Noun2Verb: Probabilistic Frame Semantics for Word Class Conversion
Authors: Yu Lei , Xu Yang
Published: June 2022

Humans can flexibly extend word usages across different grammatical classes, a phenomenon known as word class conversion. Noun-to-verb conversion, or denominal verb (e.g., to Google a cheap flight), is one of the most prevalent forms of word class conversion. However, existing natural language processing systems are impoverished in interpreting and generating novel denominal verb usages. Previous work has suggested that novel denominal verb usages are comprehensible if the listener can compute the intended meaning based on shared knowledge with the speaker. Here we explore a computational formalism for this proposal couched in frame semantics. We present a formal framework, Noun2Verb, that simulates the production and comprehension of novel denominal verb usages by modeling shared knowledge of speaker and listener in semantic frames. We evaluate an incremental set of probabilistic models that learn to interpret and generate novel denominal verb usages via paraphrasing. We show that a model where the speaker and listener cooperatively learn the joint distribution over semantic frame elements better explains the empirical denominal verb usages than state-of-the-art language models, evaluated against data from (1) contemporary English in both adult and child speech, (2) contemporary Mandarin Chinese, and (3) the historical development of English. Our work grounds word class conversion in probabilistic frame semantics and bridges the gap between natural language processing systems and humans in lexical creativity.

A new species of the genus Sweltsa Ricker, 1943, Sweltsa lateoblonga Rehman, Du & Huo sp. nov. from Wanglang Nature Reserve, Sichuan Province, China, is described and compared with similar species. A new species group, Sweltsa recurvata group, is proposed for Sweltsa species that lack a transverse ridge on tergum 9. The new species, together with five recognized Palearctic and two Nearctic species, are included in the new group. A taxonomic key to species in this group is included. In addition, unidentified male and female specimens of Sweltsa recorded from Anzihe Nature Reserve, Sichuan Province, and its morphological differences with similar species are discussed with contemporary color images.
Low-noise delta-sigma analog front end with capacitor swapping technique for capacitive microsensors
Authors: Nam Kyeongsik , Kim Hyungseup , Choi Gyuri , Yoo Mookyoung , Ko Hyoungho
Published: June 2022

In this paper, low-noise incremental delta–sigma analog front end (AFE) integrated circuit (IC) for capacitive microsensors is presented. A conventional capacitance-to-digital converter (CDC) mainly uses a multi-stage capacitive sensing amplified stage (CSA) and analog-to-digital converters. The multi-stage CSA is not suitable for application in various Internet of things (IoT) devices that require low power because the power consumption of the analog front-end circuit increases in proportion to the number of amplifiers and the chip area increases. So, the presented delta-sigma AFE can convert the capacitance changes to the digital codes directly. This structure can achieve a small active area and low power consumption. The delta–sigma AFE achieves low-noise and high linearity using a capacitor polarity swapping technique. The measured effective resolution is 16.2 bits, and the non-linearity is 0.05% full-scale output (FSO). The integrated circuit is implemented in a 0.18-µm standard CMOS process. All functional blocks, including the analog circuits (bandgap reference, voltage reference, and delta–sigma capacitance-to-digital converter) and digital block (accumulator and timing generator), are integrated on a chip. The proposed incremental delta–sigma AFE consumes 1.12 mW of power from a 3.3-V supply at a sampling frequency of 500 kHz and occupies a total active area of 0.42 mm2.
High strength, tough/damping and creep resistant EVA/HNT nanocomposites via help of EVA-g-MA compatibilizer
Authors: Tekay Emre , Şen Sinan
Published: June 2022

Organophilic halloysite nanotube (Org-HNT) reinforced poly (ethylene-co-vinyl acetate) (EVA) nanocomposites were obtained with melt compounding technique with use of 10 wt% EVA-g-MA and Org-HNT. The use of EVA-g-MA in the nanocomposites provided a better distribution of the nanotubes as evidenced by the Scanning Electron Microscope (SEM) images. This is due to MA moiety of the EVA-g-MA interacting with the Org-HNT, which decreased its intertubular interactions, resulting in better nanotube in the EVA, that is consistent with the presence of large aggregates in the EVA/5H binary composite without EVA-g-MA. The highest tensile modulus was achieved with EVA/EMA-7H nanocomposite, which is about 40 % higher as compared to neat EVA, but its toughness and tensile strength values were found to be relatively lower compared to EVA/EMA-5H with 5 phr Org-HNT. It was explained with formation of highly reinforced/stiffened EVA and EVA-g-MA phases at higher nanotube loading. Among the composites, the EVA/EMA-5H nanocomposite appears to have the best composition, with the highest tensile strength and toughness as well as a tensile modulus that is about 30% higher than that of EVA. The nanocomposites had higher storage modulus values at 25°C and temperatures ranging from −50°C to 0°C when compared to neat EVA. The EVA/EMA-5H exhibited about 110 % higher storage modulus and higher damping parameter than neat EVA at 25°C. The same nanocomposite showed highest creep recovery rate with the lowest permanent deformation in accordance with its high dynamic modulus, indicating that the EVA/EMA-5H nanocomposite with a more optimal composition and elastic character, provides better hardness-toughness/damping balance.
The Effectiveness of Cause-Related Marketing: A Meta-Analysis on Consumer Responses
Authors: Schamp Christina , Heitmann Mark , Bijmolt Tammo H.A. , Katzenstein Robin
Published: June 2022

