  1. Telephone operator change: your questions answered

    CERN Multimedia

    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...

  2. Cellular telephone use among primary school children in Germany

    International Nuclear Information System (INIS)

    Background: There is some concern about potential health risks of cellular telephone use to children. We assessed data on how many children own a cellular telephone and on how often they use it in a population-based sample. Methods: We carried out a cross-sectional study among children in their fourth elementary school year, with a median-age of 10 years. The study was carried out in Mainz (Germany), a city with about 200,000 inhabitants. The study base comprised all 37 primary schools in Mainz and near surroundings. Altogether, 1933 children from 34 primary schools took part in the survey (participation rate of 87.8%). Results: Roughly a third of all children (n = 671, 34.7%) reported to own a cellular telephone. Overall, 119 (6.2%) children used a cellular telephone for making calls at least once a day, 123 (6.4%) used it several times a week and 876 (45.3%) children used it only once in a while. The remaining 805 (41.6%) children had never used a cellular telephone. The probability of owning a cellular telephone among children was associated with older age, being male, having no siblings, giving full particulars to height and weight, more time spent watching TV and playing computer games, being picked up by their parents from school by car (instead of walking or cycling) and going to bed late. The proportion of cellular telephone owners was somewhat higher in classes with more children from socially disadvantaged families. Conclusions: Our study shows that both ownership of a cellular telephone as well as the regular use of it are already quite frequent among children in the fourth grade of primary school. With regard to potential long-term effects, we recommend follow-up studies with children

    Craig, William W.; Labov, Simon E.

    2011-06-14

    A network of radiation detection instruments, each having a small solid state radiation sensor module integrated into a cellular phone for providing radiation detection data and analysis directly to a user. The sensor module includes a solid-state crystal bonded to an ASIC readout providing a low cost, low power, light weight compact instrument to detect and measure radiation energies in the local ambient radiation field. In particular, the photon energy, time of event, and location of the detection instrument at the time of detection is recorded for real time transmission to a central data collection/analysis system. The collected data from the entire network of radiation detection instruments are combined by intelligent correlation/analysis algorithms which map the background radiation and detect, identify and track radiation anomalies in the region.

  4. Streamflow gaging in a remote area using cellular telephone telemetry

    International Nuclear Information System (INIS)

    In this paper a case study is presented describing the utilization of cellular phone technology in a remote sensing situation. Because expected annual energy estimates are vital in planning small hydroelectric projects, it is important that the flow data from river gaging stations provide reliable information to the engineer. When the project is situated in a remote area where gaging stations are unavailable. such as on an island or in emerging nations, the design engineer may need to provide the flow data himself. The problem of transmitting the flow data from a remote mountain stream away from any roads and telephone lines, to the office for computer analysis was solved by using an innovative method utilizing cellular telephones to access raw data from solar powered data loggers and pressure transducer gaging instruments

    Full Text Available This paper examines interviewer-respondent interaction in the collection of demographic data. Conversation analysis (CA makes transparent the interaction between an interviewer and 25 respondents on a question about pregnancy and birth timing in an Australian telephone survey, Negotiating the Life Course. The analysis focuses on the troubles that occur and the work interviewers do to fit respondents' answers to the survey researcher's categories. Interviewers are shown to act as mediators in difficult interaction, with responses often distorted by question format, the imperative of achieving an allowed response, and the need to keep the respondent in the survey.

    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.

  8. Epidemiological Safety Surveillance of Cellular Telephones in the US (invited paper)

    International Nuclear Information System (INIS)

    In 1994 a surveillance programme was initiated to monitor the effects of exposure to the human head from radiofrequency waves, such as those emitted from handheld cellular telephones. Cellular carriers contributed information about 1.5 million telephone account holders, their phones and two months of data on minutes used and number of calls. Cellular telephone manufacturers provided data that allowed classification of phones as analogue or digital and a handheld or mobile (car or bag) for 67% of the phones. Thus far 1,021,767 individuals have been identified who had at least one active cellular telephone account in 1994 and/or 1995 and who used either a handheld (41%) or a mobile (59%) phone during the study period, but not both. Seventy-four per cent of the cohort had used their cellular phone for ≥2 years, and 30% for ≥3 years. (author)

  13. Cellular Telephones, Magnetic Field Exposure, Risk of Brain Tumours and Cancer at Other Sites: A Cohort Study (invited paper)

    International Nuclear Information System (INIS)

    The purpose of the study is to investigate whether exposure to electromagnetic fields from cellular telephones is associated with brain tumours and cancer at other sites. Key information has been obtained on all cellular telephone subscribers in Denmark from 1 January 1982 to 31 December 1995. The overall subscriber cohort will include approximately 500,000 individuals. Collected information includes name of subscriber, address, telephone number, system used (analogue or digital), and annual use of the telephone. The name and address of the subscribers will be linked to the Central Population Register, and the personal identification number will be supplied in addition to information on vital status and migration. Finally, all members of the cohort will be linked to the Danish Cancer Registry, and the observed number of tumours will be compared with those expected on the basis of national cancer incidence rates stratified by sex, age, and calendar time.

  14. Study Design for a Case Control Investigation of Cellular Telephones and Other Risk Factors for Brain Tumors in Adults

    International Nuclear Information System (INIS)

    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.

  16. Effects of high frequency electromagnetic field emitted from digital cellular telephones on electronic pocket dosimeters

    International Nuclear Information System (INIS)

    High frequency electromagnetic fields emitted from digital cellular telephones (cell phones) occasionally cause abnormally high values (wrong dosages) on electronic pocket dosimeters (EPD). Electric field strength distribution around the cell phone transmitting 1.5GHz band with a maximum power of 0.8 W was analyzed by using an isotropic probe with tri-axial dipole antennas. Five kinds of EPDs were exposed to the fields for 50s under four kinds of configurations relative to the cell phone. The electric field distribution expanded around the antenna and had a maximum strength level of 36.5 ± 0.30 V/m. The cell phone gave rise to a wrong dosage of four EPDs out of five. The electromagnetic susceptibility of the EPD was higher in the section where the semiconductor detector or electric circuit boards were implanted. The maximum value of wrong dosage was 1283μ Sv. The distance preventing electromagnetic interference differed in each EPD and ranged from 2.0cm to 21.0cm. The electromagnetic immunity levels of the EPDs were distributed from 9.2V/m to a value greater than 35V/m. The EPDs displayed wrong dosage during exposure, while they recovered their normal performance after the cell phone ceased transmitting. The electromagnetic immunity levels of the EPDs were either equal to or greater than the IEC-standard. The immunity levels should be enhanced greater than the IEC-standard from the standpoint of radiation protection

Five types of electronic pocket dosimeters (EPDs) were exposed to the fields for 50sec under four kinds of configurations relative to the cell phone. The field distribution expanded around the antenna and had a maximum strength level of 36.5±0.3V/m. The cell phone caused abnormally high values (wrong dosages) to four EPDs out of five due to electromagnetic interference. Three out of the four EPDs exceeded the upper limits of dose range depending on the configurations, and the maximum value of wrong dosage among the EPDs was 1,283 μSv. The minimum distance preventing electromagnetic interference (protection distance) differed with each EPD and ranged from 2.0cm to 21.0cm. The electromagnetic immunity levels of EPD-1, 2, 3, 4 and 5 were 13.3, ≥35, ≥32, 9.2 and ≥35 V/m, respectively. Although the immunity levels were either equal to or greater than the IEC-standard level, those of the EPDs should be enhanced greater than the IEC-standard from the standpoint of radiation protection.

    From 1983, when the first cellular network was established, to 1992, the wireless industry grew by ten million customers. From 1993 to 2000, the wireless industry grew by 90 million customers. Today, there are more than 149 million U.S. wireless subscribers. The phenomenal growth of the wireless industry can be traced to several factors. These factors are improvements in cellular technology, expansion of that technology and the allocation of spectrum by the federal government. This thesis ana...

  20. Electric currents and fields induced in cells in the human brain by radiation from hand-held cellular telephones

    Science.gov (United States)

    King, Ronold W. P.

    2000-01-01

    After a review of recent work on the interaction of electromagnetic fields from cellular telephones with the human head, the structural and radiating properties of two common types of transceivers are determined. These include the impedance and current amplitude distribution of the antennas. The tangential electric field maintained by the antennas on the adjacent surface of the head is next determined. From this, the electric field propagating through the skull into the brain is analyzed and, from it, the electric field in spherical and long cylindrical cells is determined. It ranges from 27 to 13.5 V/m in the first 3 cm inside the skull. Of interest is the fact that the induced field in the interior of all cells, regardless of their shape, is the same as the incident field in the brain. It is hoped that biomedical scientists will review these results and determine possible biological effects.

    2013-05-01

    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.

  5. Some present problems and a proposed experimental phantom for SAR compliance testing of cellular telephones at 835 and 1900 MHz

    Science.gov (United States)

    Gandhi, Om P.; Kang, Gang

    2002-05-01

    This paper compares the maximum allowable powers of some typical cellular telephones at 835 and 1900 MHz for compliance with the limits of specific absorption rates (SAR) given in ANSI/IEEE, ICNIRP and the proposed modification of ANSI/IEEE safety guidelines. It is shown that the present ANSI/IEEE guideline is the most conservative with the ICNIRP guidelines allowing a maximum radiated power that is 2.5-3 times higher, and the proposed IEEE modification of treating pinna as an extremity tissue the least conservative allowing even higher radiated powers by up to 50%. The paper also expands the previously reported study of energy deposition in models of adults versus children to two different and distinct anatomically-based models of the adult head, namely the Utah model and the 'Visible Man' model, each of which is increased or reduced by the voxel size to obtain additional head models larger or smaller in all dimensions by 11.1% or -9.1%, respectively. The peak 1 g body-tissue SAR calculated using the widely accepted FDTD method for smaller models is up to 56% higher at 1900 MHz and up to 20% higher at 835 MHz compared to the larger models, with the average models giving intermediate SARs. Also given in the paper is a comparison of the peak 1 g and 10 g SARs for two different anatomically-based models with 6 mm thick smooth plastic ear models used for SAR compliance testing. The SARs obtained with the insulating plastic ear models are up to two or more times smaller than realistic anatomic models. We propose a 2 mm thin shell phantom with lossy ear that should give SARs within +/-15% of those of anatomic models.

    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

    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.

  15. Effect of a hands-free wire on specific absorption rate for a waist-mounted 1.8 GHz cellular telephone handset

    International Nuclear Information System (INIS)

    A common feature of cellular telephony is the use of a 'hands-free' audio extension lead connected to a waist-worn handset. Interaction between the transmitting antenna, the wire and the user's body can occur, with detrimental effects including polar pattern degradation, reduced efficiency and localized increases in specific absorption rate (SAR). Using a realistic full-body model of an adult male, finite difference time domain analysis was employed to investigate the coupling between a hip-mounted 1.8 GHz handset fitted with a monopole antenna and a 1 m long wire representing a hands-free wire. Conduction current densities were computed for three identifiable coupling modes: magnetic-only, conductive-only and combined conductive-and-magnetic. Magnetic-only coupling was dominant. Without the lead, placing the handset at waist height led to a 42.8% increase in the total energy deposited in the body, compared to use at the head. Introducing the lead further increased the body loss, with a reduction in system radiation efficiency from 52% to 43.7%. Without the hands-free lead, the peak 1 g and 10 g SARs were 0.450 W kg-1 and 0.265 W kg-1, respectively, for 125 mW transmit power. With the hands-free lead connected, these values increased to 1.14 W kg-1 and 0.430 W kg-1, respectively

    BRCA1/2 test disclosure has, historically, been conducted in-person by genetics professionals. Given increasing demand for, and access to, genetic testing, interest in telephone and Internet genetic services, including disclosure of test results, has increased. Semi-structured interviews with genetic counselors were conducted to determine interest in, and experiences with telephone disclosure of BRCA1/2 test results. Descriptive data are summarized with response proportions. One hundred and ninety-four genetic counselors completed self-administered surveys via the web. Although 98% had provided BRCA1/2 results by telephone, 77% had never provided pre-test counseling by telephone. Genetic counselors reported perceived advantages and disadvantages to telephone disclosure. Thirty-two percent of participants described experiences that made them question this practice. Genetic counselors more frequently reported discomfort with telephone disclosure of a positive result or variant of uncertain significance (p genetic counselors have provided telephone disclosure, however, most, infrequently. Genetic counselors identify potential advantages and disadvantages to telephone disclosure, and recognize the potential for testing and patient factors to impact patient outcomes. Further research evaluating the impact of testing and patient factors on cognitive, affective, social and behavioral outcomes of alternative models of communicating genetic information is warranted.

