The Role of the Social Environment in the Relationship Between Group-Focused Enmity Towards Social Minorities and Politically Motivated Crime
Authors: Krieg Yvonne 
Published: April 2022

AbstractPolitically motivated crime against a person is characterised by the fact that the victims are interchangeable in the sense that individuals are seen as representatives of their social or ethnic group. The current study examines whether the existence of group-focused enmity (GFE) is linked to the perpetration of discriminatory behaviour, in the form of politically motivated crime, which is considered a classic example of the attitude–behaviour relationship. Although various survey studies show connections between group-focused enmity towards social minorities and discriminatory behavioural intentions, there is less knowledge available on whether attitudes can also be regarded as potential risk factors for actual behaviour. The role of the social environment in this relationship, as well as how the attitudes of the social environment are related to the perpetration of politically motivated crime, regardless of personal group-focused enmity, are further analysed. Using a representative student sample from the year 2018 (N = 2824), results show that anti-immigrant, anti-gay, ableist and anti-homeless attitudes are potential risk factors for the perpetration of politically motivated crime against these social minority groups, even after controlling for various other correlates of politically motivated crime. Group-focused enmity has an even greater effect when the student has a like-minded friendship group. Moreover, if the adolescent’s friendship group (hypothetically) approves of such discriminatory behaviour, the likelihood of acting in a politically violent manner is increased, even for adolescents who do not support group-focused enmity.

Published: April 2022

AbstractThe interfacial microstructure and hardness of cladding plates produced by explosive welding between magnesium alloys having different aluminum concentrations and A6005C aluminum alloy were investigated. Further, measurements of residual stress at the interface of cladding plates were performed. In all cladding plates, the bonding interface had a wavy shape. Adiabatic shear bands were formed at the interface on the magnesium alloy side and deformation twins appeared at the interface due to the impact of explosive welding. Microstructure observation using scanning transmission electron microscope revealed that a thin interlayer was formed at the interface in all cladding plates. The thickness of the interlayer increased with an increase in aluminum concentration in the magnesium alloy, while the thickness was 1 μm or less. In the cross-section of the cladding plate, aluminum alloy showed a relatively higher Vickers hardness value compared with the magnesium alloy, and the hardness value increased when approaching the interface. However, nanoindentation tests revealed no increase in hardness was observed at the interface. Measurements of the residual stress using synchrotron radiation x-rays at the interface of cladding plates revealed a tendency for the occurrence of tensile residual stress on the magnesium alloy side and compressive residual stress on the aluminum alloy side. This might be due to a difference in the coefficient of thermal expansion between the magnesium and aluminum alloys.

Published: April 2022

AbstractThe first records of Calamagrostis purpurea, an apomictic wetland grass species with a Euro-Siberian, predominantly boreal distribution, are reported for the Carpathians. This significantly expands the species’ range in Central Europe eastwards from the known localities in Austria and Czechia. Due to in situ finds and revision of the herbarium vouchers, C. purpurea was discovered in the Western Carpathians in Slovakia (the Nízke Tatry Mts) as well as in the Eastern Carpathians in Ukraine (the Chornohora Mts) and Romania (Dorna Depression, the Harghita, Bodoc Mts, Intorsura Buzaului Depression) at 6 sites in total. All these newly found localities are situated within 870–1570 m a.s.l. The locality in the Nízke Tatry Mts is at the highest elevation, while those in the Romanian Carpathians are the southeasternmost in Central Europe. In the Carpathians, C. purpurea is confined to undisturbed wetland habitats, which implies its relict origin in the region. A distribution map, habitat characteristics, morphological description, and images of the plants from the Carpatians are provided. Carpathian populations tested with flow cytometry are DNA-octoploid (the predominant ploidy level of the species in Europe). Because of the species’ rarity and vulnerability, it is suggested to include C. purpurea in the next editions of the Red Data Books and/or Red Lists of the corresponding countries.
Determination of Rate-Dependent Properties in Cohesive Frictional Materials by Instrumented Indentation

Published: April 2022

AbstractThe extraction of the elastoplastic constitutive behavior from instrumented sharp indentation is still a subject of research. Several approaches have been proposed to solve this problem, mainly based on the use of numerical techniques. This work proposes an inverse analysis approach based on dimensional analysis calibrated with finite element modeling, to extract the elastoplastic properties from instrumented sharp indentation in rate- and pressure-dependent materials, which is the typical behavior that most polymers exhibit. Pressure sensitivity was modeled with a Drucker-Prager yield criterion, while rate dependency was introduced through a power-law dependence on strain rate of the yield stress. A set of master curves is proposed that relate the experimental metrics of instrumented indentation tests with the parameters of the proposed material model. Furthermore, the analysis was experimentally validated by testing several materials, including PMMA, coarse grain copper, and ultrafine grain copper. The predictions of the inverse analysis correlated well with the known material properties.
Friction reduction behavior of oil-infused natural wood

