We used a new method called “Ghost-in-the-Machine” (GiM) to investigate social interactions with a robotic bartender taking orders for drinks and serving them. Using the GiM paradigm allowed us to identify how human participants recognize the intentions of customers on the basis of the output of the robotic recognizers. Specifically, we measured which recognizer modalities (e.g., speech, the distance to the bar) were relevant at different stages of the interaction. This provided insights into human social behavior necessary for the development (...) of socially competent robots. When initiating the drink-order interaction, the most important recognizers were those based on computer vision. When drink orders were being placed, however, the most important information source was the speech recognition. Interestingly, the participants used only a subset of the available information, focussing only on a few relevant recognizers while ignoring others. This reduced the risk of acting on erroneous sensor data and enabled them to complete service interactions more swiftly than a robot using all available sensor data. We also investigated socially appropriate response strategies. In their responses,the participants preferred to use the same modality as the customer’s requests, e.g., they tended to respond verbally to verbal requests. Also, they added redundancy to their responses, for instance by using echo questions. We argue that incorporating the social strategies discovered with the GiM paradigm in multimodal grammars of human–robot interactions improves the robustness and the ease-of-use of these interactions, and therefore provides a smoother user experience.

Human–robot interactions are often affected by error situations that are caused by either the robot or the human. Therefore, robots would profit from the ability to recognize when error situations occur. We investigated the verbal and non-verbal social signals that humans show when error situations occur in human–robot interaction experiments. For that, we analyzed 201 videos of five human–robot interaction user studies with varying tasks from four independent projects. The analysis shows that there are two types of error situations: social (...) norm violations and technical failures. Social norm violations are situations in which the robot does not adhere to the underlying social script of the interaction. Technical failures are caused by technical shortcomings of the robot. The results of the video analysis show that the study participants use many head movements and very few gestures, but they often smile, when in an error situation with the robot. The results suggest that participants do not see the robot as a social interaction partner with comparable communication skills. Our findings have implications for builders and evaluators of human–robot interaction systems. The builders need to consider including modules for recognition and classification of head movements to the robot input channels. The evaluators need to make sure that the presence of an experimenter does not skew the results of their user studies. (shrink)

Greenwashing (GW) is a complex, dynamic, interdisciplinary, multidimensional, and multifaceted phenomenon. There are more theoretical than empirical studies on GW because of several difficulties in collecting accurate data and obtaining objective GW measures. After disentangling the multifaceted GW phenomenon by describing its main dimensions, this study provides a systematic methodological literature review on empirical research papers published from 1990 to 2022 in journals of Business, Management, and Accounting to understand how empirical researchers are operationalizing GW and how our methodological choices (...) affect our understanding of this phenomenon. Our results show that the actual GW operationalization is challenging and that scholars are highly uncertain about how such operationalization should be designed and implemented to provide an effective GW measurement instrument. Further, a growing number of studies investigate hypothetical GW cases adopting perception-based measures, while limited research explores real GW cases. (shrink)

English summary: The present work demonstrates the important influence of Heidegger on the philosophical thought of Walter Benjamin, on his philosophy of history, as well as his philosophy of art and language. Concentrating on the formative periods for both philosophers, the work examines their early education, as well as the interlacing of the philosophy of art and history in their concept of art. The final section treats works by both philosophers on the philosophy of art from their early years. French (...) description: L'objectif principal de ce livre est de demontrer de quelle maniere la lecture de certains textes de jeunesse de Heidegger marqua profondement la pensee philosophique de Benjamin. Celui-ci aurait subi l'influence heideggerienne aussi bien au niveau de sa propre philosophie de l'histoire que de sa philosophie du langage et de sa philosophie de l'art. Le fondement theorique est l'approche de la periode de formation, encore peu etudiee, des deux philosophes. La philosophie neokantienne est le principal courant philosophique a l'epoque dans toutes les universites allemandes. C'est pourquoi le point de depart de la recherche, notamment pour la premiere et la deuxieme partie (histoire et langage), se centre sur la formation des jeunes Benjamin et Heidegger aupres de maitres tels que Heinrich Rickert, Edmund Husserl et Emil Lask. L'entrecroisement de philosophie de l'histoire et de philosophie du langage aura une projection decisive dans le debat concernant le concept d'art chez les deux philosophes. Le troisieme axe d'etude porte quant a lui sur la philosophie de l'art. Il traite du livre de Heidegger date de 1929 sur Kant et le probleme de la metaphysique, et du texte de jeunesse de Benjamin intitule L'arc-en-ciel. Entretien sur l'imagination (1915). (shrink)

In A Centaur in Auschwitz, Massimo Giuliani sheds new light on Primo Levi's rational, demythologizing approach to suffering and survival. Whether working in narrative or poetic form, Levi grappled with the ambiguities and complexities of innocence and guilt, triumph and loss. This unique book, with its concise overview of Levi's expression and development as a writer, reveals Primo Levi for what he was: scientist, intellectual, Jew, and dedicated seeker of the roots of human dignity.

