, we find gender- and degree-specific return advantages only in certain subjects. Comparing the return of an investment in higher education and the production cost of higher education, we show that more expensive subjects (apart from Medicine) yield a lower return. When considering the cost of study, the overall order of attractiveness of the different forms of education remains stable, but the investment in further subjects is no longer clearly attractive.

Does BPO pay off at the firm-level? Although there are several studies which analyze the potential benefits of BPO, there is a virtual absence of research papers on BPO outcomes. Based on an analysis of 137 Business process outsourcing (BPO) ventures at 254 German banks in a period between 1994 and 2005, we found that the outsourcer's financial performance in terms of profitability and cost efficiency was increased significantly compared to industry peers without BPO. The increase stems not from workforce reductions but rather from increased employee productivity. Further, we show how BPO governance ensures BPO success: individually negotiated outsourcing contracts help to improve cost efficiency and profitability measures. Relational governance based on trust has only positive effects on profitability.

Humans possess a number concept that differs from its predecessors in animal cognition in two crucial respects: (1) it is based on a numerical sequence whose elements are not confined to quantitative contexts, but can indicate cardinal/quantitative as well as ordinal and even nominal properties of empirical objects (e.g. ‘five buses’: cardinal; ‘the fifth bus’: ordinal; ‘the #5 bus’: nominal), and (2) it can involve recursion and, via recursion, discrete infinity. In contrast to that, the predecessors of numerical cognition that we find in animals and human infants rely on finite and iconic representations that are limited to cardinality and do not support a unified concept of number. In this paper, I argue that the way such a unified number concept could evolve in humans is via verbal sequences that are employed as numerical tools, that is, sequences of words whose elements are associated with empirical objects in number assignments. In particular, I show that a certain kind of number words, namely the counting sequences of natural languages, can be characterised as a central instance of verbal numerical tools. I describe a possible scenario for the emergence of such verbal numerical tools in human history that starts from iconic roots and that suggests that in a process of co-evolution, the gradual emergence of counting sequences and the development of an increasingly comprehensive number concept supported each other. On this account, it is language that opened the way for numerical cognition, suggesting that it is no accident that the same species that possesses the language faculty as a unique trait, should also be the one that developed a systematic concept of number.
Attraction and commercial success of web sites depend heavily on the additional values visitors may find. Here, individual, automatically obtained and maintained user profiles are the key for user satisfaction. This contribution shows for the example of a cooking information site how user profiles might be obtained using category information provided by cooking recipes. It is shown that metrical distance functions and standard clustering procedures lead to erroneous results. Instead, we propose a new mutual information based clustering approach and outline its implications for the example of user profiling.