    Critical telephone network systems are currently protected from electric utility power failures by a backup system consisting of lead-acid batteries and an engine-alternator. It is considered here an alternate power system where less expensive off-peak commercial electricity electrolyses water, while fuel cells draw continuously on the stored gas products to provide direct current for the protected equipment. The lead acid batteries are eliminated. The benefits and costs of the existing and alternate systems in scenarios with various system efficiencies, capital costs, and electric utility rates and incentives, are compared. In today's conditions, the alternate system is not economical; however, cost and performance feasibility domains are identified. 2 figs., 4 tabs., 12 refs

    2015-06-01

    In this era of global connectedness, there is great interest in using distance video platforms such as Skype and VSee, as well as the telephone, for conducting psychoanalysis and psychotherapy across geographic distance. Little, however, has been written about the use of technology for psychoanalytic education. The International Psychotherapy Institute has extensive experience in the use of videoconference and telephone technology in the teaching of psychoanalysis and psychoanalytic psychotherapy, including didactic teaching, infant observation, and individual and group supervision, with individuals and groups across the United States and overseas. Use of this technology for tele-education has facilitated the spread of psychoanalytic ideas, recruitment of psychoanalytic and psychotherapeutic trainees, and ongoing training for members living at great distances from one another and from the institute. This work is in many ways similar to ordinary psychoanalytic teaching and supervision, and yet presents significant differences in technique, opportunity, and group dynamics. Further implementation and study of this methodology can greatly aid in the dissemination of psychoanalysis in the digital age. PMID:26070477

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

    Directory of Open Access Journals (Sweden)

    Ghasem Mirjalily

    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.

    2013-10-01

    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.

  20. Network of mobile telephone communication: necessarily of 3. Millennium

    International Nuclear Information System (INIS)

    Mobile telephones have transformed the telecommunications industry. These devices can be used to make telephone calls from almost anywhere. There are two types, one has the antenna mounted on the handset and the other has the antenna mounted on a separate transmitter or, if the telephone is installed in a vehicle, mounted on the roof or rear window. Communication between a mobile telephone and the nearest base station is achieved by the microwave emissions from the antenna. Concerns have been raised about the type of mobile telephone that has the antenna in the handset. In this case, the antenna is very close to the user's head during normal use of the telephone and there is concern about the level of microwave emissions to which the brain is being exposed. Those telephones that have the antenna mounted elsewhere are of no concern, since exposure levels decrease rapidly with increasing distance from the antenna. Cordless telephones, which need to be operated within about 20 metres of a base unit that is connected directly to the telephone system, do not have any health concerns associated with their use because exposure levels are very low

  3. When may doctors give nurses telephonic treatment instructions?

    Science.gov (United States)

    McQuoid-Mason, David Jan

    2016-08-01

    Doctors are expected to examine their patients before issuing telephonic instructions to nurses. However, in emergencies or when they are aware of the health status of their patients, it may be justified for a doctor to issue telephonic instructions to nurses without examining the patient. Doctors on call owe a special duty to patients, who they may have to examine or arrange for another doctor to do so before issuing telephonic instructions. In deciding whether doctors acted reasonably in issuing telephonic instructions to nurses, the courts will decide whether they exercised the same degree of skill and care as reasonably competent practitioners in their branch of the profession. Suggestions are made concerning doctors giving telephonic instructions to nurses regarding patients they have not examined. PMID:27499403

    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.

    2016-01-01

    E-mail may rule the world in other types of businesses, but for medical practices, the telephone remains the primary mode of communication with patients, specialists, and pharmacies. From making appointments to calling in prescriptions, telephones are essential to patient care. With technology changing very quickly and new capabilities coming into the medical practice, such as telemedicine and Skype, you need to know your options when choosing a new telephone system. The possibilities include on-site, cloud, and hybrid networked solutions. A wide variety of features and capabilities are available, from dozens of vendors. Of course, no matter what telephone solution you choose, you must meet regulatory compliance, particularly HIPAA, and Payment Card Industry Data Security Standard if you take credit cards. And it has to be affordable, reliable, and long lasting. This article explores what medical practices need to know when choosing a new business telephone system in order to find the right solutions for their businesses. PMID:27443060

    2007-06-01

    Telephone assessments are commonly used in mental health research and may be especially beneficial in older populations. The current study assessed the psychometric properties of the Penn State Worry Questionnaire (T. J. Meyer, M. L. Miller, R. L. Metzger, & T. D. Borkovec, 1990) and the Beck Depression Inventory--II (A. T. Beck, R. A. Steer, & G. K. Brown, 1996), when administered over the telephone in an older adult population. Results indicate no differences in mean symptom level or internal consistency across two modes of administration. Correlations between the in-person and telephone-administered measures and diagnostic categories suggest adequate validity of the telephone-administered measures. With this demonstrated evidence, the telephone assessment method can be applied in a variety of research and clinical settings. PMID:17563195

    2009-01-01

    This study compared the use of Short Message Service (SMS) on mobile phones and the use of telephone interviews in collecting self-reported data about influenza vaccination. Through random selection from the Swedish population registry, 2,400 individuals were assigned to be contacted through SMS (SMS-group), and 2,150 were assigned to undergo personal telephone interviews (TI-group). Both groups were asked three questions about influenza and influenza vaccination. Mobile phone numbers were found for 1,055 persons in the SMS-group of whom 154 (6% of the original sample; 15% of all who had a listed mobile phone number) responded. Landline or mobile phone numbers were found for 1,636 persons in the TI-group and 1,009 (47% of the original TI sample; 62% of those where a telephone number was found) responded. The vaccination data collected via SMS was not statistically significantly different from data collected through telephone interviews, and adjustment for different background factors did not change this. Compared to the original sample, there was an under representation of elderly and less educated individuals among the participants in the SMS-group, and under representation of less educated in the TI-group. Though the participation rate was low, SMS is a feasible method for collection of information on vaccination status data among the Swedish population compared to telephone interviews. PMID:19082745

  8. Microwave radiation safety assessment around mobile telephone base station (MTBS) in Peninsular Malaysia

    International Nuclear Information System (INIS)

    Mobile telephone is one of the fastest popular consumer product introduced in the market. Since more people are using mobile telephone, the number of mobile telephone base station (MTBS) in Malaysia had also increased in order to provide a better coverage services to consumer. The antennas that are required for the mobile (or cellular) telephone network are located at MTBS. This antenna emits radio frequency (RF) and microwave (MW) radiation. Due to the concerns that has been raised by the people that are living or working nearby to MTBS about the possibility of adverse health effects that might occur due to the exposure of this radiation, a project of microwave radiation safety assessment around MTBS by MINT was carried out (September 2003 - January 2006). It was involved with 128 MTBS from three biggest service providers in Malaysia. This assessment is required to establish a baseline data in term of pattern and trend of the radiation emission from the facilities as well as to develop a public confident. In this paper, it will describe the fact that radiation is critical to the MTBS system and without the radiation, the MTBS system is functionless. It will also highlight the result of the assessment's work that has been carried out by MINT around MTBS mounted on the rooftops and towers. The average reading varies between the detection limit of the instrument 2 (2 (7.204 V/m). The highest average reading corresponds to about 2.0% of the Suruhanjaya Komunikasi dan Multimedia Malaysia (MCMC) exposure limit for public. The finding of this measurement confirms that the presence of RF and MW radiation in public accessible area around the base station was very low and comparable to the radiation levels in other places away from MTBS. There is also no evidence, from any laboratory or epidemiology studies that the exposure to RF energy levels recommended limits has any health significance for humans. (Author)

    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.

    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

  20. Radiations FR of telephone antennas and Public health: the state of the art

    International Nuclear Information System (INIS)

    Today, mobile telephone is envisioned as one of the most significant innovations in communication. The growing development of this system asks for increasing amounts of antennas, installed in base transceiver stations (BTS) connection mobile stations (MS, hand held phones) to each other and to the conventional telephone network. Depending on the area, antennas are generally mounted in BTS located either on the top of buildings (in urban areas) or in towers (in rural or less populated areas). In both of the cases, the visual impact of BTS is significant for people living or working close to them. This visual evidence, together with some information, usually inconsistent or incomplete, released in media other than the scientific literature, have generated increasing feelings of phobia to alleged detrimental consequences of the uncontrolled exposure to radio waves emitted by the antennas. Such feelings, identified previously in countries where mobile telephony has been used for years in a regular basis, are now significantly growing in Spain and motivate many of the questions asked to information services of public agencies and institutions. The aim of the present article is to address some of the most frequently asked questions on the topic and to review the state of the art of our knowledge on the putative effects of the exposure to the electromagnetic radiation emitted by the aerials. Also, elementary notions are provided on the functioning of mobile telephony that may help the reader to better understand some technical aspects concerning the topic. (Author) 54 refs

  3. Bandwidth Extension of Telephone Speech Aided by Data Embedding

    Directory of Open Access Journals (Sweden)

    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.

    2015-01-01

    Cellular resilience describes the ability of a cell to cope with environmental changes such as toxicant exposure. If cellular metabolism does not collapse directly after the hit or end in programmed cell death, the ensuing stress responses promote a new homeostasis under stress. The processes of reverting "back to normal" and reversal of apoptosis ("anastasis") have been studied little at the cellular level. Cell types show astonishingly similar vulnerability to most toxicants, except for those that require a very specific target, metabolism or mechanism present only in specific cell types. The majority of chemicals triggers "general cytotoxicity" in any cell at similar concentrations. We hypothesize that cells differ less in their vulnerability to a given toxicant than in their resilience (coping with the "hit"). In many cases, cells do not return to the naive state after a toxic insult. The phenomena of "pre-conditioning", "tolerance" and "hormesis" describe this for low-dose exposures to toxicants that render the cell more resistant to subsequent hits. The defense and resilience programs include epigenetic changes that leave a "memory/scar" - an alteration as a consequence of the stress the cell has experienced. These memories might have long-term consequences, both positive (resistance) and negative, that contribute to chronic and delayed manifestations of hazard and, ultimately, disease. This article calls for more systematic analyses of how cells cope with toxic perturbations in the long-term after stressor withdrawal. A technical prerequisite for these are stable (organotypic) cultures and a characterization of stress response molecular networks. PMID:26536287

  19. Evaluation of routine telephone transmission of nuclear medicine studies

    International Nuclear Information System (INIS)

    Rapid and reliable transmission of nuclear medicine studies using conventional telephone lines and commercially available modems and computer systems has been accomplished through use of software developed within the authors' hospital. Original digital images of all-night and weekend studies, acquired on any of the acquisition computers from different manufacturers, are now routinely sent for remote reading at the physician's home. Data, software, and letters are routinely exchanged using modems and standard telephone lines with a sister institution in Haifa, Israel. The software has been designed to achieve no loss data compression and minimal turnaround time loss. Thus, an average lung perfusion image or gallbladder study requires about 1-3 minutes of transmission time. Full analysis and display software is available on the remote computer

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 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

    2008-09-01

    Full Text Available Abstract Background Baseline data is necessary for monitoring how a population perceives the threat of pandemic influenza, and perceives how it would behave in the event of pandemic influenza. Our aim was to develop a module of questions for use in telephone health surveys on perceptions of threat of pandemic influenza, and on preparedness to comply with specific public health behaviours in the event of pandemic influenza. Methods A module of questions was developed and field tested on 192 adults using the New South Wales Department of Health's in-house Computer Assisted Telephone Interviewing (CATI facility. The questions were then modified and re field tested on 202 adults. The module was then incorporated into the New South Wales Population Health Survey in the first quarter of 2007. A representative sample of 2,081 adults completed the module. Their responses were weighted against the state population. Results The reliability of the questions was acceptable with kappa ranging between 0.25 and 0.51. Overall 14.9% of the state population thought pandemic influenza was very or extremely likely to occur; 45.5% were very or extremely concerned that they or their family would be affected by pandemic influenza if it occurred; and 23.8% had made some level of change to the way they live their life because of the possibility of pandemic influenza. In the event of pandemic influenza, the majority of the population were willing to: be vaccinated (75.4%, be isolated (70.2%, and wear a face mask (59.9%. People with higher levels of threat perception are significantly more likely to be willing to comply with specific public health behaviours. Conclusion While only 14.9% of the state population thought pandemic influenza was very or extremely likely to occur, a significantly higher proportion were concerned for self and family should a pandemic actually occur. The baseline data collected in this survey will be useful for monitoring changes over time in the

    2003-03-01

    A given question can be defined in terms of the set of statements or assertions that answer it. Application of logical inference to these sets of assertions allows one to derive the logic of inquiry among questions. There are interesting symmetries between the logics of inference and inquiry; where probability describes the degree to which a premise implies an assertion, there exists an analogous measure that describes the bearing or relevance that a question has on an outstanding issue. These have been extended to suggest that the logic of inquiry results in functional relationships analogous to, although more general than, those found in information theory. Employing lattice theory, I examine in greater detail the structure of the space of assertions and questions demonstrating that the symmetries between the logical relations in each of the spaces derive directly from the lattice structure. Furthermore, I show that while symmetries between the spaces exist, the two lattices are not isomorphic. The lattice of assertions is described by a Boolean lattice 2N, whereas the lattice of assuredly real questions is shown to be a sublattice of the free distributive lattice FD(N) = 22N. Thus there does not exist a one-to-one mapping of assertions to questions, there is no reflection symmetry between the two spaces, and questions in general do not possess complements. Last, with these lattice structures in mind, I discuss the relationship between probability, relevance, and entropy.

