Unpacking the Role of Higher Education Institutions in Accelerating Women’s Progressive Education in Kenya
Authors: Odhong Emily A. , Achieng Cynthia O. 
Published: May 2024

Due to unprecedented global challenges, labour market dynamics, and uncertainties, higher education institutions have no options but to adopt new approaches to enhance adaptability. In Kenya, despite many efforts made to accelerate women's empowerment, only 29 percent of women between the ages of 15 and 49 are empowered. The universities have a unique capacity and potential to develop skills, foster knowledge, and mobilize educational resources. Hence, accelerating an inclusive socio-economic recovery starts with a solid foundation of human capital which entails: health, education, skills, jobs, and growth to boost progressive education. The significance of the study is to: expand access to progressive quality education for girls and women; inform policies; enhance capacity to upscale women’s holistic learning and most importantly promote resilience and innovativeness among higher education institutions to emerge stronger. The main objective of the study was to analyse the role of higher education institutions in accelerating women’s progressive education in Kenya. The study was anchored on John Dewey's theory and women's empowerment framework, which cuts across and support both dependent and independent variable. The study adopted a mixed-method research design and, a pragmatic and constructive research philosophy. The researcher adopted a triangulation approach in sampling techniques where stratified, purposive, and random sampling techniques were applied. The study sample size comprised 129 - degree students and 26 lecturers. Questionnaires were adopted as the data collection tool. Based on the regression results, the study findings reveal that the R-squared is 0.62, the Adjusted R-squared is 0.61, the F-statistic of 31.94, and a p-value of 0.0000. This implies that the model explains 61% of changes in women’s progressive education. The study concludes that the public-private nexus, blended learning, digitalization, and student retention explain a 61% percent change in women’s progressive education. The study recommends: First, strengthening of public-private nexus through institutional industry linkages, upscaling support through adequate funding of women’s education, and considering Students as Partners in their learning. Second, embracing a blended learning approach to reduce the dropout rate of female students and upscale women empowerment through the integration of ICT skills training. Third, institutions should commit adequate resources to promote effective digitalization and improvement in ICT infrastructure that facilitates learning and is user-friendly to lecturers, learners, and administrators. Lastly, promoting students’ retention through mentorship, semester check-ins, workshops, and effective lecturers, to enhance student enrollment and acceleration which increases completion rate and school-to-work transition, and embracing transformative and sustainable leadership.

Authors: GOYAL A.K. , Garg Gaurav Kumar 
Published: May 2024

The study of non-contraction mapping concerning the existence of fixed points draws attention of various authors in non-linear analysis. Gahlar [6] introduced the concept of 2- Banach spaces. Badshah and Gupta [3] , Yadava, Rajput, Choudhary and Bhardwaj [26] proved some results on fixed point in 2-Banach spaces. Recently Yadava,Rajput, Bhardwaj [25] proved a result on fixed point in 2- Banach spaces for non- contraction mappings. In this paper we prove some common fixed point theorems for non-contraction mappings in 2-Banach spaces, which contains new rational expressions.

Mélancolie, ironie, fureur ; modernité de Baudelaire
Authors: AGOSTINHO Larissa Drigo 
Published: May 2024

Il s’agit ici d’analyser trois affects qui parcourent la poésie baudelairienne et les rapports qu’ils établissent entre eux. Nous examinerons d’abord la théorie baudelairienne du beau et de la modernité pour ensuite réfléchir, à partir de Walter Benjamin, sur le rapport entre l’antiquité et la modernité. C’est ici que le rapport entre mélancolie, ironie et fureur peut être analysé surtout si nous prenons en compte le rapport entre Baudelaire et la société de son temps. La relevance de cet article est qu’il met en lumière la porté critique de l’ironie et met l’emphase sur la procédure du choc comme forme de pointer le caractère innommable de l’expérience.
Abstract
The aim here is to analyze three affects that permeate Baudelaire's poetry and the relations they establish between them. We will first examine the Baudelaire's theory of beauty and modernity and then reflect, based on Walter Benjamin, on the relationship between antiquity and modernity. It is here that the relationship between melancholy, irony and fury can be analyzed especially if we take into account the relationship between Baudelaire and the society of his time. The relevance of this article is that it highlights the critical scope of irony and emphasizes the procedure of shock as a way of pointing out the unspeakable character of experience.

