Endogenous growth through knowledge spillovers in entrepreneurship: An empirical test [PDF]

Endogenous growth theory is based on the notion that technological knowledge stimulates growth, yet the micro foundations of this process are rarely investigated and remain obscure.

The photoswitchable cannabinoid azo‐HU308 enables optical control of Ca2+ dynamics in INS‐1 β‐cells via off‐target effects on TRPC channels

FEBS Open Bio, EarlyView.
Light activation of the photoswitchable cannabinoid ligand azo‐HU308 triggers Ca2+ influx in pancreatic β‐cells through TRPC channels, independent of CB2 cannabinoid receptors. This reveals a non‐GPCR pathway for cannabinoid modulation of β‐cell Ca2+ dynamics and establishes azo‐HU308 as an optical tool to study cannabinoid signaling through TRP ...

Is the natural rate of growth exogenous?

PSL Quarterly Review, 2000
In mainstream growth theory, including endogenous growth theory, the naturalrate of growth as defined by Harrod, is still treated as exogenous. In practice, however, both the growth of the labour force and the growth of labour productivity are endogenous

Endogenous Growth and Environmental Kuznets Curve: Lessons from FDI Impact on Economic Growth in Sub-Saharan Africa

Journal of Enterprise and Development
Purpose: This study aims to determine the influence of Foreign Direct Investments (FDI) on economic growth in Sub-Saharan Africa (SSA). It examines the endogenous growth theory and the Environmental Kuznets Curve (EKC) theory, and how they relate to the

Product variety, product quality, and evidence of Schumpeterian endogenous growth: a note [PDF]

Using US manufacturing industry data, this paper re-examines empirical evidence of first- and second-generation Schumpeterian models of endogenous growth focusing on innovation (patent) quality.

Naked cuticle is essential for Drosophila wing development beyond Wingless signaling

FEBS Open Bio, EarlyView.
Naked cuticle (Nkd), a Wnt signaling inhibitor, assumes extensive roles in Drosophila wing development. Overexpressing Nkd causes smaller, crumpled wings, while also perturbing multiple signaling pathways and developmental genes. A specific region (R1S) is critical for Nkd's function as a signaling integrator, offering new insights for studying its ...

Critica della teoria neoclassica della crescita e della distribuzione (A Critique of the Neoclassical Theory of Growth and Income Distribution)

Moneta e Credito, 2012
The paper surveys the main theories of income distribution in their relationship with the theories of economic growth. First, the Classical approach is considered, focusing on the Ricardian theory. Then the neoclassical theory is discussed, highlighting

Strictly Endogenous Growth with Non-renewable Resources Implies an Unbounded Growth Rate. [PDF]

Conventional endogenous growth theory relies on the assumption of constant returns to ”broad capital”. As Solow pointed out, the strength of this assumption is revealed by recognizing that even the slightest touch of increasing returns creates explosive ...

Establishment of a coculture system for Porphyromonas gingivalis and head and neck squamous cell carcinoma using spheroid culture and LATS inhibition

FEBS Open Bio, EarlyView.
We established a spheroid coculture system enabling viable Porphyromonas gingivalis–HNSCC interactions under normoxic conditions. Inhibition of LATS1/2 maintains tumor cells in an undifferentiated state, which may promote spheroid growth and create a more permissive environment for bacterial persistence.

Imitation trap and catch-up: a benchmark model based on horizontal innovation theory [PDF]

China Political Economy
PurposeThe paper introduces the concept of the “imitation trap” to describe a state where economies remain reliant on technological imitation and fail to transition to growth driven by independent innovation.
