description: While prior hospitality and tourism research has shown interest in the impact of tourism on destination sustainability and residents’ perceptions, it remains unclear how these changes could affect residents’ attitudes toward hospitality employment. This study explores the relationship between residents’ attitudes to the negative impact of tourism and their willingness to work in the hospitality industry under the mediation effect of residents’ emotional exhaustion and psychological well-being. Furthermore, the boundary condition of residents’ destination management perceptions was also explored between attitudes to the negative impact of tourism and the aforementioned mediators. Results obtained through an online survey showed that while the influence between residents’ attitudes to the negative impact of tourism on their willingness to work in the hospitality industry is identified, emotional exhaustion and psychological well-being were not significant mediators. Moreover, the boundary condition of residents’ destination management perceptions was not shown to be a significant moderator when exploring residents’ attitudes to the negative impact of tourism on both emotional exhaustion and psychological well-being. Only residents’ psychological well-being was shown to significantly reduce residents’ willingness to work in the hospitality industry when negatively influenced.

description: Webly supervised learning becomes attractive recently for its efficiency in data expansion without expensive human labeling. However, adopting search queries or hashtags as web labels of images for training brings massive noise that degrades the performance of DNNs. Especially, due to the semantic confusion of query words, the images retrieved by one query may contain tremendous images belonging to other concepts. For example, searching `tiger cat' on Flickr will return a dominating number of tiger images rather than the cat images. These realistic noisy samples usually have clear visual semantic clusters in the visual space that mislead DNNs from learning accurate semantic labels. To correct real-world noisy labels, expensive human annotations seem indispensable. Fortunately, we find that metadata can provide extra knowledge to discover clean web labels in a labor-free fashion, making it feasible to automatically provide correct semantic guidance among the massive label-noisy web data. In this paper, we propose an automatic label corrector VSGraph-LC based on the visual-semantic graph. VSGraph-LC starts from anchor selection referring to the semantic similarity between metadata and correct label concepts, and then propagates correct labels from anchors on a visual graph using graph neural network (GNN). Experiments on realistic webly supervised learning datasets Webvision-1000 and NUS-81-Web show the effectiveness and robustness of VSGraph-LC. Moreover, VSGraph-LC reveals its advantage on the open-set validation set.

The constraint on the spin dependent structure function $g_1$ at low $Q^2$ through the sum rule corresponding to the moment at $n=0$

description: The sum rules for the spin dependent structure function $g_1^{ab}$ in the null-plane formalism corresponding to the moment at $n=0$ has been transformed to the sum rule which relates the $g_1^{ab}$ with the cross section of the isovector photon or the real photon. Based on these sum rules, we argue that there is a deep connection among the elastic, the resonance, and the non-resonant contributions, and that it explains why the sign of the generalized Gerasimov-Drell-Hearn sum changes at very small $Q^2$.

description: Developing accurate models of crop stress, phenology and productivity is of paramount importance, given the increasing need of food. Earth observation remote sensing data provides a unique source of information to monitor crops in a temporally resolved and spatially explicit way. In this study, we propose the combination of multisensor (optical and microwave) remote sensing data for crop yield estimation and forecasting using two novel approaches. We first propose the lag between Enhanced Vegetation Index derived from MODIS and Vegetation Optical Depth derived from SMAP as a new joint metric combining the information from the two satellite sensors in a unique feature or descriptor. Our second approach avoids summarizing statistics and uses machine learning to combine full time series of EVI and VOD. This study considers two statistical methods, a regularized linear regression and its nonlinear extension called kernel ridge regression to directly estimate the county-level surveyed total production, as well as individual yields of the major crops grown in the region: corn, soybean and wheat. The study area includes the US Corn Belt, and we use agricultural survey data from the National Agricultural Statistics Service (USDA-NASS) for year 2015 for quantitative assessment.

description: We image equilibrium and non-equilibrium transport through a two-dimensional electronic cavity using scanning gate microscopy (SGM). Injecting electrons into the cavity through a quantum point contact close to equilibrium, we raster-scan a weakly invasive tip above the cavity regions and measure the modulated conductance through the cavity. Varying the electron injection energy between $\pm$ 2 meV, we observe that conductance minima turn into maxima beyond the energy threshold of $\pm$ 0.6 meV. This observation bears similarity to previous measurements by Jura et al. [Jura et al., Phys. Rev. B 82, 155328 (2010)] who used a strongly invasive tip potential to study electron injection into an open two-dimensional electron gas. This resemblance suggests a similar microscopic origin based on electron-electron interactions.

