Mind, body, and soul: The effects of bodily movement on listeners’ perceptions of choral performances

The purpose of this study was to examine what effect performer’s bodily movement may have on listeners’ (N = 103) perceptions of a choral ensemble performance. A 34-voice choir was audio/video recorded performing two different musical excerpts. Each excerpt was recorded twice, once with movement and once without movement, for a total of four audio/video recordings. Additionally, the audio from each of these recordings was isolated and used as a separate stimuli. Participants were presented each stimuli (movement/non-movement, audio only/audio + video), and asked to rate each for expressivity and style. The factor of audio/video was not found to have consistently significant differences in rating. However, there was a consistent interaction effect between these two stimuli, suggesting that both the visual and auditory differences when using movement conversely effected the listeners’ perception. College major did not prove to be a consistent indicator, but membership in a choral ensemble significantly impacted ratings. Implications may include a greater effect of movement when viewed by the listener than simply what can be perceived in the aural stimuli alone. Suggestions for further research include additional study between choral and instrumental music.
Sensorless interior permanent magnet synchronous motor control with rotational inertia adjustment

Mechanical model is generally required in high dynamic sensorless motor control schemes for zero phase lag estimation of rotor position and speed. However, the rotational inertia uncertainty will cause dynamic estimation errors, eventually resulting in performance deterioration of the sensorless control system. Therefore, this article proposes a high dynamic performance sensorless control strategy with online adjustment of the rotational inertia. Based on a synthetic back electromotive force model, the voltage equation of interior permanent magnet synchronous motor is transformed to that of an equivalent non-salient permanent magnet synchronous motor. Then, an extended nonlinear observer is designed for interior permanent magnet synchronous motor in the stator-fixed coordinate frame, with rotor position, speed and load torque simultaneously estimated. The effect of inaccurate rotational inertia on the estimation of rotor position and speed is investigated, and a novel rotational inertia adjustment approach that employs the gradient descent algorithm is proposed to suppress the dynamic estimation errors. The effectiveness of the proposed control strategy is demonstrated by experimental tests.
Dose-Dependent Impairment of the Immune Response to the Moderna-1273 mRNA Vaccine by Mycophenolate Mofetil in Patients with Rheumatic and Autoimmune Liver Diseases

The purpose of this study was to evaluate the efficacy and safety of the Moderna-1273 mRNA vaccine for SARS-CoV-2 in patients with immune-mediated diseases under different treatments. Anti-trimeric spike protein antibodies were tested in 287 patients with rheumatic or autoimmune diseases (10% receiving mycophenolate mofetil, 15% low-dose glucocorticoids, 21% methotrexate, and 58% biologic/targeted synthetic drugs) at baseline and in 219 (76%) 4 weeks after the second Moderna-1273 mRNA vaccine dose. Family members or caretakers were enrolled as the controls. The neutralizing serum activity against SARS-CoV-2-G614, alpha, and beta variants in vitro and the cytotoxic T cell response to SARS-CoV-2 peptides were determined in a subgroup of patients and controls. Anti-SARS-CoV-2 antibody development, i.e., seroconversion, was observed in 69% of the mycophenolate-treated patients compared to 100% of both the patients taking other treatments and the controls (p < 0.0001). A dose-dependent impairment of the humoral response was observed in the mycophenolate-treated patients. A daily dose of >1 g at vaccination was a significant risk factor for non-seroconversion (ROC AUC 0.89, 95% CI 0.80–98, p < 0.0001). Moreover, in the seroconverted patients, a daily dose of >1 g of mycophenolate was associated with significantly lower anti-SARS-CoV-2 antibody titers, showing slightly reduced neutralizing serum activity but a comparable cytotoxic response compared to other immunosuppressants. In non-seroconverted patients treated with mycophenolate at a daily dose of >1 g, the cytotoxic activity elicited by viral peptides was also impaired. Mycophenolate treatment affects the Moderna-1273 mRNA vaccine immunogenicity in a dose-dependent manner, independent of rheumatological disease.
A Study on the compensation margin on butt welding joint of Large Steel plates during Shipbuilding construction.

