  • Brock, Andrew; Donahue, Jeff; Simonyan, Karen (2018): Large Scale GAN Training for High Fidelity Natural Image Synthesis. Online verfügbar unter http://arxiv.org/pdf/1809.11096v2

     

    Abstract: Despite recent progress in generative image modeling, successfully generating high-resolution, diverse samples from complex datasets such as ImageNet remains an elusive goal. To this end, we train Generative Adversarial Networks at the largest scale yet attempted, and study the instabilities specific to such scale. We find that applying orthogonal regularization to the generator renders it amenable to a simple "truncation trick," allowing fine control over the trade-off between sample fidelity and variety by reducing the variance of the Generator's input. Our modifications lead to models which set the new state of the art in class-conditional image synthesis. When trained on ImageNet at 128x128 resolution, our models (BigGANs) achieve an Inception Score (IS) of 166.5 and Frechet Inception Distance (FID) of 7.4, improving over the previous best IS of 52.52 and FID of 18.6.

  • Broussard, Meredith (2018): Artificial unintelligence. How computers misunderstand the world. Cambridge, Massachusetts: The MIT Press

    Abstract: A guide to understanding the inner workings and outer limits of technology and why we should never assume that computers always get it right. In Artificial Unintelligence, Meredith Broussard argues that our collective enthusiasm for applying computer technology to every aspect of life has resulted in a tremendous amount of poorly designed systems. We are so eager to do everything digitally—hiring, driving, paying bills, even choosing romantic partners—that we have stopped demanding that our technology actually work. Broussard, a software developer and journalist, reminds us that there are fundamental limits to what we can (and should) do with technology. With this book, she offers a guide to understanding the inner workings and outer limits of technology—and issues a warning that we should never assume that computers always get things right. Making a case against technochauvinism—the belief that technology is always the solution—Broussard argues that it's just not true that social problems would inevitably retreat before a digitally enabled Utopia. To prove her point, she undertakes a series of adventures in computer programming. She goes for an alarming ride in a driverless car, concluding “the cyborg future is not coming any time soon”; uses artificial intelligence to investigate why students can't pass standardized tests; deploys machine learning to predict which passengers survived the Titanic disaster; and attempts to repair the U.S. campaign finance system by building AI software. If we understand the limits of what we can do with technology, Broussard tells us, we can make better choices about what we should do with it to make the world better for everyone.

  • Brown, Matthew D. (2018): Applied global health diplomacy: profile of health diplomats accredited to the UNITED STATES and foreign governments. In: GLOBALIZATION AND HEALTH 14

    Abstract: Background: Global health diplomacy (GHD) is a burgeoning field bridging the priorities of global health and foreign affairs. Given the increasing need to mobilize disparate global health stakeholders coupled with the need to design complex public health partnerships to tackle issues of international concern, effective and timely cooperation among state actors is critical. Health Attaches represent this coordination focal point and are key diplomatic professionals at the forefront of GHD. Despite their unique mandate, little is published about this profession and the perspectives of those who work in the field. Methods: Through purposive sampling, we performed in-depth qualitative interviews with seven Health Attaches: three foreign Health Attaches accredited to the United States and four U.S. Health Attaches accredited to foreign governments. Our interviews explored four key topics: the role and mission of Health Attaches, skills needed to perform GHD, examples of successes and challenges in accomplishing their respective missions, and suggestions for the future development of the diplomatic profession. Results: We identified several lessons to apply to the growing field of GHD. First, GHD actors need to receive appropriate training to successfully negotiate the intersection of global health and foreign affairs. Participants suggested several areas of training that would benefit GHD actors: diplomacy and negotiation, applied science, and cross-cultural competency. Second, participants articulated the need for a career path for GHD practitioners, increased opportunities for on-the-job training and mentored experiences, and GHD competencies with defined levels of mastery that can be used in occupational evaluation and career development. Conclusions: Our findings indicate that skills in diplomacy and negotiation, applied science, and cross cultural competency are essential for the statecraft of Health Attaches. Additionally, establishing a clear career pathway for Health Attaches is critical for future maturation of the profession and for fostering effective global health action that aligns public health and foreign diplomacy outcomes. Achieving these goals would ensure that this special cadre of diplomats could effectively practice GHD and would also better position Health Attaches to take the lead in advancing shared global health goals among nation states in a new era of twenty-first century diplomacy.

