La estructuración del espacio urbano y productivo de Gadir durante la fase urbana clásica: Cambios y perduraciones

La reafirmación del modelo político-administrativo ciudadano tras la fase arcaica colonial abre una nueva etapa de prosperidad en la antigua fundación tiria. El esplendor de Gadir en el s. V a.C. se refleja en los textos clásicos y en los hallazgos arqueológicos y, sin embargo, nuestros conocimientos sobre el desarrollo histórico de la ciudad de época púnica son muy limitados. El horizonte arcaico comienza a esclarecerse tras los hallazgos del Teatro Cómico que han sacado a la luz los restos de la fundación tiria y, sin embargo, la ciudad posterior continúa siendo una gran incógnita. ¿A qué lugar se traslada la población una vez que se abandona el asentamiento primitivo? ¿Quiénes son los individuos enterrados en los excepcionales sarcófagos antropoides? ¿Qué relación jerárquica existe entre el asentamiento insular y los situados en tierra firme? ¿Qué papel jugó la industria y comercialización de las salazones? Los interrogantes planteados son múltiples y no hacen más que evidenciar la incapacidad del paradigma tradicional para explicar el desarrollo histórico de la Gadir postcolonial y la necesidad de buscar nuevos modelos interpretativos.

La enseñanza de las construcciones pasivas e impersonales con "se" en español como L2. ¿Cuántas distinciones son necesarias?

Este artículo sugiere un enfoque nuevo a la enseñanza de las dos estructuras gramaticales la pasiva refleja y el “se” impersonal para las clases universitarias de E/LE. Concretamente, se argumenta que las dos se deberían tratar como construcciones pasivas, basada en un análisis léxico-funcional de ellas que enfoca la lingüística contrastiva. Incluso para la instrucción de E/LE, se recomienda una aproximación contrastiva en la que se enfocan tanto la reflexión metalingüística como la competencia del estudiante en el L2. Específicamente, el uso de córpora lingüísticos en la clase forma una parte integral de la instrucción. El uso de un corpus estimula la curiosidad del estudiante, le expone a material de lengua auténtica, y promulga la reflexión inductiva independiente.

¿Fue la crisis política del Occidente musulmán del siglo XIII debida a un cambio climático? Una aproximación histórica al fin del Periodo Cálido Medieval

Durante el siglo XIII se produjo una sucesión de revueltas que supuso la desaparición del Imperio almohade y su sustitución por poderes regionales en al-Andalus, el Magreb y el Magreb al-Aqsà. La historiografía ha presentado el surgimiento y pugna entre estos poderes como un fenómeno social, político e, incluso, cultural y religioso, con el que se ha podido explicar su aniquilación o marginalización. Este trabajo pretende contextualizar los hechos desde una perspectiva medioambiental, de forma que la desintegración del califato almohade, el surgimiento de aquellos poderes y la progresión de los reinos cristianos en la península ibérica puedan entenderse desde una visión global de cambio climático y una posible crisis agrícola.

Relaciones de poder y memoria de un linaje. La intervención de la Casa de Moscoso en la Compostela de los siglos XIV-XVI

La ciudad ofrecía en la Baja Edad Media claras oportunidades para aquellos nobles que supieran situarse en el complejo juego de la política urbana y sus diversas instancias de poder. Para ello siempre se hace necesario contar con los apoyos sociales y físicos adecuados. La dinámica de enfrentamientos entre el Arzobispo de Santiago y el concello compostelano presenta un ejemplo inmejorable para valorar en su justa medida la inserción de la nobleza territorial en las relaciones de poder. Para abordar este caso se analizará la participación en la vida pública –también las revueltas urbanas– de la Casa de Moscoso tanto a través de su larga trayectoria de enfrentamientos con la Iglesia como mediante el estudio de su patrimonio urbano, incluyendo aquellos elementos relacionados con la creación de una memoria específica del linaje dentro de la ciudad.

Entre reglas y excepciones. Es decir, como legitimar las decisiones colectivas

El ensayo examina la cuestión de la aplicación de las reglas y de la capacidad real para tratar casos específicos, llegando a la conclusión de que es la excepción la que confirma la regla, a condición de que sea dialógicamente construida, para que sea interpretable y aplicable por parte de sus numerosos destinatarios en las políticas públicas más complejas y conflictuales, sobre todo a nivel local.

Public internet access revisited

In recent years the Australian government has dedicated considerable project funds to establish public Internet access points in rural and regional communities. Drawing on data from a major Australian study of the social and economic impact of new technologies on rural areas, this paper explores some of the difficulties rural communities have faced in setting up public access points and sustaining them beyond their project funding. Of particular concern is the way that economic sustainability has been positioned as a measure of the success of such ventures. Government funding has been allocated on the basis of these rural public access points becoming economically self-sustaining. This is problematic on a number of counts. It is therefore argued that these public access points should be reconceptualised as essential community infrastructure like schools and libraries, rather than potential economic enterprises.

