    Full Text Available Core part of state-of-the-art mobile networks is composed of several standard elements like GGSN (Gateway General Packet Radio Service Support Node, SGSN (Serving GPRS Support Node, F5 or MSP (Multi Service Proxy. Each node handles network traffic from a slightly different perspective, and with various goals. In this article we will focus only on the MSP, its key features and especially on related security issues. MSP handles all HTTP traffic in the mobile network and therefore it is a suitable point for the implementation of different optimization functions, e.g. to reduce the volume of data generated by YouTube or similar HTTP-based service. This article will introduce basic features and functions of MSP as well as ways of remote access and security mechanisms of this key element in state-of-the-art mobile networks.

  3. Academic entitlement in pharmacy education.

    Cain, Jeff; Romanelli, Frank; Smith, Kelly M

    2012-12-12

    The constructs of academic entitlement and student consumerism refer to students' attitudes toward education as a commodity and the underlying belief that as consumers, they should be catered to and given the opportunity to participate in the education process according to their preferences. Most discussions regarding these attitudes are anecdotal, but the pervasiveness of these accounts and the troubling effects that ensue warrant attention. Grade inflation, student incivility, altered classroom practices, and decreased faculty morale are all potential aftereffects of teaching students who hold academic entitlement beliefs. Numerous factors are posited as attributing to academic entitlement including personal issues, societal pressures, and broad academic practices. This paper discusses these factors and offers faculty members and administrators recommendations regarding practices that may curb or alleviate issues associated with academically entitled students.

  6. Identifying Two Groups of Entitled Individuals: Cluster Analysis Reveals Emotional Stability and Self-Esteem Distinction.

    Crowe, Michael L; LoPilato, Alexander C; Campbell, W Keith; Miller, Joshua D

    2016-12-01

    The present study hypothesized that there exist two distinct groups of entitled individuals: grandiose-entitled, and vulnerable-entitled. Self-report scores of entitlement were collected for 916 individuals using an online platform. Model-based cluster analyses were conducted on the individuals with scores one standard deviation above mean (n = 159) using the five-factor model dimensions as clustering variables. The results support the existence of two groups of entitled individuals categorized as emotionally stable and emotionally vulnerable. The emotionally stable cluster reported emotional stability, high self-esteem, more positive affect, and antisocial behavior. The emotionally vulnerable cluster reported low self-esteem and high levels of neuroticism, disinhibition, conventionality, psychopathy, negative affect, childhood abuse, intrusive parenting, and attachment difficulties. Compared to the control group, both clusters reported being more antagonistic, extraverted, Machiavellian, and narcissistic. These results suggest important differences are missed when simply examining the linear relationships between entitlement and various aspects of its nomological network.

    Full Text Available Há pelo menos dois registros diferentes sobre o significado de “direitos”. Segundo um deles, os direitos são relações entre dois termos: uma pessoa e um bem; para o outro, os direitos são relações entre três termos: um indivíduo, uma pessoa e uma ação ou algo. Os registros são diferentes, mas não são totalmente incompatíveis. De acordo com a interpretação de direitos como entitlements, trata-se de direitos morais ou legais, ou seja, as relações de ordem moral ou jurídica das pessoas com bens (de benefícios concedidos a pessoas por uma lei humana, moral ou legal. Como uma espécie de direitos, os direitos humanos são vistos como direitos (entitlements das pessoas ou dos indivíduos a bens essenciais, dos quais podem-se inferir reivindicações (claims contra outras pessoas ou contra governos e representantes.

    2014-08-15

    To determine a measurable definition of academic entitlement, measure academic entitlement in graduating doctor of pharmacy (PharmD) students, and compare the academic performance between students identified as more or less academically entitled. Graduating students at a private health sciences institution were asked to complete an electronic survey instrument that included demographic data, academic performance, and 2 validated academic entitlement instruments. One hundred forty-one of 243 students completed the survey instrument. Fourteen (10%) students scored greater than the median total points possible on 1 or both of the academic entitlement instruments and were categorized as more academically entitled. Less academically entitled students required fewer reassessments and less remediation than more academically entitled students. The highest scoring academic entitlement items related to student perception of what professors should do for them. Graduating pharmacy students with lower levels of academic entitlement were more academically successful than more academically entitled students. Moving from an expert opinion approach to evidence-based decision-making in the area of academic entitlement will allow pharmacy educators to identify interventions that will decrease academic entitlement and increase academic success in pharmacy students.

  16. Entitlement and organizational behaviors: the moderating role of narcissism

    Directory of Open Access Journals (Sweden)

    Agata Szalkowska

    2015-10-01

    Full Text Available Background The purpose of this study was to investigate the relationship between psychological entitlement (active, passive, and revenge, narcissism and two types of organizational behaviors in employees. Interactions between narcissism and psychological entitlement as predictors of organizational citizenship behaviors (OCB and counterproductive work behaviors (CWB were explored. Predictors were analyzed in an effort to determine whether psychological entitlement plays a more destructive role among narcissistic employees than among non-narcissistic ones and whether the effects of narcissism on OCB and CWB are mediated by entitlement. Participants and procedure Data were obtained from 100 employees (34% men aged 22 to 59 years (M = 37.00, SD = 9.30 from public and private companies. Participants were asked to complete the Organizational Citizenship Behavior Scale (OCBS, the Counterproductive Organizational Behaviors Scale (COBS, the Entitlement Questionnaire, and the Narcissistic Personality Inventory (NPI. Results Positive aspects of entitlement were positively associated with OCB only among narcissistic employees, and active entitlement mediated the effects of narcissism on CWB. Active entitlement was negatively related to CWB. Negative aspects of entitlement were negatively related to OCB and unrelated to CWB. Conclusions This study provides evidence for positive (healthy aspects of entitlement for organizations. The unexpected interaction between narcissism and entitlement in predicting higher levels of OCB suggests that among narcissistic employees, healthy aspects of entitlement are desirable and profitable for an organization. Psychological entitlement was observed to be an important predictor of organizational behaviors beyond narcissism itself.

  4. Can a sense of entitlement increase stealing?

    DEFF Research Database (Denmark)

    Gravert, Christina Annette

    was asked to roll a die to determine their payoff, while the other group had three minutes to find matching numbers in a matrix task. Participants then paid themselves unobserved by the experimenter. I find that the participants who earned their payoff according to performance were three times more likely...... to take the (undeserved) maximum payoff than the participants in the random payment scheme. In contrast to previous findings in the cheating literature, stealing is an all-or-nothing decision rather than a trade-off between a slightly higher payoff and the desire to keep ones moral values intact....... The results support the theory that unethical behavior is increased by a sense of entitlement, which is more pronounced when wealth depends on performance than on the roll of a die....

  12. Entitlement Management: Ready to Enter the IdM Mainstream

    Science.gov (United States)

    Gebel, Gerry; Wang, Alice

    Externalizing authorization processing from business applications has been a goal for architects and developers for many years. Recent compliance demands for more granular access control and policy transparency have increased the urgency to adopt an architectural model where authorization and entitlement management are consumed as a service rather than embedded within business applications. Major software vendors, such as Microsoft, Oracle, and SAP, are making significant steps to separate IdM functionality, including entitlement management from application logic. The market has also responded with a plethora of products that provide entitlement management and authorization functionality for commercial or custom-built application environments. Finally, the Extensible Access Control Markup Language (XACML) has emerged as the consensus authorization standard being supported by a growing number of IT and application vendors. Collectively, these forces form the basis of a nascent IdM market segment referred to as entitlement management.

    2013-01-01

    The current study explored whether earned entitlement modulated the perception of fairness in three experiments. A preliminary resource earning task was added before players decided how to allocate the resource they jointly earned. Participants' decision in allocation, their responses to equal or unequal offers, whether advantageous or disadvantageous, and subjective ratings of fairness were all assessed in the current study. Behavioral results revealed that participants proposed more generous offers and showed enhanced tolerance to disadvantageous unequal offers from others when they performed worse than their presumed "partners," while the reverse was true in the better-performance condition. The subjective ratings also indicated the effect of earned entitlement, such that worse performance was associated with higher perceived feelings of fairness for disadvantageous unequal offers, while better performance was associated with higher feelings of fairness for advantageous unequal offers. Equal offers were considered "fair" only when earned entitlement was even between two parties. In sum, the perception of fairness is modulated by an integration of egalitarian motivation and entitlement. In addition to justice principles, participants were also motivated by self-interest, such that participants placed more weight on entitlement in the better-performance condition than in the worse-performance condition. These results imply that earned entitlement is evaluated in a self-serving way.

  7. Parent training in nonviolent resistance for adult entitled dependence.

    2012-03-01

    "Adult entitled dependence" is a condition characterized by the extreme dependence of grown children on their family and by levels of dysfunction, seemingly excessive in light of their apparent capacity to function. The family and the dependent adult become involved in an interaction in which the very attempts to alleviate the problem may aggravate it. Parent-training in nonviolent resistance (NVR) is an intervention that has been shown to be helpful to parents of behaviorally disturbed youth. Parent training in NVR offers parents means to shift away from a stance of helplessness toward realistic goals that are accomplishable without the collaboration of their offspring. We report on the parents of 27 entitled dependent grown children who participated in parent training in NVR. Additionally, we present 2 detailed case studies that exemplify the problem and the therapeutic process. Before treatment, the dependent adults were not working or studying, drew heavily on parental services (financial or otherwise), and were resistant to parental attempts to change the situation. Most parents succeeded in overcoming their helplessness and reducing the provision of parental services. In a considerable proportion of cases, the grown children started working or studying or moved to independent lodgings. © FPI, Inc.

  9. Entitled to Addiction?: Pharmaceuticals, Race, and America's First Drug War.

    Science.gov (United States)

    Herzberg, David

    2017-01-01

    This article rethinks the formative decades of American drug wars through a social history of addiction to pharmaceutical narcotics, sedatives, and stimulants in the first half of the twentieth century. It argues, first, that addiction to pharmaceutical drugs is no recent aberration; it has historically been more extensive than "street" or illicit drug use. Second, it argues that access to psychoactive pharmaceuticals was a problematic social entitlement constructed as distinctively medical amid the racialized reforms of the Progressive Era. The resulting drug control regime provided inadequate consumer protection for some (through the FDA), and overly punitive policing for others (through the FBN). Instead of seeing these as two separate stories-one a liberal triumph and the other a repressive scourge-both should be understood as part of the broader establishment of a consumer market for drugs segregated by class and race like other consumer markets developed in the era of Progressivism and Jim Crow.

  10. Trait entitlement: A cognitive-personality source of vulnerability to psychological distress.

    Science.gov (United States)

    Grubbs, Joshua B; Exline, Julie J

    2016-11-01

    Psychological entitlement is a personality trait characterized by pervasive feelings of deservingness, specialness, and exaggerated expectations. The present review expands upon this understanding by conceptualizing entitlement as a cognitive-personality vulnerability to psychological distress. A review of research is conducted, and a novel, multipart model is described by which entitlement may be seen as such a vulnerability. First, exaggerated expectations, notions of the self as special, and inflated deservingness associated with trait entitlement present the individual with a continual vulnerability to unmet expectations. Second, entitled individuals are likely to interpret these unmet expectations in ways that foster disappointment, ego threat, and a sense of perceived injustice, all of which may lead to psychological distress indicators such as dissatisfaction across multiple life domains, anger, and generally volatile emotional responses. Furthermore, in the wake of disappointment, ego threat, or perceived injustice, entitled individuals are likely to attempt to bolster their entitled self-concept, leading to a reinforcement of entitled beliefs, thereby initiating the cycle again. At each stage of this process, entitlement presents the individual with the possibility of experiencing distress, predisposes further risk factors for distress (e.g., the subsequent steps in the model), and increases the risk of interpersonal conflict, again leading to distress. A review of relevant empirical data suggests preliminary support for this conceptual model of entitlement. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  11. Original article Entitlement and subjective well-being: a three-nations study

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Background The current study investigated the role of three facets of entitlement (active, passive and revenge in various forms of subjective well-being (SWB: hedonistic and two facets of eudaimonic well-being (social and psychological. Social well-being was based on Keyes’ model (1998 and psychological well-being on Ryff’s model (1989. Participants and procedure The study was performed in three nations (Poland, Puerto Rico and Vietnam on student samples (Poland, n = 245, Vietnam, n = 115, and Puerto Rico, n = 300. To assess entitlement level the Entitlement Questionnaire was used. The level of hedonistic well-being was measured with the Satisfaction with Life Scale (SWLS and the Positive and Negative Affect Schedule (PANAS, and eudaimonic well-being by the Mental Health Continuum–Short Form (MHC-SF. Results Active entitlement was positively related to all aspects of SWB. Revenge entitlement was negatively related to hedonistic and psychological SWB in all samples and negatively related to social well-being only in Poland. Passive entitlement was unrelated to SWB. Conclusions The current study shows cross-cultural similarities in relationships of entitlement with hedonistic and psychological well-being and cross-cultural differences in the relationship of entitlement with social well-being. Additionally, the study indicates positive meaning of healthy aspects of entitlement for subjective well-being and negative meaning of dysfunctional aspects of entitlement for subjective well-being.

  2. Permissive parenting and mental health in college students: Mediating effects of academic entitlement.

    Science.gov (United States)

    Barton, Alison L; Hirsch, Jameson K

    2016-01-01

    Student mental health may suffer due to unreasonable expectations associated with academic entitlement; permissive parenting may be one source of these expectations. The authors examined the role of academic entitlement as a mediator of the relationship between permissive parenting and psychological functioning. Participants were 524 undergraduate students at a single institution (52% female; age range = 18-22). Data collection was completed in May 2011. Cross-sectional design. Participants completed online self-report measures of parenting styles, academic entitlement, stress, depressive symptoms, and well-being. Permissive parenting was associated with greater academic entitlement and, in turn, to more perceived stress and poorer mental health. Mother/father differences were found in some cases. Academic entitlement may partially explain why permissive parenting is detrimentally related to mental health for college students. Implications for academic affairs and counseling include helping students develop an appreciation of the role of self-regulation in college success.

