Self-Actualization and the Integration of Psychedelic Experience: The Mediating Role of Perceived Benefits to Narrative Self-Functioning
Authors: Amada Nicole , Shane Jacob
Published: June 2022

There is a growing need in the field of psychedelic science for a unifying perspective of overall well-being to join seemingly disparate findings across clinical and non-clinical populations, and account for the unique role of post-psychedelic integration for promoting benefits. According to the eudaimonic perspective of well-being, the stories we create about who we are (self-insight) and who we can become (personal development) are key aspects of narrative self-functioning that either constrain or facilitate well-being. The present paper draws upon this perspective to investigate the relationship between extent of post-psychedelic integration and optimal well-being ( self-actualization), with perceived benefits to narrative self-functioning ( self-insight and personal development) as a mediator. The data for testing this model was collected from roughly 750 participants recruited from websites and social media forums. Because the sample contained clinical and non-clinical individuals, the model was able to be tested with mental health condition as a moderator. Results indicated that perceived benefits to narrative self-functioning is one pathway through which integration of psychedelic experience may promote optimal well-being for both clinical and non-clinical populations. Exploratory analyses indicated that integration techniques that are more self-referential in nature are the ones that indirectly relate to optimal well-being via perceived benefits. The results of the present study should be interpreted as a preliminary model for future longitudinal research to test, as our cross-sectional methods preclude any causal inferences to be made from these mediation analyses.

Published: June 2022

Objectives: Reverse transcriptase-polymerase chain reaction (RT-PCR), the reference laboratory method of confirmed SARS-CoV-2 diagnosis, though requiring equipment, is time-consuming. There is a crucial demand for rapid techniques such as antigen detection test during the pandemic. This study assessed whether a rapid antigen detection (RAD) test was an effective and essential method for the early diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the COVID-19 pandemic. The probability of public screening at home and the application of RAD during the novel SARS-CoV-2 outbreak were also topics of interest. Methods: A retrospective analysis based on the systemic screening for COVID-19 was conducted at Taipei City Hospital (TCH) from May 28 to June 06, 2021, the first week of outbreak in Taiwan. The results of the RAD and RT-PCR tests were collected from 5 major branches of the TCH. Results: We collected a total number of 6368 cases. We found that the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy ranged from 60.5% to 78.6% (mean 66.0%), 98.2% to 99.9% (mean 99.0%), 74.4% to 97.8% (mean 82.8%), 94.0% to 98.4% (mean 97.5%), and 93.8% to 98.3% (mean 94.2%), respectively. Although the sensitivity score was not high (up to 95% or higher), the other results were satisfactory, with an accuracy of more than 93% in all branches. Furthermore, it had high specificity, PPV, NPV, and accuracy. Conclusion:We concluded that RAD could be a quick and feasible method to identify individuals infected with SARS-CoV-2 from non-contagious individuals during the COVID-19 outbreak. A RAD test was an effective and essential method for the early diagnosis of SARS-CoV-2 during the COVID-19 pandemic.
The Fourth Transformation and the Trajectory of Neoliberalism in Mexico
Authors: Coughlin Richard W.
Published: June 2022

The 2018 electoral victories of Andrés Manuel López Obrador (hereafter, AMLO) and his political party, Morena, may represent a significant inflection point in the development of neoliberalism in Mexico. The trajectory of neoliberalism has unfolded in terms of what Nils Gilman refers to as the “twin insurgency”—a plutocratic insurgency that, since the 1970s, has been restructuring capitalism on a transnational basis and a criminal insurgency that has flourished within the denationalized social spaces of neoliberalism. López Obrador’s national project, termed “the Fourth Transformation,” is an effort to anchor processes of capital expansion in Mexico within a restoration of political community centered on AMLO’s policy agenda and political rhetoric. In a broader context, it is also a process of state transformation historically shaped by the twin insurgency and characterized by the emergence of new hybrid modes of organized violence.

Las victorias electorales de 2018 de Andrés Manuel López Obrador (en adelante, AMLO) y su partido político, Morena, pueden representar un punto de inflexión significativo en el desarrollo del neoliberalismo en México. La trayectoria del neoliberalismo se ha desarrollado en términos de lo que Nils Gilman llama la “insurgencia gemela”, una insurgencia plutocrática que, desde la década de 1970, ha reestructurado el capitalismo sobre una base transnacional y una insurgencia criminal que ha florecido dentro de los espacios sociales desnacionalizados del neoliberalismo. El proyecto nacional de López Obrador, denominado “la Cuarta Transformación”, es un esfuerzo por anclar los procesos de expansión de capital en México dentro de una restauración de la comunidad política centrada en la agenda política y la retórica política de AMLO. En un contexto más amplio, también es un proceso de transformación estatal históricamente moldeado por la insurgencia gemela y caracterizado por el surgimiento de nuevos modos híbridos de violencia organizada.
Neural network–based adaptive fractional-order terminal sliding mode control
Authors: Hou Shixi , Wang Cheng , Chu Yundi , Fei Juntao
Published: June 2022