    Abstract: Was haben die Wassertankversuche der frühen Raumfahrtforschung im 20. Jahrhundert, die Gestaltungspraktiken von Grabsteinen auf Friedhöfen der Gegenwart und die Einritzungen von Stifternamen an den Kirchenwänden der Frühen Neuzeit miteinander zu tun? Auf je unterschiedliche Art und Weise stellen diese Praktiken Formen der Verräumlichung von Identität dar. Raum und Identität sind nicht als separierte Entitäten zu denken, sondern stehen – so die Leitthese von „Das verräumlichte Selbst“ – in einem sich wechselseitig bedingenden Verhältnis von Kontingenz und Stabilität. Mit der Frage nach den Praktiken der Verräumlichung des Selbst will der Band das vielschichtige Gefüge identitätsproduzierender Räumlichkeiten und raumproduzierender Identitäten beleuchten. Räume werden nicht nur von Menschen geschaffen oder ‚gebaut‘, in ihnen konstituiert sich gleichzeitig auch Identität. Mit Räumen werden Identitätspositionen bestätigt, gebrochen oder verfremdet. Räume haben eine identitätsproduzierende Dimension, umgekehrt bringen Identitäten Räume auch hervor. Bestehende Selbstverhältnisse sind somit auch Bedingung für die Hervorbringung spezifischer Raumkonstellationen. Die interdisziplinär angelegte Publikation versammelt Beiträge aus der Soziologie, der (Wissens-)Geschichte, der Philosophie, den Sprachwissenschaften sowie der Museumspraxis. In historischen und regionalen Fallstudien sowie theoretischen und epochenübergreifenden Beiträgen wird das epistemologische Potenzial des Spatial Turn in den Kulturwissenschaften für Fragen nach der Identitätskonstruktion sowie der Rolle von Selbstverhältnissen für die Raumproduktion erschlossen. Der Band versteht sich dabei als ein doppeltes Unterfangen: In theoretisch-systematischer Herleitung werden zum einen Analysen von Identitäts- und Raumkonzepten in ihren wechselseitigen Bedingtheiten vorangetrieben. Zum anderen sind Raum und Identität selbst Gegenstand für Analysen regionaler und zeitlich gebundener Praktiken.

    Abstract: Flying Laptop (FLP) is an active satellite mission by the University of Stuttgart. For payload control and data management the satellite has a dedicated payload on-board computer (PLOC) which is based on an SRAM FPGA. The FPGA can be configured at any time with any configuration without endangering the satellite itself. This enables the Flying Laptop to be offered as a testbed for in-orbit testing of radiation mitigation designs in computing application with a low barrier for entry. This also extends to opportunities to execute educational experiments in orbit. Furthermore one of the payload subsystems consist of a software defined radio (SDR) transmitter in the 2.4 GHz amateur radio band. While currently being used for payload data downlink, it is also available as an operational testbed for experiments in space communication.

    Abstract: We describe two types of experimental evolution studies of 'mismatch' that are relevant to economics. 'Evolutionary mismatch' is the concept that an organism can be importantly 'out of sync' with its environment. In such cases, an organism may choose an option that is inferior to a feasible alternative. Mainstream and behavioral economics do not address the notion of evolutionary mismatch. We argue for an empirical program on mismatch utilizing the methodology of experimental evolution. (PsycINFO Database Record (c) 2018 APA, all rights reserved)

