Self Presentation in Blogs and Social Networks
Authors: Brivio Eleonora  , Cilento Ibarra Francesca
Published: February 2025

Recent approaches to the study of identity in online contexts underline how people on the Internet have multiple identities and are at risk of identity fragmentation. Subjectivities are context-specific, negotiated with other people and actualized in Self Presentations. The aim of this study is to investigate how social media users deal with choices regarding their Self Presentation and how different profiles of the same person relate to one other. Thirty-six users with accounts on two blog-hosting services and one social network website answered an online structured interview and elaborated on the different choices of Self Presentation for each service. Content Results show users accurately and consciously choose the way they present their Self according to their aims, actual and potential readership, and the technical possibilities of the media. Answers also show that people online are conscious of the multiple presentations they enact, and they feel an underlining sense of unity and coherence, which may be traced back to the concept of Self.

Authors: Cárdenas Georgina  , Botella Cristina  , Quero Soledad  , Moreyra Liliana  , De La Rosa Anabel  , Muñoz Sandra
Published: February 2025

Anxiety as a symptom or disorder is affected by multiple variables such as antecedent events, interpretation of the events, psychological vulnerability, and individual differences in the reaction towards an event. Nowadays, virtual-reality therapy is used as therapeutic tool for patients suffering from some kind of anxiety disorder. In Mexico, the National Survey on Psychiatric Epidemiology [1] informed that anxiety disorders are the most common disorders followed by affective disorders, which are more prevalent in women than in men. Among the different anxiety disorders, the category of specific phobias (7.1%) was the most common. Based on this demand, a collaborative effort between research groups from the University Jaume I in Spain and the National Autonomous University of Mexico (UNAM), initiated a project which purpose was the technological transfer of systems based on virtual reality for the treatment of Fear of Flying to be implemented and evaluated in the Mexican population. The treatment protocol developed by Botella et al., [2] has been applied to five volunteer participants. In this paper we present data of adapted treatment protocols in Mexican population that support the efficacy of VR of treatment of fear of flying, achieved by the Spanish research group.

Authors: Chua Hannah Faye  , Polk Thad  , Welsh Robert  , Liberzon Israel  , Strecher Victor
Published: February 2025

An increasing number of smokers are obtaining information from the web to help them quit smoking. In this study, we examined how smokers process different types of messages similar to those from a web-based smoking cessation program: personalization/feedback (“Jane, you are a 23-year old female smoker”), motivational (“If you quit smoking, you could save $1200 a year”), and instructional (“When you feel angry, talk to someone instead of smoking”) messages. Using functional magnetic resonance imaging, smokers were exposed to the messages. On a later session, participants completed an online tailored smoking cessation program and started on a 10-week course of nicotine patch. Results show that participants indeed process the messages differently, activating brain regions associated with self-related processing (personalization/feedback), anticipated reward processing (motivational messages) and rules processing (instructional messages). This research is relevant for advancing web-based tailored interventions for substance use.
Mixed Reality for PTSD/TBI Assessment
Authors: Fidopiastis Cali  , Hughes Charles E.  , Smith Eileen
Published: February 2025

Mixed Reality (MR) refers to the blending of virtual content into the real world. Using MR, we create contextually meaningful scenarios in which users carry out tasks encountered in the presence of visual and aural distracters. Visual distracters can include subtle ones – people walking; and more abrupt ones – cartons falling. Aural distracters can include gentle ones – fans whirring; and more aggressive ones – automobiles backfiring. The intensity of these distracters can be dynamically controlled by a therapist or software that takes into account the patient's perceived level of stress. Intensity can also be controlled between experiences. For example, one may increase the stress level in a subsequent session, attempting to improve a person's tolerance. Assessment of progress includes psychophysical metrics (stress indicators) and the performance of tasks (accuracy and adherence to time constraints). By accurately capturing a patient's interaction with the environment in the context of simulation events, we can use MR as a tool for assessment and rehabilitation planning for individuals with stress-related injuries. This paper reports on the MR environment we have developed and its efficacy (realized and potential) for the assessment of post-traumatic stress disorder (PTSD) with or without traumatic brain injury (TBI).

