    Full Text Available This study explores the nature of how mobile social media may potentially be sharpening the tenor of communicating online. Specifically, randomized representative Twitter data were collected for several controversial issues, and then examined to determine the extent to which mobile or web-based content tends more toward greater incivility and impoliteness. Additional analyses further model how certain dialogic features, such as explicitly mentioning other users and retweeting others’ posts, positively relate to hostility in the discourse. Building on the basis of technological affordances and user negotiation in digitally mediated environments, this study contributes to a better understanding of how individuals express themselves on mobile devices as these are rapidly becoming normalized modes for communicating with one another online.

  4. Interpreting Impoliteness: Interpreters’ Voices

    Full Text Available Interpreters in the public sector in Norway interpret in a variety of institutional encounters, and the interpreters evaluate the majority of these encounters as polite. However, some encounters are evaluated as impolite, and they pose challenges when it comes to interpreting impoliteness. This issue raises the question of whether interpreters should take a stance on their own evaluation of impoliteness and whether they should interfere in communication. In order to find out more about how interpreters cope with this challenge, in 2014 a survey was sent to all interpreters registered in the Norwegian Register of Interpreters. The survey data were analyzed within the theoretical framework of impoliteness theory using the notion of moral order as an explanatory tool in a close reading of interpreters’ answers. The analysis shows that interpreters reported using a variety of strategies for interpreting impoliteness, including omissions and downtoning. However, the interpreters also gave examples of individual strategies for coping with impoliteness, such as interrupting and postponing interpreting. These strategies border behavioral strategies and conflict with the Norwegian ethical guidelines for interpreting. In light of the ethical guidelines and actual practice, mapping and discussing different strategies used by interpreters might heighten interpreters’ and interpreter-users’ awareness of the role impoliteness can play in institutional interpreter– mediated encounters.

    Use of mobile phones has rapidly risen among adolescents despite a lack of scientific certainty on their health risks. Risk perception is an important determinant of behavior, and studies on adolescents' risk perceptions of mobile phones or base stations are very scarce. This study aims to evaluate high school students' risk perceptions on mobile phones and base stations, their trust to authorities, their opinions regarding incivility while using mobile phones and to assess associated factors. For this cross-sectional study, 2530 students were chosen with stratified cluster sampling among 20,493 high school students studying in Bornova district of Izmir, Turkey, among whom 2240 (88.5%) participated. Risk perceptions and opinions were questioned with a 5-point Likert scale for 24 statements grouped under four dimensions. The mean responses to the four dimensions were categorized as mobile phone, base station, trust to authority and incivility dimensions were 3.69 ± 0.89, 4.34 ± 0.78, 3.77 ± 0.93, 3.16 ± 0.93 and the prevalence of high risk perception was 65.1%, 86.7%, 66.2%, 39.7%, respectively. In the mobile phone dimension; students attending industrial technical high school had lower risk perceptions while female students, lower mothers' education groups and students not using mobile phones (OR = 2.82, 95% CI = 1.80-4.40) had higher risk perceptions. In the base station dimension girls had higher risk perceptions (OR = 1.68, 95% CI = 1.20-2.37). Girls and students attending industrial technical high school had significantly lower risk perception however 11-12th grade group perceived the risk higher (OR = 1.45 95% CI = 1.15-1.84) in the trust to authority dimension. For the incivility dimension, female students (OR = 1.44, 95% CI = 1.14-1.82), illiterate/only literate mothers (OR = 1.79, 95% CI = 1.04-2.75) and students not using mobile phones (OR = 2.50, 95% CI = 1.62-3.87) perceived higher risk. Understanding the effects of these determinants might aid in

  6. Exploring the effects of individual customer incivility encounters on employee incivility: the moderating roles of entity (in)civility and negative affectivity.

    Incivility between customers and employees is common in many service organizations. These encounters can have negative outcomes for employees, customers, and the organization. To date, researchers have tended to study incivility as an aggregated and accumulated phenomenon (entity perspective). In the present study, we examined incivility as it occurs during a specific service encounter (event perspective) alongside the entity perspective. Using a mixed-method multilevel field study of customer service interactions, we show that individual customer incivility encounters (i.e., events) trigger employee incivility as a function of the employee's overall accumulated impression of the (in)civility in his or her customer interactions, such that the effects are more pronounced among employees who generally perceive their customer interactions to be more versus less civil. We also find that these interactive effects occur only among employees who are lower (vs. higher) in negative affectivity. Our results show that, in order to expand the understanding of customer incivility, it is important to study the incivility encounter, the social context in which negative customer interactions occur, and individual differences.

    Full Text Available The aim of the study was to investigate workplace incivility as a social process, examining its components and relationships to both instigated incivility and negative outcomes in the form of well-being, job satisfaction, turnover intentions, and sleeping problems. The different components of incivility that were examined were experienced and witnessed incivility from coworkers as well as supervisors. In addition, the organizational factors, social support, control, and job demands, were included in the models. A total of 2871 (2058 women and 813 men employees who were connected to the Swedish Hotel and Restaurant Workers Union completed an online questionnaire. Overall, the results from structural equation modelling indicate that whereas instigated incivility to a large extent was explained by witnessing coworker incivility, negative outcomes were to a high degree explained by experienced supervisor incivility via mediation through perceived low social support, low control, and high job demands. Unexpectedly, the relationships between incivility (experienced coworker and supervisor incivility, as well as witnessed supervisor incivility and instigated incivility were moderated by perceived high control and high social support. The results highlight the importance of including different components of workplace incivility and organizational factors in future studies of the area.

    Full Text Available The main objective of this article is to outline an analysis of verbal politeness and impoliteness based on selected passages of El Quijote and Borges’ story Pierre Ménard, autor del Quijote. Through the lens of these texts, we were able to examine some of the different theories that have emerged on this topic, and, in particular, certain politeness strategies. In our discussion we consider both the rhetorical perspective (which encompasses strategies for creating persuasive discourse, and the logical perspective, basing our arguments on specific examples in the texts. The results of this analysis lead to the conclusion that verbal politeness offers a frame of reference which enables a better under­standing of the texts in question, opening up new perspectives not considered by traditional literary theory. Further, we observed that not everything that initially appeared impolite, and even offensive, actually was impolite, and vice versa.

    2015-01-01

    This study aimed to describe the meaning of the concept 'workplace incivility' and promote consistency in its application in nursing research and practice. The methodology introduced by Walker and Avant was used to analyze this concept. A total number of 50 studies that had essentially addressed the concept of incivility in employees' work environment was selected. Ambiguous intent, violation of mutual respect, low intensity and lack of physical assault were identified as the defining attributes of workplace incivility. The necessary antecedent of workplace incivility consisted of the presence of two or more people, with one or more as the source of the incivility, and another or others as its target in the workplace. Moreover, certain individual and organisational factors were the potential antecedents of workplace incivility. Possible negative outcomes for victims, witnesses, organisations, society and perpetrators of such behaviours, such as increased cost for the organisation, reduced citizenship performance, psychological distress and anxiety were identified as outcomes of workplace incivility. Results of the current concept analysis can guide nurse managers to design interventions so that the occurrence of workplace incivility can be reduced. Further studies can focus on testing the psychometric properties of the existing workplace incivility scales, especially uncivil behaviours experienced by nurses across different societies or cultures.

The first aim was to assess how common the phenomenon is and the second was to study which groups (gender, age, ethnicity, and power position are most targeted by workplace incivility and are more prone to act in an uncivil way. Additionally, the relationships between experienced and witnessed incivility and wellbeing as well as instigated incivility were investigated. An online survey was administered by SIFO (the national public opinion poll agency. The collected data consist of a stratified sample whose composition is identical to the working population in Sweden (N = 3001. The results show that almost three quarters of the respondents had been the target of coworker incivility and 52% of supervisor incivility at least one to two times in the past year. Of the respondents, 75% had witnessed coworkers and 58% witnessed a supervisor treating others in an uncivil way. Furthermore, 66% had instigated uncivil acts toward others. The results also show that female and younger employees are slightly more targeted by incivility from coworkers and younger employees and supervisors are slightly more prone to instigate incivility. Moreover, it was found that that experienced incivility was the strongest predictor of low well-being and that witnessed incivility was the strongest predictor of instigated incivility.

    ABSTRACT In recent years a growing amount of research has been conducted in the area of workplace incivility. Whereas many studies have focused on the victims and the consequences of incivility, little attention has been paid to the perpetrators and antecedents of workplace incivility. This study aims to identify possible antecedents of workplace incivility, by investigating organizational aspects as well as the possibility that being the target of incivility from co-workers and supervisors could induce incivility. A total of 512 employees (378 women and 133 men) in the school sector in a Swedish municipality completed an online questionnaire. Overall, the results of structural equation modelling analyses showed that organizational variables were related to the perpetration of incivility. A direct relationship was found between being uncivil and organizational change, job insecurity, low social support from co-workers and high job demands. However, the strongest relationship was found between experienced incivility from co-workers and instigated incivility. This could be reflecting a climate or culture of incivility in the organization, and carry implications for future practice in interventions against workplace incivility. The results indicate the importance of focusing on the perspective of the instigator to gain knowledge about the process of workplace incivility. PMID:27226677

    2012-01-01

    Academic incivility remains a problem on college campuses. Nursing research has refocused from student impropriety to aberrant faculty behaviors. Our original study using the Nursing Education Environment Survey showed that 133 of 152 student participants experienced uncivil treatment. Latent, inductive content analysis was undertaken to analyze narratives about their "worst experience" of negative faculty behavior. Four categories were identified: "In front of someone," "Talked to others about me," "Made me feel stupid," and "I felt belittled." Incivility had a profound effect on students and is problematic because it increases already significant academic pressure; it interferes with learning and safe clinical performance; it is contrary to caring, a central nursing concept; and it decreases program satisfaction and retention. Few nursing schools have civility policies for faculty behavior. Formal procedures that promote professional interaction should be crafted and implemented. Equally important is creating ways for nursing students to document incivility without fear of retaliation. Copyright © 2012 Elsevier Inc. All rights reserved.

    Emergency responders must “see” the effects of an earthquake clearly and rapidly so that they can respond effectively to the damage it has produced. Great strides have been made recently in developing methodologies that deliver rapid and accurate post-earthquake information. However, shortcomings still exist. The iShake project is an innovative use of cell phones and information technology to bridge the gap between the high quality, but sparse, ground motion instrument data that are used to help develop ShakeMap and the low quality, but large quantity, human observational data collected to construct a “Did You Feel It?” (DYFI)-based map. Rather than using people as measurement “devices” as is being done through DYFI, the iShake project is using their cell phones to measure ground motion intensity parameters and automatically deliver the data to the U.S. Geological Survey (USGS) for processing and dissemination. In this participatory sensing paradigm, quantitative shaking data from numerous cellular phones will enable the USGS to produce shaking intensity maps more accurately than presently possible. The phone sensor, however, is an imperfect device with performance variations among phones of a given model as well as between models. The sensor is the entire phone, not just the micro-machined transducer inside. A series of 1-D and 3-D shaking table tests were performed at UC San Diego and UC Berkeley, respectively, to evaluate the performance of a class of cell phones. In these tests, seven iPhones and iPod Touch devices that were mounted at different orientations were subjected to 124 earthquake ground motions to characterize their response and reliability as seismic sensors. The testing also provided insight into the seismic response of unsecured and falling instruments. The cell phones measured seismic parameters such as peak ground acceleration (PGA), peak ground velocity (PGV), peak ground displacement (PGD), and 5% damped spectral accelerations well

    Casale, Katherine R

    The purpose of this quantitative correlational study was to explore the relationship between the frequency of interfaculty incivility among nurses in academia and observed levels of resonant leadership of immediate supervisors. Despite mandates to address incivility in health care, nurse faculty report high levels of horizontal incivility among their peers. No known quantitative research has measured the relationship between nurse faculty-to-faculty incivility and resonant leadership traits of leaders. Nursing faculty from 17 universities (n = 260) were emailed an anonymous link to answer survey questions about horizontal peer incivility and leaders' management styles. There was a significant inverse relationship (Pearson's r, -.560) between the frequency of experienced faculty-to-faculty incivility and the level of observed resonant leadership behaviors of participants' immediate supervisors. Resonant supervisory behaviors inversely correlated with nurse faculty peer incivility, with potential to impact satisfaction, recruitment, and retention.

    Although incivility is a common interpersonal mistreatment and associated with poor mental health, there are few studies about it in Asian countries. The aim of this study was to develop the Japanese version of the modified Work Incivility Scale (J-MWIS), investigate its reliability and validity, and reveal the prevalence of incivility among Japanese employees in comparison with data on Canadian employees. A total of 2,191 Japanese and 1,071 Canadian employees were surveyed, using either the J-MWIS or MWIS. Japanese employees additionally answered questions on civility, worksite social support, workplace bullying, psychological distress, intention to leave, and work engagement to investigate construct validity. At least one form of workplace incivility was experienced by both Japanese (52.3%) and Canadian (86.0%) employees in the previous month. Internal consistency reliability of the J-MWIS was acceptable (α=0.71-0.81), and correlation analyses also confirmed its construct validity as expected. Workplace incivility was associated with lower workgroup civility, lower supervisor and coworker support, higher workplace bullying, higher psychological distress, higher intention to leave, and lower work engagement. Confirmatory factor analyses showed that the original three-factor model (supervisor incivility, coworker incivility, and instigated incivility) fitted moderately in both Japan and Canada data, though the privacy/overfamiliarity factor was additionally extracted from exploratory factor analysis for the J-MWIS. The results of this study suggested that the J-MWIS has moderate internal consistency reliability and good construct validity.

    To examine student incivility in radiography classrooms by exploring the prevalence of uncivil behaviors along with the classroom management strategies educators use to manage and prevent classroom disruptions. A survey was designed to collect data on the severity and frequency of uncivil student behaviors, classroom management strategies used to address minor and major behavioral issues, and techniques to prevent student incivility. The participants were educators in radiography programs accredited by the Joint Review Committee on Education in Radiologic Technology. Findings indicated that severe uncivil student behaviors in radiography classrooms do not occur as often as behaviors classified as less severe. Radiography educators in this study used a variety of strategies and techniques to manage and prevent student incivility; however, radiography educators who received formal training in classroom management reported fewer incidents of student incivility than those who had not received formal training. The participants in this study took a proactive approach to addressing severe behavioral issues in the classroom. Many radiography educators transition from the clinical environment to the classroom setting with little to no formal training in classroom management. Radiography educators are encouraged to attend formal training sessions to learn how to manage the higher education classroom effectively. Student incivility is present in radiography classrooms. This study provides a foundation for future research on incivility. ©2017 American Society of Radiologic Technologists.

    2018-04-23

    This study examines the role of negative work rumination and recovery experiences in explaining the association between workplace incivility and employee insomnia symptoms. Drawing on the perseverative cognition model of stress and the effort-recovery model, we hypothesize a moderated mediation model in which workplace incivility is associated with insomnia symptoms via negative work rumination. This indirect effect is proposed to be conditional on employees' reported level of recovery experiences (i.e., psychological detachment from work and relaxation during nonwork time). In examining this model, we further establish a link between workplace incivility and sleep and identify one pathway to explain this relationship, as well as resources that may be used to halt the negative spillover of workplace incivility on sleep. Based on a sample of 699 U.S. Forest Service employees, we find support for a moderated mediation model in which the association between workplace incivility and increased insomnia symptoms via increased negative work rumination was weakest for employees reporting high levels of recovery experiences during nonwork time. Findings from the current study contribute to our understanding of why workplace incivility is associated with nonwork outcomes, as well as point to implications for interventions aimed at promoting employees' recovery from work.

    2016-07-01

    The authors present a short, valid, gender invariant measure of workplace incivility that should have a high degree of utility in a variety of research designs, especially those concerned with reducing participant burden such as experience sampling and multiwave longitudinal designs. Given ongoing concerns about the psychometric properties of workplace mistreatment constructs, they validated a 4-item measure of experienced incivility based on series of 3 independent field studies (N = 2,636). In addition to retaining items on the basis of employee rated conceptual alignment (i.e., judgmental criteria) with a standard incivility definition (i.e., ambiguous intent to harm), items were also chosen based on external criteria in terms of their ability to explain incremental variance in outcomes of interest (e.g., role overload, interpersonal deviance). Items with large systematic relationships with other mistreatment constructs (i.e., abusive supervision, supervisor undermining) were excluded. In turn, the authors demonstrated that the 4-item measure is gender invariant, a critical issue that has received limited attention in the literature to date. They also experimentally investigated the effect of recall window (2 weeks, 1 month, 1 year) and found a differential pattern of effect sizes for various outcomes of interest. A fourth independent field study was conducted as a practical application of the measure within a longitudinal framework. An autoregressive model examining experienced incivility and counterproductive work behaviors was tested. Data was collected from a sample of 278 respondents at 3 time points with 1 month between assessments. Implications of these findings are discussed.

Please note that, in all the situations we present, the names are fictitious and used only to improve clarity.   In 2011, the Canadian HR Reporter published several articles by Sharone Bar-David on workplace incivility (I would encourage you to read them here). These articles can shed some light on an internal issue here at CERN: what happens when there are violations of the Code of Conduct that we may face every day? Such incivilities can fly under the organizational radar and are not up to the level of any administrative or disciplinary action foreseen in the CERN Staff Rules and Regulations. However, if such breaches in respectful behaviour are tolerated continuously and nothing is done about them, they can create a toxic work climate.

  6. A Sorrow Halved? A Daily Diary Study on Talking About Experienced Workplace Incivility and Next-Morning Negative Affect.

    Tremmel, Stephanie; Sonnentag, Sabine

    2017-08-31

    Incivility by coworkers and customers can have detrimental consequences for employees' affective well-being at work. However, little is known about whether incivility also impairs employees' affect at home and how long these negative effects may last. In this diary study, we examine whether incivility by coworkers and customers is related to next-morning negative affect via negative affect at the end of the workday and at bedtime, and investigate different modes of social sharing (i.e., conversations about experienced mistreatment) as day-level moderators of this relationship. Daily diary data collected over 10 workdays (N = 113 employees) revealed that coworker incivility was indirectly related to bedtime negative affect via negative affect at the end of the workday, and customer incivility was indirectly related to next-morning negative affect via negative affect at the end of the workday and at bedtime. Although we found no moderating effect for conversations in an affective sharing mode (i.e., conversation partners provide comfort and consolation), the relationship between workplace incivility and employees' negative affect was buffered by conversations in a cognitive sharing mode (i.e., conversation partners suggest alternative explanations or reappraisal of uncivil behavior). In line with social sharing theory, our results suggest that talking about experienced mistreatment can, under specific circumstances, offset the negative relationship of uncivil coworker and customer behavior and employees' negative affect. This study advances current research on workplace incivility by studying negative affect 3 times a day and thus sheds light on the mechanism connecting workplace incivility and employees' affective well-being at home.

  7. Does Faculty Incivility in Nursing Education Affect Emergency Nursing Practice?

    Science.gov (United States)

    Stokes, Pamela

    Incivility in nursing education is a complicated problem which causes disruptions in the learning process and negatively affects future nursing practice. This mixed method research study described incivility as well as incivility's effects through extensive literature review and application of a modified Incivility in Nursing Education (INE) survey. The INE included six demographic items, four quantitative sections, and five open-ended questions. The survey examined emergency nurses' perceptions of incivility and how the experience affected their personal nursing practice. The INE was initially tested in a 2004 pilot study by Dr. Cynthia Clark. For this research study, modifications were made to examine specifically emergency nurse's perceptions of incivility and the effects on their practice. The population was a group of nurses who were members of the emergency nurses association in a Midwestern state. In the quantitative component of the Incivility in Nursing Education (INE) survey, the Likert scale questions indicated that the majority of the participants reported witnessing or experiencing the uncivil behaviors. In the qualitative section of the INE survey, the participants reported that although they have not seen incivility within their own academic career, they had observed faculty incivility with nursing students when the participants were assigned as preceptors as part of their emergency nursing practice.

    Full Text Available The present study examines the association between team incivility climate and team members’ perceived support for innovation. To extend findings on the negative effects of incivility (which are low intensity deviant behaviors, such as rudeness in studies focusing on the individual level, the effects of organizational incivility are examined at the work team level. Drawing on the spiral model of incivility and the literature on teams, this study suggests that team incivility climate has a negative impact on perceived support for innovation through team members’ teamwork behaviors. Using data collected from 411 subordinates on 62 work teams, the hypothesized mediation model is tested. The results show a negative effect of team incivility climate on teamwork and a positive effect of teamwork on perceived support for innovation, supporting the hypothesized negative indirect effect. Research and practical implications for organizational sustainability are discussed.

    Birkeland, Ide Katrine; Nerstad, Christina

    2016-01-01

    This study explored the relationship between obsessive passion for work and incivility instigations, as well as the moderating role of a mastery motivational climate. A longitudinal, 3-wave study was conducted among 1,263 employees from a large Norwegian workers' union across a 10-month time span. The results show that obsessive passion for work relates positively to incivility instigations and that this relationship is stable over time. Building on the person-environment fit perspective, we find that the relationship between obsessive passion for work and incivility instigations is stronger for employees with both high levels of obsessive passion and high perceptions of a mastery climate. Our results underline the importance of considering not only the individual in his or her context but also of considering the match between the individual's values and the contextual values.

    2011-01-01

    This study extended incivility research beyond the confines of the workplace by exploring the relationships between incivility, work-to-family conflict and family support. Data collected from 180 employees from various organizations in Singapore showed that incivility is not a rare phenomenon in Asian cultures. Employees experienced more incivility from superiors than coworkers or subordinates, and these experiences were related to different outcomes. Coworker-initiated incivility was associated with decreased coworker satisfaction, increased perceptions of unfair treatment, and increased depression. On the other hand, superior-initiated incivility was associated with decreased supervisor satisfaction and increased work-to-family conflict. Results also revealed that employees with high family support showed stronger relationships between workplace incivility and negative outcomes, compared with employees with low family support.

    To determine whether nurse coworker incivility is associated with the nurse work environment, defined as organisational characteristics that promote nurse autonomy. Workplace incivility can negatively affect nurses, hospitals and patients. Plentiful evidence documents that nurses working in better nurse work environments have improved job and health outcomes. There is minimal knowledge about how nurse coworker incivility relates to the United States nurse work environment. Quantitative, cross-sectional. Data were collected through online surveys of registered nurses in a southwestern United States health system. The survey content included the National Quality Forum-endorsed Practice Environment Scale of the Nursing Work Index and the Workplace Incivility Scale. Data analyses were descriptive and correlational. Mean levels of incivility were low in this sample of 233 staff nurses. Incivility occurred 'sporadically' (mean = 0.58; range 0.00-5.29). The nurse work environment was rated highly (mean = 3.10; range of 1.00-4.00). The nurse work environment was significantly inversely associated with coworker incivility. The nurse manager qualities were the principal factor of the nurse work environment associated with incivility. Supportive nurse managers reduce coworker incivility. Nurse managers can shape nurse work environments to prevent nurse incivility. © 2017 John Wiley & Sons Ltd.

    2017-12-13

    Incivility in nursing education can adversely affect the academic environment, the learning outcomes, and safety. Nursing faculty (NF) and nursing students (NS) contribute to the academic incivility. Little is known about the extent of NF academic incivility in the Middle East region. This study aimed at exploring the perceptions and extent of NF academic incivility in an undergraduate nursing program of a public university in Oman. A cross sectional survey was used to collect data from 155 undergraduate NS and 40 NF about faculty academic incivility. Data was collected using the Incivility in Nursing Education Survey. The majority of NS and NF had similar perceptions about disruptive faculty behaviors. The incidence of faculty incivility was low (Mean = 1.5). The disruptive behaviors with the highest incidence were arriving late for scheduled activities, leaving schedule activities early, cancelling scheduled activities without warning, ineffective teaching styles and methods, and subjective grading. The most common uncivil faculty behaviors reported by participants were general taunts or disrespect to other NF, challenges to other faculty knowledge or credibility, and general taunts or disrespect to NS. The relatively low level of NF academic incivility could still affect the performance of some students, faculty, and program outcomes. Academic institutions need to ensure a policy of zero tolerance to all academic incivility, and regular monitoring and evaluation as part of the prevention strategies.

  14. Associations between health and different types of environmental incivility: a Scotland-wide study.

    2009-11-01

    Concern about the impact of the environment on health and well-being has tended to focus on the physical effects of exposure to toxic and infectious substances, and on the impact of large-scale infrastructures. Less attention has been paid to the possible psychosocial consequences of people's subjective perceptions of their everyday, street-level environment, such as the incidence of litter and graffiti. As little is known about the potential relative importance for health of perceptions of different types of environmental incivility, a module was developed for inclusion in the 2004 Scottish Social Attitudes survey in order to investigate this relationship. A random sample of 1637 adults living across a range of neighbourhoods throughout Scotland was interviewed. Respondents were asked to rate their local area on a range of possible environmental incivilities. These incivilities were subsequently grouped into three domains: (i) street-level incivilities (e.g. litter, graffiti); (ii) large-scale infrastructural incivilities (e.g. telephone masts); and (iii) the absence of environmental goods (e.g. safe play areas for children). For each of the three domains, the authors examined the degree to which they were thought to pose a problem locally, and how far these perceptions varied between those living in deprived areas and those living in less-deprived areas. Subsequently, the relationships between these perceptions and self-assessed health and health behaviours were explored, after controlling for gender, age and social class. Respondents with the highest levels of perceived street-level incivilities were almost twice as likely as those who perceived the lowest levels of street-level incivilities to report frequent feelings of anxiety and depression. Perceived absence of environmental goods was associated with increased anxiety (2.5 times more likely) and depression (90% more likely), and a 50% increased likelihood of being a smoker. Few associations with health were

  16. A qualitative and quantitative examination of the antecedents of customer incivility.

    Sliter, Michael; Jones, Morgan

    2016-04-01

    Customer incivility is known to have a negative impact on employees working in service jobs. Despite an understanding of the negative outcomes of customer incivility (e.g., burnout, disengagement, absenteeism), little research has investigated antecedents of this low-intensity deviant behavior. This is a clear oversight, given that understanding antecedents of customer incivility is essential for determining methods for reducing this stressor. As such, we conducted 2 studies examining these antecedents. For Study 1, we used a qualitative approach, assessing customer incivility from the perspective of the customer. Three overall themes (with 13 subthemes) emerged that could potentially lead to customer incivility: characteristics of the customer, characteristics of the organization/environment, and characteristics of the service employee. In Study 2, we conducted a quantitative study to investigate-from the perspective of the service employee-customer incivility antecedents that could be potentially controlled by the organization, either through changing the work environment or the employee (through training and selection). The results of a 2 time-point survey study showed that the service environment, service rep incivility, service orientation, agreeableness, and neuroticism served as antecedents to customer incivility. Practical implications are discussed, identifying options for organizational leaders interested in reducing customer incivility, and advice is provided for researchers seeking to further examine the antecedents of customer incivility.

  17. Cell phone use while driving and attributable crash risk.

    Farmer, Charles M; Braitman, Keli A; Lund, Adrian K

    2010-10-01

    Prior research has estimated that crash risk is 4 times higher when talking on a cell phone versus not talking. The objectives of this study were to estimate the extent to which drivers talk on cell phones while driving and to compute the implied annual number of crashes that could have been avoided if driver cell phone use were restricted. A national survey of approximately 1200 U.S. drivers was conducted. Respondents were asked to approximate the amount of time spent driving during a given day, number of cell phone calls made or received, and amount of driving time spent talking on a cell phone. Population attributable risk (PAR) was computed for each combination of driver gender, driver age, day of week, and time of day. These were multiplied by the corresponding crash counts to estimate the number of crashes that could have been avoided. On average, drivers were talking on cell phones approximately 7 percent of the time while driving. Rates were higher on weekdays (8%), in the afternoon and evening (8%), and for drivers younger than 30 (16%). Based on these use rates, restricting cell phones while driving could have prevented an estimated 22 percent (i.e., 1.3 million) of the crashes in 2008. Although increased rates of cell phone use while driving should be leading to increased crash rates, crash rates have been declining. Reasons for this paradox are unclear. One possibility is that the increase in cell phone use and crash risk due to cell phone use have been overestimated. Another possibility is that cell phone use has supplanted other driving distractions that were similarly hazardous.

    A robust and efficient lane detection system is an essential component of Lane Departure Warning Systems, which are commonly used in many vision-based Driver Assistance Systems (DAS) in intelligent transportation. Various computation platforms have been proposed in the past few years for the implementation of driver assistance systems (e.g., PC, laptop, integrated chips, PlayStation, and so on). In this paper, we propose a new platform for the implementation of lane detection, which is based on a mobile phone (the iPhone). Due to physical limitations of the iPhone w.r.t. memory and computing power, a simple and efficient lane detection algorithm using a Hough transform is developed and implemented on the iPhone, as existing algorithms developed based on the PC platform are not suitable for mobile phone devices (currently). Experiments of the lane detection algorithm are made both on PC and on iPhone.

    Full Text Available The iPhone mobile from Apple Inc. is one of the most notable phones on the market thanks to its simple and user-friendly interface and ever growing pool of available high quality applications for both personal and business use. The increasing use of iPhone mobiles leads forensics practitioners towards the need for tools to access and analyze the information stored in the device. This research aims at describing how to forensically analyze a logical backup of an iPhone made by the Apple iTunes utility, understanding its structure and creating a simple tool to automate the process of decoding and analyzing the data. It was found that significant data of forensic value such as e-mail messages, text and multimedia messages, calendar events, browsing history, GPRS locations, contacts, call history and voicemail recordings can be retrieved using this method of iPhone acquisition.

    2017-10-01

    This research examines group-level perceptions of transformational leadership (TFL) as negative longitudinal predictors of witnessing person-related (e.g., insults/affronts) and work-related (e.g., negation/intentional work overload) acts of incivility at work. Witnessing workplace incivility was also postulated to negatively predict employee need satisfaction. Data were collected among production employees in different Canadian plants of a major manufacturing company ( N = 344) who worked for 42 different managers ( M group size = 9.76). Two waves of data collection occurred 1 year apart. Results from multilevel analyses showed that workgroups where managers were perceived to engage in more frequent TFL behaviors reported reduced levels of person- and work-related incivility 1 year later. However, group-level incivility did not predict change in group-level need satisfaction 1 year later. At the individual level, results showed that witnessing higher levels of person-related incivility than one's colleagues predicted reduced satisfaction of the need for relatedness 1 year later. These longitudinal findings build upon previous literature by identifying TFL as a potential managerial strategy to reduce incivility in workgroups over time. They also show that mere exposure to workplace misbehavior still affects employees' adjustment, suggesting that every effort to reduce deviance in workplaces is worthwhile.

    Full Text Available Cell phones are already prime targets for theft. The increasing functionality of cell phones is making them even more attractive. With the increase of cell phone functionality including personal digital assistance, banking, e-commerce, remote work, internet access and entertainment, more and more confidential data is stored on these devices. What is protecting this confidential data stored on cell phones? Studies have shown that even though most of the cell phone users are aware of the PIN security feature more than 50% of them are not using it either because of the lack of confidence in it or because of the inconvenience. A large majority of those users believes that an alternative approach to security would be a good idea.

