    Bautista, John Robert; Lin, Trisha T C

    2017-10-01

    To explore how and why mobile instant messaging applications are used by Filipino nurses as part of their work. Guided by the uses and gratifications theory, in-depth interviews with 20 staff nurses working in 9 hospitals (ie, 4 private and 5 public hospitals) in the Philippines were conducted in July 2015. Interview data were analysed through a phenomenological perspective to thematic analysis. Results show that mobile instant messaging applications such as Facebook Messenger and Viber were mostly used by staff nurses and these were accessed using their own smartphones. Thematic analysis indicates that they were used to meet staff nurses' need for information exchange, socialization, and catharsis. Moreover, user interactions vary depending on members within a chat group. For instance, communication via mobile instant messaging applications are much formal when superiors are included in a chat group. In general, the results show that mobile instant messaging applications are routinely used by Filipino staff nurses not only for clinical purposes (ie, information exchange) but also for non-clinical purposes (ie, socialization and catharsis). This paper ends with several practical and theoretical implications including future research directions. © 2017 John Wiley & Sons Australia, Ltd.

  5. Delaying gratification depends on social trust

    Delaying gratification is hard, yet predictive of important life outcomes, such as academic achievement and physical health. Prominent theories focus on the role of self-control, hypersensitivity to immediate rewards, and the cost of time spent waiting. However, delaying gratification may also require trust in people delivering future rewards as promised. To test the role of social trust, participants were presented with character vignettes and faces that varied in trustworthiness, and then choose between hypothetical smaller immediate or larger delayed rewards from those characters. Across two experiments, participants were less willing to wait for delayed rewards from less trustworthy characters, and perceived trustworthiness predicted willingness to delay gratification. These findings provide the first demonstration of a causal role for social trust in willingness to delay gratification, independent of other relevant factors, such as self-control or reward history. Thus, delaying gratification requires choosing not only a later reward, but a reward that is potentially less likely to be delivered, when there is doubt about the person promising it. Implications of this work include the need to revise prominent theories of delay of gratification, and new directions for interventions with populations characterized by impulsivity. PMID:23801977

Respondents indicated that they watched television to pass time, and, secondarily, for practical purposes (e.g., learning how to be safe.Conclusion – Gratification theory provides a useful framework for library and information professionals to identify how populations define information problems and reliable sources, and their information seeking behaviours and motivations. Chatman’s analysis indicates that the everyday problems faced by the lower working class are not, and will not be, met by traditional sources that information professionals assume to be of value for the population. Based on these research results, Chatman calls on information professionals to critically evaluate and broaden their understanding of how problems are defined and addressed by the specific populations they seek to serve – to consider the relationships between the pressing realities of their service populations and everyday information that addresses those realities. This understanding will enable information professionals to determine if, how, and by what means, they should develop and package information to meet the needs of their service populations and communities.

  19. Escaping the impulse to immediate gratification: the prospect concept promotes a future-oriented mindset, prompting an inclination towards delayed gratification.

    Science.gov (United States)

    Cheng, Ying-Yao; Shein, Paichi Pat; Chiou, Wen-Bin

    2012-02-01

    People's willingness to postpone receiving an immediate reward in order to gain additional benefits in the future, that is, a tendency to shallow delay discounting, is closely related to one's health, wealth, and happiness. We conducted two experiments investigating how the prospect concept can induce a future-oriented mindset and induce people to behave accordingly. We found that engaging in prospective imagery led the participants to focus on delayed utility over immediate utility in financial decisions (Experiment 1). Participants who received the prospect prime via a scrambled-sentence task decreased their desire to pursue hedonic activities for instant gratification (Experiment 2). Moreover, a state of future orientation mediated the effect of the prospect prime on measures of delayed gratification (Experiments 1 and 2). Thus, reminders of prospect may activate a mindset for future orientation by which delayed gratification is strengthened. ©2011 The British Psychological Society.

  20. Automatic updating of times remaining in surgical cases using bayesian analysis of historical case duration data and "instant messaging" updates from anesthesia providers.

    2009-03-01

    Operating room (OR) whiteboards (status displays) communicate times remaining for ongoing cases to perioperative stakeholders (e.g., postanesthesia care unit, anesthesiologists, holding area, and control desks). Usually, scheduled end times are shown for each OR. However, these displays are inaccurate for predicting the time that remains in a case. Once a case scheduled for 2 h has been on-going for 1.5 h, the median time remaining is not 0.5 h but longer, and the amount longer differs among procedures. We derived the conditional Bayesian lower prediction bound of a case's duration, conditional on the minutes of elapsed OR time. Our derivations make use of the posterior predictive distribution of OR times following an exponential of a scaled Student t distribution that depends on the scheduled OR time and several parameters calculated from historical case duration data. The statistical method was implemented using Structured Query Language (SQL) running on the anesthesia information management system (AIMS) database server. In addition, AIMS workstations were sent instant messages displaying a pop-up dialog box asking for anesthesia providers' estimates for remaining times. The dialogs caused negotiated interruptions (i.e., the anesthesia provider could reply immediately, keep the dialog displayed, or defer response). There were no announcements, education, or efforts to promote buy-in. After a case had been in the OR longer than scheduled, the median remaining OR time for the case changes little over time (e.g., 35 min left at 2:30 pm and also at 3:00 pm while the case was still on-going). However, the remaining time differs substantially among surgeons and scheduled procedure(s) (16 min longer [10th percentile], 35 min [50th], and 86 min [90th]). We therefore implemented an automatic method to estimate the times remaining in cases. The system was operational for >119 of each day's 120 5-min intervals.

    With widespread adoption of electronic health records (EHRs) and electronic clinical documentation, health care organizations now have greater faculty to review clinical data and evaluate the efficacy of quality improvement efforts. Unfortunately, I believe there is a fundamental gap between actual health care delivery and what we document in the current EHR systems. This process of capturing the patient encounter, which I'll refer to as transcription, is prone to significant data loss due to inadequate methods of data capture, multiple points of view, and bias and subjectivity in the transcriptional process. Our current EHR, text-based clinical documentation systems are lossy abstractions - one sided accounts of what take place between patients and providers. Our clinical notes contain the breadcrumbs of relationships, conversations, physical exams, and procedures but often lack the ability to capture the form, the emotions, the images, the nonverbal communication, and the actual narrative of interactions between human beings. I believe that a video record, in conjunction with objective transcriptional services and other forms of data capture, may provide a closer approximation to the truth of health care delivery and may be a valuable tool for healthcare improvement.

    Local instant conservation equations for two-phase flow are derived. Derivation of the equation starts from the recording of integral laws of conservation for a fixed reference volume, containing both phases. Transformation of the laws, using the Leibniz rule and Gauss theory permits to obtain the sum of two integrals as to the volume and integral as to the surface. Integrals as to the volume result in local instant differential equations, in particular derivatives for each phase, and integrals as to the surface reflect local instant conditions of a jump on interface surface

  2. Can the attention training technique turn one marshmallow into two? Improving children's ability to delay gratification.

    Science.gov (United States)

    Murray, Joanne; Theakston, Anna; Wells, Adrian

    2016-02-01

    The seminal Marshmallow Test (Mischel & Ebbesen, 1970) has reliably demonstrated that children who can delay gratification are more likely to be emotionally stable and successful later in life. However, this is not good news for those children who can't delay. Therefore, this study aimed to explore whether a metacognitive therapy technique, Attention Training (ATT: Wells, 1990) can improve young children's ability to delay gratification. One hundred children participated. Classes of 5-6 year olds were randomly allocated to either the ATT or a no-intervention condition and were tested pre and post-intervention on ability to delay gratification, verbal inhibition (executive control), and measures of mood. The ATT intervention significantly increased (2.64 times) delay of gratification compared to the no-intervention condition. After controlling for age and months in school, the ATT intervention and verbal inhibition task performance were significant independent predictors of delay of gratification. These results provide evidence that ATT can improve children's self-regulatory abilities with the implication that this might reduce psychological vulnerability later in life. The findings highlight the potential contribution that the Self-Regulatory Executive Function (S-REF) model could make to designing techniques to enhance children's self-regulatory processes.

    This study extends Uses and Gratifications theory by examining the uses and gratifications of a new technological device, the tablet computer, and investigating the differential uses and gratifications of tablet computers across the life-span. First, we utilized a six-week tablet training intervention to adapt and extend existing measures to the tablet as a technological device. Next, we used paper-based and online surveys (N=847), we confirmed four main uses of tablets: 1) Information Seeking, 2) Relationship Maintenance, 3) Style, 4) Amusement and Killing time, and added one additional use category 5) Organization. We discovered differences among the five main uses of tablets across the life-span, with older adults using tablets the least overall. Builders, Boomers, GenX and GenY all reported the highest means for information seeking. Finally, we used a structural equation model to examine how uses and gratifications predicts hours of tablet use. The study provides limitations and suggestions for future research and marketers. In particular, this study offers insight to the relevancy of theory as it applies to particular information and communication technologies and consideration of how different periods in the life-span affect tablet motivations.

    Little has been published on gratification disorder ("infantile masturbation") in early childhood. To expand on the profile of patients diagnosed with this condition. Retrospective case note review; Fraser of Allander Neurosciences Unit paediatric neurology outpatient department 1972-2002. Thirty one patients were diagnosed (11 males and 20 females). Twenty one were referred for evaluation of possible epileptic seizures or epilepsy. The median age at first symptoms was 10.5 months (range 3 months to 5 years 5 months). The median age at diagnosis was 24.5 months (range 5 months to 8 years). The median frequency of events was seven times per week, and the median length 2.5 minutes. Events occurred in any situation in 10 children, and in a car seat in 11. Types of behaviour manifested were dystonic posturing in 19, grunting in 10, rocking in 9, eidetic imagery in 7, and sweating in 6. Two children had been previously diagnosed as having definite epilepsy. In nine cases home video was invaluable in allowing confident diagnosis. Gratification disorder, otherwise called infantile masturbation, is an important consideration in the differential diagnosis of epilepsy and other paroxysmal events in early childhood. Home video recording of events often prevents unnecessary investigations and treatments.

    Full Text Available Objective – To examine provider pessimism by comparing user and provider perception of the same instant messaging reference transaction.Design – Instant messaging users and providers completed post-reference transaction surveys which were analyzed using the pair perception comparison method.Setting – A large research university in the United States.Subjects – Two hundred undergraduate journalism students (users of the instant messaging service and 51 Master of Library Science (MLS students enrolled in a reference services class (providers of the instant messaging service.Methods – The authors created a research help webpage from which users could access the instant messaging service. Prior to service availability, providers received reference instruction and demonstrated reference aptitude through in-class activities. The authors briefed providers on the project and provided a wiki containing resources they might need during reference transactions. Providers worked in two-hour shifts, and two providers were available during each shift. The service was available for one week while potential users completed a journalism assignment. The authors asked both users and providers of the service to complete an online survey at the conclusion of the reference transaction. Users and providers completed different surveys, but both types included the following four elements: questions to aid in matching a user to a provider; questions about satisfaction with the service based on guidelines put forth by the Reference and User Services Association (RUSA; open-ended questions about the reference transaction; and questions regarding demographics, prior reference service usage, and knowledge of instant messaging. There were 55 valid reference transactions, and from those, the authors matched 26 pairs of user and provider surveys.

  17. The Allure of Privacy or the Desire for Self-Expression? Identifying Users' Gratifications for Ephemeral, Photograph-Based Communication.

    Science.gov (United States)

    Waddell, T Franklin

    2016-07-01

    Temporary messaging programs continue to rise in popularity, due in large part to the perceived privacy that they afford. However, recent controversies have revealed that messages shared on ephemeral messaging services are persistent and potentially retrieval, thus undermining the privacy they are assumed to provide. Given this paradox, why are temporary messaging services so popular? Does the allure of privacy still motivate the use of temporary messaging programs? Or, if privacy is no longer afforded by ephemeral messaging, what other psychological gratifications do these applications fulfill that might account for their continued use? Informed by the Modality-Agency-Interactivity-Navigability (MAIN) model and the uses and gratifications tradition, the current study conducted qualitative interviews to identify the gratifications that individuals derive from the popular ephemeral messaging application, Snapchat. Study results show that the visual affordances of ephemeral messaging have legitimized photographic communication, providing self-expression and relational gratifications that are unfulfilled by text-based applications. By comparison, users report low levels of trust in the privacy affordances of ephemeral messaging, and instead projecting negative effects of temporary messaging on other users rather than self. Theoretical and practical implications of these results are discussed.

    2014-01-01

    This study used longitudinal panel survey data collected from 417 adolescents at 2 points in time 1 year apart. It examined relationships between Internet risks changes in Time 2 and social media gratifications-sought, Internet addiction symptoms, and social media use all measured at Time 1. By controlling for age, gender, education, and criterion variable scores in Internet addiction at Time 1, entertainment and instant messaging use at Time 1 significantly predicted increased Internet addiction measured at Time 2. The study also controlled for demographics and scores of criterion variables in Internet risks: targeted for harassment, privacy exposed, and pornographic or violent content consumed in Time 1. Gratifications-sought (including status-gaining, expressing opinions, and identity experimentation), Internet addiction symptoms (including withdrawal and negative life consequences), and social media use (in particular, blogs, and Facebook) significantly predicted Internet risk changes in Time 2. These findings suggest that, with their predictive power, these predictors at Time 1 could be used to identify those adolescents who are likely to develop Internet addiction symptoms and the likelihood of experiencing Internet risks based on their previous gratifications-sought, previous addiction symptoms, and their habits of social media use at Time 1.

The results showed that 8 to 13 percent of iron in the noodles was available for absorption of which contributed to 0.79 mg absorbed iron per day. This amount was too low to meet certain requirements for children, adolescents and menstruating women. With added pork or vegetables, iron availability increased by 2 to 3 times, and by 4 times with added pork and collard or cabbage (p<0.001).

  11. Generalized trust predicts young children's willingness to delay gratification.

    2018-05-01

    Young children's willingness to delay gratification by forgoing an immediate reward to obtain a more desirable one in the future predicts a wide range of positive social, cognitive, and health outcomes. Standard accounts of this phenomenon have focused on individual differences in cognitive control skills that allow children to engage in goal-oriented behavior, but recent findings suggest that person-specific trust is also important, with children showing a stronger tendency to delay gratification if they have reason to trust the individual who is promising the future reward. The current research builds on those findings by examining generalized trust, which refers to the extent to which others are generally viewed as trustworthy. A total of 150 3- to 5-year-olds in China were tested. Participants were given the opportunity to obtain one sticker immediately, or wait for 15 min for two stickers. Results showed that participants with high levels of generalized trust waited longer even after controlling for age and level of executive function. These results suggest that trust plays a role in delaying gratification even when children have no information about the individual who is promising the future reward. More broadly, the findings build on recent evidence that there is more to delay of gratification than cognitive capacity, and they suggest that there are individual differences in whether children consider sacrificing for a future outcome to be worth the risk.

    2017-07-01

    Full Text Available An intelligent tour service system including an augmented reality (AR tour-sharing Application (APP and a query-answering server was developed in this study to promote tourist attractions involving local Hakka culture in Thailand. Subsequently, use of this APP to navigate Hakka culture tourist attractions in Thailand was observed. The novel random neural networks (RNNs were proposed to obtain query-answering services, and the practical experimental results showed that the accuracy of RNNs was 99.51%. This study also integrated the Technology Acceptance Model with Uses and Gratifications Theory to predict the gratification, usage intention, and user attitudes toward marketed attractions of the AR tour-sharing APP. A questionnaire survey was conducted, and 446 valid questionnaires were returned. The following results were obtained: (a self-presentation and perceived usefulness (PU directly influenced gratification; (b perceived entertainment indirectly influenced gratification through perceived ease of use and PU, and information sharing indirectly influenced gratification through PU; and (c gratification was significantly and positively related to usage intention and attitude toward attractions. Based on these results, suggestions that new technology marketing can be used to promote causes other than Hakka tourist attractions established in Thailand can be contrived. For example, the tour-sharing APP developed in this study could be applied to emphasize the characteristics of Thai Hakka culture; users’ fondness for self-presentation and information sharing can be used for word-of-mouth marketing to attract additional visitors. In addition, this research provides a reference for enterprises and marketers regarding the use of AR tour-sharing APPs to market tourist attractions, and also for future related studies.

  6. Instant Gratification: Striking a Balance Between Rich Interactive Visualization and Ease of Use for Casual Web Surfers

    Interactive visualizations can be powerful tools for helping students, teachers, and the general public comprehend significant features in rich datasets and complex systems. Successful use of such visualizations requires viewers to have, or to acquire, adequate expertise in use of the relevant visualization tools. In many cases, the learning curve associated with competent use of such tools is too steep for casual users, such as members of the lay public browsing science outreach web sites or K-12 students and teachers trying to integrate such tools into their learning about geosciences. "Windows to the Universe" (http://www.windows.ucar.edu) is a large (roughly 6,000 web pages), well-established (first posted online in 1995), and popular (over 5 million visitor sessions and 40 million pages viewed per year) science education web site that covers a very broad range of Earth science and space science topics. The primary audience of the site consists of K-12 students and teachers and the general public. We have developed several interactive visualizations for use on the site in conjunction with text and still image reference materials. One major emphasis in the design of these interactives has been to ensure that casual users can quickly learn how to use the interactive features without becoming frustrated and departing before they were able to appreciate the visualizations displayed. We will demonstrate several of these "user-friendly" interactive visualizations and comment on the design philosophy we have employed in developing them.

    Song, Indeok; LaRose, Robert; Eastin, Matthew S; Lin, Carolyn A

    2004-08-01

    Internet addiction has been identified as a pathological behavior, but its symptoms may be found in normal populations, placing it within the scope of conventional theories of media attendance. The present study drew upon fresh conceptualizations of gratifications specific to the Internet to uncover seven gratification factors: Virtual Community, Information Seeking, Aesthetic Experience, Monetary Compensation, Diversion, Personal Status, and Relationship Maintenance. With no parallel in prior research, Virtual Community might be termed a "new" gratification. Virtual Community, Monetary Compensation, Diversion, and Personal Status gratifications accounted for 28% of the variance in Internet Addiction Tendency. The relationship between Internet addiction and gratifications was discussed in terms of the formation of media habits and the distinction between content and process gratifications.

  8. Regret Expression and Social Learning Increases Delay to Sexual Gratification.

    Directory of Open Access Journals (Sweden)

    Amanda J Quisenberry

    Full Text Available Modification and prevention of risky sexual behavior is important to individuals' health and public health policy. This study employed a novel sexual discounting task to elucidate the effects of social learning and regret expression on delay to sexual gratification in a behavioral task.Amazon Mechanical Turk Workers were assigned to hear one of three scenarios about a friend who engages in similar sexual behavior. The scenarios included a positive health consequence, a negative health consequence or a negative health consequence with the expression of regret. After reading one scenario, participants were asked to select from 60 images, those with whom they would have casual sex. Of the selected images, participants chose one image each for the person they most and least want to have sex with and person most and least likely to have a sexually transmitted infection. They then answered questions about engaging in unprotected sex now or waiting some delay for condom-protected sex in each partner condition.Results indicate that the negative health outcome scenario with regret expression resulted in delayed sexual gratification in the most attractive and least STI partner conditions, whereas in the least attractive and most STI partner conditions the negative health outcome with and without regret resulted in delayed sexual gratification.Results suggest that the sexual discounting task is a relevant laboratory measure and the framing of information to include regret expression may be relevant for prevention of risky sexual behavior.

    Instant messaging (IM) is when users communicate instantly via their mobile devices, and it has become one of the most preferred choices of tools to communicate amongst health professions students. The aim of this study was to understand how dental students communicate via IM, faculty members' perspectives on using IM to communicate with students, and whether such tools are useful in the learning environment. After free-associating themes on online communication, two draft topic guides for structured interviews were designed that focussed on mobile device-related communication activities. A total of 20 students and six faculty members at the University of Birmingham School of Dentistry agreed to take part in the interviews. Students were selected from years 1-5 representing each year group. The most preferred communication tools were emails, social networking, and IM. Emails were used for more formal messages, and IM and social networking sites were used for shorter messages. WhatsApp was the most used IM app because of its popular features such as being able to check if recipients have read and received messages and group work. The students reported that changes were necessary to improve their communication with faculty members. The faculty members reported having mixed feelings toward the use of IM to communicate with students. The students wished to make such tools a permanent part of their learning environment, but only with the approval of faculty members. The faculty members were willing to accept IM as a communication tool only if it is monitored and maintained by the university and has a positive effect on learning.

  15. Can Adolescents Learn Self-control? Delay of Gratification in the Development of Control over Risk Taking

    Science.gov (United States)

    Duckworth, Angela L.; Sznitman, Sharon; Park, Sunhee

    2010-01-01

    Recent findings from developmental neuroscience suggest that the adolescent brain is too immature to exert control over impulsive drives, such as sensation seeking, that increase during adolescence. Using a discounting of delayed reward paradigm, this research examines the ability to delay gratification as a potential source of control over risk-taking tendencies that increase during adolescence. In addition, it explores the role of experience resulting from risk taking as well as future time perspective as contributors to the development of this ability. In a nationally representative sample (n=900) of young people aged 14–22, a structural equation analysis shows that risk taking as assessed by use of three popular drugs (tobacco, marijuana, and alcohol) is inversely related to the ability to delay gratification. The relation is robust across gender, age, and different levels of sensation seeking. In addition, high sensation seekers exhibit dramatic age-related increase in delay of gratification, lending support to the hypothesis that engaging in risky behavior provides experience that leads to greater patience for long-term rewards. The findings support the conclusion that a complete understanding of the development of self-control must consider individual differences not easily explained by universal trends in brain maturation.

    Science.gov (United States)

    Hedman, Peter; Karras, Tero; Lehtinen, Jaakko

    2017-05-01

    Instant Radiosity and its derivatives are interactive methods for efficiently estimating global (indirect) illumination. They represent the last indirect bounce of illumination before the camera as the composite radiance field emitted by a set of virtual point light sources (VPLs). In complex scenes, current algorithms suffer from a difficult combination of two issues: it remains a challenge to distribute VPLs in a manner that simultaneously gives a high-quality indirect illumination solution for each frame, and to do so in a temporally coherent manner. We address both issues by building, and maintaining over time, an adaptive and temporally coherent distribution of VPLs in locations where they bring indirect light to the image. We introduce a novel heuristic sampling method that strives to only move as few of the VPLs between frames as possible. The result is, to the best of our knowledge, the first interactive global illumination algorithm that works in complex, highly-occluded scenes, suffers little from temporal flickering, supports moving cameras and light sources, and is output-sensitive in the sense that it places VPLs in locations that matter most to the final result.

  5. Rational temporal predictions can underlie apparent failures to delay gratification

    Science.gov (United States)

    McGuire, Joseph T.; Kable, Joseph W.

    2013-01-01

    An important category of seemingly maladaptive decisions involves failure to postpone gratification. A person pursuing a desirable long-run outcome may abandon it in favor of a short-run alternative that has been available all along. Here we present a theoretical framework in which this seemingly irrational behavior emerges from stable preferences and veridical judgments. Our account recognizes that decision makers generally face uncertainty regarding the time at which future outcomes will materialize. When timing is uncertain, the value of persistence depends crucially on the nature of a decision-maker’s prior temporal beliefs. Certain forms of temporal beliefs imply that a delay’s predicted remaining length increases as a function of time already waited. In this type of situation, the rational, utility-maximizing strategy is to persist for a limited amount of time and then give up. We show empirically that people’s explicit predictions of remaining delay lengths indeed increase as a function of elapsed time in several relevant domains, implying that temporal judgments offer a rational basis for limiting persistence. We then develop our framework into a simple working model and show how it accounts for individual differences in a laboratory task (the well-known “marshmallow test”). We conclude that delay-of-gratification failure, generally viewed as a manifestation of limited self-control capacity, can instead arise as an adaptive response to the perceived statistics of one’s environment.

    Zhang, Yin; Tang, Leo Shing-Tung; Leung, Louis

    2011-12-01

    This study explores whether and how gratifications and psychological traits impact people's Facebook use. First, a factor analysis of an online survey (N= 437) outlined a unique set of gratifications obtained from the use of Facebook. Six aspects of gratifications (i.e., social surveillance, entertainment, recognition, emotional support, network extension, and maintenance) were identified. Results from regression analyses showed that psychological traits (i.e., collective self-esteem, online emotional openness, and traitlike communication apprehension) were strong predictors of most Facebook gratifications. Additionally, gratifications and, to a lesser extent, psychological traits significantly predicted Facebook usage, both in perceived importance and different indicators in the level of Facebook use.

    Full Text Available Background: Despite the extensive research on delayed gratification over the past few decades, the neurocognitive processes that subserve delayed gratification remains unclear. As an exploratory step in studying these processes, the present study aims to describe the executive function profiles of children who were successful at delaying gratification and those who were not. =Methods: A total of 138 kindergarten students (65 males, 73 females; Mage = 44 months, SD= 3.5; age range= 37 to 53 months were administered a delayed gratification task, a 1-back test, a Day/night Stroop test and a Go/no-go test. The outcome measures of these tests were then analyzed between groups using a Multivariate Analysis of Variance, and subsequently a Multivariate Analysis of Covariance incorporating age as a covariate.Results: Children who were successful in delaying gratification were significantly older and had significantly better outcomes in the 1-back test and go/no-go test. With the exception of the number of hits in the go/no-go test, all other group differences remained significant after controlling for age.Conclusion:Children who were successful in delaying gratification showed better working memory and motor inhibition relative to those who failed the delayed gratification task. The implications of these findings are discussed

    Background: Despite the extensive research on delayed gratification over the past few decades, the neurocognitive processes that subserve delayed gratification remains unclear. As an exploratory step in studying these processes, the present study aims to describe the executive function profiles of children who were successful at delaying gratification and those who were not. Methods: A total of 138 kindergarten students (65 males, 73 females; Mage = 44 months, SD = 3.5; age range = 37–53 months) were administered a delayed gratification task, a 1-back test, a Day/night Stroop test and a Go/no-go test. The outcome measures of these tests were then analyzed between groups using a Multivariate Analysis of Variance, and subsequently a Multivariate Analysis of Covariance incorporating age as a covariate. Results: Children who were successful in delaying gratification were significantly older and had significantly better outcomes in the 1-back test and go/no-go test. With the exception of the number of hits in the go/no-go test, all other group differences remained significant after controlling for age. Conclusion: Children who were successful in delaying gratification showed better working memory and motor inhibition relative to those who failed the delayed gratification task. The implications of these findings are discussed. PMID:27493638

    Problematic Internet use has long been a matter of concern; however, few studies extend this line of research from general Internet use to the use of social network sites (SNSs), or explicate the problematic use of SNSs by understanding what factors may enhance or reduce users' compulsive behaviors and excessive form of use on SNSs. Building on literature that found a positive relationship between gratifications sought from the Internet and problematic Internet use, this study first explores the types of gratifications sought from SNSs and examines their relationship with problematic SNS use. It found that three types of gratifications-diversion, self-presentation, and relationship building-were positively related to problematic SNS use. In addition, with a growing body of research on SNS privacy, a moderating role of privacy concerns on SNSs has been proposed to understand how it can influence the relationship between gratifications sought from SNSs and problematic SNS use. The findings suggest that different subdimensions of privacy concerns interact with gratifications sought in different manners. In other words, privacy concerns, including unauthorized secondary use and improper access, play a more influential role in constraining the positive relationship between gratifications sought and problematic SNS use when individuals seek to build relationships on SNSs. However, if individuals seek to have diversion on SNSs, their privacy concerns will be overridden by their gratifications sought, which in turn leads to problematic SNS use. Implications of these findings for future research are discussed.

