description: Quality controlled and homogenized radiosonde observations have been used to validate decadal hindcasts of the MPI-Earth-System-Model for Europe (excl. some Eastern European countries). Simulated temperatures have a cold bias of 1 to 4 K, increasing with height throughout the free troposphere over Europe. This implies that the simulated troposphere is less stable than observed by the radiosondes over Europe. Simulated relative humidity is 10 to 40 % higher than observed. Part of the humidity bias, 10 to 25 % relative humidity, is due to the simulated lower temperature, but the remainder indicates that modelled water vapour pressure is too high in the free troposphere above Europe. After full-field initialization with oceanic state, the atmospheric temperature bias changes over the first couple of years, with a relaxation time of 5 years near the surface (850 hPa) and less than 1 year near the tropopause (200 hPa). Anomaly correlations, mean-square error and logarithmic ensemble spread score indicate small improvements in hindcasted tropospheric temperatures over Europe when going from ocean anomaly initialisation to ocean anomaly initialisation plus full field atmospheric initialisation, and then to full field ocean initialisation plus full field atmospheric initialisation. In the stratosphere, these changes have little effect. For humidity, correlations and skill scores are much poorer, and little can be said about changes over Europe due to different initializations.

description: The internal dynamics of multiple stellar populations in Globular Clusters (GCs) provides unique constraints on the physical processes responsible for their formation. Specifically, the present-day kinematics of cluster stars, such as rotation and velocity-dispersion, could be related to the initial configuration of the system. In recent work, we provided the first study of the kinematics of different stellar populations in NGC$\,$0104 over a large field of view in the plane of the sky, exploiting Gaia Data Release 2 (DR2) proper motions combined with multi-band ground-based photometry. In this paper, we combine Gaia DR2 proper motions with Very Large Telescope radial velocities to investigate the kinematics along the line of sight and in the plane of the sky of multiple populations in seven GCs, namely NGC$\,$0104, NGC$\,$0288, NGC$\,$5904, NGC$\,$6121, NGC$\,$6254, NGC$\,$6752 and NGC$\,$6838. Among the analyzed clusters only NGC$\,$0104 and NGC$\,$5904 show significant rotation. Separating our sample into two groups of first- and second-population stars (1P and 2P) we find that overall these two populations exhibit a similar rotation pattern in NGC$\,$0104. However, some hints of different rotation are observed in the external regions of this cluster. Interestingly, 1P and 2P stars in NGC$\,$5904 show different rotation curves, with distinct phases and such difference is significant at the $\sim$2.5-$σ$ level. The analysis of the velocity-dispersion profiles of multiple populations confirms that 2P stars of NGC$\,$0104 show stronger anisotropy than the 1P.

description: In this paper we study the behavior of Hamilton operators and their spectra which depend on infinitely many coupling parameters or, more generally, parameters taking values in some Banach space. One of the physical models which motivate this framework is a quantum particle moving in a more or less disordered medium. One may however also envisage other scenarios where operators are allowed to depend on interaction terms in a manner we are going to discuss below. The central idea is to vary the occurring infinitely many perturbing potentials independently. As a side aspect this then leads naturally to the analysis of a couple of interesting questions of a more or less purely mathematical flavor which belong to the field of infinite dimensional holomorphy or holomorphy in Banach spaces. In this general setting we study in particular the stability of selfadjointness of the operators under discussion and the analyticity of eigenvalues under the condition that the perturbing potentials belong to certain classes.

Towards Data-driven Simulation of End-to-end Network Performance Indicators

Year: 2019
Subjects: subject: Networking and Internet Architecture (cs.NI)

description: Novel vehicular communication methods are mostly analyzed simulatively or analytically as real world performance tests are highly time-consuming and cost-intense. Moreover, the high number of uncontrollable effects makes it practically impossible to reevaluate different approaches under the exact same conditions. However, as these methods massively simplify the effects of the radio environment and various cross-layer interdependencies, the results of end-to-end indicators (e.g., the resulting data rate) often differ significantly from real world measurements. In this paper, we present a data-driven approach that exploits a combination of multiple machine learning methods for modeling the end-to-end behavior of network performance indicators within vehicular networks. The proposed approach can be exploited for fast and close to reality evaluation and optimization of new methods in a controllable environment as it implicitly considers cross-layer dependencies between measurable features. Within an example case study for opportunistic vehicular data transfer, the proposed approach is validated against real world measurements and a classical system-level network simulation setup. Although the proposed method does only require a fraction of the computation time of the latter, it achieves a significantly better match with the real world evaluations.