    Full Text Available Background: Many articles have studied workplace incivility and its influence on outcomes, but very few have been conducted to assess how to prevent this issue. In this study, we aimed to determine how to prevent workplace incivility from the nurses' perspective. Materials and Methods: This was a qualitative study which was based on a conventional content analysis approach. Thirty four nurses (25 to 52 years old from seven training hospitals in Tabriz, Iran were selected through purposive sampling. Thirty six semi-structured interviews and eight field notes were analyzed. Results: The data analysis revealed 417 codes, ten categories, three subthemes and one theme, that is, A Need for a Comprehensive Attempt. Attempt of organization, nurses, and public as subthemes are needed to prevent workplace incivility. Conclusions: The findings of the study indicated that a comprehensive and systematic attempt was needed to prevent incivility. Nurses should try to improve their skills; officials should try to show the real image and position of nurses and hospitals to the community.

    Campana, Kristie L; Hammoud, Sammira

    2015-09-01

    To determine whether interpersonal and informational justice influence the association between daily experiences of incivility and burnout among nurses. Research has suggested that incivility is a concern for managers. Nurses regularly experience incivility, particularly from their patients and patients' families. Incivility, in turn, can increase symptoms of burnout. Seventy-five nurses provided data on interpersonal and informational justice within their organisation. During five working days, nurses completed a twice-daily survey assessing incivility and burnout. Hierarchical linear modelling analyses examined the main effects and interaction effects of the three variables on burnout. Incivility was positively associated with burnout. In addition, interpersonal justice strengthened the incivility-burnout relationship. Informational justice did not significantly affect the incivility-burnout relationship. Incivility is associated with more burnout. The work environment also influences burnout; when organisations provide informational justice, nurses experience less burnout. In organisations where interpersonal justice is high, nurses are more likely to experience burnout. Nursing managers can help employees by ensuring that management's decisions are transparent. In addition, managers should be aware that in organisations with higher interpersonal justice, nurses might be more likely to experience symptoms of burnout as a result of incivility from patients and their families. © 2013 John Wiley & Sons Ltd.

    2016-01-01

    We present a review of the studies that have been published about addiction to cell phones. We analyze the concept of cell-phone addiction as well as its prevalence, study methodologies, psychological features, and associated psychiatric comorbidities. Research in this field has generally evolved from a global view of the cell phone as a device to its analysis via applications and contents. The diversity of criteria and methodological approaches that have been used is notable, as is a certain lack of conceptual delimitation that has resulted in a broad spread of prevalent data. There is a consensus about the existence of cell-phone addiction, but the delimitation and criteria used by various researchers vary. Cell-phone addiction shows a distinct user profile that differentiates it from Internet addiction. Without evidence pointing to the influence of cultural level and socioeconomic status, the pattern of abuse is greatest among young people, primarily females. Intercultural and geographical differences have not been sufficiently studied. The problematic use of cell phones has been associated with personality variables, such as extraversion, neuroticism, self-esteem, impulsivity, self-identity, and self-image. Similarly, sleep disturbance, anxiety, stress, and, to a lesser extent, depression, which are also associated with Internet abuse, have been associated with problematic cell-phone use. In addition, the present review reveals the coexistence relationship between problematic cell-phone use and substance use such as tobacco and alcohol.

    Standard operating systems and Bluetooth technology will be a trend for future cell phone features. These will enable cell phone viruses to spread either through SMS or by sending Bluetooth requests when cell phones are physically close enough. The difference in spreading methods gives these two types of viruses' different epidemiological characteristics. SMS viruses' spread is mainly based on people's social connections, whereas the spreading of Bluetooth viruses is affected by people's mobility patterns and population distribution. Using cell phone data recording calls, SMS and locations of more than 6 million users, we study the spread of SMS and Bluetooth viruses and characterize how the social network and the mobility of mobile phone users affect such spreading processes.

    2012-03-01

    The current study was designed to extend the interpersonal deviance literature into the online domain by examining the incidence and impact of supervisor cyber incivility and neuroticism on employee outcomes at work. Conservation of Resources (COR) theory was used as the guiding framework because cyber incivility is thought to deplete energetic resources in much the same way that other stressors do, ultimately leading to negative outcomes like burnout. Results indicate that supervisor cyber incivility is positively related to burnout, absenteeism, and turnover intentions. Support was also found for the role of neuroticism as a moderator of the relationship between supervisor cyber incivility and outcomes. In general, the relations between cyber incivility and outcomes were stronger for those individuals reporting higher levels of neuroticism. Results are discussed in terms of COR theory, and possible mechanisms for the role of neuroticism in the stressor-strain relationship are discussed. The current study highlights the importance of understanding workplace online behavior and its impact on employee health and organizational well-being. Future research directions examining online interpersonal deviance are suggested.

    With the advancement in mobile technology, smartphone retinal photography is becoming a popular practice. However, there is limited information about the safety of the latest smartphones used for retinal photography. This study aims to determine the photobiological risk of iPhone 6 and iPhone 6 plus when used in conjunction with a 20Diopter condensing lens for retinal photography. iPhone 6 and iPhone 6 plus (Apple, Cupertino, CA) were used in this study. The geometrical setup of the study was similar to the indirect ophthalmoscopy technique. The phone was set up at one end of the bench with its flash turned on at maximal brightness; a 20 Dioptre lens was placed 15 cm away from the phone. The light that passes through the lens was measured with a spectroradiometer and an illuminance probe at the other end to determine the spectral profile, spatial irradiance, radiant power emitted by the phone's flash. Trigonometric and lens formula were applied to determine the field of view and retinal surface in order to determine the weighted retinal irradiance and weighted retinal radiant exposure. Taking ocular transmission and the distribution of the beam's spatial irradiance into account, the weighted retinal irradiance is 1.40 mW/cm 2 and the weighted retinal radiant exposure is 56.25 mJ/cm 2 . The peak weighted foveal irradiance is 1.61 mW/cm 2 . Our study concluded that the photobiological risk posed by iPhone 6 indirect ophthalmoscopy was at least 1 order of magnitude below the safety limits set by the ISO15004-2.2.

    Cortina, L M; Magley, V J; Williams, J H; Langhout, R D

    2001-01-01

    This study extends the literature on interpersonal mistreatment in the workplace by examining the incidence, targets, instigators, and impact of incivility (e.g., disrespect, condescension, degradation). Data were collected from 1,180 public-sector employees, 71% of whom reported some experience of workplace incivility in the previous 5 years. As many as one third of the most powerful individuals within the organization instigated these uncivil acts. Although women endured greater frequencies of incivility than did men, both genders experienced similarly negative effects on job satisfaction, job withdrawal, and career salience. Uncivil workplace experiences were also associated with greater psychological distress; however, indices of psychological and physical health were relatively unaffected. The authors discuss these findings in the context of organizational and cognitive stress theories.

    2018-04-01

    Workplace incivility has significant adverse consequences for targets. However, we know remarkably little about how targets of incivility cope and even less about which coping strategies are effective. Drawing on the coping process of the transactional model of stress, we examine confrontation as a form of problem-focused coping and avoidance as a form of emotion-focused coping in response to incivility. We examine the effects of these coping strategies on reoccurrence of incivility, incivility enacted by targets, psychological forgiveness, and emotional exhaustion. Focusing on the target's perspective of a series of uncivil interactions between a target and perpetrator, we conducted a 3-wave study of employees from various occupations. Employing the critical incident technique, participants reported on an incident of workplace incivility, and then answered a series of questions over 3 waves of data collection regarding their interactions with this perpetrator. Our findings suggest that confrontation and avoidance are ineffective in preventing reoccurrence of incivility. Avoidance can additionally lead to increased emotional exhaustion, target-enacted incivility, and lower psychological forgiveness. However, confrontation coping has promise with regards to eliciting positive outcomes such as psychological forgiveness that are beneficial to interpersonal workplace relationships.

    2013-05-01

    A thorough understanding of why we hold a cell phone to a particular ear may be of importance when studying the impact of cell phone safety. To determine if there is an obvious association between sidedness of cell phone use and auditory hemispheric dominance (AHD) or language hemispheric dominance (LHD). It is known that 70% to 95% of the population are right-handed, and of these, 96% have left-brain LHD. We have observed that most people use their cell phones in their right ear. An Internet survey was e-mailed to individuals through surveymonkey.com. The survey used a modified Edinburgh Handedness Inventory protocol. Sample questions surveyed which hand was used to write with, whether the right or left ear was used for phone conversations, as well as whether a brain tumor was present. General community. An Internet survey was randomly e-mailed to 5000 individuals selected from an otology online group, patients undergoing Wada testing and functional magnetic resonance imaging, as well as persons on the university listserv, of which 717 surveys were completed. Determination of hemispheric dominance based on preferred ear for cell phone use. A total of 717 surveys were returned. Ninety percent of the respondents were right handed, and 9% were left handed. Sixty-eight percent of the right-handed people used the cell phone in their right ear, 25% in the left ear, and 7% had no preference. Seventy-two of the left-handed respondents used their left ear, 23% used their right ear, and 5% had no preference. Cell phone use averaged 540 minutes per month over the past 9 years. An association exists between hand dominance laterality of cell phone use (73%) and our ability to predict hemispheric dominance. Most right-handed people have left-brain LHD and use their cell phone in their right ear. Similarly, most left-handed people use their cell phone in their left ear. Our study suggests that AHD may differ from LHD owing to the difference in handedness and cell phone ear use

  8. Ethnicity and cultural values as predictors of the occurrence and impact of experienced workplace incivility.

    2015-04-01

    Workplace incivility is a subtle type of deviant work behavior that is low in intensity and violates workplace norms of respect. Past research demonstrates the harmful impact of incivility on work attitudes and employee wellbeing; however, little is known about how incivility is experienced by individuals of different ethnicities and cultural orientations. In the current study, we compared the amount and impact of workplace incivility that was experienced by Hispanic and white, non-Hispanic employees. Further, we examined whether cultural dimensions of vertical and horizontal individualism and collectivism moderated the relationships between workplace incivility and work and health outcomes. A sample of 262 university employees (50% Hispanic; 63% female) provided self-reports of experienced incivility, burnout, job satisfaction, and cultural values. Although male Hispanic employees experienced more incivility, female Hispanic employees experienced less incivility than non-Hispanic employees of the same gender. Hispanic employees displayed greater resilience against the impact of incivility on job satisfaction and burnout, compared with non-Hispanic employees. Additionally, employees with strong horizontal collectivism values (emphasizing sociability) were more resilient against the impact of incivility on burnout, whereas employees with strong horizontal individualism values (emphasizing self-reliance) were more susceptible to burnout and dissatisfaction when faced with incivility. These findings suggest that employees' ethnicity and cultural values may increase or decrease their vulnerability to the impact of incivility at work. (c) 2015 APA, all rights reserved).

  9. The relationship between leadership style and nurse-to-nurse incivility: turning the lens inward.

    Kaiser, Jennifer A

    2017-03-01

    The aim of this study was to examine the impact of leadership styles on the reported rates of lateral hostility in nurses. Previous explanations of horizontal incivility point to oppressed group behaviour and socialisation of nurses. Leadership and organisational culture are known to have a profound impact on workplace behaviour, yet few studies have examined the relationship between leadership style and nurse-to-nurse incivility. A survey was used to assess the perceived levels of incivility and the leadership styles experienced by 237 participants defined as 'staff nurses'. Transformational leadership style had the strongest correlation with low levels of incivility. Staff input and leader/staff teamwork also influence staff incivility. Leadership style is not a definitive factor of incivility, but leader behaviours impact the level of incivility between staff nurses. The relationship between leaders and staff and the empowerment of staff have the strongest impact on nurse incivility. The factors found to correlate with incivility in this study are under the influence of nurse leaders. Relationships and interpersonal dynamics must be attended to. Leaders can also instil the structures known to foster nurse empowerment, which are discussed. © 2016 John Wiley & Sons Ltd.

    2018-01-01

    In spite of the considerable number of studies on co-worker incivility, knowledge on this topic needs to be further enhanced. In particular, no studies have focused on the reciprocal nature of the relationship of incivility with other important aspects of working life, i.e. employee well-being and the quality of the working process. The aim of the present study was to examine the cross-lagged associations among co-worker incivility, work-related exhaustion, and organisational efficiency in a sample of healthcare workers. Based on the conservation of resource theory, we hypothesised that those three variables affect each other reciprocally over the time. Data from a two-wave study design (with a one-year time lag) were utilised, and cross-lagged structural equation models were performed. Results confirmed that incivility and efficiency affected each other reciprocally over time. On the other hand, whereas incivility positively predicted exhaustion and exhaustion at inversely predicted organisational efficiency, the opposite paths were found to be not significant. The study suggests that efficiency is crucial for understanding incivility because it operates both as its cause and as its outcome. Interventions aimed at promoting civility and respect in the workplace may help prevent co-worker incivility, work-related exhaustion, and enhance organisational efficiency.

  14. New Nursing Faculty and Incivility: Applying Mindfulness-Based Strategies.

    Science.gov (United States)

    Green, Cheryl

    Workplace incivility remains a problem within the nursing profession. As nurse leaders, we must recognize and not ignore the complexity of cultures that have adapted incivility into the work environment. Nursing education is a discipline that requires collaborative team work, independent drive, and commitment. New nursing faculty experiencing incivility can use mindfulness-based meditation approaches to cope with uncivil behaviors experienced within the workplace. Nurse educators applying the concepts of mindfulness can learn how to provide themselves self-care by reducing stress, as enhanced daily awareness of peace and calm are incorporated into their lifestyle. Mindfulness provides a realization that control can only be given to other persons when an individual allows or accepts another's negative behaviors. Awareness of the value and importance of oneself can assist the nurse educator experiencing incivility to maintain his or her emotional, physical, and spiritual health despite the volatility of the work environment.

    To examine the relationship between nursing students' exposure to various forms of incivility in acute care practice settings and their experience of burnout. Given that staff nurses and new nurse graduates are experiencing incivility and burnout in the workplace, it is plausible that nursing students share similar experiences in professional practice settings. A cross-sectional survey design was used to assess Year 4 nursing students' (n=126) perceptions of their experiences of incivility and burnout in the clinical learning environment. Students completed instruments to assess frequency of uncivil behaviors experienced during the past six months from nursing staff, clinical instructors, and other health professionals in the acute care practice setting and to measure student burnout. Reported incidences of incivility in the practice setting were related to burnout. Higher rates of incivility, particularly from staff nurses, were associated with higher levels of both components of burnout (emotional exhaustion and cynicism).

    Hallett, Charlene; Lambert, Anthony; Regan, Michael A

    2011-05-01

    This study investigated (i) the prevalence of conversing on a cell phone while driving in New Zealand, (ii) respondents' perception of risk regarding this behaviour and (iii) attitudes towards legislation banning cell phone use while driving. In addition, the study examined the association between the prevalence of conversing on a cell phone and risk perception. Anonymous, self-reported, survey data was collected via the internet from 1057 drivers nationwide regarding the frequency of conversing on a cell phone, including hands-free and hand-held conversing, risk perception, views on legislation, and demographic information. A positive relationship was found between the frequency of conversing on a cell phone and risk perception; that is, as the frequency of conversing on a cell phone increased, the perceived risk of this behaviour decreased.

  19. WORKPLACE INCIVILITY AMONG PORTUGUESE HOTEL EMPLO YEES: IS LACK OF RESPECT BURNING THEM OUT?

    Directory of Open Access Journals (Sweden)

    Martina Nitzsche

    2018-03-01

    Full Text Available Workplace incivility is defined as rude behaviour that violates social norms at work. It has been linked to psychological distress (burnout, mainly in healthcare and educational settings. Burnout is a serious public health concern. Studies addressing the impact of workplace incivility on employee well-being in the hospitality industry are scarce. The primary aim of this study was to examine the relationship between workplace incivility and burnout among hotel employees. Cross-sectional data for 385 Portuguese hotel employees (54% male; Mage = 33.9, SD = 11.3 were analysed using bootstrap regression models. Results revealed that (1 supervisor incivility was significantly more frequent than coworker incivility; (2 supervisor and co-worker incivility were significant positive predictors of emotional exhaustion and cynicism, the core components of burnout; (3 supervisor incivility was the stronger predictor of emotional exhaustion, and co-worker incivility the stronger predictor of cynicism; and (4 severe burnout was highly prevalent in our sample. This study provides insight into the phenomena of workplace incivility and burnout among Portuguese hotel employees. Our results have practical value for management strategies aiming to prevent or reduce burnout, which in turn has the potential to enhance individual, group, customer and organizational outcomes within the hospitality industry.

  20. The validation of a workplace incivility scale within the South African banking industry

    Full Text Available Orientation: Workplace incivility holds consequences for both individuals and organisations. Managers are becoming increasingly aware of this phenomenon. Currently, there is no workplace incivility scale validated for use within the South African context. Research purpose: To investigate the reliability and validity of the adapted workplace incivility scale by Leiter and colleagues for use within South Africa. Motivation for the study: As it is currently difficult to measure workplace incivility within the South African context because of the lack of a valid and reliable scale, it is necessary to validate such a scale. Research design, approach and method: A cross-sectional research approach was used for the study. Convenience sampling (N = 345 was used within the South African banking industry. Specifically, the factor structure, convergent validity, discriminant validity and predictive validity were investigated in order to establish the overall validity of the scale. Main findings: The results confirmed that the scale showed a three-factor structure as bestfitting with acceptable reliability coefficients. Furthermore, discriminant validity could be shown between workplace incivility and workplace bullying, that is, supporting that these two constructs are not the same phenomenon. In terms of relationships, colleague incivility did not significantly predict any of the outcome variables and instigated incivility only being a negative predictor of job satisfaction and a borderline statistically significant negative predictor of work engagement. However, supervisor incivility predicted all the outcomes negatively. Practical/Managerial implications: Based on the results, workplace incivility should be addressed because of the harmful effects it can have, not only on employees but also on organisations. It is therefore necessary for managers to create awareness of workplace incivility in order to ensure that it does not integrate within the

    2017-07-17

    Managing incivility in academic settings is among the basic concerns and challenges of most educational systems, including nursing education. Incivility management cannot be considered devoid of disruptive behaviors. However, incivility management is a complexphenomenon upon which few studies are conducted. The present study aims at discovering teachers and students' experiences regarding incivility and developing an approach to manage nursing students' incivility. The present study was conducted based on the qualitative research design of the grounded theory methodology. This study was conducted at schools of nursing in academic settings in Iran. Study participants in the present study include nurse teachers (N=20) and nursing students (N=9). In-depth semi-structured interviews were conducted using theoretical and purposive sampling. Constant comparative analysis was used for data analysis. The results include four main categories; (1) deterioration of learning; (2) dominant individual and organisational culture; (3) guided democracy; and (4) movement toward professionalism. Guided democracy is recognised as the main basic psychosocial process for incivility management. Incivility management is pursued to help learners develop professional performance. As indicated by the results of the present study, guided democracy is an effective strategy for incivility management in nursing education. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Sliter, Michael; Jex, Steve; Wolford, Katherine; McInnerney, Joanne

    2010-10-01

    Because of the large number of people employed in service occupations, customer incivility has become an increasingly prevalent and important workplace stressor. Unfortunately, relatively little research has examined the effects of customer incivility; of the research that does exist, virtually all of it has focused solely on employee mental health outcomes. The present study was designed to replicate previous research linking customer incivility to the emotional exhaustion dimension of burnout and to expand on previous research by examining the effects of customer incivility on customer service quality. In addition, two models were proposed and tested in which emotional labor mediated the relationship between customer incivility and outcomes. Data from 120 bank tellers revealed that customer incivility was positively related to emotional exhaustion and negatively related to customer service performance. In addition, both proposed models were supported. Theoretical and practical implications of the findings and future directions are discussed. © 2010 APA, all rights reserved.

  8. Secondary Behavior of Drivers on Cell Phones.

    Farmer, Charles M; Klauer, Sheila G; McClafferty, Julie A; Guo, Feng

    2015-01-01

    The objective of this study was to determine whether cell phone use by drivers leads to changes in the frequency of other types of potentially distracting behavior. There were 2 main questions of interest: (1) As each driver changes cell phone use, does he or she change the amount of driving time spent on other distracting behavior? (2) As each driver changes cell phone use, does he or she change the amount of driving time spent looking away from the driving task? Day-to-day driving behavior of 105 volunteer subjects was monitored over a period of 1 year. The amount of driving time during each trip spent on tasks secondary to driving (or looking away from the driving task) was correlated to the amount of time on a cell phone, taking into account the relationships among trips taken by the same driver. Drivers spent 42% of the time engaging in at least one secondary activity. Drivers were talking on a cell phone 7% of the time, interacting in some other way with a cell phone 5% of the time, and engaging in some other secondary activity (sometimes in conjunction with cell phone use) 33% of the time. Other than cell phone use, the most common secondary activities were interacting with a passenger (12% of driving time), holding but not otherwise interacting with an object (6%), and talking/singing/dancing to oneself (5%). Drivers were looking straight forward 81% of the time, forward left or right 5% of time, in a mirror 4% of the time, and elsewhere (eyes off driving task) 10% of time. On average, for each 1 percentage point increase in cell phone talking, the other secondary behavior rate decreased by 0.28 percentage points (P cell phone interaction per trip, the other secondary behavior rate decreased by 0.08 percentage points (P =.0558), but the rate of eyes off driving task increased by 0.06 percentage points (P cell phone can be distracting from the driving task, other secondary activities can be equally or more distracting, at least as measured by eye glances

    The aim of this study was to evaluate the effects of exposure to cell phone electromagnetic radiation on the frequency of micronuclei, broken eggs cells, binucleated cells, and karyorrhexis in epithelial cells of the oral mucosa. The sample was composed of 60 cell phone users, who were non-smokers and non-drinkers, and had no clinically visible oral lesions. Cells were obtained from anatomical sites with the highest incidence of oral cancer: lower lip, border of the tongue, and floor of the mouth. The Feulgen reaction was used for quantification of nuclear anomalies in 1,000 cells/slide. A slightly increase in the number of micronucleated cells in the lower lip and in binucleated cells on the floor of the mouth was observed in individuals who used their phones > 60 minutes/week. The analysis also revealed an increased number of broken eggs in the tongue of individuals owning a cell phone for over eight years. Results suggest that exposure to electromagnetic waves emitted by cell phones can increase nuclear abnormalities in individuals who use a cell phone for more than 60 minutes per week and for over eight years. Based on the present findings, we suggest that exposure to electromagnetic radiation emitted by cell phones may interfere with the development of metanuclear anomalies. Therefore, it is demonstrated that, despite a significant increase in these anomalies, the radiation emitted by cell phones among frequent users is within acceptable physiological limits.

    Cell phone use among pedestrians leads to increased cognitive distraction, reduced situation awareness and increases in unsafe behavior. Performing a dual-task, such as talking or texting with a cell phone while walking, may interfere with working memory and result in walking errors. At baseline, thirty-three participants visually located a target 8m ahead; then vision was occluded and they were instructed to walk to the remembered target. One week later participants were assigned to either walk, walk while talking on a cell phone, or walk while texting on a cell phone toward the target with vision occluded. Duration and final location of the heel were noted. Linear distance traveled, lateral angular deviation from the start line, and gait velocity were derived. Changes from baseline to testing were analyzed with paired t-tests. Participants engaged in cell phone use presented with significant reductions in gait velocity (texting: 33% reduction, p=0.01; talking: 16% reduction, p=0.02). Moreover, participants who were texting while walking demonstrated a 61% increase in lateral deviation (p=0.04) and 13% increase in linear distance traveled (p=0.03). These results suggest that the dual-task of walking while using a cell phone impacts executive function and working memory and influences gait to such a degree that it may compromise safety. Importantly, comparison of the two cell phone conditions demonstrates texting creates a significantly greater interference effect on walking than talking on a cell phone.

    2014-01-01

    The goal of this study was to compare cell phone usage behaviors while driving across 3 types of cell phones: handheld (HH) cell phones, portable hands-free (PHF) cell phones, and integrated hands-free (IHF) cell phones. Naturalistic driving data were used to observe HH, PHF, and IHF usage behaviors in participants' own vehicles without any instructions or manipulations by researchers. In addition to naturalistic driving data, drivers provided their personal cell phone call records. Calls during driving were sampled and observed in naturalistically collected video. Calls were reviewed to identify cell phone type used for, and duration of, cell phone subtasks, non-cell phone secondary tasks, and other use behaviors. Drivers in the study self-identified as HH, PHF, or IHF users if they reported using that cell phone type at least 50% of the time. However, each sampled call was classified as HH, PHF, or IHF if the talking/listening subtask was conducted using that cell phone type, without considering the driver's self-reported group. Drivers with PHF or IHF systems also used HH cell phones (IHF group used HH cell phone in 53.2% of the interactions, PHF group used HH cell phone for 55.5% of interactions). Talking/listening on a PHF phone or an IHF phone was significantly longer than talking/listening on an HH phone (P phone call task for HH phones was significantly longer in duration than the end phone call task for PHF and IHF phones. Of all the non-cell phone-related secondary tasks, eating or drinking was found to occur significantly more often during IHF subtasks (0.58%) than in HH subtasks (0.15%). Drivers observed to reach for their cell phone mostly kept their cell phone in the cup holder (36.3%) or in their seat or lap (29.0% of interactions); however, some observed locations may have required drivers to move out of position. Hands-free cell phone technologies reduce the duration of cell phone visual-manual tasks compared to handheld cell phones. However

    Conclusion: The fundamental TPB components were directly associated with the addiction to use a cell phone when driving. The present study has identified that older drivers were considerably less probable to use a cell phone while driving. Also this study showed that males use a cell phone significantly more frequent. More practical road safety measures are required to rebuff and mitigate the effects of using cell phones while driving.

  19. Recycled Cell Phones - A Treasure Trove of Valuable Metals

    Science.gov (United States)

    Sullivan, Daniel E.

    2006-01-01

    This U.S. Geological Survey (USGS) Fact Sheet examines the potential value of recycling the metals found in obsolete cell phones. Cell phones seem ubiquitous in the United States and commonplace throughout most of the world. There were approximately 1 billion cell phones in use worldwide in 2002. In the United States, the number of cell phone subscribers increased from 340,000 in 1985 to 180 million in 2004. Worldwide, cell phone sales have increased from slightly more than 100 million units per year in 1997 to an estimated 779 million units per year in 2005. Cell phone sales are projected to exceed 1 billion units per year in 2009, with an estimated 2.6 billion cell phones in use by the end of that year. The U.S. Environmental Protection Agency estimated that, by 2005, as many as 130 million cell phones would be retired annually in the United States. The nonprofit organization INFORM, Inc., anticipated that, by 2005, a total of 500 million obsolete cell phones would have accumulated in consumers' desk drawers, store rooms, or other storage, awaiting disposal. Typically, cell phones are used for only 1 1/2 years before being replaced. Less than 1 percent of the millions of cell phones retired and discarded annually are recycled. When large numbers of cell phones become obsolete, large quantities of valuable metals end up either in storage or in landfills. The amount of metals potentially recoverable would make a significant addition to total metals recovered from recycling in the United States and would supplement virgin metals derived from mining.

    To identify common catalysts of worker-to-worker violence and incivility in hospital settings. Worker-to-worker violence and incivility are prevalent forms of mistreatment in healthcare workplaces. These are forms of counterproductive work behaviour that can lead to negative outcomes for employees, patients and the organisation overall. Identifying the factors that lead to co-worker mistreatment is a critical first step in the development of interventions targeting these behaviours. Retrospective descriptive study. Qualitative content analysis was conducted on the total sample (n = 141) of employee incident reports of worker-to-worker violence and incivility that were documented in 2011 at a large American hospital system. More than 50% of the incidents involved nurses, and the majority of incidents did not involve physical violence. Two primary themes emerged from the analysis: Work Behaviour and Work Organisation. Incidents in the Work Behaviour category were often sparked by unprofessional behaviour, disagreement over responsibilities for work tasks or methods of patient care, and dissatisfaction with a co-worker's performance. Incidents in the Work Organisation category involved conflicts or aggression arising from failure to following protocol, patient assignments, limited resources and high workload. Incidents of worker-to-worker violence and incivility stemmed from dissatisfaction with employee behaviour or from organisational practices or work constraints. These incident descriptions reflect worker dissatisfaction and frustration, resulting from poor communication and collaboration between employees, all of which threaten work productivity. Violence and incivility between hospital employees can contribute to turnover of top performers, hinder effective teamwork and jeopardise the quality of patient care. Identification of common catalysts for worker-to-worker violence and incivility informs the development of mistreatment prevention programmes that can be

    Cell phones are useful tools with both practical and social benefits. However, using them in the context of face-to-face conversations may be problematic. We consider this behavior a form of ostracism and test its effects on the satisfaction of basic psychological needs for belonging, self-esteem, control, and meaningful existence. In Study 1 participants who recalled a time in which a friend was checking a cell phone during a serious conversation reported feeling more ostracized (ignored and excluded), greater pain, and threat to basic needs than participants recalling a conversation without a cell phone interruption or a control event. Study 2 replicated and extended this effect: Cell phone-induced ostracism's effects were partially mediated by decreased feelings of relational evaluation, and threatened basic needs both in serious and casual conversation contexts. Findings from both studies also indicated that cell phone-induced ostracism hurts women more so than men.

    A previous study found an association between maternal cell phone use during pregnancy and maternal-reported child behaviour problems at age 7. Together with cell phones, cordless phones represent the main exposure source of radiofrequency-electromagnetic fields to the head. Therefore, we assessed the association between maternal cell phone and cordless phone use during pregnancy and teacher-reported and maternal-reported child behaviour problems at age 5. The study was embedded in the Amsterdam Born Children and their Development study, a population-based birth cohort study in Amsterdam, the Netherlands (2003-2004). Teachers and mothers reported child behaviour problems using the Strength and Difficulties Questionnaire at age 5. Maternal cell phone and cordless phone use during pregnancy was asked when children were 7 years old. A total of 2618 children were included. As compared to non-users, those exposed to prenatal cell phone use showed an increased but non-significant association of having teacher-reported overall behaviour problems, although without dose-response relationship with the number of calls (OR=2.12 (95% CI 0.95 to 4.74) for cell phone and cordless phone use with maternal-reported overall behaviour problems remained non-significant. Non-significant associations were found for the specific behaviour problem subscales. Our results do not suggest that maternal cell phone or cordless phone use during pregnancy increases the odds of behaviour problems in their children.