Cause-related marketing (CM), which links corporate donations to consumer purchases, has ongoing momentum in marketing. As the magnitude and direction of consumers’ response to CM are inconclusive, this meta-analysis synthesizes evidence on main and moderator effects from 237 studies. On average, the authors find a moderate effect for attitudinal response (d = .458) and a weak effect for behavioral response (d = .283; both ps < .001), both with high underlying heterogeneity. A multivariate meta-regression on CM moderators grounded along four conceptual pillars—transparency, signals of sincerity, purchase context, and consumers’ emotional attachment to CM—shows that attitudinal effects hinge mostly on emotional attachment. Suboptimal execution and poor communication of the donation appeal in particular can even have detrimental effects on attitudes. In addition, various moderators from other pillars play a relevant role. For behavioral outcomes, both emotional attachment and signals of sincerity are equally important. The visual prominence of the donation is the most relevant individual moderator, with only a few others related to the two pillars following at some distance. Therefore, CM requires different priorities depending on corporate objectives. This research further compares the effects of CM with those of discounts and other corporate social responsibility marketing instruments, simulates practical examples, and provides avenues for further research.
The Staunton case revisited
Authors: Nicholson Dr Geoffrey
Published: June 2022

In 1877 Harriet Staunton died in Penge, Kent, and four members of her family were convicted of her murder by malicious starvation. The defence attempted to show that she had died from tuberculous meningitis, but reappraisal of the evidence leads to the conclusion that she died from tuberculous Addison’s disease and that the defendants were wrongly convicted.
Awareness of Imminent Death: Results From a Mixed Methods Study of Israeli Family Caregivers’ Perceptions of Their Awareness and That of the Patients for Whom They Cared
Authors: Cohen-Mansfield Jiska , Cohen Rinat , Brill Shai
Published: June 2022

We studied levels of awareness of impending death in older patients and their family caregivers. Using a mixed methods approach, we interviewed 70 family caregivers in Israel. Of the caregivers, 64% reported having been aware of the impending death, 33% were unaware, and 3% uncertain. Caregivers reported their perception that 36% of patients were aware, 27% unaware, and for 37% they were uncertain about the patient’s awareness. Mechanisms that increased caregivers’ awareness were specific diagnosis, significant deterioration in health, preparation by a health professional, or patient preparations for death. This study clarifies processes which aid awareness, and the relationship between awareness and actual preparation for dying.
A constructivist approach to teach neuroanatomy lab: Students’ perceptions of an active learning environment
Authors: Hassan Sherif S. , Nausheen Fauzia , Scali Frank , Mohsin Hina , Thomann Charity
Published: June 2022

Background

A recent trend in medical education is developing a more dynamic and integrated curriculum. Team-based learning (TBL) increases students’ engagement and the active construction of anatomical knowledge. This initial study aimed to empirically observe medical students’ perceptions of their achievement of learning outcomes and the construction of their neuroanatomy knowledge, critical thinking, and problem-solving using an interactive whiteboard (IWB) as a teaching strategy.

Methods

An independent neuroanatomy lab survey collected students’ perceptions and comments about their learning experiences using the IWB on a questionnaire using a 5-point Likert scale.

Results

Student participants felt that using the IWB has facilitated their learning experience. 94.2% of student participants endorsed feelings that new technology has helped them achieve their learning outcomes, helped them integrate both their basic science and clinical science/skills knowledge (90.4%), enhanced their problem-solving skills (92.3%), facilitated their interaction with the neuroanatomy faculty (96.2%) and increase their critical thinking (88.4%).

Conclusion

Collecting such empirical data about students’ perceptions and their learning environment should help neurosciences faculty in medical schools better outline their activities to faculty at other medical institutions. Applying these methods may enhance the learning process, save time during neuroanatomy lab, and it could also help overcome the shortage of qualified neuroanatomy educators.

