Kinds of Phone Terms modified by Phone Selected AbstractsConfigurations of Relationships in Different Media: FtF, Email, Instant Messenger, Mobile Phone, and SMSJOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 4 2007Hyo Kim This study analyzes the configurations of communication relationships in Korea through face-to-face, email, instant messaging, mobile phone, and short message service media. Through a web survey, we asked respondents to identify (1) for each of the five media (2) up to five of their most frequent communication partners, (3) the partner's social role (including colleagues, family, friends), and (4) their own employment category. Individual-level and network-level analyses were used to compare variations in communication relationships and configurations of relationships among social roles overall, within each medium, and for different employment categories, and to identify configurations of relationships across media. IM, SMS, and mobile phone are distinctive media for students, mobile phone for homeworkers, and email for organizational workers. Moreover, mobile phones tend to be used in reinforcing strong social ties, and text-based CMC media tend to be used in expanding relationships with weak ties. Finally, face-to-face (FtF) seems to be a universal medium without significant differences across respondents' employment categories. [source] EFFECTS OF BARLEY STRAW EXTRACT ON GROWTH OF FIVE SPECIES OF PLANKTONIC ALGAEJOURNAL OF PHYCOLOGY, Issue 2001Article first published online: 24 SEP 200 Holz, J. C.1, Fessler, C. J.2, Severn, A. A.1 & Hoagland, K. D.1 1School of Natural Resource Sciences, University of Nebraska, 103 Plant Industry Bldg., Lincoln, NE, 68583-0814; 2Biology Department, Nebraska Wesleyan University, 5000 St. Paul Ave., Lincoln, NE, 68504; Phone: 402-472-6648; Fax: 402-472-2964 The effects of exposure to barley straw extract and the timing of exposure on the growth of four common cyanophyte species and one species of green algae were investigated in two laboratory experiments. Clonal cultures of Anabaena cylindrica, Cylindrospermum sp., Gloeocapsa sp., Eucapsis sp., and Chlorella vulgaris were obtained from culture collections. In both experiments, the algae were cultured in Guillard's WC medium at 20 °C on a 12:12 L/D photoperiod. In the first experiment, the algae were dosed with four concentrations of barley straw extract at the beginning of the experiment (day 0) and growth was monitored every second day using fluorometric detection of chlorophyll a for 14 d. In the second experiment, the algae were dosed with the same extract concentrations, but the extract was not added until the algae were in exponential growth phase (day 6). Both experiments also had control treatments (i.e. no extract) and each extract and control treatment was replicated five times. Growth of C. vulgaris was inhibited by all doses in both experiments, but inhibition was 22% greater when the extract was added on day 0. Growth Gleocapsa sp. was slightly inhibited by all doses when the extract was added on day 0, but not when it was added on day 6. No other species were inhibited, regardless of dose or timing of dose. The results of this study and other bioassay studies suggest that differential susceptibility to barley straw among algae is common and may reduce the effectiveness of barley straw as an algal control technique. [source] The role of impulsivity in actual and problematic use of the mobile phoneAPPLIED COGNITIVE PSYCHOLOGY, Issue 9 2008Joël Billieux Several authors have investigated the risks arising from the growth in mobile phone use (e.g. debts incurred by young people). The aims of the present study are (1) to validate a new questionnaire assessing problematic mobile phone use: the Problematic Mobile Phone Use Questionnaire (PMPUQ), and (2) to investigate the relationships between the PMPUQ and the multi-faceted construct of impulsivity. With these aims, 339 subjects were screened using the PMPUQ and the UPPS Impulsive Behaviour Scale (UPPS) which assesses four distinct components associated with impulsive behaviours (urgency, lack of premeditation, lack of perseverance and sensation seeking). The results showed that the PMPUQ has an acceptable fit and assesses four different dimensions of problematic mobile phone use (prohibited use, dangerous use, dependence, financial problems). While each facet of impulsivity played a specific role in mobile phones use, urgency appeared to be the strongest predictor of problematic use. Copyright © 2008 John Wiley & Sons, Ltd.

We assessed this method and compared impairment of performance due to alcohol in everyday life with measurements made in the laboratory. Methods:, Thirty-eight volunteers (20 male, aged 18,54 years) took part in the everyday study, completing assessments twice a day for 14 days following requests sent by text messages to the mobile phone. Twenty-six of them (12 male, aged 19,54) took part in a subsequent two-period crossover lab study comparing alcohol with no alcohol (placebo). Results:, Everyday entries with 5 or more units of alcohol consumed in the past 6 hours (inferred mean blood alcohol concentration 95 ml/100 ml) showed higher scores for errors in tests of attention and working memory compared with entries with no alcohol consumed that day. Response times were impaired for only 1 test, sustained attention to response. The laboratory comparison of alcohol (mean blood alcohol concentration 124 mg/100 ml) with placebo showed impairment to both reaction time and error scores for all tests. A similar degree of subjective drunkenness was reported in both settings. Conclusions:, We found that mobile phones allowed practical research on cognitive performance in an everyday life setting. Alcohol impaired function in both laboratory and everyday life settings at relevant doses of alcohol.