  7. Challenging Notions of Academic Entitlement and Its Rise among Liberal Arts College Students

    Directory of Open Access Journals (Sweden)

    Debra Lemke

    2017-12-01

    Full Text Available To assess academic entitlement, we employed a repeated cross-sectional design to compare survey data from two systematic random samples collected eight years apart, in 2009 (n = 225 and 2017 (n = 159, at a small, private, mid-Atlantic liberal arts college. According to an entitlement scale (based on Greenberger et al., 2008, students were less likely to be entitled in 2017 (27% than in 2009 (41% (p = 0.02. In 2009, a higher proportion of males than females felt entitled (50% versus 34%, p = 0.05, a sex difference that disappeared by 2017. To explore academic entitlement further, we developed the “PIE” scale to measure the extent to which students believe “participation,” “improvement” and “effort” should help determine their course grades. Although the proportion of above average PIE scorers was stable from 2009 (36% to 2017 (34%, in 2017, more females than males were above average on PIE (26% of males versus 44% of females, p = 0.02. PIE, or the desire for recognition of “academic sweat equity,” could reflect students’ support for a learning model that goes beyond mastery and is more developmental and process oriented. These data challenge common conceptions of what constitutes academic entitlement, the belief that it is rising, and suggest continued discussions of what factors should determine grades.

  8. Intrahousehold Relations and Environmental Entitlements of Land and Livestock for Women in Rural Kano, Northern Nigeria

    Directory of Open Access Journals (Sweden)

    Saadatu Umaru Baba

    2018-02-01

    Full Text Available Gender relations mediate access to the environment in a variety of ways, through formal institutions such as customary law or informal social norms operating at the household level. This is particularly so in rural areas of the global south that are highly dependent on natural resources for livelihoods. The environmental entitlements framework is useful in examining the influence of informal institutions on access to environmental resources among differentiated social actors. In this paper, we use the environmental entitlements framework to map entitlements to land and livestock, and explore the capabilities they provide for women in rural northern Nigeria. The aim of the study was to examine the influence of social norms governing marriage and inheritance on women’s entitlements to land and livestock. The study methods were qualitative and used in-depth interviews and household case studies. We find that environmental entitlements of land and livestock for women are mediated by their relationships to men, through marriage or kinship, and through the different intra household arrangements within marriage, including seclusion, non-seclusion, and polygyny. Women are able to gain command of natural resources through negotiations within these relationships and within the wider social norms governing Hausa society. While these institutions can restrict the capabilities women derive from natural resources, women may delay or forgo entitlements as a means of enhancing their wellbeing.

  9. Environmental Entitlements: Institutional Influence on Mangrove Social-Ecological Systems in Northern Vietnam

    Directory of Open Access Journals (Sweden)

    Steven E. Orchard

    2015-11-01

    Full Text Available Environment and development issues are complex and interdependent. Institutions underpinning state, private sector and civil society actions at various levels must address complexity to ensure social-ecological system integrity. However, responses often operate at only one governance level, with limited interactions with other levels, restricting their ability to support communities who depend on natural resources for their livelihoods. This paper explores institutional factors influencing household entitlements to mangrove system provisioning goods on Vietnam’s northern coast. The environmental entitlements framework is used to identify: (1 current formal and informal institutional structures relating to mangrove systems; (2 the influence of state, private sector and non-governmental organisation actors at various levels; and (3 how actions occurring at and among various levels of governance shape mangrove system entitlements at the local level. Employing a case study approach, this research utilises qualitative methods and a multi-level governance approach to understand prevailing institutional contexts. Results indicate that reforms occurring within weak regulatory frameworks led to the concentration of power at the meso level, reducing the endowments of marginalized households. Market forces facilitated inequality and environmental degradation, negatively impacting household entitlements. Finally, a lack of formally recognised civil society constrained household capabilities to participate in mangrove planning. Mangrove dependent households must be integrated into mangrove planning at the local level, as processes at higher institutional levels affect household environmental entitlements and threaten sustainable outcomes. Ensuring views from the local level feed into the multi-level governance process is vital.

  13. Testing the concept of relational entitlement in the dyadic context: further validation and associations with relationship satisfaction.

    Science.gov (United States)

    George-Levi, Sivan; Vilchinsky, Noa; Tolmacz, Rami; Liberman, Gabriel

    2014-04-01

    The sense of relational entitlement is the perception one has of what one deserves from one's partner, and it may play a crucial role in determining the quality of a couple's relationship. However, the concept was only recently subjected to empirical examination. The main goals of the current study were to continue the work initiated by the scale developers (Tolmacz & Mikulincer, 2011) by (1) further validating the Sense of Relational Entitlement Scale (SRE) in a sample of adult couples; and (2) examining the contribution of each partner's sense of relational entitlement to his or her own and his or her partner's relationship satisfaction. A sample of 120 Israeli, heterosexual, older couples (age = 58 years) in long-term relationships completed the study measurements. Factor analyses revealed that the SRE scale consisted of two major dimensions: conflicted entitlement and assertive entitlement. Applying an Actor-Partner-Interdependence Model (APIM) analysis indicated that the more conflicted one felt with regard to what one was entitled to, the less satisfaction one felt with the relationship. Additionally, the higher one's entitlement expectations were of one's partner (a subfactor of the assertive entitlement dimension), the more one's partner was satisfied with the relationship. The sense of entitlement construct seems to be relevant to the context of dyadic relationships and, as such, is worthy of further attention and investigation.

    Full Text Available It is important that married couples seek legal advice with regard to the assets falling within their joint estate, more particularly their retirement benefits. This article reflects on the entitlement (if any of non-member spouses to their spouses' retirement fund benefits. Pension benefits can be due before, during or after divorce, and parties to the marriage should be aware of their rights with regard to the accruing pension benefits of their spouses. While it is settled law that non-member spouses are entitled to receive a portion of their member spouses' pension benefits (known as "pension interest" immediately on divorce, it is not particularly clear whether non-member spouses are also entitled to receive the same before or sometime after divorce. In this article I provide a contextual understanding of the entitlements (if any which spouses or former spouses of members of pension funds have on such member spouses' retirement benefits. Furthermore, it shown in this article that various divisions of South African High Courts have been inconsistent in how they have approached the issue of the pension interest between divorcing spouses or divorced ex-spouses.

    Miller, Joshua D.; Price, Joanna; Campbell, W. Keith

    2012-01-01

    Some scholars have called for the replacement of the Narcissistic Personality Inventory (NPI) with more narrow scales measuring grandiosity and entitlement instead. In the current study, the authors examined the relations among the NPI and measures of grandiosity and entitlement, as well as in relation to a measure of the Five-Factor Model (FFM).…

    2017-12-01

    Dating violence continues to be pervasive among college students (Stappenbeck & Fromme, 2010). Given the paucity of research investigating the various pathways through which risk factors are linked to dating violence among different college campuses, we use multiple group path analysis to examine the role of child abuse, self-control, entitlement, and risky behaviors on dating violence perpetration among college students from one Southeastern and one Midwestern university. There were 1,482 college students (51% female) enrolled in undergraduate courses at 2 large public universities who completed paper and pencil surveys. Dating violence perpetration was directly associated with gender, child physical abuse, and sexual and drug risk behaviors and indirectly associated with college Greek letter fraternity affiliation, self-control, and entitlement. Moreover, significant differences in the pathways to dating violence were found between the Southeast and Midwest campuses.

  13. Moral Entitlements and Aspiration Formation in Asymmetric Bargaining: Experimental Evidence from Germany and China

    Directory of Open Access Journals (Sweden)

    Heike Hennig-Schmidt

    2017-10-01

    Full Text Available Using a unique experimental data set, we investigate how asymmetric legal rights shape bargainers’ aspiration levels through moral entitlements derived from equity norms and number prominence. Aspiration formation is typically hard to observe in real life. Our study involves 15 negotiations from Germany and China. Over the course of the negotiation, bargainers discuss the distribution of an amount of money by alternating offers until they consent or break off. Legal rights are randomly assigned by asymmetric outside options. We videotape and code the in-group discussions. In total, verbal data from 30 groups, 1100 pages of transcripts, and 65 h of discussions are content-analyzed. Our main finding is that strong groups derive and defend moral entitlements from equity concerns with regard to their outside options. They strive for equitable but unequal distributions (e.g., proportional split and split the difference. Moral entitlements materialize in the recorded aspiration levels and final payoffs, which exceed the equal split. By contrast, weak groups aim at equality. Over the course of the negotiation, equity tends to lose, while the prominence of round numbers gains importance. Similarities between the subject pools are found in that equity and prominence are both decisive for the formation of aspiration levels. Chinese negotiations are characterized by long periods of stagnation, only minimal concessions, and the communication of false goals. By contrast, Germans steadily reduce their goals and make concessions.

  14. Agentic and communal narcissism and satisfaction with life: The mediating role of psychological entitlement and self-esteem.

    2017-10-01

    This study examined the mediational role of self-esteem (as an enhancement) and psychological entitlement (as a cost) in the relationship between an agentic-communal model of grandiose narcissism and satisfaction with life. Two hundred and forty-eight university undergraduate students completed measures of agentic and communal narcissism, self-esteem, psychological entitlement and satisfaction with life. The findings suggest that there is support for the usefulness of the agentic-communal model of narcissism, and, consistent with predictions in the wider literature, self-esteem and psychological entitlement mediated the relationship between agentic-communal narcissism and life satisfaction. © 2015 International Union of Psychological Science.

    Full Text Available In December 2014 in volume 60 issue 4 a paper was published entitled “A Framework for Evaluation of Marine Spatial Data Geoportals Using Case Studies” by Marina Tavra, Vlado Cetl and Tea Duplancic Leder which is suspected to constitute academic misconduct. This comment reasons that the core of the paper was taken from another source and thus does not offer new and original scientific work and therefore does not add knowledge to the body of science. Furthermore it argues that apart from the plagiarism the paper shows major weaknesses and thus should have not been published even it was not plagiarized.

    Research into the relationship between self-esteem and narcissism has produced conflicting results, potentially caused by hidden subpopulations that exhibit distinct positive or negative associations. This research uses Latent Profile Analysis to identify profiles within a national panel study (N = 6,471) with differing relationships between psychological entitlement and self-esteem. We identified a narcissistic self-esteem profile (9%) characterised by high entitlement and high self-esteem, ...

  18. Effects of customer entitlement on service workers' physical and psychological well-being: a study of waitstaff employees.

    Fisk, Glenda M; Neville, Lukas B

    2011-10-01

    This exploratory study examines the nature of customer entitlement and its impact on front-line service employees. In an open-ended qualitative inquiry, 56 individuals with waitstaff experience described the types of behaviors entitled customers engage in and the kinds of service-related "perks" these individuals feel deserving of. Participants explained how they responded to entitled customers, how and when managers became involved, and how their dealings with these patrons influenced their subjective physical and psychological well-being. We found that the behaviors of entitled customers negatively impacted waitstaff employees. Participants reported physiological arousal, negative affect, burnout, and feelings of dehumanization as a result of dealing with these patrons. While respondents drew on a variety of strategies to manage their encounters with entitled customers, they indicated workplace support was often informal and described feeling abandoned by management in dealing with this workplace stressor. Approaching customer entitlement as a form of microaggression, we offer recommendations for practice and suggest new directions for future research. .

    Directory of Open Access Journals (Sweden)

    Ratna Asmarani

    2017-04-01

    Full Text Available The aim of the paper entitled ―Victorian Femme Fatale in Mary Elizabeth Braddon‘s Novel Entitled Lady Audley‟s Secret‖ is to analyze the intricate life of the female main character as a representation of Victorian femme fatale. Feminist criticism and gynocritics are used as a frame of analysis supported by the concepts of femme fatale, fatalism, and Victorian femininity. The result indicates that although femme fatale is fatal to men, she leads a fatalistic life in a patriarchal Victorian society. Her success to pursue a wealthy life using her femininity is short-lived followed by years of exile in a private and luxurious asylum. Through her portrayal of the female main character‘s life as a femme fatale, the female writer launches two-edged criticism. She criticizes the woman who exploits her femininity to get excessive material gain and at the same time she criticizes the Victorian society which prevents a single (-parent woman to have a decent life using her skills not her femininity.

    Gangl, Markus; Ziefle, Andrea

    2015-09-01

    The authors investigate the relationship between family policy and women's attachment to the labor market, focusing specifically on policy feedback on women's subjective work commitment. They utilize a quasi-experimental design to identify normative policy effects from changes in mothers' work commitment in conjunction with two policy changes that significantly extended the length of statutory parental leave entitlements in Germany. Using unique survey data from the German Socio-Economic Panel and difference-in-differences, triple-differenced, and instrumental variables estimators for panel data, they obtain consistent empirical evidence that increasing generosity of leave entitlements led to a decline in mothers' work commitment in both East and West Germany. They also probe potential mediating mechanisms and find strong evidence for role exposure and norm setting effects. Finally, they demonstrate that policy-induced shifts in mothers' preferences have contributed to. retarding women's labor force participation after childbirth in Germany, especially as far as mothers' return to full-time employment is concerned.

    Science.gov (United States)

    Rasmussen, Kyler

    2016-07-01

    Narcissism has long been used to predict aggressive or vengeful responses to provocations from others. The strength of this relation can, however, vary widely from study to study. Narcissism and revenge were examined in 84 independent samples (N = 11297), along with the moderating role of sample type (i.e., child/adolescent, prisoner, undergraduate, or general samples), type of narcissism measure used (i.e., Narcissistic Personality Inventory, Psychological Entitlement Scale, Short D3, etc.), the nature of the provocation, and the type of provoked aggression examined. Narcissism was positively related to provoked aggression across studies (ρ = .25), but that relation was stronger in child/adolescent samples (ρ = .36) and when measures of entitlement or vulnerable narcissism were employed (ρ = .29). Implications for practical research, as well as neglected areas of research on narcissism and provoked aggression are discussed. Aggr.

