description: Helicopter parenting refers to the over-involved behavior of parents and/or caregivers who are highly invested and concerned for the well-being of their children. Helicopter parents typically engage in behaviors designed to remove obstacles from their children’s way. Although helicopter parents likely have good intentions for their children, as a child’s need for autonomy progresses, it is important to adjust the level of involvement and control accordingly. The present study represents an initial investigation into the relationship between helicopter parenting behaviors and the well-being of young university students. Participants consisted of 120 college students in their second semester of freshman year and 25 parents of student participants. Students completed measures of helicopter parenting for up to two parents/caregivers (e.g., mother and/or father), parents completed a self-report measure of helicopter parenting, and all participants completed self-report measures of anxiety and depression. Students who reported high levels of helicopter parenting behavior for the parent/caregiver with whom they have the most contact reported significantly higher levels of anxious arousal and lower grade point averages. Female parents/caregivers were reported to exhibit significantly greater helicopter parenting than that of male parents/caregivers. Male students perceived higher levels of helicopter parenting behaviors than female students. Student and parent reports of helicopter parenting were positively correlated with a large correlation coefficient, suggesting concordance between parent and child reports.

description: This paper reviews the field of Game AI, which not only deals with creating agents that can play a certain game, but also with areas as diverse as creating game content automatically, game analytics, or player modelling. While Game AI was for a long time not very well recognized by the larger scientific community, it has established itself as a research area for developing and testing the most advanced forms of AI algorithms and articles covering advances in mastering video games such as StarCraft 2 and Quake III appear in the most prestigious journals. Because of the growth of the field, a single review cannot cover it completely. Therefore, we put a focus on important recent developments, including that advances in Game AI are starting to be extended to areas outside of games, such as robotics or the synthesis of chemicals. In this article, we review the algorithms and methods that have paved the way for these breakthroughs, report on the other important areas of Game AI research, and also point out exciting directions for the future of Game AI.

description: Opaque detectors are a recently proposed novel detector concept where an opaque scintillator aligned with wavelength-shifting fibers is used to enable the discrimination of electron neutrinos and antineutrinos with a rather low energy threshold. In this work, we investigate the potential effects of the enhanced detection capabilities of the opaque detectors in accelerator neutrino experiments. Focusing on the energy threshold, energy resolution, detection efficiency and background suppression in the analysis of electron-like events, we determine whether using opaque detectors could lead to improvements in the CP violation and light sterile neutrino searches in the future accelerator neutrino experiments. We also identify the minimum requirements for the opaque detectors to reach the designated physics goals in the simulated experiments. We find that a 75.6% fraction of $δ_{CP}$ values could be reached for CP violation discovery by 3$σ$ confidence level or better when opaque detectors of 120 kton and 130 kton fiducial masses are used together with neutrino beams from J-PARC and MOMENT, respectively, whereas near detectors placed about 250 m from sources are sufficient to exclude the gallium anomaly at 2$σ$ confidence level.

description: In two-flavor dense quark matter, we describe the dynamics in the single plane wave Larkin--Ovchinnikov--Fulde--Ferrell (LOFF) state satisfying the color and electric neutrality conditions. We find that because the neutral LOFF state itself suffers from a chromomagnetic instability in the whole region where it coexists with the (gapped/gapless) two-flavor superconducting (2SC/g2SC) phases, it cannot cure this instability in those phases. This is unlike the recently revealed gluonic phase which seems to be able to resolve this problem.

description: Ischemic brain injuries are frequent and difficult to detect reliably or early. We present the multi-modal data set containing cardiovascular (blood pressure, blood flow, electrocardiogram) and brain electrical activities to derive electroencephalogram (EEG) biomarkers of corticothalamic communication under normal, sedation and hypoxic/ischemic conditions with ensuing recovery. We provide technical validation using EEGLAB. We also delineate the corresponding changes in the electrocardiogram (ECG)-derived heart rate variability (HRV) with the potential for future in-depth analyses of joint EEG-ECG dynamics. We review an open-source methodology to derive signatures of coupling between the ECoG and electrothalamogram (EThG) signals contained in the presented data set to better characterize the dynamics of thalamocortical communication during these clinically relevant states. The data set is presented in full band sampled at 2000 Hz, so the additional potential exists for insights from the full-band EEG and high-frequency oscillations under the bespoke experimental conditions. Future studies on the dataset may contribute to the development of new brain monitoring technologies, which will facilitate the prevention of neurological injuries.