    Full Text Available Objective‐ The study examined whether a prompt sheet improved the reference interview process for health information advisers working at NHS Direct, a 24‐hour telephone helpline that provides confidential health care advice for the public in England.Methods ‐ A randomised control trial was conducted at eight NHS Direct sites across England in 2003‐04. Newly recruited health information advisers (n=30, full and part‐time,were randomly allocated to a control group (n=15 or intervention group (n=15, and 26 completed the study. Existing health information advisers were involved in the planning and design of the intervention. The prompt sheet included prompts for demographic information, reason for call, condition/treatment plan, existing knowledge of caller, special needs of the caller, handling a call empathetically, and conclusion. Testing of reference interview expertise was done at the end of basic training, and two months later, using the same questions. The ten test questions were based on common questions received by NHS Direct. A relevance framework for possible responses was drawn up for each question for scoring test responses, with more relevant responses scoring higher than less relevant responses.Results‐ The average score of prompt (experimental and non‐prompt (control participants increased on the second test, for each of the 10 questions. The prompt group improved significantly more overall than the control group. There was variation within the groups.

    This document, prepared in February 1993, addresses the most common questions asked by APS Collaborative Access Teams (CATs). The answers represent the best judgment on the part of the APS at this time. In some cases, details are provided in separate documents to be supplied by the APS. Some of the answers are brief because details are not yet available. The questions are separated into five categories representing different aspects of CAT interactions with the APS: (1) Memorandum of Understanding (MOU), (2) CAT Beamline Review and Construction, (3) CAT Beamline Safety, (4) CAT Beamline Operations, and (5) Miscellaneous. The APS plans to generate similar documents as needed to both address new questions and clarify answers to present questions

  1. What is a Question?

    CERN Document Server

    Knuth, K H

    2002-01-01

    A given question can be defined in terms of the set of statements or assertions that answer it. Application of logical inference to these sets of assertions allows one to derive the logic of inquiry among questions. There are interesting symmetries between the logics of inference and inquiry; where probability describes the degree to which a premise implies an assertion, there exists an analogous measure that describes the bearing or relevance that a question has on an outstanding issue. These have been extended to suggest that the logic of inquiry results in functional relationships analogous to, although more general than, those found in information theory. Employing lattice theory, I examine in greater detail the structure of the space of assertions and questions demonstrating that the symmetries between the logical relations in each of the spaces derive directly from the lattice structure. Furthermore, I show that while symmetries between the spaces exist, the two lattices are not isomorphic. The lattice ...

    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

    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.

    Physical disability threatens a person's life style and can be detrimental in its effects on mood and activity. We describe a counseling program for severely disabled persons who were involved in telephone support groups in order to solve problems related to feeling discouraged, lonely, or being too inactive to remain healthy. A majority of the participants reported being less anxious and more socially involved as a result of the intervention. Ease with which groups were conducted and positive feedback from participants suggests that research should evaluate the cost effectiveness of phone intervention and explore potential of treating affective problems with scheduled phone contact.

    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.

Historically they were studied under synchronous dynamics where all the cells of the system are updated at each time step. Meanwhile the question of probabilistic dynamics emerges: on the one hand, to develop cellular automata which are capable of reliable computation even when some random errors occur; on the other hand, because synchronous dynamics is not a reasonable assumption to simulate re...

    2012-02-01

    There is professional consensus that teleanalysis, the practice of psychoanalysis conducted remotely using the telephone and the Internet, is increasing in response to more mobility in the population. But there is controversy as to whether the use of technology leads to a dilution of analysis or to adaptive innovation that is clinically effective and true to the tenets of psychoanalysis. The author reviews the psychoanalytic literature and shows the development of analytic thinking about this technology-assisted practice of psychoanalysis. She summarizes analysts' perceptions and experiences of the advantages and disadvantages, and considers the indications and contra-indications. She focuses on the clinical concerns that arise in terms of the frame, resistance, and the development of analytic process through the unconscious communication of internal objects, unconscious fantasy, transference and countertransference. She gives vignettes from the analysis of a man with trauma-related depression to address the concerns raised and to support her argument that analysis using the telephone and the Internet is a viable, clinically effective alternative to traditional analysis where necessary.

    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

    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.

  3. Radiation safety assessment of mobile telephone base stations

    International Nuclear Information System (INIS)

    Mobile telephone is fast getting popular among users and in fact it has become one of the fastest selling electronic products in the world. More base stations are expected to be built to meet such high demands and this has caused great concerned among members of the public, especially those living close to the stations, about the potential harmful health effects of radiofrequency (RF) radiation produced by such facilities. A project was initiated by MINT in early 2000 with aims to assess the radiation levels present in the areas around the base stations and to establish baseline data on the pattern and trend of the radiation emission from each different set up of the facilities. This paper highlights some basics facts about mobile telephones and preliminary findings of the project. The assessment has been carried out at 16 base station sites and the results indicate that the radiation levels present around these sites are very low. Their broadband readings vary between below the detection limit of 0.3μWatts/cm2 to 11 μWatts/cm2 and they are comparable to normal background radiation present in places away from any base stations. The highest level observed was 1.5% of the exposure limit recommended for members of the public. However, locations at close distance in front of the the antenna can be very serious in term of radiation exposure since the radiation level here can easily exceed the permissible exposure limit for public. Safety precaution needs to be taken when entering these areas and they should be out of bound for members of the public. (Author)

  4. Quantum theory from questions

    Hoehn, Philipp A

    2016-01-01

    We reconstruct the explicit formalism of qubit quantum theory from elementary rules on an observer's information acquisition. Our approach is purely operational: we consider an observer O interrogating a system S with binary questions and define S's state as O's `catalogue of knowledge' about S; no ontic assumptions are necessary. From the rules we derive the state spaces for N qubits and show that (a) they coincide with the set of density matrices over N qubit Hilbert spaces; (b) states evolve unitarily under the group $\\rm{PSU}(2^N)$ according to the von Neumann evolution equation; and (c) the binary questions by means of which O interrogates the systems corresponds to projective measurements on Pauli operators with outcome probabilities given by the Born rule. Besides offering a novel conceptual perspective on qubit quantum theory, the reconstruction also unravels new structural insights. Namely, we show that, in a quadratic information measure, (d) qubits satisfy informational complementarity inequalities...

  5. The Question Concerning Thinking

    Riis, Søren

    2008-01-01

    Martin Heidegger's thought-provoking essay "The Question Concerning Technology" (1977a) placed technology at the heart of philosophy. Heidegger tried to show that the essence of technology provokes humans to think about the world in a very dangerous way. Yet if we follow Heidegger's analysis of...... technology, what role does that ascribe to philosophy? To be able to understand the programmatic scope of Heidegger's question ‘concerning' technology, we need to see it as inseparable from his famous thesis about the end of philosophy (1977c) and what he considers to be the ideal kind of thinking. However......, by doing so, we will in the end realize two important things. First, that Heidegger's declaration of the end of philosophy in fact also means the end of anything we can meaningfully call thinking. Second, that Heidegger's own thinking is completely different from his own ideal of thinking. Our...

    2013-01-01

    The only experimentally observed phenomenon that lies outside the standard model of the electroweak interaction is neutrino oscillations. A way to try to unify the extensive neutrino oscillation data is to add a phenomenological mass term to the Lagrangian that is not diagonal in the flavor basis. The goal is then to understand the world's data in terms of the parameters of the mixing matrix and the differences between the squares of the masses of the neutrinos. An outstanding question is what is the correct ordering of the masses, the hierarchy question. We point out a broken symmetry relevant to this question, the symmetry of the simultaneous interchange of hierarchy and the sign of $\\theta_{13}$. We first present the results of an analysis of data that well determine the phenomenological parameters but are not sensitive to the hierarchy. We find $\\theta_{13} = 0.152\\pm 0.014$, $\\theta_{23} = 0.25^{+0.03}_{-0.05} \\pi$ and $\\Delta_{32} = 2.45\\pm 0.14 \\times 10^{-3}$ eV$^2$, results consistent with others. We...

  6. The number of simple modules of a cellular algebra

    Institute of Scientific and Technical Information of China (English)

    LI Weixia; XI Changchang

    2005-01-01

    Let n be a natural number, and let A be an indecomposable cellular algebra such that the spectrum of its Cartan matrix C is of theform {n, 1,..., 1}. In general, not every natural number could be the number of non-isomorphic simple modules over such a cellular algebra. Thus, two natural questions arise: (1) which numbers could be the number of non-isomorphic simple modules over such a cellular algebra A ? (2) Given such a number, is there a cellular algebra such that its Cartan matrix has the desired property ? In this paper, we shall completely answer the first question, and give a partial answer to the second question by constructing cellular algebras with the pre-described Cartan matrix.

    2009-01-01

    Full Text Available This study investigated students’ preference on teacher’s questions and questionings techniques and more importantly on how they could facilitate or impede their learning. The results on teacher’s questioning techniques showed that random nomination was more preferred than pre-arranged format nomination. In addition, techniques of nominating volunteering students and of giving wait-time were disliked by most student-respondents. As for types of question, the yes/no question was favored by most of the respondents. Different from the yes/no question, the number of respondents leaning forward to the analysis question, questions about fact of life, and questions to state opinion did not show a significant difference from the number of those leaning against the same questions.

    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.

  11. Trick questions: cosmopolitan hospitality

    Directory of Open Access Journals (Sweden)

    Eleanor Byrne

    2013-08-01

    Full Text Available Byrne’s paper consists of two parallel texts. The first explores the limits of cosmopolitanism in practice, taking as its subject the Life in the UK Citizenship Test, inaugurated under the Labour Government in 2005. It argues that the test exemplifies the predicament of all attempts at cosmopolitan hospitality as unconditional welcoming, through a discussion of the relation between questioning and welcoming the stranger. Establishing the relationship between cosmopolitanism and hospitality as envisaged in Derrida’s reading of Kant it asks what kind of cosmopolitan hospitality is either possible or desirable by exploring what Derrida calls the ‘perversions’ inherent in the structures of hospitality. It focuses on the concept of the ‘trick questions’ that the state asks the foreigner observed by Derrida in his reading of The Apology of Socrates; questions that seem to invite answers but foreclose the possibilities of a free response. The second text asks how this logic that Derrida identifies can be pushed or coaxed into new ways of addressing the perceived threats of ‘unconditional’ hospitality through a reading of ‘unconditional hospitality’ as queer in the work of Tove Jansson.

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

    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

    International Nuclear Information System (INIS)

    Initially considered as the supreme weapon against greenhouse gas emissions, biofuels are today hold responsible to all harms of the Earth: leap of agriculture products price, deforestation, food crisis. Considered some time ago as the perfect clean substitute to petroleum, biofuels are now suspected to have harmful effects on the environment. Should it be just an enormous technical, environmental and human swindle? Should we abandon immediately biofuels to protect the earth and fight the threatening again starvation? Should we wait for the second generation of efficient biofuels, made from non food-derived products and cultivation wastes? This book analyses this delicate debate through 5 main questions: do they starve the world? Are they a clean energy source? Do they contribute to deforestation? Are they economically practicable? Is the second generation ready? (J.S.)

    Thousands of lives are lost every year in developing countries for failing to detect epidemics early because of the lack of real-time disease surveillance data. We present results from a large-scale deployment of a telephone triage service as a basis for dengue forecasting in Pakistan. Our system uses statistical analysis of dengue-related phone calls to accurately forecast suspected dengue cases 2 to 3 weeks ahead of time at a subcity level (correlation of up to 0.93). Our system has been operational at scale in Pakistan for the past 3 years and has received more than 300,000 phone calls. The predictions from our system are widely disseminated to public health officials and form a critical part of active government strategies for dengue containment. Our work is the first to demonstrate, with significant empirical evidence, that an accurate, location-specific disease forecasting system can be built using analysis of call volume data from a public health hotline.

    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)

    There is no doubt that nanoscience will be the dominant direction for technology in this century, and that this science will influence our lives to a large extent as well as open completely new perspectives on all scientific and technological disciplines. To be able to produce optimal nanosystems with tailor-made properties, it is necessary to analyze and construct such systems in advance by adequate theoretical and computational methods. Since we work in nanoscience and nanotechnology at the ultimate level, we have to apply the basic laws of physics. What methods and tools are relevant here? The book gives an answer to this question. The background of the theoretical methods and tools is critically discussed, and also the world view on which these physical laws are based. Such a debate is not only of academic interest but is of highly general concern, and this is because we constantly move in nanoscience and nanotechnology between two extreme poles, between infinite life and total destruction .