Mobility, Translocality and Social Reproduction during COVID-19: Migrant Workers in Narela Industrial Estate, Delhi
Authors: Chaudhary Tanya
Published: June 2022

The reverse migration of workers at the beginning of the first lockdown during the COVID-19 pandemic forcefully crystalised underlying issues such as poverty, hunger and the precarious lives of the working class in India’s megacities. With the easing of lockdowns, workers are again on the move. Against this background, this article aims to examine and unpack the reasons that have shaped labour mobility during the ongoing pandemic. It uses the framework of mobility studies and translocality which provide a strong analytical framework to understand linkages between rural and urban areas. In the process, the article highlights the politics associated with the mobility of workers. It draws on a case study of a peripheral industrial region of Delhi known as Narela. After briefly situating the study in the historicity of Narela with respect to the Industrial Relocation Policy of Delhi and resettlement of bastis, it highlights the lived experiences of the working-class population during and after the first lockdown of the pandemic. Based on detailed in-depth telephonic interviews, the article reiterates the crucial relationship between spatially stretched social reproduction and the social embeddedness of workers which suggests that there are a host of factors affecting workers’ mobility.
Testing the Waters: Young Women’s Work and Mobile Aspirations in India’s Small Cities
Authors: Naik Mukta
Published: June 2022

While metropolitan cities are framed as emancipatory spaces for women migrants, we know less about their experiences in smaller cities, which are driving urban transformation in India. Drawing on pre-pandemic fieldwork with employed youth (aged 15–29 years) in Mangalore and Kishangarh, this article investigates young women’s work, education, aspirations and mobilities in smaller cities which have relatively weak scalar positions in terms of global economic, political and social power. This article finds that small cities act as regional action spaces for women from villages and small towns to capitalise on fleeting opportunities and push against patriarchal boundaries through mobilities. It shows how women use a range of strategies from individual power tactics within households to leveraging institutional support systems to do so. The article suggests that situating migrant-friendly policy initiatives in small cities can potentially improve employment and mobility outcomes for young women.

Religiosity/spirituality and mental health: Evidence of curvilinear relationships in a sample of religious people, spirituals, atheists, and agnostics
Authors: Gontijo Daniel Foschetti , Silva Daniel Márcio Rodrigues , Damásio Bruno Figueiredo
Published: June 2022

There is much evidence that the relationship between religiosity/spirituality (R/S) and mental health is linear and positive, but relatively few studies have included samples of non-religious participants in their analyses. Some findings suggest that, compared to people who have intermediate levels of R/S, those with higher levels and those with insignificant levels are mentally healthier. However, this curvilinear model does not appear to have been tested through a measure of spiritual beliefs (i.e. belief in spiritual beings) and the comparison of different religious/spiritual groups. In view of this, 1788 Brazilians were assessed in terms of their spiritual beliefs, their religious/spiritual experiences (R/SE), and their positive (happiness and meaning in life) and negative (symptoms of anxiety and depression) mental health components. We found curvilinear relationships between R/SE and all components of mental health, but the level of spiritual belief predicted only the variance in the meaning in life. With the exception of comparisons involving happiness, at least one of the groups that had intermediate levels of R/SE (spirituals and agnostics) had worse mental health than the groups that had the highest and lowest levels (religious people and atheists, respectively). Although religious people and atheists had similar levels of symptoms of anxiety and depression, the former presented more happiness and meaning in life. Together, these findings corroborate the curvilinear model, but suggest that R/SE is related in different ways to the positive and negative components of mental health.
The Development and Validation of the Practicing Faith Survey
Authors: Cheng Albert , Green Beth , Smith David
Published: June 2022

We introduce a new instrument, called the Practicing Faith Survey (PFS), to assess faith formation among students in K-12 Christian schools. We begin by describing the conceptual and theological background of the PFS, underscoring the ways it differs from existing instruments of faith formation because of its particular focus on Christian practice within the context of learning and the vocation of the student. We then describe the procedures behind developing the PFS and its five domains: Intellectual, Relational, Introspective, Beneficent, and Formational Practices. We then provide evidence of validity and reliability based on a pilot study that involved 1,200 US and Australian Christian school students in fifth through 12th grades. We conclude with recommendations about how Christian school educators, students, and parents can use the PFS in practice.
Boredom at the end of history: ‘empty temporalities’ in Rousseau’s Corsica and Fukuyama’s liberal democracy
Authors: Daly Eoin
Published: June 2022

In this paper, I consider what it might mean to approach boredom as a problem of post-history, rather than of modernity as such. Post-history, or ‘end of history’, in this sense, is linked with the impossibility or unlikelihood of political-systemic change, and thus with the disappearance of the contingency or temporal flux that had been understood as the context or prerequisite of political action and political freedom. I will, argue, firstly, that both Rousseau and Fukuyama depict societies that are ‘post-historical’, in this sense, and which are marked by ‘boredom’ of this specifically post-historical kind. Secondly, I will argue that both thinkers link post-historical boredom with the disappearance or diminution of the ‘drive for recognition’ that both understood as both an agent and effect of ‘history’. Thirdly, I will argue that while Fukuyama understands post-historical boredom as an ‘irritant’ that threatens to restart history without quite succeeding in doing so, Rousseau understands it as an essentially stabilising (and happy) condition that maintains post-historical man in an equilibrium modelled on the order of nature itself. And fourthly, I consider certain ways in which this ‘post-historical’ boredom might coexist and overlap with the ‘promise of intensity’ experienced in post-Fordist neoliberal society.
Society of Toxicologic Pathology Neuropathology Interest Group Article: Neuropathologic Findings in Nonhuman Primates Associated With Administration of Biomolecule-Based Test Articles
Authors: Bangari Dinesh S. , Lanigan Lisa G. , Goulet Felix , Siso Silvia , Bolon Brad
Published: June 2022

