La linea spezzata. Una ricostruzione critica dell'attuale deficit di coerenza
2021
Siamo nell’era della smemoratezza. Una smemoratezza prodotta dalla sovrabbondanza di informazioni, dalla pratica del multitasking, dalla propensione a demandare la conservazione dei ricordi ai device e ai cloud di cui facciamo uso ogni giorno. La fragilità della memoria ha spezzato la linea che congiungeva passato, presente e futuro, la linea che li attraversava e li rendeva coerenti. Ma lo ha fatto solo nella nostra testa, perché sul piano della realtà gli effetti delle scelte di ieri non smettono di presentarsi all’oggi. L’allargamento degli orizzonti culturali prodotto dalla globalizzazione ha ridotto tutti gli elementi del nostro panorama a dettagli lontani e indistinguibili. Ma lo ha f…
Preference Oriented Measurement of Advertising Response
2015
As the information overload and an extension of the mass media reduces the possibility to get the message to the target group, the firms have to increase their advertising budget to reach the same amount of ad contacts. To be sure, that they don’t waste the money, the companies more often use the instrument of pretesting the commercial campaign. The aim of this paper is to document the advantages of the conjoint-analysis (CA) as a technique for pretesting ads. To evaluate the possibility of using the CA we try in to measure in an empirical study, if informative and emotional ads have an influence on the preferences of the respondent.
Physical Activity and Exercise: Text Mining Analysis
2021
It is currently difficult to have a global state of the art vision of certain scientific topics. In the field of physical activity (PA) and exercise, this is due to information overload. The present study aims to provide a solution by analysing a large mass of scientific articles using text mining (TM). The purpose was to analyse what is being investigated in the PA health field on young people from primary, secondary and higher education. Titles and abstracts published in the Web of Science (WOS) database were analysed using TM on 24 November 2020, and after removing duplicates, 85,368 remained. The results show 9960 (unique) words and the most frequently used bi-grams and tri-grams. A co-…
Using Slack for computer-mediated communication to support higher education students’ peer interactions during Master’s thesis seminar
2018
Our study contributes to the research on computer-mediated communication in higher education by experimenting a modern communication tool called Slack. In particular, we consider using Slack to support students’ peer interactions during Master’s thesis work. For this purpose, we designed a case study that was executed in a Master’s thesis seminar course. During the course, all out-of-class communication was carried out by using Slack, instead of e-mails or learning management systems. After the course, we used a questionnaire to investigate how the students perceived Slack for asking for assistance, their intention to use Slack, and Slack’s ease of use. Furthermore, the questionnaire asked …
Two decades of the dark side in the information systems basket: suggesting five areas for future research
2016
Despite its benefits, information technology (IT) use is associated with serious negative effects on individuals. For example, technostress and IT addiction can harm IT users’ organizational performance and everyday well-being. Such dark side phenomena have become more evident since IT has transmuted into a major component of humans’ job routines and private lives. However, since current information systems (IS) research on the dark side is in an early and fragmented stage, there is a need for a synthesis. To address this need, we conducted a literature review of 37 articles published in the IS basket journals between 1995 and 2015. We detected four key phenomena: technostress, information …
Information management and complementary alternative medicine: the anatomy of information about CAMs through PubMed
2013
In recent years, there has been a growing interest about complementary and alternative medicine (CAM), and the use of CAM interventions has become more common among people. For these reasons, health professionals must be able to effectively manage information in this field of knowledge according to an evidence-based point of view. This study assessed the anatomy of the available information about CAMs using PubMed, to give practical instructions to manage information in this field. We also analyzed the anatomy of information according to each alternative medicine branch, narrow and broad search methods, subset filters for indexed-for-Medline and non-indexed citations, and different publicat…
Cognitive and Affective Consequences of Information and Choice Overload
2021
When interviewed in 1992 in Pittsburgh, Pennsylvania, the Nobel laureate Herbert Simon described a paradox at the heart of living in an economy that made every effort to design and produce ever more “choice alternatives” but that simultaneously allocated very little energy to encouraging people to devote the attention and time actually required to choose. He gave the example of a decision to buy a new house, commenting: “Before you even start the choice process, somebody has presented you with this, and this, and this house” (UBS, 1992). The overabundance of alternatives was lamented by Simon in 1992, when computing power was slower. It is all the more alarming in the modern and constantly …
An Iterative Information Retrieval Approach from Social Media in Crisis Situations
2019
During to past few years, social media have gained a pivotal role in crisis communication. Its usage has ranged from informing the public about the status of a crisis and what precaution need to be taken, to family members checking on the safety of loved ones. Despite the widespread use of social media in crises situations and the clear potential benefit from collecting potential critical information from social media, emergency management services (EMSs) are still reluctant to use social media as a source of information to improve their situational awareness. One of the reasons for the reluctance is that crises management are typically overloaded with information. Adding social media will …
The relationship between medical students’ media use and learning progress
2021
The acquisition of warranted domain-specific knowledge is essential for practical work in medicine. The medical field, however, suffers from 'information overload', and students and physicians rely...
A fuzzy methodology to alleviate information overload in elearning
2013
Some aspects of eLearning experience can be en- hanced in a very natural way by using the basic tools offered by fuzzy logic. As a matter of exam- ple, consider the uncontrolled growth of informa- tion produced in a collaborative-oriented context, in which each participant (e.g. students, teachers) is able to insert and share new contents (e.g. com- ments, texts) concerning a university course. All the incrementally added pieces of information can be evaluated in several ways: by the intervention of a “dictator” (e.g. the teacher), using a rating form, or even according to the frequency of access. As contents rapidly become unusable for the effects of information overload, basic tools of fu…