  20. Cosmic questions: an introduction.

    Science.gov (United States)

    Primack, J R; Abrams, N E

    2001-12-01

    This introductory talk at the Cosmic Questions conference sponsored by the AAAS summarizes some earlier pictures of the universe and some pictures based on modern physics and cosmology. The uroboros (snake swallowing its tail) is an example of a traditional picture. The Biblical flat-earth picture was very different from the Greek spherical earth-centered picture, which was the standard view until the end of the Middle Ages. Many people incorrectly assume that the Newtonian picture of stars scattered through otherwise empty space is still the prevailing view. Seeing Earth from space shows the power of a new picture. The Hubble Space Telescope can see all the bright galaxies, all the way to the cosmic Dark Ages. We are at the center of cosmic spheres of time: looking outward is looking backward in time. All the matter and energy in the universe can be represented as a cosmic density pyramid. The laws of physics only allow the material objects in the universe to occupy a wedge-shaped region on a diagram of mass versus size. All sizes--from the smallest size scale, the Planck scale, to the entire visible universe--can be represented on the Cosmic Uroboros. There are interesting connections across this diagram, and the human scale lies in the middle. PMID:11797741

  1. 101 questions about energy

    International Nuclear Information System (INIS)

    Today, energy in the center of the world events. People get swamped with information about energy, environment, energy saving or renewable energy sources. However, the solutions proposed are still in the centre of debates and no consensus exists which allows to define a clear policy: nuclear energy or wind power? Solar energy or biomass fuels? And what about the meaning of the expression 'clean coal'? And why oil prices go up and down while it is said that the resource is close to exhaustion? Mass media are trying to tell us that 'urgency is here', mainly because of the climatic threat of greenhouse gases and because of a world economy totally dependent of politically unstable areas, like Middle East, Africa or Caucasus, but with huge oil and gas resources. And what about Europe, and what about all this gas in Russia? It is hard for a non-specialist to find his way in this complex domain. This is the aim of this book which has opted for the non-politically correct attitude to answer 101 key-questions about the energy topic: Europe's security of supply, energy geopolitics, oil future, energy crises, sustainable development etc. (J.S.)

    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

    This study proposed a new information and commutation technology assisted blind telephone interview (ICT-ABTI) system to help visually impaired people to do telephone interview jobs as normal sighted people and create more diverse employment opportunities for them. The study also used an ABAB design to assess the system with seven visually impaired people. As the results, they can accomplish 3070 effective telephone interviews per month independently. The results also show that working performance of the visually impaired can be improved effectively with appropriate design of operation working flow and accessible software. The visually impaired become productive, lucrative, and self-sufficient by using ICT-ABTI system to do telephone interview jobs. The results were also shared through the APEC Digital Opportunity Center platform to help visually impaired in Philippines, Malaysia and China. PMID:25209925

    1978-11-01

    A follow-up study on pacemaker function in 15 patients with implanted cardiac pacemaker has been performed by telephone transmission. The transmitting set consisting of electrocardiograph, pacemaker pulse modulator and acoustic coupler was manipulated by the patients themselves. ECG, pacemaker pulse, and pulse rate were simultaneously transmitted through 1 channel to the receiver in our clinic. Of 56 patients with pacemaker, 15 patients were surveyed by telephone transmission. In these patients battery exhaustion was detected in 3, competition in 2, and lead fracture in 1. The fact that surveillance and follow-up of the patients with implanted cardiac pacemaker could be carried out by telephone transmission as well as by clinic visitation tells us that the telephone transmission is a useful method and plays an important role in a pacemaker clinic. Moreover our study established its further usefulness in the patient's preference due to difficulties in travelling to the pacemaker clinic and in reducing patient's anxiety. PMID:750667

  13. Yucca Mountain Socioeconomic Project: The 1991 Nevada State telephone survey: Key findings

    International Nuclear Information System (INIS)

    The 1991 Nevada State Telephone Survey was implemented by Decision Research on behalf of the State of Nevada, Agency for Nuclear Projects/Nuclear Waste Project Office (NWPO) as part of an ongoing socioeconomic impact assessment study. The scope of this survey was considerably smaller than a previous survey conducted in 1989 and focused more upon public evaluations of the Yucca Mountain repository program and the trust Nevadans currently addressing the siting issues. In order to provide place in key public officials who are Longitudinal data on the repository program, the 1991 questionnaire consisted of questions that were used in the 1989 NWPO survey which was conducted by Mountain West Research. As a result, the findings from this survey are compared with analogous items from the 1989 survey, and with the results from a survey commissioned by the Las Vegas Review-Journal and reported in their issue of October 21, 1990. The Review-Journal survey was conducted by Bruce Merri11 of the Arizona State University Media Research Center. A more complete comparison of the 1989 and 1991 surveys sponsored by NWPO is possible since the researchers at Decision Research had access to both these databases. The only source of information for the Review-Journal findings was the articles published in the Fall, 1990. The findings of the 1991 survey show that Nevadans oppose the federal government attempts to locate a high-level radioactive waste repository at Yucca Mountain. They support a policy of opposition on the part of Nevada officials. They believe that Nevadans should have the final say in whether to accept the repository or not, and they reject the proposition that benefits from the repository program will outweigh the harms. These findings are very similar to survey results from 1989 and 1990 and once again demonstrate very widespread public opposition by Nevadans to the current federal repository program

    The cellular reflectarray antenna is intended to replace conventional parabolic reflectors that must be physically aligned with a particular satellite in geostationary orbit. These arrays are designed for specified geographical locations, defined by latitude and longitude, each called a "cell." A particular cell occupies nominally 1,500 square miles (3,885 sq. km), but this varies according to latitude and longitude. The cellular reflectarray antenna designed for a particular cell is simply positioned to align with magnetic North, and the antenna surface is level (parallel to the ground). A given cellular reflectarray antenna will not operate in any other cell.

    2016-01-01

    The pathogenesis of cardiomyopathy and heart failure (HF) is underpinned by complex changes at subcellular, cellular and extracellular levels in the ventricular myocardium. For all of the gains that conventional treatments for HF have brought to mortality and morbidity, they do not adequately address the loss of cardiomyocyte numbers in the remodeling ventricle. Originally conceived to address this problem, cellular transplantation for HF has already gone through several stages of evolution over the past two decades. Various cell types and delivery routes have been implemented to positive effect in preclinical models of ischemic and nonischemic cardiomyopathy, with pleiotropic benefits observed in terms of myocardial remodeling, systolic and diastolic performance, perfusion, fibrosis, inflammation, metabolism and electrophysiology. To a large extent, these salubrious effects are now attributed to the indirect, paracrine capacity of transplanted stem cells to facilitate endogenous cardiac repair processes. Promising results have also followed in early phase human studies, although these have been relatively modest and somewhat inconsistent. This review details the preclinical and clinical evidence currently available regarding the use of pluripotent stem cells and adult-derived progenitor cells for cardiomyopathy and HF. It outlines the important lessons that have been learned to this point in time, and balances the promise of this exciting field against the key challenges and questions that still need to be addressed at all levels of research, to ensure that cell therapy realizes its full potential by adding to the armamentarium of HF management.

    We discuss a study to evaluate the extent to which free-response questions could be approximated by multiple-choice equivalents. Two carefully designed research-based multiple-choice questions were transformed into a free-response format and administered on the final exam in a calculus-based introductory physics course. The original multiple-choice questions were administered in another similar introductory physics course on final exam. Findings suggest that carefully designed multiple-choice questions can reflect the relative performance of the free-response questions while maintaining the benefits of ease of grading and quantitative analysis, especially if the different choices in the multiple-choice questions are weighted to reflect the different levels of understanding that students display.

    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

    2015-03-01

    Full Text Available “The Socratic method” is a way of teaching philosophical thinking and knowledge by asking questions. It was first used by in ancient times by the Greek philosopher Socrates who taught his followers by asking questions; these conversations between them are known as “Socratic dialogues”. In this methodology, no new knowledge is taught to the individual; rather, the individual is guided to remember and rediscover what was formerly known through this process. The main method used in cognitive therapy is guided discovery. There are various methods of guided discovery in cognitive therapy. The form of verbal exchange between the therapist and client which is used during the process of cognitive behavioral therapy is known as “socratic questioning”. In this method the goal is to make the client rediscover, with a series of questions, a piece of knowledge which he could otherwise know but is not presently conscious of. The Socratic Questioning consists of several steps, including: identifying the problem by listening to the client and making reflections, finding alternatives by examining and evaluating, reidentification by using the newly rediscovered information and questioning the old distorted belief, and reaching a new conclusion and applying it. Question types used during these procedures are: questions for collecting information, questions revealing meanings, questions revealing beliefs, questions about behaviours during similar past experiences, analytic questions and analytic synthesis questions. In order to make the patient feel understood, it is important to be empathetic and summarize the problem during the interview. In this text, steps of Socratic Questioning-Guided Discovery will be reviewed with sample dialogues provided for each step.

    Full Text Available Abstract Background Many types of research on dementia and cognitive impairment require large sample sizes. Detailed in-person assessment using batteries of neuropyschologic testing is expensive. This study evaluates whether a brief telephone cognitive assessment strategy can reliably classify cognitive status when compared to an in-person "gold-standard" clinical assessment. Methods The gold standard assessment of cognitive status was conducted at the University of Southern California Alzheimer Disease Research Center (USC ADRC. It involved an examination of patients with a memory complaint by a neurologist or psychiatrist specializing in cognitive disorders and administration of a battery of neuropsychologic tests. The method being evaluated was a multi-staged assessment using the Telephone Interview of Cognitive Status-modified (TICSm with patients and the Telephone Dementia Questionnaire (TDQ with a proxy. Elderly male and female patients who had received the gold standard in-person assessment were asked to also undergo the telephone assessment. The unweighted kappa statistic was calculated to compare the gold standard and the multistage telephone assessment methods. Sensitivity for classification with dementia and specificity for classification as normal were also calculated. Results Of 50 patients who underwent the gold standard assessment and were referred for telephone assessment, 38 (76% completed the TICS. The mean age was 78.1 years and 26 (68% were female. When comparing the gold standard assessment and the telephone method for classifying subjects as having dementia or no dementia, the sensitivity of the telephone method was 0.83 (95% confidence interval 0.36, 1.00, the specificity was 1.00 (95% confidence interval 0.89,1.00. Kappa was 0.89 (95% confidence interval 0.69, 1.000. Considering a gold-standard assessment of age-associated memory impairment as cognitive impairment, the sensitivity of the telephone approach is 0.38 (95

  11. 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.

    Directory of Open Access Journals (Sweden)

    McKenzie-McHarg Kirstie

    2011-03-01

    Full Text Available Abstract Background Postnatal depression (PND can be experienced by 13% of women who give birth, and such women often exhibit disabling symptoms, which can have a negative effect on the mother and infant relationship, with significant consequences in terms of the child's later capacity for affect regulation. Research has shown that providing support to mothers experiencing PND can help reduce their depressive symptoms and improve their coping strategies. The Mums4Mums study aims to evaluate the impact of telephone peer-support for women experiencing PND. Methods/Design The study design adopts the MRC framework for the development and evaluation of complex interventions. Health visitors in Warwickshire and Coventry Primary Care Trusts are screening potential participants at the 8-week postnatal check using either the Edinburgh Postnatal Depression Scale (EPDS > = 10 or the three Whooley questions recommended by NICE (http://guidance.nice.org.uk/CG45. The Mums4Mums telephone support intervention is being delivered by trained peer-supporters over a period of four months. The primary outcome is depressive symptomatology as measured by the Edinburgh Postnatal Depression Scale. Secondary outcomes include mother-child interaction, dyadic adjustment, parenting sense of competence scale, and self-efficacy. Maternal perceptions of the telephone peer-support are being assessed using semi-structured interviews following the completion of the intervention. Discussion The proposed study will develop current innovative work in peer-led support interventions and telecare by applying existing expertise to a new domain (i.e. PND, testing the feasibility of a peer-led telephone intervention for mothers living with PND, and developing the relationship between the lay and clinical communities. The intervention will potentially benefit a significant number of patients and support a future application for a larger study to undertake a full evaluation of the clinical

    Esnaashari, Mehdi; Meybodi, Mohammad Reza

    2015-08-01

    Cellular learning automaton (CLA) is a recently introduced model that combines cellular automaton (CA) and learning automaton (LA). The basic idea of CLA is to use LA to adjust the state transition probability of stochastic CA. This model has been used to solve problems in areas such as channel assignment in cellular networks, call admission control, image processing, and very large scale integration placement. In this paper, an extension of CLA called irregular CLA (ICLA) is introduced. This extension is obtained by removing the structure regularity assumption in CLA. Irregularity in the structure of ICLA is needed in some applications, such as computer networks, web mining, and grid computing. The concept of expediency has been introduced for ICLA and then, conditions under which an ICLA becomes expedient are analytically found. PMID:25291810

    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.

