Abstract
Purpose
This study aims to explore the overlap between symptoms of depression, anxiety, irritability and aggressiveness in autism spectrum disorder (ASD), to measure specific and idiosyncratic emotional responses.
Design/methodology/approach
A total of 42 high functioning adolescents and adults, between 12 and 39 years old, meeting the diagnostic and statistical manual of mental disorders – 5 criteria for ASD were selected from the InFoR Autism cohort. Data were analyzed in an exploratory way using Hill and Smith and K-medoids cluster analysis.
Findings
The authors found an aggregation of anxiety, depression, aggressive behaviors and irritability. Cluster analysis was maximized for two groups with 17 and 25 participants, respectively. The first group was characterized by high levels of symptoms of irritability, aggressiveness, hyperactivity and intermediate levels of anxiety and depression. In the first group, participants had significantly higher levels of autistic symptoms considering the social responsiveness scale and repetitive behavior scale-revised scales (relatives’ reports) suggesting that a particular group of subjects with a high level of ASD specific symptoms may express anxiety and depression in a specific way based on externalizing behaviors in addition to the common mood and anxiety symptoms.
Research limitations/implications
Improved understanding of the aggregation of externalized symptoms with symptoms of anxiety and mood disorders in ASD should lead to a better understanding of the underlying mechanisms related to emotion dysregulation in ASD.
Practical implications
Improved knowledge of the symptoms could lead to enhanced detection of psychiatric comorbidities in ASD.
Originality/value
The study was based on a transdiagnostic approach of psychiatric symptoms in individuals with ASD. Aggregation and clustering analysis was used to explore naive patterns of these psychiatric symptoms.

Abstract
The archives of François Perroux deposited at IMEC bear witness to the fact that he has devoted, beyond his scientific production, great energy to the most material aspects of research: setting up and maintaining networks to publicize his work and that of other economists, either directly or through the institutes and the journals he headed; organize seminars and symposiums; take care of relations with colleagues and the press; create collections and journals; and so on.
In this chapter, we concentrate our attention on the archives relating to the management of the institutes, those attesting to the lines and themes of the producer’s research, and those concerning his important correspondence.
Thanks to the archives deposited at IMEC, it is possible to follow the development of the theoretical work of François Perroux by contextualizing it. They also show the itinerary of a Christian intellectual, whose attachment to social Catholicism constitutes a guiding thread and is reflected in all his activities. Finally, the archives illuminate his substantial role in the institutionalization of research in economics in the France of the twentieth century.

Abstract
The trajectory of François Perroux across the Vichy regime poses about all possible range of methodological issues to the historian of ideas: individual versus collective biography, ideational versus ideological reading, internal versus external analysis, etc. The chapter outlines key elements about Perroux’s trajectory showing the entanglements and boundaries of science and politics in the transition from democratic to authoritarian rule and vice versa. A particular emphasis on uncertainties and adjustments shows, against the tendency to a teleological explanation induced by a linear interpretation of his career, that different paths were considered by Perroux, but that his choices were nevertheless constrained by the forces of both the scientific and political fields.

Abstract
This chapter aims to address the question of the evolution of economists’s reception of Marxism in France, and thus to complete the more general history of the development of Marxism among French academics. To do so, we follow the relationship to Marx’s work of the economist François Perroux, a priori typical of the reversal reception of Marxist ideas in the 1950s, moving from open hostility to enthusiasm. Indeed, an incisive critic of Marx’s writings before the war, then head of the scientific institution of the Vichy regime, Perroux became in the postwar period a leading figure in the diffusion of Marx’s ideas in France. He founded the ISMEA (Institute of Mathematical and Applied Economic Sciences) which published the journal Études de marxologie, and eventually penned the preface to Marx’s economic works in 1963 for the Pléiade. By following this sinuous path, we show that the way Perroux related to Marx’s work helps us shed light on the various shifts in Perroux’s relationship to the science and politics of his time.

Abstract
In this chapter I will elaborate on Professor Jean-François Hennart’s impressive career in honour of him receiving the 2012 Booz & Co./Strategy+Business Eminent Scholar in International Management award. I will first present a sevenfold typology of his publications, classifying them into (1) conceptual studies on why multinational enterprises (MNEs) exist and use specific entry modes, (2) industry-focused case studies, (3) statistical studies of foreign entries, (4) review studies of entry mode choice, (5) country-level studies of international business activity, (6) conceptual studies scrutinizing multinationality-performance research, and (7) studies of emerging-market MNEs. I will then point out some of his qualities that in my view have contributed to his scholarly success. I will also describe the main academic and practical contributions of his work, and finish with a short conclusion.

