Understanding the processes that led Venus to its current state and will drive its future evolution is a major objective of the next generation of orbiters. In this work we analyze the retrieval of the spin vector, the tidal response, and the moment of inertia of Venus with VERITAS, a NASA Discovery-class mission. By simulating a systematic joint analysis of Doppler tracking data and tie points provided by the onboard synthetic aperture radar, we show that VERITAS will provide accuracies (3σ) in the estimates of the tidal Love number k
2 to 4.6 × 10−4, its tidal phase lag to 0.°05, and the moment of inertia factor to 9.8 × 10−4 (0.3% of the expected value). Applying these results to recent models of the Venus interior, we show that VERITAS will provide much-improved constraints on the interior structure of the planet.
Assessing the effects of different land-use/land-cover input datasets on modelling and mapping terrestrial ecosystem services - Case study Terceira Island (Azores, Portugal)
Authors: Sieber Ina M. , Hinsch Malte , Vergílio Marta , Gil Artur , Burkhard Benjamin
Published: November 2021

Modelling ecosystem services (ES) has become a new standard for the quantification and assessment of various ES. Multiple ES model applications are available that spatially estimate ES supply on the basis of land-use/land-cover (LULC) input data. This paper assesses how different input LULC datasets affect the modelling and mapping of ES supply for a case study on Terceira Island, the Azores (Portugal), namely: (1) the EU-wide CORINE LULC, (2) the Azores Region official LULC map (COS.A 2018) and (3) a remote sensing-based LULC and vegetation map of Terceira Island using Sentinel-2 satellite imagery. The InVEST model suite was applied, modelling altogether six ES (Recreation/Visitation, Pollination, Carbon Storage, Nutrient Delivery Ratio, Sediment Delivery Ratio and Seasonal Water Yield). Model outcomes of the three LULC datasets were compared in terms of similarity, performance and applicability for the user. For some InVEST modules, such as Pollination and Recreation, the differences in the LULC datasets had limited influence on the model results. For InVEST modules, based on more complex calculations and processes, such as Nutrient Delivery Ratio, the output ES maps showed a skewed distribution of ES supply. Yet, model results showed significant differences for differences in all modules and all LULCs. Understanding how differences arise between the LULC input datasets and the respective effect on model results is imperative when computing model-based ES maps. The choice for selecting appropriate LULC data should depend on: 1) the research or policy/decision-making question guiding the modelling study, 2) the ecosystems to be mapped, but also on 3) the spatial resolution of the mapping and 4) data availability at the local level. Communication and transparency on model input data are needed, especially if ES maps are used for supporting land use planning and decision-making.
Maximum principle for the optimal harvesting problem of a size-stage-structured population model
Authors: Chen Miaomiao , Yuan Rong
Published: November 2021

The optimal harvesting of biological resources, which is directly relevant to sustainable development, has attracted more attention. In this paper, we first prove the existence and uniqueness of generalized solution of a size-stage-structured population model while the optimal harvesting effort is discontinuous. Next, we demonstrate the existence of the optimal harvesting policy. Further, based on the idea of the Pontryagin's maximum principle of the optimal control problem in ordinary differential equations, we derive the maximum principle describing the optimal control. Finally, the dynamical behavior of the population is simulated by solving the corresponding optimality system numerically with an algorithm based on the method of backward Euler implicit finite-difference approximation. The numerical simulations indicate harvesting activity will reduce the quantity of the population and that increasing harvesting cost will result in less adult harvested. This provides guideline of implementing harvesting tactic to guarantee the persistence of the population.
Stochastic quasi-subgradient method for stochastic quasi-convex feasibility problems
Authors: Li Gang , Li Minghua , Hu Yaohua
Published: November 2021

