La trata de seres humanos y la cultura legal

[Resumen] Este artículo tiene por objeto analizar el Protocolo para Prevenir, Reprimir y Sancionar la Trata de Personas. En la primera parte, se ofrece una discusión crítica sobre el carácter deficitario de las medidas adoptadas para lidiar con el problema social de la trata de seres humanos. A continuación, se analizarán las dos narrativas que compiten en este problema y la forma en las que se responde a esta circunstancia; se explica la necesidad de aprender más sobre los intereses y valores que condicionan la aplicación de la ley. En la última parte, se discute sobre la relevancia potencial de la idea de la “cultura legal” para explicar los patrones de la ley en acción en distintos países y por diferentes agencias. El objetivo general de este artículo es mostrar la existencia de un vínculo entre la forma en la cual el problema de la trata es definido socialmente en la práctica y el rol de la cultura legal a la hora de darle forma a este vínculo.[Abstract] This Article discusses the Palermo Protocol to Prevent, Suppress and Punish Trafficking in Persons. In the first part it offers a critical discussion of what is entailed by speaking of a “shortfall” of enforcement in dealing with the social problem of human trafficking. It then goes on to show that there are two competing narratives of this problem and of the way it is being responded to, and explains why we need to learn more about the interests and values that condition the “law in action.” In the last section the Article discusses the potential relevance of the idea of the “legal culture” for explaining the patterns of “law in action” in different countries and different agencies. The Article’s overall aim is to show the existence of a link between the manner in which the problem of trafficking is socially defined in practice, and the role of legal culture in shaping this link

Using the concept of legal culture

Discusses the problems with the concept of legal culture and offers the challenge of explaining italian court delays as a case study of the difficulties and benefits of using the concept

Thrombin-induced events in non-platelet cells are mediated by the unique proteolytic mechanism established for the cloned platelet thrombin receptor.

We recently isolated a cDNA clone encoding a functional platelet thrombin receptor that defined a unique mechanism of receptor activation. Thrombin cleaves its receptor's extracellular amino terminal extension, unmasking a new amino terminus that functions as a tethered peptide ligand and activates the receptor. A novel peptide mimicking this new amino terminus was a full agonist for platelet secretion and aggregation, suggesting that this unusual mechanism accounts for platelet activation by thrombin. Does this mechanism also mediate thrombin's assorted actions on non-platelet cells? We now report that the novel thrombin receptor agonist peptide reproduces thrombin-induced events (specifically, phosphoinositide hydrolysis and mitogenesis) in CCL-39 hamster lung fibroblasts, a naturally thrombin-responsive cell line. Moreover, these thrombin-induced events could be recapitulated in CV-1 cells, normally poorly responsive to thrombin, after transfection with human platelet thrombin receptor cDNA. Our data show that important thrombin-induced cellular events are mediated by the same unusual mechanism of receptor activation in both platelets and fibroblasts, very likely via the same or very similar receptors

Inhibitory Plasticity in Auditory Cortex

Arguably the most important property of neuronal circuits in general, and of cortical circuits in particular, is plasticity—the ability to change in response to past experience. While many studies of plasticity emphasize changes in excitatory transmission, in this issue of Neuron, Galindo-Leon et al. demonstrate the important role that increased inhibition may play in shaping cortical responses to behaviorally relevant stimuli