description: Periodontitis is a highly prevalent chronic inflammatory disease affecting more than 60% of the population, which leads to destruction of the tooth-supporting tissues. The periodontium is composed of both hard (bone and cementum) and soft tissues (periodontal ligament and gingiva), requiring a tissue-engineering approach to allow a precisely coordinated and compartmentalised healing response for subsequent structural and functional regeneration. The present study investigated the functionalisation of highly porous scaffolds with decellularised cell-laid extracellular matrix for periodontal regeneration. This novel technique allowed the combination of a three-dimensional scaffold providing mechanical support with a native ECM providing tissue specific biological activity. The decellularisation of such constructs allows the maintenance of an intact ECM structure and composition while removing the immunogenic cellular component, thus generating an acellular implant. By combining a bone-like ECM-decorated scaffold (bone compartment) with periodontal ligament cell-sheets (PDLcs), the aim was to achieve specific bone and periodontal ligament regeneration. [...]

Technique and practice : shell-working in the Western Pacific and island Southeast Asia
Creators: name: Szabo, Katherine Anne
Publisher: name: The Australian National University
Year: 2004

description: The Lapita cultural complex has been a focal point of Pacific archaeology for many years. Not only is it materially distinctive, but it is also cast as signalling the first colonisation the western Pacific beyond the main Solomon Islands chain, the introduction of a neolithic way of life to this area, and providing the cultural base from which later Polynesian cultures emerge. The 'origins' of the Lapita cultural complex have also been a major area of interest, and there has been much debate as to how much Lapita owes to the Island Southeast Asian neolithic, and how much of the culture represents a continuation of Near Oceanic cultural trajectories. Despite all this debate, archaeological material from Island Southeast Asia, pre-Lapita Near Oceania and the Lapita cultural complex itself, has never been physically compared in any systematic way. This task forms the basis of the research presented here. Artefacts produced in shell have been central to arguments for both Lapita representing an 'extension' of the Island Southeast Asian neolithic and a local trajectory encompassing the neolithic transition in Near Oceania. It was thus felt that a controlled comparison of worked shell material across Island Southeast Asia and the western Pacific, deriving from different temporal contexts, would be fruitful. The issue of social and ancestral relationships, both through time and across space, is a challenging one to address. Necessarily, it broaches on longstanding disagreements within archaeology as a whole, such as the status of diffusion as a mechanism for social change and the issue of 'homology' versus 'analogy'. Thus, as well as presenting the results of the conducted analysis, this thesis details new theoretical and methodological perspectives that have both structured the overall approach and facilitated interpretation. Through the application of a rigorous methodology, situated within a transparent theoretical framework, clear patterns have emerged. The results do not agree with either 'intrusionist' or 'indigenist' arguments for the genesis of the Lapita cultural complex. Rather, they suggest widespread relationships in shell­ working practices across the Island Southeast Asia/western Pacific area that have a considerable time-depth.

description: The elastic scattering properties of three bosons at low energy enter the many-body description of ultracold Bose gases via the three-body scattering hypervolume $D$. We study this quantity for identical bosons that interact via a pairwise finite-range potential. Our calculations cover the regime from strongly repulsive potentials towards attractive potentials supporting multiple two-body bound states and are consistent with the few existing predictions for $D$. We present the first numerical confirmation of the universal predictions for $D$ in the strongly interacting regime, where Efimov physics dominates, for a local nonzero-range potential. Our findings highlight how $D$ is influenced by three-body quasibound states with strong $d$-wave or $g$-wave characteristics in the weakly interacting regime.