Authors: Kenny Patrick G.  , Parsons Thomas D.  , Rothbaum Barbara  , Difede Joann  , Reger Greg  , Rizzo Albert
Published: February 2025

Adequate treatment of PTSD is a growing concern for the military. However, there is a shortage of qualified personnel available to apply this treatment. Virtual patient systems offer a novel technology to enhance the training needs of such health providers. This pilot project builds on previous work done with virtual patients and describes a novel scenario wherein a virtual patient is immersed within an exposure therapy simulation while a clinician interacts and guides the virtual patient through the recovery process using exposure therapy for PTSD. While this work is ongoing, preliminary results will be presented.
Advances in Wearable Technology for Rehabilitation
Authors: Bonato Paolo
Published: February 2025

Assessing the impact of rehabilitation interventions on the real life of individuals is a key element of the decision-making process required to choose a rehabilitation strategy. In the past, therapists and physicians inferred the effectiveness of a given rehabilitation approach from observations performed in a clinical setting and self-reports by patients. Recent developments in wearable technology have provided tools to complement the information gathered by rehabilitation personnel via patient's direct observation and via interviews and questionnaires. A new generation of wearable sensors and systems has emerged that allows clinicians to gather measures in the home and community settings that capture patients' activity level and exercise compliance, the effectiveness of pharmacological interventions, and the ability of patients to perform efficiently specific motor tasks. Available unobtrusive sensors allow clinical personnel to monitor patients' movement and physiological data such as heart rate, respiratory rate, and oxygen saturation. Cell phone technology and the widespread access to the Internet provide means to implement systems designed to remotely monitor patients' status and optimize interventions based on individual responses to different rehabilitation approaches. This chapter summarizes recent advances in the field of wearable technology and presents examples of application of this technology in rehabilitation.
Why Is Music Effective in Rehabilitation?
Authors: Antonietti Alessandro
Published: February 2025

In this chapter a conceptual foundation of employing music in rehabilitation is highlighted. The basic assumption is that, when a person is involved in performing or listening to music, she has a comprehensive experience in which several mental registers are activated simultaneously. The specific effect of music is to trigger a coordinated action of motor, visuospatial and verbal mechanisms. Thanks to the synergic activation of these mechanisms, music can stimulate, support and driven the mental functions to be rehabilitated.
Project HealthDesign: Enhancing Action through Information
Authors: Brennan Patricia Flatley  , Casper Gail  , Downs Stephen  , Aulahk Veenu
Published: February 2025

Project HealthDesign is a country-wide initiative in the United States designed to stimulate innovation in personal health records (PHRs). Nine grantee teams engaged in an 18-month long design and prototyping process. Two teams addressed the needs of children and adolescents; three created novel approaches to help adults prevent or manage metabolic syndrome; three groups employed interface innovations to assist patients with chronic care management and one team devised a novel calendaring system to assist patients undergoing complex medical/surgical treatments to integrate care processes into their daily lives. These projects not only included development and testing of novel personal health records applications, but also served as the starting point to specify and implement a common technical core platform. The project advanced PHR development in two key ways: intensive user-centered design and a development architecture that separates applications of PHRs from the infrastructure that supports them. The initiative also allowed systematic investigation of significant ethical, legal and social issues, including how privacy considerations are changed when information technology innovations are used in the home and the rebalancing of the authority structure of health care decision making when patient-centered approaches guide the design of PHRs.

Published: February 2025

This qualitative study was part of the pre-implementation formative evaluation of SelectHealth's Continuity of Care Record (CCR), an electronic health information network (EHI) for HIV/AIDS care in New York City (NYC). The purpose of the study was to explore case managers' perceptions of the barriers to adoption of the CCR. Focus group methodology was used to gather perceptions from 26 participants who provided direct case management services for persons living with HIV/AIDS (PLWHA) in NYC. Question development was guided by models of technology acceptance. Data about the barriers to implementation of the system were classified into four main themes: client capacity for system adoption, potential breech of confidentiality, information quality concerns, and training needs. The four identified themes can serve as focal points for developers seeking to create EHI networks for the provision of HIV care.

