Even if for many years hemispheric asymmetries have been considered as a uniquely human feature, an increasing number of studies have described hemispheric asymmetries for various behavioral functions in several nonhuman species. An aspect of animal lateralization that has attracted particular attention has concerned the hemispheric asymmetries for emotions, but human and animal studies on this subject have been developed as independent lines of investigation, without attempts for their integration. In this perspective article, after an illustration of factors that have hampered the integration between human and animal studies on emotional lateralization, I will pass to analyze components and stages of the processing of emotions to distinguish those which point to a continuum between humans and many animal species, from those which suggest a similarity only between humans and great apes. The right lateralization of sympathetic functions (involved in brain and bodily activities necessary in emergency situations) seems consistent across many animal species, whereas asymmetries in emotional communication and in structures involved in emotional experience, similar to those observed in humans, have been documented only in primates.

Human joint action is inherently cooperative, manifested in the collaborative efforts of participants to minimize communicative trouble through interactive repair. Although interactive repair requires sophisticated cognitive abilities, it can be dissected into basic building blocks shared with nonhuman animal species. A review of the primate literature shows that interactionally contingent signal sequences are at least common among species of nonhuman great apes, suggesting a gradual evolution of repair. To pioneer a cross-species assessment of repair this paper aims at (i) identifying necessary precursors of human interactive repair; (ii) proposing a coding framework for its comparative study in humans and nonhuman species; and (iii) using this framework to analyse examples of interactions of humans (adults/children) and nonhuman great apes. We hope this paper will serve as a primer for cross-species comparisons on dealing with communicative breakdowns.

Abstract Behavioural lateralization, which reflects the functional specializations of the two brain hemispheres, is assumed to play an important role in cooperative intraspecific interactions. However, there are few studies focused on the lateralization in cooperative behaviours of individuals, especially in a natural setting. In the present study, we investigated lateralized spatial interactions between the partners in life-long monogamous pairs. The male-female pairs of two geese species (barnacle, Branta leucopsis, and white-fronted, Anser albifrons geese), were observed during different stages of the annual cycle in a variety of conditions. In geese flocks, we recorded which visual hemifield (left/right) the following partner used to monitor the leading partner relevant to the type of behaviour and the disturbance factors. In a significant majority of pairs, the following bird viewed the leading partner with the left eye during routine behaviours such as resting and feeding in undisturbed conditions. This behavioural lateralization, implicating the right hemisphere processing, was consistent across the different aggregation sites and years of the study. In contrast, no significant bias was found in a variety of geese behaviours associated with enhanced disturbance (when alert on water, flying or fleeing away when disturbed, feeding during the hunting period, in urban area feeding and during moulting). We hypothesize that the increased demands for right hemisphere processing to deal with stressful and emergency situations may interfere with the manifestation of lateralization in social interactions.

Abstract Can one speak philosophically of a justified limitation of freedom? Hegel’s logically founded definition of free will and his understanding of right and duty can contribute to a clarification of the concept of freedom. Important is a precise differentiation between freedom and caprice (Willkür) – the latter being a necessary but one-sided element of the free will. In caprice, the will is not yet in the form of reason. Rational rights and duties are not a restriction of freedom. Insofar as individual rights can collide (e. g. in emergency situations), there can be a temporary and proportionate restriction of certain rights in favour of higher rights, such as the right to life. Dictatorships are instances of capricious rule which restrict freedom; the rationally designed state, by contrast, restricts only caprice. What is tobe defined are the duties and the rights of the state and the duties and the rights of the citizens.

This article presents the conditions of transnational corporations’ activity in the period of aggravated situation associated with coronavirus infection. The activities of large multinational companies in such industries as digital electronics (“Apple”, “Intel”, “Qualcomm”), automotive (“General Motors”, “Ford”, “Toyota”), air transportation (“American Airlines”, “Delta Air Lines”, “United Airlines”, “Lufthansa” and “British Airways”) are revealed. A list of measures that contribute to a painless way out of the crisis for multinational companies is presented. It is proposed to create agencies based on a multinational company to make decisions in emergency situations, which should contribute to earlier detection of threats and quickly make the right management decisions. The role of potential risk assessment and implementation of emergency response mechanisms is described. There is a need to create a positive and active mechanism for exchanging information for employees, customers and suppliers, as well as the formation of standard communication documents. The importance of maintaining the physical and psychological health of employees and the need to analyze the nature of jobs for the adoption of appropriate recovery plans is determined. The article presents the importance for multinational companies in establishing plans to respond to supply chain risks. This will make it possible to manage inventory more effectively in the short term in the context of reduced consumption. It is proposed to pay special attention to solutions for identifying risks related to productivity and maintaining customer relationships caused by the inability to resume production in the short term. It is stated that multinational companies should create or modernize mechanisms for systematic risk management and control, identify the main risks in advance and develop plans to respond to them