    This study examined the associations between academic delay of gratification, self-efficacy beliefs, and time management among academically unprepared college students participating in a summer-immersion program. This study also examined whether the relation of self-efficacy with time management is mediated by academic delay of gratification. Analysis indicated that self-efficacy was directly associated with time management, as delay of gratification served to mediate this effect partially. Self-efficacy emerged as the strongest positive predictor of academic achievement.

  12. Rate Aware Instantly Decodable Network Codes

    2016-02-26

    This paper addresses the problem of reducing the delivery time of data messages to cellular users using instantly decodable network coding (IDNC) with physical-layer rate awareness. While most of the existing literature on IDNC does not consider any physical layer complications, this paper proposes a cross-layer scheme that incorporates the different channel rates of the various users in the decision process of both the transmitted message combinations and the rates with which they are transmitted. The completion time minimization problem in such scenario is first shown to be intractable. The problem is, thus, approximated by reducing, at each transmission, the increase of an anticipated version of the completion time. The paper solves the problem by formulating it as a maximum weight clique problem over a newly designed rate aware IDNC (RA-IDNC) graph. Further, the paper provides a multi-layer solution to improve the completion time approximation. Simulation results suggest that the cross-layer design largely outperforms the uncoded transmissions strategies and the classical IDNC scheme. © 2015 IEEE.

    Noodles are one of the staple foods consumed in many Asian countries. Instant noodles have become internationally recognized food, and worldwide consumption is on the rise. The properties of instant noodles like taste, nutrition, convenience, safety, longer shelf-life, and reasonable price have made them popular. Quality factors important for instant noodles are color, flavor, and texture, cooking quality, rehydration rates during final preparation, and the presence or absence of rancid taste after extended storage. Microstructure of dough and noodles has been studied to understand the influence of ingredients and processing variables on the noodle quality by employing scanning electron microscopy. Applications of newer techniques like confocal laser scanning microscopy and epifluorescence light microscopy employed to understand the microstructure changes in dough and noodles have also been discussed. Sincere efforts of researchers are underway to improve the formulation, extend the shelf life, and promote universal fortification of instant noodles. Accordingly, many researchers are exploring the potential of noodle fortification as an effective public health intervention and improve its nutritional properties. This review focuses on the functionality of ingredients, unit operations involved, quality criteria for evaluation, recent trends in fortification, and current knowledge in relation to instant noodles.

    Full Text Available Interpersonal communication should ideally in face to face, until the achievement of intimate communication. Instant messenger makes interpersonal communication easier and more efficient. However, it also resulted in less effective communication to occur, because it only uses text messaging as a means to convey a message so frequent miscommunication. This study wanted to see how the use of instant messenger among teenagers in interpersonal communication. The theory used in this study is a Computer Mediated Communication, Ecology Media and Interpersonal Intimacy. The method used in this research is phenomenology. The results of this study indicate that the instant messenger is a medium that is considered to be practical and easy to communicate interpersonally with family, friends, and lovers. Interpersonal communication process through instant messenger can not reach the stage of intimate relationship, because of interactions that occur frequently experienced miscommunication due to an incorrect perception. Interpersonal communication is more effective if it is done face to face. Teens when communicating via instant messenger, tend not to believe and to tell the truth.

    This study was an exploratory examination of the influence of mothers' teaching behaviors, strategies, and child-rearing attitudes on their children's ability to delay gratification. In an externally imposed delay of gratification situation, 30 mothers from a rural university community taught their children strategies that could help them refrain from touching a brightly wrapped present when the mothers left the room. Results showed that mothers of children who did not delay gratification exhibited teaching behaviors and child-rearing attitudes consistent with a permissive parenting style, whereas mothers of children who did delay gratification exhibited teaching behaviors and child-rearing attitudes consistent with an authoritative parenting style. The results of this study are discussed with respect to the development of children's self-control and self-regulatory abilities.

    Full Text Available We replicate the Stanford marshmallow experiment with a sample of 141 preschoolers and find a correlation between lack of self-control and 2D:4D digit ratio. Children with low 2D:4D digit ratio are less likely to delay gratification. Low 2D:4D digit ratio may indicate high fetal testosterone. If this hypothesis is true, our finding means high fetal testosterone children are less likely to delay gratification.

    Academic delay of gratification refers to the postponement of immediate rewards by students and the pursuit of more important, temporally remote academic goals. A path model was designed to identify the causal relationships among academic delay of gratification and motivation, self-regulated learning strategies (as specified in the Motivated Strategies for Learning Questionnaire), and grades among 386 Chinese elementary school children. Academic delay of gratification was found to be positively related to motivation and metacognition. Cognitive strategy, resource management, and grades mediated these two factors and were indirectly related to academic delay of gratification.

    Instant noodle waste, one of the main residues of the modern food industry, was employed as feedstock to convert to valuable biofuels. After isolation of used oil from the instant noodle waste surface, the starch residue was converted to bioethanol by Saccharomyces cerevisiae K35 with simultaneous saccharification and fermentation (SSF). The maximum ethanol concentration and productivity was 61.1g/l and 1.7 g/lh, respectively. After the optimization of fermentation, ethanol conversion rate of 96.8% was achieved within 36 h. The extracted oil was utilized as feedstock for high quality biodiesel conversion with typical chemical catalysts (KOH and H2SO4). The optimum conversion conditions for these two catalysts were estimated; and the highest biodiesel conversion rates were achieved 98.5% and 97.8%, within 2 and 3h, respectively. The high conversion rates of both bioethanol and biodiesel demonstrate that novel substrate instant noodle waste can be an attractive biorefinery feedstock in the biofuels industry.

    Full Text Available This study explores why Christians ( N  = 335 use Facebook for religious purposes and the needs engaging with religious content on Facebook gratifies. Individuals who access faith-based content on Facebook were recruited to participate in an online survey through a series of Facebook advertisements. An exploratory factor analysis revealed four primary motivations for accessing religious Facebook content: ministering, spiritual enlightenment, religious information, and entertainment. Along with identifying the uses and gratifications received from engaging with faith-based Facebook content, this research reveals how the frequency of Facebook use, the intensity of Facebook use for religious purposes, and also religiosity predict motivations for accessing this social networking site for faith-based purposes. The data revealed those who frequently use Facebook for posting, liking, commenting, and sharing faith-based content and who are more religious are more likely to minister to others. Frequent use also predicted seeking religious information. The affiliation with like-minded individuals afforded by this medium provides faith-based users with supportive content and communities that motivate the use of Facebook for obtaining spiritual guidance, for accessing religious resources, and for relaxing and being entertained.

    Liu, Xiaoyan; Wang, Lei; Liao, Jiangqun

    2016-01-01

    The presence of delay of gratification (DG) in childhood is correlated with success later in a person's life. Is there any way of helping adults with a low level of DG to obtain similar success? The present research examines how social support helps those low in DG nonetheless to act similarly to those high in DG. This research includes both correlational studies and experiments that manipulate social support as well as both field studies and a laboratory study. The results show that with high social support, employees (Study 1) and university students (Study 2) low in DG report vocational and academic DG behavioral intentions, respectively, similar to those high in DG. Study 3 found that participants low in DG who were primed with high social support expressed job-choice DG similar to those high in the DG. Study 4 controlled for mood and self-image and found that participants low in DG who were primed with high social support expressed more money-choice DG than those high in the DG. Study 5 showed that social support moderated the relationship between DG and actual DG behaviors. These findings provide evidence for a moderating role of social support in the expression of DG behavior. PMID:27047408

    Instant noodles are widely consumed in Asian countries. The Korean population consumed the largest quantity of instant noodles in the world in 2008. However, few studies have investigated the relationship between instant noodles and nutritional status in Koreans. The objective of this study was to examine the association between instant noodle consumption and food and nutrient intake in Korean adults. We used dietary data of 6,440 subjects aged 20 years and older who participated in the Korean National Health and Nutrition Examination Survey III. The average age of the instant noodle consumers (INC) was 36.2 and that of the non-instant noodle consumers (non-INC) was 44.9; men consumed more instant noodles than women (P instant noodles may lead to excessive intake of energy, fats, and sodium but may also cause increased intake of thiamine and riboflavin. Therefore, nutritional education helping adults to choose a balanced meal while consuming instant noodles should be implemented. Additionally, instant noodle manufacturers should consider nutritional aspects when developing new products.

    Full Text Available Text-based conferencing can be both asynchronous (i.e., participants log into the conference at separate times, and synchronous (i.e., interaction takes place in real time. It is thus subject to the same wide variation as the online audio- and video-conferencing methods (see the earlier Reports in this series. Synchronous text-based approaches (e.g., online chat groups and instant messaging systems are highly popular among online users generally owing to their ability to bring together special-interest groups from around the world without cost. In distance education (DE, however, synchronous chat methods are less widely used, owing in part to the problems of arranging for working adults in different time zones to join a discussion group simultaneously. Instant text messaging is more popular among DE users in view of the choice it provides between responding to a message immediately (synchronous communication or after a delay (asynchronous. The different synchronous and asynchronous approaches are likely to become more widely used in parallel with one another, as they are integrated in individual product packages.

Using focus group interviews, the authors explored what factors influence children's ability to delay gratification in using technology. Four specific themes emerged from the interview data: they found (a) fear of punishment, (b) self-directed speech, (c) reinforcement, and (d) parental modeling are effective measures to train children to forgo immediate pleasures of using technology. These findings provided some support for the hypothesis that children's self-control of technology use can be modified and improved. This study suggests methods to leverage and strengthen existing initiatives to promote self-control of technology use for children.

  7. Recent computer attacks via Instant Messaging

    Be cautious of any unexpected messages containing web links even if they appear to come from known contacts. If you happen to click on such a link and if your permission is requested to run or install software, always decline it. Several computers at CERN have recently been broken into by attackers who have tricked users of Instant Messaging applications (e.g. MSN, Yahoo Messenger, etc.) into clicking on web links which appeared to come from known contacts. The links appeared to be photos from ‘friends’ and requested software to be installed. In practice, attacker software was installed and the messages did not come from real contacts. In the past such fake messages were mainly sent by email but now a wider range of applications are being targeted, including Instant Messaging. Cybercriminals are making growing use of fake messages to try to trick you into clicking on Web links which will help them to install malicious software on your computer. Anti-virus software cann...

    This paper explores the advantages and disadvantages of a medical network based on point-to-point communication and a medical network based on Jabber instant messaging protocol. Instant messaging might be, for many people, a convenient way of chatting over the Internet. We will attempt to illustrate how an instant messaging protocol could serve in the best way medical services and provide great flexibility to the involved parts. Additionally, the directory services and presence status offered by the Jabber protocol make it very attractive to medical applications that need to have real time and store and forward communication. Furthermore, doctors connected to Internet via high-speed networks could benefit by saving time due to the data transmission acceleration over Jabber.

    2018-04-01

    In Africa, food-processing industries are emerging fast, especially for cereals. New low-cost extrusion cookers give small enterprises an opportunity to enter the market for processed cereal products, in particular instant, fortified and flavoured mixes. Before engaging in the marketing of these products, consumers' interest needs to be assessed. This study used a combination of affective tests and experimental auctions with 200 consumers in Touba, Senegal, to evaluate four new products with conventional pearl millet flour as the control: instant pearl millet flour, instant pearl millet flour with added dry mango and carrot powder (naturally fortified), and the previous products with added conventional chemical micronutrient fortificants. During affective tests, consumers made little distinction between the five products in appearance, aroma, taste and overall appreciation. The experimental auctions showed that, without providing additional information on the products, there was no difference in 'willingness to pay' (WTP) between them. However, after that information is provided, consumers were willing to pay a modest premium for instant flour, and a large premium for added mango and carrot extract and for added micronutrients, but were not willing to pay a premium if those micronutrients came from natural sources. Income increased overall WTP, while education increased WTP for instant flour. There is a potential market in low-income African countries for instant and fortified cereal food products, but likely in the higher income and education groups. The increased cost needs to be compared to the premiums consumers are willing to pay. In the next step, the new and promising products could be tested in pilot markets, with target consumers. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

  11. An instant dose obtainable in situ calorimeter

    International Nuclear Information System (INIS)

    Kubo, H.; Mento, D.

    1984-01-01

    The development of a computer-linked water calorimeter is described. The advantages of this system are twofold: (i) instant dose determination is possible; and (ii) the calorimeter operation is much simpler than conventional null balance techniques. The entire calorimeter measurement procedure from the set-up to the dose determination for 10 runs was finished in approximately 2 1/2 h. A smaller calorimeter which could be kept in the treatment room for equilibrium, should permit further reduction of the time. The use of a smaller, portable computer would allow local data taking and analysis, eliminating the need for modems, phone lines and long cables. This would lead to a completely self-contained set-up at the treatment room. Although the technique is described for a polystyrene-water calorimeter, it should be equally applicable for a water calorimeter as well as a conventional isolated calorimeter. (author)

    Magnetic labeling of living cells creates opportunities for numerous biomedical applications. Here we describe an instantly cell magnetic labeling method based on ultrasound. We present a detailed study on the ultrasound performance of a simple and efficient labeling protocol for H-22 cells in vitro. High frequency focus ultrasound was investigated as an alternative method to achieve instant cell labeling with the magnetic particles without the need for adjunct agents or initiating cell cultures. Mean diameter of 168 nm dextran-T40 coated superparamagnetic iron oxide (SPIO) nanoparticles were prepared by means of classical coprecipitation in solution in our laboratory. H-22 tumor cells suspended in phosphate-buffered saline (PBS, pH=7.2) were exposed to ultrasound at 1.37 MHz for up to 120 s in the presence of SPIOs. The cellular uptake of iron oxide nanoparticles was detected by prussion blue staining. The viability of cells was determined by a trypan blue exclusion test. At 2 W power and 60 s ultrasound exposure in presence of 410 μg/ml SPIOs, H-22 cell labeling efficiency reached 69.4±6.3% and the labeled cells exhibited an iron content of 10.38±2.43 pg per cell. Furthermore, 95.2±3.2% cells remained viable. The results indicated that the ultrasound protocol could be potentially applied to label cells with large-sized magnetic particles. We also calculated the shear stress at the 2 W power and 1.37 MHz used in experiments. The results showed that the shear stress threshold for ultrasonically induced H-22 cell reparable sonoporation was 697 Pa. These findings provide a quantitative guidance in designing ultrasound protocols for cell labeling. - Highlights: → High frequency focus ultrasound can be used as a safe method for instant magnetic labeling of cells. → 8-16 times increased efficiency can be gained by ultrasound versus that by transfection agents. → Calculation of shear stress around cells provide a quantitative design for ultrasound protocols.

    Full Text Available Instant aloe vera contains phenolic compounds which has antioxidative activity. However, this product is hygroscopic and damaged easily during storage. The critical condition of the instant occurs at the moisture content of 12.52 ± 0.24% (wb. Increasing the moisture content could accelerate oxidation of the phenolic compounds, thus decrease the antioxidative activity. Previous research showed that the antioxidative activity of instant aloe vera could lower the blood glucose. The purpose of this study was to evaluate the hypoglycemic activity of instant aloe vera during storage until the critical condition. The hypoglycemic effect was determined with the in vivo method using diabetic Wistar rats as experimental animals. The diabetic rats were fed with a standard feed combined with instant aloe vera which has been stored at various storage time i.e. 0, 2, 4, 6, 8 weeks and used normal rats fed without instant aloe vera as a control. The blood glucose was analyzed every week until 4 weeks. The research showed that the diabetic rats fed with standard feed without instant aloe vera had high blood glucose (219.40 mg/dL after 4 weeks treatment. Otherwise, the blood glucose of diabetic rats fed with instant aloe vera decreased from 214.00 mg/dL to 97.57 mg/dL after 4 weeks.

    2014-12-01

    Full Text Available The goal of the present study is to explore IM interruption by relating it to media choices and purposes of IM use in the workplace. Two major media choice concepts were: media richness and social influence; while four purposes of IM use were: organization work, knowledge work, socializing, and boundary spanning activities. Data (N = 283 were collected via a combination of convenience and snowball sampling of “computer‐using workers” in Taiwan, based on the Standard Occupational Classification system published by the Taiwan government. Results indicated that media choice works better than purpose of IM use to explain IM interruption. Among them, social influence was the best predictor to IM interruption in the workplace. In addition, instant feedback and personalization provided by IM, and IM usage for the purposes of knowledge work and socializing, also relate to IM interruption in the workplace.

    1991-01-01

    Instant soups are a new group of dried foods and will play an important role in the nutrition of people because they fulfill present and future social consumer requirements. Instrumental neutron activation analysis has been applied in this work to determine the trace elements cesium, cobalt, iron, rubidium, scandium, strontium, silver and zinc in instant and long-time soups from the Greek market. According to our results, instant soups have the same iron content as those reported in the literature for bovine muscle, rice, legumes, porcine muscle and some meat products. Instant soup zinc content is the same as those reported for avian muscle, onions, rice, potatoes and sausages. Moreover the consumption of one plateful of instant soup offers to the human body about 8% of the daily required iron and about 2% of the daily required zinc. (author) 15 refs.; 4 tabs

  17. The Prevalence and Gratification of Nude Self-Presentation of Men Who Have Sex with Men in Online-Dating Environments: Attracting Attention, Empowerment, and Self-Verification.

    2018-01-01

    This study builds on research about the importance of body presentation among men who have sex with men (MSM) by exploring the phenomenon of nude body presentation in online dating environments. In a quantitative survey of N = 9,235 MSM users of a gay online dating site (ODS) in Germany, the prevalence of nude pictures and gratifications sought while displaying them were investigated. About two-thirds of the participants declared that they use nude pictures in their dating profiles, with only small differences in prevalence between members of different ages, education levels, and sexual orientation. Furthermore, the results indicate that the use of nudity is driven by three underlying gratifications: (1) Attracting attention, meaning that nudity is used to accelerate sexual outcomes from online dating use; (2) empowerment, meaning that nudity online serves as an environment for otherwise and elsewhere inhibited forms of body presentation; and (3) self-verification, whereby nudity is used as a means of receiving affirmation from others. Regression analyses are used to investigate associations of these gratifications with sociodemographics and online dating behavior. Findings are discussed in relation to earlier research on self-presentation as well as theories of body importance among gay men. While earlier research has mainly focused on the negative implications of body presentation (e.g., self-objectification; reinforcing standards of beauty), the findings of this study hint that ODS may provide a platform for acts of nude body presentation that are not possible elsewhere and are thus accompanied by empowerment and self-verification.

    2017-03-01

    Consumption of foods made with wheat flour, particularly instant noodles, is increasing in Asia. Given this trend, fortifying wheat flour with vitamins and minerals may improve micronutrient intake in the region. The objective of this review was to understand what is known about fortifying wheat flour used to make instant noodles. A literature review of seven databases was performed using the search terms "noodle" and ("Asian" or "instant"). Grey literature was requested through a food fortification listserv. Articles were title screened first for relevance and duplicity, with exclusion criteria applied during the second round of abstract-level screening. This review considered studies examining simulation, retention, sensory, bioavailability, efficacy, and effectiveness of instant noodles made with fortified wheat flour. Fourteen relevant documents were reviewed for simulation (n=1), retention (n=11), and sensory studies (n=3). The documents revealed that instant noodles produced from fortified wheat flour have potential to improve nutrient intakes, have high retention of most nutrients, and provoke no or minimal changes in sensory characteristics. The available literature indicates that using fortified wheat flour for instant noodle production results in retention of the added nutrients, except thiamin, with no significant sensory change to the final product. Given the rising consumption of instant noodles, production of this item with fortified wheat flour has potential to improve nutrient intakes in Asia. This review provides a resource for the design of a wheat flour fortification program in countries where a large proportion of wheat flour is consumed as instant noodles.

  19. The nature of adolescent competencies predicted by preschool delay of gratification.

    Science.gov (United States)

    Mischel, W; Shoda, Y; Peake, P K

    1988-04-01

    Delay of gratification, assessed in a series of experiments when the subjects were in preschool, was related to parental personality ratings obtained a decade later for 95 of these children in adolescence. Clear and consistent patterns of correlations between self-imposed delay time in preschool and later ratings were found for both sexes over this time span. Delay behavior predicted a set of cognitive and social competencies and stress tolerance consistent with experimental analyses of the process underlying effective delay in the preschool delay situation. Specifically, children who were able to wait longer at age 4 or 5 became adolescents whose parents rated them as more academically and socially competent, verbally fluent, rational, attentive, planful, and able to deal well with frustration and stress. Comparisons with related longitudinal research using other delay situations help to clarify the important features of the situations and person variables involved in different aspects of delay of gratification.

    Change of construction conditions always influences project investment by causing the loss of construction work time and extending the duration. To resolve such problem as difficult dynamic control in work construction plan, this article presents a concept of instant optimization by ways of adjustment operation time of each working procedure to minimize investment change. Based on this concept, its mathematical model is established and a strict mathematical justification is performed. An instant optimization model takes advantage of instant information in the construction process to duly complete adjustment of construction; thus we maximize cost efficiency of project investment.

  3. Delay of Gratification by Chimpanzees (Pan troglodytes) in Working and Waiting Situations

    Science.gov (United States)

    Beran, Michael J.; Evans, Theodore A.

    2009-01-01

    We tested four chimpanzees in a self-control task in which food rewards accumulated as long as they were not eaten. In one condition, the chimpanzees had to perform a computer task that directly led to the delivery of the food rewards. In another condition, working on the computerized task was not required and any such work was not linked to the delivery of rewards. The third condition offered no computerized task (chimpanzees simply waited for food rewards to be delivered). Three of four chimpanzees showed no effect of the work scenario on delay of gratification. The one chimpanzee that showed an influence of work scenario on self-control was the overall poorest performing animal. This animal delayed gratification the longest, however, when work was required and reward delivery was directly linked to that work. Therefore, although there is little evidence linking delay of gratification to work requirements in chimpanzees, chimpanzees with lower overall self-control might benefit from having some work available if reward accumulation is contingent on performing that work.

Inhibition of the numbers of revertants induced from a number of known mutagens indicates that aqueous extracts of instant teas have antimutagenic activity and antioxidative properties, and can inhibit nitrosation reactions. Despite a significant reduction in the amounts of major green tea catechins, quantified using reversed-phase HPLC with electro-chemical detection, no differences in antimutagenicity were observed between the instant teas, a black fermented tea and a green tea. Oxidation of polyphenolic compounds which occurs during the production of instant tea does not therefore decrease the antioxidant, free radical scavenging and antimutagenic properties. This suggests that catechins are not the only compounds responsible for the protective effects of teas.

    We present the Poincare algebra interpolating between instant and light-front time quantizations. The angular momentum operators satisfying SU(2) algebra are constructed in an arbitrary interpolation angle and shown to be identical to the ordinary angular momentum and Leutwyler-Stern angular momentum in the instant and light-front quantization limits, respectively. The exchange of the dynamical role between the transverse angular mometum and the boost operators is manifest in our newly constructed algebra

    Full Text Available Based on the diffusion of innovation (DOI theory (Rogers, 2003, the uses and gratifications (U&G theory, and trust theory, this study investigated the factors that influence the use of Twitter among the Kuwaiti community. The study surveyed Twitter users in Kuwait. A structured online questionnaire was used to collect data, and 463 respondents who provided complete answers participated. Multiple regression analysis was used to examine the effect of three theoretical perspectives on Twitter usage. The result of the analysis showed that Twitter usage is better explained by DOI constructs than by U&G constructs. The findings indicated that the perceived relative advantage from DOI, and the need for information, need to pass time, and need for interpersonal utility from the U&G approach, have a direct positive significant effect on the use of Twitter. None of the trust theory constructs was found to be significant in predicting the general use of Twitter. The study results help Twitter providers and users in individual or organizational contexts to understand what factors generally affect the usage of the Twitter service.

  11. Using Instant Messaging Systems as a Platform for Electronic Voting

    Science.gov (United States)

    Meletiadou, Anastasia; Grimm, Rüdiger

    Many Instant Messaging (IM) systems like Skype or Spark offer ex tended services such as file sharing, VoIP, or a shared whiteboard. As the name suggests, IM applications are predominantly used for spontaneous text-based communication for private or business purposes. In this paper we explore their potential to serve as platforms for secure collaborative applications like electronic contract negotiation, e-payment or electronic voting. Such applications have to deal with challenges like time constraints (“instant” com munication is desired), integration of media channels and the absence of one uni fying “sphere of control” covering all participants. In this paper, we address these challenges by discussing one particular secure collaborative application: secure decision processes for small groups. We provide the following contribu tions: (1) we define three varying scenarios and corresponding security require ments (2) we present an IM-based architecture implementing these scenarios, in cluding a Video-based authentication mechanism, and (3) we discuss poten tial attack patterns.

