Effects of Market Upgrading Temporary Relocation on Livelihoods of PAPs in Juja Market in Kiambu County, Kenya
Authors: Wanjiku Wangui Josphine , Kiprono Bor Eric , Murenga Hadija
Published: November 2024

This paper utilizes data from an MA Thesis on the effects of market upgrading temporary relocation on the livelihoods of Project Affected Persons (PAPs) during the construction of Juja Market in Kiambu County, Kenya. The study is driven by the idea that proper relocation and resettlement of PAPs can mitigate livelihood losses during infrastructural projects, which are vital for economic growth. Kenya is actively enhancing policies and legal frameworks to protect PAPs' interests during resettlement. The study had three objectives: to analyze the effects of market upgrading temporary relocation on PAPs' livelihoods in Juja Market, to examine PAPs' participation in relocation plans, and to assess the impact of relocation restoration packages on minimizing livelihood losses during the market's construction. It was grounded on Sustainable Livelihood Theory and the Impoverishment Risk and Reconstruction Model, involving 124 respondents selected through simple random and purposive sampling. Data analysis used descriptive and inferential statistics. Findings indicate that PAPs faced decreased sales, insufficient trading space, and disrupted networks due to relocation. The primary reason for increased livelihood losses was the government's inadequate preparation and lack of thorough engagement with affected individuals. The study suggests the county government should establish well-equipped, strategically located temporary sites to support traders, enhance transparent communication channels for stakeholder participation, and create participatory forums for co- designing and implementing restoration strategies.

Published: November 2024

Numerous contributors share social problem ideas through open innovation. However, manually analyzing and processing many ideas, extracting information, and identifying expert ideas is difficult. Natural language processing can analyze and process crowd ideas. Our solution outsources creative tasks to crowds and automatically processes ideas. After processing unstructured texts, our solution analyzes text dependencies to extract syntactic sets. The third step, named entity recognition, detects proper names, organization names, locations, countries, etc. in texts. Key term extraction summarizes a text's meaning in the most useful key terms. Next, we find the most important sentences in texts to summarize ideas. Our sixth step extracts text patterns using the previous steps' results. The final step is identifying expert idea sources based on crowd idea patterns. We prove our method works in two studies. First, we compared named entity extraction and syntactic sets to human judgment. Second, we assessed key term extraction to a natural language processing API. Finally, we asked an economics expert to identify expert ideas in web form responses and compared our results with an online API this contributor used. Our method for textual data exploration produces promising results.
An empirical study on web API usability: The consumer-developer perspective
Authors: Machini Ariel , Casas Sandra
Published: November 2024

The ease with which web APIs facilitate access to diverse resources and services has led to their widespread adoption, consequently giving rise to a new business paradigm: the “API economy”. Given this, usability has become a pivotal attribute for API adoption, and within a competitive market, it merits detailed investigation. This exploratory study presents the findings of a survey targeting both consumers and developers of web APIs. The primary objectives of this survey were (1) to ascertain how respondents perceive various usability factors and (2) to identify potential correlations between specific characteristics of participant profiles and their expressed opinions. To fulfill these objectives, descriptive statistical parameters and independence tests were employed. Results indicate that documentation is regarded as the most influential factor on usability, while the quantity of consecutive parameters of the same type is perceived as the least influential. Furthermore, the findings reveal that expert opinions do not deviate significantly from those of non-experts, and that a respondent's experience as a software developer and with web APIs can influence their perceptions regarding certain factors.
Simulating Short Gamma-Ray Burst Jets in Realistic Late Binary Neutron Star Merger Environments
Authors: Pais Matteo , Piran Tsvi , Kiuchi 木内 Kenta 建太 , Shibata 柴 Masaru 田大
Published: November 2024

