Maintaining the safety of the human is a major concern in factories where humans co-exist with robots and other physical tools. Typically, the area around the robots is monitored using lasers. However, lasers cannot distinguish between human and non-human objects in the robot’s path. Stopping or slowing down the robot when non-human objects approach is unproductive. This research contribution addresses that inefficiency by showing how computer-vision techniques can be used instead of lasers which improve up-time of the robot.

A computer-vision safety system is presented. Image segmentation, 3D point clouds, face recognition, hand gesture recognition, speed and trajectory tracking and a digital twin are used. Using speed and separation, the robot’s speed is controlled based on the nearest location of humans accurate to their body shape. The computer-vision safety system is compared to a traditional laser measure. The system is evaluated in a controlled test, and in the field.

Computer-vision and lasers are shown to be equivalent by a measure of relationship and measure of agreement. R² is given as 0.999983. The two methods are systematically producing similar results, as the bias is close to zero, at 0.060 mm. Using Bland–Altman analysis, 95% of the differences lie within the limits of maximum acceptable differences.

In this paper an original model for future computer-vision safety systems is described which is equivalent to existing laser systems, identifies and adapts to particular humans and reduces the need to slow and stop systems thereby improving efficiency. The implication is that computer-vision can be used to substitute lasers and permit adaptive robotic control in human–robot collaboration systems.

Human language is entangled with the world we inhabit; through language we construct meaning and communicate about complex human endeavours, relationships and values. But what happens when life displaces people from these familiar meaning-making boundaries?

In this chapter, I describe my work with parents facing a child being diagnosed with Dravet Syndrome, a rare, chronic genetic disease that affects the development of the brain. Families faced with such a diagnosis are left confused and bewildered, unable to call upon familiar resources; even familiar words lose their meaning. ‘It is as if my life had been broken into a 1000 pieces and that from each piece the image had disappeared’, said one parent.

Working as an anthropological researcher, I used clean language interviews to gain deep insight into, and help make visible, these parents' experience. I explain how I stumbled over a number of difficulties in my use of clean language interviewing and how I learned to be creative in order to gain access to what had initially remained hidden in this overwhelming experience. In particular I highlight the value of allowing the interviewee to use me as a temporary ‘body map’ for feelings that appeared too difficult to hold in their own body.

This research enabled me to construct a model of how parents can navigate this experience and to create a facilitation program that is being used to support many such families.

This article addresses the critical need for exceptional leaders to shepherd the nationʼs Historically Black Colleges and Universities (HBCUs) in a post-Brown era where African American students enjoy unlimited access to higher education in the United States. The article spotlights the many contributions Black colleges and universities have made to American society against insuperable odds since their inception in the mid-nineteenth century. It studies selected examples of HBCUs whose graduates have distinguished themselves in areas where other institutions enjoy centers of excellence. The article traces the historical inequities between major and minority institutions, the challenges HBCUs face in surmounting these disparities, and the growing tendency of Black students to exercise their options by enrolling at White colleges and universities. With the loss of a pure monopoly on African American students, Black colleges now must find leaders of exceptional talent and vision in order to ensure their survival. The article recommends strategies designed to surmount hurdles and enhance the viability of Black colleges and universities in an increasingly competitive environment.

Over the years we have reported prosecutions where the defence has alleged, and with circumstantial support that the presence of a harmful foreign body in food was deliberate through the action of a single disgruntled employee or where the labour relations climate generally has been bad. It makes no difference to the manufacturer's responsibility—the offence is an absolute one—but occasionally courts have allowed it in mitigation. Sometimes, it has been the nature of the extraneous material, e.g. fragments of glass or metal, the like of which did not exist in the factory premises or plant. This may be taken as a symptom of the vandalism of the age, but more recently, two incidents have drawn attention to its dangers and provided a glimpse of the criminal mind which can inflict such injury on employers, and expose innocent consumers, of all ages, to possible harm.

