We extend the spin-boson model of open quantum systems to the regime of quantum 1/𝑓^𝜂 noise characterized by negative exponents of its spectral distribution. Using the numerically exact time-evolving matrix product operator, we find the dynamic regime diagram, including pseudocoherent dynamics controlled by quantum 1/𝑓^𝜂 noise. We determine the dephasing rate and find for it an empirical formula valid at zero temperature. The bath reorganization energy depends on the infrared bath cutoff frequency, revealing an increased sensitivity of the dephasing on the measurement time of an experiment. Our results apply to a qubit as an elementary building block of a quantum computer and pave the way toward a quantum treatment of low-frequency noise in more complex architectures.
Purpose – To advance women’s entrepreneurship research,scholarsrequire a clearer understanding of how, and where, researchers have applied the field’s critical theoretical frameworks, as well as how extant studies have shaped the development ofthe frameworks and field of women’s entrepreneurship. This paper addresses this gap by conducting an integrative literature review (ILR) of Brush et al.’s (2009) 5 M framework article and proposes a conceptualization of 5 M framework research alongside future research directions for the field of women’s entrepreneurship.
Design/methodology/approach – Our study utilizes an ILR to analyze how researchers have leveraged the 5 M framework and what this reveals about its development and role in women’s entrepreneurship research. We draw on Scopus and Google Scholar databases to present a comprehensive review of all publications (n 5 944) that cite Brush et al.’s (2009) article (from 2009 to 2023), focusing on those works (n 5 87) which base their methodological or theoretical approach on the 5 M framework.
Findings – Our ILR reveals that research using the 5 M framework can be conceptualized as consisting of four different layers: the specific contributions made by such research to the development of the 5 M framework itself; the key themes and mechanisms within women’s entrepreneurship addressed by this research; the methodological approaches applied; and the empirical contexts in which the framework dimensions have been employed.
Research limitations/implications – Our study identifies pertinent literature gapsin women’s entrepreneurship and provides pathways for diversifying theory-building in the field.
Originality/value – We analyze a prominent theoretical framework in the field of women’s entrepreneurship. Our analysis shows not only pathways for future women’s entrepreneurship research but also the status of the field and how researchers deal with existing frameworks, thus highlighting opportunities to go beyond the status quo.
Shadows and spotlights: A postfeminist analysis of women innovators’ experiences with (in)visibility
(2025)
Contrary to the notion that innovation is a universally accessible and meritocratic endeavor, concerns persist over not only women innovators’ numerical underrepresentation but also their (in)visibility. Studying innovation as a social context structured by power, we focus on 18 women innovators in innovation-driving environments. While these women appear to symbolize gender equality and embody contemporary postfeminist ideals of individualism, choice, and empowerment, many have simultaneously experienced (in)visibility and navigated unequal power structures throughout their careers. We investigate how these (in)visibility experiences are reconciled with the promises of postfeminism, exploring how postfeminist ideals are interpreted and negotiated by them to make sense of their own (in)visibility. While (in)visibility has traditionally been theorized in relation to norms and gendered power structures, our findings reveal how postfeminist discourses reframe visibility as an individualized, moralized imperative rooted in self-responsibility. Through this lens, we identify four postfeminist sense-making approaches: meritocratic visibility (embodying postfeminist ideologies), retraditionalized visibility (conforming to femininity), self-disciplined visibility (adapting to gender inequality), and collective-oriented visibility (challenging the status quo). These sense-making approaches highlight the various ways in which postfeminist sensibilities shape subjective experiences, often masking structural inequalities and allowing these to persist in contexts that claim to promote equal opportunities, such as the innovation environment. We point to the need for collective rather than individualized action for structural transformation.
Das Nachhaltigkeitsreporting ist und bleibt für viele Unternehmen ein wichtiges, aktuelles und dynamisches Thema - auch politisch gesehen.
Der Studienbericht ist eine Fortführung der im Jahr 2023 durchgeführten empirischen Erhebung zum Stand der digitalen Nachhaltigkeitsberichterstattung in Unternehmen des westlichen Münsterlandes und fand im Rahmen des EFRE-Projekts "DiNaOpt4KMU" statt. Ein Vergleich der Ergebnisse zur ersten Ausgabe zeigt unter anderem, dass ein Großteil der Unternehmen sich im Bereich Nachhaltigkeit positioniert und weiterentwickelt haben. Zudem konnten in der zweiten Auflage Entwicklungen in der Region Westmünsterland aufgezeigt und bewertet werden. Es konnte eine Klassifizierung der teilgenommen Unternehmen in „Neueinsteiger, Einsteigende und Fortgeschrittene“ erfolgen.
Eine weitere Studienauflage ist für das Jahr 2026 in Planung.
