Children’s socialization, involved parenting, and the construction of the family-school partnership in everyday family interactions: a study on parent-assisted homework as a morally dense educational arena

This study investigates an activity that takes place at the intersection between family and school and plays a key role in the building of the family-school partnership largely promoted by education policies: parent-assisted homework. Even though this topic is not new in pedagogical research, what is innovative about this study is the focus on naturally occurring parent-child conversations during homework. Adopting a phenomenological approach to the study of educational events and relying on conversation analysis, the present study analyzes 62 video-recorded sessions of parent-assisted homework collected in 19 Italian families with children aged 6-10 years old (i.e., attending primary school). The analysis of parent-child interactions reveals that parent-assisted homework is not only a site for formal learning but also and primarily a morally dense educational arena. Through the ‘small talks’ that accompany the completion of homework exercises, parents and children evoke and co-construct moral ideologies concerning topics as diverse as learning, school rules and standards, ‘good, involved parenting’, the family-school partnership, children’s autonomy, virtue, time management, and the organization of knowledge and authority in interaction. By taking part in everyday homework interactions, children are educated to culture-specific ethical systems and socialized into morally competent members of their communities, while parents implement the family-school partnership and comply with the model of “involved parent” proposed by pedagogical research and policies. Providing empirical evidence for the moral and educational relevance of ordinary family talk, this study contributes to pedagogical research on family life and promotes parents’ reflexivity about their mundane interactive activities.

Emotions in legal decisions: the construction of objective narratives in Italian criminal trials

Drawing on ethnographic data collected in Italian courts and prosecution offices, this dissertation offers new perspectives on legal decision-making by highlighting the importance of emotions for constructing and evaluating legal narratives. Focusing on criminal cases, it describes and dissects how judges and prosecutors use emotions in reflection and action tied to lay narratives and legal constraints. The analysis shows that legal professionals engage in different types of emotional dynamics when dealing with stories; first, they develop gut feelings, which are either endorsed or kept at distance by means of emotional reflexivity, to comply with legal ideals of objectivity and impartiality. Second, empathy emerges as a crucial tool to direct the interaction with lay people and to interpret legal prerequisites, such as credibility, and intent. Finally, the dissertation shows that lay stories lead legal professionals to become passionate and committed towards the correct application of the law, the restoration of the moral order, and the achievement of justice. In light of the empirical findings, this thesis strives to develop a theoretical understanding of legal decision-making as narrative work that includes emotional dynamics consistent with rational, objective action.

On and off air: an ethnographic exploration of minority radio in Portugal

Taking a Media Anthropology’s approach to dynamics of mediated selfrepresentation in migratory contexts, this thesis starts by mapping radio initiatives produced by, for and/or with migrants in Portugal. To further explore dynamics of support of initial settlement in the country, community-making, cultural reproduction, and transnational connectivity - found both in the mapping stage and the minority media literature (e.g. Kosnick, 2007; Rigoni & Saitta, 2012; Silverstone & Georgiou, 2005) - a case study was selected: the station awarded with the first bilingual license in Portugal. The station in question caters largely to the British population presenting themselves as “expats” and residing in the Algarve. The ethnographic strategy to research it consisted of “following the radio” (Marcus, 1995) beyond the station and into the events and establishments it announces on air, so as to relate production and consumption realms. The leading research question asks how does locally produced radio play into “expats” processes of management of cultural identity – and what are the specificities of its role? Drawing on conceptualizations of lifestyle migration (Benson & O’Reilly, 2009), production of locality (Appadurai 1996) and the public sphere (Butsch, 2007; Calhoun & et al, 1992; Dahlgren, 2006), this thesis contributes to valuing radio as a productive gateway to research migrants’ construction of belonging, to inscribe a counterpoint in the field of minority media, and to debate conceptualizations of migratory categories and flows. Specifically, this thesis argues that the station fulfills similar roles to other minority radio initiatives but in ways that are specific to the population being catered to. Namely, unlike other minority stations, radio facilitates the process of transitioning between categories along on a continuum linking tourists and migrants. It also reflects and participates in strategies of reterritorialization that rest on functional and partial modes of incorporation. While contributing to sustain a translocality (Appadurai, 1996) it indexes and fosters a stance of connection that is symbolically and materially connected to the UK and other “neighborhoods” but is, simultaneously, oriented to engaging with the Algarve as “home”. Yet, besides reifying a British cultural identity, radio’s oral, repetitive and ephemeral discourse particularly trivializes the reproduction of an ambivalent stance of connection with place that is shared by other “expats”. This dynamic is related to migratory projects driven by social imaginaries fostered by international media that stimulate the search for idealized ways of living, which the radio associates with the Algarve. While recurrently localizing and validating the narrative projecting an idealized “good life”, radio amplifies dynamics among migrants that seem to reaffirm the migratory move as a good choice.