Enteroviruses (EVs) are viruses of the family Picornaviridae that cause mild to severe infections in humans and in several animal species, including non-human primates (NHPs). We conducted a survey and characterization of enteroviruses circulating between humans and great apes in the Congo. Fecal samples (N = 24) of gorillas and chimpanzees living close to or distant from humans in three Congolese parks were collected, as well as from healthy humans (N = 38) living around and within these parks. Enteroviruses were detected in 29.4% of gorilla and 13.15% of human feces, including wild and human-habituated gorillas, local humans and eco-guards. Two identical strains were isolated from two humans coming from two remote regions. Their genomes were similar and all genes showed their close similarity to coxsackieviruses, except for the 3C, 3D and 5′-UTR regions, where they were most similar to poliovirus 1 and 2, suggesting recombination. Recombination events were found between these strains, poliovirus 1 and 2 and EV-C99. It is possible that the same EV-C species circulated in both humans and apes in different regions in the Congo, which must be confirmed in other investigations. In addition, other studies are needed to further investigate the circulation and genetic diversity of enteroviruses in the great ape population, to draw a definitive conclusion on the different species and types of enteroviruses circulating in the Republic of Congo.

Scholars of human–animal studies, literary criticism and art history have paid considerable attention of late to how the visual representation of nonhuman animals has often and sometimes to great effect been used in the imagining of national identity. It is from the scrutinies of these several disciplines that the broad backcloth of this article is woven. Its focus is the neglected coupling of patriotism and carnism, instantiated here by its deployment in William Hogarth’s painting Calais Gate (1749). A pro-animal reading is offered of the English artist’s exhortation that it is in the nature of ‘true-born Britons’ to consume a daily dish of roast beef served with lashings of francophobia and anti-popery. The article suggests that alert contemporary viewers of Calais Gate would nevertheless have noticed that Hogarth’s painterly triumphalism ironically rekindles the repressed memory of English military defeat and territorial loss. Because the political and religious borders between England and France were so easily defaced and refaced, the accompanying air of uncertainty over national identity would also have infiltrated the perceived authenticity of English roast beef. The article draws on animal rights theory, on nonspeciesist green criminology and on green visual criminology in order to oppose the historical dominance of human interests over those of other animal species in discourses of abuse, cruelty and harm.

Abstract Aprosodia is a deficit in comprehending or expressing variations in tone of voice used to express both linguistic and emotional information. Affective aprosodia refers to a specific deficit in producing or comprehending the emotional or affective tones of voice. Aprosodia is most commonly associated with right hemisphere strokes; however, it may also result from other types of brain damage such as traumatic brain injury. Although research investigating hemispheric lateralization of prosody continues, there is strong evidence that most aspects of affective prosody are directed by the right hemisphere. Disorders of emotional communication can have a significant impact on quality of life for those affected and their families. However, there has been relatively little research regarding treatment for this disorder. Recently, 14 individuals were treated for affective aprosodia using two treatments, one based on cognitive-linguistic cues and the other on imitation of prosodic modeling. Most of the participants responded to at least one of the two treatments, and a refinement of the treatments are currently underway. Because researchers are finding support for the hypothesis that expressive aprosodia can result from a motor deficit, the refined treatment incorporates principles of motor learning to enhance imitation of prosodic models, as well as cognitive-linguistic cues.

This study investigated two mechanism-based treatments for expressive aprosodia, a disturbance in emotional prosody thought to be governed by the right hemisphere. The 3 participants all suffered right CVA's resulting in expressive aprosodia. Presence of expressive aprosodia was determined by performance on two batteries of emotional communication. A single subject ABAC design was employed in which two treatments, one imitative and one cognitive linguistic, were assigned in random order. All participants in this study were randomly assigned to begin with the cognitive linguistic treatment. Probes of treated and untreated emotions were completed during baseline and therapy phases. Probe items were judged by a reliable, trained rater blind to time of testing. Visual and statistical analyses were completed. These analyses confirmed that both treatments were active. For example, effect size calculations confirmed modest to substantial treatment effects for both treatments in all 3 patients. Replication to increase confidence about treatment effect and enhance understanding of the neuromechanisms underlying aprosodia is underway. (JINS, 2004, 10, 786–793.)