  12. Instant messaging at the hospital: supporting articulation work?

    Iversen, Tobias Buschmann; Melby, Line; Toussaint, Pieter

    2013-09-01

    Clinical work is increasingly fragmented and requires extensive articulation and coordination. Computer systems may support such work. In this study, we investigate how instant messaging functions as a tool for supporting articulation work at the hospital. This paper aims to describe the characteristics of instant messaging communication in terms of number and length of messages, distribution over time, and the number of participants included in conversations. We also aim to determine what kind of articulation work is supported by analysing message content. Analysis of one month's worth of instant messages sent through the perioperative coordination and communication system at a Danish hospital. Instant messaging was found to be used extensively for articulation work, mostly through short, simple conversational exchanges. It is used particularly often for communication concerning the patient, specifically, the coordination and logistics of patient care. Instant messaging is used by all actors involved in the perioperative domain. Articulation work and clinical work are hard to separate in a real clinical setting. Predefined messages and strict workflow design do not suffice when supporting communication in the context of collaborative clinical work. Flexibility is of vital importance, and this needs to be reflected in the design of supportive communication systems. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

  13. Female gratification, sexual power and safer sex: female sexuality as an empowering resource among women in Rwanda.

    Science.gov (United States)

    Skafte, Ina; Silberschmidt, Margrethe

    2014-01-01

    The gender-based response to HIV in sub-Saharan Africa has tended to reinforce normative stereotypes of women as subordinated, passive and powerless victims, in particular in sexual relations. However, based on qualitative data from Rwanda, this paper argues that such conceptualisations fail to recognise that while women do comply with prevalent social norms, they also challenge these norms and sex becomes a domain in which they can exert power. Female sexuality and sexual gratification - acknowledged and valued by women as well as men - play a pivotal role in the Rwandese mode of sexual intercourse. This provides women a central position in sexual relations, which affords them sexual power. Recognising their sexuality as a resource and drawing upon this 'sexual capital', women are active social agents who have the capacity to manipulate and challenge male dominance in a deliberate strategy both to practice safer sex and to access decision-making power and material resources. This suggests that inherent in sexual relations is a potential for the empowerment of women and the transformation of gender relations.

    2013-03-01

    Scalds and contact burns in children may occur as the result of spillage of hot food and drinks, including instant hot noodles. This study sought to determine the frequency of noodle burns in children and investigate the thermal properties of instant hot noodles. Data on instant hot noodle burns in children were retrieved from the New South Wales Severe Burn Injury Database between 2005 and 2010. Five widely available brands of instant hot noodles, including three cup and two packet varieties, were prepared following the manufacturer's instructions. For each preparation the initial temperature after cooking was recorded, together with the time to cool to 50°C. 291 children sustained instant hot noodle burns over the 6 year study period, representing 5.4% of all children referred to our burns unit. Over a third received inadequate first aid. Cup noodles cooked with boiling water reached the highest temperature of over 80°C and took the longest time to cool to 50°C: on average 52.3 min. Cup noodles in smaller, narrower containers achieved higher post-cooking temperatures compared to noodles in wider, bowel shaped containers. Packet noodles cooked in a Microwave oven attained lower peak temperatures and shorter cooling times compared to cup noodles. Although relatively uncommon in children, instant hot noodle burns often received inadequate first aid. When cooked according to manufacturer's instructions, noodles generally exceeded temperatures sufficient to cause a burn. Consumers and parents need to be aware of the risks of burn when preparing these foods. Crown Copyright © 2012. Published by Elsevier Ltd. All rights reserved.

  17. Early studies of instant-fMRI for routine examination

    2010-01-01

    Authors are developing a low-burden, short-time acquisition method of functional magnetic resonance imaging (fMRI) with 3T machine, named ''Instant-fMRI'', aiming for its application to routine examinations, of which results of early studies on identification of the language hemisphere are reported. Subjects were 10 healthy volunteers (8 males, 2 females, mean age 34.2 y, 8 right-handers) and 5 right-hander patients with brain tumor (4 males, 1 female, mean age 50 y). The machine was GE Signa HDx 3.0T ver. 14, using 8 channel head coil. For Instant-fMRI, T1-weighted imaging sequence for mapping was in fast spoiled gradient recalled acquisition in the steady state (fSPGR) mode (scan time: 1 min 44 sec) and fMRI sequence, in GRE-EPI (scan time: 1 min), which thus required only about 3 min in total. Reference was defined to be the anterior-posterior commissure line, to which parallel sections involving centriciput and cerebellum were acquired. Rest (30 sec)-task (shiritori language game, 30 sec) cycle was to be one in instant-fMRI in contrast to three in the conventional fMRI. Volunteers received both instant-fMRI and conventional fMRI and patients, the former alone. Data were analyzed by GE Brain Wave PA. Right and left hemisphere of the left and right hander, respectively, was identified to be activated by instant-fMRI in 9 of 10 volunteers and in all patients, and by the conventional fMRI, in all volunteers. The instant-fMRI can be a useful examination of other brain functions as well as identifying the language field when acquisition parameters for desired diagnostic purpose are optimized. (T.T.)

    Commercially available instant coffee, Nescafe Excella, contained the radionuclide 40 K. From the instant coffee, sixteen coffee-block radiation sources were successfully fabricated with sufficiently low production dependences. The coffee-block radiation sources were examined their suitability for a radiation protection course. Although a part of radiation counts(cpm) obtained with 1 minute measurement were largely deviated, those determined by 5 minute measurements and five times of 1 minute measurement were less deviated, enabling better comprehension of the three cardinal principles of radiation protection.

  20. A Spatio-Temporal Enhanced Metadata Model for Interdisciplinary Instant Point Observations in Smart Cities

    Directory of Open Access Journals (Sweden)

    Nengcheng Chen

    2017-02-01

    Full Text Available Due to the incomprehensive and inconsistent description of spatial and temporal information for city data observed by sensors in various fields, it is a great challenge to share the massive, multi-source and heterogeneous interdisciplinary instant point observation data resources. In this paper, a spatio-temporal enhanced metadata model for point observation data sharing was proposed. The proposed Data Meta-Model (DMM focused on the spatio-temporal characteristics and formulated a ten-tuple information description structure to provide a unified and spatio-temporal enhanced description of the point observation data. To verify the feasibility of the point observation data sharing based on DMM, a prototype system was established, and the performance improvement of Sensor Observation Service (SOS for the instant access and insertion of point observation data was realized through the proposed MongoSOS, which is a Not Only SQL (NoSQL SOS based on the MongoDB database and has the capability of distributed storage. For example, the response time of the access and insertion for navigation and positioning data can be realized at the millisecond level. Case studies were conducted, including the gas concentrations monitoring for the gas leak emergency response and the smart city public vehicle monitoring based on BeiDou Navigation Satellite System (BDS used for recording the dynamic observation information. The results demonstrated the versatility and extensibility of the DMM, and the spatio-temporal enhanced sharing for interdisciplinary instant point observations in smart cities.

  1. Isolation, gratification, justification: offenders' explanations of child molesting.

    Science.gov (United States)

    Lawson, Louanne

    2003-01-01

    Child sexual abusers' descriptions of their thoughts, behaviors, and relationships were identified by reviewing qualitative research studies published between 1982 and 2001. Offenders used cognitive distortions to meet personal needs, protect themselves from aversive self-awareness, and overcome internal inhibitions against engaging children in sexual activity. Offenders carefully groomed their victims by systematically separating them from their families and peers and socializing them into sexual relationships. Specific cognitive and behavioral processes were used to translate sexual arousal into offending behavior. Offenders justified the abuse by making excuses and redefining their actions as love and mutuality. Throughout the process, offenders exploited the power imbalance inherent in all adult-child relationships. The participants in these studies provided a unique perspective on child sexual abuse that can be used to help victims cope, guide treatment development and evaluation, and suggest new questions for future research.

    1986-08-01

    On the basis of Mischel's (1984) social learning analysis of the process of delay of gratification in children and in line with Bandura's (1977) self-efficacy theory, we developed a model of delay of gratification in adults and tested it on dialysis patients who were continuously required to comply with a stringent regimen of fluid-intake to keep alive. We hypothesized that patients' self-evaluations of their past compliance and their efficacy expectations would be associated with their actual delay behavior. Underlying these process-regulating cognitions would be stable competencies, such as learned resourcefulness (i.e., one's self-control skills). Fifty-three dialysis patients self-evaluated their fluid intake compliance, their efficacy expectations, and their health beliefs. Resourcefulness was assessed by Rosenbaum's Self-Control Schedule. Actual fluid-intake compliance was reliably assessed by the mean body weight increase between dialyses during the 3-month period prior to the study and during two follow-up periods. The results supported the model. On the one hand, self-efficacy expectations were related to persistence with the fluid diet and on the other hand to subjects' self-evaluation of their past adherence behavior as well as to their resourcefulness. Although the path model suggested a causal pattern, the correlational nature of the study precluded any conclusions on cause-effect relationship.

    Full Text Available Instant messaging is one of the communication services that teenagers often use. Referring to its often socializing psychography, many instant messaging brands that compete get market share through marketing communications strategies. The condition of consumer loyalty as the ultimate goal of marketing communication here has its own challenges. Brand switching almost does not cost (zero cost so consumers often use two or more brands at once in their smartphone or gadget. This research builds and tests consumer loyalty model using brand instant messaging by adolescent. This type of quantitative research is selected by Structural Equation Modeling analysis. There are five hypothesis tests with six variables obtained through the results of previous research factor analysis and literature review. The analysis shows that the model is not fit and only two hypotheses accepted the significance of the influence between the variables. The first hypothesis received is the influence between information exposure variable to the level of brand attribute knowledge. The next hypothesis received significance is the influence of consumer satisfaction levels and perceptions of social support to consumer brand user loyalty.   Instant messaging merupakan salah satu layanan komunikasi yang kerap digunakan remaja.

  3. Is It Really Self-Control? Examining the Predictive Power of the Delay of Gratification Task

    Science.gov (United States)

    Duckworth, Angela L.; Tsukayama, Eli; Kirby, Teri A.

    2013-01-01

    This investigation tests whether the predictive power of the delay of gratification task (colloquially known as the “marshmallow test”) derives from its assessment of self-control or of theoretically unrelated traits. Among 56 school-age children in Study 1, delay time was associated with concurrent teacher ratings of self-control and Big Five conscientiousness—but not with other personality traits, intelligence, or reward-related impulses. Likewise, among 966 preschool children in Study 2, delay time was consistently associated with concurrent parent and caregiver ratings of self-control but not with reward-related impulses. While delay time in Study 2 was also related to concurrently measured intelligence, predictive relations with academic, health, and social outcomes in adolescence were more consistently explained by ratings of effortful control. Collectively, these findings suggest that delay task performance may be influenced by extraneous traits, but its predictive power derives primarily from its assessment of self-control. PMID:23813422

Delay behavior was related to a network of conceptually relevant cognitive person variables, consisting of attention deployment strategies during delay, knowledge of delay rules, and intelligence. A positive relationship was demonstrated between concurrent indexes of intelligence, attention deployment, and actual delay time. Moreover, attention deployment, measured as an individual differences variable during the delay process, had a direct, positive effect on delay behavior. Specifically, as the duration of delay and the frustration of the situation increased, children who spent a higher proportion of the time distracting themselves from the tempting elements of the delay situation were able to delay longer. The effect of attention deployment on delay behavior was significant even when age, intelligence, and delay rule knowledge were controlled. Likewise, delay rule knowledge significantly predicted delay time, even when age, attention deployment, and intelligence were controlled.

  6. The effects of activating the money concept on perseverance and preference for delayed gratification in children

    Full Text Available The psychological model of thinking about money assumes that implicit reminders of money lead to self-sufficient motivation. Previous research has demonstrated that children react to money in similar ways to adults. The priming of young children with money related concepts or images has negatively affected their social behaviour and social preferences, leading them to make more individualist and less pro-social choices and be less willing to help others. The aim of this research was to investigate the positive influence of money activation on children’s behaviour. The participants were six to eight year old children who do not yet fully understand the instrumental function of money due to their young age. Two experimental studies were performed, the first of which analysed the effect of perseverance and performance on a challenging task and the second investigated preferences with respect to delaying gratification. Sixty-one children aged 6 took part in the first study and forty-six scout camp participants 6 to 8 years of age were involved in the second experiment. The results support the hypotheses concerning the effects of money activation stating that (1 money activation influences children’s perseverance and effectiveness in difficult individual tasks, and that (2 it increases children’s preferences for delayed gratification. These results suggest that money has a symbolic power which may exert both positive and negative effects on children’s behaviour. Since children between the ages of 6 and 8 do not understand the instrumental function of money fully, certain symbolic meanings of money may have been responsible for the money priming effects. The findings suggest that the symbolic function of money is more primal than its instrumental function and that it probably develops at an earlier stage in life.

  7. A microscopic modeling of the instant coffee effect

    So-called the instant coffee effect is well known in the field of the physics education. The effect is explained that the sound yielded by touching the cup with a spoon is shifted to low-pitched by adulterating bubble owing to putting a spoon of instant coffee into hot water. The phenomenon has been interpreted with the averaged density and compressibility of the fluid in the macroscopic relation for the sound velocity, ν = √(κρ)"-"1. We introduce the linear coupled oscillator model with finite oscillators including the impurity air-mass oscillator. The model may well reproduce the increase in the shift of the eigen frequency accompanying with the amount of bubble.

    To research the statistical properties of human's communication behaviors is one of the highlight areas of Human Dynamics. In this paper, we analyze the instant message data of QICQ from volunteers, and discover that there are many forms of non-Poisson characters, such as inter-event distributions of sending and receiving messages, communications between two friends, log-in activities, the distribution of online time, quantities of messages, and so on. These distributions not only denote the pattern of human communication activities, but also relate to the statistical property of human behaviors in using software. We find out that most of these exponents distribute between -1 and -2, which indicates that the Instant Message (IM) communication behavior of human is different from Non-IM communication behaviors; there are many fat-tail characters related to IM communication behavior.

    After the development of the first phone at the end of 19th century, communication technologies took a great leap forward in the 20th century. With the birth of the "smartphone" in the 21st century, communication technologies exponentially evolved and became an important part of our daily routine. Effective communications between clinicians is critical in medical care and miscommunications are a source of errors. Although telecommunication technologies have proliferated dramatically in the last decade, there is scarce evidence-based information on the use of this technology in medical care. For the purposes of medical communication, we can now consult each other about patients individually and within a group via instant messaging applications by using text messages, photos, audio messages and even videos. In this review, we examine the uses and drawbacks of instant messaging applications in medical communications.

    An empty coffee cup, like an ancient Chinese two-tone bell, emits two distinctly different tones, depending upon where it is tapped. When it is filled with hot water, and some instant coffee is added, however, a whole new set of sounds is heard when the cup is tapped. The pitch rises an octave or more as the foam clears due to the dramatic change in the speed of sound in the bubble-filled liquid. A similar, but smaller, effect was noted in beer by Bragg [The World of Sound (1968)] and in hot chocolate by Crawford [Am. J. Phys. (1982)]. We describe the modes of vibration in a coffee cup and the sound emitted by a coffee cup as filled with instant coffee as the bubble density changes.

    Labeling internal structures within living cells with standard fluorescent probes is a challenging problem. Here, we introduce a novel intracellular staining method that enables us to carefully control the labeling process and provides instant access to the inner structures of living cells. Using a hollow glass capillary with a diameter of <100 nm, we deliver functionalized fluorescent probes directly into the cells by (di)electrophoretic forces. The label density can be adjusted and traced directly during the staining process by fluorescence microscopy. We demonstrate the potential of this technique by delivering and imaging a range of commercially available cell-permeable and nonpermeable fluorescent probes to cells.

    The 99 Tc-content in sup(99m)Tc-pertechnetate separated from 99 Mo by distillation or extraction has been studied with a plastic scintillation detector. The identification of the measured activity was achieved by beta-spectrometry, chemical separation and half-life studies. The frequency distribution of the sup(99)Tc/sup(99m)Tc-ratios in the different samples was observed to be log-normal. The most likely activity ratio was 0.4x10 -6 , the maximum value being 5x10 -6 . The specific activity of ''instant'' pertechnetate is approximately a factor of 60 lower than that normally recorded in pertechnetate derived from daily eluted column generators. The low specific activity of ''instant'' pertechnetate is primarily explained by the long time between separation and usage and secondly by the low yield of Tc in the distillation and extraction processes. In several of the ''instant'' pertechnetate solutions the carrier concentration exceeded the reductive capacity of the stannous ions in ''kits'' with small amounts of Sn(II) in usable form. (T.G.)

  16. Your wish is my command! The influence of symbolic modelling on preschool children’s delay of gratification

    The ability of children to delay gratification is correlated with a range of positive outcomes in adulthood, showing the potential impact of helping young children increase their competence in this area. This study investigated the influence of symbolic models on the self-control of 3-year old children. Eighty-three children were randomly assigned to one of three modelling conditions: personal storytelling, impersonal storytelling, and control. Children were tested on the delay-of-gratification maintenance paradigm both before and after being exposed to a symbolic model or control condition. Repeated measures ANOVA revealed no significant differences between the two storytelling groups and the control group, indicating that the symbolic models did not influence children’s ability to delay gratification. A serendipitous finding showed a positive relationship between the ability of children to wait and their production and accurate use of temporal terms, which was more pronounced in girls than boys. This finding may be an indication that a higher temporal vocabulary is linked to a continuous representation of the self in time, facilitating a child’s representation of the future-self receiving a larger reward than what the present-self could receive.

    Although learning in clinical settings is a key element of nursing education, for many learners these are challenging developmental contexts often marked by isolation and a lack of belongingness. Despite the massive appropriation of mobile instant messaging (MIM) platforms and the connective properties attendant to them, very little is known about their role in and impact on nursing students' clinical learning experiences. To address this gap, the study, which was part of a multinational research project on the use of mobile social media in health professions education in developing countries, examined the use of the instant messaging platform WhatsApp by nursing students during placements and potential associations with socio-professional indicators. The survey involved a total number of 196 nursing students from 5 schools in Oyo State, Nigeria. The findings suggest that students used WhatsApp relatively frequently and they perceived that this platform strongly enhanced their communication with other students and nurses. WhatsApp use during placements was positively associated with students' maintained social capital with peer students, the development of a professional identity, placement satisfaction and with reduced feelings of isolation from professional communities. The determinants that influenced WhatsApp use during placements were perceived usefulness and perceived ease of use. No associations were found between WhatsApp use during placement and age, attitude, subjective norms and placement duration. This study is one of the first of its kind that points to the relevance of mobile instant messaging as part of nursing students' (inter)personal learning environments in clinical settings and, particularly, in the development setting under investigation. Further research is needed to corroborate these findings, to enhance the understanding of the impact mechanisms, and to evaluate a more systematic use of MIM in clinical learning contexts.

    The objective of this study was to present possible formulations for an instant coffee product enriched with chlorogenic acids for the Brazilian market. Formulations were prepared with different concentrations of freeze dried extracts of green Coffea canephora beans (G) added to freeze dried extracts of roasted Coffea arabica (A) and Coffea canephora (C). Medium (M) and dark (D) roasting degrees instant coffee were produced (AM, AD, CM and CD) to obtain four formulations with green extract addition (AMG, ADG, CMG and CDG). Chlorogenic acids were determined by HPLC, with average contents of 7.2 %. Roasted extracts and formulations were evaluated for 5-CQA and caffeine contents (by HPLC), browned compounds (absorbance 420 nm), and antioxidant activity (ABTS and Folin). Coffee brews of the four formulations were also assessed in a lab-scale test by 42 consumers for acceptance of the color, aroma, flavor and body, overall acceptance and purchase intent, using a 10 cm hybrid scale. The formulations obtained acceptance scores of 6.6 and 7.7 for all attributes, thus they were equally acceptable. Greater purchase intent was observed for ADG, CDG and CMG (6.9) in comparison to AMG (6.1). The formulations had, on average, 2.5 times more 5-CQA than the average obtained from conventional commercial instant coffees. In addition to being more economically viable, the formulations developed with C. canephora (CDG and CMG) showed greater antioxidant potential (32.5 g of Trolox/100 g and 13.8 g of gallic acid equivalent/100 g) due to a balance in the amount of bioactive compounds.

    An interlaboratory study was performed to evaluate the method for determining the acid value of instant noodles, based on the Japanese Agricultural Standard (JAS), with extraction of lipid using petroleum ether at a volume of 100 mL to the test portion of 25 g. Thirteen laboratories participated and analyzed 5 test samples as blind duplicates. Statistical treatment revealed that the repeatability (RSDr) of acid value was noodles per unit weight, using the equation [acid value = percent free fatty acids (as oleic) x 1.99] and the extracted lipid contents. This method was shown to have acceptable precision by the present study.

  2. Delay Reduction for Instantly Decodable Network Coding in Persistent Channels With Feedback Imperfections

    Douik, Ahmed S.

    2015-11-05

    This paper considers the multicast decoding delay reduction problem for generalized instantly decodable network coding (G-IDNC) over persistent erasure channels with feedback imperfections. The feedback scenario discussed is the most general situation in which the sender does not always receive acknowledgments from the receivers after each transmission and the feedback communications are subject to loss. The decoding delay increment expressions are derived and employed to express the decoding delay reduction problem as a maximum weight clique problem in the G-IDNC graph. This paper provides a theoretical analysis of the expected decoding delay increase at each time instant. Problem formulations in simpler channel and feedback models are shown to be special cases of the proposed generalized formulation. Since finding the optimal solution to the problem is known to be NP-hard, a suboptimal greedy algorithm is designed and compared with blind approaches proposed in the literature. Through extensive simulations, the proposed algorithm is shown to outperform the blind methods in all situations and to achieve significant improvement, particularly for high time-correlated channels.

    Cell phones with texting capabilities are ubiquitous in the college classroom, and smart phones are becoming increasingly common. These phones are used primarily for personal activities, including social networking, and are expected to remain switched off during instruction. The powerful communication capability of these devices, which could potentially facilitate novel forms of "instructional networking", remains untapped. Instead, special-purpose devices ("clickers") are used when instant feedback is desired in the classroom. A number of technical and behavioral challenges need to be overcome before mobile phones can be used routinely to assist in classroom instruction. This presentation will describe the experience of developing and deploying a mobile web app that enables students to provide instant feedback in the classroom using their mobile phones. The web app leverages existing social networking infrastructure, e.g., using the Twitter microblogging service to aggregate text messages sent by students, to promote classroom interaction. The web app was deployed both in a regular lecture hall and in a computer lab. Topics to be discussed include the technical challenges of deploying a mobile web app in a classroom setting, such as internet accessibility and latency, as well as non-technical issues relating to privacy, student reactions, etc.

    2017-01-01

    Abstract Background: Legislation mandates that clinicians make patients' medical information available digitally. This has resulted in hurriedly installing patient portals that do not fully meet the needs of patients or clinicians. This study examined a specific portal, MyPreventiveCare (MPC), a patient-centered portal designed to promote preventive care to consumers, to elicit recommendations from patients and clinicians about how it could be more beneficial by uncovering their uses and gratifications (U&G). Materials and Methods: In-depth interviews with 31 patients and two clinician focus groups were conducted. Multiple methods were utilized, such as grounded theory coding to develop themes and content analysis to classify responses according to the U&G framework. Results: Four main categories emerged that users desire to be included in health portals: integration with technology (27%), coordination of care (27%), incorporation of lifestyle (26%), and increased control (20%). Additional analysis revealed that health portals are mainly utilized to fulfill cognitive and affective needs, with over 80% of recommendations related to the U&G categories of cognitive and affective needs. Cognitive (60%), affective (21%), social integrative (10%), personal integrative (9%), and tension release (0%). Conclusions: Portals will continue to evolve and become important health communication tools if they address the user's perspective and are inclusive of new technological advances. Specifically, portals must become more user centric and incorporate aspects of the patients' lifestyle and integrate health information technology. PMID:27333468

    Four 'uses and gratifications' studies investigated peoples' reasons for listening to music (Study 1); and whether these reasons differ significantly from those associated with other leisure activities (Study 2). In Study 3, an open-ended, qualitative research design was used to investigate why people listen to music. In Study 4, a cross-sectional design was used to investigate the possibility that people of different ages might listen to music for different reasons. Findings showed that there are a number of reasons why participants listen to music, comparison of which indicated that participants listen to music primarily to manage/regulate their moods. Comparison with other leisure activities indicated that for the most part, listening to music was rated better than other leisure activities at serving an individual's different needs. This versatility may explain why music is so important to people. Evidence was also found to suggest that the reasons for listening to music may change as people grow older. ©2010 The British Psychological Society.

    1986-06-01

    This study examined the differential effects of frustration on normal children and those diagnosed as having Attention Deficit Disorder with Hyperactivity. Each group consisted of 16 boys between the ages of 6 and 8 years who were prematched for age, grade, and classroom placement. All children completed a series of arithmetic problems in order to earn toy rewards. Using a variant of Mischel's (1974) delay-of-gratification paradigm, children were presented with two choice-of-delay conditions in a randomly assigned, counterbalanced sequence: a free-choice conflict situation involving a long-passive or short-active reward delay, and a short-active delay. Results showed that a significantly greater proportion of hyperactive children chose to complete problems for an immediate reward compared to their normal control counterparts (p less than .01). Group differences were no longer apparent in the short-active delay trial. The results are discussed in terms of frustration tolerance and contributing factors such as cognitive-attentional style. Implications for treatment and future directions are delineated.

  9. O2-GIDNC: Beyond instantly decodable network coding

    KAUST Repository

    Aboutorab, Neda

    2013-06-01

    In this paper, we are concerned with extending the graph representation of generalized instantly decodable network coding (GIDNC) to a more general opportunistic network coding (ONC) scenario, referred to as order-2 GIDNC (O2-GIDNC). In the O2-GIDNC scheme, receivers can store non-instantly decodable packets (NIDPs) comprising two of their missing packets, and use them in a systematic way for later decodings. Once this graph representation is found, it can be used to extend the GIDNC graph-based analyses to the proposed O2-GIDNC scheme with a limited increase in complexity. In the proposed O2-GIDNC scheme, the information of the stored NIDPs at the receivers and the decoding opportunities they create can be exploited to improve the broadcast completion time and decoding delay compared to traditional GIDNC scheme. The completion time and decoding delay minimizing algorithms that can operate on the new O2-GIDNC graph are further described. The simulation results show that our proposed O2-GIDNC improves the completion time and decoding delay performance of the traditional GIDNC. © 2013 IEEE.

  10. Synchronicity, instant messaging, and performance among financial traders.

    2011-03-29

    Successful animal systems often manage risk through synchronous behavior that spontaneously arises without leadership. In critical human systems facing risk, such as financial markets or military operations, our understanding of the benefits associated with synchronicity is nascent but promising. Building on previous work illuminating commonalities between ecological and human systems, we compare the activity patterns of individual financial traders with the simultaneous activity of other traders--an individual and spontaneous characteristic we call synchronous trading. Additionally, we examine the association of synchronous trading with individual performance and communication patterns. Analyzing empirical data on day traders' second-to-second trading and instant messaging, we find that the higher the traders' synchronous trading is, the less likely they are to lose money at the end of the day. We also find that the daily instant messaging patterns of traders are closely associated with their level of synchronous trading. This result suggests that synchronicity and vanguard technology may help traders cope with risky decisions in complex systems and may furnish unique prospects for achieving collective and individual goals.

