    Cellular phones, used in automobiles, airliners, and passenger trains, are basically low-power radiotelephones. Calls go through radio transmitters that are located within small geographical units called cells. Because each cell’s signals are too weak to interfere with those of other cells operating on the same fre-

    -up of a large nationwide cohort of 420,095 persons whose first cellular telephone subscription was between 1982 and 1995 and who were followed through 2002 for cancer incidence. Standardized incidence ratios (SIRs) were calculated by dividing the number of observed cancer cases in the cohort by the number....... The risk for smoking-related cancers was decreased among men (SIR = 0.88, 95% CI = 0.86 to 0.91) but increased among women (SIR = 1.11, 95% CI = 1.02 to 1.21). Additional data on income and smoking prevalence, primarily among men, indicated that cellular telephone users who started subscriptions in the mid...

    A finite element thermal model of the head has been developed to calculate temperature rises generated in the brain by radiation from cellular telephones and similar electromagnetic devices. A 1 mm resolution MRI dataset was segmented semiautomatically, assigning each volume element to one of ten tissue types. A finite element mesh was then generated using a fully automatic tetrahedral mesh generator developed at NRPB. There are two sources of heat in the model: firstly the natural metabolic heat production; and secondly the power absorbed from the electromagnetic field. The SAR was derived from a finite difference time domain model of the head, coupled to a model `mobile phone', namely a quarter-wavelength antenna mounted on a metal box. The steady-state temperature distribution was calculated using the standard Pennes `bioheat equation'. In the normal cerebral cortex the high blood perfusion rate serves to provide an efficient cooling mechanism. In the case of equipment generally available to the public, the maximum temperature rise found in the brain was about 0.1 °C. These results will help in the further development of criteria for exposure guidelines, and the technique developed may be used to assess temperature rises associated with SARs for different types of RF exposure.

    Full Text Available Abstract Background The use of cellular and cordless telephones has increased dramatically during the last decade. There is concern of health problems such as malignant diseases due to microwave exposure during the use of these devices. The brain is the main target organ. Methods Since the second part of the 1990's we have performed six case-control studies on this topic encompassing use of both cellular and cordless phones as well as other exposures. Three of the studies concerned brain tumours, one salivary gland tumours, one non-Hodgkin lymphoma (NHL and one testicular cancer. Exposure was assessed by self-administered questionnaires. Results Regarding acoustic neuroma analogue cellular phones yielded odds ratio (OR = 2.9, 95 % confidence interval (CI = 2.0–4.3, digital cellular phones OR = 1.5, 95 % CI = 1.1–2.1 and cordless phones OR = 1.5, 95 % CI = 1.04–2.0. The corresponding results were for astrocytoma grade III-IV OR = 1.7, 95 % CI = 1.3–2.3; OR = 1.5, 95 % CI = 1.2–1.9 and OR = 1.5, 95 % CI = 1.1–1.9, respectively. The ORs increased with latency period with highest estimates using > 10 years time period from first use of these phone types. Lower ORs were calculated for astrocytoma grade I-II. No association was found with salivary gland tumours, NHL or testicular cancer although an association with NHL of T-cell type could not be ruled out. Conclusion We found for all studied phone types an increased risk for brain tumours, mainly acoustic neuroma and malignant brain tumours. OR increased with latency period, especially for astrocytoma grade III-IV. No consistent pattern of an increased risk was found for salivary gland tumours, NHL, or testicular cancer.

    Introduction. Although an extensive body of literature suggests that face-to-face problem-solving interventions are an effective means of fostering psychiatric medication adherence for persons with SSDs, the majority of outpatients with SSDs lack access to this proven intervention. There is a need for exploration of alternate delivery methods for problem solving. Design. This randomized controlled trial will examine the effectiveness of cellular telephone delivered Telephone Intervention - Problem Solving (TIPS) upon medication adherence, medication self efficacy and symptom management in outpatients with SSDs over 9 monthsMethods. To ensure consistent telephone access, all one hundred twenty eight participants will be provided a basic cellular telephone with unlimited local calling for 9 months. Participants will be randomly assigned to treatment as usual plus weekly TIPS or treatment as usual only (TAU). Assessment of serum medication levels, pill count medication adherence, medication attitudes and psychiatric symptoms will be conducted at baseline and every 3 months on all participants. Summary.In addition to testing the long term effect of TIPS, this study will provide information on the responses to our cellular telephone delivery method. We believe this information will be critical as we continue to explore a variety of cellular telephone technologies to provide needed interventions to persons with SSDs in a feasible, economical way.

  7. Satellite augmentation of cellular type mobile radio telephone systems

    Anderson, Roy E.

    NASA's ATS-6 satellite relayed voice bandwidth communications between five trucks and the trucking company dispatchers as the trucks traveled throughout the north-eastern quarter of the contiguous United States. The experiment, conducted over a seven month period, demonstrated that propagation characteristics are much different for the satellite-mobile links than for terrestrial-mobile links. A properly designed satellite system can provide high quality, reliable voice and data communications except where the vehicle-satellite path is shadowed by a structure or terrain feature. Mobile equipment in the experiment was adapted from commercial mobile radios. The vehicle antennas were 75 cm tall, 2 cm diam. Another experiment proved the feasibility of vehicle position surveillance using active two-way tone-code ranging through ATS-6 to provide one line of position and passive one-way ranging by measuring the time-of-arrival of a signal from an independent satellite. A position fix was printed out at an earth station 1 sec after it sent the interrogation signal to the distant vehicle, a towboat on the Mississippi River. The line of position from ATS-6 was accurate to 0.1 nautical mile using a voice bandwidth ranging signal. The line of position from the NOAA GOES satellite was accurate to 2 miles, using 100 Hz signal bandwidth. If the signal from the independent satellite had the same bandwidth and signal-to-noise ratio as ATS-6, the fixes would have been accurate to about 0.1 nautical mile. A concept study concluded that satellites might be a cost effective augmentation of terrestrial cellular type mobile radio telephone systems. The satellites would serve thinly populated areas where terrestrial systems are not cost effective. In the United States, the satellites would serve about 90% of the land area where 20% of the population resides. A multibeam satellite with many channels in each beam would be compatible with the urban terrestrial systems and together they would

    We developed a new telemedicine system to monitor the condition of continuous ambulatory peritoneal dialysis (CAPD) patients by using a cellular telephone and an Internet Web site. All data for the CAPD patients--blood pressure, heart rate, body weight, ultrafiltration volume, and urine volume--are collected and sent directly by cellular telephone to a data server that was constructed at the NTT DoCoMo Company data center. The system is directly connected to Internet by application service provider (ASP) technology. Anywhere, at any time, each patient can confirm changes in their data in graph form by using a cellular telephone or a computer connection to an Internet Web site. The average of each type of data is calculated and shown at the Web site. All data collected by cellular telephone are calculated and, in real time, sent directly to the treating physician's office over the Internet. Abnormal data are sent directly to the treating physician's office and shown in the host computer with an emergency signal (emergency alarm system). In addition, CAPD patients can easily contact the medical staff in the Kidney and Dialysis Center of Saitama Medical School (main hospital) using the same telemedicine system. We are using this telemedicine system for 46 CAPD patients being treated by Saitama Medical School. The cost of using the system is just US$3.00 or less per month for each patient. This newly developed system has great advantages for CAPD patients, especially elderly and handicapped patients. The system can be expanded into a network that serves all CAPD patients and all hospitals in Japan.

    Full Text Available Background: Predictors of relapse to methamphetamine use are poorly understood. State variables may play an important role in relapse, but they have been difficult to measure at frequent intervals in outpatients.Methods: We conducted a feasibility study of the use of cellular telephones to collect state variable data from outpatients. Six subjects in treatment for methamphetamine dependence were called three times per weekday for approximately seven weeks. Seven questionnaires were administered that assessed craving, stress, affect and current type of location and social environment.Results: 395/606 (65% of calls attempted were completed. The mean time to complete each call was 4.9 (s.d. 1.8 minutes and the mean time to complete each item was 8.4 (s.d. 4.8 seconds. Subjects rated the acceptability of the procedures as good. All six cellular phones and battery chargers were returned undamaged.Conclusion: Cellular telephones are a feasible method for collecting state data from methamphetamine dependent outpatients.

    The aetiology of brain tumours is poorly understood. Due, in part, to public concern about a postulated relationship between the use of cellular telephones or other increasingly prevalent environmental exposures and the incidence of brain cancer in adults, the National Cancer Institute is collaborating with three US hospitals in a comprehensive case control study of malignant and benign brain tumours. Factors under consideration include use of cellular phones and other wireless communication devices, workplace exposures to chemical agents and electromagnetic fields, dietary factors, family history of tumours, genetic determinants of susceptibility, home appliance use, reproductive history and hormonal exposures, viruses, medical and dental exposure to ionising radiation, and other aspects of medical history. Approximately 800 newly diagnosed brain tumour cases and 800 controls were enrolled at hospitals in Boston, Phoenix and Pittsburgh from 1994 to 1998. Cases include all adults (age {>=} 18 y) newly diagnosed with a histologically confirmed intracranial glioma, histologically confirmed intracranial meningioma or acoustic neuroma. Controls are patients admitted to the same hospitals as the cases, and treated for any of a variety of non-malignant conditions. Key features of the study include its large size, the emphasis on rapid ascertainment of incident cases and interview of study subjects rather than surrogate respondents, the use of detailed, job-specific questions developed by industrial hygienists to ascertain occupational exposures, and the storage of blood samples for future evaluation of inherited susceptibility, biomarkers of exposure and gene environment interactions.

    Radio wave frequency (RF) radiation emitted from cellular telephones has become increasingly ubiquitous as a result of the popularity of these phones. With the increasing and unavoidable exposure to RF radiation a reality, it is imperative that the effects of such radiation on living tissue be well understood. In particular, it is critical to understand any effects that RF radiation may have as a carcinogen and on embryonic development, as pregnant women are not exempt from such exposure. As a model organism, zebrafish (Danio rerio) have been studied extensively, and their value in studies of gene expression cannot be overstated. This study observed the effects of RF radiation on the embryonic development of zebrafish. The expression of two genes, shha and hoxb9a, that are key to the early development of the fish was examined. Both genes have homologs in humans as well as in other model organisms. Preliminary results suggest that exposure to cell phone radiation might have an effect on the expression of shha in zebrafish embryos, causing under expression. More trials are necessary to validate these results.

    Pollution caused by the electromagnetic fields (EMFs) of radio frequencies (RF) generated by the telecommunication system is one of the greatest environmental problems of the twentieth century. The purpose of this research was to verify the existence of a spatial correlation between base station (BS) clusters and cases of deaths by neoplasia in the Belo Horizonte municipality, Minas Gerais state, Brazil, from 1996 to 2006 and to measure the human exposure levels to EMF where there is a major concentration of cellular telephone transmitter antennas. A descriptive spatial analysis of the BSs and the cases of death by neoplasia identified in the municipality was performed through an ecological-epidemiological approach, using georeferencing. The database employed in the survey was composed of three data banks: 1. death by neoplasia documented by the Health Municipal Department; 2. BSs documented in ANATEL ('Agencia Nacional de Telecomunicacoes': 'Telecommunications National Agency'); and 3. census and demographic city population data obtained from official archives provided by IBGE ('Instituto Brasileiro de Geografia e Estatistica': 'Brazilian Institute of Geography and Statistics'). The results show that approximately 856 BSs were installed through December 2006. Most (39.60%) of the BSs were located in the 'Centro-Sul' ('Central-Southern') region of the municipality. Between 1996 and 2006, 7191 deaths by neoplasia occurred and within an area of 500 m from the BS, the mortality rate was 34.76 per 10,000 inhabitants. Outside of this area, a decrease in the number of deaths by neoplasia occurred. The greatest accumulated incidence was 5.83 per 1000 in the Central-Southern region and the lowest incidence was 2.05 per 1000 in the Barreiro region. During the environmental monitoring, the largest accumulated electric field measured was 12.4 V/m and the smallest was 0.4 V/m. The largest density power was 40.78 {mu

    Peripheral blood samples collected from four healthy nonsmoking human volunteers were diluted with tissue culture medium and exposed in vitro for 24 h to 847.74 MHz radiofrequency (RF) radiation (continuous wave), a frequency employed for cellular telephone communications. A code division multiple access (CDMA) technology was used with a nominal net forward power of 75 W and a nominal power density of 950 W/m(2) (95 mW/cm(2)). The mean specific absorption rate (SAR) was 4.9 or 5.5 W/kg. Blood aliquots that were sham-exposed or exposed in vitro to an acute dose of 1.5 Gy of gamma radiation were included in the study as controls. The temperatures of the medium during RF-radiation and sham exposures in the Radial Transmission Line facility were controlled at 37 +/- 0.3 degrees C. Immediately after the exposures, lymphocytes were cultured at 37 +/- 1 degrees C for 48 or 72 h. The extent of genetic damage was assessed from the incidence of chromosome aberrations and micronuclei. The kinetics of cell proliferation was determined from the mitotic indices in 48-h cultures and from the incidence of binucleate cells in 72-h cultures. The data indicated no significant differences between RF-radiation-exposed and sham-exposed lymphocytes with respect to mitotic indices, frequencies of exchange aberrations, excess fragments, binucleate cells, and micronuclei. The response of gamma-irradiated lymphocytes was significantly different from that of both RF-radiation-exposed and sham-exposed cells for all of these indices. Thus there was no evidence for induction of chromosome aberrations and micronuclei in human blood lymphocytes exposed in vitro for 24 h to 847.74 MHz RF radiation (CDMA) at SARs of 4.9 or 5.5 W/kg.

    Full Text Available OBJECTIVE: The aim of this study was to investigate the possible effects of electromagnetic radiation from conventional cellular phone use on the oxidant and antioxidant status in rat blood and testicular tissue and determine the possible protective role of vitamins C and E in preventing the detrimental effects of electromagnetic radiation on the testes. MATERIALS AND METHODS: The treatment groups were exposed to an electromagnetic field, electromagnetic field plus vitamin C (40 mg/kg/day or electromagnetic field plus vitamin E (2.7 mg/kg/day. All groups were exposed to the same electromagnetic frequency for 15, 30, and 60 min daily for two weeks. RESULTS: There was a significant increase in the diameter of the seminiferous tubules with a disorganized seminiferous tubule sperm cycle interruption in the electromagnetism-exposed group. The serum and testicular tissue conjugated diene, lipid hydroperoxide, and catalase activities increased 3-fold, whereas the total serum and testicular tissue glutathione and glutathione peroxidase levels decreased 3-5 fold in the electromagnetism-exposed animals. CONCLUSION: Our results indicate that the adverse effect of the generated electromagnetic frequency had a negative impact on testicular architecture and enzymatic activity. This finding also indicated the possible role of vitamins C and E in mitigating the oxidative stress imposed on the testes and restoring normality to the testes.

    Many people have to use English on the telephone in the course of their work, either at the level of taking a simple message or involving more complex tasks such as requesting information. Telephoning in English provides an up-to-date and relevant context in which students from lower-intermediate level upwards can develop practical telephone skills. The course principally develops spoken interactive skills, but also includes reading material on telephone systems and techniques. As the material is not restricted to particular job functions, it is suitable for students in a wide range of business and administration fields.

It is also hoped that this essay can help to pave a foundation for further in-depth study in telephone conversations.

  15. Speech Communication and Telephone Networks

    Science.gov (United States)

    Gierlich, H. W.

    Speech communication over telephone networks has one major constraint: The communication has to be “real time”. The basic principle since the beginning of all telephone networks has been to provide a communication system capable of substituting the air path between two persons having a conversation at 1-m distance. This is the so-called orthotelephonic reference position [7]. Although many technical compromises must be made to enable worldwide communication over telephone networks, it is still the goal to achieve speech quality performance which is close to this reference.

  19. Calling(sup SM) network: A global telephone utility

    Science.gov (United States)

    Tuck, Edward F.; Patterson, David P.; Stuart, James R.; Lawrence, Mark H.

    There is a very large demand for basic telephone service in developing nations and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centers of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain those economies of scale require that the system use Ka-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st century.

    2008-11-01

    Full Text Available Abstract Background Epidemiological and other studies that require participants to respond by completing a questionnaire face the growing threat of non-response. Response rates to household telephone surveys are diminishing because of changes in telecommunications, marketing and culture. Accordingly, updated information is required about the rate of telephone listing in directories and optimal strategies to maximise survey participation. Methods A total of 3426 households in Sydney, Australia were approached to participate in a computer assisted telephone interview (CATI regarding their domestic (recycled and/or drinking water usage. Only randomly selected households in the suburb and postcode of interest with a telephone number listed in the Electronic White Pages (EWP that matched Australian electoral records were approached. Results The CATI response rate for eligible households contacted by telephone was 39%. The rate of matching of electoral and EWP records, a measure of telephone directory coverage, was 55%. Conclusion The use of a combination of approaches, such as an advance letter, interviewer training, establishment of researcher credentials, increasing call attempts and targeted call times, remains a good strategy to maximise telephone response rates. However, by way of preparation for future technological changes, reduced telephone number listings and people's increasing resistance to unwanted phone calls, alternatives to telephone surveys, such as internet-based approaches, should be investigated.

  9. Mandarin recognition over the telephone

    Mandarin Chinese is the official language in China and Taiwan, it is the native language of a quarter of the world population. As the services enabled by speech recognition technology (e.g. telephone voice dialing, information query) become more popular in English, we would like to extend this capability to other languages. Mandarin is one of the major languages under research in our laboratory. This paper describes how we extend our work in English speech recognition into Mandarin. We will described the corpus: Voice Across Taiwan, the training of a complete set of Mandarin syllable models, preliminary performance results and error analysis. A fast prototyping system was built, where a user can write any context free grammar with no restriction of vocabulary, then the grammar can be compiled into recognition models. It enables user to quickly test the performance of a new vocabulary.

    Mayer, Jonathan; Mutchler, Patrick; Mitchell, John C

    2016-05-17

    Since 2013, a stream of disclosures has prompted reconsideration of surveillance law and policy. One of the most controversial principles, both in the United States and abroad, is that communications metadata receives substantially less protection than communications content. Several nations currently collect telephone metadata in bulk, including on their own citizens. In this paper, we attempt to shed light on the privacy properties of telephone metadata. Using a crowdsourcing methodology, we demonstrate that telephone metadata is densely interconnected, can trivially be reidentified, and can be used to draw sensitive inferences.

  16. The shape of telephone cord blisters

    Ni, Yong; Yu, Senjiang; Jiang, Hongyuan; He, Linghui

    2017-01-01

    Formation of telephone cord blisters as a result of buckling delamination is widely observed in many compressed film-substrate systems. Here we report a universal morphological feature of such blisters characterized by their sequential sectional profiles exhibiting a butterfly shape using atomic force microscopy. Two kinds of buckle morphologies, light and heavy telephone cord blisters, are observed and differentiated by measurable geometrical parameters. Based on the Föppl-von Kármán plate theory, the observed three-dimensional features of the telephone cord blister are predicted by the proposed approximate analytical model and simulation. The latter further replicates growth and coalescence of the telephone cord into complex buckling delamination patterns observed in the experiment.

  17. The Telephone: An Invention with Many Fathers

    Energy Technology Data Exchange (ETDEWEB)

    2008-10-01

    The names of A.G. Bell, A. Meucci, P.Reis, E. Gray, just to mention the most important ones, are all connected with the invention of the telephone. Today, the Italian inventor A. Meucci is recognized as being the first to propose a working prototype of the electric telephone. However, for a series of reasons his strenuous efforts were not rewarded. I will not repeat here the endless and complex disputes about the 'real father' of the telephone. From an historical point of view it is more interesting to understand why so many individuals from different backgrounds conceived of a similar apparatus and why most of these devices were simply forgotten or just remained laboratory curiosities. The case of the development of the telephone is an emblematic and useful example for better understanding the intricate factors which are involved in the birth of an invention and reasons for its success and failure.

  3. Tips for telephone and electronic medical consultation.

    Science.gov (United States)

    Gupta, Sailesh G

    2013-11-01

    The world is gradually shrinking in terms of time, and communications, while expanding in terms of population and distances. Patients demand and expect telephone and e-mail consultations and medical professionals are only too happy to oblige. However, a telephone consult is never so satisfying for the patients and well as the doctor as a face consult. Besides much essential information, cues and clues to diagnosis may be missed only with an audio input from patients. A telephone consult should be offered only to know the patient, and only after a prior face consult. It should be ensured that the patient can definitely understand, and follow the directions, and manage the disorder at home. While a telephone consultation may be considered convenient and short, there may be several disadvantages of such consultation, a wrong diagnosis and an inappropriate prescription being just two of them. Telephone etiquette should be followed by the staff and the physician. A triage system may be set up to filter calls that need to be necessarily answered by the physician himself. Telephone consults should be charged, and should be followed by a face consult as soon as possible. E-mail consultations are governed essentially by the same principles that govern telephone consultations. There is a slight advantage of e-mail consultation in that reports can be submitted online, including radiological reports. However, confidentiality is an important and uncertain issue in cyber space. A memorandum of understanding maybe signed between the patient and the physician. The information provided on e-mail should be of a general nature and a face consult should precede e-mail consultation. Patients may be referred to web resources for information. Telemedicine is a useful tool to obtain a medical diagnosis and to provide medical advice, and is likely to be used vastly in the near future.

  4. Critics voice concerns about counseling by telephone.

    Science.gov (United States)

    1996-05-31

    A key issue in the debate over the Confide HIV-antibody home test kit is whether face-to-face counseling about HIV is necessary. The Confide kit, developed by Direct Access Diagnostics, includes written materials for pre-test counseling written by former U.S. Surgeon General C. Everett Koop. Telephone counselors have been trained in consultation with the American Social Health Association and Cicatelli Associations, which trains for the New York State Health Department. Currently, 17 percent of Americans who undergo HIV-antibody testing get the results by telephone, according to 1992 data from the National Health Interview Survey. The AIDS Foundation Houston feels telephone counseling is not sufficient. Additionally, the National Association of People with AIDS (NAPWA) is concerned that callers who hear the recorded message announcing they tested negative will hang up the telephone without listening to additional information about how to take precautions to remain uninfected. Anna Forbes, an AIDS policy consultant, points out that Confide's counseling method also makes it harder to emphasize the fact that a negative test result does not necessarily mean the person is uninfected. Currently, Direct Access Diagnostics is the only company offering HIV-antibody home test kits. At least two other companies are awaiting approval from the Food and Drug Administration (FDA) to begin marketing of a home test kit over the counter: ChemTrak, based in Sunnyvale, CA, and Home Access, based in Chicago.

    By integrating the ground based infrastructure component of a mobile satellite system with the infrastructure systems of terrestrial 800 MHz cellular service providers, a seamless network of universal coverage can be established. Users equipped for both cellular and satellite service can take advantage of a number of features made possible by such integration, including seamless handoff and universal roaming. To provide maximum benefit at lowest posible cost, the means by which these systems are integrated must be carefully considered. Mobile satellite hub stations must be configured to efficiently interface with cellular Mobile Telephone Switching Offices (MTSO's), and cost effective mobile units that provide both cellular and satellite capability must be developed.

    2012-01-01

    In an age where near-instantaneous communication is available through all manners of portable and pocket-sized devices, it is easy to overlook the genesis of telecommunication instrumentation-the telephone. Since Alexander Graham Bell patented the first phone in the 1800s, the telephone has undergone numerous changes to its look and functionality. This detailed volume examines the development of the telephone and related technologies, including everything from the transistor to fax machines, smart phones, and VoIP technology.

  1. Performance Evaluation of Different QoS Models for Connecting Telephone Exchange Centers over Metro Ethernet Networks

    2009-12-01

    Full Text Available Recent large deployment of high-speed metro Ethernet networks creates opportunity to connect legacy telephone exchange centers and cellular telephone base stations to the core telephony network. The success of data and legacy voice services convergence shall depend on whether it can provide the customer with the required QoS or not. Packet-base telephony service requires stringent bounds on end-to-end packet delay, jitter, and loss. New protocols such as MPLS and Diffserv are realized due to the major advantages associated with them such as QoS. This paper studies the performance of connecting telephone exchange centers over a metro Ethernet network using MPLS and DiffServ QoS model. We will implement some simulations to evaluate the performance in terms of delay, jitter and loss.

    Full Text Available The arrears problem puzzled most mobile communication corporations in China. In information theory, the Shannon entropy is a measure of the uncertainty in a signal or random event. Motivated by entropy theory especially the Shannon Entropy, in this study, one called customer information entropy is defined and proposed to credit evaluation for arrearage customers of cellular telephone. The proposed customer information entropy is based on customer’s behavior attributes. Arrearage customers often include malevolent ones and non-malevolent ones. 52364 arrearage customers among a total number of 400000 ones in a mobile communication corporation are chosen for experiment. The proposed measure yields good results in its application of credit evaluation for 52364 arrearage customers in August and September. Its correct evaluation rates for malevolent and non-malevolent of the 52364 arrearage ones both are over 90.0%: among the 52364 arrearage customers, 90.75% of the non-malevolent ones, whose entropy changes is less than zero, while for the entropy changes of the malevolent ones, 95.36% is equal to zero and 1.57% is more than zero. The experimental results indicate that the entropy changes of the non-malevolent ones could be considered as negative and nonnegative for the malevolent ones. The proposed show its potential practicality.

  3. Telephone operator change: your questions answered

    CERN Bulletin

    2015-01-01

    CERN will be changing mobile telephone operators on 24 June. As the community prepares for the summer switchover, everyone has questions. What brought on the change? Why are we losing our old phone numbers? What kind of improvements will we see? "Just as with every contract at CERN, we issue calls for tenders every few years to ensure we are still receiving the best possible service," explains Tony Cass, from the Communication Systems group within the IT department. "As we came to the end of our contract with Sunrise, we put out a call for tenders, which was won by Swisscom. Not only is their pricing more competitive, they will also be providing better service conditions." The scope of these new service conditions is multifaceted: there will be improvements to the redundancy and reliability of the network as well as modern 4G network coverage in the LHC tunnel. "People will also see their mobile phone bills decrease," says Tony. "This will esp...

    Mobile telephones with an integrated camera can provide a unique mechanism for collecting dietary information that reduces burden on record-keepers. Objectives for this study were to test whether participant's proficiency with the mobile telephone food record improved after training and repeated use and to measure changes in perceptions regarding use of the mobile telephone food record after training and repeated use. Seventy-eight adolescents (26 males, 52 females) ages 11 to 18 years were recruited to use the mobile telephone food record for one or two meals. Proficiency with the mobile telephone food record was defined as capturing a useful image for image analysis and self-reported ease of use. Positive changes in perceptions regarding use of the mobile telephone food record were assumed to equate to potentially improved proficiency with the mobile telephone food record. Participants received instruction for using the mobile telephone food record prior to their first meal, and captured an image of their meals before and after eating. Following the first meal, participants took part in an interactive session where they received additional training on capturing images in various snacking situations and responded to questions about user preferences. Changes in the participants' abilities to capture useful images and perceptions about the usability of the mobile telephone food record were examined using McNemar, Wilcoxon rank-sum test, and paired t test. After using the mobile telephone food record, the majority of participants (79%) agreed that the software was easy to use. Eleven percent of participants agreed taking images before snacking would be easy. After additional training, the percent increased significantly to 32% (Ptechnologies; however, the mobile telephone food record design needs to accommodate the lifestyles of its users to ensure useful images and continuous use. Further, these results suggest that additional training in using a new technology may

    2013-10-01

    The participation of service users in all aspects of mental health service delivery including policy development, service planning and evaluation is increasingly an expectation of contemporary mental health care. Although there are a growing number of publications reporting service-user perspectives in the evaluation of mental health services, little attention has been paid to the views of service users about mental health triage services. The purpose of the study reported here was to examine service-users' (consumers and informal carers) experiences of a telephone-based mental health triage service. Using a framework developed from the World Health Organisation's elements of responsiveness, we conducted structured telephone interviews with service users who had contacted a telephone-based mental health triage service in regional Victoria, Australia. The main findings of the study were that consumers experienced more difficulty than carers in accessing the service and that, although most participants were satisfied, only a minority reported being involved in decision-making. Further work is needed to improve accessibility of mental health triage services and to investigate barriers to consumer self-referral. Professional development and practice support systems should be established to support mental health triage nurses in the development of collaborative, consumer-focused care.

    2015-10-01

    Full Text Available Telephone focus groups have been increasingly popular in public health research and evaluation. One of the main concerns of telephone focus groups is the lack of nonverbal cues among participants, which could limit group interactions and dynamics during the focus group discussion. To overcome this limitation, we supplemented telephone focus groups with webinar technology in a recent evaluation of a provincial public health program in Ontario, Canada. In this article, we share the methods used and our experiences in conducting telephone focus groups supplemented with webinar technology, including advantages and challenges. Our experience will inform other researchers who may consider using telephone focus groups with webinars in future research and evaluation.

    Directory of Open Access Journals (Sweden)

    Olubunmi Philip Aborisade

    2012-09-01

    Full Text Available Telephone technology is a technology that stands the test of time. Since it was invented in 1876 by Alexander Graham Belle, it remains the technology of all time. This article reports the major finding of a recent research, how technology transforms citizen journalism business in Nigeria. According to the research, Telephone technology has over the years emerged the major tool with which ordinary citizens in Nigeria without journalism and media background or affiliation participate in the process of news gathering, reporting and distribution. Guided by the recent use of telephone around the world by ordinary citizens to report themselves during protests through different social media outlets-Facebook, Tweeter, Youtube, the article illuminates the evergreen nature of the telephone. The article therefore concluded that the telephone technology invented in 1876 has survived the test of time. Instead of being obsolete, it blends with emerging communications technology to improve on its performance.

  17. Localization of troubles in telephone cable networks

    Energy Technology Data Exchange (ETDEWEB)

    Chuxin Chen; Hollidge, T.L.; Sharma, D.D. [Pacific Bell, San Ramon, CA (United States)

    1996-12-31

    This paper describes an intelligent system which detects the location of troubles in a local telephone cable network. Such a task is very challenging, tedious, and requires human experts with years of experience and high analytical skills. Our system captures the expertise and knowledge required for this task, along with automated access to database systems, so that the system can help a human analyst to pin-point network trouble location more efficiently and accurately, ultimately reducing the cost of maintenance and repair. The system utilizes probabilistic reasoning techniques and logical operators to determine which plant component has the highest failure probability. This is achieved by building a topology of the local cable network, constructing a causal net which contains belief of failure for each plant component, given their current status, history data, cable pair distribution, and connectivity to other components. The Trouble Localization (TL) Module described in this paper is a crucial part of a larger system: Outside Plant Analysis System (OPAS) which has been deployed Statewide for over nine months at Pacific Bell PMAC centers. The TL system module utilizes AI and Object-Oriented technology. It is implemented in C++ on Unix workstations, and its graphical user interface is in an X Window environment.