The feasibility problem is at the core of the modeling of many problems in various disciplines of mathematics and physical sciences, and the quasi-convex function is widely applied in many fields such as economics, finance, and management science. In this paper, we consider the stochastic quasi-convex feasibility problem (SQFP), which is to find a common point of infinitely many sublevel sets of quasi-convex functions. Inspired by the idea of a stochastic index scheme, we propose a stochastic quasi-subgradient method to solve the SQFP, in which the quasi-subgradients of a random (and finite) index set of component quasi-convex functions at the current iterate are used to construct the descent direction at each iteration. Moreover, we introduce a notion of Hölder-type error bound property relative to the random control sequence for the SQFP, and use it to establish the global convergence theorem and convergence rate theory of the stochastic quasi-subgradient method. It is revealed in this paper that the stochastic quasi-subgradient method enjoys both advantages of low computational cost requirement and fast convergence feature.

Nonconvex regularization for blurred images with Cauchy noise
Authors: Ai Xiao , Ni Guoxi , Zeng Tieyong
Published: November 2021

In this paper, we propose a nonconvex regularization model for images damaged by Cauchy noise and blur. This model is based on the method of the total variational proposed by Federica, Dong and Zeng [SIAM J. Imaging Sci.(2015)], where a variational approach for restoring blurred images with Cauchy noise is used. Here we consider the nonconvex regularization, namely a weighted difference of \begin{document}$ l_1 $\end{document}-norm and \begin{document}$ l_2 $\end{document}-norm coupled with wavelet frame, the alternating direction method of multiplier is carried out for this minimization problem, we describe the details of the algorithm and prove its convergence. Numerical experiments are tested by adding different levels of noise and blur, results show that our method can denoise and deblur the image better.
Tracking the critical points of curves evolving under planar curvature flows
Authors: Fehér Eszter , Domokos Gábor , Krauskopf Bernd
Published: November 2021

We are concerned with the evolution of planar, star-like curves and associated shapes under a broad class of curvature-driven geometric flows, which we refer to as the Andrews-Bloore flow. This family of flows has two parameters that control one constant and one curvature-dependent component for the velocity in the direction of the normal to the curve. The Andrews-Bloore flow includes as special cases the well known Eikonal, curve-shortening and affine shortening flows, and for positive parameter values its evolution shrinks the area enclosed by the curve to zero in finite time. A question of key interest has been how various shape descriptors of the evolving shape behave as this limit is approached. Star-like curves (which include convex curves) can be represented by a periodic scalar polar distance function \begin{document}$ r(\varphi) $\end{document} measured from a reference point, which may or may not be fixed. An important question is how the numbers and the trajectories of critical points of the distance function \begin{document}$ r(\varphi) $\end{document} and of the curvature \begin{document}$ \kappa(\varphi) $\end{document} (characterized by \begin{document}$ dr/d\varphi = 0 $\end{document} and \begin{document}$ d\kappa /d\varphi = 0 $\end{document}, respectively) evolve under the Andrews-Bloore flows for different choices of the parameters.

We present a numerical method that is specifically designed to meet the challenge of computing accurate trajectories of the critical points of an evolving curve up to the vicinity of a limiting shape. Each curve is represented by a piecewise polynomial periodic radial distance function, as determined by a chosen mesh; different types of meshes and mesh adaptation can be chosen to ensure a good balance between accuracy and computational cost. As we demonstrate with test-case examples and two longer case studies, our method allows one to perform numerical investigations into subtle questions of planar curve evolution. More specifically — in the spirit of experimental mathematics — we provide illustrations of some known results, numerical evidence for two stated conjectures, as well as new insights and observations regarding the limits of shapes and their critical points.
Improved Lagrangian-PPA based prediction correction method for linearly constrained convex optimization
Authors: You Yanfei , Jiang Suhong
Published: November 2021

This paper presents an improved Lagrangian-PPA based prediction correction method to solve linearly constrained convex optimization problem. At each iteration, the predictor is achieved by minimizing the proximal Lagrangian function with respect to the primal and dual variables. These optimization subproblems involved either admit analytical solutions or can be solved by a fast algorithm. The new update is generated by using the information of the current iterate and the predictor, as well as an appropriately chosen stepsize. Compared with the existing PPA based method, the parameters are relaxed. We also establish the convergence and convergence rate of the proposed method. Finally, numerical experiments are conducted to show the efficiency of our Lagrangian-PPA based prediction correction method.
Project portfolio selection based on multi-project synergy
Authors: Wang Zonghan , Esangbedo Moses Olabhele , Bai Sijun
Published: November 2021

