title: The Triad Trial: Online Education for Coaches on the Prevention of the Female Athlete Triad
Creators: name: Ostler, Megan Jane
Publisher: name: Utah State University
Year: 2014

description: High school coaches play a huge role in establishing a healthy environment for their athletes and often students. The coach‐athlete relationship has proven to be a strong and useful bond in prevention of adverse behaviors of athletes or in prevention of health problems such as concussions. The female athlete triad (triad) is a common health problem among female athletes. Many high school coaches are unaware of the triad or the serious health and performance consequences for their athletes. The triad is a syndrome marked by 3 interrelated adverse effects: decreased energy availability, menstrual dysfunction, and decreased bone mineral density.
The Purpose of this study was to develop an online educational resource aimed at educating coaches about the triad. After the online education materials were created and reviewed by small panel groups, the materials were launched online and available to the public with the aim to target high school coaches. We collected online surveys from 90 participants including coaches and parents of high school female athletes and found a lack of knowledge, attitudes, and confidence in preventing the triad. By educating coaches and providing the tools for prevention, we hypothesize that coaches can play a large role in the prevention of the triad among high school athletes and help to keep our student athletes healthy and performing well in school and sports.

description: We present a model of dark matter in a warped extra dimension in which the dark sector mass scales are naturally generated without supersymmetry. The dark force, responsible for dark matter annihilating predominantly into leptons, is mediated by dark photons that naturally obtain a mass in the GeV range via a dilaton coupling. As well as solving the gauge hierarchy problem, our model predicts dark matter in the TeV range, including naturally tiny mass splittings between pseudo-Dirac states. By the AdS/CFT correspondence both the dark photon and dark matter are interpreted as composite states of the strongly-coupled dual 4d theory. Thus, in our model the dark sector emerges at the TeV scale from the dynamics of a new strong force.

description: A hallmark of Parkinson’s disease is the formation of large protein-rich aggregates in neurons, where α-synuclein is the most abundant protein. A standard approach to visualize aggregation is to fluorescently label the proteins of interest. Then, highly fluorescent regions are assumed to contain aggregated proteins. However, fluorescence brightness alone cannot discriminate micrometer-sized regions with high expression of non-aggregated proteins from regions where the proteins are aggregated on the molecular scale. Here, we demonstrate that 2-dimensional polarization imaging can discriminate between preformed non-aggregated and aggregated forms of α-synuclein, and detect increased aggregation in brain tissues of transgenic mice. This imaging method assesses homo-FRET between labels by measuring fluorescence polarization in excitation and emission simultaneously, which translates into higher contrast than fluorescence anisotropy imaging. Exploring earlier aggregation states of α-synuclein using such technically simple imaging method could lead to crucial improvements in our understanding of α-synuclein-mediated pathology in Parkinson’s Disease.

description: The proton spin puzzle has challenged our understanding of QCD for the last 20 years. New measurements of polarized glue, valence and sea quark polarization, including strange quark polarization, are available. What is new and exciting in the data, and what might this tell us about the structure of the proton ? The proton spin puzzle seems to be telling us about the interplay of valence quarks with the complex vacuum structure of QCD.

title: Nitrite Reactions in Soil
Creators: name: Reuss, John Otto
Publisher: name: Utah State University
Year: 1963

description: Losses of soil nitrogen that cannot be attributed to leaching or crop removal have been observed in many field experiments. Several mechanisms have been proposed to account for these losses.
Perhaps the best known mechanism involves the process of microbial denitrification. Undoubtedly this process plays a major role in nitrogen loss but it does not seem to adequately account for many of the losses observed. A thorough understanding of other possible loss pathways has tremendous agricultural implications as well as being of interest from a purely scientific standpoint.
It has long been accepted that nitrite is an intermediate in the biological oxidation of ammonium to nitrate. Because of the high reactivity of nitrous acid and the nitrite ion many investigators have proposed pathways involving them. Considering the diversity of possible reactions and products involving nitrite it is not surprising that numerous contradictions are found in the literature on this subject.
The work reported here was an attempt to clarify the role of some of these pathways in the destruction of the nitrite ion in acid soils. The availability of a gas chromatograph and incubation equipment made the study feasible from a technical standpoint.
Most of the data reported here were collected by the author in the late summer of 1961, using techniques developed over the previous year. Some data re included that were collected by Dr. Keith Justice in the summer of 1962 using these same methods.

