Everyday Family Life: Dimensions, Approaches, and Current Challenges

2009

The aim of this systematic literature review was to identify, categorize, and evaluate the empirical research that has been conducted on everyday family life. Fifty-three empirically based articles focusing on everyday family life were included in the analysis, which focused on the conceptual, empirical, and theoretical content. According to our review, everyday family life comprises three dimensions: emotions, actions, and temporality. It is a continuously constructed process in which family members transmit emotions, engage in activities, and schedule timetables in the course of interactions with each other and with the wider social context. Three empirical or theoretical approaches were …

Do Sign Language Videos Improve Web Navigation for Deaf Signer Users?

2010

The efficacy of video-based sign language (SL) navigation aids to improve Web search for Deaf Signers was tested by two experiments. Experiment 1 compared 2 navigation aids based on text hyperlinks linked to embedded SL videos, which differed in the spatial contiguity between the text hyperlink and SL video (contiguous vs. distant). Deaf Signers’ performance was similar in Web search using both aids, but a positive correlation between their word categorization abilities and search efficiency appeared in the distant condition. In Experiment 2, the contiguous condition was compared with a text-only hyperlink condition. Deaf Signers became less disorientated (used shorter paths to find the tar…

Il miglioramento energetico nel recupero degli edifici storici. Applicazione al patrimonio architettonico palermitano

L'architettura storica può assumere un ruolo rilevante nel raggiungimento degli obiettivi europei di efficienza energetica per il settore edile, obiettivi che, tuttavia, devono essere compatibili con la conservazione del patrimonio storico e del suo valore culturale. A tal fine è necessario far riferimento ai caratteri specifici dell'architettura storica e alla sua dimensione locale. La presente tesi, sulla base di tale assunto, esamina le prestazioni energetiche degli edifici storici e il loro potenziale miglioramento, concentrandosi sul patrimonio architettonico di Palermo, caso di studio significativo per l'area mediterranea. La ricerca, condotta con riferimento sia alla scala urbana sia…

Image Segmentation by Deep Community Detection Approach

2017

International audience; To address the problem of segmenting an image into homogeneous communities this paper proposes an efficient algorithm to detect deep communities in the image by maximizing at each stage a new centrality measure, called the local Fiedler vector centrality (LFVC). This measure is associated with the sensitivity of algebraic connectivity to node removals. We show that a greedy node removal strategy, based on iterative maximization of LFVC, has bounded performance loss relative to the optimal, but intractable, combinatorial batch removal strategy. A remarkable feature of this method is the ability to segments the image automatically into homogeneous regions by maximizing…

An overview of incremental feature extraction methods based on linear subspaces

2018

Abstract With the massive explosion of machine learning in our day-to-day life, incremental and adaptive learning has become a major topic, crucial to keep up-to-date and improve classification models and their corresponding feature extraction processes. This paper presents a categorized overview of incremental feature extraction based on linear subspace methods which aim at incorporating new information to the already acquired knowledge without accessing previous data. Specifically, this paper focuses on those linear dimensionality reduction methods with orthogonal matrix constraints based on global loss function, due to the extensive use of their batch approaches versus other linear alter…

Using stage theorizing to make anti-phishing recommendations more effective

2018

Purpose This paper aims to review the behavioral phishing literature to understand why anti-phishing recommendations are not very effective and to propose ways of making the recommendations more effective. The paper also examines how the concept of stages from health communication and psychology can be used to make recommendations against phishing more effective. Design/methodology/approach This literature review study focused on the behavioral phishing literature that has relied on human subjects. Studies were excluded for reasons that included lacking practical recommendations and human subjects. Findings The study finds that phishing research does not consider where victims are residing…

Errors and Complications in SQL Query Formulation

2018

SQL is taught in almost all university level database courses, yet SQL has received relatively little attention in educational research. In this study, we present a database management system independent categorization of SQL query errors that students make in an introductory database course. We base the categorization on previous literature, present a class of logical errors that has not been studied in detail, and review and complement these findings by analyzing over 33,000 SQL queries submitted by students. Our analysis verifies error findings presented in previous literature and reveals new types of errors, namely logical errors recurring in similar manners among different students. We…

How Digital is Communication in Your Organization?

2006

Novel innovations in the area of digital media are changing the ways we communicate and organize. However, few practical measures exist for analysing the digitalisation of organizational communication as an intermediate factor in the initiatives to adopt new information and communication technologies (ICT). Building upon the genre theory of organizational communication, a categorization of communication forms, and quantitative measures we suggest such metrics and a measurement method. A case study applying them in an industrial organization suggests the method and metrics to be applicable for quantifying how new information systems affect to organizational communication as well as for antic…

Systematic literature review of E-learning capabilities to enhance organizational learning

2021

AbstractE-learning systems are receiving ever increasing attention in academia, business and public administration. Major crises, like the pandemic, highlight the tremendous importance of the appropriate development of e-learning systems and its adoption and processes in organizations. Managers and employees who need efficient forms of training and learning flow within organizations do not have to gather in one place at the same time or to travel far away to attend courses. Contemporary affordances of e-learning systems allow users to perform different jobs or tasks for training courses according to their own scheduling, as well as to collaborate and share knowledge and experiences that res…

THE FIRM-LEVEL EFFECTS OF SERVICE INNOVATION: A LITERATURE REVIEW

2010

Despite the importance of service innovation, its effects have been given relatively little explicit attention in the extant literature. Instead, researchers often implicitly assume that firm-level service innovation activities result in a number of positive financial and other effects. This paper conducts a systematic review of literature on the firm-level effects of service innovation and attempts to identify and categorize the effects suggested in the literature. The review reveals a considerable number of potential firm-level service innovation effects that have been discussed in extant research. We suggest that they may be divided into five effect categories: (1) business process effec…