  13. On electrode erosion in fluorescent lamps during instant start

    Energy Technology Data Exchange (ETDEWEB)

    Hadrath, S.

    2006-09-15

    A fluorescent lamp driven with an 'instant start electronic control gear' starts in a glow mode. In the glow mode, which lasts typically for tens of milliseconds, the cathode fall exceeds hundreds of volts. This causes high energy ion bombardment of the electrode which heats the electrode, and induces a transition from glow to arc mode. In the arc mode the electrode emits thermionically and the cathode fall drops to the 12 - 15 V range. Unfortunately, the high energy ion bombardment during the glow mode leads also to intense sputtering of electrode material, including tungsten as well as emitter. Thus, instant started fluorescent lamps often suffer from early failures due to coil fracture. Therefore, the investigation of tungsten erosion during instant start is necessary and was the main goal of this work. The density of neutral atomic tungsten is determined by laser-induced fluorescence (LIF) and optical emission spectroscopy measurements (OES). Investigations are performed on a low-pressure argon dc discharge and on commercial fluorescent lamps. To include the entire temperature profile along the electrode the diffuse and spot operation modes of the dc lamp are studied experimentally and theoretically. The measured dependencies of the cathode temperature along the coil on the discharge and heating parameters are compared with the calculated results. For the first time the tungsten erosion during instant start of commercial fluorescent lamps was experimentally investigated in this work. The erosion process could be related to sputtering. A reconstruction of the temporal evolution of the absolute tungsten population density of the ground state during the glow mode was presented. The sputtered tungsten density increases immediately with the ignition, reaches a maximum where the discharge contracts at the end of the glow mode, and decreases some milliseconds before the glow-to-arc transition takes place. The maximum tungsten density was observed within a

    The co-occurence of posttraumatic stress (PTS) and risky drinking has been demonstrated in diverse populations, including college students. However, the mechanisms underlying this co-occurrence, as well as the protective factors that may reduce risky drinking among trauma-exposed college students have yet to be fully understood in the literature. The present study builds upon self-regulation theories and previous empirical work to determine whether the effects of PTS and coping flexibility on risky drinking were mediated by delay of gratification among trauma-exposed college students. In addition, the potential moderating effect of gender on these relationships was examined. Participants included 624 trauma-exposed college students (68.4% female) attending a public university in the southeast region of the United States. Data were collected through an online survey. The hypothesized model was examined using a multigroup structural equation modeling approach. As hypothesized, PTS had a significant, positive indirect effect on risky drinking through delay of gratification; however, the effect of PTS on delay of gratification was stronger for males than for females. Results also indicated that the indirect effect of coping flexibility on risky drinking through delay of gratification was significant and negative for males and females. Conclusions/Importance: The findings of this study suggest that delay of gratification might be an important mechanism underlying the co-occurrence of PTS and risky drinking. In addition, our results highlight the potential benefits of coping flexibility for college students coping with PTS.

    Full Text Available Instant fried noodles have become one of the food products regularly consumed among people of all socioeconomic levels in both urban and rural areas. Oat bran is rich in β-glucan, a soluble fiber in oat. The objective of this study was to utilize oat bran, produced from dehulled oats by dry milling and cooking extrusion to improve the nutritional quality of wheat noodle and to evaluate the noodle quality. Three types of oat bran concentrate (OBC: OBCXF, OBCXEF, OBC native were used to replace wheat flour in noodle production, each type at the levels of 5, 10, and 15% (w/w. The experimental design was 3×3 factorial randomized complete block design. The flours and products were analyzed for moisture, protein, fat, β- glucan, RVA and color. The texture of the products was determined using texture analyzer and sensory test. Protein contents of OBCXF, XEF, native and wheat flour were 22.05, 23.21, 22.00 and 13.16%, respectively. OBC β-glucan content was 16-17%. Increasing the amount of various OBC in the mixes caused the increase in protein content and β-glucan in the products. The texture of the noodles with 5% replacement with OBC was not significantly different from that of wheat noodle. The tensile force was in the range of 17.10-17.96 g. The sensory acceptability of the noodles replaced with 5-10% OBC was not significantly different from wheat noodle (p<0.05. Noodle with 10% OBC-XEF had the highest scores in texture, elasticity and accept- ability. Thus, instant fried noodle having its wheat partially replaced with 10-15% OBC contained β-glucan in the range of 0.80-1.27 g/serving (50 g, which met the FDA approved health claim which requires 0.75 g/ serving, and contained dietary fiber in the range of 3.0-4.5 g/serving. By using 10-15% OBC in the formulation, it was possible to satisfactorily make instant fried noodles.

    Instant messaging may compromise sleep quality and school performance in adolescents. We aimed to determine associations between nighttime messaging and daytime sleepiness, self-reported sleep parameters, and/or school performance. Students from 3 high schools in New Jersey completed anonymous questionnaires assessing sleep duration, daytime sleepiness, messaging habits, and academic performance. Of the 2,352 students sampled, 1,537 responses were contrasted among grades, sexes, and messaging duration, both before and after lights out. Students who reported longer duration of messaging after lights out were more likely to report a shorter sleep duration, higher rate of daytime sleepiness, and poorer academic performance. Messaging before lights out was not associated with higher rates of daytime sleepiness or poorer academic performance. Females reported more messaging, more daytime sleepiness, and better academic performance than males. There may be an association between text messaging and school performance in this cohort of students. © The Author(s) 2016.

  18. Generalized instantly decodable network coding for relay-assisted networks

    Elmahdy, Adel M.

    2013-09-01

    In this paper, we investigate the problem of minimizing the frame completion delay for Instantly Decodable Network Coding (IDNC) in relay-assisted wireless multicast networks. We first propose a packet recovery algorithm in the single relay topology which employs generalized IDNC instead of strict IDNC previously proposed in the literature for the same relay-assisted topology. This use of generalized IDNC is supported by showing that it is a super-set of the strict IDNC scheme, and thus can generate coding combinations that are at least as efficient as strict IDNC in reducing the average completion delay. We then extend our study to the multiple relay topology and propose a joint generalized IDNC and relay selection algorithm. This proposed algorithm benefits from the reception diversity of the multiple relays to further reduce the average completion delay in the network. Simulation results show that our proposed solutions achieve much better performance compared to previous solutions in the literature. © 2013 IEEE.

    We investigate a possibility of reheating in a scenario of D-brane inflation in a warped deformed conifold background which includes perturbative corrections to throat geometry sourced by a chiral operator of dimension 3/2 in the conformal field theory. The effective D-brane potential, in this case, belongs to the class of nonoscillatory models of inflation for which the conventional reheating mechanism does not work. We find that gravitational particle production is inefficient and leads to reheating temperature of the order of 10 8 GeV. We show that instant preheating is quite suitable to the present scenario and can easily reheat the universe to a temperature which is higher by about 3 orders of magnitude than its counterpart associated with gravitational particle production. The reheating temperature is shown to be insensitive to a particular choice of inflationary parameters suitable to observations.

  1. Instant transformation of learned repulsion into motivational "wanting".

    Robinson, Mike J F; Berridge, Kent C

    2013-02-18

    Learned cues for pleasant reward often elicit desire, which, in addicts, may become compulsive. According to the dominant view in addiction neuroscience and reinforcement modeling, such desires are the simple products of learning, coming from a past association with reward outcome. We demonstrate that cravings are more than merely the products of accumulated pleasure memories-even a repulsive learned cue for unpleasantness can become suddenly desired via the activation of mesocorticolimbic circuitry. Rats learned repulsion toward a Pavlovian cue (a briefly-inserted metal lever) that always predicted an unpleasant Dead Sea saltiness sensation. Yet, upon first reencounter in a novel sodium-depletion state to promote mesocorticolimbic reactivity (reflected by elevated Fos activation in ventral tegmentum, nucleus accumbens, ventral pallidum, and the orbitofrontal prefrontal cortex), the learned cue was instantly transformed into an attractive and powerful motivational magnet. Rats jumped and gnawed on the suddenly attractive Pavlovian lever cue, despite never having tasted intense saltiness as anything other than disgusting. Instant desire transformation of a learned cue contradicts views that Pavlovian desires are essentially based on previously learned values (e.g., prediction error or temporal difference models). Instead desire is recomputed at reencounter by integrating Pavlovian information with the current brain/physiological state. This powerful brain transformation reverses strong learned revulsion into avid attraction. When applied to addiction, related mesocorticolimbic transformations (e.g., drugs or neural sensitization) of cues for already-pleasant drug experiences could create even more intense cravings. This cue/state transformation helps define what it means to say that addiction hijacks brain limbic circuits of natural reward. Copyright © 2013 Elsevier Ltd. All rights reserved.

  2. Instant polysaccharide-based emulsions: impact of microstructure on lipolysis.

    2017-06-21

    The development of emulsion-based products through optimisation of ingredients, reduction in energy-input during manufacture, while fulfilling healthy attributes, are major objectives within the food industry. Instant emulsions can meet these features, but comprehensive studies are necessary to investigate the effect of the initial formulation on the final microstructure and, in turn, on the in vitro lipolysis, comprising the double aim of this work. The instant emulsion is formed within 1.5-3 min after pouring the aqueous phase into the oil phase which contains a mixture of emulsifier (Tween 20), swelling particles (Sephadex) and thickeners (hydroxypropylmethylcellulose, HPMC, and guar gum, GG) under mild shearing (180 rpm). The creation of oil-in-water emulsions is monitored in situ by viscosity analysis, the final microstructure visualised by microscopy and the release of free fatty acids under simulated intestinal conditions quantified by titration. Increasing the concentration and molecular weight (M w ) of GG leads to smaller emulsion droplets due to increased bulk viscosity upon shearing. This droplet size reduction is magnified when increasing the M w of HPMC or swelling capacity of viscosifying particles. In addition, in the absence of the emulsifier Tween 20, the sole use of high-Mw HPMC is effective in emulsification due to combined increased bulk viscosity and interfacial activity. Hence, optimisation of the ingredient choice and usage level is possible when designing microstructures. Finally, emulsions with larger droplet size (>20 μm) display a slower rate and lower extent of lipolysis, while finer emulsions (droplet size ≤20 μm) exhibit maximum rate and extent profiles. This correlates with the extent of emulsion destabilisation observed under intestinal conditions.

    Sodium appetite is an instinct that involves avid specific intention. It is elicited by sodium deficiency, stress-evoked adrenocorticotropic hormone (ACTH), and reproduction. Genome-wide microarrays in sodium-deficient mice or after ACTH infusion showed up-regulation of hypothalamic genes, including dopamine- and cAMP-regulated neuronal phosphoprotein 32 kDa (DARPP-32), dopamine receptors-1 and -2, α-2C- adrenoceptor, and striatally enriched protein tyrosine phosphatase (STEP). Both DARPP-32 and neural plasticity regulator activity-regulated cytoskeleton associated protein (ARC) were up-regulated in lateral hypothalamic orexinergic neurons by sodium deficiency. Administration of dopamine D1 (SCH23390) and D2 receptor (raclopride) antagonists reduced gratification of sodium appetite triggered by sodium deficiency. SCH23390 was specific, having no effect on osmotic-induced water drinking, whereas raclopride also reduced water intake. D1 receptor KO mice had normal sodium appetite, indicating compensatory regulation. Appetite was insensitive to SCH23390, confirming the absence of off-target effects. Bilateral microinjection of SCH23390 (100 nM in 200 nL) into rats' lateral hypothalamus greatly reduced sodium appetite. Gene set enrichment analysis in hypothalami of mice with sodium appetite showed significant enrichment of gene sets previously linked to addiction (opiates and cocaine). This finding of concerted gene regulation was attenuated on gratification with perplexingly rapid kinetics of only 10 min, anteceding significant absorption of salt from the gut. Salt appetite and hedonic liking of salt taste have evolved over >100 million y (e.g., being present in Metatheria). Drugs causing pleasure and addiction are comparatively recent and likely reflect usurping of evolutionary ancient systems with high survival value by the gratification of contemporary hedonic indulgences. Our findings outline a molecular logic for instinctive behavior encoded by the brain with

    2013-01-01

    Full Text Available Instant messenger (IM is one of the most popular Internet applications all over the world. This paper examines the pricing problem of IM based on two-sided market model. IM serves as a two-sided platform, which gets both Internet users and advertisers on board. This paper concludes that IM operator adopts a heavily skewed price structure that favors IM users both under monopolistic case and under horizontal differentiated duopolistic case. When advertising revenue is large enough relatively to marginal cost for serving IM users, IM users can enjoy free service provided by IM operators. The competitive equilibrium of duopolistic case is not necessarily symmetric when advertisers choose singlehoming. Even in the symmetric equilibrium platform would rather deter all advertisers.

    Extensive use of coffee, by one-third of world's population, entails the evaluation of trace element contents in it. Instrumental neutron activation analysis (INAA) was successfully employed to determine the concentration of 20 trace elements (essential, toxic and nonessential) in four samples of coffee beans of various origins and two instant coffee brands most commonly consumed in Pakistan. Base-line values of certain toxic and essential elements in coffee are provided. The daily intake of essential and toxic elements through coffee was estimated and compared with the recommended values. The cumulative intake of Mn is four times higher than the recommended value and that of toxic elements is well below the tolerance limits. (author)

    Protocols that include first trimester screening for fetal chromosome abnormalities have become standard of care throughout the United States. Earlier screening allows for first trimester diagnostic testing in cases found to be at increased risk. However, first trimester screening requires coordination of the nuchal translucency ultrasound screening (NT) and biochemical screening, during early, specific, narrow, but slightly different gestational age ranges. Instant results can often be provided at the time of the NT ultrasound if preceded by the programs that perform the biochemical analyses; this optimizes the benefits of the first trimester approach while improving efficiency and communication with the patient. This article discusses the benefits and logistics of such an approach. Copyright 2010 Elsevier Inc. All rights reserved.

    Instant messaging (IM) has changed the way people communicate with each other. However, the interactive and instant nature of these applications (apps) made them an attractive choice for malicious cyber activities such as phishing. The forensic examination of IM apps for modern Windows 8.1 (or later) has been largely unexplored, as the platform is relatively new. In this paper, we seek to determine the data remnants from the use of two popular Windows Store application software for instant messaging, namely Facebook and Skype on a Windows 8.1 client machine. This research contributes to an in-depth understanding of the types of terrestrial artefacts that are likely to remain after the use of instant messaging services and application software on a contemporary Windows operating system. Potential artefacts detected during the research include data relating to the installation or uninstallation of the instant messaging application software, log-in and log-off information, contact lists, conversations, and transferred files.

    The instant centre frequency (ICF) of RR interval has been proposed as a global index to analyse the sympathovagal interaction in the heart. The aim of this study was to assess the ICF during anaesthesia to test if it can reliably capture the neural control of the cardiovascular system. Twenty-four ASA II or III patients scheduled for cardiac surgery were included in the study. They were allocated in two groups: control, no treatment (group 1, n = 12), and beta-adrenergic blockade by atenolol (group 2, n = 12). Spectra of pulse interval series were computed with a time-frequency method and they were divided into: very low frequency (VLF, 0.000-0.040 Hz), low frequency (LF, 0.050-0.150 Hz) and high frequency (HF, 0.160-0.500 Hz). Normalized power was obtained by dividing the cumulative power within each frequency band (LF or HF) by the sum of LF and HF; the ratio of LF/HF was also calculated. Instant centre frequency is a time-varying parameter that the evolution along time of the gravity centrum of a local spectrum. All spectral indexes were recorded at the following time points: before induction, after induction and before intubation, during intubation, and after intubation. The atenolol group had lower normalized LF and the LF/HF ratio (P ICF was higher in atenolol group at all times. The ICF shifted towards HF frequency after induction and before intubation and shifted towards LF during intubation in both groups. The autonomic nervous system control on the heart through the interaction of sympathetic and parasympathetic reflex mechanisms could be studied by the ICF. The ICF may assess the autonomic cardiac modulation and may provide useful information for anaesthetic management.

    The increased use of the Internet as a new tool in communication has changed the way people interact. This fact is even more evident in the recent development and use of friend-networking sites. However, no research has evaluated these sites and their impact on college students. Therefore, the present study was conducted to evaluate: (a) why people use these friend-networking sites, (b) what the characteristics are of the typical college user, and (c) what uses and gratifications are met by using these sites. Results indicated that the vast majority of college students are using these friend-networking sites for a significant portion of their day for reasons such as making new friends and locating old friends. Additionally, both men and women of traditional college age are equally engaging in this form of online communication with this result holding true for nearly all ethnic groups. Finally, results showed that many uses and gratifications are met by users (e.g., "keeping in touch with friends"). Results are discussed in light of the impact that friend-networking sites have on communication and social needs of college students.

    Development of instant corn rice product has been successfully conducted on a laboratory scale. Corn has high carbohydrate content but low in fiber. The addition of fiber in instant corn rice, intended to improve the functioning of the product, and replace fiber loss during the process. Scale up process of Instant corn rice required to increase the production capacity. Scale up was the process to get identic output on a larger scale based on predetermined production scale. This study aimed to assess the changes and differences in the quality of instant corn rice during scale up. Instant corn rice scale up was done on production capacity 3 kg, 4 kg and 5 kg. Results showed that scale up of instant corn rice producing products with rehydration ratio ranges between 514% - 570%, the absorption rate ranged between 414% - 470%, swelling rate ranging between 119% - 134%, bulk density ranged from 0.3661 to 0.4745 (g/ml) and porosity ranging between 30-37%. The physical quality of instant corn rice on scale up were stable from the ones at laboratory scale on swelling rate, rehydration ratio, and absorption rate but not stable on bulk density and porosity. Organoleptic qualities were stable at increased scale compared on a laboratory scale. Bulk density was higher than those at laboratory scale, and the porosity was lower than those at laboratory scale.

    Increased consumption of instant noodles has recently been reported to be positively associated with obesity and cardiometabolic syndrome in South Korea, which has the highest per capita instant noodle consumption worldwide. This study aimed to investigate the association between instant noodle consumption and cardiometabolic risk factors among college students in Seoul. The study subjects consisted of 3,397 college students (1,782 male; 1,615 female) aged 18-29 years who participated in a health checkup. Information on instant noodle consumption was obtained from the participants' answers to a question about their average frequency of instant noodle intake over the 1 year period prior to the survey. Statistical analysis using a general linear model that adjusted for age, body mass index, gender, family income, health-related behaviors, and other dietary factors important for cardiometabolic risk, showed a positive association between the frequency of instant noodle consumption and plasma triglyceride levels, diastolic blood pressure, and fasting blood glucose levels in all subjects. Compared to the group with the lowest frequency of instant noodle intake (≤ 1/month), the odds ratio for hypertriglyceridemia in the group with an intake of ≥ 3/week was 2.639 [95% confidence interval (CI), 1.393-5.000] for all subjects, while it was 2.149 (95% CI, 1.045-4.419) and 5.992 (95% CI, 1.859-21.824) for male and female students, respectively. In female students, diastolic blood pressure was also higher among more frequent consumers of instant noodles. Our results suggest that frequent consumption of instant noodles may be associated with increased cardiometabolic risk factors among apparently healthy college students aged 18-29 years.

    Determination of the moisture content of instant noodles, currently under discussion by the Codex Alimentarius Commission (CAC) requires 2 methods: one for fried noodles and the other for nonfried noodles. The method to determine the moisture content of fried noodles by drying at 105 degrees C for 2 h used in the Japanese Agricultural Standard (JAS) system of Japan can be applied to this purpose. In the present study, the JAS method for fried noodles was modified to be suitable for nonfried noodles by extending the drying time to 4 h. An interlaboratory study was conducted to evaluate interlaboratory performance statistics for these 2 methods. Ten participating laboratories each analyzed 5 test materials of fried and nonfried noodles as blind duplicates. After removal of outliers statistically, the repeatability (RSDr) and the reproducibility (RSD(R)) of these methods were 1.6-2.6 and 3.9-4.8% for fried noodles, and 0.3-1.5 and 1.3-2.9% for nonfried noodles, respectively.

  17. Partially blind instantly decodable network codes for lossy feedback environment

    Sorour, Sameh

    2014-09-01

    In this paper, we study the multicast completion and decoding delay minimization problems for instantly decodable network coding (IDNC) in the case of lossy feedback. When feedback loss events occur, the sender falls into uncertainties about packet reception at the different receivers, which forces it to perform partially blind selections of packet combinations in subsequent transmissions. To determine efficient selection policies that reduce the completion and decoding delays of IDNC in such an environment, we first extend the perfect feedback formulation in our previous works to the lossy feedback environment, by incorporating the uncertainties resulting from unheard feedback events in these formulations. For the completion delay problem, we use this formulation to identify the maximum likelihood state of the network in events of unheard feedback and employ it to design a partially blind graph update extension to the multicast IDNC algorithm in our earlier work. For the decoding delay problem, we derive an expression for the expected decoding delay increment for any arbitrary transmission. This expression is then used to find the optimal policy that reduces the decoding delay in such lossy feedback environment. Results show that our proposed solutions both outperform previously proposed approaches and achieve tolerable degradation even at relatively high feedback loss rates.

    Research on temporal characteristics of human dynamics has attracted much attentions for its contribution to various areas such as communication, medical treatment, finance, etc. Existing studies show that the time intervals between two consecutive events present different non-Poisson characteristics, such as power-law, Pareto, bimodal distribution of power-law, exponential distribution, piecewise power-law, et al. With the occurrences of new services, new types of distributions may arise. In this paper, we study the distributions of the time intervals between two consecutive visits to QQ and WeChat service, the top two popular instant messaging services in China, and present a new finding that when the value of statistical unit T is set to 0.001s, the inter-event time distribution follows a piecewise distribution of exponential and power-law, indicating the heterogeneous character of IM services users' online behavior in different time scales. We infer that the heterogeneous character is related to the communication mechanism of IM and the habits of users. Then we develop a combination model of exponential model and interest model to characterize the heterogeneity. Furthermore, we find that the exponent of the inter-event time distribution of the same service is different in two cities, which is correlated with the popularity of the services. Our research is useful for the application of information diffusion, prediction of economic development of cities, and so on.

In this paper, we study the distributions of the time intervals between two consecutive visits to QQ and WeChat service, the top two popular instant messaging services in China, and present a new finding that when the value of statistical unit T is set to 0.001s, the inter-event time distribution follows a piecewise distribution of exponential and power-law, indicating the heterogeneous character of IM services users' online behavior in different time scales. We infer that the heterogeneous character is related to the communication mechanism of IM and the habits of users.

    2012-01-01

    Focusing primarily, but not exclusively, on urban and periurban Papua New Guinea (PNG), we discuss the significance of instant ramen noodles to those now known as the “bottom of the pyramid” (BOP). Although instant noodles are remarkable in that they are eaten by virtually everyone in the world, albeit in different amounts and for different reasons, they are marketed in PNG specifically as a “popularly positioned product” (PPP) for the BOP. Cheap, convenient, tasty, filling, and shelf stable, they are a modern addition to Sidney Mintz's classic “proletarian hunger killers” of sugar, tea, and coffee. But, we argue, instant noodles have a distinctive contemporary role: they do more than sustain the poor; they transform them into the aspiring consumers of the BOP. As such, instant noodles can be viewed as an antifriction device, greasing the skids of capitalism as it extends its reach.

    Acrylamide (AA) concentrations in instant noodles (90 samples, covering 10 different brands) from Hebei Province of China were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The instant noodles were sampled from the southern and northern areas of Hebei Province (Shijiazhuang and Tangshan, respectively). The average content of AA for all 10 instant noodle brands was 6-145 µg/kg. The average content of AA in fried instant noodles was 4.47 times of those in non-fried ones, indicating the influence of the frying process. The average content of AA in instant noodles from Shijiazhuang was 1.64 times that of the samples from Tangshan (56 µg/kg). Eighty-four percent of the instant noodle samples in Hebei were contaminated with AA, with an average content of 80 µg/kg. These observations will be helpful for evaluating individual exposure to AA from instant noodles in China.

    Instant whole beans obtained by drying at 25 °C were evaluated for their chemical, physicochemical, nutritional, microbiological, sensory and rehydration characteristics. The proximal composition of instant whole beans was typical of this kind of food, whereas a w and L* , a* and b* values were 0.639, 98.55, -0.28 and -1.52, respectively. In instant whole beans, 75% of the essential amino acids had a value greater or equal to the reference standard for adult humans; the protein quality in terms of chemical score was 95%. Microbiological counts of aerobic mesophilic bacteria, moulds, yeasts and total coliforms of rehydrated instant whole beans were 0.99) to the experimental data for drying of cooked beans and rehydration of instant whole beans, respectively. In the light of the chemical, physicochemical, nutritional, microbiological, sensory and rehydration characteristics of instant whole beans found in this study, drying at 25 °C is recommended for the production of such food.

  11. Exploring the use of text and instant messaging in higher education classrooms

    Full Text Available This article examined how higher education students used text and instant messaging for academic purposes with their peers and faculty. Specifically, comfort level, frequency of use, usefulness, reasons for messaging and differences between peer-to-peer and peer-to-instructor interactions were examined. Students noted that they were very comfortable with using both text and instant messaging. Text messaging was used weekly with instructors and daily with peers. Instant messaging was used rarely with instructors but weekly with peers. Students rated text messaging as very useful and instant messaging as moderately useful for academic purposes. Key reasons cited for using both text and instant messaging included saving time, resolving administrative issues, convenience and ease of use. Text messaging appears to be the preferred mode of communication for students with respect to communicating with both peers and instructors. It is concluded that both text and instant messaging are useful and viable tools for augmenting student's communication among peers and faculty in higher education.

    We replicated and extended Shoda, Mischel, and Peake's (1990) famous marshmallow study, which showed strong bivariate correlations between a child's ability to delay gratification just before entering school and both adolescent achievement and socioemotional behaviors. Concentrating on children whose mothers had not completed college, we found that an additional minute waited at age 4 predicted a gain of approximately one tenth of a standard deviation in achievement at age 15. But this bivariate correlation was only half the size of those reported in the original studies and was reduced by two thirds in the presence of controls for family background, early cognitive ability, and the home environment. Most of the variation in adolescent achievement came from being able to wait at least 20 s. Associations between delay time and measures of behavioral outcomes at age 15 were much smaller and rarely statistically significant.

