Change the Numbers: Equity, Diversity, and Inclusivity in STEM | Imogen Coe | TEDxRyersonU
Authors: Coe Imogen 
Published: January 2023

<p>In her talk, Imogen Coe addresses the lack of female representation in STEM; science, technology, engineering and math. Using humour and real life examples, she encourages women (and their allies) to break barriers, challenge stereotypes and demand their opportunity to contribute to science.</p>
<p>Dr. Imogen Coe has worked extensively as an academic scientist and administrator, challenging stereotypes and breaking barriers for girls and women in her field. Imogen sees the the lack of equity, diversity and inclusivity in STEM at Ryerson University in her role as professor and dean of the faculty of science. Low confidence levels and under-representation of young women in STEM disciplines means that we are losing important skill sets and talent, limiting our ability to solve complex problems such as climate change. Imogen is an advocate for women in STEM and she uses data and evidence to demonstrate unfair practices, while providing suggestions on how to fix the system. As someone who was raised with a strong sense of social justice, Imogen believes in the fundamental right of everyone to contribute and participate in STEM to their full potential. Imogen firmly believes that EDI in STEM is not just a woman’s rights issue, but a human rights issue. </p>

The complex chemistry of diversity and inclusion: a 30-year synthesis
Authors: Impellizzeri Stefania , Coe Imogen 
Published: January 2023

<p>Dr. Margaret-Ann Armour’s career as a research chemist, educator, and advocate spanned more than 40 years. Much of her work took place within a disciplinary culture ignorant of the scholarship supporting organizational change towards inclusive excellence. Her contributions are extensively covered in other articles in this special issue, and her achievements are all the more remarkable given that her colleague, Dr. Gordon Freeman, held gender-biased attitudes that he shared in a peer reviewed article in a national science journal. Three decades later, another Canadian chemist, Dr. Tomáš Hudlický, published a peer reviewed essay in an international chemistry journal that included his views on the negative impacts of diversity initiatives on organic synthesis research. Both articles were retracted, but clearly a faulty and pervasively biased peer review system enabled the distribution of prejudiced opinions that were neither informed by demonstrated expertise, nor supported by data. These two events are reflective of challenges that Dr. Armour faced in her efforts to diversify chemical sciences. We need to build on her critical work to increasing awareness about inclusive excellence in chemistry, as well as educating scientists on what constitutes an informed opinion. Here, we use Freeman and Hudlický incidents as case studies to indicate how pervasive bias can be superficially perceived as scientific scholarship. Furthermore, we use analogies of analytical processes to illustrate how talent gets systemically excluded. Finally, we provide recommendations to chemistry community members for improving outcomes in terms of synthesis of new knowledge, ideas, and solutions, toward leveraging all the available human talent and creating an environment that is both excellent and inclusive.</p>

Organisational best practices towards gender equality in science and medicine
Authors: Coe Imogen , Wiley Ryan , Gail Bekker Linda- 
Published: January 2023

<p> In August 2018, the president of the World Bank noted that “‘Human capital’—the potential of individuals—is going to be the most important long-term investment any country can make for its people's future prosperity and quality of life”. Nevertheless, leaders and practitioners in academic science and medicine continue to be unaware of and poorly educated about the nature, extent, and impact of barriers to full participation of women and minorities in science and medicine around the world. This lack of awareness and education results in failures to fully mobilise the human capital of half the population and limits global technological and medical advancements. The chronic lack of recruitment, promotion, and retention of women in science and medicine is due to systemic, structural, organisational, institutional, cultural, and societal barriers to equity and inclusion. These barriers must be identified and removed through increased awareness of the challenges combined with evidence-based, data-driven approaches leading to measurable targets and outcomes. In this Review, we discuss these issues and highlight actions that could achieve gender equality in science and medicine. We survey approaches and insights that have helped to identify and remove systemic bias and barriers in science and medicine, and propose tools that will help organisational change toward gender equality. We describe tools that include formal legislation and mandated quotas at national or large-scale levels (eg, gender parity), techniques that increase fairness (eg, gender equity) through facilitated organisational cultural change at institutional levels, and professional development of core competencies at individual levels. This Review is not intended to be an extensive analysis of all the literature currently available on achieving gender equality in academic medicine and science, but rather, a reflection on finding multifactorial solutions.</p>