description: Investment in addressing structural stigma and discrimination against refugees in resource-poor urban areas is both needed, and possible.  The large population of refugees residing in resource-poor urban areas is likely to grow, and tensions in a number of settings are now documented.  Without interventions to adequately address such tensions, both the protection needs of refugee populations and the stability of hosting countries could be affected.  Through qualitative analysis of an urban refugee dataset in Uganda, this dissertation identified community-level drivers of structural stigma and discrimination as safeguarding one’s body and property, defending status, and perpetuating exploitation.  The designs of potentially successful programs to address these drivers were then identified though systematic review, and included one or more of the following: 1) the utilization of multiple intervention components; 2) direct information provision (e.g., lecture, role-play, other active engagement) or direct contact with stigmatized groups; 3) cooperative work between community members and stigmatized groups to better livelihoods; 4) popular opinion leaders who have authority to make change, and 5) traditional ceremonies valued by the communities for cleansing and healing.  One such design involving an agricultural livelihood program in a resource-poor urban area of the Northeast United States was costed, utilizing a primarily bottom-up approach and a societal perspective in the collection of both financial and economic costs.  The unit cost per participating family was significantly lower than government services that provide comparable nutritional support, but did not include components of working with the community to reduce stigma and discrimination.  Thus, the studied program provided more services for a lower cost.  In addition, it empowered stigmatized refugees to advocate for and support themselves, and engendered goodwill in the community by involving community members to work alongside refugee participants, improving upon a neglected piece of land, and providing fresh produce.  Further research is needed to better measure the social and financial dividends of programs to address structural stigma and discrimination, particularly against urban refugees.  Such research can only come in tandem with further investment, the imperative and potential of which are compellingly clear.

description: Weyl semimetals are 3D phases of matter with topologically protected states that have remarkable macroscopic transport behaviors. As phonon dynamics and electron-phonon scattering play a critical role in the electrical and thermal transport, we pursue a fundamental understanding of the origin of these effects in type-I Weyl semimetals NbAs and TaAs. In the temperature-dependent Raman spectra of NbAs, we reveal a previously unreported Fano lineshape, a signature stemming from the electron-phonon interaction. Additionally, the temperature dependence of the $A_{1}$ phonon linewidths in both NbAs and TaAs strongly deviate from the standard model of anharmonic decay. To capture the mechanisms responsible for the observed Fano asymmetry and the atypical phonon linewidth, we present first principles calculations of the phonon self-energy correction due to the electron-phonon interaction. Finally, we investigate the relationship between Fano lineshape, electron-phonon coupling, and locations of the Weyl points in these materials. Through this study of the phonon dynamics and electron-phonon interaction in these Weyl semimetals, we consider specific microscopic pathways which contribute to the nature of their macroscopic transport.

Magnetoroton instabilities and static susceptibilities in higher Landau levels

description: We present analytical results concerning the magneto-roton instability in higher Landau levels evaluated in the single mode approximation. The roton gap appears at a finite wave vector, which is approximately independent of the LL index n, in agreement with numerical calculations in the composite-fermion picture. However, a large maximum in the static susceptibility indicates a charge density modulation with wave vectors $q_0(n)\sim 1/\sqrt{2n+1}$, as expected from Hartree-Fock predictions. We thus obtain a unified description of the leading charge instabilities in all LLs.

description: Externally-signalled apoptosis has been characterised as a “travelling wave of cell death” and its (finite) speed has been measured. This suggests the possibility of a kinetic contest or race between, on the one hand, the “wave of cell death” apoptosis front and, on the other hand, growing clusters of diseased cells. Diseased cells will be eliminated, and disease suppressed, provided the apoptosis front advances faster than the diseased clusters can grow.
Diseased cells will be more likely to outrun the apoptosis front and so become established in an organism if they can perform an initial, rapid growth ‘sprint’. Cancer cells may gain dynamism for such an initial growth spurt by deriving energy from aerobic glycolysis rather than oxidative phosphorylation

 C o m m e n t s: The description of Aleochara hellenica is based on a female holotype from "Etol.-Akar., O. Váltou, 2° polje NW di Perdikáki" deposited in the collection of Mauro Giachino (Torino). The details indicated in the original description, especially the illustration of the distinctive spermatheca, gave rise to the suspicion that A. hellenica was in fact a synonym of Haploglossa villosula. A subsequent examination of the holotype confirmed that it is doubtlessly conspecific with H. villosula; hence the synonymy proposed above.
 Haploglossa villosula has been recorded from Greece before (ASSING 2005g, LÖBL & SMETANA 2004). The species is widespread and common in Europe; a recent record from China (ASSING 2005e) shows that it is present also in the Eastern Palaearctic region.

description: We revisit the case of scalar dark matter interacting just gravitationally with the Standard Model (SM) particles in an extra-dimensional Randall-Sundrum scenario. We assume that both, the dark matter and the Standard Model, are localized in the TeV brane and only interact via gravitational mediators, namely the graviton Kaluza-Klein modes and the radion. We analyze in detail the dark matter annihilation channel into two on-shell KK-gravitons, and contrary to previous studies which overlooked this process, we find that it is possible to obtain the correct relic abundance for dark matter masses in the range [1, 10] TeV even after taking into account the strong bounds from LHC Run II. We also consider the impact of the radion contribution (virtual exchange leading to SM final states as well as on-shell production), which does not significantly change our results. Quite interestingly, a sizeable part of the currently allowed parameter space could be tested by LHC Run III and by the High-Luminosity LHC.

