Contract Grading in a Technical Writing Classroom: A Case Study

The subjectivity of assessing writing has long been an issue for instructors, who carefully craft rubrics and other indicators of assessment while students grapple with understanding what constitutes an A and how to meet instructor-generated criteria. Based on student frustration with traditional grading practices, this case study of a 20-student technical writing classroom employed teacher-as-researcher observation and student surveys to examine how students in a technical writing classroom in the Northeast collaborated together to generate criteria relating to the quality of their writing assignments. The study indicates that although students perceive more involvement in the grading process, they resist participation in crafting criteria as a class and prefer traditional grading methods by an “expert,” considering it a normative part of the grading process. The study concludes with implications for integrating contract grading in the technical writing classroom

La dimensión jurídica de los elementos de la estatalidad a la luz del caso del autodenominado " Estado Islámico"

The present paper's objective is to inquire into the existence of a legal dimension to the elements of statehood that requires that the components of the State have been obtained by a licit cause -understood as a cause in accordance to International Law's peremptory order-. To these ends, it will be analyzed in concrete whether the organization known as the "Islamic State of Iraq and the Levant" can be considered a State under the current norms of International Law.Fil: Guisado Litterio, Tomás M. Universidad de Buenos Aires. Facultad de Derecho. Buenos Aires, ArgentinaEl presente trabajo tiene por objeto indagar sobre la existencia de una dimensión jurídica de los elementos de la estatalidad que requiera que los componentes del Estado hayan sido obtenidos por causa lícita, entendiéndose como tal a una no contraria al ordenamiento imperativo del Derecho Internacional. A tales efectos, se analizará en concreto si la agrupación autodenominada "Estado Islámico de Irak y el Levante" puede ser considerada un Estado conforme a las normas actuales de Derecho Internacional.\

De los lexicones: NLP en la construcción del Lexicón de Drivers de Mercado en Español

In our approach when analyzing and interpreting financial news, we state that apart from the need of a tailored-made lexicon it is critical to design market drivers lexicons, defining a “driver” as the factor or force that has a material impact on a specific activity on another entity, which is contextually dependent and which affects the financial market at a specific time. Therefore, our proposal contemplates three key aspects: first, the conceptualization of the market driver typology, second, a brief explanation of Natural Language Processing (NLP) techniques applied in the construction of market drivers lexicons to finally explain the relevance of the market drivers lexicons in the interpretation of financial news and its correlation to the market movements.En nuestra aproximación sobre el análisis e interpretación de las noticias financieras sostenemos que, además de la necesidad de un lexicón de propósitos específicos para finanzas, es fundamental contar con lexicones de “drivers de mercado”, siendo un driver de mercado, aquel factor que ejerce un efecto material sobre una actividad de otra entidad, contextualmente dependiente y que afecta al mercado financiero en un momento determinado. Desde nuestro enfoque, proponemos: en primer lugar, conceptualizar las diferentes categorías de “drivers de mercado”, en segundo lugar, explicar de manera sucinta cómo mediante las técnicas de Procesamiento de Lenguaje Natural (NLP) se realiza la construcción del lexicón de drivers, y explicitar la relevancia del lexicón de drivers en la interpretación de noticias financieras y su correlación con los movimientos del mercado

Debonding of adhesive joints by means of microwave and induction heating processes

In this work, an innovative technique for adhesive joint separation that combines the use of a hybrid-modified adhesive with microwave (MW) or induction heating (IH) [1-3] processes is presented. Graphene nanoplatelets (GnPs) and iron oxide particles were used to modify a thermoplastic adhesive, polyolefin hot-melt adhesive by mean of a twin-screw extruder. This thermoplastic adhesive, already used for bonding automotive applications, was modified with both iron oxide and GnPs in order to enhance the electrical properties and the sensitivity to MW and IH. The mechanical and electrical properties together with the sensitivity of the modified adhesives to microwave or induction heating processes are investigated. Single Lap Joint (SLJ) specimens were used to evaluate the mechanical properties of the pristine and the modified adhesive. The mechanical tests illustrate that the maximum loads of modified adhesives decrease slightly. Tests conducted with microwave and induction heating processes showed that these two systems are able to melt the modified adhesive. Thus, the separation of bonded joints is possible with both systems. The temperature increase of the induction heating system is found to be more rapid than the microwaves but the latter system is energetically more efficient. Scanning Electron Microscope (SEM) was used to measure the particle distribution and to evaluate the differences between the manual mixed mode and the tween extruder system as preliminary analysis