    2007-01-01

    The telephone is usually the first contact a prospective or new patient has with a medical practice. It is also the method that existing patients and others commonly use to ask questions or convey information. At the same time, a telephone that rings off the hook can be one of the biggest drains on staff time and a source of tremendous frustration. This article suggests practical techniques for managing the medical practice telephone. It provides seven never-fail strategies for saving time on the phone while remaining courteous and attentive to callers. It offers tips to help readers avoid getting caught in an endless game of telephone tag. The article highlights strategies that work particularly well when placing calls and when dealing with a busy signal or voicemail system problem in the practice. It also describes the fine points for taking accurate and complete telephone messages without turning off callers or misleading them. This article further explores practical strategies for using and not abusing the hold button and offers additional tips for telephone equipment and accessories readers may find helpful. Finally, this article suggests guidelines for using an answering machine or voicemail system and provides a 25-question quiz to help readers assess their own telephone technique.

    2002-01-01

    Full Text Available The paper explores the possibilities of using telephone technology in educational process. It is emphasized how valuable audio-teleconference and tutorial teaching are by means of telephone technology but skepticism is also expressed concerning the possibilities of using this type of technology in our educational system. The causes for such skepticism are mostly to be found in our economic conditions, inadequacy of material sources and technical problems i.e. underdeveloped telephone networks. Telephone technology is not suitable for work with a whole class. It is primarily intended for one-to-one teaching, in the USA most often called 'tutorship'. Accordingly, 'telephone tutorship' is the most widespread form of telephone application in the teaching process. When it is being accomplished, a student (user has only to have a telephone at home or that public phone network is operating and he/she can communicate with his/her 'tutor', (teacher. 'A tutor' can be at home and communicate with his/her students or at a local learning center wherefrom he/she can communicate with a student. Students can also be at their local learning center or at home.

    2013-09-01

    Full Text Available Background. This study tested the hypothesis that data from random digit-dial telephone surveys underestimate the prevalence of cigarette smoking among African-American adults. Method. A novel, community-sampling method was used to obtain a statewide, random sample of N= 2118 California (CA African-American/Black adults, surveyed door-to-door. This Black community sample was compared to the Blacks in the CA Health Interview Survey (N = 2315, a statewide, random digit-dial telephone-survey conducted simultaneously. Results. Smoking prevalence was significantly higher among community (33% than among telephone-survey (19% Blacks, even after controlling for sample-differences in demographics.Conclusions. Telephone surveys underestimate smoking among African-Americans and probably underestimate other health risk behaviors as well. Alternative methods are needed to obtain accurate data on African-American health behaviors and on the magnitude of racial disparities in them.

    Directory of Open Access Journals (Sweden)

    David Malah

    2007-01-01

    Full Text Available A system for bandwidth extension of telephone speech, aided by data embedding, is presented. The proposed system uses the transmitted analog narrowband speech signal as a carrier of the side information needed to carry out the bandwidth extension. The upper band of the wideband speech is reconstructed at the receiving end from two components: a synthetic wideband excitation signal, generated from the narrowband telephone speech and a wideband spectral envelope, parametrically represented and transmitted as embedded data in the telephone speech. We propose a novel data embedding scheme, in which the scalar Costa scheme is combined with an auditory masking model allowing high rate transparent embedding, while maintaining a low bit error rate. The signal is transformed to the frequency domain via the discrete Hartley transform (DHT and is partitioned into subbands. Data is embedded in an adaptively chosen subset of subbands by modifying the DHT coefficients. In our simulations, high quality wideband speech was obtained from speech transmitted over a telephone line (characterized by spectral magnitude distortion, dispersion, and noise, in which side information data is transparently embedded at the rate of 600 information bits/second and with a bit error rate of approximately 3⋅10−4. In a listening test, the reconstructed wideband speech was preferred (at different degrees over conventional telephone speech in 92.5% of the test utterances.

  9. Can Smartphones Enhance Telephone-Based Cognitive Assessment (TBCA?

    Directory of Open Access Journals (Sweden)

    Rick Yiu-Cho Kwan

    2013-12-01

    Full Text Available TBCA has emerged to solve the limitations of administering cognitive assessments face-to-face. The recent development of telephones and knowledge advances in the area of cognitive impairment may affect the development of TBCA. The purpose of this paper is to discuss how smartphones can be used to enhance the applicability of TBCA, which has previously been administered by conventional telephone. This paper will first review, describe and critique the existing TBCA instruments. It will then discuss the recent developments in tele-technology, the popularity of tele-technology among the elderly, potential benefits and challenges in using smartphones for cognitive assessment, and possible future developments in this technology. In the systematic review, eighteen TBCA instruments were identified. They were found to be valid in differentiating between people with and without dementia. TBCA was previously found to be launched on a conventional telephone platform. The advances in understanding of cognitive impairment may demand that telephones be equipped with more advanced features. Recently, the development and penetration of smartphones among the elderly has been rapid. This may allow the smartphone to enhance its TBCA applicability by overcoming the limitations of the conventional telephone, rendering the TBCA more efficient in addressing the increasing demand and complexity of cognitive assessments in the future. However, more research and technology developments are needed before smartphones can become a valid platform for TBCA.

  10. Telephone management of poisonings using syrup of ipecac.

    1976-01-01

    Seven hundred and seventy-six cases were studied during a six-month period to see if induction of emesis could be successfully managed at home by telephone. Emesis was successful in 98.8% of cases. In 6.7% of all cases, symptoms were found at 4-hour follow-up that were referrable to the ingestion, but all were considered to be of minor consequence. No complications of vomiting occurred. Twenty-four hour follow-up investigation indicated no significant complications of induction of emesis or complications from managing the patient by telephone. It is our conclusion that, with appropriate telephone supervision, home-induced emesis of ingestions expected to produce mild to moderate symptoms is as effective as emergency room or physician office management of cases. Furthermore, the absence of adverse affects of complications arising from the induction of emesis at home in our cases confirms that this form of management is quite safe.

    Communication is commonly cited as a contributing factor to adverse events causing patient harm (Baker et al., 2004). There are numerous ways and reasons that communication failures can occur, such as poor handwriting, transcription errors, lack of verification, lack of integration of information, and ineffective team functioning. Errors that can occur in critical care with the verbal communication and receipt of a telephone order will be highlighted. These examples, together with proposed strategies for improving telephone order safety, are intended to promote awareness and potential practice changes in the critical care environment.

    Population studies often seek to examine phenomena in important population subgroups or to compare results among these and other subgroups. When subgroups of interest comprise a relatively small percentage of the population and acceptable subgroup member lists are not available to serve as sampling frames, it may be prohibitively expensive even by telephone to screen through a sample of the entire population. This paper considers some statistical effects of estimation from a class of two-stratum telephone sample designs where part of the frame with a higher subgroup concentration is disproportionately sampled compared to the rest of the frame. Using proportionate sampling as a reference, the relative impact of this disproportionate design is determined for nominal and effective sample sizes, where the latter are tied to the effect of variation in sample weights that occurs in disproportionately allocated samples. Findings are illustrated using two recent telephone surveys. Whereas nominal subgroup sample sizes may be improved by disproportionate sampling, we conclude that both the survey designer and analyst should use this type of design cautiously in telephone surveys.

    Although controversy still exists about dispensing medical advice over the telephone, such services are widely offered by pediatricians in the USA. In Israel, however, such services have not yet been developed. In a joint project of the Moked Keshev (a private medical help line) at Magen David Adom (national ambulance service) and the Children's Medical Center of Israel, the first pediatric telephone advice service in Israel was established. In this study we analyzed 512 consecutive incoming calls received during the first 11 months of service operation. Of these, 42% of calls concerned children in the 1 month to 1 year age group. Unexpectedly, calls were almost evenly distributed throughout the week with a slight decrease on Fridays and Saturdays (sabbath), and 45.7% of the calls were received during the morning shift. The three most common reasons for contact were: of a general nature such as fever (23%), gastrointestinal problems (19%), and medical questions (18%). In only 20.7% of the cases were the patients advised to go to the nearest hospital emergency department, emphasizing the non-emergent nature of the calls. At the time of follow-up (within 24 h), patient status was assessed as: improved (73.7%), same (22.6%), and worse (3.8%). Of those who became worse, none required an emergency department evaluation. The present study demonstrates that a Pediatric Telephone Advice Service in Israel is technically functional, medically safe, and contributes to the health management of children.

    Telephone reminder systems have been used to assist in the treatment of many chronic diseases. However, it is unclear if these systems can increase medication and appointment adherence in patients with diabetes without direct patient-provider telephone contact. We tested the feasibility of using an automated telephone reminder system (ATRS) to deliver reminder messages to 253 adults with diabetes enrolled in a randomized controlled trial. Eighty-four percent of the patients were able to register using voice recognition and at least one reminder was delivered to 95% of registered patients over a period of 7.5 months. None of the demographic features studied predicted a patient's ability to enroll or to receive reminder calls. At the end of the study, 63% of patients indicated that they wished to continue to receive ATRS calls. The level of system use as determined by the number of received reminder calls was not associated with a change in the number of physician visits or diabetes-related laboratory tests during follow-up. The clinical benefits and sustainability of ATRS remain unproven, but our results indicate that an automated reminder system can be effective for providing messages to a large group of older patients with diabetes.

    Mental health telephone help-lines usually play a significant role in mental health services system. Their importance is substantiated during periods of financial crisis, where the mental health of the population is gravely inflicted. Media reports have documented a large increase in calls made to mental health telephone help-lines around the world as a corollary to the global economic crisis; however, a systematic investigation of this observation is still lacking. In this context, the present study endeavours to fill this gap in the literature, while it adds strength to the handful of studies which have empirically supported the impact of the financial crisis on mental health in Greece. Data were extracted from information gleaned during the calls made to the Depression Telephone Helpline of the Greek University Mental Health Research Institute. The information entailed the reason for calling, the socio-demographic and clinical profile of the person with mental health problems, his/her previous and current contacts with mental health professionals and the treatment he/she might be receiving. The results showed a steep increase in calls with direct or indirect reference to the economic crisis during the first half of 2010 and onwards. The callers who referred to the economic crisis manifested depressive symptomatology of clinical significance to a greater degree than callers who made no such reference. The latter exhibited increased levels of distress and agitation as well as drug/alcohol misuse. Concomitantly, a higher frequency of depressive symptomatology was discerned among the unemployed, whereas employed people were found to experience anxiety symptoms to a higher degree. The impact of the financial crisis on the mental health of the Greek population has been considerable, underscoring in this way the importance of mental health help-lines as emotional buffers and as guides for timely and appropriate service use in response to the emerging mental health

  20. Ludvig Lorenz, Electromagnetism, and the Theory of Telephone Currents

    2016-01-01

    Ludvig V. Lorenz (1829-1891) was Denmark's first theoretical physicist and the only one whose work attracted international attention in the second half of the nineteenth century. This paper presents a survey of Lorenz's contributions to physics with an emphasis on his work in electrodynamics and electrical science. His 1867 electrodynamic theory of light was of a theoretical and foundational nature, while his unpublished theory of telephone currents was oriented toward practical problems in long-distance telephony. Lorenz's theories are briefly compared to those of better known physicists such as H. A. Lorentz, J. C. Maxwell, and O. Heaviside.

    The advent of mobile telephony and Voice over IP (VoIP) has significantly impacted the traditional telephone exchange industry—to such an extent that private branch exchanges are likely to disappear completely in the near future. For large organisations, such as CERN, it is important to be able to smooth this transition by implementing new multimedia platforms that can protect past investments and the flexibility needed to securely interconnect emerging VoIP solutions and forthcoming developments such as Voice over LTE (VoLTE). We present the results of ongoing studies and tests at CERN of the latest technologies in this area.

    Efficient systems to triage increasing numbers of new referrals to breast clinics are needed, to optimise the management of patients with cancer and benign disease. A tool was developed to triage the urgency of referrals and allocate the most appropriate clinician consultation (surgeon or breast physician (BP)). 259 consecutive new referrals were triaged using the tool. 100% new cancers and 256 (98.8%) referrals overall were triaged to both appropriate category of urgency and the appropriate clinician. This triage tool provides a simple method for assessing new referrals to a breast clinic and can be easily delivered by trained administrative staff by telephone.

    This article traces the experience of the first 2 years of managing the Solidarite SIDA toll-free telephone hotline service, including the services offered, the training needed for those answering the calls, statistics on those using the service, and the types of questions asked. SIDA was established in May 1996 as a support network. The goals of Solidarite SIDA have been encouraging contacts and the exchange of information; defending and promoting the rights and dignity of the people living with HIV and AIDS, their families, and friends; and sharing experiences with official organizations and other associations. The SOS AIDS telephone hotline was opened on December 1, 1996, to provide a sympathetic ear and to give information, advice and moral support to callers and to document the problems. Overall, it is noted that majority who utilize the services are young Melanesians who require information most often related to HIV transmission and its preventative measures. It is also indicated that the free phone is a source of advice and support with regard to worries connected to sexuality. In view of this, more advertising is necessary and documentation of calls should be continued in order to provide statistics to official institutions and other associations who work in HIV and AIDS. The expansion of the program is projected.

    ABSTRACT Objective: to test the effects of behavioral and educational intervention by telephone on adherence of women with inappropriate periodicity to colpocytological examination. Method: quasi-experimental study with a sample of 524 women, selected with the following inclusion criteria: be aged between 25 and 64 years, have initiated sexual activity, have inappropriate periodicity of examination and have mobile or landline phone. The women were divided into two groups for application of behavioral and educational intervention by telephone. It was used an intervention script according to the principles of Motivational Interviewing. Results: on comparing the results before and after the behavioral and educational interventions, it was found that there was a statistically significant change (p = 0.0283) with increase of knowledge of women who participated in the educational intervention. There was no change in the attitude of women of any of the groups and there was an increase of adherence to colpocytological examination in both groups (p < 0.0001), with greater adherence of women participating in the behavioral group (66.8%). Conclusion: the behavioral and educational interventions by phone were effective in the adherence of women to colpocytological examination, representing important strategies for permanent health education and promotion of care for the prevention of cervical cancer.

    Full Text Available Abstract Background Non-coverage of households without a landline telephone is a major concern of telephone survey researchers. Sampling mobile telephone users in national surveys is vital in order to gain access to the growing proportion of households that use mobile telephones extensively or exclusively. The complex logistics of conducting surveys with mobile telephones have been discussed in the literature. This paper outlines the actual challenges encountered during a recent national sexual health survey in Ireland, which utilized a mobile telephone sampling frame to recruit approximately half of the sample. Method The 2010 Irish Contraception and Crisis Pregnancy Survey (ICCP-2010 is a nationally representative sample of adults aged 18-45 years living in Ireland (n = 3002; 1416 recruited by landline telephone and 1586 recruited by mobile telephone. The overall response rate for the survey was 69% (79% for the landline telephone strand; 61% for the mobile telephone strand. All interviews were conducted using computer-assisting telephone interviewing. Results During the 18-week fieldwork period, five main challenges relating to the use of mobile telephones were encountered: (1 explaining to respondents how random digit dialling works in relation to mobile telephones; (2 establishing the respondent's eligibility; (3 calling the respondent with the Caller ID blocked or withheld; (4 calling the respondent when they are in any number of locations or situations; and (5 explaining to respondents the importance of refusal conversion calls for the response rate calculation. Details of how the survey protocols and procedures were monitored and adapted throughout the study to ensure a high response rate are outlined. Conclusion It is undeniably more challenging to recruit respondents using mobile telephones as opposed to landline telephones. Respondents are generally not familiar with being contacted on their personal mobile telephone for the purposes

    2016-01-01

    Evidence from human medicine shows a rise in telephone communication in support of after-hours services and in providing medical advice, follow-up information, etc. While specific training programs are continuously being developed for human medical education, limited publications are available on training veterinary students in telephone communication. Presented is our method of introducing a telephone communication skills exercise to third-year veterinary students. The exercise progressed over three phases and currently follows the principles of the Calgary-Cambridge Guide. Challenges and improvements on implementing a telephone communication exercise are discussed. Within veterinary communication curricula, attention should be given to the specific communication skills required for successful telephone consultations. In the absence of visual nonverbal cues and prompts during a telephone interaction, communication skills must be applied with greater intent and attention to achieve an effective consultation outcome.

    Dengineer Co., Ltd. and Buyo Gas Co., Ltd. had been developing and using the data and alarm transmission system by public telephone since 1984, that was first practical use in Japan. It is very important for business management that adjusts the production value of gas by measuring gas pressures in each governor. Also, it is indispensable to know the accident of gas leakage or abnormal gas pressure quickly. But this convenient system is not spread yet in Japanese market cause of the following reasons. - Take time and cost for installation of terminal station. - Terminal station is apt to damage by thunder. - Big disaster must stop working this system. In order to solve those problems, we have developed and tested the system organized of the satellite telephone system and solar cells for power. This system will be very useful for wide place, not only Japanese market but also the area, which has no electricity and phone. Also, it will be convenient for international rescue as is able to access it from the foreign countries. (authors)

    Full Text Available Hilde Kristin Brekke, Åsa Sunesson, Ragnhild A LennerDepartment of Clinical Nutrition, Sahlgrenska Academy at the University of Gothenburg, Gothenburg, SwedenObjectives: Reinforcement is critical in dietary counseling, but is also time demanding. We evaluated the acceptability of frequent telephone interviews, including a 24-hour dietary recall, as a means of reinforcement after lifestyle intervention in healthy subjects at risk of diabetes. The aim of this report is to assess the following questions: Was the chosen frequency and duration of telephone reinforcement appropriate? What were the positive and negative aspects of receiving telephone interviews?Methods: Seventy-seven nondiabetic relatives of patients with type 2 diabetes were included in a randomized controlled intervention study in which they received dietary education. Unannounced telephone calls were placed to follow adherence and for encouragement and support. After two years of intervention, the perceived appropriateness of the different aspects of receiving telephone interviews were evaluated by postal questionnaire.Results: Telephone reinforcement was positively received by the participants. Relatively frequent telephone calls, as many as three times per month, were not considered disturbing or time consuming. Participants became aware of their own dietary habits through the interviews, which they appreciated. They found duration of follow-up between one and five years appropriate.Conclusions: Telephone interviews can be applied in lifestyle intervention programs in healthy at-risk individuals in which time constraints may otherwise prevent active persons from participating.Keywords: telephone interviews, reinforcement, lifestyle, intervention, acceptability

    2010-01-01

    Service members who have had a traumatic brain injury (TBI) in a war theatre [Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF)] may have associated injuries far different and/or more complex (i.e., polytrauma) than injuries obtained outside the theatre of operation. This article expands on what has been learned from monitoring patients injured during peacetime to the newly injured war veterans being monitored in the home setting via routine telephonic follow-up. As Tanielian et al. state TBI, post traumatic stress disorder (PTSD) and major depression may occur during and following deployment/s which then pose a significant health risk to these veterans. This is particularly important as veterans of these two conflicts may incur these "invisible wounds of war". Thus, safe and effective monitoring of these veterans by nurses/case managers in the home/community setting becomes important in the recovery process.

    2014-01-01

    Full Text Available Objective: Nurse-led telephone follow-up is effective in meeting information and psycho-social needs. We explored the potential effects of nurse-led telephone follow-up for patients treated with chemotherapy in China. Methods: A quasi-experimental study was employed in the research. 300 cases of cancer inpatients in a cancer hospital in Beijing during July-October 2012 were selected by convenience sampling. To compare the satisfaction and response regarding to chemotherapy adverse side effects, patients who discharged on Monday and Friday were provided with telephone follow-up. Patients who discharged on Tuesday, Wednesday and Thursday received routine care. Results: Via telephone follow-up, patient satisfaction relating to nursing care increased. Moreover, their response to chemotherapy adverse side effects showed a significant difference. Conclusion: Telephone follow-up by specialist nurses may be a feasible option. It was well received by patients, with no physical or psychological disadvantage.

    Public relations activities of the German Research Network on Schizophrenia (GRNS) have shown that there is a demand for more information about schizophrenia disorder. This confirms international research findings that relatives of schizophrenia patients are particularly in need of information and support. In response, the GRNS has maintained a telephone hotline since 2001. The hotline is manned by clinical experts, psychiatrists, or psychologists once a week. The telephone calls are documented in a systematic manner. From 2001 to 2003, 3,909 calls were registered. This volume exceeds the limit of the hotline's resources. The telephone hotline is mainly used by relatives of psychotic patients. Most questions relate to the symptoms of schizophrenia and pharmaceutical treatment. The need for emotional support is also a high motivational factor for dialing the hotline number. The telephone hotline seems to be a worthwhile addition to the already existing crisis telephones and should be maintained even after public funding of the network expires.

  16. Using Developmental Theory: When Not to Play Telephone Games

    Directory of Open Access Journals (Sweden)

    Sara Nora Ross

    2008-06-01

    Full Text Available As a powerful way to help understand the behaviors of people and socialgroupings of all kinds, developmental stage theory attracts attention and use outside ofpurely academic environments. These uses take the form of written materials and manykinds of interventions. The level of accuracy of developmental theory informationgenerated and used outside of academe demonstrates wide variety. This variety isreflected in materials and interventions. The information used in materials andinterventions becomes increasingly distorted as it becomes further removed from originaltheoretical sources. This has major implications for the ethics and expertise issues that areinherent in applied developmental theory. A classification scheme of information-usebehaviors, many of which contribute to distortion processes, is used to code actual casesof creating and disseminating distorted developmental theory information, invoking themetaphor of telephone games. Case evidence indicates that casual, illustrative figures in a2006 book by Wilber were used by others for various serious and theoretical purposes,and resulted in major distortions of developmental theory. Wilber’s figures representproblematic issues and errors, including distortion of theory, if they are used—as theyindeed were—for any purpose more serious than his original purpose. Stemming fromthose issues and errors, a highly distorted picture of cognitive development and a pseudoversionof Commons and Richards’ Model of Hierarchical Complexity theory emerged,telephone game-like, in the cases discussed. Errors were widely propagated on theinternet. Because outside of academe, specialized expertise in developmental theory isdifficult to acquire, the sub-field of applied developmental theory requires not onlyaccurate information but also strong communication ethics to govern behaviors ofinformation providers. Such providers need to protect themselves at the same time theyprotect and inform consumers of

  17. Analyzing online sentiment to predict telephone poll results.

    Fu, King-wa; Chan, Chee-hon

    2013-09-01

    The telephone survey is a common social science research method for capturing public opinion, for example, an individual's values or attitudes, or the government's approval rating. However, reducing domestic landline usage, increasing nonresponse rate, and suffering from response bias of the interviewee's self-reported data pose methodological challenges to such an approach. Because of the labor cost of administration, a phone survey is often conducted on a biweekly or monthly basis, and therefore a daily reflection of public opinion is usually not available. Recently, online sentiment analysis of user-generated content has been deployed to predict public opinion and human behavior. However, its overall effectiveness remains uncertain. This study seeks to examine the temporal association between online sentiment reflected in social media content and phone survey poll results in Hong Kong. Specifically, it aims to find the extent to which online sentiment can predict phone survey results. Using autoregressive integrated moving average time-series analysis, this study suggested that online sentiment scores can lead phone survey results by about 8-15 days, and their correlation coefficients were about 0.16. The finding is significant to the study of social media in social science research, because it supports the conclusion that daily sentiment observed in social media content can serve as a leading predictor for phone survey results, keeping as much as 2 weeks ahead of the monthly announcement of opinion polls. We also discuss the practical and theoretical implications of this study.

    Critics of public opinion polls often claim that methodological shortcuts taken to collect timely data produce biased results. This study compares two random digit dial national telephone surveys that used identical questionnaires but very different levels of effort: a "Standard" survey conducted over a 5-day period that used a sample of adults who were home when the interviewer called, and a "Rigorous" survey conducted over an 8-week period that used random selection from among all adult household members. Response rates, computed according to AAPOR guidelines, were 60.6 percent for the Rigorous and 36.0 percent for the Standard study. Nonetheless, the two surveys produced similar results. Across 91 comparisons, no difference exceeded 9 percentage points, and the average difference was about 2 percentage points. Most of the statistically significant differences were among demographic items. Very few significant differences were found on attention to media and engagement in politics, social trust and connectedness, and most social and political attitudes, including even those toward surveys.

  19. A tool for hearing aid and cochlear implant users to judge the usability of cellular telephones in field conditions

    Science.gov (United States)

    Deer, Maria Soledad

    The auditory experience of using a hearing aid or a cochlear implant simultaneously with a cell phone is driven by a number of factors. These factors are: radiofrequency and baseband interference, speech intelligibility, sound quality, handset design, volume control and signal strength. The purpose of this study was to develop a tool to be used by hearing aid and cochlear implant users in retail stores as they try cell phones before buying them. This tool is meant to be an efficient, practical and systematic consumer selection tool that will capture and document information on all the domains that play a role in the auditory experience of using a cell phone with a hearing aid or cochlear implant. The development of this consumer tool involved three steps as follows: preparation, verification and measurement of success according to a predefined criterion. First, the consumer tool, consisting of a comparison chart and speech material, was prepared. Second, the consumer tool was evaluated by groups of subjects in a two-step verification process. Phase I was conducted in a controlled setting and it was followed by Phase II which took place in real world (field) conditions. In order to perform a systematic evaluation of the consumer tool two questionnaires were developed: one questionnaire for each phase. Both questionnaires involved five quantitative variables scored with the use of ratings scales. These ratings were averaged yielding an Overall Consumer Performance Score. A qualitative performance category corresponding to the Mean Opinion Score (MOS) was allocated to each final score within a scale ranging from 1 to 5 (where 5 = excellent and 1 = bad). Finally, the consumer tool development was determined to be successful if at least 80% of the participants in verification Phase II rated the comparison chart as excellent or good according to the qualitative MOS score. The results for verification Phase II (field conditions) indicated that the Overall Consumer Performance score for 92% of the subjects (11/12) was 3.7 and above corresponding to Good and Excellent MOS qualitative categories. It was concluded that this is a practical and efficient tool for hearing aid/cochlear implant users as they approach a cell phone selection process.

    The effects of continuous exposure of chick embryos and young chickens to the electromagnetic fields (EMFs) emitted by video display units (VDUs) and GSM cell phone radiation, either the whole spectrum emitted or attenuated by a copper gauze, were investigated. Permanent exposure to the EMFs radiated by a VDU was associated with significantly increased fetal loss (47-68%) and markedly depressed levels of circulating specific antibodies (lgG), corticosterone and melatonin. We have also shown that under chronic exposure conditions, GSM cell phone radiation was harmful to chick embryos, stressful for healthy mice and, in this species, synergistic with cancer insofar as it depleted stress hormones. The same pathological results were observed after substantial reduction of the microwaves radiated from the cell phone by attenuating them with a copper gauze. (author)

    2007-01-01

    The telephone and the internet have become popular sources of psychological help in various types of distress, including a suicide crisis. To gain more insight into the unique features of these media, we compared characteristics of calls to three technologically mediated sources of help that are part of the volunteer-based Israeli Association for Emotional First Aid (ERAN): Telephonic hotline (n = 4426), personal chat (n = 373) and an asynchronous online support group (n = 954). Threats of suicide were much more frequent among participants in the asynchronous support group than the telephone and personal chat. These findings encourage further research into suicide-related interpersonal exchanges in asynchronous online support groups.

    1998-01-01

    This paper describes a new interview data collection system that uses a personal computer equipped with a telephone interface card. This system, telephone audio computer-assisted self-interviewing or T-ACASI, offers the economy of telephone interviews while providing the privacy of self-administered questionnaires. We describe T-ACASI design considerations and operational characteristics. In addition, we present data from recent studies indicating that the T-ACASI system is stable, robust, and suitable for administering relatively long and complex questionnaires on sensitive topics, including drug use and sexual behaviors associated with HIV and other STDs.

    Dropout from outpatient mental health treatment may contribute to high rates of relapse and rehospitalization among veterans with chronic posttraumatic stress disorder (PTSD). In a quasi-experimental cohort study, 87 male and 17 female veterans discharging from residential PTSD treatment received either standard referral to outpatient care (N = 77) or standard referrals supplemented by biweekly telephone calls (N = 27). Telephone monitoring and support was feasible and acceptable to 85% of clients. Compared to prior patient cohorts, clients receiving telephone support were twice as likely (88% vs. 43%) to complete an outpatient visit within 1 month of discharge and reported higher satisfaction with care.

  5. Is web interviewing a good alternative to telephone interviewing? Findings from the International Tobacco Control (ITC Netherlands Survey

    Directory of Open Access Journals (Sweden)

    Thompson Mary E

    2010-06-01

    Full Text Available Abstract Background Web interviewing is becoming increasingly popular worldwide, because it has several advantages over telephone interviewing such as lower costs and shorter fieldwork periods. However, there are also concerns about data quality of web surveys. The aim of this study was to compare the International Tobacco Control (ITC Netherlands web and telephone samples on demographic and smoking related variables to assess differences in data quality. Methods Wave 1 of the ITC Netherlands Survey was completed by 1,668 web respondents and 404 telephone respondents of 18 years and older. The two surveys were conducted in parallel among adults who reported smoking at least monthly and had smoked at least 100 cigarettes over their lifetime. Results Both the web and telephone survey had a cooperation rate of 78%. Web respondents with a fixed line telephone were significantly more often married, had a lower educational level, and were older than web respondents without a fixed line telephone. Telephone respondents with internet access were significantly more often married, had a higher educational level, and were younger than telephone respondents without internet. Web respondents were significantly less often married and lower educated than the Dutch population of smokers. Telephone respondents were significantly less often married and higher educated than the Dutch population of smokers. Web respondents used the "don't know" options more often than telephone respondents. Telephone respondents were somewhat more negative about smoking, had less intention to quit smoking, and had more self efficacy for quitting. The known association between educational level and self efficacy was present only in the web survey. Conclusions Differences between the web and telephone sample were present, but the differences were small and not consistently favourable for either web or telephone interviewing. Our study findings suggested sometimes a better data

  11. Telephone speech enhancement for hearing-impaired listeners using multi-channel compression

    Science.gov (United States)

    Natarajan, Harikrishna P.; Krishnamurthy, Ashok K.; Feth, Lawrence L.

    2002-05-01

    Elderly listeners with sensorineural hearing impairment usually have difficulty with telephone communication if they do not use a hearing aid or telephone amplifier. In many cases, these devices may not be readily available or maybe uncomfortable to use. We describe here an alternative strategy to enhance the speech by pre-processing the signal before sending it over the telephone line. The pre-processing is based on a multi-channel compression algorithm that modifies the critical band spectrum of the speech signal to bring it within the dynamic hearing range of the listener, while also compensating for the effects of the telephone line. We describe the algorithm and the results of a simulation study in which the Articulation Index (AI) is used to measure the intelligibility enhancement, and the Glasberg, Moore and Stone (1999) model is used to simulate the effects of the hearing loss.

