Re-thinking resuscitation: leaving blood pressure cosmetics behind and moving forward to permissive hypotension and a tissue perfusion-based approach

Definitions of shock and resuscitation endpoints traditionally focus on blood pressures and cardiac output. This carries a high risk of overemphasizing systemic hemodynamics at the cost of tissue perfusion. In line with novel shock definitions and evidence of the lack of a correlation between macro- and microcirculation in shock, we recommend that macrocirculatory resuscitation endpoints, particularly arterial and central venous pressure as well as cardiac output, be reconsidered. In this viewpoint article, we propose a three-step approach of resuscitation endpoints in shock of all origins. This approach targets only a minimum individual and context-sensitive mean arterial blood pressure (for example, 45 to 50 mm Hg) to preserve heart and brain perfusion. Further resuscitation is exclusively guided by endpoints of tissue perfusion irrespectively of the presence of arterial hypotension ('permissive hypotension'). Finally, optimization of individual tissue (for example, renal) perfusion is targeted. Prospective clinical studies are necessary to confirm the postulated benefits of targeting these resuscitation endpoints.

Analytical thinking under distrust - better not to know that one distrusts

It is widely known that people utter an untruth from time to time. Our ability to detect and recognize deception and lies and, in the next step, to respond appropriately is not very far-reaching. We were interested in finding out if distrust triggers non-routine, analytical thought processes and therefore improves the detection of lies without dismissing the truth. We conducted two experiments to investigate the influence of an unconscious form of distrust on our thought processes. In the first experiment, participants had to determine whether a report is truthful or false. The aim of this second experiment was to investigate if this enhanced ability to detect a falsified report correctly is based on analytical thinking taking place. To examine our assumptions, we applied the paradigm of belief bias. The results of the second experiments strongly point out the fact that an unconscious form of distrust triggers and fosters analytical thinking.

“Facebook Style”: The Use of Emoticons and Graphic Signs by Users in the Cape Flats

Over the last few years Facebook has become a widespread and continuously expanding medium of communication in Africa and worldwide. Being a new medium of social interaction, Facebook produces its own communication style. It is a style conditioned by the medium and the community of users. My focus of analysis is how Facebook users from the city of Cape Town create this style by means of emoticons and other graphic signs in order to reflect the reality of living in Cape Town’s underprivileged areas. This study is based on a theoretical framework which combines sociolinguistics with Computer-Mediated-Communication to study the emergence of a style peculiar of the online social networks. In a corpus of Coloured Facebook users from the Cape Flats, I have analysed the emergence of emoticons and other graphic signs related to Capetonian gang culture and then tracked the spread of these features to the extensive use by users not related to gangs. It can be deduced that in this process the analysed features amplify their meaning and are employed in a much broader context as their original use. Due to the development and spread of these features we can consider the peculiar electronic communication of Facebook as a style constrained by the electronic medium and its users. It is a style which serves the users to create social meaning and to express their linguistic identities.

Can you see me thinking (about my answers)? Using eye-tracking to illuminate developmental differences in monitoring and control skills and their relation to performance

This study focuses on relations between 7- and 9-year-old children’s and adults’ metacognitive monitoring and control processes. In addition to explicit confidence judgments (CJ), data for participants’ control behavior during learning and recall as well as implicit CJs were collected with an eye-tracking device (Tobii 1750). Results revealed developmental progression in both accuracy of implicit and explicit monitoring across age groups. In addition, efficiency of learning and recall strategies increases with age, as older participants allocate more fixation time to critical information and less time to peripheral or potentially interfering information. Correlational analyses, recall performance, metacognitive monitoring, and controlling indicate significant interrelations between all of these measures, with varying patterns of correlations within age groups. Results are discussed in regard to the intricate relationship between monitoring and recall and their relation to performance.

University and school students' motivation for effortful thinking: Factor structure, reliability, and validity of the German Need for Cognition Scale

Need for cognition (NFC) reflects a relatively stable trait regarding the degree to which one enjoys and engages in cognitive endeavors. We examined whether the previously demonstrated one-dimensional structure of the German NFC Scale could be replicated in three samples of undergraduates and secondary school students. Moreover, we investigated the test-retest reliability of the German NFC Scale, which has not yet been tested. Further, we investigated whether the scale would be valid in a sample of secondary school students. Multigroup confirmatory factor analyses established the one-dimensional factor structure of the long form as well as the short form of the German NFC Scale for undergraduates (N = 559), students of academic track secondary schools (German Gymnasium; N = 555), and students of vocational track secondary schools (German Realschule; N = 486). The scale proved to have a high test-retest reliability in a university student sample (N = 43). For secondary school students, we again found a high test-retest reliability (N = 157), and also found the scale to be valid (N = 181).

‘Idolatry’ and Religious Diversity: Thinking about the Other in Early Modern Europe

Idolatry is a key concept in the history of Western thinking about religion, as an all-encompassing category in which all religions more or less alien to the Christian tradition could be subsumed. From Late Antiquity to the Modern period, we can follow how the notion was put to work within Christian discourse to think about the religious “other. ” In fact, the word is almost ubiquitous in pre-modern debates on religion and the origins of religion. Theories on the nature and causes of “idolatry” framed much of the issue of “Religion” vs. the “religions,” and largely provided the conceptual space, in early modern Europe, in which religious anthropology would emerge. The present paper will investigate some aspects of the early modern discourse on idolatry, and its place in early modern discussions on the “diversity” of religions.
