Une application mobile pour les victimes d'intimidation par les pairs : examen des récits d'expérience et perceptions d'utilité.

Au Canada, la prévalence de l'intimidation par les pairs (IPP) est estimée à environ 20 %. L'IPP est associée à de nombreuses difficultés sur le rendement scolaire et le fonctionnement émotionnel, cognitif et comportemental de la victime. Afin de s'investir dans la lutte contre l'IPP, le Québec a promulgué en 2012 la Loi visant à lutter contre l'intimidation et la violence à l'école. Ainsi, les écoles ont pour obligation d'instaurer un plan d'action contre l'intimidation. Toutefois, les services d'aide aux victimes sont parfois limités. C'est pourquoi l'application mobile « +Fort » a été développée. +Fort vise à soutenir les victimes d'IPP à réduire leurs expériences et à prévenir les difficultés associées. Le présent mémoire a trois objectifs: (1) décrire l'expérience des victimes d'IPP ayant utilisé +Fort pendant quatre semaines, (2) effectuer une première appréciation de l'utilité de +Fort à partir des récits des victimes et (3) décrire comment +Fort soutien les jeunes à réduire leurs expériences d'intimidation. Des entrevues semi-dirigées ont été menées auprès de 12 victimes d'IPP (12 à 16 ans) de la région de Montréal puis analysées thématiquement. Les résultats suggèrent que +Fort agirait comme un facilitateur dans les démarches de changement des victimes pour réduire l'IPP. Les ressources offertes par +Fort procureraient aussi une impression de soutien aux victimes qui influencerait ensuite leur désir et leur motivation à entreprendre des actions pour que cesse l'intimidation. Ainsi, les technologies mobiles représenteraient une plateforme attrayante pour soutenir le mieux-être des jeunes vivant de l'intimidation.

RMAC-M: Extending the R-MAC Protocol for an Energy Efficient, Delay Tolerant Underwater Acoustic Sensor Network application with a mobile data mule node

One of the major applications of underwater acoustic sensor networks (UWASN) is ocean environment monitoring. Employing data mules is an energy efficient way of data collection from the underwater sensor nodes in such a network. A data mule node such as an autonomous underwater vehicle (AUV) periodically visits the stationary nodes to download data. By conserving the power required for data transmission over long distances to a remote data sink, this approach extends the network life time. In this paper we propose a new MAC protocol to support a single mobile data mule node to collect the data sensed by the sensor nodes in periodic runs through the network. In this approach, the nodes need to perform only short distance, single hop transmission to the data mule. The protocol design discussed in this paper is motivated to support such an application. The proposed protocol is a hybrid protocol, which employs a combination of schedule based access among the stationary nodes along with handshake based access to support mobile data mules. The new protocol, RMAC-M is developed as an extension to the energy efficient MAC protocol R-MAC by extending the slot time of R-MAC to include a contention part for a hand shake based data transfer. The mobile node makes use of a beacon to signal its presence to all the nearby nodes, which can then hand-shake with the mobile node for data transfer. Simulation results show that the new protocol provides efficient support for a mobile data mule node while preserving the advantages of R-MAC such as energy efficiency and fairness.

Evaluating business value of IT towards optimisation of the application portfolio

Information technology has become heavily embedded in business operations. As business needs change over time, IT applications are expected to continue providing required support. Whether the existing IT applications are still fit for the business purpose they were intended or new IT applications should be introduced, is a strategic decision for business, IT and business-aligned IT. In this paper, we present a method which aims to analyse business functions and IT roles, and to evaluate business-aligned IT from both social and technical perspectives. The method introduces a set of techniques that systematically supports the evaluation of the existing IT applications in relation to their technical capabilities for maximising business value. Furthermore, we discuss the evaluation process and results which are illustrated and validated through a real-life case study of a UK borough council, and followed by discussion on implications for researchers and practitioners.