[source] Follow-Up of 1 mg Finasteride Treatment of Male Pattern Baldness,Difference between Clinical Trials and Private Office Follow-Up: Influences on Prescribing Habits EvaluatedDERMATOLOGIC SURGERY, Issue 5 2004Marvin J. Rapaport MD Background. Finasteride (Propecia) was approved by the FDA in 1998 for treating men with androgenetic alopecia. The published clinical trials demonstrated statistical differences between drug and placebo. Rarely do new drugs undergo further non-drug-company-sponsored studies of efficacy. Concerns about clinical studies and marketing of drugs prompted this evaluation of a large group of patients taking this medication. Objective. Finasteride usage offered an opportunity not only to understand the acceptance of a cosmetically oriented medication, but also to evaluate subjective comments and compliance after a long period of time. Methods. A total of 1261 patients were monitored with phone calls every 3 months after finasteride was initially prescribed. After 12 months, a detailed questionnaire was sent to all patients with an additional letter and two telephone calls if no response was received. Statistical analysis of the patients' data was made. Results. Thirty-two percent or 414 men continued to take finasteride daily for 1 to 3 years. Twenty-four percent or 297 men discontinued the drug between 3 and 15 months owing to poor results. The remaining 44% or 549 men were lost to follow-up despite numerous attempts to contact them. Conclusion. A total of 414 men continued to take the medication, but only 211 returned detailed questionnaires. A small percentage of this group felt that they grew hair. The remaining patients noted poor results.

[source] Perceived need for emergency medicine training in Pakistan: A survey of medical education leadershipEMERGENCY MEDICINE AUSTRALASIA, Issue 2 2009Junaid A Razzak Abstract Objective: To assess the perception of leaders of the academic medical institutions regarding the need for specialty training in emergency medicine. Methods: A cross-sectional survey was conducted in all medical colleges of Pakistan in September 2005. Our sample included all academic leaders of recognized medical colleges in Pakistan. A questionnaire was designed and sent (mailed and faxed) to vice chancellors, deans, principals or medical directors of the institutions. Reminders were sent through faxes and emails wherever available, followed by phone calls if responses were not available after several attempts. Results: At the time of study, there were 39 medical colleges recognized by Pakistan Medical and Dental Council. Of these, responses were received from 26 teaching institutions in the country. A majority of the respondents (85%) were not satisfied with the care provided in the ED of their primary teaching hospital, and three-fourth (74%) thought that doctors specialized in other disciplines, like internal medicine and family medicine, cannot adequately manage all emergencies. When asked if Pakistan should have a separate residency training programme in emergency medicine, 96% responded in affirmative, and many (85%) thought that they will start a residency programme in emergency medicine if it was approved as a separate specialty. Conclusion: This survey shows significant support for a separate local training programme for emergency medicine in the country. [source] Long-term outcomes of children treated with the ketogenic diet in the pastEPILEPSIA, Issue 7 2010Amisha Patel Summary Purpose:, The ketogenic diet has well-established short- and long-term outcomes for children with intractable epilepsy, but only for those actively receiving it. However, no information exists about its long-term effects years after it has been discontinued. Methods:, Living subjects were identified who were treated at the Johns Hopkins Hospital with the ketogenic diet from November 1993 to December 2008 for ,1 month, and had discontinued it ,6 months prior to this study. Of 530 patients who were eligible, 254 were successfully contacted by phone or e-mail with a survey and request for laboratory studies. Results:, Questionnaires were completed by 101 patients, with a median current age of 13 years (range 2,26 years). Median time since discontinuing the ketogenic diet was 6 years (range 0.8,14 years). Few (8%) still preferred to eat high fat foods. In comparison to the 52% responder rate (>50% seizure reduction) at ketogenic diet discontinuation, 79% were now similarly improved (p = 0.0001). Ninety-six percent would recommend the ketogenic diet to others, yet only 54% would have started it before trying anticonvulsants. Lipids were normal (mean total cholesterol 158 mg/dl), despite most being abnormal while on the ketogenic diet. The mean Z scores for those younger than age 18 years were ,1.28 for height and ,0.79 for weight. In those 18 years of age or older, the mean body mass index (BMI) was 22.2. Discussion:, This is the first study to report on the long-term effects of the ketogenic diet after discontinuation. The majority of subjects are currently doing well with regard to health and seizure control. [source] Information technology supporting diabetes sel-care: a pilot studyEUROPEAN DIABETES NURSING, Issue 1 2007A Halkoaho MSc Diabetes Nurse Specialist Abstract Although diabetes is a lifelong, incurable disease, people can live a full and normal life, provided that they receive appropriate and well-planned care. The care of people with diabetes should be organised as flexibly as possible to suit individual lifestyles. Information technology has become a useful tool to support functional patient,professional relationships and improve care balance. The Self-Care System software tool set by ProWellness is one such tool. Users can enter blood glucose data by using a computer, modem and mobile phone and diabetes nurses can monitor the situation from their own computer and, if necessary, give instructions by sending a SMS (text) message to the patient's mobile phone. This pilot study investigated whether the Self-Care System application supports people with diabetes and can be used as a diabetes education method. The study was carried out in the municipal consortium for healthcare of Siilinjärvi and Maaninka. Nine individuals with diabetes and three diabetes nurses were selected to participate in the study. Data were collected by questionnaire and interview. People with diabetes were sent a questionnaire and the nurses were interviewed. Content analysis was carried out on the interview data. The results suggest that the Self-Care System software supports and motivates diabetes self-care. The nurses felt that the application was useful when changes, such as starting insulin treatment, were introduced. The application was further described as effective and motivating in short-term intensive diabetes education and monitoring; however, both nurses and patients disliked the mechanical nature of the software.

