Assessment of motor speech disorders online: A pilot study

We have conducted a preliminary validation of an Internet-based telehealth application for assessing motor speech disorders in adults with acquired neurological impairment. The videoconferencing module used NetMeeting software to provide realtime videoconferencing through a 128 kbit/s Internet link, as well as the transfer of store-and-forward video and audio data from the participant to the clinician. Ten participants with dysarthria following acquired brain injury were included in the study. An assessment of the overall severity of the speech disturbance was made for each participant face to face (FTF) and in the online environment, in addition, a 23-item version of the Frenchay Dysarthria Assessment (FDA) (which measures motor speech function) and the Assessment of Intelligibility of Dysarthric Speech (ASSIDS) (which gives the percentage word and sentence intelligibility, words per minute and a rating of communication efficiency) were administered in both environments. There was a 90% level of agreement between the two assessment environments for the rating of overall severity of dysarthria. A 70-100% level of agreement was achieved for 17 (74%) of the 23 FDA variables. On the ASSIDS there was a significant difference between the FTF and online assessments only for percentage word intelligibility. These findings suggest that Internet-based assessment has potential as a reliable method for assessing motor speech disorders.

A COMUNICAÇÃO VIA INTERNET NA INCLUSÃO E INTEGRAÇÃO DE DEFICIENTES AUDITIVOS: um estudo sobre a região do ABC / SP

O objetivo deste trabalho é compreender como a comunicação, através da Internet, é utilizada e construída, consideradas as questões da inclusão e integração de pessoas com deficiência auditiva. Analisam-se os conceitos sobre comunicação, inclusão e integração; a deficiência auditiva e seu significado para os indivíduos; a questão dos sites que tratam do assunto na Internet e o tipo de abordagem comunicacional utilizada dentro deste universo. A mensagem do transmissor (via Internet) - decodificada pelo receptor (deficiente auditivo) fornece ao receptor uma integração no mundo midiático capaz de fornecer uma inclusão adequada e uso facilitado da Internet pelo deficiente auditivo (receptor/a). A análise das respostas dos questionários aplicados aos usuários e aos transmissores de informações dos sites e as teorias utilizadas mostrarão se há dificuldades na construção de novas mensagens no campo da Internet e na sua utilização pelos receptores. O caminho da inclusão e integração comunicacional passará pela transformação dessas mensagens e por projetos e ações a serem desenvolvidos na construção dos sites na Internet.

Surveying sexualities: Internet research with non-heterosexuals

In this article we describe and evaluate the process of conducting online survey research about the legal recognition of same-sex relationships (key findings from which we have reported elsewhere, see Harding and Peel, 2006). Our aim in so doing is to contribute to the growing generic literature on internet-based research methods (Nosek et al., 2002; Rhodes et al., 2003; Stern, 2003; Strickland et al., 2003; Thomas et al., 2000) to the research methods literature within lesbian, gay, bisexual, trans and queer (LGBTQ) psychologies (Fish, 2000; Morris and Rothblum, 1999; Meezan and Martin, 2003; Mustanski, 2001) and also to extend the germinal literature focusing on internet research with non-heterosexual groups (Elford et al., 2004; Ellis et al., 2003; Ross et al., 2000). We begin by discussing the process of developing the online survey tool, before outlining the experience of the survey ‘going live’ and providing details of who completed the survey. We conclude by exploring some of the positives and pitfalls of this type of research methodology.

Internet technologies, ECRM capabilities, and performance benefits for SMEs:An exploratory study

Research on large firms suggests that dedicated customer relationship management (CRM) software applications play a critical role in creating and sustaining customer relationships. CRM is also of strategic importance to small and medium-sized enterprises (SMEs), but most of them do not employ dedicated CRM software. Instead they use generic Internet-based technologies to manage customer relationships with electronic CRM (eCRM). There has been little research on the extent to which the use of generic Internet technologies contributes to SME performance. The present study fills the gap, building upon the literature on organizational capabilities, marketing, and SMEs to develop a research model with which to explore the relationships between generic Internet technologies, eCRM capabilities, and the resulting performance benefits in the SME context. A survey across 286 SMEs in Ireland finds strong empirical evidence in support of the hypotheses regarding these benefits. The study contributes to managerial decision making by showing how SMEs can use generic Internet technologies to advance their customer relationships and contributes to theory development by conceptualizing eCRM capabilities in an SME context.