Some Implications of Sweden and Finland Joining NATO
Authors: Gunter Michael 
Published: January 2023

Sweden and Finland’s decision to abandon their longtime, famous neutrality and apply for membership in the North Atlantic Treaty Organization (NATO) indicates that Russian president Vladimir Putin’s invasion of Ukraine has disastrously backfired. These two new NATO members will bring tangible geostrategic benefits to the alliance, not just a token weight. NATO has suddenly gained a new and greater strength and legitimacy. As for the Kurds, they need to understand that NATO’s deal with Turkish president Recep Tayyip Erdogan to approve Sweden and Finland’s NATO membership in return for their cracking down on supposed Kurdish terrorists sheltering within their borders is not as hostile to Kurdish interests as they claim. Sweden and Finland are not likely to extradite Kurds accused of political crimes to Turkey. The Kurds should comprehend their very secondary position in the existential power struggle involving NATO and Russia and not overreact against it. As explained below, this deal with Turkey, like earlier ones, is not likely to be as inimical to Kurdish interests as first meets the eye.
Kurdistan under new attacks
Authors: Saltsman Terry , Gunter Michael 
Published: January 2023

The Turkish November 19, 2022, attack on Rojava dubbed Operation Claw-Sword was reputedly launched in retaliation for the earlier November 13 bomb attack on Istanbul’s sleek shopping district known as Istiklal Street that killed six people and wounded at least 80 more. Although it made no sense for the Kurds to attack Istanbul and thus invite new Turkish wrath, Turkey quickly blamed the PKK and its kin Syrian Democratic Forces/Democratic Union Party/Peoples’ Defense Units (SDF/PYD/YPG) in Rojava for the atrocity despite their quick denial. On November 22, Turkey escalated these air strikes by hitting an SDF/PYD/YPG military base adjacent to the main US military base in northeastern Syria housing some of the approximately 900 remaining few but strategically important troops the United States still maintains in Syria. No U.S. casualties were reported. However, a Pentagon spokesman declared that the Turkish airstrike had “directly threatened” U.S. troops stationed in the area. Thus, there is the danger of disastrous miscalculations that could lead to Turkish clashes with the United States. Although there is no credible evidence about who perpetrated the original bombing in Istanbul, one might speculate that some rogue Turkish intelligence element carried out a false flag operation to win support for Erdogan’s upcoming reelection scheduled for June 18, 2023. The PKK and SDF/PYD/YPG have accused Turkey of having used such attacks as a pretext for invasions in the past. General Mazloum Abdi (aka Mazlum Kobane), the SDF commander, claimed the reputed bomber, Ahlam Al-Bashir, was related to ISIS jihadists via her brothers and past husbands, some of whom were killed in battles against Kurdish forces. Also possible is a reputed rogue PKK element, such as the so-called Kurdistan Falcons/Hawks blamed in the past for similar violent atrocities. A jihadist group might also be responsible. Meanwhile, the midterm elections in the United States paradoxically both strengthened and weakened U.S. president Joseph Biden’s hand in all this.