IMIA-NI's past achievements are reflected upon in the context of its current strategic directions. Two key historical milestones are described in some detail, the ISO Reference terminology model for nursing and the International Nursing Minimum Data Set development project, as this work is continuing to influence future directions in health and nursing informatics. Current features of our health care environment are explored noting the current desire of most nations to implement electronic health records (EHRs) and its relationship with IMIA-NI's strategic directions. Nurses can play their part by working collaboratively, converting their knowledge into computer processable formats, establishing the necessary professional knowledge governance infrastructure and lobbying key decision makers to establish national infrastructures that will enable the adoption and optimum use of EHRs.
Oulu Patient Classification Instrument within Primary Health Care
Authors: Frilund Marianne  , Fagerström Lisbeth
Published: February 2025

As patients have become older their care needs have increased, and this has consequences for the working conditions within primary health care. Objectives: The aim of this study was to evaluate, whether the OPC instrument, which has been developed for hospital care, is valid and useful within primary healthcare for older people. Materials and Methods: Reliability and validity testing of the OPC instrument was carried out at a health care centre in Eastern Finland spring 2004. A total number of 92 questionnaires were handed out, and the response rate was 67% (n=61) in order to test the validity. The inter-rater reliability was tested through parallel classification. A total number of 860 patient's were classified; in total 1722 classifications ware done. Cohens Kappa was chosen as the measurement for the consensus between the nurses' classification. Resultat: The consensus of the NI scores in total (OPC points) was 71%. The consensus measured with Kappa (k) showed a strong (0.65) consensus degree. Discussion: It can be said that the OPC instrument achieved a high enough reliability and validity in order to be seen as a reliable and useful instrument to measure the NCI within primary healthcare for the elderly. Conclusion: The OPC instrument can be seen as providing a fairly comprehensive view of the patient's caring needs, without claiming to be covering everything.
Towards a Standardized Representation to Support Data Reuse: Representing the ICNP Semantics Using the HL7 RIM
Authors: Kim Hyeoneui  , Dykes Patricia  , Mar Perry  , Goldsmith Denise  , Choi Jeeyae  , Goldberg Howard
Published: February 2025

Representing nursing assessment data in a reusable manner is important as it provides a basis for decision making in patient care. In a previous study, we have extended the ICNP concept model to support representation of nursing assessment data. In this study, we evaluated its potential to support electronic documentation of nursing assessment data and HL7 conformant message generation by mapping it to the HL7 RIM. The semantics represented by the ICNP were completely related to the RIM implying that the ICNP is a good candidate terminology to encode the data with in an electronic documentation system. A few differences between the two models in representing the same semantics suggests that there is value to supporting broad ranges of semantic relations in the ICNP.

Authors: Tsuru Satoko  , Iizuka Yoshinori  , Munechika Masahiko
Published: February 2025

Quality assurance has become key concerns in healthcare and it is important to standardize the processes for healthcare properly. Though it was needed to describe process of healthcare diagnosis and treatment, it was very difficult by the reason of being service products including complexity and expertise. We challenged to visible, structurize, standardize and IT-systematize of clinical knowledge for healthcare quality management. The patient condition adaptive path system (PCAPS) was developed. PCAPS describes an overall flow of possible clinical pathways that a patient's disease state may trace and detailed medical judgment and treatments for each disease state. It suggests possibility of quality assurance using the standard plan of medical treatment process. PCAPS comprises two major tools: clinical process chart and unit sheet. These describe the total flow of treatment and the concrete medical treatments involved in each step. The PCAPS master is proposed. This is a glossary of the terms that are used in the unit sheet. Each master file has special structure for each work domain. In other words, PCAPS describes the standard process of healthcare using the clinical process chart, unit sheet, and PCAPS master. We apply nursing master file for nursing care action and observation offered by MEDIS-DC in Japan. Through we developed many PCAPS contents, we identified description of structured nursing knowledge. The nursing master file was brushed up by designing PCAPS content using it. It was suggested that PCAPS contents as standard clinical plan designed by medical specialist team included nursing knowledge.
Moving to a Culture of Nurse as Knowledge Worker and a New Way of Knowing in Nursing
Authors: Nagle Lynn M.  , Yetman Linda
Published: February 2025

