Abstract
The globular cluster 47 Tucanae (47 Tuc) is one of the most massive star clusters in the Milky Way and is exceptionally rich in exotic stellar populations. For several decades it has been a favorite target of observers, and yet it is computationally very challenging to model because of its large number of stars (N ≳ 106) and high density. Here we present detailed and self-consistent 47 Tuc models computed with the Cluster Monte Carlo code (CMC). The models include all relevant dynamical interactions coupled to stellar and binary evolution, and reproduce various observations, including the surface brightness and velocity dispersion profiles, pulsar accelerations, and numbers of compact objects. We show that the present properties of 47 Tuc are best reproduced by adopting an initial stellar mass function that is both bottom-heavy and top-light relative to standard assumptions (as in, e.g., Kroupa 2001), and an initial Elson profile (Elson et al. 1987) that is overfilling the cluster’s tidal radius. We include new prescriptions in CMC for the formation of binaries through giant star collisions and tidal captures, and we show that these mechanisms play a crucial role in the formation of neutron star binaries and millisecond pulsars in 47 Tuc; our best-fit model contains ∼50 millisecond pulsars, 70% of which are formed through giant collisions and tidal captures. Our models also suggest that 47 Tuc presently contains up to ∼200 stellar-mass black holes, ∼5 binary black holes, ∼15 low-mass X-ray binaries, and ∼300 cataclysmic variables.
z ∼ 2–9 Galaxies Magnified by the Hubble Frontier Field Clusters. I. Source Selection and Surface Density–Magnification Constraints from >2500 Galaxies

Abstract
We assemble a large comprehensive sample of 2534 z ∼ 2, 3, 4, 5, 6, 7, 8, and 9 galaxies lensed by the six clusters from the Hubble Frontier Fields (HFF) program. Making use of the availability of multiple independent magnification models for each of the HFF clusters and alternatively treating one of the models as the “truth,” we show that the median magnification factors from the v4 parametric models are typically reliable to values of 30–50, and in one case to 100. Using the median magnification factor from the latest v4 models, we estimate the UV luminosities of the 2534 lensed z ∼ 2–9 galaxies, finding sources as faint as −12.4 mag at z ∼ 3 and −12.9 mag at z ∼ 7. We explicitly demonstrate the power of the surface density–magnification relations Σ(z) versus μ in the HFF clusters to constrain both distant galaxy properties and cluster lensing properties. Based on the Σ(z) versus μ relations, we show that the median magnification estimates from existing public models must be reliable predictors of the true magnification μ to μ < 15 (95% confidence). We also use the observed Σ(z) versus μ relations to derive constraints on the evolution of the luminosity function faint-end slope from z ∼ 7 to z ∼ 2, showing that faint-end slope results can be consistent with blank-field studies if, and only if, the selection efficiency shows no strong dependence on the magnification factor μ. This can only be the case if very low-luminosity galaxies are very small, being unresolved in deep lensing probes.
Needs of early-career professionals in STM: Findings from two surveys
Authors: Foley Erin , Moriarty Rachel , Martin Kerys 
Published: May 2022

Background: The Early Career Publishers Committee (ECPC) of the STM Association (the International Association of Scientific, Technical, and Medical Publishers)&rsquo;s Early Career Publishers Committee (ECPC) aims to engage, and provide tools and resources for, early-career publishers (ECPs) and professionals. The committee believes it is important to survey the community regularly to understand the background, needs, and concerns of its members to better achieve the committee&rsquo;s goals.
Objectives: Early-career professionals were surveyed in 2014 and 2020: the first survey was undertaken to get a baseline understanding of the community and to guide the newly formed ECPC whereas the second not only sought to review some aspects of the first survey but also to identify and explore ways to improve engagement and support through new or revised survey questions.
Methods: The two surveys were conducted online through the ECPC mailing list and social networks. The surveys were voluntary, with the option to skip some questions, and responses &ndash; some in the form of a rating scale &ndash; were collected anonymously. Each survey remained open for over a month to maximize responses, but neither was pretested. Some questions in the first survey were revised in the second in the light of learnings from the first survey.
Results: Most of respondents were women, 25&ndash;54 years old, from the UK or the US, with higher degrees, and working in editorial roles. In the second survey, many respondents were interested in developing their career either in their current
role or in a different one, and nearly half were actively seeking a new role. Over half said that finding the right role was a challenge. Many had never participated in a publishing-related mentoring scheme, and most had not heard of the STM mentoring scheme before.
Conclusions: More tools, resources, and outreach for entry-level and younger industry members, for those from countries outside the UK and US, and for those seeking to develop their careers may be useful in the future. The mentoring scheme could be publicized more prominently to drive engagement. A new survey will be needed in the next 2&ndash;3 years, given the potential impact of the COVID-19 global pandemic on the number of respondents in the second (2020) survey and their motivation.
Contribution des actes de la pratique à l’histoire du lignage chevaleresque d’Évrecy au Moyen Âge central (XI e -XIII e siècle)
Authors: Trân-Duc Lucile 
Published: May 2022