    Full Text Available The delay of gratification (DoG in children is widely investigated with an experimental procedure originally called the “marshmallow test,” whereas the studies on self-regulation (SR in adolescents and adults usually use self-report questionnaires. Delay discounting (DD measures simplify the DoG procedure and focus on monetary rewards. The aim of this study was to investigate age differences in DoG and DD from childhood to old age using a test that is suitable for both children and adults. Furthermore, investigations were conducted on the association between DoG/DD and two future orientation constructs [future time perspective (FTP and episodic future thinking (EFT] as well as age differences in these constructs. Participants from five age groups (9–14, 18–25, 35–55, 65–80, 80+ participated in the study (N = 96. While we found no age difference for DoG, DD was the lowest [i.e., self-control (SC was the highest] in young/middle adults; however, it was the highest (i.e., SC was the lowest in children and old/oldest adults. Furthermore, we found significant age differences for DD and FTP. As predicted, there were strong correlations between DoG and FTP and between DD and FTP, but not between DoG/DD and EFT. These results indicate that age differences in SR vary across the measures used. Individuals who generally think and act in a future-oriented manner have a stronger ability to delay gratification.

  15. The Effects of Activating the Money Concept on Perseverance and the Preference for Delayed Gratification in Children.

    The psychological model of thinking about money assumes that implicit reminders of money lead to self-sufficient motivation. Previous research has demonstrated that children react to money in similar ways to adults. The priming of young children with money related concepts or images has negatively affected their social behavior and social preferences, leading them to make more individualist and less pro-social choices and be less willing to help others. The aim of this research was to investigate the positive influence of money activation on children's behavior. The participants were 6-8 year old children who do not yet fully understand the instrumental function of money due to their young age. Two experimental studies were performed, the first of which analyzed the effect of perseverance and performance on a challenging task and the second investigated preferences with respect to delaying gratification. Sixty-one children aged 6 took part in the first study and forty-six scout camp participants 6-8 years of age were involved in the second experiment. The results support the hypotheses concerning the effects of money activation stating that (1) money activation influences children's perseverance and effectiveness in difficult individual tasks, and that (2) it increases children's preferences for delayed gratification. These results suggest that money has a symbolic power which may exert both positive and negative effects on children's behavior. Since children between the ages of 6 and 8 do not understand the instrumental function of money fully, certain symbolic meanings of money may have been responsible for the money priming effects. The findings suggest that the symbolic function of money is more primal than its instrumental function and that it probably develops at an earlier stage in life.

    Full Text Available Smartphones have greater computing power than ever before, providing convenient applications to improve our lives. In general, people find it difficult to locate suitable applications and implementing new applications often requires professional skills. In this paper, we propose a new service platform that facilitates the implementation of new applications by composing prebuilt components that provide the context information of mobile devices such as location and contacts. Our platform introduces an innovative concept named context collaboration, in which smartphones exchange context information with each other, which in turn is used to deduct useful inferences. The concept is realized by instant orchestration, which assembles some components and implements a composite component. The interactive communication interface helps a mobile device to communicate with other devices using open APIs, such as SOAP and HTTP (REST. The platform also works in heterogeneous environments, for example, between Android and iOS operating systems. Throughout the platform, mobile devices can act as smart M2M machines with context awareness, enabling intelligent tasks on behalf of users. Our platform will open up a new and innovative pathway for both enhanced mobile context awareness and M2M, which is expected to be a fundamental feature of the next generation of mobile devices.

    Imaging techniques in medicine require fast transfer of images and written information to the clinician in order to allow immediate decision making. This task is markedly alleviated by use of instant film material without need of darkroom, chemical solutions, time consuming processing machines which require space and service. There are several facilities to have the clinical information on transparency film or paper film at all film sizes. Colour film provides special advantages to show the clinician convincing results, however, up to now colour was only seldom used to stress the significance of circumscribed abnormalities in scintiscans. Furthermore colour is a facility to co-ordinate heterogenous information providing a basic structure which is easily seized, so that the conduction of written and pictorial information to the reader is guided by use of colour (identical colour for ROI, curve, numerical results, written text). 35 mm film (colour, black/white) to be used in everyday standard camera types and processed within 2 min is the last step for a complete concept, as it facilitates the minification of images for long-time documentation of medical training (slides) having the data always in the department without the possibility of data misuse during extern film development.

    2015-01-01

    The problem of state feedback control design for discrete-time Takagi-Sugeno (TS) (T-S) fuzzy systems is investigated in this paper. A Lyapunov function, which is quadratic in the state and presents a multi-polynomial dependence on the fuzzy weighting functions at the current and past instants of time, is proposed.This function contains, as particular cases, other previous Lyapunov functions already used in the literature, being able to provide less conservative conditions of control design for TS fuzzy systems. The structure of the proposed Lyapunov function also motivates the design of a new stabilising compensator for Takagi-Sugeno fuzzy systems. The main novelty of the proposed state feedback control law is that the gain is composed of matrices with multi-polynomial dependence on the fuzzy weighting functions at a set of past instants of time, including the current one. The conditions for the existence of a stabilising state feedback control law that minimises an upper bound to the ? or ? norms are given in terms of linear matrix inequalities. Numerical examples show that the approach can be less conservative and more efficient than other methods available in the literature.

    To evaluate the feasibility of using smart phones plus free instant messaging software for remote monitoring of videourodynamics. From November 2011 to October 2012, 85 females with voiding disorders were enrolled for videourodynamic tests. The patients were assigned to videourodynamics remotely monitored by the attending physician by using iPhone/iPad and Skype (group 1) and videourodynamics with the attending physician present (group 2). The procedural time and videourodynamic qualities, assessed by the frequency of adherence to the modified Sullivan criteria, in each group were recorded and compared. There were 44 and 41 patients in group 1 and group 2, respectively. The mean procedural time was comparable between group 1 and group 2 (56.3 vs. 54.4 min, P = 0.25). The frequencies of adherence to the modified Sullivan criteria were similar in each group. The qualities of videourodynamics under the attending physician's remote or direct monitoring were both appropriate. Based on the convenience of Internet, the popularity of smart phones and the intention to make the urologists use their time more efficiently, our study provides remote monitoring as an alternative way for performing videourodynamics. © 2013 Wiley Periodicals, Inc.

    The current study explores how competition and gaming expertise affect the satisfaction of competence needs and gaming gratifications. We demonstrate that competition moderates the effect of gaming expertise on the satisfaction of competence needs, which in turn affects game enjoyment and replay intention. Gaming expertise predicted players' need satisfaction, game enjoyment, and replay intention significantly better in a competitive compared to a noncompetitive context. The effect of gaming expertise on game enjoyment and replay intention was, furthermore, mediated by the satisfaction of competence needs. Finally, gaming expertise positively affected the importance of competition for players' self-esteem only in the competitive gaming context. The present findings demonstrate the importance of competition and gaming expertise for the satisfaction of competence needs, gaming gratifications, and the pursuit of self-esteem during gameplay, attesting to the applicability of self-determination theory to gaming contexts.

    The instant release fraction of a spent nuclear fuel is a matter of concern in the performance assessment of a deep geological repository since it increases the radiological risk. Corrosion studies of two different spent nuclear fuels were performed using bicarbonate water under oxidizing conditions to study their instant release fraction. From each fuel, cladded segments and powder samples obtained at different radial positions were used. The results were normalised using the specific surface area to permit a comparison between fuels and samples. Different radionuclide dissolution patterns were studied in terms of water contact availability and radial distribution in the spent nuclear fuel. The relationship between the results of this work and morphological parameters like the grain size or irradiation parameters such as the burn-up or the linear power density was studied in order to increase the understanding of the instant release fraction formation.

    Instant food is a product produced for convenience for consumer. Qualities are an important attribute of food materials reflecting consumer acceptance. The most problem of instant rice is casehardening during drying process resulted in the longer rehydration time. The objective of this research was to study the qualities of shredded Thai-style instant rice under a combined gas-fired infrared and air convection drying. Additionally, the mathematical models for gas-fired infrared assisted thin-layer drying of shredded Thai-style rice for traditional was investigated. The thin-layer drying of shredded Thai-style rice was carried out under gas-fired infrared intensities of 1000W/m2, air temperatures of 70°C and air velocities of 1 m/s. The drying occurred in the falling rate of drying period. The Page model was found to satisfactorily describe the drying behavior of shredded Thai-style rice, providing the highest R2 (0.997) and the lowest MBE and RMSE (0.01 and 0.18) respectively. A 9 point hedonic test showed in softness and color, but odor and overall acceptance were very similar.

    2015-12-01

    Full Text Available Moisture sorption isotherms of rice-based instant soup mix at temperature range 15–45°C and relative humidity from 0.11 to 0.86 were determined using the standard gravimetric static method. The experimental sorption curves were fitted by five equations: Chung-Pfost, GAB, Henderson, Kuhn, and Oswin. The sorption isotherms of soup mix decreased with increasing temperature, exhibited type II behavior according to BET classification. The GAB, Henderson, Kuhn, and Oswin models were found to be the most suitable for describing the sorption curves. The isosteric heat of sorption of water was determined from the equilibrium data at different temperatures. It decreased as moisture content increased and was found to be a polynomial function of moisture content. The study has provided information and data useful in large-scale commercial production of soup and have great importance to combat the problem of protein-energy malnutrition in underdeveloped and developing countries.

    Reducing salt intake is a cost-effective public health intervention to reduce the global burden of non-communicable disease (NCDs). Ultra-processed foods contribute ~80% of dietary salt in high income countries, and are becoming prominent in low-middle income countries. Instant noodle consumption is particularly high in the Asia Pacific region. The aim of this study was to compare the sodium content of instant noodles sold worldwide to identify potential for reformulation. Analysis was undertaken for 765 instant noodle products from 10 countries using packaged food composition databases of ultra-processed foods compiled by the Global Food Monitoring Group (GFMG) and national shop survey data. Sodium levels were high and variable, within and between countries. Instant noodles in China had the highest mean sodium content (1944 mg/100 g; range: 397-3678/100 g) compared to New Zealand (798 mg/100 g; range: 249-2380 mg/100 g). Average pack size ranged from 57 g (Costa Rica) to 98 g (China). The average packet contributed 35% to 95% of the World Health Organization recommended daily salt intake of <5 g. Forty-one percent of products met the Pacific Island (PICs) regional sodium targets, 37% met the South Africa 2016 targets, and 62% met the UK 2017 targets. This study emphasises a need for stronger regulation and closer monitoring to drive rigorous reformulation of salt in ultra-processed foods.

    Instant ticket purchase gambling (ITPG) is pervasive in Ontario and has features that mimic slot machine play. Previous researchers have reported that ITPG is one preferred activity for at-risk/problem gamblers. In the general Canadian population, rate of participation in ITPG is second only to lottery ticket gambling. Both are particularly favored by youth and seniors. The next cohort of seniors will be Canada's baby boomers, one-third of whom live in Ontario. Secondary analysis of Statistics Canada data revealed that adults in this cohort who buy instant gambling tickets (N = 1781) are significantly different from the complete group of their age peers (N = 4266) in number of activities pursued and frequency of involvement. At-risk/problem gambling prevalence was 10.2% amongst Ontario baby boomers who participate in instant ticket gambling, significantly higher than the 6.7% found amongst the total group of baby boom gamblers. For those who reported experiencing one or more of the Canadian Problem Gambling Index indicators for problem gambling (N = 237), 73% were buying instant tickets. Future research should consider cohort effects and explore combinations of preferred gambling activities that may increase risk for problem gambling. Social policy recommendations include the use of all ITPG venues as key locations for promoting awareness of problem gambling treatment services.

    Full Text Available This research was carried out to study the physical and chemical characteristics of pumpkin Javanese noodle gravy prepared in powder form. The finished product is categorized as an instant product as it only needs to be rehydrated with warm water (60°C before consumption. Five gravy formulations were developed with the incorporation of two types of flour (tapioca and corn flours as the thickening agent. Physical characteristics including colour and swelling properties of the final products were evaluated. For chemical analysis, ash, moisture, protein, crude fiber, fat and carbohydrate compositions were also determined. For physical analysis, all formulations showed similar colour appearance of the gravy powder including lightness (L, redness (a* and yellowness (b*. Pertaining swelling properties of the dried gravy, the water absorption index (WAI values were low (2.0–3.0g/g, while the water solubility index (WSI were moderate (33.0–50.0% when evaluated at both hot (85°C and cold (25°C water. In termn of chemical compositions, carbohydrate and fat content increased and decreased, respectively with the addition of tapioca and corn flours. The moisture content of the instant gravy increased with the increased of corn flour addition. There were differences in fiber and ash content in all formulations, but no specific trend was observed. Finally, protein content remained the same in all formulations. This current finding provided information of the gravy powder produced. Further analysis on the characteristics of the rehydrated pumpkin Javanese noodle gravy will provide a more complete picture of the finished product.

  14. Instantly decodable network coding for real-time device-to-device communications

    Douik, Ahmed

    2016-01-04

    This paper studies the delay reduction problem for instantly decodable network coding (IDNC)-based device-to-device (D2D) communication-enabled networks. Unlike conventional point-to-multipoint (PMP) systems in which the wireless base station has the sufficient computation abilities, D2D networks rely on battery-powered operations of the devices. Therefore, a particular emphasis on the computation complexity needs to be addressed in the design of delay reduction algorithms for D2D networks. While most of the existing literature on IDNC directly extend the delay reduction PMP schemes, known to be NP-hard, to the D2D setting, this paper proposes to investigate and minimize the complexity of such algorithms for battery-powered devices. With delay minimization problems in IDNC-based systems being equivalent to a maximum weight clique problems in the IDNC graph, the presented algorithms, in this paper, can be applied to different delay aspects. This paper introduces and focuses on the reduction of the maximum value of the decoding delay as it represents the most general solution. The complexity of the solution is reduced by first proposing efficient methods for the construction, the update, and the dimension reduction of the IDNC graph. The paper, further, shows that, under particular scenarios, the problem boils down to a maximum clique problem. Due to the complexity of discovering such maximum clique, the paper presents a fast selection algorithm. Simulation results illustrate the performance of the proposed schemes and suggest that the proposed fast selection algorithm provides appreciable complexity gain as compared to the optimal selection one, with a negligible degradation in performance. In addition, they indicate that the running time of the proposed solution is close to the random selection algorithm.

    Iron-deficiency anemia is the most common nutritional problem in Thailand and many developing countries. One of the most sustainable and cost-effective strategies for combating iron deficiency is fortification of staple foods with iron. In this study, the feasibility of fortifying instant noodles with different forms of iron fortificants (ferrous sulfate [FS], ferric sodium ethylenediaminetetraacetic acid [NaFeEDTA], and encapsulated H-reduced elemental iron [EEI] was evaluated, and the fortified noodles were compared with unfortified noodles for changes in physical, chemical, and sensory qualities. Wheat flour used to make instant noodles was fortified to produce a concentration of 5 mg of iron per 50-g serving of instant noodles (one-third of the Thai recommended dietary intake). Analytical data showed that the iron contents were close to 5 mg per serving of noodles fortified with FS, NaFeEDTA, or EEI (5.27 +/- 0.10, 4.27 +/- 0.07, and 5.26 +/- 0.47 mg, respectively). The color quality (measured by L*, lightness, and b* yellowness) of the raw dough sheet and of uncooked and cooked instant noodles fortified with FS was lower than that of the unfortified, but color quality was not changed by the addition of NaFeEDTA. The overall sensory acceptability scores of unfortified and fortified noodles were about 6 ("like slightly"). No metallic odor was observed. During 3 months of storage at room temperature, the iron fortificants did not affect the peroxide level, color, or sensory qualities of the product. Iron fortification of wheat flour used to make instant noodles is feasible. NaFeEDTA is the preferred fortificant because of its nonsignificant effect on the color and sensory quality of the products.

    A novel, rapid and simple analytical method was developed for the quantitative determination of crocin, crocetin and geniposide in soft drink, pastry and instant noodles. The solid samples were relatively homogenized into powders and fragments. The gardenia yellow colorants were successively extracted with methanol using ultrasound-assisted extraction. The analytes were quantitatively measured in the extracts by liquid chromatography coupled with electrospray ionization tandem mass spectrometry. High correlation coefficients (r(2)>0.995) of crocin, crocetin and geniposide were obtained within their linear ranges respectively (50-1000ng/mL, 50-1000ng/mL, 15-240ng/mL) by external standard method. The limits of detection (LODs) were 0.02μg/g for crocin, 0.01μg/g for crocetin and 0.002μg/g for geniposide. And the limits of quantitation (LOQs) were in the ranges of 0.05-0.45μg/g for crocin, and in the ranges of 0.042-0.32μg/g for crocetin, and in the ranges of 0.02-0.15μg/g for geniposide in soft drink, pastry and instant noodles samples. The average recoveries of crocin, crocetin and geniposide ranged from 81.3% to 117.6% in soft drink, pastry and instant noodles. The intra- and inter-day precisions were respectively in the range of 1.3-4.8% and 1.7-11.8% in soft drink, pastry and instant noodle. The developed methods were successfully validated and applied to the soft drink, pastry, and instant noodles collected from the located market in Beijing from China. Crocin, crocetin and geniposide were detected in the collected samples. The average concentrations ranged from 0.84 to 4.20mg/g for crocin, and from 0.62 to 3.11mg/g for crocetin, and from 0.18 to 0.79mg/g for gardenia in various food samples. The method can provide evidences for government to determine gardenia yellow pigments and geniposide in food. Copyright © 2016 Elsevier B.V. All rights reserved.

  19. Zooming in on children's behavior during delay of gratification: Disentangling impulsigenic and volitional processes underlying self-regulation.

    2017-02-01

    When delaying gratification, both motivational and regulatory processes are likely to be at play; however, the relative contributions of motivational and regulatory influences on delay behavior are unclear. By examining behavioral responses during a delay task, this study sought to examine the motivational (anticipatory behavior) and regulatory mechanisms (executive function and self-control strategies) underlying children's self-regulation. The participants, 65 5- to 9-year-old children (M age =7.19years, SD=0.89), were video-recorded during a delay procedure and later coded for anticipatory behaviors (e.g., gazing intensely at the tablet) and self-control strategies. Children also completed two executive function (EF) tasks. We found that anticipatory behavior was curvilinearly related to delay time. Children showing either very low or very high levels of anticipatory behavior were not able to wait the entire time. Furthermore, our results indicated that anticipatory behavior interacted with EF to predict delay time. Specifically, anticipatory behavior was negatively related to delay time only if EF abilities were low. Finally, self-control strategies also interacted with EF to predict children's ability to delay. Spontaneous engagement in self-control strategies such as fidgeting and engagement in alternative activities were beneficial for children with low EF but were unrelated to delay time for children with high EF. Results indicate the value of examining motivational and regulatory influences on delay behavior. Lapses in self-regulation may be due to the combination of powerful impulsigenic (i.e., anticipatory behavior) and weak volitional processes (i.e., EF, self-control strategies). Copyright © 2016.

    Full Text Available Instant high-iron noodles, prepared from wheat flour and high iron brown rice flour, were developed. Three varieties of rice flour, Suphan Buri 90 (SB, Homnin 313 (HW and Homnin 1000 (HP, containing amylose content of 30.40, 19.10 and 15.74% (w/w and iron content of 1.24, 2.04 and 2.22 (mg/100 g respectively, were used to replace wheat flour for instant fried noodle production. To determine the physicochemical properties and acceptability of instant fried noodles,different percentages (30, 40, 50% (w/w of each rice flour sample were used. The instant fried noodles were fortified with ferrous sulphate at levels of 0, 32, 64% iron of RDI per serving. Increasing amount of iron content in the mixtures decreased the L* value, b* value and increased a* value for the color of the instant fried noodle with brown rice flour. The texture characteristic of the noodles with 30, 40, 50% replacement with each variety of brown rice flour were significantly different from those of wheat noodle. Tensile force of the noodles decreased from 11.57±1.30 g to 6.38±1.45 g (SB, 8.36±0.96 g to 5.71±0.57 g (HP and 10.09±1.20 g to 5.46±1.31 g (HW as the rice flour content increased from 30 to 50%. The sensoryacceptability of the noodles made from each variety of 30% brown rice flour fortified with 32% iron of RDI had higher preference scores for elasticity, firmness, color and overall acceptability, than those with 64% iron of RDI. Instant fried noodles with HW and HP brown rice flour were subjected to consumer test using 100 rural primary school children. The frequency percent of the acceptability scores of the noodle with HP and HW were 88 and 84% respectively. Shelf life studyrevealed that the developed products were still acceptable up to 4 months. These products were claimed to be high iron noodle.

    The effects of whole wheat flour (WWF) on pasting properties of instant fried noodle dry mix and quality of final product were investigated in this research. Refined wheat flour in the recipe for instant-fried noodle was replaced by WWF at different levels. The peak and final viscosities were significantly and negatively correlated to WWF substitution level. With increasing WWF level, the hardness, cohesiveness, adhesiveness, and resilience values of instant fried noodles decreased by 11.63, 16.23, 16.67, 20.00%, respectively. WWF darkened noodle's surface color and increased its oil content (26.63%). A porous and less uniformed structure of the WWF instant fried noodles was observed by a scanning electron microscope. Moreover, the WWF incorporation lowered peroxide values of the instant fried noodles during storage. In conclusion, even though the oil content increased, WWF was helpful to inhibit the oil oxidation and produce instant fried noodles with softer texture and less sticky surface. Refined wheat flour in the recipe for instant-fried noodle was replaced by whole wheat flour (WWF), which is rich in dietary fibers, vitamins, and other bioactive compounds. The addition of WWF delayed the retrogradation tendency of starch in the dry mix. WWF-added instant noodles had softer texture, less sticky surface, and lower peroxide value. Based on the results of this study, the refined wheat flour in the recipe for instant-fried noodle could be partially replaced by WWF to make noodles with better texture profile and higher consumer acceptance. © 2017 Wiley Periodicals, Inc.

    Nowadays, there are many instant powdered soups around us. When we make instant powdered soup, sometimes we cannot dissolve powders perfectly. Food manufacturers want to improve this problem in order to make better products. Therefore, they have to measure the state and volume of un-dissolved powders. Earlier methods for analyzing removed the un-dissolved powders from the container, the state of the un-dissolved power was changed. Our research using ultrasonographic image can measure the state of un-dissolved powders with no change by taking cross sections of the soup. We then make 3D soup model from these cross sections of soup. Therefore we can observe the inside of soup that we do not have ever seen. We construct accurate 3D model. We can visualize the state and volume of un-dissolved powders with analyzing the 3D soup models.

    Full Text Available Internet of Things (IoT is a research field that has been continuously developed and innovated in recent years and is also an important driving force for the improvement of people’s life in the future. There are lots of scenarios in IoT where we need to collaborate through devices to complete tasks; that is, a device sends data to other devices, and other devices operate on the aid of the data. These transmitted data are often users’ privacy data, such as medical data and grid data. We propose an instant encrypted transmission based security scheme for such scenarios in IoT. The analysis in this paper indicates that our scheme can guarantee the security of users’ data while ensuring rapid transmission and acquisition of instant IoT data.

    Radiation sensitive films are standard dosimetric tools in radiation therapy. Films are used for machine quality assurance (QA) and treatment planning software evaluation. With the advent of intensity modulated radiation therapy (IMRT), simple and fast imaging technology is needed for patient-specific verification of radiation fields. Conventional radiographic films are often used. Radiochromic films, e.g. Gafchromic films, were recently introduced to the market. But these films have some disadvantages. JP Laboratories have developed a prototype radiochromic film, called SIFID (self-developing, instant film for imaging and dosimetry) with superior performance such that SIFID is unaffected by ambient light for months, stable up to 90 deg. C and can be archived. SIFID is made of polymerizable diacetylene. The film develops blue colour instantly upon absorbing radiation. We evaluated the film for radiation therapy applications. Our preliminary data demonstrate its feasibility as a dosimetric tool for IMRT QA as well as for other applications. (authors)

    A new 35 mm format instant film (Polachrome CS 135) was investigated for suitability in comparison to established conventional colour miniature films. Differences were found, depending on whether the photographic colour material was used for slides or paper prints. Optimum colour results were obtained in monitor photography. The material also proved useful for the recording of paper prints of colour scans, since these were mainly intended for the purpose of transferring the diagnostic findings as a complement to the written report. Priority was therefore given to the immediate availability of the copy, which may be of importance in monitor photography as well. In this respect the new polaroid instant miniature film is clearly superior to those 35 mm colour films that have been used in nuclear medicine up to now. (orig.) [de

    Gulia, Neelam; Khatkar, B S

    2014-04-01

    Instant noodles were prepared from fifteen diverse wheat cultivars varying widely in their flour quality and dough rheology. Dough thermomechanical parameters obtained by Mixolab and flour analytical properties were correlated with the quality of instant noodles including oil uptake, cooking quality and textural attributes. The Mixolab parameters dough development time and dough stability showed significant positive correlation with cooking time, cooked weight, overall acceptability, hardness, springiness, cohesiveness and chewiness of noodles, while negatively correlated with oil uptake and cooking loss, therefore, exhibiting a marked positive effect on quality of instant noodles. Lower protein breakdown represented by C2 torque was also positively related with overall acceptability, hardness, springiness, cohesiveness and chewiness of noodles. Stickiness/adhesiveness of noodles was revealed to be mainly conferred by falling number values (R (2 )= 0.671) and damaged starch (R (2 )= 0.523) content of wheat flour samples. Flour samples with lesser values of protein content, sodium dodecyl sulphate sedimentation volume, thermal stability of proteins, dough stability and dough development time were found to be linked with poor noodle quality. Medium strong flours performed better in noodle making, while weaker flours demonstrated poor noodle quality. Dough rheology of good noodle making flours was characterized with higher dough development time, dough stability, C2, C3, C4 as well as C5 values. Noodles with higher overall acceptability showed a more continuous and uniform protein starch matrix in comparison to the poor counterparts.

    A ready to use food such as instant cream soup become the most suitable choice for those who prefer being practical and also can be applied in any emergency situation such as areas affected by disaster. The adding of milk powder as the main ingredient in cream soup creates a complex bounding of fat and starch which complicates the rehydration process and affects other physical appearance. This research was aimed to find the proper concentration of full cream milk powder concentration to obtain the best characteristics of instant cream soup of dried sweet potato puree. The method used in this research was randomized block design with 6 treatments (12.5%, 15%, 17.5%, 20%, 22.5% and 25%, with an addition of full cream milk powder) and twice repetition. Instant cream soup with 20% of full cream milk powder concentration gave the best physical and chemical characteristics. The physical and chemical characteristic shows that it has 6% water content, 95.47% rehydration value, 18% protein, 20.7% fat, 1080.25 cP viscosity and 30.5% rendement.

