P-06 Spirituality and Life Skills and Their Relationship with Reasons for attending Four Selected Adventist Universities in Asia
The purposes of this study are: (a) to report on the reasons for attending four Adventist universities in Asia; (b) to describe the universities’ perceived influence on student development of spirituality and life skills; and (c) to determine if reasons for attending and perceived influence on development of religiosity and life skills may be related. Survey research methodology was the design used to collect data using printed questionnaires. We designed the questionnaire to elicit information on reasons for attending the universities, engagement in curricular and extra-curricular activities, and the extent to which the university influenced student development of life skills, spirituality and altruism. One thousand nine hundred and ninety-eight (1,998) students participated in this study. Approximately 50% selected these universities for their spiritual atmosphere and spiritual values. Students generally agree that the universities have positively influenced the development of their life skills (M=4.05, SD=0.59) and spirituality (M=4.15, SD=0.69). There are no significant class status or gender differences on these variables. There are some variation among the universities but the effect size is small (η2≤.05). Approximately 15% of the variance on the linear combination of the development of religiosity and life skills are associated with the reasons for selecting Adventist universities
A roadmap to integrate astrocytes into Systems Neuroscience.
Systems neuroscience is still mainly a neuronal field, despite the plethora of evidence supporting the fact that astrocytes modulate local neural circuits, networks, and complex behaviors. In this article, we sought to identify which types of studies are necessary to establish whether astrocytes, beyond their well-documented homeostatic and metabolic functions, perform computations implementing mathematical algorithms that sub-serve coding and higher-brain functions. First, we reviewed Systems-like studies that include astrocytes in order to identify computational operations that these cells may perform, using Ca2+ transients as their encoding language. The analysis suggests that astrocytes may carry out canonical computations in a time scale of subseconds to seconds in sensory processing, neuromodulation, brain state, memory formation, fear, and complex homeostatic reflexes. Next, we propose a list of actions to gain insight into the outstanding question of which variables are encoded by such computations. The application of statistical analyses based on machine learning, such as dimensionality reduction and decoding in the context of complex behaviors, combined with connectomics of astrocyte-neuronal circuits, is, in our view, fundamental undertakings. We also discuss technical and analytical approaches to study neuronal and astrocytic populations simultaneously, and the inclusion of astrocytes in advanced modeling of neural circuits, as well as in theories currently under exploration such as predictive coding and energy-efficient coding. Clarifying the relationship between astrocytic Ca2+ and brain coding may represent a leap forward toward novel approaches in the study of astrocytes in health and disease
A Brief Report: Preliminary Findings for Pathways to Resilience among Critical Incident Stress Management Responders
Previous research by Burnett, Pichot, and Bailey (2019) found support for several innate well-being and behavioral action variables that contribute to Everly’s Psychological Body Armor’s (PBA) two unique interacting human protective pathways (proactive and reactive resilience) among a non-disaster mental health response population. However, research is limited regarding the unique proactive and reactive pathway variables that contribute to resilience capacity among trained disaster mental health responders. Participants (N = 63) were novice and experienced disaster mental health responders who attended a Critical Incident Stress Management (CISM) training conference in Michigan that completed the same 14 measures used in the original Burnett, Pichot, and Bailey study. Similar to the Burnett, Pichot, and Bailey study, hierarchical regression analyses revealed that for the proactive pathway, self-acceptance and subjective happiness were significant unique predictors for resilience capacity, while psychological distress and perceived stress were significant unique predictors for the reactive pathway. A qualitative comparative analysis (QCA) found that all but one of the cases met the observation criteria for having high resilience. However, when the dataset for this study was combined with the original study (NCombined = 265), QCA revealed that overall; having professional CISM training contributed more to strong resilience making the proactive pathway irrelevant
Empowering Frontline Trauma Responders: Keys to Resilience
CISM teams and responders play a vital role in helping those who have been affected by traumatic to successfully manage their stress reactions. It is important that individual CISM responders, along with teams, take time to incorporate an active resilience-based approach which makes use of well-being traits
Pressure dependence of Raman modes in double wall carbon nanotubes filled with α-Fe.