  2. Economic Entitlements via Entrepreneurial Conduct? Women and Financial Inclusion in Neo-liberal India

    Directory of Open Access Journals (Sweden)

    K. Kalpana

    2015-08-01

    Full Text Available This paper examines the gendered local character of neoliberalism at the household level by focusing on microcredit/finance programs in India. Microfinance promoted by the state as an informal activity targeting women is intended to alleviate income inequalities, even as it contributes to maintaining the world capitalist system. In India the inception of microfinance-based Self Help Groups (SHGs or peer groups of women savers and borrowers in the 1990s has coincided with a rightward turn towards neoliberal policies of structural adjustment, privatization and economic deregulation. In this paper, I show how Indian policy makers have endeavored to make women's economic entitlements contingent upon their disciplined financial behavior and their willing participation in neoliberal agendas of creating and deepening 'self-regulating' markets at village levels. Drawing on an ethnographic study conducted in a South Indian state, I show that the community level 'neoliberal disciplining' that microfinance entails does not proceed without resistance. Whilst SHGs seek to constitute women as fiscally disciplined savers and borrowers, women stake their 'rightful' entitlement to bank credit even as they reject outright the entrepreneurial subjectivities they are expected to assume. They pursue purposes and ends that extend well beyond 'financial inclusion.'

    Ninety-eight pictures painted in the Middle Ages and later entitled "Christ as Pharmacist" are shown in a little German book (W. H. Hein, Christus als Apotheker, Govi-Verlag, Frankfurt am Main, 1974). In the three paintings shown here, Christ appears as a pharmacist standing behind a pharmacy table used to compound medicine, and he has a medicinal balance in his left hand. The Christian terms, such as faith, love, and hope, and the drug's name are written on each of the drug vase labels. It seems that the purpose of displaying these paintings in a pharmacy was both to propagate Christianity to the poor who bought medicine at their family pharmacy and to win their respect for the pharmacist.

    An international conference entitled "Zdenek Kopal's Binary Star Legacy" was held on the occasion of the late Professor Kopal's 90th birthday in his home town of Litomyšl/Czech Republic and dedicated to the memory of one of the leading astronomers of the 20th century. Professor Kopal, who devoted 60 years of his scientific life to the exploration of close binary systems, initiated a breakthrough in this field with his description of binary components as non-spherical stars deformed by gravity, with surfaces following Roche equipotentials. Such knowledge triggered the development of new branches of astrophysics dealing with the structure and evolution of close binaries and the interaction effects displayed by exciting objects such as cataclysmic variables, symbiotic stars or X-ray binaries. Contributions to this conference included praise of the achievements of a great astronomer and personal reminiscences brought forward by Kopal's former students and colleagues, and reflected the state of the art of the dyn...

    2016-01-01

    Our commentary on Forman et al paper explores their thesis that right to health language can frame global health policy responses. We examined human rights discourse in the outcome documents from three 2015 United Nations (UN) summits and found rights-related terms are used in all three. However, a deeper examination of the discourse finds the documents do not convey the obligations and entitlements of human rights and international human rights law. The documents contain little that can be used to empower the participation of those already left behind and to hold States and the private sector to account for their human rights duties. This is especially worrying in a neoliberal era. PMID:27285518

    2016-01-01

    Many scholars have called for an increased focus on positive aspects of sexual health and sexuality. Using a longitudinal design with two assessments, we investigated patterns of entitlement to sexual partner pleasure and self-efficacy to achieve sexual pleasure among 295 young men and women aged 17–25 years attending one Australian university. We also tested whether entitlement and efficacy differed by gender, and hypothesized that entitlement and efficacy would be higher in older participants and those with more sexual experience. A sense of entitlement to sexual partner pleasure increased significantly over the year of the study, whereas, on average, there was no change in self-efficacy over time. At Time 1 (T1), young women reported more entitlement than young men. Age was positively associated with T1 entitlement, and experience with a wider range of partnered sexual behaviors was concurrently associated with more entitlement and efficacy and was also associated with increased entitlement to partner pleasure and increased self-efficacy in achieving sexual pleasure at T2 relative to T1. A group with the least amount of sexual experience was particularly low in entitlement and efficacy when compared to groups with a history of coital experience. There was no evidence that any association differed between young men and young women. Limitations of the study include a sample of predominantly middle class, Caucasian students at one university and the possibility that students more interested in sex and relationships, and with more sexual experience, chose to participate.

    Background The Vaccines for Children (VFC) program provides vaccines at no cost to children who are Medicaid-eligible, uninsured, American Indian or Alaska Native (AI/AN), or underinsured and vaccinated at Federally Qualified Health Centers or Rural Health Clinics. The objective of this study was to compare influenza vaccination coverage of VFC-entitled to privately insured children in the United States, nationally, by state, and by selected socio-demographic variables. Methods Data from the National Immunization Survey-Flu (NIS-Flu) surveys were analyzed for the 2011–2012 and 2012–2013 influenza seasons for households with children 6 months–17 years. VFC-entitlement and private insurance status were defined based upon questions asked of the parent during the telephone interview. Influenza vaccination coverage estimates of children VFC-entitled versus privately insured were compared by t-tests, both nationally and within state, and within selected socio-demographic variables. Results For both seasons studied, influenza coverage for VFC-entitled children did not significantly differ from coverage for privately insured children (2011–2012: 52.0% ± 1.9% versus 50.7% ± 1.2%; 2012–2013: 56.0% ± 1.6% versus 57.2% ± 1.2%). Among VFC-entitled children, uninsured children had lower coverage (2011–2012: 38.9% ± 4.7%; 2012–2013: 44.8% ± 3.5%) than Medicaid-eligible (2011–2012: 55.2% ± 2.1%; 2012–2013: 58.6% ± 1.9%) and AI/AN children (2011–2012: 54.4% ± 11.3%; 2012–2013: 54.6% ± 7.0%). Significant differences in vaccination coverage among VFC-entitled and privately insured children were observed within some subgroups of race/ethnicity, income, age, region, and living in a metropolitan statistical area principle city. Conclusions Although finding few differences in influenza vaccination coverage among VFC-entitled versus privately insured children was encouraging, nearly half of all children were not vaccinated for influenza and coverage was

    Full Text Available This library research aimed at finding the three aspect of discourse analysis: contextual, grammatical and lexical aspect of Michael Heart’s song lyrics entitled “We will not go down (Song for Gaza. After analysis it can be found that the life experience and background of the song writer and singer is closely related to the idea proposes within the song lyrics. Whereas, the result of the grammatical and lexical analysis gives a depiction of cohesion and coherence of the song discourse of “We will not Go Down (Song for Gaza”. There are eight (8 forms of first plural personal pronoun of “We”, four (4 second plural personal pronoun of ‘You” and seven (7 third personal pronouns in various forms. On the other side, it is difficult to find lexical aspects of this song discourse. There is only one form of anaphoric repetition. The repetition of the sentence “We Will Not Go Down” seven times is to influence the hearers whether they are supporters or opponents of the idea brought by the singer/the author that whatever happens Palestinian people will not surrender to every force, nation or people that want to colonialize them.

    2016-08-29

    The recent reform of the English National Health Service (NHS) through the Health and Social Care Act of 2012 introduced important changes in the organization, management, and provision of public health services in England. This study aims to analyze the NHS reforms in the historical context of predominance of neoliberal theories since 1980 and to discuss the "liberalization" of the NHS. The study identifies and analyzes three phases: (i) gradual ideological and theoretical substitution (1979-1990) - transition from professional and health logic to management and commercial logic; (ii) bureaucracy and incipient market (1991-2004) - structuring of the bureaucracy focused on administration of the internal market and expansion of pro-market measures; and (iii) opening to the market, fragmentation, and discontinuity of services (2005-2012) - weakening of the territorial health model and consolidation of health as an open market for public and private providers. This gradual but constant liberalization has closed services and restricted access, jeopardizing the system's comprehensiveness, equity, and universal healthcare entitlement in the NHS.

  15. Between welfare medicine and mainstream entitlement: Medicaid at the political crossroads.

    Science.gov (United States)

    Grogan, Colleen; Patashnik, Eric

    2003-10-01

    As the new century begins, the Medicaid program is arguably at a political crossroads. Over the 1980s and 1990s, policy makers enacted major expansions in Medicaid coverage, offering significant new health benefits to poor women and children and other constituencies. In elite rhetoric and political framing, Medicaid was increasingly cast as a broad-based social welfare entitlement of value to all Americans, including middle-class citizens. Some health care advocates began viewing Medicaid expansions as a potential path to achieving universal coverage in the United States. Yet Medicaid remains a means-tested program that has been repeatedly threatened with policy retrenchment. In this essay, we scrutinize Medicaid's current status and future possibilities from a historical-institutional perspective by tracing its complex evolution since its enactment in the Social Security Amendments of 1965. Our core claim is that decisions made at the time of Medicaid's original adoption have fundamentally set the matrix for struggles over the program's unfolding development. We demonstrate that key ambiguities embedded in the 1965 act created largely unintended opportunities for policy entrepreneurs to broaden Medicaid's scale and scope as well as foreseeable vulnerabilities that must be overcome if Medicaid is to realize its full potential.

    2009-10-01

    In 2006, Germany's sixth national health target entitled "Depressive illnesses - prevention, early diagnosis, sustainable treatment" was developed by an interdisciplinary group of experts. A total of six areas of activity and proposals for action with potential for improvement were defined. Subsequently, a group of experts was entrusted with designing evaluation strategies, defining indicators of progress, and examining the accessibility of data sources for evaluation. For the primary start-up activities set out in the health targets, specific progress indicators were deduced, and routine data available for evaluation were identified. As a next step, the limitations of these data sources were analyzed and necessary improvements described. Relevant indicators of progress for specific areas of activity have been described, the availability and usability of different existing data sources examined, and further supplements or additional specifications with respect to the indicators described. Due to inadequate data sources, additional systematic surveys are required to evaluate the health target and its implementation. Existing German surveys should be extended by questions concerning relevant measures and progress indicators; various progress indicators should be analyzed on a general basis.

    1997-01-01

    Since 1981, the US government has funded a program promoting sexual abstinence among young people through its Office of Population's Adolescent Family Life Demonstration Grants program (AFLA). A 1983 court challenge which held that AFLA violated the separation of church and state by endorsing a particular religious viewpoint was settled out of court in 1993 with stipulations that AFLA-funded sexuality education must not include religious references, must be medically accurate, must respect the principle of self-determination of teenagers regarding contraceptive referrals, and must not be implemented on church property. Critics continue to charge that AFLA's abstinence-only programs have failed to receive proper evaluation. While AFLA has no broad-based support, it is backed by the same small group of Congressional proponents who are attempting to promote broad-scale, federally-funded abstinence-only programs. Thus, the August 1996 welfare reform legislation represents the broadest attack on the provision of comprehensive sexuality education in the US. While opponents of sexuality education could not restrict the content of education programs, they could restrict programs through health policy and funding mechanisms. Congress, thus, mandated $50 million a year for 1998-2002 to a matching grant with entitlement status, which was tagged on to final versions of the larger welfare reform bill. The intent of this action was to use federal law to change the social norm of premarital sexual activity. Funds will not go to programs which discuss contraception. Additional problems with the statute include misinformation, ambiguity, and a lack of evaluation requirements. It remains for states to decide whether to accept the restricted funds and for parties on both sides of the issue to continue to lobby for their positions.

    Full Text Available The title of this study is, “An Analysis of Figurative Languages Used in Paulo Coelho’s novel Entitled “The Alchemist”. The objectives of the study are to describe the types of the figurative language found in the book and to identify the contextual meaning of the figurative language. The method used in collecting the data related to the subject of this research is documentation method because the researcher collected the data from novel. This study was conducted by collecting any relevant data and information about the topic or problem of the study from novels and internet that are available for the analysis. The data collection used the following steps: reading the novel, and then selecting the data that used the types of figurative language. While the steps to analyze the data are identifying the types of figurative language according to Leech, identifying the contextual meaning of the figurative language, and the last is interpreting the data.The result shows that there are 70 sentences that have figurative language. From all the sentences, there are 30 items or 42.9% of simile, 27 items or 38.6% of personification, 12 items or 17.1% of metaphor, and 1 item or 1.4% of hyperbole. It can be indicated that the dominant type of figurative language in the novel is simile. The author uses simile to explain circumstances, to describe the characters, to express emotion of the characters, and to make his writing more vivid and entertaining. It can be concluded that figurative language has important roles in this novel. That‘s why the author used so many sentences that have figurative language in this novel. Using figurative language makes the novel more interesting to read, and helps the readers to imagine the story, the character based on the illustration that the author has already given in the story.

  2. College instruction is not so stress free after all: A qualitative and quantitative study of academic entitlement, uncivil behaviors, and instructor strain and burnout.

    2017-12-01

    The vast majority of today's college students are millennials, who have traits of confidence, tolerance, but also of entitlement and narcissism (Twenge, 2006). Therefore, college instructors face a unique challenge: dealing with the requests from academically entitled students, who have unreasonable expectations of receiving academic success, regardless of performance (Chowning & Campbell, 2009). We conducted two studies to examine whether student academic entitlement would increase instructors' strain and burnout via uncivil behaviors. A qualitative inquiry asked 136 instructors with college-teaching experience to describe types of behaviors entitled students display, their responses to entitled students, and the influence of these interactions on instructors' well-being. Next, a quantitative study with data from 857 college students nested in 34 instructors tested a multilevel mediation model where students' academic entitlement was related to instructor-reported uncivil behaviors, which in turn related to instructors' strain and burnout. Both studies largely support our hypothesis that uncivil behaviors fully mediate the relationship between students' academic entitlement and instructors' strain and burnout. We recommend employing behavioral modification strategies to decrease uncivil behaviors (e.g., class rules regarding uncivil behaviors might be specified in the course syllabus and consistently enforced) because academic entitlement attitudes are largely stable beliefs and thus may be less amenable to modification.

    This paper comments the letter entitled "Network analysis of the state space of discrete dynamical systems" by A. Shreim et al. [Physical Review Letters, 98, 198701 (2007)]. We found that some theoretical analyses are wrong and the proposed indicators based on parameters of phase network can not discriminate dynamical complexity of the discrete dynamical systems composed by 1-D Cellular Automata.