    2008-01-01

    The effectiveness of a cognitive behavioural bibliotherapy self-help package, with varied levels of telephone support, delivered through a mental health telephone service was examined with 84 mildly to moderately depressed adults. The study compared the changes in depressive symptoms of three groups: control, self help with minimal contact and self-help with telephone assistance. Both the minimal contact and the assisted self-help groups had significant reductions in their levels of depression compared with the control group. Treatment gains were maintained at a 1-month follow-up. The potential of self-help resources such as this to be successfully disseminated and delivered through a national mental health telephone information service is discussed.

    Abide by the design principles of mine intrinsically safe circuit, according to the need of underground communication in coal mine, the paper proposed a design scheme of DC carrier telephone which can dial. The design circuit of the telephone is introduced in detail. The telephone's voice signals are generated by the microphone. After enlarged then the voice signals are modulated to frequency signals by LM567 chip. The frequency signals are coupled by transformer and then transmitted by 12V DC power supply line to the other voice terminals. In the voice terminal the signals are demodulated by LM567 demodulation circuit and enlarged by LM386, then, the amplified audio signals are output from a speaker. The dialing circuit is designed based on the STM32 MCU. The dial information is transmitted to the other telephone terminals by CAN bus. The measured distance calls is greater than 2000m, volume is larger than 85dB, good results.

  16. Reversible quantum cellular automata

    CERN Document Server

    Schumacher, B

    2004-01-01

    We define quantum cellular automata as infinite quantum lattice systems with discrete time dynamics, such that the time step commutes with lattice translations and has strictly finite propagation speed. In contrast to earlier definitions this allows us to give an explicit characterization of all local rules generating such automata. The same local rules also generate the global time step for automata with periodic boundary conditions. Our main structure theorem asserts that any quantum cellular automaton is structurally reversible, i.e., that it can be obtained by applying two blockwise unitary operations in a generalized Margolus partitioning scheme. This implies that, in contrast to the classical case, the inverse of a nearest neighbor quantum cellular automaton is again a nearest neighbor automaton. We present several construction methods for quantum cellular automata, based on unitaries commuting with their translates, on the quantization of (arbitrary) reversible classical cellular automata, on quantum c...

  17. Telephone versus office-based management of warfarin: impact on international normalized ratios and outcomes.

    Science.gov (United States)

    Stoudenmire, Laura G; DeRemer, Christina E; Elewa, Hazem

    2014-08-01

    Studies have concluded that telephone-based management of warfarin is an effective alternative to in-office management. High rates of patient and physician satisfaction have been reported with telephone-based monitoring. Proposed benefits of telephone-based monitoring include time- and cost savings for patients and healthcare providers alike as well as increased access to care for those patients who have difficulty making in-office appointments. This study aimed to evaluate the impact of telephone versus office-based management of warfarin on extreme INR values. A retrospective cohort study was conducted to assess outcomes of patients receiving warfarin managed either by telephone or in-office appointments. The primary endpoint of the study was the frequency of extreme INR values, defined as an INR ≤1.5 or ≥4.5. A total of 110 patients were evaluated; subjects were distributed 2:1 between the in-office and telephone groups. Baseline characteristics were similar between groups. Subjects followed via telephone had a twofold increase in the incidence of extreme INR values compared to the patients followed in-office (15.18 vs. 7.98 %; p < 0.0001). Overall TTR was similar between groups (85.39 vs. 80.38 %, p = 0.1171). There was no difference between the two groups in the incidence of major bleeding events (2.67 vs. 0 %, p = 1.00), thromboembolic events (8 vs. 0 %, p = 0.1740), or hospitalizations related to anticoagulation therapy (6.67 vs. 0 %, p = 0.1758). Patients monitored via telephone had a higher incidence of extreme INR values than patients followed in-office, which may lead to an increased incidence of adverse outcomes in the long-term. Well-designed, prospective studies are needed to confirm such findings.

    Full Text Available Abstract Background Quantitative Microbial Risk Assessment (QMRA, a modelling approach, is used to assess health risks. Inputs into the QMRA process include data that characterise the intensity, frequency and duration of exposure to risk(s. Data gaps for water exposure assessment include the duration and frequency of urban non-potable (non-drinking water use. The primary objective of this study was to compare household water usage results obtained using two data collection tools, a computer assisted telephone interview (CATI and a 7-day water activity diary, in order to assess the effect of different methodological survey approaches on derived exposure estimates. Costs and logistical aspects of each data collection tool were also examined. Methods A total of 232 households in an Australian dual reticulation scheme (where households are supplied with two grades of water through separate pipe networks were surveyed about their water usage using both a CATI and a 7-day diary. Householders were questioned about their use of recycled water for toilet flushing, garden watering and other outdoor activities. Householders were also questioned about their water use in the laundry. Agreement between reported CATI and diary water usage responses was assessed. Results Results of this study showed that the level of agreement between CATI and diary responses was greater for more frequent water-related activities except toilet flushing and for those activities where standard durations or settings were employed. In addition, this study showed that the unit cost of diary administration was greater than for the CATI, excluding consideration of the initial selection and recruitment steps. Conclusion This study showed that it is possible to successfully 'remotely' coordinate diary completion providing that adequate instructions are given and that diary recording forms are well designed. In addition, good diary return rates can be achieved using a monetary incentive

    Au nanocrystals spin-coated onto silicon from toluene form cellular networks. A quantitative statistical crystallography analysis shows that intercellular correlations drive the networks far from statistical equilibrium. Spin-coating from hexane does not produce cellular structure, yet a strong correlation is retained in the positions of nanocrystal aggregates. Mechanisms based on Marangoni convection alone cannot account for the variety of patterns observed, and we argue that spinodal decomposition plays an important role in foam formation.

  4. Epigenetics and Cellular Metabolism

    2016-01-01

    Living eukaryotic systems evolve delicate cellular mechanisms for responding to various environmental signals. Among them, epigenetic machinery (DNA methylation, histone modifications, microRNAs, etc.) is the hub in transducing external stimuli into transcriptional response. Emerging evidence reveals the concept that epigenetic signatures are essential for the proper maintenance of cellular metabolism. On the other hand, the metabolite, a main environmental input, can also influence the processing of epigenetic memory. Here, we summarize the recent research progress in the epigenetic regulation of cellular metabolism and discuss how the dysfunction of epigenetic machineries influences the development of metabolic disorders such as diabetes and obesity; then, we focus on discussing the notion that manipulating metabolites, the fuel of cell metabolism, can function as a strategy for interfering epigenetic machinery and its related disease progression as well.

    2016-07-01

    Additive manufacturing enables fabrication of materials with intricate cellular architecture, whereby progress in 3D printing techniques is increasing the possible configurations of voids and solids ad infinitum. Examples are microlattices with graded porosity and truss structures optimized for specific loading conditions. The cellular architecture determines the mechanical properties and density of these materials and can influence a wide range of other properties, e.g., acoustic, thermal, and biological properties. By combining optimized cellular architectures with high-performance metals and ceramics, several lightweight materials that exhibit strength and stiffness previously unachievable at low densities were recently demonstrated. This review introduces the field of architected materials; summarizes the most common fabrication methods, with an emphasis on additive manufacturing; and discusses recent progress in the development of architected materials. The review also discusses important applications, including lightweight structures, energy absorption, metamaterials, thermal management, and bioscaffolds.

  6. Public expectations of health professionals when patients telephone for medical advice.

    Science.gov (United States)

    Smith, Saxon; Werren, Julia

    2008-08-01

    This article focuses on the ethical, social and liability implications of patients obtaining unsolicited medical advice over the phone. The ethical discussion centres on the demise of paternalism and the increase in patient autonomy and individualism and the growing public expectations of health professionals. The article then discusses the advantages and disadvantages of telephone consultations from a social and policy perspective. In light of these considerations it considers what the liability implications are for phone consultations. It argues that the ethic of individualism, coupled with recent Australian tort reforms, suggests that only in limited circumstances would a doctor be found liable for negligence in relation to telephone consultations. However, the increasing expectations being placed on medical personnel, as evidenced by the increase in unsolicited telephone consultations, if left untempered, may lead to a situation with which the health care system is ill equipped to deal.

    1999-02-01

    Automated patient education and counseling over the telephone is a convenient and inexpensive method for modifying health-related behaviors. A computer-controlled, telecommunications technology called Telephone-Linked Care (TLC) was used to develop a behavioral intervention to assist smokers to quit and to prevent relapse. The education and counseling is offered through a series of interactive telephone conversations which can take place in the smoker's home. The system's automated dialogues are driven by an expert system that controls the logic. The content is derived from the Transtheoretical Model of behavioral change, principles of Social Cognitive Theory, strategies of patient-centered counseling and recommendations of clinical experts in smoking cessation. The system asks questions, provides information, gives positive reinforcement and feedback, and makes suggestions for behavioral change. Information that the patient communicates is stored and is used to influence the content of subsequent conversations.

    Full Text Available In the field of communication studies, the topic of telephony and the gendering of space via voice and emotions has received limited attention. The focus of this article is how telephone conversations are mediated by voice and emotions, which in turn shape and gender social space. The methodology is a collaborative autoethnographic design based on diary notes and memory work. Two central themes emerge from the findings that explain how space becomes gendered when using the telephone: (a the voice and relations of power, and (b the interstices between work, caring, and the telephone. Our findings reveal the central role of work and caring and how these spaces constantly are being traversed and transformed as the mobile phone becomes an important appendage for sensory perceptions of hearing/listening/voice. We argue that these themes point toward the crucial impact of emotions in the construction of multiple and gendered spatialities of telephony.

    2011-06-01

    Full Text Available Abstract Background The Community Reintegration of Service Members (CRIS is a new measure of community reintegration developed to measure veteran's participation in life roles. It consists of three sub-scales: Extent of Participation (Extent, Perceived Limitations with Participation (Perceived, and Satisfaction with Participation (Satisfaction. Testing of the CRIS measure to date has utilized in-person administration. Administration of the CRIS measure by telephone, if equivalent to in-person administration, would be desirable to lower cost and decrease administrative burden. The purpose of this study was to test the equivalence of telephone and in-person mode of CRIS administration. Methods A convenience sample of 102 subjects (76% male, 24% female, age mean = 49 years, standard deviation = 8.3 were randomly assigned to received either telephone interview at Visit 1 and in-person interview at Visit 2, or in-person interview at Visit 1 and telephone interview a Visit 2. Both Visits were conducted within one week. Intraclass correlation coefficients, ICC (2,1, were used to evaluate correspondence between modes for both item scores and summary scores. ANOVAs with mode order as a covariate were used to test for presence of an ordering effect. Results ICCs (95%CI for the subscales were 0.92 (0.88-0.94 for Extent, 0.85 (0.80-0.90 for Perceived, and 0.89 (0.84-0.93 for Satisfaction. No ordering effect was observed. Conclusion Telephone administration of the CRIS measure yielded equivalent results to in-person administration. Telephone administration of the CRIS may enable lower costs of administration and greater adoption.

    Gray, R T

    2012-02-01

    INTRODUCTION: Patients undergoing selective minor emergency and elective procedures are followed up by a nurse-led structured telephone review six weeks post-operatively in our hospital. Our study objectives were to review patients\\' satisfaction, assess cost-effectiveness and compare our practice with other surgical units in Northern Ireland (NI). PATIENTS AND METHODS: Completed telephone follow-up forms were reviewed retrospectively for a three-year period and cost savings calculated. Fifty patients were contacted prospectively by telephone using a questionnaire to assess satisfaction of this follow-up. A postal questionnaire was sent to 68 general and vascular surgeons in NI, assessing individual preferences for patient follow-up. RESULTS: A total of 1378 patients received a telephone review from September 2005 to September 2008. One thousand one hundred and seventy-seven (85.4%) were successfully contacted, while 201 (14.6%) did not respond despite multiple attempts. One hundred and forty-seven respondents (10.7%) required further outpatient follow-up, thereby saving 1231 outpatient reviews, equivalent to pound41,509 per annum. Thirty-nine (78%) patients expected post-operative follow-up, with 29 (58%) expecting this in the outpatient department. However, all patients were satisfied with the nurse-led telephone review. Fifty-three (78%) consultants responded. Those who always, or occasionally, review patients post-operatively varies according to the operation performed, ranging from 2.2% appendicectomy patients to 40.0% for varicose vein surgery. CONCLUSION: Current practice in NI varies, but a significant proportion of patients are not routinely reviewed. This study confirmed that patients expect post-operative follow-up. A nurse-led telephone review service is acceptable to patients, cost-effective and reduces the number of unnecessary outpatient reviews.

    Full Text Available Abstract Background Current frequent follow-up after treatment for breast cancer does not meet its intended aims, but does depend on expensive and scarce specialized knowledge for routine history taking and physical examinations. The study described in this paper compared patient satisfaction with a reduced follow-up strategy, i.e. nurse-led telephone follow-up, to satisfaction with traditional hospital follow-up. Methods Patient satisfaction was assessed among patients (n = 299 who were participants of a randomized controlled trial investigating the cost-effectiveness of several follow-up strategies in the first year after treatment for breast cancer. Data on patient satisfaction were collected at baseline, three, six and 12 months after treatment, using the Dutch version of Ware's Patient Satisfaction Questionnaire III (PSQ III. In addition to general satisfaction, the PSQ III reports on satisfaction scores for technical competence, interpersonal aspects, and access of care. Regression analysis was used to predict satisfaction scores from whether or not nurse-led telephone follow-up was received. Results Nurse-led telephone follow-up had no statistically significant influence on general patient satisfaction (p = 0.379, satisfaction with technical competence (p = 0.249, and satisfaction with interpersonal aspects (p = 0.662. Regarding access of care, patient satisfaction scores were significantly higher for patients receiving telephone follow-up (p = 0.015. However, a mean difference at 12 months of 3.1 points was judged to be not clinically relevant. Conclusions No meaningful differences were found in satisfaction scores between nurse-led telephone and hospital follow-up in the first year after breast cancer treatment. With high satisfaction scores and the potential to substantially reduce clinic visits, nurse-led telephone follow-up may be an acceptable alternative to traditional hospital follow-up.

    Full Text Available Cellular communications has experienced explosive growth in the past two decades. Today millions of people around the world use cellular phones. Cellular phones allow a person to make or receive a call from almost anywhere. Likewise, a person is allowed to continue the phone conversation while on the move. Cellular communications is supported by an infrastructure called a cellular network, which integrates cellular phones into the public switched telephone network. The cellular network has gone through three generations.The first generation of cellular networks is analog in nature. To accommodate more cellular phone subscribers, digital TDMA (time division multiple access and CDMA (code division multiple access technologies are used in the second generation (2G to increase the network capacity. With digital technologies, digitized voice can be coded and encrypted. Therefore, the 2G cellular network is also more secure. The third generation (3G integrates cellular phones into the Internet world by providing highspeed packet-switching data transmission in addition to circuit-switching voice transmission. The 3G cellular networks have been deployed in some parts of Asia, Europe, and the United States since 2002 and will be widely deployed in the coming years. The high increase in traffic and data rate for future generations of mobile communication systems, with simultaneous requirement for reduced power consumption, makes Multihop Cellular Networks (MCNs an attractive technology. To exploit the potentials of MCNs a new network paradigm is proposed in this paper. In addition, a novel sequential genetic algorithm (SGA is proposed as a heuristic approximation to reconfigure the optimum relaying topology as the network traffic changes. Network coding is used to combine the uplink and downlink transmissions, and incorporate it into the optimum bidirectional relaying with ICI awareness. Numerical results have shown that the algorithms suggested in this

    Nurses in a hematology/oncology practice are responsible for the triage and management of phone calls from a diverse oncology population. An initiative was developed at the authors' institution to identify the educational needs of RNs while designing strategies to educate and improve telephone triage skills. The goal was to standardize triage practice and ultimately improve the effectiveness of telephone triage management. It was felt that these improvements could enhance the nurse-patient relationship, resulting in continuity of care to the patient, as well as reducing inappropriate appointments and hospitalizations, enhancing education, and lessening the risk of medical complications related to delays in care.

    Language barriers in the care for patients with limited German language proficiency contribute to impaired quality of care, more frequent medical errors and decreased patient satisfaction. However, professional interpreters are not systematically used in Germany. We conducted a pilot study in a German paediatric hospital to explore the demand for an interpreter by conducting a survey among parents and to test the use of telephone interpreters. Eight percent of the respondents said they were interested in interpreter support. All physicians and parents using a telephone interpreter were very satisfied with the quality and the organisation of the service.

    Homeostasis is a term that refers to constancy in a system. A cell in homeostasis normally functions. There are two kinds of processes in the internal environment and external environment of a cell, the pathogenic processes (PP) which disrupts the old homeostasis (OH), and the sanogenetic processes (SP) which restores OH or establishes a new homeostasis (NH). Photobiomodualtion (PBM), the cell-specific effects of low intensity monochromatic light or low intensity laser irradiation (LIL) on biological systems, is a kind of modulation on PP or SP so that there is no PBM on a cell in homeostasis. There are two kinds of pathways mediating PBM, the membrane endogenetic chromophores mediating pathways which often act through reactive oxygen species, and membrane proteins mediating pathways which often enhance cellular SP so that it might be called cellular rehabilitation. The cellular rehabilitation of PBM will be discussed in this paper. It is concluded that PBM might modulate the disruption of cellular homeostasis induced by pathogenic factors such as toxin until OH has been restored or NH has been established, but can not change homeostatic processes from one to another one.

    Mupparapu, Muralidhar

    2008-03-01

    Voice over Internet protocol (VoIP) is a revolutionary new technology that is causing a stir in the telecommunications industry and threatening the existence of traditional telephone service providers. Based on a simple method of converting analog audio signals into digital data before being transmitted over the Internet, VoIP has gained immense popularity among consumers. The technology is now regarded as an alternative to traditional telephone service for the orthodontic office. When the economics are considered, it is cost-effective, especially for a busy orthodontic practice where the call volumes both in and out are always high. VoIP has the potential to reduce costs, break the barriers between local vs long-distance calling, and make life easier for the office staff. However, deploying VoIP requires a cautious and thought-out process. Users should fully understand the risks and benefits before switching from the public switched telephone network. VoIP customers and service providers are vulnerable to many of the same impersonation-based attacks by those who attempt toll fraud, and identity and information theft. In this article, VoIP is introduced to orthodontic practitioners, who might be unfamiliar with this technology. Internet protocol based private branch exchange systems that are currently marketed as open-source technologies are also reviewed. Additionally, VoIP is compared with the traditional public switched telephone network technology and evaluated for its potential applications in an orthodontic office for both increased efficiency and cost savings.

    Family caregivers of individuals with dementia are at heightened risk for emotional and mental health problems. Many caregivers do not seek assistance or become isolated in their caregiving role. Multi-component interventions have demonstrated efficacy for reducing emotional distress and burden, although these approaches are potentially costly and are not widely accessible. In response to these issues, we developed the Family Intervention: Telephone Tracking - Caregiver (FITT-C), which is an entirely telephone-based psychosocial intervention. The purpose of this paper is to describe the study design, methodology, and baseline data for the trial. This study uses a randomized controlled trial design to examine the efficacy of the FITT-C to reduce depressive symptoms and burden in distressed dementia caregivers. All participants (n=250) received a packet of educational materials and were randomly assigned to receive 6 months of the FITT-C intervention or non-directive telephone support. The FITT-C intervention was designed to reduce distress in caregivers and is based on the McMaster Model of Family Functioning, transition theory, and Lazarus and Folkman's Stress and Coping Models. The primary dependent variables were depressive symptoms (Centers for Epidemiological Studies - Depression) and burden (Zarit Burden Interview, Revised Memory and Behavior Problems Checklist - Reaction). Secondary outcome measures included family functioning, self-efficacy, and health-related quality of life. Results of the study will provide important data about the efficacy of a telephone-based approach to reduce distress in dementia caregivers.

    Instrumental activities scales allow the assessment of the functional status of the elderly; however, those currently used have gender bias and insufficient cross-cultural validation. The main objectives of this study were to perform the cross-cultural validation of the modified "VIDA: Daily living of the elderly questionnaire", created in Spain, into the Spanish spoken language in the City of Buenos Aires, and to evaluate its telephonic reliability. The secondary objective was to assess the concurrent validity of the modified VIDA questionnaire with the Lawton and Brody scale. The experts discussion group assessed the questionnaire vocabulary and proposed modifications according to the local language. We performed a pilot study to evaluate its comprehension, vocabulary and length. Afterwards we interviewed patients in person and after 14 days by telephone. We analyzed the global, inter and intra-observer reliability in both, the in person and the telephonic questionnaire, obtaining intra-class correlation coefficients of 0.95 (CI 95% 0.91-0.99), 0.99 (CI 95% 0.97-1.00) and 0.94 (IC 95% 0.87-1.00) respectively. Additionally, we obtained a very good correlation in both modalities between the modified VIDA questionnaire and the Lawton and Brody scale, with no differences regarding the patient's gender. In conclusion, the modified VIDA questionnaire was cross-culturally adapted in Buenos Aires City. Its implementation is reliable and valid both in person and by telephone.

    We examined measurement invariance and age-related robustness of a short 15-item Big Five Inventory (BFI-S) of personality dimensions, which is well suited for applications in large-scale multidisciplinary surveys. The BFI-S was assessed in three different interviewing conditions: computer-assisted or paper-assisted face-to-face interviewing, computer-assisted telephone interviewing, and a self-administered questionnaire. Randomized probability samples from a large-scale German panel survey and a related probability telephone study were used in order to test method effects on self-report measures of personality characteristics across early, middle, and late adulthood. Exploratory structural equation modeling was used in order to test for measurement invariance of the five-factor model of personality trait domains across different assessment methods. For the short inventory, findings suggest strong robustness of self-report measures of personality dimensions among young and middle-aged adults. In old age, telephone interviewing was associated with greater distortions in reliable personality assessment. It is concluded that the greater mental workload of telephone interviewing limits the reliability of self-report personality assessment. Face-to-face surveys and self-administrated questionnaire completion are clearly better suited than phone surveys when personality traits in age-heterogeneous samples are assessed.

    2012-01-01

    Full Text Available Telephone conference presentation delivery was compared to face-to-face classroom delivery in an undergraduate business course setting to assess whether concern over presenting in front of the class and/or gender impacted presentation mode preference. After completing a classroom exercise, students (n=102 were surveyed and asked to compare delivery methods from two courses, one requiring a telephone conference and the other requiring a face-to-face classroom presentation, in terms of perceived effectiveness, feedback, teamwork, instructor cues, preparation time, and overall comfort. Independent sample t-test results indicated respondents who worried about presenting in front of the class believed the telephone conference format required more attention to verbal presentation quality, and they also worried more about presenting in the telephone conference format than respondents who did not worry about presenting in front of the class. In terms of gender, female respondents indicated more attention to visual aid was required during the teleconference format, believed the teleconference presentation format allowed for the same opportunity for feedback from the instructor as the formal presentation, were more likely to indicate they were concerned about speaking in front of the classroom during formal presentations, and were also more concerned about speaking during the teleconference than male respondents. Overall, results indicated the teleconference activity was perceived to be a practical alternative to the traditional face-to-face delivery method; however, females’ perceptions of discomfort across both delivery formats warrant further study.

    2005-01-01

    A small number of signaling pathways, no more than a dozen or so, form a control layer that is responsible for all signaling in and between cells of the human body. The signaling proteins belonging to the control layer determine what kinds of cells are made during development and how they function during adult life. Malfunctions in the proteins belonging to the control layer are responsible for a host of human diseases ranging from neurological disorders to cancers. Most drugs target components in the control layer, and difficulties in drug design are intimately related to the architecture of the control layer. Molecular and Cellular Signaling provides an introduction to molecular and cellular signaling in biological systems with an emphasis on the underlying physical principles. The text is aimed at upper-level undergraduates, graduate students and individuals in medicine and pharmacology interested in broadening their understanding of how cells regulate and coordinate their core activities and how diseases ...

    Louise Farrer

    Full Text Available BACKGROUND: Telephone helplines are frequently and repeatedly used by individuals with chronic mental health problems and web interventions may be an effective tool for reducing depression in this population. AIM: To evaluate the effectiveness of a 6 week, web-based cognitive behaviour therapy (CBT intervention with and without proactive weekly telephone tracking in the reduction of depression in callers to a helpline service. METHOD: 155 callers to a national helpline service with moderate to high psychological distress were recruited and randomised to receive either Internet CBT plus weekly telephone follow-up; Internet CBT only; weekly telephone follow-up only; or treatment as usual. RESULTS: Depression was lower in participants in the web intervention conditions both with and without telephone tracking compared to the treatment as usual condition both at post intervention and at 6 month follow-up. Telephone tracking provided by a lay telephone counsellor did not confer any additional advantage in terms of symptom reduction or adherence. CONCLUSIONS: A web-based CBT program is effective both with and without telephone tracking for reducing depression in callers to a national helpline.

    2015-04-01

    Full Text Available Background: Teaching interns patient-centered communication skills, including making structured telephone calls to patients following discharge, may improve transitions of care. Objective: To explore associations between a patient-centered care (PCC curriculum and patients’ perspectives of the quality of transitional care. Methods: We implemented a novel PCC curriculum on one of four inpatient general medicine resident teaching teams in which interns make post-discharge telephone calls to patients, contact outpatient providers, perform medication adherence reviews, and engage in patient-centered discharge planning. Between July and November of 2011, we conducted telephone surveys of patients from all four teaching teams within 30 days of discharge. In addition to asking if patients received a call from their hospital physician (intern, we administered the 3-Item Care Transitions Measure (CTM-3, which assesses patients’ perceptions of preparedness for the transition from hospital to home (possible score range 0–100. Results: The CTM-3 scores (mean±SD of PCC team patients and standard team patients were not significantly different (82.4±17.3 vs. 79.6±17.6, p=0.53. However, regardless of team assignment, patients who reported receiving a post-discharge telephone call had significantly higher CTM-3 scores than those who did not (84.7±16.0 vs. 78.2±17.4, p=0.03. Interns exposed to the PCC curriculum called their patients after discharge more often than interns never exposed (OR=2.78, 95% CI [1.25, 6.18], p=0.013. Conclusions: The post-discharge telephone call, one element of PCC, was associated with higher CTM-3 scores – which, in turn, have been shown to lessen patients’ risk of emergency department visits within 30 days of discharge.

    2010-01-01

    We studied the patient experience of a telephone booster intervention, i.e. weekly reinforcement of the clinic advice regarding lifestyle modification advice to support weight loss. Forty six adults with Type 2 diabetes and a body mass index >28 kg/m(2) were randomised into either intervention (n = 25) or control (n = 21) groups. Semi-structured interviews were conducted with the intervention group participants to explore their views and experiences. The patients were satisfied or very satisfied with the telephone calls and most would recommend the intervention to others in a similar situation. The content of the telephone follow-up met their need for on-going support. The benefits arising from the telephone calls included: being reminded to comply with their regimen; prompting and motivating adherence to diabetes self-care behaviours; improved self-esteem; and feeling 'worthy of interest'. The convenience and low cost of telephone support has much potential in chronic disease management.

  16. Environment Aware Cellular Networks

    KAUST Repository

    Ghazzai, Hakim

    2015-02-01

    The unprecedented rise of mobile user demand over the years have led to an enormous growth of the energy consumption of wireless networks as well as the greenhouse gas emissions which are estimated currently to be around 70 million tons per year. This significant growth of energy consumption impels network companies to pay huge bills which represent around half of their operating expenditures. Therefore, many service providers, including mobile operators, are looking for new and modern green solutions to help reduce their expenses as well as the level of their CO2 emissions. Base stations are the most power greedy element in cellular networks: they drain around 80% of the total network energy consumption even during low traffic periods. Thus, there is a growing need to develop more energy-efficient techniques to enhance the green performance of future 4G/5G cellular networks. Due to the problem of traffic load fluctuations in cellular networks during different periods of the day and between different areas (shopping or business districts and residential areas), the base station sleeping strategy has been one of the main popular research topics in green communications. In this presentation, we present several practical green techniques that provide significant gains for mobile operators. Indeed, combined with the base station sleeping strategy, these techniques achieve not only a minimization of the fossil fuel consumption but also an enhancement of mobile operator profits. We start with an optimized cell planning method that considers varying spatial and temporal user densities. We then use the optimal transport theory in order to define the cell boundaries such that the network total transmit power is reduced. Afterwards, we exploit the features of the modern electrical grid, the smart grid, as a new tool of power management for cellular networks and we optimize the energy procurement from multiple energy retailers characterized by different prices and pollutant

    2010-10-01

    Full Text Available Abstract Background An estimated 285 million people worldwide have diabetes and its prevalence is predicted to increase to 439 million by 2030. For the year 2010, it is estimated that 3.96 million excess deaths in the age group 20-79 years are attributable to diabetes around the world. Self-management is recognised as an integral part of diabetes care. This paper describes the protocol of a randomised controlled trial of an automated interactive telephone system aiming to improve the uptake and maintenance of essential diabetes self-management behaviours. Methods/Design A total of 340 individuals with type 2 diabetes will be randomised, either to the routine care arm, or to the intervention arm in which participants receive the Telephone-Linked Care (TLC Diabetes program in addition to their routine care. The intervention requires the participants to telephone the TLC Diabetes phone system weekly for 6 months. They receive the study handbook and a glucose meter linked to a data uploading device. The TLC system consists of a computer with software designed to provide monitoring, tailored feedback and education on key aspects of diabetes self-management, based on answers voiced or entered during the current or previous conversations. Data collection is conducted at baseline (Time 1, 6-month follow-up (Time 2, and 12-month follow-up (Time 3. The primary outcomes are glycaemic control (HbA1c and quality of life (Short Form-36 Health Survey version 2. Secondary outcomes include anthropometric measures, blood pressure, blood lipid profile, psychosocial measures as well as measures of diet, physical activity, blood glucose monitoring, foot care and medication taking. Information on utilisation of healthcare services including hospital admissions, medication use and costs is collected. An economic evaluation is also planned. Discussion Outcomes will provide evidence concerning the efficacy of a telephone-linked care intervention for self-management of

  18. Cellular communication through light.

    Directory of Open Access Journals (Sweden)

    Daniel Fels

    Full Text Available Information transfer is a fundamental of life. A few studies have reported that cells use photons (from an endogenous source as information carriers. This study finds that cells can have an influence on other cells even when separated with a glass barrier, thereby disabling molecule diffusion through the cell-containing medium. As there is still very little known about the potential of photons for intercellular communication this study is designed to test for non-molecule-based triggering of two fundamental properties of life: cell division and energy uptake. The study was performed with a cellular organism, the ciliate Paramecium caudatum. Mutual exposure of cell populations occurred under conditions of darkness and separation with cuvettes (vials allowing photon but not molecule transfer. The cell populations were separated either with glass allowing photon transmission from 340 nm to longer waves, or quartz being transmittable from 150 nm, i.e. from UV-light to longer waves. Even through glass, the cells affected cell division and energy uptake in neighboring cell populations. Depending on the cuvette material and the number of cells involved, these effects were positive or negative. Also, while paired populations with lower growth rates grew uncorrelated, growth of the better growing populations was correlated. As there were significant differences when separating the populations with glass or quartz, it is suggested that the cell populations use two (or more frequencies for cellular information transfer, which influences at least energy uptake, cell division rate and growth correlation. Altogether the study strongly supports a cellular communication system, which is different from a molecule-receptor-based system and hints that photon-triggering is a fine tuning principle in cell chemistry.