Calculating the application criticality and business risk from technology obsolescence

The problem of technology obsolescence in information intensive businesses (software and hardware no longer being supported and replaced by improved and different solutions) and a cost constrained market can severely increase costs and operational, and ultimately reputation risk. Although many businesses recognise technological obsolescence, the pervasive nature of technology often means they have little information to identify the risk and location of pending obsolescence and little money to apply to the solution. This paper presents a low cost structured method to identify obsolete software and the risk of their obsolescence where the structure of a business and its supporting IT resources can be captured, modelled, analysed and the risk to the business of technology obsolescence identified to enable remedial action using qualified obsolescence information. The technique is based on a structured modelling approach using enterprise architecture models and a heatmap algorithm to highlight high risk obsolescent elements. The method has been tested and applied in practice in three consulting studies carried out by Capgemini involving four UK police forces. However the generic technique could be applied to any industry based on plans to improve it using ontology framework methods. This paper contains details of enterprise architecture meta-models and related modelling.

An Analysis of the Telecommunications Business in China by Linear Regression

In this paper, we study the influence of the National Telecom Business Volume by the data in 2008 that have been published in China Statistical Yearbook of Statistics. We illustrate the procedure of modeling “National Telecom Business Volume” on the following eight variables, GDP, Consumption Levels, Retail Sales of Social Consumer Goods Total Renovation Investment, the Local Telephone Exchange Capacity, Mobile Telephone Exchange Capacity, Mobile Phone End Users, and the Local Telephone End Users. The testing of heteroscedasticity and multicollinearity for model evaluation is included. We also consider AIC and BIC criterion to select independent variables, and conclude the result of the factors which are the optimal regression model for the amount of telecommunications business and the relation between independent variables and dependent variable. Based on the final results, we propose several recommendations about how to improve telecommunication services and promote the economic development.

A web application for follow-up of results from a mobile device test battery for parkinson’s disease patients

Background: A test battery consisting of self-assessments and motor tests (tapping and spiral drawing) was developed for a hand computer with touch screen in a telemedicine setting. Objectives: To develop and evaluate a web-based system that delivers decision support information to the treating clinical staff for assessing PD symptoms in their patients based on the test battery data. Methods: The test battery is currently being used in a clinical trial (DAPHNE, EudraCT No. 2005-002654-21) by sixty five patients with advanced Parkinson’s disease (PD) on 9991 test occasions (four tests per day during in all 362 week-long test periods) at nine clinics around Sweden. Test results are sent continuously from the hand unit over a mobile net to a central computer and processed with statistical methods. They are summarized into scores for different dimensions of the symptom state and an ‘overall test score’ reflecting the overall condition of the patient during a test period. The information in the web application is organized and presented graphically in a way that the general overview of the patient performance per test period is emphasized. Focus is on the overall test score, symptom dimensions and daily summaries. In a recent preliminary user evaluation, the web application was demonstrated to the fifteen study nurses who had used the test battery in the clinical trial. At least one patient per clinic was shown. Results: In general, the responses from nurses were positive. They claimed that the test results shown in the system were consistent with their own clinical observations. They could follow complications, changes and trends within their patients. Discussion: In conclusion, the system is able to summarise the various time series of motor test results and self-assessments during test periods and present them in a useful manner. Its main contribution is a novel and reliable way to capture and easily access symptom information from patients’ home environment. The convenient access to current symptom profile as well as symptom history provides a basis for individualized evaluation and adjustment of treatments.

Mobile Assisted Language Learning : A Literature Review

Mobile assisted language learning (MALL) is a subarea of the growing field of mobile learning (mLearning) research which increasingly attracts the attention of scholars. This study provides a systematic review of MALL research within the specific area of second language acquisition during the period 2007 - 2012 in terms of research approaches, methods, theories and models, as well as results in the form of linguistic knowledge and skills. The findings show that studies of mobile technology use in different aspects of language learning support the hypothesis that mobile technology can enhance learners’ second language acquisition. However, most of the reviewed studies are experimental, small-scale, and conducted within a short period of time. There is also a lack of cumulative research; most theories and concepts are used only in one or a few papers. This raises the issue of the reliability of findings over time, across changing technologies, and in terms of scalability. In terms of gained linguistic knowledge and skills, attention is primarily on learners’ vocabulary acquisition, listening and speaking skills, and language acquisition in more general terms.