    Aging and longevity are controlled by a multiplicity of molecular and cellular signaling events that interface with environmental factors to maintain cellular homeostasis. Modulation of these pathways to extend life span, including insulin-like signaling and the response to dietary restriction, identified the cellular machineries and networks of protein homeostasis (proteostasis) and stress resistance pathways as critical players in the aging process. A decline of proteostasis capacity during aging leads to dysfunction of specific cell types and tissues, rendering the organism susceptible to a range of chronic diseases. This volume of the Annual Review of Biochemistry contains a set of two reviews addressing our current understanding of the molecular mechanisms underlying aging in model organisms and humans.

    1994-04-01

    Full Text Available A policy question is a request for a fairly stable, but modifiable authoritative line of action aimed at securing an optimal balance between different goods, all of which must be pursued, but cannot be jointly maximized. To such questions there are no purely technical solutions, a point that is revealed by the etiology of policy questions. They appear to arise from conflicts among humans over the distribution of goods, i.e., conflicts of interest. However, the deeper roots of such questions lie not in a conflict of human interests, but in the incompatibility of the actual goods that human beings seek. Policy questions ask how to allocate such goods. But this allocation is the business of politics. No policy without politics nor politics without polity.

  2. Dynamic Topology Re-Configuration in Multihop Cellular Networks Using Sequential Genetic Algorithm

    B.Shantha Kumari

    2014-10-01

    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

    Rotavirus is a leading cause of death due to diarrhea among young children across the globe. Despite the limited coding capacity that is characteristic of RNA viruses, rotavirus dedicates substantial resources to avoiding the host innate immune response. Among these strategies is use of the interferon antagonist protein NSP1, which targets cellular proteins required for interferon production to be degraded by the proteasome. Although numerous cellular targets have been described, there remain many questions about the mechanism of NSP1 activity and its role in promoting replication in specific host species. PMID:27009959

    The Western Electric Company produced a multi-line telephone during the 1940s-1970s using a six-button interface design that provided robust tactile, haptic and auditory cues regarding the "state" of the communication system. This multi-line telephone was used as a model for a trade study comparison of two interfaces: a touchscreen interface (iPad)) versus a pressure-sensitive strain gauge button interface (Phidget USB interface controllers). The experiment and its results are detailed in the authors' AES 133rd convention paper " Multimodal Information Management: Evaluation of Auditory and Haptic Cues for NextGen Communication Dispays". This Engineering Brief describes how the interface logic, visual indications, and auditory cues of the original telephone were synthesized using MAX/MSP, including the logic for line selection, line hold, and priority line activation.

    Full Text Available Abstract Background Telephone quit lines are accessible to many smokers and are used to engage motivated smokers to make quit attempts. Smoking cessation counselling provided via telephone can either be reactive (i.e. primarily involving the provision of evidence-based information, or proactive (i.e. primarily involving repeated, sequenced calls from and interaction with trained cessation counsellors. Some studies have found proactive telephone counselling more effective and this trial will investigate whether or not proactive telephone support for smoking cessation, delivered through the National Health Service (NHS Smoking Helpline is more effective or cost-effective than reactive support. It will also investigate whether or not providing nicotine replacement therapy (NRT, in addition to telephone counselling, has an adjunctive impact on smoking cessation rates and whether or not this is cost effective. Methods This will be a parallel group, factorial design RCT, conducted through the English national NHS Smoking Helpline which is run from headquarters in Glasgow. Participants will be smokers who call the helpline from any location in England and who wish to stop smoking. If 644 participants are recruited to four equally-sized trial groups (total sample size = 2576, the trial will have 90% power for detecting a treatment effect (Odds Ratio of 1.5 for each of the two interventions: i proactive versus reactive support and ii the offer of NRT versus no offer. The primary outcome measure for the study is self-reported, prolonged abstinence from smoking for at least six months following an agreed quit date. A concurrent health economic evaluation will investigate the cost effectiveness of the two interventions when delivered via a telephone helpline. Discussion The PORTSSS trial will provide high quality evidence to determine the most appropriate kind of counselling which should be provided via the NHS Smoking Helpline and also whether or not an

  15. Post-operative telephone review is cost-effective and acceptable to patients.

    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.

    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.

    2012-07-01

    Full Text Available Abstract Background Many epidemiological and public health surveys report increasing difficulty obtaining high participation rates. We conducted a pilot follow-up study to determine whether a mailed or telephone survey would better facilitate data collection in a subset of respondents to an earlier telephone survey conducted as part of the National Birth Defects Prevention Study. Methods We randomly assigned 392 eligible mothers to receive a self-administered, mailed questionnaire (MQ or a computer-assisted telephone interview (CATI using similar recruitment protocols. If mothers gave permission to contact the fathers, fathers were recruited to complete the same instrument (MQ or CATI as mothers. Results Mothers contacted for the MQ, within all demographic strata examined, were more likely to participate than those contacted for the CATI (86.6% vs. 70.6%. The median response time for mothers completing the MQ was 17 days, compared to 29 days for mothers completing the CATI. Mothers completing the MQ also required fewer reminder calls or letters to finish participation versus those assigned to the CATI (median 3 versus 6, though they were less likely to give permission to contact the father (75.0% vs. 85.8%. Fathers contacted for the MQ, however, had higher participation compared to fathers contacted for the CATI (85.2% vs. 54.5%. Fathers recruited to the MQ also had a shorter response time (median 17 days and required fewer reminder calls and letters (median 3 reminders than those completing the CATI (medians 28 days and 6 reminders. Conclusions We concluded that offering a MQ substantially improved participation rates and reduced recruitment effort compared to a CATI in this study. While a CATI has the advantage of being able to clarify answers to complex questions or eligibility requirements, our experience suggests that a MQ might be a good survey option for some studies.

  12. The impact of using computer decision-support software in primary care nurse-led telephone triage: interactional dilemmas and conversational consequences.

    2015-02-01

    Telephone triage represents one strategy to manage demand for face-to-face GP appointments in primary care. Although computer decision-support software (CDSS) is increasingly used by nurses to triage patients, little is understood about how interaction is organized in this setting. Specifically any interactional dilemmas this computer-mediated setting invokes; and how these may be consequential for communication with patients. Using conversation analytic methods we undertook a multi-modal analysis of 22 audio-recorded telephone triage nurse-caller interactions from one GP practice in England, including 10 video-recordings of nurses' use of CDSS during triage. We draw on Goffman's theoretical notion of participation frameworks to make sense of these interactions, presenting 'telling cases' of interactional dilemmas nurses faced in meeting patient's needs and accurately documenting the patient's condition within the CDSS. Our findings highlight troubles in the 'interactional workability' of telephone triage exposing difficulties faced in aligning the proximal and wider distal context that structures CDSS-mediated interactions. Patients present with diverse symptoms, understanding of triage consultations, and communication skills which nurses need to negotiate turn-by-turn with CDSS requirements. Nurses therefore need to have sophisticated communication, technological and clinical skills to ensure patients' presenting problems are accurately captured within the CDSS to determine safe triage outcomes. Dilemmas around how nurses manage and record information, and the issues of professional accountability that may ensue, raise questions about the impact of CDSS and its use in supporting nurses to deliver safe and effective patient care.

MSCs represent a population of tissue-resident non-hematopoietic adult progenitor cells which home into injured tissues increase the proliferative potential of broncho-alveolar stem cells and restore lung epithelium. MSCs have been shown to be immune-modulatory and anti-inflammatory mediated via cell-cell contacts as well as soluble factors. We discuss the functional profile of MSCs and their potential use for adjunct cellular therapy of multi-drug resistant TB, with the aim of limiting tissue damage, and to convert unproductive inflammatory responses into effective anti-pathogen directed immune responses. Adjunct cellular therapy could potentially offer salvage therapy options for patients with drug-resistant TB, increase clinically relevant anti-M.tuberculosis directed immune responses and possibly shorten the duration of anti-TB therapy.

    The Notre Dame group has developed a new paradigm for ultra-dense and ultra-fast information processing in nanoelectronic systems. These Quantum Cellular Automata (QCA's) are the first concrete proposal for a technology based on arrays of coupled quantum dots. The basic building block of these cellular arrays is the Notre Dame Logic Cell, as it has been called in the literature. The phenomenon of Coulomb exclusion, which is a synergistic interplay of quantum confinement and Coulomb interaction, leads to a bistable behavior of each cell which makes possible their use in large-scale cellular arrays. The physical interaction between neighboring cells has been exploited to implement logic functions. New functionality may be achieved in this fashion, and the Notre Dame group invented a versatile majority logic gate. In a series of papers, the feasibility of QCA wires, wire crossing, inverters, and Boolean logic gates was demonstrated. A major finding is that all logic functions may be integrated in a hierarchial fashion which allows the design of complicated QCA structures. The most complicated system which was simulated to date is a one-bit full adder consisting of some 200 cells. In addition to exploring these new concepts, efforts are under way to physically realize such structures both in semiconductor and metal systems. Extensive modeling work of semiconductor quantum dot structures has helped identify optimum design parameters for QCA experimental implementations.

    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

    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. PMID:21424189

    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.

    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.

  13. Assessment of real exposure to GSM mobile telephones using the SYRPOM

    International Nuclear Information System (INIS)

    A mobile telephone user's exposure to the radio-frequency electromagnetic field depends heavily on the power their telephone radiates, which can vary widely according to requests from the base station. This study presents the design and development of a system called System for Radiated Power Measurement (SYRPOM), which measures the power radiated by a mobile telephone. This study also describes the tests carried out on the system itself and gives the results of two measuring campaigns it has been possible to perform in this way. The first such campaign consisted of assessing the mean power received by a typical mobile telephone user carrying out various activities. The second campaign was aimed at (1) comparing the mean radiated power when stationary and when moving and (2) assessing and contrasting different models of handsets in terms of the mean radiated power. The SYRPOM has proved to be a flexible, easy-to-use high-performance and innovative tool for carrying out this kind of studies. (authors)

  1. Radio cellular phones and health: Up-to-date research on human health

    International Nuclear Information System (INIS)

    Cellular telephones emit a radiofrequency electromagnetic field, part of which is absorbed in the user's head. Many studies have been conducted to look for their possible health hazard to human, at the experimental, epidemiological or clinical level. After a short recall on dosimetry, the author describes the state-of-the art about harmful and irreversible effects, up to now not confirmed, and about some benign symptoms which look absolutely actual. A causal relationship of the electromagnetic field on these benign symptoms is however not proven; other, studies are running to evaluate their possible long-term consequences. Interferences with cardiac pacemakers can easily be avoided by holding the telephone handset farther than 10 cm. (author)

    We measured the time taken by students to respond to individual Force Concept Inventory (FCI) questions. We examine response time differences between correct and incorrect answers, both before and after instruction. We also determine the relation between response time and expressed confidence. Our data reveal three results of interest. First, response times are longer for incorrect answers than for correct ones, indicating that distractors are not automatic choices. Second, response times increase after instruction for both correct and incorrect answers, supporting the notion that instruction changes students' approach to conceptual questions. Third, response times are inversely related to students' expressed confidence; the lower their confidence, the longer it takes to respond.

  7. Cellular mechanics and motility

    Science.gov (United States)

    Hénon, Sylvie; Sykes, Cécile

    2015-10-01

    The term motility defines the movement of a living organism. One widely known example is the motility of sperm cells, or the one of flagellar bacteria. The propulsive element of such organisms is a cilium(or flagellum) that beats. Although cells in our tissues do not have a flagellum in general, they are still able to move, as we will discover in this chapter. In fact, in both cases of movement, with or without a flagellum, cell motility is due to a dynamic re-arrangement of polymers inside the cell. Let us first have a closer look at the propulsion mechanism in the case of a flagellum or a cilium, which is the best known, but also the simplest, and which will help us to define the hydrodynamic general conditions of cell movement. A flagellum is sustained by cellular polymers arranged in semi-flexible bundles and flagellar beating generates cell displacement. These polymers or filaments are part of the cellular skeleton, or "cytoskeleton", which is, in this case, external to the cellular main body of the organism. In fact, bacteria move in a hydrodynamic regime in which viscosity dominates over inertia. The system is thus in a hydrodynamic regime of low Reynolds number (Box 5.1), which is nearly exclusively the case in all cell movements. Bacteria and their propulsion mode by flagella beating are our unicellular ancestors 3.5 billion years ago. Since then, we have evolved to form pluricellular organisms. However, to keep the ability of displacement, to heal our wounds for example, our cells lost their flagellum, since it was not optimal in a dense cell environment: cells are too close to each other to leave enough space for the flagella to accomplish propulsion. The cytoskeleton thus developed inside the cell body to ensure cell shape changes and movement, and also mechanical strength within a tissue. The cytoskeleton of our cells, like the polymers or filaments that sustain the flagellum, is also composed of semi-flexible filaments arranged in bundles, and also in

    Scuffham Paul A

    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.