    Full Text Available In reality, workplace incivility has its fair share of attention in organizational research dealing with its causes and effect relationships. In Islam, incivility equates the negative character (akhlak of ridiculing others. Consequently, the purpose of this study is to investigate relationship between the experience of workplace incivility and job attitudes as well as the moderating effect of Muslim religiosity personality, which is measured by Muslim Religiosity-Personality Inventory (MRPI, on the relationships. In other words, this study plans to analyze whether Muslim employees, who possess religiosity personality would be able to endure workplace incivility experiences. Basically, literature by Al-Ghazali, Al-Attas and Al-Raiya on Islamic personality serve as the main foundation of the study. In addition, the works of Baron and Neuman (1998, Andersson & Pearson (1999 and Schilpzand, et. al (2014 were reviewed and a research framework was developed. The quantitative survey consisted of five sections used to measure the experience of workplace incivility, job attitudes, religiosity personality and demographics. A sample of 163 Malaysian Muslim bank workers completed the survey. Four main variables have been analyzed and their descriptive analyses are as the following. Scores for Workplace Incivility variable (M=3.34, SD=.27; Job Satisfaction variable (M=1.79, SD=.65; Organizational Commitment variable (M=2.74, SD=.34 and Muslim Religiosity Personality (M=3.60, SD=.42. As for the Pearson’s Correlation test, the result indicates that Workplace Incivility variable has inverse correlations with both job attitude variables (Job Satisfaction, R=-.611, p=.01; Organizational Commitment, R=.731,p=.01. Meanwhile, the overall model was significant, R2 = .401, F(3, 159 = 24.06, p= .01. Tests to see if the data met the assumption of collinearity indicate that multicollinearity was not a concern (Job Satisfaction, Tolerance = .96, VIF = 1

    There is a critical need for nurses and interprofessional healthcare providers to implement systems thinking (ST) across international borders, addressing incivility and its perilous effects on patient quality and safety. An estimated one million patients die in hospitals worldwide due to avoidable patient-related errors. Establishing safe and civil workplaces using ST is paramount to promoting clear, level-headed thinking from which patient-centered nursing actions can impact health systems. The purpose of the paper is to answer the research question, What ST evidence fosters the effect of workplace civility in practice settings? Whittemore and Knafl's integrative review method guided this study. The quality of articles was determined using Chu et al.'s Mixed Methods Assessment Tool. Thirty-eight studies were reviewed. Themes emerged describing antecedents and consequences of incivility as embedded within complex systems, suggesting improvements for civility and systems/ST in nursing practice. This integrative review provides information about worldwide incivility in nursing practice from a systems perspective. Several models are offered as a means of promoting civility in nursing practice to improve patient quality and safety. Further study is needed regarding incivility and resultant effects on patient quality and safety. © 2018 Wiley Periodicals, Inc.

  9. Youth Culture and Cell Phone

    Full Text Available Iranian youth’s leisure culture has been immediately affected by the digital media culture. As a communicative media, cell phone has crossed borders of youth norms and identity; and in addition to facilitating their communication, has changed its patterns. Applying Bourdieu’s concepts of habitus and field, and relied on the qualitative and quantitative data gathered from the mobile youth users, the present study argues that mobile has produced a new field in which youth’s opportunities for leisure, entertainment, communication, and independence have extended. In addition, cell phone has facilitated and compensated for some defects in public sphere, and therefore empowered youth agency, individuality, and power. Despite this strengthening, cell phone does not cross borders of gender and class differences, or the levels of social capital.

    The aim of this study was to examine the influence of empowering work conditions and workplace incivility on nurses' experiences of burnout and important nurse retention factors identified in the literature. A major cause of turnover among nurses is related to unsatisfying workplaces. Recently, there have been numerous anecdotal reports of uncivil behaviour in health care settings. We examined the impact of workplace empowerment, supervisor and coworker incivility, and burnout on three employee retention outcomes: job satisfaction, organizational commitment, and turnover intentions in a sample of 612 Canadian staff nurses. Hierarchical multiple linear regression analyses revealed that empowerment, workplace incivility, and burnout explained significant variance in all three retention factors: job satisfaction (R(2) = 0.46), organizational commitment (R(2) = 0.29) and turnover intentions (R(2) = 0.28). Empowerment, supervisor incivility, and cynicism most strongly predicted job dissatisfaction and low commitment (P job satisfaction, organizational commitment, and turnover intentions. Managerial strategies that empower nurses for professional practice may be helpful in preventing workplace incivility, and ultimately, burnout.

    The cell phone is an indispensable service facilitator, however, the disposal and recycling of cell phones is a major problem. While the potential life span of a mobile phone, excluding batteries, is over 10 years, most of the users upgrade their phones approximately four times during this period. Cell phone waste is significantly more hazardous than many other municipal wastes as it contains thousands of components made of toxic chemicals and metals like lead, cadmium, chromium, mercury, polyvinyl chlorides (PVC), brominated flame retardants, beryllium, antimony and phthalates. Cell phones also use many expensive rare metals. Since cell phones are made up of plastics, metals, ceramics, and trace other substances, primitive recycling or disposal of cell phone waste to landfills and incinerators creates irreversible environmental damage by polluting water and soil, and contaminating air. In order to minimize releases into the environment and threat to human health, the disposal of cell phones needs to be managed in an environmentally friendly way. This paper discussed a safer method of reducing the generation of syngas and hydrocarbons and metal recovery through the treatment of cell phone wastes by a thermal plasma. The presentation discussed the experiment, with particular reference to sample preparation; experimental set-up; and results four samples with different experimental conditions. It was concluded that the plasma treatment of cell phone waste in reduced condition generates gaseous components such as hydrogen, carbon monoxide, and hydrocarbons which are combustible. Therefore, this system is an energy recovery system that contributes to resource conservation and reduction of climate change gases. 5 refs., 2 tabs., 2 figs.

    Science.gov (United States)

    Kang, Jiyeon; Jeong, Yeon Jin; Kong, Kyoung Ran

    2018-02-01

    This qualitative study aimed to explore the experience of incivility among nursing students. Sixteen nursing students who had experienced incivility during their clinical placement were invited for one-on-one interviews until the point of theoretical saturation. The grounded theory approach of Corbin and Strauss was adopted to analyze transcribed interview contents. Incivility occurred in the context of a hierarchical organizational culture, due to nursing students' position as outsiders, non-systematic clinical education, and poor nursing work environment. The experience of incivility was identified as "being mistreated as a marginal person," and nursing students responded to this phenomenon in the following three steps: reality shock, passive action, and submissive acceptance. This process caused students to lose self-esteem and undergo role conflict. Furthermore, nursing students' experience of incivility could eventually lead to workplace bullying in nurses. The results of this study suggest that nursing students' experience of incivility can be a process that threatens their identity. It is necessary to develop educational programs and provide appropriate counseling services so that nursing students can actively cope with the incivility. In addition, institutional plans are needed to ensure safe and supportive clinical learning environments. © 2018 Korean Society of Nursing Science.

    Previous research suggests that anticipation of incoming phone calls or messages and impulsivity are significantly associated with motor vehicle crash. We took a more explanative approach to investigate a conceptual model regarding the direct and indirect effect of compulsive cell phone use and impulsive personality traits on crash risk. We recruited a sample of 307 undergraduate college students to complete an online survey that included measures of cell phone use, impulsivity, and history of motor vehicle crash. Using a structural equation model, we examined the direct and indirect relationships between factors of the Cell Phone Overuse Scale-II (CPOS-II), impulsivity, in-vehicle phone use, and severity and frequency of previous motor vehicle crash. Self-reported miles driven per week and year in college were included as covariates in the model. Our findings suggest that anticipation of incoming communication has a direct association with greater in-vehicle phone use, but was not directly or indirectly associated with increasing risk of previous motor vehicle crash. Of the three latent factors comprising the CPOS-II, only anticipation was significantly associated with elevated cell phone use while driving. Greater impulsivity and use of in-vehicle cell phone use while driving were directly and significantly associated with greater risk of motor vehicle crash. Anticipation of incoming cellular contacts (calls or texts) is associated with greater in-vehicle phone use, while greater in-vehicle cell phone use and impulsive traits are associated with elevated risk of motor vehicle crashes.

    Use of cell phones in the general population has become increasingly commonplace. The distracting effects of cell phones among automobile drivers are well established, and legislation prohibits the use of handheld cell phones while driving in several states. Recent research has focused on the similar distracting effects of cell phones in the pedestrian population. In this report, an older gentleman suffered extensive facial trauma requiring surgery as a direct effect of cell phone use at the time the trauma occurred. This case highlights the role that portable electronic devices can play as a cause of ocular trauma.

    A team composed of Rick Pratt, Dave Puczyki, Kyle Bunch, Ryan Slaugh, Morris Good, and Doug McMakin teamed together to attempt to exploit cellular telephone features and detect if a person was carrying a cellular telephone into a Limited Area. The cell phone’s electromagnetic properties were measured, analyzed, and tested in over 10 different ways to determine if an exploitable signature exists. The method that appears to have the most potential for success without adding an external tag is to measure the RF spectrum, not in the cell phone band, but between 240 and 400MHz. Figures 1- 7 show the detected signal levels from cell phones from three different manufacturers.

    2015-06-01

    Academic incivility is a serious challenge for nursing education, which needs to be empirically measured and fully addressed. A convenience sample of nursing faculty and students from 20 schools of nursing in the United States participated in a mixed-methods study to test the psychometric properties of the Incivility in Nursing Education-Revised (INE-R) Survey. A factor analysis and other reliability analyses support the use of the INE-R as a valid and reliable measurement of student and faculty perceptions of incivility in nursing education. The INE-R is a psychometrically sound instrument to measure faculty and student perceptions of incivility; to examine differences regarding levels of nursing education, program type, gender, age, and ethnicity; to compare perceptions of incivility between and among adjunct, clinical, teaching, and research faculty; and to conduct pre- and postassessments of the perceived levels of faculty and student incivility in nursing programs to inform evidence-based interventions.

    Shell Canada demands that workers do not operate telecommunication systems while operating a motor vehicle for company business, with the exception of short acknowledgment conversations. This power point presentation advised of the dangers of using cell phones while driving. Cell phone use while driving is considered to be mentally demanding as well as contributing to slower reaction times to hazards and reducing driving field of view. Research has indicated that drivers visualize an image of the person being spoken to, in addition to thinking about issues being discussed. Statistics from the United Kingdom reveal that drivers engaged in cell phone conversations are 4 times more likely to crash than other drivers, and take risks comparable to alcohol impaired driving, as well as showing significantly poorer driving performance. Various types of driver distractions were presented. A comparison between radio and cell phones was presented. It was suggested that drivers should not take a phone call while driving alone, and in an emergency, should pull off the road to receive or send phone calls. It was also suggested that callers should ask if a person is driving, and end a conversation if they suspect the person is driving. tabs, figs.

    The objective of the present retrospective study was to report our experience concerning the effects of cell phone usage on semen parameters. We examined 2110 men attending our infertility clinic from 1993 to October 2007. Semen analysis was performed in all patients. Serum free testosterone (T), follicle stimulating hormone (FSH), luteinising hormone (LH) and prolactin (PRL) were collected from all patients. The information on cell phone use of the patients was recorded and the subjects were divided into two groups according to their cell phone use: group A: cell phone use (n = 991); group B: no use (n = 1119). Significant difference was observed in sperm morphology between the two groups. In the patients of group A, 68.0% of the spermatozoa featured a pathological morphology compared to only 58.1% in the subjects of group B. Patients with cell phone usage showed significantly higher T and lower LH levels than those who did not use cell phone. No significant difference between the two groups was observed regarding FSH and PRL values. Our results showed that cell phone use negatively affects sperm quality in men. Further studies with a careful design are needed to determine the effect of cell phone use on male fertility. © 2011 Blackwell Verlag GmbH.

    Today, the cell phone is the most widespread technology globally. However, the outcome of cell-phone radiofrequency on head and neck cancer progression has not yet been explored. The chorioallantoic membrane (CAM) and human head and neck cancer cell lines, FaDu and SCC25, were used to explore the outcome of cell-phone radiofrequency on angiogenesis, cell invasion, and colony formation of head and neck cancer cells, respectively. Western blot analysis was used to investigate the impact of the cell phone on the regulation of E-cadherin and Erk1/Erk2 genes. Our data revealed that cell-phone radiofrequency promotes angiogenesis of the CAM. In addition, the cell phone enhances cell invasion and colony formation of human head and neck cancer cells; this is accompanied by a downregulation of E-cadherin expression. More significantly, we found that the cell phone can activate Erk1/Erk2 in our experimental models. Our investigation reveals that cell-phone radiofrequency could enhance head and neck cancer by stimulating angiogenesis and cell invasion via Erk1/Erk2 activation. © 2018 Wiley Periodicals, Inc.

  10. Management of Nursing Workplace Incivility in the Health Care Settings: A Systematic Review.

    Armstrong, Nancy

    2018-05-01

    Workplace incivility is a well-documented issue in nursing in the health care setting. It has the potential to cause emotional and physical distress in victims and potentially affects the quality of care provided. The purpose of this study was to critique and summarize the most recent, available evidence related to interventions in assisting nursing staff working in health care settings in managing incivility. This systematic review of literature yielded 10 studies meeting the criteria. The studies were mostly identified as lower quality research. Despite the lower quality of research, the collection of evidence suggests the use of a combination of educational training about workplace incivility, training about effective responses to uncivil workplace behaviors, and active learning activities to practice newly learned communication skills, in assisting nurses in improving their ability to manage incivility in the workplace.

    Full Text Available Evidence is growing that forms of incivility-e.g. aggressive and disrespectful behaviors, harassment, hate speech and outrageous claims-are spreading in the population of social networking sites' (SNS users. Online social networks such as Facebook allow users to regularly interact with known and unknown others, who can behave either politely or rudely. This leads individuals not only to learn and adopt successful strategies for using the site, but also to condition their own behavior on that of others. Using a mean field approach, we define anevolutionary game framework to analyse the dynamics of civil and uncivil ways of interaction in online social networks and their consequences for collective welfare. Agents can choose to interact with others-politely or rudely-in SNS, or to opt out from online social networks to protect themselves from incivility. We find that, when the initial share of the population of polite users reaches a critical level, civility becomes generalized if its payoff increases more than that of incivility with the spreading of politeness in online interactions. Otherwise, the spreading of self-protective behaviors to cope with online incivility can lead the economyto non-socially optimal stationary states. JEL Codes: C61, C73, D85, O33, Z13.

    Kim, Ji-Soo

    2018-06-01

    During clinical practice, nursing students develop their professional role and internalize the values of the nursing profession. Unfortunately, it also often exposes them uncivil behaviors from nurses. To identify the relationship between incivility experiences and nursing professional values, and investigate the potential moderating effects of coping strategies in this relationship. This was a descriptive, cross-sectional study. Data were collected from 203 nursing students using questionnaires. The questionnaire comprised sections assessing participant characteristics, incivility experiences, coping strategies, and nursing professional values. Multiple regression analysis was used to identify the relationship between incivility experiences and nursing professional values, as well as the interaction effect of incivility experiences and coping strategies on nursing professional values. Incivility experiences were negatively related to nursing professional values. Furthermore, seeking support moderated the relationship between incivility experiences and nursing professional values. In other words, as incivility experiences increased, nursing students who used more seeking social support tended to have stronger nursing professional values than did those who used this coping strategy less. To improve the nursing professional values of nursing students, educators must inform nursing managers when nurses direct uncivil behaviors towards students. Educators should also listen to students' experiences, support them emotionally, and encourage students to engage in seeking social support. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Due to the cost-effective nature of wireless networks, the number of cell phones used around the world has increased significantly. However, a major problem of this technology is the generation of a great deal of complex electronics wastes, such as cell phones. The typical average life of a cell phone is around 2 years. Therefore, inexpensive recycling techniques must be developed for valuable resources such as real metals and plastics used in cell phones. Thermal plasma has been used for many different waste treatments since it has the capability to detoxify waste by-products. This paper presented a preliminary investigation for cell phone recycling by a thermal plasma technology. Recyclable resource material was identified by neutron activation analyses. Then, the cell phone waste was first crashed and treated by Ar twin torch plasmas to remove the majority of organic materials. The paper described the experimental apparatus and results. It was concluded that styrene (C{sub 8}H{sub 8}) and benzene (C{sub 6}H{sub 6}O) may be two major by-products in on-line by-products gas. The molecule becomes a much heavier by-product gas after cooling down. 6 refs., 6 figs.

    This study extends the stress literature by exploring the relationship between family incivility and job performance. We examine whether psychological distress mediates the link between family incivility and job performance. We also investigate how core self-evaluation might moderate this mediated relationship. Data from a 2-wave study indicate that psychological distress mediates the relationship between family incivility and job performance. In addition, core self-evaluation moderates the relationship between family incivility and psychological distress but not the relationship between psychological distress and job performance. The results hold while controlling for general job stress, family-to-work conflict, and work-to-family conflict. The findings suggest that family incivility is linked to poor performance at work, and psychological distress and core self-evaluation are key mechanisms in the relationship.

    Physical activity (PA) diaries reduce the recall error inherent in self-reported PA but are burdensome. The purpose of this study was to compare a cell phone-based diary with a paper diary and examine the reliability and validity of the cell phone diary. In a pilot study, 25 women and 23 men, age 45-65 yr, completed cell phone and paper PA diaries 4 d·wk(-1) for three consecutive weeks and a user satisfaction survey. In the subsequent validation study, 623 middle-age participants (52.5% women) were asked to complete the cell phone diary and wear an accelerometer for two 7-d periods, approximately 6 months apart. They also completed two PA questionnaires. Fitness, body mass index, and percent body fat were obtained as indirect validation criteria. Estimates of PA from the cell phone and paper diaries were similar (mean within person difference = -43.8 MET·min·d(-1) of total PA, SD = 360, P = 0.49, 7.4 min·d(-1) of moderate-vigorous PA, SD = 66, P = 0.53). Users preferred the cell phone diary over the paper diary (59.6% vs 35.4%). In the subsequent study, intraclass correlations for the cell phone diary ranged from 0.55 for light PA to 0.63 for vigorous PA. Although PA estimates from the cell phone diary were generally significantly higher than those from the accelerometer and the questionnaires, correlations for moderate and vigorous PA were moderate (ρ = 0.25-0.59 with the questionnaires and 0.27-0.35 with the accelerometer). The correlations between the cell phone diary and the indirect validation criteria were generally in the expected direction and of moderate magnitude. A cell phone-based PA diary is equivalent to a paper diary, acceptable to users, and a relatively reliable and valid approach to self-reported PA.

    Early adolescents are using cell phones with increasing frequency. Cell phones are known to distract motor vehicle drivers to the point that their safety is jeopardized, but it is unclear if cell phones might also distract child pedestrians. This study was designed to examine the influence of talking on a cell phone for pediatric pedestrian injury risk. Seventy-seven children aged 10 to 11 years old completed simulated road crossings in an immersive, interactive virtual pedestrian environment. In a within-subjects design, children crossed the virtual street 6 times while undistracted and 6 times while distracted by a cell phone conversation with an unfamiliar research assistant. Participants also completed several other experimental tasks hypothesized to predict the impact of distraction while crossing the street and talking on a cell phone. Children's pedestrian safety was compromised when distracted by a cell phone conversation. While distracted, children were less attentive to traffic; left less safe time between their crossing and the next arriving vehicle; experienced more collisions and close calls with oncoming traffic; and waited longer before beginning to cross the street. Analyses testing experience using a cell phone and experience as a pedestrian yielded few significant results, suggesting that distraction on the cell phone might affect children's pedestrian safety no matter what their experience level. There was some indication that younger children and children who are less attentive and more oppositional may be slightly more susceptible to distraction while talking on the cell phone than older, more attentive, and less oppositional children. Our results suggest that cell phones distract preadolescent children while crossing streets.

    2016-12-01

    In this study, we developed and tested the psychometric properties of a translated and culturally adapted Korean version of the Incivility in Nursing Education-Revised (INE-R) survey. Using a cross-sectional design, the INE-R was administered to a convenience sample of 284 students enrolled in three Korean nursing colleges. Descriptive statistics were calculated for 24 student and 24 faculty incivility behavior items. Underlying factor structure was examined using exploratory and confirmatory factor analyses, and model fit was assessed using chi-square goodness-of-fit and other fit indices. For student incivility items, a four-factor model provided the best fit for the data, while a two-factor model provided the best fit for faculty incivility items. Overall reliability of the INE-R for student and faculty incivility behavior was estimated as α = 0.94 and 0.96, respectively. The Korean version of the INE-R is a reliable measure for assessing perceptions of student and faculty incivility among Korean nursing students. © 2016 John Wiley & Sons Australia, Ltd.

    2018-05-01

    Although cell phone use and Internet access via cell phone is not marked by racial disparities, little is known about how cell phone use relates to blood pressure and health information seeking behaviors. The purposes of this study were to (a) describe Internet activities, cell phone use, and information seeking; (b) determine differences in blood pressure and information seeking between cell phone information seekers and nonseekers; and (c) examine cell phone information seeking as a predictor of blood pressure in African American women. Participants ( N = 147) completed a survey and had their blood pressure measured. Independent-sample t tests showed a significant difference in systolic blood pressure in cell phone information seekers and nonseekers. Linear regression revealed cell phone information seeking as an independent predictor of systolic blood pressure, despite confounders. It is possible that cell phone information seekers were using health information to make decisions about self-management of blood pressure.

    Full Text Available A qualitative phenomenological study was conducted on the consequences of cell phone use while operating a vehicle. We discussed why talking and texting on cell phones are so popular through the analysis of our interviews with police officers, driving instructors, and parents of teens and young adults. The participants came from central, northeastern, northwestern, and southeastern Connecticut. All had exposure with respect to the effects of cell phone usage problem. The study reached a point of theoretical saturation or redundancy by which the analysis no longer resulted in new themes. We concluded that the discoveries revealed the necessity for education, expansion of technology, and additional driver education preparation, which may provide a path for leadership to help solve the problem.

  8. Here today but not gone tomorrow: incivility affects after-work and next-day recovery.

    Nicholson, Tahnee; Griffin, Barbara

    2015-04-01

    This study examined the relation between daily incivility and afterwork recovery, hypothesizing that workplace incivility would have a negative effect on situational wellbeing, afterwork recovery experiences (psychological detachment and relaxation) and next-morning recovery level. Daily surveys were completed on 5 consecutive workdays by 175 employees in the legal industry. Multilevel analyses controlling for the daily number of hours worked showed that day-level incivility was negatively related to afterwork situational wellbeing and psychological detachment, but not to relaxation. Incivility experienced on 1 day also predicted recovery level the following morning. Results emphasize the ongoing impact of rudeness and disrespect in the workplace on employee wellbeing and offer an explanation for the long-term negative outcomes of what is typically thought of as a less severe workplace stressor.

  10. The development and validation of the Incivility from Customers Scale.

    Science.gov (United States)

    Wilson, Nicole L; Holmvall, Camilla M

    2013-07-01

    Scant research has examined customers as sources of workplace incivility, despite evidence suggesting that mistreatment is more common from organizational outsiders, including customers, than from organizational members (Grandey, Kern, & Frone, 2007; Schat & Kelloway, 2005). As an important step in extending the literature on customer incivility, we conducted two studies to develop and validate a measure of this construct. Study 1 used focus groups of retail and restaurant employees (n = 30) to elicit a list of uncivil customer behaviors, based on which we wrote initial scale items. Study 2 used a correlational survey design (n = 439) to pare down the number of scale items to 10 and to garner reliability and validity evidence for the scale. Exploratory and confirmatory factor analyses show that the scale is unidimensional and distinguishable from measures of the related, but distinct, constructs of interpersonal justice and psychological aggression from customers. Reliability analyses show that the scale is internally consistent. Significant correlations between the scale and individuals' job satisfaction, turnover intentions, and general and job-specific psychological strain provide evidence of criterion-related validity. Hierarchical regression analyses show that the scale significantly predicts three of four organizational and personal strain outcomes over and above a workplace incivility measure adapted for customer incivility, providing some evidence of incremental validity. Limitations and future research directions are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

  12. Relationship of Near-Crash/Crash Risk to Time Spent on a Cell Phone While Driving.

    The objective of this study was to examine in a naturalistic driving setting the dose-response relationship between cell phone usage while driving and risk of a crash or near crash. How is the increasing use of cell phones by drivers associated with overall near-crash/crash risk (i.e., during driving times both on and off the phone)? Day-to-day driving behavior of 105 volunteer subjects was monitored over a period of 1 year. A random sample was selected comprised of 4 trips from each month that each driver was in the study, and in-vehicle video was used to classify driver behavior. The proportion of driving time spent using a cell phone was estimated for each 3-month period and correlated with overall crash and near-crash rates for each period. Thus, it was possible to test whether changes in an individual driver's cell phone use over time were associated with changes in overall near-crash/crash risk. Drivers in the study spent 11.7% of their driving time interacting with a cell phone, primarily talking on the phone (6.5%) or simply holding the phone in their hand or lap (3.7%). The risk of a near-crash/crash event was approximately 17% higher when the driver was interacting with a cell phone, due primarily to actions of reaching for/answering/dialing, which nearly triples risk (relative risk = 2.84). However, the amount of driving time spent interacting with a cell phone did not affect a driver's overall near-crash/crash risk. Vehicle speeds within 6 s of the beginning of each call on average were 5-6 mph lower than speeds at other times. Results of this naturalistic driving study are consistent with the observation that increasing cell phone use in the general driving population has not led to increased crash rates. Although cell phone use can be distracting and crashes have occurred during this distraction, overall crash rates appear unaffected by changes in the rate of cell phone use, even for individual drivers. Drivers compensate somewhat for the distraction

    Background. Cell-phone usage has increased dramatically over the last decade, along with a rising public concern over the health effects of using this device. The association between cell-phone usage and hypertension has not been examined before. Methods. We analysed data from 21,135 adults aged ≥18 years who participated in the 2008 National Health Interview Survey. Based on reported cell-phone use, participants were categorized as cell-phone nonusers, predominantly landline users, dual users of cell phone and landline, and predominantly cell-phone users. The main outcome of interest was self-reported physician-diagnosed hypertension (n = 6,793). Results. 43.5% of the participants were cell-phone nonusers, while 13.8% were predominantly cell-phone users. We found that cell-phone use was inversely associated with hypertension, independent of age, sex, race/ethnicity, smoking, alcohol consumption, education, body mass index (BMI), and physical activity. Compared to cell-phone nonusers, the multivariable odds ratio (95% confidence interval) of hypertension was 0.86 (0.75-0.98, P trend  =  .005) among predominantly cell-phone users. This inverse association between cell-phone use and hypertension was stronger in women, those aged <60 years, whites, and those with BMI <25 kg/m(2). Conclusion. We found that cell-phone usage was protectively associated with self-reported hypertension in a nationally representative sample of US adults.

    Science.gov (United States)

    Zurbrügg, Lauren; Miner, Kathi N

    2016-01-01

    Scholars have proposed that interpersonal workplace discrimination toward members of oppressed social groups has become covert and subtle rather than overt and explicit and that such experiences lead to negative outcomes for targets. The present study examined this proposition by examining experiences and consequences of workplace incivility-a seemingly harmless form of interpersonal maltreatment-based on gender, sexual orientation, and their intersection. A sample of 1,300 academic faculty (52% male, 86% White) participated in an online survey study assessing their experiences of workplace incivility, job stress, job satisfaction, job identity centrality, and demographics. Results showed that sexual minority women reported the highest levels of workplace incivility. Findings also revealed that women reported lower job satisfaction than men and that heterosexuals reported higher job stress and lower job identity centrality than sexual minorities with higher levels of incivility. Thus, sexual minority status buffered the negative effects of incivility for sexual minorities. These findings point to the resiliency of sexual minorities in the face of interpersonal stressors at work.

    Bullied workers have poor self-reported mental health; monetary costs of bullying exposure are unknown. We tested associations between bullying and health plan claims for mental health diagnoses. We used data from 793 hospital workers who answered questions about bullying in a survey and subscribed to the group health plan. We used two-part models to test associations between types of incivility/bullying and mental health expenditures. Workers experiencing incivility or bullying had greater odds of any mental health claims. Among claimants, unexposed workers spent $792, those experiencing one type of incivility or bullying spent $1,557 (p for difference from unexposed=0.016), those experiencing two types spent $928 (p = 0.503), and those experiencing three types spent $1,446 (p = 0.040). Workplace incivility and bullying may carry monetary costs to employers, which could be controlled through work environment modification.

    2010-07-01

    Despite the known risk, many people talk on a phone while driving. This study explored psychological predictors of cell phone use while driving. College students (final N=69) completed a survey and predicted their driving performance both with and without a simultaneous phone conversation. Their actual performance on a driving simulator was then assessed. Cell phone use reduced performance on the simulation task. Further, perceiving oneself as good at compensating for driving distractions, overestimating one's performance on the driving simulator, and high illusory control predicted more frequent cell phone use while driving in everyday life. Finally, those who talked more frequently on a phone while driving had poorer real-world driving records. These findings suggest illusory control and positive illusions partly explain driver's decisions of whether to use cell phones while driving. Copyright 2010 Elsevier Ltd. All rights reserved.

  8. Geophysical Surveying of Shallow Magnetic Anomalies Using the iPhone Magnetometer

    Science.gov (United States)

    Opdyke, P.; Dudley, C.; Louie, J. N.

    2012-12-01

    This investigation examined whether the 3-axis Hall-effect magnetometer in the Apple iPhone 3GS can function as an effective shallow magnetic survey instrument. The xSensor Pro app from Crossbow Systems allows recoding of all three sensor components along with the GPS location, at a frequency of 1.0, 4.0, 16.0, and 32.0 Hz. If the iPhone proves successful in collecting useful magnetic data, then geophysicists and especially educators would have a new tool for high-density geophysical mapping. No-contract iPhones that can connect with WiFi can be obtained for about $400, allowing deployment of large numbers of instruments. iPhones with the xSensor Pro app surveyed in parallel with an Overhauser GEM system magnetometer (1 nT sensitivity) to test this idea. Anderson Bay, located on the Pyramid Lake Paiute Reservation, provided a rural survey location free from cultural interference. xSensor Pro, logged each component's intensity and the GPS location at a frequency of four measurements per second. Two Overhauser units functioned as a base unit and a roving unit. The roving unit collected total field at set points located with a handheld GPS. Comparing the total field computed from the iPhone components against that collected by the Overhauser establishes the level of anomalies that the iPhone can detect. iPhone total-field measurements commonly vary by 200 nT from point to point, so a spatial-temporal average over 25 seconds produces a smoothed signal for comparison. Preliminary analysis of the iPhone results show that the data do not accurately correlate to the total field collected by the Overhauser for any anomaly of less than 200 nT.

  9. Cell phone use and traffic crash risk: a culpability analysis.

    Asbridge, Mark; Brubacher, Jeff R; Chan, Herbert

    2013-02-01

    The use of a cell phone or communication device while driving is illegal in many jurisdictions, yet evidence evaluating the crash risk associated with cell phone use in naturalistic settings is limited. This article aims to determine whether cell phone use while driving increases motor vehicle crash culpability. Method Drivers involved in crashes where police reported cell phone use (n = 312) and propensity matched drivers (age, sex, suspect alcohol/drug impairment, crash type, date, time of day, geographical location) without cell phone use (n = 936) were drawn from Insurance Corporation of British Columbia Traffic Accident System data. A standardized scoring tool, modified to account for Canadian driving conditions, was used to determine crash culpability from police reports on all drivers from the crashes. The association between crash culpability and cell phone use was determined, with additional subgroup analyses based on crash severity, driver characteristics and type of licence. A comparison of crashes with vs without cell phones revealed an odds ratio of 1.70 (95% confidence interval 1.22-2.36; P = 0.002). This association was consistent after adjustment for matching variables and other covariates. Subgroup analyses demonstrated an association for male drivers, unimpaired drivers, injured and non-injured drivers, and for drivers aged between 26 and 65 years. Crash culpability was found to be significantly associated with cell phone use by drivers, increasing the odds of a culpable crash by 70% compared with drivers who did not use a cell phone. This increased risk was particularly high for middle-aged drivers.

