Since light pollution is rarely integrated into conservation approaches, effective mitigation strategies towards environmentally friendly lighting that drastically reduce insect attraction are urgently needed. Here, we tested novel luminaires in two experiments (i) at a controlled experimental field site and (ii) on streets within three municipalities. The luminaires are individually tailored to only emit light onto the target area and to reduce spill light. In addition, a customized shielding renders the light source nearly invisible beyond the lit area. We show that these novel luminaires significantly reduce the attraction effect on flying insects compared to different conventional luminaires with the same illuminance on the ground. This underlines the huge potential of spatially optimized lighting to help to bend the curve of global insect decline without compromising human safety aspects. A customized light distribution should therefore be part of sustainable future lighting concepts, most relevant in the vicinity of protected areas.

ALAN attracts nocturnal insects from their native ecosystems and disturbs their functions in the food web. Road lights in this context are ubiquitous and relevant ALAN sources that are often not considered in conservation approaches. In a previous study we showed that shielded LED road lights are suited to be part of conservation measures by effectively reducing the attraction of nocturnal insects. Here we show that this positive effect holds true for parasitoid wasps in an experimental BACI design (Before-After-Control-Impact). Combining morphological with molecular and phylogenetic analyses, we identified 106 individuals (62 morphotypes) of a minimum of 45 genera out of 13 Hymenoptera families. We were able to identify 21 species, 11 of which are newly reported in Southern Germany (Baden-Württemberg). Further combining knowledge on life history and host appearance from our data and the literature, we discuss potential impacts of ALAN ranging from an influence on nocturnal pollination via parasitoid pressure on moth species and biological control of invasive pest species to tritrophic interactions between primary and secondary parasitoids. We conclusively think that shielded LED road lights will reduce the ecological impact of ALAN on parasitoid wasps in a large and undescribed number of taxa with different host associations, likely affecting associated ecosystem functions such as biological control.

Wegen des fehlenden Rechtscharakters der Deklaration gibt es keine rechtliche Verpflichtung, die vereinbarten Ziele umzusetzen, keine Rechtsansprüche oder Verpflichtungen zwischen den Teilnehmerländern untereinander, insbesondere auch keinen Anspruch auf Anerkennung der Studien und Abschlüsse im Ausland. Die platte Übernahme der US-amerikanischen Abschlußbezeichnungen des gestuften Studiums stellt einen Bruch mit den Traditionen der deutschen Hochschulen dar und steht im offenen Widerspruch zu der im Bologna-Abkommen feierlich unterzeichneten Achtung vor der eigenen Kultur, Sprache und Tradition. Während die durch das gestufte Studiensystem charakterisierten angelsächsischen Länder von ihrem traditionellen System Abschied nehmen und – teilweise expressis verbis – auf das einhundertjährige bewährte deutsche Diplomstudium zugehen, verordnen Politiker unseren Hochschulen eine Roßkur mit höchst fatalen Folgen für die Zukunft. Diesen Bestrebungen sollte Einhalt geboten werden, damit in Ruhe und mit Überlegung eine inhaltliche Reform begonnen werden kann, die die Stärken unseres Bildungssystems wieder innerhalb Deutschlands und weltweit zur Geltung bringt, anstatt es auf das niedrigste bekannte Niveau des Bachelors zu reduzieren.

A1 - Scheeg, Jochen T1 - Alternative digital platforms: comparative analysis through the lens of Corporate Aikido JF - Information Systems and e-Business Management N2 - Competing with dominant players in the digital platform (DP) economy is an increasingly complex and expensive endeavor for alternative digital platform (ADP) providers trying to disrupt established platform ecosystems. Nevertheless, ADPs position themselves deliberately in the competitive space of large competitors, targeting customer groups whose values and mindsets differ from mainstream DPs. Although there are many examples to find in practice, the variety of ADPs across different DP ecosystems and industries, especially in regards of strategic objectives, directions and characteristics, has not been researched in-depth yet. Based on a systematic, practice-based artifact review, this paper analyses and compares 105 ADPs in the competitive space of dominant DP ecosystem players. The study utilizes the theory of Corporate Aikido as an analytical framework, mapping the strategic elements of overthrowing established value propositions and turning a competitors’ strengths into weaknesses. Our findings indicate that privacy- and security-awareness, empowerment and inclusivity, premium quality and curation, open source and free access, uncensored, transparent and decentralized platforms as well as ecological and climate-friendly offers shape the landscape of alternative approaches in today’s DP economy. The results are subsequently discussed, yielding managerial implications and future opportunities for DP research.

A1 - Scheeg, Jochen T1 - Coping Practices of Small- and Medium-Sized Enterprises Facing Power Asymmetry in Digital Platform Business JF - Strategic Change N2 - Digital platform (DP) enterprises have risen to the top of the global economy by inverting traditional business models. They earn money through matchmaking, transaction facilitation, and efficient orchestration of other stakeholders' resources. Small- and medium-sized enterprises (SMEs) play a decisive role in this success story: they offer products and services on many leading DPs and thereby feed platform networks as sellers and suppliers. On the other hand, while DPs enable SMEs to reach new customers and outsource costly managerial tasks, many SMEs struggle with the negative consequences of asymmetric power dynamics and dependency risks in platform business. This paper analyzes 14 cases of SMEs that face power asymmetry as DP value providers, unraveling challenges encountered and coping practices employed in this situation. The findings reveal that power asymmetry between dominant DPs and SMEs creates significant challenges, including exploitative relationships, loss of autonomy, surveillance pressures, and devaluation of SME contributions, while SMEs cope through disintermediation, multi-homing, individual resistance tactics, and striving for more equitable DP models. Moreover, three relationality types are identified: DPs being SMEs' “partners,” “tools,” and “necessary evil.” This article offers a new perspective on boundaries of SME strategies in the DP economy and contributes with empirical insights to the advancing field of entrepreneurial platform research.