Objective: Pain studies require prospective patient enrollment to ensure accurate pain assessment. The authors correlated pain assessments of an acute painful episode over a one-week period and determined the accuracy of patient pain severity recall over time. Methods: This was a prospective, descriptive, longitudinal study. Participants were a convenience sample of 50 emergency department patients with acute pain resulting from injuries or painful invasive procedures. A trained research assistant administered a structured pain survey containing demographic and historical features to all patients. Patients sequentially assessed their pain severity using a vertical 100-mm visual analog scale marked "most pain" at the top, a verbal numeric rating scale ranging from 0 to 100 from none to worst (NRS100), and a verbal numeric rating scale ranging from 0 to 10 from none to worst (NRS10). Patients were contacted by phone and asked to reassess their initial pain severity one and seven days later using the two verbal numeric rating scales. Analysis of pain assessments using the various scales at the three time intervals was performed with Pearson's and Spearman's coefficients and repeated-measures analysis of variance (ANOVA). Results: There were 50 patients with a mean age of 41 years. Correlation between initial pain assessments on the three scales ranged from 0.83 to 0.92. Correlations between the initial and 24-hour assessments were NRS100-0.98 and NRS10-0.98. Correlations between the initial and one-week assessments were NRS100-0.96 and NRS10-0.97. Repeated-measures ANOVA showed no significant change in pain assessments over time for both verbal numeric scales. Conclusions: Pain severity assessments of acute painful events one and seven days later were similar and highly correlated with initial assessments using both verbal numeric scales. Patients accurately recall the severity of an acute painful episode for at least one week after its occurrence, which may allow retrospective pain assessments. [source] Effect of Professional Postpartum Support on Infant Feeding Patterns Among Breastfeeding Participants in the WIC ProgramFAMILY & CONSUMER SCIENCES RESEARCH JOURNAL, Issue 4 2004Jo Carol Chezem The purpose of this study was to determine if professional breastfeeding support could postpone formula introduction and prolong breastfeeding among participants in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). Fifty women in the experimental group received home visits and phone calls from a lactation educator following hospital discharge; 50 control group women were encouraged to contact a lactation educator as needed. Infants' ages at formula introduction and breastfeeding continuation rates were not significantly different between the groups. Common reasons for breastfeeding cessation included returning to work/school, inadequate milk supply, and latch-on/suckling problems. Use of telephone contacts, delay of breastfeeding support until after hospital discharge, and early formula supplementation may have contributed to the ineffectiveness of the intervention. [source] Teaching and Learning Guide for: Memoryscape: How Audio Walks Can Deepen Our Sense of Place by Integrating Art, Oral History and Cultural GeographyGEOGRAPHY COMPASS (ELECTRONIC), Issue 5 2008Toby Butler Author's Introduction This article is concerned with the history and practice of creating sound walks or ,memoryscapes': outdoor trails that use recorded sound and spoken memory played on a personal stereo or mobile media to experience places in new ways. It is now possible to cheaply and easily create this and other kinds of located media experience. The development of multi-sensory-located media (,locedia') presents some exciting opportunities for those concerned with place, local history, cultural geography and oral history. This article uses work from several different disciplines (music, sound art, oral history and cultural geography) as a starting point to exploring some early and recent examples of locedia practice. It also suggests how it might give us a more sophisticated, real, embodied and nuanced experience of places that the written word just can not deliver. Yet, there are considerable challenges in producing and experiencing such work. Academics used to writing must learn to work in sound and view or image; they must navigate difficult issues of privacy, consider the power relations of the outsider's ,gaze' and make decisions about the representation of places in work that local people may try and have strong feelings about. Creating such work is an active, multi-sensory and profoundly challenging experience that can offer students the chance to master multi-media skills as well as apply theoretical understandings of the histories and geographies of place. Author Recommends 1.,Perks, R., and Thomson, A. (2006). The oral history reader, 2nd ed. London: Routledge. This is a wonderful collection of significant writing concerned with oral history. Part IV, Making Histories features much of interest, including a thought-provoking paper on the challenges of authoring in sound rather than print by Charles Hardy III, and a moving interview with Graeme Miller, the artist who created the Linked walk mentioned in the memoryscape article. These only feature in the second edition. 2.,Cresswell, T. (2004). Place: a short introduction. Oxford, UK: Blackwell.