    Fluorescent microscopy and flow cytometry are widely used tools in biomedical sciences. Cost-effective translation of these technologies to remote and resource-limited environments could create new opportunities especially for telemedicine applications. Toward this direction, here we demonstrate the integration of imaging cytometry and fluorescent microscopy on a cell phone using a compact, lightweight, and cost-effective optofluidic attachment. In this cell-phone-based optofluidic imaging cytometry platform, fluorescently labeled particles or cells of interest are continuously delivered to our imaging volume through a disposable microfluidic channel that is positioned above the existing camera unit of the cell phone. The same microfluidic device also acts as a multilayered optofluidic waveguide and efficiently guides our excitation light, which is butt-coupled from the side facets of our microfluidic channel using inexpensive light-emitting diodes. Since the excitation of the sample volume occurs through guided waves that propagate perpendicular to the detection path, our cell-phone camera can record fluorescent movies of the specimens as they are flowing through the microchannel. The digital frames of these fluorescent movies are then rapidly processed to quantify the count and the density of the labeled particles/cells within the target solution of interest. We tested the performance of our cell-phone-based imaging cytometer by measuring the density of white blood cells in human blood samples, which provided a decent match to a commercially available hematology analyzer. We further characterized the imaging quality of the same platform to demonstrate a spatial resolution of ~2 μm. This cell-phone-enabled optofluidic imaging flow cytometer could especially be useful for rapid and sensitive imaging of bodily fluids for conducting various cell counts (e.g., toward monitoring of HIV+ patients) or rare cell analysis as well as for screening of water quality in

    2011-09-01

    Cell phone use in the U.S. has increased dramatically over the past decade and text messaging among adults is now mainstream. In professions such as perfusion, where clinical vigilance is essential to patient care, the potential distraction of cell phones may be especially problematic. However, the extent of this as an issue is currently unknown. Therefore, the purpose of this study was to (1) determine the frequency of cell phone use in the perfusion community, and (2) to identify concerns and opinions among perfusionists regarding cell phone use. In October 2010, a link to a 19-question survey (surveymonkey.com) was posted on the AmSECT (PerfList) and Perfusion.com (PerfMail) forums. There were 439 respondents. Demographic distribution is as follows; Chief Perfusionist (30.5%), Staff Perfusionist (62.0%), and Other (7.5%), with age ranges of 20-30 years (14.2%), 30-40 years (26.5%), 40-50 years (26.7%), 50-60 years (26.7%), >60 years (5.9%). The use of a cell phone during the performance of cardiopulmonary bypass (CPB) was reported by 55.6% of perfusionists. Sending text messages while performing CPB was acknowledged by 49.2%, with clear generational differences detected when cross-referenced with age groups. For smart phone features, perfusionists report having accessed e-mail (21%), used the internet (15.1%), or have checked/posted on social networking sites (3.1%) while performing CPB. Safety concerns were expressed by 78.3% who believe that cell phones can introduce a potentially significant safety risk to patients. Speaking on a cell phone and text messaging during CPB are regarded as "always an unsafe practice" by 42.3% and 51.7% of respondents, respectively. Personal distraction by cell phone use that negatively affected performance was admitted by 7.3%, whereas witnessing another perfusionist distracted with phone/text while on CPB was acknowledged by 33.7% of respondents. This survey suggests that the majority of perfusionists believe cell phones raise

    Multitasking diminishes the self-awareness of performance that is often essential for self-regulation and self-knowledge. Participants drove in a simulator while either talking or not talking on a hands-free cell phone. Following previous research, participants who talked on a cell phone made more serious driving errors than control participants who did not use a phone while driving. Control participants' assessments of the safeness of their driving and general ability to drive safely while distracted were negatively correlated with the actual number of errors made when they were driving. By contrast, cell-phone participants' assessments of the safeness of their driving and confidence in their driving abilities were uncorrelated with their actual errors. Thus, talking on a cell phone not only diminished the safeness of participants' driving, it diminished their awareness of the safeness of their driving.

    We demonstrate a compact and cost-effective imaging cytometry platform installed on a cell-phone for the measurement of the density of red and white blood cells as well as hemoglobin concentration in human blood samples. Fluorescent and bright-field images of blood samples are captured using separate optical attachments to the cell-phone and are rapidly processed through a custom-developed smart application running on the phone for counting of blood cells and determining hemoglobin density. We evaluated the performance of this cell-phone based blood analysis platform using anonymous human blood samples and achieved comparable results to a standard bench-top hematology analyser. Test results can either be stored on the cell-phone memory or be transmitted to a central server, providing remote diagnosis opportunities even in field settings.

    Building on the approach/inhibition theory of power and the situated focus theory of power, we examine the roles of positional and personal power on altruism and incivility in workplace dyads. Results from a field study in daycare centers showed that legitimate power (a dimension of positional power) was positively associated with incivility. In contrast, personal power-referent power and expert power-was positively associated altruism and was negatively associated with incivility. Referent power was a stronger predictor of both altruism and incivility for individuals with low humility than those with high humility. Coercive power was a stronger predictor of incivility for individuals with high humility than those with low humility.

    2011-01-01

    Results. 43.5% of the participants were cell-phone nonusers, while 13.8% were predominantly cell-phone users. We found that cell-phone use was inversely associated with hypertension, independent of age, sex, race/ethnicity, smoking, alcohol consumption, education, body mass index (BMI, and physical activity. Compared to cell-phone nonusers, the multivariable odds ratio (95% confidence interval of hypertension was 0.86 (0.75–0.98, P trend  =  .005 among predominantly cell-phone users. This inverse association between cell-phone use and hypertension was stronger in women, those aged <60 years, whites, and those with BMI <25 kg/m2. Conclusion. We found that cell-phone usage was protectively associated with self-reported hypertension in a nationally representative sample of US adults.

    This study had three objectives: (1) to investigate the impact of workplace incivility on job burn-out of new nursing staff, (2) to verify the partial mediating role of anxiety in the relationship between workplace incivility and job burn-out, (3) to examine the resilience moderating the relations between workplace incivility and job burn-out. A cross-sectional online survey was conducted in May 2016 in China. The survey was conducted in 54 cities across 29 provinces of China. A total of 903 participants were invited. Ultimately, 696 new nurses (analysis, Pearson's correlation coefficient and multiple linear regression analysis. The findings showed that workplace incivility was positively correlated with anxiety (r=0.371, pjob burn-out (r=0.238, pjob burn-out (β = 0.240, pjob burn-out. Experience of workplace incivility by new nurses would likely generate anxiety in the victims. Further, the increased anxiety state could elevate their level of job burn-out. New nurses with high levels of resilience could buffer the negative influence of workplace incivility by using a positive coping style. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Previous research has found that there are certain personality characteristics that predict whether one is likely to become a target of workplace mistreatment, and that these characteristics provoke such behavior (Milam, Spitzmüller, & Penney, 2009. The present paper aims to replicate and expand Milam et al.’s paper by looking at workplace incivility in two parts of the world, the United States and Romania, and two types of sources (self and coworker to see if this phenomenon is uniquely American, or if it is present in another, very different culture. Our findings indicate that in both countries, low levels of agreeableness and high levels of neuroticism are associated with individuals’ reports of receiving higher levels of workplace incivility than their counterparts, and that from the coworkers’ perspectives, this incivility is provoked by the targets of the mistreatment.

    2013-04-01

    Distracted driving has become an important public health concern. However, little is known about the predictors of this health-risking behavior. One overlooked risk factor for distracted driving is the perceived attachment that one feels toward his or her phone. Prior research has suggested that individuals develop bonds toward objects, and qualitative research suggests that the bond between young drivers and their phones can be strong. It follows that individuals who perceive a strong attachment to their phone would be more likely to use it, even when driving. In a nationally representative sample of young drivers (17-28 years), participants (n = 1,006) completed a survey about driving behaviors and phone use. Risk perception surrounding cell phone use while driving and perceived attachment to one's phone were assessed by administering factor-analytically derived scales that were created as part of a larger project. Attachment toward one's phone predicted the proportion of trips in which a participant reported using their cell phone while driving, beyond that accounted for by risk perception and overall phone use. Further, attachment predicted self-reported distracted driving behaviors, such as the use of social media while driving. Attachment to one's phone may be an important but overlooked risk factor for the engagement of potentially health-risking driving behaviors. Understanding that phone attachment may adversely affect driving behaviors has the potential to inform prevention and intervention efforts designed to reduce distracted driving behaviors, especially in young drivers. 2013 APA, all rights reserved

    Modern cell phones are a ubiquitous resource with a residual capacity to accommodate chemical sensing and biosensing capabilities. From the different approaches explored to capitalize on such resource, the use of autonomous disposable lab-on-a-chip (LOC) devices-conceived as only accessories to complement cell phones-underscores the possibility to entirely retain cell phones' ubiquity for distributed biosensing. The technology and principles exploited for autonomous LOC devices are here selected and reviewed focusing on their potential to serve cell phone readout configurations. Together with this requirement, the central aspects of cell phones' resources that determine their potential for analytical detection are examined. The conversion of these LOC concepts into universal architectures that are readable on unaccessorized phones is discussed within this context. Copyright © 2015 Elsevier B.V. All rights reserved.

    2016-01-01

    This study examined the association between cell phone use, including minutes spent talking and number of text messages sent, and two measures of children’s reading proficiency — tests of word decoding and reading comprehension — in the United States. Data were drawn from the Child Development Supplement to the Panel Study of Income Dynamics, a nationally representative survey of 1,147 children 10–18 in 2009. Children whose parents were better educated, who had higher family incomes, who had fewer siblings, and who lived in urban areas were more likely to own or share a cell phone. Among those with access to a phone, children who spent more time talking on the phone were less proficient at word decoding, whereas children who spent more time sending text messages had greater reading comprehension. Although girls spent more time texting than did boys, there were no gender differences in the association between time spent talking or number of text messages sent with achievement. In spite of racial/ethnic differences in cell phone use levels, there were no racial/ethnic differences in the association between cell phone use and reading proficiency. PMID:27683624

  11. Applying image quality in cell phone cameras: lens distortion

    Science.gov (United States)

    Baxter, Donald; Goma, Sergio R.; Aleksic, Milivoje

    2009-01-01

    This paper describes the framework used in one of the pilot studies run under the I3A CPIQ initiative to quantify overall image quality in cell-phone cameras. The framework is based on a multivariate formalism which tries to predict overall image quality from individual image quality attributes and was validated in a CPIQ pilot program. The pilot study focuses on image quality distortions introduced in the optical path of a cell-phone camera, which may or may not be corrected in the image processing path. The assumption is that the captured image used is JPEG compressed and the cellphone camera is set to 'auto' mode. As the used framework requires that the individual attributes to be relatively perceptually orthogonal, in the pilot study, the attributes used are lens geometric distortion (LGD) and lateral chromatic aberrations (LCA). The goal of this paper is to present the framework of this pilot project starting with the definition of the individual attributes, up to their quantification in JNDs of quality, a requirement of the multivariate formalism, therefore both objective and subjective evaluations were used. A major distinction in the objective part from the 'DSC imaging world' is that the LCA/LGD distortions found in cell-phone cameras, rarely exhibit radial behavior, therefore a radial mapping/modeling cannot be used in this case.

    Language skills are essential for education and economic development. Many countries (especially in Africa) have more than one official language and even more unofficial languages. Being able to express oneself effectively in the written word is required for tertiary education. Unfortunately, cell phones are often blamed for the degradation of language skills. There have been many studies blaming cell phone usage and instant messaging as being responsible for the the lack of language skills of children, teenagers, and young adults. Hadeda is a facility where teachers and parents can create spelling lists for pupils and children using either a cell phone or an internet based workstation. Hadeda then generates a fun and enjoyable cell phone midlet (computer program) which pupils and children can download onto their personal cell phone. Hadeda pronounces the words with electronic voices and the pupils and children can then practice their spelling on a medium they enjoy.

    The public awareness about cell phone safety increased greatly in the last few years as various reports of potential adverse health effects on humans exposed to radiations emitted from cellular phones were published. The aim of the study was to assess the effect of long term cell phone exposure on physiological and hematological parameters along with its impact on serum lipid profiles and a single call effect on heart rate, blood pressure and SpO2(%) of healthy male medical students. The students were divided into two groups, group I (n=22, age 20.63 +/- 1.17 yrs) comprising first year medical students who were never exposed to cell phones at the time of this study and group II (n=35, age 22.00 +/- 1.56 yrs) consists of final year (fourth year) male medical students who were using cell phone for more than four years before this study. The results showed no significant differences the groups in basal heart rate, systolic blood pressure, SpO2(%), or various hematologic parameters. Acute exposure (single call of cell phone with 900 MHz for 1 minute) in both groups showed a significant increase in peak heart rate in group II as compared with group I and a significant decrease in peak SpO2 (%) in group I as compared with group II. Serum total cholesterol, VLDL-cholesterol, and triglycerides concentration were significantly higher in group II (long term cell phone exposed) than in group I, suggesting a mild alteration of lipid profile among group II subjects.

    2011-12-01

    Cell phone use has become nearly ubiquitous among adolescents in the United States. Despite the potential for cell phones to facilitate intervention, research, and care for homeless youth, no data exists to date on cell phone use among this population. In 2009, a survey of cell phone use was conducted among a non-probability sample of 169 homeless youth in Los Angeles, CA. Levels of ownership and use, instrumental uses (connecting to case workers, employers) and patterns of connecting to various network types were assessed (family, home-based peers, street-based peers). Differences in socio-demographic characteristics and cell phone ownership were assessed via t test and chi-square statistics. Sixty-two percent of homeless youth own a cell phone; 40% have a working phone. Seventeen percent used their phone to call a case manager, 36% to call either a potential or current employer. Fifty-one percent of youth connected with home-based peers on the phone and 41% connected to parents. Cell phones present new opportunities for intervention research, connecting homeless youth to family and home-based peers who can be sources of social support in times of need. Moreover, cell phones provide researchers and providers with new avenues to maintain connections with these highly transient youth.

    Children today are exposed to cell phones early in life, and may be at the greatest risk if exposure is harmful to health. We investigated associations between cell phone exposures and headaches in children. The Danish National Birth Cohort enrolled pregnant women between 1996 and 2002. When their children reached age seven years, mothers completed a questionnaire regarding the child's health, behaviors, and exposures. We used multivariable adjusted models to relate prenatal only, postnatal only, or both prenatal and postnatal cell phone exposure to whether the child had migraines and headache-related symptoms. Our analyses included data from 52,680 children. Children with cell phone exposure had higher odds of migraines and headache-related symptoms than children with no exposure. The odds ratio for migraines was 1.30 (95% confidence interval: 1.01-1.68) and for headache-related symptoms was 1.32 (95% confidence interval: 1.23-1.40) for children with both prenatal and postnatal exposure. In this study, cell phone exposures were associated with headaches in children, but the associations may not be causal given the potential for uncontrolled confounding and misclassification in observational studies such as this. However, given the widespread use of cell phones, if a causal effect exists it would have great public health impact.

    There is limited research exploring telephone intervention for psychiatric clients; no studies specific to cell phone use have been conducted. This pilot study examined the feasibility and acceptability of cell phone use in individuals with schizophrenia spectrum disorders (SSDs). Ten outpatients with SSDs were provided with previously activated cell phones for 5 months; trained nurses contacted participants weekly. Seven participants completed the 5-month follow-up period. A minority of participants reported difficulty retrieving messages and answering or charging their phone. These preliminary findings indicate the majority of individuals with SSDs are willing to use this method of communication and are able to do so with few problems. Possible barriers to the use of cell phones with this group include lifestyle factors and poor decision making. Future investigations should examine the use of cell phone access to foster personal safety, gain a sense of connectedness to others, and enhance quality of life.

    Cell phones are the primary communication tool in our institution. There are no restrictions on their use in the operating rooms. The goal of this study was to evaluate the extent of cell phone use in the operating rooms during elective surgery and to evaluate whether they cause staff distractions. The following data on cell phone use were recorded anonymously: number of incoming and outgoing cell phone calls, duration of cell phone calls and their content (patient related, work related, private), who was distracted by the cell phone calls, and duration of distractions. We made observations during 52 surgeries. There were 205 cell phone calls, 197 (96.1%; median, 3 per surgery; interquartile range, 2-5) incoming and 8 (3.9%) outgoing. Incoming calls were answered on 110 (55.8%) of 197 (median, 2; interquartile range, 1-3) occasions. The mean duration of incoming calls (64 ± 40 seconds) was shorter than those of the outgoing calls (137 ± 242 seconds, P cell phone calls in the operating rooms during elective surgery was lower than expected and caused short-lived distractions mainly to the operating surgeons. We recommend that operating surgeons turn off their cell phones before surgery.

    Full Text Available The study objective was to evaluate the feasibility of interviews by cell phone as a complement to interviews by landline to estimate risk and protection factors for chronic non-communicable diseases. Adult cell phone users were evaluated by random digit dialing. Questions asked were: age, sex, education, race, marital status, ownership of landline and cell phones, health condition, weight and height, medical diagnosis of hypertension and diabetes, physical activity, diet, binge drinking and smoking. The estimates were calculated using post-stratification weights. The cell phone interview system showed a reduced capacity to reach elderly and low educated populations. The estimates of the risk and protection factors for chronic non-communicable diseases in cell phone interviews were equal to the estimates obtained by landline phone. Eligibility, success and refusal rates using the cell phone system were lower than those of the landline system, but loss and cost were much higher, suggesting it is unsatisfactory as a complementary method in such a context.

    2014-01-01

    Background and aims: The primary objective of the present study was to investigate which cell-phone activities are associated with cell-phone addiction. No research to date has studied the full-range of cell-phone activities, and their relationship to cell-phone addiction, across male and female cell-phone users. Methods: College undergraduates (N = 164) participated in an online survey. Participants completed the questionnaire as part of their class requirements. The questionnaire took 10 and 15 minutes to complete and contained a measure of cell-phone addiction and questions that asked how much time participants spent daily on 24 cell-phone activities. Results: Findings revealed cell-phone activities that are associated significantly with cell-phone addiction (e.g., Instagram, Pinterest), as well as activities that one might logically assume would be associated with this form of addiction but are not (e.g., Internet use and Gaming). Cell-phone activities that drive cell-phone addiction (CPA) were found to vary considerably across male and female cell-phone users. Although a strong social component drove CPA for both males and females, the specific activities associated with CPA differed markedly. Conclusions: CPA amongst the total sample is largely driven by a desire to connect socially. The activities found to be associated with CPA, however, differed across the sexes. As the functionality of cell-phones continues to expand, addiction to this seemingly indispensable piece of technology becomes an increasingly realistic possibility. Future research must identify the activities that push cell-phone use beyond its “;tipping point” where it crosses the line from a helpful tool to one that undermines our personal well-being and that of others.

    The number of falls and/or accidental injuries associated with cellular phone use during walking is growing rapidly. Understanding the effects of concurrent cell phone use on human gait may help develop safety guidelines for pedestrians. It was shown previously that older adults had more pronounced dual-task interferences than younger adults when concurrent cognitive task required visual information processing. Thus, cell phone use might have greater impact on walking stability in older than in younger adults. This study examined gait stability and variability during a cell phone dialing task (phone) and two classic cognitive tasks, the Paced Auditory Serial Addition Test (PASAT) and Symbol Digit Modalities Test (SDMT). Nine older and seven younger healthy adults walked on a treadmill at four different conditions: walking only, PASAT, phone, and SDMT. We computed short-term local divergence exponent (LDE) of the trunk motion (local stability), dynamic margins of stability (MOS), step spatiotemporal measures, and kinematic variability. Older and younger adults had similar values of short-term LDE during all conditions, indicating that local stability was not affected by the dual-task. Compared to walking only, older and younger adults walked with significantly greater average mediolateral MOS during phone and SDMT conditions but significantly less ankle angle variability during all dual-tasks and less knee angle variability during PASAT. The current findings demonstrate that healthy adults may try to control foot placement and joint kinematics during cell phone use or another cognitive task with a visual component to ensure sufficient dynamic margins of stability and maintain local stability.

    Full Text Available This study aims at investigating Jordanian university undergraduate and graduate students' attitudes towards the learning environment where cell phones are used as learning tools in classroom. To achieve this goal, the researchers distributed two questionnaires among two groups of two different levels of randomly chosen university students at the Faculty of Educational Sciences at Al-al-Bayt University. The first one addresses 30 undergraduate students, 12 male and 18 female. The other addresses 20 graduates, 7 male and 13 female. The study comprised two independent variables, level and gender, as covariates. The findings indicate that undergraduates are more favorable to cell phone environment than graduate students. The study also reveals that cell phone has more influence on male students than on female students.

  15. Gender, Sexual Orientation, and Workplace Incivility: Who Is Most Targeted and Who Is Most Harmed?

    Zurbrügg, Lauren; Miner, Kathi N.

    2016-01-01

    Scholars have proposed that interpersonal workplace discrimination toward members of oppressed social groups has become covert and subtle rather than overt and explicit and that such experiences lead to negative outcomes for targets. The present study examined this proposition by examining experiences and consequences of workplace incivility—a seemingly harmless form of interpersonal maltreatment—based on gender, sexual orientation, and their intersection. A sample of 1,300 academic faculty (52% male, 86% White) participated in an online survey study assessing their experiences of workplace incivility, job stress, job satisfaction, job identity centrality, and demographics. Results showed that sexual minority women reported the highest levels of workplace incivility. Findings also revealed that women reported lower job satisfaction than men and that heterosexuals reported higher job stress and lower job identity centrality than sexual minorities with higher levels of incivility. Thus, sexual minority status buffered the negative effects of incivility for sexual minorities. These findings point to the resiliency of sexual minorities in the face of interpersonal stressors at work. PMID:27199804

    Introduction: The widespread use of cell phone in recent years has raised many questions whether their use is safe to operator who is exposed to Electromagnetic Waves (EMV). Aim To find out the effect of cell phone emitted radiations on the orofacial structures. Materials and Methods To identify suitable literature, an electronic search was performed using Medline, Pubmed and EBSCO host database in December 2016. The search was focused on effect of cell phone on orofacial structures. Among the literature available in English, the screening of the related titles and abstracts was done, and only those articles were selected for full text reading that fulfilled the inclusion criteria. Results The initial literature search resulted in 360 articles out of which only 24 articles fulfilled the inclusion criteria and were included in this systematic review. Conclusion Cell phone emitted radiations had their adverse effect on salivary glands and facial nerves. Studies showed that cell phone emitted radiations had effects on oral mucosal cells and causes changes in salivary flow rate. It was still unclear that cell phone radiations cause tumours of the salivary glands. PMID:28658925

    Full Text Available Abstract Background The development of modern information telecommunication (ITC technology and its use in telemedicine plays an increasingly important role in facilitating access to some diagnostic services even to people living in the most remote areas. However, physical and economical constraints in the access to broad band data-transmission network, still represent a considerable obstacle to the transmission of images for the purpose of tele-pathology. Methods Indifferently using m-phones of different brands, and a variety of microscopic preparations, images were taken without the use of any adaptor simply approaching the lens of the mobile cell phone camera to the ocular of common optical microscopes, and subsequently sent via Multimedia Messaging Services (MMS to distant reference centres for tele-diagnosis. Access to MMS service was reviewed with specific reference to the African information communication technology (ICT market. Results Images of any pathologic preparation could be captured and sent over the mobile phone with an MMS, without being limited by appropriate access to the internet for transmission (i.e. access to broad-band services. The quality of the image was not influenced by the brand or model of the mobile-phone used, but only by its digital resolution, with any resolution above 0.8 megapixel resulting in images sufficient for diagnosis. Access to MMS services is increasingly reaching remote disadvantaged areas. Current penetration of the service in Africa was mapped appearing already available in almost every country, with penetration index varying from 1.5% to 92.2%. Conclusion The use of otherwise already widely available technologies, without any need for adaptors or otherwise additional technology, could significantly increase opportunities and quality diagnostics while lowering costs and considerably increasing connectivity between most isolated laboratories and distant reference center.

    2017-02-01

    Customer service employees tend to react negatively to customer incivility by demonstrating incivility in return, thereby likely reducing customer service quality. Research, however, has yet to uncover precisely what customers do that results in employee incivility. Through transcript and computerized text analysis in a multilevel, multisource, mixed-method field study of customer service events (N = 434 events), we found that employee incivility can occur as a function of customer (a) aggressive words, (b) second-person pronoun use (e.g., you, your), (c) interruptions, and (d) positive emotion words. First, the positive association between customer aggressive words and employee incivility was more pronounced when the verbal aggression included second-person pronouns, which we label targeted aggression. Second, we observed a 2-way interaction between targeted aggression and customer interruptions such that employees demonstrated more incivility when targeted customer verbal aggression was accompanied by more (vs. fewer) interruptions. Third, this 2-way interaction predicting employee incivility was attenuated when customers used positive emotion words. Our results support a resource-based explanation, suggesting that customer verbal aggression consumes employee resources potentially leading to self-regulation failure, whereas positive emotion words from customers can help replenish employee resources that support self-regulation. The present study highlights the advantages of examining what occurs within customer-employee interactions to gain insight into employee reactions to customer incivility.

    The present study examined perceptions of interpersonal injustice as a mediator of the relationship between observed incivility toward women at work and employees' occupational well-being. We also examined gender of the observer as a moderator of these mediational relationships. Using online survey data from 1702 (51% women; 92% White) employees, results showed that perceptions of injustice partially mediated the relationship between observed incivility toward women and job satisfaction, turnover intentions, and organizational trust. Men reported greater perceptions of injustice than did women the more they observed the uncivil treatment of women at work, and the indirect effects of observed incivility toward women on well-being were stronger for men compared to women. Observed incivility toward women also had direct relationships with the occupational well-being outcomes over and above the impact mediated through injustice, particularly for women. Specifically, observing incivility toward female coworkers directly related to lowered job satisfaction and perceptions of safety for female bystanders. In addition, although both male and female bystanders reported heightened turnover intentions and lowered trust in the organization with higher levels of observed incivility toward women, these relationships were stronger for female than male observers. Our findings both replicate and extend past research on vicarious workplace incivility toward women. PMID:27242558

    Accurate reporting of personal dose is required by regulation for hospital personnel that work with radioactive material. Pocket dosimeters are commonly used for monitoring this personal dose. We show that operating a cell phone in the vicinity of a pocket dosimeter can introduce large and erroneous readings of the dosimeter. This note reports a systematic study of this electromagnetic interference. We found that simple practical measures are enough to mitigate this problem, such as increasing the distance between the cell phone and the dosimeter or shielding the dosimeter, while maintaining its sensitivity to ionizing radiation, by placing it inside a common anti-static bag.

    2015-01-01

    Cell phone use while driving (CPWD) has been shown to significantly reduce driver safety. This is a particular concern among young drivers who possess less driving experience and tend to engage in high rates of cell phone use. The present study identified psychological predictors of near accidents related to CPWD among a sample of 385 college student drivers. Participants answered a series of questions regarding their use of a cell phone while driving and completed measures of mindfulness, polychronicity, and intrusive thinking. Students who reported talking on their phone or texting more frequently while driving reported a higher incidence of near accidents related to each behavior. However, after controlling for CPWD, multiple regression analysis indicated that those who reported experiencing more cell phone-related intrusive thoughts also experienced more near accidents. Furthermore, two facets of mindfulness--acting with awareness and nonjudging of inner experience--were negatively associated with near accidents. These findings suggest that individuals who are more aware of the present moment and accepting of their affective responses may better regulate their attention while using a cell phone behind the wheel.

  1. Why drivers use cell phones and support legislation to restrict this practice.

    Science.gov (United States)

    Sanbonmatsu, David M; Strayer, David L; Behrends, Arwen A; Ward, Nathan; Watson, Jason M

    2016-07-01

    The use of cell phones while driving is ubiquitous, particularly in countries where the practice is legal. However, surveys indicate that most drivers favor legislation to limit the use of mobile devices during the operation of a vehicle. A study was conducted to understand this inconsistency between what drivers do and what they advocate for others. Participants completed a survey about their driving attitudes, abilities, and behaviors. Following previous research, drivers reported using cell phones for benefits such as getting work done. The hypocrisy of using cell phones while advocating restrictions appears to stem from differences in the perceived safety risks of self vs. others' use of cell phones. Many if not most drivers believe they can drive safely while using mobile devices. However, they lack confidence in others' ability to drive safely while distracted and believe that others' use of cell phones is dangerous. The threat to public safety of others' usage of mobile devices was one of the strongest independent predictors of support for legislation to restrict cell phone use. Published by Elsevier Ltd.

    The objective of this study was to quantify Melbourne drivers' rates of handheld and hands-free phone use and the driver, vehicle, site, and time characteristics associated with phone use. Additionally, this study sought to examine any change in the prevalence of handheld cell phone use by Melbourne drivers between 2006 and 2009. Observational survey of vehicle drivers at various times of the day and week at 3 sites across metropolitan Melbourne during May 2009. A total of 195 (3.4%) of the 5813 drivers observed were using handheld phones and 81 (1.4%) were using hands-free phones. This represents a significant increase in handheld phone usage rates compared to those found in an earlier study conducted in Melbourne in 2006. Cell phone use was associated with a range of driver, vehicle, site, and time characteristics. Handheld phone users were predominately young or middle-aged drivers who drove cars or 4-wheel-drive vehicles (4WDs), and this activity was more likely to occur in the late afternoon. Use of hands-free phones did not differ significantly across gender, age group, vehicle type, observation site, or time of day; however, use of hands-free phones was higher on weekdays compared to weekends. Despite legislation being in place, drivers' handheld cell phone use is still a major road safety concern, particularly for young and middle-aged drivers. The effectiveness of other strategies for decreasing handheld usage rates, including increased surveillance and tougher penalties, need to be ascertained.

    Background The provision of cell phone numbers and email addresses enhances the accessibility of medical consultations, but can add to the burden of physicians' routine clinical practice and affect their free time. The objective was to assess the attitudes of physicians to providing their telephone number or email address to patients. Methods Primary care physicians in the southern region of Israel completed a structured questionnaire that related to the study objective. Results The study population included 120 primary care physicians with a mean age of 41.2 ± 8.5, 88 of them women (73.3%). Physicians preferred to provide their cell phone number rather than their email address (P = 0.0007). They preferred to answer their cell phones only during the daytime and at predetermined times, but would answer email most hours of the day, including weekends and holidays (P = 0.001). More physicians (79.7%) would have preferred allotted time for email communication than allotted time for cell phone communication (50%). However, they felt that email communication was more likely to lead to miscommunication than telephone calls (P = 0.0001). There were no differences between male and female physicians on the provision of cell phone numbers or email addresses to patients. Older physicians were more prepared to provide cell phone numbers that younger ones (P = 0.039). Conclusions The attitude of participating physicians was to provide their cell phone number or email address to some of their patients, but most of them preferred to give out their cell phone number.