Si Évrecy a retenu l’attention des historiens médiévistes jusqu’ici, c’est essentiellement pour le haut Moyen Âge. La période suivante n’a fait l’objet que de peu d’études. Pourtant, les actes de la pratique conservés aux Archives départementales du Calvados apportent de précieuses informations sur les xi e - xiii e siècles. C’est ainsi qu’après avoir rappelé la position d’Évrecy au sein du duché de Normandie, entre évêques de Bayeux et comtes de Gloucester, le présent article s’intéresse à l’émergence progressive d’un lignage dit d’Évrecy à compter du xi e siècle. Il s’agit plus particulièrement d’envisager le parcours des membres de cette topolignée en termes de mobilité sociale et d’étudier les stratégies mises en œuvre pour affirmer leur conscience élitaire et leur appartenance à l’aristocratie.

The study examined the awareness level of poultry farmers on biosafety practices on infectious diseases in Kano state, Nigeria. A two-stage sampling procedure was used in selecting 166 respondents through the use of questionnaire. The data were analysed using mean, percentages, and standard deviation. The result showed that the main sources of awareness of biosafety practices were mass media (48.8%), family/friends/neighbours (25.9%) and poultry farmers’ association (PAN) (11.4%). Awareness of biosafety were in the following component cleaning (low pressure washer ( x̄ =1.602) and hand washing after toileting (x̄ =1.789), disinfection covering feeds in the store (x̄ =1.560), manure management (x̄ =1 .608) and removal of dead carcasses (x̄ =1.530). component. At segregation and traffic control all the subcomponents were known except; banning keeping of birds at home (x̄ =1.114), exclusion of rodents & wild birds (x̄ =1.054) and presence of buffer areas around the farm (x̄=1.000). The Majority of the respondents claimed very low levels of awareness of biosafety practices (81.9%), major constraints to biosafety practices among the clienteles were; complexity of the biosecurity, inadequate capital (93.4%) and high cost of the biosafety practices (83.1%). Awareness level of the respondents should be improved upon through sensitization and provision of more extension services in addition to the mass media effort.
The Making of a 21st Century English Language Teacher during the Pandemic
Authors: Chehimi Ghada , Alameddine Mira M. 
Published: May 2022

English language has become a cosmopolitan language. It is the lingua franca of the 21st century. This fact has turned learning the language to a must since it is the international language of communication. As teachers of English for more than 20 years, we have come to realize that to be successful in class, we need to learn and use English as a tool that helps us access information from other cultures and be able to transfer this knowledge and skill to our learners. We also need to provide our learners with enough exposure to English as used in context. However, this is not enough to turn our learners into 21st century citizens of the world. We need to help them become critical thinkers. This has become even harder with the move to online learning due to COVID 19 pandemic. This paper aims at exploring the perceptions of English language instructors in four local Lebanese universities regarding 21st-century critical thinking skills and the instructors' abilities to promote such skills in their classes. Twenty-seven teachers filled a questionnaire, and five participants were interviewed. Descriptive data were analyzed. The data revealed the perceptions and practices of these instructors. The study concludes with recommendations.
The Impact of Modeling and Role Play on Grade Eleven Students’ Achievement and Motivation While Teaching Krebs Cycle in Biology
Authors: Saab Maysa , Shaaban Eman 
Published: May 2022

This study investigated the effect of applying “participant modeling” followed by a role play on grade eleven scientific students’ achievement and motivation in biology. Students usually face problems in understanding difficult biology concepts like Krebs cycle which is composed of a series of biochemical reactions with many molecules and compounds involved. The researcher designed t-shirts with information about the molecules and the reactions of Krebs cycle and students were asked to wear them throughout the teaching/learning process. Implementing participant modeling helped students to memorize the names of the molecules, their role. Then a role play was applied after modeling to relate the chemical reactions together. Nineteen students with ages ranging between 16 and 17 (N=19) enrolled in grade eleven scientific participated in this study. Data was collected using pre and post-achievement tests, and a motivation test that was implemented before and after the intervention. Results showed a significant enhancement in achievement, but no significant change occurred at the level of motivation. Ultimately, recommendations related to both methodology and future researches are offered.
Assessment of the impact of clear-cutting on groundwater regime in swampy habitats

Published: May 2022

The aim of the study was evaluation of clear-cutting effect on water regime in a tree harvesting area. The results were made based on the study carried out in the Rakowski Ditch catchment, in Wielkopolska lowland in Poland. It was found that a more useful method to establish the effects of clear-cutting is to compare the groundwater level (GWL) in the post-clear-cutting area with that in a control area than to analyse the GWL changes in the same area before and after the clear-cutting. Regression analysis is a particularly useful tool in groundwater regime analyses. The results obtained in this study indicated that the groundwater regime changes in the post-clear-cutting area that were manifested as an increase in the mean GWL. The major changes in the groundwater regime after clear-cutting were observed in the minimum levels, while the lowest changes took place in the maximum GWL. The variation in GWL was higher in the period after clear-cutting than in the period before it. The analysis of linear regression of GWL in the well located in the clear-cutting area and that in the control area confirmed the change in the groundwater regime in the post-clear-cutting area. Stronger relations in the period before clear-cutting were observed.