Marie-Guillemine Benoist’s Portrait of a Black Woman (1800) as Tête d’Éxpression

description: Is Marie-Guillemine Benoist’s Portrait of a Black Woman (1800) an affirmational portrait of an individual? Or is it a vehicle for a racially-charged stereotype? I argue that the painting is suspended between these possibilities, largely because Benoist was trying to represent a newly acknowledged category of person: the Black female citizen. The painting’s ambiguities—its strange combination of physical specificity with generalization or typology—stem from the lack of precedents for the depiction of a free, equal Black woman. This brings me to my second contention: that Benoist turned to the genre of the tête d’expression (“expressive head”) as a way to represent her sitter. Developed by painter and theorist Charles Le Brun (1619-1690), the tête d’expression is a sub-genre related to history painting. Straddling portraiture and history painting, the tête d’expression was a crucial tool for artists to practice depicting a range of different facial expressions. The genre was also, at this time, particularly associated with women artists, who used it to demonstrate their mastery of human physiognomy and anatomy, and to display their skill without appearing overly ambitious or indecorous. I argue that by changing the identification of this painting from a “portrait” to a “tête d’expression,” we can better understand the tensions between allegory and specificity in Portrait of a Black Woman. In turn, this furthers our understanding of Benoist’s ambitions and inventiveness as a female artist.

description: The current study assesses a self-compassion writing task as an intervention for body dissatisfaction in women with varying levels of disordered eating while considering the effects of both positive and negative affect as well as shame. Seventy-one women between the ages of 18 and 30 completed several questionnaires along with a 15-minute self-compassionate letter writing task. Intervention interacted with disordered eating to predict changes in body dissatisfaction, such that those with less disordered eating were less dissatisfied with their bodies following the self-compassion writing task, B = -0.015, se(B) = 0.006, t(64) = -2.694, p = 0.009. There was an indirect effect of intervention on changes in body dissatisfaction through changes in shame, B = -0.142, se(B) = .063, 95% CI = -0.278, -0.032. There was a significant reduction in negative affect, F(1, 68) = 7.829, p = .007, partial η2 = .103, and shame, F(1, 68) = 8.106, p = .006, partial η2 = .107, in the self-compassion group. This study provides support for the use of self-compassionate letter writing as an intervention for body dissatisfaction in women with low levels of disordered eating and demonstrates that such interventions can be useful in reducing shame and negative affect more generally.
From Public Data to Private Information: The Case of the Supermarket

description: The background to this paper is that in our world of massively increasing personal digital data any control over the data about me seems illusionary - informational privacy seems a lost cause. On the other hand, the production of this digital data seems a necessary component of our present life in the industrialized world. A framework for a resolution of this apparent dilemma is provided if by the distinction between (meaningless) data and (meaningful) information. I argue that computational data processing is necessary for many present-day processes and not a breach of privacy, while collection and processing of private information is often not necessary and a breach of privacy. The problem and the sketch of its solution are illustrated in a case-study: supermarket customer cards.