Progress toward 100-G digital coherent pluggables using InP-based photonics

A new generation of high-capacity WDM systems with extremely robust performance has been enabled by coherent transmission and digital signal processing. To facilitate widespread deployment of this technology, particularly in the metro space, new photonic components and subsystems are being developed to support cost-effective, compact, and scalable transceivers. We briefly review the recent progress in InP-based photonic components, and report numerical simulation results of an InP-based transceiver comprising a dual-polarization I/Q modulator and a commercial DSP ASIC. Predicted performance penalties due to the nonlinear response, lower bandwidth, and finite extinction ratio of these transceivers are less than 1 and 2 dB for 100-G PM-QPSK and 200-G PM-16QAM, respectively. Using the well-established Gaussian-Noise model, estimated system reach of 100-G PM-QPSK is greater than 600 km for typical ROADM-based metro-regional systems with internode losses up to 20 dB. © 1983-2012 IEEE.

Ellátási lánc kapcsolatok modellezése = Modeling of supply chain relationships

A dolgozatban az ellátási láncokban meglévő diadikus kapcsolatok minőségét állítjuk a vizsgálatok középpontjába. Az irodalomban számtalan megközelítés ismert az ellátási lánc kapcsolatok fejlődésének leírására. Ezen fejlődési elméletek inkább elméleti szinten írják le a diadikus kapcsolatok változását, annak empirikus tesztelhetőségét nem vizsgálják. Dolgozatunkban kísérletet teszünk az ellátási lánc kapcsolatok fejlődésének empirikus vizsgálatára. Arra próbálunk választ találni, hogy az életciklus hipotézis az üzleti kapcsolatok időbeli fejlődésére alkalmazható-e. = Our paper combines two approaches using data of an internet based questionnaire and applying quantitative analysis it tests the hypothesis business relationship development in time can be described with the concept of life cycle. The concept of life cycle is widely used in business research. Among others the diffusion of innovation is described using this concept, or the concept of product life cycle just to name a few. All of these researches analyze the life cycle along a specific variable (for example the volume of sales or revenue in case of the product life cycle) which (except the last stage of the cycle, the decline) has a cumulative character resulting in the widely known specific shape of a life cycle. Consequently testing a life cycle hypothesis inevitably means the acceptance of some type cumulativity in the development.

The Use of the Internet in the U.S Lodging Industry

The internet has been heralded as the communications and marketing tool of the future for the hospitality industry. Both corporate executives and information technology experts feel the hotel of the future cannot do without a presence on the Web. Yet, do the actions of hospitality operators in the field reflect this optimism? This article reports on a study done among property managers in the U.S. lodging industry to determine the actual use of the internet in hotel properties of various types and sizes. Additionally, it addresses development and maintenance issues related to internet use.

The first time delivery of the first link learning series using Skype and YouTube

Introduction: This case study documented the experiences of informal and service providers who participated in the first time delivery of the First Link Learning Series from May–August 2013 in Newfoundland and Labrador. The aim of this study was to understand how informal caregivers of people with dementia experience this Internet mediated health resource, and how Skype and YouTube can be used as tools for the Alzheimer Society of Newfoundland and Labrador to effectively deliver the First Link Learning Series. Methods: Sources of data included key informant interviews (n=3), pre- study and post-study interviews with informal dementia caregivers (n=2), institutional documentation, field notes, and YouTube analytics. Framework Analysis was used to make meaning of the qualitative data, and descriptive statistics were used to report on quantitative outcomes. Findings: Between 3% and 17% of registered First Link clients attended the learning series sessions, however only two caregivers participated using Skype or YouTube. Framework Analysis revealed three shared themes: access, connection and privacy. Discussion: The themes helped to begin building theory about barriers and facilitators to Internet mediated health resources for informal dementia caregivers. Experiences of service providers using the Internet to support clients served to begin building a case for the appropriateness of these media. A modified version of Dansky et al.’s (2006) theoretical framework for evaluating E-Health research that situates the person/user in the model, helped guide discussion and propose future directions for the study of Internet based health resources for informal dementia caregivers.

