(2017): Understanding the influence of power and empathic perspective-taking on collaborative natural resource management. In: Journal of environmental management 199, S. 201-210. DOI: 10.1016/j.jenvman.2017.05.030
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28544926 Abstract: Public engagement in collaborative natural resource management necessitates shared understanding and collaboration. Empathic perspective-taking is a critical facilitator of shared understanding and positive social interactions, such as collaboration. Yet there is currently little understanding about how to reliably generate empathic perspective-taking and collaboration, particularly in situations involving the unequal distribution of environmental resources or power. Here we examine how experiencing the loss or gain of social power influenced empathic perspective-taking and behavior within a computer-mediated scenario. Participants (n = 180) were randomly assigned to each condition: high resources, low resources, lose resources, gain resources. Contrary to our expectations, participants in the perspective-taking condition, specifically those who lost resources, also lost perspective taking and exhibited egoistic behavior. This finding suggests that resource control within the collaborative process is a key contextual variable that influences perspective-taking and collaborative behavior. Moreover, the observed relationship between perspective-taking and egoistic behavior within a collaborative resource sharing exercise suggests that when resource control or access is unequal, interventions to promote perspective-taking deserve careful consideration. Highlights •The collaborative scenario shifted players' perspective taking and collaborative behavior. •Loss of resources, control, or power reduces perspective taking. •Loss of resources, control, or power increases selfish behavior. •Perspective-taking was a significant predictor of collaborative behavior. •A modified framework for collaborative governance is proposed.

(2017): Social exclusion of older persons. A scoping review and conceptual framework. In: European journal of ageing 14 (1), S. 81-98. DOI: 10.1007/s10433-016-0398-8
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28804395 Abstract: As a concept, social exclusion has considerable potential to explain and respond to disadvantage in later life. However, in the context of ageing populations, the construct remains ambiguous. A disjointed evidence-base, spread across disparate disciplines, compounds the challenge of developing a coherent understanding of exclusion in older age. This article addresses this research deficit by presenting the findings of a two-stage scoping review encompassing seven separate reviews of the international literature pertaining to old-age social exclusion. Stage one involved a review of conceptual frameworks on old-age exclusion, identifying conceptual understandings and key domains of later-life exclusion. Stage two involved scoping reviews on each domain (six in all). Stage one identified six conceptual frameworks on old-age exclusion and six common domains across these frameworks: neighbourhood and community; services, amenities and mobility; social relations; material and financial resources; socio-cultural aspects; and civic participation. International literature concentrated on the first four domains, but indicated a general lack of research knowledge and of theoretical development. Drawing on all seven scoping reviews and a knowledge synthesis, the article presents a new definition and conceptual framework relating to old-age exclusion.

(2017): Perceiving and Confronting Sexism. The Causal Role of Gender Identity Salience. In: Psychology of Women Quarterly 41 (1), S. 65-76. DOI: 10.1177/0361684316670628
DOI: https://doi.org/10.1177/0361684316670628 Abstract: Although many researchers have explored the relations among gender identification, discriminatory attributions, and intentions to challenge discrimination, few have examined the causal impact of gender identity salience on women's actual responses to a sexist encounter. In the current study, we addressed this question by experimentally manipulating the salience of gender identity and assessing its impact on women's decision to confront a sexist comment in a simulated online interaction. Female participants (N = 114) were randomly assigned to complete a short measure of either personal or collective self-esteem, which was designed to increase the salience of personal versus gender identity. They were then given the opportunity to confront a male interaction partner who expressed sexist views. Compared to those who were primed to focus on their personal identity, participants who were primed to focus on their gender identity perceived the interaction partner's remarks as more sexist and were more likely to engage in confrontation. By highlighting the powerful role of subtle contextual cues in shaping women's perceptions of, and responses to, sexism, our findings have important implications for the understanding of gender identity salience as an antecedent of prejudice confrontation.