  17. Relativistic two-and three-particle scattering equations using instant and light-front dynamics

    1992-01-01

    Starting from the Bethe-Salpeter equation for two particles in the ladder approximation and integrating over the time component of momentum we derive three dimensional scattering integral equations satisfying constraints of unitarity and relativity, both employing the light-front and instant-form variables. The equations we arrive at are those first derived by Weinberg and by Blankenbecler and Sugar, and are shown to be related by a transformation of variables. Hence we show how to perform and relate identical dynamical calculation using these two equations. We extends this procedure to the case of three particles interacting via two-particle separable potentials. Using light-front and instant form variables we suggest a couple of three dimensional three-particle scattering equations satisfying constraints of two and three-particle unitarity and relativity. The three-particle light-front equation is shown to be approximately related by a transformation of variables to one of the instant-form three-particle equations. (author)

    2013-01-01

    In this paper, we study the effect of lossy intermittent feedback loss events on the multicast decoding delay performance of generalized instantly decodable network coding. These feedback loss events create uncertainty at the sender about the reception statues of different receivers and thus uncertainty to accurately determine subsequent instantly decodable coded packets. To solve this problem, we first identify the different possibilities of uncertain packets at the sender and their probabilities. We then derive the expression of the mean decoding delay. We formulate the Generalized Instantly Decodable Network Coding (G-IDNC) minimum decoding delay problem as a maximum weight clique problem. Since finding the optimal solution is NP-hard, we design a variant of the algorithm employed in [1]. Our algorithm is compared to the two blind graph update proposed in [2] through extensive simulations. Results show that our algorithm outperforms the blind approaches in all the situations and achieves a tolerable degradation, against the perfect feedback, for large feedback loss period. © 2013 IEEE.

This research looks at the use of mobile devices to send instant messages that can carry much more information than the short message service (SMS messages, but would be free to use, notwithstanding the price of getting online. We present a prototype IM system that can be used as a viable means of communicating and learning in higher education establishments. There is some evidence to show that learning using mobile devices reduces the formality of the learning experience, and helps engage reluctant learners and raise their self-confidence. In order for the learning process to be successful in online distance learning, unlike in the traditional face-to-face learning, attention must be paid to developing the participants' sense of community within their particular group. Instant messaging – or IM – is a natural medium for online community building and asynchronous/ synchronous peer discussions.

    The instant detection of explosives and explosive-related compounds has become an urgent priority in recent years for homeland security and counter-terrorism applications. Modern techniques should offer enhancement in selectivity, sensitivity, and standoff distances. Miniaturisation, portability, and field-ruggedisation are crucial requirements. This study reports on instant and standoff identification of concealed explosive-related compounds using customized Raman technique. Stokes Raman spectra of common explosive-related compounds were generated and spectrally resolved to create characteristic finger print spectra. The scattered Raman emissions over the band 400:2000cm -1 were compared to infrared absorption using FTIR. It has been demonstrated that the two vibrational spectroscopic techniques were opposite and completing each other. Molecular vibrations with strong absorption in infrared (those involve strong change in dipole moments) induced weak signals in Raman and vice versa. The tailored Raman offered instant detection, high sensitivity, and standoff detection capabilities. Raman demonstrated characteristic fingerprint spectra with stable baseline and sharp intense peaks. Complete correlations of absorption/scattered signals to certain molecular vibrations were conducted to generate an entire spectroscopic profile of explosive-related compounds. This manuscript shades the light on Raman as one of the prevailing technologies for instantaneous detection of explosive-related compounds. Copyright © 2016 Elsevier Ireland Ltd.

    The National Weather Service (NWS) based Instant Messaging service, NWSChat, is used for sharing critical warning decision expertise and other types of significant weather information between the NWS and partners in all levels of government, emergency managers, and the media. NWSChat allows multiple users to send messages to each other in forums known as “chat rooms.” NWSChat is used to enhance decision support during discussions related to high impact weather events, and improve outreach and real-time feed-back from partners. This information is exchanged with the media and emergency response community, who in turn play a key role in communicating the NWS’s hazardous weather messages to the public. NWSChat also provides media and emergency response partners with the ability to communicate significant event reports back to NWS operational personnel, who in turn utilize the information to make effective warning decisions. NWS partners can also use the Service as an efficient means of seeking clarifications and enhancements to the communication stream originating from the NWS. NWSChat will include a wide variety of types of information. Some of this information will include contents of official NWS products available through other NWS systems and thus available to the public. However, other NWSChat content may include preliminary data which has not been screened by NWS for accuracy or applicability; highly technical discussions, some of them speculative, regarding atmospheric or other environmental conditions; and other types of information not intended for a general audience. NWSChat participants are expected to avoid release of information to a broader audience that might be misinterpreted or cause confusion. NWSChat is an enhancement to communications between the NWS and its partners, and is not intended to replace official NWS products or official means of communications. In March 2009, the NWS stood up a Redoubt chatroom just prior to the first eruption

    The consumption of instant noodles is relatively high in Asian populations. It is unclear whether a higher intake of instant noodles is associated with cardiometabolic risk independent of overall dietary patterns. We therefore investigated the association using the Korean National Health and Nutrition Examination Survey IV 2007-2009, a nationally representative cross-sectional survey of the Korean population with a clustered, multistage, stratified, and rolling sampling design. A total of 10,711 adults (54.5% women) 19-64 y of age were analyzed, with adjustment for sampling design complexity. Diet was assessed by using a 63-item food-frequency questionnaire. We identified 2 major dietary patterns with the use of principal components analysis: the "traditional dietary pattern" (TP), rich in rice, fish, vegetables, fruit, and potatoes, and the "meat and fast-food pattern" (MP), with less rice intake but rich in meat, soda, fried food, and fast food including instant noodles. The highest MP quintile was associated with increased prevalence of abdominal obesity (OR: 1.41; 95% CI: 1.05, 1.90), LDL cholesterol ≥130 mg/dL (1.3 g/L) (OR: 1.57, 95% CI 1.26, 1.95), decreased prevalence of low HDL cholesterol (OR: 0.65; 95% CI: 0.53, 0.80), and high triglycerides [≥150 mg/dL (1.5 g/L); OR: 0.73; 95% CI: 0.57, 0.93]. The highest quintile for the TP was associated with decreased prevalence of elevated blood pressure (OR: 0.73; 95% CI: 0.59, 0.90) and marginally lower trends for abdominal obesity (OR: 0.76; 95% CI: 0.58, 0.98; P-trend = 0.06), but neither of the dietary patterns was associated with prevalence of metabolic syndrome. The consumption of instant noodles ≥2 times/wk was associated with a higher prevalence of metabolic syndrome (OR: 1.68; 95% CI: 1.10, 2.55) in women but not in men (OR: 0.93; 95% CI: 0.58, 1.49; P-interaction = 0.04).

    To determine the effectiveness of an instant haw beverage in regulating lipid disturbance, enhancing antioxidant enzyme activity and immune function. Data was collected from 60 hyperlipidemic subjects. In this crossover design, each subject randomly received either the instant haw beverage (100 ml corresponding to 3 g of haw powder or 30 g of fresh haw fruit plus the carrier-guar gum plus some starch) or placebo (guar gum 1.5 g plus some starch as the carrier of the beverage) twice daily. Each supplementation lasted 31 days with a 28-day washout period between treatments. The instant haw beverage significantly reduced total serum cholesterol (9.6%), triglyceride (12.1%), LDLC (18%) while significantly increased SOD activities (7.5%). The placebo was shown to have positive results in some of the lipid profiles, though the effects of the instant haw beverage demonstrated greater significance. Serum triglyceride levels were significantly decreased and SOD activity significantly increased only as subjects were supplemented with the instant haw beverage while no significant changes were seen with placebo. Supplementation with the instant haw beverage positively affects blood lipid profile, antioxidant status and immune function in individuals with hyperlipidemia.

    Observational analysis revealed a concerning frequency of scald burns secondary to instant noodles. A literature review reveals studies with small sample sizes of pediatric populations and analysis of container engineering. The adult cohort, treatments, and short-term outcomes have been neglected. Considering these deficiencies, we reviewed our institution's experience with burns secondary to instant noodles. Patient encounters due to instant noodle burns from January 1, 2007, through May 15, 2011, were reviewed. Demographics, burn characteristics, treatment, length of stay, number of operative interventions, and complications were analyzed. Eight hundred fifty-two patients were seen (460 were admitted) for scald burns of all pathogenesis. Of these, 121 (14%) were seen for burns secondary to noodles (63 men and 58 women). Of these, 48 were older than age 4 (group 1), and 73 were younger than age 4 (group 2). TBSA was 2.34 in group 1 and 1.64 in group 2 (P = .04). The most commonly burned areas in group 1 were extremities (n = 43) and in group 2 were chest (n = 32) and extremities (n = 31). Seven patients in group 1 and two patients in group 2 required operative intervention. Length of stay in groups 1 and 2 were 3.5 and 6 days, respectively. Noodle scald burns cause morbidity at all ages. Pediatric burns due to noodles are frequently managed conservatively but more often necessitate inpatient treatment. The nonpediatric population has larger TBSA and requires more frequent operative intervention. The morbidity of noodle burns is significant. Increased public education and container re-engineering is warranted.

  10. Sensorless control method of instant-heating module for a bidet

    Energy Technology Data Exchange (ETDEWEB)

    2006-07-01

    The three types of temperature control schemes for a bidet system are the mechanical type where both hot water and cold water are supplied to bidet system and users control the outlet water; hot water-tank type where temperature in outlet water is slowly controlled in the hot water tanks; and, instant-heating module type where temperature in outlet water is controlled by a ceramic heater and switching device. All types have advantages and disadvantages. This paper addressed the need for a sensor-less control scheme for an instant-heating module for a bidet, which can control water temperature effectively without using the flow-velocity sensor of the flowing water. The sensor-less control scheme is meant to reduce costs and improve reliability. In this study, a steady state model and simplified model of instant-heating module was developed. An estimation algorithm for the value of flow-velocity of water was also proposed. Experimental work performed under various operating conditions was presented to demonstrate the validity of the proposed sensor-less control scheme. The velocity of the flowing water was estimated by monitoring the changes in outlet water temperature and by analyzing the results against information of inlet water temperature and the switching command for Triac bridge circuit. This information can be readily acquired during the cleaning operation of a bidet system. It was concluded that the proposed method can be easily integrated with existing low-cost control schemes. Future work will focus on mass production of the system, such as developing reliable automatic tuning algorithm to apply the proposed scheme for commercial use. 3 refs., 1 tab., 6 figs.

    Cumulative evidence suggests that coffee consumption may have beneficial effects on metabolic diseases; however, few previous studies have considered the types of coffee consumed and the additives used. We investigated the relationship between coffee consumption and metabolic syndrome (MetSyn) and its components. We analyzed 17,953 Korean adults, aged 19-65 years, using cross-sectional data from the Korean National Health and Nutrition Examination Survey (KNHANES, 2007-2011). Coffee consumption level, types of coffee consumed, and the additives used were assessed based on a food frequency questionnaire and 24-h recall. Demographic and lifestyle factors were assessed using self-administered questionnaires. Data on metabolic biomarkers were obtained from a health examination. Multivariable logistic regression was used to determine the odds ratios of prevalent metabolic syndrome and its components according to frequency and type of coffee consumption. We found that 76% of the subjects were habitual coffee drinkers, most of whom consumed instant coffee mix containing sugar and powder creamer. After multivariable adjustment, the odds ratios (95% CI) comparing those who consumed coffee ≥3 times/day with those who consumed coffee <1 time/week were 1.37 (1.15-1.63) for obesity, 1.33 (1.11-1.59) for abdominal obesity, 1.28 (1.09-1.51) for hypo-HDL cholesterolemia, and 1.37 (1.10-1.72) for metabolic syndrome. Instant-coffee drinkers were observed to have elevated risks of these metabolic conditions. Consumption of coffee, particularly instant coffee mix, may have harmful effects on MetSyn, perhaps partly deriving from excessive intake of sugar and powder creamer.

  2. I want to media multitask and I want to do it now: Individual differences in media multitasking predict delay of gratification and system-1 thinking.

    Schutten, Dan; Stokes, Kirk A; Arnell, Karen M

    2017-01-01

    Media multitasking, the concurrent use of multiple media forms, has been shown to be related to greater self-reported impulsivity and less self-control. These measures are both hallmarks of the need for immediate gratification which has been associated with fast, intuitive 'system-1' decision making, as opposed to more deliberate and effortful 'system-2' decision making. In Study 1, we used the Cognitive Reflection Task (CRT) to examine whether individuals who engage heavily in media multitasking differ from those who are light media multitaskers in their degree of system-1 versus system-2 thinking. In Study 2 we examined whether heavy and light media multitaskers differ in delay of gratification, using the delay discounting measure which estimates the preference for smaller immediate rewards, relative to larger delayed rewards in a hypothetical monetary choice task. We found that heavy media multitaskers were more likely than light media multitaskers to endorse intuitive, but wrong, decisions on the CRT indicating a greater reliance on 'system-1' thinking. Heavy media multitaskers were also willing to settle for less money immediately relative to light media multitaskers who were more willing to wait for the larger delayed reward. These results suggest that heavy media multitaskers have a reactive decision-making style that promotes current desires (money, ease of processing) at the expense of accuracy and future rewards. These findings highlight the potential for heavy media multitaskers to be at risk for problematic behaviors associated with delay discounting - behaviors such as substance abuse, overeating, problematic gambling, and poor financial management.

    The objective of this study was to assess the contribution of iodine intake from iodised household salt, iodised salt in instant noodles, and iodine in ground water in five regions of Indonesia. Secondary data analysis was performed using the 2013 Primary Health Research Survey, the 2014 Total Diet Study, and data from food industry research. Iodine intake was estimated among 2719 children, 10-12 years of age (SAC), 13,233 women of reproductive age (WRA), and 578 pregnant women (PW). Combined estimated iodine intake from the three stated sources met 78%, 70%, and 41% of iodine requirements for SAC, WRA and PW, respectively. Household salt iodine contributed about half of the iodine requirements for SAC (49%) and WRA (48%) and a quarter for PW (28%). The following variations were found: for population group, the percentage of estimated dietary iodine requirements met by instant noodle consumption was significantly higher among SAC; for region, estimated iodine intake was significantly higher from ground water for WRA in Java, and from household salt for SAC and WRA in Kalimantan and Java; and for household socio-economic status (SES), iodine intake from household salt was significantly higher in the highest SES households. Enforcement of clear implementing regulations for iodisation of household and food industry salt will promote optimal iodine intake among all population groups with different diets.

    2015-05-01

    From its introduction to its quindecennial, network coding have built a strong reputation in enhancing packet recovery process and achieving maximum information flow in both wires and wireless networks. Traditional studies focused on optimizing the throughput of the network by proposing complex schemes that achieve optimal delay. With the shift toward distributed computing at mobile devices, throughput and complexity become both critical factors that affect the efficiency of a coding scheme. Instantly decodable network coding imposed itself as a new paradigm in network coding that trades off this two aspects. This paper presents a survey of instantly decodable network coding schemes that are proposed in the literature. The various schemes are identified, categorized and evaluated. Two categories can be distinguished namely the conventional centralized schemes and the distributed or cooperative schemes. For each scheme, the comparison is carried out in terms of reliability, performance, complexity and packet selection methodology. Although the performance is generally inversely proportional to the computation complexity, numerous successful schemes from both the performance and complexity viewpoint are identified.

    Dalia, a wheat-based, particulate containing dairy dessert is popularly consumed as a breakfast food and is also considered as a health food. Though popular throughout Northern parts of the country, its limited shelf-life even under refrigeration imposes severe restrictions on its organized manufacture and marketing. In order to promote dalia dessert as a marketable product, in the present study, a process was developed for manufacture of instant dalia pre-mix, as a dry product with long shelf-life, which could be attractively packaged and easily reconstituted for consumption. During the investigation, the effect of different levels of milk solids and wheat solids was studied on dalia pre-mix quality by employing a central composite rotatable design (CCRD). The suggested formulation had 17.82 % milk solids and 2.87 % wheat solids. This formulation was found to be most appropriate for manufacture of instant dalia pre-mix with predicted sensory scores (Max. 100) of 85.35, 41.98 and 67.27 for mouthfeel, consistency and flavor, respectively; the viscosity of the product was 941.0 cp.

    The ligand GSA (diethylenetriamine pentaacetic acid-galactosyl-human serum albumin) was synthesized by introducing bifunctional chelator DTPA (diethylenetriamine pentaacetic acid) to human serum albumin (HSA) via DTPA anhydride first, and then coupling galactosyl units (2-imino-2-methoxyethyl-thio-galactose) to DTPA-HSA. GSA was labeled with 99 Tc m by using SnCl 2 as reductant and the labeling conditions of 99 Tc m -GSA were optimized. Lyophilized kit of GSA was also developed for instant preparing of 99 Tc m - GSA. The labeling yields in excess of 96% by using both of liquid and lyophilized labeling methods. Biodistribution of 99 Tc m -GSA was investigated in both normal and liver-injury model mice. 99 Tc m -GSA showed high liver uptake in normal mice (>70%ID·g -1 at 30 min after injection). The liver uptake in liver-injury model mice is lower than that of in nor- mal mice (P=0.0324). The promising biological properties of 99 Tc m -GSA combined with the development of reliable and instant lyophilized GSA kit afford the opportunity of liver receptor imaging for routine clinical assessment of hepatocyte function.

    Proton transfer processes and especially excited-state intramolecular proton transfer (ESIPT) are of interest not only in physical studies but in a wide range of biological and chemical researches, since they play an important role in different fundamental reactions. Moreover, occurrence of ESIPT very often causes two-bands emission spectra corresponding to the normal and photoproduct (tautomer) forms of molecular structure. It allows carrying out unique measurement of microcharacteristics in chemical and biological researches by using substances with ESIPT as molecular probes, because its dual emission is very sensitive to parameters of microenvironment. Dual fluorescence signal is very convenient for two wavelength ratiometric measurements as they are more sensitive to variations of sample characteristics. Recently new approach for revealing type of excited state reaction which is based on analysis of dynamic changes of relative intensities in instant spectra of fluorescence ESIPT solutes was suggested and tested for neat solutions. Now we generalize this method on solutions in which ESIPT solute may participate also in creating fluorescent complexes. We demonstrate that relative intensities of instant spectra of fluorescence registered with high time resolution allow to get valuable information referring to type of excited state reaction in which dye may undergo complexation reactions with ions in solvent. In addition we show how it is possible in such case to determine characteristics of complexation as, for example, stability constant and efficiency of complexation.

  12. Instant messages vs. speech: hormones and why we still need to hear each other.

    Seltzer, Leslie J; Prososki, Ashley R; Ziegler, Toni E; Pollak, Seth D

    2012-01-01

    Human speech evidently conveys an adaptive advantage, given its apparently rapid dissemination through the ancient world and global use today. As such, speech must be capable of altering human biology in a positive way, possibly through those neuroendocrine mechanisms responsible for strengthening the social bonds between individuals. Indeed, speech between trusted individuals is capable of reducing levels of salivary cortisol, often considered a biomarker of stress, and increasing levels of urinary oxytocin, a hormone involved in the formation and maintenance of positive relationships. It is not clear, however, whether it is the uniquely human grammar, syntax, content and/or choice of words that causes these physiological changes, or whether the prosodic elements of speech, which are present in the vocal cues of many other species, are responsible. In order to tease apart these elements of human communication, we examined the hormonal responses of female children who instant messaged their mothers after undergoing a stressor. We discovered that unlike children interacting with their mothers in person or over the phone, girls who instant messaged did not release oxytocin; instead, these participants showed levels of salivary cortisol as high as control subjects who did not interact with their parents at all. We conclude that the comforting sound of a familiar voice is responsible for the hormonal differences observed and, hence, that similar differences may be seen in other species using vocal cues to communicate.

    2004-07-01

    The Spent Fuel Stability Project of the European Union aims to develop a model predicting the radionuclide release rate from spent fuel as a function of time for geological disposal conditions. In the first phase of the project, an important aspect consists of the model development focused on defining the instant release fraction (IRF), which represents the fraction of the inventory of safety-relevant radionuclides that may be rapidly released from the fuel and fuel assembly materials at the time of canister breaching. The locations of these preferentially released radionuclides, their quantities, the evidence for their release and proposed estimates of the IRF for the key safety-relevant radionuclides for the case of fuel shortly after discharge from the reactor are the subjects of the present report. Spent fuel assemblies comprise several materials, including uranium oxide, Zircaloy and various steels or nickel alloys used in the structural components of fuel assemblies. Information on the distribution of both activation products and fission products in all these materials must be taken into account in deriving IRF values. Information is presented on the radionuclide distributions in the various materials and IRF values for key radionuclides are proposed. The IRF increases with burnup, particularly above 50 GWd/t IHM . The estimated IRF values are functions of the numbers of spent fuel assemblies in various burnup intervals. Use of bounding fission gas release (FGR) values lead to overestimates of derived IRF values. The problem of uncertainties must be given attention because there is considerable scatter in FGR data, as well as in data from fission product leaching studies. The following approaches and definitions are adopted in this report: a) Best estimate, based on a good understanding of the mechanism and a good quality database; b) Bounding or pessimistic estimate based on data and process understanding that provides a maximum for the range of derived

    People with diabetes mellitus are instructed to clean their skin prior to self-monitoring of blood glucose to remove any dirt or food residue that might affect the reading. Alcohol-based hand sanitizers have become popular when soap and water are not available. The aim of this study was to determine whether a hand sanitizer is compatible with glucose meter testing and effective for the removal of exogenous glucose. We enrolled 34 nonfasting subjects [14 male/20 female, mean ages 45 (standard deviation, 9.4)] years, 2 with diagnosed diabetes/32 without known diabetes]. Laboratory personnel prepared four separate fingers on one hand of each subject by (1) cleaning the second finger with soap and water and towel drying (i.e., control finger), (2) cleaning the third finger with an alcohol-based hand sanitizer, (3) coating the fourth finger with cola and allowing it to air dry, and (4) coating the fifth finger with cola and then cleaning it with the instant hand sanitizer after the cola had dried. Finger sticks were performed on each prepared finger and blood glucose was measured. Several in vitro studies were also performed to investigate the effectiveness of the hand sanitizer for removal of exogenous glucose.z Mean blood glucose values from fingers cleaned with instant hand sanitizer did not differ significantly from the control finger (p = .07 and .08, respectively) and resulted in 100% accurate results. Blood glucose data from the fourth (cola-coated) finger were substantially higher on average compared with the other finger conditions, but glucose data from the fifth finger (cola-coated then cleaned with hand sanitizer) was similar to the control finger. The data from in vitro experiments showed that the hand sanitizer did not adversely affect glucose meter results, but when an exogenous glucose interference was present, the effectiveness of the hand sanitizer on glucose bias (range: 6% to 212%) depended on the surface area and degree of dilution. In our study

    Full Text Available Instant messenger programs such as ICQ are often used by hackers and criminals for illicit purposes and consequently the log files from such programs are of interest in a forensic investigation. This paper outlines research that has resulted in the development of a tool for the extraction of ICQ log file entries. Detailed reconstruction of data from log files was achieved with a number of different ICQ software. There are several limitations with the current design including timestamp information not adjusted for the time zone, data could be altered, and conversations must be manually reconstructed. Future research will aim to address these and other limitations as pointed out in this paper.

    The ubiquicidin 29-41 fragment (UBI) is a cationic antimicrobial peptide. An instant kit formulation was developed for the preparation of 99m Tc-UBI 29-41 in high radiochemical yield and its use as an infection imaging agent in humans was evaluated. The components were selected to produce a direct 99m Tc labeling, presumably to the amine groups of Lys and Arg7. 99m Tc-UBI 29-41 obtained from the lyophilized kit showed radiochemical purity of >97% with an average target/non-target ratio of 2.3±0.6 in positive infection sites at 2 hours. Kits were stable at 4 deg C for over 6 months. (author)

    Full Text Available The paper discusses contemporary condition of French erotic or/and pornographic novel. As social and cultural circumstances seem to put an end to its transgressive potential, the authors of this kind of writing tried, at first, to keep abreast of other media. Nevertheless, the “trash” or “grunge” novel as well as autofictional erotic writings were not able to satisfy the critics. The novels from L’instant erotique collection, written by specialists of erotic art, change the strategy and exploit the new state of cultural relations in which the role of this sort of literature is rather to imitate or to play with erotic or pornographic tradition, creating a new model of reception: very conscious and erudite.

    Full Text Available This article defends the need for transversality when methodologically addressing instant messaging via cellphones as a tool of communication from the point of view of social sciences and humanities. This leads us to the structural approach, which requires supplementary knowledge in fields such as Psychology or History, without losing sight that our study is composed in the areas of Communications and Journalism. We intend to avoid the functional approaches to think about the meaning of mobile phones as a communicative and palliative object of human loneliness. We believe that a part of the so-called applied research, in being useful to society, must take that path if we work as social science or humanities researchers. This issue gains even greater importance knowing that Spain is at the top of leading European countries in terms of the use of social networking systems of communication with software applications such as Whatsapp.

    Instant messaging (IM) has become one of the most popular forms of computer-mediated communication (CMC) and is especially prevalent on college campuses. Previous research suggests that IM users often multitask while conversing online. To date, no one has yet examined the cognitive effect of concurrent IM use. Participants in the present study (N = 69) completed a reading comprehension task uninterrupted or while concurrently holding an IM conversation. Participants who IMed while performing the reading task took significantly longer to complete the task, indicating that concurrent IM use negatively affects efficiency. Concurrent IM use did not affect reading comprehension scores. Additional analyses revealed that the more time participants reported spending on IM, the lower their reading comprehension scores. Finally, we found that the more time participants reported spending on IM, the lower their self-reported GPA. Implications and future directions are discussed.

    Wernli, C.; Kahilainen, J.

    2001-01-01

    The direct ion storage (DIS) dosemeter is a new type of electronic dosemeter from which the dose information for both H p (10) and H p (0.07) can be obtained instantly at the workplace by using an electronic reader unit. The number of readouts is unlimited and the stored information is not affected by the readout procedure. The accumulated dose can also be electronically reset by authorised personnel. The DIS dosemeter represents a potential alternative for replacing the existing film and thermoluminescence dosemeters (TLDs) used in occupational monitoring due to its ease of use and low operating costs. The standard version for normal photon and beta dosimetry, as well as a developmental version for neutron dosimetry, have been characterised in several field studies. Two new small size variations are also introduced including a contactless readout device and a militarised version optimised for field use. (author)

  7. Relativistic instant-form approach to the structure of two-body composite systems

    Krutov, A.F.; Troitsky, V.E.

