Unique column combinations of a relational database table are sets of columns that contain only unique values. Discovering such combinations is a fundamental research problem and has many different data management and knowledge discovery applications. Existing discovery algorithms are either brute force or have a high memory load and can thus be applied only to small datasets or samples. In this paper, the wellknown GORDIAN algorithm and "Apriori-based" algorithms are compared and analyzed for further optimization. We greatly improve the Apriori algorithms through efficient candidate generation and statistics-based pruning methods. A hybrid solution HCAGORDIAN combines the advantages of GORDIAN and our new algorithm HCA, and it significantly outperforms all previous work in many situations.
Adverbs and Adjunction
(2000)
The papers collected in this volume were all presented at the workshop on Adverbs and Adjunction, held at the University of Tromsoe, in April 17-18, 1999. The presentations by Kristin M. Eide &Inghild Flaate, Henriette de Swart, Artemis Alexiadou and Adam Wyner could not be included here.
The articles deal with the syntax, semantics and morpbology of adverbs and their interaction with other syntactic phenomena. A number of tbe contributions is concerned with an evaluation of the hypothesis that adverbs are specifiers of functional heads, which are universally ordered. Specifically, Adger &Tsoulas argue that locative adverbials are licensed by an aspectual head that encodes telicity, while manner adverbials are licensed by a light verb that encodes agentivity, both being situated low in the VP structure. According to the authors, the prime function of these heads is to license aspects of the featural composition of the object, and the licensing of these low adverbials is a by-product of the way that the EPP features of these heads functions. Costa presents data from European Portuguese in support of the traditional analysis of adverbs as adjuncts. Ernst shows that manner, measure, and domain adverbs, and more generally, adverbs and other adjuncts such as participant PPs and adjunct secondary predicates (depictives), are not rigidly ordered. Hence the paper supports theories where linear order is largely a function of the interaction of compositional rules for the various adjuncts, plus their lexico-semantic requirements.
For Haider, adverbials are adjoined or embedded, depending on the relation to the head of the containing phrase: they are adjoined if they precede the head of the containing phrase. They are embedded if they follow the head of tbe containing phrase. But the relative order of adverbials is a reflex of an interface condition. Moreover, the order pattern of adverbials in the extraposition domain is a function of linear incrementality in a non-compositional subdomain. Laenzlinger, on the other hand, claims that adverbs occupy the A'-specifier of their semantically related functional projection. They are formally licensed via the mechanism of feature checking, which links their distribution to their interpretation. He also considers adverb placement and its interaction with Verb/Argument Movement, fronting and extraposition. The interaction between A-scrambling and adverb placement crosslinguistically is also investigated by Hoffman in a minimalist framework. He claims that adverbs can be pronounced in any set of syntactic positions, but the choice among the various positions is made on non syntactic grounds.
Two papers are concerned with adverbial case. Pereltsvaig examines nominal adverbials marked with Accusative Case, with particular focus on Russian and Finnish. She shows that Accusative adverbials exhibit object-like behavior. She argues that Accusative Case is related to aspectual properties of the VP, and it is thus argued that Structural Accusative Case is checked in [Spec, AspP]. But not all occurrences of morphological accusative case derive from Structural Accusative Case. Thus, the contrasts between Russian and Finnish are explained by the claim that Russian uses accusative case marking for NPs in default objective Case position, whereas Finnish uses partitive in the same position. Manninen shows that in Finnish- adverbs can be analyzed as a sub-category of adjectives and nouns, as they are really case-inflected adjectives and nouns. Manninen proposes that these bear lexical 'adverb' case, i. e. that is they have the form of K(asus;Kase)Ps.
Finally, Vegnaduzzo investigates the polysemy of the ltalian adverb ancora showing that this is only apperent. She argues that all the different readings depend upon the context where it is inserted: each reading is derived by compositionality of ancora basic meaning and the semantic properties of the argument structure of the verb.