description: This study reports on photometric results of a search for LSB galaxies in a 0.76deg^2 field centered on the HDF-S. We present results from photometric analysis of the derived sample galaxies and compare number densities to results of former surveys. We used public data from the NOAO Deep Wide-Field survey and the multi-wavelength Goddard Space Flight Center survey. The former reaches a limiting surface brightness of mu_BW~29 magarcsec^-2 and is therefore one of the most sensitive ground based data sets systematically analyzed for LSB galaxies. To reduce the contamination by High Surface Brightness (HSB) galaxies at higher redshift, mimicking LSBs due to the ''Tolman Dimming'' effect, we placed a lower diameter limit of 10.8 arcsec and compared the colors of our candidate galaxies with the redshift tracks of 5 ''standard'' HSB galaxy types. We report the detection of 37 galaxies with low apparent central surface brightness (mu_BW>=22 magarcsec^-2). Using color-color diagrams we were able to derive a subsample of 9 LSB galaxy candidates with intrinsic central surface brightnesses below mu_(0,BW)=22.5 magarcsec^-2 and diameters larger than the preselected size limit of 10.8 arcsec. We selected three additional LSB candidates due to there extreme low blue central surface brightness (mu_BW>=25 magarcsec^-2). These galaxies were only found in the larger and more sensitive NOAO data. So finally we derived a sample of 12 LSB galaxy candidates and therfore this survey results in a four times higher surface density than other CCD based surveys for field galaxies before.

description: This thesis examines the formation of a region that can be called the Great Plains Midwest. It shows this formation through the city of Emporia, Kansas, which grew in tandem with the region. The thesis also examines Emporia as a case study of the cycle of birth, growth, and stagnation visible across the Great Plains between the 1850s and 1910s. This era traces Emporia from its humble beginnings to a period of population stagnation that followed the Panic of 1893. Three chapters cover Emporia’s agriculture, railroads, and colleges and universities, comparing each to the same elsewhere in both the midwestern and western portions of the Great Plains. An epilogue reflects on Emporia’s legacy from the late nineteenth and early twentieth century and the rise of the Great Plains Midwest. The thesis argues that history, geography, and human-development rather than political or state boundaries, played the largest roles in creating distinctions between the midwestern and western portions of the Great Plains.

description: We estimated the dynamical masses of 115 early-type galaxies (ETGs) by analyzing the dynamics of satellite and companion galaxies of these ETGs. We selected galaxies with absolute magnitudes between -22 and -25 in the $K_s$-band from the Extragalactic Distance Database (EDD). We also selected 216 spiral galaxies for comparison. We employed a simple model to simulate the observed dynamical mass from satellite galaxies at various distances. Our simulations showed that the dynamical masses derived from satellite galaxies with elliptical orbits would be smaller than those with circular orbits even they contain the same dark mass halos. Therefore, relationships between the observed $M_\mathrm{dyn}/M_\mathrm{b}$ distributions and distances would depend on orbital shapes. From the relationships between our observed $M_\mathrm{dyn}/M_\mathrm{b}$ distributions and distances, we suggest that the satellite galaxies of the ETGs have relatively more elliptical orbits than those of the spiral galaxies have and the $M_\mathrm{dyn}/M_\mathrm{b}$ of the ETGs are greater than that of the spiral galaxies.

description: Networks of living neurons exhibit an avalanche mode of activity, experimentally found in organotypic cultures. Here we present a model based on self-organized criticality and taking into account brain plasticity, which is able to reproduce the spectrum of electroencephalograms (EEG). The model consists in an electrical network with threshold firing and activity-dependent synapse strenghts. The system exhibits an avalanche activity power law distributed. The analysis of the power spectra of the electrical signal reproduces very robustly the power law behaviour with the exponent 0.8, experimentally measured in EEG spectra. The same value of the exponent is found on small-world lattices and for leaky neurons, indicating that universality holds for a wide class of brain models.

description: The nature of ultraluminous X-ray sources (ULXs) is not yet fully understood but it can be done in the most efficient way by analyzing its optical emission and environment. We present preliminary results of photometric and spectral studies of some newly identified ULX optical counterparts. Based on the X-ray catalog of ULX candidates by Liu 2011 we have unequivocally identified in the optical range more than 100 sources, for 49 of them we carried out a long slit spectroscopy. According to these results, the majority of the most brightest candidates (m$_V < 22^m$) turned out to be background objects of different types, but the observed parameters of other sources of the sample allow us to classify them as real ULX. Here we present results for ten selected sources.

