FDI and Performance: A Comparative Analysis Between Emerging and Developed Economies

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT This study investigates the nuanced relationship between foreign direct investment (FDI) and firm performance, addressing the heterogeneity of FDI's impact across countries with different levels of development. While FDI is widely recognized as a catalyst for economic growth, technology transfer, and enhanced competitiveness, particularly in ...

Errors in reconstruction of dichroic X‐ray orientation tomography due to polarization rotation of the incident beam

open access: yesJournal of Synchrotron Radiation, EarlyView.
Linear dichroic X‐ray tomography is a technique in which the linear dichroism of anisotropic materials is used to image crystal orientation in three dimensions. We show that the reconstruction of tomograms is subject to errors due to the change in polarization on propagation through the material and propose strategies for mitigating these effects ...

Almost everywhere convergence of series in $L^1$ [PDF]

open access: yesProceedings of the American Mathematical Society, 2005
Let \(T\) be a measure preserving transformation on the probability space \((X, \mathcal{B}, \mu).\) The main result of the author is an answer to a question raised by \textit{J. Rosenblatt} [Math. Ann. 280, No. 4, 565--577 (1988; Zbl 0618.60029)]. He proves the existence of a sequence of scalars \(c_i\) such that \(\sum_{i=1}^{\infty}| c_i| = \infty\)

Imagination in Critical Theory: Utopia, Ideology, Aesthetics

open access: yesConstellations, EarlyView.
ABSTRACT This article explores the role of imagination in critical theory, addressing its conceptual ambiguity and its synthesis of three distinct but interrelated strands. The first, rooted in Freud's theory, sees imagination as wish‐fulfillment—necessarily unreal yet foundational to utopian thought.

Improved endpoint bounds for the lacunary spherical maximal operator

open access: yes, 2017
We prove new endpoint bounds for the lacunary spherical maximal operator and as a consequence obtain almost everywhere pointwise convergence of lacunary spherical means for functions locally in $L\log\log\log L(\log\log\log\log L)^{1+\epsilon}$ for any $\

Disclosure, disbelief, enclosure: listening with precarious kids in London Témoignage, incrédulité, enfermement: écouter les enfants en situation de précarité à Londres

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article interrogates the role of testimonial disclosure as a mechanism of access and a barrier to visibility for marginal people, particularly adolescents, in the UK. Drawing on ethnographic fieldwork conducted between 2021 and 2024 in alternative educational provision (AP), as well as in English for Speakers of Other Languages (ESOL) classes ...

Are physiological oscillations physiological?

open access: yesThe Journal of Physiology, EarlyView., 2023
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Fixed Points of Self-Mappings with Jumping Effects: Application to Stability of a Class of Impulsive Dynamic Systems

open access: yesMathematics
This paper studies the boundedness and convergence properties of the sequences generated by strict and weak contractions in metric spaces, as well as their fixed points, in the event that finite jumps can take place from the left to the right limits of ...

Almost everywhere convergence of convolution products

open access: yes, 2011
Let $(X,\mathcal{B},m, )$ be a dynamical system with $\ds (X,\mathcal{B},m)$ a probability space and $\ds $ an invertible, measure preserving transformation. The present paper deals with the almost everywhere convergence in $\ds{L}^1(X)$ of a sequence of operators of weighted averages.