Static and dynamic mechanical properties of flame‐retardant copolyester/nano‐ZnCO3 Composites
Authors: Liu Haiming , Wang Rui , Xu Xi 
Published: April 2011

AbstractNovel phosphorus‐containing copolyester nanocomposites were synthesized by in situ polymerization with 2‐carboxyethyl(phenylphosphinic) acid (CEPPA) and nano‐ZnCO3. The flame retardancy and static and dynamic mechanical properties of poly(ethylene terephthalate) (PET)/nano‐ZnCO3 composites and phosphorus‐containing copolyester/nano‐ZnCO3 composites were evaluated with limiting oxygen index measurements, vertical burning testing (UL‐94), a universal tensile machine, and a dynamic mechanical analysis thermal analyzer. The phosphorus‐containing copolyester nanocomposites had higher limiting oxygen indices (ca. 32%) and a V0 rating according to the UL‐94 test; this indicated that nano‐ZnCO3 and CEPPA greatly improved the flame retardancy of PET. The static mechanical test results showed that the breaking strength, modulus, and yield stress of the composites tended to increase with increasing nano‐ZnCO3 content; when 3 wt % nano‐ZnCO3 was added to PET and the phosphorus‐containing copolyester, the breaking strength of the composites was higher than that of pure PET. Dynamic mechanical analysis indicated that the dynamic storage modulus and loss modulus of the PET composites increased markedly in comparison with those of pure PET. However, the glass‐transition temperatures associated with the peaks of the storage modulus, mechanical loss factor, and loss modulus significantly decreased with the addition of ZnCO3 and CEPPA. The morphologies of the composites were also investigated with scanning electron microscopy, which revealed that nano‐ZnCO3 was dispersed homogeneously in the PET and copolyester matrix without the formation of large aggregates. In addition, the interfacial adhesion of nano‐ZnCO3 and the matrix was perfect, and this might have significantly affected the mechanical properties of the composites. © 2011 Wiley Periodicals, Inc.

Authors: Banks David , Petralia Francesca , Wang Shouqiang 
Published: April 2011

AbstractAdversarial risk analysis (ARA) offers a new solution concept in game theory. This paper explores its application to a range of simple gambling games, enabling comparison with minimax solutions for similar problems. We find that ARA has several attractive advantages: it is easier to compute, it takes account of asymmetric information, it corresponds better to human behavior, and it reduces to previous solutions in appropriate circumstances.

Urea‐, Squaramide‐, and Sulfonamide‐Based Anion Receptors: A Thermodynamic Study
Authors: Amendola Valeria , Fabbrizzi Luigi , Mosca Lorenzo , Schmidtchen Franz‐Peter 
Published: April 2011

AbstractIn this work, we compare the anion‐binding capabilities of receptors 1–5, characterized by similar structures, but possessing different hydrogen‐bond‐donor moieties (urea, squaramide, and sulfonamide). The presence of chromophoric substituents on the receptor’s skeleton allowed the determination of association constants by performing UV/Vis titrations with the investigated anions on solutions of the receptors in pure acetonitrile. Additional quantitative studies of the anion‐binding properties of receptors 1–5 were performed by isothermal titration calorimetry (ITC). The experimental results indicated that 1 and 2 formed 1:1 hydrogen‐bonded complexes with most of the anions investigated. In the case of receptors 3–5, the formation of the 1:1 adduct was observed only with anions of low basicity (i.e., chloride, bromide, iodide, and hydrogen sulfate). With more basic anions (i.e., acetate and dihydrogen phosphate), both spectrophotometric and ITC titrations accounted for the deprotonation of the sulfonamide group, involving the formation of the conjugated base of the receptor.
Image‐derived, three‐dimensional generative models of cellular organization
Authors: Peng Tao , Murphy Robert F. 
Published: April 2011