    Abstract: Die innovative Studie wendet Verfahren der linguistisch-semantischen Frame-Analyse auf die Rekonstruktion komplexer fachlich-institutioneller Begriffe in der Domäne „Recht“ an und diskutiert intensiv die Möglichkeiten und Grenzen dieser Methode. Es werden Begriffe und Begriffsnetze aus den Rechtsgebieten Strafrecht und Bürgerliches Recht analysiert und frame-semantisch rekonstruiert; dabei werden z.T. auch konkurrierende Begriffsdeutungen und diachrone Begriffsentwicklungen mit erfasst. Die Studie leistet Pionierarbeit, da bisher keine anderen Publikationen vorliegen, die auch praktisch-empirisch Bedeutungs- und Begriffswissens-Frames so umfassend und intensiv beschreiben und frame-semantisch darstellen wie hier. Die Aspekte und Probleme einer solchen korpusgestützt und empirisch detailliert arbeitenden Frame-Analyse werden ausführlich dokumentiert und diskutiert. Sie zeigen die Leistungsfähigkeit dieser Methode (aber auch, wo ihre Grenzen liegen). Insofern kann diese Arbeit Vorbild für ähnlich orientierte Studien auch zu anderen Sprachgebrauchs- und Wissens-Domänen sein, und das geplante Buch deshalb auf das Interesse anderer in diesem Feld tätiger Forscherinnen und Forscher stoßen.

    DOI: http://www.ncbi.nlm.nih.gov/pubmed/29323517 

    Abstract: Individual differences in behavior are understood generally as arising from an interaction between genes and environment, omitting a crucial component. The literature on animal and human learning suggests the need to posit principles of learning to explain our differences. One of the challenges for the advancement of the field has been to establish how general principles of learning can explain the almost infinite variation in behavior. We present a case that: (a) individual differences in behavior emerge, in part, from principles of learning; (b) associations provide a descriptive mechanism for understanding the contribution of experience to behavior; and (c) learning theories explain dissociable aspects of behavior. We use 4 examples from the field of learning to illustrate the importance of involving psychology, and associative theory in particular, in the analysis of individual differences, these are (a) fear learning; (b) behavior directed to cues for outcomes (i.e., sign- and goal- tracking); (c) stimulus learning related to attention; and (d) human causal learning.

    Abstract: The academic success of individual students differs widely and it depends on various factors, ranging from financial to social and to health aspects. In this article, we propose a concept for a novel productivity tracking system that provides the basis for a self-assessment of academic behaviour and that can be used by students to support their academic success. The development of such a system requires interdisciplinary efforts, most of them located in the field of collaborative interactive learning (CIL) that is grounded on a socio-technical system perspective. The system is interactive since it is based on bidirectional communication, collaborative in the sense that it uses students, other students, and external sources such as the Internet for generation of knowledge, and learning in the sense that it continuously and autonomously acquires knowledge. It is further self-organised as it decides about interaction partners and self-adaptive in terms of modifying its behaviour according to changing conditions.

  • Cameron, C. D.; Scheffer, J. A.; Spring, V. L. (2018) : Implicit moral cognition. In: Gray, Kurt James; Graham, Jesse (Hg.): Atlas of moral psychology: What do we evaluate when we evaluate moral character? - Helzer, Erik G.; Critcher, Clayton R.: New York, NY: The Guilford Press, S. 516-524

    Abstract: What is the best method for understanding moral judgment? We use implicit measurement and mathematical modeling to capture implicit moral evaluations, because this method can address debates over the role of intuition and reason in moral judgment and over domain-general versus domain-specific views of moral psychology. A man kicks a puppy as hard as he can. A son slaps his mother across the face. A soldier betrays his unit. A terrorist defiles a temple. These actions all seem like moral transgressions. And before you deliberate about why they are wrong—that is, what principles do they violate—you probably have an immediate gut reaction: 'That is wrong!' If you don’t have that reaction, that is important for us and everyone else to know, because it might mean you have fewer inhibitions about engaging in such behaviors. And you might know what the 'appropriate' reaction is supposed to look like, so it’s important to find a way to reliably assess your gut reactions b efore yo u can edit your responses. In this chapter, we discuss a new approach to measuring moral intuitions that draws upon advances in implicit social cognition and mathematical modeling.

    Abstract: Previous studies on social skills training on ASD were done almost exclusively in the West with children as the main subjects. Demonstrations of the applicability of social interventions in different cultures and age groups are warranted. The current study outlined the development and preliminary evaluation of a CBT-context-based social competence training for ASD (CBT-CSCA) developed in Hong Kong for Chinese adolescents with ASD. Twenty-five adolescents (aged 12-17 years, with a FSIQ above 80) were recruited. Significant improvements in social competence, autistic symptoms and general psychopathology at post-training and 3-month follow-up were reported by the parents. The study provided initial evidence support to the applicability of social competence training for adolescents with ASD in a different culture.