Published: April 2022

AbstractNatural materials tend to exhibit excellent performance in the engineering field because of their structure and special functions. A natural red willow, called natural porous wood material (NPWM), was found, and wear tests were conducted to determine its potential as an oil-impregnated material by utilizing its special porous structure. Fluorination treatment was adopted to improve the NPWM properties for absorbing and storing lubricating oil. The different contributions of soaking and fluorination-soaking treatments on the tribological properties of NPWMs and their respective mechanism of effect were revealed. The results showed that the fluorination-soaking treatment helped absorb and store sufficient lubricating oil in the NPWM porous structure; therefore, more lubricating oil would be squeezed out and function as a tribol-film between contacting surfaces during the friction process, thus ultimately contributing to stable and smooth wear responses even under prolong friction. However, the formation of an oil-in-water emulsion, caused by the buoyancy effect, destroyed the oil films on the worn NPWM surface in a water environment, resulting in higher coefficients of friction (COFs) under water conditions than under dry friction, even after the fluorination-soaking treatment. The knowledge gained herein could not only verify the potential of NPWM as an excellent oil-impregnated material in the engineering field but also provide a new methodology for the design of artificial porous materials with stable and smooth friction processes.
Adhesion at friction and wear
Authors: Markov Dmitry P. 
Published: April 2022

AbstractOur understanding of the surrounding world, from friction to the origin of life, depends on how we imagine the contact interaction of condensed bodies. What are the forces acting in contact with solids? Do they attract (adhesive) or repel (dehesive)? Theory and research at the atomic-molecular level have shown that the force are adhesive, but everyday experiences cast doubt on this conclusion. This article addresses this issue by considering the mistakes made in experimental and theoretical tribology and surface physics. Taking into account the theories of hybridization and dehybridization of electron orbitals and valence bonds, the views on the structure of the surfaces of condensed bodies and the force arising during contact interaction are revised. The influence of van der Waals, hydrogen, covalent, metallic, and ionic bonds on the properties of lubricants is evaluated. The contours of the dehesive-deformation theory of friction and wear are also outlined.
Nanotribological properties and scratch resistance of MoS2 bilayer on a SiO2/Si substrate
Authors: Kim Si-hwan , Ahn Hyo-sok 
Published: April 2022

AbstractThe tribological properties and scratch resistance of MoS2 bilayer deposited on SiO2/Si substrates prepared via chemical vapor deposition are investigated. Friction force microscopy (FFM) is employed to investigate the friction and wear properties of the MoS2 bilayer at the nanoscale by applying a normal load ranging from 200 to 1,000 nN. Scratch resistance is measured using the scratch mode in FFM based on a linearly increasing load from 100 to 1,000 nN. Kelvin probe force microscopy (KPFM) is performed to locally measure the surface potential in the tested surface to qualitatively measure the wear/removal of MoS2 layers and identify critical loads associated with the individual failures of the top and bottom layers. The analysis of the contact potential difference values as well as that of KPFM, friction, and height images show that the wear/removal of the top and bottom layers in the MoS2 bilayer system occurred consecutively. The FFM and KPFM results show that the top MoS2 layer begins to degrade at the end of the low friction stage, followed by the bottom layer, thereby resulting in a transitional friction stage owing to the direct contact between the diamond tip and SiO2 substrate. In the stable third stage, the transfer of lubricious MoS2 debris to the tip apex results in contact between the MoS2-transferred tip and SiO2. Nanoscratch test results show two ranges of critical loads, which correspond to the sequential removal of the top and bottom layers.

ABSTRACT

Introduction
As the global population ages, research on the health of middle-aged and elderly men has intensified.

Aim
To report a paucity of data on the prevalence, etiology, and risk factors associated with lack of vaginal intercourse in middle-aged and elderly Chinese men.

Methods
Between January, 2018, and May, 2020, 6,096 men aged 40-90 years old who reside in mainland China were included in the community-based study. Validated scales related to erectile dysfunction (EHS and IIEF-5) and late-onset hypogonadism (ADAM and AMS), and in-person interview method were used to collect data. Multivariable analysis was performed to examine the risk factors associated with the absence of intercourse.

Outcomes
Prevalence estimate of no current vaginal intercourse and its associations with basic factors and medical comorbidities. Reasons for no current vaginal intercourse.