description: In the small $Q^2$ region, the sum rule for the polarized structure function $g_2$ corresponding to the moment at $n=0$ is derived. This sum rule shows that there is a tight connection among the resonances,the elastic and the continuum in the $g_2$. Further, the Born term contribution in this sum rule is proportional to $Q^2$ and very small compared with that in the corresponding sum rule for the polarized structure function $g_1$. However, the Born term contribution divided by $Q^2/2$ which also appears in the Schwinger sum rule for the $g_2$ corresponding to the moment at $n=1$ has a very similar behavior with that in the sum rule for the $g_1$ corresponding to the moment at $n=0$.

description: In the present paper, we investigate the blow-up dynamics for local solutions to the semilinear generalized Tricomi equation with combined nonlinearity. As a result, we enlarge the blow-up region in comparison to the ones for the corresponding semilinear models with either power nonlinearity or nonlinearity of derivative type. Our approach is based on an iteration argument to establish lower bound estimates for the space average of local solutions. Finally, we obtain upper bound estimates for the lifespan of local solutions as byproduct of our iteration argument.

This thesis is a reflection on the creation, cultivation, process and performance of Megan Morse Jans' original work Not Leading Lady Material, an interdisciplinary dance-theater piece presented in a style evocative of the cabarets of the Weimar Republic.  The performance included song, storytelling and dance, and thematically explored intimacy, identity, and social/political disruption all while eliminating the fourth wall and inviting the audience on a journey through personal narrative.  This paper examines the navigation and weaving together of different expressive disciplines, as well as the challenges presented in the performance of both original and copyrighted material.  The result was a dynamic performance that engaged the audience in an evening of laughter, participation, and vulnerability.

description: In this interview, Thomas E. Cooney J.D. reflects with great humor upon his childhood, law career, and the direction of medical-legal challenges. He graduated from the University of Portland (B.A. in Philosophy) and Willamette University (J.D.). After graduation, Cooney was admitted to the Oregon bar in 1956. Cooney was a founding member of the Oregon Association of Defense Counsel. He specialized in insurance defense, focusing primarily on complex litigation in medical malpractice defense, professional liability, and health law. Beginning in 1972, he served as general counsel for the Oregon Medical Association. In this interview, he discusses the tremendous changes he has seen in the field and what he expects the future will hold. Additionally, he authored the first Oregon Medical-Legal handbook for physicians, commonly called the "Cheerios Book."
Women, low income, and health : an ethnography of a housing co-operative
Creators: name: Wasylishyn, Christine
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to describe the health beliefs, values, concerns, and health practices of women living on low income in a specific housing co-operative. The choice of this context controlled for some of the diversity which exists amongst poor women. The effect of a co-operative housing environment on the health of these women was also examined. Initially, an ethnographic method was proposed. When access for participant-observation was denied, the method was modified to include intensive interviews only. Ten volunteers were recruited out of the total population of thirty-six women. These women were interviewed individually (with one exception), using an unstructured format. The interviews were audio-taped, transcribed, and analyzed for common themes. At the time of the study, the participants saw themselves as a diverse group lacking a common identity. They did acknowledge, however, that they shared a common history of "hard experiences." The findings revealed that, for these women, inherent in the experience of living on a low income is a sense of a lack of control. Limited finances result in fewer choices and decreased feelings of control over one's life. Consequently, health was defined for these women in terms of meeting basic needs such as safety and security. The participants identified their new environment as having both positive and negative health consequences. Acquiring stable, subsidized housing had reduced, although not eliminated, the stress of coping with limited finances. Initially, however, the new responsibilities associated with managing the co-operative, combined with adjusting to a community lifestyle, provided enough added stress that several women identified a significant deterioration in their health following the move. Since no research could be found which addresses the health of mature, unattached, low income women, this descriptive study represents a starting point for further research.

