Development and Initial Validation of the Triarchic Model Scales

The term “psychopath” is a word used often, particularly on tv shows, courtroom dramas like Law and Order, and even in everyday language to describe the people we know who may be deviant, cold, and lacking remorse. Although these descriptors may be accurate, they don’t adequately encapsulate the construct of psychopathy entirely. The picture of individuals with actual psychopathy is much more complex, and our field’s history of attempts to parse out psychopathic traits is equally as convoluted, which has led to differences in conceptualization and measurement. Despite the attention paid to the psychopathy construct, a full conceptualization of psychopathy is not exclusively listed in the most updated edition of our diagnostic manual, the DSM-5-TR, and is instead placed in Section III under the Alternative Model of Personality Disorder category. Based on Patrick et al. (2009), the current research aims to improve the ability to characterize psychopathy by creating scales of triarchic psychopathy by utilizing the CAT-PD, a self-report measure of the DSM-5 personality traits

Two-step solid-state synthesis of PEPPSI-type compounds

peer-reviewedThe two-step mechanochemical preparation of carbene–pyridine complexes of palladium and platinum is reported. The organometallic products, which represent a class of commercially available catalysts, are rapidly formed in excellent yield proving solvent-free synthesis to be a viable synthetic alternative even in the case of NHC-containing compounds

Old Pioneer\u27s Reminiscenses of Illawarra

Who was Old Pioneer? Despite the passing of over sixty years since the initial publication of the series Reminiscences of Illawana by Old Pioneer in the Illawarra Mercury between 1923-25, the identity of this Old Pioneer is still shrouded in mystery. It is commonly held that Old Pioneer was Frank Young, a prominent local resident and journalist with the Illawarra Mercury, who used letters written to that paper by various old pioneers of Illawarra - including William Piper (1843-1927) - along with his own personal interview material and reminiscences, to compile the series known as Reminiscences of Illawarra by Old Pioneer . This series was published in the Illawarra Mercury in 79 parts between 12 October 1923 and 8 May 1925, and a further, un-numbered part appeared on 8 June 1934.https://ro.uow.edu.au/hcp/1005/thumbnail.jp

Investigating Student Perceptions of a Dissection‐Based Undergraduate Gross Anatomy Course Using Q Methodology

The demand for upper‐level undergraduate dissection‐based anatomy courses is growing, as professional programs require more advanced anatomy training prior to matriculation. To address this need, Indiana University School of Medicine (IUSM) partnered with Indiana University‐Purdue University Indianapolis—a large, urban, life science‐focused campus nearby to IUSM—to offer an undergraduate, dissection‐based course in regional gross anatomy. Because this is a new course, a deeper post‐course evaluation of student perceptions was conducted using Q methodology. In this study, Q methodology was used to evaluate student views of the overall course structure, pre‐laboratory materials and activities, assessments, and quality of instruction. Of the 15 students in the spring semester 2018 cohort, 80% (n = 12) participated in the evaluation, and 10 of those students followed up with written explanations for their rationale in selecting the four statements with which they most strongly agreed and disagreed. The Q methodology sorted the students into one of three statistically significant groups: Motivated Dissectors (n = 6), Traditional Students (n = 3), and Inspired Learners (n = 3). Motivated Dissectors and Inspired Learners felt strongly that the course did not encourage self‐directed learning and that the pre‐laboratory materials were not adequate to prepare them for quizzes. Traditional Students, however, disagreed, having a favorable opinion of the pre‐laboratory materials, even though this group felt most strongly that the amount of material covered in the course was overwhelming. This study demonstrates the utility of Q methodology to evaluate courses to elucidate student perspectives and inform future course modifications

Caudal Vertebral Body Articular Surface Morphology Correlates with Functional Tail Use in Anthropoid Primates

Prehensile tails, capable of suspending the entire body weight of an animal, have evolved in parallel in New World monkeys (Platyrrhini): once in the Atelinae (Alouatta, Ateles, Brachyteles, Lagothrix), and once in the Cebinae (Cebus, Sapajus). Structurally, the prehensile tails of atelines and cebines share morphological features that distinguish them from non-prehensile tails, including longer proximal tail regions, well-developed hemal processes, robust caudal vertebrae resistant to higher torsional and bending stresses, and caudal musculature capable of producing higher contractile forces. The functional significance of shape variation in the articular surfaces of caudal vertebral bodies, however, is relatively less well understood. Given that tail use differs considerably among prehensile and non-prehensile anthropoids, it is reasonable to predict that caudal vertebral body articular surface area and shape will respond to use-specific patterns of mechanical loading. We examine the potential for intervertebral articular surface contour curvature and relative surface area to discriminate between prehensile- and nonprehensile-tailed platyrrhines and cercopithecoids. The proximal and distal intervertebral articular surfaces of the first (Ca1), transitional (TV) and longest (LV) caudal vertebrae were examined for individuals representing 10 anthropoid taxa with differential patterns of tail-use. Study results reveal significant morphological differences consistent with the functional demands of unique patterns of tail use for all vertebral elements sampled. Prehensile-tailed platyrrhines that more frequently use their tails in suspension (atelines) had significantly larger and more convex intervertebral articular surfaces than all nonprehensile-tailed anthropoids examined here, although the intervertebral articular surface contour curvatures of large, terrestrial cercopithecoids (i.e. Papio) converge on the ateline condition. Prehensile-tailed platyrrhines that more often use their tails in tripodal bracing postures (cebines) are morphologically intermediate between atelines and nonprehensile tailed anthropoids.The authors would like to thank Bill Stanley, the Field Museum and the University of Texas at Austin for access to specimens and curatorial assistance as well as the Louisville Zoo and Dr. Roy Burns for their generous donation of Lagothrix lagotricha cadavers.

Toward an Understanding of Beaver Management as Human and Beaver Densities Increase

Estimates of beaver (Castor canadensis) density play an important role in wildlife managers’ decisions about beaver population management, because managers anticipate higher incidence of problem complaints when a beaver population increases. To manage the impacts of beavers in an urbanizing landscape, managers need better information on changes in stakeholder beliefs and attitudes as beaver and human densities reach high levels. We conducted additional analysis of data collected in 2002 through mail surveys of residents in New York and Massachusetts to test hypothesized relationships between beaver density and damage experience, attitudes toward beavers, and norms about beaver management actions. Consistent with previous research, we found a correlation between personal experience with beaver-related problems, lower acceptance capacity for beavers, and higher acceptability of lethal beaver management actions. In comparison to residents living in areas with low beaver density, residents of areas with high beaver density were more likely to: experience beaver-related problems; believe that beaver-related damage had greatly increased in their area; express a preference for beaver population reduction; express less tolerant attitudes toward beaver presence; and accept lethal control of beavers as a response to beaver-related problems. These findings add to understanding of wildlife acceptance capacity, generally, and tolerance of beavers specifically. Based on our findings, we propose a conceptual model representing key dynamic interrelationships between stakeholder attitudes, norms, and common beaver management practices. We discuss a causal loop diagram representing the model to illuminate the challenges wildlife managers are likely to face as the context for beaver management changes. The model articulates the dynamic complexity of urban beaver management and fills a gap in the literature by conceptualizing beaver management as a coupled human–natural system. Such models may aid communication in locales where high densities of beaver and people set the stage for human–wildlife conflict and emergence of disruptive wildlife management issues