Published: May 2022

In 1996 and 1998, Professor A. Korczyk created a half-sib plantation of the European silver fir (Abies alba Mill.) in the Polish part of the Białowieża Forest (Hajnówka Forest District, sub-district Wilczy Jar, subcompartments 416Ag and 416Сf). The planting was carried out in furrows at a spacing of 1.3 × 1 m in three plots of 0.22 ha each in an area of fresh broadleaved forest. To grow the seedlings, seeds from the “Tisovik” tract (in the Belarusian part of the Białowieża Forest) were used. According to some researchers, the Abies alba in this tract has a natural origin and is a relic of the Białowieża Forest. Given this circumstance, and in connection with the mass drying-out of the Norway spruce, Picea abies (L.) Karst., there is a practical interest in studying the growth of fir establishment in this territory. The results of our studies (2018) indicated the very intensive growth of this species in 22-year-old cultures (sub-compartment 416Ag, plot 1, 10 half-sib families). The trees showed no signs of disease or insect damage, their crowns were conical in shape and the shoots were densely covered with needles. The good state of the forest planting can be considered as evidence of soil and hydrological conditions suitable for growth and meeting the ecological and biological requirements of A. alba, as well as confirmation of its autochthonous nature.

Grounding the Consolationist Concept of Mood in the African Vital Force Theory
Authors: Agada Ada 
Published: May 2022

ABSTRACT
The concept of vital force in African philosophy received its first full articulation in Placide Tempels’s Bantu Philosophy (1959) and has evolved over time from the ontological dimension of a universal actuation and energizing principle to an element of mind, notably in the work of Kwame Gyekye. In this essay, I present the concept of vital force and trace its evolution from the time of its first full articulation by Tempels up to its identification with spirit, or mind, in Gyekye’s thought. I try to defend the thesis that the concept of vital force can ground the notion of mood that takes a pivotal position in the twenty-first century philosophy of consolationism. I adopt an analytical and constructive method in this paper.
Sustainable Development for Uganda: A Switch to Followership Model
Authors: Nakabo Robinah Seruga 
Published: May 2022

ABSTRACT
Leadership, as a habit of thinking, assumes the alpha and omega position for pursuance of sustainable development in Uganda. However, what if we considered followership first? Using literature review, a conceptual framework, and critical reflexivity as data source and analysis, this paper provides a new approach to understand challenges in Uganda. The argument is to transcend leadership models and switch to followership model for possibilities of achieving especially sustainable development. This will not only strengthen democratic practices, but also offers more efficient and effective leadership methods. Followership remains the critical yet silent element that has caused the shift in focus from traits, behavior, and lastly, contingent leadership theories. It is why some leadership theorists are considering feminine styles as more effective because they are prejudiced as natural followers. I suggest possibilities of exploring a followership model where followership is the main factor upon which Empowerment for Sustainable Development (ESD) directly depends.
“Is it possible to do Postmodern Philosophy Unbeknownst?”: On Sophie Oluwole’s and Maulana Karenga’s “Deconstruction” of theIfáLiterary Corpus
Authors: Ofuasia Emmanuel , Sunday Layi Oladipupo 
Published: May 2022

AbstractThis article takes its inspiration from Jacques Derrida to consider how deconstructionism can be done inadvertently. This possibility is underscored when one considers how a very significant phrase in Ifá texts— “A díá fún . . .” has been construed away from its transliteration as “Ifá divination was performed for . . .” by each of Oluwole and Karenga. Oluwole justifies her “deconstruction” on the grounds that such transliteration does not capture the philosophic cogs gravid within Ifá verses. Karenga, through his Kawaida methodology, “improvises” to suit the ethical inferences he seeks to deduce out of the corpus. On this showing, this research infers that each of these scholars have engaged in a reflective activity that passes, on Derrida’s reading, as deconstruction, unbeknownst to them. Would they admit that their intellectual drudgeries amount to postmodern philosophy? This is the primary research question that this disquisition interrogates.

Embora o envelhecimento populacional represente, em certo sentido, uma história de sucesso para a humanidade, ela também representa desafios profundos às instituições públicas que devem se adaptar a uma estrutura etária em constante mudança. O primeiro desafio está associado ao aumento sistemático da população aposentada idosa em relação ao encolhimento da população em idade de trabalho, o que cria pressões sociais e políticas sobre os sistemas de apoio social, o envelhecimento populacional também é um grande desafio para os sistemas de saúde com o crescente aumento dos gastos públicos. Baseado em evidências colhidas na literatura, em dados socioeconômicos e demográficos e com a análise dos dados estatísticos o estudo demonstra a taxa de envelhecimento populacional no âmbito dos 28 COREDEs do estado do Rio Grande do Sul.