As Albania is accelerating its preparations towards the European Union candidate status, numerous areas of public policy and practices undergo intensive development processes. Regional development policy is a very new area of public policy in Albania, and needs research and development. This study focuses on the process of sustainable development in Albania, by analyzing and comparing the regional development of regions of Tirana, Shkodra and Kukes. The methodology used consists of a literature/desk review; analytical and comparative approach; qualitative interviews; quantitative data collection; analysis. The research is organized in five chapters. First chapter provides an overview of the study framework. The second outlines the theory and scientific framework for sustainable and regional development in relation with geography. The third chapter presents the picture of the regional development in Albania, analyzing the disparities and regional development in the light of EU requirements and NUTS division. Chapter 4 continues by analyzing and comparing the regional development of the regions: Tirana – driver for change, Shkodra – the North in Development and Kukes – the “shrinking” region. Chapter 5 presents the conclusions and recommendations. This research comes to the conclusions that if growth in Albania is to be increased and sustained, a regional development policy needs to be established.
Alexander von Humboldt
(2022)
This book aims to view and to understand Alexander von Humboldt from different perspectives and in varying disciplinary contexts. His contributions addressed numerous topics in the earth but also life sciences—spanning from geo-botany, climatology, paleontology, oceanography, mineralogy, resources, and hydrogeology to links between the environmental impact of humans, erosion, and climate change. From the very beginning, he paved the way for a modern, integrated earth system science approach to decipher, characterize, and model the different forcing factors and their feedback mechanisms. It becomes obvious that Humboldt’s holistic approach is far beyond simple description and empiric data collection. As documented and analyzed in the different texts of this volume, he combines observation and analysis with emotions and subjective perceptions in a very affectionate way. However, this publication does not intend to add another encyclopedic text compilation but to observe and critically analyze this unique personality´s relevance in a modern context, particularly in discussing environmental and social key issues in the twenty-first century.

Version Control Systems (VCS) allow developers to manage changes to software artifacts. Developers interact with VCSs through a variety of client programs, such as graphical front-ends or command line tools. It is desirable to use the same version control client program against different VCSs. Unfortunately, no established abstraction over VCS concepts exists. Instead, VCS client programs implement ad-hoc solutions to support interaction with multiple VCSs. This thesis presents Pur, an abstraction over version control concepts that allows building rich client programs that can interact with multiple VCSs. We provide an implementation of this abstraction and validate it by implementing a client application.
As a non-contact process laser beam melt ablation offers several advantages compared to conventional processing mechanisms. During ablation the surface of the workpiece is molten by the energy of a CO2-laser beam, this melt is then driven out by the impulse of an additional process gas. Although the idea behind laser beam melt ablation is rather simple, the process itself has a major limitation in practical applications: with increasing ablation rate surface quality of the workpiece processed declines rapidly. With different ablation rates different surface structures can be distinguished, which can be characterised by suitable surface parameters. The corresponding regimes of pattern formation are found in linear and non-linear statistical properties of the recorded process emissions as well. While the ablation rate can be represented in terms of the line-energy, this parameter does not provide sufficient information about the full behaviour of the system. The dynamics of the system is dominated by oscillations due to the laser cycle but includes some periodically driven non-linear processes as well. Upon the basis of the measured time series, a corresponding model is developed. The deeper understanding of the process can be used to develop strategies for a process control.

The noble way to substantiate decisions that affect many people is to ask these people for their opinions. For governments that run whole countries, this means asking all citizens for their views to consider their situations and needs.
Organizations such as Africa's Voices Foundation, who want to facilitate communication between decision-makers and citizens of a country, have difficulty mediating between these groups. To enable understanding, statements need to be summarized and visualized. Accomplishing these goals in a way that does justice to the citizens' voices and situations proves challenging. Standard charts do not help this cause as they fail to create empathy for the people behind their graphical abstractions. Furthermore, these charts do not create trust in the data they are representing as there is no way to see or navigate back to the underlying code and the original data. To fulfill these functions, visualizations would highly benefit from interactions to explore the displayed data, which standard charts often only limitedly provide.
To help improve the understanding of people's voices, we developed and categorized 80 ideas for new visualizations, new interactions, and better connections between different charts, which we present in this report. From those ideas, we implemented 10 prototypes and two systems that integrate different visualizations. We show that this integration allows consistent appearance and behavior of visualizations. The visualizations all share the same main concept: representing each individual with a single dot. To realize this idea, we discuss technologies that efficiently allow the rendering of a large number of these dots. With these visualizations, direct interactions with representations of individuals are achievable by clicking on them or by dragging a selection around them. This direct interaction is only possible with a bidirectional connection from the visualization to the data it displays. We discuss different strategies for bidirectional mappings and the trade-offs involved. Having unified behavior across visualizations enhances exploration. For our prototypes, that includes grouping, filtering, highlighting, and coloring of dots. Our prototyping work was enabled by the development environment Lively4. We explain which parts of Lively4 facilitated our prototyping process. Finally, we evaluate our approach to domain problems and our developed visualization concepts.
Our work provides inspiration and a starting point for visualization development in this domain. Our visualizations can improve communication between citizens and their government and motivate empathetic decisions. Our approach, combining low-level entities to create visualizations, provides value to an explorative and empathetic workflow. We show that the design space for visualizing this kind of data has a lot of potential and that it is possible to combine qualitative and quantitative approaches to data analysis.