    DOI: https://doi.org/10.1016/j.chb.2018.02.025 

    Abstract: Social robots are foreseen to be a growing category of assistive devices for baby boomers in helping them live independently at home and in good health for longer. Artificial intelligence and speech recognition are making natural language user interfaces possible. Yet voices of social robots could influence users' preferences and perceptions in ways that have not been widely explored yet, let alone in Chinese-speaking context. A quantitative study was conducted to probe what voice characteristics of social robots baby boomers may prefer and what personality traits they would associate with various pitch, speech rate, and intonation in Mandarin. While the findings coincide with previous research in that female, extroverted voices were preferred by most participants, many individual differences remain, which could be attributed to differences in demographics, lifestyles, and personality traits. This study contributes to design decisions that would take individual differences into consideration. Social robots that could learn and adapt to people's preferences, perceptions, as well as the tasks at hand may fare better than a one-size-fits-all approach. We believe that voice user interfaces will play a key role in elderly people's initial acceptance and continuing engagement of social robots.

    Abstract: Three studies were conducted to determine whether outgroups were dehumanized through animalization since childhood. Using the Implicit Association Test (IAT), in Study 1 we found faster reaction times in the compatible condition (ingroup names and human words, outgroup names and animal words), compared with the incompatible condition (ingroup names and animal words, outgroup names and human words). In Study 2, we used a paper-and-pencil design and found that the association between animal-related words and outgroups was more prevalent in comparison to ingroups. The participants of Study 3 selected a larger number of animal-related words to describe the outgroups than their own groups. Results revealed that the tendency to animalize is a process that begins during early childhood. (PsycINFO Database Record (c) 2018 APA, all rights reserved) zitiert von 1

    Abstract: Over the past several decades, there has been increased interest in culture and children’s peer relationships. The findings from various research programs have clearly indicated that cultural contexts play a significant role in shaping children’s experiences in peer interactions and relationships. Cultural beliefs and values provide guidance for how peers judge and evaluate specific behaviors that children display in interactions. Social judgments and evaluations, in turn, serve to regulate children’s behaviors and eventually affect their developmental outcomes. In addition to social evaluation and regulation processes, culture determines, in part, the features and functions of dyadic and group relationships. In this chapter, we review and discuss the issues involved in the study of cultural diversity as it relates to peer interactions and relationships. The main theme of the chapter is the understanding of cultural involvement in the organization of peer relationsh ips. We first discuss various theoretical issues concerning cultural values, children’s social functioning, and peer relationships. Then we review the literature on children’s social behaviors in peer interactions in different cultural contexts. In the following sections, we review and discuss how cultural factors may be involved in determining the structural and functional features of friendships, peer groups, and popularity. Our chapter concludes with a discussion of future directions in the study of culture and peer relationships. (PsycINFO Database Record (c) 2018 APA, all rights reserved) zitiert von 42

    Abstract: Shyness refers to anxious reactivity in challenging social situations. Whereas shyness is believed to be biologically rooted, individual socialization experiences play a role in shaping its development. In this paper, I discuss issues related to culture, different forms of shyness, and adjustment. Cultural beliefs and values, particularly those related to socialization goals, are reflected in adults' and peers' attitudes toward children's shy behavior, which ascribe meaning to the behavior and, at the same time, regulate its development. Culture also determines, in part, the functional significance of shyness in terms of its relations with adjustment. It will be important to investigate the mediating role of social processes, such as evaluations and responses in peer interactions, in cultural influence on the display and developmental patterns of shyness. It will also be important to examine the implications of social and cultural changes for the development of shyness. ( PsycINFO Database Record (c) 2018 APA, all rights reserved)

  • Chen, Xinyin (2018): Culture, temperament, and social and psychological adjustment. In: Developmental Review, S. 42-53. DOI: 10.1016/j.dr.2018.03.004