description: We study dynamical moduli stabilization driven by gaugino condensation in supergravity. In the presence of background radiation, there exists a region of initial conditions leading to successful stabilization. We point out that most of the allowed region corresponds to initial Hubble rate H close to the scale of condensation Λ, which is the natural cutoff of the effective theory. We first show that including the condensate dynamics sets a strong bound on the initial conditions. We then find that (complete) decoupling of the condensate happens at H about two orders of magnitude below Λ. This bound implies that in the usual scenario with the condensate integrated out, only the vicinity of the minimum leads to stabilization. Finally, we discuss the effects of thermal corrections.

description: IPSec is a protocol that allows to make secure connections between branch offices and allows secure VPN accesses. However, the efforts to improve IPSec are still under way; one aspect of this improvement is to take Quality of Service (QoS) requirements into account. QoS is the ability of the network to provide a service at an assured service level while optimizing the global usage of network resources. The QoS level that a flow receives depends on a six-bit identifier in the IP header; the so-called Differentiated Services code point (DSCP). Basically, Multi-Field classifiers classify a packet by inspecting IP/TCP headers, to decide how the packet should be processed. The current IPSec standard does hardly offer any guidance to do this, because the existing IPSec ESP security protocol hides much of this information in its encrypted payloads, preventing network control devices such as routers and switches from utilizing this information in performing classification appropriately. To solve this problem, we propose a QoS-friendly Encapsulated Security Payload (Q-ESP) as a new IPSec security protocol that provides both security and QoS supports. We also present our NetBSD kernel-based implementation as well as our evaluation results of Q-ESP.

description: Théâtre du Cristal is a theatre company composed of 15 actors with disabilities and other artists with and without disabilities. The company was founded thanks to a partnership with the employment promotion agency (ESAT: Établissement et service d’aide par le travail) of Cormeilles en Parisis named “La Montagne.” The theatre group also offers training for the sensitisation of handicaps in the cultural and artistic sectors. Furthermore, they produce and perform plays and cultural events for the wider public, schools, and medico-social organizations. Théâtre du Cristal also cooperates with HAARP (Handicap Autisme Associations Réunies du Parisis), an umbrella organization for handicap and/or autism associations in Parisis.
The company was founded in 1989, and its ensemble performs all over France and Europe. The actors with disabilities perform at Théatre du Cristal’s productions or participate in other castings and productions (theatre and cinema/ television).
Olivier Couder, the group's creative director, has staged more than 20 plays and performances and has written many articles on the issue of handicaps in the performing arts.
In addition, the company cooperates and co-produces with further artists such as Philippe Adrien and “la compagnie du troisième œil,” Olivier Brunhes, Dominique Houdart, Eric Morin Racine. They cooperate on essays for the journal “La vie comme un journal,” which they publish at non-regular intervals.
Moreover, Théâtre du Cristal offers weekly, inclusive theater workshops for people with and without disabilities. The workshops are organized by Patricia Zehme, who has been working with Théâtre du Cristal for a long time. The regional council of Ile de France finances them. The workshops aim to give people with disabilities a better chance of pursuing their acting and theatre interests.
The latest play of Théâtre du Cristal has the working title Variation singulière (2021) and is still a work in progress. It is based on the texts of Philippe Minyana and Olivier Couder. The actors are on stage without a script, so they must improvise. After some hesitation, Louis offers to share and reenact an important moment of his life. Together, the actors help Louis to understand his paradoxical feelings of isolation and retreat. Also, because of this reenactment, Louis has to face his feelings of enormous fatigue and emptiness.
In addition, there are currently three further plays that are performed: Loin du ciel (first run in 2018), Cristal pop, le bal poétique et populaire (first run in 2017) und Cabaret des frissons garantis (first run in 2015).

description: Retrievability measures the influence a retrieval system has on the access to information in a given collection of items. This measure can help in making an evaluation of the search system based on which insights can be drawn. In this paper, we investigate the retrievability in an integrated search system consisting of items from various categories, particularly focussing on datasets, publications \ijdl{and variables} in a real-life Digital Library (DL). The traditional metrics, that is, the Lorenz curve and Gini coefficient, are employed to visualize the diversity in retrievability scores of the \ijdl{three} retrievable document types (specifically datasets, publications, and variables). Our results show a significant popularity bias with certain items being retrieved more often than others. Particularly, it has been shown that certain datasets are more likely to be retrieved than other datasets in the same category. In contrast, the retrievability scores of items from the variable or publication category are more evenly distributed. We have observed that the distribution of document retrievability is more diverse for datasets as compared to publications and variables.