Comprehensive screening strategy coupled with structure-guided engineering of l-threonine aldolase from Pseudomonas putida for enhanced catalytic efficiency towards l-threo-4-methylsulfonylphenylserine
Authors: Li Lihong , Zhang Rongzhen , Xu Yan , Zhang Wenchi 
Published: January 2023

l-Threonine aldolases (TAs) can catalyze aldol condensation reactions to form β-hydroxy-α-amino acids, but afford unsatisfactory conversion and poor stereoselectivity at the Cβ position. In this study, a directed evolution coupling high-throughput screening method was developed to screen more efficient l-TA mutants based on their aldol condensation activity. A mutant library with over 4000 l-TA mutants from Pseudomonas putida were obtained by random mutagenesis. About 10% of mutants retained activity toward 4-methylsulfonylbenzaldehyde, with five site mutations (A9L, Y13K, H133N, E147D, and Y312E) showing higher activity. Iterative combinatorial mutant A9V/Y13K/Y312R catalyzed l-threo-4-methylsulfonylphenylserine with a 72% conversion and 86% diastereoselectivity, representing 2.3-fold and 5.1-fold improvements relative to the wild-type. Molecular dynamics simulations illustrated that additional hydrogen bonds, water bridge force, hydrophobic interactions, and π-cation interactions were present in the A9V/Y13K/Y312R mutant compared with the wild-type to reshape the substrate-binding pocket, resulting in a higher conversion and Cβ stereoselectivity. This study provides a useful strategy for engineering TAs to resolve the low Cβ stereoselectivity problem and contributes to the industrial application of TAs.

Published: January 2023

BackgroundSepsis-induced myocardial dysfunction (SIMD) has a significant contribution to sepsis-caused death in critically ill patients. In recent years, the number of published articles related to SIMD has increased rapidly. However, there was no literature that systematically analyzed and evaluated these documents. Thus, we aimed to lay a foundation for researchers to quickly understand the research hotspots, evolution processes and development trends in the SIMD field via a bibliometric analysis.MethodsArticles related to SIMD were retrieved and extracted from the Web of Science Core Collection on July 19th, 2022. CiteSpace (version 6.1.R2) and VOSviewer (version 1.6.18) were used for performing visual analysis.ResultsA total of 1,076 articles were included. The number of SIMD-related articles published each year has increased significantly. These publications mainly came from 56 countries, led by China and the USA, and 461 institutions, but without stable and close cooperation. As authors, Li Chuanfu published the most articles, while Rudiger Alain had the most co-citations. Shock was the journal with the most studies, and Critical Care Medicine was the most commonly cited journal. All keywords were grouped into six clusters, some of which represented the current and developing research directions of SIMD as the molecular mechanisms.ConclusionResearch on SIMD is flourishing. It is necessary to strengthen cooperation and exchanges between countries and institutions. The molecular mechanisms of SIMD, especially oxidative stress and regulated cell death, will be critical subjects in the future.
Generation of the Early Cretaceous granitoid in the Dazeshan region, Jiaodong Peninsula: Implications for the crustal reworking in the North China Craton
Authors: Dong Leilei , Yang Zhiming , Bai Xin , Deng Chen 
Published: January 2023