AbstractGiven the importance of subcellular location to protein function, computational simulations of cell behaviors will ultimately require the ability to model the distributions of proteins within organelles and other structures. Toward this end, statistical learning methods have previously been used to build models of sets of two‐dimensional microscope images, where each set contains multiple images for a single subcellular location pattern. The model learned from each set of images not only represents the pattern but also captures the variation in that pattern from cell to cell. The models consist of sub‐models for nuclear shape, cell shape, organelle size and shape, and organelle distribution relative to nuclear and cell boundaries, and allow synthesis of images with the expectation that they are drawn from the same underlying statistical distribution as the images used to train them. Here we extend this generative models approach to three dimensions using a similar framework, permitting protein subcellular locations to be described more accurately. Models of different patterns can be combined to yield a synthetic multi‐channel image containing as many proteins as desired, something that is difficult to obtain by direct microscope imaging for more than a few proteins. In addition, the model parameters represent a more compact and interpretable way of communicating subcellular patterns than descriptive image features and may be particularly effective for automated identification of changes in subcellular organization caused by perturbagens. © 2011 International Society for Advancement of Cytometry.

AbstractMicroRNAs (miRNAs), small non‐coding RNA molecules that post‐transcriptionally regulate gene expression, are known to play key roles in regulating immune responses and autoimmunity. We investigated miR‐146a expression in Sjögren's syndrome (SjS) patients as well as in the SjS‐prone C57BL/6.NOD‐Aec1Aec2 mouse model, to elucidate its involvement in SjS pathogenesis. Expression of miR‐146a was examined in the PBMCs of 25 SjS patients and ten healthy donors, as well as in PBMCs, salivary and lacrimal glands of SjS‐prone mice and WT C57BL/6J mice. Functional assays using THP‐1 human monocytes were conducted to determine the biological roles of miR‐146a in innate immunity. Expression of miR‐146a was significantly increased in SjS patients compared with healthy controls, and was upregulated in the salivary glands and PBMCs of the SjS‐prone mouse at both 8 wk (prior to disease onset) and 20 wk (full‐blown disease) of age. More importantly, functional analysis revealed roles for miR‐146a in increasing phagocytic activity and suppressing inflammatory cytokine production while migration, nitric oxide production and expression of antigen‐presenting/costimulatory molecules are not affected in human monocytic THP‐1 cells. Taken together, our data suggest that abnormal expression/regulation of microRNAs in innate immunity may contribute to, or be indicative of, the initiation and progression of SjS.

AbstractT cells exercise their full impact on target cells through a combination of secreted cytokines. The recently described T helper cell subset Th22 is characterized by a combinatorial secretion of IL‐22 and TNF‐α. Here, we demonstrate that IL‐22 increases the TNF‐α‐dependent induction and secretion of several immune‐modulatory molecules such as initial complement factors C1r and C1s, antimicrobial peptides S100A7 and HBD‐2 (human β defensin 2), and antimicrobial chemokines CXCL‐9/‐10/‐11 in primary human keratinocytes. The synergism of IL‐22 and TNF‐α is transmitted intracellularly by MAP kinases and downstream by transcription factors of the AP‐1 family. The induction of innate immunity is relevant in an in vitro infection model, where keratinocytes stimulated with Th22 supernatants or recombinant IL‐22 plus TNF‐α effectively inhibit the growth of Candida albicans and maintain survival of epithelia. Accordingly, the combinatorial stimulation of keratinocytes with IL‐22 and TNF‐α most efficiently conserves the integrity of the epidermal barrier in a three‐dimensional skin infection model as compared with IFN‐γ, IL‐17, IL‐22 or TNF‐α alone. In summary, we demonstrate that IL‐22 and TNF‐α represent a potent, synergistic cytokine combination for cutaneous immunity.
Complex phosphorylation dynamics control the composition of the Syk interactome in B cells