This paper proposes an adaptive fractional-order (FO) terminal sliding mode control (TSMC) scheme to the robust current control of active power filter (APF) using a recurrent meta-cognitive fuzzy neural network (RMCFNN). An FO TSMC is developed by considering that the parametric perturbations and the external disturbances of APF are bounded. Compared with conventional TSMC approach, the proposed scheme, with an FO sliding surface, can obtain enhanced finite-time high-precision tracking performance due to another degree of freedom. Then, a novel observer-based FO TSMC is derived to achieve an absorbing model-free feature arising from RMCFNN. To improve the capabilities in managing the uncertainties, the specific online updating schemes for the structure and parameters of RMCFNN are designed. Meanwhile, closed-loop stability and finite-time convergence characteristic can be achieved using Lyapunov theory. Finally, simulation and experimental results indicate that the proposed observer-based FO TSMC can be easily implemented by microcontroller and has superior control performance compared with other existing schemes.

Published: June 2022

The neuropsychological profile associated with sex chromosome trisomies (SCT) is frequently characterised by delays or deficits in linguistic development. Although maternal input could have an important role in influencing and shaping the linguistic development of children with SCT, there is a lack of studies in the literature that have investigated its prosodic characteristics. The study aims to analyse the prosodic features of the maternal input addressed to a group of 8-month-old children with SCT and a group of typically developing (TD) peers. Nineteen mother–child dyads with children with SCT and 19 mother–child dyads with TD children participated in the study. Maternal utterances were collected during video-recorded play sessions, and for each dyad, 50 maternal utterances were selected and analysed using the software Praat. The results showed that the maternal input produced by the mothers in the SCT group was characterised by a significantly lower pitch, less marked and modulated melodic contours, and a shorter final syllable duration than the input addressed to TD children. The prosodic features found in the maternal input addressed to children with SCT were not those expected in the maternal input addressed to children at this developmental stage and could create a non-optimal linguistic environment.
Diversity in bilingual child language acquisition research: A commentary on Kidd and Garcia (2022)
Authors: Rochanavibhata Sirada , Marian Viorica
Published: June 2022

Kidd and Garcia report that language acquisition studies are skewed toward monolingual and English-speaking populations. This commentary considers Kidd and Garcia’s arguments in light of our research on mother-preschooler discourse and non-verbal communication in Thai monolingual and Thai-English bilingual children. We discuss lessons learned from testing linguistically diverse children and underscore the importance of research on non-WEIRD (Western, Industrialized, Educated, Rich, and Democratic) populations. We advocate for the inclusion of children who speak understudied languages and those who speak multiple languages in developmental science.
Customer Concentration and Managerial Bad News Withholding
Authors: Chen Yangyang , Hu Gang , Yao Jun , Zhao Jingran
Published: June 2022

We investigate whether the presence of major corporate customers affects managerial bad news withholding behaviors. Using data from a large sample of U.S. firms, we find that firms with a more concentrated customer base have a greater tendency to withhold bad news. Furthermore, we show an amplified effect of customer concentration on bad news withholding for firms that rely more on major customers and an attenuated effect for firms whose major customers would face higher costs to switch suppliers. We also show that the effect of customer concentration on bad news withholding is weaker for firms with stronger auditor monitoring. Overall, we find that a concentrated customer base imposes performance pressure on managers, which induces them to withhold bad news.
“I Didn’t Want Him to Disappear” Parental Decision-Making on Access to Puberty Blockers for Trans Early Adolescents
Authors: Horton Cal
Published: June 2022

Puberty can be a particularly challenging time for adolescents who are transgender. Access to puberty blocking medication, commonly called ‘puberty blockers', is considered an integral component of gender affirmative healthcare. Existing literature provides little insight into how parents of trans children entering into early adolescence navigate decision-making related to puberty blockers. This unique research examines parental perspectives on medical decision-making from a cohort of families with trans children who socially transitioned pre-adolescence (average age 7), and who at time of parental interview were in or approaching, early adolescence (average age 11). Data were analysed through inductive reflexive thematic analysis. Parental reflections are presented within three main themes, concern for protection of adolescent mental health and well-being, parental perspectives on adolescent consent, and managing decision-making without certainty. These findings hold relevance for healthcare policy makers, for parents of trans children, and for healthcare, social services and other professionals supporting trans adolescents and their families.
How musicality changes moral consideration: People judge musical entities as more wrong to harm
Authors: Agrawal Tanushree , Rottman Joshua , Schachner Adena
Published: June 2022