    Abstract: Relative to personality and many behavioral attributes, temperament is believed to be determined to a greater extent by genetic and other biological factors. Nevertheless, personal and social experiences are involved in temperamental development. In this paper, I discuss issues related to culture, temperament, and adjustment mainly from a contextual-developmental perspective, which emphasizes the role of social evaluation processes in bridging culture and temperamental development. The review of the research findings indicates that cultural beliefs and values, particularly those related to socialization goals, are reflected in parents’ and peers’ attitudes toward children’s temperamental characteristics, such as reactivity in challenging situations and self-control and its behavioral manifestations. Culturally guided social attitudes contribute to variations in the display of temperamental characteristics among children across societies. Moreover, culture plays a role in shaping the functional meanings or significance of temperamental characteristics in human development. Researchers need to investigate in the future cultural issues in temperamental development, especially relations between temperament and adjustment in different contexts, using a multi-level and multi-method approach.

    Abstract: The Moral Psychology of Anger is the first comprehensive study of the moral psychology of anger from a philosophical perspective. In light of the recent revival of interest in emotions in philosophy and the current social and political interest in anger, the editors explain its resilience in our emotional lives and normative frameworks, and examine what inhibits and encourages thoughts, feelings, and expressions of anger. This volume also examines the ways in which rage--anger's cousin--is a moral emotion, what black rage is and how it is policed in our society and how berserker rage is limited and problematic for the contemporary military.

    Abstract: This chapter examines psychological and philosophical traditions in the study of values. It explores two perspectives on values that are useful for thinking about their role in understanding what it means to be human. The internal perspective focuses on the roles values play in the psychological functioning of people and how they relate to human essence. The external perspective describes how values are produced and acquired both in phylogenesis and in ontogenesis and how that contributes to human essence. It is suggested that the phylogenetic perspective explains the pan-cultural agreement in value hierarchies and the ontogenetic perspective explains both the assimilation of the cultural system of values and inter-individual diversity. The chapter also considers relations between personality and values and the metaphysical interpretation of values. Finally, it reflects on the relevance of values to human essence.

    DOI: https://doi.org/10.1016/j.trf.2018.07.017 

    Abstract: Many studies have consistently found evidence of aging-related navigation difficulties that lead to disorientation behaviors and/or reduced travel. Despite technological advances, older pedestrians mainly use paper maps to find their way in unknown environments while they have a lot of difficulties in using and interacting with them efficiently. In this context, the present study was aimed at assessing the effectiveness and acceptability and study older pedestrian’s behavior when wearing a vibrotactile instructions to help them finding their way in an unknown city as compared with visual instructions provided by a paper map. Fifty-eight participants (20 young adults ages 21–45, 20 younger-old adults ages 61–70, and 18 older-old adults ages 71–80) took part in a simulated navigation task where participants had to go from point A to point B in a virtual city. The task was performed either with a vibrotactile wristband delivering directional messages or with a standard paper map showing the visual instructions to follow. The data showed that vibrotactile guidance instructions improved the correct numbers of turns taken (left/right) at simple intersections. They also reduced travel time as compared with visual guidance instructions provided by a paper map. These benefits were greater among the older-old participants, who had trouble using the paper map and thus benefited greatly from the assistance provided by the vibrotactile guidance instructions. These findings suggest that such an assistance device using simple haptic guidance messages is able to improve older pedestrians’ mobility.

    Abstract: We develop a model of factors that enable morally courageous actors to carry on even after encountering organizational opposition. The model specifies that durable moral courage facilitates continued moral action and that demoralization inhibits it, and presents the perceived manageability of the organizational response as a factor affecting the extent to which an actor experiences durable moral courage and/or demoralization. It is proposed that moral efficacy, hardiness, and planning for endurance insulate the actor before an act of moral courage, by enhancing the perceived manageability of the organizational response; and that emotional self-regulation fortifies the actor by enhancing the perceived manageability of that response once it comes. It is also posited that moral efficacy and hardiness contribute directly to durable moral courage, hardiness and planning for endurance increase durable moral courage by promoting moral efficacy, and emotional self-regulation augments planning for endurance. Implications for research and practice are offered. zitiert von: 2
