    Doe v. Nestle, S.A.: Chocolate and the Prohibition on Child Slavery

    Get PDF
    West Africa is presently home to approximately 1.5 million acres of cocoa farmland, which subsequently produces 70% of the world’s current chocolate supply. Côte d’Ivoire, also known as the Ivory Coast, is one of the largest cocoa producing countries within West Africa. The increase of farmland and the need to control the deteriorating conditions have always created a demand for farm workers. Regrettably, more than 1.5 million cocoa farm workers in West Africa are currently children. These child workers are exposed to hazardous dust, flames, smoke, and chemicals, are required to utilize dangerous tools that they are not properly trained to use, and are subject to various forms of physically demanding work. In the early 2000s, the Ivorian government ratified the International Labour Organization’s Convention Concerning the Prohibition and Immediate Action for the Elimination of the Worst Forms of Child Labour (Convention 182). The International Labor Rights Forum (ILRF), an organization that combats our world’s problems of worker’s rights and labor standards, decided to take legal action against companies who refused to follow protocols to eliminate the use of child slave labor on cocoa farms on the Ivory Coast. The ILRF partnered with several law firms across the nation, bringing forth causes of action under the Alien Tort Statute (ATS), the Torture Victim Protection Act (TVPA), and other state-related claims. Part II of this case note discusses the ATS, its legislative history, and the various noteworthy case law that has interpreted the statute over time. Part III will discuss the scope of aiding and abetting liability for violations of international law and part IV will discuss the procedural history and legal reasoning behind the decisions of Doe v. Nestle, S.A. over the past sixteen years of litigation. Finally, this note will conclude with a personal analysis and prediction regarding the next steps of this case

    Haptic induced motor learning and the extension of its benefits to stroke patients

    In this research, the Haptic Master robotic arm and virtual environments are used to induce motor learning in subjects with no known musculoskeletal or neurological disorders. It is found in this research that both perception and performance of the subject are increased through the haptic and visual feedback delivered through the Haptic Master. These system benefits may be extended to enhance therapies for patients with loss of motor skills due to neurological disease or brain injury. Force and visual feedback were manipulated within virtual environment scenarios to facilitate learning. In one force feedback condition, the subject is required to maneuver a sphere through a haptic maze or linear channel. In the second feedback condition, the subject\u27s movement was stopped when the sphere came in contact with the haptic walls. To resume movement, the force vector had to be redirected towards the optimal trajectory. To analyze the efficiency of the various scenarios, the area between the optimal and actual trajectories was used as a measure of learning. The results from this research demonstrated that within more complex environments one type of force feedback was more successful in facilitating motor learning. In a simpler environment, two out of three subjects experienced a higher degree of motor learning with the same type of force feedback. Learning is not enhanced with the presence of visual feedback. Also, in nearly all studied cases, the primary limitation to learning is shoulder and attention fatigue brought on by the experimentation

    Seasonality of Marriages and Ecological Contexts in Rural Communities of Central-Southern Italy (Abruzzo), 1500–1871

    Get PDF
    The seasonality of 27,705 marriages celebrated in a four century span in the Province of Teramo (Abruzzo, Italy) was analyzed to identify the presence of a long-term pattern related to the prevailing subsistence activity and the main factors affecting it. The results show general agreement in all centuries with the agricultural patterns of other lowland or south-central Italian groups (Piedmont, Veneto, Liguria, Emilia Romagna, Tuscany, Latium, Campania, Apulia) and Mediterranean regions (Spain, France), although with some differences. Religious factors strongly affected the timing of marriage only during Lent. Of interest is the progressive increase through the centuries of marriages in the summer-autumn months, associated with a decrease in January and February. This suggests the passage from a summer migration system to a rural sedentary system with occasional seasonal work

    Maternal mortality in 19th- and early 20th-century Italy

    Get PDF
    Although dramatically reduced in Western and developed countries, maternal mortality is still today one of the most relevant social and health scourges in developing countries. This is the reason why high levels of maternal mortality are always interpreted as a sign of low living standards, ignorance, poverty and woman discrimination. Maternal mortality represents, therefore, a very peculiar characteristic of demographic systems of ancien regime. Despite this important role in demographic systems, no systematic study has been addressed to investigate the impact of maternal mortality in historical Italy. The aim of this article is to shed some light on such a phenomenon by investigating its trend over time and the determinants in some Italian populations between the 18th and the early 20th centuries. The analysis will make use of civil and parish registers linked together by means of nominative techniques, and it will be, therefore, carried out at the micro level

    Experimental Tests of Conduction/Convection Heat Transfer in Very High Porosity Foams with Lattice Structures, Immersed in Different Fluids

    This experimental work presents the results of measurements of thermal conductivity lambda and convection heat transfer coefficient h on regular structure PLA and aluminium foams with low density ratio (similar to 0.15), carried out with a TCP (thermal conductivity probe), built by the authors' laboratory. Measurements were performed with two fluids, water and air: pure fluids, and samples with the PLA and aluminium foams immersed in both fluids have been tested. Four temperatures (10, 20, 30, 40 degrees C) and various temperature differences during the tests Delta T (between 0.35 and 9 degrees C) were applied. Also, tests in water mixed with 0.5% of a gel (agar agar) have been run in order to increase the water viscosity and to avoid convection starting. For these tests, at the end of the heating, the temperature of the probe reaches steady-state values, when all the thermal power supplied by the probe is transferred to the cooled cell wall; thermal conductivity was also evaluated through the guarded hot ring (GHR) method. A difference was found between the results of lambda in steady-state and transient regimes, likely due to the difference of the sample volume interested by heating during the tests. Also, the effect of the temperature difference Delta T on the behaviour of the pure fluid and foams was outlined. The mutual effect of thermal conductivity and free convection heat transfer results in being extremely important to describe the behaviour of such kinds of composites when they are used to increase or to reduce the heat transfer, as heat conductors or insulators. Very few works are present in the literature about this subject, above all, ones regarding low-density regular structures

    All-optical trapping and acceleration of heavy particles

    Full text link
    A scheme for fast, compact, and controllable acceleration of heavy particles in vacuum is proposed, in which two counterpropagating lasers with variable frequencies drive a beat-wave structure with variable phase velocity, thus allowing for trapping and acceleration of heavy particles, such as ions or muons. Fine control over the energy distribution and the total charge of the beam is obtained via tuning of the frequency variation. The acceleration scheme is described with a one-dimensional theory, providing the general conditions for trapping and scaling laws for the relevant features of the particle beam. Two-dimensional, electromagnetic particle-in-cell simulations confirm the validity and the robustness of the physical mechanism.Comment: 10 pages, 3 figures, to appear in New Journal of Physic
