The phenomenon of size constancy is defined as the apparent perceptual invariance of the linear dimensions of a seen object as this approaches the eye or recedes from it. It has been interpreted as resulting from the application by the brain of a size correction, made possible by the subject's apprehension of distance cues present in the image. We present several observations which, by dissociating accommodation from distance of the seen object and by suppressing the optic effects of accommodation on (...) the visual image itself, show that this interpretation is incorrect, and that in fact the size correction of the visual image is a function of the central effort of accommodation, not of the distance of the seen object.

Grandiose narcissistic traits refer to exploitative and arrogant attitudes, while vulnerable narcissistic traits entail hypersensitivity to judgment and low self-esteem. Little is known about how individuals with narcissistic traits can improve their attitudes toward themselves and others. The current research puts self- and other compassion forward as possible targets to alleviate some of destructive patterns of narcissism. Generally, self-compassion has previously been associated with beneficial effects on psychological wellbeing, while other compassion is advantageous for interpersonal relationships. This study explored the (...) relationship between narcissistic traits and the efficacy of experimental compassion inductions. Student and community participants completed grandiose and vulnerable narcissistic trait, SC and OC state questionnaires, and either an SC or OC induction. It was expected that individuals with higher narcissistic traits would benefit from the inductions and show higher SC after but would have greater difficulty showing meaningful increases in OC. The results indicated that individual differences in grandiose and vulnerable narcissistic traits are related to the magnitude of improvements following the inductions: the theorized lack of SC in individuals with vulnerable oversensitivity to judgment traits seems possible to be counteracted through different types of compassion exercises. Moreover, higher grandiose exploitativeness–entitlement and global vulnerable narcissistic traits related to less increases than others. However, directly inducing OC in individuals with these traits was linked to greater OC improvements than improvements after inducing SC. Overall, the present findings suggest that self-compassionate behavior can be improved in individuals with high oversensitivity and that other compassionate behavior could potentially be increased if, specifically, other compassion exercises are utilized when higher levels of certain narcissistic traits are present.

To understand how compliance develops both in everyday and corporate environments, it is crucial to understand how different mechanisms work together to shape individuals’ (non)compliant behavior. Existing compliance studies typically focus on a subset of theories (i.e., rational choice theories, social theories, legitimacy theories, capacity theories, and opportunity theories) to understand how key variables from one or several of these theories shape individual compliance. The present study provides a first integrated understanding of compliance, rooted in complexity science, in which key (...) elements from these theories are considered simultaneously, and their relations to compliance and each other are explored using network analysis. This approach is developed by analyzing online survey data (_N_ = 562) about compliance with COVID-19 mitigation measures. Traditional regression analysis shows that elements from nearly all major compliance theories (except for social theories) are associated with compliance. The network analysis revealed groupings and interconnections of variables that did not track the existing compliance theories and point to a complexity overlooked in existing compliance research. These findings demonstrate a fundamentally different perspective on compliance, which moves away from traditional narrow, non-network approaches. Instead, they showcase a complexity science understanding of compliance, in which compliance is understood as a network of interacting variables derived from different theories that interact with compliance. This points to a new research agenda that is oriented on mapping compliance networks, and testing and modelling how regulatory and management interventions interact with each other and compliance within such networks.

More instability (MSSD) and variability (SD) of negative affect (NA) have been related to current and future depressive symptoms. We investigated whether NA instability and variability were predictive of the rate of symptom improvement during treatment and of reaching remission status. Forty-six individuals with major depressive disorder completed six days of ecological momentary assessments (10 beeps/day) before starting a combination of pharmacotherapy and supportive therapy. During and after treatment, the Hamilton Depression Rating Scale (HDRS) diagnostic interview was performed monthly for (...) 18 months. The rate of change in HDRS scores over five months (during treatment) and remission status (HDRS ≤ 7) over eighteen months were predicted by the SD, MSSD and Mean of NA, and relevant baseline predictors. Higher Mean NA and baseline symptom severity, but not NA variability or instability, predicted stronger depressive symptom reduction during treatment. Higher odds of remitting were only associated with lower Mean NA. Higher mean NA may indicate more room for improvement and thus for a steeper rate of symptom change, while lower mean NA levels may imply that remission status is more readily reached. To resolve the inconclusive findings for instability and variability as predictors of symptom improvement replication in larger samples is required. (shrink)