Assessment of business incubators green performance: A framework and its application to Brazilian cases

The lack of proposals to evaluate the greening of business incubators or even of elementary discussions about the relations between incubators and the environment becomes apparent when researching this topic in the most prestigious scientific sources. To address this gap, this article reviews the literature on green management and smaller enterprises, business incubator performance and the greening of business incubators. This conceptual big-picture was used to identify variables relevant to the construction of a framework for assessing business incubators green performance. This framework was applied to six business incubators in Brazil. The results show the appropriated applicability of this framework. Furthermore, the empirical research led to the formulation of environmental maturity levels in order to classify business incubators performance. This paper seeks to offer a starting point for discussion and a proposal regarding the role of business incubators in a more sustainable society. © 2011 Elsevier Ltd. All rights reserved.

Improving business innovation and research through the application of neuromarketing with ethics: a framework

The objective of this paper is to analyse and to discuss the ethical issues in the field of research known as neuromarketing, a tool used to improve innovation in companies. It uses techniques available to neuroscientists, both newer and more sophisticated ones along with traditional ones, but now for new purposes. From the beginning, this new area has evoked discussions about ethical aspects related to the results presented. Despite the unrestricted controversy surrounding the theme, few studies have discussed ethical issues involved in this line of research in a pragmatic manner. In this sense, this paper seeks to analyse and discuss ethical issues in neuromarketing research through a literature review and the proposal for a framework of ethical mapping. This framework revealed the ethical implications that would be most prominent in certain research situations: the purpose of utilising neuromarketing techniques, organisational type, and industrial sector, among others.

Sviluppo di applicazioni mobile: confronto fra piattaforme native e tecnologie web utilizzando iOS e PhoneGap come caso di studio

Negli ultimi anni il mondo del mobile computing ha avuto una vera e propria crescita esponenziale grazie soprattutto all'entrata in scena dello smartphone. In realtà, per essere più precisi, è bene bene sottolineare che gli smartphone esistevano già da tempo ma il loro utilizzo era in particolar modo indirizzato ai professionisti per il quale era, ma continua ad essere tutt'oggi, un valido supporto in campo lavorativo, basti pensare all'importanza della comunicazione via e-mail e non solo. Seppur comunque fossero già presenti da tempo, i primi smartphone non godevano di certo di un touch-screen sofisticato come quello odierno nè in essi erano presenti funzionalità tipiche dei dispositivi che troviamo ad oggi sul mercato. Una svolta decisiva è stata segnata dall'introduzione dell'iPhone e successivamente dell'AppStore, grazie a questi la programmazione per i dispositivi mobile ha preso sempre più piede diventando un vero e proprio business. In un secondo momento alla programmazione nativa si affiancarono le tecnologie web. Questo mio lavoro di tesi si pone l'obiettivo di studiare in primis la struttura, caratteristiche e peculiarità del sistema operativo iOS e analizzare il framework PhoneGap al fine di riuscire a confrontarne i vari aspetti fondamentali anche attraverso lo sviluppo di piccole applicazioni. Così facendo, quindi scendendo nei dettagli di quelle che possono essere le differenze rilevanti, mi pongo l'obiettivo di valutarne relativi pro e contro al fine di fare una scelta del tutto personale tra iOS e PhoneGap.

Business chat: sviluppo e implementazione

In questa tesi si vuole parlare dello sviluppo e dell'implementazione di un'applicazione per smartphone. L'applicazione in questione si chiama BusinessChat, è stata sviluppata per Android e utilizza sia lato server, sia lato Client. BusinessChat è un applicazione che mette in contatto consumatori e gestori di attività. Lo scopo dell'app è quindi quello di permettere al consumatore, di comunicare con il business in maniera più immediata, semplice e diretta. Per quanto riguarda il business può utilizzare quest'app sia per fornire un servizio al proprio cliente che per utilizzarla per pubblicizzare la propria attività, ad esempio con messaggi in broadcast a tutti i propri contatti (questa funzione non è ancora presente nella nostra applicazione, ma verrà aggiunta in un breve futuro). L'utente può ricercare, attraverso l'uso di una mappa, una particolare attività, ed eventualmente mettersi in contatto con lei, ad esempio, se ciò che cerchiamo è un ristorante, potremmo voler sapere se questa sera sono ancora disponibili dei posti liberi nel proprio locale, oppure se ad esempio volessimo ordinare delle pizze da asporto dalla nostra pizzeria di fiducia o sapere se sono attrezzati per gestire clienti allergici al glutine, o più semplicemente per conoscere l'orario di chiusura, tutto questo sarebbe possibile farlo attraverso pochissimi passi grazie a BusinessChat.