description: The ac nonlinear dielectric response $χ_3(ω,T)$ of glycerol was measured close to its glass transition temperature $T_g$ to investigate the prediction that supercooled liquids respond in an increasingly non-linear way as the dynamics slows down (as spin-glasses do). We find that $χ_3(ω,T)$ indeed displays several non trivial features. It is peaked as a function of the frequency $ω$ and obeys scaling as a function of $ωτ(T)$, with $τ(T)$ the relaxation time of the liquid. The height of the peak, proportional to the number of dynamically correlated molecules $N_{corr}(T)$, increases as the system becomes glassy, and $χ_3$ decays as a power-law of $ω$ over several decades beyond the peak. These findings confirm the collective nature of the glassy dynamics and provide the first direct estimate of the $T$ dependence of $N_{corr}$.

description: Implementing a positive correlation between the natural frequencies of nodes and their connectivity on a single star graph leads to a pronounced explosive transition to synchronization, additionally presenting hysteresis behavior. From the viewpoint of network connectivity, a star has been considered as a building motif to generate a big graph by graph operations. On the other hand, we propose to construct complex synchronization dynamics by applying the Cartesian product of two Kuramoto models on two star networks. On the product model, the lower dimensional equations describing the ensemble dynamics in terms of collective order parameters are fully solved by the Watanabe-Strogatz method. Different graph parameter choices lead to three different interacting scenarios of the hysteresis areas of two individual factor graphs, which further change the basins of attraction of multiple fixed points. Furthermore, we obtain coupling regimes where cluster synchronization states are often present on the product graph and the number of clusters is fully controlled. More specifically, oscillators on one star graph are synchronized while those on the other star are not synchronized, which induces clustered state on the product model. The numerical results agree perfectly with the theoretic predictions. © 2019 The Author(s).

description: Compagnie Création Ephémère is a professional theatre company founded in 1986 and run by the ACT 12 association. This association consists of its members and the administrative board who represent Cie Création Ephémère’s different activities.
The creative director, Phillipe Flahaut, discovered theatre work with people with mental disabilities in 1980 at the Lille Opera (l’Opéra de Lille). After having worked with L’Oiseau Mouche (Roubaix), he founded his own company at Millau (Aveyron). In 1990, Flahaut started the subproject “Création Ephémère,” which is directed to actors with disabilities. Initially, they produced five performances. Since 1991, Flahaut’s project operates as the Centre d’Art Dramatique pour comédiens différents (Center for dramatic arts for “different” actors or short: C.A.D).
The C.A.D is a theatre school for people with disabilities at the heart of the theatre company Cie Création Ephémère. It has been officially inaugurated in 1994 by the Ministry of Culture. The C.A.D. offers internships in the performing arts or for social workers who work with people with disabilities.
The company Cie Création Ephémère often cooperates with contemporary playwrights like Eugène Durif, Michel Genniaux et Filip Forgeau on various national and international projects.
La Fabrick is where Cie Création Ephémère’s plays are produced and where the actors practice. It is a meeting place for local artists and has a bar where the association members can hold their meetings and small performances can take place.
Compagnie creation Ephémère dedicated a part of their productions to young audiences such as children and teenagers. In 2013, they organized the first edition of the youth festival “La Fabrick des Z’enfants.” Also, the company does street work by creating spontaneous street performances.
The company loves Molière, Shakespeare, Tadeusz Kantor, Antonin Artaud, Peter Brook, Samuel Beckett, and absurd theatre. Its productions are contemporary and critically reflect society.