The electromagnetic emission and the afterglow observations of the binary neutron star merger event GW170817A confirmed the association of the merger with a short gamma-ray burst (GRB) harboring a narrow (5°–10°) and powerful (1049–1050 erg) jet. Using the 1 s long neutrino-radiation general relativistic MHD simulation of coalescing neutron stars of K. Kiuchi et al., and following the semi-analytical estimates of M. Pais et al., we inject a narrow, powerful, unmagnetized jet into the post-merger phase. We explore different opening angles, luminosities, central engine durations, and times after the merger. We explore early (0.1 s following the merger) and late (1 s) jet launches; the latter is consistent with the time delay of ≈1.74 s observed between GW170817 and GRB 170817A. We demonstrate that the semi-analytical estimates correctly predict the jets’ breakout and collimation conditions. When comparing our synthetic afterglow light curves to the observed radio data of GW170807, we find a good agreement for a 3 × 1049 erg jet launched late with an opening angle in the range ≃5°–7°.
Swift Observations of Mrk 421 in Selected Epochs. IV. Physical Implications of X-Ray Flaring Activity and Features of Relativistic Magnetic Reconnection in 2018 April–2023 December
Authors: Kapanadze B. , Gurchumelia A. , Aller M.
Published: November 2024

We present the spectral and timing results obtained during the intense observations of Mrk 421 by the Swift-based ultraviolet to X-ray instruments during 2018 April–2023 December. The source showed various strengths of X-ray flaring activity, exceeding a level of 3.5 × 10−9 erg cm−2 s−1 during the strongest 0.3–10 keV flares. Our study identifies a number of intraday brightness variability, including 61 instances that occurred within 1 ks exposures that are consistent with the shock-in-jet scenario and accompanied by significant, fast spectral changes. The source exhibited extreme spectral properties with dominance of the log-parabolic distributions of photons with energy and the frequent occurrence of hard photon indices in the 0.3–10 keV and 0.3–300 GeV bands, with the peak of synchrotron spectral energy distribution E
p detected at the energies beyond 29 keV for the first time. The source showed very fast transitions of log-parabolic-to-power-law spectra, most plausibly caused by turbulence-driven relativistic magnetic reconnection. Our spectral results also demonstrate the importance of the first-order Fermi mechanism within the magnetic field of different confinement efficiencies, stochastic acceleration, transitions in the turbulence spectrum, and hadronic cascades. The X-ray, UV, and γ-ray fluxes showed a lognormal variability, which hints at the imprint of accretion disk instabilities on the blazar jet, as well as the possible presence of hadronic cascades. The UV and γ-ray variabilities demonstrated weak correlations with the X-ray flaring activity, which is not consistent with simple synchrotron self-Compton models and requires more complex particle acceleration and emission scenarios.
Heathers (Erica, Ericaceae) of Madagascar: taxonomy, evolution, ecology and uses

Published: November 2024

Madagascar is a regional diversity centre of the plant genus Erica L. (heathers; anjavidy in Malagasy), with 35 species currently recognised. There is no modern taxonomic treatment of the group, and many collections remain unidentified. We review the taxonomic history of Malagasy Erica, built largely on the 1927 revision by Perrier de la Bâthie, who treated them as Philippia. We summarise diagnostic species descriptions and incorporate them into the Erica Identification Aid. There is clearly morphological variation that is poorly reflected in current species concepts and requires further study. Malagasy Erica most likely form a single radiation also encompassing species from the Mascarenes, according to published and new phylogenetic data. However, resolution within the group is poor, and most species remain unsequenced. Literature and specimen records show that Erica is found in all regions of Madagascar except the dry west and southwest, with the highest species richness on the high mountains. Habitats include the high-altitude “ericoid thickets”, shrubland–grassland mosaics in the central highlands and on the eastern coast, and Uapaca bojeri (tapia) savanna. The ecology of individual Erica species is insufficiently known. There may be both wind- and (currently undocumented) insect-pollinated species. Many Erica species are likely to be part of dynamic ecosystems with infrequent fire regimes. The paleorecord indicates a more widespread ericoid shrub vegetation during the last glacial period. Erica is mainly used as fuelwood, but local uses as tools and medicine have also been reported. None of the Malagasy species has had its conservation status assessed, but estimates suggest at least one-fifth of the species may be threatened. Taxonomic revision of the group, coupled with phylogenomics, is an urgent priority. This would also enable better assessments of ecological variation, local uses and conservation priorities.