The increasing specificity of novel druggable targets coupled with the complexity of emerging therapeutic modalities for treating human diseases has created a growing need for nonhuman primates (NHPs) as models for translational drug discovery and nonclinical safety assessment. In particular, NHPs are critical for investigating potential unexpected/undesired on-target and off-target liabilities associated with administration of candidate biotherapeutics (nucleic acids, proteins, viral gene therapy vectors, etc.) to treat nervous system disorders. Nervous system findings unique to or overrepresented in NHPs administered biomolecule-based (“biologic”) test articles include mononuclear cell infiltration in most neural tissues for all biomolecule classes as well as neuronal necrosis with glial cell proliferation in sensory ganglia for certain viral vectors. Such test article-related findings in NHPs often must be differentiated from procedural effects (e.g., local parenchymal or meningeal reactions associated with an injection site or implanted catheter to administer a test article directly into the central nervous system) or spontaneous background findings (e.g., neuronal autophagy in sensory ganglia).
A comparison of the nutritional content and price between dairy and non-dairy milks and cheeses in UK supermarkets: A cross sectional analysis
Authors: Glover Alex , Hayes Helen E. , Ni He , Raikos Vassilios
Published: June 2022

Background: Non-Dairy (ND) food consumption is rapidly increasing in the UK and for many consumers plant-based diets are presumed to be healthier than standard diets. ND alternatives have different nutritional compositions, and their consumption could present challenges on a public-health level. Aim: To compare the price and nutritional composition of dairy and ND milks and cheeses in UK supermarkets. Methods: Macro and micronutrient data was recorded from Alpro's website and the 6 leading UK grocers for their own-label ND milks and cheeses. For missing micronutrient values the McCance & Widdowson's dataset was used. 99 total products were extracted: 57 ND milks, 7 dairy milks, 10 dairy cheeses and 25 ND cheeses. Dairy milk and cheese were used as control against which all ND products were compared. Results: Soya and coconut milks had lower values of carbohydrates, sugars, calcium, iodine, and potassium ( p < 0.01) than dairy. Almond milk had lower values of carbohydrates ( p = 0.01), sugars, calcium, iodine, and potassium ( p < 0.01) compared to dairy milk. Protein was significantly ( p < 0.01) lower for all ND except soya. Dairy cheeses had higher values for energy, protein, iodine, potassium, riboflavin, vitamin B12 and calcium ( p < 0.01) than ND. Median prices were similar between dairy and ND milks, whereas ND cheeses were significantly more expensive compared to dairy ( p < 0.01). Conclusions: ND alternatives fall short in several key nutrients compared to dairy. Fortification, accurate labelling and nutrition education are needed to help consumers make healthy and informed choices.
Patterns of Childhood Adversities and Their Associations With Adult Victimization Among Incarcerated Men and Women in Spanish Prisons
Authors: Aizpurua Eva , Caravaca-Sánchez Francisco , Wolff Nancy
Published: June 2022

Adverse childhood experiences (ACEs) are prevalent and have long lasting effects. There is evidence of gender differences in exposure to different types of ACEs, with women experiencing higher levels of sexual abuse and cumulative adversity than men. Despite this, most research examining patterns of adversities have used joint samples, assuming that men and women have comparable profiles. The current study examines if distinct profiles of childhood adversities exist for men and women and analyzes their associations with multiple forms of interpersonal victimization during adulthood. Participants were 2,709 residents (91.6% men and 8.4% women) from eight prisons in Spain, who completed a self-administered survey. Latent Class Analysis revealed different patterns of childhood adversities for men and women. For both groups, higher adversity was associated with interpersonal harm during adulthood.
Investigating autonomic biomarkers of sensory processing patterns in young adults
Authors: Kerley Lachlan , Meredith Pamela , Harnett Paul
Published: June 2022

Introduction

Autonomic nervous system functioning is theorised to underpin individual differences in sensory processing, with a small amount of supporting evidence. Despite recognition of the need to measure the balance between sympathetic and parasympathetic activity, most studies have measured only one of these systems. This study investigated whether sensory processing patterns are related to autonomic balance for young adults at rest and in response to a sensory-based stressor.

Method

In this cross-sectional laboratory study, 100 young adults completed the adolescent/adult sensory profile. Heart rate variability and pre-ejection period were recorded before, during and after a coldpressor task.