A growing literature shows that music increases prosocial behavior. Why does this occur? We propose a novel hypothesis, informed by moral psychology: evidence of others’ musicality may promote prosociality by leading us to judge musical individuals as having enhanced moral standing. This effect may be largely indirect, by increasing perceptions of how intelligent and emotionally sensitive musical individuals are. If so, simply knowing about others’ musicality should affect moral evaluations, such as wrongness to harm. Across four experiments (total N = 550), we found supportive evidence. Information that an animal or person had the capacity and motivation to engage with music led participants to judge these entities as more wrong to harm than matched neutral or non-musical counterparts. Similarly, knowing that a person was not musical made people judge them as less wrong to harm than neutral or musical counterparts. As predicted, musicality was positively associated with perceptions of capacities for emotionality and intelligence, and these broader factors partially mediated the relationship between musicality and wrongness to harm. These effects were not influenced by participants’ own musicality. Thus, non-moral attributes like musicality can impact moral consideration, carrying implications for social behavior and for interventions to promote prosociality.
Effects of alexithymia and its subfactors on emotional response to music
Authors: Liu Jingni , Fukushima Hirokata
Published: June 2022

Alexithymia is a trait characterized by decreased emotional response to visual or verbal stimuli. However, Lyvers et al. suggest that alexithymia is positively correlated with the magnitude of emotional response to music (ERM). This study reexamines their findings in two sets of Asian population (China [ n = 344] and Japan [ n = 341]) using online surveys to investigate the subfactors of alexithymia. The Toronto Alexithymia Scale and the Geneva Emotional Music Scale (GEMS) were used to measure alexithymia and ERM in the participants, along with trait anxiety and music experiences in their daily lives. The obtained data showed that in both the Chinese and the Japanese populations, individuals with higher alexithymia tend to have higher GEMS scores (i.e., higher ERM), which is consistent with the finding of the previous study. Furthermore, alexithymia and ERM are correlated because of difficulty in identifying feelings, a subfactor of alexithymia. These results were not influenced by trait anxiety. In addition, alexithymia showed no correlation with either the frequency of listening to music or the degree of music absorption in daily life. We argued that the nonverbal characteristic of music might be key to the association between alexithymia and ERM.
Sensorimotor synchronization with music and metronome in school-aged children
Authors: Carrer Luiz Rogério Jorgensen , Pompéia Sabine , Miranda Monica Carolina
Published: June 2022

Sensorimotor synchronization (SMS), the coordination of body movements with external stimuli (e.g., dancing, clapping along with music, sport activities), increases throughout childhood when assessed by finger-tapping (FT) tasks following rhythmic auditory cues using metronomes. However, metronomes may support less rhythmic entrainment than naturalistic auditory cues like music, so they may be less effective in showing developmental improvement. This study investigated the effects of age and sex on SMS comparing metronome versus music stimuli in four auditory FT tasks with regular fast (inter-stimulus interval [ISI] = 333 ms) and slow tempi (ISI = 1,000 ms). Participants were 305 typically developing children aged 6 to 11 years. We found improvement (lower variability) in performance with increasing age irrespective of the metronome or music FT and sex, particularly between 6 and 9 years, after which performance stabilized. Nonetheless, mostly irrespective of age, performance for music and metronome stimuli showed differences in synchronization accuracy and variability, indicating that the type of rhythmic stimuli affects performance. A developmental effect was also found in inter-tap variability (but not inter-tap accuracy). Overall, developmental effects were more robust in FT variability (motor implementation) although responses to music and metronome stimuli differed in ways that may be relevant to SMS deficits in clinical populations.
How to Measure the Network Vulnerability of Cities to Wildfires: Cases in California, U.S.A.
Authors: Yun Jeongin , Lee Jooyoung , Park Jangseop , Chung Koohong , Lee Jinwoo
Published: June 2022

This paper proposes a framework to evaluate the network vulnerability of cities to wildfires. Three cities are selected from the California Public Utilities Commission (CPUC), U.S., fire-threat regions: Orinda, Paradise, and Atascadero. For each city, four different network connectivity measures are calculated, and agent-based evacuation simulations are performed by the Monte Carlo method. In the simulations, the number of isolated vehicles and evacuation time estimates are measured for the following scenarios: (i) no wildfire case with original network; and (ii) wildfire cases with randomly damaged networks that are reduced by 1%, 3%, 5%, 7%, and 10% from the original network. A city-to-city comparison is conducted in relation to network connectivity measures and evacuation simulation results. It is shown that Paradise has the worst network connectivity, and the simulation results reveal that Paradise also has the most sensitive network in relation to random roadway closures caused by wildfire propagation. Thus, among the three cities, Paradise has the most vulnerable network to wildfires as determined through the two analysis results concerning the worst network measures and the simulation results. It is expected that the proposed analysis framework can be generally applied to any city located in a fire-threat region.