In dieser Arbeit wird der Einsatz von Dark LLMs zur Durchführung von OSINT-Recherchen im Rahmen der polizeilichen Gefahrenabwehr und Strafverfolgung in Nordrhein-Westfalen analysiert. Hierfür wird zunächst eine erste wissenschaftliche Definition des Begriffs Dark LLM erstellt. Anschließend werden relevante Dark LLMs vorgestellt, auf deren Gefahren aufmerksam gemacht und geeignete Gegenmaßnahmen erörtert. Danach erfolgt eine rechtliche Einordnung anhand mehrerer Gesetzestexte. Dann wird eine prototypische Entwicklung eines LLMs durchgeführt, welches für OSINT-Recherchen eingesetzt werden kann. Die rechtliche Analyse und die technische Implementierung ergeben, dass der Einsatz eines Dark LLMs in der polizeilichen Arbeit unzulässig ist. Zudem wird ein polizeiliches LLM nach der KI-Verordnung sowohl als Hochrisiko-KI-System als auch als KI-Modell mit allgemeinem Verwendungszweck eingestuft, wodurch sich etliche Pflichten ergeben, die ein LLM in ihrer Funktion einschränken. Trotz dieser Einschränkungen ist ein Einsatz eines solchen LLMs sinnvoll, denn dieses kann viele OSINT-Informationen sekundenschnell zu einer gebündelten Antwort zusammenfassen, was die polizeiliche Arbeit erheblich erleichtert. Durch allgemeines OSINT-Training und die Anbindung weiterer OSINT-Quellen kann die Qualität der Antwort deutlich verbessert werden.

Abstract
This case describes the difficulties of business succession from a successor’s perspective. The case is based on a real metalworking family business in an old industrial region in Germany. The key issues are challenges that, Michelle and Adrian, two second-generation successors within one company, face in teambuilding and finding their own place within the corporation and their team. The case is divided into two parts: Part 1 is a newspaper article about the succession process that points out stereotypes and writing styles in reporting on entrepreneurship/succession in the media. Part 2 is the succession story written from Michelle’s perspective and highlights challenges that female successors face in traditional male-dominated areas, for instance, when it comes to questions of balancing work and family needs. The case addresses issues relating to entrepreneurship and business succession classes, with sociological and psychological overtones.
The aim of this chapter is to address the impact of formal and informal institutions on women’s entrepreneurship and to extend our understanding of issues influencing women-owned businesses and women’s entrepreneurship in the context of a transition economy, such as Georgia. Our work specifically addresses formal institutions, such as governmental initiatives, financial institutions, and business-relevant education. It also addresses informal institutions, such as women’s role in society, the use of informal networks of connections and acquaintances, and gift-giving practices. Drawing on results from an online focus group discussion with women entrepreneurs in Georgia, we provide initial insights into the critical constraints and supporting factors that local women entrepreneurs experience. Based on the interrelation of institutions and women’s entrepreneurship, we conclude that changes in formal institutions do not lead directly to changing informal institutions. Due to the lack of trust in formal institutions, women entrepreneurs are more likely to look for business development solutions outside the official frames, including illegal or unethical means of survival. Nevertheless, increased opportunities – induced by specific entrepreneurship policies and programs – encourage women to enter entrepreneurship. In addition to this, entrepreneurship enables women in Georgia to overcome gender discrimination issues, which is more prevalent in employment relationships in the local labor market than in entrepreneurial activities.
The Integration of Refugees in Small and Medium-Sized Enterprises (SMEs): Case Studies from Practice
(2024)
Abstract
With the increasing number of refugees seeking protection and a new home in Germany, our society faces the task of optimally integrating those refugees. This includes integration into the labor market. This chapter deals with the integration of refugees into small and medium-sized enterprises (SMEs). We explore why SMEs choose to integrate refugees into their business, what opportunities they see in it, what challenges integration brings, and what management considers as success factors of a successful integration. The results show that a successful integration is based on a combination of the individual commitment of the refugees, the acceptance and support of the management and workforce in the company as well as clear, reliable institutional framework conditions.
Mit der hier vorliegenden Toolbox stellen wir die Ergebnisse des dreijährigen, durch das Bundesministerium für Bildung und Forschung geförderten, Forschungsprojektes „Westfälische Erfinderinnen“ vor. Das Hauptziel des Projektes umfasste dabei, in den Regionen Ruhrgebiet und Münsterland Innovatorinnen zu identifizieren und die regionalen Mechanismen der (Un-)Sichtbarkeit von Innovatorinnen zu untersuchen und zu verstehen. Aufbauend auf den gewonnenen Erkenntnissen wurden ausgewählte Innovatorinnen zielgerichtet mit unterschiedlichen Kommunikationswerkzeugen ins Licht der regionalen Öffentlichkeit gerückt, um so das gesellschaftliche Bewusstsein für die Vielfalt von Innovationsprozessen und die Rolle von Innovatorinnen zu stärken. Die hier vorliegende Toolbox soll Hochschulen und andere zentrale Akteur:innen in weiteren Regionen ermutigen und anleiten, ihre Innovatorinnen zu finden, zu unterstützen und weithin
sichtbar zu machen.