Published: November 2024

The paper highlights the correlation between COVID-19 and the heightened susceptibility to arrhythmia - a cardiac rhythm disturbance, in hospitalised individuals. The data indicates a significant positive link between the quantity of COVID-19 instances and the number of patients with rhythm pathology. The COVID-19 infection is linked to an increased risk of arrhythmia. The precise ways in which COVID-19 harms the heart tissue and leads to rhythm and conduction disturbances are not completely known and necessitate additional investigation. Moreover, research indicates that a previous SARS-CoV-2 infection may increase the likelihood of rhythm complications.

Sulle orme di Seneca il Vecchio: la Dictio 23 (= 467 V.) di Ennodio
Authors: Raschieri Amedeo Alessandro
Published: November 2024

[it] La Dictio 23 (= 467 V.) di Ennodio presenta un caso singolare nel panorama della tradizione declamatoria antica, poiché la persona loquens è identificabile con una donna che, senza l’ausilio di un intermediario maschile, accusa il figliastro di aver ucciso il padre e si difende dalla calunnia di adulterio. Inoltre, il testo costituisce un’importante testimonianza della diffusione dell’opera di Seneca il Vecchio in età tardoantica, poiché Ennodio sembra aver tratto il tema della Dictio dalla Controuersia VII 5 della raccolta senecana, sebbene non siamo sicuri che la abbia conosciuta nella forma ampia o in quella abbreviata degli Excerpta.
Les conditions et limites d’un droit à l’altération des données personnelles par les personnes concernées
Authors: LEVALLOIS-BARTH Claire , KELLER Jonathan
Published: November 2024

Le droit à l’autodétermination de la personne concernée sur ses données personnelles, consacré par le règlement Général de Protection des Données (RGPD), est de plus en plus questionné dans une société constamment connectée. Contrairement au droit positif en vigueur, le droit à leur altération – objet de la présente contribution – se situerait, quant à lui, a priori du traitement. Dans cette hypothèse, la personne concernée modifierait volontairement la qualité ou la véracité de ses données personnelles pour en dissimuler la véracité. Après avoir défini l’intérêt pratique, puis les fondements juridiques de ce droit, cet article testera ce droit dans divers traitements de données personnelles réalisés soit par des opérateurs privés à des fins contractuelles, ou par des autorités publiques à des fins d’identification ou de surveillance. Enfin, nous examinerons la conformité juridique d’usages ou d’outils pour dissimuler ses données personnelles dans ce type de contextes pour conclure sur les difficultés pratiques de la mise en œuvre de ce droit pourtant nécessaire.
Activisme politique et gouvernance au Niger : nature et formes de la répression numérique
Authors: ALZOUMA Gado
Published: November 2024

Autant l’activisme numérique s’est renforcé ces dernières années sur le continent africain avec l’expansion du téléphone portable et des réseaux sociaux, autant les gouvernements dictatoriaux ou autoritaires ont adapté leurs méthodes de répression à la nouvelle situation. On le voit surtout dans l’usage que ces gouvernements font des technologies de l’information et de la communication (TIC) pour consolider leur pouvoir et/ou exercer une surveillance plus accrue et une répression plus forte sur les citoyens. Dans cet article, nous nous appuierons sur le cas du Niger pour mettre en évidence les multiples formes de répression mises en œuvre par les pouvoirs autoritaires africains en réaction à l’usage croissant des TIC pour élargir l’espace des libertés publiques. Nous nous proposons de démontrer que dans les États autoritaires caractérisés par le dénuement technologique, en particulier un faible accès aux instruments numériques, un faible niveau d’éducation et une faible sophistication de l’appareil d’État, la répression numérique ne se distingue des formes traditionnelles de répression qu’en ce qu’elle vise exclusivement des utilisateurs d’Internet et des réseaux sociaux.