(2017): The Malleability of Stereotype Effects on Spontaneous Trait Inferences. In: Social Psychology 48 (1), S. 3-18. DOI: 10.1027/1864-9335/a000288
DOI: https://doi.org/10.1027/1864-9335/a000288 Abstract: Past research has demonstrated that perceivers are more likely to draw spontaneous trait inferences (STIs) from stereotype-consistent behaviors than from stereotype-inconsistent behaviors. Four studies were conducted to examine the moderating role of power in stereotype effects on STIs. Priming power using the scrambled sentence task, Study 1 found that high-power participants drew STIs from elderly stereotype-consistent but not from elderly stereotype-inconsistent sentences, while low-power participants did not draw STIs from elderly stereotype-consistent or stereotype-inconsistent behaviors. Study 2 replicated the findings of Study 1 by exploring the moderating role of power in gender stereotype effects on STIs. Measuring participants’ dispositional power via the Personal Sense of Power, Study 3 found that dispositional power also moderated the effects of gender stereotype on STIs. Study 4 found that compared with the baseline condition (no-power manipulation), the low-power condition inhibited STIs from stereotype-consistent behaviors, but the high-power condition did not facilitate STI formation from stereotype-consistent behaviors. The current study is the first to show that power influences the reliance on stereotypes when spontaneously inferring traits from behaviors.

(2017): Evaluating the Sensitivity to Virtual Characters Facial Asymmetry in Emotion Synthesis. In: Applied Artificial Intelligence 31 (2), S. 103-118. DOI: 10.1080/08839514.2017.1299983
Abstract: The use of expressive Virtual Characters is an effective complementary means of communication for social networks offering multi-user 3D-chatting environment. In such contexts, the facial expression channel offers a rich medium to translate the ongoing emotions conveyed by the text-based exchanges. However, until recently, only purely symmetric facial expressions have been considered for that purpose. In this article we examine human sensitivity to facial asymmetry in the expression of both basic and complex emotions. The rationale for introducing asymmetry in the display of facial expressions stems from two well-established observations in cognitive neuroscience: first that the expression of basic emotions generally displays a small asymmetry, second that more complex emotions such as ambivalent feeling may reflect in the partial display of different, potentially opposite, emotions on each side of the face. A frequent occurrence of this second case results from the conflict between the truly felt emotion and the one that should be displayed due to social conventions. Our main hypothesis is that a much larger expressive and emotional space can only be automatically synthesized by means of facial asymmetry when modeling emotions with a general Valence-Arousal-Dominance dimensional approach. Besides, we want also to explore the general human sensitivity to the introduction of a small degree of asymmetry into the expression of basic emotions. We conducted an experiment by presenting 64 pairs of static facial expressions, one symmetric and one asymmetric, illustrating eight emotions (three basic and five complex ones) alternatively for a male and a female character. Each emotion was presented four times by swapping the symmetric and asymmetric positions and by mirroring the asymmetrical expression. Participants were asked to grade, on a continuous scale, the correctness of each facial expression with respect to a short definition. Results confirm the potential of introducing facial asymmetry for a subset of the complex emotions. Guidelines are proposed for designers of embodied conversational agent and emotionally reflective avatars.

(2017): Designing talk in social networks. What Facebook teaches about conversation. In: LANGUAGE LEARNING 21 (2), S. 121-137
Abstract: The easy accessibility, ubiquity, and plurilingualism of popular SNSs such as Facebook have inspired many scholars and practitioners of second language teaching and learning to integrate networked forms of communication into educational contexts such as language classrooms and study abroad programs (e.g., Blattner & Fiori, 2011; Lamy & Zourou, 2013; Mills, 2011; Reinhardt & Ryu, 2013; Reinhardt & Zander, 2011). At the same time, the complex and dynamic patterns of interaction that emerge in these spaces quickly push back upon standard ways of describing conversational genres and communicative competence (Kern, 2014; Lotherington & Ronda, 2014). Drawing from an ecological interactional analysis (Goffman, 1964, 1981a, 1981b, 1986; Kramsch & Whiteside, 2008) of the Facebook communications of three German-speaking academics whose social and professional lives are largely led in English, the authors consider the kinds of symbolic maneuvers required to participate in the translingual conversational flows of SNS-mediated communication. Based on this analysis, this article argues that texts generated through SNS-mediated communication can provide classroom opportunities for critical, stylistically sensitive reflection on the nature of talk in line with multiliteracies approaches.