Processing the large amount of multiplex astronomical data is technically challenging, and fully automated technologies based on machine learning and artificial intelligence are urgently needed. Maximizing scientific returns from the big data requires community-wide efforts. We summarize recent progress in machine learning applications in observational cosmology. We also address crucial issues in high-performance computing that are needed for the data processing and statistical analysis.

description: The claims that the GSI time anomaly is due to the mixing of neutrinos in the final state of the observed electron-capture decays of hydrogen-like heavy ions are refuted with the help of an analogy with a double-slit experiment. It is a consequence of causality. It is shown that the GSI time anomaly may be caused by quantum beats due to the existence of two coherent energy levels of the decaying ion with an extremely small energy splitting (about $6\times10^{-16} \text{eV}$) and relative probabilities having a ratio of about 1/99.

title: Social Communication for Students with Autism: Effects of Multiple Scripts on Conversational Exchanges Within Social Dialogue
Creators: name: Christensen, Angela M.
Publisher: name: Utah State University
Year: 2014

description: Students with autism spectrum disorder (ASD) often experience difficulty in initiating and maintaining social dialogue in multiple settings. This study examined the effects of training multiple social scripts, used in sequence, on the number of conversational exchanges within a social dialogue in four male participants with ASD. A multiple baseline design was used across participants to determine if there was an increase in the number of conversational exchanges within a social dialogue after training. In training sessions, participants learned the scripted conversations and used them to engage in social dialogue. During training sessions, scripts were completely faded for three of four participants. However, none of the participants demonstrated an increase in the number of conversational exchanges during the generalization condition in naturalistic settings. This failure to increase in the number of conversational exchanges in generalization settings could possibly be attributed to one or more of the following: a lack of a discriminative stimulus to cue the use of the script, too many words in the scripts, lack of training on more simple scripts first, and a lack of adequate time to facilitate generalization.
Hydrogen-triggered X-ray Bursts from SAX J1808.4-3658? The Onset of Nuclear Burning

description: We present a study of weak, thermonuclear X-ray bursts from the accreting millisecond X-ray pulsar SAX J1808.4-3658. We focus on a burst observed with the Neutron Star Interior Composition Explorer on 2019 August 9, and describe a similar burst observed with the Rossi X-ray Timing Explorer in 2005 June. These bursts occurred soon after outburst onset, $2.9$ and $1.1$ days, after the first indications of fresh accretion. We measure peak burst bolometric fluxes of $6.98 \pm 0.50 \times 10^{-9}$ and $1.54 \pm 0.10 \times 10^{-8}$ erg cm$^{-2}$ s$^{-1}$, respectively, which are factors of $\approx 30$ and $15$ less than the peak flux of the brightest, helium-powered bursts observed from this source. From spectral modeling we estimate accretion rates and accreted columns at the time of each burst. For the 2019 burst we estimate an accretion rate of $\dot M \approx 1.4-1.6 \times 10^{-10}$ $M_{\odot}$ yr$^{-1}$, and a column in the range $3.9-5.1 \times 10^7$ g cm$^{-2}$. For the 2005 event the accretion rate was similar, but the accreted column was half of that estimated for the 2019 burst. The low accretion rates, modest columns, and evidence for a cool neutron star in quiescence, suggest these bursts are triggered by thermally unstable CNO cycle hydrogen-burning. The post-burst flux level in the 2019 event appears offset from the pre-burst level by an amount consistent with quasi-stable hydrogen-burning due to the temperature-insensitive, hot-CNO cycle, further suggesting hydrogen-burning as the primary fuel source. This provides strong observational evidence for hydrogen-triggered bursts. We discuss our results in the context of previous theoretical modeling.

description: For a finite set $\cal F$ of polynomials over fixed finite prime field of size $p$ containing all polynomials $x^2 - x$ a Nullstellensatz proof of the unsolvability of the system $$
 f = 0\ ,\ \mbox{ all } f \in {\cal F} $$ in the field is a linear combination $\sum_{f \in {\cal F}} \ h_f \cdot f$ that equals to $1$ in the ring of polynomails. The measure of complexity of such a proof is its degree: $\max_f deg(h_f f)$.
 We study the problem to establish degree lower bounds for some {\em extended} NS proof systems: these systems prove the unsolvability of $\cal F$ by proving the unsolvability of a bigger set ${\cal F}\cup {\cal E}$, where set $\cal E$ may use new variables $r$ and contains all polynomials $r^p - r$, and satisfies the following soundness condition: -- - Any $0,1$-assignment $\overline a$ to variables $\overline x$ can be appended by an assignment $\overline b$ to variables $\overline r$ such that for all $g \in {\cal E}$ it holds that $g(\overline a, \overline b) = 0$.
 We define a notion of pseudo-solutions of $\cal F$ and prove that the existence of pseudo-solutions with suitable parameters implies lower bounds for two extended NS proof systems ENS and UENS defined in Buss et al. (1996/97). Further we give a combinatorial example of $\cal F$ and candidate pseudo-solutions based on the pigeonhole principle.