To date, the selection of a project portfolio that maximises the decision-making outcome remains essential. However, existing research on project synergy has mainly focused on two projects, while there are multiple projects in some cases. Two kinds of synergies among multiple projects are proposed. First, multiple projects must be selected together, in order to produce synergy. Second, some projects depend on synergy with other projects, leading to a synergetic increase in performance. Furthermore, we present strategic synergy, with benefits, resources, and technology, which is quantified for a procurement project concerning a COVID-19 pandemic recovery plan. A design structure matrix is used to describe the technology diffusion among the projects. Then, strategic alignment is utilised to measure the strategic contribution of projects. Next, a portfolio selection model considering uncertainty is established, based on the strategic utility. Finally, our results indicate that selecting projects considering multi-project synergy is more advantageous.

Ḥimāya Revisited
Authors: Paul Jürgen
Published: November 2021

In 1956, Claude Cahen’s study “Notes pour l’histoire de la ḥimāya was published in the Mélanges Louis Massignon. Cahen assumed that protection (ḥimāya) was first sought and granted for land holdings (against fiscal claims), and that the institution then evolved to a personal relationship which no longer necessarily involved land holdings. This subject, of eminent importance for understanding protection, protectors and protégés in early (and later) Islamic history, has not gained the attention it certainly deserves.The article takes another look at Cahen’s sources; it tries to extend the source basis. The article shows various uses of the term, in particular the ways ḥimāya appointments were used in the Buyid period to integrate leaders on the nomad periphery into government structures. The article also takes the investigation beyond Cahen’s time frame, into the 12th century: Cahen thought that the term and the institution did not play a great role in that period any longer, but in eastern Iran especially, it was later used for illegal and undesired practices. In a concluding part, I’ll have a look at the use of the term and the institution in the Mongol period.
Le cercle des poètes disparus et comment y entrer. Une lecture de la notice d’Ibrāhīm al‑Ṣūlī dans le Wafayāt al‑aʿyān d’Ibn Ḫallikān
Authors: Hoorelbeke Mathias
Published: November 2021

Les auteurs d’ouvrages biographiques se trouvent fréquemment confrontés à des personnages aux talents multiples. Ces derniers posent des problèmes de classification qui ne sont pas toujours anodins et peuvent influer sur la structuration de la notice. C’est ce phénomène qui est à l’œuvre dans notice d’Ibrāhīm b. al‑ʿAbbās al‑Ṣūlī dans le Wafayāt al‑aʿyān. En choisissant de faire de ce personnage un poète avant tout, Ibn Ḫallikān se démarque de la tradition antérieure. Il s’emploie donc à étayer son choix au moyen de divers procédés littéraires qui entrent en contradiction avec le strict principe de concision qu’il s’est fixé dans son introduction. Cette discrète argumentation offre au lecteur averti un second degré de lecture, qui redouble l’agrément de ce texte.
Le voyage en Occident de Muḥammad Nāǧī (1888-1956). Esquisse d’un nationalisme
Authors: Segone Brenda
Published: November 2021

L’article examine le rôle du voyage en Occident sur l’évolution artistique de Muḥammad Nāǧī (1888‑1956), pionnier de la peinture moderne égyptienne, à travers les quatre périodes temporelles qui ont marqué sa réflexion plastique : l’Antiquité gréco‑romaine, l’Égypte ancienne, l’Europe moderne, et enfin, l’Égypte moderne. L’Alexandrin, francophone, est témoin du processus d’indépendance de son pays. Son exemple nous livre un aperçu des problématiques auxquelles ont été confrontés les artistes au temps de la nahḍa. Il puise, dans le dialogue constant qu’il établit entre l’Égypte et l’Europe, entre le présent et le passé, les racines d’un langage pictural nouveau. Ses déplacements lui permettent de réaliser dans son pays un projet de renaissance artistique de grande envergure. Le voyage en Occident devient paradoxalement dans ce cas l’atelier d’un nationalisme.