Published: April 2011

AbstractSpleen tyrosine kinase Syk provides critical transducer functions for a number of immune cell receptors and has been implicated in the generation of several forms of leukemias. Catalytic activity and the ability of Syk to interact with other signaling elements depend on the phosphorylation status of Syk. We have now identified and quantified the full spectrum of phosphoacceptor sites in human Syk as well as the interactome of Syk in resting and activated B cells by high‐resolution mass spectrometry. While the majority of inducible phosphorylations occurred on tyrosine residues, one of the most frequently detected phosphosites encompassed serine 297 located within the linker insert distinguishing the long and short isoforms of Syk. Full‐length Syk can associate with more than 25 distinct ligands including the 14‐3‐3γ adaptor protein, which binds directly to phosphoserine 297. The latter complex attenuates inducible plasma membrane recruitment of Syk, thereby limiting antigen receptor‐proximal signaling pathways. Collectively, the established ligand library provides a basis to understand the complexity of the Syk signaling network.

Authors: Fenga Paula Gonçalves , Stradiotto Nelson Ramos , Pividori Maria Isabel 
Published: April 2011

AbstractA novel conducting silver nanocomposite (nanoAg‐GEC) material for electrochemical sensing of substituted anilines based on silver nanoparticles is presented. For the first time, the in situ growth of silver hexacyanoferrate nanoparticles (nanoAgHCF) on the surface of the silver nanocomposite electrodes was achieved. The surface morphology of the nanoAg‐GEC electrode modified with hexacyanoferrate (nanoAgHCF‐GEC) was investigated using scanning electron microscopy (SEM) coupled with energy‐dispersive X‐ray spectroscopy (EDX). The electrochemical behaviour of the nanoAgHCF‐GEC electrode towards oxidation and reduction of substituted anilines (procaine and sulfamerazine) was investigated by cyclic voltammetry. The results showed a linear dependence in the concentration range studied for each class of sulfonamides.

Published: April 2011

AbstractA modification of the voltammetric procedure for the determination of uranium in the presence of cupferron using hanging mercury drop electrode is presented. The pulsed potential accumulation was proposed for the minimization of interferences of surface active substances. The calibration plot for U(VI) in the presence of 2 ppm Tritonu X‐100 was linear from 1.7×10−10 to 2.0×10−8 mol L−1 for an accumulation time of 60 s, with correlation coefficient of 0.996. The application of this method was tested in the determination of uranium in certified reference material NASS‐5 and river water samples.
Dynamic interaction of bridge–train system under non‐uniform seismic ground motion

Published: April 2011

AbstractThe probability that an earthquake occurs when a train is running over a bridge in earthquake‐prone regions is much higher than before, for high‐speed railway lines are rapidly developed to connect major cities worldwide. This paper presents a finite element method‐based framework for dynamic analysis of coupled bridge–train systems under non‐uniform seismic ground motion, in which rail–wheel interactions and possible separations between wheels and rails are taken into consideration. The governing equations of motion of the coupled bridge–train system are established in an absolute coordinate system. Without considering the decomposition of seismic responses into pseudo‐static and inertia‐dynamic components, the equations of motion of the coupled system are formed in terms of displacement seismic ground motions. The mode superposition method is applied to the bridge structure to make the problem manageable while the Newmark‐β method with an iterative computation scheme is used to find the best solution for the problem concerned. Eight high‐speed trains running over a multi‐span steel truss‐arch bridge subject to earthquakes are taken as a case study. The results from the case study demonstrate that the spatial variation of seismic ground motion affects dynamic responses of the bridge–train system. The ignorance of pseudo‐static component when using acceleration seismic ground motions as input may underestimate seismic responses of the bridge–train system. The probability of separation between wheels and rails becomes higher with increasing train speed. Copyright © 2011 John Wiley & Sons, Ltd.

AbstractWe present a three‐dimensional thermodynamically‐consistent phenomenological model for the magneto‐mechanical behavior of magnetic shape memory materials featuring a cubic‐totetragonal martensitic transformation. Existence of energetic solutions for both the constitutive relation problem and the three‐dimensional quasi‐static evolution problem are proved. The proposed model reduces to some former one via parameter asymptotics by means of a rigorous Γ‐convergence argument (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