Il saggio presenta la definizione e l’interpretazione di Maimonide delle sette leggi noahidi come si trovano nel codice halakhico _Mishnè Torà, Hilkhot melakhim_, e come discusse ed elaborate dal pensatore ebreo contemporaneo (tedesco-americano) Steven S. Schwarzschild. Rispetto ad altre versioni rabbiniche, l’interpretazione di Maimonide aggiunge la condizione che l’osservanza di quelle leggi è valida solo se sono accettate e rispettate come leggi rivelate, non solo come _lex naturalis_. Su tale condizione esiste un disaccordo tra gli studiosi e i rabbini ebrei, (...) per esempio tra Marvin Fox e Aaron Lichtenstein (la loro posizione è un caso di studio presentato qui). Più specificamente, Schwarzschild argomenta a favore dell’interpretazione del Rambam e cerca di dimostrare che è coerente con la visione globale che Maimonide aveva dell’ebraismo in quanto tale. The essay presents Maimonides’ definition and interpretation of the seven Noahide laws as they are found in the halakhic code _Mishnè Torà, Hilkhot melakhim_, and as discussed and elaborated by the contemporary Jewish (German-American) thinker Steven S. Schwarzschild. In comparison with other rabbinical versions, Maimonides’ interpretation adds the condition that the observance of those laws is valid only if they are accepted and obeyed as revealed laws, not only as _lex naturalis_. About such a condition a disagreement exists among the Jewish scholars and rabbis, for example between Marvin Fox and Aaron Lichtenstein (their position is a case-study presented here). More deeply, Schwarzschild argues in favor of the Rambam’s interpretation and tries to demonstrate that it is consistent with the comprehensive vision Maimonides had on Judaism as such. (shrink)

L’interpretazione dei testi è il cuore del giudaismo e lo studio in ebraico della Torà scritta e orale è uno dei suoi precetti fondamentali. Ma interpretare è un’arte sviluppatasi sulla base di regole precise che fissano dei limiti logici e insieme potenziano la fantasia dei maestri di Israele. In questi dodici capitoli si esplorano tali middot o norme ermeneutiche, la dialettica tra senso letterale e approccio midrashico, gli sviluppi dell’esegesi rabbinica soprattutto in età medievale, i dibattiti sul valore delle aggadot (...) nella prima modernità e, infine, i diverbi tra ortodossia e riforma sul posto da assegnare al metodo storico-critico nella lettura dei testi sacri: Torà, Talmud, Zohar... Ma idee e prassi dell’interpretazione si applicano anche al mondo dei sogni, all’elaborazione della memoria e alla vasta produzione poetica e letteraria, rifiorita in ebraico nel corso del Novecento, in particolare nella società israeliana. Questo percorso mostra come, da sempre e mai come oggi, il giudaismo sia una interpreting tradition nel solco di una lunga storia che combina rigore e innovazione. Secondo il Midrash, Dio stesso, tracciando corone sulle lettere della Torà, ha cominciato questa storia. (shrink)

È possibile esporre e comprendere l’etica ebraica ‘stando su un piede solo’ ossia in poche e semplici formule? Non è piuttosto il giudaismo un cammino lungo e complesso, e dunque anzitutto halakhà, un insieme di norme tese a santificare la vita quotidiana e a rafforzare un’identità di popolo? Quali sono i nessi tra la sfera etica, di sua natura universale, e la sfera delle pratiche simbolico-rituali, che caratterizzano e rendono particolare lo stile di vita ebraico? Cosa dice poi il pensiero (...) rabbinico in merito all’etica del lavoro, o sulle attuali urgenze ecologiche, sull’esercizio del potere, sulla difesa dei diritti umani? In queste pagine la delicata questione del rapporto tra etica e halakhà viene indagata alla luce degli antichi dibattiti rabbinici fino alle discussioni contemporanee passando naturalmente attraverso la grande lezione etica di Maimonide. Uno studio affascinante e impegnativo, guidato dalla stella polare della giustizia, secondo il dettame della Torà: “La giustizia, la giustizia seguirai” (Deuteronomio 16,20). (shrink)

Presents a philosophical-theological approach to the Holocaust, which is considered both a break in the continuity of tradition and continuity within the break of modernity. Considers that both Jewish belief in God and Jewish identity are now at stake. Among the modern Jewish thinkers, accords significant attention to Fackenheim, while developing an original approach to Jewish theodicy.
