USNO-B1.0 1421-0485411 is an eclipsing binary system newly discovered in the Yunnan-Hong Kong wide-field photometric survey. Its orbital period is 1.295 days. Based on the V- and R-band photometric data collected at Kunming 1.0 m telescope and spectroscopic data observed at Lijiang 2.4 m telescope, we used the Wilson-Devinney program to determine the physical parameters of the binary system. The results show that the mass and radius are 2.21 M
⊙ and 1.70 R
⊙ for the A0V primary component, and 2.11 M
⊙ and 1.77 R
⊙ for the A4–5V secondary one. The observed light curves show higher shoulders around the secondary eclipse, which can originate from hot spots, circumstellar materials, abnormal albedo of the secondary component, etc. Through analyzing and modeling, a quite large albedo (∼1.89) of the secondary component was considered to be the most possible reason for this phenomenon. The position of the two components on the H-R diagram implies that the binary is in main-sequence stage.

We report 491 new near-infrared spectroscopic measurements of 420 near-Earth objects (NEOs) collected on the NASA InfraRed Telescope Facility as part of the MIT-Hawaii NEO Spectroscopic Survey. These measurements were combined with previously published data from Binzel et al. and bias-corrected to derive the intrinsic compositional distribution of the overall NEO population, as well as of subpopulations coming from various escape routes (ERs) in the asteroid belt and beyond. The resulting distributions reflect well the overall compositional gradient of the asteroid belt, with decreasing fractions of silicate-rich (S- and Q-type) bodies and increasing fractions of carbonaceous (B-, C-, D- and P-type) bodies as a function of increasing ER distance from the Sun. The close compositional match between NEOs and their predicted source populations validates dynamical models used to identify ERs and argues against any strong composition change with size in the asteroid belt between ∼5 km and ∼100 m. A notable exception comes from the overabundance of D-type NEOs from the 5:2J and, to a lesser extend, the 3:1J and ν
6 ERs, hinting at the presence of a large population of small D-type asteroids in the main belt. Alternatively, this excess may indicate preferential spectral evolution from D-type surfaces to C and P types as a consequence of space weathering, or point to the fact that D-type objects fragment more often than other spectral types in the NEO space. No further evidence for the existence of collisional families in the main belt, below the detection limit of current main-belt surveys, was found in this work.
A Case Study of the Induced Magnetosphere Boundary at the Martian Subsolar Region

Published: March 2022

One Martian induced magnetosphere boundary (IMB) crossing at the subsolar region is analyzed here with multiple instruments on board MAVEN. Properties of the magnetic field and particles around the IMB are evaluated. We find different trends of variation in magnetic field components at the two sides of an interface coincident with the previously defined ion composition boundary. This case shows the IMB at the Martian dayside could be divided into three parts: two regions (denoted as R1 and R2), with different field and plasma properties, and an interface between them. Currents found in R1 and R2 are flowing in antiparallel, and the current density in R2 (at lower altitude) is significantly larger than that in R1 (at higher altitude). Results indicate the interaction between Mars and the solar wind could induce strong currents in the IMB, which are with antiparallel current directions and separated by an interface where the ion composition changes. This could be a typical feature that occurred during the interaction between the solar wind and the nonmagnetized planets.
Mira Ceti, Atypical Archetype

Published: March 2022

With the aim of unraveling the complexity of the morphokinematics of the circumstellar envelope (CSE) of Mira Ceti, we review, extend, and in some cases revisit Atacama Large Millimeter/submillimeter Array observations of the emission of the SiO(5–4) and CO(3–2) molecular lines. In addition, we present a detailed analysis of the optically thin 13CO(3–2) emission, which provides several important new results. In agreement with observations at infrared and visible wavelengths, we give evidence for the confinement and probably rotation of a dense gas volume within ∼50 au from the star and for a large SiO line width within ∼15 au. We show that the mass-loss process is episodic and takes the form of clumps having a very low SiO/CO abundance ratio compared with similar oxygen-rich long-period variables, probably a result of depletion on dust grains and photodissociation. We evaluate the mass-loss rate associated with the main clumps and compare it with values obtained from single-dish observations. We argue that the SiO emission observed in the southwestern quadrant is not related to the mechanism of generation of the nascent wind but to a mass ejection that occurred 11 years before the observations. We remark that Mira Ceti is not a good archetype in terms of its wind: models aiming at describing the very complex gas-dust chemistry in action in the CSE of oxygen-rich AGB stars may find it difficult to account for its peculiar features and small variations in the parameters deciding when and where mass loss can proceed significantly.
Preferential Acceleration of Heavy Ions in a Spontaneously Fragmenting Flare Current Sheet
Authors: Kramoliš David , Bárta Miroslav , Varady Michal , Bučík Radoslav
Published: March 2022