  10. Telephone information-memory-concentration test used in evaluating cognitive function of patients with nasopharyngeal carcinoma after radiotherapy

    International Nuclear Information System (INIS)

    Objective: To investigate the telephone information-memory-concentration test (TIMCT) in evaluating the cognitive function of patients with nasopharyngeal carcinoma (NPC) after radiotherapy. Methods: The cognitive function were evaluated by TIMCT and mini mental state examination (MMSE) in 2 weeks for 30 normal persons and 90 NPC patients. And the 90 NPC patients were divided into the 3 months, 2 years and 5 years after radiotherapy groups. All patients were carried out firstly face to face interview and telephone interview 1 time after 2 weeks. Results: The correlation coefficient of all groups between TIMCT(telephone) and TIMCT (face to face) were bigger (R=0.850) when MMSE wasn't control variable. And the correlation coefficients between TIMCT (telephone) and TIMCT (face to face) were lower (R=0.366) when MMSE was control variable. As for examining time was classification factor, TIMCT (telephone) and TIMCT (face to face) were analyzed by partial correlation analysis. Only normal group was correlated with group of 3 months after radiotherapy and group of 2 years after radiotherapy wasn't correlated with group of 5 years after radiotherapy (R=0.447,0.970,0.200 and 0.062). In addition, the difference plot of TIMCT(telephone) and TIMCT (face to face) indicated that telephone was consistent with face to face interview (MMSE≥28). Both telephone and face to face interview reflected the cognitive function downtrend of research objects. Conclusions: TIMCT (telephone), TIMCT(face to face) and MMSE (face to face) can reflect cognitive function downterend of patients with NPC after radiotherapy. But TIMCT(telephone) used in clinical screening cognitive function impairment of patients with NPC after radiotherapy should be improved further. (authors)

    Bloch, A

    1989-12-15

    In recent years there has been increasing concern and involvement of Israeli adolescents with dieting. An increase in the incidence of obesity has been emphasized by the mass media. This has been marked by an increase in the number of questions on dieting sent anonymously by 12 to 14 year-olds to a column in a popular youth magazine about adolescent sexuality. These letters include requests for diets to prevent obesity in general and fatness of certain parts of the body in particular, such as the thighs or buttocks; questions as to side-effects of diets already started, particularly amenorrhea; and questions about the onset of bulimia and anorexia nervosa, expressing fear of the consequences. This study gives examples of the questions and the answers, and indicates the professions of those to whom the applicants were referred for further diagnosis and treatment. Newer techniques of health education with regard to adolescent dieting are urgently needed so that the health staff can promote insight and indicate the need for treatment at as early a stage as possible. The use of mass media in a suitable manner is critical, given the increase in diet-advertising. PMID:2620891

  16. 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.

    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

    Full Text Available BACKGROUND: Given escalating rates of chronic disease, broad-reach and cost-effective interventions to increase physical activity and improve dietary intake are needed. The cost-effectiveness of a Telephone Counselling intervention to improve physical activity and diet, targeting adults with established chronic diseases in a low socio-economic area of a major Australian city was examined. METHODOLOGY/PRINCIPAL FINDINGS: A cost-effectiveness modelling study using data collected between February 2005 and November 2007 from a cluster-randomised trial that compared Telephone Counselling with a "Usual Care" (brief intervention alternative. Economic outcomes were assessed using a state-transition Markov model, which predicted the progress of participants through five health states relating to physical activity and dietary improvement, for ten years after recruitment. The costs and health benefits of Telephone Counselling, Usual Care and an existing practice (Real Control group were compared. Telephone Counselling compared to Usual Care was not cost-effective ($78,489 per quality adjusted life year gained. However, the Usual Care group did not represent existing practice and is not a useful comparator for decision making. Comparing Telephone Counselling outcomes to existing practice (Real Control, the intervention was found to be cost-effective ($29,375 per quality adjusted life year gained. Usual Care (brief intervention compared to existing practice (Real Control was also cost-effective ($12,153 per quality adjusted life year gained. CONCLUSIONS/SIGNIFICANCE: This modelling study shows that a decision to adopt a Telephone Counselling program over existing practice (Real Control is likely to be cost-effective. Choosing the 'Usual Care' brief intervention over existing practice (Real Control shows a lower cost per quality adjusted life year, but the lack of supporting evidence for efficacy or sustainability is an important consideration for decision

    Harper, Jason C.

    The generation of new three-dimensional (3D) matrices that enable integration of biomolecular components and whole cells into device architectures, without adversely altering their morphology or activity, continues to be an expanding and challenging field of research. This research is driven by the promise that encapsulated biomolecules and cells can significantly impact areas as diverse as biocatalysis, controlled delivery of therapeutics, environmental and industrial process monitoring, early warning of warfare agents, bioelectronics, photonics, smart prosthetics, advanced physiological sensors, portable medical diagnostic devices, and tissue/organ replacement. This work focuses on the development of a fundamental understanding of the biochemical and nanomaterial mechanisms that govern the cell directed assembly and integration process. It was shown that this integration process relies on the ability of cells to actively develop a pH gradient in response to evaporation induced osmotic stress, which catalyzes silica condensation within a thin 3D volume surrounding the cells, creating a functional bio/nano interface. The mechanism responsible for introducing functional foreign membrane-bound proteins via proteoliposome addition to the silica-lipid-cell matrix was also determined. Utilizing this new understanding, 3D cellular immobilization capabilities were extended using sol-gel matrices endowed with glycerol, trehalose, and media components. The effects of these additives, and the metabolic phase of encapsulated S. cerivisiase cells, on long-term viability and the rate of inducible gene expression was studied. This enabled the entrapment of cells within a novel microfluidic platform capable of simultaneous colorimetric, fluorescent, and electrochemical detection of a single analyte, significantly improving confidence in the biosensor output. As a complementary approach, multiphoton protein lithography was utilized to engineer 3D protein matrices in which to

    Toxicology is a vast subject. Animals are exposed to numerous drugs, household products, plants, chemicals, pesticides and venomous animals. In addition to the individual toxicity of the various potential poisons, there is also the question of individual response and, more importantly, of species differences in toxicity. This review serves to address some of the common questions asked when dealing with animals with possible poisoning, providing evidence where available. The role of emetics, activated charcoal and lipid infusion in the management of poisoning in animals, the toxic dose of chocolate, grapes and dried fruit in dogs, the use of antidotes in paracetamol poisoning, timing of antidotal therapy in ethylene glycol toxicosis and whether lilies are toxic to dogs are discussed.

    2011-01-01

    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....

  4. Modeling and cellular studies

    International Nuclear Information System (INIS)

    Testing the applicability of mathematical models with carefully designed experiments is a powerful tool in the investigations of the effects of ionizing radiation on cells. The modeling and cellular studies complement each other, for modeling provides guidance for designing critical experiments which must provide definitive results, while the experiments themselves provide new input to the model. Based on previous experimental results the model for the accumulation of damage in Chlamydomonas reinhardi has been extended to include various multiple two-event combinations. Split dose survival experiments have shown that models tested to date predict most but not all the observed behavior. Stationary-phase mammalian cells, required for tests of other aspects of the model, have been shown to be at different points in the cell cycle depending on how they were forced to stop proliferating. These cultures also demonstrate different capacities for repair of sublethal radiation damage

    Although filoviral infections are still occurring in different parts of the world, there are no effective preventive or treatment strategies currently available against them. Not only do filoviruses cause a deadly infection, but they also have the potential of being used as biological weapons. This makes it imperative to comprehensively study these viruses in order to devise effective strategies to prevent the occurrence of these infections. Entry is the foremost step in the filoviral replication cycle and different studies have reported the involvement of a myriad of cellular factors including plasma membrane components, cytoskeletal proteins, endosomal components, and cytosolic factors in this process. Signaling molecules such as the TAM family of receptor tyrosine kinases comprising of Tyro3, Axl, and Mer have also been implicated as putative entry factors. Additionally, filoviruses are suggested to bind to a common receptor and recent studies have proposed T-cell immunoglobulin and mucin domain 1 (TIM-1) and Niemann-Pick C1 (NPC1) as potential receptor candidates. This paper summarizes the existing literature on filoviral entry with a special focus on cellular factors involved in this process and also highlights some fundamental questions. Future research aimed at answering these questions could be very useful in designing novel antiviral therapeutics. PMID:23365575

    Of interest to the communications industry are the amplitude, waveshape, duration and frequency of lightning-originated voltage surges and transients on the communications network, including the distribution system and AC power supply circuits. The cloud-to-ground lightning discharge and its characteristics are thought to be most meaningful. Of specific interest are peak current, waveshape, number of flashes, strokes per flash, and zone of influence. Accurate and meaningful lightning data at the local level (telephone district office) is necessary for a decision on the appropriate protection level. In addition to lightning, the protection engineer must consider other factors such as: AC induction, switching surges, ground potential rise, soil resistivity, bonding and grounding techniques, shielding and isolation, and exposure of the telephone loop.

  10. Emotion Analysis of Telephone Complaints from Customer Based on Affective Computing

    2015-01-01

    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.

    1987-09-01

    An estimated 8 to 10 million American children younger than 18 years of age are in self-care before or after school. Telephone call-in services to provide adult contact for these children when telephone contact with their parents is impossible or not feasible have been developed in more than 100 cities throughout the country. This study describes 2082 calls received by Tucson's KIDLINE and 2208 calls received by Baltimore's KIDSLINE. The mean age of the callers was 9.7 years, with twice as many girls as boys calling. Loneliness or boredom accounted for 68% of the calls, with fewer calls for help with homework (8%), interpersonal problems (6%), medical problems (3%), and fears (2%). Medical calls were mostly for minor infectious illness; there were no calls for life-threatening emergencies. We discuss the possible implications for pediatric practice. PMID:3618572

    Recommendation E.123 defines a standard way to write telephone numbers, e-mail addresses, and web addresses. It recommends the following formats (when dialing the area code is optional for local calling): Telephone number: National notation (042) 123 4567 International notation +31 (0)42 123 4567 E-mail address: name@provider.com Internet address / URL: www.company.com It also recommends that a hypen (-), space ( ), or period (.) can be used to visually separate groups of numbers. The parentheses are used to indicate digits that are sometimes not dialed. a slash (/) is used to indicate alternate numbers. This information is important if you want to make sure people know how to dail a phone number in a specific country.

    Evans, R L; Halar, E M; Smith, K M

    1985-10-01

    Physical disability alters a person's lifestyle and can be detrimental in its effects on mood and activity. We describe a counseling program for severely disabled persons who participated in cognitive therapy by telephone. Therapy involved solving problems related to personal dissatisfaction, loneliness, or depression. The treated group reported significantly less loneliness after treatment and were observed by their families to demonstrate more social role skills than the control group. High goal attainment reported by the treated groups was significantly correlated with decreased loneliness, positive changes in social role skills, and family expectations. Treating affective problems with scheduled telephone contact should be further evaluated because of the observed effectiveness and potential for reaching homebound clientele. PMID:2932085

    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.

    In a telephone link, the voice timbre is impaired by spectral distortions generated by the analog parts of the link. Our purpose is to restore a timbre as close as possible to that of the original voice of the speaker, using a blind equalizer centralized in the network, which compensates for the spectral distortions. We propose a spectral equalization algorithm, which consists in matching the long-term spectrum of the processed signal to a reference spectrum within a limited frequency bandwid...

    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.

  20. God in Question: Questioning as a Prerequisite for Theology

    Directory of Open Access Journals (Sweden)

    Martin Kočí

    2014-10-01

    Full Text Available There are questions that are so important that it is a pity to spoil them with answers. No doubt, the question of God is one of them. Contrary to many presuppositions, theology is not capable of providing us with the final answers in this respect. On the contrary, theology professed as fides quaerens intellectum is an ongoing struggle with questions. Modernity interrupted this paradigm of theological questioning. Theology was withdrawn from the realm of understanding and shifted to the realm of explanation. Modernity brought the univocalization of God. Nonetheless, the attempts to tackle the question of God lead to hegemonic narratives about God. Such narratives are rightly criticized in a postmodern context for their totalizing pretensions. The problem of postmodern criticism is its one-sided emphasis on the apophatic dimension of theological discourse. I propose that theology can go a step further beyond postmodernity. In order to do so, I deal with the Czech philosopher Jan Patočka, who provides an opportunity to rethink God from the perspective of questioning in a new way. Patočka’s insistence on problematicity is the main reading key of his work. In this line of though, I interpret Patočka’s student Tomáš Halík and his thesis about the necessity to take the metaphor of an unknown God into account. I argue that theology must avoid the temptation to remove God from the question and make a well-known God of him. The time has come for theologians to turn their answers back into questions and dwell with them. Bůh jako otázka: Tázání jako předpoklad teologie Některé otázky jsou tak důležité, že je škoda kazit je odpověďmi. Není pochyb, že otázka po Bohu je jednou z nich. Navzdory mnoha předpokladům, ani teologie není schopna poskytnout v tomto ohledu konečné odpovědi. Teologie pojatá jako fides quaerens intellectum je nepřetržitý nekončící zápas s otázkami. Moderna narušila toto paradigma teologick

    2011-01-01

    Cellular senescence was historically discovered as a form of cellular ageing of in vitro cultured cells. It has been under the spotlight following the evidence of oncogene-induced senescence in vivo and its role as a potent tumour suppressor mechanism. Presently, a PubMed search using keywords ‘cellular senescence and cancer’ reveals 8398 number of references (by April 2011) showing that while our knowledge of senescence keeps expanding, the complexity of the phenomenon keeps us – researchers...