Islands in between : prehistory of the northeastern Indonesian archipelago
Creators: name: Tanudirjo, Daud Aris
Publisher: name: The Australian National University
Year: 2001

description: The northeastern Indonesian archipelago occupies a strategic location against the southwestern rim of the Pacific. It has been suggested that it served as a 'stepping stone' region for the migrations of people from Asia to Australia and Oceania in prehistory. Nevertheless, only limited archaeological research has been conducted in this area to date. Recently, further archaeological survey and excavation has been carried out here by me, especially in the Talaud (North Sulawesi) and Sula Islands (North Moluccas), in order to generate new data. This thesis presents the results of that recent research. The excavated archaeological materials demonstrate that humans have occupied this region since Late Pleistocene, at least 30,000 years ago. The cultural materials excavated from younger sites witness the spread of Austronesian-speaking agricultural peoples, probably from Taiwan into the Pacific about 4,000 years ago, as also supported by linguistic reconstruction. As these new data are incorporated into the available corpus of research information, the cultural processes that took place in northeastern Indonesia can be reconstructed in the wider regional context of Island Southeast Asia and Western Melanesia. A firmer cultural sequence for this area can now be established. In this thesis, a model for initial Pleistocene human colonization in Wallacea and Oceania is suggested. Furthermore, an alternative explanation for the dispersal of the Austronesian-speaking populations is also proposed.
Lepton mass effects for beam-normal single-spin asymmetry in elastic muon-proton scattering

description: We estimate the beam-normal single-spin asymmetry in elastic lepton-proton scattering without employing the ultrarelativistic approximation. Our calculation is relevant for analyses of muon scattering at energies of few hundred MeV and below -- when effects of the muon mass become essential. At such energies, the transverse polarization of the muon beam is expected to contribute significantly to the systematic uncertainty of precision measurements of elastic muon-proton scattering. We evaluate such systematics using an example of the MUSE experiment at PSI. The muon asymmetry is estimated at about 0.1\% in kinematics of MUSE and it is the largest for scattering into a backward hemisphere.

description: A pair of new neo-clerodane diterpenoid epimers, 3S-methoxyl-teucvin (1) and 3R-methoxyl-teucvin (2), were isolated from the Roots of Croton crassifolius. Their structures were completely established on the basis of spectroscopic methods, and the absolute configurations were determined by analysis of electronic circular dichroism (ECD) spectroscopy and X-ray diffraction analysis. Compounds 1 and 2 exhibited anti-inflammatory activities with IC50 values of 0.82 and 0.54 μM, respectively, while the IC50 value of dexamethasone as a positive control was found to be 0.14 μM.

description: The statistical properties of wave functions at the critical point of the spin quantum Hall transition are studied. The main emphasis is put onto determination of the spectrum of multifractal exponents $Δ_q$ governing the scaling of moments $\sim L^{-qd-Δ_q}$ with the system size $L$ and the spatial decay of wave function correlations. Two- and three-point correlation functions are calculated analytically by means of mapping onto the classical percolation, yielding the values $Δ_2=-1/4$ and $Δ_3=-3/4$. The multifractality spectrum obtained from numerical simulations is given with a good accuracy by the parabolic approximation $Δ_q\simeq q(1-q)/8$ but shows detectable deviations. We also study statistics of the two-point conductance $g$, in particular, the spectrum of exponents $X_q$ characterizing the scaling of the moments $$. Relations between the spectra of critical exponents of wave functions ($Δ_q$), conductances ($X_q$), and Green functions at the localization transition with a critical density of states are discussed.

Geological factors influencing dryland salinity risk
Creators: name: Tassell, Geoffrey William
Publisher: name: The Australian National University
Year: 1995

description: Dryland salinity has become a major environmental problem in Australia through changes in land management incurred since European settlement. Given appropriate conditions of land management and clin1ate, salinisation follows the advent of discharge areas which arise through rises in groundwater level and/or impediments to groundwater flow. Impediments may be structures such as dams, roads and railway embankments but can also occur naturally through geological features. Geological structures such as dykes, faults and contact zones may be impediments to groundwater flow as can changes to hydraulic conductivity through changes in the permeability of rocks and soils. Geological factors have been incorporated into a predictive model to identify areas at risk to salinisation. The model is a Decision Tree Analysis run via the Knowledge SEEKER computer program. Results from this modelling exercise are comparable with other models based on surface and near-surface flow and topographic indices but suffer from being site specific. The study highlights the need for development of improved methods of mapping subsurface features and for widespread changes to the current system of land management.