In this paper, the authors speculate on the future of nursing practice as it will be informed by emerging technologies for the management of clinical information and knowledge and the generation of new understandings. It is postulated that without a concomitant effort to transform nursing practice, the fulsome benefits of electronic health records and associated tools will not be realized for nurses, other clinicians and patients. The path to creating a nursing practice culture of integrated knowledge management necessitates new thinking about clinical care delivery and an expansion of the ways of knowing in nursing. For the purpose of this paper, clinical practice transformation is defined as: moving beyond the form and function of nursing practice as we know it today by boldly advancing the redesign of clinical processes and being open to emerging transformative possibilities within society and healthcare through the use of technology.

Using Personas and Prototypes to Define Nurses' Requirements for a Novel Patient Monitoring Display
Authors: Koch Sven  , Sheeren Amanda  , Staggers Nancy
Published: February 2025

Software is often designed based on the designer's mental model rather than the user's. To correct this, we created personas (archetypes) of nurses using observations and semi-structured interviews. We developed and evaluated patient monitoring display prototypes for each persona. Among 11 ICU nurses, we found that the majority of nurses preferred a parsimonious data representation with large numbers and waveforms allowing all relevant data to be visible. Using personas and paper prototypes is an inexpensive and effective way to assess nurses' requirements and design preferences.

Preserving consent-for-consent with feasibility-assessment and recruitment in clinical studies: FARSITE architecture
Authors: Ainsworth John  , Buchan Iain
Published: February 2025

Best practice guidance for clinical studies asks investigators to employ the highest possible standards in privacy and consent. When considering the feasibility of a clinical study, issues of privacy extend not only to actual but also to potential study participants. The consent required to access records to determine whether or not an individual might be eligible to participate in a study is sometimes referred to as consent-for-consent. Some initiatives to enhance the efficiency of study-recruitment could compromise consent-for-consent, for example by inviting a patient to take part in a study without the knowledge of their attending clinician. Through iterative working with experts and examination of protocols we explored a range of scenarios for assessing the feasibility of clinical trials and observational studies, and recruiting participants. The main requirement we identified was to speed up feasibility-assessment and recruitment while preserving the patient-clinician trust relationship that is central to consent-for-consent. We present an appropriate information system architecture, FARSITE (Feasibility Assessment and Recruitment System for Improving Trial Efficiency), and show in principle that faster recruitment into clinical studies need not compromise best practice in privacy or consent. We show that FARSITE is a specific instance of an ‘e-Lab’ architecture for assembling data, methods and expertise around study protocols and defined populations.

Published: February 2025

Production exploitation of cardiac image analysis tools is hampered by the lack of proper IT infrastructure in health institutions, the non trivial integration of heterogeneous codes in coherent analysis procedures, and the need to achieve complete automation of these methods. HealthGrids are promising technologies to address these difficulties. This paper details how they can be complemented by high level problem solving environments such as workflow managers to improve the performance of applications both in terms of execution time and robustness of results. Two of the most important important cardiac image analysis tasks are considered, namely myocardium segmentation and motion estimation in a 4D sequence. Results are shown on the corresponding pipelines, using two different execution environments on the EGEE grid production infrastructure.

Investigation of some anisotropic characteristics of Bangkok Clay
Authors: Yimsiri S.  , Ratananikom W.  , Likitlersuang S.
Published: February 2025

