Botulinum Toxin Is Effective in the Management of Neurogenic Dysphagia. Clinical-Electrophysiological Findings and Tips on Safety in Different Neurol…
2017
Background and Aims: Neurogenic dysphagia linked to failed relaxation of the upper esophageal sphincter (UES) can be treated by injecting botulinum toxin (BTX) into the cricopharyngeal (CP) muscle. We compared the effects of this treatment in different neurological disorders with dysphagia, to evaluate its efficacy over time including the response to a second injection. Materials and Methods: Sixty-seven patients with neurogenic dysphagia associated with incomplete or absent opening of the UES (24 with brainstem or hemispheric stroke, 21 with parkinsonian syndromes, 12 with multiple sclerosis, and 10 with spastic-dystonic syndromes secondary to post-traumatic encephalopathy) were treated wi…
In-process tool-failure detection by means of AR models
1997
The present paper proposes a cutting tool breaking and chipping detection system for continuous and interrupted cutting, based on the analysis of the cutting force componentsFx andFy. A multifactorial experimental design has been carried out, to take account of the variability of the force signal. An adaptive signal processing algorithm is proposed, which detects catastrophic failure when at least one component deviates outside an estimated oscillation band for a time duration longer than a prefixed interval. The algorithm has been implemented on a four-microprocessor transputer board. Several tests confirmed the validity of the approach for detecting breaking and chipping phenomena in a fe…
Collision Orbits in the Isosceles Rectilinear Restricted Problem
1995
In the study of the Collinear Three-Body Problem, McGehee (1974) introduced a new set of coordinates which had the effect of blowing up the triple collision singularity. Subsequently, his method has been used to analyze some other collision or singularities. Recently, Wang (1986) introduced another transformation which differs from the McGehee’s coordinates in the fact that the blowing-up factor is now the potential function, U, instead of the moment of inertia, I. Meyer and Wang (1993) have applied this method to the Restricted Isosceles Three-body Problem with positive energy and Cors and Llibre (1994) to the hyperbolic restricted three-body problem. In this paper we study the singulariti…
Smartphone Usage Among Millennial in Finland and Implications for Marketing Segmentation Strategies: Lessons for Nigeria
2018
The study examines smart phone usage by millennials based on different criteria of operating system, Wi-Fi, text messaging, internet surfing and social media. The study used quantitative methodology and data were gathered with online questionnaires with 391 young smartphone users in Finland. The Millennial were clustered into five levels. The results reveal the prominent status of profiling in a developed market and how marketers in emerging markets can apply segmentation and targeting strategies using instant messaging, text messages, email, mobile app, gamification and social media based on the profile of each segment. Nigerian policy makers should adopt a framework to make smartphone aff…
Facing natural disasters through the endorsement of authoritarian attitudes
2020
Abstract We analyzed the relations between exposure to news describing a natural disaster and right-wing authoritarianism (RWA) with 241 Italian adults, surveyed twice, before and after a severe earthquake. Our results were compatible with the idea that the exposure to earthquake news led to an increase in RWA among people who had low, but not among who had relatively high, authoritarian levels before the event. We discuss the findings in terms of compensatory control, and highlight strengths and limitations of the study.
The correlation between right-wing authoritarianism and social dominance orientation: The moderating effects of political and religious identity
2008
In a secondary analysis performed on a representative sample of the Italian population (N = 887), we examined the correlation between right-wing authoritarianism (RWA) and social dominance orientation (SDO), analyzing the moderating effect exerted on such correlation by political interest and religion importance. RWA and SDO showed a positive, significant correlation (r = .38), moderated by political interest (which heightened it) and religion importance (which lowered it). Limits, implications, and possible developments of the research are discussed.
On the ideological consistency between right-wing authoritarianism and social domince orientation.
2007
Abstract The authors argue that cross-national variation in the association between right-wing authoritarianism (RWA) and social dominance orientation (SDO) depends upon the degree to which political systems are organized along a single explicitly ideologically articulated left–right dimension. In societies where the political system is ideologized along a single dimension, RWA and SDO should be strongly positively correlated, and the magnitude of this association should be moderated by political identification. This hypothesis was tested in Italy, a society where the political system is highly ideologized, using analyses of concurrent data from student (N = 148) and community samples (N = …
Spanish Adaptation of the Left-Wing Authoritarianism Index
2021
Notwithstanding long-simmering controversies around the construct, several studies have gathered consistent evidence of authoritarian attitudes among left-wing voters and activists. Recently, Costello et al. (Clarifying the structure and nature of left-wing authoritarianism. Journal of Personality and Social Psychology, 2021) validated, in the English-speaking context, a three-factor scale to measure left-wing authoritarianism, as well as two shortened versions of the same scale (Costello & Patrick, Development and initial validation of two brief measures of left-wing authoritarianism: A machine learning approach, 2021; composed of 39, 25 and 13 items, respectively). In this article, we use…
Societal Threat to Safety, Compensatory Control, and Right-Wing Authoritarianism
2014
We analyzed directly and indirectly the relationships between societal threat to safety, perceived control, and the increase in right-wing authoritarianism (RWA) in two studies. In Study 1 (national sample of the Italian population, N=1,169), we performed a longitudinal analysis structured into three waves (January 2003, September 2004, and January 2005). A moderated regression analysis showed that RWA increased from 2003 to 2005 as a function of perceived societal threat to safety more among low- than among high RWA scorers. In experimental Study 2 (Italian university students, N=131) a moderated mediation model showed loss of perceived control to mediate the relation between societal thre…
A new perspective of innovation toward a non-contact society - Amazon's initiative in pioneering growing seamless switching
2022
This paper elucidates the inside of the black box of Amazon's unique research and development (R&D) dynamism that made it the world's top R&D leader by transforming “routine or periodic alterations” into “significant improvement” during the R&D process. This dynamism also succeeded in transforming the COVID-19 pandemic period into a springboard for new innovation, leading to Amazon's notable growth notwithstanding the pandemic. An empirical analysis using a techno-economic approach focusing on Amazon's endeavor to develop a series of advanced digital fashions (ADFs) and online-based luxury brands (neo-luxury) before and during the COVID-19 pandemic was conducted. Amazon became a global appa…
