The role of perspective on students’ use of multiple documents to solve an openended Task

2013

AbstractMcCrudden & Schraw (2007) show how students’ interaction with a text is mediated by the instructions they are presented with. Specifically, perspective instructions prompt readers to use background knowledge to evaluate text from an assigned point of view. Research on perspective in single texts has demonstrated that readers confer relevance on text segments that are consistent with the assigned perspective (Pichert & Anderson, 1977). This work has tested the effects of perspective when reading conflicting information from multiple documents to perform an open-ended task, as well as has studied if the trustworthiness of a source exerts any influence on students’ decision to use info…

Equity-worthiness and equity-willingness: key factors in private equity deals

2014

While access to private equity funds (PEFs) provides a unique opportunity for firms to set up sturdy growth paths, how PEFs select companies is an unknown process to entrepreneurs and business owners. This study aims to offer insights regarding the private equity market to entrepreneurs searching for external capital. We analyzed a novel dataset of 240 pre-deal negotiations between small- and medium-sized Italian companies and a closed-end fund. Results indicate that the successful closing of a deal depends on more than just the target firm's equity-worthiness (i.e., the company's ability to meet the expectations of a private equity investor). In fact, there is another dimension: the target…

Mathematical models for assessment of vehicle crashworthiness: a review

2021

This article reviews approaches to mathematical modeling of a vehicle crash. The growing focus on vehicle and occupant safety in car crashes has triggered the need to study vehicle crashworthiness in the initial stages of vehicle development. The major motivation for this work is to support vehicle crashworthiness design during the product development process.The article is divided into two parts; the first one overviews existing mathematical models used to solve engineering problems. The second part describes modeling strategies applied for replicating non-linear vehicle crash event and occupant kinematics in an occupant protection loadcase. We also highlight alternative modeling strategie…

Understanding evolutionary processes that drive genome reduction requires determining the tempo (rate) and the mode (size and types of deletions) of gene losses. In this study, we analysed five endosymbiotic genome sequences of the gamma-proteobacteria (three different Buchnera aphidicola strains, Wigglesworthia glossinidia, Blochmannia floridanus) to test if gene loss could be driven by the selective importance of genes. We used a parsimony method to reconstruct a minimal ancestral genome of insect endosymbionts and quantified gene loss along the branches of the phylogenetic tree. To evaluate the selective or functional importance of genes, we used a parameter that measures the level of ad…

EGF and HGF levels are increased during active HBV infection and enhance survival signaling through extracellular matrix interactions in primary huma…

2008

The hepatitis B virus (HBV) is a major causative agent of chronic liver disease and subsequent liver cirrhosis worldwide. The reduced sensitivity of virus-infected liver cells to apoptosis may play a role in the failure to remove virus-infected cells and eventually promote viral chronicity. The purpose of our study was to investigate whether survival factors induced during compensatory liver regeneration may protect hepatocytes against apoptosis. We evaluated the serum levels of hepatocyte growth factor (HGF) and epidermal growth factor (EGF) in HBV-infected patients and found significant increases in HGF and EGF in patients with active virus infection. In primary human hepatocytes we show …

Effects of Equivalence Framing on the Perceived Truth of Political Messages and the Trustworthiness of Politicians

2017

Recent studies in psychology have shown that the framing of a message affects judgments about its truth, as negatively framed statements are perceived as more trustworthy than formally equivalent, positively framed statements. The current work examines this effect in the contexts of political communication and public opinion. The results of three experiments show that equivalence framing affects both the perceived truth of political messages and the trustworthiness of its source, and that one cause of this effect is that recipients have learned to associate negativity with news and positivity with persuasive communication through media exposure. Consequently, we find that positively framing…

Faculty Perception of Inclusion in the University: Concept, Policies and Educational Practices

2021

European universities must face the challenge of diversity and design inclusive practices to address it as part of their social responsibility. However, not all universities are doing the same in terms of diversity practices, so it is important to gather the perceptions of the protagonists. To this end, we have analysed university faculty’s perceptions using a mixed model with a concurrent methodological strategy, including an ad hoc questionnaire validated with 880 educators, as well as 17 semi‐structured interviews. The triangulation of these two instruments allowed us to analyse three key dimensions associated with the idea of attention to diversity in the university: diversity concept o…

Long-term working memory and interrupting messages in human – computer interaction

2004

The extent to which memory for information content is reliable, trustworthy, and accurate is crucial in the information age. Being forced to divert attention to interrupting messages is common, however, and can cause memory loss. The memory effects of interrupting messages were investigated in three experiments. In Experiment 1, attending to an interrupting message decreased memory accuracy. Experiment 2, where four interrupting messages were used, replicated this result. In Experiment 3, an interrupting message was shown to be most disturbing when it was semantically very close to the main message. Drawing from a theory of long-term working memory it is argued that interrupting messages ca…
