Critical Behaviour of the Two Dimensional Step Model
We use finite--size scaling of Lee--Yang partition function zeroes to study
the critical behaviour of the two dimensional step or sgn model. We
present evidence that, like the closely related --model, this has a phase
transition from a disordered high temperature phase to a low temperature
massless phase where the model remains critical. The critical parameters
(including logarithmic corrections) are compatible with those of the
--model indicating that both models belong to the same universality class.Comment: 6 pages latex, 3 postscript figures, compressed and uuencoded

Ecojusticia, equidad y ética: retos para la orientación educativa y profesional
In social and environmental terms we live in precarious and uncertain times, where not only the sustainability of the
planet rests in the balance, but also that of human existence. Many nation-states around the world talk of the
importance of social cohesion, and are aware of the threat of environmental degradation, climate change, and
ecological well-being. However, the dominating global policy discourse, particularly championed in the West, is
located within a delimiting neo/liberal political framework. With a few noticeable exceptions, the influence of
neo/liberal thinking continues to flourish in the contemporary career literature where there has been little deep
critical engagement with the discourse of capitalist economics and how these impact human and environmental
well-being. Often caught up in market-led discourses, and captured by the notion that ‘work sets you free’,
educational and career guidance has been located within an uncritical economic frame. Its energies tend to be
directed towards the preparation of individuals to make ‘good’ educational and occupational choices, underpinned
by the need for ‘clients’ to acquire the skills and competencies demanded by employers (and the economy)
(Bengtsson, 2011; Irving, 2018). The disjuncture between educational and career guidance and social and
environmental justice (i.e. ecojustice) has rarely been breached. In this article, we seek to disrupt dominant
discourses of the market that currently permeates thinking in education by identifying how an ecojustice
perspective provides a forward looking and equitable foundation for educational and career guidance.En términos sociales y ambientales, vivimos en tiempos precarios e inciertos, donde no solo la sostenibilidad del
planeta está en juego, sino también la de la existencia humana. Muchos estados-nación de todo el mundo hablan de
la importancia de la cohesión social y son conscientes de la degradación ambiental, el cambio climático y la amenaza
al bienestar ecológico y social. Sin embargo, el discurso dominante de la polÃtica global, particularmente defendido
en Occidente, se sitúa dentro de un marco polÃtico neoliberal. Con algunas notables excepciones, la influencia del
pensamiento neoliberal continúa siendo hegemónico en el campo de la educación y de la orientación profesional,
donde en términos generales ha habido poco compromiso crÃtico profundo con el discurso de la economÃa capitalista
y cómo este impacta sobre el bienestar humano y ambiental. A menudo atrapada en discursos dirigidos por el mercado
y por la noción de que "el trabajo nos hace libres", la orientación educativa y profesional se ha ubicado dentro de un
marco económico acrÃtico. Se tiende a preparar a los individuos para tomar "buenas" decisiones educativas y
ocupacionales, respaldadas por la necesidad de que adquieran las habilidades y competencias exigidas por los
empleadores (y la economÃa) (Bengtsson, 2011; Irving, 2018). La disyuntiva entre la orientación educativa y
profesional y la justicia social y ambiental (la ecojusticia) rara vez se ha abordado. En este artÃculo cuestionamos los
discursos dominantes del mercado que actualmente impregnan el pensamiento en educación, y proponemos la
adopción de una perspectiva de ecojusticia que proporciona una guÃa para el futuro y contribuye a promover la
equidad desde la orientación educativa y profesional