description: The effect of semantic satiation of the mediator on A-C learning was investigated in the A-B, B-C, A-C mediation paradigm. The possibility of evaluating the "pseudomediation" proposal is discussed. Two experiments were conducted, both yielding the same results: mediated pairs were learned more easily than non-mediated pairs, and satiation did not appear to have any effect. The "pseudomediation" hypothesis was not tested, and several explanations are offered for the apparent failure of satiation.
Culture shock and moral panic. An analysis of three mainstream Australian newspapers' response to the Bali bombings in October 2002 and the arrest of smiling Amrozi on November 2002
Creators: name: Lulitanond, V
Publisher: name: University Of Tasmania
Year: 2023

description: On the night of 12 October 2002, two bombs exploded in Bali, killing more than 200 people. The first bomb exploded in Paddy's bar, a well known Irish pub in Kuta and was followed by a bigger explosion less than a minute later at the Sari Club. Both were popular venues for Australian tourists. 88 Australians were killed and 196 were injured. The 'Bali bombing', as it came to be known in the media, became a tragedy for all Australians. The Australian media reported this tragedy by covering the stories of victims, the investigation into the bombing, political negotiations between the Indonesian and Australian governments and the capture of some of those allegedly responsible, including the man dubbed 'smiling Amrozi' by the media. This thesis will examine the way three mainstream Australian newspapers reported on the Bali bombing. The three publications, The Australian, The Sydney Morning Herald and The Australian Financial Review were chosen. The analysis will concentrate on the first seven days of coverage of the Bali bombing and the first four days of coverage after the interrogation of Amrozi. This thesis will focus on five different topics: Australian pain, 'Australia owns Bali', Indonesian pain, 'smiling Amrozi' and the way the three selected Australian newspapers reported on Islam. The coverage of the Bali bombing during the first week after the blast emphasised Australian pain and devastation. The press concentrated on the idea that the Bali bombing was an Australian tragedy and implied a sense of ownership over Bali. Bali had been one of Australia's most popular tourist destinations for decades, and after the event, the press reported that 'Terror hits home', and that Australians had lost their paradise. The focus of reporting was on the Australians affected and little room was left for the Indonesians who, especially the Balinese, also lost people in the bombing. The bombing was an economic disaster for the Balinese who lost a large part of their tourist industry, Bali's main income. The coverage, particularly the reporting of the arrest of Amrozi and his reaction, revealed a cultural divide between Australia and Indonesia. Amrozi' s smiling created confusion and anger throughout the Australian community. Confusion also occurred during the reporting of the Bali bombing, with some members of the Australian Muslim community being mistreated by Australians who wrongly believed that Islam has an inherent connection to terrorism.

description: High purity germanium (HPGe) detectors are ubiquitous in nuclear physics experiments and are also used in numerous low radioactive background detectors. The effect of the position of $^{60}$Co and $^{137}$Cs point sources on the shape of spectra were studied with Monte Carlo and HPGe detector measurements. We briefly confirm previous work on the position dependence of relative heights of peaks. Spectra taken with the radiation sources placed at locations around the detector were then compared using the Kolmogorov-Smirnov (K-S) goodness-of-fit test. We demonstrate that with this method the Compton continuum spectral shape has good sensitivity to the radial location of a point-source, but poor angular resolution. We conclude with a study of the position reconstruction accuracy as a function of the number of counts from the source.
title: Studies in Iron Chlorosis of Leaves

description: Normal healthy growth and development of plants is controlled by certain factors known as factors of plant growth. They are soil, climate, and plant inheritance. The soil contains many nutrient elements needed by plants both in macro and micro quantities. Iron is one of the essential elements required by plants in small amounts.
When plants are starving for any of the essential nutrients, characteristic symptoms usually appear as certain abnormalities, discoloration and deformation of leaves, fruits, and other parts. The deficiency symptoms, though not easily recognizable in some cases at the beginning, are quite apparent in advanced stages of plant growth.
The characteristic symptom of iron deficiency in plant nutrition is chlorosis. Chlorosis is a general term which denotes a lack of chlorophyll in leaves and replacement of the normal green color either wholly or in part by yellow color. In most cases the chlorosis is characterized by a distribution of the yellow color throughout the green in patterns. The more specific term, iron chlorosis, refers to chlorosis due to iron deficiency in the plant and which can be alleviated by providing the plant with suitable iron compounds.