    2013-12-01

    Over the past 15 years, the use of cell phones has increased 8-fold in the United States. Cell phone use has been shown to increase crash risks for drivers, but no systematic analyses have described injuries related to ambulatory cell phone use. The purpose of this study is to describe and quantitate injuries and deaths among persons using cell phones while walking. We searched the National Electronic Injury Surveillance System (NEISS) for emergency department (ED) reports of injuries related to phone use. The cases that returned were screened initially using words that would eliminate cases unlikely to be related to cell phone use and walking, possibly linked to distraction. The resulting cases were randomized and evaluated for consistency with predetermined case definitions by two authors blinded to the dates of the incidents. Cases that were disagreed upon were evaluated in a second screening by both authors for final case determination. National ED visit rates were estimated based on NEISS sampling methods. Annual variations were analyzed using linear regression with a restricted maximum likelihood approach. Our screening process identified 5,754 possible cases that occurred between 2000 and 2011, and 310 were agreed on as cases of cell-phone-induced distraction. The majority of the patients were female (68%) and 40 years of age or younger (54%). The primary mechanism of injury was a fall (72%), and most patients were treated and released from the ED (85%). No patients died from their injuries while they were in the ED. Linear modeling by year revealed a statistically significant increase in distraction injury rates over the years of study (pcell phone use has been increasing. More research is needed to determine the risks associated with walking and talking on a cell phone and to develop strategies for intervention. Cell phone use continues to increase both at home and outdoor environments. The use of smart phones, with their more enticing features, increases

    Immigrants play an increasingly important role in local labor markets. Not only do they grow steadily in number but also in cultural, educational, and skill diversity, underlining the necessity to distinguish between immigrant groups when studying discrimination against immigrants. We examined immigrant employees' subtle discrimination experiences in a representative sample in Switzerland, controlling for dispositional influences. Results showed that mainly members of highly competitive immigrant groups, from immediate neighbor countries, experienced workplace incivility and that these incivility experiences were related to higher likelihoods of perceived discrimination at work. This research confirms recent accounts that successful but disliked groups are particularly likely to experience subtle interpersonal discrimination.

    Although previous studies have linked workplace incivility with various negative outcomes, they mainly focused on the long-term effects of chronic exposure to workplace incivility, whereas targets' short-term reactions to incivility episodes have been largely neglected. Using a daily diary design, the current study examined effects of daily workplace incivility on end-of-work negative affect and explored potential individual and organizational moderators. Data collected from 76 full-time employees across 10 consecutive working days revealed that daily workplace incivility positively predicted end-of-work negative affect while controlling for before-work negative affect. Further, the relationship was stronger for people with low emotional stability, high hostile attribution bias, external locus of control, and people experiencing low chronic workload and more chronic organizational constraints, as compared with people with high emotional stability, low hostile attribution bias, internal locus of control, and people experiencing high chronic workload and fewer chronic organizational constraints, respectively.

    This study was done to develop a cell phone addiction scale for Korean adolescents. The process included construction of a conceptual framework, generation of initial items, verification of content validity, selection of secondary items, preliminary study, and extraction of final items. The participants were 577 adolescents in two middle schools and three high schools. Item analysis, factor analysis, criterion related validity, and internal consistency were used to analyze the data. Twenty items were selected for the final scale, and categorized into 3 factors explaining 55.45% of total variance. The factors were labeled as withdrawal/tolerance (7 items), life dysfunction (6 items), and compulsion/persistence (7 items). The scores for the scale were significantly correlated with self-control, impulsiveness, and cell phone use. Cronbach's alpha coefficient for the 20 items was .92. Scale scores identified students as cell phone addicted, heavy users, or average users. The above findings indicate that the cell phone addiction scale has good validity and reliability when used with Korean adolescents.

    Full Text Available Youth have access to and utilize various types of technology at a growing rate. Cell phones are a portable way for adolescents to remain in constant contact with friends, parents, and others. While White youth are more likely to have a cell phone compared to Latino youth, the trends for cell phone use are similar among all teens with text messaging serving as the most popular means of communication. Despite their high volume of communication with others via cell phones, adolescents are likely to have little or no adult supervision while using technology. With a lack of parental supervision or awareness regarding youth technology use, adolescents may be especially vulnerable to cyberbullying and other negative health impacts. The current study investigates cell phone and texting use among a community sample of Latino adolescents and examines how parental rules regarding cell phone use influences adolescents’ cell phone and texting behaviors.

    The purpose of this research is to measure cell phone use among high school adolescents and the factors associated with intensive cell phone use (depressive symptoms, social isolation, drug and alcohol use, school failure, and cell phone dependence). We conducted a cross-sectional survey study of 1,328 adolescents aged 13 to 20 years in nine secondary schools of the Community of Madrid between January to April 2007. The mean age of sample participants was 15.7 years. Almost all (96.5%) had their own cell phone (80.5% had one, and 15.9% had two or more). Some 54.8% take it to school and 46.1% keep it on during class; 41.7% use it intensively. The estimated prevalence of cell phone dependence was 20% (26.1% in females, 13% in males). Intensive cell phone use was associated with female sex, rural school location, good family economy, smoking tobacco, excessive alcohol consumption, depression, cell phone dependence, and school failure. More health education is needed to promote correct and effective cell phone use among adolescents. Factors associated with intensive use and dependence should be considered for possible intervention activities.

    To evaluate the potential carcinogenic effects of radiofrequency energy (RFE) emitted by cell phones on human thyroid primary cells. Primary thyroid cell culture was prepared from normal thyroid tissue obtained from patients who underwent surgery at our department. Subconfluent thyroid cells were irradiated under different conditions inside a cell incubator using a device that simulates cell phone-RFE. Proliferation of control and irradiated cells was assessed by the immunohistochemical staining of antigen Kiel clone-67 (Ki-67) and tumor suppressor p53 (p53) expression. DNA ploidy and the stress biomarkers heat shock protein 70 (HSP70) and reactive oxygen species (ROS) was evaluated by fluorescence-activated cell sorting (FACS). Our cells highly expressed thyroglobulin (Tg) and sodium-iodide symporter (NIS) confirming the origin of the tissue. None of the irradiation conditions evaluated here had an effect neither on the proliferation marker Ki-67 nor on p53 expression. DNA ploidy was also not affected by RFE, as well as the expression of the biomarkers HSP70 and ROS. Our conditions of RFE exposure seem to have no potential carcinogenic effect on human thyroid cells. Moreover, common biomarkers usually associated to environmental stress also remained unchanged. We failed to find an association between cell phone-RFE and thyroid cancer. Additional studies are recommended.

Indigenously prepared cell-phone usage related questionnaire was used in the present study after approval by the Institutional Ethics/Scientific Committees. The questionnaire had 41 items and was made to assess the cell-phone usage parameters, utility in clinical practice, awareness, and to compare parameters between oncology specialties. Between November 2009 and January 2010, the questionnaire was sent as an E-mail attachment to 200 oncologists in India. In all, 123 responses were received (61% responders); 84 (68.3%) were RO. The median age of responders was 35 years. Overall, 80% felt handicapped without cell-phone. The Mean cell-phone score, an index to assess overall usefulness over a score of 1-10, was 6.46 (median 7, standard deviation 1.709). There was no significant difference between RO, MO and SO in duration of usage (P = 0.235), number of cell-phones (P = 0.496), call duration per day (P = 0.490) and dependence on cell-phone (P = 0.574). Age of starting cell-phone usage was earlier in RO (P = 0.086).

    Objective: Smart phones have rapidly become an integral, and for some, an essential communication device worldwide. The issue of identity has always been a subject of interest among psychologists. The present study was conducted to compare personal and national identity and their subscales between cell phone addicts and non-addicts. Method : In this cross-sectional study, 500 student cell phone users from various universities in Tehran were recruited using stratified sampling. Participants completed cell phone addiction questionnaires including Mobile Phone Problematic Use Scale (MPPUS), Cell Phone Dependency Questionnaire (CPDQ), Personal Identity Development Questionnaire, Extended Objective Measure of Ego Identity Status (EOMEIS) and National Identity Questionnaire. Then, the subscales of these instruments were analyzed using SPSS Version 20. Results: Results of this study revealed significant differences between cell phone addicts and non-addicts in the scores of national identity, personal identity, and most subscales, except for some subscales (Pphone addiction (r=-0.35, -0.33, respectively).On the other hand, after controlling for the confounder variables, we found that national identity had an effect on cell phone addiction(OR=0.05, CI=0.92-0.98). Conclusion: The results of this study indicated that cell phone overuse may be correlated with defects in some aspects of national and personal identity.

    Introduction Few studies have examined the psychological factors underlying the association between cell phone use and motor vehicle crash. We sought to examine the factor structure and convergent validity of a measure of problematic cell phone use and explore whether compulsive cell phone use is associated with a history of motor vehicle crash. Methods We recruited a sample of 383 undergraduate college students to complete an on-line assessment that included cell phone use and driving history. We explored the dimensionality of the Cell Phone Overuse Scale (CPOS) using factor analytic methods. Ordinary least squares regression models were used to examine associations between identified subscales and measures of impulsivity, alcohol use, and anxious relationship style to establish convergent validity. We used negative binomial regression models to investigate associations between the CPOS and motor vehicle crash incidence. Results We found the CPOS to be comprised of four subscales: anticipation, activity interfering, emotional reaction, and problem recognition. Each displayed significant associations with aspects of impulsivity, problematic alcohol use, and anxious relationship style characteristics. Only the anticipation subscale demonstrated statistically significant associations with reported motor vehicle crash incidence, controlling for clinical and demographic characteristics (RR 1.13, CI 1.01 to 1.26). For each one-point increase on the 6-point anticipation subscale, risk for previous motor vehicle crash increased by 13%. Conclusions Crash risk is strongly associated with heightened anticipation about incoming phone calls or messages. The mean score on the CPOS is associated with increased risk of motor vehicle crash but does not reach statistical significance. PMID:23910571

    To meet challenges arising from increasing rates of noncoverage in US landline-based telephone samples due to cell-phone-only households, the Behavioral Risk Factor Surveillance System (BRFSS) expanded a traditional landline-based random digit dialing survey to a dual-frame survey of landline and cell phone numbers. In 2008, a survey of adults with cell phones only was conducted in parallel with an ongoing landline-based health survey in 18 states. The authors used the optimal approach to allocate samples into landline and cell-phone-only strata and used a new approach to weighting state-level landline and cell phone samples. They developed logistic models for each of 16 health indicators to examine whether exclusion of adults with cell phones only affected estimates after adjustment for demographic characteristics. The extents of the potential biases in landline telephone surveys that exclude cell phones were estimated. Biases resulting from exclusion of adults with cell phones only from the landline-based survey were found for 9 out of the 16 health indicators. Because landline noncoverage rates for adults with cell phones only continue to increase, these biases are likely to increase. Use of a dual-frame survey of landline and cell phone numbers assisted the BRFSS efforts in obtaining valid, reliable, and representative data.

    Full Text Available Abstract This article presents a study on appropriation and educational uses of cell phones. For the research, a random sample of 954 students and 246 teachers was selected, representing respectively 12% and 24% of the total population in two facilities of UABC in Ensenada, Mexico. Our survey showed that 97% of teachers or students have some kind of cell phone or smartphone. However, we observed that one of every four interactions with the mobile device had a concrete educational purpose. We also found that in general the educational use of the cell phone is mainly aimed to establish communication between the students and to access information via Internet. However, in spite of its limitations, our results show that the cell phone is a technological tool with great pedagogical potential. We suggest that institutional policies are necessary in order to tap that the cell phone potential to adequately support the teaching-learning process.

    The rapid proliferation of cell phone use and the accompanying decline in landline service in recent years have resulted in substantial potential for coverage bias in landline random-digit-dial telephone surveys, which has led to the implementation of dual-frame designs that incorporate both landline and cell phone samples. Consequently,…

    We all have to act in a more respectful and careful manner towards each other, and this also applies on the road. We therefore have to pay particular attention to the most vulnerable people (cyclists, pedestrians, etc.).   A couple of articles were published on the issue to raise awareness among drivers on the importance of road safety rules (see the CERN Bulletin on 10 September and 22 October 2012). Incivilities such as vehicles parked in a hazardous way, right of way violations, etc. can cause serious accidents with physical and/or material consequences. In compliance with the 2013 road safety goal, presented earlier this year by CERN’s Director-General, incivilities reported in the A2 Form will, from now on, be systemically followed up, as stated in the procedure set up by the HSE Unit in collaboration with the GS Department. The follow-up process puts special emphasis on prevention, as it is mainly a reminder of CERN traffic regulations...

  13. Media Discourse on Cell Phone Technology and “Left-Behind Children” in China

    2016-06-01

    Full Text Available Through critical analysis of selected news stories from sina.com from 2010 to 2015 about cell phones and “left-behind children” in China, this article examines media discourses on the relationship between migrant families and communication technology. The author finds that the roles of cell phones in their lives are portrayed in the following narratives: 1 cell phones are highly valuable for connecting family members living apart; 2 cell phones are used as a problem-solver in charity giving and rural development projects; 3 cell phones can bring unexpected risks to children lacking media literacy; and 4 cell phones could harbour or unleash evil—associated with increasing cases of juvenile delinquency or crime stories. The author discusses how the different institutional goals of social agencies, corporations, educators, and law enforcement contribute to the polarity of the discourses, reflecting the societal anxieties over unsupervised use of mobile devices by adolescents, as well as the cultural and political implications of empowering the “have-nots” of the digital divide by improving access to communication technology.

  14. Preliminary research developing a theory of cell phone distraction and social relationships.

    2016-01-01

    Motor vehicle crashes remain the leading cause of death and injury for people aged 5-34, accounting annually for over 3000 deaths, and 100 times as many injuries. It is well established that distracted driving, and cell phone use while driving in particular, pose significant crash risk to drivers. Research has demonstrated that drivers are well aware of this danger but over 90% of drivers report using a cell phone while driving. Given the likely role that social influence plays in how people use cell phones while driving surprisingly little research has been conducted investigating to whom drivers are talking or texting. We report the results of a national survey to determine who drivers are most likely to call or text when behind the wheel and compared these results with general cell phone calling and texting patterns as well as previous findings on the prevalence of calling and texting while driving. The results suggest that social distance is a key factor in cell phone use while driving: Teens are more likely to talk with parents, and adults are more likely to talk with spouses than general calling patterns would suggest. We discuss whether the purpose of calls made while driving, such as coordination, could help explain these patterns. We propose next steps for further examining the role social relationships play in cell phone use while driving to potentially reduce teen driver cell phone use by lowering the number of calls from parents.

    Full Text Available This article describes “humanistic antidotes” to offset the widespread social media/cell phone addiction prevalent in current US college classrooms. The inappropriate use of cell phones to engage in social media in college classrooms is a pervasive problem that many college instructors have complained about.  The dominant focus of this article is in humanistic education, in which the author's efforts at getting psychology college students to put away their cell phones, “talk with each other,” and gain awareness of the detrimental effects of social media addiction and narcissism is illustrated.  The methodology utilized in this article is based upon autoethnographic research, where relevant experiences of the researcher are considered to be an informative and fundamental part of the research. The author describes in narrative form his relevant experiences in formulating humanistic antidotes to the excessive and inappropriate use of cell phones to engage in social media, that he encountered in his college psychology teaching. These humanistic antidotes are described as a three-step process: 1 take necessary actions to eliminate as much as possible the inappropriate use of cell phones in the classroom; 2 engage students in required personal/academic small group discussions every class period; 3 include small discussions about the excessive and inappropriate use of cell phones and social media, and require them to write and present project papers of their own choosing, which will likely include some papers on the topic of cell phone/social media addiction, demonstrating their awareness of the detrimental aspects of this pervasive problem.

    The association between cell phone use and the development of parotid tumors is controversial. Because there is unequivocal evidence that the microenvironment is important for tumor formation, we investigated in the parotid glands whether cell phone use alters the expression of gene products related to cellular stress. We used the saliva produced by the parotid glands of 62 individuals to assess molecular alterations compatible with cellular stress, comparing the saliva from the gland exposed to cell phone radiation (ipsilateral) to the saliva from the opposite, unexposed parotid gland (contralateral) of each individual. We compared salivary flow, total protein concentration, p53, p21, reactive oxygen species (ROS), and salivary levels of glutathione (GSH), heat shock proteins 27 and 70, and IgA between the ipsilateral and contralateral parotids. No difference was found for any of these parameters, even when grouping individuals by period of cell phone use in years or by monthly average calls in minutes. We provide molecular evidence that the exposure of parotid glands to cell phone use does not alter parotid salivary flow, protein concentration, or levels of proteins of genes that are directly or indirectly affected by heat-induced cellular stress. ©2014 American Association for Cancer Research.

    Full Text Available Nowadays development of cell phone network provides huge and ubiquitous data, with wide application in transportation science. One of the most important advantages of these kinds of data is enabling the process of collecting information without any active users’ interference. A big data set consisting of 300,000 cell phone users’ information in Shiraz are studied. This data set includes spatiotemporal information of travelers for every 5 minutes in a time span of 40 hours in two consecutive days. The spatial part of each user’s information contains the position of the BTS (Base Transceiver Station to which his cell phone is currently connected. Due to the existence of outliers, it is necessary to smooth the data initially. One of the main reasons of errors in the data set is ping pong handover, which leads to false transitions and must be eliminated. After the data preparation, stay locations are determined for each user and a trajectory for each pair of origin and destination is estimated. At this step based on network information of the city, a method to match trajectories with the network map is applied. Finally the obtained results indicate whether travelers choose the shortest path or other possible alternatives.

    Likening mobile phone use dependency to the classification of excessive behaviors may be necessarily equivalent in seriousness to previously established addictions such as problematic computing or excessive gambling. The aim of the study explores into the behavior of excessive use of mobile phones as a pathological behavior. Two studies investigated criteria for problematic mobile phone usage by examining student (Study 1, N = 301) and nonstudent (Study 2, N = 362) responses to a set of adapted mobile phone addiction inventories. Study 1 investigated cell phone addiction inventories as constructs designed to measure problematic cell phone use. Additionally, Study 2 sought to predict age, depression, extraversion, emotional stability, impulse control, and self-esteem as independent variables that augment respondents' perceptions of problematic use. The results from Study 1 and Study 2 indicate that 10 to 25% of the participants tested exhibited problematic cell phone usage. Additionally, age, depression, extraversion, and low impulse control are the most suitable predictors for problematic use. The results of the two studies indicate that problematic mobile phone use does occur and ought to be taken seriously by the psychological community. Presently, there is limited data providing conclusive evidence for a comprehensible categorization of cell phone addiction, as well as a unified explanatory model specific to problematic mobile phone use. Studies such as this one may contribute substantial findings, adding scientific significance, and offering a valuable submission for the ongoing progress of creating intervention frameworks relative to "virtual addictions".

    There is tremendous concern regarding the possible adverse effects of cell phone microwaves. Contradictory results, however, have been reported for the effects of these waves on the body. In the present study, the effect of cell phone microwaves on sperm parameters and total antioxidant capacity was investigated with regard to the duration of exposure and the frequency of these waves. This experimental study was performed on 28 adult male Wistar rats (200-250 g). The animals were randomly assigned to four groups (n=7): i. control; ii. two-week exposure to cell phone-simulated waves; iii. three-week exposure to cell phonesimulated waves; and iv. two-week exposure to cell phone antenna waves. In all groups, sperm analysis was performed based on standard methods and we determined the mean sperm total antioxidant capacity according to the ferric reducing ability of plasma (FRAP) method. Data were analyzed by one-way ANOVA followed by Tukey's test using SPSS version 16 software. The results indicated that sperm viability, motility, and total antioxidant capacity in all exposure groups decreased significantly compared to the control group (pcell phone waves can decrease sperm viability and motility in rats. These waves can also decrease sperm total antioxidant capacity in rats and result in oxidative stress.

    A majority of states now restrict teenagers from using a mobile communication device while driving. The effect of these restrictions is largely unknown. In a previous study, we found North Carolina's teenage driver cell phone restriction had little influence on young driver behavior four months after the law took effect (Foss et al., 2009). The goal of the present study was to examine the longer-term effect of North Carolina's cell phone restriction. It was expected that compliance with the restriction would increase, as awareness of the restriction grew over time. Teenagers were observed at high schools in North Carolina approximately two years after the law was implemented. Observations were also conducted in South Carolina, which did not have a cell phone restriction. In both states, there was a broad decrease in cell phone use. A logistic regression analysis showed the decrease in cell phone use did not significantly differ between the two states. Although hand-held cell phone use decreased, there was an increase in the likelihood that drivers in North Carolina were observed physically manipulating a phone. Finally, a mail survey of teenagers in North Carolina showed awareness for the cell phone restriction now stands at 78% among licensed teens. Overall, the findings suggest North Carolina's cell phone restriction has had no long-term effect on the behavior of teenage drivers. Moreover, it appears many teenage drivers may be shifting from talking on a phone to texting. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Context The dramatic increase in use of cellular telephones has generated concern about possible negative effects of radiofrequency signals delivered to the brain. However, whether acute cell phone exposure affects the human brain is unclear. Objective To evaluate if acute cell phone exposure affects brain glucose metabolism, a marker of brain activity. Design, Setting, and Participants Randomized crossover study conducted between January 1 and December 31, 2009, at a single US laboratory among 47 healthy participants recruited from the community. Cell phones were placed on the left and right ears and positron emission tomography with (18F)fluorodeoxyglucose injection was used to measure brain glucose metabolism twice, once with the right cell phone activated (sound muted) for 50 minutes (“on” condition) and once with both cell phones deactivated (“off” condition). Statistical parametric mapping was used to compare metabolism between on and off conditions using paired t tests, and Pearson linear correlations were used to verify the association of metabolism and estimated amplitude of radiofrequency-modulated electromagnetic waves emitted by the cell phone. Clusters with at least 1000 voxels (volume >8 cm3) and P < .05 (corrected for multiple comparisons) were considered significant. Main Outcome Measure Brain glucose metabolism computed as absolute metabolism (µmol/100 g per minute) and as normalized metabolism (region/whole brain). Results Whole-brain metabolism did not differ between on and off conditions. In contrast, metabolism in the region closest to the antenna (orbitofrontal cortex and temporal pole) was significantly higher for on than off conditions (35.7 vs 33.3 µmol/100 g per minute; mean difference, 2.4 [95% confidence interval, 0.67–4.2]; P = .004). The increases were significantly correlated with the estimated electromagnetic field amplitudes both for absolute metabolism (R = 0.95, P < .001) and normalized metabolism (R = 0.89; P < .001

    This study examined the influence of authentic leadership, person-job fit with 6 areas of worklife, and civility norms on coworker incivility and burnout among new graduate nurses. New graduate nurses report experiencing high levels of workplace incivility from coworkers, which has been found to negatively impact their job and career satisfaction and increase their intention to leave. The role of civility norms in preventing burnout and subsequent exposure to incivility from coworkers has yet to be examined among new graduate nurses. A cross-sectional mail survey of 993 new graduate nurses across Canada was conducted. The results supported the hypothesized relationships between study variables. Civility norms play a key role in preventing early career burnout and coworker incivility experienced by new graduate nurses. Leaders can influence civility norms by engaging in authentic leadership behaviors and optimizing person-job fit.

    There has been increasing interest in the impact of information and communication technologies, such as the computer and Internet, on physical and mental health status, but relatively little is known about the health effects of using cell phones. This study investigates how cell phone usage is associated with levels of depressive symptoms among Japanese men and women aged 65 years and older. We focus on social relationships, particularly intergenerational relationships between older parents and adult children, as a possible mediator in the association of cell phone use with late-life depressive symptoms. We therefore hypothesize that using cell phones contributes to the psychological well-being of older adults primarily through encouraging social relationships. We used 4 waves of data from the Nihon University Japanese Longitudinal Study of Aging (2001-2009) to analyze the impact of cell phone use on depressive symptoms. RESULTS are based on ordinary least squares regression analyses. Although the use of cell phones was related to lower levels of depressive symptoms among elderly Japanese people, controlling for sociodemographic characteristics and physical health conditions wiped out the effects for men. In contrast, the protective effects of using cell phones persisted among women, even net of all controls. Moreover, the impact of using cell phones was not explained by filial relationship measures, suggesting that cell phone use influences the mental health of older women independently of social engagement. Among the many advantages brought about by recent technological developments, cell phones appear to be an important contributor to the psychological well-being of Japanese elders. Researchers and policy makers should prioritize access to new technologies for older adults. © 2014 S. Karger AG, Basel.

    Previous studies have reported associations between prenatal cell phone use and child behavioral problems, but findings have been inconsistent and based on retrospective assessment of cell phone use. This study aimed to assess this association in a multi-national analysis, using data from three cohorts with prospective data on prenatal cell phone use, together with previously published data from two cohorts with retrospectively collected cell phone use data. We used individual participant data from 83,884 mother-child pairs in the five cohorts from Denmark (1996-2002), Korea (2006-2011), the Netherlands (2003-2004), Norway (2004-2008), and Spain (2003-2008). We categorized cell phone use into none, low, medium, and high, based on frequency of calls during pregnancy reported by the mothers. Child behavioral problems (reported by mothers using the Strengths and Difficulties Questionnaire or Child Behavior Checklist) were classified in the borderline/clinical and clinical ranges using validated cut-offs in children aged 5-7years. Cohort specific risk estimates were meta-analyzed. Overall, 38.8% of mothers, mostly from the Danish cohort, reported no cell phone use during pregnancy and these mothers were less likely to have a child with overall behavioral, hyperactivity/inattention or emotional problems. Evidence for a trend of increasing risk of child behavioral problems through the maternal cell phone use categories was observed for hyperactivity/inattention problems (OR for problems in the clinical range: 1.11, 95%CI 1.01, 1.22; 1.28, 95%CI 1.12, 1.48, among children of medium and high users, respectively). This association was fairly consistent across cohorts and between cohorts with retrospectively and prospectively collected cell phone use data. Maternal cell phone use during pregnancy may be associated with an increased risk for behavioral problems, particularly hyperactivity/inattention problems, in the offspring. The interpretation of these results is unclear

    An iPhone-based digital image colorimeter (DIC) was fabricated as a portable tool for monitoring tetracycline (TC) in bovine milk. An application named ColorConc was developed for the iPhone that utilizes an image matching algorithm to determine the TC concentration in a solution. The color values; red (R), green (G), blue (B), hue (H), saturation (S), brightness (V), and gray (Gr) were measured from each pictures of the TC standard solutions. TC solution extracted from milk samples using solid phase extraction (SPE) was captured and the concentration was predicted by comparing color values with those collected in a database. The amount of TC could be determined in the concentration range of 0.5-10 μg mL(-1). The proposed DIC-iPhone is able to provide a limit of detection (LOD) of 0.5 μg mL(-1) and limit of quantitation (LOQ) of 1.5 μg mL(-1). The enrichment factor was 70 and color of the extracted milk sample was a strong yellow solution after SPE. Therefore, the SPE-DIC-iPhone could be used for the assay of TC residues in milk at the concentration lower than LOD and LOQ of the proposed technique. Copyright © 2015 Elsevier Ltd.

    Background and aims: Likening mobile phone use dependency to the classification of excessive behaviors may be necessarily equivalent in seriousness to previously established addictions such as problematic computing or excessive gambling. The aim of the study explores into the behavior of excessive use of mobile phones as a pathological behavior. Methods: Two studies investigated criteria for problematic mobile phone usage by examining student (Study 1, N = 301) and nonstudent (Study 2, N = 362) responses to a set of adapted mobile phone addiction inventories. Study 1 investigated cell phone addiction inventories as constructs designed to measure problematic cell phone use. Additionally, Study 2 sought to predict age, depression, extraversion, emotional stability, impulse control, and self-esteem as independent variables that augment respondents’ perceptions of problematic use. Results: The results from Study 1 and Study 2 indicate that 10 to 25% of the participants tested exhibited problematic cell phone usage. Additionally, age, depression, extraversion, and low impulse control are the most suitable predictors for problematic use. Conclusions: The results of the two studies indicate that problematic mobile phone use does occur and ought to be taken seriously by the psychological community. Presently, there is limited data providing conclusive evidence for a comprehensible categorization of cell phone addiction, as well as a unified explanatory model specific to problematic mobile phone use. Studies such as this one may contribute substantial findings, adding scientific significance, and offering a valuable submission for the ongoing progress of creating intervention frameworks relative to “virtual addictions”.

    Male infertility constitutes 30-40% of all infertility cases. Some studies have shown a continuous decline in semen quality since the beginning of the 20th century. One postulated contributing factor is radio frequency electromagnetic radiation emitted from cell phones. This study investigates an association between characteristics of cell phone usage and semen quality. Questionnaires accessing demographic data and characteristics of cell phone usage were completed by 106 men referred for semen analysis. Results were analysed according to WHO 2010 criteria. Talking for ≥1 h/day and during device charging were associated with higher rates of abnormal semen concentration (60.9% versus 35.7%, P cell phone usage may bear adverse effects on sperm concentration. Investigation using large-scale studies is thus needed. Copyright © 2015 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

    We demonstrate wide-field fluorescent and darkfield imaging on a cell-phone with compact, light-weight and cost-effective optical components that are mechanically attached to the existing camera unit of the cell-phone. For this purpose, we used battery powered light-emitting diodes (LEDs) to pump the sample of interest from the side using butt-coupling, where the pump light was guided within the sample cuvette to uniformly excite the specimen. The fluorescent emission from the sample was then imaged using an additional lens that was positioned right in front of the existing lens of the cell-phone camera. Because the excitation occurs through guided waves that propagate perpendicular to our detection path, an inexpensive plastic colour filter was sufficient to create the dark-field background required for fluorescent imaging, without the need for a thin-film interference filter. We validate the performance of this platform by imaging various fluorescent micro-objects in 2 colours (i.e., red and green) over a large field-of-view (FOV) of ∼81 mm(2) with a raw spatial resolution of ∼20 μm. With additional digital processing of the captured cell-phone images, through the use of compressive sampling theory, we demonstrate ∼2 fold improvement in our resolving power, achieving ∼10 μm resolution without a trade-off in our FOV. Further, we also demonstrate darkfield imaging of non-fluorescent specimen using the same interface, where this time the scattered light from the objects is detected without the use of any filters. The capability of imaging a wide FOV would be exceedingly important to probe large sample volumes (e.g., >0.1 mL) of e.g., blood, urine, sputum or water, and for this end we also demonstrate fluorescent imaging of labeled white-blood cells from whole blood samples, as well as water-borne pathogenic protozoan parasites such as Giardia Lamblia cysts.