Continuous monitoring of concrete mechanical properties since an early age to support construction phasing

The assessment of concrete mechanical properties during construction of concrete structures is of paramount importance for many intrinsic operations. However many of the available non-destructive methods for mechanical properties have limitations for use in construction sites. One of such methodologies is EMM-ARM, which is a variant of classic resonant frequency methods. This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, as to provide real-time information about concrete mechanical properties such as E-modulus and compressive strength. To achieve the aforementioned objective, a set of adaptations to the method have been successfully implemented and tested: (i) the reduction of the beam span; (ii) the use of a different mould material and (iii) a new support system for the beams. Based on these adaptations, a reusable mould was designed to enable easier systematic use of EMMARM. A pilot test was successfully performed under in-situ conditions during a bridge construction.

Late-medieval construction site management at the Monastery of Jerónimos in Lisbon

Through the analysis of the exceptional accounting documents of 1517 related to the construction of the Monastery of Jerónimos (Lisbon), this paper discusses the main characteristics of a new model of construction site organization. In the later Middle Ages we can find, among others, two main models of constructing site organization. One, older and more widespread, consisted in a centralized and pyramidal management model. The other, apparently more recent, was based in the existence of several autonomous teams working simultaneously, each one responsible for building a specific part or section of the building. This paper describes and discusses this new organizational model as it was adopted and implemented by João de Castilho (1470–1552) for the construction of the Monastery of Jerónimos in 1517, probably for the first time in Portugal, but with some parallels in other places in Europe.

Safety management of cranes on construction sites in Portugal: Critical factors of safety

The evolution of the construction caused a need to use more effective equipments, capable of meeting the increasingly demanding deadlines for the completion of works. In this context, the safety and efficiency of equipment have become key aspects in order to optimize the execution time of the works, as well as reducing labor costs and loss of materials. With the evolution of construction and construction processes, cranes have come to represent a signal of the construction of buildings, revealing to be, in most of the cases, the main equipment of construction sites. Currently, some engineers revels some apprehension regarding the use and handling of cranes which is natural and acceptable, since an equipment failure can lead to serious or fatal accidents. The factors affecting safety management of the cranes in construction sites were investigated, identified, classified and evaluated according to their degree of importance, through interviews with representatives of the general contractors of a set of selected construction sites.

Entre la ejecución y la representación: intersecciones de lo real en la construcción escénica. Between the execution and the representation: intersections of the real thing in the scenic construction.