This article is a thoughtful analysis of a Janet Cardiff sound walk in Whitechapel, East London. Online Materials http://www.memoryscape.org.uk This is my project website, which features two online trails, Dockers which explores Greenwich and the memories of the London Docks that are archived in the Museum of London, and Drifting which is a rather strange experiment-combining physical geography and oral history along the Thames at Hampton Court, but still makes for an interesting trail. Audio, maps and trails can be downloaded for free, so students with phones or iPods can try the trails if you are within reach of Surrey or London. The site features an online version, with sound-accompanying photographs of the location. http://www.portsofcall.org.uk This website has three more trails here, this time of the communities surrounding the Royal Docks in East London. The scenery here is very dramatic and anyone interested in the regeneration of East London and its impact on local communities will find these trails interesting. Like Dockers, the walks feature a lot of rare archive interviews. This project involved a great deal of community interaction and participation as I experimented with trying to get people involved with the trail-making process. The site uses Google maps for online delivery. http://www.soundwalk.com This New York-based firm creates exceptionally high-quality soundwalks, and they are well worth the money. They started by producing trails for different districts of New York (I recommend the Bronx Graffiti trail) and have recently made trails for other cities, like Paris and Varanassi in India. http://www.mscapers.com This website is run by Hewlett Packard, which has a long history of research and development in located media applications. They currently give free licence to use their mscape software which is a relatively easy to learn way of creating global positioning system-triggered content. The big problem is that you have to have a pricey phone or personal digital assistant to run the software, which makes group work prohibitively expensive. But equipment prices are coming down and with the new generations of mobile phones developers believe that the time when the player technology is ubiquitous might be near. And if you ask nicely HP will lend out sets of equipment for teaching or events , fantastic if you are working within reach of Bristol. See also http://www.createascape.org.uk/ which has advice and examples of how mscape software has been used for teaching children. Sample Syllabus public geography: making memoryscapes This course unit could be adapted to different disciplines, or offered as a multidisciplinary unit to students from different disciplines. It gives students a grounding in several multi-media techniques and may require support/tuition from technical staff. 1.,Introduction What is a located mediascape, now and in the future? Use examples from resources above. 2.,Cultural geographies of site-specific art and sound Theories of place; experiments in mapping and site-specific performance. 3.,Walk activity: Westergard Hildekamp , sound walk, or one of the trails mentioned above The best way , and perhaps the only way , to really appreciate located media is to try one in the location they have been designed to be experienced. I would strongly advise any teaching in this field to include outdoor, on-site experiences. Even if you are out of reach of a mediascape experience, taking students on a sound walk can happen anywhere. See Autumn Leaves reference above. 4.,Researching local history An introduction to discovering historical information about places could be held at a local archive and a talk given by the archivist. 5.,Creating located multimedia using Google maps/Google earth A practical exercise-based session going through the basics of navigating Google maps, creating points and routes, and how to link pictures and sound files. 6.,Recording sound and oral history interviews A practical introduction to the techniques of qualitative interviewing and sound recording. There are lots of useful online guides to oral history recording, for example, an online oral history primer http://www.nebraskahistory.org/lib-arch/research/audiovis/oral_history/index.htm; a more in depth guide to various aspects of oral history http://www.baylor.edu/oral%5fhistory/index.php?id=23566 or this simple oral history toolkit, with useful links to project in the North of England http://www.oralhistorynortheast.info/toolkit/chapter1.htm 7.,Sound editing skills Practical editing techniques including working with clips, editing sound and creating multi-track recordings.