Thermally driven circulation

Submitted in partial fulfillment of the requirements for the degree of Doctor of Science at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution August 1987Several problems connected by the theme of thermal forcing are addressed herein. The main topic is the stratification and flow field resulting from imposing a specified heat flux on a fluid that is otherwise confined to a rigid insulating basin. In addition to the traditional eddy viscosity and diffusivity, turbulent processes are also included by a convective overturning adjustment at locations where the local density field is unstable. Two classes of problems are treated. The first is the large scale meridional pattern of a fluid in an annulus. The detailed treatment is carried out in two steps. In the beginning (chapter 2) it is assumed that the fluid is very diffusive, hence, to first approximation no flow field is present. It is found that the convective overturning adjustment changes the character of the stratification in all the regions that are cooled from the top, resulting in a temperature field that is nearly depth independent in the northernmost latitudes. The response to a seasonal cycle in the forcing, and the differences between averaging the results from the end of each season compared to driving the fluid by a mean forcing are analyzed. In particular, the resulting sea surface temperature is warmer in the former procedure. This observation is important in models where the heat flux is sensitive to the gradient of air to sea surface temperatures. The analysis of the problem continues in chapter 5 where the contribution of the flow field is included in the same configuration. The dimensionless parameter controlling the circulation is now the Rayleigh number, which is a measure of the relative importance of gravitational and viscous forces. The effects of the convective overturning adjustment is investigated at different Rayleigh numbers. It is shown that not only is the stratification now always stable, but also that the vigorous vertical mixing reduces the effective Rayleigh number; thereby the flow field is more moderate, the thermocline deepens, and the horizontal surface temperature gradients are weaker. The interior of the fluid is colder compared to cases without convective overturning, and, because the amount of heat in the system is assumed to be fixed, the surface temperature is warmer. The fluid is not only forced by a mean heat flux, or a seasonally varying one, but its behavior under permanent winter and summer conditions is also investigated. A steady state for the experiments where the net heat flux does not vanish is defined as that state where the flow field and temperature structure are not changing with time except for an almost uniform temperature decrease or increase everywhere. It is found that when winter conditions prevail the circulation is very strong, while it is rather weak for continuous summer forcing. In contrast to those results, if a yearly cycle is imposed, the circulation tends to reach a minimum in the winter time and a maximum in the summer. This suggests that, depending on the Rayleigh number, there is a phase leg of several months between the response of the ocean and the imposed forcing. Differences between the two averaging procedures mentioned before are also observed when the flow field is present, especially for large Rayleigh numbers. The circulation is found to be weaker and the sea surface temperature colder in the mean of the seasonal realizations compared to the steady state derived by the mean forcing. As an extension to the numerical results, an analytic model is presented in chapter 4 for a similar annular configuration. The assumed dynamics is a bit different, with a mixed layer on top of a potential vorticity conserving interior. It is demonstrated that the addition of the thermal wind balance to the conservation of potential vorticity in the axially symmetric problem leads to the result that typical fluid trajectories in the interior are straight lines pointing downward going north to south. The passage of information in the system is surprisingly in the opposite sense to the clockwise direction of the flow. A model for water mass formation by buoyancy loss in the absence of a flow field is introduced in chapter 3. The idea behind it is to use the turbulent mixing parameterization to generate chimney-like structures in open water, followed by along-isopycnal advection and diffusion. This model can be applied to many observations of mode water. In particular, in this work it is related to the chimneys observed by the MEDOC Group (1970), and the Levantine Intermediate Water in the Eastern Mediterranean Basin. An analytic prediction of the depth of the water mass is derived and depends on the forcing and initial stratification. It suggests that the depth of shallow mode water like the 18°C water or the Levantine Intermediate Water would not be very sensitive to reasonable changes in atmospheric forcing. Similar conclusions were also reached by Warren (1972) by assuming that the temperature in the thermocline decreases linearly with depth, and by approximating the energy balance in a water column by a Newtonian cooling law

Music and the Auditory Brain: Where is the Connection?

Sound processing by the auditory system is understood in unprecedented details, even compared with sensory coding in the visual system. Nevertheless, we do not understand yet the way in which some of the simplest perceptual properties of sounds are coded in neuronal activity. This poses serious difficulties for linking neuronal responses in the auditory system and music processing, since music operates on abstract representations of sounds. Paradoxically, although perceptual representations of sounds most probably occur high in auditory system or even beyond it, neuronal responses are strongly affected by the temporal organization of sound streams even in subcortical stations. Thus, to the extent that music is organized sound, it is the organization, rather than the sound, which is represented first in the auditory brain

Signaling Conformity: Changing Norms in Japan and China

Whatever their differences, the articles in this issue also have much in common in addition to their regional focus. The author of this Comment shall discuss in turn three (related) theoretical issues that arise, to a greater or lesser degree, in all four contributions. The first Part of this Comment considers the insights of these articles on the need to move from discussing transplants to focusing on transnational legal processes. The second Part examines what the contributions tell us about culture, legal culture, and the so-called norm of conformity. I shall concentrate in particular on the cultural sources of choices to conform. The conclusion discusses the contribution of these articles toward the further study of the processes for spreading conformity. In the author’s view, the articles\u27 insights on these processes encompass many of their most valuable common elements. But, conversely, the significance of their claims can only be appreciated if placed in a larger framework