    2002-01-01

    An approach to the electroweak properties of two-particle composite systems is developed. The approach is based on the use of the instant form of relativistic Hamiltonian dynamics. The main feature of this approach is the method of construction of the matrix element of the electroweak current operator. The electroweak current matrix element satisfies the relativistic covariance conditions and in the case of the electromagnetic current also the conservation law automatically. The properties of the system as well as the approximations are formulated in terms of form factors. The approach makes it possible to formulate relativistic impulse approximation in such a way that the Lorentz covariance of the current is ensured. In the electromagnetic case the current conservation law is also ensured. Our approach gives good results for the pion electromagnetic form factor in the whole range of momentum transfers available for experiments at present time, as well as for the lepton decay constant of pions

    In the present work, the new extraction process of Détente Instantanée Contrôlée DIC (French, for instant controlled pressure drop) was studied, developed, quantitatively and qualitatively compared to the conventional hydrodistillation method for the extraction of essential oils from Algerian myrtle leaves. DIC was used as a thermomechanical treatment, DIC subjecting the product to a high-pressure saturated steam. The DIC cycle ends with an abrupt pressure drop towards vacuum, and this instantly leads to an autovaporization of myrtle volatile compounds. An immediate condensation in the vacuum tank produced a micro-emulsion of water and essential oils. Thus, an ultra-rapid cooling of residual leaves occurred, precluding any thermal degradation. An experimental protocol was designed with 3 independent variables: saturated steam pressure between 0.1 and 0.6 MPa, resulting in a temperature between 100 and 160°C, a total thermal processing time between 19 and 221 s, and between 2 and 6 DIC cycles. The essential oils yield was defined as the main dependent variable. This direct extraction gave high yields and high quality essential oil, as revealed by composition and antioxidant activity (results not shown). After this treatment, the myrtle leaves were recovered and hydrodistilled in order to quantify the essential oil content in residual DIC-treated samples. Scanning electron microscope (SEM) showed some modification of the structure with a slight destruction of cell walls after DIC treatment. Copyright © 2010 Elsevier B.V. All rights reserved.

    Full Text Available In regenerative medicine, there is an approach to avoid expansion of the mesenchymal stem cell (MSC before implantation. The aim of this study was to compare methods for instant MSC therapy by use of a portable, automatic and closed system centrifuge that allows for the concentration of MSCs. The main outcome measures were the amount of MSCs per millilitre of bone marrow (BM, clusters of differentiation (CD, proliferation and differentiation capacities of the MSC. A volume reduction protocol was compared to the traditional laboratory methods of isolation using a Ficoll gradient and native BM. Fifty millilitres of BM were obtained from haematologically healthy male Caucasians (n=10, age 8 to 49 years. The number of colony forming units-fibroblast (CFU-F/ml BM was highest in the centrifuge volume reduction protocol, followed by the native BM (not significant, the centrifuge Ficoll (p=0.042 and the manual Ficoll procedure (p=0.001. The MSC of all groups could differentiate into the mesenchymal lineages without significant differences between the groups. The CD pattern was identical for all groups: CD13+; CD 44+; CD73 +; CD90+; CD105+; HLA-A,B,C+; CD14-; CD34-; CD45-; CD271-; HLA-DR-. In a further clinical pilot study (n=5 with 297 ml BM (SD 18.6, the volume reduction protocol concentrated the MSC by a factor of 14: there were 1.08 x 102 MSC/ml BM (standard deviation (SD 1.02 x 102 before concentration, 14.8 x 102 MSC/ ml BM (SD 12.4 x 102 after concentration, and on average 296 x 102 MSC (SD 248.9 x 102, range 86.4-691.5 x 102 were available for MSC therapy. The volume reduction protocol of the closed centrifuge allows for the highest concentration of the MSC, and therefore, is a promising candidate for instant stem cell therapy.

    BACKGROUND AND HYPOTHESES: A substantial percentage of school absenteeism among children is related to transmissible infection. Rates of transmission can be reduced by hand washing with soap and water, but such washing occurs infrequently. This study tested whether an alcohol-free instant hand sanitizer (CleanHands) could reduce illness absenteeism in school-age children. A 10-week, open-label, crossover study was performed on 420 elementary school-age children (ages 5-12). Students were given a brief orientation immediately prior to the start of the study on the relationship of germs, illness, and hand washing. Each student in the treatment group then received the test product in individual bottles, with instructions to apply one to two sprays to the hands after coming into the classroom, before eating, and after using the restroom, in addition to their normal hand washing with soap and water. The control group was instructed to continue hand washing as normal with non-medicated soap. After 4 weeks of treatment and a 2-week wash-out period, the control and experimental groups were reversed. Data gathered on absenteeism were classified as gastrointestinal or respiratory related and normalized for nonillness-related absenteeism and school holidays. Compared to the hand washing-only control group, students using CleanHands were found to have 41.9% fewer illness-related absence days, representing a 28.9% and a 49.7% drop in gastrointestinal- and respiratory-related illnesses, respectively. Likewise, absence incidence decreased by 31.7%, consisting of a 44.2% and 50.2% decrease in incidence of gastrointestinal- and respiratory-related illnesses, respectively. No adverse events were reported during the study. Daily use of the instant hand sanitizer was associated with significantly lower rates of illness-related absenteeism.

    Full Text Available Cranberries and goji berries were used as natural supplements in extruded instant corn gruels. The effects of additive type and level, as well as extrusion-cooking screw speed on selected properties of extrudates were tested. Corn grit was used as the base raw materials and dry and ground goji berries and cranberries were added at 1, 2, 3, 4 and 5%. Extrusion-cooking of blends was performed with a single screw extruder at temperature ranged 125-135°C using various screw speed during processing. Extrudates were ground below 1 mm for instant gruels. Water absorption, water solubility, as well as colour profile were tested. The results showed that the highest water absorption was evaluated for instant gruels consist the highest amount of goji berries extruded at the highest screw speed during processing, while cranberries addition have no significant effect on water absorption. Increasing amount of dry cranberries and goji berries in the recipe affected on lowering the water solubility of the extrudates. Significant effect of fruits on color coordinates was observed. Increasing amount of dry berries lowered lightness L* and yellowness of instant gruels, especially when goji berries were used in the recipe. Increasing the screw speed during processing decreased intensity b* values.

    The instant release of fission products from high burn-up UO{sub 2} fuels and one MOX fuel was investigated by means of leach tests. The samples covered PWR and BWR fuels at average rod burn-up in the range of 45–63 GWd/t{sub HM} and included clad fuel segments, fuel segments with opened cladding, fuel fragments and fuel powder. The tests were performed with sodium chloride – bicarbonate solutions under oxidizing conditions and, for one test, in reducing Ar/H{sub 2} atmosphere. The iodine and cesium release could be partially explained by the differences in sample preparation, leading to different sizes and properties of the exposed surface areas. Iodine and cesium releases tend to correlate with FGR and linear power rating, but the scatter of the data is significant. Although the gap between the fuel and the cladding was closed in some high burn-up samples, fissures still provide possible preferential transport pathways. - Highlights: • Leach tests were performed to study the instant release of fission products from high burn-up UO{sub 2} fuels and one MOX fuel. • In these tests, the fission gas release given by the operator was a pessimistic estimator of the iodine and cesium release. • Iodine and cesium release is proportional to linear power rating beyond 200 W cm{sup −1}. • Closure of the fuel-cladding gap at high burn-up slows down the release. • The release rate decreases following an exponential equation.

    Comprehensible knowledge of the excited-state proton transfer processes in organic compounds is overwhelmingly important not only for physics, but also chemistry and Life Sciences, since they play a key role in main processes of photosynthesis and functioning of biological organisms. Moreover compounds with Excited-State Intramolecular Proton Transfer (ESIPT) are in the focus of the interest of scientists throughout the world, because dual fluorescence spectra of such objects corresponding to two forms of molecular structure (normal and photoproduct) are very sensitive to characteristics of molecular microenvironment. This property allows to use such substances as fluorescent probes for diverse applications in chemistry and Life Sciences. But at the same time studying of proton transfer processes is not simple, because this process is characterized by extremely fast times (on picoseconds time scale and less order) and very often contribution of reverse reactions is essentially complicates an interpretation of observed properties of dual fluorescence. Hence, understanding of a role of reversible reactions is crucial for a comprehensive description of all processes accompanying excited state reactions. We discuss new approach for treatment ESIPT reaction on the basis of experimentally measured instant spectra of dual fluorescence and temporal behavior of ratiometric signal of normal to tautomer form intensities. Simple analytical expressions show in transparent way how to distinguish a degree of reverse reaction contribution to ratiometric signal. A validation of the approach under consideration is fulfilled with two different flavonols – 3-hydroxyflavone and 4′-(Dimethylamino)-3-hydroxyflavone – representing two extreme cases in affecting reversible reaction on dual emission. A comparing of new approach and traditional method when we analyze kinetics of separate the N* and T* fluorescence bands decays, has been carried out. - Highlights: • The excited

    Highlights: • Flow with Negligible Disturbances, or first type, with length L ND = L 1 . • Flow with Small Disturbances, or second type, with length L SD . • Total length, L ND + L SD = L 2 , is in agreement with average Undisturbed flow, L U . • Flow with Coherent Vortices, or third type, with length L CV . • Total length, L ND + L SD + L CV = L 3 , is in agreement with average Potential core, L P . - Abstract: The paper is aimed at investigating the influence of the Reynolds number on the instant flow evolution of a rectangular free jet of air in the range of Reynolds numbers from Re = 35,300 to Re = 2,200, where the Reynolds number, Re, is defined according to the hydraulic diameter, D, of a rectangular slot of height H, equal to about D = 2H. The Particle Image Velocimetry (PIV) technique allows obtaining the instant PIV visualizations on the central symmetry section of the rectangular jet. The visual inspection of the instant frames with one and two vortices, except for Re = 35,300 where only one vortex images are detected, shows that after the jet exit is present the Flow with Constant Instant Height, with a length L CIH which increases with the decrease of the Reynolds number, from a ratio L CIH /H equal to L CIH /H = 0.9 at Re = 35,300 to L CIH /H = 4.0 at Re = 2,200. The instant PIV measurements, carried out at several distances from the jet exit, show that the variations of the ratio U/U ‾ 0 of the centerline instant velocity, U, to the exit average velocity, U ‾ 0 , remain below ±4% for a length L CIV , defining the Flow with Constant Instant Velocity on the centerline. The ratio L CIV /H increases from L CIV /H = 1.1 at Re = 35,300 to L CIV /H = 4.1 at Re = 2,200 and is quite similar to L CIH /H. The instant PIV measurements of the centerline turbulence intensity, Tu, show that its variations remain below ±4% for a length L CIT , defining the Flow with Constant Instant Turbulence on the centerline. The ratio L CIT /H is equal to L CIV /H

    In the present study, initial microbial load of instant cup noodle (ICN) was investigated and gamma irradiation applied to develop immuno-compromised patients food for their safe consumption. The initial microbial population of dried vegetable and meat, and noodle was below the detection limit (1 log CFU/g); however, that of seasoning powder was just above 4 log CFU/g. Moreover, rehydrated-ICN with water at 100 °C still show above 3 log CFU/g of microbial load, which indicates the need for an additional process to control microbial safety of the seasoning powder. The total aerobic bacteria in seasoning powder and rehydrated-ICN could be controlled with 17 kGy gamma irradiation. This result referred 17 kGy gamma irradiation could reach ‘practical sterility’ of ICN. The overall difference in sensory properties between the non-irradiated and irradiated ICN was insignificant. Thus, gamma irradiation could improve the microbial quality of ICN, and reduce the risk of infection posed by the seasoning powder, without any adverse effects on their sensory quality. These results suggest that gamma-irradiated ICN can be used as a snack food for immuno-compromised patients.

    Full Text Available Abstract The objective was to develop instant noodles (IN made by atmospheric and vacuum frying processes, with addition of 10% of three different sources of resistant starch: resistant starch type 2 (RS2, resistant starch type 3 (RS3 and green banana flour (GBF aiming the increasing of the fibre content. The IN obtained by atmospheric frying lost water faster and absorbed more fat. However, for both frying treatments, the RS3 noodles absorbed the least amount of oil. The greatest loss of RS occurred during the cooking stage. RS2 and GBF noodles presented a loss of RS of around 30% during steam cooking, while the RS3 approximately 18%. The frying process decreased RS content of noodles, however, during both frying process, the samples with the highest RS content at all frying times were noodles containing RS3. When comparing products obtained after 90 and 120 s of atmospheric and vacuum frying, respectively, it was observed that, although the frying time in vacuum process was longer, higher RS values were obtained for the three different formulations. The vacuum frying process has advantages due to the lower fat absorption (3% less, lighter colour and a reduced conversion of RS to digestible starch, compared to atmospheric frying.

    Drying process is an essential step to produce instant noodles. Yet, the industries especially Small and Medium Enterprises (SMEs), is seeking for an efficient method to dry the noodles. This paper discusses the performance of an invented drying system which employed heating and humidifying process. The drying system was tested using 30 kilogram of the raw noodle known as “Mee Siput”. Temperature controlled system were used in the study to control the temperature of the drying process and prevent the dried noodles from damage by maintaining the temperature of lower than 80°C. The analysis shows that the system was drastically decreased the humidity from 80% to 40% just after 200 minutes of the drying process. The complete dehydration time of noodle has also decreased to only 4 hours from 16 hours when using traditional drying system without sacrificed the good quality of the dried noodle. In overall, the invented system believed to increase the production capacity of the noodle, reduce cost of production which would highly beneficial for Small Medium Industries (SMEs) in Malaysia.

    2014-06-01

    The problem of minimizing the decoding delay in Generalized instantly decodable network coding (G-IDNC) for both perfect and lossy feedback scenarios is formulated as a maximum weight clique problem over the G-IDNC graph in. In this letter, we introduce a new lossy G-IDNC graph (LG-IDNC) model to further minimize the decoding delay in lossy feedback scenarios. Whereas the G-IDNC graph represents only doubtless combinable packets, the LG-IDNC graph represents also uncertain packet combinations, arising from lossy feedback events, when the expected decoding delay of XORing them among themselves or with other certain packets is lower than that expected when sending these packets separately. We compare the decoding delay performance of LG-IDNC and G-IDNC graphs through extensive simulations. Numerical results show that our new LG-IDNC graph formulation outperforms the G-IDNC graph formulation in all lossy feedback situations and achieves significant improvement in the decoding delay especially when the feedback erasure probability is higher than the packet erasure probability. © 2012 IEEE.

  5. Delay reduction in persistent erasure channels for generalized instantly decodable network coding

    2013-06-01

    In this paper, we consider the problem of minimizing the decoding delay of generalized instantly decodable network coding (G-IDNC) in persistent erasure channels (PECs). By persistent erasure channels, we mean erasure channels with memory, which are modeled as a Gilbert-Elliott two-state Markov model with good and bad channel states. In this scenario, the channel erasure dependence, represented by the transition probabilities of this channel model, is an important factor that could be exploited to reduce the decoding delay. We first formulate the G-IDNC minimum decoding delay problem in PECs as a maximum weight clique problem over the G-IDNC graph. Since finding the optimal solution of this formulation is NP-hard, we propose two heuristic algorithms to solve it and compare them using extensive simulations. Simulation results show that each of these heuristics outperforms the other in certain ranges of channel memory levels. They also show that the proposed heuristics significantly outperform both the optimal strict IDNC in the literature and the channel-unaware G-IDNC algorithms. © 2013 IEEE.

    For several years, the completion time and the decoding delay problems in Instantly Decodable Network Coding (IDNC) were considered separately and were thought to completely act against each other. Recently, some works aimed to balance the effects of these two important IDNC metrics but none of them studied a further optimization of one by controlling the other. In this paper, we study the effect of controlling the decoding delay to reduce the completion time below its currently best known solution. We first derive the decoding-delay-dependent expressions of the users\\' and their overall completion times. Although using such expressions to find the optimal overall completion time is NP-hard, we use a heuristic that minimizes the probability of increasing the maximum of these decoding-delay-dependent completion time expressions after each transmission through a layered control of their decoding delays. Simulation results show that this new algorithm achieves both a lower mean completion time and mean decoding delay compared to the best known heuristic for completion time reduction. The gap in performance becomes significant for harsh erasure scenarios.

    In this study, research on the development of a puffed wheat snack using the instant controlled pressure drop (DIC) process was carried out. Snack products were produced by expanding moistened wheat under various DIC processing conditions in order to obtain adequate puffing, followed by drying in a hot air dryer. The effects of operational variables such as wheat initial moisture content (11-23% w/w, wet basis), processing pressure (3-5 × 10 2 kPa) and processing time (3-11 min) on the physical (density, color and textural characteristics) and sensory properties of the product were investigated. The physical properties of the wheat snack were most affected by changes in processing pressure, followed by processing time and wheat moisture content. Increasing processing pressure and time often improved expansion and textural properties but led to darkening of the raw wheat color. The most acceptable snack in terms of physical properties was obtained at the lowest wheat moisture content. Sensory analysis suggested that consumer acceptability was optimal for wheat snacks produced at higher processing pressure, medium processing time and lower moisture content. The most desirable conditions for puffed wheat snack production using the DIC process were determined as 11% (w/w) of wheat moisture content, 5 × 10 2 kPa of processing pressure and 7 min of processing time. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    2014-09-01

    In this paper, we consider the problem of minimizing the maximum broadcast decoding delay experienced by all the receivers of generalized instantly decodable network coding (IDNC). Unlike the sum decoding delay, the maximum decoding delay as a definition of delay for IDNC allows a more equitable distribution of the delays between the different receivers and thus a better Quality of Service (QoS). In order to solve this problem, we first derive the expressions for the probability distributions of maximum decoding delay increments. Given these expressions, we formulate the problem as a maximum weight clique problem in the IDNC graph. Although this problem is known to be NP-hard, we design a greedy algorithm to perform effective packet selection. Through extensive simulations, we compare the sum decoding delay and the max decoding delay experienced when applying the policies to minimize the sum decoding delay and our policy to reduce the max decoding delay. Simulations results show that our policy gives a good agreement among all the delay aspects in all situations and outperforms the sum decoding delay policy to effectively minimize the sum decoding delay when the channel conditions become harsher. They also show that our definition of delay significantly improve the number of served receivers when they are subject to strict delay constraints.

    Full Text Available Background. Formalin, a traditionally preferred fixative in the field of pathology, has restricted usage in private settings. Since its toxicity violates the Occupational Safety and Health Administration regulations, an eco-friendly alternative would be the need of the hour. Hence an instant media which is economical and nontoxic and enables easy transport of biopsied soft tissue specimens in its original state is of vital importance. Materials and Methods. Commercially available fresh goat buccal mucosa specimens were sliced into smaller bits of equal dimensions and placed in six different containers containing 20% honey, 30% jaggery, milk, and ice for 1 hr, 6 hours, 12 hours, and 24 hours each with formalin as a positive control. After the set time interval, the specimens were fixed in 10% buffered formalin for 24 hours followed by routine processing and staining. The histologic interpretations were a blinded procedure and evaluated by two experts. Results were statistically analysed. Results. 30% jaggery proved to be an ideal transport media showing high quality preservation after 24 hours. 20% honey and ice showed optimal tissue preservation up to 6 hours following which quality deteriorated. Tissues transported in milk showed poor preservation. Conclusion. 30% jaggery can be endorsed in routine histopathological analysis as a transport media.

    Hand washing is the most effective way to prevent the spread of communicable disease. The purpose of this double-blind, placebo-controlled study was to assess whether an alcohol-free, instant hand sanitizer containing surfactants, allantoin, and benzalkonium chloride could reduce illness absenteeism in a population of 769 elementary school children and serve as an effective alternative when regular soap and water hand washing was not readily available. Prior to the study, students were educated about proper hand washing technique, the importance of hand washing to prevent transmission of germs, and the relationship between germs and illnesses. Children in kindergarten through the 6th grade (ages 5-12) were assigned to the active or placebo hand-sanitizer product and instructed to use the product at scheduled times during the day and as needed after coughing or sneezing. Data on illness absenteeism were tracked. After 5 weeks, students using the active product were 33% less likely to have been absent because of illness when compared with the placebo group.

    Nowadays, gold nanoparticles (AuNps) can be used in a variety of applications, thus efficient methods to produce them are necessary. Several methods have been proposed in this area, but NPs production time is one limitation of these approaches. In this study, we propose a high competitive method to synthesize gold colloidal nanoparticles, instantaneously, using no-toxic reducing agents. These substances allow the instantaneous synthesis at room temperature, even without magnetic stirrers, ovens or ultrasonic baths. Optic analysis showed two absorption bands, associated with surface Plasmon as function of HAuCl_4 concentration. The nanoparticles synthesized have a 10–20 nm size, seen by the transmission electron microscopy (TEM). Therefore, it was possible to obtain several geometric patterns of AuNps, and the synthesis was performed reducing significantly processing time. Additionally, Mie and Fuchs theories were used to predict the location of the absorption bands linked to the plasmon surface in gold nanoparticles. The Surface Enhanced Raman Spectroscopy (SERS) effect was analyzed considering natural zeolite (Chabazite) as analyte, in order to determinate its possible application in soil analysis. - Highlights: • Cubic and spherical morphologies in AuNp. • Surface plasmon prediction in cubic and spherical AuNp. • Instant synthesis of AuNp. • SERS applications in soil analysis.

    In the present study, initial microbial load of instant cup noodle (ICN) was investigated and gamma irradiation applied to develop immuno-compromised patients food for their safe consumption. The initial microbial population of dried vegetable and meat, and noodle was below the detection limit (1 log CFU/g); however, that of seasoning powder was just above 4 log CFU/g. Moreover, rehydrated-ICN with water at 100 °C still show above 3 log CFU/g of microbial load, which indicates the need for an additional process to control microbial safety of the seasoning powder. The total aerobic bacteria in seasoning powder and rehydrated-ICN could be controlled with 17 kGy gamma irradiation. This result referred 17 kGy gamma irradiation could reach 'practical sterility' of ICN. The overall difference in sensory properties between the non-irradiated and irradiated ICN was insignificant. Thus, gamma irradiation could improve the microbial quality of ICN, and reduce the risk of infection posed by the seasoning powder, without any adverse effects on their sensory quality. These results suggest that gamma-irradiated ICN can be used as a snack food for immuno-compromised patients.

    A Road Accident Prevention (RAP) scheme based on Vehicular Backbone Network (VBN) structure is proposed in this paper for Vehicular Ad-hoc Network (VANET). The RAP scheme attempts to prevent vehicles from highway road traffic accidents and thereby reduces death and injury rates. Once the possibility of an emergency situation (i.e. an accident) is predicted in advance, instantly RAP initiates a highway road traffic accident prevention scheme. The RAP scheme constitutes the following activities: (i) the Road Side Unit (RSU) constructs a Prediction Report (PR) based on the status of the vehicles and traffic in the highway roads, (ii) the RSU generates an Emergency Warning Message (EWM) based on an abnormal PR, (iii) the RSU forms a VBN structure and (iv) the RSU disseminates the EWM to the vehicles that holds the high Risk Factor (RF) and travels in High Risk Zone (HRZ). These vehicles might reside either within the RSU's coverage area or outside RSU's coverage area (reached using VBN structure). The RAP scheme improves the performance of EWM dissemination in terms of increase in notification and decrease in end-to-end delay. The RAP scheme also reduces infrastructure cost (number of RSUs) by formulating and deploying the VBN structure. The RAP scheme with VBN structure improves notification by 19 percent and end-to-end delay by 14.38 percent for a vehicle density of 160 vehicles. It is also proved from the simulation experiment that the performance of RAP scheme is promising in 4-lane highway roads.

    Mobile instant messaging (MIM) tools, such as WhatsApp, have transformed global communication practice. In the field of global health, MIM is an increasingly used, but little understood, phenomenon. It remains unclear how MIM can be used by rural community health workers (CHWs) and their facilitators, and what are the associated benefits and constraints. To address this gap, WhatsApp groups were implemented and researched in a rural setting in Malawi. The multi-site case study research triangulated interviews and focus groups of CHWs and facilitators with the thematic qualitative analysis of the actual conversations on WhatsApp. A survey with open questions and the quantitative analysis of WhatsApp conversations were used as supplementary triangulation sources. The use of MIM was differentiated according to instrumental (e.g. mobilising health resources) and participatory purposes (e.g. the enactment of emphatic ties). The identified benefits were centred on the enhanced ease and quality of communication of a geographically distributed health workforce, and the heightened connectedness of a professionally isolated health workforce. Alongside minor technical and connectivity issues, the main challenge for the CHWs was to negotiate divergent expectations regarding the social versus the instrumental use of the space. Despite some challenges and constraints, the implementation of WhatsApp was received positively by the CHWs and it was found to be a useful tool to support distributed rural health work.

  18. Visual Iconic Patterns of Instant Messaging: Steps Towards Understanding Visual Conversations

    Science.gov (United States)

    Bays, Hillary

    An Instant Messaging (IM) conversation is a dynamic communication register made up of text, images, animation and sound played out on a screen with potentially several parallel conversations and activities all within a physical environment. This article first examines how best to capture this unique gestalt using in situ recording techniques (video, screen capture, XML logs) which highlight the micro-phenomenal level of the exchange and the macro-social level of the interaction. Of particular interest are smileys first as cultural artifacts in CMC in general then as linguistic markers. A brief taxonomy of these markers is proposed in an attempt to clarify their frequency and patterns of their use. Then, focus is placed on their importance as perceptual cues which facilitate communication, while also serving as emotive and emphatic functional markers. We try to demonstrate that the use of smileys and animation is not arbitrary but an organized interactional and structured practice. Finally, we discuss how the study of visual markers in IM could inform the study of other visual conversation codes, such as sign languages, which also have co-produced, physical behavior, suggesting the possibility of a visual phonology.

    This exploratory research proposes the concept of instant messaging (IM) addiction and examines (a) whether IM addiction exists among Chinese teenagers and, if so, who the addicts are, what their symptoms are, and to what extent they are addicted; (b) whether psychological variables such as shyness and alienation can predict IM use or addiction among teenagers; and (c) whether IM use or IM addiction can impair the academic performance of teenagers. Using Young's classic definition of Internet addiction, results of a stratified random sample of 330 teenagers in China in 2007 found 95.8% of participants use IM, and 9.8% of them can be classified as IM addicts. Factor analysis identified four major IM addiction symptoms among teenagers: preoccupation with IM, loss of relationships due to overuse, loss of control, and escape. Results also showed that shyness and alienation from family, peers, and school are significantly and positively associated with levels of IM addiction. As expected, both the level of IM use and level of IM addiction are significantly linked to teenagers' academic performance decrement.