This paper examines the characteristics of butt welding joint shrinkage for shipbuilding and marine structures main plate. The shrinkage strain of butt welding joint which is caused by the process of heat input and cooling, results in the difference between dimensions of the actual parent metal and the dimensions of design. This, in turn, leads to poor quality in the production of ship blocks and reworking through period of correction brings about impediment on improvement of productivity. Through experiments on butt welding joint's shrinkage strain on large structures main plate, the deformation of welding residual stress in the form of I, Y, V was obtained. In addition, the results of experiments indicate that there is limited range of shrinkage in the range of 1 ∼ 2 mm in 11t ∼ 21.5t thickness and the effect of heat transfer of weld appears to be limited within 1000 mm based on one side of seam line so there was limited impact of weight of parent metal on the shrinkage. Finally, it has been learned that Shrinkage margin needs to be applied differently based on groove phenomenon in the design phase in order to minimize shrinkage.
A LONGITUDINAL STUDY OF FACTORS AFFECTING MIGRANT SUBJECTIVE WELL-BEING: EMPIRICAL EVIDENCE FROM LATVIAN EMIGRANT SURVEYS

People migrate for a variety of reasons, not only economic ones, but most expect to increase their quality of life and happiness by changing their place of residence. Most research on the integration of Eastern European migrants focuses primarily on their structural integration into the labour market, much less is known about the implications of migration on the general subjective well-being (SWB) of individuals. The terms ‘SWB’ and ‘happiness’ refer to people’s evaluations of their life which can be either cognitive or affective (e.g. Diener, 2009). From a theoretical perspective, migration decision-making can still be encompassed within a utility-maximising framework. Now, however, utility is captured by subjective judgements of satisfaction rather than monetary income. Quantitative data from two waves of a large-scale longitudinal survey of Latvian emigrants (2014 -2019 ) were used to identify the determinants of SWB and explore the impact of different factors (such as changes in family status, employment or health) on changes in life satisfaction over time.
Combining LiDAR Metrics and Sentinel-2 Imagery to Estimate Basal Area and Wood Volume in Complex Forest Environment via Neural Networks

Forest ecosystems play a fundamental role in natural balances and climate mechanisms through their contribution to global carbon storage. Their sustainable management and conservation is crucial in the current context of global warming and biodiversity conservation. To tackle such challenges, earth observation data have been identified as a valuable source of information. While earth observation data constitute an unprecedented opportunity to monitor forest ecosystems, its effective exploitation still poses serious challenges since multimodal information needs to be combined to describe complex natural phenomena. To deal with this particular issue in the context of structure and biophysical variables estimation for forest characterization, we propose a new deep learning-based fusion strategy to combine together high density three-dimensional (3-D) point clouds acquired by airborne laser scanning with high-resolution optical imagery. In order to manage and fully exploit the available multimodal information, we implement a two-branch late fusion deep learning architecture taking advantage of the specificity of each modality. On the one hand, a 2-D CNN branch is devoted to the analysis of Sentinel-2 time series data, and on the other hand, a multilayer perceptron branch is dedicated to the processing of LiDAR-derived information. The performance of our framework is evaluated on two forest variables of interest: total volume and basal area at stand level. The obtained results underline that the availability of multimodal remote sensing data is not a direct synonym of performance improvements but, the way in which they are combined together is of paramount importance.
Mineralogical mapping using EO-1 Hyperion data for iron mine identification

The Tamera open pit mine is located in the Nefza mining district (north-west of Tunisia) where the reddish soil reveals its strong potential for heavy Fe mineralization, along with other metals (Pb, Zn, and Mn). This study explored Iron oxide mineralization in a particular nappe zone using multiscale field visible and near infrared/short waves infrared and EO-1 Hyperion hyperspectral data. Thus, spectral features fittings were conducted on Hyperion data for mineral mapping using scene-extracted endmembers. A first minimum noise fraction algorithm was used to reduce the hyperspectral data ’ s dimensionality, followed by the Pixel Purity Index and n -dimensional visualization to extract the pure pixels (endmembers) from the cluster of pixels in the data cube. Furthermore, 56 soil samples were collected from the test site and spectrally measured using Analytical Spectral Devices FieldSpecHiRes spectrometer, which covers the spectral range between 350 and 2500 nm. All samples were analyzed in the laboratory with x-ray diffraction. Endmember extracted spectra were compared with field measurements before EO-1 Hyperion processing. Mapping results revealed the occurrence of a mineralogy composition consisting particularly of iron oxide minerals (hematite and goethite) and bearing minerals, such as clays (kaolinite), within all samples. © The Authors.