Published: June 2022

Background:

Patients with cardiogenic shock may require extracorporeal membrane oxygenation (ECMO) prior to durable mechanical circulatory support (dMCS) or heart transplantation (HTx).

Methods:

We investigated the clinical characteristics and outcomes of adult patients with ECMO support as bridge to dMCS or HTx between 1/1/13 and 12/31/20.

Results:

Of 57 patients who underwent bridging ECMO, 41 (72%) received dMCS (approximately half with biventricular support) and 16 (28%) underwent HTx, 13 (81%) after the 2018 UNOS allocation system change. ECMO → HTx patients had shorter ventilatory time (3.5 vs 7.5 days; p = 0.018), ICU stay (6 vs 18 days; p = 0.001), and less need for inpatient rehabilitation (18.8% vs 57.5%; p = 0.016). The 1-year survival post HTx was 81.3% in the ECMO → HTx group and 86.4% in the ECMO → dMCS group ( p = 0.11). For those patients in the ECMO → dMCS group who did not undergo HTx, 1-year survival was significantly lower, 31.6% ( p = 0.001).

Conclusion:

Patients on ECMO who undergo HTx, with or without dMCS bridge, have acceptable post-HTx survival. These findings suggest that HTx from ECMO is a viable option for carefully selected patients deemed acceptable to proceed with definitive advanced therapies, especially in the era of the new UNOS allocation system.
Synergistic effect of miR-9 overexpression and electrical induction on differentiation of conjunctiva mesenchymal stem cells into photoreceptor-like cells
Authors: Naderi Mahmood , Nadri Samad
Published: June 2022

A variety of genes and materials can induce the differentiation of stem cells. The purpose of this work was to investigate the effect of microRNA-9 (miR-9) overexpression and electrical induction on the photoreceptor differentiation of Conjunctiva Mesenchymal Stem Cells (CJMSCs). In this study, an electroconductive scaffold (silk fibroin polymer (SF) and reduced graphene oxide (rGo) nanoparticles) was fabricated by electrospinning method, and its characteristics such as diameter, graphene distribution, compound, conductivity, and toxicity were evaluated by scanning and transmission electron microscopy (SEM and TEM), FTIR, electrochemical impedance spectroscopy, and MTT assay. The cells were transduced by a lentiviral vector carrying miR-9, then electrical induction was implied on mir-9-CJMSCs, cultivated on the fabricated scaffold, and the expressions of neural and photoreceptor marker genes were evaluated by RT-qPCR. A uniform, smooth appearance with lower diameter, uniform distribution of rGo nanoparticles across the fibers, and lower resistance were shown in SF-rGo fibrous scaffold. After electrical stimulation, lower and higher expression of neural marker genes and photoreceptor marker genes (Rhodopsin, PKC) were documented, respectively. Finally, we proposed that the combinational approach of miR-9 overexpression and electrical induction leads CJMSCs to photoreceptor-like cells.
A Comparative Analysis of State Implementation of the Community First Choice Program
Authors: Beauregard Lisa Kalimon , Miller Edward Alan
Published: June 2022

The Patient Protection and Affordable Care Act included Community First Choice (CFC), a new optional Medicaid home and community-based services (HCBS) state plan benefit which states could adopt. Through the CFC program, states can provide expanded home and community-based attendant services and supports to older adults and persons with disabilities. A benefit of CFC is that states receive a higher federal match rate than other HCBS programs. Thus far, eights states have adopted CFC. This comparative case study analysis examines state-level implementation of CFC to identify what facilitated implementation and what created challenges. The results suggest that consulting with the Centers for Medicare and Medicaid Services facilitated implementation while existing programs, insufficient engagement with stakeholders, aggressive timelines, and limited staff resources presented challenges. Based on these findings, states may want to consider how they approach implementing expansions or enhancements to HCBS benefits under the American Rescue Plan Act.
The Dynamics of Intimate Relationships and Violent Victimization Among Young Women
Authors: Kusunoki Yasamin , Bevilacqua Kristin , Barber Jennifer S.
Published: June 2022