A recent work [Science 375, 418 (2022)] made a remarkable breakthrough in the sign problem by pointing out that the sign can be used to probe phase transition. In this work, we proposed a general argument based on the definition of the sign that is related to the difference in free energy between the original and reference systems to clarify that the sign problem and phase transition cannot always be strictly related. The sign can exactly probe phase transition only if the free energy in the reference system is flat under variable parameters, which is almost impossible to design. Generally speaking, the conclusion that the sign can probe phase transition is survivorship bias without universality. To solve this problem, we define a modified sign that excludes the influence of the reference system, which can probe the phase transition strictly. The work gives an unbiased solution for detecting phase transition by the new modified sign.

description: We study the relation between nitrogen and oxygen abundances as a function of metallicity for a sample of emission-line objects for which a direct measurement of the metallicity has been possible. This sample is representative of the very different conditions in ionization and chemical enrichement that we can find in the Universe. We first construct the N/O vs. O/H diagram and we discuss its large dispersion at all metallicity regimes. Using the same sample and a large grid of photoionization models covering very different values of the N/O ratio, we then study the most widely used strong-line calibrators of metallicity based on [NII] emission lines, such as N2 and O3N2. We demonstrate that these parameters underestimate the metallicity at low N/O ratios and viceversa. We investigate also the effect of the N/O ratio on different diagnostic diagrams used to discriminate narrow-line AGNs from star forming regions, such as the [OIII]/Hbeta vs. [NII}]/Halpha, and we show that a large fraction of the galaxies catalogued as composite in this diagram can be, in fact, star forming galaxies with a high value of the N/O ratio. Finally, using strong-line methods sensitive to the N/O abundance ratio, like N2O2 and N2S2, we investigate the relation between this ratio and the stellar mass for the galaxies of the SDSS. We find, as in the case of the mass-metallicity relation, a correlation between these two quantities and a flattening of the relation for the most massive galaxies, which could be a consequence of the enhancement of the dispersion of N/O in the high metallicity regime.

description: We investigated a flat multidimensional cosmological model in Gauss-Bonnet gravity in presence of a matter in form of perfect fluid. We found analytically new stationary regimes (these results are valid for arbitrary number of spatial dimensions) and studied their stability by means of numerical recipes in 4+1-dimensional case. In the vicinity of the stationary regime we discovered numerically another non-singular regime which appears to be periodical. Finally, we demonstrated that the presence of matter in form of a perfect fluid lifts some constraints on the dynamics of the 4+1-dimensional model which have been found earlier.

description: We show that the quantum teleportation protocol is a powerful tool to study quantum phase transitions (QPTs) at finite temperatures. We consider a pair of spins from an infinite spin-1/2 chain (XXZ model) in equilibrium with a reservoir at temperature T as the resource used by Alice and Bob to implement the teleportation protocol. We show that the efficiency of this pair of spins to teleport a qubit is drastically affected after we cross a quantum critical point (QCP), even for high values of T. Also, we show that the present tool is as sharp as quantum discord (QD) to spotlight a QCP, where QD is the best finite T QCP detector known to date. Contrary to QD, however, we show that the present tool is easier to compute theoretically and has a direct experimental and operational meaning.

description: Mass-to-flux ratios measured via the Zeeman effect suggest the existence of a transition from a magnetically sub-critical state in HI clouds to a super-critical state in molecular clouds. However, due to projection, chemical, and excitation effects, Zeeman measurements are subject to a number of biases, and may not reflect the true relations between gravitational and magnetic energies. In this paper, we carry out simulations of the formation of magnetised molecular clouds, zooming in from an entire galaxy to sub-pc scales, which we post-process to produce synthetic HI and OH Zeeman measurements. The mass-to-flux ratios we recover from the simulated observations show a transition in magnetic criticality that closely matches observations, but we find that the gravitational-magnetic energy ratios on corresponding scales are mostly super-critical, even in the HI regime. We conclude that HI clouds in the process of assembling to form molecular clouds are already super-critical even before H_2 forms, and that the apparent transition from sub- to super-criticality between HI and H_2 is primarily an illusion created by chemical and excitation biases affecting the Zeeman measurements.