Morphometric analysis of Skiagia-plexus acritarchs from the early Cambrian of North Greenland: toward a meaningful evaluation of phenotypic plasticity

Abstract. — The Cambrian evolutionary radiations are marked by spectacular biotic turnovers and the establishment of increasingly tiered food chains. At the base of these food chains are primary producers, which in the Cambrian fossil record are chiefly represented among organic-walled microfossils. The majority of these microfossil remains have traditionally been attributed to an informal category of incertae sedis called “acritarchs,” based entirely on form taxonomy. Acritarch form taxa have been intensely used for biostratigraphy and in large-scale studies of phytoplankton diversity. However, both prospects have been challenged by cases of taxonomic inconsistencies and oversplitting arising from the large phenotypic plasticity seen among these microfossils. The acritarch form genus Skiagia stands as an ideal case study to explore these taxonomic challenges, because it encompasses a number of form species widely used in lower Cambrian biostratigraphy. Moreover, subtle morphological differences among Skiagia species were suggested to underlie key evolutionary innovations toward complex reproductive strategies. Here we apply a multivariate morphometric approach to investigate the morphological variation of Skiagia-plexus acritarchs using an assemblage sourced from the Buen Formation (Cambrian Series 2, Stages 3–4) of North Greenland. Our analysis showed that the species-level classification of Skiagia discretizes a continuous spectrum of morphologies. While these findings bring important taxonomic and biostratigraphic hurdles to light, the unequal frequency distribution of life cycle stages among Skiagia species suggests that certain elements of phytoplankton paleobiology are nonetheless captured by Skiagia form taxonomy. These results demonstrate the value of using morphometric tools to explore acritarch phenotypic plasticity and its potential ontogenetic and paleoecological drivers in Cambrian ecosystems.
Competition in search markets with naive consumers

We study the interplay between quality provision and consumer search in a search market where ﬁrms may design products of inferior quality to promote them to naive consumers who fail to fully understand product characteristics. We derive an equilibrium in which both superior and inferior quality is offered and show that as search frictions vanish, the share of ﬁrms offering superior goods in the market goes to zero. The presence of inferior products harms sophisticated consumers, as it forces them to search longer to ﬁnd a superior product. We argue that policy interventions that reduce search frictions such as the standardization of price and package formats may harm welfare. In contrast, reducing the number of naive consumers through transparency policies and education campaigns as well as a minimum quality standard can improve welfare.
Analyzing the characteristics of contaminant transport using the Perron-Frobenius operator in indoor building environments

People in the developed world spend the majority of their lives indoors. While inside, people can be exposed to many different gaseous and particulate contaminants. Both short term and long term exposure to these contaminants have a wide range of health related outcomes from mild discomfort to heart disease, cancer, and even death. The purpose of this research is to provide a computational framework for fast predictions of the transport of contaminants, which is used to identify optimal locations for sensors, and finally the framework is utilized to provide performance measures for ventilation system during the design stage. All these applications can be analyzed using the discrete form of the PerronFrobenius operator, also known as Markov matrices. Two different methods are developed for fast and accurate calculations of contaminant transport at large Courant numbers. Once the Markov matrices are calculated, they are used to position sensors where contaminants are likely to collect and are used to quantify mechanical ventilation performance. The methods developed may be used to develop evacuation for people during a release of a toxic gas or airborne infectious disease, execute containment plans of potentially harmful airborne contaminants, and the control of HVAC systems to provide adequate ventilation and clean/fresh air to the occupied space.
Extracurricular Activities In The Broader Personal Development: Reflections From Youth In Public Secondary Schools

This study examined extracurricular activities in the broader personal development: Reflections from Youth in Public Secondary Schools. Specifically, the study examined the contribution of extracurricular in the areas of leadership, sexual reproductive health, and good academic performance in public secondary schools in Muheza and Korogwe districts in the Tanga region, Tanzania. The study was qualitative which adopted the interpretive paradigm. Data were collected through focused group discussions from 160 secondary school students who experienced extracurricular activities in their school environment. Grounded theory methodology was used to analyze the data collected. The study findings revealed that extracurricular contribute to leadership as it builds youth with leadership skills, teach youth to volunteer, and inform youth that leadership is about having agenda. Additionally, the study exposed that extra-curricular activities are important in educating the youth on sexual reproductive health as they learn about their bodies, hygiene at puberty age, being unastonished by the biological changes but also extracurricular help youth to manage risk sexual behavior. With regards to good academic performance, the study revealed that extracurricular are for academic benefits, as it aspires to academic discussion and has minimized students' truancy. The study concludes that Extracurricular influences secondary school youth's development as it exposes them to environments translating into real situations affecting their wellbeing. Through extracurricular students can explore their environment, encouraging innovations and building creativity with very minimal resources. Additionally, extracurricular activities have proved to have a positive behavior outcomes such as academic performance in the school-age stage and occupational status and income in adulthood. The study suggests that the government should translate extracurricular activities from documents to actions and give equal weight to both classroom and non-classroom activities. The extracurricular activities balance the existing gap between soft and hard skills. That extracurricular helps youth to address challenges they face in their daily life. Extracurricular found to be of interest to students because it all connected to people’s character and it is widely applicable to most areas. While hard skills help an individual to enter a job market, soft skills guarantee job opportunities and further career growth.
Participatory Action Research