Abstract
The chapter analyzes François Perroux’s institutional and intellectual activities under the Vichy regime (1940–1944) mainly by drawing on archival insights from Perroux’s papers. The authors argue that Perroux used his strategic position as general secretary of the Carrel Foundation (created by Marshal Pétain) to reshape French economics along a twofold trend: unifying economics with other social sciences, on the one hand; and developing its most analytical aspects, on the other hand. Thus, Perroux seized the opportunity to push for the introduction and dissemination of foreign theoretical studies within French economics, quite counter-intuitively to the expected nationalistic fallback accompanying authoritarian rule. In the end, the Vichy regime proved a suitable vehicle for the advancement of Perroux’s ideas and career: he managed in fact to make the best of a highly uncertain situation in 1940 and especially in 1944, with the impending Liberation of France. The authors show that Perroux used different strategies to neutralize those aspects of his work associated to Vichy’s ideology.

Abstract
Purpose
The purpose of this paper is to examine the effect of subjective ambivalence on ethical consumption behaviors and the role of ethical claims in reducing feelings of ambivalence toward buying ethical products.
Design/methodology/approach
The authors conducted two studies. In study 1, the authors carried out an online survey with a sample of 230 French consumers. The authors applied structural equation modeling with Amos to test the relationships among skepticism, ambivalence and ethical consumption behaviors. Study 2 is an experimental design in which the authors manipulated ethical claims (low – few ethical arguments vs. high – many ethical arguments) in advertising (176 French panelists). The authors tested the relationships among consumer ethical sensitivity, perceived brand ethicality, skepticism, ambivalence and intention to purchase an ethical product, depending on ethical claims in advertising.
Findings
Study 1 shows that skepticism toward advertising of ethical products amplifies feelings of ambivalence and that ambivalence reduces consumers’ willingness to adopt ethical consumption behaviors. Study 2 shows that strong claims in advertising of ethical products reduce skepticism toward advertising of ethical products and feelings of ambivalence toward buying an ethical product through perceived brand ethicality, with consumers’ ethical sensitivity positively moderating these relationships.
Research limitations/implications
The two studies explore only one form of ambivalence (i.e. subjective), and the experimental study focuses on a single category of products.
Practical implications
The findings highlight the difficulties in promoting ethical products. Consumers need to know if a product is “really” ethical, as they may feel ambivalent toward that product. This paper shows that strong ethical claims in advertising ethical products significantly help to overcome this barrier.
Originality/value
Based on attribution theory and persuasion models, this research reveals how ethical claims in advertising affect feelings of ambivalence, which negatively influence consumers’ willingness to adopt ethical consumption. In addition, it follows a holistic approach to ethical consumption behaviors to explore consumers’ ambivalence.

Abstract
We discuss Professor Jean-François Hennart’s key contributions to international strategic management theory, with a special focus on his integrative, 2009 Journal of International Business Studies article, ‘Down with MNE-centric theories! Market entry and expansion as the bundling of MNE and local assets’. In Hennart’s (2009) model, complementary assets co-determine the MNE’s initial entry mode choice and the subsequent evolution of the MNE foreign operations’ governance. Hennart (2009) describes this perspective on MNE governance as one based on asset bundling. We focus on the paper’s conceptual insights and discuss how Hennart’s model of foreign market entry informs managerial practice in the realm of international strategy.

Abstract
Purpose
This research paper aims to optimize the calibration process for an ABB IRB 120 robot, specifically for robotic orbital milling applications, by introducing and validating the use of the observability index and telescopic ballbar for accuracy enhancement.
Design/methodology/approach
The study uses the telescopic ballbar and an observability index for the calibration of an ABB IRB 120 robot, focusing on robotic orbital milling. Comparative simulation analysis selects the O3 index. Experimental tests, both static and dynamic, evaluate the proposed calibration approach within the robot’s workspace.
Findings
The proposed calibration approach significantly reduces circularity errors, particularly in robotic orbital milling, showcasing effectiveness in both static and dynamic modes at various tool center point speeds.
Research limitations/implications
The study focuses on a specific robot model and application (robotic orbital milling), limiting generalizability. Further research could explore diverse robot models and applications.
Practical implications
The findings offer practical benefits by enhancing the accuracy of robotic systems, particularly in precision tasks like orbital milling, providing a valuable calibration method.
Social implications
While primarily technological, improved robotic precision can have social implications, potentially influencing fields where robotic applications are crucial, such as manufacturing and automation.
Originality/value
This study’s distinctiveness lies in advancing the accuracy and precision of industrial robots during circular motions, specifically tailored for orbital milling applications. The innovative approach synergistically uses the observability index and telescopic ballbar to achieve these objectives.