(2017): Power Moves Beyond Complementarity. A Staring Look Elicits Avoidance in Low Power Perceivers and Approach in High Power Perceivers. In: Personality & social psychology bulletin 43 (8), S. 1188-1201. DOI: 10.1177/0146167217708576
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28903712 Abstract: Sustained, direct eye-gaze—staring—is a powerful cue that elicits strong responses in many primate and nonprimate species. The present research examined whether fleeting experiences of high and low power alter individuals’ spontaneous responses to the staring gaze of an onlooker. We report two experimental studies showing that sustained, direct gaze elicits spontaneous avoidance tendencies in low power perceivers and spontaneous approach tendencies in high power perceivers. These effects emerged during interactions with different targets and when power was manipulated between-individuals (Study 1) and within-individuals (Study 2), thus attesting to a high degree of flexibility in perceivers’ reactions to gaze cues. Together, the present findings indicate that power can break the cycle of complementarity in individuals’ spontaneous responding: Low power perceivers complement and move away from, and high power perceivers reciprocate and move toward, staring onlook ers.

(2017): Robots As Intentional Agents: Using Neuroscientific Methods to Make Robots Appear More Social. In: Frontiers in psychology 8. DOI: 10.3389/fpsyg.2017.01663
DOI: http://www.ncbi.nlm.nih.gov/pubmed/29046651 Abstract: Robots are increasingly envisaged as our future cohabitants. However, while considerable progress has been made in recent years in terms of their technological realization, the ability of robots to interact with humans in an intuitive and social way is still quite limited. An important challenge for social robotics is to determine how to design robots that can perceive the user's needs, feelings, and intentions, and adapt to users over a broad range of cognitive abilities. It is conceivable that if robots were able to adequately demonstrate these skills, humans would eventually accept them as social companions. We argue that the best way to achieve this is using a systematic experimental approach based on behavioral and physiological neuroscience methods such as motion/eye-tracking, electroencephalography, or functional near-infrared spectroscopy embedded in interactive human-robot paradigms. This approach requires understanding how humans interact with each other, how they perform tasks together and how they develop feelings of social connection over time, and using these insights to formulate design principles that make social robots attuned to the workings of the human brain. In this review, we put forward the argument that the likelihood of artificial agents being perceived as social companions can be increased by designing them in a way that they are perceived as intentional agents that activate areas in the human brain involved in social-cognitive processing. We first review literature related to social-cognitive processes and mechanisms involved in human-human interactions, and highlight the importance of perceiving others as intentional agents to activate these social brain areas. We then discuss how attribution of intentionality can positively affect human-robot interaction by (a) fostering feelings of social connection, empathy and prosociality, and by (b) enhancing performance on joint human-robot tasks. Lastly, we describe circumstances under which attribution of intentionality to robot agents might be disadvantageous, and discuss challenges associated with designing social robots that are inspired by neuroscientific principles.