description: Coherent nonlinear multi-pulse processes, nonlinear waves and echo effects in resonant media are the topical problems of modern optics and important tools of coherent spectroscopy and quantum information science. We generalize the McCall-Hahn area theorem to the formation of an arbitrary photon echo generated during the multi-pulse excitation of the optically dense resonant media. The derived theorem made it possible to reveal the nonlinear mechanism of generation and evolution of the photon echo signals inside the media after a two-pulse excitation. We find that a series of self-reviving echo signals with total area of $2π$ or $0π$ is excited and propagates in the media depth, with each pulse having an individual area less than $π$. The resulting echo pulse train is a new alternative to the well-known soliton or breather. The developed pulse-area approach paves the way for more precise coherent spectroscopy, studies of different photon echo signals and quantum control of light pulses in the optically dense media.

description: We study the possibility of extracting the neutrino mass ordering at the future Deep Underground Neutrino Experiment using atmospheric neutrinos, which will be available before the muon neutrino beam starts being perational. The large statistics of the atmospheric muon neutrino and antineutrino samples at the far detector, together with the baselines of thousands of kilometers that these atmospheric (anti)neutrinos travel, provide the ideal ingredients to extract the neutrino mass ordering via matter effects in the neutrino propagation through the Earth. Crucially, muon capture by Argon provides excellent charge-tagging, allowing to disentangle the neutrino and antineutrino signature. This is a critical extra benefit of having a Liquid Argon Time Projection Chamber as far detector, that could render a $4σ$ extraction of the mass ordering after ten years of exposure.

Reciprocity and representation theorems for flux- and field-normalised decomposed wave fields
Creators: name: Wapenaar, Kees
Publisher: name: arXiv
Year: 2019
Subjects: subject: Geophysics (physics.geo-ph)
subject: FOS: Physical sciences

description: We consider wave propagation problems in which there is a preferred direction of propagation. To account for propagation in preferred directions, the wave equation is decomposed into a set of coupled equations for waves that propagate in opposite directions along the preferred axis. This decomposition is not unique. We discuss flux-normalised and field-normalised decomposition in a systematic way, analyse the symmetry properties of the decomposition operators and use these symmetry properties to derive reciprocity theorems for the decomposed wave fields, for both types of normalisation. Based on the field-normalised reciprocity theorems, we derive representation theorems for decomposed wave fields. In particular we derive double- and single-sided Kirchhoff-Helmholtz integrals for forward and backward propagation of decomposed wave fields. The single-sided Kirchhoff-Helmholtz integrals for backward propagation of field-normalised decomposed wave fields find applications in reflection imaging, accounting for multiple scattering.

Integrality of two variable Kostka functions

Publisher: name: arXiv
Year: 1996
Subjects: subject: Quantum Algebra (math.QA)
subject: FOS: Mathematics

description: The two variable Kostka functions are the scalar products of the Macdonald polynomials with the Schur polynomials with respect to the scalar product which makes the Hall-Littlewood polynomials pairwise orthogonal. A conjecture of Macdonald states that they are polynomials in q and t with non-negative integral coefficients. We prove that the Kostka functions are at least polynomials with integral coefficients. The main idea is to prove an analogous statement for the non-symmetric Macdonald polynomials by establishing recursion relations via the affine Hecke algebra.

