Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

This study aims to detect the main factors impeding the anti-female genital mutilation (FGM) efforts in Egypt post the January 25 revolution, with a special focus on the era of president El-Sisi. The purpose of this paper is to explain the reasons behind the continuation of violence against women in Egypt, namely, FGM, in light of the patriarchal structures and the state willingness to address that challenge.

Design/methodology/approach

The study utilizes a qualitative methodology. The study embarks on in-depth semi-structured interviews with 23 participants who experienced FGM and nine key informants from medical, religious, political and civil society backgrounds, including a professor of pathology, a gynecologist, a diplomatic researcher in Al-Azhar, three members of parliament, a representative of the Ministry of Population, the reporter of the National Council for Women and a representative of Nazra non-governmental organization for feminist studies in Egypt.

Findings

The findings reveal that FGM remains prevalent not only due to the persisting socio-cultural context that continues to embrace and reproduces gender inequalities, but also because of the insufficient political will to combat FGM and enforce the required laws.

Social implications

FGM is considered one form of gender inequality perpetuated by social, cultural and economic structures. It is recognized internationally as a crime and a violation against women’s rights as per the Universal Declaration of Human Rights, the Convention on the Elimination of All Forms of Discrimination against Women, the Convention on the Rights of the Child, etc. Although the Egyptian Government passed laws banning the practice of FGM, it continues to form a challenging problem to social workers, women activists, human rights groups and public health officials.

Originality/value

Little work has been done to investigate FGM post the January 25 revolution in Egypt and identify the main factors impeding the anti-FGM efforts in Egypt. This work fills this gap and concludes with some lessons learnt to fight FGM and improve the anti-FGM efforts.