Literature on attitude similarity suggests that sharing similar attitudes enhances interpersonal liking, but it remains unanswered whether this effect also holds for ambivalent attitudes. In the present research, we shed light on the role attitudinal ambivalence plays in interpersonal liking. Specifically, we examine whether people express ambivalence strategically to generate a positive or negative social image, and whether this is dependent on the attitudinal ambivalence of their perceiver. We test two alternative hypotheses. In line with the attitude-similarity effect, people should (...) express ambivalence towards ambivalent others to enhance interpersonal liking, as sharing ambivalence might socially validate the latter’s experience of attitudinal conflict. On the other hand, people might express more univalence, as ambivalence may drive ambivalent others towards the resolution of their attitudinal conflict and univalent stances could help to achieve that goal. In two studies (N = 449, 149), people expressed similar attitudes to those of their perceivers, even when the latter experienced attitudinal conflict (Study 1 and 2). Moreover, they composed an essay, the message of which validated their perceiver’s attitudinal conflict (Study 2). In line with these results, we further observe that the more people experienced their ambivalence as conflicting, the more they liked others who similarly experienced attitudinal conflict (Study 1). These findings suggest that the expression of ambivalence can have important interpersonal functions, as it might lead to an enhanced social image when interacting with those coping with attitudinal conflict.

This article assesses which policies for addressing antibiotic resistance as part of a multi-pronged approach would benefit from legalization through an international legal agreement. Ten candidate policies were identified based on a review of existing literature, especially The Lancet Series on Antimicrobial Resistance, The Lancet Infectious Diseases Commission on AMR, and the World Health Organization Global Action Plan for AMR. These policies were then grouped under the headings of access, conservation, and innovation.Each of the ten policies were assessed using four (...) criteria developed by Hoffman, Røttingen, and Frenk to help consider why their legalization may be helpful, necessary and/or justified. These criteria are: the problem has a significant transnational dimension; the goal justifies the coercive nature of law; the outcome is likely to be beneficial; and legalization represents the best commitment mechanism among competing alternatives.

The Crusades are a period of struggle between the East and the West, or between Muslims and Christians, covering nearly two centuries. However, much of the academic research on the Crusades is European-centered and written by experts of the Middle Ages of the West. Changing this viewpoint whose impressions about the Muslim perspective are incomplete and distorted is possible by reconsidering the History of the Crusades from an East / Muslim point of view. In this study, the first reaction of (...) the Muslims against Crusades, the situation of the Seljuk State, the struggles between Frenk and Turks after the seizure of Seljuqan capital İznik by the Crusaders and the collapse of Urfa and Antakya cities will be discussed in the axis of the first Crusade. The sources of the research constitute the chronicles, biographies and geographical studies related to the subject. (shrink)

The Millennium Development Goals were criticised for failing to address the issue of governance, and the associated notions of responsibility and accountability. The Sustainable Development Goals, we argue, need to recognise the structural constraints facing poor countries – the power imbalances in the global economic system that limit their ability to promote the prosperity and well-being of their people, as was clearly brought out by the Commission on Global Governance for Health, of which we were both members [Ottersen, O. P., (...) J. Dasgupta, C. Blouin, Paulo Buss, Virasakdi Chongsuvivatwong, Julio Frenk, Sakiko Fukuda-Parr, et al. 2014. “The Political Origins of Health Inequality: Prospects for Change.” Lancet 383: 630–667]. This article is divided into three parts. We begin by making the case for a global justice perspective which emphasises the responsibility – and hence also accountability – of international organisations and rule-making bodies. We next demonstrate the limitations of accountabi.. (shrink)