We study the ion acceleration in a mesoscale, spontaneously fragmenting flare current sheet (SFCS) characterized by the presence of a plasmoid cascade. The main subject of our investigation is to determine whether and how plasmoid cascades at intermediate scales in a fragmented current sheet of a solar flare can impact the (preferential) acceleration of specific ions. The time evolution of the SFCS is obtained from high-resolution 2.5D MHD simulations. The ion trajectories (in the background fields resulting from the MHD model), energies, and pitch angles are calculated using a relativistic test-particle code based on the half-acceleration–rotation–half-acceleration method. For light ions, the main acceleration effects of electromagnetic fields within the SFCS are analyzed using the guiding center approximation. We identify regions with the most-efficient ion acceleration within the SFCS, the accelerator efficiency, and spectra of the accelerated ions. The influence of the charge-to-mass ratio on ion behavior is also studied and resulting ion abundances are compared with observational data. The main ion acceleration takes place in the regions with a strong polarization term, which is part of the first-order Fermi acceleration. Because the term is mass dependent, heavier ions undergo preferential acceleration. The ion energy spectra, abundance-enhancement factors, and differential fluxes, obtained from the model, exhibit power-law profiles, in agreement with observed solar energetic particle events. Nonetheless, the obtained slopes for the abundance-enhancement factor do not exactly match the observed data. The computed slopes and profiles are not sensitive to changes in the initial plasma temperature.

We present the detection of 1617 new transiting-planet candidates, identified in the Transiting Exoplanet Survey Satellite (TESS) full-frame images observed during the Primary Mission (Sectors 1–26). These candidates were initially detected by the Quick-Look Pipeline (QLP), which extracts full-frame image lightcurves for, and searches all stars brighter than, TESS magnitude T = 13.5 mag in each sector. However, QLP heavily relies on manual inspection for the identification of planet candidates, limiting vetting efforts to planet-hosting stars brighter than T = 10.5 mag and leaving millions of potential transit signals unvetted. We describe an independent vetting pipeline applied to QLP transit search results, incorporating both automated vetting tests and manual inspection to identify promising planet candidates around these fainter stars. The new candidates discovered by this ongoing project will allow TESS to significantly improve the statistical power of demographic studies of giant, close-in exoplanets.
Influencing Health Care in the Legislative Arena
Authors: Abood Sheila
Published: March 2022

Nurses are well aware that today’s health care system is in trouble and in need of change. The experiences of many nurses practicing in the real world of health care are motivating them to take on some form of an advocacy role in order to influence a change in policies, laws, or regulations that govern the larger health care system. This type of advocacy necessitates stepping beyond their own practice setting and into the less familiar world of policy and politics, a world in which many nurses do not feel prepared to operate effectively. Successful policy advocacy depends on having the power, the will, the time, and the energy, along with the political skills needed to ‘play the game’ in the legislative arena. This article describes the role of the nurse as health care policy advocate, identifies the power bases available to nurses as they assume that role, discusses the policy process in the legislative arena, and presents strategies for effective action. A list of selected online resources is included to help readers learn more about shaping and influencing future health policy.
Patients and Nurses: A Powerful Force
Authors: Hakesley-Brown Roswyn , Malone Beverly
Published: March 2022

Quality of care is of paramount importance to both patients and nurses. This article examines how the existing patient/nurse partnership is the result of a variety of clinical, political, and organisational power paradigm shifts over time. The significance of this partnership on the quality of care, particularly in terms of the necessary power base required, is then considered. Next the education, health care systems, and diversity issues found in the UK and the US are compared and contrasted. The conclusion focuses on a transatlantic vision for the future in the consolidation of the patient/nurse transaction for the achievement of negotiated, competent, compassionate care and as a continuing force for quality at policy, strategic, and operational levels.
The National Database of Nursing Quality Indicators® (NDNQI®)
Authors: Montalvo Isis
Published: March 2022

