A pirataria marítima e sua caracterização como ameaça: presença, tipo, armas, violência e navios atacados entre 1991 e 2019

Maritime piracy is a threat to maritime trade whose contemporary version has been legally addressed by the United Nations Convention on the Law of the Sea (UNCLOS) and International Maritime Organization (IMO) and coercively by the UN and EU. The present article analyzes maritime piracy from the Copenhagen School’s theoretical perspective and its application to the International Chamber of Commerce’s annual reports on piracy, whose information ranges from 1991 to 2019. This analysis indicates two increase periods, characterized by presence, type, arms, violence, and ships under attack.la piratería marítima es una amenaza para el comercio marítimo cuya versión contemporánea ha sido abordada legalmente por la Convención de las Naciones Unidas sobre el Derecho del Mar (CDM) y la Organización Marítima Internacional (OMI) y coercitivamente por la ONU y la UE.

An experimental test of prejudice about foreign people

This paper o¤ers two related issues: (i ) an applications of beliefs about the cooperative behavior of others to policy-oriented issues, (ii ) a method of explor- ing prejudices (toward others) where interviewees are oblivious of its purpose. We studied contributions and guesses about others?contributions through an experimental game. Prejudice is examined as an implicitly held belief by a Spanish college student towards any of the speci?ed foreign population groups (i.e. the Asians, the Africans, the Latin Americans and the Westerners). The results show that: at the individual level, there exists some subjects that harbor strong positive (and negative) prejudices toward the foreigners. The prejudice models ?tted also show that: own contributions, femaleness, individual wealth; and beliefs about income status, cultural status, religious intensity, societal co- operation and political orientation have strong in?uences on racial prejudice.Beliefs, Prejudice, Public Goods Game

OTOC, complexity and entropy in bi-partite systems

There is a remarkable interest in the study of Out-of-time ordered correlators (OTOCs) that goes from many body theory and high energy physics to quantum chaos. In this latter case there is a special focus on the comparison with the traditional measures of quantum complexity such as the spectral statistics, for example. The exponential growth has been verified for many paradigmatic maps and systems. But less is known for multi-partite cases. On the other hand the recently introduced Wigner separability entropy (WSE) and its classical counterpart (CSE) provide with a complexity measure that treats equally quantum and classical distributions in phase space. We have compared the behavior of these measures in a system consisting of two coupled and perturbed cat maps with different dynamics: double hyperbolic (HH), double elliptic (EE) and mixed (HE). In all cases, we have found that the OTOCs and the WSE have essentially the same behavior, providing with a complete characterization in generic bi-partite systems and at the same time revealing them as very good measures of quantum complexity for phase space distributions. Moreover, we establish a relation between both quantities by means of a recently proven theorem linking the second Renyi entropy and OTOCs.Comment: 6 pages, 5 figure

Quantum and classical complexity in coupled maps

We study a generic and paradigmatic two-degrees-of-freedom system consisting of two coupled perturbed cat maps with different types of dynamics. The Wigner separability entropy (WSE)—equivalent to the operator space entanglement entropy—and the classical separability entropy (CSE) are used as measures of complexity. For the case where both degrees of freedom are hyperbolic, the maps are classically ergodic and the WSE and the CSE behave similarly, growing to higher values than in the doubly elliptic case. However, when one map is elliptic and the other hyperbolic, the WSE reaches the same asymptotic value than that of the doubly hyperbolic case but at a much slower rate. The CSE only follows the WSE for a few map steps, revealing that classical dynamical features are not enough to explain complexity growth.Fil: Bergamasco, Pablo D.. Universidad de Buenos Aires.

A Modified Depolarization Approach for Efficient Quantum Machine Learning

Quantum Computing in the Noisy Intermediate-Scale Quantum (NISQ) era has shown promising applications in machine learning, optimization, and cryptography. Despite the progress, challenges persist due to system noise, errors, and decoherence that complicate the simulation of quantum systems. The depolarization channel is a standard tool for simulating a quantum system's noise. However, modeling such noise for practical applications is computationally expensive when we have limited hardware resources, as is the case in the NISQ era. We propose a modified representation for a single-qubit depolarization channel with two Kraus operators based only on X and Z Pauli matrices. Our approach reduces the computational complexity from six to four matrix multiplications per execution of a channel. Experiments on a Quantum Machine Learning (QML) model on the Iris dataset across various circuit depths and depolarization rates validate that our approach maintains the model's accuracy while improving efficiency. This simplified noise model enables more scalable simulations of quantum circuits under depolarization, advancing capabilities in the NISQ era

Ethnography inquiry and teacher education. The use of diaries for the comprehension of educational practice

We present in this communication a work of inquiry carried our using the diaries of students participating an educational experience in a primary school. Along a semester, a group of 10 students was workomg with a community learning project. These students were engaged with a teacher training experience which is being developed in the Education College at the University of Málaga. In this experience some teacher students attended two subjects of his education as collaborators in this school. His experience was collected systematically in field diaries in which they reflected their everyday experience in the school, as well as his insights, assessments, feelings, etc. These diaries become into the working material to study the school functioning and their experience. For that reason, working meetings were held with teachers of their subjects at the university. Collaboratively, diaries were analyzed, categorized and interpreted in an attempt to understand the school practice, and thus, progress their training process.Universidad de Málaga.
