Towards text simplification for poor readers with intellectual disability: When do connectives enhance text cohesion?
2013
Abstract Cohesive elements of texts such as connectives (e.g., but, in contrast) are expected to facilitate inferential comprehension in poor readers. Two experiments tested this prediction in poor readers with intellectual disability (ID) by: (a) comparing literal and inferential text comprehension of texts with and without connectives and/or high frequency content words (Experiment 1) and (b) exploring the effects of type and familiarity of connectives on two-clause text comprehension by means of a cloze task (Experiment 2). Neither the addition of high frequency content words nor connectives in general produced inferential comprehension improvements. However, although readers with ID wer…
Relational cohesion between users and smart voice assistants
2021
Purpose This study aims to examine users’ affective relationships with smart voice assistants (SVAs) and aims to analyze how these relationships explain user engagement behaviors toward the brands of SVAs. Drawing on relational cohesion theory, it proposes that cohesion between users and SVAs influences brand engagement behaviors, that is, continuing purchasing other products of the brand, providing knowledge to the brand and referring the brand. Design/methodology/approach Data from a survey of 717 US regular SVA users confirm the validity of the measurement scales and provide the input for the covariance-based structural equation modeling. Findings The results demonstrate that frequent u…
Cohesive–frictional interface constitutive model
2009
AbstractIn the framework of numerical analysis of joined bodies, the present paper is devoted to the constitutive modeling, via an interface kinematic formulation, of mechanical behaviour of internal adhesive layers. The proposed interface constitutive model couples a cohesive behaviour, based on the damage mechanics theory, with a frictional one, defined in a non-associative plasticity framework. Namely, the interface formulation follows the transition of the adhesive material from the sound elastic condition to the fully cracked one. This formulation is able to model, by means of a specific interpretation of the damage variable and in a relevant mathematical setting, the interface interme…
The Influence of Business Ecosystems on Innovation-Based Industries: A Research on the Mechanical Sector in Italy
2018
The business ecosystem perspective can be considered as a more advanced point of view for interpreting the development of local economic systems, if compared to more traditional concepts such as clusters, industrial districts, local or regional systems, and local networks. The business ecosystem perspective allows to better highlight the adaptive and evolutionary nature of local systems in front of the changing external environment and dynamics on national and international markets. The aim of the research was to analyze the key characteristics of firms belonging to a local business ecosystem specialized on an innovation-driven industry – the mechanical sector – in order to verify which kin…
Mechanical and cohesion properties of brass plated steel cords in a sulphurizing environment
1986
The mechanical and cohesion properties of brass plated steel cords have been investigated in dry hydrogen sulphide between 25 and 450° C. The extents of elastic and plastic regions, obtained from slow strain rate technique data have been defined, and the preferential site of decohesion tends to be the brass-steel interface.
Dynamic Mechanical Measurements of Epoxy Matrix-Silica Nanocomposites II
2009
The mechanical properties of epoxy-silica nanocomposites have been studied; the silica nanosphere fillers used were un-functionalised, functionalised with amine, with epoxy, or a mixture of both kinds. Dynamic mechanical analysis measurements revealed an increase in the shear storage modulus, for all samples with a filler content of 3–5%. Improvements were observed in the glassy and rubbery states, without affecting the glass transition temperature of the materials. Above these strengthening percentages, the mechanical properties began to deteriorate, but in all cases they remained superior to those of the pristine epoxy resin. For low strengthening percentages, samples reinforced with bot…
De la ley de barrios al diseño de políticas locales de empleo
2009
(Erm) de Manlleu, localidad de la provincia de Barcelona. La investigación forma parte de un conjunto de acciones integradas llevadas a cabo en el Erm a partir de la aplicación de la denominada Ley de Barrios, impulsada por el Gobierno catalán. La Ley facilita el desarrollo de actuaciones en el ámbito local, especialmente en el terreno urbanístico. Pero, como mostraremos, puede ser también un instrumento eficaz para desarrollar políticas de promoción del empleo ligadas al territorio. Un tipo de políticas que remite a la importancia que viene adquiriendo el ámbito local en cuestiones de empleo; y que se refleja en los numerosos estudios que se realizan en torno a la idea del desarrollo local…
Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo
2022
Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…
Medidas psicométricas de la cohesión en equipos de trabajo universitarios (Psychometric measures of cohesion in university work teams)
2019
La cohesión ha sido un concepto ampliamente estudiado en equipos deportivos y organizacionales, pero no ha sido estudiado en equipos de trabajo universitarios. Además se han usado medidas de la cohesión, como el Sociograma, que no han demostrado su validez de constructo. Este trabajo presenta dos estudios. En el primero, el objetivo es comprobar las evidencias de validez confirmatoria y fiabilidad del GEQ (Group Environmental Questionnaire) en equipos de trabajo universitarios y en él han participado 273 alumnos. En el segundo estudio, se quieren comparar las medidas de la cohesión a través de dos instrumentos: GEQ y Sociograma utilizando dos mediciones antes y después del trabajo grupal. E…
Percezione del funzionamento familiare e strategie di coping in madri di bambini affetti da neoplasia in fase trattamentale
2013
Il contributo presenta uno studio correlazionale sul rapporto tra specifiche strategie di coping di madri di bambini con neoplasia in fase trattamentale e la loro percezione del funzionamento familiare, in termini di coesione e adattabilita/flessibilita, muovendo dall’ipotesi che una relazione "virtuosa" tra le variabili considerate possa costituire una risorsa importante per la madre. Lo studio, che ha coinvolto un gruppo di 34 madri di bambini con neoplasia in fase di trattamento, ha previsto la somministrazione di due specifici strumenti: il Coping Orientation to the Problems Experienced -Nuova Versione Italiana (COPE-NVI), per rilevare le strategie di coping, e il Family Adaptability an…