(2017): Impoliteness in EFL. Foreign Language Learners’ Complaining Behaviors Across Social Distance and Status Levels. In: SAGE Open 7 (3). DOI: 10.1177/2158244017732816
Abstract: A growing body of literature has investigated impoliteness in many domains. Nevertheless, little research has examined impoliteness done by foreign language learners. Impoliteness used in interlanguage complaints by English as a foreign language learners was observed. The effects of interlocutors' different status levels and social distance on the use of impoliteness were analyzed. Empirical data were elicited by means of oral discourse completion tasks from 50 Indonesian English as a foreign language learners in Central Java, Indonesia. The overall direction of the findings showed trends that status levels and social distance between interlocutors prompted different frequencies and strategies of impoliteness. The frequent use of impolite complaints was instigated by a number of factors such as the learners' understanding about the speech act in question, their perceptions on the social distance and status levels of interlocutors, and the nature of the research instrument.

(2017): Enabling robotic social intelligence by engineering human social-cognitive mechanisms. In: COGNITIVE SYSTEMS RESEARCH 43, S. 190-207. DOI: 10.1016/j.cogsys.2016.09.005
DOI: https://doi.org/10.1016/j.cogsys.2016.09.005 Abstract: For effective human-robot interaction, we argue that robots must gain social-cognitive mechanisms that allow them to function naturally and intuitively during social interactions with humans. However, a lack of consensus on social cognitive processes poses a challenge for how to design such mechanisms for artificial cognitive systems. We discuss a recent integrative perspective of social cognition to provide a systematic theoretical underpinning for computational instantiations of these mechanisms. We highlight several commitments of our approach that we refer to as Engineering Human Social Cognition. We then provide a series of recommendations to facilitate the development of the perceptual, motor, and cognitive architecture for this proposed artificial cognitive system in future work. For each recommendation, we highlight their relation to the discussed social-cognitive mechanisms, provide the rationale for these recommendations and potential benefits, and detail examples of associated computational formalisms that could be leveraged to instantiate our recommendations. Overall, the goal of this paper is to outline an interdisciplinary and multi-theoretic approach to facilitate the design of robots that will one day function, and be perceived, as socially interactive and effective teammates.

(2017): Needs and values. An exploration. In: The Humanistic Psychologist 45 (3), S. 295-311. DOI: 10.1037/hum0000054
Abstract: Maslow contended that different needs are associated with different values. Therefore, the objective of the present study was to identify the values that are correlated with each of the needs in Maslow’s hierarchy using an Indian sample of young adults. The Deficiency-Need Preoccupation Checklist, a measure of preoccupation with each of the deficiency-needs (d-needs), was developed for the purpose of the present study. Participants (N = 200) completed 4 assessments: the Deficiency-Need Preoccupation Checklist, Satisfaction with Life Scale, Short Index of Self-Actualization, and Portrait of Values Questionnaire–Revised. We found support for a 4-factor structure of d-need preoccupation, in accordance with Maslow’s hierarchy. Furthermore, d-need preoccupation correlated negatively with self-actualization; the magnitude of the coefficient between d-need preoccupation and self-actualization strengthened as the theoretical proximity between the need and self-actualization increased. In addition, the values that correlated positively with d-needs and negatively with self-actualization belonged to the value clusters 'self-enhancement' and 'conservation'; conversely, the values that correlated negatively with d-needs and positively with self-actualization belonged to the value clusters 'self-transcendence' and 'openness to change.'

(2017): Whether power holders construe their power as responsibility or opportunity influences their tendency to take advice from others. In: Journal of Organizational Behavior 38 (7), S. 923-949. DOI: 10.1002/job.2171
Abstract: Investigated different responses that power holders demonstrate in their tendency to take advice depending on the construal of power. A field study was conducted with 49 supervisors (mean age 42 years) and 54 of their subordinates (mean age 36 years) representing a wide range of organizations and industries in Australia, Malaysia, and Israel. A second field study was conducted with 217 individuals (mean age 42 years) in high-power positions in Chile and the Netherlands. A final experiment was performed with 75 Western Europeans (mean age 21 years), in which participants were assigned to a more or less powerful role. Across all three investigations, higher tendencies to take advice were observed among individuals who construed their power as a responsibility as opposed to an opportunity. Furthermore, the impact of construal of power on advice-taking was moderated by a heightened perceived value of advice, but not by decreased confidence in personal judgments or personal sense of power. As a result, openness to advice-taking when power was construed as a responsibility occurred regardless of whether advice was offered by subordinates, expert advisors, or a less powerful person. Future research imperatives include an examination of possible gender differences in the observed effects.