    2009-04-01

    Full Text Available Abstract Background Whether low-intensity radiofrequency radiation damages the blood-brain barrier has long been debated, but little or no consideration has been given to the blood-cerebrospinal fluid barrier. In this cross-sectional study we tested whether long-term and/or short-term use of wireless telephones was associated with changes in the serum transthyretin level, indicating altered transthyretin concentration in the cerebrospinal fluid, possibly reflecting an effect of radiation. Methods One thousand subjects, 500 of each sex aged 18–65 years, were randomly recruited using the population registry. Data on wireless telephone use were assessed by a postal questionnaire and blood samples were analyzed for serum transthyretin concentrations determined by standard immunonephelometric techniques on a BN Prospec® instrument. Results The response rate was 31.4%. Logistic regression of dichotomized TTR serum levels with a cut-point of 0.31 g/l on wireless telephone use yielded increased odds ratios that were statistically not significant. Linear regression of time since first use overall and on the day that blood was withdrawn gave different results for males and females: for men significantly higher serum concentrations of TTR were seen the longer an analogue telephone or a mobile and cordless desktop telephone combined had been used, and in contrast, significantly lower serum levels were seen the longer an UMTS telephone had been used. Adjustment for fractions of use of the different telephone types did not modify the effect for cumulative use or years since first use for mobile telephone and DECT, combined. For women, linear regression gave a significant association for short-term use of mobile and cordless telephones combined, indicating that the sooner blood was withdrawn after the most recent telephone call, the higher the expected transthyretin concentration. Conclusion In this hypothesis-generating descriptive study time since first

The blinker is represented as the basic computational unit, and it is shown how it can be recreated in case of a failure. Stateless failover using primary-backup mechanism is demonstrated. The details of the CA components used in the configuration and its working are described, and a simulation of the complete configuration is also presented.

  3. A Simple Scheme for Improved Performance of Fixed Outage Rate Cellular System

    Directory of Open Access Journals (Sweden)

    Hussein M.A. Basi

    2004-01-01

    Full Text Available The traffic characteristic of mobile cellular systems is rather distinct from that of a fixed telephone network. However the system planning and design are still carried out with the tools of conventional traffic theory. In the recent days much work is being done in the performance evaluation of mobile or cellular communication systems in order to develop a system with greater efficiency. The useful parameters to estimate the performance of the system are voice quality, frequency spectrum efficiency and Grade of Service (GOS. The grade of service will be affected due to outage of channels. In this study, a new scheme is proposed to reduce lost calls due to channel outage in the fixed rate outage cellular system. In this proposed scheme the call will never dropped but may be delayed. The system performance is evaluated for different conditions and the results are discussed.

    The Telephone Lifestyle Coaching (TLC) program provided telephone-based coaching for six lifestyle behaviors to 5321 Veterans at 24 Veterans Health Administration (VHA) medical facilities. The purpose of the study was to conduct an evaluation of the TLC program to identify factors associated with successful implementation. A mixed-methods study design was used. Quantitative measures of organizational readiness for implementation and facility complexity were used to purposively select a subset of facilities for in-depth evaluation. Context assessments were conducted using interview transcripts. The Consolidated Framework for Implementation Research (CFIR) was used to guide qualitative data collection and analysis. Factors most strongly correlated with referral rates included having a skilled implementation leader who used effective multi-component strategies to engage primary care clinicians as well as general clinic structures that supported implementation. Evaluation findings pointed to recommendations for local and national leaders to help anticipate and mitigate potential barriers to successful implementation.

    The annoyance of noise in hearing instruments caused by electromagnetic interference from Global systems for Mobile Communication (GSM) and Digital European Cordless Telecommunication (DECT) mobile telephones has been subjectively evaluated by test subjects. The influence on speech recognition from...... the GSM and the DECT noises was also determined. The measurements involved seventeen hearing-imparied subjects. The annoyance was tested with GSM and DECT noise, each one mixed with continuous speech, a mall environment noise, or an office environment noise. Speech recognition was tested with the DANTALE...... word material mixed with GSM and DECT noise. The listening tests showed that if the noise level is acceptable so also is speech recognition. The results agree well with an investigation carried out on normal-hearing subjects. If a hearing instrument user is able to use a telephone without annoyance...

    Full Text Available Customer complaint has been the important feedback for modern enterprises to improve their product and service quality as well as the customer’s loyalty. As one of the commonly used manners in customer complaint, telephone communication carries rich emotional information of speeches, which provides valuable resources for perceiving the customer’s satisfaction and studying the complaint handling skills. This paper studies the characteristics of telephone complaint speeches and proposes an analysis method based on affective computing technology, which can recognize the dynamic changes of customer emotions from the conversations between the service staff and the customer. The recognition process includes speaker recognition, emotional feature parameter extraction, and dynamic emotion recognition. Experimental results show that this method is effective and can reach high recognition rates of happy and angry states. It has been successfully applied to the operation quality and service administration in telecom and Internet service company.

    Full Text Available Descriptive epidemiology research involves collecting data from large numbers of subjects. Obtaining these data requires approaches designed to achieve maximum participation or response rates among respondents possessing the desired information. We analyze participation and response rates in a population-based epidemiological study though a telephone survey and identify factors implicated in consenting to participate. Rates found exceeded those reported in the literature and they were higher for afternoon calls than for morning calls. Women and subjects older than 40 years were the most likely to answer the telephone. The study identified geographical differences, with higher RRs in districts in southern Spain that are not considered urbanized. This information may be helpful for designing more efficient community epidemiology projects.

    Big Data on electronic records of social interactions allow approaching human behaviour and sociality from a quantitative point of view with unforeseen statistical power. Mobile telephone Call Detail Records (CDRs), automatically collected by telecom operators for billing purposes, have proven especially fruitful for understanding one-to-one communication patterns as well as the dynamics of social networks that are reflected in such patterns. We present an overview of empirical results on the multi-scale dynamics of social dynamics and networks inferred from mobile telephone calls. We begin with the shortest timescales and fastest dynamics, such as burstiness of call sequences between individuals, and "zoom out" towards longer temporal and larger structural scales, from temporal motifs formed by correlated calls between multiple individuals to long-term dynamics of social groups. We conclude this overview with a future outlook.

  11. Countrywide rainfall maps from a commercial cellular telecommunication network

    Accurate rainfall observations with high spatial and temporal resolutions are needed for hydrological applications, agriculture, meteorology, and climate monitoring. However, the majority of the land surface of the earth lacks accurate rainfall information. Many countries do not have continuously operating weather radars, and have no or few rain gauges. A new development is rainfall estimation from microwave links of commercial cellular telecommunication networks. Such networks cover large parts of the land surface of the earth and have a high density, especially in urban areas. The estimation of rainfall using commercial microwave links could therefore become a valuable source of information. The data produced by microwave links is essentially a by-product of the communication between mobile telephones. Rainfall attenuates the electromagnetic signals transmitted from one telephone tower to another. By measuring the received power at one end of a microwave link as a function of time, the path-integrated attenuation due to rainfall can be calculated. Previous studies have shown that average rainfall intensities over the length of a link can be derived from the path-integrated attenuation. A dataset from a commercial microwave link network over the Netherlands is analyzed, containing data from an unprecedented number of links (1500) covering the land surface of the Netherlands (35500 km2). This dataset consists of 24 days with substantial rainfall in June - September 2011. A rainfall retrieval algorithm is presented to derive rainfall intensities from the microwave link data, which have a temporal resolution of 15 min. Rainfall maps (1 km spatial resolution) are generated from these rainfall intensities using Kriging. This algorithm is suited for real-time application, and is calibrated on a subset (12 days) of the dataset. The other 12 days in the dataset are used to validate the algorithm. Both calibration and validation are done using gauge-adjusted radar data

    Full Text Available "Telestroke" is emerging as a potential timesaving, efficient means for evaluating patients experiencing acute ischemic stroke. It provides an opportunity for administration of thrombolytic drugs within the short therapeutic time window associated with AIS. We describe our experiences of the feasibility and safety of remote radiology interpretation with telephone consultation. Thammasat Stroke Center employs a computed tomography-digital imaging and communication in medicine (CT-DICOM image transfer by PACS (SYNAPSE-Fujifilm, providing a real-time CT image transferred directly to the stroke consultants. The patient data are communicated by traditional telephone conversation. Here, we assessed patients who received intravenous rt-PA treatment for ASI between October 2007 and January 2009. A total of 458 patients with AIS and transient ischemic attack (TIA were admitted to a stroke unit during the study period. One hundred patients received intravenous rt-PA (21%. Median NIHSS before thrombolysis was 15 (3-34. Mean door-to-needle time was 54 minutes (15-125. Mean onset-to-treatment time OTT was 160 minutes (60-270. There were 13 asymptomatic intracerebral hemorrhages and two (one fatal symptomatic intracerebral hemorrhages. At 3 months, 42 patients had achieved excellent recovery (mRS, 0-1 and 14 had died. Administration of rt-PA for AIS with remote radiology interpretation with telephone consultation was feasible and safe, and the system was well received. Further studies are needed to determine the benefit of this method as compared to the conventional telephone consultation alone.

    Abstract The traditional Random Digit Dialing method (list-assisted RDD using a frame of landline phone numbers) is clearly under threat. The difficulty and costs of completing telephone surveys have increased due to rising rates of refusal and non-contact. The completeness of coverage of list-assisted RDD samples has diminished due to the proliferation of cell-phone only households. The ability of list-assisted RDD to capture young, mobile, unmarried, and minority households is thus dimin...

    The continuing development and refinement of empirically supported interventions to increase participation in posttreatment care and promote sustained abstinence from illicit drug use is a priority for the addictions field. The purpose of this study was to assess the combined and relative effectiveness of four types of counseling styles, delivered by telephone, relative to a no call control condition. Stimulant users (N = 302) were randomized to one of four low-cost, telephone support protocols (unstructured/nondirective, unstructured/directive, structured/nondirective, structured/directive) or a standard referral to aftercare without telephone counseling (control). All of the study participants were nearing the completion of (or had completed) an intensive phase of structured, outpatient stimulant abuse treatment. Drug use and aftercare participation were assessed at 3 and 12 months following randomization. Intent-to-treat analyses showed no significant time-by-group interactions for these primary outcomes. Subsequent analyses, however, revealed a significant difference between the aggregated call groups and the control group at the time of the 3-month follow-up. The mean ASI drug use severity composite score for subjects in the call conditions declining from .058 at baseline to .048 at 3 months, whereas the no call/control group average score increased from .053 to .062 (χ (1) = 4.95, p = .026). A similar-and slightly stronger-effect was found when the study sample was restricted to those reporting any use during the month prior to the baseline interview (n = 152). This study provides modest support for the telephone-based counseling approaches strategies examined in this project. Subsequent research will assess interactions between patient characteristics and counseling styles, and improved identification of which treatment graduates might be more likely to benefit from this type of continuing support.

    Background Surveillance for influenza and influenza-like illness (ILI) is important for guiding public health prevention programs to mitigate the morbidity and mortality caused by influenza, including pandemic influenza. Nontraditional sources of data for influenza and ILI surveillance are of interest to public health authorities if their validity can be established. Methods/Principal Findings National telephone triage call data were collected through automated means for purposes of syndromic surveillance. For the 17 states with at least 500,000 inhabitants eligible to use the telephone triage services, call volume for respiratory syndrome was compared to CDC weekly number of influenza isolates and percentage of visits to sentinel providers for ILI. The degree to which the call data were correlated with either CDC viral isolates or sentinel provider percentage ILI data was highly variable among states. Conclusions Telephone triage data in the U.S. are patchy in coverage and therefore not a reliable source of ILI surveillance data on a national scale. However, in states displaying a higher correlation between the call data and the CDC data, call data may be useful as an adjunct to state-level surveillance data, for example at times when sentinel surveillance is not in operation or in areas where sentinel provider coverage is considered insufficient. Sufficient population coverage, a specific ILI syndrome definition, and the use of a threshold of percentage of calls that are for ILI would likely improve the utility of such data for ILI surveillance purposes.

    Full Text Available This study assessed the effects of a 6-week telephone based intervention on the pain intensity and physical function of patients with knee osteoarthritis (OA, and compared the results to physiotherapy conducted in the clinic. Fifty randomly selected patients with knee OA were assigned to one of two treatment groups: a clinic group (CG and a tele-physiotherapy group (TG. The CG received thrice-weekly physiotherapist administered osteoarthritis-specific exercises in the clinic for six weeks. The TG received structured telephone calls thrice-weekly at home, to monitor self-administered osteoarthritis-specific exercises. Participants’ pain intensity and physical function were assessed at baseline, two, four, and six weeks, in the clinic environment. Within group comparison showed significant improvements across baseline, and at weeks two, four, and six for both TG and CG’s pain intensity and physical function. Between-group comparison of CG and TG’s pain intensity and physical function at baseline and weeks two, four, and six showed no significant differences. This study demonstrated that a six-week course of structured telephone calls thrice-weekly to patients at their home, to monitor self-administered osteoarthritis-specific exercises for patients with knee OA (i.e., tele-physiotherapy achieved comparable results to physiotherapy conducted in the clinic.   12.00 Normal 0 false false false EN-US X-NONE X-NONE

    Full Text Available Incorrect beliefs about memory have wide-ranging implications. We recently reported the results of a survey showing that a substantial proportion of the United States public held beliefs about memory that conflicted with those of memory experts. For that survey, respondents answered recorded questions using their telephone keypad. Although such robotic polling produces reliable results that accurately predicts the results of elections, it suffers from four major drawbacks: (1 telephone polling is costly, (2 typically, less than 10 percent of calls result in a completed survey, (3 calls do not reach households without a landline, and (4 calls oversample the elderly and undersample the young. Here we replicated our telephone survey using Amazon Mechanical Turk (MTurk to explore the similarities and differences in the sampled demographics as well as the pattern of results. Overall, neither survey closely approximated the demographics of the United States population, but they differed in how they deviated from the 2010 census figures. After weighting the results of each survey to conform to census demographics, though, the two approaches produced remarkably similar results: In both surveys, people averaged over 50% agreement with statements that scientific consensus shows to be false. The results of this study replicate our finding of substantial discrepancies between popular beliefs and those of experts and shows that surveys conducted on MTurk can produce a representative sample of the United States population that generates results in line with more expensive survey techniques.

    Modern radio communication is faced with a problem about how to distribute restricted frequency to users in a certain space. Since our task is to minimize the number of repeaters, a natural idea is enlarging coverage area. However, coverage has restrictions. First, service area has to be divided economically as repeater's coverage is limited. In this paper, our fundamental method is to adopt seamless cellular network division. Second, underlying physics content in frequency distribution problem is interference between two close frequencies. Consequently, we choose a proper frequency width of 0.1MHz and a relevantly reliable setting to apply one frequency several times. We make a few general assumptions to simplify real situation. For instance, immobile users yield to homogenous distribution; repeaters can receive and transmit information in any given frequency in duplex operation; coverage is mainly decided by antenna height. Two models are built up to solve 1000 users and 10000 users situations respectively....

    Metabolic engineering is the science of rewiring the metabolism of cells to enhance production of native metabolites or to endow cells with the ability to produce new products. The potential applications of such efforts are wide ranging, including the generation of fuels, chemicals, foods, feeds, and pharmaceuticals. However, making cells into efficient factories is challenging because cells have evolved robust metabolic networks with hard-wired, tightly regulated lines of communication between molecular pathways that resist efforts to divert resources. Here, we will review the current status and challenges of metabolic engineering and will discuss how new technologies can enable metabolic engineering to be scaled up to the industrial level, either by cutting off the lines of control for endogenous metabolism or by infiltrating the system with disruptive, heterologous pathways that overcome cellular regulation.

    2014-06-01

    Full Text Available The great challenge of the remarkably growing demand for personal communication mobile service in Libya has actively motivated Al-Madar Telephone Telecommunication Company to adopt various techniques in order to substantially improve its network capacity. An efficient allocation strategy of communication channels that could ensure good performance of the cellular network is critically needed, given the limited spectrum currently available that uses the Fixed Channel Allocation (FCA strategy. In this study, experimental investigations were conducted to improve Al-Madar Company network by proposing the evaluation of the adoption of the Local Packing Distributed Dynamic Channel Allocation (LP-DDCA strategy. The main reasons for proposing the adoption of the LP-DDCA strategy are; to minimize the call blocking probability, enhancing the network performance and increasing the number of network subscribers. This work has been done by applying actual data from an existing cellular network of Al-Madar Company in to the experimental simulation program. The results demonstrated clearly the superiority of the proposed the LP-DDCA strategy in the investigated locations (cells compared with the currently used FCA strategy. Conclusion: Application of the LP-DDCA strategy could give rise to substantial improvement in Al-Madar telecommunication mobile network performance and it will considerably increase the number of network subscribers.

Patients then wait again for surgery, if required. Patients with higher need are rarely prioritized, and there is the potential for increased morbidity for those who wait. There is generally no option of alternative care whilst waiting. This paper compares historical orthopedic outpatient clinic data with the outcomes of a physiotherapy-led initiative in one large Australian tertiary hospital.Methods: Two physiotherapists working within-scope conducted a telephone triage (October to December 2010 using a standard instrument for all new patients on the orthopedic waiting list. They were offered primary treatment options of retaining their appointment, being discharged, referral to a new model of assessment (multidisciplinary specialist clinic, or referral to physiotherapy. The outcomes were costs of the service, waiting time, and percentage of patients taking up management options. This was compared with a historical sample of new patients on the orthopedic waiting list (January to March 2009, whose treatment consumption was tracked longitudinally.Results: The telephone triage resulted in 16.4% patients being discharged directly (compared with 0.1% comparison sample. For approximately AU$17.00 per patient, the telephone triage process released 21 booked appointments on the outpatient clinic waiting list. Moreover, approximately 26% patients were referred directly to physiotherapy, which was not a primary management

    Welsh, David K; Noguchi, Takako

    2012-08-01

    Bioluminescence imaging of live cells has recently been recognized as an important alternative to fluorescence imaging. Fluorescent probes are much brighter than bioluminescent probes (luciferase enzymes) and, therefore, provide much better spatial and temporal resolution and much better contrast for delineating cell structure. However, with bioluminescence imaging there is virtually no background or toxicity. As a result, bioluminescence can be superior to fluorescence for detecting and quantifying molecules and their interactions in living cells, particularly in long-term studies. Structurally diverse luciferases from beetle and marine species have been used for a wide variety of applications, including tracking cells in vivo, detecting protein-protein interactions, measuring levels of calcium and other signaling molecules, detecting protease activity, and reporting circadian clock gene expression. Such applications can be optimized by the use of brighter and variously colored luciferases, brighter microscope optics, and ultrasensitive, low-noise cameras. This article presents a review of how bioluminescence differs from fluorescence, its applications to cellular imaging, and available probes, optics, and detectors. It also gives practical suggestions for optimal bioluminescence imaging of single cells.

    Cellular neurothekeoma (CNT) is a benign dermal tumor mainly affecting the head and neck and the upper extremities. It is characterized histologically by interconnecting fascicles of plump spindle or epithelioid cells with ample cytoplasm infiltrating in the reticular dermis. The histogenesis of CNT has been controversial, although it is generally regarded as an immature counterpart of classic/myxoid neurothekeoma, a tumor with nerve sheath differentiation. Two rare cases of CNT containing melanin-laden cells were described. Immunohistochemical study with NKI/C3, vimentin, epithelial membrane antigen, smooth muscle antigen, CD34, factor XIIIa, collagen type IV, S100 protein and HMB-45 was performed. Both cases showed typical growth pattern of CNT with interconnecting fascicles of epithelioid cells infiltrating in collagenous stroma. One of the nodules contained areas exhibiting atypical cytological features. Melanin-laden epithelioid or dendritic cells were diffusely scattered throughout one nodule, and focally present in the peripheral portion of the other nodule. Both nodules were strongly immunoreactive to NKI/C3 and vimentin, but negative to all the other markers employed. CNT harboring melanin-laden cells may pose diagnostic problems because of their close resemblance to nevomelanocytic lesions and other dermal mesenchymal tumors. These peculiar cases may also provide further clues to the histogenesis of CNT.

    Full Text Available Background: A large number of persons with psychiatric disorders are not seeking treatment due to various reasons, thus contributing to the huge treatment gap. One of the ways to bring these people into treatment is through telephonic helplines. Materials and Methods: Following a large number of suicides in the city of Chandigarh in 2003, The department of Psychiatry, GMCH, Chandigarh was designated as nodal center for the prevention of suicide. A 24-hour suicide prevention helpline was set up as an immediate measure to help persons in crisis. Apart from providing telephonic counseling to persons in crisis, the helpline coordinated with police, media, schools, radio stations etc., to reduce the number of suicides in the city. Results: Majority of the callers were males (65.93%, between 20 to 39 years old (56.34%, married (79.50%, had less than 12 years of formal education (60.68%, and were earning less than Rs. 5000/month (56.80%. 72.96% callers had contacted the mental health services for the first time. A significant number of persons (434, 13.26% called the helpline for marital, academic, stress-related problems. Majority of the calls were received between 8 A.M. and 2 P.M. The number of suicides in the city of Chandigarh showed a decline in the following years since the helpline was set up. Conclusions: The telephonic helpline seems to be a very effective way of getting persons into contact with health services. They are cost-effective, the person can maintain his confidentiality and devoid of stigma.

    Full Text Available Abstract Background The science of syndromic surveillance is still very much in its infancy. While a number of syndromic surveillance systems are being evaluated in the US, very few have had success thus far in predicting an infectious disease event. Furthermore, to date, the majority of syndromic surveillance systems have been based primarily in emergency department settings, with varying levels of enhancement from other data sources. While research has been done on the value of telephone helplines on health care use and patient satisfaction, very few projects have looked at using a telephone helpline as a source of data for syndromic surveillance, and none have been attempted in Canada. The notable exception to this statement has been in the UK where research using the national NHS Direct system as a syndromic surveillance tool has been conducted. Methods/design The purpose of our proposed study is to evaluate the effectiveness of Ontario's telephone nursing helpline system as a real-time syndromic surveillance system, and how its implementation, if successful, would have an impact on outbreak event detection in Ontario. Using data collected retrospectively, all "reasons for call" and assigned algorithms will be linked to a syndrome category. Using different analytic methods, normal thresholds for the different syndromes will be ascertained. This will allow for the evaluation of the system's sensitivity, specificity and positive predictive value. The next step will include the prospective monitoring of syndromic activity, both temporally and spatially. Discussion As this is a study protocol, there are currently no results to report. However, this study has been granted ethical approval, and is now being implemented. It is our hope that this syndromic surveillance system will display high sensitivity and specificity in detecting true outbreaks within Ontario, before they are detected by conventional surveillance systems. Future results will be

    Full Text Available Abstract Background Older adults may find it problematic to attend hospital appointments due to the difficulty associated with travelling to, within and from a hospital facility for the purpose of a face-to-face assessment. This study aims to investigate equivalence between telephone and face-to-face administration for the Frenchay Activities Index (FAI and the Euroqol-5D (EQ-5D generic health-related quality of life instrument amongst an older adult population. Methods Patients aged >65 (n = 53 who had been discharged to the community following an acute hospital admission underwent telephone administration of the FAI and EQ-5D instruments seven days prior to attending a hospital outpatient appointment where they completed a face-to-face administration of these instruments. Results Overall, 40 subjects' datasets were complete for both assessments and included in analysis. The FAI items had high levels of agreement between the two modes of administration (item kappa's ranged 0.73 to 1.00 as did the EQ-5D (item kappa's ranged 0.67–0.83. For the FAI, EQ-5D VAS and EQ-5D utility score, intraclass correlation coefficients were 0.94, 0.58 and 0.82 respectively with paired t-tests indicating no significant systematic difference (p = 0.100, p = 0.690 and p = 0.290 respectively. Conclusion Telephone administration of the FAI and EQ-5D instruments provides comparable results to face-to-face administration amongst older adults deemed to have cognitive functioning intact at a basic level, indicating that this is a suitable alternate approach for collection of this information.

    Full Text Available Abstract Background Effective communication between clinicians is essential for safe, efficient healthcare. We undertook a study to determine the longer-term effectiveness of an education session employing a structured method to teach referral-making skills to medical students. Methods All final year medical students received a forty-five minute education intervention consisting: discussion of effective telephone referrals; video viewing and critique; explanation, demonstration and practice using ISBAR; provision of a memory aid for use in their clinical work. Audio recordings were taken during a subsequent standardised simulation scenario and blindly assessed using a validated scoring system. Recordings were taken immediately before (control, several hours after (intervention, and at approximately six months after the education. Retention of the acronym and self-reports of transfer to the clinical environment were measured with a questionnaire at eight months. Results Referral clarity at six months was significantly improved from pre-intervention, and referral content showed a trend towards improvement. Both measures were lower than the immediate post-education test. The ISBAR acronym was remembered by 59.4% (n = 95/160 and used by the vast majority of the respondents who had made a clinical telephone referral (n = 135/143; 94.4%. Conclusions A brief education session improved telephone communication in a simulated environment above baseline for over six months, achieved functional retention of the acronym over a seven to eight month period and resulted in self reports of transfer of the learning into practice.

The participants were randomized into two groups: the intervention group that received structured telephone follow-up after discharge and the control group that received routine health care. Pain, functional ability, quality of life, and depression survey scores were measured before and after TKA. The intergroup and intragroup differences were analyzed during the 12 months following discharge.Results: There were no significant differences in the sociodemographic characteristics of both groups. The mean home-exercise time and total days in the intervention group were significantly higher than those in the control group. Variable scores differed significantly between groups. Pain, functional ability, quality of life, and depression improved significantly after TKA in both groups, and the intervention group had greater improvement in mental health and active range of motion.Conclusion: Undergoing a TKA can significantly reduce the patient’s pain from osteoarthritis while improving the overall physical function and quality of life. Furthermore, a structured telephone follow-up can improve patient adherence to home exercise after TKA. Keywords: quality of life, pain, home exercises, patient-reported outcomes

    The current reimbursement structure of health care in the United States motivates the providers of health care services to deliver these services with a cost-conscious mentality without compromising quality. This has led to the development of alternative methods of delivering health care services, one of which is computerized telephone nurse triage. This study investigates service quality from the perception of callers who used this system on behalf of a pediatric client. Cost was evaluated by comparing what the caller would have done if they did not speak with nurse triage with what they actually did after their interaction. A modified version of the SERVQUAL tool was administered via telephone survey to members of a managed health care plan who recently used nurse triage services for a pediatric patient. Findings were that the majority of callers--employed female parents--rated the level of service quality very highly. Education, employment status, age of the caller, child gender, birth order among siblings, and age of child did not affect the rating of service quality. Relationship to the child had an effect on the rating of service quality as men/fathers rated the level of service quality slightly lower than their female/mother counterparts. The evaluation of cost revealed that the action taken by the caller after they spoke with the nurse resulted in significant cost savings. Computerized telephone nurse triage is a well-accepted cost-saving alternative method of health care delivery that can effectively serve a variety of callers and pediatric patients.

    Following the introduction of a new nurse-led telephone referral service to a dedicated paediatric emergency assessment unit (PEAU), a study was conducted to determine the views of general practitioners (GPs) who use the service. The PEAU operates between 10 am and 10 pm on weekdays and between 10 am and 6 pm at weekends. The unit has four beds and treatment and stabilization areas, plus associated services in a dedicated area of a regional child health unit. The design utilized a faxed questionnaire over a 1-month period to all consenting GPs using the PEAU with a postal questionnaire follow-up. Non-parametric Likert scores and qualitative data were used to determine levels of satisfaction with the service and the subsequent management of the referred children. Sixty-nine GPs referred 80 children to the PEAU via the service over a period of 1 month. All consented to participate and were sent a faxed questionnaire, which generated 39 (57%) responses. A follow-up questionnaire sent to the 39 respondents achieved a return of 25 (64%) responses. Thirty-four GPs agreed that referral via the dedicated nurse service was easier than the previous senior house officer referral system. Of the 25 GP respondents to the follow-up postal survey, the majority (17) agreed that the follow-up morning after discharge telephone call to parents by the PEAU nurses was helpful. Four GPs indicated that the 24-hour open access system, offered by the nursing staff, in which a parent may attend PEAU with a discharged child causing concern without a previous appointment, does not always work. This study has shown that a nurse-led telephone referral system to a PEAU for GPs and the subsequent management of the children has been favourably received.

    Using archival data, this case study systematically examines telephone calls received by a regional sexual assault hotline in the Southeastern United States over a 5-year period. A stratified random sample (n = 383) reveals that hotline staff require diversity and depth in knowledge and skills, demonstrated by the hotline's primary use as a crisis service, combined with notable use by long-term survivors. Findings include the utility of the hotline by survivors and community stakeholders, categories of assault, the time gap between incidents occurring and contacting the hotline, call severity and urgency, and services and referrals provided. Implications for training, practice, and future research are discussed.

    We conducted a randomized-controlled trial of telephone support services (TSS) versus enhanced usual care (EUC) for women who had reported intimate partner violence (IPV) within the past year during a visit to a pediatric emergency department. TSS nurse interventionists identified appropriate referrals to community programs, helped participants by problem-solving barriers to obtaining these local services, and provided social support. Three hundred women, ages 18 years and above were recruited. The TSS and EUC groups did not differ on any outcome variable, including IPV victimization, feelings of chronic vulnerability to a perpetrator, depressive symptoms, and posttraumatic stress disorder symptoms.

    As the theoretical foundations of multiple-antenna techniques evolve and as these multiple-input multiple-output (MIMO) techniques become essential for providing high data rates in wireless systems, there is a growing need to understand the performance limits of MIMO in practical networks. To address this need, MIMO Communication for Cellular Networks presents a systematic description of MIMO technology classes and a framework for MIMO system design that takes into account the essential physical-layer features of practical cellular networks. In contrast to works that focus on the theoretical performance of abstract MIMO channels, MIMO Communication for Cellular Networks emphasizes the practical performance of realistic MIMO systems. A unified set of system simulation results highlights relative performance gains of different MIMO techniques and provides insights into how best to use multiple antennas in cellular networks under various conditions. MIMO Communication for Cellular Networks describes single-user,...

    2016-06-01

    The impact of a payer-provided telephone-based chronic disease management program on medical expenditures was evaluated using claims data from 126,245 members in employer self-ensured health plans (16,224 with a chronic disease in a group enrolled in the self-management program, 13,509 with a chronic disease in a group not participating in the program). A random effects regression model controlling for retrospective risk, age, sex, and diagnosis with a chronic disease was used to determine the impact of program participation on market-adjusted health care expenditures. Further confirmation of results was obtained by an ordinary least squares model comparing market- and risk-adjusted costs to the length of participation in the program. Participation in the program is associated with an average annual savings of $1157.91 per enrolled member in health care expenditures. Savings increase with the length of participation in the program. The results support the use of telephone-based patient self-management of chronic disease as a cost-effective means to reduce health care expenditures in the working-age population.

