From research question to dissemination: how to design, analyse and present study results

2018

Today, the term “study” is very frequently used in quite a broad sense: survey, clinical trial, analysis, research and other terms with deeply different meanings are often generally indicated as “studies”. A “study” can be generally defined as a process composed of several actions aimed to verify one or more hypotheses (objectives), with the ultimate goal of sharing the answers (results) with a target audience, in the form of a scientific paper, presentation or poster.

Leadership – A Key Factor to a Succesful Organization – Part II

2013

Abstract Leadership is the well-known and often discussed process nowadays of influence exerted by one person, accepted and followed by all, over the other factors (human resource) that he works with, in order to reach the organizational goals. This research is the second part of a long cycle aimed to determine the knowledge and application of the leadership concept in the Romanian organizations considering the influences imposed by the external environment, often characterized by frequent changes. These changes may have positive or negative effects on organizations, and that is why organizations have to react fast in order to take advantage of opportunities and to protect from threats. We …

Heading at Enabling Settings for Learning

2021

The paper draws on two cases of learning settings that were converted to meet up-to-date educational requirements within these learning contexts. The authors address the role of stakeholder perspectives. Focusing on the learning situation, they present an articulation tool to aid dialogue between key stakeholder perspectives in a (re)design process. Dialogue is a way to figure out relevant issues and to establish the common ground between participants. The goal of a redesign process is that user requirements are well understood, and the design is embedded into local practices, informed of constraints and aware of potential opportunities regarding educational technology.

What Key Aspects Do ICOs Reveal About Their Businesses?

2020

AbstractBlockchain technologies disrupt industries by enabling decentralized and transactional data sharing across a network of untrusted participants, among others. Initial Coin Offerings (ICOs) are a novel form of crowdfunding through which hundreds of blockchain-enabled businesses manage to raise billions of dollars in total only in United States. However, there is a lack of understanding of the ICO phenomenon especially related to the business aspects. In this paper, we describe the results of an exploratory study of 91 ICOs and identify the key business model elements that ICOs reveal in their websites and whitepapers. Furthermore, we also note the immaturity and lack of transparency o…

Security in Modern Smart Cities: An Information Technology Perspective

2019

In a big and modern city, the security system is not a single-layered single module system. Instead, it consists of many layers with autonomous subsystems which are capable of interfacing reciprocally in an efficient and coordinated way horizontally and vertically. The design of such indigenous subsystems and ensuring tight interaction between them while taking into account high usability and resource utilization is not a simple task. In this regard, this article provides a comprehensive overview of the security systems in smart cities. We begin by introducing trends and key stakeholders in smart cities. Next, we provide examples of mass surveillance systems in developed countries like the …

Omni-Channel Intensity and Shopping Value as Key Drivers of Customer Satisfaction and Loyalty

2021

Omni-channel retailing consists of the complete alignment of the different channels and touchpoints that generate a seamless experience for consumers, allowing them to move freely through all channels. The consumer's perception of a seamless and consistent omni-channel experience is called intensity. This study reveals that this intensity in the shopping experience can offer value to consumers, and that intensity and shopping value also influence satisfaction and loyalty. We propose a relationship model that had been tested in a quantitative study with PLS, with a representative sample of buyers who had used the Click and Collect system. The main contribution of this study is to the literat…

Does "whole-word shape" play a role in visual word recognition?

2002

To analyze the impact of outline shape on visual word recognition, the visual pattern of the stimuli can be distorted by size alternation. Contrary to the predictions of models that rely on outline shape (Allen, Wallace, & Weber, 1995), the effect of size alternationwas greater for low-frequency words than for high-frequency words in a lexical decision task (Experiment 1). In Experiment 2, the effect of case type (lowercase vs. UPPERCASE) occurred for low-frequency words, but not for high-frequency words. The effect of neighborhood size was remarkably similar in the two experiments. The results can be readily explained in the framework of a resonance model (Grossberg & Stone, 1986), in whic…