Published: November 2024

Chitosan-Kappa Carrageenan (Chit-KC) hydrogel films have been made using a casting method with different compositions. This research aimed to investigate the effects of different compositions on the chemical, physical, and mechanical characteristics of the Chit-KC hydrogel films. The compositions of the kappa carrageenan in the Chit-KC films were 0%, 16.67%, 33.33%, 50.0%, and 100.0%. The films were characterized using FTIR, SEM, DTA-TGA, and XRD instruments to analyze their functional groups, morphology, thermal properties, and crystallinity. They were also tested for their solubility, swelling, water vapor permeability (WVP), and mechanical characteristics. The results revealed that the addition of kappa-carrageenan induced the formation of a polyelectrolyte complex. The polyelectrolyte complex caused an increase in swelling, crystallinity, and WVP values and a decrease in solubility, tensile strength, elongation, and elasticity. It also caused the formation of film layers and granules on the surface of the hydrogel film. The IR spectra exhibited that the Chit-KC hydrogel films contained O-H, C-H, C=O, S=O, C-O, and C-O-C groups. The DTA-TGA test results revealed that the film began decomposing at around 200°C and re-decomposing at 300°C.

Published: November 2024

In polymer studies, biocomposite now draws attention as an exciting material obtained from combining natural fiber and matrix, which is an environmentally friendly material with biodegradable properties. One of the natural fibers often used in polymer filler is banana stem fiber. This study aims to prepare carbon-coated waste-dried banana fiber. The waste of banana stems was used as raw material for preparing cellulose-rich banana stem fiber. The banana fiber was soaked in an alkaline solvent, 1% NaOH, to remove the lignin content. The dried banana fiber was then coated with activated carbon and graphite by immersion in the carbon dispersion in ethanol with PVA glue binder added. Fourier-transform infrared (FTIR) and X-ray diffraction (XRD) spectra show different profiles on raw and carbon-coated banana fibers, indicating successful carbon coating. The burning test and thermal analysis results show that carbon-coated banana fibers have better thermal properties than raw banana fiber. This suggests that carbon covered on the fiber surface could enhance its thermal property due to intramolecular bonds between fibers and carbon particles. Graphite-coated banana fibers have the longest burning time and are concluded to have the best fire-retardant properties among all samples. The findings confirmed the potential use of carbon-coated banana fiber as filler material for reinforcing conventional composites.
Enhancement of the Reinforcement Effect of Calcium Carbonate or Silica on Natural Rubber Using Lauryl Alcohol
Authors: Surya Indra , Hanafi Ismail
Published: November 2024

Calcium carbonate (CaCO3) and silica are two types of additives for rubber. Through the implementation of a typical semi-efficient (Semi-EV) vulcanisation formulation, those additives were added separately into the compound of natural rubber (NR). The CaCO3 or silica was added as the reinforcing filler and, incorporated into NR at a constant concentration i.e., 30 parts per hundred NR (phr). It was found that the CaCO3 or silica have successfully provided an increase in mechanical properties including a greater tensibility (tensile strength) and abrasion resistance of the compound of NR. However, as hydrophilic fillers, the CaCO3 or silica is hard to disperse homogeneously and hence, lauryl alcohol was used to improve their dispersion degrees. It was combined into the NR compound with varied concentrations such as 1, 3, 5 and 7 phr. Therefore, the effect of lauryl alcohol concentration on the processing and reinforcement properties of CaCO3 or silica-filled NR was investigated. It could be found that lauryl alcohol has increased the rate coefficient of vulcanisation (Rv) of the CaCO3 or silica-filled-NR. The greater the lauryl alcohol concentration; the greater the Rv value, tensile strength, and abrasion resistance. Overall, lauryl alcohol has a successful function as a plasticizing agent which increased the reinforcement effects of the fillers on NR through the increasing of crosslink density of CaCO3-NR or silica-NR especially at the 5 phr of addition.