    In 2003, the Indiana Office of Medicaid Policy and Planning launched the Indiana Chronic Disease Management Program (ICDMP), a programme intended to improve the health and healthcare utilization of 15,000 Aged, Blind and Disabled Medicaid members living with diabetes and/or congestive heart failure in Indiana. Within ICDMP, programme components derived from the Chronic Care Model and education based on an integrated theoretical framework were utilized to create a telephonic care management intervention that was delivered by trained, non-clinical Care Managers (CMs) working under the supervision of a Registered Nurse. CMs utilized computer-assisted health education scripts to address clinically important topics, including medication adherence, diet, exercise and prevention of disease-specific complications. Employing reflective listening techniques, barriers to optimal self-management were assessed and members were encouraged to engage in health-improving actions. ICDMP evaluation results suggest that this low-intensity telephonic intervention shifted utilization and lowered costs. We discuss this patient-centred method for motivating behaviour change, the theoretical constructs underlying the scripts and the branched-logic format that makes them suitable to use as a computer-based application. Our aim is to share these public-domain materials with other programmes.

    Full Text Available This study aims to analyze the global mobile phones by examining the instruments stimulating the diffusion pattern. A rigorous demand model is estimated using global mobile telecommu-nications panel dataset comprised with 51 countries classified in order to World Bank income categories from 1990-2007. In particular, the paper examines what factors contribute the most to the deployment of global mobile telephones. To construct an econometric model, the number of subscribers to mobile phone per 100 inhabitants is taken as dependent variable, while the following groups of variables (1 GDP per capita income and charges, (2 competition policies (3 telecom infrastructure (4 technological innovations (5 others are selected as independent variables. Estimation results report the presence of substantial disparity among groups. Additionally GDP per capita income and own-price elasticity comprised with call rate, subscription charges, are reported. The analysis of impulse responses for price, competition policies, and technological innovations such as digitalization of mobile network, mobile network coverage indicates that substantial mobile telephone growth is yet to be realized especially in developing countries. A new and important empirical finding is that there are still many opportunities available for mobile phone development in the world pro-poor nations by providing better telecom infrastructure.

    Full Text Available Abstract Background Teamwork is important for patient care and outcome in emergencies. In rural areas, efficient communication between rural hospitals and regional trauma centers optimise decisions and treatment of trauma patients. Little is known on potentials and effects of virtual team to team cooperation between rural and regional trauma teams. Methods We adapted a video conferencing (VC system to the work process between multidisciplinary teams responsible for trauma as well as medical emergencies between one rural and one regional (university hospital. We studied how the teams cooperated during simulated critical scenarios, and compared VC with standard telephone communication. We used qualitative observations and interviews to evaluate results. Results The team members found VC to be a useful tool during emergencies and for building "virtual emergency teams" across distant hospitals. Visual communication combined with visual patient information is superior to information gained during ordinary telephone calls, but VC may also cause interruptions in the local teamwork. Conclusion VC can improve clinical cooperation and decision processes in virtual teams during critical patient care. Such team interaction requires thoughtful organisation, training, and new rules for communication.

    Job burnout is a major concern within the service industry. However, there is a lack of research exploring positive resources for combating burnout among telephone operators. The purpose of this study was to examine the associations between resilience, psychological empowerment, and job burnout, and the mediating role of psychological empowerment. A cross-sectional survey of 575 telephone operators was conducted in 2 call centers in Shandong Province, China. Self-report questionnaires were used to assess job burnout symptoms, resilience, and psychological empowerment. Hierarchical linear regression was performed to analyze the degree to which resilience and psychological empowerment are associated with job burnout, and the mediating role of psychological empowerment. The results showed that resilience and psychological empowerment had significant "net effects" on job burnout, which may represent positive resources for combating job burnout. Psychological empowerment may partially mediate the relationship between resilience and job burnout. Thus, interventions focused on resilience and psychological empowerment may be useful options for managers concerned about burnout.

    Spouses of returning Iraq (Operation Iraqi Freedom, OIF) and Afghanistan (Operation Enduring Freedom, OEF) military service members report increased depression and anxiety post deployment as they work to reintegrate the family and service member. Reconnecting the family, renegotiating roles that have shifted, reestablishing communication patterns, and dealing with mental health concerns are all tasks that spouses must undertake as part of reintegration. We tested telephone support groups focusing on helping spouses with these basic reintegration tasks. Year-long telephone support groups focused on education, skills building (communication skills, problem solving training, cognitive behavioral techniques, stress management), and support. Spouse depression and anxiety were decreased and perceived social support was increased during the course of the study. In subgroup analyses, spouses with husbands whose injuries caused care difficulties had a positive response to the intervention. However, they were more likely to be depressed, be anxious, and have less social support compared to participants who had husbands who had no injury or whose injury did not cause care difficulty. Study findings suggest that this well-established, high-access intervention can help improve quality of life for military spouses who are struggling with reintegration of the service member and family.

    This study is an evaluation of a unique "surveillance nurse" telephone support intervention for community-dwelling elderly individuals in a home care program. A combined propensity-based covariate-matching procedure was used to pair each individual who received the intervention ("treatment" condition, nT = 930) to a similar individual who did not receive the intervention ("control" condition, nC1 = 930) from among a large pool of potential control individuals (nC0 = 4656). The intervention consisted of regularly scheduled telephone calls from a surveillance nurse to proactively assess the individual's well-being, care plan status, use of and need for services (home support, adult day program, physiotherapy, etc.) and home environment (e.g., informal caregiver support). Treatment and control conditions were compared with respect to four service utilization outcomes: (1) rate of survival in the community before institutionalization in an assisted living or nursing home facility or death, (2) rate of emergency room registrations, (3) rate of acute care hospitalizations, and (4) rate of days in hospital, during home care enrollment. Results indicated a beneficial effect of the surveillance nurse intervention on reducing rate of service utilization by increasing the duration of the home care episode.

    Electromagnetic interference (EMI) with electronic medical equipment by the handsets of mobile telephones is a well documented problem in hospitals. To gain information about how to build an EMI-free hospital and how to make rooms safe for mobile telephone handset use in the hospital building the authors measured the shielding capacities of a concrete wall, concrete blocks, a steel door, and steel-surfaced partition panels. The shielding capacities of these materials were 2-7 dB for the concrete wall, 6-8 dB for the concrete blocks, 19-27 dB for the steel door, and 20-37 dB for the steel-surfaced partition panels. These results indicate that care should be taken to shield electronic equipment from signals coming from neighboring rooms and from those under and above any patient room in which such equipment is in use. Electricity-conductive paint, electricity-conductive wallpaper, and electricity-conductive cloth are examples of inexpensive materials that can increase shielding capacity.

    Objective Nurse telephone counseling can improve the management of chronic conditions, but the effectiveness of this approach in underserved populations is unclear. This study evaluated the use of bilingual nurse-delivered telephone counseling in Korean Americans (KAs) participating in a community-based intervention trial to improve management of hypertension. Methods KAs were randomized to receive 12 months of hypertension-related telephone counseling that was more intensive (bi-weekly) or less intensive (monthly). Counseling logs were kept for 360 KAs who completed the pre- and post-intervention evaluations. Results The overall success rate for the intervention was 80.3%. The level of success was significantly influenced by the dose of counseling, employment status, and years of US residence. Over the 12-month counseling period, both groups showed improvement with regard to medication-taking, alcohol consumption, and exercise but not smoking, with no significant group differences. Conclusion Bilingual telephone counseling could reach monolingual KAs and improve their hypertension management behavior. Practice implications Bilingual nurse telephone counseling may have wide applicability, serving as an effective means of disseminating evidence-based chronic disease management guidelines to a linguistically isolated community with limited health resources and information.

    This study compared interview and telephone surveys to select the better method for regularly estimating nationwide vaccination coverage rates in Korea. Interview surveys using multi-stage cluster sampling and telephone surveys using stratified random sampling were conducted. Nationwide coverage rates were estimated in subjects with vaccination cards in the interview survey. The interview survey relative to the telephone survey showed a higher response rate, lower missing rate, higher validity and a less difference in vaccination coverage rates between card owners and non-owners. Primary vaccination coverage rate was greater than 90% except for the fourth dose of DTaP (diphtheria/tetanus/pertussis), the third dose of polio, and the third dose of Japanese B encephalitis (JBE). The DTaP4: Polio3: MMR1 fully vaccination rate was 62.0% and BCG1:HepB3:DTaP4:Polio3:MMR1 was 59.5%. For age-appropriate vaccination, the coverage rate was 50%-80%. We concluded that the interview survey was better than the telephone survey. These results can be applied to countries with incomplete registry and decreasing rates of landline telephone coverage due to increased cell phone usage and countries. Among mandatory vaccines, efforts to increase vaccination rate for the fourth dose of DTaP, the third dose of polio, JBE and regular vaccinations at recommended periods should be conducted in Korea.

    Nurses are mandated reporters of actual or suspected child maltreatment or the threat thereof. The purpose of this quality improvement project was to determine the knowledge and comfort of nurses in telephone triage in pediatric clinics when dealing with suspected or actual child abuse calls. Nurses (N = 17) from three pediatric primary care clinics and one specialty care orthopedic clinic were surveyed. Based on results of the survey showing a lack of knowledge and adequate referral resources perceived by the nursing staff, resources and staff education were developed, along with a script for guiding maltreatment calls toward standardization of care. Following the intervention, nurses reported an increased comfort level when doing telephone triage for child maltreatment calls, an increase in knowledge of risk factors for county resources. Further, they reported a substantial shift in opinion about the need for a standardized script when responding to child maltreatment telephone calls. Nurses undertaking telephone triage of high-risk child maltreatment calls can improve their comfort and knowledge through a survey of their needs and directed education and resource development for the management of child maltreatment telephone triage.

    Cellular Networks are in general quite robust and perform their biological functions against the environmental perturbations. Progresses have been made from experimental global screenings, topological and engineering studies. However, there are so far few studies of why the network should be robust and perform biological functions from global physical perspectives. In this work, we will explore the global properties of the network from physical perspectives. The aim of this work is to develop a conceptual framework and quantitative physical methods to study the global nature of the cellular network. The main conclusion of this presentation is that we uncovered the underlying energy landscape for several small cellular networks such as MAPK signal transduction network and gene regulatory networks, from the experimentally measured or inferred inherent chemical reaction rates. The underlying dynamics of these networks can show bi-stable as well as oscillatory behavior. The global shapes of the energy landscapes of the underlying cellular networks we have studied are robust against perturbations of the kinetic rates and environmental disturbances through noise. We derived a quantitative criterion for robustness of the network function from the underlying landscape. It provides a natural explanation of the robustness and stability of the network for performing biological functions. We believe the robust landscape is a global universal property for cellular networks. We believe the robust landscape is a quantitative realization of Darwinian principle of natural selection at the cellular network level. It may provide a novel algorithm for optimizing the network connections, which is crucial for the cellular network design and synthetic biology. Our approach is general and can be applied to other cellular networks.

    Cellular metabolism basically consists of the conversion of chemical compounds taken up from the extracellular environment into energy (conserved in energy-rich bonds of organic phosphates) and a wide array of organic molecules serving as catalysts (enzymes), information carriers (nucleic acids), and building blocks for cellular structures such as membranes or ribosomes. Metabolic modeling aims at the construction of mathematical representations of the cellular metabolism that can be used to calculate the concentration of cellular molecules and the rates of their mutual chemical interconversion in response to varying external conditions as, for example, hormonal stimuli or supply of essential nutrients. Based on such calculations, it is possible to quantify complex cellular functions as cellular growth, detoxification of drugs and xenobiotic compounds or synthesis of exported molecules. Depending on the specific questions to metabolism addressed, the methodological expertise of the researcher, and available experimental information, different conceptual frameworks have been established, allowing the usage of computational methods to condense experimental information from various layers of organization into (self-) consistent models. Here, we briefly outline the main conceptual frameworks that are currently exploited in metabolism research.

    Full Text Available The inclusion of psychological indicators in survey research has become more common because they offer the possibility of explaining much of the variance in sociological variables. The Big Five personality dimensions in particular are often used to explain opinions, attitudes, and behavior. However, the short versions of the Big Five Inventory (BFI-S were developed for face-to-face surveys. Studies have shown distortions in the identification of the Big Five factor structure in subsamples of older respondents in landline telephone surveys. We applied the same BFI-S but with a shorter rating scale in a telephone survey with two subsamples (landline and mobile phone. Using exploratory structural equation modeling (ESEM, we identified the Big Five structure in the subsamples and the age groups. This finding leads us to conclude that the BFI-S is a powerful means of including personality characteristics in telephone surveys.

Previous research identifying factors influencing adherence has focused primarily on broad, population-based approaches. Identifying specific barriers for an individual is more useful in designing meaningful targeted interventions. Using customized telephonic outreach, we examined specific patient-reported barriers influencing hypertensive patients' nonadherence to medication in order to identify targeted interventions.Methods: A telephone survey of 8692 nonadherent hypertensive patients was conducted. The patient sample comprised health plan members with at least two prescriptions for antihypertensive medications in 2008. The telephone script was based on the "target" drug associated with greatest nonadherence (medication possession ratio [MPR] <80% during the four-month period preceding the survey.Results: The response rate was 28.2% of the total sample, representing 63.8% of commercial members and 37.2% of Medicare members. Mean age was 63.4 years. Mean MPR was 61.0% for the target drug. Only 58.2% of Medicare respondents and 60.4% of commercial respondents reported "missing a dose of medication". The primary reason given was "forgetfulness" (61.8% Medicare, 60.8% commercial, followed by "being too busy" (2.7% Medicare, 18.5% commercial and "other reasons" (21.9% Medicare, 8.1% commercial including travel, hospitalization/sickness, disruption of daily events

    Full Text Available Background: Mobile telephones belong to the most frequently used personal devices. In their surroundings they produce the electromagnetic field (EMF, in which exposure range there are not only users but also nearby bystanders. The aim of the investigations and EMF measurements in the vicinity of phones was to identify the electric field levels with regard to various working modes. Material and methods: Twelve sets of DECT (digital enhanced cordless telecommunications cordless phones (12 base units and 15 handsets, 21 mobile telephones produced by different manufactures, and 16 smartphones in various applications, (including multimedia in the conditions of daily use in living rooms were measured. Measurements were taken using the point method in predetermined distances of 0.05–1 m from the devices without the presence of users. Results: In the vicinity of DECT cordless phone handsets, electric field strength ranged from 0.26 to 2.30 V/m in the distance of 0.05 m – 0.18–0.26 V/m (1 m. In surroundings of DECT cordless telephones base units the values of EMF were from 1.78–5.44 V/m (0.05 m to 0.19– 0.41 V/m (1 m.

    Faundez-Zanuy, Marcos; Lucena-Molina, Jose J; Hagmüller, Martin

    2010-07-01

    In this article, the authors discuss the problem of forensic authentication of digital audio recordings. Although forensic audio has been addressed in several articles, the existing approaches are focused on analog magnetic recordings, which are less prevalent because of the large amount of digital recorders available on the market (optical, solid state, hard disks, etc.). An approach based on digital signal processing that consists of spread spectrum techniques for speech watermarking is presented. This approach presents the advantage that the authentication is based on the signal itself rather than the recording format. Thus, it is valid for usual recording devices in police-controlled telephone intercepts. In addition, our proposal allows for the introduction of relevant information such as the recording date and time and all the relevant data (this is not always possible with classical systems). Our experimental results reveal that the speech watermarking procedure does not interfere in a significant way with the posterior forensic speaker identification.

    A telephone survey of farmers was conducted to determine current internal parasite control practices on sheep farms in Spain; the farmers were interviewed by their veterinarians. Anthelmintic choice was largely on veterinary advice and dominated by benzimidazoles and macrocyclic lactones. Anthelmintic rotation was separated into: no rotation (42% of farms); annual rotation (36%); rotate within year (20%); and rotate every second year (2%). The mean annual number of treatments varied subtly by region; ewes and rams 1.6-2.1, replacement lambs 1.7-2.1. Anthelmintics are administered primarily during spring and early summer (47% of treatments), and autumn (41%). Thirty-two percent of farmers introduced sheep to their properties and more than half did not quarantine drench the arrivals.

    Light, Patricia A; Hupcey, Judith E; Clark, Mary Beth

    2005-12-01

    Nursing telephone triage is a mechanism whereby parents call for advice and referrals. One common call in pediatrics concerns children's fever, which may be managed at home. Giving parents proper advice may avoid unnecessary visits. This study investigated whether home-care advice given by nurses changed parents' original preference for care. Data were collected using an existing database to determine parents' preference for location of care before and actual location of care after a call. Of the 110 calls, 73 parents wanted a physician or emergency department visit but 53 followed nursing advice for home care. Findings suggest that although most parents wanted to have their child seen, a majority followed nursing advice for home care.

    The purpose of this study was to test an intervention to increase mammography screening in women 51-75 years of age who had not received a mammogram in the last 15 months. A total of 1681 women were randomized to (1) a mailed tailored interactive DVD, (2) a computer-tailored telephone counseling, or (3) usual care. Women with income below US$75,000 who were in the interactive DVD group had significantly more mammograms than women in usual care. Women with income above US$75,000 had significantly fewer mammograms than women with income less than US$75,000 regardless of group. Further investigation is needed to understand why women with income above US$75,000 did not show the same benefit of the intervention.

    OBJECTIVE: To preliminarily evaluate telephone-delivered motivational enhancement therapy (MET) in motivating unadjudicated and nontreatment seeking intimate partner violence (IPV) perpetrators, who also use substances, to self-refer into treatment. METHOD: 124 adult men were recruited via a multimedia marketing campaign and were randomly assigned to the intervention (MET) or comparison group following a baseline assessment. Participants in the MET condition received a personalized feedback report on their IPV and substance-use behaviors, consequences, and social norms beliefs. RESULTS: Results supported the likely effectiveness of MET in short-term reduction of IPV behavior, increasing motivation for treatment seeking, and changing perceived norms for IPV and substance abuse (SA). CONCLUSIONS: Applications for brief MET interventions to facilitate voluntary treatment entry among substance-using IPV perpetrators are discussed.

    This paper presents Dialogos, a real-time system for human-machine spoken dialogue on the telephone in task-oriented domains. The system has been tested in a large trial with inexperienced users and it has proved robust enough to allow spontaneous interactions both to users which get good recognition performance and to the ones which get lower scores. The robust behavior of the system has been achieved by combining the use of specific language models during the recognition phase of analysis, the tolerance toward spontaneous speech phenomena, the activity of a robust parser, and the use of pragmatic-based dialogue knowledge. This integration of the different modules allows to deal with partial or total breakdowns of the different levels of analysis. We report the field trial data of the system and the evaluation results of the overall system and of the submodules.

    This paper sets out to investigate physicians' perceptions and usage regarding a new mobile medical information system in a pilot trial in the Finnish healthcare sector. Two sets of data were gathered in June and October 2003 by telephone interviews. The physicians interviewed had positive perceptions of the mobile system, and started to use it frequently in their work. They showed few negative experiences of using a Nokia Communicator. They favoured using mobile technology as a way to improve spreading medical knowledge. The main contents of the system, the Evidence-Based Medical Guidelines and the Pharmaca Fennica (the pharmacopoeia), were crucial for using the system. Some differences in physicians' behaviour across time were also found. Implications for system improvement are discussed.

    We approach the problem of forecasting the load of incoming calls in a cell of a mobile network using Echo State Networks. With respect to previous approaches to the problem, we consider the inclusion of additional telephone records regarding the activity registered in the cell as exogenous variables, by investigating their usefulness in the forecasting task. Additionally, we analyze different methodologies for training the readout of the network, including two novel variants, namely ν-SVR and an elastic net penalty. Finally, we employ a genetic algorithm for both the tasks of tuning the parameters of the system and for selecting the optimal subset of most informative additional time-series to be considered as external inputs in the forecasting problem. We compare the performances with standard prediction models and we evaluate the results according to the specific properties of the considered time-series.

    Full Text Available This paper presents an experimental study on the impact of telephone channels on the accuracy of automatic speaker recognition. Speaker models and the design of the recognizer used in this study are based on Hidden Markov models. In order to simulate telephonequality speech signals, several experimental conditions were introduced taking two control factors into consideration: the type of the applied codec and the probability of transmission errors. In addition, the impact of echo signals – that are often present in Internet telephony – on the accuracy of automatic speaker recognition systems is considered. Finally, the paper provides a brief overview of several methodologies for the adaptation of the recognizer to the expected environmental conditions that may enhance the robustness of the speaker recognizer.

    In the prevailing cellular environment, it is important to provide the resources for the fluctuating traffic demand exactly in the place and at the time where and when they are needed. In this paper, we explored the ability of hierarchical cellular structures with inter layer reuse to increase the capacity of mobile communication network by applying total frequency hopping (T-FH) and adaptive frequency allocation (AFA) as a strategy to reuse the macro and micro cell resources without frequency planning in indoor pico cells [11]. The practical aspects for designing macro- micro cellular overlays in the existing big urban areas are also explained [4]. Femto cells are inducted in macro / micro / pico cells hierarchical structure to achieve the required QoS cost effectively.

    Full Text Available Diabetes mellitus is one of the most common non-communicable diseases globally, labeled as the greatest healthcare challenge according to the World Health Organization and the International Diabetes Federation. This complex disease requires the involvement of multidisciplinary teams to reduce the risk and impact of long-term diabetes complications through intensive monitoring, education and lifestyle modifications with a great emphasis on promoting self-care. A brief and cost-effective interventions to improve diabetes self care management are needed. This study evaluated the effect of “educational” telephone intervention delivered by nurse specialist on glycemic control “Glyclated hemoglobin A1c”, and diabetes self-care management for patients with type 2 diabetes followed-up by a nurse-led cardiovascular disease management program of a tertiary hospital within the Kingdom of Saudi Arabia. This quantitative descriptive and qauzi-experimental study was conducted over three months, included 60 adult patients diagnosed with type 2 diabetes who were randomly assigned to intervention or control group. Participants within the intervention group received usual care and six educational phone calls promoting them to improve their diabetic self-care activities. Patients within the control arm continued to receive their usual care only. The telephone follow-up intervention increased frequency of exercise and foot care, improved diet and adherence to anti-diabetes medication. Modest improvement was detected on the glycemic control and home glucose monitoring. As a conclusion, the study indicated positive effect of the intervention on glycemic control and self-care management. Multi-centers and longitudinal studies with larger sample size are recommended for future studies.

    Full Text Available OBJECTIVE: Willingness to participate in obesity prevention programs is low; underlying reasons are poorly understood. We evaluated reasons for (nonparticipating in a novel telephone-based obesity prevention program for overweight children and their families. METHOD: Overweight children and adolescents (BMI>90(th percentile aged 3.5-17.4 years were screened via the CrescNet database, a representative cohort of German children, and program participation (repetitive computer aided telephone counseling was offered by their local pediatrician. Identical questionnaires to collect baseline data on anthropometrics, lifestyle, eating habits, sociodemographic and psychosocial parameters were analyzed from 433 families (241 participants, 192 nonparticipants. Univariate analyses and binary logistic regression were used to identify factors associated with nonparticipation. RESULTS: The number of overweight children (BMI>90(th percentile was higher in nonparticipants than participants (62% vs. 41.1%,p97(th percentile was higher in participants (58.9% vs.38%,p<0.001. Participating girls were younger than boys (8.8 vs.10.4 years, p<0.001. 87.3% and 40% of participants, but only 72.2% and 24.7% of nonparticipants, respectively, reported to have regular breakfasts (p = 0.008 and 5 regular daily meals (p = 0.003. Nonparticipants had a lower household-net-income (p<0.001, but higher subjective physical wellbeing than participants (p = 0.018 and believed that changes in lifestyle can be made easily (p = 0.05. CONCLUSION: An important reason for nonparticipation was non-awareness of their child's weight status by parents. Nonparticipants, who were often low-income families, believed that they already perform a healthy lifestyle and had a higher subjective wellbeing. We hypothesize that even a low-threshold intervention program does not reach the families who really need it.

    Telephone nurse lines help callers to select the most appropriate site and level of care for acute conditions. We examined whether compliance with nurse recommendations was associated with lower average health care expenditure, and identified the employer characteristics associated with higher than average savings. Telephone calls to a nurse-led help line made by commercial health plan members who worked for large employers were identified. The callers' intention before calling and the nurse recommendation regarding site/level of care were recorded. Compliance was determined using medical claims during a 30-day post-call observation period and was based on adherence to nurse recommendations. A total of 132,509 calls during 2012 were identified for the study. Nurse recommendations were that 31% of the callers seek a higher level of care than mentioned at the start of the call, 25% use a lower level of care and 44% pursue their originally intended level of care. After regression-based adjustment, the average medical expenditures were compared between compliers and non-compliers. Overall, 57% of callers were compliant with nurse recommendations. The average expenditures were $328 lower among compliant callers. A logistic regression analysis identified employer characteristics positively associated with achieving higher than average savings. These were having a low employee-to-dependent ratio, a headquarters in the Western region of the US, a low prospective health risk score, and participation by the employer in a targeted communication campaign. Compliance with the triage recommendations resulted in lower average health care expenditures, and several characteristics were positively associated with achieving higher savings.

    Objectives Little is known about pet-related injuries in Asian populations. This study primarily aimed to investigate the incidence rate of pet-related household injuries in Hong Kong, an urban Chinese setting. Setting Cantonese-speaking non-institutionalised population of all ages in Hong Kong accessible by telephone land-line. Participants A total of 43 542 telephone numbers were dialled and 6570 residents successfully completed the interviews. Primary and secondary outcome measures Data of pet-related household injuries in the previous 12 months, pet ownership and socio-demographic characteristics were collected with a questionnaire. Direct standardisation of the incidence rates of pet-related household injuries by gender and age to the 2009 Hong Kong Population Census was estimated. Univariate and multivariate analyses were performed to estimate risks of socio-demographic factors and pet ownership for the injury. Results A total of 84 participants experienced pet-related household injuries in the past 12 months, with an overall person-based incidence rate of 1.28%. The majority of the victims were injured once (69.6%). Cats (51.6%) were the most common pets involved. Pet owners were at an extremely higher risk after controlling for other factors (adjusted OR: 52.0, 95% CI 22.1 to 98.7). Females, the unmarried, those with higher monthly household income and those living in lower-density housing were more likely to be injured by pets. Conclusions We project a pet-related household injury incidence rate of 1.24% in the general Hong Kong population, with 86 334 residents sustaining pet-related injuries every year. Pet ownership puts people at extremely high risk, especially the unmarried. Further studies should focus on educating pet owners to reduce pet-related injuries in urban Greater China. PMID:28110284

    Full Text Available Background: Postpartum depression (PPD is one public health issue that affects both maternal and child health. This research studies the effect of health volunteers’ telephonebased support on decreasing PPD. Materials and Methods: This randomized controlled trial evaluated 203 women who had uncomplicated deliveries. The women completed the Edinburg Postnatal Depression Scale (EPDS, 10 to 15 days after childbirth in order to be assessed for pre-trial depression scores. The cut-off point for depression was considered to be a score of >10. We randomly assigned 54 eligible mothers (n=27 per group with mild and moderate depression to the intervention and control groups. In both groups, mothers received routine postpartum care. The intervention group additionally received telephone support from health volunteers. A questionnaire was used to gather demographic and obstetric information. By the end of the 6th week, mothers completed the EPDS to be reassessed for depression after intervention. Data were analyzed using the chi-square, Fisher’s exact, t- and paired t tests. Results: The mean depression scores before intervention (10 to 15 days after childbirth in the intervention and control groups did not significantly differ (P=0.682. Depression scores of the intervention and control groups showed a significant difference after 6 weeks (P=0.035. In addition, there was a significant decrease in depression for the intervention and control groups (P=0.045. Conclusion: Health volunteer telephone-based support effectively decreased PPD and may be beneficial to women with symptoms of mild and moderate PPD (Registration number: IRCT201202159027N1.

    Full Text Available Background: Postpartum depression (PPD is one public health issue that affects both maternal and child health. This research studies the effect of health volunteers’ telephonebased support on decreasing PPD. Materials and Methods: This randomized controlled trial evaluated 203 women who had uncomplicated deliveries. The women completed the Edinburg Postnatal Depression Scale (EPDS, 10 to 15 days after childbirth in order to be assessed for pre-trial depression scores. The cut-off point for depression was considered to be a score of >10. We randomly assigned 54 eligible mothers (n=27 per group with mild and moderate depression to the intervention and control groups. In both groups, mothers received routine postpartum care. The intervention group additionally received telephone support from health volunteers. A questionnaire was used to gather demographic and obstetric information. By the end of the 6th week, mothers completed the EPDS to be reassessed for depression after intervention. Data were analyzed using the chi-square, Fisher’s exact, t- and paired t tests. Results: The mean depression scores before intervention (10 to 15 days after childbirth in the intervention and control groups did not significantly differ (P=0.682. Depression scores of the intervention and control groups showed a significant difference after 6 weeks (P=0.035. In addition, there was a significant decrease in depression for the intervention and control groups (P=0.045. Conclusion: Health volunteer telephone-based support effectively decreased PPD and may be beneficial to women with symptoms of mild and moderate PPD (Registration number: IRCT201202159027N1.

    2016-10-01

    This paper proposes an application of the Infinite Unit Axiom and grossone, introduced by Yaroslav Sergeyev (see [7] - [12]), to the development and classification of one and two-dimensional cellular automata. By the application of grossone, new and more precise nonarchimedean metrics on the space of definition for one and two-dimensional cellular automata are established. These new metrics allow us to do computations with infinitesimals. Hence configurations in the domain space of cellular automata can be infinitesimally close (but not equal). That is, they can agree at infinitely many places. Using the new metrics, open disks are defined and the number of points in each disk computed. The forward dynamics of a cellular automaton map are also studied by defined sets. It is also shown that using the Infinite Unit Axiom, the number of configurations that follow a given configuration, under the forward iterations of cellular automaton maps, can now be computed and hence a classification scheme developed based on this computation.

    Full Text Available Technological advancement in mobile telephony from 1G to 3G, 4G and 5G has a very axiomatic fact that made an entire world a global village. The cellular system employs a different design approach and technology that most commercial radio and television system use. In the cellular system, the service area is divided into cells and a transmitter is designed to serve an individual cell. The system seeks to make efficient use of available channels by using low-power transmitters to allow frequency reuse at a smaller distance. Maximizing the number of times each channel can be reused in a given geographical area is the key to an efficient cellular system design. During the past three decades, the world has seen significant changes in telecommunications industry. There have been some remarkable aspects to the rapid growth in wireless communications, as seen by the large expansion in mobile systems. This paper focuses on “Past, Present & Future of Cellular Telephony” and some light has been thrown upon the technologies of the cellular systems, namely 1G, 2G, 2.5G, 3G and future generations like 4G and 5G systems as well.