Some anisotropic properties of Bangkok Clay are investigated in the laboratory using advanced triaxial apparatus and in the field by self-boring pressuremeter. The triaxial apparatus incorporates local axial & radial strain measurement systems and bender element system. Isotropically consolidated undrained triaxial compression tests are performed on both vertically- and horizontally-cut undisturbed specimens. The anisotropic characteristics of interest are (i) deformation during isotropic consolidation, (ii) small-strain shear modulus, and (iii) modulus during undrained compression shearing. The observed behaviors are compared with other published data from bender element, triaxial, and seismic cone penetration tests. The anisotropic characteristics of Bangkok Clay, which is lightly-overconsolidated clay, are compared with those of London Clay, which is heavily-overconsolidated clay, and some discussions are addressed.
Assessment of the skin friction of large diameter bored piles in sand
Authors: El-Nahhas F.M.  , El-Mossallamy Y.M.  , Tawfik M.M.
Published: February 2025

Large diameter bored piles currently represent a major element of deep foundations that can successfully be utilized in different subsurface conditions. However, there is an apparent difficulty in correlating the skin friction and end bearing resistances of such piles with the results of in-situ tests with adequate accuracy. Hence, the need for further research associated with the estimation of the ultimate capacity and load-settlement behavior of large diameter bored piles based on these tests is evident. This paper will focus on the assessment of skin friction of large diameter bored piles in cohesionless soil using correlation with in-situ tests such as standard penetration test (SPT). Traditionally, average SPT blow counts have been used, which invariably involves various degrees of uncertainty. This uncertainty can be attributed to several factors, such as soil spatial variability, effect of construction technique, and model uncertainty. Engineering judgment and reliance on appropriate factors of safety have been the conventional tools adopted in the geotechnical engineering practice to deal with the uncertainty associated with pile design. There is a need, however, to develop theoretically-sound methods to account for the uncertainty in SPT-based pile design especially for large diameter bored piles where pile settlement becomes of significant importance. In this paper, an attempt is made to develop a new SPT-based correlation with the maximum skin friction capacity of large diameter bored piles, in sand, that takes into account the effect of various sources of uncertainty.

There are interesting debates among the geotechnical engineers involved in the design and construction of earth dams, regarding the technical and practical advantages and disadvantages of using mixed soils (such as SC or GC) versus clayey soils (such as CL or CH) as materials for the dams core. Mixed soils are usually mixtures of clay and sand and (or) gravel. This paper presents the results of a series of numerical analyses carried out on a hypothetical earth dam with a vertical core and with two different types of materials: (i) pure clay and (ii) mixed clay. Regarding the consolidation conditions within the core during the dam construction, two types of analyses are performed: (a) fully undrained and (b) partially drained conditions. The results of the analyses show that for fully undrained analyses, excess pore water pressures developed within the core during construction are comparatively higher when the core comprises the pure clay. For the partially drained analyses, the values of excess pore water pressures in the two types of cores depend on the construction and consolidation rate. Settlements in the core consisting of the pure clay are comparatively higher if drainage of the core is impeded. When consolidation of the core is permitted, the settlements of the core comprising of the pure clay and the mixed clay are not much different. Horizontal displacement values of the core consisted of the pure clay material are higher than their corresponding values of the core consisted of the mixed clay.

This study analyzed the behavior of geotextile tube structure which was constructed in Incheon Bridge construction site. In a single tube structure as an internal stability, the displacement and tensile strength of constructed tube indicated that the largest value was occurred at the surface of circumferential direction. The vertical pressure is contributed to the equivalent pressure in the 1st layer, however, when the upper load is increased, the pressure was concentrated on the center of tube structure and then it makes the differential settlement on the ground. The axial strain of geotextile tube is the largest between two geotextile tubes in the 1st layer.

Geotechnical design is, perhaps, the civil engineering subject most dominated by uncertainty. Although partly due to limited field investigations, the main reason of this uncertainty is the highly heterogeneous and anisotropic nature of ground materials. Deterministic design methods as required by design codes, attempt to account for ground uncertainty by adopting conservative values of ground parameters and relatively large safety factors. This paper performs probabilistic analyses of soil slopes using Monte Carlo simulation in order to investigate the effect of these assumptions on the calculated probability of failure of the slopes. For slopes in saturated cohesive materials under undrained conditions an analytical solution is proposed while for drained conditions parametric analyses are performed. It is shown that slopes designed according to Eurocode 7 (EN1997-1) correspond to probabilities of failure up to 12%. Based on the results of these analyses, diagrams are proposed for the estimation of the probability of failure as a function of the geometrical, geotechnical and support parameters of the slope.
Deep Excavations in Glacial Tills in Dublin