  5. Transfer of single farm payment entitlements to farm successors: impact on structural change and rental prices in Switzerland

    Directory of Open Access Journals (Sweden)

    Gabriele Mack

    2013-09-01

    Full Text Available This paper analyses the impact of tradable and non-tradable single farm payment (SFP entitlements for farm successors on structural change and the lease market. Using the example of Swiss agriculture, the effects on rental-price trends and farm-exit rates are investigated. An ex-ante normative impact analysis is performed with the agent-based agricultural-sector model SWISSland, which simulates structural change processes and income trends in Swiss agriculture over a period of up to 15 years. A land market implemented at municipality level simulates the plot-by-plot leasing of land to surrounding neighbouring agents that is common in Switzerland. Allocation of plots to tenants as well as lease pricing is modelled taking into account the farm-specific land rents. The results show that personalised SFP entitlements which could not be transferred to a farm successor not only cause an intensification of structural change, but would also thus lead to a substantial reduction in rental prices. SFP entitlements which were successfully transferred to farm successors have only a slight impact on structural change and the rental prices of arable land. Only for grassland in the mountain region does a stronger shift result in a significant reduction in rental prices.

    prices and rainfall patterns due to climate change only enhance these concerns. Given these deficiencies, any corrective strategy should at least target the following long-term policy goals: a) increase the efficiency of rural electricity consumption in terms of grain production and rural income, b) providing the farmers greater flexibility with timely, high quality energy and more efficient means of production, c) enable proper energy accounting on the use side so as to recover costs at sufficient levels for the SEBs and thus enable long-term investments in energy infrastructure and d) secure and eventually increase agricultural production without depleting groundwater resources over the long run. We will present an entitlement approach with which the above issues can be addressed in the future. A case study example from the semi-arid Telangana Region in Andhra Pradesh will be discussed in depth and preliminary results shown.

    Purpose To further our insight into the role of networks in health system reform, the purpose of this paper is to investigate how one agency, the NSW Agency for Clinical Innovation (ACI), and the multiple networks and enabling resources that it encompasses, govern, manage and extend the potential of networks for healthcare practice improvement. Design/methodology/approach This is a case study investigation which took place over ten months through the first author's participation in network activities and discussions with the agency's staff about their main objectives, challenges and achievements, and with selected services around the state of New South Wales to understand the agency's implementation and large system transformation activities. Findings The paper demonstrates that ACI accommodates multiple networks whose oversight structures, self-organisation and systems change approaches combined in dynamic ways, effectively yield a diversity of network governances. Further, ACI bears out a paradox of "centralised decentralisation", co-locating agents of innovation with networks of implementation and evaluation expertise. This arrangement strengthens and legitimates the role of the strategic hybrid - the healthcare professional in pursuit of change and improvement, and enhances their influence and impact on the wider system. Research limitations/implications While focussing the case study on one agency only, this study is unique as it highlights inter-network connections. Contributing to the literature on network governance, this paper identifies ACI as a "network of networks" through which resources, expectations and stakeholder dynamics are dynamically and flexibly mediated and enhanced. Practical implications The co-location of and dynamic interaction among clinical networks may create synergies among networks, nurture "strategic hybrids", and enhance the impact of network activities on health system reform. Social implications Network governance requires more

  13. Sources of self-categorization as minority for mixed-race individuals: Implications for affirmative action entitlement.

    Good, Jessica J; Chavez, George F; Sanchez, Diana T

    2010-10-01

    Multiracial individuals are in the unique position of being able to categorize themselves as members of multiple racial groups. Drawing on self-categorization theory, we suggest that similarity to the minority ingroup depends on self-perceptions of physical appearance and connectedness to the minority ingroup. Moreover, we argue that similarity to the ingroup determines self-categorization as minority, which predicts category-based entitlements such as perceived eligibility for minority resources (e.g., affirmative action). Using path analysis, we found support for this model on a convenience sample of 107 mixed-race minority-White participants. The results suggest that affective processes rather than observable characteristics such as prototypical physical appearance better predict self-categorization among mixed-race individuals.

  15. The meaning of working in black and white managerial samples with specific reference to sense of entitlement

    1995-06-01

    Full Text Available Wealth distribution and wealth creation are probably the most important challenges to be faced by South African government. At the organisational level, it will be required of each employee to accept responsibility for contributing to organisational success. The formation of multi-cultural work teams gives relevance to the study of meaning of work and specifically, to the sense of entitlement as a manifestation of a need for equity. In this study it was found that black managers experience a stronger sense of entitlement than their white colleagues/ which is ascribed to deprivation in the past. Although affirmative action could be implemented as a compensatory measure, the caveats involved make it imperative to consider other alternatives. Hence, it is proposed that management systems should be redesigned to promote egalitarianism in the workplace. Opsomming Die verdeling en skepping van welvaart is waarskynlik die belangrikste uitdagings wat die Suid-Afrikaanse regering die hoof moet bied. Op ondernemingsvlak sal daar dus van eike werknemer verwag word om verantwoordelikheid vir 'n betekenisvolle bydrae tot organisasie-sukses te aanvaar. Die vorming van multi-kulturele groepe skep relevansie vir die bestudering van die betekenis van werk, en spesifiek die sin vir geregtigdheid,1 as 'n manifestasie van 'n behoefte aan billikheid. In hierdie studie is daar gevind dat swart bestuurders 'n sterker sin vir geregtigdheid as hulle wit kollegas ervaar. Dit word aan deprivasie in die verlede toegeskryf. Ofskoon regstellende aksie as 'n kompenserende maatreel geimplementeer sou kon word, skep die leemtes hieraan verbonde 'n behoefte aan oorweging van alternatiewe moontlikhede. Daar word derhalwe aanbeveel dat bestuurstelsels herontwerp word om gelykheid in die werkpiek te bevorder.

    2017-08-01

    A growing body of research attests to the impact of welfare regimes on health and health equity. However, the mechanisms that link different kinds of welfare entitlement to health outcomes are less well understood. This study analysed the accounts of 29 older adults in England to delineate how the form of entitlement to welfare and other resources (specifically, whether this was understood as a universal entitlement or as targeted to those in need) impacts on the determinants of health. Mechanisms directly affecting access to material resources (through deterring uptake of benefits) have been well documented, but those that operate through psychosocial and more structural pathways less so, in part because they are more challenging to identify. Entitlement that was understood collectively, or as arising from financial or other contributions to a social body, had positive impacts on wellbeing beyond material gains, including facilitating access to important health determinants: social contact, recognition and integration. Entitlement understood as targeted in terms of individualised concepts of need or vulnerability deterred access to material resources, but also fostered debate about legitimacy, thus contributing to negative impacts on individual wellbeing and the public health through the erosion of social integration. This has important implications for both policy and evaluation. Calls to target welfare benefits at those in most need emphasise direct material pathways to health impact. We suggest a model for considering policy change and evaluation which also takes into account how psychosocial and structural pathways are affected by the nature of entitlement.

    Declarative Networking is a programming methodology that enables developers to concisely specify network protocols and services, which are directly compiled to a dataflow framework that executes the specifications. Declarative networking proposes the use of a declarative query language for specifying and implementing network protocols, and employs a dataflow framework at runtime for communication and maintenance of network state. The primary goal of declarative networking is to greatly simplify the process of specifying, implementing, deploying and evolving a network design. In addition, decla

    2001-01-01

    Stereotypes of older people suggest that they may experience more sickness and injury therefore may not be as productive as younger employees. The present paper attempts to test these stereotypes and reports research into patterns of sick leave in different age cohorts and attitudes towards the use of sick leave. The research was carried out at two case study sites. Managers were interviewed and focus groups were held with workers. A complex pattern was found, suggesting structural issues such as sick leave entitlements, workplace organisation, and flexible work patterns interacted with managers' and workers' attitudes, age, gender and family responsibilities. Flexible workplace hours, and part payment for unused sick leave and insecurity of employment appeared as important factors in reducing absenteeism. The most striking finding was that older workers past pensionable age took the least sick leave. Older workers were careful to conserve sick leave as a 'cushion' for serious illness. Workplace pressures especially those resulting from the failure of management to replace absent workers resulted in work pressure on peers and thus reluctance of workers to take leave.

    In this project, developed scheduling frameworks for dynamic bandwidth demands for large-scale science applications. In particular, we developed scheduling algorithms for dynamic bandwidth demands in this project. Apart from theoretical approaches such as Integer Linear Programming, Tabu Search and Genetic Algorithm heuristics, we have utilized practical data from ESnet OSCARS project (from our DOE lab partners) to conduct realistic simulations of our approaches. We have disseminated our work through conference paper presentations and journal papers and a book chapter. In this project we addressed the problem of scheduling of lightpaths over optical wavelength division multiplexed (WDM) networks. We published several conference papers and journal papers on this topic. We also addressed the problems of joint allocation of computing, storage and networking resources in Grid/Cloud networks and proposed energy-efficient mechanisms for operatin optical WDM networks.

    To describe the prevalence and patterns of rape perpetration in a randomly selected sample of men from the general adult population, to explore factors associated with rape and to describe how men explained their acts of rape. Cross-sectional household study with a two- stage randomly selected sample of men. 1737 South African men aged 18-49 completed a questionnaire administered using an Audio-enhanced Personal Digital Assistant. Multivariable logistic regression models were built to identify factors associated with rape perpetration. In all 27.6% (466/1686) of men had raped a woman, whether an intimate partner, stranger or acquaintance, and whether perpetrated alone or with accomplices, and 4.7% had raped in the last 12 months. First rapes for 75% were perpetrated before age 20, and 53.9% (251) of those raping, did so on multiple occasions. The logistic regression model showed that having raped was associated with greater adversity in childhood, having been raped by a man and higher maternal education. It was associated with less equitable views on gender relations, having had more partners, and many more gender inequitable practices including transactional sex and physical partner violence. Also drug use, gang membership and a higher score on the dimensions of psychopathic personality, namely blame externalisation and Machiavellian egocentricity. Asked about why they did it, the most common motivations stemmed from ideas of sexual entitlement. Perpetration of rape is so prevalent that population-based measures of prevention are essential to complement criminal justice system responses. Our findings show the importance of measures to build gender equity and change dominant ideas of masculinity and gender relations as part of rape prevention. Reducing men's exposure to trauma in childhood is also critically important. © 2011 Jewkes et al.

    Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that some universal laws might accurately describe the dynamics of these networks, albeit the nature and common origin of such laws remain elusive. Here we show that the causal network representing the large-scale structure of spacetime in our accelerating universe is a power-law graph with strong clustering, similar to many complex networks such as the Internet, social, or biological networks. We prove that this structural similarity is a consequence of the asymptotic equivalence between the large-scale growth dynamics of complex networks and causal networks. This equivalence suggests that unexpectedly similar laws govern the dynamics of complex networks and spacetime in the universe, with implications to network science and cosmology.

    Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that some universal laws might accurately describe the dynamics of these networks, albeit the nature and common origin of such laws remain elusive. Here we show that the causal network representing the large-scale structure of spacetime in our accelerating universe is a power-law graph with strong clustering, similar to many complex networks such as the Internet, social, or biological networks. We prove that this structural similarity is a consequence of the asymptotic equivalence between the large-scale growth dynamics of complex networks and causal networks. This equivalence suggests that unexpectedly similar laws govern the dynamics of complex networks and spacetime in the universe, with implications to network science and cosmology. PMID:23162688

    To understand challenges in care after stillbirth and provide tailored solutions. Multi-centre case study. Three maternity hospitals. Parents with a stillborn baby, maternity staff. Thematic analysis of parent interviews and staff focus groups and service provision investigation. 1 Themes; 2 Triangulation matrix; 3 Recommendations. Twenty-one women, 14 partners, and 22 staff participated. Service Provision: Care for parents after stillbirth varies excessively; there are misconceptions; post-mortem does not delay follow-up. Women 'do not feel right' before stillbirth; their management is haphazard and should be standardised. Stillbirth is an emergency for parents but not always for staff; communication can seem cold; well-designed bereavement space is critical. Birth: Staff shift priorities to mother and future, but for parents their baby is still a baby; parents are not comfortable with staff recommending vaginal birth as the norm; there are several reasons why parents ask for a caesarean; better care involves clear communication, normal behaviour, and discussion of coping strategies. Post-mortem: Parents are influenced by discussions with staff. Staff should 'sow seeds', clarify its respectful nature, delineate its purpose, and explain the timescale. It is not standardised; parents wish to see their multi-professional team. There is unacceptable variation in care after stillbirth, and insensitive interactions between staff and bereaved parents. Understanding parents' needs, including why they ask for caesarean birth, will facilitate joint decision-making. Every bereaved parent is entitled to good, respectful care. Care too varied & interactions often insensitive after stillbirth; national pathway & training urgently needed PLAIN LANGUAGE SUMMARY: Why and how was the study carried out? Previous studies have shown that improving care after stillbirth is important for families. We investigated the opinions of bereaved parents and maternity staff to find ways to

  14. Interconnected networks

    CERN Document Server

    2016-01-01

    This volume provides an introduction to and overview of the emerging field of interconnected networks which include multi layer or multiplex networks, as well as networks of networks. Such networks present structural and dynamical features quite different from those observed in isolated networks. The presence of links between different networks or layers of a network typically alters the way such interconnected networks behave – understanding the role of interconnecting links is therefore a crucial step towards a more accurate description of real-world systems. While examples of such dissimilar properties are becoming more abundant – for example regarding diffusion, robustness and competition – the root of such differences remains to be elucidated. Each chapter in this topical collection is self-contained and can be read on its own, thus making it also suitable as reference for experienced researchers wishing to focus on a particular topic.

    Full Text Available The language of networks now describes everything from the Internet to the economy to terrorist organizations. In distinction to a common view of networks as a universal, originary, or necessary form that promises to explain everything from neural structures to online traffic, this essay emphasizes the contingency of the network imaginary. Network form, in its role as our current cultural dominant, makes scarcely imaginable the possibility of an alternative or an outside uninflected by networks. If so many things and relationships are figured as networks, however, then what is not a network? If a network points towards particular logics and qualities of relation in our historical present, what others might we envision in the future? In  many ways, these questions are unanswerable from within the contemporary moment. Instead of seeking an avant-garde approach (to move beyond networks or opting out of networks (in some cases, to recover elements of pre-networked existence, this essay proposes a third orientation: one of ambivalence that operates as a mode of extreme presence. I propose the concept of "network aesthetics," which can be tracked across artistic media and cultural forms, as a model, style, and pedagogy for approaching interconnection in the twenty-first century. The following essay is excerpted from Network Ambivalence (Forthcoming from University of Chicago Press.

