Late-Adoptions: Assessing Parent-Child Relationship Through Free-Play Interaction and Attachment Representations
No full textAs suggested by various studies (Barone and Lionetti 2011; Ongari and Tomasi 2013; Pace et al. 2015; Steele et al. 2008), a secure maternal attachment state of mind can represent a protective factor against adverse outcomes associated with emotional deprivation and trauma, confirming adoption as a potential catch-up opportunity.
While attachment assessment allows to evaluate the internal representations of children and parents about their relationship, the observation of their interaction allows to focus on the dyadic quality of parent–child relationship (Sander 2007). Up to now, only a few studies have explored the quality of caregiver–child interaction in adoptive families (Garvin et al. 2012; Altenhofen et al. 2013; Van den Dries et al. 2012) and an even smaller number did so by involving the paternal figures.
To deepen the understanding of the relational functioning of families with late-adopted children, the aim of this study was to evaluate both the concordance of attachment in adoptive dyads (mother–children and father–children) and the relationship between attachment representations and parent–child interaction.
The sample was composed of 20 Italian adoptive families recruited through health services and authorized agencies for international adoptions. Children were aged between 4.5 and 8.5 years and the time spent in the adoptive family ranged from 1 to 3 years.
Dyadic emotional availability was assessed through the Emotional Availability Scales (EAS), adult attachment through the Adult Attachment Interview (AAI) and children attachment through the Manchester Attachment Story Task (MCAST).
Our results pointed out the presence of a relation between attachment representations of late-adopted children and their adoptive mothers (75%, K = 0.50, p = .025). In addition, we found that both insecure children and mothers showed lower levels of EA than secure ones. Some explanations are presented about why, in the early post-adoption period, child attachment patterns and dyadic emotional availability seem to be arranged on different frameworks for the two parental figures
International late-adoption: assessing parent-child relationship through free-play interaction and attachment representations.
No full textIntroduction: The adoptive experience is considered an opportunity to experience a new
relational environment that offers the possibility to revise early insecure or disorganized
attachment in abused and/or neglected children (Van IJzendoorn & Juffer 2006; Pace et
al., 2012). While attachment assessment allows the internal representations of children and
parents about their relationship to be evaluated, the observation of their interaction
allows the specific way in which the two individuals co-construct the reality of their
unique dyad (Sander 2007) to be looked at. Several studies have found a relationship
between the assessment of interaction through dyadic emotional availability and infant
attachment, although the strength of this association has been proved to be modest (Van
Den Dries, Juffer et al. 2012). The aim of this study was to evaluate the relationship between attachment representations and dyadic emotional availability, so as to deepen the understanding of the relational functioning of families with late-adopted children.
Method: The sample was composed of 18 Italian adoptive families recruited
through health services and authorized agencies for international adoptions. Children
were aged between 4.5 and 8.5 years and the time spent in the adoptive family ranged
from 1 to 3 years. Measures: Dyadic emotional availability was assessed through the Emotional
Availability Scales - EAS (Biringen 2008), adult attachment through the Adult
Attachment Interview - AAI (George, Kaplan & Main 1985) and child attachment
through the Manchester Attachment Story Task - MCAST (Green, Stanley, Smith, &
Goldwyn 2000).
Results and discussion: The attachment distribution of the parents shows an
overrepresentation of insecure categories. The distribution of child attachment is 56%
Secure (with respect to at least one parent), 22% Insecure, and 22% Disorganized (with
respect to at least one parent). Results reveal a matching between parental attachment
models and children attachment patterns and a weak association between parental
emotional availability and adult attachment classifications. These outcomes indicate that insecure and disorganized attachment patterns of late-adopted children in the first 3 years after adoption may change; nonetheless, parental attachment security is not a sufficient condition. These data also suggest that free-play interactions may not necessarily lead to distress and therefore to the activation of the attachment/care-giving system, offering a possible explanation for the weak correlation between emotional availability and child attachment
El diseño artístico como estrategia para el aprendizaje de las funciones
Full text linkLa propuesta que se expone está dirigida a utilizar la recreación y creación artística como una estrategia para el aprendizaje matemático. Los alumnos realizan diseños artísticos dibujando con funciones y ecuaciones de lugares geométricos, usando como recurso didáctico graficadores y programas de geometría dinámica. Las posibilidades informáticas permiten la manipulación de las funciones modificando sus gráficas según las variaciones de sus parámetros y argumentos, restringiendo sus dominios y planteando las ecuaciones adecuadas a ciertas condiciones del diseño. Los alumnos deben aprender a transformar las ecuaciones de las funciones al tipo de coordenadas que el programa utilizado acepta, por lo que pueden identificarse ecuaciones implícitas, explícitas, paramétricas, y funciones en coordenadas polares. Los diseños se realizan en graficadores del tipo del Graphmática o Winplots, recomendándose aquéllos graficadores menos potentes porque exigen un trabajo matemático más profundo. El diseño es de creación libre en la primera etapa y luego se realizan actividades algebraicas en forma guiada, en base a un diseño dado, lo que constituye una tarea para la ejercitación con un fin determinado. Asimismo estas acciones pueden ser evaluadas por el docente desde la visión matemática, además de la artística. El uso de los comandos adecuados de ciertos programas de geometría dinámica permite la búsqueda de lugares geométricos, los que serán un recurso valioso para la creación. Si propiciamos la observación del entorno y proponemos la matematización de imágenes para ser recreadas utilizando funciones y ecuaciones, que permitan la graficación de rectas, parábolas, funciones polinómicas, funciones trigonométricas, circunferencias, círculos, elipses, cicloides, epicicloides e hipocicloides, podemos fundamentalmente crear ,generando la construcción de aprendizajes, la interpretación de conceptos desde distintos registros semióticos , el registro de ideas, la elaboración de conclusiones , la comunicación de los logros y dificultades, , la creación de obras artísticas en diseños computacionales, pintura y escultura, y fundamentalmente, la institucionalización de nuevos contenidos.Fil: Piermattei, C..

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