Published: November 2021

Food is any material or substance eaten or drunk to provide energy and nutrients for the body's growth, development, and maintenance. Food can be considered safe if it is free from all hazardous substances that can affect consumer health. Food safety issues can place a high burden of responsibility on traders, government bodies, and international organizations. This chapter covers the hazards, their types, foodborne diseases, and strategies to ensure food safety and quality. Different food quality and safety assurance programs are discussed as well like quality management systems, HACCP certification, ISO 9000 family, good manufacturing practices (GMP)/good hygiene practices (GHP), total quality management (TQM), good working practices (GWP), good lab practices (GLP), etc. Moreover, the role of some novel processing technologies is also focused on in this regard.

Published: November 2021

Polystyrene is commonly used on a daily basis for the packaging of takeaways as if people assume that it is safe. Although studies show the migration of styrene into food could cause adverse health impacts such as cancer, neurotoxicity, and hormone-related problems, less is known about public awareness of its risk. This chapter presents a study conducted to assess the level of knowledge, attitude, and practice (KAP) of polystyrene food packaging usage among food operators (i.e., hawkers, restaurants, and night market). Data were collected using self-administered to survey 115 food operators. Results show that the food operators have a moderate knowledge and attitude in polystyrene usage. Their practice in polystyrene usage is still poor. Food operators from restaurants had the highest level of KAP compared to hawker and night markets. The finding could provide some guides in developing interventions to educate food operators about food safety issues related to polystyrene.

Nieznany rysunek herbu Lublina z XVII w. Appendix do artykułu Marii Trojanowskiej Wizerunek herbu miasta Lublina w źródłach archiwalnych z XV–XVIII wieku
Authors: Kus Józef
Published: November 2021

Artykuł dotyczy nieznanego wizerunku herbu Lublina z 1654 r., znajdującego się w lubelskiej księdze miejskiej przechowywanej w Narodowym Archiwum Historycznym Białorusi w Mińsku. Obok odcisków pieczęci wszystkich instytucji prawnych związanych z miastem, rysunki herbu są najcenniejszym materiałem źródłowym, który informuje o najważniejszym elemencie heraldycznym godła Lublina. Pisarzem kancelarii radzieckiej był w tym czasie Szymon Stanisław Kukro i jemu należy przypisać autorstwo rysunku. Kukro objął ten urząd w 1647 r. i pełnił go do 1675 r. Prezentowany wizerunek przedstawia na owalnej tarczy kozła zwróconego w prawo, w pozycji pionowej, wspinającego się z pagórka na krzew winnej latorośli. Ze wszystkich znanych nam rysunków herbu Lublina z okresu staropolskiego „koziołek” Szymona Stanisława Kukro najbardziej zbliżony jest do obecnego, zatwierdzonego w 2004 r. The Unknown Image of the Lublin Coat of Arms of the 17th Century. Appendix to the Article by Maria Trojanowska The Image of the City of Lublin Coat of Arms in the Archival Sources of the 15th–18th Centuries The article concerns the unknown image of the Lublin coat of arms of 1654, which is in the town book kept in the National Historical Archive of Belarus in Minsk. Apart from the imprints of the seals of all legal institutions connected with the city, the images of the coat of arms are the most precious source materials that inform about the most important heraldic element of Lublin’s emblem. At that time, the clerk of the town council chancellery was Szymon Stanisław Kruk and it is to him that the authorship of the drawing should be attributed. Kukro took the office in 1647 and held it until 1675. The presented image depicts a goat turned to the right on an oval-shaped shield. The goat is in a vertical position, climbing from a hill on a grapevine. Out of all known drawings of the Lublin coat of arms from the Old-Polish period, the “goat” of Szymon Stanisław Kukro best resembles the present one, approved in 2004.
Rethinking Sport Tourism Events in a Post-Covid-19 South Africa
Authors: Daniels Tracy , Tichaawa Tembi M
Published: November 2021