description: We present an analytic toy model for the radiation produced by the interaction between the cold streams thought to feed massive halos at high redshift and their hot CGM. We begin by deriving cosmologically motivated parameters for the streams as they enter the halo virial radius, $R_{\rm v}$, as a function of halo mass and redshift. For $10^{12}M_{\odot}$ halos at $z=2$, we find the Hydrogen number density in streams to be $n_{\rm H,s}\sim (0.1-5)\times 10^{-2}{\rm cm}^{-3}$, a factor of $δ\sim (30-300)$ times denser than the hot CGM density, while the stream radii are in the range $R_{\rm s}\sim (0.03-0.50)R_{\rm v}$. As the streams accelerate towards the halo centre, they become denser and narrower. The stream-CGM interaction induces Kelvin-Helmholtz Instability (KHI), which leads to entrainment of CGM mass by the stream and therefore to stream deceleration by momentum conservation. Assuming that the entrainment rates derived by Mandelker et al. 2019 in the absence of gravity can be applied locally at each halocentric radius, we derive equations of motion for the stream in the halo. Using these, we derive the net acceleration, mass growth, and energy dissipation induced by the stream-CGM interaction, as a function of halo mass and redshift, for different CGM density profiles. For the range of model parameters considered, we find that the interaction can induce dissipation luminosities $L_{\rm diss}>10^{42}~{\rm erg~s^{-1}}$ within $\le 0.6 R_{\rm v}$ of halos with $M_{\rm v}>10^{12}M_{\odot}$ at $z=2$, with the emission scaling with halo mass and redshift approximately as $\propto M_{\rm v}\,(1+z)^2$. The magnitude and spatial extent of the emission produced in massive halos at high redshift is consistent with observed Ly$α$ blobs, though better treatment of the UV background and self-shielding is needed to solidify this conclusion.

description: We have studied the low-temperature properties of Pr$_{x}$La$_{1-x}$Pb$_{3}$ with non-Kramers $Γ_{3}$ quadrupolar moments of the crystal-electric-field ground state, for a wide concentration range of Pr ions. For $x$$\le$0.05, the specific heat $C/T$ increases monotonically below $T$=1.5 K, which can be scaled with a characteristic temperature $T^{*}$ defined at each concentration $x$. The electrical resistivity $ρ$$(T)$ in the corresponding temperature region shows a marked decrease deviating from a Fermi-liquid behavior $ρ$$(T)$$\propto$$T^{2}$. The Kondo effect arising from the correlation between the dilute $Γ_{3}$ moments and the conduction electrons may give rise to such anomalous behavior.

description: It is common to compare individualized treatment rules based on the value function, which is the expected potential outcome under the treatment rule. Although the value function is not point-identified when there is unmeasured confounding, it still defines a partial order among the treatment rules under Rosenbaum's sensitivity analysis model. We first consider how to compare two treatment rules with unmeasured confounding in the single-decision setting and then use this pairwise test to rank multiple treatment rules. We consider how to, among many treatment rules, select the best rules and select the rules that are better than a control rule. The proposed methods are illustrated using two real examples, one about the benefit of malaria prevention programs to different age groups and another about the effect of late retirement on senior health in different gender and occupation groups.

The Cognitive and Subjective Effects of Chronic Caffeinated Energy Drink Consumption in Young Adults
Creators: name: Murani, Kristina
Publisher: name: American University
Year: 2023

description: Caffeinated beverages, including energy drinks (EDs), are widely consumed for their purported cognitive enhancing effects. Most prior research studies on the cognitive effects of caffeine have examined acute effects; however, caffeine is most often consumed in a chronic fashion. Furthermore, chronic caffeine consumption can produce tolerance and physical dependence, which manifests as cognitive and emotional disruptions upon acute abstinence. The present study investigated the attentional and subjective effects of caffeinated EDs consumed daily for three weeks. It has been proposed that attention can be divided into three networks—alerting, orienting and executive control (Posner & Peterson, 1990), which are often assessed with the Attention Network Task (ANT; Fan et al., 2002). Thirty-seven light non-dependent caffeine consumers (43.2% female; mean daily caffeine use = 81.26 mg) participated in a six week within-subjects study. After a one-week baseline period, participants consumed one week of daily placebo EDs, followed by three weeks of daily caffeinated EDs (200 mg), and then one week of daily placebo EDs. Reactions to the EDs were assessed in the laboratory across nine different timepoints. Consumption of caffeinated EDs (timepoints 4, 5, and 6) produced faster reaction times (RTs) but no differences for percent error and the three attention networks compared to placebo EDs (timepoints 3, 7, and 8). Acute caffeinated ED exposure (timepoint 4) produced faster RTs and improvements in executive control than the placebo ED (timepoint 3), but no differences for percent error or the alerting and orienting networks. Greater mood disturbances and withdrawal symptoms were observed in response to the placebo ED (timepoints 7 or 8; 24 and 48 hours of abstinence, respectively) that was consumed after three weeks of daily caffeinated EDs when compared to the placebo ED that was consumed prior to caffeine exposure (timepoint 3). The unexpected effects of caffeine and acute caffeine abstinence on ANT performance warrant future inquiry. The findings from the present study suggest that physical dependence develops after only three weeks of daily moderate caffeine exposure and have implications for the use of caffeinated EDs for cognitive enhancement.