Results

Relationships between sensory processing patterns and autonomic balance varied by gender. In males, low sensory thresholds were generally related to a state of reciprocal sympathetic activation. In females, low thresholds were associated with greater autonomic reactivity in response to the coldpressor.

Conclusion

This study showed, for the first time in young adults, that sensory processing patterns may be linked to patterns of autonomic balance. Therapists should be aware that young men with low sensory thresholds may be more likely than others to exhibit a resting state of sympathetic hyperarousal and further research should investigate whether this impacts their daily functioning and wellbeing.
Impact of a PMSG inter-turn short-circuits fault on a grid-connected variable-speed wind energy conversion system
Authors: Krim Youssef , Abbes Dhaker
Published: June 2022

This paper assesses the effect of an inter-turn short circuit fault in stator windings of a Permanent Magnet Synchronous generator (PMSG)-based variable speed wind energy conversion system (WECS) connected to the grid by a power converters interface. The objective is to assess the impact of the fault on the WECS performances. This study has two tasks. The first one details a dynamic modeling of different subsystems of the WECS. The mathematical model of the defective PMSG is also set up. The second one presents an appropriate control strategy for the power converters interface. The control of the PMSG-side converter aims to ensure the operation in maximum power point tracking. The grid-side control was also established by controlling the active and reactive powers to ensure the operation in unity power factor and keeping the DC bus voltage stable. The performance of the control design was tested under healthy and faulty conditions.
Assessment of personal inhalation and skin exposures to polymeric methylene diphenyl diisocyanate during polyurethane fabric coating
Authors: Harari Homero , Bello Dhimiter , Woskie Susan , Redlich Carrie A
Published: June 2022

Methylene diphenyl diisocyanate (MDI) monomers and polymeric MDI (pMDI) are aromatic isocyanates widely used in the production of polyurethanes. These isocyanates can cause occupational asthma, hypersensitivity pneumonitis, as well as contact dermatitis. Skin exposure likely contributes toward initial sensitization but is challenging to monitor and quantitate. In this work, we characterized workers’ personal inhalation and skin exposures to pMDI in a polyurethane fabric coating factory for subsequent health effect studies. Full-shift personal and area air samples were collected from eleven workers in representative job areas daily for 1–2 weeks. Skin exposure to hands was evaluated concomitantly with a newly developed reagent-impregnated cotton glove dosimeter. Samples were analyzed for pMDI by liquid chromatography-tandem mass spectrometry. In personal airborne samples, the concentration of 4,4′-MDI isomer, expressed as total NCO, had a geometric mean (GM) and geometric standard deviation (GSD) of 5.1 and 3.3 ng NCO/m3, respectively (range: 0.5–1862 ng NCO/m3). Other MDI isomers were found at much lower concentrations. Analysis of 4,4′-MDI in the glove dosimeters exhibited much greater exposures (GM: 10 ng/cm2) and substantial variability (GSD: 20 ng NCO/cm2; range: 0–295 ng NCO/cm2). MDI inhalation exposure was well below occupational limits for MDI for all the job areas. However, MDI skin exposure to hands was substantial. These findings demonstrated the potential for substantial isocyanate skin exposure in work settings with very low airborne levels. This exposure characterization should inform future studies that aim to assess the health effects of work exposures to MDI and the effectiveness of protective measures.

Published: June 2022

Objective

In many institutions, intensive care unit (ICU) nurses assess their patients’ muscle function as part of their routine bedside examination. We tested the research hypothesis that this subjective examination of muscle function prior to extubation predicts tracheostomy requirement.

Methods

Adult, mechanically ventilated patients admitted to 7 ICUs at Beth Israel Deaconess Medical Center (BIDMC) between 2008 and 2019 were included in this observational study. Assessment of motor function was performed every four hours by ICU nurses. Multivariable logistic regression analysis controlled for acute disease severity, delirium risk assessment through the confusion assessment method for the ICU (CAM-ICU), and pre-defined predictors of extubation failure was applied to examine the association of motor function and tracheostomy within 30 days after extubation.

Results

Within 30 days after extubation, 891 of 9609 (9.3%) included patients required a tracheostomy. The inability to spontaneously move and hold extremities against gravity within 24 h prior to extubation was associated with significantly higher odds of 30-day tracheostomy (adjusted OR 1.56, 95% CI 1.27−1.91, p < 0.001, adjusted absolute risk difference (aARD) 2.8% (p < 0.001)). The effect was magnified among patients who were mechanically ventilated for >7 days (aARD 21.8%, 95% CI 12.4−31.2%, p-for-interaction = 0.015).