Individual or group project work (staff available for technical support) 11.,Presentations/reflection on practice Focus Questions 1What can sound tell us about the geographies of places? 2When you walk through a landscape, what traces of the past can be sensed? Now think about which elements of the past have been obliterated? Whose past has been silenced? Why? How could it be put back? 3Think of a personal or family story that is significant to you. In your imagination, locate the memory at a specific place. Tell a fellow student that story, and describe that place. Does it matter where it happened? How has thinking about that place made you feel? 4What happens when you present a memory of the past or a located vision of the future in a present landscape? How is this different to, say, writing about it in a book? 5Consider the area of this campus, or the streets immediately surrounding this building. Imagine this place in one of the following periods (each group picks one): ,,10,000 years ago ,,500 years ago ,,100 years ago ,,40 years ago ,,last Thursday ,,50 years time What sounds, voices, stories or images could help convey your interpretation of this place at that time? What would the visitor hear or see today at different points on a trail? Sketch out an outline map of a located media trail, and annotate with what you hear/see/sense at different places. Project Idea small group project: creating a located mediascape Each small group must create a located media experience, reflecting an aspect of the history/geography/culture of an area of their choosing, using the knowledge that they have acquired over the course of the semester. The experience may be as creative and imaginative as you wish, and may explore the past, present or future , or elements of each. Each group must: ,,identify an area of interest ,,research an aspect of the area of the groups choosing; this may involve visiting local archives, libraries, discussing the idea with local people, physically exploring the area ,,take photographs, video or decide on imagery (if necessary) ,,record sound, conduct interviews or script and record narration ,,design a route or matrix of media points The final project must be presented on a website, may embed Google maps, and a presentation created to allow the class to experience the mediascape (either in the classroom or on location, if convenient). The website should include a brief theoretical and methodological explanation of the basis of their interpretation. If the group cannot be supported with tuition and support in basic website design or using Google mapping with sound and imagery, a paper map with locations and a CD containing sound files/images might be submitted instead. For examples of web projects created by masters degree students of cultural geography at Royal Holloway (not all sound based) see http://www.gg.rhul.ac.uk/MA/web-projects.html [source] The blessings and burdens of communication: cell phones in Jamaican transnational social fieldsGLOBAL NETWORKS, Issue 2 2006HEATHER A. HORST Tracing the shift from community phone boxes to individually owned mobile (cell) phones in rural Jamaica, in this article I focus on the integration of mobile phones in Jamaican transnational communication. Equipped with a mobile phone, rural Jamaicans no longer rely on collect phone calls and expensive calling cards to initiate the connections between their friends and relatives living abroad. For many Jamaicans without access to a regular or reliable phone service prior to 2001, the mobile phone is viewed as an unadulterated blessing, transforming the role of transnational communication from an intermittent event to a part of daily life. For others, however, the mobile phone remains an object of ambivalence, bringing unforeseen burdens and obligations. [source] Fabrication and Application of an Oxide Thermoelectric SystemINTERNATIONAL JOURNAL OF APPLIED CERAMIC TECHNOLOGY, Issue 4 2007Ryoji Funahashi A plate-shaped thermoelectric module was prepared using 140 pairs of p -type Ca3Co4O9 (Co-349) and n -type LaNiO3 (Ni-113) bulks. The hot-pressed thermoelectric oxide bulks were connected with an Ag paste, incorporating oxide powder, and Ag sheets. The module's open-circuit voltage increases with increasing hot-side temperature (TH) and reaches 4.5 V at a TH of 1072 K in air. No deterioration in output power was seen when power generation was carried out 10 times at a TH of 723 K with intermediate cooling to room temperature. The module was successfully used to charge a lithium-ion battery in a mobile phone. Thermoelectric modules composed of p -type Co-349 and n -type CaMnO3 (Mn-113) bulks, which have a pipe shape, were constructed using Ag electrodes and stainless-steel tubes. The devices were connected with the stainless-steel tube coated with ZrO2 by thermal spray using a dielectric paste composed of silica glass and iron oxide. Power generation was carried out in flame by combustion of natural gas. Water flowed inside the stainless-steel tube for cooling. One module consisting of 54 pairs of legs can generate 1.5 V, 0.28 W, and steam simultaneously by installing in an instantaneous water heater. Power generation was carried out four times with intermediate cooling. Deterioration in the open-circuit voltage of the module was not observed after the fourth combustion. [source] Evaluation of glargine group-start sessions in patients with type 2 diabetes as a strategy to deliver the serviceINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 2 2007A. A. Tahrani Summary Improving glycaemic control in patients with type 2 diabetes reduces microvascular complications. The national service framework for diabetes and the new general medical service contract have been aiming to direct more focus on improving HbA1c. These measures have resulted in increasing number of patients being initiated on insulin therapy, which increases the workload of diabetes specialist nurses (DSNs). Initiating insulin on a one-to-one basis is time consuming. As a result DSN-led insulin group-start sessions were introduced. To evaluate DSN-led glargine group-start and self-titration as a strategy of providing service. We assessed the impact of this method on the use of DSNs time, HbA1c and on patients' satisfaction. A prospective audit in a district general hospital. Groups of 5,7 patients received two 2-h sessions at weeks 0 and 2. During these sessions, patients were initiated on insulin glargine and received an educational package and a self-titration protocol. DSNs did not see patients after week 2. Patients were able to phone the DSNs for advice till the end of the titration period. Patients completed Diabetes Treatment Satisfaction Questionnaire (DTSQ) at baseline, week 2 and 12 months. Weight and HbA1c were assessed at base line and 12 months later. Twenty-nine consecutive patients were included. Baseline HbA1c improved at 6 months and remained stable at 12 months (medians 10.0, 8.7 and 8.9 respectively, p < 0.001). DTSQ score improved between week 0 and 2 and this was maintained at 12 months (medians 26, 35 and 34 respectively, p < 0.001). After week 2, the DSNs spent a median of 21 min advising patients by phone during the titration period. Weight did not increase significantly. In our