description: Background. Reducing maternal mortality remains a significant challenge in Indonesia, especially for achieving the country’s Sustainable Development Goals (SDGs) by 2030. One of the challenges is increasing delivery at healthcare facilities to ensure safe and healthy births. In Indonesia, research on factors affecting women’s use of facility-based childbirth services is scarce. Objective. This study was conducted to identify the determinants of facility-based deliveries in Indonesia. Methods. This study used data from the Indonesia Demographic and Health Survey of 2012, with a cross-sectional design. An odds ratio with 95% confidence intervals (CI) was employed to outline the independent variables for the determinants, including maternal age and education, place of residence, involvement in decision-making, employment status, economic status, and number of antenatal care visits. The dependent variable in this study was the place of delivery: whether it took place in healthcare or nonhealthcare facilities. The statistical significance was set at p<0.05 using bivariate analysis and binary logistic regression. Results. This study showed that a high level of education (OR: 3.035, 95% CI: 2.310–3.987), high economic status (OR: 6.691, 95% CI: 5.768–7.761), urban residence (OR: 2.947, 95% CI: 2.730–3.181), working status (OR: 0.853, 95% CI: 0.793–0.918), involvement in decision-making (OR: 0.887, 95% CI: 0.804–0.910), and having more than four visits to antenatal care centers (OR: 1.917, 95% CI: 1.783–2.061) were significant determinants of delivery at healthcare facilities. Conclusion. Efforts to improve facility-based childbirth in Indonesia must strengthen initiatives that promote women’s education, women’s autonomy, opportunities for wealth creation, and increased uptake of antenatal care, among others. Any barriers related to maternal healthcare services and cultural factors on the use of health facilities for childbirth in Indonesia require further monitoring and evaluation.
Population boundary across an environmental gradient: Effects of quenched disorder

description: Population boundary is a classic indicator of climatic response in ecology. In addition to known challenges, the spatial and dynamical characteristics of the boundary are not only affected by the spatial gradient in the environmental factors, but also by local heterogeneities in the regional characteristics. Here, we capture the effects of quenched heterogeneities on the ecological boundary with the disordered contact process in one and two dimensions with a linear spatial trend in the local control parameter. We apply the strong-disorder renormalization group method to calculate the sites occupied with an $O(1)$ probability in the stationary state, readily yielding the population front's position as the outermost site locally as well as globally for the entire boundary. We show that under a quasistatic change of the global environment, mimicking climate change, the front advances intermittently: long quiescent periods are interrupted by rare but long jumps. The characteristics of this intermittent dynamics are found to obey universal scaling laws in terms of the gradient, conjectured to be related to the correlation-length exponent of the model. Our results suggest that current observations might misleadingly show little to no climate response for an extended period of time, concealing the long-term effects of climate change.

Symmetric and non-symmetric quantum Capelli polynomials

Publisher: name: arXiv
Year: 1996
Subjects: subject: Quantum Algebra (math.QA)
subject: FOS: Mathematics

description: We define a family of symmetric and a family of non-symmetric polynomials in terms of vanishing conditions. These families depend on two paramters, q and t. Their main feature is that they consist of non-homogeneous polynomials. The symmetric polynomials form the quantized version of polynomials occuring in the context of generalized Capelli identities. We show that these quantum Capelli polynomials are also characterized by q-difference equations. More precisely, they are eigenfunctions of Cherednik type operators and transform under an affine Hecke algebra. Thus, we are able to identify their top homogeneous component as a Macdonald polynomial (symmetric or non-symmetric, respectively).

description: The problem that this study addressed is the rise of internet gaming disorder (IGD) globally, including within the United States and countries such as China—and, the resultant need for more data on the prevalence of adult men and women meeting criteria for a diagnosis of IGD, as well as data on related comorbidities and psychosocial issues. A global sample (N=231) met the study inclusion criteria (i.e., play video games at least once a week at a minimum, consider themselves involved in Internet gaming, and have been gaming for the past six months—while of interest were findings with an English Speaking (ES) sample, and a Chinese Mandarin Speaking (CMS) sample. The study sample of convenience recruited via a social media campaign was 62.4% (n=63) male in the ES sample, and 55.4% (n=72) male in the CMS sample. The ES sample had a mean age of 29.34 (SD=8.396, Min=18, Max=52), and the CMS sample had mean age of 25.65 (SD=7.514, Min=18, Max=57). While the CMS sample indicated they were Asian (99.2%, n=129), the ES sample was diverse: 58% White (n=59), 17.8% (n=59) Asian, and 11.9% (n=12) Black.
      The main study findings reveal a prevalence of Internet Gaming Disorder (IGD of 0% (n=101) for the ES sample, and .8% (n=1) for the CMS sample. As another main study finding, for the CMS sample, participants met more DSM-5 criteria for IGD (out of the 9 total criteria), when they were male, experienced anxiety in the past year, and were engaged in more violence due to gaming. For the ES sample, study participants met more DSM-5 criteria for IGD (out of the 9 total criteria), when they did not have a partner, had a higher income, were engaged in more violence due to gaming, engaged in a higher level of help seeking for personal/emotional support, and had a lower level of perceived social support. In essence, this constitutes the provision of risk profiles and descriptions of those most vulnerable to IGD. This study contributes to those efforts to conduct research on the DSM-5 criteria for IGD (APA, 2013).