Theatre Group

description: Théâtre Instant Présent is an artistic and political project initiated in 2005 and has since been actively engaged in various activities across France. The group’s primary objective is to promote theatrical engagement for people from all walks of life, encompassing professionals and amateurs, focusing on those often distanced from cultural institutions. Consequently, the company offers a range of programs and initiatives, including:
1. Productions featuring individuals in situations of disability, exclusion, or illness.
2. Training opportunities for professionals, such as social workers and psychologists, who aim to incorporate drama workshops into social, medical-social, or healthcare settings.
3. Acting workshops for professionals from various artistic disciplines, including actors, singers, and dancers.
4. Workshops designed for amateur participants.
The artistic creations at Théâtre Instant Présent are grounded in improvisation and the clown figure. The theatre aims to connect with reality, emphasizing sensitivity, poetic expression, and humour. Productions featuring marginalized individuals, social workers, and actors represent a fusion of artistic, social, and communal approaches. Collaborating with individuals facing disabilities, exclusion, or illness allows those who have been silenced or unable to communicate to express their unique experiences and perspectives on the world, sharing them with the audience, which results in both personal and collective emancipation.
This emancipation is an individual journey, as acting allows individuals to explore new emotions, sensations, and thoughts, breaking free from potentially alienating existences. Amateur actors regain control of their place and voice within society. Language, voice, words, movement, stage presence, and active listening all play a supportive role in this process.
Collective emancipation occurs through the staging of improvisations that take place during workshops. The artistic project intertwines theatre with reality, addressing specific challenges participants face (e.g., disability, exclusion, unemployment) and universal themes (e.g., love, solidarity, difference, sexuality). These productions prompt inquiries into the concept of living together, reflecting a noble understanding of politics: How do we coexist harmoniously?
The emancipatory dimension extends to the audience, offering a fresh perspective on individuals occasionally perceived as “the others.” The theatrical representation encourages critical thinking, fosters sharing, encourages empathy, facilitates dialogue, and enables self-expression. In addition to its commitment to social theatre, Théâtre Instant Présent aims to cultivate the development of social theatre facilitators, potentially allowing the establishment of workshops for marginalized individuals facing disabilities, thereby making theatre practice accessible to all.

description: If dark matter is composed of neutralinos, one of the most exciting prospects for its detection lies in observations of the gamma-ray radiation created in pair annihilations between neutralinos, a process that may contribute significantly to the extragalactic gamma-ray background (EGB) radiation. We here use the high-resolution Millennium-II simulation of cosmic structure formation to produce the first full-sky maps of the expected radiation coming from extragalactic dark matter structures. Our map making procedure takes into account the total gamma-ray luminosity from all haloes and their subhaloes, and includes corrections for unresolved components of the emission as well as an extrapolation to the damping scale limit of neutralinos. Our analysis also includes a proper normalization of the signal according to a specific supersymmetric model based on minimal supergravity. The new simulated maps allow a study of the angular power spectrum of the gamma-ray background from dark matter annihilation, which has distinctive features associated with the nature of the annihilation process and may be detectable in forthcoming observations by the recently launched FERMI satellite. Our results are in broad agreement with analytic models for the gamma-ray background, but they also include higher-order correlations not readily accessible in analytic calculations and, in addition, provide detailed spectral information for each pixel. In particular, we find that difference maps at different energies can reveal cosmic large-scale structure at low and intermediate redshifts. If the intrinsic emission spectrum is characterized by an emission peak, cosmological tomography with gamma ray annihilation radiation is in principle possible.

title: An Investigation of the Change in Motivation of Fifth-Grade Students on Writing Activities After Being Taught Computer Programming Using Similar Teaching Strategies
Creators: name: Boyles, Raymond E.
Publisher: name: Utah State University

description: The implementation of collaboration and the use of graphic organizers in the teaching of programming and writing in the elementary grades have proven to be effective instructional strategies. There is evidence that shows the students who are motivated to program and perform well in this content area are not necessarily representative of the students who are motivated to write. Since the organizational skills required in the two content areas are similar, there may be an opportunity to motivate students who engage in computer programming to become more motivated in writing. As a result, the purpose of this study was to investigate the change in the dimensions of motivation which are: challenge, choice, enjoyment, and interest of fifth-grade students to engage in an expository writing activity after being taught to develop computer programs with the same teaching strategies used in the writing activity.
The results of this study suggest that the teaching of computer programming was not effective with the intention of motivating the masses of fifth-grade students to write. However, there appears to be supporting evidence that teaching computer programming to fifth-grade students may help some individual students who are not initially motivated to write.
