Large Psoas Hematoma Complicating Anti-coagulant Therapy Poses a Diagnostic and Therapeutic Challenge

Spontaneous psoas haematoma in patients on anti-coagulant therapy is a rare phenomenon. It poses a real diagnostic problem and a real therapeutic challenge. We report the case of a 51 year old patient, under anti-vitamin K (acenocoumarone) following a stenosante and tricuspid mitral plasty who presented with right lumbar pain radiating to the lower limb leading to functional impotence. Clinically, he was hemodynamically stable with a hematoma measuring 88x29 mm and extending to 161 mm. The ultrasound scan showed a large collection at the expense of the lumbar psoas muscle and the CT scan showed a swollen appearance of the right psoas muscle in its iliac portion. Management was conservative: discontinuation of anti-vitamin K, bed rest, antibiotic therapy, and monitoring (clinical, biological and radiological). The ultimate outcome was favourable.

Tort Law and Climate Change

Tort law presents doctrinal barriers to plaintiffs seeking remedies for climate change harms in common law jurisdictions. However, litigants are likely to persist in pursuing tortious causes of action in the absence of persuasive policy and regulatory alternatives. Ongoing litigation in Smith v Fonterra Co-operative Group Ltd in New Zealand and Sharma v Minister for Environment in Australia highlights tensions between torts doctrine and climate change litigation in both countries. Regardless of its ultimate outcome, that litigation provides a valuable opportunity to integrate theoretical questions about the legitimacy of judicial lawmaking, and intersectional critical legal perspectives, into the teaching of torts.

Making the Paris Agreement: Historical Processes and the Drivers of Institutional Design

After a decade-long search, countries finally agreed on a new climate treaty in 2015. The Paris Agreement has attracted attention both for overcoming years of gridlock and for its novel features. Here, we build on accounts explaining why states reached agreement, arguing that a deeper understanding requires a focus on institutional design. Ultimately, it was this agreement, with its specific provisions, that proved acceptable to states rather than other possible outcomes. Our account is multi-causal and draws methodological inspiration from the public policy and causes of war literatures. Specifically, we distinguish between background, intermediate, and proximate conditions and identify how they relate to one another, jointly producing the ultimate outcome we observe. Our analysis focuses especially on the role of scientific knowledge, non-state actor mobilization, institutional legacies, bargaining, and coalition-building in the final push for agreement. This case-based approach helps to understand the origins of Paris, but also offers a unique, historically grounded way to examine questions of institutional design.

Capital as an Integrative Conceptualisation of Human Characteristics, Behaviour, and Outcomes Predicting Reproductive Success and Evolutionary Fitness

According to evolutionary theory, human cognition and behaviour are based on adaptations selected for their contribution to reproduction in the past, which in the present may result in differential reproductive success and inclusive fitness. Because this depiction is broad and human behaviour often separated from this ultimate outcome (e.g., increasing childlessness), evolutionary theory can only incompletely account for human everyday behaviour. Moreover, effects of most studied traits and characteristics on mating and reproductive success turned out not to be robust. In this article, an abstract descriptive level for evaluating human characteristics, behaviour, and outcomes is proposed, as a predictor of long-term reproductive success and fitness. Characteristics, behaviour, and outcomes are assessed in terms of attained and maintained capital, defined by more concrete (e.g., mating success, personality traits) and abstract (e.g., influence, received attention) facets, thus extending constructs like embodied capital and social capital theory, which focuses on resources embedded in social relationships. Situations are framed as opportunities to gain capital, and situational factors function as elicitors for gaining and evaluating capital. Combined capital facets should more robustly predict reproductive success and (theoretically) fitness than individual fitness predictors. Different ways of defining and testing these associations are outlined, including a method for empirically examining the psychometric utility of introducing a capital concept. Further theorising and empirical research should more precisely define capital and its facets, and test associations with (correlates of) reproductive success and fitness.

Quality of Life for People with Disabilities: Why Applied Behavior Analysts Should Consider This a Primary Dependent Variable

Applied behavior analysis (ABA) is a natural science dedicated to using behavioral principles to address socially important problems. One area in which behavior analysts have made compelling gains in the last 50 years is in developing, evaluating, and disseminating effective interventions for people with significant intellectual and developmental disabilities. As the science of ABA has matured, many practitioners, researchers, and consumers have questioned how our field should define appropriate outcomes of behavioral interventions. In this article, we propose that improved quality of life should be the ultimate outcome for consumers receiving behavioral interventions. We explore definitions of quality of life and suggest some strategies that behavior analysts can apply to modify practices to more clearly center quality of life as an outcome variable.

Internality and the internalisation of failure: Evidence from a novel task

A critical facet of adjusting one’s behaviour after succeeding or failing at a task is assigning responsibility for the ultimate outcome. Humans have trait- and state-like tendencies to implicate aspects of their own behaviour (called ‘internal’ ascriptions) or facets of the particular task or Lady Luck (’chance’). However, how these tendencies interact with actual performance is unclear. We designed a novel task in which subjects had to learn the likelihood of achieving their goals, and the extent to which this depended on their efforts. High internality (Levenson I-score) was associated with decision making patterns that are less vulnerable to failure. Our computational analyses suggested that this depended heavily on the adjustment in the perceived achievability of riskier goals following failure. We found beliefs about chance not to be explanatory of choice behaviour in our task. Beliefs about powerful others were strong predictors of behaviour, but only when subjects lacked substantial influence over the outcome. Our results provide an evidentiary basis for heuristics and learning differences that underlie the formation and maintenance of control expectations by the self.