Introduction: The provision of crash care presents a pressing health concern globally, with community-based initiatives offering a cost-effective approach to interventions. The objective of this study was to elucidate the potential community-based initiatives to enhance post-crash support for victims of road traffic accidents, specifically focusing on the efforts of Sarvodaya: a non-governmental organization in Sri Lanka.Methods: This case study employed a mixed-method approach, incorporating both quantitative and qualitative components. Data collection was done using self-administered questionnaires and Key Informant Interviews. Purposive sampling was done to identify informants (n=37) for the questionnaire survey.Results: While the informants had mixed perceptions of Sarvodaya's present initiatives to support post-crash care, the REACT – Community Life Saver initiative garnered majority for its potential to address the needs of the Road Traffic Accident victims. Community engagement was deemed insufficient, underscoring the need for enhanced awareness programs. Collaboration with existing resources, including Community Lifesaver Programs and the Red Cross, was identified as pivotal. Strategies for community-based interventions, including awareness campaigns, first aid training, improved emergency response systems, and victim advocacy, were prioritized for implementation. Implementation challenges such as resource constraints, behavioural issues of both drivers and pedestrians, communication gaps, and policy-legal concerns were highlighted. Addressing these challenges is crucial for the effective support of Road Traffic Accident (RTA) victims at the community level.Conclusion and recommendations: The study concludes that Sarvodaya has the potential to spearhead community-based initiatives aimed at enhancing post-crash support for road traffic accident victims, pending the effective resolution of identified constraints.

Central line-associated bloodstream infections (CLABSIs) are severe bloodstream infections caused by catheter use and are often associated with a longer hospital stay, increased healthcare costs, and a higher mortality rate. However, catheter-related bloodstream infections can be successfully treated. It is essential that healthcare workers are aware of central line (CL) insertion and maintenance bundles to reduce and prevent the incidence of CLABSI. The objective of this study was to assess the impact of implementing CL care bundles on hospital-wide CLABSI incidence rates. This is a prospective study conducted at the King Faisal Specialist Hospital and Research Center in Saudi Arabia from January 2017 to December 2021. The research period was divided into two phases: the pre-intervention phase (January 1, 2017 to December 31, 2018) and the post-intervention phase (January, 2019 to December 31, 2020). During both phases, outcome variables, including CLABSI rate, were assessed. In the present study, the total number of CLABSIs is 439, of which 266 were in the pre-intervention phase and 173 were in the post-intervention phase. The overall CLABSI rate significantly decreased from 1.6±0.05 in the pre-intervention phase to 0.9±0.05 in the post-intervention phase. This decline in CLABSI was significant (p<0.0001) across all hospital settings, including critical care and non-critical care units. The implementation of care bundles is essential and has been shown to significantly reduce CLABSI rates in nearly all participating units.

The aim of this brief report is to evaluate sodium-glucose cotransporter 2 inhibitors (SGLT2-I) effects on patients with both refractory ascites and type 2 diabetes mellitus (T2D). We consecutively recruited all the diabetic patients with refractory ascites due to decompensated liver cirrhosis admitted between February and May 2023 at the Internal Medicine Unit of the University Hospital of Palermo. Clinical and laboratory data were collected after starting SGLT2-I therapy. SGLT2-I use was associated with a reduction/resolution of ascites and with an improvement in serum albumin and sodium levels and estimated glomerular filtration rate. SGLT2-I might represent a valid therapeutic option in the treatment of patients with refractory ascites and T2D, as already hypothesized by other research groups.

