Implicit regulation for automotive variators

2001

A well-known practice uses mechanical variators to realize the so-called continuously variable transmissions (CVTs) for automotive application. A remarkable problem for one of the most used CVTs is given by the hydraulic control of the axial thrust on the half-pulleys that is necessary for torque transmission. It involves a heavy decrease in transmission efficiency. In the present paper, the possible production of the required axial thrust by a simple spring to eliminate hydraulic losses is analysed. It is shown that the power capacity of such a regulated variator is near to the maximum possible, and the belt torque loss is always considerably lower than the sum of the belt and pump losses…

How Relevant Are Risk Perceptions, Effort, and Performance Expectancy in Mobile Banking Adoption?

2018

This article provides a comprehensive overview of the adoption process using evidence from m-banking adoption in Pakistan. A survey design was used and 189 responses were received from across Pakistan and analyzed using Smart PLS application. Findings suggest that research on the effect of risk in the adoption process remains inconclusive. Contrarily, consumers have overcome many fears due to the usefulness, indispensability, high security features, and effort expended in the use of financial services delivered through m-banking. Perceived risk's (PR) direct influence was found to be generally weak. However, PR plays a major role in the pre-adoption process because it's weak and direct inhi…

Augmented Reality Applications: The Impact of Usability and Emotional Perceptions on Tourists’ App Experiences

2019

There is a rising amount of research contributing to the knowledgebase of Augmented Reality (AR) application usage. However, up until now there is no sound understanding about how the emotional perception of AR application users impact on different types of experience. This paper aspires to contribute to this gap by analysing the link between usability, emotional perception (i.e. entertainment, playfulness and enjoyment), two types of experience viz. action- and emotional experience and users’ intention to use the app in a travel context. 796 questionnaires show that emotional experience is driven by entertainment while action experience is mainly triggered by playfulness. However, only emo…

La influencia del medio televisivo en el proceso de socialización de la infancia

2008

El presente artículo trata de abordar la complejidad de la influencia del vi- sionado televisivo en el proceso de socialización de la infancia. Para ello, analizamos los presupuestos teóricos que están a la base de dicho proceso, profundizamos en el pa- pel que desempeña la televisión como agencia socializadora de la infancia al tiempo que centramos nuestra atención en las implicaciones pedagógicas para dicho periodo evolu- tivo. El artículo concluye con una serie de reflexiones pedagógicas y propuestas de me- jora que pretenden contribuir a la optimización de la realidad educativa.

Students’ Perception of Cell Phones Effect on their Academic Performance: A Latvian and a Middle Eastern University Cases

2021

This study is unique in its attempt to combine the Technology Acceptance Model (TAM) with external variables and the Information System Continuance Theory, in the context of mobile learning. It extends TAM with the external variables perceived mobility and perceived enjoyment. Mainly, students’ perception of cell phones effect on their academic performance is investigated. The study was conducted at two different universities—in Europe and the Middle East. Cell phone usage is analyzed from the perspective of mobile learning. The data in this study were collected from 103 students from the University of Latvia and 106 students from a Middle Eastern private American University. This study sho…

X-chromosomal retinitis pigmentosa (RP) frequently is caused by mutations in the retinitis pigmentosa GTPase regulator (RPGR) gene. We evaluated the potential of PTC124 (Ataluren, TranslamaTM) treatment to promote ribosomal read-through of premature termination codons (PTC) in RPGR. Expression constructs in HEK293T cells showed that the efficacy of read-through reagents is higher for UGA than UAA PTCs. We identified the novel hemizygous nonsense mutation c.1154T > A, p.Leu385* (NM_000328.3) causing a UAA PTC in RPGR and generated patient-derived fibroblasts. Immunocytochemistry of serum-starved control fibroblasts showed the RPGR protein in a dot-like expression pattern along the primary…

Data from the GIPEyOP online election poll for the 2015 Spanish General election.

2020

Abstract The general elections of 2015 in Spain took place in the middle of the Great Recession after several years of austerity economic policies. This election caused a political earthquake that shook the Spanish party system. During the campaign of that election, GIPEyOP (Elections and Public Opinion Research Group from University of Valencia) conducted a survey to collect relevant data about the electorate beliefs, intentions and motivations. This article describes the data set attained, which comprises 71 variables after removing, to ensure full anonymity, those variables that would potentially allow respondents to be identified. Respondents answered a self-administered online question…

Informal situated counselling in a school context†

2008

The institutional regulation of counselling conversations does not always provide optimal conditions for counselling. Many teachers experience that some “normal” conversations develop into conversations which are of a counselling nature. Conversations which resemble counselling can be optimal counselling opportunities. In this paper we describe and develop these counselling conversations, which we call Informal Situated Counselling. †An earlier version of this article has been published in Norsk Pedagogisk Tidsskrift [Journal of Norwegien Pedagogic].

E-Fairs: a Cyber-Physical System for Aggregation and Economy of Scale in e-Commerce

2018

In recent years, the e-commerce arena has deeply changed because of the advent of new business models and the growing weight of huge global actors like Amazon. Some business models create competition between users, and the product price tends to rise (e.g., online auctions); other models, including group-buying, make users cooperate, and the price tends to go down. The present study extends the group-buying model and proposes a cyber-physical system called e-fair, in which both sellers and buyers are grouped to negotiate on a specific product or service. E-fairs minimize the global purchase price and the shipping resources respectively with the aggregation of demand and supply as well as or…

Awareness and partitional information structures

1994

This is the first of two papers where we present a formal model of unawareness. We contrast unawareness with certainty and uncertainty. A subject is certain of something when he knows that thing; he is uncertain when he does not know it, but he knows he does not: he is consciously uncertain. On the other hand, he is unaware of something when he does not know it, and he does not know he does not know, and so on ad infinitum: he does not perceive, does not have in mind, the object of knowledge. The opposite of unawareness is awareness, which includes certainty and uncertainty. This paper has three main purposes. First, we formalize the concept of awareness, and introduce a symmetry axiom whic…