Despite the fact that intimate partner violence (IPV) occurs within intimate relationships, we know relatively little about the characteristics of those intimate relationships, and even less about how IPV changes across time within different relationships. We use the Relationship Dynamics and Social Life (RDSL) study, based on a random sample of 1003 18–19-year-old women residing in a Michigan county. Women were interviewed weekly for 2.5 years, resulting in an age range of 18 through 22. We estimate hybrid “within-between” regression models, which allows us to directly compare the same woman’s risk of experiencing IPV across her different relationships, varied in terms of resources, balance of power, conflict, childbearing, relationship type, and duration. Our analyses demonstrate that power imbalance in intimate relationships, non-monogamous and unstable relationships, relationships with men who are not the father of a woman’s existing children, and serious relationships (especially stayover and cohabiting) place young women in their late teens and early twenties at particularly high risk of multiple dimensions of IPV. Our fixed-effects modeling strategy isolated the increase in IPV risk that is due to these characteristics and experiences within intimate relationships from the risk due to young women being at high risk of IPV for other reasons who might tend to choose these types of relationships. The elevated risk of IPV in relationships with these characteristics and experiences supports a causal link between them. Our research supports the potential efficacy of interventions that reduce conflict, equalize power within relationships, and encourage women—especially young mothers—to delay serious relationships.
Associations Between Habitual Dietary Behaviors and Glutamic Acid Levels in Human Milk
Authors: Nakai Shoko , Tateoka Yumiko , Miyaguchi Yumiko , Takahashi Mari , Ogita Hisakazu
Published: June 2022

Background:

Glutamic acid, an amino acid that exhibits umami taste, is utilized in Japanese food and is abundant in human milk. We examined the influence of maternal habitual eating behavior on glutamic acid concentration in human milk.

Research Aim:

To determine the association between maternal dietary behaviors at the end of pregnancy and the 1st month postpartum and glutamic acid concentration in colostrum and mature milk.

Method:

This was a prospective, correlational, one-group longitudinal study. Women aged 20–30 years during the third trimester of pregnancy ( N = 30) consented to participate and completed the data collection. Dietary history questionnaires were used to measure food intake. Glutamic acid levels in whey from colostrum and mature milk and in plasma during late pregnancy and the first month postpartum were measured. Data were considered significant at p < .05. Basic statistics, correlation coefficients analysis, unpaired t test, and one-way analysis of variance were performed.

Results:

Glutamic acid concentrations in human milk and plasma were found to be significantly associated with the consumption of several different foods. There was no association between glutamic acid concentrations in human milk and plasma or between glutamic acid concentrations in colostrum and mature milk. The glutamic acid content of mature milk differed by physical activity level (mild and moderate) during the first month postpartum ( t [46] = 2.87, p < .01).

Conclusion:

There was no clear association between habitual dietary behavior and glutamic acid concentration in human milk. However, maternal factors other than diet may be important and require additional research.
Looking at the Sky: An Ethnographic Study of How Religiosity Influences Business Family Resilience
Authors: Azouz Ali , Antheaume Nicolas , Charles-Pauvers Brigitte
Published: June 2022

Despite the growing interest in resilience in the family business context, little attention has been devoted to understanding the influence of religion on the way business families respond to adverse environments. We use a unique ethnography of a Middle Eastern faith-led family firm to investigate how religiosity influences the way the business family resists and rebounds from environmental shocks. We identify religious role expectations as a pivotal driver of particularistic responses in family firms to advance a religious-based foundation for business family resilience.
Quantitative investigation of the head-hump of large-scale vaned-voluted centrifugal pump

Published: June 2022

In this study, the three-dimensional incompressible flow in a large-scale vaned-voluted centrifugal pump was numerically studied based on the Reynolds-averaged Navier–Stokes (RANS) method. As the flow rate increases, the vortices suddenly appear and disappear. These alternating vortices cause the instability region on the Q-H curve. Therefore, the local entropy production rate (LEPR) is analyzed for a better understanding. The LEPR method will provide a visualization of the energy change in unit and make it easier to understand the reasons of head-hump. Large-scale vaned-voluted centrifugal pumps are often used in large-scale water diversion projects. Long-time operation and frequent changes of conditions require the stability of pump performance, and the head-hump is an important factor that affects the stability of centrifugal pumps. The hump characteristics must be studied and the hump region should be avoided. Under small flow rate condition, six typical high LEPR situations in stay vanes are summarized. It is found that the vortex itself will not produce a large energy loss, the vortex causing high LEPR interacts with surrounding flow or wall. The flow interaction dominates LEPR in impeller and stay vanes. Zonal proportion of LEPR in impeller accounts for a higher proportion than stay vane. This study provides an effective way in understanding the mechanism of flow energy loss in the large-scale vaned-voluted centrifugal pump and can be referred to other similar turbomachinery cases.
Improved A-star algorithm based on multivariate fusion heuristic function for autonomous driving path planning
Authors: Wang Pengyu , Liu Yanglin , Yao Weimin , Yu Yuanbin
Published: June 2022

