[The Conversation Africa] A number of reports have called South Africa a politically polarised society. This may seem uncontroversial, given the country's history of dispossession and discrimination during colonialism and apartheid, and their continuing legacy after 30 years of democracy.

One of the challenges of our present spiritual situation is that our society has settled for something less than truth. This affects the quality of our opinions, policies, and judgments and undermines our ability to live and spread the Gospel. An indicator of the seriousness of this is our growing inability to listen to, learn from, and love people who think differently than we do. In this presentation, I frame the situation as a problem of discernment, compare scientific and Orthodox methods of knowing, and describe how polarization keeps us from using either well. I conclude with a discussion of the critical role diversity plays in discerning truth, and how the Gospel can transform the (Babelic) divisions that deafen us to the truth into a (Pentecostal) harmony that proclaims and celebrates it. Emulating the academic forum the paper was written for (the 2020 Institute for Studies in Eastern Theology), Dn. Timothy Kelleher then offers his thoughts on the presentation and subject. Enjoy the show!

Jesus Christ said; “Come to me, all who labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn from me; for I am gentle and lowly in heart, and you will find rest for your souls. For my yoke is easy, and my burden is light.” (Matthew 11:28​-30) In this retreat, given for the Ukrainian Orthodox League via Zoom on 2/27/2021, Fr. Anthony describes the way the past year has polarized us and how we and our parishes can heal and become the peacemakers the world needs. A video of the presentation is available at Fr. Anthony Perkins YouTube channel. Enjoy!

Dr. Albert Rossi interviews The Right Reverend Paul, Bishop of Chicago and the Midwest in the Orthodox Church in America, on the present condition of polarization within the Church and the United States.

As this week unfolds, half of America will be furious, or crushed in spirit to say the least. Hundreds of millions of others will be elated, full of joy. Of course, a disinterested smaller segment of the population will yawn their way through the news of the day. Truly a nation divided, far from Jesus’ prayer for unity found in John 17. As news junkies and concerned citizens monitor election results and their given candidate’s victory or defeat, our gaze unfortunately shifts from loving God...

For the first time, a multimodal reconstruction of a magnetic thin-film structure has been found using polarised neutron reflectivity. This has been achieved by implementing the Bayesian approach in combination with error correction based on the maximum likelihood method and instrument function optimization.

Calculations and measurements of polarization-dependent soft X-ray scattering intensity are presented during a magnetic hysteresis cycle. It is confirmed that the dependence of the intensity on the magnetic moment can be linear, quadratic or a combination of both, depending on the polarization of the incident X-ray beam and the direction of the magnetic moment. With a linearly polarized beam, the scattered intensity will have a purely quadratic dependence on the magnetic moment when the magnetic moment is parallel to the scattering plane. However, with the magnetic moment perpendicular to the scattering plane, there is also a linear component. This means that, when measuring the hysteresis with linear polarization during a hysteresis cycle, the intensity will be an even function of the applied field when the change in the magnetic moment (and field) is confined within the scattering plane but becomes more complicated when the magnetic moment is out of the scattering plane. Furthermore, with circular polarization, the dependence of the scattered intensity on the moment is a combination of linear and quadratic. With the moment parallel to the scattering plane, the linear component changes with the helicity of the incident beam. Surprisingly, in stark contrast to absorption studies, even when the magnetic moment is perpendicular to the scattering plane there is still a dependence on the moment with a linear component. This linear component is completely independent of the helicity of the beam, meaning that the hysteresis loops will not be inverted with helicity.

The ability to freely control the polarization of X-rays enables measurement techniques relying on circular or linear dichroism, which have become indispensable tools for characterizing the properties of chiral molecules or magnetic structures. Therefore, the demand for polarization control in X-ray free-electron lasers is increasing to enable polarization-sensitive dynamical studies on ultrafast time scales. The soft X-ray branch Athos of SwissFEL was designed with the aim of providing freely adjustable and arbitrary polarization by building its undulator solely from modules of the novel Apple X type. In this paper, the magnetic model of the linear inclined and circular Apple X polarization schemes are studied. The polarization is characterized by measuring the angular electron emission distributions of helium for various polarizations using cold target recoil ion momentum spectroscopy. The generation of fully linear polarized light of arbitrary angle, as well as elliptical polarizations of varying degree, are demonstrated.

Dynamical refinement is a well established method for refining crystal structures against 3D electron diffraction (ED) data and its benefits have been discussed in the literature [Palatinus, Petříček & Corrêa, (2015). Acta Cryst. A71, 235–244; Palatinus, Corrêa et al. (2015). Acta Cryst. B71, 740–751]. However, until now, dynamical refinements have only been conducted using the independent atom model (IAM). Recent research has shown that a more accurate description can be achieved by applying the transferable aspherical atom model (TAAM), but this has been limited only to kinematical refinements [Gruza et al. (2020). Acta Cryst. A76, 92–109; Jha et al. (2021). J. Appl. Cryst. 54, 1234–1243]. In this study, we combine dynamical refinement with TAAM for the crystal structure of 1-methyl­uracil, using data from precession ED. Our results show that this approach improves the residual Fourier electrostatic potential and refinement figures of merit. Furthermore, it leads to systematic changes in the atomic displacement parameters of all atoms and the positions of hydrogen atoms. We found that the refinement results are sensitive to the parameters used in the TAAM modelling process. Though our results show that TAAM offers superior performance compared with IAM in all cases, they also show that TAAM parameters obtained by periodic DFT calculations on the refined structure are superior to the TAAM parameters from the UBDB/MATTS database. It appears that multipolar parameters transferred from the database may not be sufficiently accurate to provide a satisfactory description of all details of the electrostatic potential probed by the 3D ED experiment.