The preparation of highly anisotropic one-dimensional (1D) structures confined into carbon nanotubes (CNTs) in general is a key objective in CNTs research. In this work, the capillary effect was used to fill double wall carbon nanotubes with iron. The samples are characterized by Mössbauer and Raman spectroscopy, transmission electron microscopy, scanning area electron diffraction, and magnetization. In order to investigate their structural stability and compare it with that of single wall carbon nanotubes (SWNTs), elucidating the differences induced by the inner-outer tube interaction, unpolarized Raman spectra of tangential modes of double wall carbon nanotubes (DWNTs) filled with 1D nanocrystallin α-Fe excited with 514 nm were studied at room temperature and elevated pressure. Up to 16 GPa we find a pressure coefficient for the internal tube of 4.3 cm−1 GPa−1 and for the external tube of 5.5 cm−1 GPa−1. In addition, the tangential band of the external and internal tubes broadens and decreases in amplitude. All findings lead to the conclusion that the outer tube acts as a protection shield for the inner tubes (at least up 16 GPa). Structural phase transitions were not observed in this range of pressure
A new access control unit for GANIL and SPIRAL 2
International audienceFor the GANIL safety revaluation and the new project of accelerator SPIRAL 2, it was decided to replace theexisting access control system for radiological controlled areas. These areas are all cyclotron rooms and experimental areas. The existing system is centralized around VME cards. Updating is becoming very problematic. The new UGA (access control unit) will becomposed of a pair of PLC to ensure the safety of each room. It will be supplemented by a system UGB (radiological control unit) that will assure the radiological monitoring of the area concerned

Correlation of properties with preferred orientation in coagulated and stretch-aligned single-wall carbon nanotubes
We report structure-property correlations in single wall carbon nanotube (SWNT) fibers, among electrical, thermal and chemical parameters with respect to stretch-induced preferential SWNT alignment along the fiber axis. Purified HiPco tubes are dispersed with the aid of an anionic surfactant and coagulated in the co-flowing stream of an adsorbing polymer. The fibers are then dried, rewetted under tensile load and redried to improve the alignment. Complete removal of the polymer was assured by annealing in hydrogen at 1000oC. The degree of alignment was determined by x-ray scattering from individual fibers using a 2-dimensional detector. The half width at half maximum (HWHM) describing the axially symmetric distribution of SWNT axes decreases linearly from 27.5o in the initial extruded fiber to 14.5o after stretching by 80%. The electrical resistivity ρ at 300 K decreases overall by a factor ~4 with stretching, for both as-spun composite and polymer-free annealed fibers. However, the temperature dependence ρ(T) is markedly different for the two, implying different electron transport mechanisms with and without the polymer. Thermal conductivity also improves with increasing alignment, while the absolute values are limited by the disordered network of finite length tubes and bundles. Comparisons are made with results from similar fibers spun from oleum, and with magnetically aligned buckypapers
CREB Regulates Distinct Adaptive Transcriptional Programs in Astrocytes and Neurons
The cyclic AMP response element binding protein (CREB) is a primary hub of a activity-driven genetic programs in neurons controlling plasticity, neurogenesis and survival. By contrast, the gene networks coordinated by CREB in astrocytes are Unknown despite the fact that the astrocytic CREB is a also activity-driven and neuroprotective. Herein we identified the transcriptional programs regulated by CREB in astrocytes as compared to neurons using, as study materials, transcriptome databases of astrocyte exposed to weII-known activators of CREB-dependent transcription as well as publidy available transcriptomes of neuronal cultures. Functional CREB signatures were extracted from the transcriptomes using Gene Ontology, adult-brain gene lists generated by Translating Ribosome Affinity Purification (TRAP) and CREB-target gene repositories. We found minimal overlap between CREB signatures in astrocytes and neurons. In astrocytes, the top triad of functions regulated by CREB consists of'Gene expression', 'Mitochondria', and 'Signa Iling', while in neurons it is 'Neurotransmission', 'Signalling' and 'Gene expression', the latter being represented by different genes from those in astrocytes. The newly gene rated data bases Will provide a tool to explore novel means whereby CREB impinges on brain functions requiring adaptive, long-lasting changes by coordinating transcriptionaI cascades in astrocytes
Creative Individuals are Social Risk-takers: Relationships between Creativity, Social Risk-Taking and Fear of Negative Evaluations
Abstract If the importance of social psychological factors in creativity has been widely emphasized, research across the social sciences mainly focused on identifying contextual factors that increase or decrease individuals’ creative behaviors. Few studies have investigated the relationships between creativity and individual characteristics related to interpersonal and social interactions. The present contribution aimed to consider such characteristics, namely social risk-taking (i.e., willingness to challenge norms) and fear of negative evaluation (i.e., apprehension about receiving negative judgments of others). Two correlational studies were therefore implemented in order to clarify previous research suggesting that creativity would be positively associated with social risk-taking and to extend them by testing potential associations between creativity and fear of negative evaluation. Using self-ratings of creativity, but also creative self-beliefs and creative achievement, we hypothesized that creativity would correlate positively with social risk likelihood and negatively with fear of negative evaluation. As predicted, and replicating previous results, all our measures of creativity correlated positively with social risk-taking. Our results also consistently highlighted a negative association between beliefs in one’s creative capacities (creative self-efficacy) and one’s level of fear of negative evaluation. These findings corroborate the idea according to which creative individuals would be (social) risk-takers. In addition, individuals who are confident in their ability to generate creative productions would be less afraid of negative judgments from others. Several perspectives are proposed, in particular in terms of the intervention designed in order to enhance individuals’ creativity.</jats:p