Participatory Action Research (PAR) models are increasingly used in disciplines such as social sciences and health to actively engage people with lived experiences as co-researchers and act on findings to improve their lives. In recent years, the potential of PAR to yield meaningful benefits via collaborative research activities with people who are multiply marginalized and excluded from dominant forms of knowledge production has gained more recognition. This rise in popularity calls for in-depth discussions about contemporary methodological issues and taken-for-granted principles that can yield tokenistic outcomes and ethical dilemmas. What do genuine participation and research co-production look like when co-researchers are actively involved in data collection, analysis, and sharing? How do we address ethical issues when projects and relationships become problematic and messy? In addition to answering these questions, this book repositions PAR as an intersectional decolonial methodology and an effective tool to disrupt harmful western or Eurocentric research frameworks in favor of approaches such as Indigenous PAR. It outlines how intersectional feminist principles enrich PAR and honor diverse gender expressions to address enduring inequalities rather than reinforce colonial, elitist, and transphobic notions of feminism. The discussion on influencing policymaking using PAR findings points to the importance of effective knowledge translation plans and intersectional feminist policy analysis frameworks. Using reflexive vignettes from diverse participatory researchers, this book provides practical and conceptual insights into the politics of PAR and its potential to yield new possibilities for individual, community, and policy change when participatory approaches are used in collaborative and ethical ways.
Electrophysiological Bases of Torsion and Suction in the Continuous Cardiac Band Model

Objective: Torrent Guasp concept, that postulates that the ventricles are formed by a continuous muscle band, provides the basis for two aspects of left ventricular dynamics: The torsion mechanism and the rapid early diastolic filling by the suction effect. We investigated the electrophysiological basis of this mechanism, by electroanatomical left ventricular endoepicardial mapping (EEM) in five patients, during radiofrequency ablation. Results: The apical loop is activated by a simultaneous depolarization of the distal descending and proximal ascending band segments. At the point of crossing of both bands a radial activation spreads from the descending to the ascending band. From this point, begins a simultaneous and opposing activation of the proximal and distal ascending band. The activation of the distal ascending band segment is the latest. Conclusions: The activation sequence of the continuous band provides an electrophysiological basis for the ventricular torsion and suction mechanism.
Redox Mechanisms of Platelet Activation in Aging

Aging is intrinsically linked with physiologic decline and is a major risk factor for a broad range of diseases. The deleterious effects of advancing age on the vascular system are evidenced by the high incidence and prevalence of cardiovascular disease in the elderly. Reactive oxygen species are critical mediators of normal vascular physiology and have been shown to gradually increase in the vasculature with age. There is a growing appreciation for the complexity of oxidant and antioxidant systems at the cellular and molecular levels, and accumulating evidence indicates a causal association between oxidative stress and age-related vascular disease. Herein, we review the current understanding of mechanistic links between oxidative stress and thrombotic vascular disease and the changes that occur with aging. While several vascular cells are key contributors, we focus on oxidative changes that occur in platelets and their mediation in disease progression. Additionally, we discuss the impact of comorbid conditions (i.e., diabetes, atherosclerosis, obesity, cancer, etc.) that have been associated with platelet redox dysregulation and vascular disease pathogenesis. As we continue to unravel the fundamental redox mechanisms of the vascular system, we will be able to develop more targeted therapeutic strategies for the prevention and management of age-associated vascular disease.
Validation of Indonesian Version of Offence-Related Feelings of Guilt and Shame: A Rasch Model Analysis

This study aims to conduct an adaptation and validation of the Offence-Related Feelings of Shame and Guilt Scale (ORSGS) in the Indonesian language. ORGS was translated into the Indonesian language using a forward translation method by a bilingual psychology expert. Five hundred ten male prisoners from three correctional institutions in Indonesia were recruited and completed the Indonesian version of ORSGS in paper-and-pencil. A Rasch model approach was applied to evaluate the psychometric properties and validity of the adapted scale. The results showed that the Indonesian version of ORSGS had moderate Cronbach’s Alpha reliability (α= .65) and excellent item reliability (.99). Item logit ranged from -1.08 to . 72 with a separation value of 8.79, showing that items were grouped into 12 groups. The unidimensionality was found as acceptable/ moderate by 30.4% total variance explained from Principal Component Analysis but still needs further confirmatory analysis. Item 1 and 2 were found to be misfit and need to be evaluated. According to the Rasch model result, it can be concluded that the Indonesian version of ORSGS was valid (10 out of 12 items were fit) and reliable (Item reliability: .99) to be used in the prisoner population. However, further investigation about its multidimensionality and criterion validity still needs to be conducted