We show that the system admits a unique weak solution provided the nonlinear adsorption isotherm associated with the reaction process satisfies certain physically reasonable structural conditions. We conclude, moreover, that the solute concentrations stay non-negative if the source term is componentwise non-negative and investigate numerically the finite speed of propagation of compactly supported initial concentrations, in a two-component test case.

description: While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation dynamics of local denaturation bubbles by single molecule spectroscopy. The dynamical opening of DNA bubbles (DNA breathing) is supposedly crucial for biological functioning during, for instance, transcription initiation and DNA's interaction with selectively single-stranded DNA binding proteins. Motivated by this, we consider the bubble breathing dynamics in a heteropolymer DNA based on a (2+1)-variable master equation and complementary stochastic Gillespie simulations, providing the bubble size and the position of the bubble along the sequence as a function of time. We utilize new experimental data that independently obtain stacking and hydrogen bonding contributions to DNA stability. We calculate the spectrum of relaxation times and the experimentally measurable autocorrelation function of a fluorophore-quencher tagged base-pair, and demonstrate good agreement with fluorescence correlation experiments. A significant dependence of opening probability and waiting time between bubble events on the local DNA sequence is revealed and quantified for a promoter sequence of the T7 phage. The strong dependence on sequence, temperature and salt concentration for the breathing dynamics of DNA found here points at a good potential for nanosensing applications by utilizing short fluorophore-quencher dressed DNA constructs.

description: Fusion energy is often regarded as a long-term solution to the world's energy needs. However, even after solving the critical research challenges, engineering and materials science will still impose significant constraints on the characteristics of a fusion power plant. Meanwhile, the global energy grid must transition to low-carbon sources by 2050 to prevent the worst effects of climate change. We review three factors affecting fusion's future trajectory: (1) the significant drop in the price of renewable energy, (2) the intermittency of renewable sources and implications for future energy grids, and (3) the recent proposition of intermediate-level nuclear waste as a product of fusion. Within the scenario assumed by our premises, we find that while there remains a clear motivation to develop fusion power plants, this motivation is likely weakened by the time they become available. We also conclude that most current fusion reactor designs do not take these factors into account and, to increase market penetration, fusion research should consider relaxed nuclear waste design criteria, raw material availability constraints and load-following designs with pulsed operation.

We show that spin-lattice relaxation in this compound is driven by two contributions, namely by interactions of nuclear spins with thermally activated carriers and with localized electron spins. The latter mechanism dominates at lower temperature; at that, our measurements provide striking manifestation of the spin-diffusion-limited relaxation regime. The experimental data obtained allow us to estimate the spin diffusion coefficient.

A Simple and Accurate Riemann Solver for Isothermal MHD

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A new approximate Riemann solver for the equations of magnetohydrodynamics (MHD) with an isothermal equation of state is presented. The proposed method of solution draws on the recent work of Miyoshi and Kusano, in the context of adiabatic MHD, where an approximate solution to the Riemann problem is sought in terms of an average constant velocity and total pressure across the Riemann fan. This allows the formation of four intermediate states enclosed by two outermost fast discontinuities and separated by two rotational waves and an entropy mode. In the present work, a corresponding derivation for the isothermal MHD equations is presented. It is found that the absence of the entropy mode leads to a different formulation which is based on a three-state representation rather than four. Numerical tests in one and two dimensions demonstrates that the new solver is robust and comparable in accuracy to the more expensive linearized solver of Roe, although considerably faster.

The data records are analysed with commutable statistical methods, including R Studio, Bibliometrix package, and the Web of Science data mining tool. We identified few different clusters, containing references to exercise, inflammation, smoking, obesity and many additional factors. From the analysis on Covid-19 and vaccine, we discovered that although the USA is leading in volume of scientific research on Covid 19 vaccine, the leading 3 research institutions (Fudan, Melbourne, Oxford) are not based in the USA. Hence, it is difficult to predict which country would be first to produce a Covid 19 vaccine.

description: In this paper, the Weierstrass technique for harmonic maps S^2 -> CP^(N-1) is employed in order to obtain surfaces immersed in multidimensional Euclidean spaces. It is shown that if the CP^(N-1) model equations are defined on the sphere S^2 and the associated action functional of this model is finite, then the generalized Weierstrass formula for immersion describes conformally parametrized surfaces in the su(N) algebra. In particular, for any holomorphic or antiholomorphic solution of this model the associated surface can be expressed in terms of an orthogonal projector of rank (N-1). The implementation of this method is presented for two-dimensional conformally parametrized surfaces immersed in the su(3) algebra. The usefulness of the proposed approach is illustrated with examples, including the dilation-invariant meron-type solutions and the Veronese solutions for the CP^2 model. Depending on the location of the critical points (zeros and poles) of the first fundamental form associated with the meron solution, it is shown that the associated surfaces are semi-infinite cylinders. It is also demonstrated that surfaces related to holomorphic and mixed Veronese solutions are immersed in R^8 and R^3, respectively.