centre, DSN-led insulin group-start sessions and self-titration improved glycaemic control. Patients were satisfied with this method of starting insulin. This was achieved with minimal DSNs time and input and proved to be effective, yet less time consuming. [source] Patient Response to the Fast-Track ExperienceINTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 2003Jane Flanagan PURPOSE To describe patients' functional health, symptom distress, and recovery at home across a fasttrack perioperative experience. METHODS A nonexperimental, descriptive, correlational design using pre/post test measures and openended questions captured the fast-tracking experience. A convenience sample included 77 patients entering the same-day surgery unit to undergo arthroscopy with general anesthesia and planned fast-track recovery. In the preadmission test area, patients were asked by a nurse to participate in the study. If they agreed and met selection criteria, a nurse completed a demographic sheet, the Foster and Jones Functional Health Pattern Assessment Screeing Tool (FHPAST), and the Symptom Distress Scale (SDS). On the evening of surgery, a nurse called the patient to review the SDS to be completed by phone. At 72 hours after surgery, the FHPAST, the SDS, and a 72-hour open-ended questionnaire were administered to understand the patient experience of fast-tracking. FINDINGS At 12 hours nurses reported patients were "euphoric" and it was difficult to imagine pain or other symptoms. Some patients complained of nausea and fatigue. Most patients had family present. At 72 hours patients described unmet expectations, fatigue, immobility, ineffective pain management, sleep disturbance, and nausea. Interventions included teaching, coaching, and reassurance. Some patients continued to have nursing problems at 72 hours and benefited from a telephone follow-up call. CONCLUSIONS Preliminary results suggest that nursing diagnoses, interventions, and outcomes can be used to describe patient responses to the fast-track experience. Results indicate a need for practice changes to include innovative models and further research to measure outcomes. Fast-tracking can be effective, but requires clinical reasoning by nurses to guide the individual's healing. A coaching intervention seems to enhance patient satisfaction and a sense of being cared for.

Wurm Summary Telemedicine is an emerging field within medicine with potential to revolutionize the delivery of health care. It is defined as the use of telecommunication technologies to transfer medical information.Teledermatology is a category of telemedicine. Early experiments were already made at the beginning of the 20th century, the breakthrough happened in the nineties because of the rapid progress of telecommunication technology. The latest advance is mobile telemedicine which is characterized by the use of mobile devices such as mobile phone and PDA (personal digital assistant).Advantages of telemedicine are the possibility of remote patient-care as well as the easy and fast access to expert opinions and education. This can either happen through exchange of previously stored data/images (store-and-forward method) or in real time. Since our society is increasingly becoming interconnected via technical advances, it is essential that medicine also has an objective understanding of the topic.

(2010) Effectiveness of planning hospital discharge and follow-up in primary care for patients with chronic obstructive pulmonary disease: research protocol. Journal of Advanced Nursing,66(6), 1365,1370. Abstract Title.,Effectiveness of planning hospital discharge and follow-up in primary care for patients with chronic obstructive pulmonary disease: research protocol. Aim., To evaluate the effectiveness of a protocolized intervention for hospital discharge and follow-up planning for primary care patients with chronic obstructive pulmonary disease. Background., Chronic obstructive pulmonary disease is one of the main causes of morbidity and mortality internationally. These patients suffer from high rates of exacerbation and hospital readmission due to active problems at the time of hospital discharge. Methods., A quasi-experimental design will be adopted, with a control group and pseudo-randomized by services (protocol approved in 2006). Patients with pulmonary disease admitted to two tertiary-level public hospitals in Spain and their local healthcare centres will be recruited. The outcome variables will be readmission rate and patient satisfaction with nursing care provided. 48 hours after admission, both groups will be evaluated by specialist coordinating nurses, using validated scales. At the hospital, a coordinating nurse will visit each patient in the experimental group every 24 hours to identify the main caregiver, provide information about the disease, and explain treatment. In addition, the visits will be used to identify care problems and needs, and to facilitate communication between professionals. 24 hours after discharge, the coordinating nurses will inform the primary care nurses about patient discharge and nursing care planning. The two nurses will make the first home visit together. There will be follow-up phone calls at 2, 6, 12 and 24 weeks after discharge. Discussion., The characteristics of patients with this pulmonary disease make it necessary to include them in hospital discharge planning programmes using coordinating nurses. [source] Home Intravenous Antimicrobial Infusion Therapy: A Viable Option in Older AdultsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2007(See editorial comments by Dr. Kevin High on pp 79 OBJECTIVES: To determine whether older adults and younger adults are equally able to administer home intravenous antimicrobial infusion therapy (home IV antimicrobials) without intensive support from home care agencies. DESIGN: Retrospective cohort study. SETTING: Veterans Affairs Ann Arbor Healthcare System, a 100-bed tertiary care medical center. PARTICIPANTS: All patients who received home IV antimicrobials from July 1, 2000, through December 31, 2003. MEASUREMENTS: Demographic data, underlying medical conditions, indications for therapy, antimicrobial agents administered, concomitant medications, frequency of patient visits and phone calls, adverse events, and outcomes of infections. RESULTS: A total of 205 patients received 231 courses of home IV antimicrobials, with 107 courses in patients aged 60 and older and 124 courses in patients younger than 60. For both groups, the most common indication for therapy was osteoarticular infections, and the predominant pathogens were Staphylococcus aureus and coagulase-negative Staphylococcus. Older patients were significantly more likely than younger patients to require the assistance of family members to help with the infusion and were more likely to be seen in urgent care or to call the infectious diseases pharmacist or physicians with questions. Overall, clinical outcomes and numbers of adverse events were similar in both groups, with the exception of nephrotoxicity, which was greater in the older group (P=.02). CONCLUSION: With appropriate support from a hospital-based home IV antimicrobials therapy team, home IV antimicrobial appears to be a viable option for older adults.