  6. SIX QUESTIONS IN TEACHING LISTENING

    2004-01-01

    This paper addresses problems common in the listening classes, namely, lack of motivation, orientation and sense of achievement and the presence of pressure, fear and frustration. The author examines different factors in the teaching of listening and poses 6 questions that might help teachers to reflect on their teaching. The conclusion is that the aim of listening class is to develop rather than test listening strategies and skills; that students need to be provided with communicative tasks before and while listening; that materials should be realistic, varied and graded ; that listening should be integrated with other skills development; and finally, that learner autonomy provides the ultimate solution to listening problems.

  10. Biology Question Generation from a Semantic Network

    Science.gov (United States)

    Zhang, Lishan

    Science instructors need questions for use in exams, homework assignments, class discussions, reviews, and other instructional activities. Textbooks never have enough questions, so instructors must find them from other sources or generate their own questions. In order to supply instructors with biology questions, a semantic network approach was developed for generating open response biology questions. The generated questions were compared to professional authorized questions. To boost students' learning experience, adaptive selection was built on the generated questions. Bayesian Knowledge Tracing was used as embedded assessment of the student's current competence so that a suitable question could be selected based on the student's previous performance. A between-subjects experiment with 42 participants was performed, where half of the participants studied with adaptive selected questions and the rest studied with mal-adaptive order of questions. Both groups significantly improved their test scores, and the participants in adaptive group registered larger learning gains than participants in the control group. To explore the possibility of generating rich instructional feedback for machine-generated questions, a question-paragraph mapping task was identified. Given a set of questions and a list of paragraphs for a textbook, the goal of the task was to map the related paragraphs to each question. An algorithm was developed whose performance was comparable to human annotators. A multiple-choice question with high quality distractors (incorrect answers) can be pedagogically valuable as well as being much easier to grade than open-response questions. Thus, an algorithm was developed to generate good distractors for multiple-choice questions. The machine-generated multiple-choice questions were compared to human-generated questions in terms of three measures: question difficulty, question discrimination and distractor usefulness. By recruiting 200 participants from

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

    Duclos, Guillaume; Erlenkaemper, Christoph; Garcia, Simon; Yevick, Hannah; Joanny, Jean-François; Silberzan, Pascal; Biology inspired physics at mesoscales Team; Physical approach of biological problems Team

    We study the emergence of a nematic order in a two-dimensional tissue of apolar elongated fibroblast cells. Initially, these cells are very motile and the monolayer is characterized by giant density fluctuations, a signature of far-from-equilibrium systems. As the cell density increases because of proliferation, the cells align with each other forming large perfectly oriented domains while the cellular movements slow down and eventually freeze. Therefore topological defects characteristic of nematic phases remain trapped at long times, preventing the development of infinite domains. By analogy with classical non-active nematics, we have investigated the role of boundaries and we have shown that cells confined in stripes of width smaller than typically 500 µm are perfectly aligned in the stripe direction. Experiments performed in cross-shaped patterns show that both the number of cells and the degree of alignment impact the final orientation.

    International migrations have growing implications for both countries of destination. In the latter, the presence of foreigners and of members of their families today creates problems of integration, causes argument, and brings mounting xenophobia. Paralleling political, economic, and social measures taken by public authorities to respond to these difficulties, education needs to assist in diffusing the resulting social tensions by preparing the minds of learners and helping to develop new attitudes. In particular, when educational programs address questions of international migration, these should be treated in the framework of historical evolution in order that their real significance and their true temporal and spatial dimensions become apparent. It is also important that the growing interdependence between countries should be made plain, that national history should be placed in its international context, and that the true consequences of these developments should be made clear. In this context, learners need to be acquainted with Human Rights, thereby stressing universal moral values and the role of the individual. Lastly, questions relating to international migration are usually presented in the media in a selective and partial manner, and the young people who take in this information often accept the hasty judgments which are made of situations as proven facts. This is why all teaching about international migration needs to be considered or reconsidered in light of the complementary or competing actions of the media. (author's modified) PMID:12286405

  15. Answering Key Fuel Cycle Questions

    International Nuclear Information System (INIS)

    Given the range of fuel cycle goals and criteria, and the wide range of fuel cycle options, how can the set of options eventually be narrowed in a transparent and justifiable fashion? It is impractical to develop all options. We suggest an approach that starts by considering a range of goals for the Advanced Fuel Cycle Initiative (AFCI) and then posits seven questions, such as whether Cs and Sr isotopes should be separated from spent fuel and, if so, what should be done with them. For each question, we consider which of the goals may be relevant to eventually providing answers. The AFCI program has both ''outcome'' and ''process'' goals because it must address both waste already accumulating as well as completing the fuel cycle in connection with advanced nuclear power plant concepts. The outcome objectives are waste geologic repository capacity and cost, energy security and sustainability, proliferation resistance, fuel cycle economics, and safety. The process objectives are rea diness to proceed and adaptability and robustness in the face of uncertainties

    2008-07-01

    The scope of clinical low vision services and access to comprehensive eye care through U.S. schools for the blind and visually impaired is not well known. Advances in medicine and educational trends toward inclusion have resulted in higher numbers of visually impaired children with additional cognitive, motor, and developmental impairments enrolled in U.S. schools for the blind and visually impaired. The availability and frequency of eye care and vision education services for individuals with visual and multiple impairments at schools for the blind is explored in this report using data collected in a 24-item telephone survey from 35 of 42 identified U.S. schools for the blind. The results indicate that 54% of the contacted schools (19) offer clinical eye examinations. All of these schools provide eye care to the 6 to 21 age group, yet only 10 schools make this service available to children from birth to 3 years of age. In addition, two thirds of these schools discontinue eye care when the students graduate or transition to adult service agencies. The majority (94.7%) of eye care is provided by optometrists or a combination of optometry and ophthalmology, and 42.1% of these schools have an affiliation with an optometric institution. When there is a collaborative agreement, clinical services for students are available more frequently. The authors find that questions emerge regarding access to care, identification of appropriate models of care, and training of educational/medical/optometric personnel to meet the needs of a very complex patient population.

    Michelle H M M T van Velthoven

    Full Text Available BACKGROUND: Low cost, effective interventions are needed to deal with the major global burden of HIV/AIDS. Telephone consultation offers the potential to improve health of people living with HIV/AIDS cost-effectively and to reduce the burden on affected people and health systems. The aim of this systematic review was to assess the effectiveness of telephone consultation for HIV/AIDS care. METHODS: We undertook a comprehensive search of peer-reviewed and grey literature. Two authors independently screened citations, extracted data and assessed the quality of randomized controlled trials which compared telephone interventions with control groups for HIV/AIDS care. Telephone interventions were voice calls with landlines or mobile phones. We present a narrative overview of the results as the obtained trials were highly heterogeneous in design and therefore the data could not be pooled for statistical analysis. RESULTS: The search yielded 3321 citations. Of these, nine studies involving 1162 participants met the inclusion criteria. The telephone was used for giving HIV test results (one trial and for delivering behavioural interventions aimed at improving mental health (four trials, reducing sexual transmission risk (one trial, improving medication adherence (two trials and smoking cessation (one trial. Limited effectiveness of the intervention was found in the trial giving HIV test results, in one trial supporting medication adherence and in one trial for smoking cessation by telephone. CONCLUSIONS: We found some evidence of the benefits of interventions delivered by telephone for the health of people living with HIV or at risk of HIV. However, only limited conclusions can be drawn as we only found nine studies for five different interventions and they mainly took place in the United States. Nevertheless, given the high penetration of low-cost mobile phones in countries with high HIV endemicity, more evidence is needed on how telephone consultation

  10. Statistical questions in experimental evolution

    International Nuclear Information System (INIS)

    Recent advances in the mathematical analysis of models describing evolutionary dynamics are rapidly increasing our ability to make precise quantitative predictions. These advances have created a growing need for corresponding improvements in our ability to observe evolutionary dynamics in laboratory evolution experiments. High-throughput experimental methods are particularly crucial, in order to maintain many replicate populations and measure statistical differences in evolutionary outcomes at both phenotypic and genomic levels. In this paper, I describe recent technical developments which have greatly increased the throughput of laboratory evolution experiments, and outline a few promising directions for further improvements. I then highlight a few ways in which these new experimental methods can help to answer simple statistical questions about evolutionary dynamics, and potentially guide future theoretical work

    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,...

    1991-10-01

    The tool presented here is useful in analyzing the constraints and capabilities of a health care telephone service. It also provides a systematic method for assessing systems problems. As part of our analysis, we recommended that the manager implement the following steps. First, the manager determines whether the driving force on the unit is continuity of care by an individual provider or consistency of response. This focus directly affects how the unit's telephone service can be best organized (i.e., decentralized or centralized) and clarifies the factors most needed for success. For example, to function effectively and efficiently, a centralized phone service needs strong provider-endorsed protocols. Second, the manager should carefully examine neutral constraint factors to determine methods to transform these constraints into capabilities, such as planning for extra staff or office hours (or both) during influenza season. Planning for extra hours or staff depends largely on whether budget and resource planning is done in advance and whether value is placed on customer access and satisfaction during peak demand periods. The manager must next determine whether the service delivery format (centralized or decentralized) is consistent with the force field analysis findings. If the findings are not consistent, can the analysis present a compelling argument for using the opposite approach? Finally, the manager must create a plan of action for minimizing the constraints revealed and maximizing existing capabilities to achieve the overall goal of excellent phone service. The process of analysis and creating a plan of action is an excellent opportunity to involve staff, providers, and administrators in efforts to achieve better health care telephone service for all customers.

    2012-01-01

    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 Introduction:Postpartum depression is a common disorder. Systematic reviews emphasized the need to conduct more trials about interventions to prevent postpartum depression. The aim of this study was to determine the effect of postpartum telephone support on maternal depression. Methods:366 postpartum women with no history of known depression were randomly assigned into control (244 subjects and intervention (122 subjects groups. The control group received only routine postpartum care. In the intervention group, telephone support was provided twice in the first week and once a week during the second to sixth week of postpartum by a trained midwife in addition to the routine care. In order to meet their unpredicted needs, the mothers could contact the consultant 24 hours a day. Postpartum depression was assessed using the self-administered Edinburgh Depression Scale at 60 to 65 days of postpartum. Mothers with scores of 13 and above were considered to have depression. Logistic regression and Student’s t-test were used for the data analysis. Results:There was no significant difference regarding frequency of depression between the intervention and control groups (29.9% vs. 31.6%; Odds ratio 0.91, 95% CI 0.56 to 1.49. Mean of depression score was not significantly different between the groups [9.2 (6.1 vs. 10.4 (5.8; mean difference -1.19, 95%CI -2.5 to 0.13]. Conclusion:This study did not provide evidence to show that telephone support of a midwife during postpartum period have a preventive effect on postpartum depression.

    Dyspnoea is the most common symptom associated with poor quality of life in patients affected by Chronic Obstructive Pulmonary Disease (COPD). While COPD severity is commonly staged by lung function, the Medical Research Council (MRC) dyspnoea scale has been proposed as a more clinically meaningful method of quantifying disease severity in COPD. We wished to assess whether this scale might also be useful during telephone surveys as a simple surrogate marker of perceived health status in elderly patients with COPD. We conducted a comprehensive health status assessment by telephone survey of 200 elderly patients who had a physician diagnosis of COPD. The telephone survey contained 71 items and explored such domains as educational level, financial status, living arrangements and social contacts, co-morbid illness, and the severity and the impact of COPD on health status. Patients were categorized according to the reported MRC score: mild dyspnoea (MRC scale of 1), moderate dyspnoea (MRC scale of 2 and 3), or severe dyspnoea (MRC of 4 and 5). Deterioration in most of the recorded indicators of health status correlated with an increasingly severe MRC score. This was most evident for instrumental activities of daily living (IADL), perceived health and emotional status, pain-related limitations, limitations in social life, hospital admissions in preceding year and prevalence of most co-morbidities. The MRC dyspnoea scale is a reliable index of disease severity and health status in elderly COPD patients which should prove useful for remote monitoring of COPD and for rating health status for epidemiological purposes.

    Contributions by human factors to all phases of the product development cycle are illustrated by work done on business telephone systems. The work includes surveys of customer needs, laboratory tests of alternative physical designs and control procedures, development of efficient and effective instructional methods, field studies of delivery systems, and field evaluations of the final product. It is also demonstrated that data from applied studies can lead to general principles which are useful in other situations. Finally, suggestions are given about effective timing and organisational structure for human factors work. PMID:15676489

    The need to use mobile telephones and PDA’s as electronic-payment devices became stronger as the global mobile penetration rate reached 17 percent. However, due to the technological limitations and security considerations, the well established jargon of electronic-payment could not be employed in mobile-payment (m-payment), specifically for payment of very low amounts (e.g. micro-payment). Therefore, new technologies are needed for enabling m-payment. In this paper, we investigate the s...