The National Database of Nursing Quality IndicatorsTM (NDNQI®) is the only national nursing database that provides quarterly and annual reporting of structure, process, and outcome indicators to evaluate nursing care at the unit level. Linkages between nurse staffing levels and patient outcomes have already been demonstrated through the use of this database. Currently over 1100 facilities in the United States contribute to this growing database which can now be used to show the economic implications of various levels of nurse staffing. The purpose of this article is to describe the work and accomplishments related to the NDNQI as researchers utilize its nursing-sensitive outcomes measures to demonstrate the value of nurses in promoting quality patient care. After reviewing the history of evaluating nursing care quality, this article will explain the purpose of the NDNQI and describe how the database has been operationalized. Accomplishments and future plans of the NDNQI will also be discussed.
The Relationship of Nursing Workforce Characteristics to Patient Outcomes
Authors: Dunton Nancy , Gajewski Byron , Klaus Susan , Pierson Belinda
Published: March 2022

Three reports from the Institute of Medicine found that errors in hospital care were more common than previously thought; that health care delivery should be reorganized to improve the quality of care; and that, operationally, nurses have a critical role in securing patient safety. Now the contribution of nursing to the reduction of adverse events must be established empirically, so that nursing-sensitive indicators can be incorporated in such health care-improvement strategies as public reporting of hospital quality and performance-based payment systems. This article reviews what is known from previous nursing outcomes research and identifies gaps in the current state of knowledge. It then describes the contribution to research that can be made through the National Database of Nursing Quality Indicators TM (NDNQI®). Next it reports an NDNQI study that found three nursing workforce characteristics to be related significantly to patient outcomes: total nursing hours per patient day, percentage of hours supplied by RNs, and years of experience in nursing, and concludes with a discussion of the implications of these findings for both for nursing administrators and outcomes-based, quality-improvement initiatives.
The Costs and Benefits of Nurse Turnover: A Business Case for Nurse Retention
Authors: Jones Cheryl , Gates Michael
Published: March 2022

Nurse turnover is a recurring problem for health care organizations. Nurse retention focuses on preventing nurse turnover and keeping nurses in an organization’s employment. However, decisions about nurse turnover and retention are often made without the support of full and complete knowledge of their associated costs and benefits. This article identifies common nurse turnover and retention costs and benefits, discusses the use of benefit-cost and cost-effectiveness analysis relevant to nurse turnover and retention, and calls for the construction of a business case for nurse retention. It also provides a foundation for including the costs and benefits of nurse turnover and retention in estimating the economic value of nursing.
Vers une transition énergétique allemande adossée aux énergies renouvelables et au gaz ?
Authors: Lepesant Gilles
Published: March 2022

Par l’ambition de ses objectifs, le renoncement quasi-concomitant au nucléaire et au charbon et les succès enregistrés dans le déploiement des énergies renouvelables, l’Allemagne est devenue un laboratoire de la transition. Un laboratoire plus qu’un modèle car le renouvellement rapide du mix énergétique concerne à ce jour principalement le secteur de l’électricité. Le logement et le transport s’avèrent, eux, plus difficile à décarboner. Parallèlement au déploiement des énergies renouvelables, la consommation de gaz augmente ainsi malgré son impact sur le climat. La nécessité de stabiliser le réseau dans le contexte d’une montée en puissance des sources d’énergie intermittentes (éolien et photovoltaïque) comme les besoins de l’industrie et du secteur résidentiel risquent à terme de soutenir la demande en la matière. Or, les réserves allemandes étant proches de l’épuisement, une consommation accrue de gaz renforcerait la dépendance de l’Allemagne à l’égard des fournisseurs étrangers. Les investissements engagés pour renforcer les capacités de production, les infrastructures telles que Nord Stream 2 et les efforts consentis pour consolider un marché gazier fragmenté sont au final de nature à conférer un rôle important au gaz, associé aux énergies renouvelables, dans la transition énergétique.
L’Allemagne et la politique environnementale et climatique européenne : un engagement constant et multi-situé
Authors: Tulmets Elsa
Published: March 2022

