Determination of β-Estradiol by Surface-Enhance Raman Spectroscopy (SERS) Using a Surface Imprinted Methacrylate Polymer on Nanoporous Biogenic Silica

Abstract: A phytoplankton derived nanoporous biogenic silica (BS) scaffold grafted with polymethacrylate β-estradiol molecularly imprinted polymers (MIP) film (MIP@BS) is reported as a selective platform for...

Reporting results back in Health and demographic surveillance systems (HDSS): an ethical requirement and a strategy for improving health behaviours

Abstract: This paper addresses the issue of reporting results back in Health and demographic surveillance systems (HDSS). In these particular research platforms, populations are constantly solicited through the longitudinal demographic follow-up and additional surveys. Therefore, reporting results back directly to participants should be considered as a strong ethical requirement. However, like in most health oriented research, results are mostly disseminated among decision makers and local authorities. Therefore, HDSS residents increasingly question the objectives of these studies. Using a participatory approach, 3 days were organized in 2015 to report back findings based on 50 years of research on population, health and environment in the Niakhar HDSS in Senegal. Drawing from the evaluation conducted among a sample of participants to the event, we show that beyond the ethical dimension, such activities may also contribute to change populations’ attitudes to research practices and further influence individuals’ health behaviors at the local level.

Crossed products of operator algebras: applications of Takai duality

Abstract: Let $(\mathcal G, \Sigma)$ be an ordered abelian group with Haar measure $\mu$, let $(\mathcal A, \mathcal G, \alpha)$ be a dynamical system and let $\mathcal A\rtimes_{\alpha} \Sigma $ be the associated semicrossed product. Using Takai duality we establish a stable isomorphism \[ \mathcal A\rtimes_{\alpha} \Sigma \sim_{s} \big(\mathcal A \otimes \mathcal K(\mathcal G, \Sigma, \mu)\big)\rtimes_{\alpha\otimes {\rm Ad}\: \rho} \mathcal G, \] where $\mathcal K(\mathcal G, \Sigma, \mu)$ denotes the compact operators in the CSL algebra ${\rm Alg}\:\mathcal L(\mathcal G, \Sigma, \mu)$ and $\rho$ denotes the right regular representation of $\mathcal G$. We also show that there exists a complete lattice isomorphism between the $\hat{\alpha}$-invariant ideals of $\mathcal A\rtimes_{\alpha} \Sigma$ and the $(\alpha\otimes {\rm Ad}\: \rho)$-invariant ideals of $\mathcal A \otimes \mathcal K(\mathcal G, \Sigma, \mu)$. Using Takai duality we also continue our study of the Radical for the crossed product of an operator algebra and we solve open problems stemming from the earlier work of the authors. Among others we show that the crossed product of a radical operator algebra by a compact abelian group is a radical operator algebra. We also show that the permanence of semisimplicity fails for crossed products by $\mathbb R$. A final section of the paper is devoted to the study of radically tight dynamical systems, i.e., dynamical systems $(\mathcal A, \mathcal G, \alpha)$ for which the identity ${\rm Rad}(\mathcal A \rtimes_\alpha \mathcal G)=({\rm Rad}\:\mathcal A) \rtimes_\alpha \mathcal G$ persists. A broad class of such dynamical systems is identified.

Towards developing a business performance management model using causal latent semantic analysis

Abstract: Business performance management (BPM) helps organisations achieve improved effectiveness and competitiveness by bridging the gap between strategy and execution. Though several industry-specific practitioner BPM frameworks exist, there is little research in the academia on BPM. This study fills this void by developing and testing a generic BPM model using causal latent semantic analysis on textual data obtained from both practitioner and academic sources. The BPM model developed in this study provides a structure for enhancing responsiveness and flexibility because it embodies the process of managing an organisation's strategy. Since the BPM process embodies a closed-loop process with the objective of continuously adjusting business strategies, it helps organisations to enhance their agility. Therefore, with the implementation of the BPM framework, organisations can quickly adapt to changes. This study posits that the proposed BPM model will help managers create an agile organisation that is capable of developing and increasing competitive advantage.