Conclusions

ICU nurses’ subjective assessment of motor function is associated with 30-day tracheostomy risk, independent of known risk factors. Muscle function measurements by nursing staff in the ICU should be discussed during interprofessional rounds.
Evolution of motion of a rigid body similar to Lagrange top under the influence of slowly time varying torques
Authors: Leshchenko Dmytro , Ershkov Sergey V , Kozachenko Tetiana A
Published: June 2022

Perturbed rotational rigid body motions similar to the case of Lagrange top subjected to restoring and perturbation slowly time-varying torques of forces are studied in this paper. The restoring torque also depends on the small angle of nutation. The following problem is formulated in the current research: analyzing the solution’s behavior of system of motion equations for the values of small parameter different from zero on a sufficiently large interval of time. An averaging method is used for solving the problem. We have established the terms for feasibility to average (with respect to phase of nutation angle) the equations of rigid body motion related to Lagrange case. The averaged system of equations is received in the first approximation. Asymptotic approach permits to obtain some qualitative results and to describe evolution of motion using simplified averaged equations. In the case of rotational motion of a body immersed in the linear-dissipative medium, the numerical integration of the averaged system of equations is conducted. A new class of rotational motions of the Lagrange top is studied for an unsteady perturbation torque, as well as restoring torque that slowly varies with time and depends on the small nutation angle. These results are an extension of our former works (in the absence of slow time τ in the expressions for μ and M i or μ, where M i are dependent on τ only).

Acrylate monomer ((4-(3-(4-((4-(4-(3-(2,4-dichlorophenyl)-3-oxoprop-1-en-1-yl)phenoxy)-6-((4-nitrophenyl)amino)-1,3,5-triazin-2-yl)oxy)phenyl)-3-oxoprop-1-en-1-yl)phenyl acrylate (DTCP) is prepared and used to prepare poly (DTCP) and its copolymer poly (DTCP-co-HEA) and poly (DTCP-co-S) using 2-hydroxyethyl acrylate (HEA), styrene (S) by solution polymerization technique. Infrared spectroscopy (FT-IR), proton Nucleharmar Magnetic Resonance (1H NMR), and UV-Visible techniques are used to identify the synthesized polymers. Gel permeation chromatography method is used to determine the polymer’s weight average molecular weight, which is found to be around 10000 g/mol. According to the Thermo Gravimetric Analysis study, the synthesized polymers go through single stage decomposition centered at 340°C. The polymer reactivity ratio is found using well known Finemann-Ross (F-R), Kelen-Tudos (K-T), and extended Kelen-Tudos (ex.K-T) methods. The reactivity of the commercial monomers (HEA or S) is found to be higher than that of synthesized monomer, according to our findings. The photocrosslinking rate of the synthesized polymers is determined using a UV visible spectroscopic method and found to be high for polymer having HEA unit.
Impact of Digital Payment on Business Performance: A Study of Street Vendors in Odisha
Authors: Panda Shradhanjali , Sahoo Ansuman
Published: June 2022

A paradigm shift in the Indian banking sector coping with the technological transformation has led to a sharp rise in digital payments and receipts. The nation is witnessing a significant growth rate of around 30% ( Kumari, 2020 ) in digital payment, and receipts helping the economy move towards a cashless era. In this study, street vendors are considered. This article aims to examine the level of digital payment awareness among street vendors and its impact on their business performance. To work on this purpose, data are collected from three tier 2 cities, that is, Cuttack, Khurda and Berhampur in Odisha using both structured questionnaires and the interview method. Furthermore, this empirical study incorporates both primary and secondary data in order to provide an appropriate response to the above-mentioned goal. Collected data are analysed using statistical measures, such as gap study, principal component analysis, ANOVA and regression method. Findings of the study reveal street vendors are a financially excluded segment of the economy. An in-depth analysis of the result shows there is a strong association between the identified aspects of digital payment awareness and business performance of street vendors. The paper concludes by citing the managerial implication of its findings.
An Organizational Change Perspective for the Curriculum Internationalization Process: Bridging the Gap Between Strategy and Implementation
Authors: van den Hende Franka , Whitsed Craig , Coelen Robert John
Published: June 2022

Following a rapidly changing external environment, internationalization has become an institutional phenomenon with strategic relevance for universities worldwide. However, the frequently reported gap between theory and practice remains. Engaging staff and achieving successful organizational implementation appears increasingly problematic with more stakeholders and disciplines involved. This study explores the long-time gap between strategy and implementation with Pettigrew's organizational change framework (1987). We conducted a systematic scoping literature review of articles about curriculum internationalization ( N = 325) published in English in peer-reviewed journals between 2000 and 2022. Our study demonstrates that the organizational change perspective provides guidelines to improve and facilitate the process. Based on an organizational change perspective we developed a comprehensive framework that may contribute to more effective strategies for staff engagement and meaningful implementation outcomes for curriculum internationalization in higher education.
Who Has the Right to the Coworking Space? Reframing Platformed Workspaces as Elite Territory in the Geomedia City
Authors: Fast Karin
Published: June 2022