This study examines various methods for modelling the electron density and, thus, the electrostatic potential of an organometallic complex for use in crystal structure refinement against 3D electron diffraction (ED) data. It focuses on modelling the scattering factors of iron(III), considering the electron density distribution specific for coordination with organic linkers. We refined the structural model of the metal–organic complex, iron(III) acetyl­acetonate (FeAcAc), using both the independent atom model (IAM) and the transferable aspherical atom model (TAAM). TAAM refinement initially employed multipolar parameters from the MATTS databank for acetyl­acetonate, while iron was modelled with a spherical and neutral approach (TAAM ligand). Later, custom-made TAAM scattering factors for Fe—O coordination were derived from DFT calculations [TAAM-ligand-Fe(III)]. Our findings show that, in this compound, the TAAM scattering factor corresponding to Fe3+ has a lower scattering amplitude than the Fe3+ charged scattering factor described by IAM. When using scattering factors corresponding to the oxidation state of iron, IAM inaccurately represents electrostatic potential maps and overestimates the scattering potential of the iron. In addition, TAAM significantly improved the fitting of the model to the data, shown by improved R1 values, goodness-of-fit (GooF) and reduced noise in the Fourier difference map (based on the residual distribution analysis). For 3D ED, R1 values improved from 19.36% (IAM) to 17.44% (TAAM-ligand) and 17.49% (TAAM-ligand-Fe3+), and for single-crystal X-ray diffraction (SCXRD) from 3.82 to 2.03% and 1.98%, respectively. For 3D ED, the most significant R1 reductions occurred in the low-resolution region (8.65–2.00 Å), dropping from 20.19% (IAM) to 14.67% and 14.89% for TAAM-ligand and TAAM-ligand-Fe(III), respectively, with less improvement in high-resolution ranges (2.00–0.85 Å). This indicates that the major enhancements are due to better scattering modelling in low-resolution zones. Furthermore, when using TAAM instead of IAM, there was a noticeable improvement in the shape of the thermal ellipsoids, which more closely resembled those of an SCXRD-refined model. This study demonstrates the applicability of more sophisticated scattering factors to improve the refinement of metal–organic complexes against 3D ED data, suggesting the need for more accurate modelling methods and highlighting the potential of TAAM in examining the charge distribution of large molecular structures using 3D ED.

The U.S. lacks icebreaking capability in the Arctic and Antarctic and should build four polar icebreakers with heavy icebreaking capability to help minimize the life-cycle costs of icebreaker acquisition and operations, says a new congressionally mandated letter report from the National Academies of Sciences, Engineering, and Medicine.

A study, by San Diego Zoo Global conservationists, released this week (Sept. 12, 2016) is shedding new light on how scientists evaluate polar bear diet and weight loss during their fasting season. On average, a polar bear loses up to 30 percent of its total body mass while fasting during the open-water season. Although some scientists previously believed land-based foods could supplement the bears' nutritional needs until the sea ice returns, a new study published in the scientific journal Physiological and Biochemical Zoology has revealed that access to terrestrial food is not sufficient to reduce the rate of body mass loss for fasting polar bears.

Politics has traditionally been a taboo topic to discuss on the job. But as people get more vocal about their views -- on everything from from climate change to racial justice, elections to invasions -- it's increasingly hard to keep debate out of the workplace. And that can lead to conflicts between colleagues. Julia Minson of the Harvard Kennedy School of Government and Francesca Gino of Harvard Business School have studied how political polarization is affecting organizations and have advice on handling the challenges it presents. Together, they wrote the HBR article “Managing A Polarized Workforce: How to Foster Debate and Promote Trust.”

Sociologist Claude Fischer writes: Polarization has been less a matter of Americans becoming extremists—most remain centrists or oblivious to politics—but more that politically engaged Americans have increasingly aligned their views, values, and even their practices, from where they live to … Continue reading →

US domestic polarization and implications for the presidential election 30 September 2024 — 5:00PM TO 6:00PM Anonymous (not verified) 19 September 2024 Online

This webinar explores the rise of polarization amongst the US public and implications for the upcoming election.

Domestic polarization has been on the rise in the US in recent years, with Democrats and Republicans moving further away from the centre on key policy issues. As polarization increases, so too do concerns about the state of US democracy and prospects of political violence surrounding the upcoming presidential election. 

This expert panel discusses key questions including:

• What are the driving forces of the growing political divide in the US?
• How far apart are voters on key election issues, from healthcare to immigration to national security?
• How is partisan polarisation altering the effectiveness of US foreign policy and influencing America’s role in the world?

Synaptic transmission leading to release of neurotransmitters in the nervous system is a fast and highly dynamic process. Previously, protein interaction and phosphorylation have been thought to be the main regulators of synaptic transmission. Here we show that sialylation of N-linked glycosylation is a novel potential modulator of neurotransmitter release mechanisms by investigating depolarization-dependent changes of formerly sialylated N-linked glycopeptides. We suggest that negatively charged sialic acids can be modulated, similarly to phosphorylation, by the action of sialyltransferases and sialidases thereby changing local structure and function of membrane glycoproteins. We characterized site-specific alteration in sialylation on N-linked glycoproteins in isolated rat nerve terminals after brief depolarization using quantitative sialiomics. We identified 1965 formerly sialylated N-linked glycosites in synaptic proteins and found that the abundances of 430 glycosites changed after 5 s depolarization. We observed changes on essential synaptic proteins such as synaptic vesicle proteins, ion channels and transporters, neurotransmitter receptors and cell adhesion molecules. This study is to our knowledge the first to describe ultra-fast site-specific modulation of the sialiome after brief stimulation of a biological system.