Call content and mean duration were similar across conditions. Scheduled -support patients dropped out significantly less often, did more homework of self-exposure and self-imposed ritual prevention (95% vs. 57%), and showed more improvement in OCD symptoms and disability. Mean total support time per patient over 17 weeks was 76 minutes for Scheduled and 16 minutes for Requested patients. Giving brief support proactively by phone enhanced OCD patients' completion of and improvement with computer-aided self-help. © 2005 Wiley Periodicals, Inc. J Clin Psychol 61: 1499,1508, 2005. [source] Computer-aided CBT self-help for anxiety and depressive disorders: Experience of a London clinic and future directionsJOURNAL OF CLINICAL PSYCHOLOGY, Issue 2 2004Lina Gega This article describes a broad-spectrum, computer-aided self-help clinic that raised the throughput of anxious/depressed patients per clinician and lowered per-patient time with a clinician without impairing effectiveness. Many sufferers improved by using one of four computer-aided systems of cognitive behavior therapy (CBT) self-help for phobia/panic, depression, obsessive-compulsive disorder, and general anxiety. The systems are accessible at home, two by phone and two by the Web. Initial brief screening by a clinician can be done by phone, and if patients get stuck they can obtain brief live advice from a therapist on a phone helpline. Such clinician-extender systems offer hope for enhancing the convenience and confidentiality of guided self-help, reducing the per-patient cost of CBT, and lessening stigma. The case examples illustrate the clinical process and outcomes of the computer-aided system. © 2003 Wiley Periodicals, Inc. J Clin Psychol/In Session. [source] Development of a cross-platform ubiquitous language learning service via mobile phone and interactive television,JOURNAL OF COMPUTER ASSISTED LEARNING, Issue 4 2007S. Fallahkhair Abstract This paper describes the development processes for a cross-platform ubiquitous language learning service via interactive television (iTV) and mobile phone. Adapting a learner-centred design methodology, a number of requirements were gathered from multiple sources that were subsequently used in TAMALLE (television and mobile phone assisted language learning environment) development. A number of issues that arise in the context of cross-platform user interface design and architecture for ubiquitous language learning were tackled. Finally, we discuss a multi-method evaluation regime to gauge usability, perceived usefulness and desirability of TAMALLE system. The result broadly revealed an overall positive response from language learners. Although, there were some reported difficulties in reading text and on-screen display mainly on the iTV side of the interface, TAMALLE was perceived to be a usable, useful and desirable tool to support informal language learning and also for gaining new contextual and cultural knowledge. [source] The Internet for educating individuals with social impairmentsJOURNAL OF COMPUTER ASSISTED LEARNING, Issue 4 2003J. Bishop Abstract Social impairments materialise in a number of forms, from developmental disabilities such as autistic spectrum disorder, to psychiatric conditions such as social phobia. The individuals diagnosed with these problems find it difficult to deal with social situations through either the inability to perform in these situations or the fear of not being able to do so. The study investigated the social and practical implications of using Mobile Internet technology to deliver information relating to a social situation in real-time to participants with Autistic Spectrum Disorders (n = 10) and General Social Phobia (n = 3) diagnosed using DSM-IV. The participants used the agent on their mobile phone to convert phrases they found offensive or confusing into more concise and understandable definitions. Analysing their attitudes revealed that the technology enables socially impaired individuals to learn the meaning of emotions and understand more about how they communicate with their peers. However, the study concludes that governmental organisations, education providers and society as a whole need to adopt a cohesive approach to communication to ensure socially impaired individuals are fully included in society [source] Configurations of Relationships in Different Media: FtF, Email, Instant Messenger, Mobile Phone, and SMSJOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 4 2007Hyo Kim This study analyzes the configurations of communication relationships in Korea through face-to-face, email, instant messaging, mobile phone, and short message service media. Through a web survey, we asked respondents to identify (1) for each of the five media (2) up to five of their most frequent communication partners, (3) the partner's social role (including colleagues, family, friends), and (4) their own employment category. Individual-level and network-level analyses were used to compare variations in communication relationships and configurations of relationships among social roles overall, within each medium, and for different employment categories, and to identify configurations of relationships across media. IM, SMS, and mobile phone are distinctive media for students, mobile phone for homeworkers, and email for organizational workers. Moreover, mobile phones tend to be used in reinforcing strong social ties, and text-based CMC media tend to be used in expanding relationships with weak ties. Finally, face-to-face (FtF) seems to be a universal medium without significant differences across respondents' employment categories. [source] The value increment of mass-customized products: an empirical assessmentJOURNAL OF CONSUMER BEHAVIOUR, Issue 4 2006Martin Schreier The primary argument in favour of mass customization is the delivery of superior customer value. Using willingness-to-pay (WTP) measurements, Franke and Piller (2004), Journal of Product Innovation Management, 21, 401,415 have recently shown that customers designing their own watches with design toolkits are willing to pay premiums