(2017): Towards a social functional account of laughter. Acoustic features convey reward, affiliation, and dominance. In: PLoS one 12 (8). DOI: 10.1371/journal.pone.0183811
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28850589 Abstract: Recent work has identified the physical features of smiles that accomplish three tasks fundamental to human social living: rewarding behavior, establishing and managing affiliative bonds, and negotiating social status. The current work extends the social functional account to laughter. Participants (N = 762) rated the degree to which reward, affiliation, or dominance (between-subjects) was conveyed by 400 laughter samples acquired from a commercial sound effects website. Inclusion of a fourth rating dimension, spontaneity, allowed us to situate the current approach in the context of existing laughter research, which emphasizes the distinction between spontaneous and volitional laughter. We used 11 acoustic properties extracted from the laugh samples to predict participants' ratings. Actor sex moderated, and sometimes even reversed, the relation between acoustics and participants' judgments. Spontaneous laughter appears to serve the reward function in the current framework, as similar acoustic properties guided perceiver judgments of spontaneity and reward: reduced voicing and increased pitch, increased duration for female actors, and increased pitch slope, center of gravity, first formant, and noisiness for male actors. Affiliation ratings diverged from reward in their sex-dependent relationship to intensity and, for females, reduced pitch range and raised second formant. Dominance displayed the most distinct pattern of acoustic predictors, including increased pitch range, reduced second formant in females, and decreased pitch variability in males. We relate the current findings to existing findings on laughter and human and non-human vocalizations, concluding laughter can signal much more that felt or faked amusement.

(2017): Habit in Personality and Social Psychology. In: Personality and social psychology review : an official journal of the Society for Personality and Social Psychology, Inc 21 (4), S. 389-403. DOI: 10.1177/1088868317720362
DOI: http://www.ncbi.nlm.nih.gov/pubmed/28737111 Abstract: Habits are largely absent from modern social and personality psychology. This is due to outdated perspectives that placed habits in conflict with goals. In modern theorizing, habits are represented in memory as implicit context-response associations, and they guide responding in conjunction with goals. Habits thus have important implications for our field. Emerging research shows that habits are an important mechanism by which people self-regulate and achieve long-term goals. Also, habits change through specific interventions, such as changes in context cues. I speculate that understanding of habits also holds promise for reducing intergroup discrimination and for understanding lay theories of the causes for action. In short, by recognizing habit, the field gains understanding of a central mechanism by which actions persist in daily life. zitiert von 6

(2017): Detecting deceptive engagement in social media by temporal pattern analysis of user behaviors. A survey. In: Wiley Interdisciplinary Reviews: Data Mining and Knowledge Discovery 7 (5). DOI: 10.1002/widm.1210
Abstract: Deceptive engagement in social media, such as spamming, commenting, or rating with automatic scripts, spreading fabricated facts, seriously affects users' trust on online services. Given the large volumes of information generated by users, effectively spotting users involved such deceptive engagement has become a challenging problem. Recent research has shown that techniques for analyzing temporal behavioral patterns are critical to address such problem. In this study, we survey recent advances in these techniques. We first summarize three approaches to model temporal information. Then, by using representative application examples, we discuss recent approaches with respect to their applications to real-world large-scale social media. With a focus on the temporal perspective, we then discuss advantages and challenges of each approach. (C) 2017 John Wiley & Sons, Ltd