Path planning is a fundamental problem in the aspect of autonomous driving. A-star (A*) algorithm is a heuristic algorithm for path planning. However, there are two problems need to be solved in the traditional A-star algorithm: firstly, the tracking error caused by vehicle speed and vehicle size are not considered in path planning; secondly, the kinematics constraints of the vehicle itself and the smoothness of the path in the actual driving process are not considered. Therefore, this paper proposes an improved A-star algorithm to address the above deficiencies. By designing the collision cost heuristic function based on the position of obstacles, the vehicle contour and speed are considered and the vehicle safety is improved by setting a safe space around the vehicle, and establishing a steering cost heuristic function based on the control of heading angle difference, the vehicle dynamics constraints are satisfied, so as to improve the feasibility of path planning. The experimental results show that the improved A-star algorithm can avoid vehicle contours collision at different speeds and output a smoother path, and effectively generate higher quality path.
Aerodynamic performance characterization of bio-inspired wings with leading edge tubercles at low Reynolds number
Authors: Gopinathan V T , Ralphin Rose J Bruce
Published: June 2022

On the observation of biomimetic Humpback Whale (HW) flippers, the airfoil aerodynamic performance characteristics are explored. The Leading Edge (LE) tubercle geometry was inspired by the flipper of HW that has rounded LE protuberances and tapered trailing edge configurations. The tubercles have excellent flow control characteristics at the post-stall region. Aerodynamic characteristics of airfoils such as NACA0015 and NACA4415 with LE tubercles are experimentally and numerically investigated at the low Reynolds number about Re = 1.83 × 105. The bio-inspired modified airfoils (HUMP 0015 and 4415) are designed with the amplitude to wavelength ratio [Formula: see text] of 0.05. The numerical simulation over the modified airfoils shows that, at higher Angle of Attack the flow separation is delayed in the peak region whereas the early flow separation is observed in the trough region adjacent to the LE. The boundary layer flow separation analysis is done extensively through numerical simulations and the velocity vector profiles are captured at different chordwise positions. The stall delay phenomenon is observed through the outcome of this research that specifically insists at the peak region of tubercles. Computation of Coefficient of pressure [Formula: see text] distribution is also done by both numerical and wind tunnel experiments. Analysis of [Formula: see text] distribution allows the identification of critical regions that initiate the adverse pressure gradient and region of flow separation. It is a novel effort to predict the Coefficients of Lift [Formula: see text] and Drag [Formula: see text] concerning the bio-inspired airfoils through [Formula: see text] distribution such that the influence of flow separation and vortex distribution are characterized for the modified and baseline airfoils. Comparison of [Formula: see text], [Formula: see text], and [Formula: see text] between the baseline and modified airfoils reveal the enhanced momentum transfer characteristics of bio-inspired tubercles.
Shameless normalization as a result of media control: The case of Austria
Authors: Wodak Ruth
Published: June 2022

Far-right populist parties instrumentalize the media and intervene into processes of mediatization in significantly different ways, depending on socio-political contexts, their position of power, their role in government or opposition and – related to the latter – their specific access to media. In this paper, I focus on one of the many ways propagandistic tools are employed to control the relevant agenda and information being disseminated by both traditional media and online, in other words ‘message control’. Message control illustrates one of many steps of normalization of far-right agenda. The concept of ‘message control’ emerged from the specific propaganda tool developed by the former Austrian Chancellor Sebastian Kurz and his followers and implies launching and thus controlling select information via weekly press conferences, briefings, personal conversations, back-ground conversations ( Hintergrundgespräche), and text messages, and to financially subsidize only those media that reported favorably about the activities of Kurz’s government. Thus, a new media logic based on favoritism, nepotism, and clientelism was established and normalized. This stands in contrast to Trumpism, which delegitimized all investigative journalism without explicitly attempting to control it. Former US President Donald Trump constitutes rather a prime example of Löwenthal and Guterman’, as he instrumentalized far-right and extreme-right media channels (such as Breitbart or Fox News) and extensively used Twitter to spread systematic disinformation.
A southern refugium for temperate tree species in the Mediterranean mountains of El Port massif (NE Iberia): Charcoal analysis at Cova Del Vidre
Authors: Alcolea Marta , Chabal Lucie , Bosch-Arguilagós Josep , Piqué Raquel
Published: June 2022

This study focuses on the analysis of wood charcoal from Cova del Vidre (Roquetes, Tarragona, Spain). This cave, located at an altitude of 1000 m a.s.l., is a key site for understanding the transition from hunting and gathering to farming in a mountainous region of north-eastern Iberia so far unexplored by archaeobotany. The anthracological study is based on four archaeological levels from the Epipalaeolithic to the Early Neolithic dated between 12.9 and 6.8 kyr cal BP, that is, from the Late Glacial period to the Middle Holocene. During the Younger Dryas, the record is dominated by a little varied spectrum of cryophilous pines ( Pinus tp. sylvestris) and thorny shrubs revealing an open landscape where Prunus may prefigure the spread of temperate taxa. In the Early Holocene, a significant change in temperature and precipitation is evidenced, which promoted successional changes in plant communities, with a decline of pine and the sudden rise of temperate/Mediterranean taxa, such as Prunus and Quercus coccifera/ilex. During the Middle Holocene, other temperate taxa appear, such as Quercus deciduous, Buxus sempervirens and Taxus baccata, with yew finally dominating the anthracological record. The appearance and early development of temperate or Mediterranean species as early as the Younger Dryas and the Early Holocene periods, in a mountain context that had long been favourable for Scots pine, allows us to argue the local existence of a glacial refugium. Differences with the nearby sites in the lowlands demonstrate that altitudinal differences in vegetation were already established in the Holocene. Furthermore, the site helps to define the palaeodistribution of Taxus baccata, Abies alba and Fagus sylvatica in southern Europe.
Dental amalgam fillings and mercury vapor safety limits in American adults
Authors: Geier DA , Geier MR
Published: June 2022