Esta propuesta de investigación se enmarca en los encuentros y discusiones que se están realizando en la Escuela de Artes de la Facultad de Filosofía y Humanidades (CEPIA, CIFFyH y SeCyT, de la U.N.C), en relación a las problemáticas de la investigación en Artes. Los encuentros llevados a cabo en diversas ocasiones y a lo largo de 2009, demuestran la necesidad de establecer un campo particular de la investigación y su relación con la práctica artística. Este proyecto nace de estas inquietudes y establece ciertos ejes de trabajo que permiten poner en práctica ciertos esbozos imaginados. En este sentido, nuestra propuesta se centra en definir la misma construcción escénica como objeto de estudio, delimitando sobre éste la problemática de lo real en el trabajo de la ficción, proponiendo además un equipo que permita investigar en su propio desarrollo creativo las diversas variables que entran en juego. De este modo, se trabajará en una propuesta de laboratorio escénico donde los planteos de orden teórico atraviesen la práctica y, a su vez, la observación de ésta permita una reelaboración y profundización del pensamiento contemporáneo sobre la problemática ejecución/representación, desde los diversos órdenes en que ésta interviene. La idea de representación teatral que planteaba Aristóteles señala que las acciones devienen necesariamente en la definición del carácter de los personajes. Este concepto es clave en el desarrollo del teatro occidental y por ende en las diferentes concepciones de actor. La definición de acción dada por Aristóteles es problemática para parte del teatro contemporáneo ya que supone que toda acción es mimética. También da por supuesto que en el teatro se conforman personajes, y que la unidad narrativa está dada por una programática, que es definida por la acción.La presente investigación se propone indagar en la relación entre la ejecución de la acción y su representación en el desarrollo de un laboratorio teatral. Esto implica que necesariamente es aplicada al trabajo escénico. Nuestra hipótesis de partida es que la relación conflictiva entre acción, ejecución de la misma y representación, se produce a partir de la operación material sobre lo real . Estas intersecciones podrían ser pensadas como una teoría del montaje donde la corporalidad es el principio necesario e irreductible de la construcción. La intersección de lo real es una problemática que permite ahondar sobre los procedimientos por los cuales se construye la escena. La idea de un teatro material, obliga a pensar con qué procedimientos se construye ficción. Un teatro que intenta recalar en lo “real” como modo de señalar la cosa misma, se propone, desde la perspectiva de la realización, indagar en los mecanismos de su construcción (procedimientos), por lo cual supone que la actividad teatral puede dar cuenta de los procesos por los cuales se realiza. La realización de una acción, puede remitir a sí misma y genera una relación “extraña” y ambigua con el mundo de referencia. La acción en sí misma, pone en cuestión la idea de modelo y da cuenta de una crisis en la representación. La teoría ha intentado dividir y sistematizar de manera binaria la manifestación teatral: Teatro de Representación/ Teatro Performático, para distinguir un teatro vinculado a la creación de personajes o para relacionarlo a un teatro de ejecución. Sin embargo, pensamos que es posible encontrar en la producción escénica, intersecciones de lo real que median el mundo de la representación y el de la performance para la construcción de ficción. Nuestra hipótesis de base es que si intervenimos el plano de la ejecución en el actor, la representación varía sustancialmente sus mecanismos de producción de sentido. Este primer planteo no es conflictivo hasta que se pone de manifiesto lo real. This research’s proposal is framed into the meetings and discussions that have been taking place in the School of Arts of the Faculty of Philosophy and Humanities (CEPIA, CIFFyH y SeCyT, of the National University of Cordoba), concerning the difficulties of research in Arts. The meetings carried out along 2009, demonstrate the need to establish a particular field of research and its relation to the practice of arts. This project is born from these concerns and it establishes central axis for the work, that enables us to put on practice some sketches imagined. In this regard, our proposal focuses on defining the construction of the scene as object of study, in itself, delimiting the issue of “the real” in the work of fiction. Proposing, furthermore, a team for researching the many variables that comes into play, in their own creative development. Consequently, the work will be developed in the method of a scenic laboratory, where the theoretical proposals cross over the practice and, in turn, these observations allow a reworking and deepen of contemporary thinking about the problematic of performance / representation, from the diverse orders in which it intervene. The idea of theatrical performance proposed by Aristotle, indicate that actions necessarily turn into the definition of the nature of the characters. This concept is key to the development of Western theaterand consequently on the different conceptions of actor. The definition of action given by Aristotle is problematic for a part of the contemporary theater, because it assumes that every action is mimetic. Also presumes that in the theatre the characters are formed, and narrative unit is given by a programmatic, which is defined by the action. This research proposes to explore the relationship between implementation of the action and its representation in the development of a theatrical laboratory. This implies that it is applied necessarily to the scenic practice. Our preliminary hypothesis is that the co.

Construction and characterisation of a complete reverse genetics system of dengue virus type 3

Dengue virulence and fitness are important factors that determine disease outcome. However, dengue virus (DENV) molecular biology and pathogenesis are not completely elucidated. New insights on those mechanisms have been facilitated by the development of reverse genetic systems in the past decades. Unfortunately, instability of flavivirus genomes cloned in Escherichia coli has been a major problem in these systems. Here, we describe the development of a complete reverse genetics system, based on the construction of an infectious clone and replicon for a low passage DENV-3 genotype III of a clinical isolate. Both constructs were assembled into a newly designed yeast- E. coli shuttle vector by homologous recombination technique and propagated in yeast to prevent any possible genome instability in E. coli . RNA transcripts derived from the infectious clone are infectious upon transfection into BHK-21 cells even after repeated passages of the plasmid in yeast. Transcript-derived DENV-3 exhibited growth kinetics, focus formation size comparable to original DENV-3 in mosquito C6/36 cell culture. In vitro characterisation of DENV-3 replicon confirmed its identity and ability to replicate transiently in BHK-21 cells. The reverse genetics system reported here is a valuable tool that will facilitate further molecular studies in DENV replication, virus attenuation and pathogenesis.