L’Allemagne a joué depuis les années 1970 un rôle essentiel dans la mise sur agenda d’une politique environnementale et climatique au niveau européen. Elle a utilisé les différents formats européens, notamment les rencontres franco-allemandes et les présidences européennes, pour imposer un agenda politique en faveur de cette question. Tout comme la gestion des crises dans la politique étrangère de l’Union européenne (UE), la lutte contre le changement climatique est devenue l’un de ses chevaux de bataille en vue de trouver crédibilité et légitimité au niveau européen et international. Cet article montre comment les gouvernements allemands successifs ont construit une rhétorique forte et d’inspiration éthique sur les questions environnementales et climatiques pour développer des politiques dont les ramifications ont progressivement gagné d’autres secteurs d’activité. Les normes et standards développés ont ainsi inspiré le « Pacte Vert européen » qui promeut aussi leur diffusion au niveau international. Les déclarations franco-allemandes, en Triangle de Weimar et au niveau européen montrent la démultiplication récente de cette rhétorique qui contraste souvent avec des difficultés de mise en œuvre en Allemagne. En effet, en Allemagne, la rhétorique n’est pas toujours suivie d’effets, surtout sur les aspects climatiques.
La politique climatique allemande sous l’angle de la politique extérieure et de sécurité : une solution d’avenir ?
Authors: von Lucke Franziskus , Hardt Judith Nora , Windels Loïc
Published: March 2022

Au plus tard depuis le rapport sur le « risque sécuritaire du changement climatique » publié en 2007 par le Conseil scientifique consultatif du gouvernement fédéral allemand sur les changements environnementaux de la planète (WBGU), rapport qui à l’époque avait fait sensation, le changement climatique n’est plus discuté en premier lieu comme un problème environnemental en Allemagne, mais de plus en plus comme une problématique centrale de la politique extérieure et de sécurité. Dans ce contexte, l’Allemagne a même fait de la sécurité climatique un sujet central de son mandat de deux ans (2019-2020) au Conseil de sécurité des Nations unies. Dans notre article, nous jetons un regard critique sur cette évolution et sur l’impact politique d’une « sécuritarisation » croissante du dérèglement climatique. Nous montrons ainsi que cette transformation d’un problème environnemental en un problème de sécurité a contribué à un accroissement de l’attention portée sur ce sujet et au développement de réponses politiques innovantes, mais qu’elle entraîne également certains problèmes comme celui de négliger les mesures d’atténuation, d’infantiliser les pays du Sud ou de courir le risque d’une militarisation rampante, qui doivent trouver leur place dans l’évaluation normative. Nous plaidons par conséquent pour une réorientation du volet climatique de la politique extérieure et de sécurité allemande vers les concepts de sécurité écologique et de justice climatique.
Le changement climatique comme rupture métabolique ? Une actualisation du modèle marxien
Authors: Haug Timothée
Published: March 2022

Parallèlement au retour de la référence à Marx dans les mouvements contemporains pour le climat, de récentes études « écomarxistes » ont tenté d’appliquer le modèle marxien de la « rupture métabolique » ( metabolic rift ) à l’analyse du bouleversement climatique anthropogène. En restituant rapidement l’origine de ce concept élaboré par Marx pour rendre compte de l’épuisement et de l’érosion des terres agraires en régime capitaliste, cette contribution s’interrogera sur les conditions de possibilité d’une généralisation de ce modèle critique au phénomène écologique global du climat. Si une telle actualisation est possible, c’est dans la mesure où Marx formalise déjà la contradiction écologique entre la production économique et les conditions naturelles comme une contradiction temporelle. Sur cette base, il s’agira alors de repenser le rôle des politiques climatiques comme l’exercice d’une contrainte sociale sur l’économie de marché, permettant d’intégrer les intérêts écologiques à long terme dans la détermination des choix productifs.

