The role of market oriented tourist policies in the planned economies of socialist Eastern Europe has been long overlooked. This article examines how the socialist regime in Romania moved from sheer ideological rhetoric to commercialism and market-driven strategies when promoting Romania as a tourist destination in the ‘West’ between the 1960s and the 1980s. It argues that there was a continual shifting between using tourism as an ideological tool and a certain pragmatism that was needed to turn Romania into a desirable tourist destination. [less ▲]

Log message template identification aims to convert raw logs containing free-formed log messages into structured logs to be processed by automated log-based analysis, such as anomaly detection and model inference. While many techniques have been proposed in the literature, only two recent studies provide a comprehensive evaluation and comparison of the techniques using an established benchmark composed of real-world logs. Nevertheless, we argue that both studies have the following issues: (1) they used different accuracy metrics without comparison between them, (2) some ground-truth (oracle) templates are incorrect, and (3) the accuracy evaluation results do not provide any information regarding incorrectly identified templates. In this paper, we address the above issues by providing three guidelines for assessing the accuracy of log template identification techniques: (1) use appropriate accuracy metrics, (2) perform oracle template correction, and (3) perform analysis of incorrect templates. We then assess the application of such guidelines through a comprehensive evaluation of 14 existing template identification techniques on the established benchmark logs. Results show very different insights than existing studies and in particular a much less optimistic outlook on existing techniques. [less ▲]

We study the case of Vietnam to assess the long-lasting role of institutional and historical legacy on entrepreneurial outcomes. In particular, we investigate the detrimental effect of socialist institutions on entrepreneurship. Vietnam offers a unique quasi-experimental setting because the country was divided into the socialist North and the nonsocialist South for a relatively short period of two decades. After reunification, the South adopted the institutional framework conditions of the North. To assess the relationship between socialist history and entrepreneurship in this unique setting, we survey more than 3,000 North and South Vietnamese individuals more than four decades after the reunification of the country. We find that North Vietnamese respondents have lower entrepreneurship intentions, are less likely to select into entrepreneurship education programs, and are less willing to engage in a business takeover. These patterns indicate the persistence of historical differences in institutional framework conditions on entrepreneurship. We conclude by outlining the implications of a socialist legacy for entrepreneurship theory and policymakers. [less ▲]

Ambiguity is a pervasive issue in natural-language requirements. A common source of ambiguity in requirements is when a pronoun is anaphoric. In requirements engineering, anaphoric ambiguity occurs when a pronoun can plausibly refer to different entities and thus be interpreted differently by different readers. In this paper, we develop an accurate and practical automated approach for handling anaphoric ambiguity in requirements, addressing both ambiguity detection and anaphora interpretation. In view of the multiple competing natural language processing (NLP) and machine learning (ML) technologies that one can utilize, we simultaneously pursue six alternative solutions, empirically assessing each using a collection of ~1,350 industrial requirements. The alternative solution strategies that we consider are natural choices induced by the existing technologies; these choices frequently arise in other automation tasks involving natural-language requirements. A side-by-side empirical examination of these choices helps develop insights about the usefulness of different state-of-the-art NLP and ML technologies for addressing requirements engineering problems. For the ambiguity detection task, we observe that supervised ML outperforms both a large-scale language model, SpanBERT (a variant of BERT), as well as a solution assembled from off-the-shelf NLP coreference resolvers. In contrast, for anaphora interpretation, SpanBERT yields the most accurate solution. In our evaluation, (1) the best solution for anaphoric ambiguity detection has an average precision of ~60% and a recall of 100%, and (2) the best solution for anaphora interpretation (resolution) has an average success rate of ~98%.

Spätestens seit der Covid-19-Pandemie ist die Rolle von Grenzen, die in den letzten Jahrzehnten an Bedeutung gewonnen haben, nicht mehr zu übersehen. Diese Entwicklung, die sich mühelos auf der globalen Ebene rekonstruieren lässt, ist mit dem Virus auch in die europäischen Grenzregionen vorgedrungen. Dort ist die europäische Grenzraumforschung nun mit Phänomenen konfrontiert, mit denen sie sich bisher kaum auseinandergesetzt hat. Der Beitrag wendet sich solchen Phänomenen zu und arbeitet exemplarisch das Zusammenspiel von Ver- und Entgrenzungsprozessen im Kontext des Covidfencing heraus. Dafür werden soziale Aushandlungsprozesse der Grenzschließungen in der Großregion SaarLorLux und im deutsch-polnischen Grenzgebiet als „people’s resilience“ thematisiert. Darauf aufbauend werden Überlegungen vorgestellt, wie sich die europäische Grenzraumforschung für Phänomene und Fragestellungen in Zeiten der Vergrenzungen aufstellen kann. Der internationalen Grenzforschung folgend wird eine Erweiterung der Forschungsagenda um alltagskulturelle Fragen vorgeschlagen, die einen Erkenntnisgewinn versprechen. Außerdem wird eine Justierung des verbreiteten Grenzbegriffs vorgeschlagen, um die Grenze als Gegenstand alltagskultureller Aushandlungen erschließbar zu machen. [less ▲]

In diesem Beitrag wird der Umgang mit wissenschaftssprachlichen Wortverbindungen in den beiden Textmustern Paraphrase und Argumentation von Texten luxemburgischer Studienanfänger der Germanistik mit L2 Deutsch genau unter die Lupe genommen. Dafür wird ein Korpus von 37 Lernendentexten nach korpuslinguistischen Kriterien aufbereitet und qualitativ analysiert. Es wird untersucht, welche Wortverbindungen für die beiden Textmuster typisch sind, welche Wortverbindungen bereits beherrscht werden und wo Schwierigkeiten auftreten. Die Untersuchung ergibt, dass die Verwendung von Wortverbindungen textmusterspezifisch ist. Die Fehleranalyse zeigt außerdem, dass von 195 verwendeten Wortverbindungen fast ein Drittel fehlerhaft sind. Dabei treten die größten Schwierigkeiten bei der Trennung zwischen Alltagssprache/Umgangssprache und Wissenschaftssprache auf. Als Maßnahmen für den Unterricht wird das Arbeiten mit Wortverbindungslisten, das selbstständige Ergänzen solcher Listen durch Analysen wissenschaftlicher Mustertexte, die Selbstkontrolle am Eigentext und das Arbeiten mit Korpora empfohlen.

Customer Journey Mapping is a widespread service design tool that synthesizes and communicates user research insights to stakeholders. In its common form, a journey map is a synthetic (typically non-interactive) visualization of the key steps of the users’ experience with a service or product. By decomposing the elements of a journey map and staging them under the form of a physical and interactive installation, we intend to leverage the power of journey mapping to break silos and prompt employees within an organization to discover end-users journeys in a compelling and empathic way. This aims to support the user-centered maturity of the organization by developing employees’ curiosity and empathy towards users. We illustrate this approach through a case study on railway passengers’ experiences. We explore the value of richer transfers of user research insights through physical journey maps and discuss design processes and mediums enabling journey maps to come to life. [less ▲]

Empathy towards users is crucial to the design of user-centered technologies and services. Previous research focused on defining empathy and its role in the design process for triggering empathy for end-users. However, there is a lack of empathy measurement instruments in design. Most previous work focused on designers, overlooking the need for other stakeholders to develop empathy towards the users to break organizational silos and deliver high-quality user-centered services and products. In this contribution, we share the preliminary stages of the development of an empathy scale for service design. We build on empathy literature from psychology and design to define 18 items representing four empathy dimensions. We report on the definition of these dimensions and their underlying items, and present preliminary studies in which we reviewed the first version of the scale with experts and stakeholders.