Towards integrated assessments for urban development

The role of sustainability in urban design is becoming increasingly important as Australia’s cities continue to grow, putting pressure on existing infrastructure such as water, energy and transport. To optimise an urban design many different aspects such as water, energy, transport, costs need to be taken into account integrally. Integrated software applications assessing urban designs on a large variety of aspects are hardly available. With the upcoming next generation of the Internet often referred to as the Semantic Web, data can become more machine-interpretable by developing ontologies that can support the development of integrated software systems. Software systems can use these ontologies to perform an intelligent task such as assessing an urban design on a particular aspect. When ontologies of different applications are aligned, they can share information resulting in interoperability. Inference such as compliancy checks and classifications can support aligning the ontologies. A proof of concept implementation has been made to demonstrate and validate the usefulness of machine interpretable ontologies for urban designs.

From literacy to multiliteracies : diverse learners and pedagogical practice

In this paper, we provide specific examples of the educational promises and problems that arise as multiliteracies pedagogical initiatives encounter conventional institutional beliefs and practices in mainstream schooling. This paper documents and characterizes the ways in which two specific digital learning initiatives were played out in two distinctive traditional schooling contexts, as experienced by two different student groups: one comprising an elite mainstream and the other an excluded minority. By learning from the instructive complications that arose out of attempts by innovative and well-meaning educators to provide students with more relevant learning experiences than currently exist in mainstream schooling, this paper contributes fresh perspectives and more nuanced understandings of how diverse learners and their teachers negotiate the opportunities and challenges of the New London Group's vision of a multiliteracies approach to literacy and learning. We conclude by arguing that, where multiliteracies are understood as “garnish” to the “pedagogical roast” of traditional code-based and print-based academic literacies, they will continue to work on the sidelines of mainstream schooling and be seen only as either useful extensions or helpful interventions for high-performing and at-risk students respectively.

Controlled rate thermal analysis of sepiolite

CRTA technology offers better resolution and a more detailed interpretation of the decomposition processes of a clay mineral such as sepiolite via approaching equilibrium conditions of decomposition through the elimination of the slow transfer of heat to the sample as a controlling parameter on the process of decomposition. Constant-rate decomposition processes of non-isothermal nature reveal changes in the sepiolite as the sepiolite is converted to an anhydride. In the dynamic experiment two dehydration steps are observed over the ~20-170 and 170-350°C temperature range. In the dynamic experiment three dehydroxylation steps are observed over the temperature ranges 201-337, 337-638 and 638-982°C. The CRTA technology enables the separation of the thermal decomposition steps.

Exercise and secondary lymphedema : safety, potential benefits, and research issues

Participating in regular physical activity is encouraged following breast cancer (BC) treatment, except for those who have subsequently developed lymphoedema. We designed a randomised controlled trial to investigate the effect of participating in a supervised, mixed-type, moderate-intensity exercise program among women with lymphoedema following breast cancer. Women <76 years who had completed BC treatment at least six months prior and subsequently developed unilateral, upper-limb lymphoedema were randomly allocated to an intervention (n=16) or control (n=16) group. The intervention group (IG) participated in 20 supervised group exercise sessions over 12 weeks, while the control group (CG) was instructed to continue habitual activities. Lymphoedema status was assessed by bioimpedance spectroscopy (impedance ratio between limbs) and perometry (volume difference between limbs). Mean baseline measures were similar for the IG (1.13+0.15 and 337+307ml, respectively) and CG (1.13+0.15 and 377+416ml, respectively) and no changes were observed over time. However, 2 women in the IG no longer had evidence of lymphoedema by study end. Average attendance was over 70% of supervised sessions, and there were no withdrawals. The results indicate that, at worst, exercise does not exacerbate secondary lymphoedema. Women with secondary lymphoedema should be encouraged to be physically active, optimising their physical and psychosocial recovery.

Effects of inoculating dose on the kinetics of Chlamydia muridarum genital infection in female mice

Chlamydia trachomatis infections have been implicated in problems such as pelvic inflammatory disease and infertility in females. Although there are some studies examining the kinetics of ascending infection, there is limited information on the kinetics of pathology development and cellular infiltrate into the reproductive tissues in relation to the effects of inoculating dose, and a better understanding of these is needed. The murine model of female genital tract Chlamydia muridarum infection is frequently used as a model of human C. trachomatis reproductive tract infection. To investigate the kinetics of ascending genital infection and associated pathology development, female BALB/c mice were intravaginally infected with C. muridarum at doses ranging from 5102 to 2.6106 inclusion forming units. We found that the inoculating dose affects the course of infection and the ascension of bacteria, with the highest dose ascending rapidly to the oviducts. By comparison, the lowest dose resulted in the greatest bacterial load in the lower reproductive tract. Interestingly, we found that the dose did not significantly affect inflammatory cell infiltrate in the various regions. Overall, this data show the effects of infectious dose on the kinetics of ascending chlamydial infection and associated inflammatory infiltration in BALB/c mice.

Serious playground : using Second Life to engage high school students in urban planning

Virtual world platforms such as Second Life have been successfully used in educational contexts to motivate and engage learners. This article reports on an exploratory workshop involving a group of high school students using Second Life for an urban planning project. Young people are traditionally an under-represented demographic when it comes to participating in urban planning and decision making processes. The research team developed activities that combined technology with a constructivist approach to learning. Real world experiences and purposes ensured that the workshop enabled students to see the relevance of their learning. Our design also ensured that play remained an important part of the learning. By conceiving of the workshop as a ‘serious playground’ we investigated the ludic potential of learning in a virtual world.