Rearing insects for food and feed is a rapidly growing industry, because it provides excellent opportunities for a sustainable approach to animal protein production. Two fly species, the black soldier fly (BSF) and the house fly (HF), naturally live in decaying organic matter (e.g. compost), and can thus be effectively reared on organic rest streams from the food and agricultural industry. The adoption of these insects as mini-livestock on microbially rich substrates, however, requires us to address how we can safeguard insect health under mass-rearing conditions. In this review, we discuss what is known about the innate immunity of insects in general, especially focusing on a comparative approach to current knowledge for the two dipteran species BSF and HF. We also discuss environmental factors that may affect innate immunity in mass-rearing settings, including temperature, insect densities and diet composition. Furthermore, we address the role of the microbiome in insect health and the associations of these fly species with detrimental or beneficial microbes. Finally, we present a perspective on important open scientific questions for optimizing the mass rearing of these insects with respect to their health and welfare.
The mopane worm (Gonimbrasia belina Westwood): a review of its biology, ecology and utilisation in Zimbabwe
Authors: Bara G.T. , Sithole R. , Macheka L.
Published: March 2022

The study was aimed at reviewing literature related to traditional mopane production as well as exploring the potential for diapause termination to allow for continuous year-round production. Larvae of mopane worms (Gonimbrasia belina) are highly nutritious and popular food for many people in Southern Africa. Improved and sustained supplies of mopane worms in urban and rural areas can potentially address food and nutrition security problems of the mopane worm harvesters and producers financially. This also has the added advantage of improving people’s access to high-protein food. However, harvesting ofG. belina larvae takes place during a short period (main harvesting period is from November to December and a smaller second harvest April-May). In addition, the availability ofG. belina is a function of parasitism, time of the year, and amount of rainfall, making the production not only seasonal but also erratic and unreliable. The absence of a regulatory and monitoring policy framework that protectsG. belina from over harvesting and over exploitation is also a major concern. These problems, coupled with the seasonal nature of the production hinders all year round harvesting and supply. Findings from this study reveal that the literature is outdated, scant and highlights the need for more research to be conducted on the species. Furthermore, the findings suggest that mopane worms are a significant source of protein for vulnerable population groups, capable of addressing their nutritional protein and livelihood needs. To this end, the paper highlights opportunities for further research and the optimisation of production processes.
On three-dimensional free surface water flows with constant vorticity
Authors: Martin Calin I.
Published: March 2022

We present a survey of recent results on gravity water flows satisfying the three-dimensional water wave problem with constant (non-vanishing) vorticity vector. The main focus is to show that a gravity water flow with constant non-vanishing vorticity has a two-dimensional character in spite of satisfying the three-dimensional water wave equations. More precisely, the flow does not change in one of the two horizontal directions. Passing to a rotating frame, and introducing thus geophysical effects (in the form of Coriolis acceleration) into the governing equations, the two-dimensional character of the flow remains in place. However, the two-dimensionality of the flow manifests now in a horizontal plane. Adding also centripetal terms into the equations further simplifies the flow (under the assumption of constant vorticity vector): the velocity field vanishes, but, however, the pressure function is a quadratic polynomial in the horizontal and vertical variables, and, surprisingly, the surface is non-flat.
Compactness and blow up results for doubly perturbed Yamabe problems on manifolds with non umbilic boundary
Authors: Ghimenti Marco G. , Micheletti Anna Maria
Published: March 2022

We study the stability of compactness of solutions for the Yamabe boundary problem on a compact Riemannian manifold with non umbilic boundary. We prove that the set of solutions of Yamabe boundary problem is a compact set when perturbing the mean curvature of the boundary from below and the scalar curvature with a function whose maximum is not too positive. In addition, we prove the counterpart of the stability result: there exists a blowing up sequence of solutions when we perturb the mean curvature from above or the mean curvature from below and the scalar curvature with a function with a large positive maximum.