    The purpose of this investigation was to identify risky driving behaviors and dispositions that distinguish drivers who use a cell phone while operating a motor vehicle from non-cell phone using drivers. Annual telephone surveys were used to identify drivers who reported using a cell phone while driving in the last month (n=1803) and were compared to those who said they did not use cell phones while driving (n=1578). Cell phone using drivers were more likely to report driving while drowsy, going 20 mph over the speed limit, driving aggressively, running a stop sign or red light, and driving after having had several drinks. They were also more likely to have had a prior history of citation and crash involvement than non-cell phone using drivers. Cell phone using drivers also reported they were less careful and more in a hurry when they drive than non-cell phone using drivers. Cell phone using drivers report engaging in many behaviors that place them at risk for a traffic crash, independent of the specific driving impairments that cell phone usage may produce. Strategies that combine coordinated and sustained enforcement activities along with widespread public awareness campaigns hold promise as effective countermeasures for these drivers, who resemble aggressive drivers in many respects.

    Incivility has negative consequences in the workplace and remains a prevalent issue in nursing. Research has consistently linked incivility to nurse burnout and, in turn, to poor mental health and turnover intentions. To retain high-quality nurses, it is important to understand what factors might protect nurses from the negative effects of workplace mistreatment. The aim of the study was to investigate the role of relational occupational coping self-efficacy in protecting nurses from workplace incivility and related burnout and turnover intentions. A two-wave national sample of 596 Canadian nurses completed mail surveys both at Time 1 and one year later at Time 2. Structural equation modeling was used to test the hypothesized model. The model showed a good fit, and most of the hypothesized paths were significant. Overall, the results supported the hypothesized protective effect of relational occupational coping self-efficacy against incivility and later burnout, mental health, and turnover intentions. Relational occupational coping self-efficacy is an important protective factor against negative work behavior. Organizations should provide nurses with opportunities to build their coping strategies for managing job demands and difficult interpersonal interactions. Similarly, providing exposure to effective role models and providing meaningful verbal encouragement are other sources of efficacy information for building nurses' relational coping self-efficacy.

    Using cell phones while driving contribute to distractions which can potentially cause minor or major road traffic injuries and also stress among other drivers. With this background, the study was done to ascertain the proportion of handheld cell phone use while driving among road users in Mysore city and also patterns of the use by the day of week, type of road, and type of vehicle. The study was conducted in Mysore, Karnataka, India. Four stretches of roads were observed thrice daily for 1 week. The total number of vehicles passing through the stretch and the number and characteristics of drivers using hand-held cell was noted. Pearson's Chi-square test was used to ascertain the significance of the difference in proportions. The overall proportion of cell phone users was calculated as 1.41/100 vehicles. The observed use of handheld cell phones was 1.78 times higher on nonbusy roads than busy roads ( Χ 2 = 25.79, P phone users were driving a two wheeler, the proportion being 50.5% in busy roads, and 67% in nonbusy roads. There was no difference in the proportion of cell phone use by time of the day or across different days of the week. The proportion of drivers who use cell phones is found to be relatively lower, and use of cell phones was higher on nonbusy roads.

    Science.gov (United States)

    Kruger, Daniel J; Djerf, Jaikob M

    2016-01-01

    Mobile cell phone users have reported experiencing ringing and/or vibrations associated with incoming calls and messages, only to find that no call or message had actually registered. We believe this phenomenon can be understood as a human signal detection issue, with potentially important influences from psychological attributes. We hypothesized that individuals higher in attachment anxiety would report more frequent phantom cell phone experiences, whereas individuals higher in attachment avoidance would report less frequent experiences. If these experiences are primarily psychologically related to attributes of interpersonal relationships, associations with attachment style should be stronger than for general sensation seeking. We also predicted that certain contexts would interact with attachment style to increase or decrease the likelihood of experiencing phantom cell phone calls and messages. Attachment anxiety directly predicted the frequency of phantom ringing and notification experiences, whereas attachment avoidance and sensation seeking did not directly predict frequency. Attachment anxiety and attachment avoidance interacted with contextual factors (expectations for a call or message and concerned about an issue that one may be contacted about) in the expected directions for predicting phantom cell phone experiences.

    Electromagnetic fields (EMF) are classified as "possibly carcinogenic" by the International Agency for Research on Cancer (IARC). Some publications have reported associations between EMF exposure and DNA damage, but many other studies contradict such findings. Cytomorphological changes, such as micronuclei (MN), indicative of genomic damage, are biomarkers of genotoxicity. To test whether mobile phone-associated EMF exposure affects the MN frequency in exfoliated buccal cells, we obtained cells smears from the left and right inner cheeks of healthy mobile phone users, aged 18-30 (n=86), who also completed a characterization survey. MN frequencies were tested for potential confounding factors and for duration of phone use and preferential side of mobile phone use. No relationship was observed between MN frequency and duration of mobile phone use in daily calls. Cells ipsilateral to mobile phone use did not present a statistically significantly higher MN frequency, compared to cells contralateral to exposure. A highly statistically significant (pphone-associated EMF do not to induce MN formation in buccal cells at the observed exposure levels. Copyright © 2017 Elsevier B.V. All rights reserved.

    2013-12-01

    The apparently higher crash risk among individuals who use cell phones while driving may be due both to the direct interference of cell phone use with the driving task and tendencies to engage in risky driving behaviors independent of cell phone use. Measurements of actual highway driving performance, self-reported aberrant driving behaviors as measured by the Manchester Driver Behavior Questionnaire (DBQ), and attitudes toward speeding, passing behaviors and relative concern about being involved in a crash were assessed. Individuals who reported frequently using cell phones while driving were found to drive faster, change lanes more frequently, spend more time in the left lane, and engage in more instances of hard braking and high acceleration events. They also scored higher in self-reported driving violations on the DBQ and reported more positive attitudes toward speeding and passing than drivers who did not report using a cell phone regularly while driving. These results indicate that a greater reported frequency of cell phone use while driving is associated with a broader pattern of behaviors that are likely to increase the overall risk of crash involvement.

    Full Text Available Cell phones have become a vital part of everyday life. However, the health risks associated with their usage are often overlooked. Recently, evidence from several studies supports a growing claim that cell phone usage may have a detrimental effect on sperm parameters leading to decreased male fertility. Nonetheless, other studies showed no conclusive link between male infertility and cell phone usage. The ambiguity of such results is attributed to the lack of a centralized assay for measuring inflicted damage caused by cell phones. Study design, ethics, and reproducibility are all aspects which must be standardized before any conclusions can be made.

    2010-12-01

    This study examined how cell-phone use is related to interpersonal motives for using cell phones, face-to-face communication, and loneliness. A survey of 232 college students who owned a cell phone revealed that affection and inclusion were relatively strong motivations for using voice calls and text messaging, and that interpersonal motives were positively related to the amount of cell-phone use, including calling and texting. The amount of face-to-face interaction was positively associated with the participants' cell-phone use and their interpersonal motives for using cell phones: the more the participants engaged in face-to-face interaction with other people, the higher their motives were and the more frequent cell-phone use was. Loneliness did not have a direct relation to cell-phone use. Instead, the participants with higher levels of loneliness were less likely to engage in face-to-face social interaction, which led them to use cell phones less and to be less motivated to use cell phones for interpersonal purposes.

    Full Text Available Mobile phone usage currently exceeds landline communication in Africa. The extent of this usage has raised concerns about the long-term health effects of the ongoing use of mobile phones. To assess the physiological effects of radiation from mobile phones in vitro, MCF-7 breast adenocarcinoma cells were exposed to 2W/kg non-thermal 900-MHz mobile phone radiation. The effects investigated were those on metabolic activity, cell morphology, cell cycle progression, phosphatidylserine (PS externalisation and the generation of reactive oxygen species and nitrogen species. Statistically insignificant increases in mitochondrial dehydrogenase activity were observed in irradiated cells when compared to controls. Fluorescent detection of F-actin demonstrated an increase in F-actin stress fibre formation in irradiated MCF-7 cells. Cell cycle progression revealed no statistically significant variation. A small increase in early and late apoptotic events in irradiated MCF-7 cells was observed. No statistically significant changes were observed in reactive oxygen and reactive nitrogen species generation. In addition, quantitative and qualitative analyses of cell cycle activity and nuclear and cytosolic changes, respectively, revealed no significant changes. In conclusion, exposure to 1 h of 900-MHz irradiation induced an increase in PS externalisation and an increase in the formation of F-actin stress fibres in MCF-7 cells. Data obtained from this study, and their correlation with other studies, provides intriguing links between radio frequency radiation and cellular events and warrant further investigation.

    Although research on workplace aggression has long recognized job stressors as antecedents, little is known about the process through which employee responses to stressful workplace demands escalate from relatively mild interactions into more intense behaviors. This study investigates the influence that employees' perceptions of role stress (ambiguity, conflict, overload) have on their aggressive behavior by affecting their perceptions of incivility, and whether these downstream effects depend on personality traits (neuroticism, agreeableness, conscientiousness). Results supported moderated mediation, such that the indirect effects of perceived role ambiguity and role conflict on enacted aggression through experienced incivility varied according to individual differences in personality.

In this descriptive correlational study, a sample including 100 students of Payame Noor University (PNU), Reyneh Center, Iran, in the academic year of 2013-2014 was selected using volunteer sampling. Participants were asked to complete the adult attachment inventory (AAI), Beck depression inventory-13 (BDI-13) and the cell phone overuse scale (COS). Results of the stepwise multiple regression analysis showed that depression and avoidant attachment style were the best predictors of students' cell phone addiction (R(2) = 0.23). The results of this study highlighted the predictive value of depression and avoidant attachment style concerning students' cell phone addiction.

    Background The objective of this study was to evaluate the evidence on the impact of cell phone interventions for persons with diabetes and/or obesity in improving health outcomes and/or processes of care for persons with diabetes and/or obesity. Methods We searched Medline (1966–2007) and reviewed reference lists from included studies and relevant reviews to identify additional studies. We extracted descriptions of the study design, sample size, patient age, duration of study, technology, educational content and delivery environment, intervention and control groups, process and outcome measures, and statistical significance. Results In this review, we included 20 articles, representing 18 studies, evaluating the use of a cell phone for health information for persons with diabetes or obesity. Thirteen of 18 studies measured health outcomes and the remaining 5 studies evaluated processes of care. Outcomes were grouped into learning, behavior change, clinical improvement, and improved health status. Nine out of 10 studies that measured hemoglobin A1c reported significant improvement among those receiving education and care support. Cell phone and text message interventions increased patient–provider and parent–child communication and satisfaction with care. Conclusions Providing care and support with cell phones and text message interventions can improve clinically relevant diabetes-related health outcomes by increasing knowledge and self-efficacy to carry out self-management behaviors.

    There is controversy on the effects of the non-ionizing radiation emitted by cell phones on cellular processes and the impact of such radiation exposure on health. The purpose of this study was to investigate whether cell phone use alters cytokine expression in the saliva produced by the parotid glands. Cytokine expression profile was determined by enzyme linked immuno sorbent assay (ELISA) in the saliva produced by the parotid glands in healthy volunteers, and correlated with self-reported cell phone use and laterality. The following parameters were determined, in 83 Brazilian individuals in saliva produced by the parotid glands comparing the saliva from the gland exposed to cell phone radiation (ipsilateral) to that from the contralateral parotid: salivary flow, total protein concentration, interleukin 1 β (IL-1 β), interleukin 6 (IL-6), interleukin 10 (IL-10), interferon γ (IFN-γ), and tumor necrosis factor α (TNF-α) salivary levels by ELISA. After multiple testing correction, decreased IL-10 and increased IL-1β salivary levels in the ipsilateral side compared with the contralateral side (P cell phones for more than 10 years presented higher differences between IL-10 levels in ipsilateral versus contralateral parotids (P = 0.0012). No difference was observed in any of the tested parameters in correlation with cell phone monthly usage in minutes. The exposure of parotid glands to cell phones can alter salivary IL-10 and IL-1β levels, consistent with a pro-inflammatory microenvironment that may be related to heat production. © 2016 John Wiley & Sons A/S.

    Inattention to the roadway, including cell phone use while driving (cell phone calls, sending and reading texts, mobile app use, and Internet use), is a critical problem for teen drivers and increases risk for crashes. Effective behavioral interventions for teens are needed in order to decrease teen driver inattention related to cell phone use while driving. However, teens' perceptions of mobile device use while driving is a necessary component for theoretically driven behavior change interventions. The purpose of this study was to describe teen drivers' perceptions of cell phone use while driving in order to inform future interventions to reduce risky driving. We conducted 7 focus groups with a total of 30 teen drivers, ages 16-18, licensed for ≤ 1 year in Pennsylvania. The focus group interview guide and analysis were based on the Theory of Planned Behavior, identifying the attitudes, perceived behavioral control, and norms about inattention to the roadway. Directed descriptive content analysis was used to analyze the focus group interviews. All focus groups were coded by 2 research team members and discrepancies were reconciled. Themes were developed based on the data. Teens had a mean age of 17.39 (SD = 0.52), mean length of licensure of 173.7 days (SD = 109.2; range 4-364), were 50% male and predominately white (90%) and non-Hispanic (97%). From the focus group data, 3 major themes emerged: (1) Recognizing the danger but still engaging; (2) Considering context; and (3) Formulating safer behaviors that might reduce risk. Despite recognizing that handheld cell phone use, texting, and social media app use are dangerous and distracting while driving, teens and their peers often engaged in these behaviors. Teens described how the context of the situation contributed to whether a teen would place or answer a call, write or respond to a text, or use a social media app. Teens identified ways in which they controlled their behaviors, although some still drew

    Objective: To explore the effects of radiation of cellular phone on the growth of cells. Methods: A radiation cycle was designed as working 25 minutes and then resting for 5 minutes for cellular phone. The Mark145 cell bottles were divided into six groups. The first two groups were radiated for two cycles, and the second two groups for four cycles, and the third two groups for five cycles. Each two groups were put 10cm far away from cellular phone and attach to it separately. Results: After culturing for 3 days there are many dead cells in the bottles. After culturing for 6 days, there is few living cells. Conclusions: cellular phone radiation is fatal to Mark145 cells, and the quantity of the dead cells change with the radiation time and the distance to radiation. That is to say, with the prolonging of radiation time and the shortening of the distance, the quantity of the dead cells is increasing. (authors)

    Some concern has arisen about adverse health effects of cell phones, especially the possibility that the low power microwave-frequency signal transmitted by the antennas on handsets might cause brain tumors or accelerate the growth of subclinical tumors. We analyzed data from the Statistical Report: Primary Brain Tumors in the United States, 2000-2004 and 2007 cell phone subscription data from the Governing State and Local Sourcebook. There was a significant correlation between number of cell phone subscriptions and brain tumors in nineteen US states (r = 0.950, P cell phone subscriptions and brain tumors could be due solely to the fact that some states, such as New York, have much larger populations than other states, such as North Dakota, multiple linear regression was performed with number of brain tumors as the dependent variable, cell phone subscriptions, population, mean family income and mean age as independent variables. The effect of cell phone subscriptions was significant (P = 0.017), and independent of the effect of mean family income (P = 0.894), population (P = 0.003) and age (0.499). The very linear relationship between cell phone usage and brain tumor incidence is disturbing and certainly needs further epidemiological evaluation. In the meantime, it would be prudent to limit exposure to all sources of electro-magnetic radiation.

  17. Cancer risks related to low-level RF/MW exposures, including cell phones.

    2013-09-01

    For years, radiofrequency (RF) and microwave (MW) radiations have been applied in the modern world. The rapidly increasing use of cellular phones called recent attention to the possible health risks of RF/MW exposures. In 2011, a group of international experts organized by IARC (International Agency for Research on Cancer in Lyon) concluded that RF/MW radiations should be listed as a possible carcinogen (group 2B) for humans. Three meta-analyses of case-control studies have concluded that using cell phones for more than ten years was associated with an increase in the overall risk of developing a brain tumor. The Interphone Study, the largest health-related case-control international study of use of cell phones and head and neck tumors, showed no statistically significant increases in brain cancers related to higher amounts of cell phone use, but excess risk in a small subgroup of more heavily exposed users associated with latency and laterality was reported. So far, the published studies do not show that mobile phones could for sure increase the risk of cancer. This conclusion is based on the lack of a solid biological mechanism, and the fact that brain cancer rates are not going up significantly. However, all of the studies so far have weaknesses, which make it impossible to entirely rule out a risk. Mobile phones are still a new technology and there is little evidence about effects of long-term use. For this reason, bioelectromagnetic experts advise application of a precautionary resources. It suggests that if people want to use a cell phone, they can choose to minimize their exposure by keeping calls short and preferably using hand-held sets. It also advises discouraging children from making non essential calls as well as also keeping their calls short.

    Fluorescent microscopy and flow cytometry are widely used tools in biomedical research and clinical diagnosis. However these devices are in general relatively bulky and costly, making them less effective in the resource limited settings. To potentially address these limitations, we have recently demonstrated the integration of wide-field fluorescent microscopy and imaging flow cytometry tools on cell-phones using compact, light-weight, and cost-effective opto-fluidic attachments. In our flow cytometry design, fluorescently labeled cells are flushed through a microfluidic channel that is positioned above the existing cell-phone camera unit. Battery powered light-emitting diodes (LEDs) are butt-coupled to the side of this microfluidic chip, which effectively acts as a multi-mode slab waveguide, where the excitation light is guided to uniformly excite the fluorescent targets. The cell-phone camera records a time lapse movie of the fluorescent cells flowing through the microfluidic channel, where the digital frames of this movie are processed to count the number of the labeled cells within the target solution of interest. Using a similar opto-fluidic design, we can also image these fluorescently labeled cells in static mode by e.g. sandwiching the fluorescent particles between two glass slides and capturing their fluorescent images using the cell-phone camera, which can achieve a spatial resolution of e.g. - 10 μm over a very large field-of-view of - 81 mm(2). This cell-phone based fluorescent imaging flow cytometry and microscopy platform might be useful especially in resource limited settings, for e.g. counting of CD4+ T cells toward monitoring of HIV+ patients or for detection of water-borne parasites in drinking water.

    Children today are exposed to cell phones early in life, and may be the most vulnerable if exposure is harmful to health. We investigated the association between cell phone use and hearing loss in children. The Danish National Birth Cohort (DNBC) enrolled pregnant women between 1996 and 2002. Detailed interviews were conducted during gestation, and when the children were 6 months, 18 months and 7 years of age. We used multivariable-adjusted logistic regression, marginal structural models (MSM) with inverse-probability weighting, and doubly robust estimation (DRE) to relate hearing loss at age 18 months to cell phone use at age 7 years, and to investigate cell phone use reported at age 7 in relation to hearing loss at age 7. Our analyses included data from 52 680 children. We observed weak associations between cell phone use and hearing loss at age 7, with odds ratios and 95% confidence intervals from the traditional logistic regression, MSM and DRE models being 1.21 [95% confidence interval [CI] 0.99, 1.46], 1.23 [95% CI 1.01, 1.49] and 1.22 [95% CI 1.00, 1.49], respectively. Our findings could have been affected by various biases and are not sufficient to conclude that cell phone exposures have an effect on hearing. This is the first large-scale epidemiologic study to investigate this potentially important association among children, and replication of these findings is needed. © 2013 Blackwell Publishing Ltd.

This study performed to determine the thermal changes due to mobile phone radio frequency waves in gray and white brain tissue. Methods: This study is an empirical study, where the thermal changes of electromagnetic waves resulted from cell phones (900 MHZ, specific absorption rate for head 1.18 w/kg on the 15 brain tissue of a cow were analyzed in a compartment with three different thickness of 2 mm, 12 mm, and 22 mm, for 15 min. The Lutron thermometer (model: MT-917 with 0.01°C precision was used for measuring the tissue temperature. For each thickness was measured three times. Data analysis is done by Lutron and MATLAB software packages. Results: In confronting of the tissue with the cell phone, the temperature was increased by 0.53°C in the 2 mm thickness that is the gray matter of the brain, increased by 0.99°C in the 12 mm thickness, and also increased by 0.92°C in the 22 mm thickness. Brain temperature showed higher rates than the base temperature after 15 min of confrontation with cell phone waves in all the three thicknesses. Conclusions: Cell phone radiated radio frequency waves were effective on increasing brain tissue temperature, and this temperature increase has cumulative effect on the tissue, being higher, for some time after the confrontation than the time with no confrontation.

    The first research objective was to replicate the finding of Leiter et al. [(2008)Journal of Nursing Management, 16, 100-109.] of Generation X nurses (n=338) reporting higher levels of distress than Baby Boomer nurses (n=139). The second objective was to test whether Generation X nurses reported more negative social environments at work than did Baby Boomer nurses. Negative social environments can influence the quality of work and the experience of distress for nurses. Generational differences in the experience of distress and collegiality have implications for the establishment of healthy workplaces, recruitment and retention. A questionnaire survey of nurses was organized by generation. Analyses of variance contrasted the scores on burnout, turnover intention, physical symptoms, supervisor incivility, coworker incivility and team civility. The results confirmed the hypotheses of Generation X nurses reporting more negative experiences than did Baby Boomer nurses on all measures. The negative quality of social encounters at work contributes to nurses' experience of distress and suggest conflicts of values with the dominant culture of their workplaces. Proactive initiatives to enhance the quality of collegiality can contribute to retention strategies. Building collegiality across generations can be especially useful. © 2010 The Authors.

    Magnetic levitation has emerged as a technique that offers the ability to differentiate between cells with different densities. We have developed a magnetic levitation system for this purpose that distinguishes not only different cell types but also density differences in cells of the same type. This small-scale system suspends cells in a paramagnetic medium in a capillary placed between two rare earth magnets, and cells levitate to an equilibrium position determined solely by their density. Uniform reference beads of known density are used in conjunction with the cells as a means to quantify their levitation positions. In one implementation images of the levitating cells are acquired with a microscope, but here we also introduce a cell phone-based device that integrates the magnets, capillary, and a lens into a compact and portable unit that acquires images with the phone's camera. To demonstrate the effectiveness of magnetic levitation in cell density analysis we carried out levitation experiments using red blood cells with artificially altered densities, and also levitated those from donors. We observed that we can distinguish red blood cells of an anemic donor from those that are healthy. Since a plethora of disease states are characterized by changes in cell density magnetic cell levitation promises to be an effective tool in identifying and analyzing pathologic states. Furthermore, the low cost, portability, and ease of use of the cell phone-based system may potentially lead to its deployment in low-resource environments.

The current spread of mobile phone-embedded cameras offers new opportunities for recording food intake. Moreover, the act of taking pictures of food consumed may enhance visual consciousness of food choice and quantity. The present study aimed to assess the effect of using cell phone pictures to record food intake on energy intake and food choice in college students. The effectiveness and acceptability of cell phone picture-based diet recording also was assessed. A repeated measures crossover design was used. One group of participants entered their food intake online during 3 days based on their memory, although a second group recorded their food intake using cell phone pictures as their reference. Participants then crossed over to complete 3 more days of diet recording using the alternate method. Focus groups were conducted to obtain feedback on the effectiveness and acceptability of cell phone picture-based diet recording. Intake of meat and vegetable servings were significantly higher in the memory period compared with the cell phone period, regardless of the order. Results from the focus group indicated a positive attitude toward the use of cell phone pictures in recording food intake and an increased awareness of food choice and portion size. Cell phone pictures may be an easy, relevant, and accessible method of diet self-monitoring when aiming at dietary changes. Future trials should combine this technique with healthy eating education. © 2015 Sigma Theta Tau International.

    Full Text Available The evaluation of disposable lab-on-a-chip (LOC devices on cell phones is an attractive alternative to migrate the analytical strength of LOC solutions to decentralized sensing applications. Imaging the micrometric detection areas of LOCs in contact with intact phone cameras is central to provide such capability. This work demonstrates a disposable and morphing liquid lens concept that can be integrated in LOC devices and refocuses micrometric features in the range necessary for LOC evaluation using diverse cell phone cameras. During natural evaporation, the lens focus varies adapting to different type of cameras. Standard software in the phone commands a time-lapse acquisition for best focal selection that is sufficient to capture and resolve, under ambient illumination, 50 μm features in regions larger than 500 × 500 μm2. In this way, the present concept introduces a generic solution compatible with the use of diverse and unmodified cell phone cameras to evaluate disposable LOC devices.

    The pervasive use of cell phones impacts many people-both cell phone users and bystanders exposed to conversations. This study examined the effects of overhearing a one-sided (cell phone) conversation versus a two-sided conversation on attention and memory. In our realistic design, participants were led to believe they were participating in a study examining the relationship between anagrams and reading comprehension. While the participant was completing an anagram task, the researcher left the room and participants overheard a scripted conversation, either two confederates talking with each other or one confederate talking on a cell phone. Upon the researcher's return, the participant took a recognition memory task with words from the conversation, and completed a questionnaire measuring the distracting nature of the conversation. Participants who overheard the one-sided conversation rated the conversation as significantly higher in distractibility than those who overheard the two-sided conversation. Also, participants in the one-sided condition scored higher on the recognition task. In particular they were more confident and accurate in their responses to words from the conversation than participants in the two-sided condition. However, participants' scores on the anagram task were not significantly different between conditions. As in real world situations, individual participants could pay varying amounts of attention to the conversation since they were not explicitly instructed to ignore it. Even though the conversation was irrelevant to the anagram task and contained less words and noise, one-sided conversations still impacted participants' self-reported distractibility and memory, thus showing people are more attentive to cell phone conversations than two-sided conversations. Cell phone conversations may be a common source of distraction causing negative consequences in workplace environments and other public places.

    Problematic cell phone use has alarmingly increased in industrialized countries in the past 10 years. For many perpetrators, it can turn into a behavioural addiction, although this is not a recognized medical condition. Although there are many tools for evaluating this use, one of the most widely used tools is the Mobile Phone Problematic Use Scale (MPPUS), which we test on a representative sample of the population in Spain to obtain an estimate of the prevalence of problematic cell phone use in our midst. The age range consists of 16–65 years, with 1,126 surveys conducted. In this population, we verify that the reliability and internal consistency of the MPPUS (α = 0.939) are maintained. Additionally, the construct validity, considering the derived factors (Abuse and Dependence, Craving and Loss of Control, and Dependence on the Social Environment) are aligned with other research and with diverse external criteria of addiction. We establish four categories of users (Casual, Regular, At Risk, and Problematic) and obtain a prevalence of 15.4% among At Risk Users and 5.1% among Problematic Users. This finding implies a total of 20.5% of Users with Problems. A binary logistic regression analysis shows that age, gender, level of education, and daily cell phone use predict problematic cell phone use. The results, based on multiple criteria, show that such problematic use shares features of recognized addictions, affecting large segments of the population and not only adolescents. PMID:28771626

    Constant exposure to radio frequency signals from mobile phones and their base stations could adversely affect on human health. As a consequence, as a result of this impact it is appeared frequent headaches, loss of memory and concentration, tension in the eardrum and sudden bouts of fatigue, childhood leukemia, brain tumors, eye cataracts, cardiovascular diseases, disorders of the nervous system. Some people suffer from hyperelectrosensitivity. It should be noted that the analog phones much more harmful to human health than digital ones. Radio frequency of electromagnetic fields which is used by a modern cellular communications is in the range from 450 MHz to 1.9 GHz. Such fields unlike to ionizing radiation can not cause secondary radioactivity in the body. The cell phone is a device having a potential danger to health, so it is advisable wherever possible to protect yourselves from its use, or at least to minimize its use

    Full Text Available Students of science traditionally make 3x5 flash cards to assist learning nomenclature, structures, and reactions. Advances in educational technology have enabled flashcards viewed on computers, offering an endless array of drilling and feedback opportunities for students. The current generation of students is less inclined to use computers, but they use their cell phones 24 hours a day. This report outlines these trends and an even more recent educational technology initiative, that of using cell phone flash cards to help students learn biology and chemistry nomenclature, structures, and reactions. Students responded positively to cell phone flash cards in a pilot study and a more detailed study is planned for the coming year.

    Cell phone use is considered as an essential part of everyday life saturating all age groups and demographics. This study aimed to explore the effect of various cell phone functions on postural control and mobility in the elderly. Twenty healthy older (mean age 72.5±2.9) and twenty young (26.3±2.8) adults participated in this study. Postural balance was assessed by measuring the center of pressure (CoP) displacement with (talking on a cell phone (CONVERSE), dialing a number (DIAL) and listening to music (MUSIC)) and without cell phone use. Mobility was assessed by the Timed Up and Go Test (TUGT). Results showed that for both groups, the CoP parameters increased significantly during the CONVERSE (pcell phone use impairs similarly standing postural balance of elderly and young adults. Interestingly, in the elderly, all cell phone functions used altered mobility with the dialing function causing the largest mobility deterioration. Copyright © 2017 Elsevier Inc.

    We prospectively examined trends in cell phone use among children in the Danish National Birth Cohort. Cell phone use was assessed at ages 7 and 11 years, and we examined use patterns by age, by year of birth, and in relation to specific individual characteristics. There was an increase in cell phone use from age 7 (37%) to 11 years (94%). There was a clear pattern of greater reported cell phone use among children at age 7 years with later birth year, but this trend disappeared at age 11. Girls and those who used phones at age 7 talked more often and for longer durations at age 11 years. Low socio-economic status and later year of birth were associated with voice calls at age 7 but not at age 11 years. At age 11 most used cell phones for texting and gaming more than for voice calls. Further, children who started using cell phones at age 7 years were more likely to be heavy cell phone voice users at age 11 years, making early use a marker for higher cumulative exposure regardless of year of birth. As cell phone technology continues to advance, new use patterns will continue to emerge, and exposure assessment research among children must reflect these trends.

    Research about prenatal exposure to electromagnetic fields from cell phones among expectant parents and reproductive outcome is limited. The aim of this article is to investigate the association between pregnancy outcome and parental cell phone exposure in a large prospective study. The study was based on the Norwegian Mother and Child Cohort Study conducted during the decade 1999-2009. In that study, pregnant women were recruited before a routine ultrasound examination during gestational week 15; they answered a questionnaire at that time and again around gestational week 30. The expectant father was invited to answer a questionnaire during gestational week 15 (2001-2009). The forms contained questions regarding cell phone use. The response rate was 38.7% and the cohort comprised 100,730 singleton births. Pregnancy outcomes were obtained by linkage to the Medical Birth Registry of Norway. The risk of preeclampsia was slightly lower among women with medium and high cell phone exposure compared with low exposure after adjusting for potential confounders. Fathers with testis exposure when using cell phones had a borderline increased risk of perinatal mortality among offspring and a slightly decreased risk of partner developing preeclampsia during pregnancy compared with no cell phone exposure of head or testis. None of the other pregnancy outcomes was associated with cell phone exposure. We found no association between maternal prenatal or paternal preconceptional cell phone exposure and any of the studied pregnancy outcomes. The only risk estimate suggesting a potential increased risk was not consistent with other findings.

