Customer Lifetime Value: Dimensionalities and Conceptual Connections
Full text linkCustomer Lifetime Value (CLV) has a strong relationship to customer satisfaction and firm profitability . This review indicates that once such a relationship is developed and cemented, multiple benefits accrue to the brand and the firm. The review lays the groundwork for further studies of CLV, especially in the emerging economies

Situating Media Literacy with a Theory of Change: “Mapping JMLE”
Full text linkThis article uses a theory of change to identify the difference media literacy work makes to people’s lives, based on work published in the Journal of Media Literacy Education in 2024. This is a pilot study stage towards a global field mapping, aiming to make the case for media literacy as an essential element in the health of the communication ecosystem (forthcoming, 2025).
This is an exploratory pilot sharing provisional evidence, but this is the point of the the broader work this article is a part of which seeks to is describe how media literacy can make a difference to people’s lives and to the health of the communication ecosystem, in particular ways but also to help us in the field to be more measured and more humble about what we have overclaimed, where the evidence is generally provisional, or where the broader conditions and imperatives mean the work we do cannot make the differences we desire.
The idea is we learn to claim less, to change more
Multicore SPION Clustering within Poly(amino acid) Corrals for Enhanced MRI Contrast and Drug Release
No full textSuperparamagnetic iron oxide nanoparticle (SPION) clusters produce localized magnetic field inhomogeneities that enhance negative contrast in magnetic resonance imaging (MRI). It is shown that high transverse relaxivity (r2) can be obtained by clustering hydrophobic SPIONs with an average core diameter of ≈7 nm via self-assembly with amphiphilic polyethylene glycol-b-poly(L-Leucine) block copolymers, PEGn-b-p(L-Leu)m, where the PEG chains are terminated by methoxy (CH3O-PEGn) or hydroxyl groups (HO-PEGn). Clusters ranging from 65 to 85 nm in diameter are formed by polymer coating and stabilization of hydrophobic SPION aggregates and yield high r2 values ranging from 226 to 342 s−1 mm Fe−1 with negligible longitudinal relaxivity (r1) and high saturation magnetization near that of bulk maghemite. Polymer composition determines the critical micelle concentrations, notably the length of the hydrophobic segment, and the extent of hydrophobic drug loading. However, it does not significantly impact the size of the SPION cluster assemblies, their magnetic relaxivity, or their drug release, whether passive or during pulsed, intermittent magnetic stimulation. This work demonstrates that the self-assembled amphiphilic block copolymer-based micelles can be used to enhance the colloidal and magnetic relaxivity behavior of SPION clusters while providing variable drug loading and the opportunity for end-group functionalization
Research Advances on Foreign Portfolio Investments: A Bibliometric and Thematic Analysis
No full textForeign portfolio investments have been at the center of research in the finance, economics, and international business domains since the early 1990s when developing economies started to relax their capital account and allowed the entry of foreign investments. Over the years, various macroeconomic (country-specific and global), firm-specific, and quality factors have been studied as determinants in relation to these flows, Still, there is no consensus regarding which factor influences more than the others. This paper uses bibliometric analysis to understand the existing literature to build a solid conceptual base in this research topic. For this study, bibliometric data of 731 articles and reviews from 1991-2022 were extracted from the Scopus database, and bibliometric procedures were applied. First, performance analysis is conducted on the basis of chronological and spatial distribution, influential documents, journal productivity, and eminent authors. Second, scientific mapping on co-citation and keyword occurrence with VOSviewer is done, followed by the thematic content analysis. The study concludes with a discussion on the outcomes of the applied procedures and sheds light on the future scope of research