    Despite substantial recent progress, our understanding of the principles and mechanisms underlying complex brain function and cognition remains incomplete. Network neuroscience proposes to tackle these enduring challenges. Approaching brain structure and function from an explicitly integrative perspective, network neuroscience pursues new ways to map, record, analyze and model the elements and interactions of neurobiological systems. Two parallel trends drive the approach: the availability of new empirical tools to create comprehensive maps and record dynamic patterns among molecules, neurons, brain areas and social systems; and the theoretical framework and computational tools of modern network science. The convergence of empirical and computational advances opens new frontiers of scientific inquiry, including network dynamics, manipulation and control of brain networks, and integration of network processes across spatiotemporal domains. We review emerging trends in network neuroscience and attempt to chart a path toward a better understanding of the brain as a multiscale networked system.

    Our dependence on networks - be they infrastructure, economic, social or others - leaves us prone to crises caused by the vulnerabilities of these networks. There is a great need to develop new methods to protect infrastructure networks and prevent cascade of failures (especially in cases of coupled networks). Terrorist attacks on transportation networks have traumatized modern societies. With a single blast, it has become possible to paralyze airline traffic, electric power supply, ground transportation or Internet communication. How, and at which cost can one restructure the network such that it will become more robust against malicious attacks? The gradual increase in attacks on the networks society depends on - Internet, mobile phone, transportation, air travel, banking, etc. - emphasize the need to develop new strategies to protect and defend these crucial networks of communication and infrastructure networks. One example is the threat of liquid explosives a few years ago, which completely shut down air travel for days, and has created extreme changes in regulations. Such threats and dangers warrant the need for new tools and strategies to defend critical infrastructure. In this paper we review recent advances in the theoretical understanding of the vulnerabilities of interdependent networks with and without spatial embedding, attack strategies and their affect on such networks of networks as well as recently developed strategies to optimize and repair failures caused by such attacks.

    2016-05-08

    Recent British National Health Service (NHS) reforms, in response to austerity and alleged 'health tourism,' could impose additional barriers to healthcare access for non-European Economic Area (EEA) migrants. This study explores policy reform challenges and implications, using excerpts from the perspectives of non-EEA migrants and health advocates in London. A qualitative study design was selected. Data were collected through document review and 22 in-depth interviews with non-EEA migrants and civil-society organisation representatives. Data were analysed thematically using the NHS principles. The experiences of those 'vulnerable migrants' (ie, defined as adult non-EEA asylum-seekers, refugees, undocumented, low-skilled, and trafficked migrants susceptible to marginalised healthcare access) able to access health services were positive, with healthcare professionals generally demonstrating caring attitudes. However, general confusion existed about entitlements due to recent NHS changes, controversy over 'health tourism,' and challenges registering for health services or accessing secondary facilities. Factors requiring greater clarity or improvement included accessibility, communication, and clarity on general practitioner (GP) responsibilities and migrant entitlements. Legislation to restrict access to healthcare based on immigration status could further compromise the health of vulnerable individuals in Britain. This study highlights current challenges in health services policy and practice and the role of non-governmental organizations (NGOs) in healthcare advocacy (eg, helping the voices of the most vulnerable reach policy-makers). Thus, it contributes to broadening national discussions and enabling more nuanced interpretation of ongoing global debates on immigration and health.

    The demands on emergency services have grown relentlessly, and the Institute of Medicine (IOM) has asserted the need for "regionalized, coordinated, and accountable emergency care systems throughout the country." There are large gaps in the evidence base needed to fix the problem of how emergency care is organized and delivered, and science is urgently needed to define and measure success in the emerging network of emergency care. In 2010, Academic Emergency Medicine convened a consensus conference entitled "Beyond Regionalization: Integrated Networks of Emergency Care." This article is a product of the conference breakout session on "Defining and Measuring Successful Networks"; it explores the concept of integrated emergency care delivery and prioritizes a research agenda for how to best define and measure successful networks of emergency care. The authors discuss five key areas: 1) the fundamental metrics that are needed to measure networks across time-sensitive and non-time-sensitive conditions; 2) how networks can be scalable and nimble and can be creative in terms of best practices; 3) the potential unintended consequences of networks of emergency care; 4) the development of large-scale, yet feasible, network data systems; and 5) the linkage of data systems across the disease course. These knowledge gaps must be filled to improve the quality and efficiency of emergency care and to fulfill the IOM's vision of regionalized, coordinated, and accountable emergency care systems. 2010 by the Society for Academic Emergency Medicine.

    This report documents the results of an LDRD program entitled ''Network and Adaptive System of Systems Modeling and Analysis'' that was conducted during FY 2005 and FY 2006. The purpose of this study was to determine and implement ways to incorporate network communications modeling into existing System of Systems (SoS) modeling capabilities. Current SoS modeling, particularly for the Future Combat Systems (FCS) program, is conducted under the assumption that communication between the various systems is always possible and occurs instantaneously. A more realistic representation of these communications allows for better, more accurate simulation results. The current approach to meeting this objective has been to use existing capabilities to model network hardware reliability and adding capabilities to use that information to model the impact on the sustainment supply chain and operational availability.

    Full Text Available Background: Recent British National Health Service (NHS reforms, in response to austerity and alleged ‘health tourism,’ could impose additional barriers to healthcare access for non-European Economic Area (EEA migrants. This study explores policy reform challenges and implications, using excerpts from the perspectives of non-EEA migrants and health advocates in London. Methods: A qualitative study design was selected. Data were collected through document review and 22 indepth interviews with non-EEA migrants and civil-society organisation representatives. Data were analysed thematically using the NHS principles. Results: The experiences of those ‘vulnerable migrants’ (ie, defined as adult non-EEA asylum-seekers, refugees, undocumented, low-skilled, and trafficked migrants susceptible to marginalised healthcare access able to access health services were positive, with healthcare professionals generally demonstrating caring attitudes. However, general confusion existed about entitlements due to recent NHS changes, controversy over ‘health tourism,’ and challenges registering for health services or accessing secondary facilities. Factors requiring greater clarity or improvement included accessibility, communication, and clarity on general practitioner (GP responsibilities and migrant entitlements. Conclusion: Legislation to restrict access to healthcare based on immigration status could further compromise the health of vulnerable individuals in Britain. This study highlights current challenges in health services policy and practice and the role of non-governmental organizations (NGOs in healthcare advocacy (eg, helping the voices of the most vulnerable reach policy-makers. Thus, it contributes to broadening national discussions and enabling more nuanced interpretation of ongoing global debates on immigration and health.

  11. The gap between entitlement and access to healthcare: An analysis of "candidacy" in the help-seeking trajectories of asylum seekers in Montreal.

    In 2012 the Canadian government made significant cuts to its historically strong federal refugee health coverage plan. While this policy had negligible effects on the level of coverage provided to asylum seekers in Quebec, there is evidence that this group nonetheless experienced reduced healthcare access during the period of polarized national debate that ensued. This study engaged the "candidacy" model of healthcare access to illuminate factors contributing to the observed gap between entitlement and access. Twenty-five semi-structured interviews were conducted with asylum seekers in Montreal to elicit narrative accounts of difficulties encountered in the pursuit of healthcare. Thematic content analysis in conjunction with a holistic examination of help-seeking trajectories revealed several important barriers to obtaining care, including widespread confusion and misinformation about refugee health coverage, cumbersome administrative procedures specific to asylum seekers, and long wait times. Feelings of marginalization and insecurity associated with precarious migratory status appeared to amplify the effects of these barriers to care such that even a minor access difficulty could have dramatic effects on future help-seeking and access outcomes. Demonstrating awareness of public discourses interrogating their deservingness of health coverage, participants often interpreted access difficulties as evidence of health professionals' unwillingness to serve them. Such interpretations conspired with fears associated with the asylum claim process to suppress self-advocacy, further help-seeking, and at times even information-seeking. This finding is particularly significant in that it suggests a mechanism through which hostile public representations of forced migrants-increasingly prevalent in Western host countries-can themselves endanger the physical, psychological, and social health of highly disadvantaged populations, even in the presence of strong entitlement policies

    2016-01-01

    Full Text Available Wireless Sensor Network (WSN is known to be a highly resource constrained class of network where energy consumption is one of the prime concerns. In this research, a cross layer design methodology was adopted to design an energy efficient routing protocol entitled “Position Responsive Routing Protocol” (PRRP. PRRP is designed to minimize energy consumed in each node by (1 reducing the amount of time in which a sensor node is in an idle listening state and (2 reducing the average communication distance over the network. The performance of the proposed PRRP was critically evaluated in the context of network lifetime, throughput, and energy consumption of the network per individual basis and per data packet basis. The research results were analyzed and benchmarked against the well-known LEACH and CELRP protocols. The outcomes show a significant improvement in the WSN in terms of energy efficiency and the overall performance of WSN.

  15. Modeling Marine Electromagnetic Survey with Radial Basis Function Networks

    2014-11-01

    Full Text Available A marine electromagnetic survey is an engineering endeavour to discover the location and dimension of a hydrocarbon layer under an ocean floor. In this kind of survey, an array of electric and magnetic receivers are located on the sea floor and record the scattered, refracted and reflected electromagnetic wave, which has been transmitted by an electric dipole antenna towed by a vessel. The data recorded in receivers must be processed and further analysed to estimate the hydrocarbon location and dimension. To conduct those analyses successfuly, a radial basis function (RBF network could be employed to become a forward model of the input-output relationship of the data from a marine electromagnetic survey. This type of neural networks is working based on distances between its inputs and predetermined centres of some basis functions. A previous research had been conducted to model the same marine electromagnetic survey using another type of neural networks, which is a multi layer perceptron (MLP network. By comparing their validation and training performances (mean-squared errors and correlation coefficients, it is concluded that, in this case, the MLP network is comparatively better than the RBF network[1].[1] This manuscript is an extended version of our previous paper, entitled Radial Basis Function Networks for Modeling Marine Electromagnetic Survey, which had been presented on 2011 International Conference on Electrical Engineering and Informatics, 17-19 July 2011, Bandung, Indonesia.

This model is then augmented by adding a dynamic model for a multiplexor at an access node where the TB exercises a policing function. In the model, traffic policing, multiplexing and network utilization are formally defined. Based on the model, we study such issues as (quality of service QoS, traffic sizing and network dimensioning. Also we propose an algorithm using feedback control to improve QoS and network utilization. Applying MPEG video traces as the input traffic to the model, we verify the usefulness and effectiveness of our model.

    In the last decade we have seen the emergence of a new inter-disciplinary field focusing on the understanding of networks which are dynamic, large, open, and have a structure sometimes called random-biased. The field of Complex Networks is helping us better understand many complex phenomena such as the spread of  deseases, protein interactions, social relationships, to name but a few. Studies in Complex Networks are gaining attention due to some major scientific breakthroughs proposed by network scientists helping us understand and model interactions contained in large datasets. In fact, if we could point to one event leading to the widespread use of complex network analysis is the availability of online databases. Theories of Random Graphs from Erdös and Rényi from the late 1950s led us to believe that most networks had random characteristics. The work on large online datasets told us otherwise. Starting with the work of Barabási and Albert as well as Watts and Strogatz in the late 1990s, we now know th...

    The engineering problems of constructing autonomous networks of sensors and data processors that can provide alerts for dangerous situations provide a new context for debating the question whether man-made systems can emulate the cognitive capabilities of the mammalian brain. In this paper we consider the question whether a distributed network of sensors and data processors can form ``perceptions`` based on sensory data. Because sensory data can have exponentially many explanations, the use of a central data processor to analyze the outputs from a large ensemble of sensors will in general introduce unacceptable latencies for responding to dangerous situations. A better idea is to use a distributed ``Helmholtz machine`` architecture in which the sensors are connected to a network of simple processors, and the collective state of the network as a whole provides an explanation for the sensory data. In general communication within such a network will require time division multiplexing, which opens the door to the possibility that with certain refinements to the Helmholtz machine architecture it may be possible to build sensor networks that exhibit a form of artificial consciousness.

    What is "digital telephony"? To the authors, the term digital telephony denotes the technology used to provide a completely digital telecommunication system from end-to-end. This implies the use of digital technology from one end instru­ ment through transmission facilities and switching centers to another end instru­ ment. Digital telephony has become possible only because of the recent and on­ going surge of semiconductor developments, allowing microminiaturization and high reliability along with reduced costs. This book deals with both the future and the present. Thus, the first chapter is entitled, "A Network in Transition." As baselines, Chapters 2 and 11 provide the reader with the present status of teler-hone technology in terms of voice digiti­ zation as well as switching principles. The book is an outgrowth of the authors' consulting and teaching experience in the field since the early 1980s. The book has been written to provide both the engineering student and the practicing engineer a working k...

    Communication between and within brain regions is essential for information processing within functional networks. The current methods to determine the influence of one region on another are either based on temporal resolution, or require a predefined model for the connectivity direction. However these requirements are not always achieved, especially in fMRI studies, which have poor temporal resolution. We thus propose a new graph theory approach that focuses on the correlation influence between selected brain regions, entitled Dependency Network Analysis (DEPNA). Partial correlations are used to quantify the level of influence of each node during task performance. As a proof of concept, we conducted the DEPNA on simulated datasets and on two empirical motor and working memory fMRI tasks. The simulations revealed that the DEPNA correctly captures the network's hierarchy of influence. Applying DEPNA to the functional tasks reveals the dynamics between specific nodes as would be expected from prior knowledge. To conclude, we demonstrate that DEPNA can capture the most influencing nodes in the network, as they emerge during specific cognitive processes. This ability opens a new horizon for example in delineating critical nodes for specific clinical interventions.

    On Sunday 12 June 2005, a site-wide security software upgrade will be performed on all CERN network equipment. This maintenance operation will cause at least 2 short network interruptions of 2 minutes on each equipment item. There are hundreds of such items across the CERN site (Meyrin, Prévessin and all SPS and LHC pits), and it will thus take the whole day to treat them all. All network users and services will be affected. Central batch computing services will be interrupted during this period, expected to last from 8 a.m. until late evening. Job submission will still be possible but no jobs will actually be run. It is hoped to complete the computer centre upgrades in the morning so that stable access can be restored to lxplus, afs and nice services as soon as possible; this cannot be guaranteed, however. The opportunity will be used to interrupt and perform upgrades on the CERN Document Servers.