Correlation lengths for random polymer models and for some renewal sequences

Publisher: name: arXiv

Subjects: subject: Probability (math.PR)

description: We consider models of directed polymers interacting with a one-dimensional defect line on which random charges are placed. More abstractly, one starts from renewal sequence on $\Z$ and gives a random (site-dependent) reward or penalty to the occurrence of a renewal at any given point of $\mathbb Z$. These models are known to undergo a delocalization-localization transition, and the free energy $\tf$ vanishes when the critical point is approached from the localized region. We prove that the quenched correlation length $ξ$, defined as the inverse of the rate of exponential decay of the two-point function, does not diverge faster than $ 1/\tf$. We prove also an exponentially decaying upper bound for the disorder-averaged two-point function, with a good control of the sub-exponential prefactor. We discuss how, in the particular case where disorder is absent, this result can be seen as a refinement of the classical renewal theorem, for a specific class of renewal sequences.

description: Long-lived radioactive nuclides, such as $^{40}$K, $^{232}$Th, $^{235}$U and $^{238}$U, contribute to persistent heat production in the mantle of terrestrial-type planets. As refractory elements, the concentrations of Th and U in a terrestrial exoplanet are implicitly reflected in the photospheric abundances in the stellar host. However, a robust determination of these stellar abundances is difficult in practice owing to the general paucity and weakness of the relevant spectral features. We draw attention to the refractory, $r-$process element europium, which may be used as a convenient and practical proxy for the population analysis of radiogenic heating in exoplanetary systems. As a case study, we present a determination of Eu abundances in the photospheres of $α$ Cen A and B. We find that europium is depleted with respect to iron by $\sim$ 0.1 dex and to silicon by $\sim$ 0.15 dex compared to solar in both binary components. To first order, the measured Eu abundances can be converted to the abundances of $^{232}$Th, $^{235}$U and $^{238}$U with observational constraints while the abundance of $^{40}$K is approximated independently with a Galactic chemical evolution model. We find that the radiogenic heat budget in an $α$-Cen-Earth is $73.4^{+8.3}_{-6.9}$ TW upon its formation and $8.8^{+1.7}_{-1.3}$ TW at the present day, respectively $23\pm5$ % and $54\pm5$ % lower than that in the Hadean and modern Earth. As a consequence, mantle convection in an $α$-Cen-Earth is expected to be overall weaker than that of the Earth (assuming other conditions are the same) and thus such a planet would be less geologically active, suppressing its long-term potential to recycle its crust and volatiles. With Eu abundances being available for a large sample of Sun-like stars, the proposed approach can extend our ability to make predictions about the nature of other rocky worlds.

Distribution. In many countries of Europe, where it has an affinity for salt marshes. New record for the Maltese Islands.
Comments. Each locality encompassed more than one habitat and the sampling area extended along the length of the watercourse where this occurred, and on any accessible adjacent slopes (generally by several hundred square metres) to include garigue, maquis and steppic habitats wherever these occurred.
Some localities not listed in Table 1: The localities of Balzan and Rabat without further localisation are suburban gardens. Wied il-Mistra is a valley with maquis vegetation west of Mistra that leads to Mistra (locality 2). Tal-Hzejjen is a specific part of the valley Wied Ghajn Rihana (locality 11) near its source; Zebbieh is a village where this valley starts. Marfa Ridge is the whole area north of Ghadira (locality 22). Gharb is a village where the valley Wied il-Mielah (locality 28) starts.
1 Surface water available for long periods, i.e. more than just a few days after rain.
2 More sites have been visited, and more frequently than there are records for Dolichopodidae.
3 “Wied” is the Maltese word for valley or watercourse; it is given here to associate this type of habitat with the locality data for the species.

description: Effects of the choice of the freeze-out hypersurface and resonance decays on the HBT interferometry in relativistic heavy-ion collisions are studied in detail within a class of models with single freeze-out. The Monte-Carlo method, as implemented in THERMINATOR, is used to generate hadronic events describing production of particles from a thermalized and expanding source. All well-established hadronic resonances are included in the analysis as their role is crucial at large freeze-out temperatures. We use the two-particle method to extract the correlation functions, which allows us to study the Coulomb effects. We find that the pion HBT data from RHIC are fully compatible with the single freeze-out scenario, pointing at the shape of the freeze-out hypersurface where the transverse radius is decreasing with time. Results for the single-particle spectra for this situation are also presented. Finally, we present predictions for the kaon femtoscopy.

description: In this work we evaluate multi-output (MO) Gaussian Process (GP) models based on the linear model of coregionalization (LMC) for estimation of biophysical parameter variables under a gap filling setup. In particular, we focus on LAI and fAPAR over rice areas. We show how this problem cannot be solved with standard single-output (SO) GP models, and how the proposed MO-GP models are able to successfully predict these variables even in high missing data regimes, by implicitly performing an across-domain information transfer.