In a low-carbon supply chain (LCSC) constructed by a single manufacturer and a single retailer, three decision-making models are established by introducing channel preference attributes. That is, a single sales channel model, an online and offline dual channel model, and a dual channel model in which the manufacturer share revenue with her retailer. Using the mean variance (MV) method to characterize the risk aversion utility function of the manufacturer and the retailer, the following r are found. i) Consumers' preference for low-carbon products is conducive to raising the price of low-carbon products and the firms' profits. ii) The deepening of the retailer's risk aversion promotes the increase of the manufacturer's price, while the impact of the manufacturer's risk aversion has an opposite effects. Although the arbitrage behavior of the retailer can not be completely avoided in the risk aversion environment. However in a limited risk aversion environment, dual-channel development is conducive to increasing the profits of the manufacturer, but may harm the interests of the retailer. iii) Consumers' preference for online channel helps the manufacturer increase prices and profit. iv) The sharing of revenue by the manufacturer to the retailer is conducive to increasing the revenue of the retailer. Based on this, in order to improve corporate profits and promote long-term transactions, the manufacturer can carry out low-carbon promotion and implement a dual-channel strategy. The retailer can actively seek channel cooperation with the manufacturer.
Reimagining queer female histories through fandom
Authors: Turner-Kilburn Ellie Jane
Published: March 2022

Carol (2015), a film directed by Todd Haynes that is set in the 1950s, has quickly become a cult classic among queer audiences and has garnered industry prestige. By accepting the vision of queer female pasts that they have been presented with, fans of Carol use fandom to further shape this history, ensuring that at its core are ideas and practices that center queer connection, sensuality, and visibility. By using this vision of the past, fans not only create a community in the present but also, through this collective reconstruction, connect with lesbian history.
Femslash fandom and the cultivation of white queer genealogies: Longing for histories, reading for futures
Authors: Coccia Emily
Published: March 2022

The recent surge in fan activity around historical figures like Emily Dickinson and Anne Lister reveals an ongoing desire for and investment in cultivating queer histories as a way of addressing the harms of erasure. This popular recovery project, however, reproduces existing hierarchies insofar as it most commonly makes wealthy, white histories legible, leaving others unclaimed and unrecognized. Despite these current tendencies, I offer "too close reading" as a fan-inflected scholarly methodology that holds the possibility of helping readers better recognize less overt forms of queerness across media and in the archives.

Educational Data Mining for Student Performance Prediction: A Systematic Literature Review (2015-2021)
Authors: Bin Roslan Muhammad Haziq , Chen Chwen Jen
Published: March 2022

This systematic literature review aims to identify the recent research trend, most studied factors, and methods used to predict student academic performance from 2015 to 2021. The PRISMA framework guides the study. The study reviews 58 out of 219 research articles from Lens and Scopus databases. The findings indicate that the research focus of current studies revolves around identifying factors influencing student performance, data mining (DM) algorithms performance, and DM related to e-Learning systems. It also reveals that student academic records and demographics are primary aspects that affect student performance. The most used DM approach is classification and the Decision Tree classifier is the most employed DM algorithm.
Digital-Based Interventions for Learners With Mathematics Learning Difficulties
Authors: Wachira Patrick W. , Liu Xiongyi
Published: March 2022

Mathematics proficiency is considered a gateway to success in future mathematics and in the real world. However, difficulty with mathematics learning is common for both general and special needs learners. Students with disabilities especially, are not performing sufficiently to be able to succeed in the real world. The poor performance means that interventions are critically needed to support all students, especially those with disabilities to acquire the knowledge and skills that will enable them to be solve mathematics problems that they encounter in their daily life. An effective approach to support these students is through technology-based interventions. With assistive technology more widely available, a variety of technologies now exist to enhance students' mathematical achievement in all mathematics competencies. This chapter provides a review of research on digital-based mathematics interventions for students with disabilities.
Knowledge as a Public Good in the Internet Age
Authors: Akbaş Akdoğan Dilek
Published: March 2022

As a global public good, knowledge has substantial economic and social value for both developed and developing countries. In a global world, knowledge is evaluated on a global public good within a classification made according to the area in which its externalities spread. In creation and diffusion of global public goods, both governments and international communities have roles, and international governance including voluntary, collaborative actions is required. In this study, crowdfunding is evaluated as a new alternative model for financing public goods. The use of crowdfunding method, especially in the financing of global public goods, may contribute to policy success by increasing policy effectiveness, with the potential to involve all actors in the economy, even individuals.
To Politicize or Not to Politicize
Authors: van Loon Aukje
Published: March 2022

