Abstract
Purpose
The extension of the vacuum-assisted multipoint moulding (VAMM) technology to a broader field of geometries makes it necessary to extend it with attachments to the enhanced vacuum-assisted multipoint moulding with additive attachments (EMMA) technology. Therefore, it is necessary to build additive manufactured attachments on a curved silicone surface by fused filament fabrication (FFF). The main challenge of FFF on a silicone-made build plate is the adhesion of the part on the build plate. Hence, the purpose of this paper is to find suitable and reliably manufacturable material and adhesion promoter combinations for the use of the FFF on silicone build plates.
Design/methodology/approach
The combinations of seven different filaments and four adhesion promoters were investigated with an experimental study. Therefore, four different specimen geometries were built with the different combinations and tested in a tensile test, and some of the specimens were analysed with a confocal laser scanning microscope (CLSM).
Findings
This study proves that the FFF on unheated silicone building plates is possible for several material combinations. As a filament material, polylactide can reliably be manufactured with all of the investigated adhesion promoters on the silicone build plate. Thereby, the highest adhesion strengths were achieved with an adhesive foil as an adhesion promoter, whereas the glue stick is the most appropriate solution. The investigations with the CLSM showed that there are large differences in the manifestation of the first layer depending on the adhesion promoter used.
Originality/value
To the best of the authors’ knowledge, this study is the first to demonstrate the manufacturing of FFF-made attachments on silicone build plates for the EMMA process. This paper provides measurement data on the build plate adhesion of the attachments on silicone-made build plates.

Abstract
Purpose: Mentioning a criminal’s country of origin in crime news is a divisive and much-discussed issue among both journalists and members of society. Scholars assume that mentioning a criminal’s foreign origin could develop and maintain prejudices against individuals with a migrant background among news recipients. However, until now, no attention has been paid to what increases the likelihood that a journalist does or does not mention a criminal’s country of origin when reporting on crimes. Methodology/approach: One possible explanation is that the frequency and intensity of specific news factors could lead to mentioning a criminal’s origin, since increased importance of a news story is usually assigned when many high-intensity news factors occur. Even though numerous studies have determined the frequency of specific news factors in (crime) news, the explanation hypothesized in this chapter has not yet been examined. To investigate this supposition empirically, a quantitative content analysis of four German prime newscasts (n = 290), including public and private broadcasts, was conducted in the current study. Findings: The findings indicate that mentioning criminals’ origins is still common practice in journalism; furthermore, criminals with foreign origins are explicitly represented as foreign almost ten times more often than German-origin criminals are explicitly mentioned as German. News factors such as personalization, location, and influence show some effects of positively predicting journalistic mentioning of a criminal’s country of origin.

Abstract
In der neueren Fachliteratur findet die Frage nach der konjunkturellen Abhängigkeit des Fremdenverkehrs wenig Beachtung. Diese Tatsache drfte wohl auf die weitverbreitete Ansicht zurckzufhren sein, der moderne Tourismus sei nicht konjunkturabhängig oder nicht mehr so sehr konjunk‐turempfindlich wie in frheren Zeiten. Diese abgeschwächte Formulierung der vorherrschenden Ansicht beruht möglicherweise auf einem Trugschluss. In der Nachkriegszeit verliefen die Konjunkturschwankungen dank effizienter Methoden der «Globalsteuerung» der Wirtschaft relativ mild mit dem Ergebnis, dass in Abschwungs‐ und Rezessionsjahren bisher immer nur vergleichsweise ein geringer Teil der Arbeitnehmer direkt betroffen worden ist. Wenn aber das konjunkturelle Auf und Ab weniger heftig als in der Vorkriegszeit ausfällt und deshalb die Arbeitslosigkeit sich in relativ engen Grenzen hält, dann ist die Vermutung begründet, dass auch die Auswirkungen auf den Tourismus entsprechend gering sind.

Abstract
Die Empfehlung an die Verantwortlichen in Fremdenverkehrsorten und ‐regionen, zur Abwendung weiterer Marktanteilsverluste ein innovatives Marketing zu betreiben, stösst häufig auf Ablehnung oder Resignation bei den Betroffenen. Es wird eingewendet, die von der Betriebswirtschaftslehre für Konsumgüterproduzenten entwickelten Marketinginstrumente könnten nicht einfach auf den Fremdenverkehr übertragen werden. Die Fremdenver‐kehrsstellen (Verkehrsämter, Kurverwaltungen, regionale Fremdenverkehrsverbände) hätten z.B. keinen Einfluss auf die Produktgestaltung der örtlichen Leistungsträger, sie würden nur eine koordinierende Funktion ausüben und allenfalls Werbung für den Fremdenverkehrsort oder die ‐region betreiben. Tatsächlich ist der Bereich des Binnen‐marketings (auch intramulares Marketing oder Innenmarketing genannt) im Fremdenverkehr durch besondere Schwierigkeiten gekennzeichnet. Das “Produkt” Fremdenverkehrsort oder Kurort umfasst stets ein ganzes Leistungsbündel, für dessen Herstellung viele “Produzenten” verantwortlich sind. Die Besonderheiten des Marketings im Fremdenverkehr ergeben sich deshalb vor allem aus der Tatsache, dass Marketing in Erholungsorten, Kurorten, Heilbädern und Städten sowie in Fremdenverkehrsregionen in der Praxis stets Gerne in schaftsmarketing ist. Um erfolgreiches Marketing nach aussen betreiben zu können, er‐weist es sich im Fremdenverkehr als notwendig, zuerst eine Konzeption für das Marketing nach innen (Binnenmarketing) zu erarbeiten. Für jeden Fremdenverkehrsort gilt: “Marketing begins at home”.