    Why have we tried so hard to find the Higgs particle? How does the Higgs mechanism work? What is the difference in physics between strong evidence and a discovery? Why do physicists speak in terms of "sigmas"? Find out here!   Why have we tried so hard to find the Higgs particle? Because it could be the answer to the question: how does Nature decide whether or not to assign mass to particles? All the fundamental particles making up matter – the electron, the quarks, etc. – have masses. Moreover, quantum physics requires that forces are also carried by particles. The W and Z particles that carry the weak force responsible for radioactivity must also have masses, whereas the photon, the carrier of the electromagnetic force, has no mass at all. This is the root of the “Higgs problem”: how to give masses to the fundamental particles and break the symmetry between the massive W and Z and the massless photon? Just assigning masses by hand...

    2012-03-01

    Full Text Available “Socratic Method” is a way of teaching philosophical thinking and knowledge by asking questions which was used by antique period greek philosopher Socrates. Socrates was teaching knowledge to his followers by asking questions and the conversation between them was named “Socratic Dialogues”. In this meaning, no novel knowledge is taught to the individual but only what is formerly known is reminded and rediscovered. The form of socratic questioning which is used during the process of cognitive behavioral therapy is known as Guided Discovery. In this method it is aimed to make the client notice the piece of knowledge which he could notice but is not aware with a series of questions. Socratic method or guided discovery consists of several steps which are: Identifying the problem by listening to the client and making reflections, finding alternatives by examining and evaluating, reidentification by using the newly found information and questioning the old distorted belief and reaching to a conclusion and applying it. Question types used during these procedures are, questions for gaining information, questions revealing the meanings, questions revealing the beliefs, questions about behaviours during the similar past experiences, analyse questions and analytic synthesis questions. In order to make the patient feel understood it is important to be empathetic and summarising the problem during the interview. In this text, steps of Socratic Questioning-Guided Discovery will be reviewed with sample dialogues after each step

  11. Origami interleaved tube cellular materials

    International Nuclear Information System (INIS)

    A novel origami cellular material based on a deployable cellular origami structure is described. The structure is bi-directionally flat-foldable in two orthogonal (x and y) directions and is relatively stiff in the third orthogonal (z) direction. While such mechanical orthotropicity is well known in cellular materials with extruded two dimensional geometry, the interleaved tube geometry presented here consists of two orthogonal axes of interleaved tubes with high interfacial surface area and relative volume that changes with fold-state. In addition, the foldability still allows for fabrication by a flat lamination process, similar to methods used for conventional expanded two dimensional cellular materials. This article presents the geometric characteristics of the structure together with corresponding kinematic and mechanical modeling, explaining the orthotropic elastic behavior of the structure with classical dimensional scaling analysis.

This suggests the universality of chimera-like behavior from a new point of view: Already simple CA rules based on the majority rule exhibit this behavior. After a short transient, we find chimera states for arbitrary initial conditions, the...

    tAs a result of the rapid technical development in the area of modern telecommunication the public is increasingly exposed to high frequency electromagnetic fields in every day life. High frequency electromagnetic fields propagate for example from transmitter stations such as radio frequency towers and cellular base stations, or from cellular phones in use. Expert groups have argued, that these fields might have an impact on the health status of man, based on scientific suspicion about possible biological effects. Various effects have been observed as a result of the exposure to high frequency electromagnetic fields. Hints to possible effects exist at field strengths even below the recommended limit values. Today, there is no definite answer to the question whether or not such effects would cause any health risk for man. Therefore, it is common sense that efforts to increase and to better co-ordinate research activities are required. In June 2001 the Federal Office for Radiation Protection has organised a workshop with broad participation of experts in order to identify and discuss research priorities concerning the effects of electromagnetic fields from mobile telecommunication. Based on the results of this workshop a research programme was developed. The individual projects are focused on: Interaction mechanisms of high frequency fields, Effects in men and animals, Epidemiological studies, Dosimetry, Electromagnetic hypersensitivity, Risk communication.

  1. Occupational exposure to ambient electromagnetic fields of technical operational personnel working for a mobile telephone operator

    International Nuclear Information System (INIS)

    In order to investigate the exposure of operational personnel to radiofrequency electromagnetic fields when working for a mobile telephone operator, exposimeters were used to make individual records on 23 Technical Operations personnel (mobile telephone maintenance staff) and also on 22 Other Workers. The exposure densities, to which each of the 45 subjects was subjected, were quantified using 229 exposure indicators. Cluster analysis techniques were applied to the data, in an attempt to show that they would re-emerge as belonging to one of the two groups, i.e. the Technical Operational Personnel group or the Other Workers group. This exploratory investigation has shown that the cluster analysis does not reveal a sufficiently reliable emergence of the two groups, even though certain exposure indicators were significantly different for the two groups. In addition, the use of a Learning Group method does not lead to the discovery of a predictive law that could identify the Technical Operational Personnel as a sub-group within the overall group.

    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.

    Chronic or intermittent headache affects the patients' quality of life, and has direct and indirect social costs. Several chronic illnesses are already treated through telephone counseling, however there is poor evidence in literature about headache treatment via telenursing, and it is not clear which role could the nurse play in this specific field. The study was carried out at the headache centre of "G. D'Annunzio" University - Chieti, and involved 62 patients, half of them were assigned to receive specialized telenursing in addiction to the standard care bean. During the 13 weeks of follow up the headache characteristics were regularly assessed (frequency and intensity). Pain assessment was performed using the VAS, and quality of life was assessed at baseline and at the end of the follow up using the SF-12 standard V1 questionnaire. The differences between the two groups are statistically significant during the last 5 week of follow up, (8th -12th; 0.002pain. A telephone counseling given by specialized nurses can help to reduce the hospitalization rates, as well as help the patient to comply to the therapeutic plan, and increases the perceived psychophysical well being. During the three months of study, the headache symptoms statistically reduced only during the last 5 weeks of follow up. Further studies with a longer follow up are needed to better assess the long term outcomes of this approach (symptoms management and social and healthcare costs). PMID:22044548

    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.

    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.

    A language is the tool of human communication. English teaching is really not a way to input or output information-it is not an one-way transmission of information. Students must personally think, speak and write what they are taught. That is the practical features of English teaching. Questioning is one of important methods which embody this feature completely. Teachers apply asking questions to enlighten and stimulate students in order to perfect this vital importance. Students who are in middle schools are asked questions but do not give answers. Except for learners' own quality and degree of difficulty of questions, it is connected with teachers' quality of asking questions.

    A passage retrieval strategy for web-based question answering (QA) systems is proposed in our QA system. It firstly analyzes the question based on semantic patterns to obtain its syntactic and semantic information and then form initial queries. The queries are used to retrieve documents from the World Wide Web (WWW) using the Google search engine. The queries are then rewritten to form queries for passage retrieval in order to improve the precision. The relations between keywords in the question are employed in our query rewrite method. The experimental result on the question set of the TREC-2003 passage task shows that our system performs well for factoid questions.

    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.

    Cellular materials consist of interconnected struts or plates which form cells. The struts or plates are constructed from a variety of metals, polymers, ceramics and wood products. Cellular materials are often used in impact limiters for shipping containers to protect the contents from accidental impact events. These materials exhibit a variety of complex behavior when subjected to crushing loads. This research focuses on the development of continuum representations of cellular solids that can be used in the finite element analysis of shipping container accidents. A significant portion of this work is the development of a new methodology to relate localized deformations to appropriate constitutive descriptions. This methodology provides the insight needed to select constitutive descriptions for cellular solids that capture the localized deformations that are observed experimentally. Constitutive relations are developed for two different cellular materials, aluminum honeycomb and polyurethane foam. These constitutive relations are based on plasticity and continuum damage theories. Plasticity is used to describe the permanent deformation exhibited by both aluminum honeycomb and polyurethane foam. Continuum damage is needed to capture the change in elastic parameters due to cracking of the polyurethane cell wall materials. The new constitutive description of polyurethane foam is implemented in both static and dynamic finite element codes, and analytical and numerical predictions are compared with available experimental data.

    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.

    For most species, aging promotes a host of degenerative pathologies that are characterized by debilitating losses of tissue or cellular function. However, especially among vertebrates, aging also promotes hyperplastic pathologies, the most deadly of which is cancer. In contrast to the loss of function that characterizes degenerating cells and tissues, malignant (cancerous) cells must acquire new (albeit aberrant) functions that allow them to develop into a lethal tumor. This review discusses the idea that, despite seemingly opposite characteristics, the degenerative and hyperplastic pathologies of aging are at least partly linked by a common biological phenomenon: a cellular stress response known as cellular senescence. The senescence response is widely recognized as a potent tumor suppressive mechanism. However, recent evidence strengthens the idea that it also drives both degenerative and hyperplastic pathologies, most likely by promoting chronic inflammation. Thus, the senescence response may be the result of antagonistically pleiotropic gene action. PMID:23140366

    2011-01-01

    A cellular-based preemption system that uses existing cellular infrastructure to transmit preemption related data to allow safe passage of emergency vehicles through one or more intersections. A cellular unit in an emergency vehicle is used to generate position reports that are transmitted to the one or more intersections during an emergency response. Based on this position data, the one or more intersections calculate an estimated time of arrival (ETA) of the emergency vehicle, and transmit preemption commands to traffic signals at the intersections based on the calculated ETA. Additional techniques may be used for refining the position reports, ETA calculations, and the like. Such techniques include, without limitation, statistical preemption, map-matching, dead-reckoning, augmented navigation, and/or preemption optimization techniques, all of which are described in further detail in the above-referenced patent applications.

    The Center for Integrated Space Weather Modeling (CISM) holds a two-week Space Weather Summer School for introductory graduate students and space weather professionals to gain a system level understanding of the space environment and the effects of space weather. A typical day in the summer school consists of three morning lectures followed by an afternoon lab session. After the morning lectures, the participants are each asked to submit a question about the mornings topics on a question card. The lecturers then take the time to answer these questions prior to afternoon sessions. In the last 5 years over 1000 such question cards have been collected and cataloged. Despite detailed lectures by experts similar questions appear every year. We have analyzed over 150 questions related to the introductory lectures on solar physics and solar activity. Questions content was categorized using the AGU Index, and question sophistication was categorized using Bloom’s Taxonomy of Educational Objectives. Specific analysis results along with lists of questions will be presented. We hope that these results can be used to improve the lecture and classroom content and allow students to move beyond low level education objectives and ask more sophisticated questions.

  8. Speech watermarking: an approach for the forensic analysis of digital telephonic recordings.

    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. PMID:20412360

    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. PMID:26413714

    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.

  16. True random number generation from mobile telephone photo based on chaotic cryptography

    International Nuclear Information System (INIS)

    A cheap, convenient and universal TRNG based on mobile telephone photo for producing random bit sequence is proposed. To settle the problem of sequential pixels and comparability, three chaos-based approaches are applied to post-process the generated binary image. The random numbers produced by three users are tested using US NIST RNG statistical test software. The experimental results indicate that the Arnold cat map is the fastest way to generate a random bit sequence and can be accepted on general PC. The 'MASK' algorithm also performs well. Finally, comparing with the TRNG of Hu et al. [Hu Y, Liao X, Wong KW, Zhou Q. A true random number generator based on mouse movement and chaotic cryptography. Chaos, Solitons and Fractals 2007. doi: 10.1016/j.chaos.2007.10.022] which is presented by Hu et al., many merits of the proposed TRNG in this paper has been found.

    2006-03-01

    The aging of organisms is characterized by a gradual functional decline of all organ systems. Mammalian somatic cells in culture display a limited proliferative life span, at the end of which they undergo an irreversible cell cycle arrest known as replicative senescence. Whether cellular senescence contributes to organismal aging has been controversial. We investigated telomere dysfunction, a recently discovered biomarker of cellular senescence, and found that the number of senescent fibroblasts increases exponentially in the skin of aging baboons, reaching >15% of all cells in very old individuals. In addition, the same cells contain activated ataxia-telangiectasia mutated kinase and heterochromatinized nuclei, confirming their senescent status. PMID:16456035

  1. Cellular automaton for chimera states

    Science.gov (United States)

    García-Morales, Vladimir

    2016-04-01

    A minimalistic model for chimera states is presented. The model is a cellular automaton (CA) which depends on only one adjustable parameter, the range of the nonlocal coupling, and is built from elementary cellular automata and the majority (voting) rule. This suggests the universality of chimera-like behavior from a new point of view: Already simple CA rules based on the majority rule exhibit this behavior. After a short transient, we find chimera states for arbitrary initial conditions, the system spontaneously splitting into stable domains separated by static boundaries, some synchronously oscillating and the others incoherent. When the coupling range is local, nontrivial coherent structures with different periodicities are formed.