Examining selective politicization across the TTIP and JEEPA negotiations, as well as across the UK and German trade positions, the societal approach to governmental preference formation is applied to test the hypothesis that when an EU trade agreement negotiation affects various domestic stakeholders (interest groups, trade unions, NGOs, and voters) and these form coalitions, either reinforcing or competing with each other's demands, politicization is likely to dominate government preference formation processes, while on the other hand, when coalition-building between domestic stakeholders is largely absent and demands do not conflict, then politicization is unlikely to shape governments' trade positions.
PPGIS Potential in Local Governance and Spatial Planning
Authors: Bąkowska-Waldmann Edyta , Kaczmarek Tomasz
Published: March 2022

A growing interest in participatory planning practices in local governments in Poland resulted in the development of new methods supporting citizens' engagement in decision-making processes. The latest solutions in the public participation methods catalog are based on geoweb tools. One of such tools is the geo-questionnaire developed within the project: Geoportal supporting public participation in spatial planning (GEOPLAN) – an R&D project conducted by the interdisciplinary team of researchers from Adam Mickiewicz University in Poznań supported by IT specialists and urban planning practitioners. The chapter presents the features of PPGIS tools, the development of PPGIS in Poland, the evaluation of the pilot implementations of geo-questionnaires in decision-making processes, and the future of PPGIS in the light of new post-pandemic reality.

Aiming at urban improvements as well as land regularization and community development, these plans have been, however, criticized for being too technical, time consuming, expensive, and top-down oriented, lacking sufficient participation to achieve community consensus on priorities, under severe budget restrictions in complex and fast changing realities. This chapter discusses the results of recent experiences in Belo Horizonte, Brazil using Geodesign framework and geovisualization strategies for collaborative planning in two illegal settlements: Maria Tereza (2016) and the Dandara (2018). A methodology for regularization plans was developed, and improvements to the Geodesign interface were tested with the use of open source Web Maps. Both experiences brought evidence on how the use of the proposed framework may enhance citizens' participation and improve planning methods based on social and community values.

The escalating intensity and duration of heat and flood events in cities increase the importance of green infrastructure design that responds to climate change challenges. The aim of this chapter is to demonstrate the potential of a rapid precinct scaled design approach for street tree planting choices that enables simultaneous assessment of visual impact and environmental performance factors including shade quantification and flood responsiveness. This chapter describes a street tree design decision support system (DDSS) drawing from advances in computational botany, entertainment industries, light engineering, and hydrology modelling. The DDSS is tested at both street and precinct scale using two case studies with results demonstrating the feasibility of rapid scenario assessment of tree placement and species selection. The DDSS allows the streetscape street tree design process to integrate the consideration of changing climatic challenges alongside community aesthetic preferences and provides an extensible framework for designing more resilient and comfortable urban spaces.

The dye-sensitized solar cell is one of the most promising solar cells as an alternative to conventional silicon-based solar cells. The advantages of DSSC compared to conventional silicon-based solar cells are the easy fabrication process and low cost. In general, DSSC consists of semiconductor materials and dye as a photoanode, a catalyst at the counter electrode, and an electrolyte. The problem is that the DSSC performance is not optimal in the light utilization process. One of the ways to improve DSSC performance is by increasing photon absorption. A method that can increase photon absorption on DSSC is by adding a light scattering layer (LSL) using TiO2 microparticles. The technique used in this study for the optical model is the scattering theory and numerical methods using the Finite Differential Time Domain (FDTD). The scattering intensity and incident photon intensity are used for the electron generation process. The result of electron generation is used to model electrically to obtain the value of the short circuit current density and the open-circuit voltage with the diffusion differential equation. DSSC with LSL has higher efficiency than DSSC without LSL. The results obtained from this study DSSC with LSL has an efficiency of 5.5%, Jsc 16 mA/cm2, and an open-circuit voltage of 0.6184 volts. DSSC without LSL has an efficiency of 4.9%, Jsc of 14.5 mA/cm2, and an open-circuit voltage of 0.6073 Volt.