Abstract
The significance of literature in nation-building in two “second generation” nations, Germany and Norway, is discussed. In both countries a specific national literature was constituted parallel to the political institutions during the latter half of the 19th century. Yet there are clear differences in political effects in the two cases. In Norway, the struggle for national independence up to 1905 entailed a significant democratization of society. Germany, in the wake of the revolution of 1848, developed into a politically authoritarian regime, fully established under Prussian leadership in 1871.
These processes are mirrored in the position of literature. In Norway, where artistic traditions were absent, the national literature was a product of the 19th century, and emerged in close connection to ongoing political debates. In Germany, the Weimar heritage had gained classical status during the 1850s. Thus, the problem was foremost that of redefining the spiritual heritage to fit the history of the German Reich.
A related difference is found in the diffusion of literature through its most important channel – the school system. Norway developed a modern, uniform school, where the nation’s new literature was accorded a central place. In Germany, a more class-based school system was cemented, and the idea of diffusing the cultural heritage to the population at large held a weak position.
Along with these institutional factors, the development of national literatures in the two countries is seen in the light of regional specificities, constellations of literary genres with high and low prestige, and the social and political position of writers.

Abstract
Purpose
The objectives of the study, which focuses on reproductive health care services, are to identify factors that impede adequate access to care for migrant women and to identify possible solutions.
Design/methodology/approach
In this case study, problem‐based, semi‐structured individual interviews were conducted with 12 migrant women, eight staff members of non‐governmental organizations (NGOs), and eight staff members of a public hospital (physicians, nurses). The transcripts were analyzed using a grounded thematic approach.
Findings
Problems in access to services were identified in four areas: accessibility/information; institutional infrastructure; language barriers; and cultural competences.
Social implications
There is a need to develop culture‐specific understanding of health amongst service providers working in public hospitals. It is also necessary to raise awareness of traditional beliefs and behavior of migrant women to maximize good quality care. A closer collaboration of hospitals and NGOs is recommended, not least in order to ensure the demand‐ and needs‐orientation, appropriateness, effectiveness, and efficiency of health care for migrant women. Migrant women mentioned different approaches to delivering care – these solutions should, where possible, be applied in practice.
Originality/value
The study correlates and supports knowledge from existing literature regarding possible barriers to the use of health care services by women with migrant backgrounds. Recommendations for overcoming existing barriers are also identified by research participants.

Abstract
What are the consequences of urban life in an ethno-nationally contested city? How do everyday practices confront municipal strategies that attempt to control such urban situations? Focusing on urban life in which daily negotiation of ethno-national differences occurs, this chapter considers the nuances of urban politics and the use and meaning of the urban space, i.e., the micro-politics and the social dynamic of place-making, and their role in the struggle for urban citizenship in an ethno-nationally mixed city. Discourse analysis and ethnographic encounters define the annual Holiday of Holidays festival in the Israeli–Palestinian neighborhood of Wadi Nisnas as integral to Haifa's strategy for promoting itself as a site of coexistence. The neighborhood serves the entire city in that its “Arab” urban space has become the emblem of that coexistence. This manipulation by the municipality is, however, not reinforced by urban regeneration and heritage management of the local Palestinian community. Nonetheless coexistence discourse is also employed by the residents themselves, suggesting a more nuanced understanding of the role of urban space in promoting the city, as well as of concepts of local identity and citizenship.

Abstract
Purpose
This study aims to offer an original criterion of assessment for examiners of practice-based doctorates in contemporary arts practices, based upon the degree of intrigue, perceptual and conceptual, afforded by the research outputs. It is argued that intrigue is the necessary stimulus for the states of attention required for the recognition of fresh understanding and the acquisition of new knowledge from such outputs. The paper is intended to support doctoral students structuring theses for such research, those responsible for assessing proposals in university cross-disciplinary research committees with limited experience of practice-based research and the examiners of such research.
Design/methodology/approach
Acknowledging the several decades of work already published on practice-based research, this study adopts an aesthetic cognitivist position from which the visual arts are construed as powerful means of deepening our understanding, a source of non-propositional knowledge on a par with, although qualitatively different from, the way that the sciences are accepted as the means to propositional knowledge.
Findings
A case study demonstrates the efficacy of applying the proposed criterion in the assessment of practice-based doctoral research.
Social implications
Within the social context of academic research, the article strengthens the validation of practice-based research.
Originality/value
The terms perceptual intrigue and conceptual intrigue are coined as values implicit in aesthetic cognitivism; they are construed as the initial stimuli for the state of attentiveness required for fresh understanding, and the degree of balance between them is proposed as an original criterion for the assessment of practice-based research.