Guiding public protest: assessing the propaganda model of China’s hybrid newspaper industry

This dissertation presents an account and analysis of published mainland Chinese media coverage surrounding three major events of public protest during the Hu-Wen era (2003-2013). The research makes a qualitative analysis of printed material drawn from a range of news outlets, differentiated by their specific political and commercial affiliations. The goal of the research is to better understand the role of mainstream media in social conflict resolution, a hitherto under-studied area, and to identify gradations within the ostensibly monolithic mainland Chinese media on issues of political sensitivity. China’s modern media formation displays certain characteristics of Anglophone media at its hyper-commercialised, populist core. However, the Chinese state retains an explicit, though often ambiguous, remit to engage with news production. Because of this, Chinese newspapers are often assumed to be one-dimensional propaganda ‘tools’ and, accordingly, easily dismissed from analyses of public protest. This research finds that, in an area where political actors have rescinded their monopoly on communicative power, a result of both policy decisions and the rise of Internet-based media platforms, established purveyors of news have acquired greater latitude to report on hitherto sensitive episodes of conflict but do so under the burden of having to correctly guide public opinion. The thesis examines the discursive resources that are deployed in this task, as well as reporting patterns which are suggestive of a new propaganda approach to handling social conflict within public media. Beside the explicitly political nature of coverage of protest events, the study sheds lights on gradations within China’s complex, hybrid media landscape both in terms of institutional purpose and qualitative performance.

Cooperative or collaborative learning: Is there a difference in university students’ perceptions?

The hypothesis that the same educational objective, raised as cooperative or collaborative learning in university teaching does not affect students’ perceptions of the learning model, leads this study. It analyses the reflections of two students groups of engineering that shared the same educational goals implemented through two different methodological active learning strategies: Simulation as cooperative learning strategy and Problem-based Learning as a collaborative one. The different number of participants per group (eighty-five and sixty-five, respectively) as well as the use of two active learning strategies, either collaborative or cooperative, did not show differences in the results from a qualitative perspective.

Achieving Energy Saving through Proxying Applications on behalf of Idle Devices

Several studies in the past have revealed that network end user devices are left powered up 24/7 even when idle just for the sake of maintaining Internet connectivity. Network devices normally support low power states but are kept inactive due to their inability to maintain network connectivity. The Network Connectivity Proxy (NCP) has recently been proposed as an effective mechanism to impersonate network connectivity on behalf of high power devices and enable them to sleep when idle without losing network presence. The NCP can efficiently proxy basic networking protocol, however, proxying of Internet based applications have no absolute solution due to dynamic and non-predictable nature of the packets they are sending and receiving periodically. This paper proposes an approach for proxying Internet based applications and presents the basic software architectures and capabilities. Further, this paper also practically evaluates the proposed framework and analyzes expected energy savings achievable under-different realistic conditions.

Sustainable Business Models – What Do Management Theories Say?

Literature describing the notion and practice of business models has grown considerably over the last few years. Innovative business models appear in every sector of the economy challenging traditional ways of creating and capturing value. However, research describing the theoretical foundations of the field is scarce and many questions still remain. This article examines business models promoting various aspects of sustainable development and tests the explanatory power of two theoretical approaches, namely the resource based view of the firm and transaction cost theory regarding their emergence and successful market performance. Through the examples of industrial ecology and the sharing economy the author shows that a sharp reduction of transaction costs (e.g. in the form of internet based systems) coupled with resources widely available but not utilised before may result in fast growing new markets. This research also provides evidence regarding the notion that these two theoretical approaches can complement each other in explaining corporate behaviour.