of more than 100% (,WTP). In the course of three studies, we found that this type of value increment is not a singular occurrence but might rather be a general phenomenon, as we again found average ,WTPs of more than 100% among customers designing their own cell phone covers, T-shirts and scarves. Building on this, we discuss the sources of benefits that are likely to explain this tremendous value increment. We argue that compared to conventional standard products, a mass-customized product might render the following utilitarian and hedonic benefits: (1) First, the output might be beneficial as self-designed products offer a much closer fit between individual needs and product characteristics. In addition to this mere functional benefit, extra value might also stem from (2) the perceived uniqueness of the self-designed product. As the customer takes on the role of an active co-designer, there may also be two general ,do-it-yourself effects': (3) First, the process of designing per se is likely to allow the customer to meet hedonic or experiential needs (process benefit). (4) Customers may also be likely to value the output of self-design more highly if they take pride in having created something on their own (instead of traditionally buying something created by somebody else). This is referred to as the ,pride of authorship' effect. Copyright © 2006 John Wiley & Sons, Ltd. [source] Evaluation of cognitively accessible software to increase independent access to cellphone technology for people with intellectual disabilityJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 12 2008S. E. Stock Abstract Background There are over two billion telephones in use worldwide. Yet, for millions of Americans with intellectual disabilities (ID), access to the benefits of cellphone technology is limited because of deficits in literacy, numerical comprehension, the proliferation of features and shrinking size of cellphone hardware and user interfaces. Developments in smart phone technology and PDA-based cellphones provide an opportunity to make the social and safety benefits of cellphones more independently accessible to this population. Method This project involved employment of universal design and other specialised software development methods to create a multimedia cellphone interface prototype which was compared with a typical mainstream cellphone in a usability evaluation for individuals with ID. Participants completed a structured set of incoming/outgoing phone tasks using both the experimental and control conditions. Usability measurements included the amount of assistance needed and errors made in completing the cellphone use sequence. Results A total of 22 individuals with ID participated in the research by engaging in a series of incoming and outgoing cellphone calls using both the multimedia cellphone prototype system and a mainstream Nokia 6360 cellphone. Test subjects required significantly less help (P = 0.001) and made significantly fewer errors (P < 0.001) when completing eight calls using the specialised multimedia phone system as compared with the mainstream phone. Conclusions The statistical evidence of both usability results provide promising evidence of the feasibility of implementing universal design and other specialised software development methodologies for increasing independent access to the benefits of cellphone technologies for students and adults with ID. Issues related to designing cognitively accessible interfaces, study limitations and future directions are discussed. [source] Breastfeeding Support and Early CessationJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 2 2006Lynne Porter Lewallen Objective:, To examine the types of help women received with breastfeeding both in the hospital and at home and the reasons why women stopped breastfeeding earlier than intended. Design:, A descriptive design with open-ended questions. Setting:, After participant recruitment in the postpartum hospital room, data were collected by phone 8 weeks after delivery. Patients/Participants:, Three hundred seventy-nine women planning to breastfeed for at least 8 weeks after uncomplicated delivery. Main Outcome Measures:, Breastfeeding status at 8 weeks postpartum; report of help with breastfeeding in the hospital and at home. Results:, Sixty-eight percent of women were still breastfeeding at 8 weeks, although 37% of those reported supplementing with formula. Of those who had stopped, the most common reason was insufficient milk supply. Other reasons included painful nipples and latch problems, personal reasons, returning to work or school, and drugs/illness of the mother or baby. Most women received help with breastfeeding in the hospital, but only 55% received help with breastfeeding after hospital discharge. Conclusions:, The primary reasons for early cessation of breastfeeding are amenable to nursing intervention. Every opportunity should be taken to address these issues both in the hospital and through follow-up calls. JOGNN, 35, 166-172; 2006. DOI: 10.1111/J.1552-6909.2006.00031.x. [source] Cell phone roulette and "consumer interactive" qualityJOURNAL OF POLICY ANALYSIS AND MANAGEMENT, Issue 2 2005Peter Navarro Under current policies, cell phone consumers face a lower probability of finding the best carrier for their usage patterns than winning at roulette. Corroborating survey data consistently show significant dissatisfaction among cell phone users, network performance is a major issue, and customer "churn" is high. This problem may be traced to a new form of "consumer interactive" quality characteristic of emergent high technology products such as cell phone and broadband services. This problem is unlikely to be resolved by effective search and sampling, efficient secondary markets, or voluntary carrier disclosure. Traditional one-dimensional disclosure responses to this new variation on an old asymmetric information problem should give way to a more multi-faceted and fine-grained policy approach. © 2005 by the Association for Public Policy Analysis and Management [source] | |||||||||||||||||||||||||||||||