Administration Without Consideration: Public Administration’s Oversight of Children

Subjects: public administration, children

description: American children regularly encounter government through routine interactions with public administrators. Because of the unique nature of working with children, these interactions differ from those with adults. Although the public administration literature focuses on implementation of public policy and interactions between citizens and government, few studies contemplate children as different from adults in the administrative context and thus inform the interactions between public administrators and children. As a result, there is an absence of basic understanding of children within the context of public administration—who they are, how they think, what they need. This oversight generates a theoretical shortcoming, as well as real consequences for children.
Variable Selection in Presence of Strong Collinearity with Application to Environmental Mixtures

description: Variable selection has become an essential element of high dimensional statistical modeling to yield parsimonious models while keeping high prediction accuracy. High dimensionality often induces collinearity problems. For instance, studies of environmental mixtures include a large number of pollutants that are strongly inter-correlated. Regularized variable selection methods such as LASSO are popular for statistical variable selection, however, these methods often do not perform well in presence of strong collinearity in terms of selection and prediction. To address these challenges a novel method, namely COrrelation LeaRNing for variable Selection (COLRNS), is developed that is based on iterative correlation learning for cluster detection and variable selection. The COLRNS is further extended to COLRNS Generalized Linear Model (COLRNS-GLM) to be applicable in a generalized linear regression setting. The performance of the methods is evaluated through an extensive set of simulations and real-world applications to environmental mixtures data. The results show that the methods effectively identify a set of influential predictors, improve prediction accuracy, and reduce error in parameter estimation in most simulation scenarios and data applications under strong collinearity in high dimensional data.

description: We uncover a novel and robust phenomenon that causes the gradual self-replication of spatiotemporal Kerr cavity patterns in cylindrical microresonators. These patterns are inherently synchronised multi-frequency combs. Under proper conditions, the axially-localized nature of the patterns leads to a fundamental drift instability that induces transitions amongst patterns with a different number of rows. Self-replications, thus, result in the stepwise addition or removal of individual combs along the cylinder's axis. Transitions occur in a fully reversible and, consequently, deterministic way. The phenomenon puts forward a novel paradigm for Kerr frequency comb formation and reveals important insights into the physics of multi-dimensional nonlinear patterns.

Psychopathy and juvenile homicide
Creators: name: Willoughby, Todd Vincent
Publisher: name: University of British Columbia

description: The study of the phenomena of juvenile homicide has led some researchers to hypothesize the existence of two types of juvenile murderers. The personality and behavioural traits of the first type resemble the characteristics of the psychopath, whereas traits of the second type resemble the characteristics of the nonpsychopath. The current study was designed to assess the strength of the relationship between psychopathy and behavioural/criminological variables related to homicidal behaviour. Psychopathy was measured by the Hare Psychopathy Checklist - Revised (PCL-R), and homicidal variables involved the Cornell Coding Guide for Instrumental versus Hostile/Reactive Aggression and a variable list (e.g., demographics, psychiatric history, index offense details, institutional misbehaviour). Subjects were 41 male and 3 female juvenile murderers (mean age of 16.3 years) who received psychiatric assessments at Youth Forensic Psychiatric Service between 1986 and 1994. Results indicated that the prevalence of psychopathy in the current sample was similar to the prevalence of psychopathy in other studies using juvenile offenders. Psychopathy was not significantly associated with an instrumental style of aggression, suggesting that juvenile psychopaths do not use a planful, cold blooded approach to homicidal violence. Both psychopaths and nonpsychopaths predominantly victimized strangers or acquaintances which may be explained by the socialization styles of juveniles. Nonpsychopaths were more likely to be drunk prior to the index offense and use a weapon during the homicidal event, whereas psychopaths were more likely to kill their victims by brute physical force (i.e., beating and kicking). Although both psychopaths and nonpsychopaths experienced emotional/physiological arousal during the incident, nonpsychopaths were more likely to experience arousal in connection with intoxication whereas psychopaths experienced arousal in connection with a perceived threat from the victim. Psychopathy was associated with greater misbehaviour in juvenile institutions but not adult institutions, which may mean psychopathic young offenders are either intimidated by adult inmates or they ally themselves with powerful inmates in order to escape institutional repercussions for misbehaviour.