This book serves as a gateway to the Elementa grammaticae Huronicae, an eighteenth-century grammar of the Wendat (‘Huron’) language by Jesuit Pierre-Philippe Potier (1708–1781). The volume falls into three main parts. The first part introduces the grammar and some of its contexts, offering information about the Huron-Wendat and Wyandot, the early modern Jesuit mission in New France and the Jesuits’ linguistic output. The heart of the volume is made up by its second part, a text edition of the Elementa. The third part presents some avenues of research by way of specific case studies.

Anisotropic edge problems
(2002)
Persistence of stock returns is an extensively studied and discussed theme in the analysis of financial markets. Antipersistence is usually attributed to volatilities. However, not only volatilities but also stock returns can exhibit antipersistence. Antipersistent noise has a somewhat rougher appearance than Gaussian noise. Heuristically spoken, price movements are more likely followed by movements in the opposite direction than in the same direction. The pertaining integrated process exhibits a smaller range – prices seem to stay in the vicinity of the initial value. We apply a widely used test based upon the modified R/S-Method by Lo [1991] to daily returns of 21 German stocks from 1960 to 2008. Combining this test with the concept of moving windows by Carbone et al. [2004], we are able to determine periods of antipersistence for some of the series under examination. Our results suggest that antipersistence can be found for stocks and periods where extraordinary corporate actions such as mergers & acquisitions or financial distress are present. These effects should be properly accounted for when choosing and designing models for inference.

Der vorliegende dritte Band der Serie "Interdisciplinary Studies on Information Structure" enthält sieben Beiträge aus verschiedenen Projekten des Sonderforschungsbereiches "Informationsstruktur: Die sprachlichen Mittel der Gliederung von Äußerung, Satz und Text" (SFB 632). Der Titel "Approaches and Findings in Oral, Written and Gestural Language" reflektiert die Bandbreite der Untersuchungen zum Thema Informationsstruktur. In ihrem Artikel hinterfragt Elke Kasimir die Zuverlässigkeit des sog. Frage-Antwort-Tests zur Bestimmung des fokussierten Elementes in Sätzen. Ihr alternativer Lösungsvorschlag wird in dem Kommentar von Thomas Weskott kritisch diskutiert. Der Artikel von Paul Elbourne befasst sich mit Phänomenen der Ellipse und bietet eine neue semantische Analyse an. Spezielle morphologisch stark markierte Fokuskonstruktionen aus fünf verschiedenen afrikanischen Sprachen der Gur- und Kwa-Sprachgruppe werden von Ines Fiedler und Anne Schwarz analysiert und diachronisch interpretiert. Ebenfalls sprachhistorisch ausgerichtet ist der Artikel von Roland Hinterhölzl, Svetlana Petrova und Michael Solf, die Belege für die Interaktion von Wortstellung und Informationsstruktur bereits in der althochdeutschen Tatian-Übersetzung fanden. Anke Sennema, Ruben van de Vijver, Susanne E. Carroll und Anne Zimmer-Stahl diskutieren anhand einer Serie von Experimenten die Nutzung von Prosodie, Wortlänge und –Stellung für die semantischen Interpretation in der Erst- und Zweitsprache. Die besondere Rolle von Gestik in Verbindung mit Intonation für die Strukturierung des sprachlichen Diskurses wird von Stefanie Jannedy und Norma Mendoza-Denton hervorgehoben.
This volume provides an overview of current research priorities in the analysis of face-to-face-interaction in Slavic speaking language communities. The core of this volume ranges from discourse analysis in the tradition of interactional linguistics and conversation analysis to newer methods of politeness research. A further field includes empirical and interpretive methods of modern sociolinguistics and statistical analysis of spoken language in casual and institutional talks. Several papers focus on a semantic or syntactic analysis of talk-in-interaction by trying to show how interlocutors use certain lexical, grammatical, syntactic and multimodal or prosodic means for the management of interaction in performing specific actions, genres and displaying negotiations of epistemic, evidential or evaluative stances. The volume is rounded out by contributions to the theory of politeness where strategies of face-work in casual as well as institutional discourse are analyzed, or in which social tasks entertained by code-switching and language alternation within the interaction of bilinguals are discussed.