    2017-07-04

    Nuclear lamins are intermediate filament proteins that represent important structural components of metazoan nuclear envelopes (NEs). By combining proteomics and superresolution microscopy, we recently reported that both A- and B-type nuclear lamins form spatially distinct filament networks at the nuclear periphery of mouse fibroblasts. In particular, A-type lamins exhibit differential association with nuclear pore complexes (NPCs). Our studies reveal that the nuclear lamina network in mammalian somatic cells is less ordered and more complex than that of amphibian oocytes, the only other system in which the lamina has been visualized at high resolution. In addition, the NPC component Tpr likely links NPCs to the A-type lamin network, an association that appears to be regulated by C-terminal modification of various A-type lamin isoforms. Many questions remain, however, concerning the structure and assembly of lamin filaments, as well as with their mode of association with other nuclear components such as peripheral chromatin.

    Rugby league is a popular participation sport, but there have been concerns raised regarding the possible high number of severe neck, back and spine injuries. Therefore an epidemiological overview of rugby league neck, back and spine injuries and associated costs of these injuries was undertaken in one country over nine years. The New Zealand national Accident Compensation Corporation data for moderate to serious injury entitlement claims (MSC) over nine years were analysed for the number, type and cost of neck, back and spine rugby league injuries resulting in medical treatment. There were 206 (3%) neck, back and spine MSC claims totalling NZD$1,585,927 (4%) of the total injury entitlement costs for rugby league over the nine-year period. The rate of MSC neck, back and spine rugby league injuries was 26 per 1000 total rugby league claims. Although the rate of neck, back and spine injuries varied over the nine years from 22 to 40 per 1000 injury claims, there was a significant increase over the duration of the study in the number of neck, back and spine MSC claims (χ2=849, df=8, p<0.001), and the cost per MSC injury claim (χ2=19,054, df=8, p<0.001). The frequency, severity and first 12 months cost of neck, back and spine injuries in rugby league is an issue that needs to be addressed. Unfortunately the ACC data base does not provide information on how or why the injuries occurred. A prospective injury epidemiology study needs to be conducted that will allow collection of information surrounding the mechanisms of injury and possible causative risk factors such as tackling technique. In the meantime it is suggested that coaches should ensure tackling technique is correctly taught to all rugby league players to reduce the risk of neck, back and spine injury. Team medical personnel should be trained in dealing with neck and spine injuries as well as head related injuries, and emergency procedures in dealing with players with a suspected neck or back injury should be

    Health policy and education directives emphasise the need to involve service users and carers in healthcare, from service design and delivery to the education of healthcare professionals. This paper describes a pilot project aimed at eliciting teenagers and young people with cancer views in relation to the content of a continuing professional development module entitled 'adolescents with cancer'. Seven young people participated in the project. The project design was based on the PARTICIPATION - spice it up [Shephard, C., Treseder, P., 2002. spice it up! Dynamix, Swansea] framework, which aims to ensure effective and appropriate involvement of service users and carers. 'Post-it ideas storm' 'diamond ranking' and 'dot voting' were used to elicit the young people's views. The teenagers and young people could clearly articulate the qualities they felt nurses should have when caring for adolescents with cancer. They also identified topics they felt were important to include in the module, with an understanding of, and using, humour being given the highest priority. This was not originally included in the module timetable but as a direct result of consulting with the young people changes were made to reflect their views.

    We introduce the construction of a new framework for probing discrete emergent geometry and boundary-boundary observables based on a fundamentally a-dimensional underlying network structure. Using a gravitationally motivated action with Forman weighted combinatorial curvatures and simplicial volumes relying on a decomposition of an abstract simplicial complex into realized embeddings of proper skeletons, we demonstrate properties such as a minimal volume-scale cutoff, the necessity of a term playing the role of a positive definite cosmological constant as a regulator for nondegenerate geometries, and naturally emergent simplicial structures from Metropolis network evolution simulations with no restrictions on attachment rules or regular building blocks. We see emergent properties which echo results from both the spinfoam formalism and causal dynamical triangulations in quantum gravity, and provide analytical and numerical results to support the analogy. We conclude with a summary of open questions and intent for future work in developing the program.

    Citation between papers can be treated as a causal relationship. In addition, some citation networks have a number of similarities to the causal networks in network cosmology, e.g., the similar in-and out-degree distributions. Hence, it is possible to model the citation network using network cosmology. The casual network models built on homogenous spacetimes have some restrictions when describing some phenomena in citation networks, e.g., the hot papers receive more citations than other simultaneously published papers. We propose an inhomogenous causal network model to model the citation network, the connection mechanism of which well expresses some features of citation. The node growth trend and degree distributions of the generated networks also fit those of some citation networks well.

    Open innovation in networks has been a popular topic for long, this paper rethinks the concepts of innovation network and network organization, and clarifies the differences between them based on the network perspective. Network perspective means that: network is the context of firms; market...... and hierarchy can be analyzed from a network approach. Within a network perspective, there are different levels of network, and a firm may not always has the power to “manage” innovation networks due to different levels of power. Based on the strength of a firm’s power, its role may varies from manager...

    Utz, Sonja; Tanis, Martin; Vermeulen, Ivar

    2012-01-01

    Prior research on predictors of social network site (SNS) use has mainly focused on the Big Five, narcissism, and self-esteem. Results have been inconsistent, and variance explained was rather low. Need for popularity (NfP) might be a better predictor of SNS use, because SNSs are ideal venues for people with a high NfP. Study 1 tested NfP, self-esteem, need to belong, entitlement, and vanity as predictors for a range of SNS behaviors; Study 2 replaced entitlement and vanity with narcissism and added the Big Five as predictors. SNS behaviors assessed were grooming, strategic self-presentation, profile enhancement, disclosure of feelings, routine use of SNS, and number of friends. Results showed that NfP was the strongest and most consistent predictor of SNS behaviors. This pattern indicates that NfP plays an important role in SNSs.

  18. Understanding the control of acyl flux through the lipid metabolic network of plant oil biosynthesis.

    Science.gov (United States)

    Bates, Philip D

    2016-09-01

    Plant oil biosynthesis involves a complex metabolic network with multiple subcellular compartments, parallel pathways, cycles, and pathways that have a dual function to produce essential membrane lipids and triacylglycerol. Modern molecular biology techniques provide tools to alter plant oil compositions through bioengineering, however with few exceptions the final composition of triacylglycerol cannot be predicted. One reason for limited success in oilseed bioengineering is the inadequate understanding of how to control the flux of fatty acids through various fatty acid modification, and triacylglycerol assembly pathways of the lipid metabolic network. This review focuses on the mechanisms of acyl flux through the lipid metabolic network, and highlights where uncertainty resides in our understanding of seed oil biosynthesis.

  1. Animal transportation networks

    Perna, Andrea; Latty, Tanya

    2014-01-01

    Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research. PMID:25165598

    2010-01-01

    A noisy network coding scheme for sending multiple sources over a general noisy network is presented. For multi-source multicast networks, the scheme naturally extends both network coding over noiseless networks by Ahlswede, Cai, Li, and Yeung, and compress-forward coding for the relay channel by Cover and El Gamal to general discrete memoryless and Gaussian networks. The scheme also recovers as special cases the results on coding for wireless relay networks and deterministic networks by Avestimehr, Diggavi, and Tse, and coding for wireless erasure networks by Dana, Gowaikar, Palanki, Hassibi, and Effros. The scheme involves message repetition coding, relay signal compression, and simultaneous decoding. Unlike previous compress--forward schemes, where independent messages are sent over multiple blocks, the same message is sent multiple times using independent codebooks as in the network coding scheme for cyclic networks. Furthermore, the relays do not use Wyner--Ziv binning as in previous compress-forward sch...

    Despite evidence that large professional networks afford a host of financial and professional benefits, people vary in how motivated they are to build such networks. To help explain this variance, the present article moves beyond a rational self-interest account to examine the possibility that identity shapes individuals' intentions to network. Study 1 established a positive association between viewing professional networking as identity-congruent and the tendency to prioritize strengthening and expanding one's professional network. Study 2 revealed that manipulating the salience of the self affects networking intentions, but only among those high in networking identity-congruence. Study 3 further established causality by experimentally manipulating identity-congruence to increase networking intentions. Study 4 examined whether identity or self-interest is a better predictor of networking intentions, providing support for the former. These findings indicate that identity influences the networks people develop. Implications for research on the self, identity-based motivation, and professional networking are discussed.

    Populations are seldom completely isolated from their environment. Individuals in a particular geographic or social region may be considered a distinct network due to strong local ties but will also interact with individuals in other networks. We study the susceptible-infected-recovered process on interconnected network systems and find two distinct regimes. In strongly coupled network systems, epidemics occur simultaneously across the entire system at a critical infection strength βc, below which the disease does not spread. In contrast, in weakly coupled network systems, a mixed phase exists below βc of the coupled network system, where an epidemic occurs in one network but does not spread to the coupled network. We derive an expression for the network and disease parameters that allow this mixed phase and verify it numerically. Public health implications of communities comprising these two classes of network systems are also mentioned.

    Energy Technology Data Exchange (ETDEWEB)

    Ritter, G.X.; Sussner, P. [Univ. of Florida, Gainesville, FL (United States)

    1996-12-31

    The theory of artificial neural networks has been successfully applied to a wide variety of pattern recognition problems. In this theory, the first step in computing the next state of a neuron or in performing the next layer neural network computation involves the linear operation of multiplying neural values by their synaptic strengths and adding the results. Thresholding usually follows the linear operation in order to provide for nonlinearity of the network. In this paper we introduce a novel class of neural networks, called morphological neural networks, in which the operations of multiplication and addition are replaced by addition and maximum (or minimum), respectively. By taking the maximum (or minimum) of sums instead of the sum of products, morphological network computation is nonlinear before thresholding. As a consequence, the properties of morphological neural networks are drastically different than those of traditional neural network models. In this paper we consider some of these differences and provide some particular examples of morphological neural network.

  11. The many tunes of perisomatic targeting interneurons in the hippocampal network

    Directory of Open Access Journals (Sweden)

    Tommas J Ellender

    2010-07-01

    Full Text Available The axonal targets of perisomatic targeting interneurons make them ideally suited to synchronise excitatory neurons. As such they have been implicated in rhythm generation of network activity in many brain regions including the hippocampus. However, several recent publications indicate that their roles extend beyond that of rhythm generation. Firstly, it has been shown that, in addition to rhythm generation, GABAergic perisomatic inhibition also serves as a current generator contributing significantly to hippocampal oscillatory EEG signals. Furthermore, GABAergic interneurons have a hitherto unexpected role in the initiation of hippocampal population bursts, both in the developing and adult hippocampus. In this review, we describe these new observations in detail and discuss the implications they have for our understanding of the mechanisms underlying physiological and pathological hippocampal network activities. This review is part of the Frontiers in Cellular Neuroscience's special topic entitled GABA signalling in health and disease based on the meeting at the CNCR Amsterdam.

    In this work, the methods used in pinch design were applied to a heat exchanger network with the aid of an improved problem algorithm table. This table enables one to compose composite and grand composite curves in a simplified way. A user friendly computer code entitled DarboTEK, compiled by using Visual Basic 3.0, was developed for the design of integrated heat exchanger networks and estimation of related capital costs. Based on the data obtained from the TUPRAS petroleum refinery at Izmit, a retrofit design of heat exchanger networks was accomplished using DarboTEK. An investment of 3,576,627 dollars is needed which will be paid back in 1.69 years simply by energy conservation due to heat integration. (Author)

    Complex bufferless networks such as on-chip networks and optical burst switching networks haven't been paid enough attention in network science. In complex bufferless networks, the store and forward mechanism is not applicable, since the network nodes are not allowed to buffer data packets. In this paper, we study the data transmission process in complex bufferless networks from the perspective of network science. Specifically, we use the Price model to generate the underlying network topolog...

    2017-01-01

    This book covers recent developments in epidemic process models and related data on temporally varying networks. It is widely recognized that contact networks are indispensable for describing, understanding, and intervening to stop the spread of infectious diseases in human and animal populations; “network epidemiology” is an umbrella term to describe this research field. More recently, contact networks have been recognized as being highly dynamic. This observation, also supported by an increasing amount of new data, has led to research on temporal networks, a rapidly growing area. Changes in network structure are often informed by epidemic (or other) dynamics, in which case they are referred to as adaptive networks. This volume gathers contributions by prominent authors working in temporal and adaptive network epidemiology, a field essential to understanding infectious diseases in real society.

    The focus of this project was on the development of a "Network Service Plane" as an abstraction model for the control and provisioning of multi-layer networks. The primary motivation for this work were the requirements of next generation networked applications which will need to access advanced networking as a first class resource at the same level as compute and storage resources. A new class of "Intelligent Network Services" were defined in order to facilitate the integration of advanced network services into application specific workflows. This new class of network services are intended to enable real-time interaction between the application co-scheduling algorithms and the network for the purposes of workflow planning, real-time resource availability identification, scheduling, and provisioning actions.

    Maslennikov, O. V.; Nekorkin, V. I.

    2017-10-01

    Dynamical networks are systems of active elements (nodes) interacting with each other through links. Examples are power grids, neural structures, coupled chemical oscillators, and communications networks, all of which are characterized by a networked structure and intrinsic dynamics of their interacting components. If the coupling structure of a dynamical network can change over time due to nodal dynamics, then such a system is called an adaptive dynamical network. The term ‘adaptive’ implies that the coupling topology can be rewired; the term ‘dynamical’ implies the presence of internal node and link dynamics. The main results of research on adaptive dynamical networks are reviewed. Key notions and definitions of the theory of complex networks are given, and major collective effects that emerge in adaptive dynamical networks are described.

