AbstractIn this paper, we present a robotic workcell for task automation in footwear manufacturing such as sole digitization, glue dispensing, and sole manipulation from different places within the factory plant. We aim to make progress towards shoe industry 4.0. To achieve it, we have implemented a novel sole grasping method, compatible with soles of different shapes, sizes, and materials, by exploiting the particular characteristics of these objects. Our proposal is able to work well with low density point clouds from a single RGBD camera and also with dense point clouds obtained from a laser scanner digitizer. The method computes antipodal grasping points from visual data in both cases and it does not require a previous recognition of sole. It relies on sole contour extraction using concave hulls and measuring the curvature on contour areas. Our method was tested both in a simulated environment and in real conditions of manufacturing at INESCOP facilities, processing 20 soles with different sizes and characteristics. Grasps were performed in two different configurations, obtaining an average score of 97.5% of successful real grasps for soles without heel made with materials of low or medium flexibility. In both cases, the grasping method was tested without carrying out tactile control throughout the task.

This paper presents a characterization of a crosslinked EVA residue (EVA-c) from expanded sheets used in the shoe industry and post-consumer urban-waste polyethylenes regarding their molecular (FTIR), mechanical (tensile and impact tests), morphological (SEM), thermal (DSC, TGA) and dynamic-mechanical (DMTA) properties. For comparison, the properties of the EVA-c and recycled polyethylenes are compared to respective virgin polymers. The recycled polyethylenes generally presented similar properties to the virgin ones. On the other hand, some EVA-c properties differed from virgin ones since it has a high degree of crosslinking and it therefore has a higher tensile modulus and lower elongation at break, notched Izod impact strength and hardness. Additionally, crosslinking was also found to modify the thermal properties (TGA and DSC) of EVA-c.

Proactive Monitoring

Evasion of labor market regulations in middle income countries is systemic. This is generally known as informality. In Latin America, where less than 50% of workers are registered with social security, this is a permanent phenomenon and encompasses a variety of economic realities ranging from subsistence self-employment to evasion of certain regulations including social security contributions. In this study we analyze the role of enforcement in curbing informality in large formal firms in Peru, where informality levels are around 70%. Through the Peruvian National Labor Control Superintendence (SUNAFIL) we randomly sent 697 letters to formal Peruvian firms of more than 50 workers, indicating their obligation to enroll workers in social insurance systems (health and pensions). Two types of letters were sent, one with a deterrence message and one emphasizing the benefits of formalization. One year after the letters were sent, we found a positive and statistically significant effect on the number of workers enrolled in social security (9.8% on average). Only strict deterrence messages had a significant impact, and only in very large firms. This evidence suggests that there is room for improvement in compliance with labor regulations through more proactive monitoring and behavioral tools such as reminders, but effects could be concentrated in the largest firms.

Resistance Data

Platform capitalism has enabled digital platforms to bring producers, consumers, and workers in a multisided marketplace with the purpose of collecting data. The resulting commodification of materiality and sociality in the digital sphere and the proprietary control of data open opportunities for value creation and realization, quite distinct from the value propositions of industrial manufacturing. As the relationship between value generation and human labor becomes tenuous or invisible, management strategies to appropriate value extends beyond labor control to direct appropriation. This article explores how labor responds to such devices of control and appropriation by digital platforms. Using the typological approach, the study argues that labor resistance emerges as a direct response to the management strategies of platforms in the form of granular resistance, data activism, trade unions and workers’ organization, and collective ownership.