INTRODUCTION: In integrating Spiral Coverage into Cellular Decomposition, which combines structured grid-based techniques with flexible, quick spiral traversal, time efficiency is increased.OBJECTIVES: In the field of robotics and computational geometry, the study proposes a comparative exploration of two prominent path planning methodologies—Boustrophedon Cellular Decomposition and the innovative Spiral Coverage. Boustrophedon coverage has limitations in time efficiency due to its back-and-forth motion pattern, which can lead to lengthier coverage periods, especially in congested areas. Nevertheless, it is useful in some situations. It is critical to address these time-related issues to make Boustrophedon algorithms more useful in practical settings. METHODS: The research centres on achieving comprehensive cell coverage, addressing the complexities arising from confined spaces and intricate geometries. While conventional methods emphasise route optimization between points, the coverage path planning approach seeks optimal paths that maximize coverage and minimize associated costs. This study delves into the theory, practical implementation, and application of Spiral Coverage integrated with established cellular decomposition techniques.RESULTS: Through comparative analysis, it illustrates the advantages of spiral coverage over boustrophedon coverage in diverse robotics and computational applications. The research highlights Spiral Coverage's superiority in terms of path optimization, computational efficiency, and adaptability, proposing a novel perspective into cell decomposition. The methodology integrates the Spiral Coverage concept, transcending traditional techniques reliant on grids or Voronoi diagrams. Rigorous evaluation validates its potential to enhance path planning, exemplifying a substantial advancement in robotics and computational geometry.CONCLUSION: Our findings show that spiral coverage is on an average 45% more efficient than conventional Boustrophedon coverage. This paper set the basis for the future work on how different algorithms can traverse different shapes more efficiently.

Febrile illnesses contribute significantly to morbidity and mortality in sub-Saharan Africa, but the lack of diagnostic facilities and the broad spectrum of pathogens can lead to inadequate clinical management. The timely and reliable identification of the causative pathogens in febrile patients is the basis for the administration of optimal treatment. We aimed to evaluate the performance of a multiplex polymerase chain reaction (PCR) among blood culture-negative patients presenting with febrile diseases in Central Ethiopia. From April 2016 to June 2018, we collected blood samples from adults and children ≥1 year of age admitted with febrile diseases to the Asella Referral and Teaching Hospital, which is located at an altitude of 2,400 m. Total nucleic acids were extracted from frozen plasma samples using a MagNA Pure 96 instrument (Roche, Mannheim, Germany). The multiplex PCR assays were used in combination with LightCycler multiplex DNA master mix (Roche) on a LightCycler 480 instrument (Roche). We used the pathogen-specific assays targeted to Plasmodium spp., Borrelia spp., Rickettsia spp., Leptospira spp., Salmonella spp., and arboviruses. We tested plasma samples of 511 patients and found positive results for Plasmodium spp. (13, 2.5%), Borrelia spp. (12, 2.3%), and Rickettsia species (7, 1.3%); in total, pathogens were detected in 32 of the samples (6.3%). No pathogen was detected by multiplex PCR in 94% of blood culture-negative samples. Even if the pathogens identified by PCR were not necessarily causes of fever, molecular testing using a multiplex PCR can contribute to pathogen diagnosis in a proportion of febrile patients in the highland part of Ethiopia and help to improve the clinical management.

Tuberculosis (TB) is a leading cause of morbidity and mortality and an important contributory factor to chronic lung disease. TB-associated permanent lung damage manifests with varying levels of respiratory disability long after TB has been successfully treated, which is a condition known as post-TB lung disease (PTLD). This study assessed whether lung function impairment associated with PTLD occurs early during TB treatment. Using a cross-sectional design, we enrolled newly diagnosed adult TB patients aged ≥18 years who had received anti-TB medication for ≥2 months from a large treatment center in northern Nigeria. We used spirometry and the Global Lung Initiative 2012 reference equations for African Americans to assess and characterize lung function for enrolled participants (N = 94). The median age (range) of participants was 34 (18–72) years. Approximately 5.3% (n = 5) of participants exhibited features of abnormal lung function, 4.2% (n = 4) showed features of obstructive lung abnormality, and 1.1% (n = 1) showed restrictive lung abnormality. Compared with historical patients recruited ≥6 months after TB treatment in the same center, our participants had significantly lower forced expiratory volume in one second and forced vital capacity values. Our findings suggest an opportunity for early intervention for primary and secondary prevention of PTLD to reduce the impact of severe respiratory impairment.