description: Detecting and labeling stance in social media text is strongly motivated by hate speech detection, poll prediction, engagement forecasting, and concerted propaganda detection. Today's best neural stance detectors need large volumes of training data, which is difficult to curate given the fast-changing landscape of social media text and issues on which users opine. Homophily properties over the social network provide strong signal of coarse-grained user-level stance. But semi-supervised approaches for tweet-level stance detection fail to properly leverage homophily. In light of this, We present SANDS, a new semi-supervised stance detector. SANDS starts from very few labeled tweets. It builds multiple deep feature views of tweets. It also uses a distant supervision signal from the social network to provide a surrogate loss signal to the component learners. We prepare two new tweet datasets comprising over 236,000 politically tinted tweets from two demographics (US and India) posted by over 87,000 users, their follower-followee graph, and over 8,000 tweets annotated by linguists. SANDS achieves a macro-F1 score of 0.55 (0.49) on US (India)-based datasets, outperforming 17 baselines (including variants of SANDS) substantially, particularly for minority stance labels and noisy text. Numerous ablation experiments on SANDS disentangle the dynamics of textual and network-propagated stance signals.

Our results are in good agreement with the BESIII measurements, and it is found that the anomalous enhancement near the $\bar{p}Λ$ threshold is mainly due to the contribution of the $K(1830)$ resonance. We also show that the interference of the high-mass $N^*$ and $Λ^*$ can not produce the anomalous enhancement near the $\bar{p}Λ$ threshold.

description: We have identified over 2000 well resolved cluster halos, and also their associated bound subhalos, from the output of a 1024^3 particle cosmological N-body simulation (of box size 320 h^-1 Mpc and softening length 3.2 h^-1 kpc). This has allowed us to measure halo quantities in a statistically meaningful way, and for the first time analyse their distribution for a large and well resolved sample. We characterize each halo in terms of its morphology, concentration, spin, circular velocity and the fraction of their mass in substructure. We also identify those halos that have not yet reached a state of dynamical equilibrium using the virial theorem with an additional correction to account for the surface pressure at the boundary. These amount to 3.4% of our initial sample. For the virialized halos, we find a median of 5.6% of halo mass is contained within substructure, with the distribution ranging between no identified subhalos to 65%. The fraction of mass in substructure increases with halo mass with logarithmic slope of 0.44 +- 0.06. Halos tend to have a prolate morphology, becoming more so with increasing mass. Subhalos have a greater orbital angular momentum per unit mass than their host halo. Furthermore, their orbital angular momentum is typically well aligned with that of their host. Overall, we find that dimensionless properties of dark matter halos do depend on their mass, thereby demonstrating a lack of self-similarity.