    Class network routing is implemented in a network such as a computer network comprising a plurality of parallel compute processors at nodes thereof. Class network routing allows a compute processor to broadcast a message to a range (one or more) of other compute processors in the computer network, such as processors in a column or a row. Normally this type of operation requires a separate message to be sent to each processor. With class network routing pursuant to the invention, a single message is sufficient, which generally reduces the total number of messages in the network as well as the latency to do a broadcast. Class network routing is also applied to dense matrix inversion algorithms on distributed memory parallel supercomputers with hardware class function (multicast) capability. This is achieved by exploiting the fact that the communication patterns of dense matrix inversion can be served by hardware class functions, which results in faster execution times.

    2014-11-06

    Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research. © 2014 The Author(s) Published by the Royal Society. All rights reserved.

    CERN Document Server

    Souza-e-Silva, Hallan

    2012-01-01

    Some years ago a cellular automata model was proposed to describe the evolution of the immune repertoire of B cells and antibodies based on Jerne's immune network theory and shape-space formalism. Here we investigate if the networks generated by this model in the different regimes can be classified as complex networks. We have found that in the chaotic regime the network has random characteristics with large, constant values of clustering coefficients, while in the ordered phase, the degree distribution of the network is exponential and the clustering coefficient exhibits power law behavior. In the transition region we observed a mixed behavior (random-like and exponential) of the degree distribution as opposed to the scale-free behavior reported for other biological networks. Randomness and low connectivity in the active sites allow for rapid changes in the connectivity distribution of the immune network in order to include and/or discard information and generate a dynamic memory. However it is the availabil...

  3. Dominating biological networks.

    Directory of Open Access Journals (Sweden)

    Tijana Milenković

    Full Text Available Proteins are essential macromolecules of life that carry out most cellular processes. Since proteins aggregate to perform function, and since protein-protein interaction (PPI networks model these aggregations, one would expect to uncover new biology from PPI network topology. Hence, using PPI networks to predict protein function and role of protein pathways in disease has received attention. A debate remains open about whether network properties of "biologically central (BC" genes (i.e., their protein products, such as those involved in aging, cancer, infectious diseases, or signaling and drug-targeted pathways, exhibit some topological centrality compared to the rest of the proteins in the human PPI network.To help resolve this debate, we design new network-based approaches and apply them to get new insight into biological function and disease. We hypothesize that BC genes have a topologically central (TC role in the human PPI network. We propose two different concepts of topological centrality. We design a new centrality measure to capture complex wirings of proteins in the network that identifies as TC those proteins that reside in dense extended network neighborhoods. Also, we use the notion of domination and find dominating sets (DSs in the PPI network, i.e., sets of proteins such that every protein is either in the DS or is a neighbor of the DS. Clearly, a DS has a TC role, as it enables efficient communication between different network parts. We find statistically significant enrichment in BC genes of TC nodes and outperform the existing methods indicating that genes involved in key biological processes occupy topologically complex and dense regions of the network and correspond to its "spine" that connects all other network parts and can thus pass cellular signals efficiently throughout the network. To our knowledge, this is the first study that explores domination in the context of PPI networks.

  4. Robustness of weighted networks

    Science.gov (United States)

    Bellingeri, Michele; Cassi, Davide

    2018-01-01

    Complex network response to node loss is a central question in different fields of network science because node failure can cause the fragmentation of the network, thus compromising the system functioning. Previous studies considered binary networks where the intensity (weight) of the links is not accounted for, i.e. a link is either present or absent. However, in real-world networks the weights of connections, and thus their importance for network functioning, can be widely different. Here, we analyzed the response of real-world and model networks to node loss accounting for link intensity and the weighted structure of the network. We used both classic binary node properties and network functioning measure, introduced a weighted rank for node importance (node strength), and used a measure for network functioning that accounts for the weight of the links (weighted efficiency). We find that: (i) the efficiency of the attack strategies changed using binary or weighted network functioning measures, both for real-world or model networks; (ii) in some cases, removing nodes according to weighted rank produced the highest damage when functioning was measured by the weighted efficiency; (iii) adopting weighted measure for the network damage changed the efficacy of the attack strategy with respect the binary analyses. Our results show that if the weighted structure of complex networks is not taken into account, this may produce misleading models to forecast the system response to node failure, i.e. consider binary links may not unveil the real damage induced in the system. Last, once weighted measures are introduced, in order to discover the best attack strategy, it is important to analyze the network response to node loss using nodes rank accounting the intensity of the links to the node.

  7. Learning conditional Gaussian networks

    DEFF Research Database (Denmark)

    Bøttcher, Susanne Gammelgaard

    This paper considers conditional Gaussian networks. The parameters in the network are learned by using conjugate Bayesian analysis. As conjugate local priors, we apply the Dirichlet distribution for discrete variables and the Gaussian-inverse gamma distribution for continuous variables, given...... a configuration of the discrete parents. We assume parameter independence and complete data. Further, to learn the structure of the network, the network score is deduced. We then develop a local master prior procedure, for deriving parameter priors in these networks. This procedure satisfies parameter...... independence, parameter modularity and likelihood equivalence. Bayes factors to be used in model search are introduced. Finally the methods derived are illustrated by a simple example....

    Networking is an infrastructure technology; it is a tool for NASA to support its space and aeronautics missions. Some of NASA's networking problems are shared by the commercial and/or military communities, and can be solved by working with these communities. However, some of NASA's networking problems are unique and will not be addressed by these other communities. Individual characteristics of NASA's space-mission networking enviroment are examined, the combination of all these characteristics that distinguish NASA's networking systems from either commercial or military systems is explained, and some research areas that are important for NASA to pursue are outlined.

    Networks of interconnected nodes have long played a key role in cognitive science, from artificial neural networks to spreading activation models of semantic memory. Recently, however, a new Network Science has been developed, providing insights into the emergence of global, system-scale properties in contexts as diverse as the Internet, metabolic reactions or collaborations among scientists. Today, the inclusion of network theory into cognitive sciences, and the expansion of complex systems science, promises to significantly change the way in which the organization and dynamics of cognitive and behavioral processes are understood. In this paper, we review recent contributions of network theory at different levels and domains within the cognitive sciences.

    Complex social networks have received increasing attention from researchers. Recent work has focused on mechanisms that produce scale-free networks. We theoretically and empirically characterize the buyer–supplier network of the US economy and find that purely scale-free models have trouble matching key attributes of the network. We construct an alternative model that incorporates realistic features of firms’ buyer–supplier relationships and estimate the model’s parameters using microdata on firms’ self-reported customers. This alternative framework is better able to match the attributes of the actual economic network and aids in further understanding several important economic phenomena. PMID:21402924

    Networks are mathematical structures that are universally used to describe a large variety of complex systems such as the brain or the Internet. Characterizing the geometrical properties of these networks has become increasingly relevant for routing problems, inference and data mining. In real growing networks, topological, structural and geometrical properties emerge spontaneously from their dynamical rules. Nevertheless we still miss a model in which networks develop an emergent complex geometry. Here we show that a single two parameter network model, the growing geometrical network, can generate complex network geometries with non-trivial distribution of curvatures, combining exponential growth and small-world properties with finite spectral dimensionality. In one limit, the non-equilibrium dynamical rules of these networks can generate scale-free networks with clustering and communities, in another limit planar random geometries with non-trivial modularity. Finally we find that these properties of the geometrical growing networks are present in a large set of real networks describing biological, social and technological systems.

  18. The regulation of social recognition, social communication and aggression: vasopressin in the social behavior neural network.

    Albers, H Elliott

    2012-03-01

    Neuropeptides in the arginine vasotocin/arginine vasopressin (AVT/AVP) family play a major role in the regulation of social behavior by their actions in the brain. In mammals, AVP is found within a circuit of recriprocally connected limbic structures that form the social behavior neural network. This review examines the role played by AVP within this network in controlling social processes that are critical for the formation and maintenance of social relationships: social recognition, social communication and aggression. Studies in a number of mammalian species indicate that AVP and AVP V1a receptors are ideally suited to regulate the expression of social processes because of their plasticity in response to factors that influence social behavior. The pattern of AVP innervation and V1a receptors across the social behavior neural network may determine the potential range and intensity of social responses that individuals display in different social situations. Although fundamental information on how social behavior is wired in the brain is still lacking, it is clear that different social behaviors can be influenced by the actions of AVP in the same region of the network and that AVP can act within multiple regions of this network to regulate the expression of individual social behaviors. The existing data suggest that AVP can influence social behavior by modulating the interpretation of sensory information, by influencing decision making and by triggering complex motor outputs.

    2017-06-01

    Full Text Available Intercommunication of Dopamine Receptors (DRs with their associate protein partners is crucial to maintain regular brain function in human. Majority of the brain disorders arise due to malfunctioning of such communication process. Hence, contributions of genetic factors, as well as phenotypic indications for various neurological and psychiatric disorders are often attributed as sharing in nature. In our earlier research article entitled “Human Dopamine Receptors Interaction Network (DRIN: a systems biology perspective on topology, stability and functionality of the network” (Podder et al., 2014 [1], we had depicted a holistic interaction map of human Dopamine Receptors. Given emphasis on the topological parameters, we had characterized the functionality along with the vulnerable properties of the network. In support of this, we hereby provide an additional data highlighting the genetic overlapping of various brain disorders in the network. The data indicates the sharing nature of disease genes for various neurological and psychiatric disorders in dopamine receptors connecting protein-protein interactions network. The data also indicates toward an alternative approach to prioritize proteins for overlapping brain disorders as valuable drug targets in the network.

    2008-01-01

    Emerging high-bandwidth, low-latency network technology has made network-based architectures both feasible and potentially desirable for use in satellite payload architectures. The selection of network topology is a critical component when developing these multi-node or multi-point architectures. This study examines network topologies and their effect on overall network performance. Numerous topologies were reviewed against a number of performance, reliability, and cost metrics. This document identifies a handful of good network topologies for satellite applications and the metrics used to justify them as such. Since often multiple topologies will meet the requirements of the satellite payload architecture under development, the choice of network topology is not easy, and in the end the choice of topology is influenced by both the design characteristics and requirements of the overall system and the experience of the developer.

    2016-02-23

    A network mapper for performing tasks on targets is provided. The mapper generates a map of a network that specifies the overall configuration of the network. The mapper inputs a procedure that defines how the network is to be mapped. The procedure specifies what, when, and in what order the tasks are to be performed. Each task specifies processing that is to be performed for a target to produce results. The procedure may also specify input parameters for a task. The mapper inputs initial targets that specify a range of network addresses to be mapped. The mapper maps the network by, for each target, executing the procedure to perform the tasks on the target. The results of the tasks represent the mapping of the network defined by the initial targets.

    Networks have played a critical role in high-energy physics (HEP), enabling us to access and effectively utilize globally distributed resources to meet the needs of our physicists. Because of their importance in enabling our grid computing infrastructure many physicists have taken leading roles in research and education (R&E) networking, participating in, and even convening, network related meetings and research programs with the broader networking community worldwide. This has led to HEP benefiting from excellent global networking capabilities for little to no direct cost. However, as other science domains ramp-up their need for similar networking it becomes less clear that this situation will continue unchanged. What this means for ATLAS in particular needs to be understood. ATLAS has evolved its computing model since the LHC started based upon its experience with using globally distributed resources. The most significant theme of those changes has been increased reliance upon, and use of, its networks....

  8. Organization of complex networks

    Kitsak, Maksim

    Many large complex systems can be successfully analyzed using the language of graphs and networks. Interactions between the objects in a network are treated as links connecting nodes. This approach to understanding the structure of networks is an important step toward understanding the way corresponding complex systems function. Using the tools of statistical physics, we analyze the structure of networks as they are found in complex systems such as the Internet, the World Wide Web, and numerous industrial and social networks. In the first chapter we apply the concept of self-similarity to the study of transport properties in complex networks. Self-similar or fractal networks, unlike non-fractal networks, exhibit similarity on a range of scales. We find that these fractal networks have transport properties that differ from those of non-fractal networks. In non-fractal networks, transport flows primarily through the hubs. In fractal networks, the self-similar structure requires any transport to also flow through nodes that have only a few connections. We also study, in models and in real networks, the crossover from fractal to non-fractal networks that occurs when a small number of random interactions are added by means of scaling techniques. In the second chapter we use k-core techniques to study dynamic processes in networks. The k-core of a network is the network's largest component that, within itself, exhibits all nodes with at least k connections. We use this k-core analysis to estimate the relative leadership positions of firms in the Life Science (LS) and Information and Communication Technology (ICT) sectors of industry. We study the differences in the k-core structure between the LS and the ICT sectors. We find that the lead segment (highest k-core) of the LS sector, unlike that of the ICT sector, is remarkably stable over time: once a particular firm enters the lead segment, it is likely to remain there for many years. In the third chapter we study how

    The NASA Research Opportunities in Space and Earth Science (ROSES) program is supporting a wireless sensor network project as part of its Advanced Information Systems Technology "Smart Sensor Web" initiative. The project, entitled Seamonster (for SouthEast Alaska MONitoring Network for Science, Telecomm, and Education Research) is led by the University of Alaska Southeast (Juneau) in collaboration with Microsoft- Vexcel in Boulder Colorado. This paper describes the Education Research component of Seamonster with emphasis on live scientist connection to educators, field experience, and inquiry-based student learning opportunity. Part of the Seamonster science will focus on a succession of valleys near Juneau in various stages of deglaciation, in effect providing a synopsis of a millennium-timescale process in a single moment. The Seamonster sensor configuration is designed to initially focus on a single watershed--Lemon Creek--and to subsequently expand to this larger region of interest. The aim is to provide data that narrates the story of watershed processes in real time, for example connecting precipitation to outflow volume and turbidity throughout the course of the year. As the project grows in scope the educational component will expand to keep pace. Having educators and by extension their students connected to data-driven stories as they unfold is a major objective of the project and will represent a milestone in efforts to include more people in front-end science as it happens.

