Abstract. In past decades theoretical studies have been carried out with the double aim of improving knowledge of the main characteristics of the rogue wave and of attempting to predict its sudden appearance. We have tried to generate rogue waves in a water wave tank, using a symmetric spectrum (Akhmediev et al., 2011a) as input on the wave maker. The next step has been to apply a theoretical model to the amplitude envelope of these waves. After some considerations we agreed the best model to be an analog of the Ginzburg–Landau equation.

Abstract. This paper deals with the possible involvement of freak, rogue or giant waves in the damage suffered by the Tanker Prestige, which eventually led to its sinking. By reason of their very characteristics, giant waves are hard to record. Their more or less sudden appearance makes them fairly elusive objects, except for the consequences they produce. However, some hints with regard to the probability of their occurrence can be derived from considering how close the maritime weather of the area of interest is to the situation which is optimal for their generation. This paper takes into account the wave field in the area and at the time of the Prestige accident and investigates how near or how far the wave field was to the instability conditions that are favourable to the generation of freak waves in the different approximations. This paper explores mostly the modulation instability which is one of the most common mechanisms to produce freak waves: it leads to the decomposition of an initially homogeneous train of Stokes waves firstly into a series of groups of waves, whose envelope then produces the so-called "solitons", that then collapse in the form of a giant wave. This mechanism mainly occurs in deep waters. Zakharov studied it in 1968 and, independently, Benjamin and Feir analysed it in 1967. This paper proves that the wave field was conspicuously two dimensional with two main wave components travelling in directions almost orthogonal to each other. This means that the wave field was well outside the instability domain. Therefore it is concluded that freak waves were very unlikely generated and it is improbable that they were responsible for the accident.

Today's academy is a dystopia. Many scholars of color and international scholars face the daunting challenge of navigating neoliberal state institutions that are often built on legacies of racism, colonialism, and classism. This essay brings attention to the feelings of despair, anxiety, and paranoia felt by many scholars of color in the fields of humanities and social sciences, but whose narratives too often become ones of abrupt exit from the Ministry of Knowledge (and) Entrepreneurship (MKE). The essay relies on a discussion of Anzaldúa's intimate terrorism, the composition of today's academy, and the sense of never-quite-being. These themes emerge out of a dialogue with Anzaldúa, Deleuze, and Harney and Moten, who each have something to say about navigating institutions of power from a position of in-betweenness. Then, I assemble themes from contemporary popular dystopia films to develop a performative fiction—a narrative of never-quite-being that embodies the critical theory and dystopic themes woven through the experiences of a border-body in the academy. The essay ends with a discussion of what being intimate looks like for someone that never-quite-is, informed by Anzaldúa's concept of mestizaje and Deleuze's nomad thought.

Today, much of the world has witnessed fundamental transformations, both in the relations between states and their national societies, and in the patterns of economic and political organization at the international level. So the phenomenon of globalization has been strengthened by the interdependence between countries, due to the elimination of trade barriers facilitated by multilateral organizations, the emergence of multinationals and the political will of nations around the world who see the opportunity to improve their economic growth, taking advantage of information technologies and modes of transport. That is why the globalization of markets and advances in modern communication, make the inhabitants of the world more sensitive to an infinity of issues taking special importance, the economic ones. ; Hoy por hoy gran parte del mundo ha sido testigo de transformaciones fundamentales, tanto en las relaciones entre los estados y sus sociedades nacionales, como en los patrones de organización económica y política en el plano internacional. De modo que el fenómeno de la globalización ha tomado fuerza por la interdependencia entre países, debido a la eliminación de barreras comerciales facilitado por las organizaciones multilaterales, el surgimiento de las multinacionales y la voluntad política de las naciones de todo el mundo que ven la oportunidad de mejorar su crecimiento económico, aprovechando las tecnologías de información, y modos de transporte. Es por ello, que la globalización de los mercados y los avances en la comunicación moderna, vuelven a los habitantes de todo el mundo más sensibles ante una infinidad de temáticas cobrando especial importancia, las económicas.

Latina/os experience some of the lowest academic outcomes and youth of Mexican-origin are among the most educationally disadvantaged of all Latina/o subgroups. These disparities impact many Latina/o students including our family. In the 1960s and 1970s, the Chicana/o Movement focused on fighting for equality and access to quality education for Chicana/o students. Our parents were among the students who participated in and benefited from this fight. This set their children on the path to educational success. This is the story of how they broke down the educational barriers and set their children up as projectiles that pelted against an inferior educational system and unequal access. Through the lens of critical race theory (CRT) and Latina/o CRT, we use counter storytelling and narratives to demonstrate the parallels between the barriers and facilitators to educational success we experienced and those of Latina/o students. Barriers include socioeconomic hardships and racial discrimination in school. Facilitators include access and opportunities provided through social activism in the Chicana/o Movement, participation in college pipeline programs, mentorship and authentic caring, culturally relevant curriculum, and familism. We provide recommendations for serving and supporting Latina/o students through the educational pipeline.

El objetivo de este artículo es aproximarse a la experiencia de los niños de clase media en el espacio público del Distrito Federal entre 1928 y 1940, a partir de una muestra de ocho entrevistas de historia oral. A través de esta metodología, y haciendo uso de fuentes hemerográficas, se analizan las dinámicas de movilidad y las diversiones de los niños. La investigación muestra el conocimiento que la mayor parte de los entrevistados tenía de su barrio y da cuenta de los lugares que ellos mismos construyeron, evadiendo así los discursos de miedo que se generaban en los medios de comunicación y que buscaban moldear el movimiento infantil. La principal aportación de este trabajo es que permite analizar las vivencias de los menores de clase media más allá de las escuelas, centros de reclusión o el hogar, cubriendo así, un ámbito poco estudiado en la historia de la infancia.