Nanotechnology is receiving an intense attention these days due to its potential application in various fields including cosmeceutical and pharmaceutical. Nanoparticles encapsulating natural extract are usually characterised for their particle size and polydispersity index but zeta potential is hardly discussed. The zeta potential is the measurement that shows the aggregation behaviour, reactivity and toxicology. In this study, nanoparticle encapsulating Cymbopogon sp. have been formulated to develop a cosmeceutical product. The antioxidant properties from aqueous extract of Cymbopogon sp. was encapsulated with chitosan/alginate biopolymeric nanoparticles. Central Composite Design (CCD) of Response Surface Methodology (RSM) was employed to investigate and optimise the effects of independent variables such as pH of SA, concentration of non-ionic surfactant concentration of CaCl2 and pH of chitosan on zeta potential and encapsulation efficiency (EE). Following the model, the optimum condition for zeta potential was selected as 6.2 of sodium alginate pH, 0.12% of non-ionic surfactant concentration, 0.05 concentration of CaCl2 and 5.6 of chitosan pH with negative zeta potential of 18.3mV. The zeta potential obtained experimentally was close to its predicted value which is-18.09mV. The model provides a basis on the optimisation of the zeta potential on chitosan/alginate nanoparticle encapsulating Cymbopogon sp. extracts.

Recent years have seen renewed interest in the application of ionic liquids (ILs) on extraction. Along with this grow of ionic liquids, there are significant concern over the effect of ILs on the biomass extraction. Therefore the aim of this present work was to study the inhibitory effect of synthesized ILs particularly imidazolium hydrogen sulphate [IM][HSO4] and morpholinium tetrafluoroborate [MOR][BF4]. Antibaterial and antifungal activities were carried out againts Bacillus cereus, Bacillus thuringiensis and Pseudallescheria boydii which are the main producer of ferulic acid (FA). Results showed that the inhibitory effects of [IM][HSO4] againts bacteria (Bacillus cereus andBacillus thuringiensis) and fungus (Pseudallescheria boydii) were more extensive with inhibition zone of 20.3 and 52.3 mm respectively compared to [MOR][BF4] with 8.3 and 34.0 mm. This result represented the inhibitory effect of ILs especially on fungus as compared to bacteria tested in this present study.
Residential radon exposure and cancer

Radon is an established human lung carcinogen naturally released as an odorless, colorless gas from soil and rocks. It is a major environmental source of ionizing radiation and can cause oxidative damage to DNA, increasing the risk of cancer. Although the association between radon and lung cancer is well established, the association between radon and other cancers is not.

Based on reported studies, there is no consistent evidence indicating an association between radon and non-lung cancers, but limited literature, heterogenous study design, and confounding variables preclude definitive conclusions.  More research is needed to evaluate the association between residential radon and non-lung cancers, particularly with regard to skin cancer, CNS cancer, and stomach cancer, in which existing literature suggests potential associations with residential radon may exist. However, the literature largely demonstrates that lung cancer is the primary concern associated with residential radon exposure and that non-lung cancers are secondary concerns. These results should be considered in residential radon mitigation efforts.
Exploring strategies for management of disasters associated with illegal gold mining in abandoned mines: A case study of Ekurhuleni Metropolitan Municipality
Authors: Matshusa Khodani , Leonard Llewellyn
Published: March 2022

Due to many abandoned mines that are not rehabilitated, there will be illegal mining. Although the mining industry and government continue to prevent illegal gold mining in abandoned mines by sealing open shafts, it is not possible to close all the shafts at once due to limited resources. Furthermore, after sealing the shafts, illegal miners often create alternative openings to enter underground workings while little or nothing is being done to stop the surface illegal gold mining. As long as illegal gold mining is there, disasters associated with illegal mining are prevalent. Effective disaster preparedness and response requires a competent strategy. The purpose of this study was to develop a strategy that can be used for emergency preparation and rescue efforts associated with disasters caused by abandoned mines and illegal gold mining. In this qualitative study, semi-structured interviews were held with officials and experts on disaster management from the Council for Geoscience and the City of Ekurhuleni. This study indicates that the safety of illegal miners and communities near abandoned mines depends on several factors including the ability to identify and respond to a disaster. The study identified three interlinked themes within the report as strategies for dealing with disasters related to abandoned mines and illegal gold mining. These themes included emergency countermeasures and short-term measures, roles and responsibilities and communication. These interlinked themes should be validated through further research that involves input from the national disaster response community at large. This study will serve as a model that can be implemented in other areas impacted by illegal mining in South Africa.
