This study aims to explore the rise of virtual specialty care startups and understand how the ventures leverage digital services to create a new market space. Given the high level of competition in an established industry like health care, the authors investigate the business models and competitive strategies of leading virtual specialty care startups with unicorn status (i.e. emerging, current and exited unicorns).

The authors performed an analysis of Crunchbase data to examine whether rising virtual care ventures target specialty care. They focused on companies from the USA, Europe and Asia-Pacific. The identified virtual specialty care ventures were investigated in-depth via a multiple case study. By reviewing corporate websites, Crunchbase data and media coverage, the authors analyzed the ventures’ business models and competitive strategies.

This study demonstrates that even in established and highly competitive markets such as health care, managers and entrepreneurs can still leverage digital services to unlock new market spaces. The data analysis reveals that virtual care startups target the field of specialty care. They create a new market space by focusing on fast access to services, personalization, measurable outcomes and affordability. The majority of investigated companies pursues a platform-based business model approach.

In the context of an established industry like health care, this study gives insights into a new generation of virtual specialty care ventures. By investigating the ventures’ business models and competitive strategies, the authors advance a young field of research.

This study aims to investigate whether health insurers are transforming from pure payers into ecosystem-based health service companies. The authors discuss the findings’ impact on health insurers’ business model approach and their sources of competitive advantage.

The authors conducted a multiple case study of 25 incumbent and rising health insurers from the USA, Europe and Asia-Pacific. The selection of firms was based on databases from Forbes, S&P Global Market Intelligence and Crunchbase. By performing a review of financial reports, app descriptions, corporate websites and media coverage, the authors analyzed health insurers’ digital service offerings and underlying strategic approaches for providing those services.

This study demonstrates that major health insurers are transforming into ecosystem-based health service companies. They expand the traditional insurance value chain by offering value-adding health services along the patient journey. The analysis results are summarized in a table displaying 18 digital service categories along core patient journey phases with corresponding examples of health insurers and underlying strategic approaches.

The role of digital services and ecosystems has been explored for many industries. This study investigates this subject area with a focus on the health insurance sector, advancing a young field of research. The analysis gives insights into the latest digital service offerings and strategic approaches of an internationally diverse set of incumbents and rising ventures.

This article examines the multiple ways in which Hannah Arendt’s thought arose historically and in international context, but also how we might think about history and theory in new ways with Arendt. It is commonplace to situate Arendt’s political and historical thought as a response to totalitarianism. However, far less attention has been paid to the significance of other specifically and irreducibly international experiences and events. Virtually, all of her singular contributions to political and international thought were influenced by her lived experiences of, and historical reflections on, statelessness and exile, imperialism, transnational totalitarianism, world wars, the nuclear revolution, the founding of Israel, war crimes trials, and the war in Vietnam. Yet, we currently lack a comprehensive reconstruction of the extent to which Arendt’s thought was shaped by the fact of political multiplicity, that there are not one but many polities existing on earth and inhabiting the world. This neglect is surprising in light of the significant “international turn” in the history of thought and intellectual history, the growing interest in Arendt’s thought within international theory and, above all, Arendt’s own unwavering commitment to plurality not simply as a characteristic of individuals but as an essential and intrinsically valuable effect of distinct territorial entities. The article examines the historical and international context of Arendt’s historical method, including her critique of process- and development-oriented histories that remain current in different social science fields, setting out and evaluating her alternative approach to historical writing.

The magnetic properties of CoAl_2−2xCo_2xO₄ for 0 ≤ x ≤ 1 are studied. The values of the nearest neighbour (J₁), next‐nearest neighbour (J₂), intra‐plane (J_aa) and inter‐plane (J_ab,J_ac) exchange interactions are calculated by the mean field theory for ordered region and by the probability law adapted of the nature of dilution problem in A‐spinel lattice in spin glass region. The high‐temperature series expansions have been applied in the CoAl_2−2xCo_2xO₄ systems, combined with the Padé approximants method, to determine the Néel temperature T_N (K) or freezing temperature T_SG (K) in the range 0 ≤ x ≤ 1. The critical exponents associated with the magnetic susceptibility (y) and the correlation lengths (v) are deduced in the range ordered 0.3 ≤ x ≤ 1. The obtained values of y and v are insensitive to the dilution ratio x and may be compared with other theoretical results based on 3D Heisenberg model.

To treat water pollution, especially the contamination resulted from organic dyes has aroused significant attention around the world, this study aims to prepare the metal organic framework (MOF) materials hybridizing with poly(p-phenylene terephthalamide) (PPTA) by means of a facile refluxing method and to systematically investigate adsorption performance for anionic dye Congo red as target molecule from aqueous solution.

The MOF materials hybridized by PPTA were fabricated by virtue of a facile refluxing method, characterized by thermogravimetric analysis, X-ray powder diffraction, Fourier transform infrared and pore structure.

The results showed that pseudo-second-order kinetic model could better describe the adsorption process for all the four materials, whereas Elovich model also fitted the process for the hybrid materials with PPTA. Adsorption isotherm analyses indicated that Langmuir isotherm could be used to describe the adsorption process. Introduction of appropriate amount of PPTA could enhance the adsorption affinity of the MOF materials for Congo red, and the maximum adsorption capacity could reach as high as 1,053.41 mg/g while that of the MOF material without PPTA was 666.67 mg/g, indicating introduction of PPTA could change the microenvironment of the MOF materials and increase the adsorption sites, leading to high adsorption efficiency.

The microstructure of MOF hybridized materials in detail is the further and future investigation.

This study will provide a method to prepare MOF materials with high efficiency to treat anionic dyes like Congo red from aqueous solution.

Owing to the special characteristics of PPTA and similar to carbon tube, PPTA was introduced into MOF material to increased corresponding water stability. Because of aromatic ring and amide group on the surface of PPTA, the adsorption efficiency of the hybridized MOF material with appropriate amount of PPTA was greatly enhanced.