Objective

For more than 150 years, dental amalgam fillings (50% metallic mercury (Hg0) by weight) have been used in American dentistry. The US Food and Drug Administration (FDA) acknowledged that amalgams release Hg vapor that may be harmful to certain patients. This study examined the impact of Hg vapor exposure from amalgams in American adults.

Methods

Amalgam-Hg vapor exposure among 158,274,824 weighted-adult Americans was examined in the 2015–2018 National Health and Nutrition Examination Survey (NHANES). Beta (β)-coefficients were calculated for the correlation between the number of amalgam surfaces and daily micrograms (μg) of urinary Hg and daily μg of Hg vapor exposure from amalgams per kilogram (Kg) bodyweight.

Results

About 91 million (57.8%) adults had ≥1 amalgam surface and about 67 million (42.2%) had no amalgams. A β-coefficient = 0.041 significantly correlated the number of amalgam surfaces to daily amounts of urinary Hg. Differences were observed for gender and racial groups. Daily Hg vapor doses from amalgams were in excess of the most restrictive California’s Environmental Protection Agency (EPA) safety limit for about 86 million (54.3%) adults and in excess of the least restrictive US EPA safety limit among about 16 million (10.4%) adults. The mean allowable number of amalgam surfaces ranged from 1.28 for adult females under the California’s EPA safety limit to 16.23 for adult males under the US EPA safety limit.

Conclusion

Given that American adults are receiving significant, ongoing exposure to Hg vapor from amalgams, careful evaluation of the need to reduce use of amalgams should be considered.
Cognitive Grammar and Readers’ Perceived Sense of Closeness: A Study of Responses to Mary Borden’s ‘Belgium’
Authors: Giovanelli Marcello
Published: June 2022

This article analyses the degree to which readers report a perceived sense of closeness to the events depicted in ‘Belgium’, the opening story of Mary Borden’s The Forbidden Zone. Theoretically, I draw on Ronald Langacker’s Cognitive Grammar, which models language primarily through its notion of construal, an aspect of which claims that - ing forms impose an internal perspective on a scene that results in the interpretative effect of it being ‘close by’. This study tests this idea empirically by utilising a quantitative tool (Likert scale) to elicit two sets of verbal data, which are then analysed qualitatively. My analysis demonstrates that readers respond to the events in the story and articulate the relationship of particular language features to their responses in different – and often surprising – ways. The study is the first in stylistics to empirically test the interpretative effects of verb forms as theorised by Cognitive Grammar and thus contributes new knowledge both by exploring how the landscapes of First World War literature are experienced by readers and analysing how the language of those landscapes may give rise to particular reported effects.
Effect of orientation of CNTs and piezoelectric fibers on the damping performance of multiscale composite plate

Published: June 2022

The present work deals with the study of active constrained layer damping treatment of multiscale carbon nanotube-based hybrid carbon fiber-reinforced composite plates. The distinctive feature of novel multiscale hybrid carbon fiber-reinforced composites is that the wavy/straight carbon nanotubes are distributed uniformly in the matrix phase of hybrid carbon fiber-reinforced composites, and the waviness of carbon nanotubes is considered to be coplanar with two mutually orthogonal planes. Firstly, the effective elastic properties of hybrid carbon fiber-reinforced composites are estimated using the Mori-Tanaka method. The outcomes of the Mori-Tanaka method suggest that the transverse effective elastic properties of hybrid carbon fiber-reinforced composites containing wavy carbon nanotubes are better than those of hybrid carbon fiber-reinforced composites with straight carbon nanotubes. Secondly, a finite element model using the layer-wise first-order shear deformation theory is developed to study the damping performance of hybrid carbon fiber-reinforced composite plates integrated with the active constrained layer damping treatment. The constraining layer of active constrained layer damping treatment is a 1–3 piezoelectric composite layer with vertically/obliquely-oriented piezo-fibers. The piezo-fibers make an angle [Formula: see text] with the vertical plane of a layer coplanar with the xz- or yz-plane. The effect of the orientation of piezo-fibers angle on the control authority of active constrained layer damping treatment patches is investigated. Our results reveal that the performance of multiscale hybrid carbon fiber-reinforced composite plates has improved due to the incorporation of wavy carbon nanotubes, and the orientation angle of piezo-fibers has a major impact on the control authority of active constrained layer damping patches. The proposed multiscale composite with the combination of wavy carbon nanotubes and active constrained layer damping patches can be actively used in the aerospace and transport industries to control the mechanical vibrations of structures.
Emotional Dissonance and Affective Organizational Commitment in Family Firm Top Management Teams
Authors: Hoekx Laura , Lambrechts Frank , Vandekerkhof Pieter , Voordeckers Wim
Published: June 2022

