Eccesso di scelta e stress decisionale tra cognizione ed emozione
2008
Partendo da una breve rassegna della recente letteratura psicologica sui limiti cognitivi, emozionali e motivazionali della presa di decisioni, il presente contributo segnala la necessità di rivedere criticamente la diffusa convinzione secondo cui avere la possibilità di scegliere è sempre vantaggioso e gratificante per l’individuo. La sovrabbondanza di decisioni richieste dalla società odierna rischia, infatti, di tradursi in una stressante “tirannia di troppa scelta”.
La "razionalità" delle vittime di estorsione e l'impatto dell'overload informativo
2016
Il capitolo presenta un breve excursus tra le contrapposte interpretazioni del fenomeno mafioso e in particolare di quello estorto. Prende poi in considerazione i concetti di incertezza, rischio e overload informativo per vedere come sono stati trattati dalla teoria sociologica contemporanea e come è possibile utilizzare tali concetti nell'interpretazione dello stato delle vittime di estorsione. Si analizzano infine la prospettiva culturista nella sua versione 2.0 e gli effetti dell'overload informativo sulle vittime. The chapter presents a brief excursus between the opposing interpretations of the mafia phenomenon and in particular of the extorted one. It then takes into consideration the …
Factors mediating social media-induced fear of missing out (FoMO) and social media fatigue: A comparative study among Instagram and Snapchat users
2022
The proliferation of social media platforms has provided researchers with ample opportunities to explore the implications of these platforms' positive and negative use. Focusing on the latter, the literature has highlighted the severe implications of the fear of missing out (FoMO) and its associations with negative aspects of social media use, such as the problematic use of social media, phubbing, and reduced well-being. Our study investigates the association between FoMO and social media fatigue, which is mediated by information and communication overload, online subjective well-being (OSWB), and compulsive social media use (compulsive use). The proposed model is grounded strongly in self-…
On the use of ionic liquids as mobile phase additives in high-performance liquid chromatography. A review.
2015
The popularity of ionic liquids (ILs) has grown during the last decades in several analytical separation techniques. Consequently, the number of reports devoted to the applications of ILs is still increasing. This review is focused on the use of ILs (mainly imidazolium-based associated to chloride and tetrafluoroborate) as mobile phase additives in high-performance liquid chromatography (HPLC). In this approach, ILs just function as salts, but keep several kinds of intermolecular interactions, which are useful for chromatographic separations. Both cation and anion can be adsorbed on the stationary phase, creating a bilayer. This gives rise to hydrophobic, electrostatic and other specific in…
65 Science reboot. Creation of an evidence-based literature by increasing the use of regional languages in science
2019
Objectives English as an International Language is widely used in science. Unfortunately, scientific information space is oversaturated by using International Language, while Regional Languages remain informatively poor. The oversaturation leads to the information overload 1–4 , reducing the quality of information and data interpretation. At the same time, non-English speaking countries publish new studies in regional journals, causing contrary effect – information deficiency in English. 5 Similarly to RCSB PDB and NCBI, the authors suggest to create a novel scientific database in order to: - Enrich the regional languages allowing them to be competitive; - Concentrate on the evidence-based …
Social media overload, exhaustion, and use discontinuance : Examining the effects of information overload, system feature overload, and social overlo…
2020
While users’ discontinuance of use has posed a challenge for social media in recent years, there is a paucity of knowledge on the relationships between different dimensions of overload and how overload adversely affects users’ social media discontinuance behaviors. To address this knowledge gap, this study employed the stressor–strain–outcome (SSO) framework to explain social media discontinuance behaviors from an overload perspective. It also conceptualized social media overload as a multidimensional construct consisting of system feature overload, information overload, and social overload. The proposed research model was empirically validated via 412 valid questionnaire responses collecte…
When is More Really More? The Effect of Brands on Choice Overload in Adolescents
2021
Research on choice overload with adult participants has shown that the presence of a brand significantly mitigates the phenomenon. The aim of this study is to investigate whether these findings can be expanded to a population of adolescents, where it has already been shown that choice overload occurs in a similar way as adults. We present evidence from two studies that when facing either a large or a small amount of choice options that are associated with brand names, choice overload disappears among adolescents. Conversely, when no brands are associated to the choice options, adolescents report choice overload, that is a greater dissatisfaction, difficulties, and regret with larger (versus…
How much choice is "good enough"? Moderators of information and choice overload
2021
In today’s world, people face an abundance of information and a great number of choices both in important domains, such as health care, retirement, and education, and in less important domains, such as the choice of breakfast cereal or chocolate. Choice overload and information overload have strong negative effects on many important decision- making aspects such as processing and using information, the motivation to act, the quality of choices, and post- choice feelings, which are discussed in Chapter 43 in this volume in more detail. However, small choice and information sets are not always optimal either. Several variables– – such as information usage, decision accuracy, motivation to cho…
A VIRTUAL HUB BROKERING APPROACH FOR INTEGRATION OF HISTORICAL AND MODERN MAPS
2016
Geospatial data are today more and more widespread. Many different institutions, such as Geographical Institutes, Public Administrations, collaborative communities (e.g., OSM) and web companies, make available nowadays a large number of maps. Besides this cartography, projects of digitizing, georeferencing and web publication of historical maps have increasingly spread in the recent years. In spite of these variety and availability of data, information overload makes difficult their discovery and management: without knowing the specific repository where the data are stored, it is difficult to find the information required and problems of interconnection between different data sources and th…
Rationale and Design of the Efficacy of a Standardized Diuretic Protocol in Acute Heart Failure Study
2021
AIMS: Although acute heart failure (AHF) with volume overload is treated with loop diuretics, their dosing and type of administration are mainly based upon expert opinion. A recent position paper from the Heart Failure Association (HFA) proposed a step-wise pharmacologic diuretic strategy to increase the diuretic response and to achieve rapid decongestion. However, no study has evaluated this protocol prospectively. METHODS AND RESULTS: The Efficacy of a Standardized Diuretic Protocol in Acute Heart Failure (ENACT-HF) study is an international, multicentre, non-randomized, open-label, pragmatic study in AHF patients on chronic loop diuretic therapy, admitted to the hospital for intravenous …