Results
The prevalence of intercourse absence was 19.8% (95% CI; 18.8–20.8%) in middle-aged and elderly Chinese males, and this proportion was significantly higher in older age groups (8.6%, 11.5%, 24.1%, and 34.2% for men aged 40–49, 50–59, 60–69, and 70–90, respectively; P &lt; .05). Among the men who attributed the lack of intercourse to themselves, 168 (21.4%, 95% CI; 18.7–24.4%) had erectile problems and were apprehensive about erectile failure during intercourse. Strained spousal relationships (35 men, 8.4%, 95% CI; 6.1–11.4%), marital issues (163 men, 39%, 95% CI; 34.4–-43.8%), and poor health of the partner (179 men, 42.8%, 95% CI; 38.2–47.6%) were described as reasons for lack of intercourse with spouses. Same risk factors were also found in the multivariate analysis.

Clinical implications
Modifiable factors that are related to lack of intercourse may be beneficial to Chinese middle-aged and elderly men.

Strength & limitations
The main strength of the study is that it involved real-world settings. The limitations are as follows. Firstly, psychological data, data on sexual frequency and data regarding types of sex other than vaginal intercourse were not recorded. Secondly, this is a cross-sectional study, from which definite or causative conclusions can't be drawn. Thirdly, the spouses of the participants were not included in the study, and hence the data represent the perceptions of males only. Finally, objective data are required.

Conclusion
Modifiable factors related to both the patients and their partners were associated with an increased rate of no intercourse in Chinese middle-aged and elderly men. Guidance for sexual life may benefit men with an absence of intercourse. Future studies are warranted to reexamine our findings.
The Affects of Populism
Authors: TIETJEN RUTH REBECCA 
Published: April 2022

AbstractThe current rise of populism is often associated with affects. However, the exact relationship between populism and affects is unclear. This article addresses the question of what is distinctive about populist (appeals to) affects. It does so against the backdrop of a Laclauian conception of populism as a political logic that appeals to a morally laden frontier between two homogenous groups, ‘the people’ and ‘those in power’, in order to establish a new hegemonic order. I argue that it is distinctive of populism that it breaks with the dominating feeling rules by overtly appealing to affects and reclaiming them for the realm of the political. The article explores three groups of affective phenomena: discontent, anger, and fear; empathetic, sympathetic, group-based, and shared emotions; and collective passions of enthusiasm and love. It shows how an appeal to these affects relates to the political logic of populism itself by contributing to the concretization, collectivization, and unification of affects.
Haste Makes Waste: Why China's New Plea Leniency System is Doomed to Fail
Authors: Li Enshen 
Published: April 2022

AbstractIn 2016, China introduced an ‘Admission of Guilt and Acceptance of Punishment’ system (known as ‘plea leniency’) premised primarily on the ideal of punishing crime efficiently while advancing the protection of human rights. In this article, I challenge this official rationale by critically examining the legitimacy of plea leniency as a rights-based approach to crime. Drawing on procedural justice theory, I use extant research data and online criminal judgments from the courts in Shanghai to unravel manifold mismatches between the plea leniency process and a procedurally just decision-making process that respects individual rights. My contention is that the operational dynamics of plea leniency is weighed heavily towards efficacy with little regard for the fundamental norms of due process and fairness in which the procedural legitimacy of this new form of summary dispositions is grounded. By tying the expedition of criminal proceedings to guilty pleas, plea leniency represents a discursive continuity of China's broader criminal justice culture, and as such, it fails in operating on a more just, respectful, and communicative basis to accommodate defendants’ interests which stand at the core of its operation.
A Foundation for Russia? Memories of World War II for Young Russians
Authors: Krawatzek Félix , Frieß Nina 
Published: April 2022

AbstractHow do young Russians relate to World War II and the violence of the wartime period? This article explores the degree to which societal and elite-driven narratives about history converge in the context of a crucial historical anniversary. We demonstrate that the memory of World War II serves as an integrative historical event for an abstract, temporally transcendent idea of Russia. Our analysis draws on focus groups conducted among young people of different political orientation in June 2019, survey data targeting urban youth, conducted over three consecutive years (2018–2020), and cultural artifacts such as film and literature. There is significant overlap between the views that young people express about victory and commemoration and the prevailing cultural, political, educational, and historical discourses. However, there is significant controversy when it comes to the actual ways in which the current political regime remembers the victory, the role of Stalin, and how to understand violence against the civilian population. The shared historical view that the Putin regime has created therefore remains contested. Disagreement limits the extent to which memory can be a foundation for today’s political Russia as young respondents differentiate between their support for an abstract ideal of Russia and the existing political system.
THE NEW THINGS: PROPERTY RIGHTS IN DIGITAL FILES?
Authors: Michels Johan David , Millard Christopher 
Published: April 2022