    Cell phone use behaviors are known to vary across demographic sub-groups and geographic locations. This study examined whether universal hand-held calling while driving bans were associated with lower road-side observed hand-held cell phone conversations across drivers of different ages (16-24, 25-59, ≥60 years), sexes, races (White, African American, or other), ruralities (suburban, rural, or urban), and regions (Northeast, Midwest, South, and West). Data from the 2008-2013 National Occupant Protection Use Survey were merged with states' cell phone use while driving legislation. The exposure was presence of a universal hand-held cell phone ban at time of observation. Logistic regression was used to assess the odds of drivers having a hand-held cell phone conversation. Sub-groups differences were assessed using models with interaction terms. When universal hand-held cell phone bans were effective, hand-held cell phone conversations were lower across all driver demographic sub-groups and regions. Sub-group differences existed among the sexes (p-value, phone bans, the adjusted odds ratio (aOR) of a driver hand-held phone conversation was 0.34 [95% confidence interval (CI): 0.28, 0.41] for females versus 0.47 (CI 0.40, 0.55) for males and 0.31 (CI 0.25, 0.38) for drivers in Western states compared to 0.47 (CI 0.30, 0.72) in the Northeast and 0.50 (CI 0.38, 0.66) in the South. The presence of universal hand-held cell phone bans were associated lower hand-held cell phone conversations across all driver sub-groups and regions. Hand-held phone conversations were particularly lower among female drivers and those from Western states when these bans were in effect. Public health interventions concerning hand-held cell phone use while driving could reasonably target all drivers.

    Cell-phone use impairs driving safety and performance. This impairment may stem from the remote partner's lack of awareness about the driving situation. In this study, pairs of participants completed a driving simulator task while conversing naturally in the car and while talking on a hands-free cell phone. In a third condition, the driver drove while the remote conversation partner could see video of both the road ahead and the driver's face. We tested the extent to which this additional visual information diminished the negative effects of cell-phone distraction and increased situational awareness. Collision rates for unexpected merging events were high when participants drove in a cell-phone condition but were reduced when they were in a videophone condition, reaching a level equal to that observed when they drove with an in-car passenger or drove alone. Drivers and their partners made shorter utterances and made longer, more frequent traffic references when they spoke in the videophone rather than the cell-phone condition. Providing a view of the driving scene allows remote partners to help drivers by modulating their conversation and referring to traffic more often. © The Author(s) 2014.

    Many driving simulator studies have shown that cell phone use while driving greatly degraded driving performance. In terms of safety analysis, many factors including drivers, vehicles, and driving situations need to be considered. Controlled or simulated studies cannot always account for the full effects of these factors, especially situational factors such as road condition, traffic density, and weather and lighting conditions. Naturalistic driving by its nature provides a natural and realistic way to examine drivers' behaviors and associated factors for cell phone use while driving. In this study, driving speed while using a cell phone (conversation or visual/manual tasks) was compared to two baselines (baseline 1: normal driving condition, which only excludes driving while using a cell phone, baseline 2: driving-only condition, which excludes all types of secondary tasks) when traversing an intersection. The outcomes showed that drivers drove slower when using a cell for both conversation and visual/manual (VM) tasks compared to baseline conditions. With regard to cell phone conversations, drivers were more likely to drive faster during the day time compared to night time driving and drive slower under moderate traffic compared to under sparse traffic situations. With regard to VM tasks, there was a significant interaction between traffic and cell phone use conditions. The maximum speed with VM tasks was significantly lower than that with baseline conditions under sparse traffic conditions. In contrast, the maximum speed with VM tasks was slightly higher than that with baseline driving under dense traffic situations. This suggests that drivers might self-regulate their behavior based on the driving situations and demand for secondary tasks, which could provide insights on driver distraction guidelines. With the rapid development of in-vehicle technology, the findings in this research could lead the improvement of human-machine interface (HMI) design as well

    To present our experience with "smart phones" when examining and documenting human eyes. From September to October 2013 fifteen patients (8 men, 7 women) eye fundus was examined, an average age during the examination was 58 year (ranging from 20-65 years). The photo-documentation was performed with dilated pupils (tropicamid hydrochloridum 1% eye drops) with mobile phone Samsung Galaxy Nexus with the operating system Android 4.3 (Google Inc., Mountain View, CA, USA) and iPhone 4 with the operating system 7.0.4 (Apple Inc., Loop Cupertino, CA, USA), and with 20D lens (Volk Optical Inc., Mentor, OH, USA). The images of the retina taken with a mobile phone and the spherical lens are of a very good quality, precise and reproducible. Learning this technique is easy and fast, the learning curve is steep. Photo-documentation of retina with a mobile phone is a safe, time-saving, easy-to-learn technique, which may be used in a routine ophthalmologic practice. The main advantage of this technique is availability, small size and easy portability of the devices.

    2015-01-01

    Blood analysis is one of the most important clinical tests for medical diagnosis. Flow cytometry and optical microscopy are widely used techniques to perform blood analysis and therefore cost-effective translation of these technologies to resource limited settings is critical for various global health as well as telemedicine applications. In this chapter, we review our recent progress on the integration of imaging flow cytometry and fluorescent microscopy on a cell phone using compact, light-weight and cost-effective opto-fluidic attachments integrated onto the camera module of a smartphone. In our cell-phone based opto-fluidic imaging cytometry design, fluorescently labeled cells are delivered into the imaging area using a disposable micro-fluidic chip that is positioned above the existing camera unit of the cell phone. Battery powered light-emitting diodes (LEDs) are butt-coupled to the sides of this micro-fluidic chip without any lenses, which effectively acts as a multimode slab waveguide, where the excitation light is guided to excite the fluorescent targets within the micro-fluidic chip. Since the excitation light propagates perpendicular to the detection path, an inexpensive plastic absorption filter is able to reject most of the scattered light and create a decent dark-field background for fluorescent imaging. With this excitation geometry, the cell-phone camera can record fluorescent movies of the particles/cells as they are flowing through the microchannel. The digital frames of these fluorescent movies are then rapidly processed to quantify the count and the density of the labeled particles/cells within the solution under test. With a similar opto-fluidic design, we have recently demonstrated imaging and automated counting of stationary blood cells (e.g., labeled white blood cells or unlabeled red blood cells) loaded within a disposable cell counting chamber. We tested the performance of this cell-phone based imaging cytometry and blood analysis platform

    Reid, Donna J; Reid, Fraser J M

    2007-06-01

    This paper investigates whether social anxiety and loneliness lead to contrasting beliefs and preferences among cell phone users towards texting and talking on their cell phones. Three hypotheses are examined: (1) that social anxiety and loneliness are differentially associated with generalized preferences either for texting or for talking on the cell phone, (2) that these preferences are linked to contrasting beliefs concerning the social functionality of the short message service (SMS), and (3) that these divergent beliefs mediate the effects of social anxiety and loneliness on cell phone users' generalized preferences for texting or talking. Results from an Internet questionnaire (N=158) showed that, whilst lonely participants preferred making voice calls and rated texting as a less intimate method of contact, anxious participants preferred to text, and rated it a superior medium for expressive and intimate contact. These divergent beliefs accounted for 36% and 16% of the variance in preference for texting and voice calls, respectively, and significantly attenuated the influence of loneliness and social anxiety when they were added to the regression equations for these measures. Results are discussed in terms of the hyperpersonal possibilities of mobile communications technologies.

    Full Text Available Almost immediately after the Charlie Hebdo shootings of 7 January 2015, some print media made room for alternative opinions of what had happened. The articles and the discussions they inspired are replete with evaluations which lend themselves to analysis using methods and procedures of Politeness Theory. The paper examines an example of a metadiscourse of (impoliteness which questions the “moral orders” underlying the cartoonists’ as well as other participants’ social practices vis-à-vis their ideological foundations, esp. freedom of speech as one of the principal liberties of our society. To that end, the approach to politeness as “social practice” is employed which, while insisting on multiple understandings of politeness, places participants’ evaluations at the centre of politeness research.

    Full Text Available Abstract Background Cell phone use behaviors are known to vary across demographic sub-groups and geographic locations. This study examined whether universal hand-held calling while driving bans were associated with lower road-side observed hand-held cell phone conversations across drivers of different ages (16–24, 25–59, ≥60 years, sexes, races (White, African American, or other, ruralities (suburban, rural, or urban, and regions (Northeast, Midwest, South, and West. Methods Data from the 2008–2013 National Occupant Protection Use Survey were merged with states’ cell phone use while driving legislation. The exposure was presence of a universal hand-held cell phone ban at time of observation. Logistic regression was used to assess the odds of drivers having a hand-held cell phone conversation. Sub-groups differences were assessed using models with interaction terms. Results When universal hand-held cell phone bans were effective, hand-held cell phone conversations were lower across all driver demographic sub-groups and regions. Sub-group differences existed among the sexes (p-value, <0.0001 and regions (p-value, 0.0003. Compared to states without universal hand-held cell phone bans, the adjusted odds ratio (aOR of a driver hand-held phone conversation was 0.34 [95% confidence interval (CI: 0.28, 0.41] for females versus 0.47 (CI 0.40, 0.55 for males and 0.31 (CI 0.25, 0.38 for drivers in Western states compared to 0.47 (CI 0.30, 0.72 in the Northeast and 0.50 (CI 0.38, 0.66 in the South. Conclusions The presence of universal hand-held cell phone bans were associated lower hand-held cell phone conversations across all driver sub-groups and regions. Hand-held phone conversations were particularly lower among female drivers and those from Western states when these bans were in effect. Public health interventions concerning hand-held cell phone use while driving could reasonably target all drivers.

    Full Text Available Introduction: Legislation systems of most countries prohibited using the handheld mobile phone while driving due to the fact that it disturbs concentration and causes hand involvement. Every phone owner is accustomed to the ringtone of his phone and almost involuntarily endeavors to pick it up or check who calls. This engages one’s psychomotor skills, which in our opinion contributes to the attenuation of reaction time needed for performing other crucial functions. Objectives: The aim of the study was: (1 to evaluate the infl uence of the sound of a ringing mobile phone on the complex reaction time (RT score in healthy subjects (owners, and (2 to check if there are any differences in RT when a landline phone and mobile phone ring. Methods: To assess RT we used our system and protocol of examination, previously validated. The examination conditions were standardized. All tests were performed in the same room with the same light and general acoustic conditions. The test group consisted of 23 women and 24 men, aged 19–24 years. The examination comprised 4 sessions: Training Session (TS during which the subjects were accustomed with the application and sample stimuli, Control Session (CS with no telephone ringing, Landline Session (LS with landline phone ringing, Mobile Session (MS with mobile phone ringing. Results: The median RT in the study population was signifi cantly elongated (p 0.05. Conclusions: We think that the specifi c ‘bond’ between a person and their private phone can signifi cantly disrupt their attention and thus affect the attention-demanding activities.

  4. The Relationship Between Cell Phone Use and Academic Performance in a Sample of U.S. College Students

    Full Text Available The cell phone is ever-present on college campuses and is frequently used in settings where learning occurs. This study assessed the relationship between cell phone use and actual college grade point average (GPA after controlling for known predictors. As such, 536 undergraduate students from 82 self-reported majors at a large, public university were sampled. A hierarchical regression (R2 = .449 demonstrated that cell phone use was significantly (p < .001 and negatively (β = −.164 related to actual college GPA after controlling for demographic variables, self-efficacy for self-regulated learning, self-efficacy for academic achievement, and actual high school GPA, which were all significant predictors (p < .05. Thus, after controlling for other established predictors, increased cell phone use was associated with decreased academic performance. Although more research is needed to identify the underlying mechanisms, findings suggest a need to sensitize students and educators about the potential academic risks associated with high-frequency cell phone use.

  5. Do cell phones, iPods/MP3 players, siblings and friends matter? Predictors of child body mass in a U.S. Southern Border City Middle School.

    This study examines the association of children's (i) micro-social environment, specifically siblings [kin-friends] and friends from school and neighborhood [non-kin-friends], and (ii) ownership of information and communication technologies (ICT), specifically cell phones and iPod/MP3 players, with body mass index percentile (BMIp). Fifty-five randomly selected 6th graders with a mean age of 12 years, stratified by gender (23 boys and 32 girls), from a Texas middle school located in a city along the U.S. southern border. The linear regression of BMIp on number of siblings and of non-kin-friends, and ownership of cell phone and of iPod/MP3 player was examined using two models: M1 was based on the manual selection of predictors from a pool of potential predictors. M2 was derived from the predictors specified in M1 using backward elimination technique. Because sample size was small, the significance of regression coefficients was evaluated using robust standard errors to calculate t-values. Data for predictors were obtained through a survey. Height and weight were obtained through actual anthropometric measurements. BMIp was calculated using the on-line BMI calculator of the Center for Disease Control and Prevention. Findings reveal that children's social environment and ICT ownership predict BMIp; specifically, number of siblings (M2: β = -0.34, p-value MP3 players (M2: β = 0.33, p-value < .001). These results underscore the importance of family in configuring, and of new personal technical devices (that encourage solitary, and oftentimes sedentary, activities) in predicting child body mass. © 2012 Asian Oceanian Association for the Study of Obesity .

    Epidemiological and experimental evidence for detrimental effects of cell phone use on semen quality is still equivocal. And that recruiting participants from infertility clinic not from general population may raise the possibility of a selection bias. To investigate effects of cell phone use on semen parameters in a general population,We screened and documented the cell phone use information of 794 young men from the Male Reproductive Health in Chongqing College students (MARHCS) cohort study in 2013, followed by 666 and 568 in 2014 and 2015, respectively. In the univariate regression analyses, we found that the daily duration of talking on the cell phone was significantly associated with decreased semen parameters, including sperm concentration [β coefficient=-6.32% per unit daily duration of talking on the cell phone (h); 95% confidence interval (CI), -11.94, -0.34] and total sperm count (-8.23; 95% CI, -14.38, -1.63) in 2013; semen volume (-8.37; 95% CI, -15.93, -0.13) and total sperm count (-16.59; 95% CI, -29.91, -0.73) in 2015]. Internet use via cellular networks was also associated with decreased sperm concentration and total sperm counts in 2013 and decreased semen volume in 2015. Multivariate analyses were used to adjust for the effects of potential confounders, and significant negative associations between internet use and semen parameters remained. Consistent but nonsignificant negative associations between talking on the cell phone and semen parameters persisted throughout the three study years, and the negative association was statistically significant in a mixed model that considered all three years of data on talking on the cell phone and semen quality. Our results showed that certain aspects of cell phone use may negatively affect sperm quality in men by decreasing the semen volume, sperm concentration, or sperm count, thus impairing male fertility.

    The risks and opportunities associated with the use of technologies are of growing research interest. Patterns of technology usage illuminate these opportunities and risks. However, no studies have assessed the usage patterns (frequency, duration, and intensity) and related factors in young people with intellectual disabilities. Questionnaires on Internet and cell phone usage patterns, the Internet Over-Use Scale and the Cell-Phone Over-Use Scale, as well as the Beck Depression Inventory were filled out in one-on-one interviews of 216 youth with intellectual disabilities. Young people with disabilities make more social and recreational rather than educational use of these tools, and show higher rates of excessive use of both technologies than a comparison group of 410 young people without disabilities. Also, their overuse is associated with other unhealthy behaviors. The framework of support needs of people with disabilities should be considered to promote healthy Internet and cell phone use. © 2017 John Wiley & Sons Ltd.

    2011-04-01

    Moving a brain-computer interface (BCI) system from a laboratory demonstration to real-life applications still poses severe challenges to the BCI community. This study aims to integrate a mobile and wireless electroencephalogram (EEG) system and a signal-processing platform based on a cell phone into a truly wearable and wireless online BCI. Its practicality and implications in a routine BCI are demonstrated through the realization and testing of a steady-state visual evoked potential (SSVEP)-based BCI. This study implemented and tested online signal processing methods in both time and frequency domains for detecting SSVEPs. The results of this study showed that the performance of the proposed cell-phone-based platform was comparable, in terms of the information transfer rate, with other BCI systems using bulky commercial EEG systems and personal computers. To the best of our knowledge, this study is the first to demonstrate a truly portable, cost-effective and miniature cell-phone-based platform for online BCIs.

    2014-06-01

    The effects of cell phone use and safety belt use have been an important focus of research related to driver safety. Cell phone use has been shown to be a significant source of driver distraction contributing to substantial degradations in driver performance, while safety belts have been demonstrated to play a vital role in mitigating injuries to crash-involved occupants. This study examines the prevalence of cell phone use and safety belt non-use among the driving population through direct observation surveys. A bivariate probit model is developed to simultaneously examine the factors that affect cell phone and safety belt use among motor vehicle drivers. The results show that several factors may influence drivers' decision to use cell phones and safety belts, and that these decisions are correlated. Understanding the factors that affect both cell phone use and safety belt non-use is essential to targeting policy and programs that reduce such behavior. Copyright © 2014 Elsevier Ltd.

    2012-01-01

    Recent studies have shown that exposing human semen samples to cell phone radiation leads to a significant decline in sperm parameters. In daily living, a cell phone is usually kept in proximity to the groin, such as in a trouser pocket, separated from the testes by multiple layers of tissue. The aim of this study was to calculate the distance between cell phone and semen sample to set up an in vitro experiment that can mimic real life conditions (cell phone in trouser pocket separated by multiple tissue layers). For this reason, a computational model of scrotal tissues was designed by considering these separating layers, the results of which were used in a series of simulations using the Finite Difference Time Domain (FDTD) method. To provide an equivalent effect of multiple tissue layers, these results showed that the distance between a cell phone and semen sample should be 0.8 cm to 1.8 cm greater than the anticipated distance between a cell phone and the testes.

    2012-02-01

    The purpose of this research was to evaluate the effects of a cognitive training and cell phone intervention on the recidivism of 70 juvenile offenders. Median days to rearrest were 106 for the control group, 191 for the class-only group, and 278 for the class plus cell phone group. Using rearrest as the survival criterion, the survival ratios of the class-only and class plus cell phone groups were 2.64 and 2.94 times longer than the control group, respectively. After controlling for gender, prior arrests, and risk score, the Poisson regression indicated that the class-only and class plus cell phone groups were 51% lower in total arrests than the control group. These results suggest that cognitive training supplemented with a cell phone coach is an effective and cost-efficient intervention for reducing recidivism.

  12. I-TNT: PHONE NUMBER EXPANSION AND TRANSLATION SYSTEM FOR MANAGING INTERCONNECTIVITY ADDRESSING IN SIP PEERING

    2015-02-01

    Full Text Available Voice over IP (VoIP subscribers is growing vastly in the recent years due to the ever increase in smartphones, 3G, WiFi, etc. This growth leads the VoIP service providers to peer with each other through Session Initiation Protocol (SIP peering for low/free cost of voice communication. Naturally, this growth is not without challenges, especially in phone addressing. This paper proposes an I-TNT (Infrastructure-Phone Number Translation numbering system to expand the range of the existing E.164 numbers and mapping between private and public number at the edge of the signalling path. As a result, I-TNT numbering system is successfully implemented and able to allocate the expanded phone numbers to end-users in one service provider.

    Workplace incivility (WI) continues to hamper professional nursing practice, patient care, and the health of nurses who encounter this phenomenon in their workplace. This article provides an exemplar of WI experienced by a new nurse when a more seasoned nurse uses humiliation, intimidation, and angry verbal abuse to accuse the novice nurse in the presence of coworkers and patients that she failed to provide essential nursing care to a challenging patient. Nurses are reminded that open communication among coworkers will help minimize the occurrence of WI, encourage a supportive milieu in the unit, and ensure the safety of patients, family, and staff.

  16. A forecasting method to reduce estimation bias in self-reported cell phone data.

    Science.gov (United States)

    Redmayne, Mary; Smith, Euan; Abramson, Michael J

    2013-01-01

    There is ongoing concern that extended exposure to cell phone electromagnetic radiation could be related to an increased risk of negative health effects. Epidemiological studies seek to assess this risk, usually relying on participants' recalled use, but recall is notoriously poor. Our objectives were primarily to produce a forecast method, for use by such studies, to reduce estimation bias in the recalled extent of cell phone use. The method we developed, using Bayes' rule, is modelled with data we collected in a cross-sectional cluster survey exploring cell phone user-habits among New Zealand adolescents. Participants recalled their recent extent of SMS-texting and retrieved from their provider the current month's actual use-to-date. Actual use was taken as the gold standard in the analyses. Estimation bias arose from a large random error, as observed in all cell phone validation studies. We demonstrate that this seriously exaggerates upper-end forecasts of use when used in regression models. This means that calculations using a regression model will lead to underestimation of heavy-users' relative risk. Our Bayesian method substantially reduces estimation bias. In cases where other studies' data conforms to our method's requirements, application should reduce estimation bias, leading to a more accurate relative risk calculation for mid-to-heavy users.

    Poor sleep quality is closely associated with lifestyle habits including use of mobile cell-phones.This study aimed to identify the relationship between sleep quality due to abuse in mobile cell-phones and engagement in social networks. This cross-sectional study was conducted on 380 undergraduate students selected by proportional stratified sampling in Qom, Iran in 2015. Data were collected by two standard questionnaire including Cell-Phone Over-Use Scale (COS) and Pittsburgh sleep quality questionnaire beside the status of usage in cell-phone social networks. T-test, chi-square, Pearson correlation coefficient and multivariate logistic regression were used in data analysis. The mean age of participants was 21.8 ±3.2 yr, 69.1% were female, and 11.7% were married. The mean of COS and sleep quality scores were 48.18 ±17.5 and 5.38 ±2.31, respectively. The prevalence of over-use of cell phone was 10.7% (CI 0.95; 8.8%, 12.6%) and the prevalence of poor sleep quality was 61.7% (CI 0.95; 57.1%, 66.3%). The mean of all aspects and total score of sleep quality showed a direct significant association by cell-phone addiction score except sleep duration score that was inversely. Based on multivariate analysis affected to cell-phone addiction, being male gender and studying in general physician level are the most important predictors of poor sleep quality. Over use of internet and social networks via smart phones is related to poor sleep quality and quantity. Predefined sport programs, educational, cultural, and interesting entertainment are the essential needs for all medical students. These interventions are more important especially for male students who have longer educational.

    Slow motion video enhances our ability to perceive and experience the physical world. This can help students and teachers especially in cases of fast moving objects or detailed events that happen too quickly for the eye to follow. As often as possible, demonstrations should be performed by the students themselves and luckily many of them will already have this technology in their pockets. The "S" series of iPhone has the slow motion video feature standard, which also includes simultaneous sound recording (somewhat unusual among slow motion cameras). In this article I share some of my experiences using this feature and provide advice on how to successfully use this technology in the classroom.

    2013-01-01

    This iPhone application, Space Junk Sammy, is intended to be an educational application designed for Apple iPhones and iPads. This new concept educates kids in an innovative way about how orbital debris affects space missions. Orbital debris is becoming a very significant concern for NASA and all Earthorbiting space missions. Spacecraft in low-Earth orbit are in constant danger of being potentially damaged or destroyed by debris. High-profile spacecraft such as the International Space Station (ISS) and Hubble Space Telescope are dealing with orbital debris on a regular basis. Other basic educational concepts that are portrayed are low-Earth orbits, satellites, ISS, attitude control, and other facts that can be presented in betweenlevel popup screens. The Orbital Debris Cleanup game is relatively simple from the user s technical standpoint. It is a 2D game where the user s avatar is a satellite buddy, named Sammy, in orbit around Earth. Sammy is controlled by the user with the device s gyroscope as well as touchscreen controls. It has equipment used for taking care of the space debris objects on the screen. Sammy also has a claw, a laser deflector, and hydrazine rockets to grab or push the debris objects into a higher orbit or into a lower orbit to burn up in the Earth s atmosphere. The user interface shows Sammy and space debris objects constantly moving from left to right, where Sammy is trying to catch the debris objects before they move off the right side of the screen. Everything will be in constant motion to increase fun and add to the realism of orbiting the Earth. The satellite buddy is used to clean up the space debris and protect other satellites. Later levels will include a laser deflector and hydrazine rockets instead of a robotic claw to push the orbital debris into a higher orbit and out of the path of other satellites

    Full Text Available Background & objectives: The teratogenic effects of electromagnetic radiation on different processes of growth caused many concerns related to the harmful effects of cell-phone radiation on human health. Therefore, the aim of this study was to investigate the effects of cell-phone radiation on estrogen, progesterone, FSH and LH hormones together with dynastic sexual cells of adult female offspring of pregnant rats affected by these radiations. Methods: In this experimental study, 24 pregnant female rats divided into 3 groups including the control, sham and experimental groups were used. The control group received no radiation and the experimental group was exposed to cell-phone radiation at the beginning of pregnancy (4 hours daily for 14 days. The control group was exposed around turning-on cell-phone without conversation over the same period. After giving birth and after maturity, 10 female offsprings of different groups separated and after phlebotomizing, sexual hormones levels was measured and by separating the ovaries, ovarian follicles species were counted. The results analyzed using ANOVA and T tests. Differences in statistical analysis of data were considered significant at p<0.05. Results: The results showed that the pregnant female exposure to cell-phone radiation caused significant increase in the size and weight of the ovaries and atresic follicles (p<0.05 without significant effect on the number of primary and secondary follicles, antral, graph, primordial, corpus luteum and sexual hormones. Conclusion: Exposure to cell-phone radiations caused increase in the size, weight and atresic follicles of offspring’s ovaries in pregnant females

When connected to a network, though, they are capable of more than just picture taking: Suddenly, they gain access to the power of the cloud. We exploit this capability by providing a series of image-based personal advisory services. These are designed to work with any handset over any cellular carrier using commonly available Multimedia Messaging Service (MMS) and Short Message Service (SMS) features. Targeted at the unsophisticated consumer, these applications must be quick and easy to use, not requiring download capabilities or preplanning. Thus, all application processing occurs in the back-end system (i.e., as a cloud service) and not on the handset itself. Presenting an image to an advisory service in the cloud, a user receives information that can be acted upon immediately. Two of our examples involve color assessment - selecting cosmetics and home décor paint palettes; the third provides the ability to extract text from a scene. In the case of the color imaging applications, we have shown that our service rivals the advice quality of experts. The result of this capability is a new paradigm for mobile interactions - image-based information services exploiting the ubiquity of camera phones.

    Advances in medicine have largely followed advances in technology. Medical strides have been made when physicians and researchers have adapted growing science to target specific problems. A new medical field, telemedicine, has emerged that links physicians with colleagues and patients. Cell phone technology is affordable for almost everyone, and basic models include digital photography. We present a case series exhibiting the utility of digital pictures taken with patients' cell phones. Our patients had wound infections requiring daily intravenous antibiotics and dressing changes. In years past, these patients would have required prolonged hospitalizations. In the era of managed care, patients with these infections are discharged from the hospital, but close outpatient observation is required to monitor the wound. Our patients lived up to 8 hours away from the hospital. Daily appointments for wound checks in the clinic were not practical. Wounds were thus monitored via cell phone images without the inconvenience of travel and the expense of staying in a local hotel, along with leaving appointments in the clinic available for others with new neurosurgical issues. Wound evaluations were conducted with the cameras on patients' cell phones. These images were transmitted to the surgeon via text messaging and emails. This application of cell phone technology has been documented previously in the literature of other specialties and could attain greater stature as a legitimate method for close outpatient observation by neurosurgeons if medicolegal issues are addressed.

    Full Text Available Abstract Background In their current laboratory-based form, existing vibrotactile sensory augmentation technologies that provide cues of body motion are impractical for home-based rehabilitation use due to their size, weight, complexity, calibration procedures, cost, and fragility. Methods We have designed and developed a cell phone based vibrotactile feedback system for potential use in balance rehabilitation training in clinical and home environments. It comprises an iPhone with an embedded tri-axial linear accelerometer, custom software to estimate body tilt, a "tactor bud" accessory that plugs into the headphone jack to provide vibrotactile cues of body tilt, and a battery. Five young healthy subjects (24 ± 2.8 yrs, 3 females and 2 males and four subjects with vestibular deficits (42.25 ± 13.5 yrs, 2 females and 2 males participated in a proof-of-concept study to evaluate the effectiveness of the system. Healthy subjects used the system with eyes closed during Romberg, semi-tandem Romberg, and tandem Romberg stances. Subjects with vestibular deficits used the system with both eyes-open and eyes-closed conditions during semi-tandem Romberg stance. Vibrotactile feedback was provided when the subject exceeded either an anterior-posterior (A/P or a medial-lateral (M/L body tilt threshold. Subjects were instructed to move away from the vibration. Results The system was capable of providing real-time vibrotactile cues that informed corrective postural responses. When feedback was available, both healthy subjects and those with vestibular deficits significantly reduced their A/P or M/L RMS sway (depending on the direction of feedback, had significantly smaller elliptical area fits to their sway trajectory, spent a significantly greater mean percentage time within the no feedback zone, and showed a significantly greater A/P or M/L mean power frequency. Conclusion The results suggest that the real-time feedback provided by this system can be used

    To determine the bacterial contamination rate of the parent's cell phone and the effectiveness of anti-microbial gel in reducing transmission of bacteria from cell phone to hands. Cross-sectional study of cultures from the cell phone and hands before and after applying anti-microbial gel (n=50). All cell phones demonstrated bacterial contamination. Ninety percent had the same bacteria on the cell phone and their cleaned hands. Twenty two percent had no growth on their hands after applying anti-microbial gel after they had the same bacteria on the cell phone and hands. Ninety-two percent of parents were aware that cell phones carried bacteria, but only 38% cleaned their cell phones at least weekly. Bacterial contamination of cell phones may serve as vectors for nosocomial infection in the neonatal intensive care unit. Bacteria transmitted from cell phone to hands may not be eliminated using anti-microbial gel. Development of hand hygiene and cell phone cleaning guidelines are needed regarding bedside cell phone use.