Current research suggests that coworking spaces (CWS) both respond to and legitimize work precarization. This is an important critique. Less acknowledged, however, is the fact that CWS also (re)produce eliteness. Thus, to the aim of offering perspectives that remain underrepresented in CWS research, I here scrutinize CWS as promotors of class privilege. I build my case on the premise that class privilege has to do with more than merely economic superiority and seek to dismantle, in particular, the role of geomedia technologies in the (re) production of CWS eliteness. With clues derived from a literature review as well as analyses of real-life cases, I here recognize CWS as places of elite (non-)consumption, as hubs of elite mobility, as nodes in elite networks, and, ultimately, as elite territories in the (super-)gentrified geomedia city. I end my article by reflecting on the dialectics of CWS eliteness, thereby suggesting how precariousness and eliteness are interlinked.
“Music is my life”: Examining the connections between music students’ workload experiences in higher education and meaningful engagement in music
Authors: Jääskeläinen Tuula
Published: June 2022

Enhancing our knowledge about students’ experiences during their studies in higher music education is essential to understand and support them as they cope with their specific workloads in studying music. This study provides a research-based understanding of what engaging in music means to music students when they reflected on their experiences of their studies and workloads. The data were collected from interviews with 29 students in higher music education institutions in Finland and the United Kingdom, and the analysis was conducted by following the framework of transcendental phenomenology. Music students’ experiences of their workload are connected in multifaceted ways to the meanings they ascribe to their engagement in music, such as intense and complex experiences that are also a source of vitality, their development as musicians, their creative self-expression, their interaction with others and in building a community, their personal growth and coping approaches during their studies, and the transcendental experiences they encounter during their engagement with music. Thus, the findings indicate that engaging in music is a holistic experience for music students. This study shows the importance of understanding and investing in music students’ unique workload experiences through research on the teaching and learning practices of higher music education institutions, which can in turn support music students’ well-being, learning, and future careers.
I’ll never forget: Remembering of past events within the Silent Generation as a challenge to the political mobilisation of nostalgia
Authors: Nieland Sue , Mahendran Kesi , Crafter Sarah
Published: June 2022

The political mobilisation of nostalgia is increasingly preoccupying social and political psychologists. A key concern is with rising populism and the use of an imagined golden past to foster threat through anti-EU and anti-immigrant sentiment. This article introduces two key concepts, anemoia – imagining a past not experienced – and prolepsis – how the past influences actions in the present aligned to future goals – to argue that actual recall of past biographical events potentially counters the influence of nostalgic rhetoric designed to influence political decision-making. The focus of this article is a single Scottish case study, Rachel, a member of the Silent Generation of citizens aged over 75 years, who have a living memory of World War II and its aftermath. A dialogical analysis was carried out identifying key I-positions and chronotopic analysis of the dialogical self, relating to experienced extreme childhood poverty and deprivation, anti-Semitism and limited mobility. This demonstrated how living through a historic event and its repercussions, rather than imagining a past not experienced, mitigates against nostalgia. This raises the question of how much mobilisation of the events of a glorious past and anxieties about the future rely upon the unexamined silence of those who recall those same events.
Beyond populism: The diversity of thin anti-establishment contestation in turbulent times
Authors: Pytlas Bartek
Published: June 2022

Studies of ‘thin’ anti-establishment supply assess mainly the extent of populist messages. This paper analyses the diversity of thin contestation beyond just populism. I conduct a content analysis of 142 social media campaigns by anti-establishment (AEPs) and conventional parties during 23 elections across Europe 2010–2019. We find that in addition to popular will and extra-political technocratic expertise, AEPs increasingly enacted exceptional political calling, depicted as necessary to revive ‘true’ formal-representative politics itself. Regression analysis shows that political vocation cues played an important auxiliary role in AEP mobilization strategies. On average, those AEPs across the political spectrum which used more political vocation messages performed better electorally ceteris paribus than those which used them less. Conventional parties instead did not universally benefit if they increasingly spotlighted thin messages. The salience of anti-establishment and populism-related rhetoric played a further role within particular AEP groups, but neither was significantly associated with stronger AEP performance altogether. In order to better understand recent political turbulence, it is therefore useful to account for more diverse thin contestation supply.
Public elementary school teachers’ positioning in teaching physical education to Japanese language learners

Published: June 2022

The purpose of this study was to describe and explain Japanese generalist elementary teachers’ experiences teaching physical education (PE) to Japanese language learner (JLL) children in public schools in Japan. Participants were seven public elementary school teachers (two females and five males) who had experience teaching JLL children. Data sources included a demographic questionnaire, online semi-structured interviews, and follow-up email interviews. Framed in positioning theory, three themes were identified from the data analysis: (a) seeking PE lesson ideas from observing children's performance in other academic subjects, (b) learning how to interact with parents of JLL children, and (c) accommodating JLL children's cultural and behavioral differences in PE. The findings indicate that all seven Japanese public elementary teachers experienced a wide range of physical, emotional, and social struggles when they taught JLL children in PE class. This study suggested that PE has the potential to enrich teachers’ and children's cultural awareness and mutual understanding and as a tool to raise awareness of social justice and diversity.