    2016-10-01

    Developing new therapeutic strategies for Parkinson's disease requires cellular models. Current models reproduce the two most salient changes found in the brains of patients with Parkinson's disease: The degeneration of dopaminergic neurons and the existence of protein aggregates consisting mainly of α-synuclein. Cultured cells offer many advantages over studying Parkinson's disease directly in patients or in animal models. At the same time, the choice of a specific cellular model entails the requirement to focus on one aspect of the disease while ignoring others. This article is intended for researchers planning to use cellular models for their studies. It describes for commonly used cell types the aspects of Parkinson's disease they model along with technical advantages and disadvantages. It might also be helpful for researchers from other fields consulting literature on cellular models of Parkinson's disease. Important models for the study of dopaminergic neuron degeneration include Lund human mesencephalic cells and primary neurons, and a case is made for the use of non-dopaminergic cells to model pathogenesis of non-motor symptoms of Parkinson's disease. With regard to α-synuclein aggregates, this article describes strategies to induce and measure aggregates with a focus on fluorescent techniques.

    Alzheimer's disease (AD) is the most common form of neurodegenerative disease. A characteristic feature of the disease is the presence of amyloid-β (Aβ) which either in its soluble oligomeric form or in the plaque-associated form is causally linked to neurodegeneration. Aβ peptide is liberated from the membrane-spanning -amyloid precursor protein by sequential proteolytic processing employing β- and γ-secretases. All these proteins involved in the production of Aβ peptide are membrane associated and hence, membrane trafficking and cellular compartmentalization play important roles. In this review, we summarize the key cellular events that lead to the progression of AD.

    2014-10-01

    No studies to date have examined the effect of counselor techniques on smoking cessation over the course of treatment. To address this gap, we examined the degree to which the use of specific Acceptance and Commitment Therapy (ACT) counseling techniques in a given session predicted smoking cessation reported at the next session. The data came from the ACT arm of a randomized controlled trial of a telephone-delivered smoking cessation intervention. Trained raters coded 139 counseling sessions across 44 participants. The openness, awareness and activation components of the ACT model were rated for each telephone counseling session. Multilevel logistic regression models were used to estimate the predictive relationship between each component during any given telephone session and smoking cessation at the following telephone session. For every 1-unit increase in counselors' use of openness and awareness techniques there were 42% and 52% decreases in the odds of smoking at the next counseling session, respectively. However, there was no significant predictive relationship between counselors' use of activation techniques and smoking cessation. Overall, results highlight the theoretical and clinical value of examining therapists' techniques as predictors of outcome during the course of treatment.

    The ESTEEM trial was a randomised-controlled trial of telephone triage consultations in general practice. We conducted exploratory analyses on data from 9154 patients from 42 UK general practices who returned a questionnaire containing self-reported ratings of satisfaction with care following a request for a same-day consultation. Mode of care was identified through case notes review. There were seven main types: a GP face-to-face consultation, GP or nurse telephone triage consultation with no subsequent same day care, or a GP or nurse telephone triage consultation with a subsequent face-to-face consultation with a GP or a nurse. We investigated the contribution of mode of care to patient satisfaction and distance between the patient׳s home and the practice as a potential moderating factor. There was no overall association between patient satisfaction and distance from practice. However, patients managed by a nurse telephone consultation showed lowest levels of satisfaction, and satisfaction for this group of patients increased the further they lived from the practice. There was no association between any of the other modes of management and distance from practice.

    2014-12-01

    A systematic review of the literature on telephone or internet-based support for smoking, alcohol use or gambling was performed. Studies were included if they met the following criteria: The design being a randomized control trail (RCT), focused on effects of telephone or web based interventions, focused on pure telephone or internet-based self-help, provided information on alcohol or tobacco consumption, or gambling behavior, as an outcome, had a follow-up period of at least 3months, and included adults. Seventy-four relevant studies were found; 36 addressed the effect of internet interventions on alcohol consumption, 21 on smoking and 1 on gambling, 12 the effect of helplines on smoking, 2 on alcohol consumption, and 2 on gambling. Telephone helplines can have an effect on tobacco smoking, but there is no evidence of the effects for alcohol use or gambling. There are some positive findings regarding internet-based support for heavy alcohol use among U.S. college students. However, evidence on the effects of internet-based support for smoking, alcohol use or gambling are to a large extent inconsistent.

    Background and Purpose The NINDS-CSN vascular cognitive impairment (VCI) Harmonization working group proposed a brief cognitive protocol for screening of VCI. We investigated the validity, reliability and feasibility of the Montreal Cognitive Assessment 5-minute protocol (MoCA 5-min protocol) administered over the telephone. Methods Four items examining attention, verbal learning and memory, executive functions/language and orientation were extracted from the MoCA to form the MoCA 5-min protocol. One hundred and four patients with stroke or TIA, including 53 with normal cognition (CDR 0) and 51 with cognitive impairment (CDR 0.5 or 1), were administered the MoCA in clinic and a month later, the MoCA 5-min protocol over the telephone. Results Administration of the MoCA 5-min protocol took five minutes over the telephone. Total score of the MoCA 5-min protocol correlated negatively with age (r=-0.36, p0.05 for difference; Cohen's d for group difference 0.801.13). It differentiated cognitively impaired patients with executive domain impairment from those without (AUC=0.89, p<0.001; Cohen's d=1.7 for group difference). 30-day test-retest reliability was excellent (Intraclass correlation coefficient=0.89). Conclusions The MoCA 5-min protocol is a free, valid and reliable cognitive screen for stroke and TIA. It is brief and highly feasible for telephone administration. PMID:25700290

    Full Text Available Abstract Background Given the increasing use of telephone consultation it is important to determine the factors which influence the length of a telephone consultation. Method Analysis of 128717 telephone consultations during January to December 2011 to a National Health Service (NHS out-of-hours primary care service provider in Shropshire and Telford and Powys, England, involving 102 General Practitioners (GPs and 36 Nurse Practitioners (NPs. Telephone consultation conclude with one of three outcomes – advice only, the patient is invited to a face-to-face consultation with a GP or NP at a nearby health centre (known as a base visit or the patient is visited at home by a GP or NP (known as home visit. Call length was analysed by these outcomes. Results The overall mean call length was 7.78 minutes (standard deviation (SD 4.77. Calls for advice only were longest (mean 8.11 minutes, SD 5.17, followed by calls which concluded with a base visit (mean 7.36 minutes, SD 4.08 or a home visit (mean 7.16 minutes, SD 4.53. Two primary factors influenced call length. Calls by GPs were shorter (mean 7.15 minutes, SD 4.41 than those by NPs (mean 8.74 minutes, SD 5.31 and calls designated as a mental health call were longer (mean 11.16 minutes, SD 4.75 than all other calls (mean 7.73 minutes, SD 7.7. Conclusions Telephone consultation length in the out-of-hours setting is influenced primarily by whether the clinician is a GP or a NP and whether the call is designated as a mental health call or not. These findings suggest that appropriate attempts to reduce the length of the telephone consultations should focus on these two areas, although the longer consultation length associated with NPs is offset to some extent by their lower employment costs compared to GPs. Nonetheless the extent to which the length of a telephone consultation impacts on subsequent use of the health service and correlates with quality and safety remains unclear.

    Although psychiatric crises are very common in people with mental illness, little is known about consumer perceptions of mental health crisis care. Given the current emphasis on recovery-oriented approaches, shared decision-making, and partnering with consumers in planning and delivering care, this knowledge gap is significant. Since the late 1990s, access to Australian mental health services has been facilitated by 24/7 telephone-based mental health triage systems, which provide initial psychiatric assessment, referral, support, and advice. A significant proportion of consumers access telephone-based mental health triage services in a state of crisis, but to date, there has been no published studies that specifically report on consumer perceptions on the quality and effectiveness of the care provided by these services. This article reports on a study that investigated consumer perceptions of accessing telephone-based mental health triage services. Seventy-five mental health consumers participated in a telephone interview about their triage service use experience. An eight-item survey designed to measure the responsiveness of mental health services was used for data collection. The findings reported here focus on the qualitative data produced in the study. Consumer participants shared a range of perspectives on telephone-based mental health triage that provide invaluable insights into the needs, expectations, and service use experiences of consumers seeking assistance with a mental health problem. Consumer perceptions of crisis care have important implications for practice. Approaches and interventions identified as important to quality care can be used to inform educational and practice initiatives that promote person-centred, collaborative crisis care.

  13. On Cellular MIMO Channel Capacity

    Science.gov (United States)

    Adachi, Koichi; Adachi, Fumiyuki; Nakagawa, Masao

    To increase the transmission rate without bandwidth expansion, the multiple-input multiple-output (MIMO) technique has recently been attracting much attention. The MIMO channel capacity in a cellular system is affected by the interference from neighboring co-channel cells. In this paper, we introduce the cellular channel capacity and evaluate its outage capacity, taking into account the frequency-reuse factor, path loss exponent, standard deviation of shadowing loss, and transmission power of a base station (BS). Furthermore, we compare the cellular MIMO downlink channel capacity with those of other multi-antenna transmission techniques such as single-input multiple-output (SIMO) and space-time block coded multiple-input single-output (STBC-MISO). We show that the optimum frequency-reuse factor F that maximizes 10%-outage capacity is 3 and both 50%- and 90%-outage capacities is 1 irrespective of the type of multi-antenna transmission technique, where q%-outage capacity is defined as the channel capacity that gives an outage probability of q%. We also show that the cellular MIMO channel capacity is always higher than those of SIMO and STBC-MISO.

    Depressive symptoms negatively impact the lives of HIV-infected individuals and are correlated with faster progression to AIDS. Our embedded mixed methods study examined and described the effects of telephone support on depressive symptoms in a sample of HIV-infected pregnant Thai women. HIV-infected pregnant Thai women (n = 40) were randomly assigned to either the control or the intervention group. A registered nurse provided telephone support to the intervention group. Depressive symptoms were measured at three points in both groups. In-depth interviews were conducted at Time 2 and Time 3. Results show that depressive symptoms in the intervention group decreased over time. Qualitative results describe how telephone support can work, but also reveal that telephone support did not work for everyone. We recommend that a larger mixed methods study be conducted to examine the effects of telephone support on depressive symptoms among HIV-infected women, including the costs and benefits of such support.

The aim of this study is to describe lifestyle and biomedical associations as possible causes of erectile dysfunction (ED, prostate disease (PD, lower urinary tract symptoms (LUTS and perceived symptoms of androgen deficiency (pAD in a representative population of middle-aged and older men, using the Men in Australia Telephone Survey (MATeS. Methods A representative sample (n = 5990 of men aged 40+ years, stratified by age and State, was contacted by random selection of households, with an individual response rate of 78%. All men participated in a 20-minute computer-assisted telephone interview exploring general and reproductive health. Associations between male reproductive health disorders and lifestyle and biomedical factors were analysed using multivariate logistic regression (odds ratio [95% confidence interval]. Variables studied included age, body mass index, waist circumference, smoking, alcohol consumption, physical activity, co-morbid disease and medication use for hypertension, high cholesterol and symptoms of depression. Results Controlling for age and a range of lifestyle and co-morbid exposures, sedentary lifestyle and being underweight was associated with an increased likelihood of ED (1.4 [1.1-1.8]; 2.9 [1.5-5.8], respectively and pAD (1.3 [1.1-1.7]; 2.7 [1.4-5.0], respectively. Diabetes and cardiovascular disease were both associated with ED, with hypertension strongly associated with LUTS and pAD. Current smoking (inverse association and depressive symptomatology were the only variables independently associated with PD. All reproductive disorders showed consistent associations with depression (measured either by depressive symptomatology or medication use in both age-adjusted and multivariate analyses. Conclusion A range of lifestyle factors, more often associated with chronic disease, were

    In the United States, Spanish-speaking patients with diabetes often receive inadequate dietary counseling. Providing language and culture-concordant dietary counseling on an ongoing basis is critical to diabetes self-care. To determine if automated telephone nutrition support (ATNS) counseling could help patients improve glycemic control by duplicating a successful pilot in Mexico in a Spanish-speaking population in Oakland, California. A prospective randomized open-label trial with blinded endpoint assessment (PROBE) was performed. The participants were seventy-five adult patients with diabetes receiving care at a federally qualified health center in Oakland, California. ATNS, a computerized system that dialed patients on their phones, prompted them in Spanish to enter (via keypad) portions consumed in the prior 24 hours of various cultural-specific dietary items, and then provided dietary feedback based on proportion of high versus low glycemic index foods consumed. The control group received the same ATNS phone calls 14 weeks after enrollment. The primary outcome was hemoglobin A1c % (A1c) 12 weeks following enrollment. Participants had no significant improvement in A1c (–0.3% in the control arm, –0.1% in the intervention arm, P = .41 for any difference) or any secondary parameters. In our study, an ATNS system did not improve diabetes control in a Spanish-speaking population in Oakland. PMID:25239122

    This presentation discussed a field test conducted to develop new protection criteria for telephone cables serving substations. Most distribution substations in rural areas are not linked to Hydro-Quebec's telecommunication network. However, the cost advantage of using wireless or fiber optic links cannot be justified despite the fact that more than 200 sites are in need of additional electrical protection. The field tests were conducted at 2 rural 120/25 kV substations in order to determine reduction factors and grounding for cable sheaths. Faults on the distribution line were examined as well as high voltage (HV) faults at the substation. Approximately 440 current injections were applied over a testing period of 24 days. Voltage measurements were conducted for an area up to 100 km{sup 2} around the substations. The study showed that transferred voltage along metallic links and mutual resistance between the ground electrodes influenced soil voltage profiles. Transfer voltages travelled more than 5 km in rural areas. Grounding reference for customers reached more than 70 per cent of the GPR value. The study showed that a reduction factor of at least 40 per cent can be used for high voltage faults in MGN distribution substations. Power line sheaths can be grounded if sheath temperature can be limited to 110 degrees C. An updated Hydro-Quebec cable protection policy was included. tabs., figs.

    Full Text Available Abstract Background Irish teenagers demonstrate high rates of drunkenness and there has been a progressive fall in age of first drinking in recent decades. International research indicates that parents exert substantial influence over their teenager's drinking. We sought to determine the attitudes and behaviours of Irish parents towards drinking by their adolescent children. Methods We conducted a telephone survey of a representative sample of of 234 parents who had a teenager aged between 13 and 17 years. Results Six per cent reported that they would be unconcerned if their son or daughter was to binge drink once per month. On the issue of introducing children to alcohol in the home, 27% viewed this as a good idea while 63% disagreed with this practice. Eleven per cent of parents reported that they had given a drink to their teenager at home. Parents who drank regularly themselves, who were from higher socio-demographic groups and who lived in the east of Ireland demonstrated more permissive attitudes to teenage drinking. Conclusions We found no evidence of widespread permissive attitudes and behaviours among Irish parents. Given that parental influences have been demonstrated to exert substantial impact on teenage drinking, it may be possible to harness the concerns of Irish parents more effectively to reverse the trends of escalating alcohol related harm in Ireland.

    Hotline callers do not always have suicidal ideation and previous studies have noted that the rate of such callers is limited. Crisis hotline counselors must be able to identify high-risk callers in order to provide appropriate support. This study investigated the characteristics of Japanese crisis hotline callers in 2012 (N = 541,694) and is the first to analyze crisis hotline data for all parts of Japan over 1 year. About 14% of the callers had suicidal ideation and 6% had a history of attempted suicide. The odds ratio for suicidal ideation among those with a history of attempted suicide was 15.5. The suicidal ideation rate was much smaller compared to previous studies in other countries. There is a psychological barrier that must be broken for high-risk people to use support hotlines. In addition, attempted suicide is a strong exclusive predisposing factor for death due to suicide; therefore, counselors should pay careful attention to callers with a history of attempted suicide. The characteristics of Japanese crisis hotline callers and the features of suicidal ideation revealed in the present study are expected to be useful in developing telephone crisis hotline strategies.

    Full Text Available Abstract Background While a definitive genetic test for Hereditary Prostate Cancer (HPC is not yet available, future HPC risk testing may become available. Past survey data have shown high interest in HPC testing, but without an in-depth analysis of its underlying rationale to those considering it. Methods Telephone computer-assisted interviews of 400 men were conducted in a large metropolitan East-coast city, with subsequent development of psychometric scales and their correlation with intention to receive testing. Results Approximately 82% of men interviewed expressed that they "probably" or "definitely" would get genetic testing for prostate cancer risk if offered now. Factor analysis revealed four distinct, meaningful factors for intention to receive genetic testing for prostate cancer risk. These factors reflected attitudes toward testing and were labeled "motivation to get testing," "consequences and actions after knowing the test result," "psychological distress," and "beliefs of favorable outcomes if tested" (α = 0.89, 0.73, 0.73, and 0.60, respectively. These factors accounted for 70% of the total variability. The domains of motivation (directly, consequences (inversely, distress (inversely, and positive expectations (directly all correlated with intention to receive genetic testing (p Conclusions Men have strong attitudes favoring genetic testing for prostate cancer risk. The factors most associated with testing intention include those noted in past cancer genetics studies, and also highlights the relevance in considering one's motivation and perception of positive outcomes in genetic decision-making.

    A cross-sectional telephone survey was conducted in Denmark throughout 2009 to determine the incidence of acute gastrointestinal illness (AGI). Using the Danish population register, a random population sample stratified by gender and age groups was selected and mobile or landline phone numbers found. Representative numbers of interviews were performed by gender, age group and month. A recently proposed international case definition of AGI, including cases with diarrhoea and/or vomiting in a 4-week recall period, was used. A total of 1853 individuals were included and 206 (11·1%) fulfilled the case definition; 78% reported diarrhoea. This corresponds to an overall standardized incidence rate of 1·4 (95% CI 1·2-1·6) episodes of AGI per person-year. The incidence rate was generally higher in the younger age groups; only being 2·3, 1·9 and 0·80 per person-year in the 0-9, 10-39 and ≥40 years age groups, respectively. The incidence rate estimates were considerably higher when calculated from shorter recall periods.

    Full Text Available Abstract Background Brief screening tests have been developed to measure cognitive performance and dementia, yet they measure limited cognitive domains and often lack construct validity. Neuropsychological assessments, while comprehensive, are too costly and time-consuming for epidemiological studies. This study's aim was to develop a psychometrically valid telephone administered test of cognitive function in aging. Methods Using a sequential hierarchical strategy, each stage of test development did not proceed until specified criteria were met. The 30 minute Cognitive Assessment of Later Life Status (CALLS measure and a 2.5 hour in-person neuropsychological assessment were conducted with a randomly selected sample of 211 participants 65 years and older that included equivalent distributions of men and women from ethnically diverse populations. Results Overall Cronbach's coefficient alpha for the CALLS test was 0.81. A principal component analysis of the CALLS tests yielded five components. The CALLS total score was significantly correlated with four neuropsychological assessment components. Older age and having a high school education or less was significantly correlated with lower CALLS total scores. Females scored better overall than males. There were no score differences based on race. Conclusion The CALLS test is a valid measure that provides a unique opportunity to reliably and efficiently study cognitive function in large populations.

    The main purpose of this paper was to present a distributed speech interactive system built on LAN (Local area network), which integrated Automatic speech recognition (ASR), Text to speech (TTS) and Natural language perception (NLP) technologies to allow multiusers to access and converse with it concurrently. During a typical telephone based interaction, users could retrieve up-to-date stock information and call for somebody by directly speaking their name. Though there were far too many papers published to describe such system, most of them all focused on the algorithm on speech recognition rather than the architecture. Our paper was written to make for it and proposed an efficient and effective dynamic load balancing algorithm with sender active and non-preemptive concepts based on the distributed architecture and multithread concurrency in order to solve the loads allocating when multi-users accessed the system and gave rise to much burden to the servers. This paper was composed of five part: (1) an introduction about why such architecture was built; (2) an overview about the system; (3) proposed and implemented the algorithm; (4) evaluated and tested the system performance based on the architecture; and (5) a brief summary.

  6. From Non-abelian Anyons To Quantum Computation To Coin- Flipping By Telephone

    Following their divorce, Alice and Bob would like to split some of their possessions by flipping a coin. Unwilling to meet in person, and without a trusted third party, they must figure out a scheme to flip the coin over a telephone that guarantees that neither party can cheat. The preceding scenario is the traditional definition of two-party coin-flipping. In a classical setting, without limits on the available computational power, one player can always guarantee a coin-flipping victory by cheating. However, by employing quantum communication it is possible to guarantee, with only information-theoretic assumptions, that neither party can win by cheating, with a probability greater than two thirds. Along with the description of such a protocol, this thesis derives a tight lower bound on the bias for a large family of quantum weak coin-flipping protocols, proving such a protocol optimal within the family. The protocol described herein is an improvement and generalization of one examined by Spekkens and Rudolph...

    2004-01-01

    A Vector piecewise polynomial (VPP) approximation algorithm is proposed for environ-ment compensation of speech signals degraded by both additive and convolutive noises. By investi-gating the model of the telephone environment, we propose a piecewise polynomial, namely twolinear polynomials and a quadratic polynomial, to approximate the environment function precisely.The VPP is applied either to the stationary noise, or to the non stationary noise. In the first case,the batch EM is used in log-spectral domain; in the second case the recursive EM with iterativestochastic approximation is developed in cepstral domain. Both approaches are based on the mini-mum mean squared error (MMSE) sense. Experimental results are presented on the application ofthis approach in improving the performance of Mandarin large vocabulary continuous speech recog-nition (LVCSR) due to the background noises and different transmission channels (such as fixedtelephone line and GSM). The method can reduce the average character error rate (CER) by a-bout 18%.

    The avian influenza A (A/H5N1) virus has attracted the attention of governments and health organizations throughout the world because of its pandemic potential. Despite the emerging nature of A/H5N1, there is limited research on public knowledge and perceptions of this disease. This study is based on a computer-assisted telephone interviewing survey conducted in May 2006 to determine the Australian public's knowledge of A/H5N1, their willingness to engage in preventive behaviors, and their acceptance of potential messages for communication campaigns. Awareness and concern about bird flu is low (lower than a recent survey of U.S. residents). There appears to be widespread support for bird flu control measures initiated by the federal government, although less agreement regarding personal protective behaviors. Our study and those examining the severe acute respiratory syndrome epidemic suggest that governments, including the Australian government, will encounter a number of significant communication challenges in the event of a bird flu outbreak.

    2013-09-13

    We introduce composite materials made by reversibly assembling a three-dimensional lattice of mass-produced carbon fiber-reinforced polymer composite parts with integrated mechanical interlocking connections. The resulting cellular composite materials can respond as an elastic solid with an extremely large measured modulus for an ultralight material (12.3 megapascals at a density of 7.2 milligrams per cubic centimeter). These materials offer a hierarchical decomposition in modeling, with bulk properties that can be predicted from component measurements and deformation modes that can be determined by the placement of part types. Because site locations are locally constrained, structures can be produced in a relative assembly process that merges desirable features of fiber composites, cellular materials, and additive manufacturing.

    Full Text Available Abstract Background Smoking is the world's fourth most common risk factor for disease, the leading preventable cause of death, and it is associated with tremendous social costs. In the Netherlands, the smoking prevalence rate is high. A total of 27.7% of the population over age 15 years smokes. In addition to the direct advantages of smoking cessation for the smoker, parents who quit smoking may also decrease their children's risk of smoking initiation. Methods/Design A randomized controlled trial will be conducted to evaluate the effectiveness of proactive telephone counselling to increase smoking cessation rates among smoking parents. A total of 512 smoking parents will be proactively recruited through their children's primary schools and randomly assigned to either proactive telephone counselling or a control condition. Proactive telephone counselling will consist of up to seven counsellor-initiated telephone calls (based on cognitive-behavioural skill building and Motivational Interviewing, distributed over a period of three months. Three supplementary brochures will also be provided. In the control condition, parents will receive a standard brochure to aid smoking cessation. Assessments will take place at baseline, three months after start of the intervention (post-measurement, and twelve months after start of the intervention (follow-up measurement. Primary outcome measures will include sustained abstinence between post-measurement and follow-up measurement and 7-day point prevalence abstinence and 24-hours point prevalence abstinence at both post- and follow-up measurement. Several secondary outcome measures will also be included (e.g., smoking intensity, smoking policies at home. In addition, we will evaluate smoking-related cognitions (e.g., attitudes towards smoking, social norms, self-efficacy, intention to smoke in 9-12 year old children of smoking parents.

    Glycosylation is a common post-translational modification of proteins and is implicated in a variety of cellular functions including protein folding, degradation, sorting and trafficking, and membrane protein recycling. The membrane protein prestin is an essential component of the membrane-based motor driving electromotility changes (electromotility) in the outer hair cell (OHC), a central process in auditory transduction. Prestin was earlier identified to possess two N-glycosylation sites (N163, N166) that, when mutated, marginally affect prestin nonlinear capacitance (NLC) function in cultured cells. Here, we show that the double mutant prestin(NN163/166AA) is not glycosylated and shows the expected NLC properties in the untreated and cholesterol-depleted HEK 293 cell model. In addition, unlike WT prestin that readily forms oligomers, prestin(NN163/166AA) is enriched as monomers and more mobile in the plasma membrane, suggesting that oligomerization of prestin is dependent on glycosylation but is not essential for the generation of NLC in HEK 293 cells. However, in the presence of increased membrane cholesterol, unlike the hyperpolarizing shift in NLC seen with WT prestin, cells expressing prestin(NN163/166AA) exhibit a linear capacitance function. In an attempt to explain this finding, we discovered that both WT prestin and prestin(NN163/166AA) participate in cholesterol-dependent cellular trafficking. In contrast to WT prestin, prestin(NN163/166AA) shows a significant cholesterol-dependent decrease in cell-surface expression, which may explain the loss of NLC function. Based on our observations, we conclude that glycosylation regulates self-association and cellular trafficking of prestin(NN163/166AA). These observations are the first to implicate a regulatory role for cellular trafficking and sorting in prestin function. We speculate that the cholesterol regulation of prestin occurs through localization to and internalization from membrane microdomains by

  16. The insect cellular immune response

    2008-01-01

    The innate immune system of insects is divided into humoral defenses that include the production of soluble effector molecules and cellular defenses like phagocytosis and encapsulation that are mediated by hemocytes. This review summarizes current understanding of the cellular immune response. Insects produce several terminally differentiated types of hemocytes that are distinguished by morphology, molecular and antigenic markers, and function. The differentiated hemocytes that circulate in larval or nymphal stage insects arise from two sources: progenitor cells produced during embryogenesis and mesodermally derived hematopoietic organs. Regulation of hematopoiesis and hemocyte differentiation also involves several different signaling pathways. Phagocytosis and encapsulation require that hemocytes first recognize a given target as foreign followed by activation of downstream signaling and effector responses. A number of humoral and cellular receptors have been identified that recognize different microbes and multicellular parasites. In turn, activation of these receptors stimulates a number of signaling pathways that regulate different hemocyte functions. Recent studies also identify hemocytes as important sources of a number of humoral effector molecules required for killing different foreign invaders.

    Differentiation, the stepwise specialization of cells, and transdifferentiation, the apparent switching of one cell type into another, capture much of the stem cell spotlight. But dedifferentiation, the developmental reversal of a cell before it reinvents itself, is an important process too. In multicellular organisms, cellular dedifferentiation is the major process underlying totipotency, regeneration and formation of new stem cell lineages. In humans,dedifferentiation is often associated with carcinogenesis.The study of cellular dedifferentiation in animals,particularly early events related to cell fate-switch and determination, is limited by the lack of a suitable,convenient experimental system. The classic example of dedifferentiation is limb and tail regeneration in urodele amphibians, such as salamanders. Recently, several investigators have shown that certain mammalian cell types can be induced to dedifferentiate to progenitor cells when stimulated with the appropriate signals or materials. These discoveries open the possibility that researchers might enhance the endogenous regenerative capacity of mammals by inducing cellular dedifferentiation in vivo.

    Knowledge-based speech recognition systems extract acoustic cues from the signal to identify speech characteristics. For channel-deteriorated telephone speech, acoustic cues, especially those for stop consonant place, are expected to be degraded or absent. To investigate the use of knowledge-based methods in degraded environments, feature extrapolation of acoustic-phonetic features based on Gaussian mixture models is examined. This process is applied to a stop place detection module that uses burst release and vowel onset cues for consonant-vowel tokens of English. Results show that classification performance is enhanced in telephone channel-degraded speech, with extrapolated acoustic-phonetic features reaching or exceeding performance using estimated Mel-frequency cepstral coefficients (MFCCs). Results also show acoustic-phonetic features may be combined with MFCCs for best performance, suggesting these features provide information complementary to MFCCs.