(2017): Ethical leadership and pro-social rule breaking. A dual process model. In: Acta Psychologica Sinica 49 (1). DOI: 10.3724/SP.J.1041.2017.00106
DOI: https://doi.org/10.3724/SP.J.1041.2017.00106 Abstract: Pro-social rule breaking (PSRB), as one form of constructive deviance, is receiving increasing attention from researchers, yet surprisingly our knowledge of the antecedents of PSRB is fairly limited. Although the effects of personal traits on PSRB are well discussed in the literature, we know little about how contextual factors in the work environment, such as leadership style, shape PSRB. The current study aims to address this research gap by examining the relationship between ethical leadership and PSRB. Specifically, drawing from the social information processing theory, we propose a dual process model that ethical leadership enhances employees' PSRB via psychological safety and job autonomy. We further investigate the moderating effect of employees' risk taking propensity in the model. The participants were recruited from four organizations in three cities of China (i.e., Beijing, Shanghai, and Dalian). The data was collected at two time points to avoid the common met hod bias . At Time 1, ethical leadership, psychological safety, job autonomy, and risk taking propensity were measured. At Time 2, that is, one month later, participants' PSRB behavior was assessed. The final sample size was 241. We used SPSS 22.0 and Mplus 6.12 to analyse the data. First, we assessed the discriminant validity of the key variables through a series of confirmatory factor analyses (CPAs) and examined the common method variance. Afterwards, we used the Structural Equation Modeling (SEM) and bias-corrected bootstrap to test our hypotheses. The results showed a significantly positive relationship between ethical leadership and PSRB, and the relationship was mediated by psychological safety and job autonomy. Furthermore, individual risk taking propensity moderated the relationship between job autonomy and PSRB, such that the positive relationship was stronger for those employees with higher, rather than lower, levels of risk taking propensity. Our study contributes to the PSRB lit erature in several ways. Frist, we investigate the effects of ethical leadership on employees' PSRB, which broadens our understanding of how contextual factors influences PSRB. Second, we reveal the theoretical black-box of why ethical leadership facilitates PSRB by identifying psychological safety and job autonomy as two underlying mechanisms. Finally, we extend the ethical leadership and PSRB research by demonstrating risk taking propensity as a crucial contingency that moderates the effects of ethical leadership and job autonomy on PSRB.

Abstract: The Hard Problem of consciousness has been dismissed as an illusion. By showing that computers are capable of experiencing, we show that they are at least rudimentarily conscious with potential to eventually reach superconsciousness. The main contribution of the paper is a test for confirming certain subjective experiences in a tested agent. We follow with analysis of benefits and problems with conscious machines and implications of such capability on future of computing, machine rights and artificial intelligence safety.

(2017) : A study on the social acceptance of a robot in a multi-human interaction using an F-formation based motion model: 2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS): Vancouver, British Columbia, Canada: IEEE, S. 2766-2771
DOI: https://doi.org/10.1109/IROS.2017.8206105 Abstract: As robots participate in human’s daily activities more and more frequently, mobility performance has become one of the main factors determining how robots will share an environment with humans harmoniously in the near future. Among several different kinds of mobile platforms, using omnidirectional configurations is gradually becoming a trend in the robotics community; however, few researchers have addressed the impact of omnidirectional mobility from the perspective of human-robot interaction (HRI). In this paper, we have proposed a socializing model for the robot while participating in an interaction with a group of human peers to achieve its socially optimal position. From a theoretic perspective, we first identify the most prominent features required for social acceptance of robots interacting with multiple humans, backing our arguments with relevant sociological theory. To validate our results, we have conducted experiments where human participants were invited to interact with a robot, which can be constrained to perform either holonomic or nonholonomic motions only. Then, through an observer survey, we testify the appropriateness of utilizing omnidirectional mobility and verify the promotion of social acceptance using the aforementioned features, which is a goal that both the HRI and robotics communities aim to achieve.