Introduction

Farmers have a high risk for depression (MDD). Preventive measures targeting this often remotely living population might reduce depression burden. The study aimed to evaluate the effectiveness of personalized telephone coaching in reducing depressive symptom severity and preventing MDD in farmers compared to enhanced treatment as usual (TAU + ).

Methods

In a two-armed, pragmatic randomized controlled trial ( N = 314) with post-treatment at 6 months, farming entrepreneurs, collaborating family members and pensioners with elevated depressive symptoms (PHQ-9 ≥ 5) were randomized to personalized telephone coaching or TAU + . The coaching was provided by psychologists and consists on average of 13 (±7) sessions a 48 min (±15) over 6 months. The primary outcome was depressive symptom severity (QIDS-SR16).

Results

Coaching participants showed a significantly greater reduction in depressive symptom severity compared to TAU + ( d = 0.39). Whereas reliable symptom deterioration was significantly lower in the intervention group compared to TAU + , no significant group differences were found for reliable improvement and in depression onset. Further significant effects in favor of the intervention group were found for stress ( d = 0.34), anxiety ( d = 0.30), somatic symptoms ( d = 0.39), burnout risk ( d = 0.24–0.40) and quality of life ( d = 0.28).

Discussion

Limiting, we did not apply an upper cutoff score for depressive symptom severity or controlled for previous MDD episodes, leaving open whether the coaching was recurrence/relapse prevention or early treatment. Nevertheless, personalized telephone coaching can effectively improve mental health in farmers. It could play an important role in intervening at an early stage of mental health problems and reducing disease burden related to MDD.

Plastic fantastic: Sex robots and/as sexual fantasy
Authors: Karaian Lara
Published: June 2022

This article provides an interdisciplinary and intersectional analysis of sex robots and/as sexual fantasy. I demonstrate that sexual fantasy is a highly complex and salient vector of analysis for any discussion of love and sex with robots. First, I introduce contemporary North American sex robots and offer a brief sketch of their ontology as relates to sex toys and pornography. Next, I provide a short but instructive mapping of sexual fantasy scholarship from across the fields of experimental psychology, media and cultural studies, post-colonial, psychoanalytic, feminist, queer and critical race theory. My goal here is to demonstrate sexual fantasy’s polymorphous and productive nature and its complex relationship to reality. Drawing on the theories of sexual fantasy canvassed herein, I examine the role of fantasy to sex robots’ inception, marketing, and consumption. From here I offer an appraisal of radical feminist, new materialist, and disabled queer and trans feminists’ critiques of sex robots and their users. I argue that theorizing sex robots through the lens(es) of sexual fantasy is necessary given efforts to stigmatize, regulate, and criminalize sexual fantasy and sextech users in the post/digital age. Future scholarship is encouraged to further examine the sex robot/sexual fantasy nexus and to consider whether and how their intersections impede or facilitate the development of alternative “networks of affection” including those that lie between the platonic and romantic or between “carbonsexuality” and technosexuality/digisexuality.

Published: June 2022

This study investigated the impact of cyberbullying victimization at work on well-being and strain in the workplace. This is the first study to use a longitudinal approach to research cyberbullying at work. A nationally representative sample of Finnish workers ( n = 768) took part in a five-wave survey study. Both within-person and between-person effects were analyzed using hybrid regression models showing that experiencing cyberbullying at work leads to psychological distress, technostress, work exhaustion, and decreased work engagement. The effects of remote work and social media use were also explored. These results confirm that cyberbullying at work can have damaging consequences for victims and, consequently, for whole organizations. Thus, it constitutes a significant problem that employers must confront.
‘How do I become blue pilled?’: Masculine ontological insecurity on 4chan’s advice board
Authors: Maloney Marcus , Roberts Steve , Jones Callum
Published: June 2022

Through an analysis of 4chan’s /adv/ or ‘advice’ board – in which predominately male users seek advice on life matters – here we examine masculine ontological insecurity and its implications for understanding how ‘toxic’ masculine identities emerge, and how young men more generally struggle to make sense of their lives. Advancing extant scholarship, our findings uncover an ‘on the cusp’ masculine identity – subject to the anxieties and self-perceived failures which act as preconditions of toxic ideologies and outcomes, but also seemingly yet to practice such (il)logics. Responses from the community suggest three ways of addressing, or making sense of, the problems users faced. Finally, and of relevance to both the theorising of contemporary masculinities and related socio-positive interventions, we highlight the (seemingly) odd paradox of vulnerable male users being drawn to express their vulnerabilities on a platform notorious for its insensitivities.