Published: February 2025

A number of Deep Excavations up to 23m in depth have recently been completed in Dublin. Different approaches including propped and unpropped, Secant and Contiguous Pile Wall Solutions have been employed on various projects. The paper updates a database for propped and cantilevered wall supported excavations in Glacial Tills. A comment and interpretation of recorded wall movement versus retained heights and wall stiffness is provided. Modelled predications are also discussed. Two case histories of deep basement excavations including Spencer Dock in the Docklands, 14m excavation at Westgate (Heuston Square) and other projects are presented and discussed.
Lightweight mixture using sand, EPS-beads and cement
Authors: Abdelrahman G.E.
Published: February 2025

A laboratory study is presented in this paper on the formation of a lightweight material for embankment on weak soils. The proposed material is made by blending sandy soil with (Expanded Poly-Styrene) EPS-beads and a stabilizing material such as cement. The effect of different compositions and different ratios between EPS-beads, and cement with sand on the maximum dry density, optimum moisture content, ultimate shear stress and angle of internal friction of the lightweight mixture are studied. It is observed that the density of the lightweight mixture can be effectively controlled by the amount and density of EPS-beads used. With the inclusion of 0.3 - 3 % of EPS-beads (to sand by weight), the bulk density of the lightweight mixture formed can be reduced to 8.5-18 kN/m3. The shear strength and stiffness of the lightweight mixture can be controlled by adjusting the amount of cement used. The angle of shearing resistance of the lightweight mixture increases considerably if cement to soil ratio of 3-10% is used. With adding cement to EPS-beads and sand mixture, higher dry density and less optimum moisture content are obtained.

Le dépôt de phosphogypse à Sfax (Tunisie) constitue un danger permanent pour l'environnement marin et terrestre. Le projet Taparura consiste en partie de confiner ce dépôt pour limiter partiellement ou totalement la pollution par les métaux lourds par la réalisation d'un écran étanche en bentonite ciment. Cette étude propose une méthodologie de formulation des coulis en bentonite ciment. Les propriétés physiques à l'état frais et les propriétés mécaniques à l'état durcis du matériau ont été déterminées. L'étude comporte essentiellement deux volets : le premier concerne une synthèse bibliographique d'une part sur les matériaux de composition, bentonite et ciment, et leurs propriétés et d'autre part sur les méthodes de formulation et les essais appropriés normalisés pour la caractérisation des coulis Le second volet est relatif à une étude expérimentale effectuée en vue de proposer une composition optimale du matériau : bentonite ciment.
Engineering assessment of jet-grouted structures

The treatment characteristics, quality control measures and outcomes of two different jet-grout based soil treatments are described in detail. In the first one, a jet-grouted slab was built to limit retaining wall movements in a cut-and-cover tunnel. Quality control relied on borehole core quality assessment and laboratory testing. Core quality was very sensitive to coring practices. The strength and stiffness of the jet-grouted slab were deemed adequate and the structure successfully contributed to minimal wall movements. In the second case, a jet-grouted treatment was designed to provide strengthening and impermeabilization around a tunnel excavated on silty sands below the water table and underneath another tunnel. Control was based on extensive coring, cross-hole seismic surveys and permeability tests. The results were generally favourable and where defects were detected, reparation was undertaken. However, in spite of all those actions, a number of deficiencies escaped detection and only became apparent during the excavation of the tunnel resulting in significant construction problems.
The main principles of tunneling under compressed air
Authors: Placzek D.
Published: February 2025

Tunneling in soil under the groundwater-level requires the sure removal of groundwater under construction. Different methods are available and they have proved in practice. There is to differentiate between the sealing, lowering and the squeezing of groundwater. While the sealing and the lowering of the groundwater have to anticipate the tunneling , it is necessary to squeeze the groundwater under construction. Standard solutions for groundwater-squeezing are the application for the support of the heading face by fluid or air pressure.
