DCMF: DC & Microformats, a good marriage

This report introduces the Dublin Core Microformats (DCMF) project, a new way to use the DC element set within X/HTML. The DC microformats encode explicit semantic expressions in an X/HTML webpage, by using a specific list of terms for values of the attributes “rev” and “rel” for and elements, and “class” and “id” of other elements. Microformats can be easily processed by user agents and software, enabling a high level of interoperability. These characteristics are crucial for the growing number of social applications allowing users to participate in the Web 2.0 environment as information creators and consumers. This report reviews the origins of microformats; illustrates the coding of DC microformats using the Dublin Core Metadata Gen tool, and a Firefox extension for extraction and visualization; and discusses the benefits of creating Web services utilizing DC microformats

Vis LED Photo-Fenton Degradation of 124-Trichlorobenzene at a Neutral pH Using Ferrioxalate as Catalyst

Chlorinated organic compounds (COCs) are among the more toxic organic compounds frequently found in soil and groundwater. Among these, toxic and low-degradable chlorobenzenes are commonly found in the environment. In this work, an innovative process using hydrogen peroxide as the oxidant, ferrioxalate as the catalyst and a visible light-emitting diode lamp (Vis LED) were applied to successfully oxidize 124-trichlorobenzene (124-TCB) in a saturated aqueous solution of 124-TCB (28 mg L−1) at a neutral pH. The influence of a hydrogen peroxide (HP) concentration (61.5–612 mg L−1), Fe3+ (Fe) dosage (3–10 mg L−1), and irradiation level (Rad) (I = 0.12 W cm−2 and I = 0.18 W cm−2) on 124-TCB conversion and dechlorination was studied. A D–Optimal experimental design combined with response surface methodology (RSM) was implemented to maximize the quality of the information obtained. The ANOVA test was used to assess the significance of the model and its coefficients. The maximum pollutant conversion at 180 min (98.50%98.50%) was obtained with Fe = 7 mg L−1, HP = 305 mg L−1, and I = 0.12 W cm−2. The effect of two inorganic anions usually presents in real groundwater (bicarbonate and chloride, 600 mg L−1 each) was investigated under those optimized operating conditions. A slight reduction in the 124-TCB conversion after 180 min of reaction was noticed in the presence of bicarbonate (8.31%) and chloride (7.85%). Toxicity was studied with Microtox® (Azur Environmental, Carlsbad, CA, USA) bioassay, and a remarkable toxicity decrease was found in the treated samples, with the inhibition proportional to the remaining 124-TCB concentration. That means that nontoxic byproducts are produced in agreement with the high dechlorination degrees noticed.Depto. de Ingeniería Química y de MaterialesFac. de Ciencias QuímicasTRUEUnión EuropeaComunidad de MadridMinisterio de Ciencia, Innovaciónpu

Invarianza factorial de la TEOSQ en jóvenes deportistas mexicanos y españoles

ESPAÑOL: Dentro de la teoría de las metas de logro (Nicholls, 1989), Duda y Nicholls (ver Duda, 1989; Duda & Whitehead, 1998) desarrollaron el cuestionario de Orientación al Ego y a la tarea en el deporte (teosq) para evaluar las diferencias individuales en las orientaciones de metas de logro. Este estudio ofrece apoyo a la validez factorial y fiabilidad del teosq en jóvenes deportistas españoles (n = 563) y mexicanos (n = 553). Los resultados muestran que la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes en las dos poblaciones. Sin embargo, existen diferencias entre las medias latentes en la orientación al ego, siendo la media más alta en la población mexicana. Por último, los resultados muestran una alta consistencia interna del cuestionario en las versiones española y mexicana. ENGLISH: Within the Achievement Goal Theory (Nicholls, 1989), Duda and Nicholls (see Duda, 1989; Duda & Whitehead, 1998), the Task and Ego Orientation in Sport Questionnaire (teosq) assesses individual differences in achievement goal orientations. This study examines factorial validity and reliability of teosq in the case of Spanish (n = 563) and Mexican (n = 553) junior athletes. The factor structure, factor loadings and intercepts of the instrument can be considered invariant across groups. However, the latent means observed for the ego orientation subscale differ, the highest emerging from the Mexican population. Finally, results show high internal consistency of both Spanish and Mexican versions of teosq

La autoeficacia física percibida y el rendimiento deportivo en taekwondo

En el contexto físico-­‐deportivo una de las variables de mayor interés tanto para entrenadores, deportistas como para el público en general es el rendimiento deportivo. Actualmente se tiende a identificar características o habilidades psicológicas que pueden estar interviniendo en dicho rendimiento. Una de las variables psicológicas más estudiadas, en los últimos años, en relación con el rendimiento deportivo es la auto-­‐confianza en las propias capacidades físicas