The Value of Communication in Agile Project Management

The purpose of this research is to understand the importance and impact of communication in an Agile environment so as to suggest ways to overcome communication challenges in Agile projects. In this research, the latest use of communication methods, approaches, and challenges faced by Agile teams are thoroughly evaluated to know the best solutions to communication problems. A literature review in this study proposes that a lack of proper communication is one of the main challenges faced by Agile projects. The authors used a systematic literature review to examine pre-existing literature and to select the most pertinent literature to assess these variables in depth and to create an assessment model. The ultimate outcome of this study was the development of the best practices that improve communication in Agile project environments.

Are voters' views about proportional outcomes shaped by partisan preferences? A survey experiment in the context of a real election

We examine citizens' evaluations of majoritarian and proportional electoral outcomes through an innovative experimental design. We ask respondents to react to six possible electoral outcomes during the 2019 Canadian federal election campaign. There are two treatments: the performance of the party and the proportionality of electoral outcomes. There are three performance conditions: the preferred party's vote share corresponds to vote intentions as reported in the polls at the time of the survey (the reference), or it gets 6 percentage points more (fewer) votes. There are two electoral outcome conditions: disproportional and proportional. We find that proportional outcomes are slightly preferred and that these preferences are partly conditional on partisan considerations. In the end, however, people focus on the ultimate outcome, that is, who is likely to form the government. People are happy when their party has a plurality of seats and is therefore likely to form the government, and relatively unhappy otherwise. We end with a discussion of the merits and limits of our research design.

Biblical versus Greek Narratives for Suicide Prevention and Life Promotion: Releasing Hope from Pandora’s Urn

Although suicide has been unfortunately stigmatized unfairly through the ages, we should not make the mistake of going to the opposite extreme and valorizing it. We should not forget that the major role of health care professionals is to prevent suicide when possible and to invigorate the underlying life force in the person. Suicide is often the ultimate outcome of a tragic and pessimistic view of life. It was prevalent in ancient Greek writing. Indeed, over 16 suicides and self-mutilations can be found in the 26 surviving tragedies of Sophocles and Euripides. In contrast, only six suicides can be found in the Hebrew Scriptures, and only one suicide in the Christian Scriptures. In addition, the Hebrew Scriptures present numerous suicide-prevention narratives that effectively provide a psychological instruction for people in despair which seems unavailable to figures in the writings of the great Greek tragedians. Unfortunately, some religious traditions tended to go to the opposite extreme in stigmatizing suicide rather than understanding it and trying to prevent it. This paper examines evidence regarding seven evidence-based risk factors for suicide: (1) Feeling depressed and isolated; (2) Feeling one’s life is without purpose; (3) Being a refugee from one’s homeland; (4) Feeling unable to express oneself with others; (5) Being adopted; (6) Feeling abandoned by one’s child leaving the family nest; and (7) Feeling doomed by a dysfunctional (indeed incestuous) family of origin We contrast biblical and Greek narratives regarding each of these factors, respectively: (1) Elijah against Ajax, (2) Job against Zeno, (3) David against Coriolanus, (4) Jonah against Narcissus, (5) Moses against Oedipus, (6) Rebecca against Phaedra, and finally, (7) Ruth against Antigone. These biblical figures thrive across risk factors while their Greek and Roman counterparts kill or mutilate themselves or provoke others to do the job. All these contrasts should demonstrate to psychotherapists, counselors, and clergy alike as to how Greek narratives lead to self-destructive behaviors while biblical narratives provide a hopeful positive psychology, and a constructive way out these dilemmas. My colleagues (Paul Cantz, Matthew Schwartz, and Moriah Markus-Kaplan) and I call for a biblical psychotherapy for positive psychology, suicide prevention, and indeed life promotion. Where hope is locked up in Pandora’s urn after she has released all the evils unto the world, the biblical God places hope into the sky as a bow after Noah and his family and all the creatures on the ark disembark to land after the receding of the flood.

Problem Solving in Animals: Proposal for an Ontogenetic Perspective

Problem solving, the act of overcoming an obstacle to obtain an incentive, has been studied in a wide variety of taxa, and is often based on simple strategies such as trial-and-error learning, instead of higher-order cognitive processes, such as insight. There are large variations in problem solving abilities between species, populations and individuals, and this variation could arise due to differences in development, and other intrinsic (genetic, neuroendocrine and aging) and extrinsic (environmental) factors. However, experimental studies investigating the ontogeny of problem solving are lacking. Here, we provide a comprehensive review of problem solving from an ontogenetic perspective. The focus is to highlight aspects of problem solving that have been overlooked in the current literature, and highlight why developmental influences of problem-solving ability are particularly important avenues for future investigation. We argue that the ultimate outcome of solving a problem is underpinned by interacting cognitive, physiological and behavioural components, all of which are affected by ontogenetic factors. We emphasise that, due to the large number of confounding ontogenetic influences, an individual-centric approach is important for a full understanding of the development of problem solving.