Sport tourism and its related events have been identified as a unique niche product and South Africa is considered globally as a leading sport event tourism destination. Despite the devastating impacts of the COVID-19 pandemic on the sector, it is recognised for its resilience and ability to overcome crises thereby creating employment and assisting economies to recover. For this recovery to effectively take place, recovery strategies, frameworks and policies are now a necessity for the sustainability of South Africa as a sport event tourism destination. The purpose of this paper is to provide a critical review of existing published and unpublished literature sources and policy documents in order to identify the impacts of the COVID-19 pandemic on sport event tourism in South Africa and to propose directions for recovery strategies going forward, as well as recommendations for future research areas. In doing so, the current paper has found that through adequate recovery policies, strategies and frameworks, sport event tourism in South Africa can effectively be used as a post pandemic tool for urban regeneration, new business opportunities and a range of positive social impacts for host communities. As the sub sector begins to reopen, recovery strategies that include considerations of risk communication, community engagement, risk mitigation and the hosting of hybrid events are essential for its sustainability. For the effective implementation hereof, additional research is needed in the fields of crises in sport event tourism, the use of technology in the sub sector, as well as collaboration in small scale sport event tourism.

Malice in Wonder-How-This-Happened Land: Falling Down the Political Rabid Hole of Academia
Authors: McDonald Denise
Published: November 2021

Spiritedly inspired by the well-known, nonsensical children’s stories Alice’s Adventures in Wonderland and Through the Looking Glass, this satirical narrative describes common academic experiences within a fictitious frame. Many children’s stories present a foundational basis for the early life lessons of justice, truth, fairness, and how power corrupts. Therefore, regression to a simpler understanding of complex social interactions potentially frees one’s thinking, which frequently becomes muddled in adult-acquired ego, hubris, and sense of status. So, when adults act illogically (or like children), sense can be made of unreasonable juvenile actions by re-storying irrational episodes through the logical lens of adolescent literature and satire; thereby, establishing a safe distance for examining emotional issues and tapping into imagination for making meaning of taxing experiences. This deliberately playful narrative explores how in academia, the projection of privilege and power often generates troublesome challenges that lead down a political rabid hole of unsolvable riddles.

Published: November 2021

Research on gamified language learning often involves the use of digital games. Little is known about the use of non-technology games in promoting language learning despite their accessibility. This paper aims to fill in this lacuna by providing insights into international students’ engagement in non-technology gamified English language learning in the context of a Lithuanian university. The research, which used a case study approach as its methodology, involved a total of 30 international students at a Lithuanian university together with their two instructors. They were observed for two weeks, and then interviewed by the researchers. An inductive thematic analysis approach proposed by Braun and Clark was used to analyse the data. The findings revealed that the students’ engagement with the non-technology gamified lessons have impacted them positively as they believe that they have improved English language proficiency and better mastery of the 21-st century learning skills. However, the participants raised several issues related to cultural sensitivity and blurred learning outcomes. This study concluded that non-technology games serve as a useful tool in promoting language learning in the 21st century if it is carefully designed to attract learners’ interests and at the same to time meet the learning outcomes. This study is hoped to encourage practitioners to experiment with non-technology gamified lessons and provide guidelines for them in conducting effective non-technology gamified lessons.