This article studies the impact of emotional dissonance experienced in interactions with the CEO on affective organizational commitment in family firm top management teams. We argue that this relationship will be mediated by the level of satisfaction with the CEO. Additionally, we propose that CEO ownership will have a moderating effect. Using a multiple-respondent dataset of 212 top managers from 45 family firms, we find that emotional dissonance leads to less satisfaction with the CEO, influencing the level of affective organizational commitment. This relationship is even stronger if the CEO has a high degree of ownership power.
Effects of Modularized Workshop Trainings on Youth Clinical Progress in a Public Mental Health System

Published: June 2022

Research suggests that a modular approach to treatment and training may be a promising method for promoting evidence-based practices (EBPs). Furthermore, there is growing evidence that the effects of training on specific technique implementation are affected by therapist and youth factors as well as the type of problem area addressed during training. The current study expanded these findings by examining the extent to which youths’ clinical progress improved as a result of therapists’ attendance at modular workshop trainings. Longitudinal, archival data from community mental health providers ( n = 48) who participated in a series of anxiety and/or disruptive behavior workshops in modular approaches to EBPs for youth were examined using cross-classified multilevel modeling. Results indicated that youths’ month in treatment and therapists’ practice behaviors following their training significantly and positively influenced clinical progress. However, only therapists who attended a disruptive behavior training reported greater rates of improved youth treatment progress. Therapists’ knowledge of the trained techniques was not a significant moderator of outcomes. Results suggest that therapists may require differential training and implementation supports that vary as function of problem area to positively enhance youth outcomes. Limitations and implications for EBP dissemination and implementation are discussed.
Special Educator Burnout and Fidelity in Implementing Behavior Support Plans: A Call to Action
Authors: Garwood Justin D.
Published: June 2022

Special education teachers have one of the most challenging and stressful jobs in public education, which often leads to increased burnout. High levels of burnout have, in turn, been related to lower levels of fidelity of implementation in delivery of evidence-based behavior interventions. The purpose of this position paper is to (a) propose exploration of several potential malleable factors related to burnout of special educators serving students with and at risk for emotional and behavioral disorders, (b) link those suggestions to theoretical frameworks, (c) discuss the relation between burnout and fidelity, and (d) suggest measures that may be used to pursue this research, with the ultimate goal of helping the field discover means of intervention to remediate and prevent burnout.
Content Validation of the Behavioral and Emotional Rating Scale–3rd Edition: Strength-Based Interview
Authors: Pierce Corey D. , Epstein Michael H. , Wood Matthew D.
Published: June 2022

Strength-based assessment has achieved acceptance from educational, mental health, and social service professionals as a means to measuring emotional and behavioral strengths of children. Several standardized, norm-referenced tests have been developed to assess these strengths; however, the primary mode of assessment is via informal interviews of parents and caregivers. In many cases, these interviews lack psychometric support, including basic validity and reliability. The purpose of this study was to document the multistep process used to establish the content validity of a newly developed instrument: Behavioral and Emotional Rating Scale: Strength-Based Interview. Specifically, the results of a survey of 40 U.S. professional mental health staff and educators are described where respondents rated the importance of interview questions to the construct of strength-based assessment. The findings of the survey as well as the 18 items deemed most important are reported. Research limitations, future research, and implications for mental health and educational professionals are discussed.
How Can Digital Mental Health Enhance Psychiatry?

Published: June 2022

The use of digital technologies is constantly growing around the world. The wider-spread adoption of digital technologies and solutions in the daily clinical practice in psychiatry seems to be a question of when, not if. We propose a synthesis of the scientific literature on digital technologies in psychiatry and discuss the main aspects of its possible uses and interests in psychiatry according to three domains of influence that appeared to us: 1) assist and improve current care: digital psychiatry allows for more people to have access to care by simply being more accessible but also by being less stigmatized and more convenient; 2) develop new treatments: digital psychiatry allows for new treatments to be distributed via apps, and practical guidelines can reduce ethical challenges and increase the efficacy of digital tools; and 3) produce scientific and medical knowledge: digital technologies offer larger and more objective data collection, allowing for more detection and prevention of symptoms. Finally, ethical and efficacy issues remain, and some guidelines have been put forth on how to safely use these solutions and prepare for the future.