Anthropologists have long discussed the ways in which their discipline has been entangled, consciously and unconsciously, with the colonized populations they study. A foundational text in this regard was Michel Leiris' Phantom Africa (L'Afrique fantôme; Leiris, 1934), which described an African ethnographic expedition led by Marcel Griaule as a form of colonial plunder. Leiris criticized anthropologists' focus on the most isolated, rural, and traditional cultures, which could more easily be described as untouched by European influences, and he saw this as a way of disavowing the very existence of colonialism. In 1950, Leiris challenged Europeans' ability even to understand the colonized, writing that “ethnography is closely linked to the colonial fact, whether ethnographers like it or not. In general they work in the colonial or semi-colonial territories dependent on their country of origin, and even if they receive no direct support from the local representatives of their government, they are tolerated by them and more or less identified, by the people they study, as agents of the administration” (Leiris, 1950, p. 358). Similar ideas were discussed by French social scientists throughout the 1950s. Maxime Rodinson argued in the Année sociologique that “colonial conditions make even the most technically sophisticated sociological research singularly unsatisfying, from the standpoint of the desiderata of a scientific sociology” (Rodinson, 1955, p. 373). In a rejoinder to Leiris, Pierre Bourdieu acknowledged in Work and Workers in Algeria (Travail et travailleurs en Algérie) that “no behavior, attitude or ideology can be explained objectively without reference to the existential situation of the colonized as it is determined by the action of economic and social forces characteristic of the colonial system,” but he insisted that the “problems of science” needed to be separated from “the anxieties of conscience” (2003, pp. 13–14). Since Bourdieu had been involved in a study of an incredibly violent redistribution of Algerians by the French colonial army at the height of the anticolonial revolutionary war, he had good reason to be sensitive to Leiris' criticisms (Bourdieu & Sayad, 1964). Rodinson called Bourdieu's critique of Leiris' thesis “excellent’ (1965, p. 360), but Bourdieu later revised his views, noting that the works that had been available to him at the time of his research in Algeria tended “to justify the colonial order” (1990, p. 3). At the 1974 colloquium that gave rise to a book on the connections between anthropology and colonialism, Le mal de voir, Bourdieu called for an analysis of the relatively autonomous field of colonial science (1993a, p. 51). A parallel discussion took place in American anthropology somewhat later, during the 1960s. At the 1965 meetings of the American Anthropological Association, Marshall Sahlins criticized the “enlistment of scholars” in “cold war projects such as Camelot” as “servants of power in a gendarmerie relationship to the Third World.” This constituted a “sycophantic relation to the state unbefitting science or citizenship” (Sahlins, 1967, pp. 72, 76). Sahlins underscored the connections between “scientific functionalism and the natural interest of a leading world power in the status quo” and called attention to the language of contagion and disease in the documents of “Project Camelot,” adding that “waiting on call is the doctor, the US Army, fully prepared for its self-appointed ‘important mission in the positive and constructive aspects of nation-building’” a mission accompanied by “insurgency prophylaxis” (1967, pp. 77–78). At the end of the decade, Current Anthropology published a series of articles on anthropologists’ “social responsibilities,” and Human Organization published a symposium entitled “Decolonizing Applied Social Sciences.” British anthropologists followed suit, as evidenced by Talal Asad's 1973 collection Anthropology and the Colonial Encounter. During the 1980s, authors such as Gothsch (1983) began to address the question of German anthropology's involvement in colonialism. The most recent revival of this discussion was in response to the Pentagon's deployment of “embedded anthropologists” in Afghanistan and elsewhere in the Middle East. The “Network of Concerned Anthropologists” in the AAA asked “researchers to sign an online pledge not to work with the military,” arguing that they “are not all necessarily opposed to other forms of anthropological consulting for the state, or for the military, especially when such cooperation contributes to generally accepted humanitarian objectives … However, work that is covert, work that breaches relations of openness and trust with studied populations, and work that enables the occupation of one country by another violates professional standards” (“Embedded Anthropologists” 2007).³ Other disciplines, notably geography, economics, area studies, and political science, have also started to examine the involvement of their fields with empire.⁴