The article analyzes orthographic tasks that are part of teaching content in Serbian orthography at the elementary school age. These contents, especially at the younger school age, are an essential part of teaching Serbian. The plan and program cover all major orhographic topics, starting with the use of capital letters, through merged and conquered spelling, punctuation, and abbreviations. The orthographic aspect of voice alternatives is given in the older classes, although the basics of these rules are given at a younger age in changing the form of words (in the writing of nouns of the vrabac – vrapca type, mn. vrapci, zadatak, zadatka, zadaci, etc.) in word formation (eg. in the construction of deminitives such as sveska – sveščica, noga – nožica, etc.), and in highlighting exceptions such as the absence of alternation in loudness in the contact of sound consonants d and đ with silent consonants s and š (e.g., predsednik, predškolski, etc.). The aim of this paper is to examine the types and quality of exercises and tasks in Serbian orthography at primary school age. The analysis covers orthography units presented in textbooks and orthography literature and additional material used in teaching practice (task collections, etc.). Also, the orthographic tasks given in the Serbian language tests at different levels of competitions were examined.

This paper deals with establishing and solving of potential problems concerning clarification and efficient learning of conditional sentences in the English language, that are a grammar unit which often seems like an insurmountable obstacle for those whose learning target is language mastery and therefore skillful use of these sentences. Primarily, the process of teachers transferring knowledge to secondary school students is taken into consideration, as these students possess the necessary linguistic knowledge and cognitive scheme as a potential for the effective acquisition of the relevant unit. In their case, therefore, the very learning process can result in skillful use of conditional sentences and their activation through linguistic skills. The accent is not only on the process of conditional sentence forming, but also on potential problems, and overcoming of those from the aspect of methodical principles, primarily deductive learning and cognitive approach, with the aim of indicating the importance of teaching grammar as a skill.

Cassava Starch-Based Composite Reinforced with Coconut Mesocarpfibers: Analysis of Physicochemical Stability
Authors:   Faculty of Environment, Jean LorougnonGuédé University, Ivory Coast, Doumbia Ahmed
Published: November 2021

In one of our previous articles, we developed a cassava starch material reinforced with coconut mesocarpfibers. Its properties have been evaluated. It appears that the behavior of the composite depends on the atmospheric conditions of exposure. The purpose of this work is to do a more in-depth physicochemical stability analysis. To do this, identical samples were exposed in different chemical environments: basic, saline, acidic and distilled water. The mass losses are measured after 75 days of immersion in the different solutions in three cases: films without addition of lime and fibers, film with the presence of lime and without reinforcements, and finally the composite with lime and fibers. We observe that, in all cases, the loss of mass decreases with the addition of lime and fibers. However, in the basic solution, this decrease is greater (53.4%) while it remains acceptable in a saline environment (1.1%). In short, this material can be used for several applications in the field of packaging such as the preservation of dry salty products.

The policy of the Cirebon Regency Government in land procurement with the designation of landfill is a very dilemmatic problem, this is caused by many factors that influence it, for that the formulation of public policies that are built must have an integral-comprehensive-holistic approach because waste management problems can have an impact on the existence of the environment. The solutions offered through local government policies must be balanced with community participation through efforts to build awareness and legal compliance. The importance of environmentally friendly waste management must be able to be pursued by all stakeholders in the region, considering that the waste problem must be resolved not only by normalizing the legal order but also formulating public policies that favor the interests and concerns of the community. The land procurement policy for the landfill is an example of a tug of war.

This article is focused on discussing the importance of strengthening emotional intelligence to achieve more integrated human domains. The discussion is in terms of challenges and resilience of emotional intelligence transformation on the psychological and behavioral impact of youth. Human capital resources among youths are the main thrusts of national development, especially from political, economic, social, and educational aspects. However, the role of youth as agents of change in society would be meaningless if it is a transformation from darkness to brightness, from positive to negative, and from peace to chaos. The important elements that need to be as a knowledgeable youth are not merely intellectual intelligence alone, but also need to have a strong emotional and spiritual intelligence to achieve the positive of emotional, thinking and behavior. Emotional intelligence can be a determining factor in behavior and ideology that is more mature and prosperous among the youth of the country. Therefore, the need to have emotional intelligence is as important as intellectual intelligence to achieve a real balance in life. Positive youth can stand up as a citizen who is full of identity and dare to cope with the competitive world, but also wisely handle whatever challenges. A strong emotional intelligence in the youth can also help transform the country's expectations into reality in the quest for the creation of a first-class human capital.