When REM was applied to instant fried noodles (1% and 2% by weight of wheat flour) for rutin fortification, the levels of rutin in the noodles were determined to be about 250-500mg/100g which corresponded to the recommended daily dose of rutin. While frying temperatures (150-190°C) and times (1-3min) did not negatively affect the level of rutin in the instant fried noodles, the distinct loss of rutin was observed after cooking. Furthermore, REM did not significantly affect the oil uptake and mechanical property of instant fried noodles. The strong antioxidant activity of rutin in REM contributed to retarding the oxidative deterioration of the noodles during storage. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Coffee is one of the most consumed beverages in the world, being a source of bioactive compounds as well as flavors. Hydroxycinnamic acids, flavonols, and carboxylic acids have been studied in the samples of instant coffee commercialized in Spain. The studies about contents of food components should be complemented with either in vitro or in vivo bioaccessibility studies to know the amount of food components effectively available for functions in the human body. In this sense, a widely used in vitro model has been applied to assess the potential intestinal absorption of phenolic compounds and organic acids. The contents of hydroxycinnamic acids and flavonols were higher in instant regular coffee samples than in the decaffeinated ones. Bioaccessible phenolic compounds in most analyzed samples account for 20-25% of hydroxycinnamic acids and 17-26% of flavonols. This could mean that a great part of them can remain in the gut, acting as potential in situ antioxidants. Quinic, acetic, pyroglutamic, citric and fumaric acids were identified in commercial instant coffee samples. Succinic acid was found in the coffee blend containing chicory. All carboxylic acids showed a very high bioaccessibility. Particularly, acetic acid and quinic acid were found in higher contents in the samples treated with the in vitro simulation of gastrointestinal processes, compared to the original ones, which can be explained by their cleavage from chlorogenic acid during digestion. This is considered as a positive effect, since quinic acid is considered as an antioxidant inducer.

    We investigated the impact of a customized alcohol-based instant hand sanitizer hand-hygiene regimen in an Army basic training setting. The entire population at the U.S. Army Field Artillery Training Center, Fort Sill, Oklahoma, participated in the 13-week prospective cohort study between January 18, 2005 and April 18, 2005. Two training battalions were randomly assigned to the control group, one to the primary intervention group (customized Purell Instant Hand Sanitizer regimen, education, reinforcement) and one to the secondary intervention group (customized Purell Instant Hand Sanitizer regimen). When compared to the control group, intervention groups experienced 40% less respiratory illness (p < 0.001), 48% less gastrointestinal illness (p < 0.02), 44% less lost training time (p < 0.001), and 31% fewer health care encounters (p < 0.001). These findings suggest that this intervention is capable of significantly reducing illness in this setting and has the potential to help reduce absenteeism in the military workforce as a whole.

    Full Text Available The objective of this study was to assess consumer acceptability, preference and consumption intent of an instant soy maize porridge, compared to an instant plain maize porridge, in order to determine the successful inclusion of the soy maize porridge as a food supplement for HIV subjects in a subsequent nutrition intervention trial, to improve their nutritional status. A 5-point hedonic and food action rating scale was used for this purpose. HIV-positive (n=57 and HIV-negative (n=47 subjects were recruited on a basis of availability and willingness to participate. Long-term acceptability and compliance of HIV-positive consumers (n=9 was assessed after three and five months. Analysis of variance (ANOVA, Tukey’s multiple comparison test and T-tests (p≤0.05 were performed. Overall, consumers found the soy maize porridge significantly more acceptable, preferred it to, and also intended to consume it more often than the plain maize porridge. There were no significant differences between the HIV-positive and HIV-negative group regarding acceptability, preference and consumption intent. After three and five months, the HIV-positive consumers (n=9 did not find acceptability of the soy maize porridge significantly different from the first evaluation. It therefore had the potential to be included successfully in the nutrition intervention trial. The current study emphasises the need for sensory evaluation of food products prior to including them in intervention studies, to assess consumers’ acceptance of them.

    The current study investigated the levels of some heavy metals [lead (Pb), arsenic (As), nickel (Ni), mercury (Hg), copper (Cu), cadmium (Cd), aluminum (Al), and chromium (Cr)] and polycyclic aromatic hydrocarbons (PAHs) in six brands of instant noodles (CFN, GFC, NGP, GAA, CUN, and FCS) commonly consumed in Port Harcourt, Nigeria. Risks of consumption of contaminated noodles were also assessed. Heavy metal content and PAHs were determined using flame atomic absorption spectrophotometer and gas chromatography, respectively. Concentrations of heavy metals as Pb, Ni, Cu, Al, and Cr were detected while As, Hg, and Cd were not detected in noodles. High average concentrations (mean ± SD mg/kg) of Pb were observed in brands CFN (3.163 ± 0.21) and GFC (1.022 ± 0.08) which were significantly higher (P ≤ 0.05) than in NGP (0.043 ± 0.15) and GAA (0.276 ± 0.18), although all were above WHO permissible limits (0.025 mg/kg). Target Hazard Quotient and Hazard Index for Pb were > 1 in brands CFN and GFC indicating unacceptable risk. Results of PAHs showed brands had total PAHs (mg/kg) in the order CFN > CUN > GAA > NGP > FCS > GFC. Although carcinogenic risks associated with these noodles are within permissible range, consumption of CFN and GFC could pose greater health risk to consumers. Long-term consumption of brands CUN, CFN, and GAA may have higher probability of carcinogenesis among consumers. We therefore recommend more diligent regulatory policies and monitoring by relevant government agencies (WHO, NAFDAC, CPC, and SON) to ensure wholesome noodles get to consumers.

  13. Decoding Delay Controlled Completion Time Reduction in Instantly Decodable Network Coding

    2016-06-27

    For several years, the completion time and the decoding delay problems in Instantly Decodable Network Coding (IDNC) were considered separately and were thought to act completely against each other. Recently, some works aimed to balance the effects of these two important IDNC metrics but none of them studied a further optimization of one by controlling the other. This paper investigates the effect of controlling the decoding delay to reduce the completion time below its currently best-known solution in both perfect and imperfect feedback with persistent erasure channels. To solve the problem, the decodingdelay- dependent expressions of the users’ and overall completion times are derived in the complete feedback scenario. Although using such expressions to find the optimal overall completion time is NP-hard, the paper proposes two novel heuristics that minimizes the probability of increasing the maximum of these decoding-delay-dependent completion time expressions after each transmission through a layered control of their decoding delays. Afterward, the paper extends the study to the imperfect feedback scenario in which uncertainties at the sender affects its ability to anticipate accurately the decoding delay increase at each user. The paper formulates the problem in such environment and derives the expression of the minimum increase in the completion time. Simulation results show the performance of the proposed solutions and suggest that both heuristics achieves a lower mean completion time as compared to the best-known heuristics for the completion time reduction in perfect and imperfect feedback. The gap in performance becomes more significant as the erasure of the channel increases.

    The presence of the carbon dots (C-dots) in food is a hotly debated topic and our knowledge about the presence and the use of carbon dots (C-dots) in food is still in its infancy. We report the finding of the presence of photoluminescent (PL) C-dots in commercial Nescafe instant coffee. TEM analysis reveals that the extracted C-dots have an average size of 4.4 nm. They were well-dispersed in water and strongly photoluminescent under the excitation of ultra-violet light with a quantum yield (QY) about 5.5%, which were also found to possess clear upconversion PL properties. X-ray photoelectron spectroscopy characterization demonstrates that the C-dots contain C, O and N three elements with the relative contents ca. 30.1, 62.2 and 7.8%. The X-ray diffraction (XRD) analysis indicates that the C-dots are amorphous. Fourier-transform infrared (FTIR) spectra were employed to characterize the surface groups of the C-dots. The C-dots show a pH independent behavior by varying the pH value from 2 to 11. The cytotoxicity study revealed that the C-dots did not cause any toxicity to cells at a concentration as high as 20 mg/mL. The C-dots have been directly applied in cells and fish imaging, which suggested that the C-dots present in commercial coffee may have more potential biological applications. Copyright © 2014.

    Objective Instant (scratch) lottery ticket gambling is popular among adolescents. Prior research has not determined whether adolescents’ gambling behavior and attitudes toward gambling are influenced by the receipt of scratch lottery tickets as gifts. Method Cross-sectional survey data from 2,002 Connecticut high school students with past-year gambling were analyzed using bivariate approaches and logistic regression analyses. Interactions between gambling-problem severity and lottery-gift status were examined in relation to multiple outcomes. Results Adolescents who received a scratch lottery ticket as a gift compared with those who did not were more likely to report features of problem gambling, buy scratch lottery tickets for themselves, and buy and receive other types of lottery tickets; they were also less likely to report parental disapproval of gambling and to see gambling prevention efforts as important. Later (≥15 years) age-at-gambling-onset was inversely linked to gambling-problem severity in the lottery gift group (odds ratio [OR] = .38) but not in the nongift group (OR = .91), yielding a significant severity by gift status interaction. Other academic, health, and gambling-related correlates of gambling-problem severity were similar in the gift and nongift groups. Conclusions For adolescents, the receipt of scratch lottery tickets as gifts during childhood or adolescence was associated with risky/problematic gambling and with gambling-related attitudes, behaviors, and views suggesting greater gambling acceptability. The extent to which the receipt of scratch lottery tickets may promote gambling behaviors and the development of gambling problems warrants consideration. Education, prevention, and treatment strategies should incorporate findings relating to receipt of gambling products by underage individuals. PMID:23299004

    The frequent use of plant-based products to promote health leads to the search for scientific information related to efficacy and safety of those products for human consumption. Two alfalfa-derived products (ADP), freeze-dried juice (FDJ) and dehydrated powder (DP), from alfalfa harvested in Mexico, are being developed as new possible nutraceuticals. To the best of our knowledge, any study reports the real composition of such products used to prepare instant beverages in what concerns isoflavone contents. Seven isoflavones (glycitein, formononetin, biochanin A, daidzein, genistein, daidzin and genistin) were assessed by HPLC-DAD analysis as well as its variation in five different batches of these products. Different solvents were tested in order to choose the best one to extract isoflavones. The results showed the presence of daidzein, genistein, genistin and daidzin in most samples while glycitein, formononetin and biochanin A were not detected. Significant differences between isoflavone contents were found with different solvent systems. Water was the best option to extract daidzein (0.40-1.08 mg per unit and 1.30-4.90 mg per unit for DP and FDJ, respectively) whereas the water-methanol-formic acid mixture was efficient to extract genistein (0.19-0.43 mg per unit and 0.15-0.72 mg per unit for DP and FDJ, respectively). In all cases, the total isoflavone content was higher in freeze-dried juices than in dehydrated powders. Genistein and daidzein were the more abundant isoflavones quantified. Further physiological and nutritional studies are needed to complete the validation of effectiveness and safety of these products.

    Full Text Available A Road Accident Prevention (RAP scheme based on Vehicular Backbone Network (VBN structure is proposed in this paper for Vehicular Ad-hoc Network (VANET. The RAP scheme attempts to prevent vehicles from highway road traffic accidents and thereby reduces death and injury rates. Once the possibility of an emergency situation (i.e. an accident is predicted in advance, instantly RAP initiates a highway road traffic accident prevention scheme. The RAP scheme constitutes the following activities: (i the Road Side Unit (RSU constructs a Prediction Report (PR based on the status of the vehicles and traffic in the highway roads, (ii the RSU generates an Emergency Warning Message (EWM based on an abnormal PR, (iii the RSU forms a VBN structure and (iv the RSU disseminates the EWM to the vehicles that holds the high Risk Factor (RF and travels in High Risk Zone (HRZ. These vehicles might reside either within the RSU's coverage area or outside RSU's coverage area (reached using VBN structure. The RAP scheme improves the performance of EWM dissemination in terms of increase in notification and decrease in end-to-end delay. The RAP scheme also reduces infrastructure cost (number of RSUs by formulating and deploying the VBN structure. The RAP scheme with VBN structure improves notification by 19 percent and end-to-end delay by 14.38 percent for a vehicle density of 160 vehicles. It is also proved from the simulation experiment that the performance of RAP scheme is promising in 4-lane highway roads.

    The impact of burn-up on the instant release fraction (IRF) from spent fuel was studied using very high burn-up UO{sub 2} fuel (∝ 100 GWd/t) from a prototype high temperature reactor (HTR). TRISO (TRi-structural-ISO-tropic) particles from the spherical fuel elements contain UO{sub 2} fuel kernels (500 μm diameter) which are coated by three tight layers ensuring the encapsulation of fission products during reactor operation. After cracking of the tight coatings {sup 85}Kr and {sup 14}C as {sup 14}CO{sub 2} were detected in the gas fraction. Xe was not detected in the gas fraction, although ESEM (Environmental Scanning Electron Microscope) investigations revealed an accumulation in the buffer. UO{sub 2} fuel kernels were exposed to synthetic groundwater under oxic and anoxic/reducing conditions. U concentration in the leachate was below the detection limit, indicating an extremely low matrix dissolution. Within the leach period of 276 d {sup 90}Sr and {sup 134/137}Cs fractions located at grain boundaries were released and contribution to IRF up to max. 0.2% respectively 8%. Depending on the environmental conditions, different release functions were observed. Second relevant release steps occurred in air after ∝ 120 d, indicating the formation of new accessible leaching sites. ESEM investigations were performed to study the impact of leaching on the microstructure. In oxic environment, numerous intragranular open pores acting as new accessible leaching sites were formed and white spherical spots containing Mo and Zr were identified. Under anoxic/reducing conditions numerous metallic precipitates (Mo, Tc and Ru) filling the intragranular pores and white spherical spots containing Mo and Zr, were detected. In conclusion, leaching in different geochemical environments influenced the speciation of radionuclides and in consequence the stability of neoformed phases, which has an impact on IRF.

    Instant power is a key parameter of the ITER. Its monitoring with an accuracy of a few percent is an urgent and challenging aspect of neutron diagnostics. In a series of works published in Problems of Atomic Science and Technology, Series: Thermonuclear Fusion under a common title, the step-by-step neutronics analysis was given to substantiate a calibration technique for the DT and DD modes of the ITER. A Gauss quadrature scheme, optimal for processing "expensive" experiments, is used for numerical integration of 235U and 238U detector responses to the point sources of 14-MeV neutrons. This approach allows controlling the integration accuracy in relation to the number of coordinate mesh points and thus minimizing the number of irradiations at the given uncertainty of the full monitor response. In the previous works, responses of the divertor and blanket monitors to the isotropic point sources of DT and DD neutrons in the plasma profile and to the models of real sources were calculated within the ITER model using the MCNP code. The neutronics analyses have allowed formulating the basic principles of calibration that are optimal for having the maximum accuracy at the minimum duration of in situ experiments at the reactor. In this work, scenarios of the preliminary and basic experimental ITER runs are suggested on the basis of those principles. It is proposed to calibrate the monitors only with DT neutrons and use correction factors to the DT mode calibration for the DD mode. It is reasonable to perform full calibration only with 235U chambers and calibrate 238U chambers by responses of the 235U chambers during reactor operation (cross-calibration). The divertor monitor can be calibrated using both direct measurement of responses at the Gauss positions of a point source and simplified techniques based on the concepts of equivalent ring sources and inverse response distributions, which will considerably reduce the amount of measurements. It is shown that the monitor

    Anemia is a significant public health problem among schoolchildren in Vietnam. Food fortification is considered one of the most sustainable long-term strategies to control iron-deficiency anemia in Vietnam. The success of a food-fortification program depends on the choice of the food vehicle. The aim of the present study was to identify an appropriate vehicle for iron fortification to be used in a school-feeding program aimed at improving the iron and anemia status of schoolchildren in rural Vietnam. Children 6 to 8 years of age in two primary schools in Tam Nong District, Phu Tho Province, and their parents were included in this study. The study consisted of three substudies: a food-consumption study with 24-hour recalls of two nonconsecutive days; a food-beliefs study, with focus group discussions, a pile-sorting test, and a food attributes and differences exercise; and a food-acceptance study using noodles and biscuits fortified with sodium iron ethylenediaminetetraacetic acid (NaFeEDTA). The average number of meals consumed daily was 3.2 +/- 0.4, and the average intakes of energy and iron were 1,218 +/- 406 kcal and 7.5 +/- 4.0 mg, respectively. Compared with biscuits and instant rice soup, instant noodles were consumed more frequently and in larger portion sizes and are more acceptable as children's food in the culture of the local people. The iron level of the fortified product did not affect the mean consumption of noodles, but a higher level of iron was associated with a lower mean consumption of biscuits (p noodles; however, during preparation at least 70% of the iron is leaked into the soup. Instant noodles are a suitable vehicle for iron fortification for use in school-based intervention to improve iron-deficiency anemia among primary schoolchildren in rural Vietnam.

    Smartphones have the ability to capture and send images, and their use has become common in the emergency setting for transmitting radiographic images with the intent to consult an off-site specialist. Our objective was to evaluate the reliability of smartphone-based instant messaging applications for the evaluation of various pediatric limb traumas, as compared with the standard method of viewing images of a workstation-based picture archiving and communication system (PACS). X-ray images of 73 representative cases of pediatric limb trauma were captured and transmitted to 5 pediatric orthopedic surgeons by the Whatsapp instant messaging application on an iPhone 6 smartphone. Evaluators were asked to diagnose, classify, and determine the course of treatment for each case over their personal smartphones. Following a 4-week interval, revaluation was conducted using the PACS. Intraobserver agreement was calculated for overall agreement and per fracture site. The overall results indicate "near perfect agreement" between interpretations of the radiographs on smartphones compared with computer-based PACS, with κ of 0.84, 0.82, and 0.89 for diagnosis, classification, and treatment planning, respectively. Looking at the results per fracture site, we also found substantial to near perfect agreement. Smartphone-based instant messaging applications are reliable for evaluation of a wide range of pediatric limb fractures. This method of obtaining an expert opinion from the off-site specialist is immediately accessible and inexpensive, making smartphones a powerful tool for doctors in the emergency department, primary care clinics, or remote medical centers, enabling timely and appropriate treatment for the injured child. This method is not a substitution for evaluation of the images in the standard method over computer-based PACS, which should be performed before final decision-making.

    To use a promising analytical method, namely intersubject synchronisation (ISS), to evaluate the brain activity associated with the instant effects of acupuncture and compare the findings with traditional general linear model (GLM) methods. 30 healthy volunteers were recruited for this study. Block-designed manual acupuncture stimuli were delivered at SP6, and de qi sensations were measured after acupuncture stimulation. All subjects underwent functional MRI (fMRI) scanning during the acupuncture stimuli. The fMRI data were separately analysed by ISS and traditional GLM methods. All subjects experienced de qi sensations. ISS analysis showed that the regions activated during acupuncture stimulation at SP6 were mainly divided into five clusters based on the time courses. The time courses of clusters 1 and 2 were in line with the acupuncture stimulation pattern, and the active regions were mainly involved in the sensorimotor system and salience network. Clusters 3, 4 and 5 displayed an almost contrary time course relative to the stimulation pattern. The brain regions activated included the default mode network, descending pain modulation pathway and visual cortices. GLM analysis indicated that the brain responses associated with the instant effects of acupuncture were largely implicated in sensory and motor processing and sensory integration. The ISS analysis considered the sustained effect of acupuncture and uncovered additional information not shown by GLM analysis. We suggest that ISS may be a suitable approach to investigate the brain responses associated with the instant effects of acupuncture. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Provider-patient communication is an important factor influencing patients' satisfaction and health outcomes. This study draws upon the uses and gratification theory to examine how individuals' perception of communication with healthcare providers is associated with their Internet use for health-related activities. Using the data from the 2007 Health Information National Trends Survey (HINTS), we found that as individuals perceived their communication with providers to be less patient-centered, they were more likely to engage in various types of online health activities, such as using websites for healthy lifestyles, searching for healthcare providers, and seeking health information. Trust in online health information was also found to be a significant predictor of online health activities. The results of this study emphasized the important role of provider-patient communication in motivating individuals to turn to the Internet for health purposes.

    Computer vision-based image analysis systems are widely used in food processing to evaluate quality changes. They are able to objectively measure the surface colour of various products since, providing some obvious advantages with their objectivity and quantitative capabilities. In this study, a computer vision-based image analysis system was used to investigate the colour changes of apple slices dried by instant controlled pressure drop-assisted hot air drying (AD-DIC). The CIE L* value and polyphenol oxidase activity in apple slices decreased during the entire drying process, whereas other colour indexes, including CIE a*, b*, ΔE and C* values, increased. The browning ratio calculated by image analysis increased during the drying process, and a sharp increment was observed for the DIC process. The change in 5-hydroxymethylfurfural (5-HMF) and fluorescent compounds (FIC) showed the same trend with browning ratio due to Maillard reaction. Moreover, the concentrations of 5-HMF and FIC both had a good quadratic correlation (R 2  > 0.998) with the browning ratio. Browning ratio was a reliable indicator of 5-HMF and FIC changes in apple slices during drying. The image analysis system could be used to monitor colour changes, 5-HMF and FIC in dehydrated apple slices during the AD-DIC process. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Global prevalence of non-alcoholic fatty liver disease (NAFLD) constitutes a threat to human health. Goose is a unique model of NAFLD for discovering therapeutic targets as its liver can develop severe steatosis without overt injury. Fatty acid desaturase (Fads) is a potential therapeutic target as Fads expression and mutations are associated with liver fat. Here, we hypothesized that Fads was promoted to provide a protection for goose fatty liver. To test this, goose Fads1 and Fads2 were sequenced. Fads1/2/6 expression was determined in goose liver and primary hepatocytes by quantitative PCR. Liver fatty acid composition was also analyzed by gas chromatography. Data indicated that hepatic Fads1/2/6 expression was gradually increased with the time of overfeeding. In contrast, trans-C18:1n9 fatty acid (Fads inhibitor) was reduced. However, enhanced Fads capacity for long-chain polyunsaturated fatty acid (LC-PUFA) synthesis was not sufficient to compensate for the depleted LC-PUFAs in goose fatty liver. Moreover, cell studies showed that Fads1/2/6 expression was regulated by fatty liver-associated factors. Together, these findings suggest Fads1/2 as protective components are promoted to meet instant need for LC-PUFAs in goose fatty liver, and we propose this is required for severe hepatic steatosis without liver injury.

    Instant sea cucumber has become one popular product due to its convenience to eat, favourable taste and minimal loss of nutrients and bioactive components. However, there was rare information about the water dynamic of instant sea cucumber subjected to multiple freeze-thaw cycles. In this study, low-field nuclear magnetic resonance (LF-NMR) and magnetic resonance image (MRI) were employed to investigate the effect of freeze-thaw cycles on water status of instant sea cucumber. Four water populations corresponding to strongly bound water, weakly bound water, immobile water and free water were observed in instant sea cucumber. With the increase of freeze-thaw cycles, the transverse relaxation time of immobile and free water increased, while the peak area of free water decreased significantly. MRI enabled the visualization of water migration of instant sea cucumber during multiple freeze-thaw cycles. Multiple freeze-thaw cycles also led to significant changes of other quality properties including thawing loss, WHC, color parameters, texture and protein content, and enlarge the interspace between fiber network in microstructure. Good correlations between T 22 , A 22 , A 23 and thaw loss, WHC, L*, hardness and collagen content (0.873 ≤ r ≤ 0.958) revealed LF-NMR may be an effective real-time monitoring method of these physicochemical parameters as a non-destructive technique.

    Theabrownins (TB) are bioactive components that are usually extracted from Chinese dark tea, in which they are present at low concentrations. The present study aimed to produce an instant dark tea high in theabrownins via submerged fermentation by the fungus Aspergillus niger. Three fermentation parameters that affect theabrownins content (i.e. inoculum size, liquid-solid ratio and rotation speed) were optimized using response surface methodology. Optimum fermentation conditions were modeled to be an inoculum of 5.40% (v/v), a liquid-solid ratio of 27.45 mL g -1 and a rotation speed of 184 rpm and were predicted to yield 292.99 g kg -1 TB. Under these experimentally conditions, the TB content of the instant dark tea was 291.93 g kg -1 . The antioxidant capacity and α-glucosidase and pancreatic lipase inhibitory activities of the high-TB instant black tea were higher than four other typical instant dark tea products. The results of the present study show that careful management of culture conditions can produce a dark tea high in theabrownins. Furthermore, high-theabrownins instant dark tea could serve as a source of bioactive products and be used in functional foods as an ingredient imparting antioxidant properties and the ability to inhibit pancreatic lipase and α-glucosidase. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    99 Tc m -labelled monoclonal antibodies (MAbs) and human immunoglobulins (hIgG) have recently emerged as a new class of site specific radiopharmaceuticals. The role of 99 Tc m -labelled MAbs particularly anti-CEA IgG in tumour imaging has essentially established for early revealing of occult lesions in patients. Superiority of the method over X ray CT has been addressed for its capability in differentiating post-operation fibrosis from viable tumour. At present data, instant kits for preparation of this particular class of radiopharmaceuticals can be obtained from commercial sources but unfortunately at high prices. This prohibits the use of these promising diagnostic agents in developing country like Thailand. Under the assistance from IAEA through a research coordinating program, we worked on the 99 Tc m -radiochemistry in immunoglobulin labelling to establish the knowledge and acquire the know how in the development of in-house instant kits at low cost to serve the local nuclear medicine clinics in diagnosis of infectious and neoplastic diseases

    Dentin hypersensitivity is sharp and unpleasant pains caused by exposed dentinal tubules when enamel outside of the tooth wears away. The occlusion of dentinal tubules via in situ remineralization of hydroxyapatite is the best method to alleviate the symptoms caused by dentin hypersensitivity. Commercially available dental desensitizers are generally effective only on a specific area and are relatively toxic, and their performance usually depends on the skill of the clinician. Here, a facile and efficient dentin hypersensitivity treatment with remarkable aesthetic improvement inspired by the tunicate-self-healing process is reported. As pyrogallol groups in tunicate proteins conjugate with metal ions to heal the torn body armor of a tunicate, the ingenious mechanism by introducing gallic acid (GA) as a cheap, abundant, and edible alternative to the pyrogallol groups of the tunicate combined with a varied daily intake of metal ion sources is mimicked. In particular, the GA/Fe(3+) complex exhibits the most promising results, to the instant ≈52% blockage in tubules within 4 min and ≈87% after 7 d of immersion in artificial saliva. Overall, the GA/metal ion complex-mediated coating is facile, instant, and effective, and is suggested as an aesthetic solution for treating dentin hypersensitivity. © 2016 WILEY-VCH Verlag GmbH & Co.