AbstractThis paper looks at the property status of digital files, such as electronic documents, under English law. We argue that, while mere information is rightly not considered property, digital files are not mere information. Instead, they are distinct virtual objects that exist at the logical – or software – layer of a computer system. Property law could recognise digital files as a new, third kind of thing, alongside things in possession and in action. Doing so might help resolve disputes over access to digital files, by providing proprietary remedies similar to those available for paper documents.
Existence of solution for a class of activator–inhibitor systems
Authors: Figueiredo Giovany , Montenegro Marcelo 
Published: April 2022

AbstractWe prove the existence of a solution for a class of activator–inhibitor system of type
$- \Delta u +u = f(u) -v$
,
$-\Delta v+ v=u$
in
$\mathbb{R}^{N}$
. The function f is a general nonlinearity which can grow polynomially in dimension
$N\geq 3$
or exponentiallly if
$N=2$
. We are able to treat f when it has critical growth corresponding to the Sobolev space we work with. We transform the system into an equation with a nonlocal term. We find a critical point of the corresponding energy functional defined in the space of functions with norm endowed by a scalar product that takes into account such nonlocal term. For that matter, and due to the lack of compactness, we deal with weak convergent minimizing sequences and sequences of Lagrange multipliers of an action minima problem.
Teacher perspective on music performance anxiety: an exploration of coping strategies used by music teachers
Authors: MacAfee Erin , Comeau Gilles 
Published: April 2022

AbstractThe purpose of this study was to explore music performance anxiety (MPA) from music teachers’ perspectives by identifying and describing common coping strategies teachers use to support students with MPA. A quantitative content analysis of scientific and non-scientific MPA literature identified preparation, open communication, realistic expectations, exposure therapy and deep breathing as the five most common coping strategies mentioned in the literature. Qualitative thematic analyses of existing literature and interview transcripts from five piano teacher participants provided descriptions of the five commonly identified coping strategies. A comparison of literature and interview results suggests a gap between research knowledge of MPA and practical teaching application. While music teachers employ a variety of strategies to help students cope with MPA, they may also benefit from formal MPA training opportunities grounded in research to provide additional resources for effectively managing students with MPA.
Rare combination in an infant patient: trisomy 7p and tetralogy of Fallot

Published: April 2022

AbstractThis case report presents an infant patient with the association of trisomy 7p and tetralogy of Fallot(ToF). Patients diagnosed with trisomy 7p should certainly be scheduled for an echocardiographic exam and be scanned for any CHD that may accompany it. The CHD that most frequently accompany this syndrome include atrial septal defect, ventricular septal defect, and patent ductus arteriosis. Yet, it should be known that ToF may also be present, albeit rarely.
Dietary intake of individuals receiving Supplemental Nutrition Assistance Program and food pantry assistance in North Texas

Published: April 2022

AbstractObjective:Food pantries and the Supplemental Nutrition Assistance Program (SNAP) are widely available resources for individuals facing food insecurity, yet the dietary quality of individuals using both programmes is not well characterised. We describe the dietary intake of individuals in North Texas who use both food pantries and SNAP to identify nutritional gaps and opportunities to improve food assistance programmes.Design:We analysed baseline data from a randomised controlled trial examining food security and dietary intake. At baseline, we administered the validated, 26-item Dietary Screener Questionnaire (DSQ). We calculated descriptive statistics for dietary intake variables and compared with the 2020–2025 Dietary Guidelines for Americans recommended intake values.Setting:Two large food pantries in Dallas County, TX.Participants:Eligible participants were English or Spanish speaking adults receiving SNAP benefits who had used the food pantry within the last 4 months.Results:We analysed baseline DSQ data from 320 participants (mean age 47 years; 90% female; 45% Black or African American; 37% Hispanic or Latino). Despite receiving SNAP benefits and food pantry assistance, most participants did not meet the minimum recommended intake values for fruits (88.4%), vegetables (97.4%), fibre (90·7%), whole grains (99·7%), dairy products (98·4%) and Ca (83·4%). Furthermore, 73·2% of participants exceeded the maximum recommended intake for added sugar. Still, the gap between median daily intake and recommended daily intake could be partially bridged with food obtained through current food assistance programmes.Conclusions:Multilevel, coordinated approaches within both SNAP and food pantry networks are needed to improve diet quality in individuals receiving food assistance.