Lower crust-derived granitic rocks provide constraints on the crustal reworking process and consequently give hints on the destruction mechanism of the cratons. The North China Craton (NCC) underwent extensive crustal melting in the Mesozoic. This study investigated granitic intrusions in the Dazeshan region of the Jiaodong Peninsula. Whole-rock major and trace element analyses and zircon U-Pb ages coupled with Hf isotopes were used to reveal the crustal reworking processes. Zircons separated from the quartz porphyry, Linglong granite, rhyolite porphyry, and biotite granite showed weighted mean 206Pb-238U ages of 119.2 ± 1.0 Ma, 140.2 ± 1.0 Ma, 120.6 ± 0.5 Ma, and 119.9 ± 0.7 Ma, respectively. The quartz porphyry, rhyolite porphyry, and biotite granite had high silica contents (SiO2 = 74–77 wt.%) but low MgO, Co, and Ni concentrations. The calculated εHf(t) values for the rhyolite porphyry and the biotite granite ranged from −18.3 to −20.0 and −17.8 to −20.2, respectively. These geochemical features imply ancient crust sources. The quartz porphyry showed distinct primitive mantle-normalized rare earth element (REE) patterns and was characterized by lower ΣREE content and lack of pronounced negative Eu anomalies. Whole-rock and zircon Dy/Yb ratios showed no correlation with whole-rock Rb/Sr ratios and zircon Hf contents, reflecting limited effects of crystal fractionation. The Ba/La ratios were also high (&gt;150), but the Sr/Y and La/Yb ratios were low (Sr/Y &lt; 50; La/Yb &lt; 15). These features likely indicate that the quartz porphyry was generated by water-fluxed melting without differentiation. The rhyolite porphyry and biotite granite shared many geochemical similarities, denoting a unified source. The high La/Yb (&gt;30) but low Sr/Y (&lt;20) ratios and apparent negative Eu anomalies indicated plagioclase fractionation. Decreased zircon Dy/Yb with increasing Hf concentrations reflected noticeable amphibole fractionation. These two suites had fairly low Ba/La ratios. These data together point toward an identical source: dehydration melting of a relatively thickened crust. These melts experienced crystal fractionation after extraction. We propose that the intrusions were generated by the underplating of water-rich mafic magma, which provided both fluid and heat and finally induced two kinds of melting.
Study on deformation control of overlying strata in short-wall coordinated filling mining of thick coal seam under aquifer
Authors: Yao Yinan , Jiang Pengfei , Zhou Nan , Du Erbao 
Published: January 2023

The mining of coal resources and the protection of water resources are often in opposition, and this contradiction is more prominent in the mining of thick coal seams due to the difficulty of controlling the overburden deformation. Based on the mining conditions of thick coal seam under the main aquifer of a coal mine in the water shortage area of Northwest China, this paper puts forward the short-wall coordinated filling mining (SCFM) of thick coal seam. The stress analysis of the overall structure consisting of the top and bottom plates, coal pillars and filler at each stage of the mining process was carried out, the length of the short-walled working face suitable for this coal mine was derived, and the key parameters for the mining of the three pan areas of the mine were designed. The analysis results show that the sensitivity of the maximum tensile stress in the roof to the length of the working face is better than the filling rate in the case of short-walled working face arrangement. When the design coal mine working face length is 40 m and the filling rate is 95%, the overburden fissure development height can be controlled to 58.45 m after the whole area of three pan area is retrieved. It is verified by the downhole injection method that the requirement of non-conducting aquifer is satisfied after using SCFM. The research in this paper is of great significance to achieve safe and efficient recovery of coal resources and water conservation under strongly water-rich rock formations.

Published: January 2023

Introduction: Environmental changes have led to changes in the suitable areas for growing certain medicinal plants, which might lead to changes in cultivation areas and quality of medicinal materials. Polygonatum kingianum is a commonly used medicinal plant and, with its growing demand, the sustainable development of P. kingianum is particularly important.Methods: Therefore, this study comprehensively considered environmental variables, such as climate, soil, and topography, collected 181 valid distribution records, and used the MaxEnt to predict and evaluate the changes and potential distribution of P. kingianum.Results: The results showed that the current high-suitability areas (31,534.60 km2) for this medicinal plant are mainly distributed in the Southern part of Yunnan Province, western part of Guangxi Province, and Southwestern part of southwestern Guizhou Province. Under a future climate change scenario, the area of suitable habitats showed a trend of first expansion and then contraction, but the overall trend still expanded. The medicinal plant’s migration trend to the northwest of Guizhou Province and northeast of Yunnan Province was more clear. At the Chinese scale, temperature and precipitation were the important factors affecting the medicinal plant’s distribution. At the national scale, Bio7, Bio12, Bio17, Bio11, S_USDA_TEX_CLASS, and Elevation were key variables affecting P. kingianum distribution, whose cumulative value of percent contribution was 93.6%. At a more precise scale, precipitation, soil variables, and altitude became the key factors affecting its distribution. Among them, S_USDA_TEX_CLASS has the highest contribution rate.Discussion: Overall, the results of this study provided a reference for the determination of suitable planting areas of P. kingianum in China.