Design and Construction Procedures for Concrete Overlay and Widening of Existing Pavements, September 2005

State Highway Departments and local street and road agencies are currently faced with aging highway systems and a need to extend the life of some of the pavements. The agency engineer should have the opportunity to explore the use of multiple surface types in the selection of a preferred rehabilitation strategy. This study was designed to look at the portland cement concrete overlay alternative and especially the design of overlays for existing composite (portland cement and asphaltic cement concrete) pavements. Existing design procedures for portland cement concrete overlays deal primarily with an existing asphaltic concrete pavement with an underlying granular base or stabilized base. This study reviewed those design methods and moved to the development of a design for overlays of composite pavements. It deals directly with existing portland cement concrete pavements that have been overlaid with successive asphaltic concrete overlays and are in need of another overlay due to poor performance of the existing surface. The results of this study provide the engineer with a way to use existing deflection technology coupled with materials testing and a combination of existing overlay design methods to determine the design thickness of the portland cement concrete overlay. The design methodology provides guidance for the engineer, from the evaluation of the existing pavement condition through the construction of the overlay. It also provides a structural analysis of various joint and widening patterns on the performance of such designs. This work provides the engineer with a portland cement concrete overlay solution to composite pavements or conventional asphaltic concrete pavements that are in need of surface rehabilitation.

Assessing the vulnerability of women to sexually transmitted diseases STDS/ HIV: construction and validation of markers

Objective To construct and validate markers of vulnerability of women to STDs/HIV, taking into consideration the importance of STDs/HIV. Method Methodological study carried out in three stages: 1) systematic review and identification of elements of vulnerability in the scientific production; 2) selection of elements of vulnerability, and development of markers; 3) establishment of the expert group and validation of the markers (content validity). Results Five markers were validated: no openness in the relationship to discuss aspects related to prevention of STDs/HIV; no perception of vulnerability to STDs/HIV; disregard of vulnerability to STDs/ HIV; not recognizing herself as the subject of sexual and reproductive rights; actions of health professionals that limit women’s access to prevention of STDs/HIV. Each marker contains three to eleven components. Conclusion The construction of such markers constituted an instrument, presented in another publication, which can contribute to support the identification of vulnerabilities of women in relation to STDs/HIV in the context of primary health care services. The markers constitute an important tool for the operationalization of the concept of vulnerability in primary health care and to promote inter/multidisciplinary and inter/multi-sectoral work processes.

METHOD Methodological research, carried out in three steps: construction of dimensions and items, face and content validity and semantic analysis of the items. RESULTS The face and content validity was carried out by 10 judges working in healthcare, teaching and research. Items with Content Validity Index (CVI) ≥ 0.9 were kept in full or undergone revisions as suggested by the judges. Semantic analysis, performed twice, indicated that there was no difficulty in understanding the items. CONCLUSION The instrument with three dimensions (organization of healthcare network to pregnancy and childbirth, evidence-based practices and work processes) followed the steps recommended in the literature, concluded with 50 items and total CVI of 0.98.

Evaluation of the Buena Vista IBRD Bridge: A Furthering of Accelerated Bridge Construction in Iowa, February 2012

The need to construct bridges that last longer, are less expensive, and take less time to build has increased. The importance of accelerated bridge construction (ABC) technologies has been realized by the Federal Highway Administration (FHWA) and the Iowa Department of Transportation (DOT) Office of Bridges and Structures. This project is another in a series of ABC bridge projects undertaken by the Iowa DOT. Buena Vista County, Iowa, with the assistance of the Iowa Department of Transportation (DOT) and the Bridge Engineering Center (BEC) at Iowa State University, constructed a two-lane single-span precast box girder bridge, using rapid construction techniques. The design involved the use of precast, pretensioned components for the bridge superstructure, substructure, and backwalls. This application and demonstration represents an important step in the development and advancement of these techniques in Iowa as well as nationwide. Prior funding for the design and construction of this bridge (including materials) was obtained through the FHWA Innovative Bridge Research and Deployment (IBRD) Program. The Iowa Highway Research Board (IHRB) provided additional funding to test and evaluate the bridge. This project directly addresses the IBRD goal of demonstrating (and documenting) the effectiveness of innovative materials and construction techniques for the construction of new bridge structures. Evaluation of performance was formulated through comparisons with design assumptions and recognized codes and standards including American Association of State Highway and Transportation Officials (AASHTO) specifications.