We measure the relative importance of exchange rate distortions for rice and wheat in five developing countries, 1982-1987, and find that exchange rate distortions have {in many cases) completely offset positive sectoral policy interventions, to the detriment of agricultural producers in developing countries.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
The central dark matter fraction of massive early-type galaxies

description: Dark matter (DM) is predicted to be the dominant mass component in galaxies. In the central region of Early-type galaxies it is expected to account for a large amount of the total mass, although the stellar mass should still represent the majority of the mass budget, depending on the stellar Initial Mass Function (IMF). We discuss latest results on the DM fraction and mean DM density for local galaxies and explore their evolution with redshifts in the last 8 Gyr of the cosmic history. We compare these results with expectations from the $\Lambda$CDM model, and discuss the the role of the IMF and galaxy model, through the central total mass density slope. We finally present future perspectives offered by next generation instruments/surveys (Rubin/LSST, Euclid, CSST, WEAVE, 4MOST, DESI), that will provide the unique chance to measure the DM evolution with time for an unprecedented number of galaxies and constrain their evolutionary scenario.

description: It has been noticed that confinement effects can be described by the addition of a $ \sqrt {- F_{μν}^a F^{aμν}} $ term in the Lagrangian density. We now study the combined effect of such "confinement term" and that of a mass term. The surprising result is that the interplay between these two terms gives rise to a Coulomb interaction. Our picture has a certain correspondence with the quasiconfinement picture described by Giles, Jaffe and de Rujula for QCD with symmetry breaking.

description: Many macro policy models assume that changes in the real exchange rate have similar impacts on different production activities within agriculture. This paper discusses the importance of intrasectoral heterogeneity in the degree of tradability and in the characteristics of production functions in estimating effects of real exchange rate changes.

description: Airborne gamma-ray surveys are useful for many applications, ranging from geology and mining to public health and nuclear security. In all these contexts, the ability to decompose a measured spectrum into a linear combination of background source terms can provide useful insights into the data and lead to improvements over techniques that use spectral energy windows. Multiple methods for the linear decomposition of spectra exist but are subject to various drawbacks, such as allowing negative photon fluxes or requiring detailed Monte Carlo modeling. We propose using Non-negative Matrix Factorization (NMF) as a data-driven approach to spectral decomposition. Using aerial surveys that include flights over water, we demonstrate that the mathematical approach of NMF finds physically relevant structure in aerial gamma-ray background, namely that measured spectra can be expressed as the sum of nearby terrestrial emission, distant terrestrial emission, and radon and cosmic emission. These NMF background components are compared to the background components obtained using Noise-Adjusted Singular Value Decomposition (NASVD), which contain negative photon fluxes and thus do not represent emission spectra in as straightforward a way. Finally, we comment on potential areas of research that are enabled by NMF decompositions, such as new approaches to spectral anomaly detection and data fusion.

description: One of the key challenges in magnetism remains the determination of the nanoscopic magnetization profile within the volume of thick samples, such as permanent ferromagnets. Thanks to the large penetration depth of neutrons, magnetic small-angle neutron scattering (SANS) is a powerful technique to characterize bulk samples. The major challenge regarding magnetic SANS is accessing the real-space magnetization vector field from the reciprocal scattering data. In this letter, a fast iterative algorithm is introduced that allows one to extract the underlying two-dimensional magnetic correlation functions from the scattering patterns. This approach is used here to analyze the magnetic microstructure of Nanoperm, a nanocrystalline alloy which is widely used in power electronics due to its extraordinary soft magnetic properties. It can be shown that the computed correlation functions clearly reflect the projection of the three-dimensional magnetization vector field onto the detector plane, which demonstrates that the used methodology can be applied to probe directly spin-textures within bulk samples with nanometer-resolution.