  20. The relationship between cell phone use, physical and sedentary activity, and cardiorespiratory fitness in a sample of U.S. college students

    Science.gov (United States)

    2013-01-01

    Background Today’s cell phones increase opportunities for activities traditionally defined as sedentary behaviors (e.g., surfing the internet, playing video games). People who participate in large amounts of sedentary behaviors, relative to those who do not, tend to be less physically active, less physically fit, and at greater risk for health problems. However, cell phone use does not have to be a sedentary behavior as these devices are portable. It can occur while standing or during mild-to-moderate intensity physical activity. Thus, the relationship between cell phone use, physical and sedentary activity, and physical fitness is unclear. The purpose of this study was to investigate these relationships among a sample of healthy college students. Methods Participants were first interviewed about their physical activity behavior and cell phone use. Then body composition was assessed and the validated self-efficacy survey for exercise behaviors completed. This was followed by a progressive exercise test on a treadmill to exhaustion. Peak oxygen consumption (VO2 peak) during exercise was used to measure cardiorespiratory fitness. Hierarchical regression was used to assess the relationship between cell phone use and cardiorespiratory fitness after controlling for sex, self-efficacy, and percent body fat. Interview data was transcribed, coded, and Chi-square analysis was used to compare the responses of low and high frequency cell phone users. Results Cell phone use was significantly (p = 0.047) and negatively (β = −0.25) related to cardio respiratory fitness independent of sex, self-efficacy, and percent fat which were also significant predictors (p < 0.05). Interview data offered several possible explanations for this relationship. First, high frequency users were more likely than low frequency users to report forgoing opportunities for physical activity in order to use their cell phones for sedentary behaviors. Second, low frequency users were more

    Capture of surveillance data on mobile devices and rapid transfer of such data from these devices into an electronic database or data management and decision support systems promote timely data analyses and public health response during disease outbreaks. Mobile data capture is used increasingly for malaria surveillance and holds great promise for surveillance of other neglected tropical diseases. We focused on mosquito-borne dengue, with the primary aims of: 1) developing and field-testing a cell phone-based system (called Chaak) for capture of data relating to the surveillance of the mosquito immature stages, and 2) assessing, in the dengue endemic setting of Mérida, México, the cost-effectiveness of this new technology versus paper-based data collection. Chaak includes a desktop component, where a manager selects premises to be surveyed for mosquito immatures, and a cell phone component, where the surveyor receives the assigned tasks and captures the data. Data collected on the cell phone can be transferred to a central database through different modes of transmission, including near-real time where data are transferred immediately (e.g., over the Internet) or by first storing data on the cell phone for future transmission. Spatial data are handled in a novel, semantically driven, geographic information system. Compared with a pen-and-paper-based method, use of Chaak improved the accuracy and increased the speed of data transcription into an electronic database. The cost-effectiveness of using the Chaak system will depend largely on the up-front cost of purchasing cell phones and the recurring cost of data transfer over a cellular network. PMID:23926788

    Secondary task engagement such as cell phone use while driving is a common behavior among adolescents and emerging adults. Texting and other distracting cell phone use in this population contributes to the high rate of fatal car crashes. Peer engagement in similar risky driving behaviors, such as texting, could socially influence driver phone use behavior. The present study investigates the prospective association between peer and emerging adult texting while driving the first year after high school. Surveys were conducted with a national sample of emerging adults and their nominated peers. Binomial logistic regression analyses, adjusting for gender, race/ethnicity, parental education, and family affluence, showed that participants (n=212) with peers (n=675) who reported frequently texting while driving, were significantly more likely to text while driving the following year (odds ratio, 3.01; 95% CI, 1.19-7.59; P=0.05). The findings are consistent with the idea that peer texting behavior influences the prevalence of texting while driving among emerging adults. Copyright © 2017 Elsevier Ltd. All rights reserved.

    As part of a breastfeeding promotion intervention trial in Nigeria, we provided one cell phone per group of 5-7 microcredit clients and instructed the group's cell phone recipient to share weekly breastfeeding voice and text messages with group members. We measured the feasibility and acceptability of using group cell phones by conducting semi-structured exit interviews with 195 microcredit clients whose babies were born during the intervention (target group), in-depth interviews with eight phone recipients and nine non-phone recipients, and 16 focus group discussions with other microcredit clients. Women in the target group said the group phone worked well or very well (64%). They were motivated to try the recommended practices because they trusted the information (58%) and had support from others (35%). Approximately 44% of target women reported that their groups met and shared messages at least once a week. Women in groups that met at least weekly had higher odds of exclusive breastfeeding up to 6 months (OR 5.6, 95% CI 1.6, 19.7) than women in groups that never met. In-depth interviews and focus group discussions indicated that non-phone recipients had positive feelings towards phone recipients, the group phone met participants' needs, and messages were often shared outside the group. In conclusion, group cell phone messaging to promote breastfeeding among microcredit clients is feasible and acceptable and can be part of an effective behaviour change package. © 2016 John Wiley & Sons Ltd.

    Physical activity promotes health and longevity. Further elaboration of the role of physical activity for human health in epidemiological studies on large samples requires accurate methods that are easy to use, cheap, and possible to repeat. The use of telecommunication technologies such as cell phones is highly interesting in this respect. In an earlier report, we showed that physical activity level (PAL) assessed using a cell phone procedure agreed well with corresponding estimates obtained using the doubly labeled water method. However, our earlier study indicated high within-subject variation in relation to between-subject variations in PAL using cell phones, but we could not assess if this was a true variation of PAL or an artifact of the cell phone technique. Our objective was to compare within- and between-subject variations in PAL by means of cell phones with corresponding estimates using an accelerometer. In addition, we compared the agreement of daily PAL values obtained using the cell phone questionnaire with corresponding data obtained using an accelerometer. PAL was measured both with the cell phone questionnaire and with a triaxial accelerometer daily during a 2-week study period in 21 healthy Swedish women (20 to 45 years of age and BMI from 17.7 kg/m² to 33.6 kg/m²). The results were evaluated by fitting linear mixed effect models and descriptive statistics and graphs. With the accelerometer, 57% (95% confidence interval [CI] 40%-66%) of the variation was within subjects, while with the cell phone, within-subject variation was 76% (95% CI 59%-83%). The day-to-day variations in PAL observed using the cell phone questions agreed well with the corresponding accelerometer results. Both the cell phone questionnaire and the accelerometer showed high within-subject variations. Furthermore, day-to-day variations in PAL within subjects assessed using the cell phone agreed well with corresponding accelerometer values. Consequently, our cell phone

    2011-07-15

    Scientists, educators and the general public often need to know times of divergence between species. But they rarely can locate that information because it is buried in the scientific literature, usually in a format that is inaccessible to text search engines. We have developed a public knowledgebase that enables data-driven access to the collection of peer-reviewed publications in molecular evolution and phylogenetics that have reported estimates of time of divergence between species. Users can query the TimeTree resource by providing two names of organisms (common or scientific) that can correspond to species or groups of species. The current TimeTree web resource (TimeTree2) contains timetrees reported from molecular clock analyses in 910 published studies and 17 341 species that span the diversity of life. TimeTree2 interprets complex and hierarchical data from these studies for each user query, which can be launched using an iPhone application, in addition to the website. Published time estimates are now readily accessible to the scientific community, K-12 and college educators, and the general public, without requiring knowledge of evolutionary nomenclature. TimeTree2 is accessible from the URL http://www.timetree.org, with an iPhone app available from iTunes (http://itunes.apple.com/us/app/timetree/id372842500?mt=8) and a YouTube tutorial (http://www.youtube.com/watch?v=CxmshZQciwo).

  15. Cell Phone Ownership and Service Plans Among Low-Income Smokers: The Hidden Cost of Quitlines.

    Science.gov (United States)

    Bernstein, Steven L; Rosner, June-Marie; Toll, Benjamin

    2016-08-01

    Quitlines (QLs) are free, effective sources of treatment for tobacco dependence. Although the QL number is toll-free, the use of cell phones as the sole source of telephony may impose an unintended cost, in terms of cell minutes. To quantify the use of cell-only telephony among self-pay or Medicaid smokers, assess their calling plans, and estimate the impact of a typical course of QL counseling. A survey of smokers age at least 18 years visiting an American urban emergency department from April to July, 2013. Seven-hundred seventy-three smokers were surveyed, of whom 563 (72.8%) were low-income, defined as having Medicaid or no insurance. All low-income smokers had at least one phone: 48 (8.5%) reported land-lines only, 159 (28.2%) land-lines and cells, and 356 (63.2%) cells only. Of the cell phone owners, monthly calling plans provided unlimited minutes for 339/515 (65.8%), at most 250 minutes for 124 (24.1%), and more than 250 minutes for 52 (10.0%). Another recent trial found that QL users make a median of 1 call lasting 28 minutes, with the 75th and 90th percentiles of calls and minutes at 3 and 4 calls, and 48 and 73.6 minutes, respectively. Thus, robust use of QL services could consume 11%-29% of a low-income smoker's typical 250 monthly cell minutes. Among low-income smokers, cell phones are often the sole telephone. Robust use of the QL may impose a substantial burden on low-income smokers' calling plans, and therefore deter use of the QL. Exempting calls to QLs from counting against smokers' plans may help promote QL utilization. Low-income individuals have high rates of smoking, and are more likely to own only cell phones, not landlines, for telephone access. Because cell phone calling plans often have limited numbers of monthly minutes, cell-only individuals may have to spend a substantial proportion of their monthly minutes on QL services. This may act as a deterrent to using an otherwise free, effective means of treatment for tobacco dependence

    Full Text Available Abstract Background Vertebral rotation found in structural scoliosis contributes to trunkal asymmetry which is commonly measured with a simple Scoliometer device on a patient's thorax in the forward flexed position. The new generation of mobile 'smartphones' have an integrated accelerometer, making accurate angle measurement possible, which provides a potentially useful clinical tool for assessing rib hump deformity. This study aimed to compare rib hump angle measurements performed using a Smartphone and traditional Scoliometer on a set of plaster torsos representing the range of torsional deformities seen in clinical practice. Methods Nine observers measured the rib hump found on eight plaster torsos moulded from scoliosis patients with both a Scoliometer and an Apple iPhone on separate occasions. Each observer repeated the measurements at least a week after the original measurements, and were blinded to previous results. Intra-observer reliability and inter-observer reliability were analysed using the method of Bland and Altman and 95% confidence intervals were calculated. The Intra-Class Correlation Coefficients (ICC were calculated for repeated measurements of each of the eight plaster torso moulds by the nine observers. Results Mean absolute difference between pairs of iPhone/Scoliometer measurements was 2.1 degrees, with a small (1 degrees bias toward higher rib hump angles with the iPhone. 95% confidence intervals for intra-observer variability were +/- 1.8 degrees (Scoliometer and +/- 3.2 degrees (iPhone. 95% confidence intervals for inter-observer variability were +/- 4.9 degrees (iPhone and +/- 3.8 degrees (Scoliometer. The measurement errors and confidence intervals found were similar to or better than the range of previously published thoracic rib hump measurement studies. Conclusions The iPhone is a clinically equivalent rib hump measurement tool to the Scoliometer in spinal deformity patients. The novel use of plaster torsos as rib

    In the past, we have repeatedly elaborated on the computer security risk of using smartphones. Today, something new for the paranoid: did you know your smart phone can be used to spy on your PC’s keyboard?!    In fact, the tiny accelerometer, gyroscope and orientation sensors that your smartphone uses to determine its tilt and movements can also determine the letters you type on your computer. Thus, it acts as a hardware “key-logger”! It only requires your smartphone to be put close to your computer keyboard and to run a corresponding, malicious app. The rest is done by the highly precise sensors which can record keyboard vibrations and subsequently the letters you type. In a dedicated study, students of the Georgia Tech College of Computing were able to decipher complete sentences with up to 80 percent accuracy using an iPhone*. In a nice twist, the same feature can also be used to “to infer the occurrence of tap events on the touchscreen as w...

  4. NMR imaging of cell phone radiation absorption in brain tissue

    Gultekin, David H.; Moeller, Lothar

    2013-01-01

    A method is described for measuring absorbed electromagnetic energy radiated from cell phone antennae into ex vivo brain tissue. NMR images the 3D thermal dynamics inside ex vivo bovine brain tissue and equivalent gel under exposure to power and irradiation time-varying radio frequency (RF) fields. The absorbed RF energy in brain tissue converts into Joule heat and affects the nuclear magnetic shielding and the Larmor precession. The resultant temperature increase is measured by the resonance frequency shift of hydrogen protons in brain tissue. This proposed application of NMR thermometry offers sufficient spatial and temporal resolution to characterize the hot spots from absorbed cell phone radiation in aqueous media and biological tissues. Specific absorption rate measurements averaged over 1 mg and 10 s in the brain tissue cover the total absorption volume. Reference measurements with fiber optic temperature sensors confirm the accuracy of the NMR thermometry. PMID:23248293

    2015-09-01

    Most underdeveloped countries do not meet core disease outbreak surveillance because of the lack of human resources, laboratory and infrastructural facilities. The use of cell phone technology for disease outbreak syndromic surveillance is a new phenomenon in Sierra Leone despite its successes in other developing countries like Sri Lanka. In this study we set to evaluate the effectiveness of using cell phone technology for Ebola hemorrhagic fever syndromic surveillance in a high risked community in Sierra Leone. This study evaluated the effectiveness of using cell phone messaging (text and calls) for community Ebola hemorrhagic fever syndromic surveillance in high risked community in southern Sierra Leone. All cell phone syndromic surveillance data used for this study was reported as cell phone alert messages-texts and voice calls; by the Moyamba District Health Management Team for both Ebola hemorrhagic fever suspect and mortalities. We conducted a longitudinal data analysis of the monthly cumulative confirmed Ebola hemorrhagic fever cases and mortalities collected by both the traditional sentinel and community cell phone syndromic surveillance from August 2014 to October 2014. A total of 129 and 49 Ebola hemorrhagic fever suspect and confirmed cases respectively were recorded using the community Ebola syndromic surveillance cell phone alert system by the Moyamba District Health Management Team in October 2014. The average number of Ebola hemorrhagic fever suspects and confirmed cases for October 2014 were 4.16 (Std.dev 3.76) and 1.58 (Std.dev 1.43) respectively. Thirty-four percent (n=76) of the community Ebola syndromic surveillance cell phone alerts that were followed-up within 24 hours reported Ebola hemorrhagic fever suspect cases while 65.92% (n=147) reported mortality. Our study suggests some form of underreporting by the traditional sentinel Ebola hemorrhagic fever disease surveillance system in Moyamba District southern Sierra Leone for August

  7. Predictors of Cell Phone Use in Distracted Driving: Extending the Theory of Planned Behavior.

    2017-09-01

    This study examines the predictors of six distracted driving behaviors, and the survey data partially support Ajzen's (1991) Theory of Planned Behavior (TPB). The data suggest that the attitude variable predicted intention to engage in all six distracted driving behaviors (reading and sending text messages, making and answering cell phone calls, reading/viewing social media, and posting on social media while driving). Extending the model to include past experience and the variable perceived safety of technology yielded an improvement in the prediction of the distraction variables. Specifically, past experience predicted all six distracted driving behaviors, and the variable perceived safety of technology predicted intentions to read/view social media and intention to post on social media while driving. The study provides evidence for the importance of incorporating expanded variables into the original TPB model to predict cell phone use behaviors while driving, and it suggests that it is essential to tailor campaign materials for each specific cell phone use behavior to reduce distracted driving.

  8. Quantitative imaging with a mobile phone microscope.

    Directory of Open Access Journals (Sweden)

    Arunan Skandarajah

    Full Text Available Use of optical imaging for medical and scientific applications requires accurate quantification of features such as object size, color, and brightness. High pixel density cameras available on modern mobile phones have made photography simple and convenient for consumer applications; however, the camera hardware and software that enables this simplicity can present a barrier to accurate quantification of image data. This issue is exacerbated by automated settings, proprietary image processing algorithms, rapid phone evolution, and the diversity of manufacturers. If mobile phone cameras are to live up to their potential to increase access to healthcare in low-resource settings, limitations of mobile phone-based imaging must be fully understood and addressed with procedures that minimize their effects on image quantification. Here we focus on microscopic optical imaging using a custom mobile phone microscope that is compatible with phones from multiple manufacturers. We demonstrate that quantitative microscopy with micron-scale spatial resolution can be carried out with multiple phones and that image linearity, distortion, and color can be corrected as needed. Using all versions of the iPhone and a selection of Android phones released between 2007 and 2012, we show that phones with greater than 5 MP are capable of nearly diffraction-limited resolution over a broad range of magnifications, including those relevant for single cell imaging. We find that automatic focus, exposure, and color gain standard on mobile phones can degrade image resolution and reduce accuracy of color capture if uncorrected, and we devise procedures to avoid these barriers to quantitative imaging. By accommodating the differences between mobile phone cameras and the scientific cameras, mobile phone microscopes can be reliably used to increase access to quantitative imaging for a variety of medical and scientific applications.

    Accurate air temperature observations are important for urban meteorology, for example to study the urban heat island and adverse effects of high temperatures on human health. The number of available temperature observations is often relatively limited. A new development is presented to derive temperature information for the urban canopy from an alternative source: cell phones. Battery temperature data were collected by users of an Android application for cell phones (opensignal.com). The application automatically sends battery temperature data to a server for storage. In this study, battery temperatures are averaged in space and time to obtain daily averaged battery temperatures for each city separately. A regression model, which can be related to a physical model, is employed to retrieve daily air temperatures from battery temperatures. The model is calibrated with observed air temperatures from a meteorological station of an airport located in or near the city. Time series of air temperatures are obtained for each city for a period of several months, where 50% of the data is for independent verification. Results are presented for Buenos Aires, London, Los Angeles, Paris, Mexico City, Moscow, Rome, and Sao Paulo. The evolution of the retrieved air temperatures often correspond well with the observed ones. The mean absolute error of daily air temperatures is less than 2 degrees Celsius, and the bias is within 1 degree Celsius. This shows that monitoring air temperatures employing an Android application holds great promise. Since 75% of the world's population has a cell phone, 20% of the land surface of the earth has cellular telephone coverage, and 500 million devices use the Android operating system, there is a huge potential for measuring air temperatures employing cell phones. This could eventually lead to real-time world-wide temperature maps.

    Ovarian cancer is a leading cause of death from gynecologic cancers in the USA, and early diagnosis can potentially increase 5-year survival rate. Detection of biomarkers derived from hyperplasia of epithelial tissue by enzyme-linked immunosorbent assay (ELISA) proves to be a practical way of early diagnosis of ovarian cancer. However, ELISA is commonly performed in a laboratory setting, and it cannot be used in a clinical setting for on-site consultation. We have shown a microchip ELISA that detects HE4, an ovarian cancer biomarker, from urine using a cell phone integrated with a mobile application for imaging and data analysis. In microchip ELISA, HE4 from urine was first absorbed on the surface; the primary and secondary antibodies were subsequently anchored on the surface via immuno-reaction; and addition of substrate led to color development because of enzymatic labeling. The microchip after color development was imaged using a cell phone, and the color intensity was analyzed by an integrated mobile application. By comparing with an ELISA standard curve, the concentration of HE4 was reported on the cell phone screen. The presented microchip ELISA coupled with a cell phone is portable as opposed to traditional ELISA, and this method can facilitate the detection of ovarian cancer at the point-of-care (POC).

    2017-06-01

    Full Text Available Mobile phones not only increase our availability for communication anytime, anywhere, but also interrupt us anytime, anywhere. This paper empirically examines the role of local context (e.g. activity/location where one receives the call vs. the relational context (e.g. what the phone call is about and from whom in how people make decisions to answer or ignore phone call. Using both quantitative (N=101 and qualitative (N=10 methods, we gathered data on people's cellphone handling practices. Analysis of the data reveals that 1 people are influenced by the availability or unavailability of relational context in making call handling decisions and are rarely influenced by their local context alone; 2 people predict the value of a call to be significantly different before engaging in the call than the value they perceive after the call. Our qualitative data confirmed that the low availability of relational context information not only led to misjudgment of call value but also suboptimal call handling decisions. Together our findings suggest that designing cell phone interfaces that display relational context information can support people in accurately gauging the value of incoming calls to appropriate response decisions in social and professional contexts.

    2018-04-16

    In this article we build on relational Sociometer Theory (Leary, 2005; Leary & Baumeister, 2000) to posit the impact of the belongingness threat of experienced incivility in one's work team on employee feelings of ostracism and subsequent engagement in proactive performance. Integrating the social-relational framework of Self-Identity Orientation Theory (Brewer & Gardner, 1996; Cooper & Thatcher, 2010), we nuance our predictions by hypothesizing that chronic self-identification orientations influence both the effect that experiencing incivility in one's work team exerts on feeling ostracized, and the impact that feeling ostracized has on subsequent employee proactive performance. Using a sample of 212 employees and their 51 supervising managers employed in an Internet service and solution company in China, we found support for our hypothesized model. Implications for theory and practice are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    2016-11-01

    This paper focuses on developing an analysis framework to study the impact of cell phone treatment (cell phone type and call status) on driver behavior in the presence of a dilemma zone. Specifically, we examine how the treatment influences the driver maneuver decision at the intersection (stop or cross) and the eventual success of the maneuver. For a stop maneuver, success is defined as stopping before the stop line. Similarly, for a cross maneuver, success is defined as clearing the intersection safely before the light turns red. The eventual success or failure of the driver's decision process is dependent on the factors that affected the maneuver decision. Hence it is important to recognize the interconnectedness of the stop or cross decision with its eventual success (or failure). Toward this end, we formulate and estimate a joint framework to analyze the stop/cross decision with its eventual success (or failure) simultaneously. The study is conducted based on driving simulator data provided online for the 2014 Transportation Research Board Data Contest at http://depts.washington.edu/hfsm/upload.php. The model is estimated to analyze drivers' behavior at the onset of yellow by employing exogenous variables from three broad categories: driver characteristics, cell phone attributes and driving attributes. We also generate probability surfaces to identify dilemma zone distribution associated with different cell phone treatment types. The plots clearly illustrate the impact of various cellphone treatments on driver dilemma zone behavior. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2014-05-01

    Using a sample of 70 juvenile probationers (39 treatment and 31 controls), we evaluated the effectiveness of a rehabilitation program that combined cognitive-behavioral training and automated phone calls. The cognitive-behavioral training contained six 90-min sessions, one per week, and the phone calls occurred twice per day for the year following treatment. Recidivism was measured by whether they were rearrested and the total number of rearrests during the 1st year. To test the impact of the phone calls, those who received phone calls were divided into high and low groups depending on whether they answered more or less than half of their phone calls. Those who completed the class and answered at least half of their phone calls were less likely to have been arrested and had fewer total arrests.

    To estimate the association between problematic cell phone use and reasoning ability in adolescent. In a stratified cluster sampling design, problematic cell phone use and reasoning ability were evaluated in 929 college students from three universities for twice in one year's follow-up investigation from June 2014 to May 2015. The cross-sectional analysis showed that the score of problematic cell phone use was significantly associated with the score of reasoning ability( the baseline β =-0. 101, 95% CI-0. 168--0. 034; the follow-up in one year's β =-0. 161, 95% CI-0. 255--0. 067). However, the score of problematic cell phone use on the baseline was not associated with the score of reasoning ability in one year late. Interestingly, after controlling of multiple confounding factors and the score of problematic cell phone use on the baseline, the scores of reasoning ability in one year late decreased 0. 40 points( 95%CI-0. 60--0. 20), by the score of problematic cell phone use in one year lateincreased ten percent compared to that on the baseline. Higher problematic cell phone use is significantly associated with poorer reasoning ability in college students.

    Full Text Available Smoking cessation among adolescents is a salient public health issue, as it can preventthe adoption of risky health behaviors and reduce negative impacts on health. Self-efficacy,household and social support systems, and perceived benefits are some important cessationdeterminants. With the popular use of the Internet and cell phone usage among adolescents,smoking cessation programs are beginning to adopt these new delivery methods. The purpose ofthe study is to review interventions between 2005 and 2009 that used the Internet or cell phonesfor smoking cessation among 11 to 19 year olds. A systematic search of the CINAHL, ERIC,Google Scholar, and Medline databases was done. A total of 10 articles met the inclusion criteria.Interventions mainly used the Internet as a form of assistance to enhance the effectiveness of theprogram. One intervention used text messaging through cell phones. Self-efficacy, household andsocial support systems and perceived benefits were found to be significant predictors. Programswith multiple approaches, using the Internet as an adjunct were more effective than programs thatsolely relied on the Internet. Future research is needed to verify its success in cessation practices.Recommendations for future research are provided.

  8. The moderating role of psychological capital in the relationship between job stress and the outcomes of incivility and job involvement amongst call centre employees

    Directory of Open Access Journals (Sweden)

    Sarah B. Setar

    2015-12-01

    Full Text Available Orientation: South African call centres were found to rank amongst those with the highest degree of performance monitoring and feedback. This revelation comes at a time when many scholars concur that research has not entirely succeeded in helping organisations overcome the negative aspects of work and enhance the positive aspects of work, such as job involvement. Research purpose: This study sought to examine the relationship between job stress, job involvement and the display of uncivil behaviour amongst call centre employees, whilst also studying the role of psychological capital (PsyCap in this relationship. Motivation for the study: The study was prompted by the scarcity of research in the area of PsyCap and job involvement, none of which has examined relationships between job stress and the outcomes of incivility and job involvement and the moderating role of PsyCap in this relationship, focusing on call centre employees. Research design, approach and method: A quantitative design employed a cross-sectional survey to collect data from 104 South African call centre employees using a biographical data sheet, the PsyCap Questionnaire, Job Stress Scale, Uncivil Workplace Behaviour Scale and the Job Involvement Scale. Main findings: PsyCap and uncivil workplace behaviour were negatively related, whilst PsyCap and job involvement were positively related. Job stress held predictive value for incivility and the hostility subscale. Hierarchical regression analysis indicated that PsyCap did not moderate the relationship between job stress and incivility and neither did it moderate the relationship between job stress and job involvement. Practical implications: Organisations should work on minimising stressors within the workplace in order to enhance the PsyCap of employees, which not only lowers the risk of incivility displayed by employees but also ensures greater employee involvement. Contribution/value-add: Although previous studies have examined

    Silveira, Geraldo T R; Chang, Shoou-Yuh

    2010-11-01

    This paper presents an overview of cell phone recycling programs currently available in the United States. At the same time, it also provides analyses of the current recycling situation and possible recycling alternatives for Brazil. Although there are several recycling options in the United States, collection rates are still only 10% of all potential devices because customers are not aware of these possibilities. The whole system is financially based on reselling refurbished cell phones and recycled materials to developing countries which represent an effective and strong market. Several recyclers offer funds to collection partners who are either charities or who work with charities while obtaining the materials that they need in order to run their operations. A mobile phone recycling system for Brazil considering the United States experience and the Extended Producer Responsibility (EPR) principle is suggested. A deposit/refund/advance-recycling fee is proposed which might be implemented as a voluntary industrial initiative managed by PRO Brazil, a producer responsibility organization. One widespread public-private agreement will integrate all mobile phone stakeholders, and environmental education actions and promotional events will promote citizen's participation.

    If there is one thing that teenagers like to talk about when it comes to the law, it's who does and does not have the right to search their "stuff." And in the world of "stuff," there is nothing more important to average American teenagers than their cell phones. So when, in the waning days of its 2013-2014 term, the U.S.…

    Texting is associated with adverse health effects including musculoskeletal disorders, sleep disturbances, and traffic crashes. Many studies have relied on self-reported texting frequency, yet the validity of self-reports is unknown. Our objective was to provide some of the first data on the validity of self-reported texting frequency, cell phone characteristics including input device (e.g. touchscreen), key configuration (e.g., QWERTY), and texting styles including phone orientation (e.g., horizontal) and hands holding the phone while texting. Data were collected using a self-administered questionnaire and observation of a texting task among college students ages 18 to 24. To gauge agreement between self-reported and phone bill-derived categorical number of daily text messages sent, we calculated percent of agreement, Spearman correlation coefficient, and a linear weighted kappa statistic. For agreement between self-reported and observed cell phone characteristics and texting styles we calculated percentages of agreement. We used chi-square tests to detect significant differences (α = 0.05) by gender and study protocol. There were 106 participants; 87 of which had complete data for texting frequency analyses. Among these 87, there was 26% (95% CI: 21-31) agreement between self-reported and phone bill-derived number of daily text messages sent with a Spearman's rho of 0.48 and a weighted kappa of 0.17 (95% CI: 0.06-0.27). Among those who did not accurately report the number of daily texts sent, 81% overestimated this number. Among the full sample (n = 106), there was high agreement between self-reported and observed texting input device (96%, 95% CI: 91-99), key configuration (89%, 95% CI: 81-94), and phone orientation while texting (93%, 95% CI: 86-97). No differences were found by gender or study protocol among any items. While young adults correctly reported their cell phone's characteristics and phone orientation while texting, most incorrectly

  16. Cellular phone use while driving at night.

    Use of a cellular phone has been shown to negatively affect one's attention to the driving task, leading to an increase in crash risk. At any given daylight hour, about 6% of US drivers are actively talking on a hand-held cell phone. However, previous surveys have focused only on cell phone use during the day. Driving at night has been shown to be a riskier activity than driving during the day. The purpose of the current study was to assess the rate of hand-held cellular phone use while driving at night, using specialized night vision equipment. In 2006, two statewide direct observation survey waves of nighttime cellular phone use were conducted in Indiana utilizing specialized night vision equipment. Combined results of driver hand-held cellular phone use from both waves are presented in this manuscript. The rates of nighttime cell phone use were similar to results found in previous daytime studies. The overall rate of nighttime hand-held cellular phone use was 5.8 +/- 0.6%. Cellular phone use was highest for females and for younger drivers. In fact, the highest rate observed during the study (of 11.9%) was for 16-to 29-year-old females. The high level of cellular phone use found within the young age group, coupled with the increased crash risk associated with cellular phone use, nighttime driving, and for young drivers in general, suggests that this issue may become an important transportation-related concern.

  17. Mobile Phone Radiation: Physiological & Pathophysiologcal Considerations.

    It is documented that electromagnetic emissions from mobile phones can interfere with brain's signal processing activity due to their oscillatory similitude to the inherent rhythms of the brain, akin to "electromagnetic interference" observed while using mobile phones in aeroplanes. At high power density levels, thermal effects occur, some of which can be attributed to heat induced stress mechanisms. The less understood non-thermal effects occur at low radio frequency/microwave power density levels and are not accompanied by any body temperature rise. The safety standards set by international agencies are based on thermal effects. For the mobile phones, ICNIRP 1998 guidelines restrict spatial peak of microwave exposure to 2 W/Kg SAR values averaged over 10 g of tissue for 6 minutes. Some of the reported electromagnetic radiation (EMR) induced adverse effects are brain tumours, male infertility and immune dysfunction with increased susceptibility to infections. Pathophysiological mechanisms of interaction of EMR at plasma membrane are calcium efflux from cell membranes, increased expression of stress proteins, influence on channels/gap junctions in cell membrane, overproduction of reactive oxygen species, ornithine decarboxylase activation, reduction in melatonin levels, decrease in protein kinase C activity, damage to DNA and change in gene expression in brain cells and altered blood-brain barrier. There are equal number of conflicting reports in literature regarding EMR exposure and brain tumours. A comprehensive review concludes "overall the studies published to date do not demonstrate an increased risk within approximately 10 years of use for any tumour of the brain or any other head tumour." Another review summarises that there is "enough data to convince that long-term exposure to low intensity EMR below the ICNIRP guidelines can promote cancer development". However the time limit for exposure has been suggested as more than 10 years. For conducting

    The issue of whether cell phone usage can contribute toward the development of brain tumors has recently been reignited with the International Agency for Research on Cancer classifying radiofrequency electromagnetic fields as 'possibly' carcinogenic to humans in a WHO report. To our knowledge, this is the largest study reporting on the incidence and mortality of malignant brain tumors after long-term use of the cell phone by more than 23 million users. A population-based study was carried out the numbers of cell phone users were collected from the official statistics provided by the National Communication Commission. According to National Cancer Registry, there were 4 incidences and 4 deaths due to malignant neoplasms in Taiwan during the period 2000-2009. The 10 years of observational data show that the intensive user rate of cell phones has had no significant effect on the incidence rate or on the mortality of malignant brain tumors in Taiwan. In conclusion, we do not detect any correlation between the morbidity/mortality of malignant brain tumors and cell phone use in Taiwan. We thus urge international agencies to publish only confirmatory reports with more applicable conclusions in public. This will help spare the public from unnecessary worries.