    Full Text Available Purpose: Methods used to deliver and test a pharmacy-based asthma care telephonic service for an underserved, rural patient population are described. Summary: In a randomized controlled trial (RCT, the Patient And phaRmacist Telephonic Encounters (PARTE project is assessing the feasibility, acceptability, and preliminary impact of providing pharmacy-based asthma care service telephonically. The target audience is a low income patient population across a large geographic area served by a federally qualified community health center. Ninety-eight participants have been randomized to either standard care or the intervention group who received consultation and direct feedback from pharmacists via telephone regarding their asthma self-management and medication use. Pharmacists used a counseling framework that incorporates the Indian Health Services 3 Prime Questions and the RIM Technique (Recognition, Identification, and Management for managing medication use problems. Pharmacists encouraged patients to be active partners in the decision-making process to identify and address the underlying cause of medication use problems. Uniquely, this trial collected process and summative data using qualitative and quantitative approaches. Pharmacists’ training, the fidelity and quality of pharmacists’ service delivery, and short term patient outcomes are being evaluated. This evaluation will improve our ability to address research challenges and intervention barriers, refine staff training, explore patient perspectives, and evaluate measures’ power to provide preliminary patient outcome findings. Conclusion: A mixed method evaluation of a structured pharmacist intervention has the potential to offer insights regarding staff training, service fidelity and short term outcomes using quantitative and qualitative data in an RCT. Results will provide evidence regarding the feasibility and quality of carrying out the study and service delivery from the multiple

    Background To examine the trend of "mobile only" households, and households that have a mobile phone or landline telephone listed in the telephone directory, and to describe these groups by various socio-demographic and health indicators. Method Representative face-to-face population health surveys of South Australians, aged 15 years and over, were conducted in 1999, 2004, 2006, 2007 and 2008 (n = 14285, response rates = 51.9% to 70.6%). Self-reported information on mobile phone ownership and usage (1999 to 2008) and listings in White Pages telephone directory (2006 to 2008), and landline telephone connection and listings in the White Pages (1999 to 2008), was provided by participants. Additional information was collected on self-reported health conditions and health-related risk behaviours. Results Mobile only households have been steadily increasing from 1.4% in 1999 to 8.7% in 2008. In terms of sampling frame for telephone surveys, 68.7% of South Australian households in 2008 had at least a mobile phone or landline telephone listed in the White Pages (73.8% in 2006; 71.5% in 2007). The proportion of mobile only households was highest among young people, unemployed, people who were separated, divorced or never married, low income households, low SES areas, rural areas, current smokers, current asthma or people in the normal weight range. The proportion with landlines or mobiles telephone numbers listed in the White Pages telephone directory was highest among older people, married or in a defacto relationship or widowed, low SES areas, rural areas, people classified as overweight, or those diagnosed with arthritis or osteoporosis. Conclusion The rate of mobile only households has been increasing in Australia and is following worldwide trends, but has not reached the high levels seen internationally (12% to 52%). In general, the impact of mobile telephones on current sampling frames (exclusion or non-listing of mobile only households or not listed in the White

    Background Chronic diseases, like diabetes mellitus, heart disease and cancer are leading causes of death and disability. These conditions are at least partially preventable or modifiable, e.g. by enhancing patients’ self-management. We aimed to examine the effectiveness of telephone-based health coaching (TBHC) in chronically ill patients. Methods and Findings This prospective, pragmatic randomized controlled trial compares an intervention group (IG) of participants in TBHC to a control group (CG) without TBHC. Endpoints were assessed two years after enrolment. Three different groups of insurees with 1) multiple conditions (chronic campaign), 2) heart failure (heart failure campaign), or 3) chronic mental illness conditions (mental health campaign) were targeted. The telephone coaching included evidence-based information and was based on the concepts of motivational interviewing, shared decision-making, and collaborative goal setting. Patients received an average of 12.9 calls. Primary outcome was time from enrolment until hospital readmission within a two-year follow-up period. Secondary outcomes comprised the probability of hospital readmission, number of daily defined medication doses (DDD), frequency and duration of inability to work, and mortality within two years. All outcomes were collected from routine data provided by the statutory health insurance. As informed consent was obtained after randomization, propensity score matching (PSM) was used to minimize selection bias introduced by decliners. For the analysis of hospital readmission and mortality, we calculated Kaplan-Meier curves and estimated hazard ratios (HR). Probability of hospital readmission and probability of death were analysed by calculating odds ratios (OR). Quantity of health service use and inability to work were analysed by linear random effects regression models. PSM resulted in patient samples of 5,309 (IG: 2,713; CG: 2,596) in the chronic campaign, of 660 (IG: 338; CG: 322) in the

    The decline of cognitive function in old age is a great challenge for modern society. The simultaneous increase in dementia and other neurodegenerative diseases justifies a growing need for accurate and valid cognitive assessment instruments. Although in-person testing is considered the most effective and preferred administration mode of assessment, it can pose not only a research difficulty in reaching large and diverse population samples, but it may also limit the assessment and follow-up of individuals with either physical or health limitations or reduced motivation. Therefore, telephone-based cognitive screening instruments can be an alternative and attractive strategy to in-person assessments. In order to give a current view of the state of the art of telephone-based tools for cognitive assessment in aging, this review highlights some of the existing instruments with particular focus on data validation, cognitive domains assessed, administration time and instrument limitations and advantages. From the review of the literature, performed using the databases EBSCO, Science Direct and PubMed, it was possible to verify that while telephone-based tools are useful in research and clinical practice, providing a promising approach, the methodologies still need refinement in the validation steps, including comparison with either single instruments or neurocognitive test batteries, to improve specificity and sensitivity to validly detect subtle changes in cognition that may precede cognitive impairment.

    Full Text Available ABSTRACT Objective: to evaluate the effectiveness of the telephone intervention for promoting self-care related to physical activity and following a diet plan in users with diabetes, compared to conventional monitoring of users over a six-month period. Method: this was a randomized clinical trial, which included 210 users with diabetes, linked to eight Primary Health Units of Belo Horizonte, Minas Gerais. The experimental group (104 members received six telephone interventions over the six-month monitoring; the control group (106 members received conventional monitoring. To evaluate the self-care practices related to physical activity and following a healthy eating plan, in both groups, the self-care questionnaire was applied before the intervention and at three and six months after its start. Results: the mean effect of self-care scores in the experimental group was 1.03 to 1.78 higher than the control group, with progressive and significant improvement (p<0.001. Conclusion: the results indicate that the telephone intervention had a beneficial effect on diabetes self-care. The primary identifier of the clinical trials registry was: RBR-8wx7qb.

    Full Text Available Brain Computer Interface (BCI is a communication and control mechanism, which does not rely on any kind of muscular response to send a message to the external world. This technique is used to help the paralyzed people with spinal cord injury to have the ability to communicate with the external world. In this paper we emphasize to increase the BCI System bit rate for controlling a virtual telephone keypad. To achieve the proposed algorithm, a simulated virtual telephone keypad based on Steady State Visual Evoked Potential (SSVEP BCI system is developed. Dynamic programming technique with specifically modified Longest Common Subsequence (LCS algorithm is used. By comparing the paralyzed user selection with the recent, and then the rest, of the stored records in the file of the telephone, the user can save the rest of his choices for controlling the keypad and thence improving the overall performance of the BCI system. This axiomatic approach, which is used in searching the web pages for increasing the performance of the searching, is urgent to be used for the paralyzed people rather than the normal user.

    The major goal of diabetes control is to assist patients to perform self-care and metabolic control. One possible way to achieve this goal is education and regular monitoring of patients by telephone. Thus, the present study was conducted with the aim of investigating the impact of education and telephone follow-up on self-care and metabolic control in diabetic patients. This experimental study was conducted at a hospital in the Central Anatolia region of Turkey, with 88 diabetic patients including 44 intervention subjects and 44 control subjects. After an initial discussion, patients in the intervention group received education and telephone follow-up for 3 months. Required approvals were obtained before initiation of the study. Data were collected using a questionnaire form and the Diabetes Self-Care Scale. The Diabetes Self-Care Scale scores ranged between 140 and 210, where higher scores indicated increased self-care activities of patients. At the end of the study, the self-care score was found to increase from 61.3 ± 10.9 to 89.9 ± 12.3 in the intervention group (P self-care scores and had a positive impact on metabolic control variables. In light of these findings, we suggest that education and tele-health home monitoring may be provided on a continuous basis to help patients sustain self-care behaviors that they have adopted during the study period.

    Sexually transmitted human papillomaviruses (HPVs), most frequently HPV 16, are the primary cause of cervical carcinogenesis. The aim of this study was to evaluate the relationship between sexual behavior and prevalence and acquisition of HPV infection among British women attending regular cervical screening who responded to postal questionnaires and/or telephone interviews. A total of 1,880 women who had been tested for HPV in the ARTISTIC (A Randomized Trial In Screening To Improve Cytology) trial were randomized to three methods of data collection: group 1 (questionnaire including sexual history, no interview), group 2 (questionnaire excluding sexual history, short interview including sexual history), and group 3 (questionnaire and long interview including sexual history in both). Questions on sexual history included age at first sexual intercourse, sexually transmitted diseases, lifetime (total and regular) sexual partners, and number of partners in the last 5 years (total and new). Demographics, reproductive, cervical screening, and smoking history were also collected in questionnaires. The overall participation rate was 35%. There was good agreement (87.4-95.5%) on sexual behavior answers in questionnaires and interviews in women in group 3 and no significant differences between data obtained by questionnaire or interview. Odds ratios (OR) for both HPV prevalence and acquisition increased consistently with increasing numbers of lifetime sexual partners, regular partners, and new partners in the last 5 years (recent partners). No significant association was found for other characteristics investigated. The effect of recent sexual partners on HPV acquisition (OR for 2+ recent partners: 4.4, 95% CI: 1.7-11.2) was stronger than that of earlier (> 5 years ago) partners (OR for 2+ earlier partners: 2.2, 95% CI: 0.7-6.7) suggesting that most incident HPV infections are newly acquired rather than recurrent.

    OBJECTIVE To determine whether associations existed between onychectomy or onychectomy technique and house soiling in cats. DESIGN Cross-sectional study. SAMPLE 281 owners of 455 cats in Polk County, Iowa, identified via a list of randomly selected residential phone numbers of cat owners in that region. PROCEDURES A telephone survey was conducted to collect information from cat owners on factors hypothesized a priori to be associated with house soiling, including cat sex, reproductive status, medical history, and onychectomy history. When cats that had undergone onychectomy were identified, data were collected regarding the cat's age at the time of the procedure and whether a carbon dioxide laser (CDL) had been used. Information on history of house soiling behavior (urinating or defecating outside the litter box) was also collected. RESULTS Onychectomy technique was identified as a risk factor for house soiling. Cats for which a non-CDL technique was used had a higher risk of house soiling than cats for which the CDL technique was used. Cats that had undergone onychectomy and that lived in a multicat (3 to 5 cats) household were more than 3 times as likely to have house soiled as were single-housed cats with intact claws. CONCLUSIONS AND CLINICAL RELEVANCE Results of this cross-sectional study suggested that use of the CDL technique for onychectomy could decrease the risk of house soiling by cats relative to the risk associated with other techniques. This and other findings can be used to inform the decisions of owners and veterinarians when considering elective onychectomy for cats.

    Full Text Available Abstract Background African Americans with Type 2 diabetes (T2DM have higher prevalence of diabetes, poorer metabolic control, and greater risk for complications and death compared to American Whites. Poor outcomes in African Americans with T2DM can be attributed to patient, provider, and health systems level factors. Provider and health system factors account for Methods/Design We describe an ongoing four-year randomized clinical trial, using a 2 × 2 factorial design, which will test the efficacy of separate and combined telephone-delivered, diabetes knowledge/information and motivation/behavioral skills training interventions in high risk African Americans with poorly controlled T2DM (HbA1c ≥ 9%. Two-hundred thirty-two (232 male and female African-American participants, 18 years of age or older and with an HbA1c ≥ 9%, will be randomized into one of four groups for 12-weeks of phone interventions: (1 an education group, (2 a motivation/skills group, (3 a combined group or (4 a usual care/general health education group. Participants will be followed for 12-months to ascertain the effect of the interventions on glycemic control. Our primary hypothesis is that among African Americans with poorly controlled T2DM, patients randomized to the combined diabetes knowledge/information and motivation/behavioral skills training intervention will have significantly greater reduction in HbA1c at 12 months of follow-up compared to the usual care/general health education group. Discussion Results from this study will provide important insight into how best to deliver diabetes education and skills training in ethnic minorities and whether combined knowledge/information and motivation/behavioral skills training is superior to the usual method of delivering diabetes education for African Americans with poorly controlled T2DM.

  17. Combining telephone surveys and fishing catches self-report: the French sea bass recreational fishery assessment.

    Directory of Open Access Journals (Sweden)

    Delphine Rocklin

    Full Text Available Fisheries statistics are known to be underestimated, since they are mainly based on information about commercial fisheries. However, various types of fishing activities exist and evaluating them is necessary for implementing effective management plans. This paper assesses the characteristics and catches of the French European sea bass recreational fishery along the Atlantic coasts, through the combination of large-scale telephone surveys and fishing diaries study. Our results demonstrated that half of the total catches (mainly small fish were released at sea and that the mean length of a kept sea bass was 46.6 cm. We highlighted different patterns of fishing methods and type of gear used. Catches from boats were greater than from the shore, both in abundance and biomass, considering mean values per fishing trip as well as CPUE. Spearfishers caught the highest biomass of sea bass per fishing trip, but the fishing rod with lure was the most effective type of gear in terms of CPUE. Longlines had the highest CPUE value in abundance but not in biomass: they caught numerous but small sea bass. Handlines were less effective, catching few sea bass in both abundance and biomass. We estimated that the annual total recreational sea bass catches was 3,173 tonnes of which 2,345 tonnes were kept. Since the annual commercial catches landings were evaluated at 5,160 tonnes, recreational landings represent 30% of the total fishing catches on the Atlantic coasts of France. Using fishers' self-reports was a valuable way to obtain new information on data-poor fisheries. Our results underline the importance of evaluating recreational fishing as a part of the total amount of fisheries catches. More studies are critically needed to assess overall fish resources caught in order to develop effective fishery management tools.

    Full Text Available Abstract Background The demographics and lifestyles of Canadians are changing, thereby influencing food choices and food preparation in the home. Although different dietary practices are associated with increased risk of foodborne illness, our ability to evaluate food consumption trends and assess risks associated with foodborne illness is limited by lack of data on current eating habits and consumer food safety practices. The objective of this study was to describe, for the first time, the food consumption patterns in a Canadian-based population from a food safety perspective, in order to establish baseline data on actual food intake of individuals. Method A cross-sectional telephone survey of 2,332 randomly selected residents of Waterloo Region, Ontario, Canada (C-EnterNet pilot site was conducted between November 2005 and March 2006. Food intake was assessed using a 7-day dietary recall method. Results Certain food items were consumed more than others among the same food groups, and consumption of many food items varied by gender and age. Specific foods considered high-risk for the transmission of certain enteric pathogens were significantly more likely to be consumed by males (i.e. unpasteurized juice, bean sprouts, and undercooked meat and elderly individuals (i.e. undercooked eggs. The majority of households prepared and consumed most meals at home, allocating an average of 44 minutes to prepare a meal. Conclusion Baseline data on actual food intake is useful to public health professionals and food safety risk assessors for developing communication messages to consumers and in foodborne outbreak investigations.

    The cellular immune response to the human immunodeficiency virus, mediated by T lymphocytes, seems strong but fails to control the infection completely. In most virus infections, T cells either eliminate the virus or suppress it indefinitely as a harmless, persisting infection. But the human immunodeficiency virus undermines this control by infecting key immune cells, thereby impairing the response of both the infected CD4+ T cells and the uninfected CD8+ T cells. The failure of the latter to function efficiently facilitates the escape of virus from immune control and the collapse of the whole immune system.

    In the late 1960s, British mathematician John Conway invented a virtual mathematical machine that operates on a two-dimensional array of square cell. Each cell takes two states, live and dead. The cells' states are updated simultaneously and in discrete time. A dead cell comes to life if it has exactly three live neighbours. A live cell remains alive if two or three of its neighbours are alive, otherwise the cell dies. Conway's Game of Life became the most programmed solitary game and the most known cellular automaton.

    2009-05-01

    Cellular senescence is an effective anti-tumor barrier that acts by restraining the uncontrolled proliferation of cells carrying potentially oncogenic alterations. ING proteins are putative tumor suppressor proteins functionally linked to the p53 pathway and to chromatin regulation. ING proteins exert their tumor-protective action through different types of responses. Here, we review the evidence on the participation of ING proteins, mainly ING1 and ING2, in the implementation of the senescent response. The currently available data support an important role of ING proteins as regulators of senescence, in connection with the p53 pathway and chromatin organization.

    The majority of adults aged 18-34 years have only cellular phones, making random-digit dialing of landline telephones an obsolete methodology for surveillance of this population. However, 95% of this group has cellular phones. This article reports on the 2011 National Young Adult Health Survey (NYAHS), a pilot study conducted in the 50 US states and Washington, DC, that used random-digit dialing of cellular phones and benchmarked this methodology against that of the 2011 Behavioral Risk Factor Surveillance System (BRFSS). Comparisons of the demographic distributions of subjects in the NYAHS and BRFSS (aged 18-34 years) with US Census data revealed adequate reach for all demographic subgroups. After adjustment for design factors, the mean absolute deviations across demographic groups were 3 percentage points for the NYAHS and 2.8 percentage points for the BRFSS, nationally, and were comparable for each census region. Two-sided z tests comparing cigarette smoking prevalence revealed no significant differences between NYAHS and BRFSS participants overall or by subgroups. The design effects of the sampling weight were 2.09 for the NYAHS and 3.26 for the BRFSS. Response rates for the NYAHS and BRFSS cellular phone sampling frames were comparable. Our assessment of the NYAHS methodology found that random-digit dialing of cellular phones is a feasible methodology for surveillance of young adults.

    Full Text Available BACKGROUND: Mobile teledermatology has recently been shown to be suitable for teledermatology despite limitations in image definition in preliminary studies. The unique aspect of mobile teledermatology is that this system represents a filtering or triage system, allowing a sensitive approach for the management of patients with emergent skin diseases. METHODOLOGY/PRINCIPAL FINDINGS: In this study we investigated the feasibility of teleconsultation using a new generation of cellular phones in pigmented skin lesions. 18 patients were selected consecutively in the Pigmented Skin Lesions Clinic of the Department of Dermatology, Medical University of Graz, Graz (Austria. Clinical and dermoscopic images were acquired using a Sony Ericsson with a built-in two-megapixel camera. Two teleconsultants reviewed the images on a specific web application (http://www.dermahandy.net/default.asp where images had been uploaded in JPEG format. Compared to the face-to-face diagnoses, the two teleconsultants obtained a score of correct telediagnoses of 89% and of 91.5% reporting the clinical and dermoscopic images, respectively. CONCLUSIONS/SIGNIFICANCE: The present work is the first study performing mobile teledermoscopy using cellular phones. Mobile teledermatology has the potential to become an easy applicable tool for everyone and a new approach for enhanced self-monitoring for skin cancer screening in the spirit of the eHealth program of the European Commission Information for Society and Media.

  10. Cellular functions of the microprocessor.

    Science.gov (United States)

    Macias, Sara; Cordiner, Ross A; Cáceres, Javier F

    2013-08-01

    The microprocessor is a complex comprising the RNase III enzyme Drosha and the double-stranded RNA-binding protein DGCR8 (DiGeorge syndrome critical region 8 gene) that catalyses the nuclear step of miRNA (microRNA) biogenesis. DGCR8 recognizes the RNA substrate, whereas Drosha functions as an endonuclease. Recent global analyses of microprocessor and Dicer proteins have suggested novel functions for these components independent of their role in miRNA biogenesis. A HITS-CLIP (high-throughput sequencing of RNA isolated by cross-linking immunoprecipitation) experiment designed to identify novel substrates of the microprocessor revealed that this complex binds and regulates a large variety of cellular RNAs. The microprocessor-mediated cleavage of several classes of RNAs not only regulates transcript levels, but also modulates alternative splicing events, independently of miRNA function. Importantly, DGCR8 can also associate with other nucleases, suggesting the existence of alternative DGCR8 complexes that may regulate the fate of a subset of cellular RNAs. The aim of the present review is to provide an overview of the diverse functional roles of the microprocessor.

    Liu Quan-Xing; Jin Zhen

    2005-01-01

    In this paper the SEIRS epidemic spread is analysed, and a two-dimensional probability cellular automata model for SEIRS is presented. Each cellular automation cell represents a part of the population that may be found in one of five states of individuals: susceptible, exposed (or latency), infected, immunized (or recovered) and death. Here studied are the effects of two cases on the epidemic spread. i.e. the effects of non-segregation and segregation on the latency and the infected of population. The conclusion is reached that the epidemic will persist in the case of non-segregation but it will decrease in the case of segregation. The proposed model can serve as a basis for the development of algorithms to simulate real epidemics based on real data. Last we find the density series of the exposed and the infected will fluctuate near a positive equilibrium point, when the constant for the immunized is less than its corresponding constant τ0. Our theoretical results are verified by numerical simulations.

    Full Text Available Introduction: Out-of-hospital cardiac arrest (OHCA is a leading cause of death. The 2010 American Heart Association Emergency Cardiovascular Care (ECC Guidelines recognize emergency dispatch as an integral component of emergency medical service response to OHCA and call for all dispatchers to be trained to provide telephone cardiopulmonary resuscitation (T-CPR pre-arrival instructions. To begin to measure and improve this critical intervention, this study describes a nationwide survey of public safety answering points (PSAPs focusing on the current practices and resources available to provide T-CPR to callers with the overall goal of improving survival from OHCA. Methods: We conducted this survey in 2010, identifying 5,686 PSAPs; 3,555 had valid e-mail addresses and were contacted. Each received a preliminary e-mail announcing the survey, an e-mail with a link to the survey, and up to three follow-up e-mails for non-responders. The survey contained 23 primary questions with sub-questions depending on the response selected. Results: Of the 5,686 identified PSAPs in the United States, 3,555 (63% received the survey, with 1,924/3,555 (54% responding. Nearly all were public agencies (n=1,888, 98%. Eight hundred seventy-eight (46% responding agencies reported that they provide no instructions for medical emergencies, and 273 (14% reported that they are unable to transfer callers to another facility to provide T-CPR. Of the 1,924 respondents, 975 (51% reported that they provide pre-arrival instructions for OHCA: 67 (3% provide compression-only CPR instructions, 699 (36% reported traditional CPR instructions (chest compressions with rescue breathing, 166 (9% reported some other instructions incorporating ventilations and compressions, and 92 (5% did not specify the type of instructions provided. A validation follow up showed no substantial difference in the provision of instructions for OHCA by non-responders to the survey. Conclusion: This is the

    The health concerns have been raised following the enormous increase in the use of wireless mobile telephones throughout the world. This investigation had been taken, with the motive to find out whether mobile phone radiations cause any in vivo effects on the frequency of micronucleated exfoliated cells in the exposed subjects. A total of 109 subjects including 85 regular mobile phone users (exposed) and 24 non-users (controls) had participated in this study. Exfoliated cells were obtained by swabbing the buccal-mucosa from exposed as well as sex-age-matched controls. One thousand exfoliated cells were screened from each individual for nuclear anomalies including micronuclei (MN), karyolysis (KL), karyorrhexis (KH), broken egg (BE) and binucleated (BN) cells. The average daily duration of exposure to mobile phone radiations is 61.26 min with an overall average duration of exposure in term of years is 2.35 years in exposed subjects along with the 9.84+/-0.745 micronucleated cells (MNCs) and 10.72+/-0.889 total micronuclei (TMN) as compared to zero duration of exposure along with average 3.75+/-0.774 MNC and 4.00+/-0.808 TMN in controls. The means are significantly different in case of MNC and TMN at 0.01% level of significance. The mean of KL in controls is 13.17+/-2.750 and in exposed subjects is 13.06+/-1.793. The value of means of KH in exposed subjects (1.84+/-0.432) is slightly higher than in controls (1.42+/-0.737). Mean frequency of broken egg is found to be more in exposed subjects (0.65+/-0.276) as compared to controls (0.50+/-0.217). Frequency of presence of more than one nucleus in a cell (binucleated) is also higher in exposed (2.72+/-0.374) in comparison to controls (0.67+/-0.231). Although there is a slight increase in mean frequency of KH, BE and BN in exposed subjects but the difference is not found statistically significant. Correlation between 0-1, 1-2, 2-3 and 3-4 years of exposure and the frequency of MNC and TMN has been calculated and found to

  17. Does Telephone Audio Computer-Assisted Self-Interviewing Improve the Accuracy of Prevalence Estimates of Youth Smoking? Evidence from the UMass Tobacco Study.

    Despite their advantage for obtaining representative samples of adolescents, telephone surveys have been regarded as inferior for collecting data on youth tobacco use because they yield lower estimates than school-based self-administered surveys. Although no gold standard for smoking estimates exists, the lower estimates in telephone surveys have been attributed to underreporting due to youths' concern about parents or others overhearing their responses. Telephone audio computer-assisted self-interviewing (T-ACASI) is a cost-effective method for obtaining a representative sample of youths and provides increased privacy for the respondent. We hypothesized that using T-ACASI would encourage youths to more fully report smoking behavior compared to traditional interviewer-administered telephone methods. Our analysis further assessed whether respondent age, gender, race/ethnicity, and parental attitude toward smoking moderated the relationship between survey mode and smoking reports. Using data from a statewide tobacco use survey that randomly assigned youth respondents to either T-ACASI or interviewer-administered mode, we found youths were more likely to report smoking behaviors in T-ACASI mode and that this was especially true for girls, particularly those who believed their parents would disapprove strongly of their smoking. Findings suggest that traditional telephone surveys may underestimate smoking prevalence in most girls by a factor of two, and that a technique for insuring privacy for these respondents is an important component of effective telephone survey methodology.

  19. Discrete geodesics and cellular automata

    Arrighi, Pablo

    2015-01-01

    This paper proposes a dynamical notion of discrete geodesics, understood as straightest trajectories in discretized curved spacetime. The notion is generic, as it is formulated in terms of a general deviation function, but readily specializes to metric spaces such as discretized pseudo-riemannian manifolds. It is effective: an algorithm for computing these geodesics naturally follows, which allows numerical validation---as shown by computing the perihelion shift of a Mercury-like planet. It is consistent, in the continuum limit, with the standard notion of timelike geodesics in a pseudo-riemannian manifold. Whether the algorithm fits within the framework of cellular automata is discussed at length. KEYWORDS: Discrete connection, parallel transport, general relativity, Regge calculus.

    Seibert, H.; Scheffer, T.; Diebels, S.

    2016-09-01

    This contribution discusses an experimental possibility to characterise a cellular rubber in terms of the influence of multiaxiality, rate dependency under environmental temperature and its behaviour under hydrostatic pressure. In this context, a mixed open and closed cell rubber based on an ethylene propylene diene monomer is investigated exemplarily. The present article intends to give a general idea of the characterisation method and the considerable effects of this special type of material. The main focus lies on the experimental procedure and the used testing devices in combination with the analysis methods such as true three-dimensional digital image correlation. The structural compressibility is taken into account by an approach for a material model using the Theory of Porous Media with additional temperature dependence.

    2015-02-01

    Full Text Available Fungal secondary metabolism is often considered apart from the essential housekeeping functions of the cell. However, there are clear links between fundamental cellular metabolism and the biochemical pathways leading to secondary metabolite synthesis. Besides utilizing key biochemical precursors shared with the most essential processes of the cell (e.g. amino acids, acetyl CoA, NADPH, enzymes for secondary metabolite synthesis are compartmentalized at conserved subcellular sites that position pathway enzymes to use these common biochemical precursors. Co-compartmentalization of secondary metabolism pathway enzymes also may function to channel precursors, promote pathway efficiency and sequester pathway intermediates and products from the rest of the cell. In this review we discuss the compartmentalization of three well-studied fungal secondary metabolite biosynthetic pathways for penicillin G, aflatoxin and deoxynivalenol, and summarize evidence used to infer subcellular localization. We also discuss how these metabolites potentially are trafficked within the cell and may be exported.

  2. Fundamental Limits to Cellular Sensing

    2016-03-01

    In recent years experiments have demonstrated that living cells can measure low chemical concentrations with high precision, and much progress has been made in understanding what sets the fundamental limit to the precision of chemical sensing. Chemical concentration measurements start with the binding of ligand molecules to receptor proteins, which is an inherently noisy process, especially at low concentrations. The signaling networks that transmit the information on the ligand concentration from the receptors into the cell have to filter this receptor input noise as much as possible. These networks, however, are also intrinsically stochastic in nature, which means that they will also add noise to the transmitted signal. In this review, we will first discuss how the diffusive transport and binding of ligand to the receptor sets the receptor correlation time, which is the timescale over which fluctuations in the state of the receptor, arising from the stochastic receptor-ligand binding, decay. We then describe how downstream signaling pathways integrate these receptor-state fluctuations, and how the number of receptors, the receptor correlation time, and the effective integration time set by the downstream network, together impose a fundamental limit on the precision of sensing. We then discuss how cells can remove the receptor input noise while simultaneously suppressing the intrinsic noise in the signaling network. We describe why this mechanism of time integration requires three classes (groups) of resources—receptors and their integration time, readout molecules, energy—and how each resource class sets a fundamental sensing limit. We also briefly discuss the scheme of maximum-likelihood estimation, the role of receptor cooperativity, and how cellular copy protocols differ from canonical copy protocols typically considered in the computational literature, explaining why cellular sensing systems can never reach the Landauer limit on the optimal trade

    Accurate rainfall observations with high spatial and temporal resolutions are needed for hydrological applications, agriculture, meteorology, and climate monitoring. However, the majority of the land surface of the earth lacks accurate rainfall information and the number of rain gauges is even severely declining in Europe, South-America, and Africa. This calls for alternative sources of rainfall information. Various studies have shown that microwave links from operational cellular telecommunication networks may be employed for rainfall monitoring. Such networks cover 20% of the land surface of the earth and have a high density, especially in urban areas. The basic principle of rainfall monitoring using microwave links is as follows. Rainfall attenuates the electromagnetic signals transmitted from one telephone tower to another. By measuring the received power at one end of a microwave link as a function of time, the path-integrated attenuation due to rainfall can be calculated. Previous studies have shown that average rainfall intensities over the length of a link can be derived from the path-integrated attenuation. Here we show how one cellular telecommunication network can be used to retrieve the space-time dynamics of rainfall for an entire country. A dataset from a commercial microwave link network over the Netherlands is analyzed, containing data from an unprecedented number of links (2400) covering the land surface of the Netherlands (35500 km2). This dataset consists of 24 days with substantial rainfall in June - September 2011. A rainfall retrieval algorithm is presented to derive rainfall intensities from the microwave link data, which have a temporal resolution of 15 min. Rainfall maps (1 km spatial resolution) are generated from these rainfall intensities using Kriging. This algorithm is suited for real-time application, and is calibrated on a subset (12 days) of the dataset. The other 12 days in the dataset are used to validate the algorithm. Both

This study evaluated the effectiveness of a telephone-delivered psychoeducational intervention for family caregivers of PWD in alleviating caregiver burden and enhancing caregiving self-efficacy. Subjects and methods: In a single-blinded randomized controlled trial, 38 family caregivers of PWD were randomly allocated into an intervention group or a control group. The intervention group received psychoeducation from a registered social worker over the phone for 12 sessions. Caregivers in the control group were given a DVD containing educational information about dementia caregiving. Outcomes of the intervention were measured by the Chinese versions of the Zarit Burden Interview and the Revised Scale for Caregiving Self-efficacy. Mann–Whitney U tests were used to compare the differences between the intervention and control groups. Results: The level of burden of caregivers in the intervention group reduced significantly compared with caregivers in the control group. Caregivers in the intervention group also reported significantly more gain in self-efficacy in obtaining respite than the control group. Conclusion: A structured telephone intervention can benefit dementia caregivers in terms of self-efficacy and caregiving burden. The limitations of the research and recommendations for intervention are discussed. Keywords: telephone intervention, psychoeducation, dementia caregivers

    Full Text Available Abstract Background Nowadays, nurses play a central role in telephone triage in Dutch out-of-hours primary care. The percentage of calls that is handled through nurse telephone advice alone (NTAA appears to vary substantially between GP cooperatives. This study aims to explore which determinants are associated with NTAA and with subsequent return consultations to the GP. Methods For the ten most frequently presented problems, a two-week follow-up cohort study took place in one cooperative run by 25 GPs and 8 nurses, serving a population of 62,291 people. Random effects logistic regression analysis was used to study the determinants of NTAA and return consultation rates. The effect of NTAA on hospital referral rates was also studied as a proxy for severity of illness. Results The mean NTAA rate was 27.5% – ranging from 15.5% to 39.4% for the eight nurses. It was higher during the night (RR 1.63, CI 1.48–1.76 and lower with increasing age (RR 0.96, CI 0.93–0.99, per ten years or when the patient presented >2 problems (RR 0.65; CI 0.51–0.83. Using cough as reference category, NTAA was highest for earache (RR 1.49; CI 1.18–1.78 and lowest for chest pain (RR 0.18; CI 0.06–0.47. After correction for differences in case mix, significant variation in NTAA between nurses remained (p Conclusion Important inter-nurse variability may indicate differences in perception on tasks and/or differences in skill to handle telephone calls alone. Future research should focus more on modifiable determinants of NTAA rates.