X-ray flares from the ultra-luminous X-ray source in NGC 5408

description: We have studied an ultra-luminous X-ray source (ULX) in the dwarf galaxy NGC 5408 with a series of XMM-Newton observations, between 2001 July and 2003 January. We find that its X-ray spectrum is best fitted with a power law of photon index Gamma ~ 2.6--2.9 and a thermal component with blackbody temperature kT_bb ~ 0.12--0.14 keV. These spectral features, and the inferred luminosity ~ 10^{40} erg/s in the 0.3--12 keV band, are typical of bright ULXs in nearby dwarf galaxies. The blackbody plus power-law model is a significantly better fit than either a simple power law or a broken power law (although the latter model is also acceptable at some epochs). Doppler-boosted emission from a relativistic jet is not required, although we cannot rule out this scenario. Our preliminary timing analysis shows flaring behaviour which we interpret as variability in the power-law component, on timescales of ~ 10^2 s. The hard component is suppressed during the dips, while the soft thermal component is consistent with being constant. The power density spectrum is flat at low frequencies, has a break at f_b ~ 2.5 mHz, and has a slope ~ -1 at higher frequencies. A comparison with the power spectra of Cyg X-1 and of a sample of other BH candidates and AGN suggests a mass of ~ 10^2 M_sun. It is also possible that the BH is at the upper end of the stellar-mass class (M ~ 50 M_sun), in a phase of moderately super-Eddington accretion. The formation of such a massive BH via normal stellar evolution may have been favoured by the very metal-poor environment of NGC 5408.

LEE MILLER’S “HITLERIANA” AND THE VISUAL CULTURE OF WAR-TIME ENGLAND
Creators: name: Carr, Caitlyn E.
Publisher: name: American University
Year: 2023

description: Throughout World War II, American photographer Lee Miller (1907-1977) served as a war correspondent for Condé Nast. As she followed the 273rd infantry regiment of the 45th division of the United States Army, Miller published photo essays in American, British, and French Vogue. On April 30, 1945, the day that Hitler killed himself in a Berlin bunker, Miller and her partner, Dave Scherman, found themselves in his Munich apartment. Miller proceeded to photograph some of his belongings, and she and Scherman staged a photograph in the deceased chancellor’s bathroom. This thesis examines the resulting photospread, “Hitleriana,” which was published in the July 1945 issue of British Vogue. Scholars have attended to one of the photographs in the spread, Lee Miller in Hitler’s Bath (1945), and argued that it speaks to Miller’s recent harrowing experience covering the liberation of Nazi concentration camps, her time as a photojournalist, and her interest in Surrealism. Rather than approaching this one photograph biographically, my thesis explains how and why the spread as whole, including Lee Miller in Hitler’s Bath, responds to the visual culture of the Third Reich and of Hitler in particular. Reading the photographs in relation to one another, to the essay that accompanied them, and to the visual culture of World War II more broadly, this thesis argues that the spread worked to counteract more traditional depictions of Adolf Hitler. Official Nazi imagery and popular film depicted Hitler as a larger than life, mythic figure. In “Hitleriana,” Lee Miller reveals his mortality and critiques the culture industry that would have readers see him otherwise.
Dynamical charge inhomogeneity and crystal-field fluctuations for 4f ions in high-Tc cuprates

description: The main relaxation mechanism of crystal-field excitations in rare-earth ions in cuprates is believed to be provided by the fluctuations of crystalline electric field induced by a dynamic charge inhomogeneity generic for the doped cuprates. We address the generalized granular model as one of the model scenario for such an ingomogeneity where the cuprate charge subsystem remind that of Wigner crystal with the melting transition and phonon-like positional excitation modes. Formal description of R-ion relaxation coincides with that of recently suggested magnetoelastic mechanism.

Notes. – The only specimen of original material in the Burman herbarium is designated here as the lectotype. This collection is annotated as “rompot laut javanis” [“sea grass by the Javanese”] and represents a staminate plant. Houttuyn was clearly confused about this species, which he discussed twice, obviously unaware that it is dioecious. The single collection in his Ceylon herbarium [G00818158] also is a staminate plant of Spinifex littoreus.

description: Although food aid has been advocated for countries undertaking structural adjustment policies, political support for increased aid expenditures is lacking. Countertrade is proposed herein as a method for expanding food aid without increasing expenditures. Countertrade allows developing countries to accelerate growth in their export sectors while "financing" increased food assistance.