(2017): Recovering a "Disfigured" Face. In: Techné: Research in Philosophy and Technology 21 (1), S. 1-23. DOI: 10.5840/techne2016121659
Abstract: Prosthetic devices that replace an absent body part are generally considered to be either cosmetic or functional. Functional prostheses aim to restore (some degree of) lost physical functioning. Cosmetic prostheses attempt to restore a “normal” appearance to bodies that lack (one or more) limbs by emulating the absent body part’s looks. In this article, we investigate how cosmetic prostheses establish a normal appearance by drawing on the stories of the users of a specific type of artificial limb: the facial prosthesis. Given that prostheses are first and foremost devices worn upon the body, such an analysis requires an understanding of the ways in which bodies and technologies interact. We thus interpret users’ stories by critically engaging with the work of disability researcher and Actor-Network theorist Myriam Winance, as well as with the postphenomenological scholarship of Don Ihde and Peter-Paul Verbeek. Using this framework, we explore users’ attempts to achieve a proper fit between their faces and their prostheses, the technological transparency such a fit enables, and the ways in which transparency mediates users’ everyday exchanges with others. We conclude that a normal appearance, when it is achieved by means of prosthetics, enables the device’s user to navigate a precarious social environment as they encounter and interact with others in public.

(2017): The Neural Basis of Changing Social Norms through Persuasion. In: Scientific reports 7 (1). DOI: 10.1038/s41598-017-16572-2
DOI: http://www.ncbi.nlm.nih.gov/pubmed/29176682 Abstract: Social norms regulate behavior, and changes in norms have a great impact on society. In most modern societies, norms change through interpersonal communication and persuasive messages found in media. Here, we examined the neural basis of persuasion-induced changes in attitude toward and away from norms using fMRI. We measured brain activity while human participants were exposed to persuasive messages directed toward specific norms. Persuasion directed toward social norms specifically activated a set of brain regions including temporal poles, temporo-parietal junction, and medial prefrontal cortex. Beyond these regions, when successful, persuasion away from an accepted norm specifically recruited the left middle temporal and supramarginal gyri. Furthermore, in combination with data from a separate attitude-rating task, we found that left supramarginal gyrus activity represented participant attitude toward norms and tracked the persuasion-induced attitude changes that were away from agreement.

(2017): Translating the FAITH Frame. A Study of Two Translated Egyptian Novels. In: Complutense Journal of English Studies 25, S. 125-142. DOI: 10.5209/CJES.57598
DOI: https://doi.org/10.5209/CJES.57598 Abstract: This study, which is part of a larger study on the use of frame semantics in the translation of cultural elements from Arabic into English, isolates the instances where the characters from two modern Egyptian novels use language to identify themselves as members of a particular religious group, which corresponds to the frame generic→faith, and examines the manner in which these instances are translated into English. In this sense, faith is a generic frame because it dictates a particular set of behaviors, both linguistic and ideological, that is enforced by the faith community and practiced by the individuals within it. This faith community is a subset of the language community that uses a set of expressions considered typical of this community to the point where its members are recognizable through the use of these expressions. The translation issue at hand is that the TL may not offer the same possibilities to evoke a similar frame reflecting religious identity.

(2017): Political inertia and social acceleration. In: Philosophy & Social Criticism 43 (7), S. 707-723. DOI: 10.1177/0191453716669195
Abstract: There is a complicated relation between social and political inertia - the failure of institutions to respond adequately to social, technological and environmental change - and social acceleration - the tendency of social change to go faster and faster. Social stasis and acceleration are not simply opposed but also causally related. This article contrasts two theories of political and social inertia. Francis Fukuyama argues that political inertia is a result of a cognitive and institutional rigidity which is ultimately grounded in human nature, and that therefore inertia is a feature inherent in political systems. Hartmut Rosa, by contrast, sees inertia as a specifically modern phenomenon, which is the result of the inability of political institutions to cope with the accelerating rate of change in other social systems. It will be argued that a broad approach combining historical, institutional and normative perspectives is needed to explain political inertia.