  7. Intrinsic Simulations between Stochastic Cellular Automata

    2012-08-01

    Full Text Available The paper proposes a simple formalism for dealing with deterministic, non-deterministic and stochastic cellular automata in a unifying and composable manner. Armed with this formalism, we extend the notion of intrinsic simulation between deterministic cellular automata, to the non-deterministic and stochastic settings. We then provide explicit tools to prove or disprove the existence of such a simulation between two stochastic cellular automata, even though the intrinsic simulation relation is shown to be undecidable in dimension two and higher. The key result behind this is the caracterization of equality of stochastic global maps by the existence of a coupling between the random sources. We then prove that there is a universal non-deterministic cellular automaton, but no universal stochastic cellular automaton. Yet we provide stochastic cellular automata achieving optimal partial universality.

    2016-01-01

    Background Community-based services such as telephone support lines can provide valuable informational, emotional, and practical support for cancer patients via telephone- or Web-based (live chat or email) platforms. However, very little rigorous research has examined the efficacy of such services in improving patient outcomes. Objective This study will determine whether: proactive telephone or Web-delivered support produces outcomes superior to printed information; and Web-delivered support produces outcomes comparable to telephone support. Methods A consecutive sample of 501 lung cancer outpatients will be recruited from 50 Australian health services to participate in a patient-randomized controlled trial (RCT). Eligible individuals must: be 18 years or older; have received a lung cancer diagnosis (including mesothelioma) within the previous 4 months; have an approximate life expectancy of at least 6 months; and have Internet access. Participants will be randomly allocated to receive: (1) an information booklet, (2) proactive telephone support, or (3) proactive Web support, chat, and/or email. The primary patient outcomes will be measured by the General Health Questionnaire (GHQ-12) and Health Education and Impact Questionnaire (heiQ) at 3 and 6 months post recruitment. The acceptability of proactive recruitment strategies will also be assessed. Results It is hypothesized that participants receiving telephone or Web support will report reduced distress (GHQ-12 scores that are 0.3 standard deviations (SD) lower) and greater self-efficacy (heiQ scores that are 0.3 SDs higher) than participants receiving booklets. Individuals receiving Web support will report heiQ scores within 0.29 SDs of individuals receiving telephone support. Conclusions If proven effective, electronic approaches such as live-chat and email have the potential to increase the accessibility and continuity of supportive care delivered by community-based services.

    Barato, Andre C; Seifert, Udo

    2014-01-01

    We show that a rate of conditional Shannon entropy reduction, characterizing the learning of an internal process about an external process, is bounded by the thermodynamic entropy production. This approach allows for the definition of an informational efficiency that can be used to study cellular information processing. We analyze three models of increasing complexity inspired by the E. coli sensory network, where the external process is an external ligand concentration jumping between two values. We start with a simple model for which ATP must be consumed so that a protein inside the cell can learn about the external concentration. With a second model for a single receptor we show that the rate at which the receptor learns about the external environment can be nonzero even without any dissipation inside the cell since chemical work done by the external process compensates for this learning rate. The third model is more complete, also containing adaptation. For this model we show inter alia that a bacterium i...

    Understanding the origin of cellular life on Earth requires the discovery of plausible pathways for the transition from complex prebiotic chemistry to simple biology, defined as the emergence of chemical assemblies capable of Darwinian evolution. We have proposed that a simple primitive cell, or protocell, would consist of two key components: a protocell membrane that defines a spatially localized compartment, and an informational polymer that allows for the replication and inheritance of functional information. Recent studies of vesicles composed of fatty-acid membranes have shed considerable light on pathways for protocell growth and division, as well as means by which protocells could take up nutrients from their environment. Additional work with genetic polymers has provided insight into the potential for chemical genome replication and compatibility with membrane encapsulation. The integration of a dynamic fatty-acid compartment with robust, generalized genetic polymer replication would yield a laboratory model of a protocell with the potential for classical Darwinian biological evolution, and may help to evaluate potential pathways for the emergence of life on the early Earth. Here we discuss efforts to devise such an integrated protocell model.

    Aluminium is a serious environmental toxicant and is inimical to biota. Omnipresent, it is linked with a number of disorders in man including Alzheimer's disease, Parkinson's dementia and osteomalacia. Evidence supporting aluminium as an aetiological agent in such disorders is not conclusive and suffers principally from a lack of consensus with respect to aluminium's toxic mode of action. Obligatory to the elucidation of toxic mechanisms is an understanding of the biological availability of aluminium. This describes the fate of and response to aluminium in any biological system and is thus an important influence of the toxicity of aluminium. A general theme in much aluminium toxicity is an accelerated cell death. Herein mechanisms are described to account for cell death from both acute and chronic aluminium challenges. Aluminium associations with both extracellular surfaces and intracellular ligands are implicated. The cellular response to aluminium is found to be biphasic having both stimulatory and inhibitory components. In either case the disruption of second messenger systems is observed and GTPase cycles are potential target sites. Specific ligands for aluminium at these sites are unknown though are likely to be proteins upon which oxygen-based functional groups are orientated to give exceptionally strong binding with the free aluminium ion.

    Full Text Available Abstract Background Using a different mode of contact on the final follow-up to survey non-respondents is an identified strategy to increase response rates. This study was designed to determine if a reminder phone call or a phone interview as a final mode of contact to a mailed survey works better to increase response rates and which strategy is more cost effective. Methods A randomized study was embedded within a survey study of individuals treated with ulcerative colitis conducted in March 2009 in Olmsted County, Minnesota. After two mail contacts, non-respondents were randomly assigned to either a reminder telephone call or a telephone interview. Average cost per completed interview and response rates were compared between the two experimental conditions. Results The response rate in the reminder group and the interview did not differ where we considered both a completed survey and a signed form a complete (24% vs. 29%, p = 0.08. However, if such a signed form was not required, there was a substantial advantage to completing the interview over the phone (24% vs. 43%, p Conclusions The additional cost of completing an interview is worth it when an additional signed form is not required of the respondent. However, when such a signed form is required, offering an interview instead of a reminder phone call as a follow up to non-respondents does not increase response rates enough to outweigh the additional costs.

    This study examined the efficacy of motivational interviewing (MI) for increasing physical activity in aging adults. Eighty-six participants aged 55 years and older were randomly assigned to receive either four weekly sessions of telephone-based MI for increasing physical activity, or a healthy activity living guide (information only control). Changes from baseline weekly caloric expenditure from physical activity, self-efficacy for physical activity, and stage of change for physical activity were compared across groups at posttreatment and six months follow-up. Results indicated that MI participants had higher weekly caloric expenditures from physical activity at posttreatment, but not at six months follow-up; higher self-efficacy for physical activity at six months follow-up; and demonstrated greater stage of change progression across assessments. These findings support the use of telephone-based MI for increasing physical activity in older adults in the short-term. Future studies will need to determine if follow-up booster sessions increase long-term efficacy.

    Full Text Available Environmental signals induce diverse cellular differentiation programs. In certain systems, cells defer differentiation for extended time periods after the signal appears, proliferating through multiple rounds of cell division before committing to a new fate. How can cells set a deferral time much longer than the cell cycle? Here we study Bacillus subtilis cells that respond to sudden nutrient limitation with multiple rounds of growth and division before differentiating into spores. A well-characterized genetic circuit controls the concentration and phosphorylation of the master regulator Spo0A, which rises to a critical concentration to initiate sporulation. However, it remains unclear how this circuit enables cells to defer sporulation for multiple cell cycles. Using quantitative time-lapse fluorescence microscopy of Spo0A dynamics in individual cells, we observed pulses of Spo0A phosphorylation at a characteristic cell cycle phase. Pulse amplitudes grew systematically and cell-autonomously over multiple cell cycles leading up to sporulation. This pulse growth required a key positive feedback loop involving the sporulation kinases, without which the deferral of sporulation became ultrasensitive to kinase expression. Thus, deferral is controlled by a pulsed positive feedback loop in which kinase expression is activated by pulses of Spo0A phosphorylation. This pulsed positive feedback architecture provides a more robust mechanism for setting deferral times than constitutive kinase expression. Finally, using mathematical modeling, we show how pulsing and time delays together enable "polyphasic" positive feedback, in which different parts of a feedback loop are active at different times. Polyphasic feedback can enable more accurate tuning of long deferral times. Together, these results suggest that Bacillus subtilis uses a pulsed positive feedback loop to implement a "timer" that operates over timescales much longer than a cell cycle.

    Cellular systems are observed everywhere in nature, from crystal domains in metals, soap froth and cucumber cells to the network of cosmological voids. Surprisingly, despite their disparate scale and origin all cellular systems follow certain scaling laws relating their geometry, topology and dynamics. Using a cosmological N-body simulation we found that the Cosmic Web, the largest known cellular system, follows the same scaling relations seen elsewhere in nature. Our results extend the validity of scaling relations in cellular systems by over 30 orders of magnitude in scale with respect to previous studies. The dynamics of cellular systems can be used to interpret local observations such as the local velocity anomaly as the result of a collapsing void in our cosmic backyard. Moreover, scaling relations depend on the curvature of space, providing an independent measure of geometry.

    Advances in the study of hematopoietic cell maturation have paved the way to a deeper understanding the stem and progenitor cellular hierarchy in the mammary gland. The mammary epithelium, unlike the hematopoietic cellular hierarchy, sits in a complex niche where communication between epithelial cells and signals from the systemic hormonal milieu, as well as from extra-cellular matrix, influence cell fate decisions and contribute to tissue homeostasis. We review the discovery, definition and regulation of the mammary cellular hierarchy and we describe the development of the concepts that have guided our investigations. We outline recent advances in in vivo lineage tracing that is now challenging many of our assumptions regarding the behavior of mammary stem cells, and we show how understanding these cellular lineages has altered our view of breast cancer.

    A physician/nurse collaborative team sought to determine whether a nurse-led telephone clinic (Teleclinic) could effectively and safely be used to follow patients with indolent and chronic hematological malignancies. Patients seen at their routine follow-up visit were assessed for eligibility for the Teleclinic, then referred to the pilot Teleclinic by their oncologist. Patients were interviewed by telephone by an oncology nurse experienced in hematologic malignancies. Fifty-three patients consented to participate in the pilot study. Following their Teleclinic interview, patients were asked to complete a "Subject Satisfaction Questionnaire" (SSQ). Overall patient satisfaction with the Teleclinic was high. It was determined that patients with low-grade and chronic hematological malignancies could be followed effectively and safely by an oncology nurse-led telephone clinic.

Applications of lean practices to health care are found worldwide. Despite that, new contributions are required because the application of lean thinking to hospitals has a long way to go. Lean practices and thinking do not include, in the literature or practice programs, any references to triage systems in health care units. The common triage systems require physical presence, but there are alternative methods to avoid the need to move patients: these alternative triage systems, given their characteristics, may be included in the spectrum of lean practices. Currently, patients that are already known to suffer from cancer are encouraged to go to hospital (public or private, with an oncological focus when facing side effects from chemotherapy or radiation treatments; they are then submitted to a triage system (present themselves to the hospital for examination. The authors of this paper propose the introduction of telephone or email triage for impaired patients as a valid substitute for moving them physically, thereby often avoiding several unnecessary moves. This approach has, in fact, characteristics similar to a lean practice in that it reduces costs and maintains, if done properly, the overall service offered. The proposed 'remote' triage emerged from the results of a large survey sent to patients and also as the outcome of a set of semistructured interviews conducted with hospital nurses. With the results they obtained, the authors felt comfortable proposing this approach both to public and private hospitals, because the study was conducted in the most important, largest, and best-known oncological unit in Spain. As a final result, the health care unit studied is now taking

    Full Text Available Abstract Background The aims of the current study were: a to quantitatively compare data obtained by Short Message Service (SMS with data from a telephone interview, b to investigate whether the respondents had found it acceptable to answer the weekly two SMS questions, c to explore whether an additional weekly third SMS question would have been acceptable, and d to calculate the total cost of using the SMS technology. Methods SMS technology was used each week for 53 weeks to monitor 260 patients with low back pain (LBP in a clinical study. Each week, these patients were asked the same two questions: "How many days in the past week have you had problems due to LBP?" and "How many days in the past week have you been off work due to LBP problems?" The last 31 patients were also contacted by telephone 53 weeks after recruitment and asked to recall the number of days with LBP problems and days off work for the a past week, b past month, and c past year. The two sets of answers to the same questions for these patients were compared. Patients were also asked whether a third SMS question would have been acceptable. The test-retest reliability was compared for 1-week, 1-month, and 1-year. Bland-Altman limits of agreement were calculated. The two quantitative questions were reported as percentages. Actual costs for the SMS-Track-Questionnaire (SMS-T-Q were compared with estimated costs for paper version surveys. Results There was high agreement between telephone interview and SMS-T-Q responses for the 1-week and 1-month recall. In contrast, the 1-year recall showed very low agreement. A third SMS question would have been acceptable. The SMS system was considerably less costly than a paper-based survey, beyond a certain threshold number of questionnaires. Conclusion SMS-T-Q appears to be a cheaper and better method to collect reliable LBP data than paper-based surveys.

    Full Text Available Abstract Background A large proportion of adults fail to meet public health guidelines for physical activity as well as fruit, vegetable and fat intake. Interventions are needed to improve these health behaviors. Both computer tailoring and motivational interviewing have shown themselves to be promising techniques for health behavior change. The Vitalum project aims to compare the efficacy of these techniques in improving the health behaviors of adults aged 45–70. This paper describes the design of the Vitalum study. Methods/Design Dutch general medical practices (N = 23 were recruited via a registration network or by personal invitation. The participants were then enrolled through these general practices using an invitational letter. They (n = 2,881 received a written baseline questionnaire to assess health behaviors, and potential psychosocial and socio-demographic behavioral determinants. A power analysis indicated that 1,600 participants who were failing to meet the guidelines for physical activity and either fruit or vegetable consumption were needed. Eligible participants were stratified based on hypertension status and randomized into one of four intervention groups: tailored print communication, telephone motivational interviewing, combined, and control. The first two groups either received four letters or took part in four interviews, whereas the combined group received two letters and took part in two interviews in turns at 5, 13, 30 and 43 weeks after returning the baseline questionnaire. Each letter and interview focused on physical activity or nutrition behavior. The participants also took part in a telephone survey 25 weeks after baseline to gather new information for tailoring. There were two follow-up questionnaires, at 47 and 73 weeks after baseline, to measure short- and long-term effects. The control group received a tailored letter after the last posttest.

    The cellular senescence definition comes to the fact of cells irreversible proliferation disability. Besides the cell cycle arrest, senescent cells go through some morphological, biochemical, and functional changes which are the signs of cellular senescence. The senescent cells (including replicative senescence and stress-induced premature senescence) of all the tissues look alike. They are metabolically active and possess the set of characteristics in vitro and in vivo, which are known as biomarkers of aging and cellular senescence. Among biomarkers of cellular senescence telomere shortening is a rather elegant frequently used biomarker. Validity of telomere shortening as a marker for cellular senescence is based on theoretical and experimental data.

    Full Text Available Abstract Background Telephone hotlines designed to address common concerns in the early postpartum could be a useful resource for parents. Our aim was to test the feasibility of using a telephone as an intervention in a randomized controlled trial. We also aimed to test to use of algorithms to address parental concerns through a telephone hotline. Methods Healthy first-time mothers were recruited from postpartum wards of hospitals throughout Lebanon. Participants were given the number of a 24-hour telephone hotline that they could access for the first four months after delivery. Calls were answered by a midwife using algorithms developed by the study team whenever possible. Callers with medical complaints were referred to their physicians. Call patterns and content were recorded and analyzed. Results Eighty-four of the 353 women enrolled (24% used the hotline. Sixty percent of the women who used the service called more than once, and all callers reported they were satisfied with the service. The midwife received an average of three calls per day and most calls occurred during the first four weeks postpartum. Our algorithms were used to answer questions in 62.8% of calls and 18.6% of calls required referral to a physician. Of the questions related to mothers, 66% were about breastfeeding. Sixty percent of questions related to the infant were about routine care and 23% were about excessive crying. Conclusions Utilization of a telephone hotline service for postpartum support is highest in the first four weeks postpartum. Most questions are related to breastfeeding, routine newborn care, and management of a fussy infant. It is feasible to test a telephone hotline as an intervention in a randomized controlled trial. Algorithms can be developed to provide standardized answers to the most common questions.

    1999-01-01

    Full Text Available Cellular interactions involve many types of cell surface molecules and operate via homophilic and/or heterophilic protein-protein and protein-carbohydrate binding. Our investigations in different model-systems (marine invertebrates and mammals have provided direct evidence that a novel class of primordial proteoglycans, named by us gliconectins, can mediate cell adhesion via a new alternative molecular mechanism of polyvalent carbohydrate-carbohydrate binding. Biochemical characterization of isolated and purified glyconectins revealed the presence of specific carbohydrate structures, acidic glycans, different from classical glycosaminoglycans. Such acidic glycans of high molecular weight containing fucose, glucuronic or galacturonic acids, and sulfate groups, originally found in sponges and sea urchin embryos, may represent a new class of carbohydrate carcino-embryonal antigens in mice and humans. Such interactions between biological macromolecules are usually investigated by kinetic binding studies, calorimetric methods, X-ray diffraction, nuclear magnetic resonance, and other spectroscopic analyses. However, these methods do not supply a direct estimation of the intermolecular binding forces that are fundamental for the function of the ligand-receptor association. Recently, we have introduced atomic force microscopy to quantify the binding strength between cell adhesion proteoglycans. Measurement of binding forces intrinsic to cell adhesion proteoglycans is necessary to assess their contribution to the maintenance of the anatomical integrity of multicellular organisms. As a model, we selected the glyconectin 1, a cell adhesion proteoglycan isolated from the marine sponge Microciona prolifera. This glyconectin mediates in vivo cell recognition and aggregation via homophilic, species-specific, polyvalent, and calcium ion-dependent carbohydrate-carbohydrate interactions. Under physiological conditions, an adhesive force of up to 400 piconewtons

    2008-01-01

    Cellular cell pattern evolution of cylindrically-diverging detonations is numerically simulated successfully by solving two-dimensional Euler equations implemented with an improved two-step chemical kinetic model. From the simulation, three cell bifurcation modes are observed during the evolution and referred to as concave front focusing, kinked and wrinkled wave front instability, and self-merging of cellular cells. Numerical research demonstrates that the wave front expansion resulted from detonation front diverging plays a major role in the cellular cell bifurcation, which can disturb the nonlinearly self-sustained mechanism of detonations and finally lead to cell bifurcations.

    Full Text Available Abstract The variety of foreign bodies inserted into or externally attached to the genitourinary tract defies imagination and includes all types of objects. The frequency of such cases renders these an important addition to the diseases of the genitourinary organs. The most common motive associated with the insertion of foreign bodies into the genitourinary tract is sexual or erotic in nature. In adults this is commonly caused by the insertion of objects used for masturbation and is frequently associated with mental health disorders. We report a case of insertion of telephone cable wire into the urethra. Our case highlights the importance of good history, clinical examination, relevant radiological investigation and simple measures to solve the problem.

  7. Responses to language barriers in consultations with refugees and asylum seekers: a telephone survey of Irish general practitioners.

    LENUS (Irish Health Repository)

    MacFarlane, Anne

    2008-01-01

    BACKGROUND: Refugees and asylum seekers experience language barriers in general practice. Qualitative studies have found that responses to language barriers in general practice are ad hoc with use of both professional interpreters and informal interpreters (patients\\' relatives or friends). However, the scale of the issues involved is unknown. This study quantifies the need for language assistance in general practice consultations and examines the experience of, and satisfaction with, methods of language assistance utilized. METHODS: Data were collected by telephone survey with general practitioners in a regional health authority in Ireland between July-August 2004. Each respondent was asked a series of questions about consulting with refugees and asylum seekers, the need for language assistance and the kind of language assistance used. RESULTS: There was a 70% (n = 56\\/80) response rate to the telephone survey. The majority of respondents (77%) said that they had experienced consultations with refugees and asylum seekers in which language assistance was required. Despite this, general practitioners in the majority of cases managed without an interpreter or used informal methods of interpretation. In fact, when given a choice general practitioners would more often choose informal over professional methods of interpretation despite the fact that confidentiality was a significant concern. CONCLUSION: The need for language assistance in consultations with refugees and asylum seekers in Irish general practice is high. General practitioners rely on informal responses. It is necessary to improve knowledge about the organisational contexts that shape general practitioners responses. We also recommend dialogue between general practitioners, patients and interpreters about the relative merits of informal and professional methods of interpretation so that general practitioners\\' choices are responsive to the needs of patients with limited English.

The authors of this paper propose the introduction of telephone or email triage for impaired patients as a valid substitute for moving them physically, thereby often avoiding several unnecessary moves. This approach has, in fact, characteristics similar to a lean practice in that it reduces costs and maintains, if done properly, the overall service offered. The proposed 'remote' triage emerged from the results of a large survey sent to patients and also as the outcome of a set of semistructured interviews conducted with hospital nurses. With the results they obtained, the authors felt comfortable proposing this approach both to public and private hospitals, because the study was conducted in the most important, largest, and best-known oncological unit in Spain. As a final result, the health care unit studied is now taking the first steps to implement a remote triage system by telephone, and has begun to reduce the previously necessary movement of impaired patients.

    Full Text Available Abstract Background The negative consequences of acute otitis media (AOM on the quality of life (QOL of children and their families need to be measured to assess benefits of preventive interventions. Methods A new questionnaire was specifically designed for use in telephone surveys. A random sample of Canadian families was selected using random-digit dialling. Caregivers of children 6-59 months of age who experienced at least one AOM episode during the last 12 months were interviewed. Multidimensional severity and global QOL scores were measured both for affected children and their caregivers. Internal consistency of scores was assessed using standard tests. Results Of the 502 eligible caregivers who completed the survey, 161 (32% reported at least one AOM episode during the last 12 months and these cases were included in the analysis. Average severity was 2.6 for children and 2.4 for caregivers on a 1 to 4 scale (maximum severity. Cronbach alpha values were 0.78 and 0.81 for the severity score of children and caregivers respectively. Average QOL was 3.4 for children and 3.5 for caregivers on a 1 to 5 scale (best QOL. There was moderate to high correlation between severity and QOL scores, and between these scores and duration of AOM episodes. Conclusions The questionnaire was easy to use during telephone interviews and results suggest good reliability and validity of the different scores to measure AOM severity and QOL of children and their caregivers during an AOM episode.

    Full Text Available Abstract Background Refugees and asylum seekers experience language barriers in general practice. Qualitative studies have found that responses to language barriers in general practice are ad hoc with use of both professional interpreters and informal interpreters (patients' relatives or friends. However, the scale of the issues involved is unknown. This study quantifies the need for language assistance in general practice consultations and examines the experience of, and satisfaction with, methods of language assistance utilized. Methods Data were collected by telephone survey with general practitioners in a regional health authority in Ireland between July-August 2004. Each respondent was asked a series of questions about consulting with refugees and asylum seekers, the need for language assistance and the kind of language assistance used. Results There was a 70% (n = 56/80 response rate to the telephone survey. The majority of respondents (77% said that they had experienced consultations with refugees and asylum seekers in which language assistance was required. Despite this, general practitioners in the majority of cases managed without an interpreter or used informal methods of interpretation. In fact, when given a choice general practitioners would more often choose informal over professional methods of interpretation despite the fact that confidentiality was a significant concern. Conclusion The need for language assistance in consultations with refugees and asylum seekers in Irish general practice is high. General practitioners rely on informal responses. It is necessary to improve knowledge about the organisational contexts that shape general practitioners responses. We also recommend dialogue between general practitioners, patients and interpreters about the relative merits of informal and professional methods of interpretation so that general practitioners' choices are responsive to the needs of patients with limited English.

    Full Text Available Background: The purpose of this study was to evaluate the advantages of a telephone consultation with a specialist in paediatric surgery after taking photographs and video images by a general practitioner for the diagnosis of some diseases. Materials and Methods: This was a prospective study of the reliability of paediatric surgery online consultation among specialists and general practitioners. Results: Of 26 general practitioners included in the study, 12 were working in the city and 14 were working in districts outside the city. A total of 41 pictures and 3 videos of 38 patients were sent and evaluated together with the medical history and clinical findings. These patients were diagnosed with umbilical granuloma (n = 6, physiological/pathological phimosis (n = 6, balanitis (n = 6, hydrocele (n = 6, umbilical hernia (n = 4, smegma cyst (n = 2, reductable inguinal hernia (n = 1, incarcerated inguinal hernia (n = 1, paraphimosis (n = 1, burried penis (n = 1, hypospadias (n = 1, epigastric hernia (n = 1, vulva synechia (n = 1, and rectal prolapse (n = 1. Twelve patients were asked to be referred urgently, but it was suggested that only two of these patients, who had paraphimosis and incarcerated inguinal hernia be referred in emergency conditions. It was decided that there was no need for the other ten patients to be referred to a specialist at night or at the weekend. All diagnoses were confirmed to be true, when all patients underwent examination in the pediatric surgery clinic in elective conditions. Conclusion: Evaluation of photographs and video images of a lesion together with medical history and clinical findings via a telephone consultation between a paediatric surgery specialist and a general practitioner provides a definitive diagnosis and prevents patients from being referred unnecessarily.

    Full Text Available The prevalence of diabetes is increasing worldwide. The objective of this study is to estimate the prevalence of self-reported diabetes in Brazilian adults and to describe its population correlates as well as the clinical characteristics of the reported cases.We analyzed basic and supplementary data of 54.144 subjects participating in VIGITEL 2011 (Surveillance System for Risk and Protective Factors for Chronic Diseases, a telephone survey based on a probabilistic sample of subjects ≥ 18 years old residing in Brazilian state capitals and the Federal District. Estimates reported are weighted so as to represent the surveyed population.The prevalence of self-reported diabetes was 6.3% (95% CI 5.9-6.7, increasing markedly with age and nutritional status, and decreasing with level of education. Prevalence was higher among those self-declaring their race/color as black. Most cases (90% reported the diagnosis being made at 35 years or older. The vast majority (99.8% of self-reported cases informed having previously performed at least one glucose test, and 76% of those not reporting diabetes also informed having previously performed glucose testing. Most cases (92.6% reported following some form of diabetes treatment, 79% taking medication.The estimated prevalence of known diabetes found, 6.3%, is consistent with estimates given by international summaries. The additional data collected in VIGITEL 2011 regarding previous glucose testing and current treatment support the use of telephone-based information to monitor the prevalence of known diabetes in Brazilian capitals.

    Full Text Available Abstract Background Households with fixed-line telephones have decreased while mobile (cell phone ownership has increased. We therefore sought to examine the feasibility of recruiting young women for a national health survey through random digit dialling mobile phones. Methods Two samples of women aged 18 to 39 years were surveyed by random digit dialling fixed and mobile numbers. We compared participation rates and responses to a questionnaire between women surveyed by each contact method. Results After dialling 5,390 fixed-lines and 3,697 mobile numbers, 140 and 128 women were recruited respectively. Among women contacted and found to be eligible, participation rates were 74% for fixed-lines and 88% for mobiles. Taking into account calls to numbers where eligibility was unknown (e.g. unanswered calls the estimated response rates were 54% and 45% respectively. Of women contacted by fixed-line, 97% reported having a mobile while 61% of those contacted by mobile reported having a fixed-line at home. After adjusting for age, there were no significant differences between mobile-only and fixed-line responders with respect to education, residence, and various health behaviours; however compared to those with fixed-lines, mobile-only women were more likely to identify as Indigenous (OR 4.99, 95%CI 1.52-16.34 and less likely to live at home with their parents (OR 0.09, 95%CI 0.03-0.29. Conclusions Random digit dialling mobile phones to conduct a health survey in young Australian women is feasible, gives a comparable response rate and a more representative sample than dialling fixed-lines only. Telephone surveys of young women should include mobile dialling.

    Objective Many adolescents with obsessive-compulsive disorder (OCD) do not have access to evidence-based treatment. A randomized controlled non-inferiority trial was conducted in a specialist OCD clinic to evaluate the effectiveness of telephone cognitive-behavioral therapy (TCBT) for adolescents with OCD compared to standard clinic-based, face-to-face CBT. Method Seventy-two adolescents, aged 11 through 18 years with primary OCD, and their parents were randomized to receive specialist TCBT or CBT. The intervention provided differed only in the method of treatment delivery. All participants received up to 14 sessions of CBT, incorporating exposure with response prevention (E/RP), provided by experienced therapists. The primary outcome measure was the Children’s Yale–Brown Obsessive-Compulsive Scale (CY-BOCS). Blind assessor ratings were obtained at midtreatment, posttreatment, 3-month, 6-month, and 12-month follow-up. Results Intent-to-treat analyses indicated that TCBT was not inferior to face-to-face CBT at posttreatment, 3-month, and 6-month follow-up. At 12-month follow-up, there were no significant between-group differences on the CY-BOCS, but the confidence intervals exceeded the non-inferiority threshold. All secondary measures confirmed non-inferiority at all assessment points. Improvements made during treatment were maintained through to 12-month follow-up. Participants in each condition reported high levels of satisfaction with the intervention received. Conclusion TCBT is an effective treatment and is not inferior to standard clinic-based CBT, at least in the midterm. This approach provides a means of making a specialized treatment more accessible to many adolescents with OCD.

    Growing demand for and limited geographic access to genetic counseling services is increasing the need for alternative service delivery models (SDM) like telephone genetic counseling (TGC). Little research has been done on genetic counselors' perspectives of the practice of TGC. We created an anonymous online survey to assess whether telephone genetic counselors believed the tasks identified in the ABGC (American Board of Genetic Counseling) Practice Analysis were performed similarly or differently in TGC compared to in person genetic counseling (IPGC). If there were differences noted, we sought to determine the nature of the differences and if additional training might be needed to address them. Eighty eight genetic counselors with experience in TGC completed some or all of the survey. Respondents identified differences in 13 (14.8%) of the 88 tasks studied. The tasks identified as most different in TGC were: "establishing rapport through verbal and nonverbal interactions" (60.2%; 50/83 respondents identified the task as different), "recognizing factors affecting the counseling interaction" (47.8%; 32/67), "assessing client/family emotions, support, etc." (40.1%; 27/66) and "educating clients about basic genetic concepts" (35.6%; 26/73). A slight majority (53.8%; 35/65) felt additional training was needed to communicate information without visual aids and more effectively perform psychosocial assessments. In summary, although a majority of genetic counseling tasks are performed similarly between TGC and IPGC, TGC counselors recognize that specific training in the TGC model may be needed to address the key differences.