    2005-06-01

    Call for Papers: Optical Access Networks With the wide deployment of fiber-optic technology over the past two decades, we have witnessed a tremendous growth of bandwidth capacity in the backbone networks of today's telecommunications infrastructure. However, access networks, which cover the "last-mile" areas and serve numerous residential and small business users, have not been scaled up commensurately. The local subscriber lines for telephone and cable television are still using twisted pairs and coaxial cables. Most residential connections to the Internet are still through dial-up modems operating at a low speed on twisted pairs. As the demand for access bandwidth increases with emerging high-bandwidth applications, such as distance learning, high-definition television (HDTV), and video on demand (VoD), the last-mile access networks have become a bandwidth bottleneck in today's telecommunications infrastructure. To ease this bottleneck, it is imperative to provide sufficient bandwidth capacity in the access networks to open the bottleneck and thus present more opportunities for the provisioning of multiservices. Optical access solutions promise huge bandwidth to service providers and low-cost high-bandwidth services to end users and are therefore widely considered the technology of choice for next-generation access networks. To realize the vision of optical access networks, however, many key issues still need to be addressed, such as network architectures, signaling protocols, and implementation standards. The major challenges lie in the fact that an optical solution must be not only robust, scalable, and flexible, but also implemented at a low cost comparable to that of existing access solutions in order to increase the economic viability of many potential high-bandwidth applications. In recent years, optical access networks have been receiving tremendous attention from both academia and industry. A large number of research activities have been carried out or

    Directory of Open Access Journals (Sweden)

    Angel Garrido

    2011-01-01

    Full Text Available In this paper, we analyze a few interrelated concepts about graphs, such as their degree, entropy, or their symmetry/asymmetry levels. These concepts prove useful in the study of different types of Systems, and particularly, in the analysis of Complex Networks. A System can be defined as any set of components functioning together as a whole. A systemic point of view allows us to isolate a part of the world, and so, we can focus on those aspects that interact more closely than others. Network Science analyzes the interconnections among diverse networks from different domains: physics, engineering, biology, semantics, and so on. Current developments in the quantitative analysis of Complex Networks, based on graph theory, have been rapidly translated to studies of brain network organization. The brain's systems have complex network features—such as the small-world topology, highly connected hubs and modularity. These networks are not random. The topology of many different networks shows striking similarities, such as the scale-free structure, with the degree distribution following a Power Law. How can very different systems have the same underlying topological features? Modeling and characterizing these networks, looking for their governing laws, are the current lines of research. So, we will dedicate this Special Issue paper to show measures of symmetry in Complex Networks, and highlight their close relation with measures of information and entropy.

    2018-01-01

    The field of neuroscience is facing an unprecedented expanse in the volume and diversity of available data. Traditionally, network models have provided key insights into the structure and function of the brain. With the advent of big data in neuroscience, both more sophisticated models capable of characterizing the increasing complexity of the data and novel methods of quantitative analysis are needed. Recently, multilayer networks, a mathematical extension of traditional networks, have gained increasing popularity in neuroscience due to their ability to capture the full information of multi-model, multi-scale, spatiotemporal data sets. Here, we review multilayer networks and their applications in neuroscience, showing how incorporating the multilayer framework into network neuroscience analysis has uncovered previously hidden features of brain networks. We specifically highlight the use of multilayer networks to model disease, structure-function relationships, network evolution, and link multi-scale data. Finally, we close with a discussion of promising new directions of multilayer network neuroscience research and propose a modified definition of multilayer networks designed to unite and clarify the use of the multilayer formalism in describing real-world systems.

    Using a commercial software CD and minimal up-mass, SNFM monitors the Payload local area network (LAN) to analyze and troubleshoot LAN data traffic. Validating LAN traffic models may allow for faster and more reliable computer networks to sustain systems and science on future space missions. Research Summary: This experiment studies the function of the computer network onboard the ISS. On-orbit packet statistics are captured and used to validate ground based medium rate data link models and enhance the way that the local area network (LAN) is monitored. This information will allow monitoring and improvement in the data transfer capabilities of on-orbit computer networks. The Serial Network Flow Monitor (SNFM) experiment attempts to characterize the network equivalent of traffic jams on board ISS. The SNFM team is able to specifically target historical problem areas including the SAMS (Space Acceleration Measurement System) communication issues, data transmissions from the ISS to the ground teams, and multiple users on the network at the same time. By looking at how various users interact with each other on the network, conflicts can be identified and work can begin on solutions. SNFM is comprised of a commercial off the shelf software package that monitors packet traffic through the payload Ethernet LANs (local area networks) on board ISS.

  15. Local dependency in networks

    2015-06-01

    Full Text Available Many real world data and processes have a network structure and can usefully be represented as graphs. Network analysis focuses on the relations among the nodes exploring the properties of each network. We introduce a method for measuring the strength of the relationship between two nodes of a network and for their ranking. This method is applicable to all kinds of networks, including directed and weighted networks. The approach extracts dependency relations among the network’s nodes from the structure in local surroundings of individual nodes. For the tasks we deal with in this article, the key technical parameter is locality. Since only the surroundings of the examined nodes are used in computations, there is no need to analyze the entire network. This allows the application of our approach in the area of large-scale networks. We present several experiments using small networks as well as large-scale artificial and real world networks. The results of the experiments show high effectiveness due to the locality of our approach and also high quality node ranking comparable to PageRank.

    Complex problems in science, business, and engineering typically require some tradeoff between exploitation of known solutions and exploration for novel ones, where, in many cases, information about known solutions can also disseminate among individual problem solvers through formal or informal networks. Prior research on complex problem solving by collectives has found the counterintuitive result that inefficient networks, meaning networks that disseminate information relatively slowly, can perform better than efficient networks for problems that require extended exploration. In this paper, we report on a series of 256 Web-based experiments in which groups of 16 individuals collectively solved a complex problem and shared information through different communication networks. As expected, we found that collective exploration improved average success over independent exploration because good solutions could diffuse through the network. In contrast to prior work, however, we found that efficient networks outperformed inefficient networks, even in a problem space with qualitative properties thought to favor inefficient networks. We explain this result in terms of individual-level explore-exploit decisions, which we find were influenced by the network structure as well as by strategic considerations and the relative payoff between maxima. We conclude by discussing implications for real-world problem solving and possible extensions.

    The objective of this study was to use a qualitative approach to examine the perceptions of dentists who led a health promotion programme entitled "Baby Teeth DO Matter". Semi-structured interviews were undertaken with a variety of participants in a health promotional programme facilitated by a shadow Local Professional Network. These were then recorded and transcribed verbatim. The transcripts were line numbered and subjected to thematic analysis to develop a coding frame. Overarching themes were developed from the coded transcripts by organising them into clusters based on the similarity of their meaning and checked against the coded extracts and the raw data. General Dental Practice. General Dental Practitioners. A Greater Manchester-wide prevention programme entitled "Baby teeth DO Matter". To determine the perceptions of involved clinicians and whether "clinically owned and clinically led" services add value. Eight codes were generated: "Success of the project", "Down-stream to up-stream", "Importance of clinically led and clinically owned", "Keeping the approach simple", "Importance of networking", "Importance of Dental Public Health", "Importance of task and finish" and "Threats to the future of the Local Professional Network". These were organised into three over-arching themes. "Clinically Led and Clinically Owned" projects appear to empower local practitioners and add value. They encourage community-facing practitioners, build capacity and develop personal skills;--all in accordance with the fundamental principles of the Ottawa Charter. Distributed leadership was seen to be effective and Dental Public Health input, "Task and Finishing", resources and clarity of communication were all considered to be of critical importance.

  20. Green heterogeneous wireless networks

    CERN Document Server

    Ismail, Muhammad; Nee, Hans-Peter; Qaraqe, Khalid A; Serpedin, Erchin

    2016-01-01

    This book focuses on the emerging research topic "green (energy efficient) wireless networks" which has drawn huge attention recently from both academia and industry. This topic is highly motivated due to important environmental, financial, and quality-of-experience (QoE) considerations. Specifically, the high energy consumption of the wireless networks manifests in approximately 2% of all CO2 emissions worldwide. This book presents the authors’ visions and solutions for deployment of energy efficient (green) heterogeneous wireless communication networks. The book consists of three major parts. The first part provides an introduction to the "green networks" concept, the second part targets the green multi-homing resource allocation problem, and the third chapter presents a novel deployment of device-to-device (D2D) communications and its successful integration in Heterogeneous Networks (HetNets). The book is novel in that it specifically targets green networking in a heterogeneous wireless medium, which re...

    resources are limited. Hence, to counteract this trend, current QoS mechanisms must become simpler to deploy and operate, in order to motivate NSPs to employ QoS techniques instead of overprovisioning. Software Defined Networking (SDN) represents a paradigm shift in the way telecommunication and data...... networks are designed and managed. This thesis argues that SDN can greatly simplify QoS provisioning in communication networks, and even improve QoS in various ways. To this end, the impact of SDN on QoS is assessed from both a network performance perspective (e.g. bandwidth, delay), and also from a more...... generic perspective (e.g. service provisioning speed, resources availability). As a result, new mechanisms for providing QoS are proposed, solutions for SDN-specific QoS challenges are designed and tested, and new network management concepts are prototyped, all aiming to improve QoS for network services...

    2015-01-01

    This brief presents research results on social cognitive radio networks, a transformational and innovative networking paradigm that promotes the nexus between social interactions and cognitive radio networks. Along with a review of the research literature, the text examines the key motivation and challenges of social cognitive radio network design. Three socially inspired distributed spectrum sharing mechanisms are introduced: adaptive channel recommendation mechanism, imitation-based social spectrum sharing mechanism, and evolutionarily stable spectrum access mechanism. The brief concludes with a discussion of future research directions which ascertains that exploiting social interactions for distributed spectrum sharing will advance the state-of-the-art of cognitive radio network design, spur a new line of thinking for future wireless networks, and enable novel wireless service and applications.

    We review the current state of social communication between healthcare professionals, the role of consumer social networking, and some emerging technologies to address the gaps. In particular, the review covers (1) the current state of loose social networking for continuing medical education (CME) and other broadcast information dissemination; (2) social networking for business promotion; (3) social networking for peer collaboration, including simple communication as well as more robust data-centered collaboration around patient care; and (4) engaging patients on social platforms, including integrating consumer-originated data into the mix of healthcare data. We will see how, as the nature of healthcare delivery moves from the institution-centric way of tradition to a more social and networked ambulatory pattern that we see emerging today, the nature of health IT has also moved from enterprise-centric systems to more socially networked, cloud-based options.

    Vanderveen, Keith B [Tracy, CA; Talbot, Edward B [Livermore, CA; Mayer, Laurence E [Davis, CA

    2008-04-08

    Nodes in a network having a plurality of nodes establish communication links with other nodes using available transmission media, as the ability to establish such links becomes available and desirable. The nodes predict when existing communications links will fail, become overloaded or otherwise degrade network effectiveness and act to establish substitute or additional links before the node's ability to communicate with the other nodes on the network is adversely affected. A node stores network topology information and programmed link establishment rules and criteria. The node evaluates characteristics that predict existing links with other nodes becoming unavailable or degraded. The node then determines whether it can form a communication link with a substitute node, in order to maintain connectivity with the network. When changing its communication links, a node broadcasts that information to the network. Other nodes update their stored topology information and consider the updated topology when establishing new communications links for themselves.

    We use a clustering signature, based on a recently introduced generalization of the clustering coefficient to directed networks, to analyze 16 directed real-world networks of five different types: social networks, genetic transcription networks, word adjacency networks, food webs, and electric circuits. We show that these five classes of networks are cleanly separated in the space of clustering signatures due to the statistical properties of their local neighborhoods, demonstrating the usefulness of clustering signatures as a classifier of directed networks.

  11. Networks in ATLAS

    McKee, Shawn; ATLAS Collaboration

    2017-10-01

    Networks have played a critical role in high-energy physics (HEP), enabling us to access and effectively utilize globally distributed resources to meet the needs of our physicists. Because of their importance in enabling our grid computing infrastructure many physicists have taken leading roles in research and education (R&E) networking, participating in, and even convening, network related meetings and research programs with the broader networking community worldwide. This has led to HEP benefiting from excellent global networking capabilities for little to no direct cost. However, as other science domains ramp-up their need for similar networking it becomes less clear that this situation will continue unchanged. What this means for ATLAS in particular needs to be understood. ATLAS has evolved its computing model since the LHC started based upon its experience with using globally distributed resources. The most significant theme of those changes has been increased reliance upon, and use of, its networks. We will report on a number of networking initiatives in ATLAS including participation in the global perfSONAR network monitoring and measuring efforts of WLCG and OSG, the collaboration with the LHCOPN/LHCONE effort, the integration of network awareness into PanDA, the use of the evolving ATLAS analytics framework to better understand our networks and the changes in our DDM system to allow remote access to data. We will also discuss new efforts underway that are exploring the inclusion and use of software defined networks (SDN) and how ATLAS might benefit from: • Orchestration and optimization of distributed data access and data movement. • Better control of workflows, end to end. • Enabling prioritization of time-critical vs normal tasks • Improvements in the efficiency of resource usage

    In this work we present a model for evolving networks, where the driven force is related to the social affinity between individuals of a population. In the model, a set of individuals initially arranged on a regular ordered network and thus linked with their closest neighbors are allowed to rearrange their connections according to a dynamics closely related to that of the stable marriage problem. We show that the behavior of some topological properties of the resulting networks follows a non trivial pattern.

    This paper summarizes the research results on the friendly network robotics in fiscal 1996. This research assumes an android robot as an ultimate robot and the future robot system utilizing computer network technology. The robot aiming at human daily work activities in factories or under extreme environments is required to work under usual human work environments. The human robot with similar size, shape and functions to human being is desirable. Such robot having a head with two eyes, two ears and mouth can hold a conversation with human being, can walk with two legs by autonomous adaptive control, and has a behavior intelligence. Remote operation of such robot is also possible through high-speed computer network. As a key technology to use this robot under coexistence with human being, establishment of human coexistent robotics was studied. As network based robotics, use of robots connected with computer networks was also studied. In addition, the R-cube (R{sup 3}) plan (realtime remote control robot technology) was proposed. 82 refs., 86 figs., 12 tabs.

    Sun, Yong; Kurths, Jürgen; Zhan, Meng

    2017-08-01

    Power grids and their properties have been studied broadly in many aspects. In this paper, we propose a novel concept, power-flow-based power grid, as a typical power-functional network, based on the calculation of power flow distribution from power electrical engineering. We compare it with structural networks based on the shortest path length and effective networks based on the effective electrical distance and study the relationship among these three kinds of networks. We find that they have roughly positive correlations with each other, indicating that in general any close nodes in the topological structure are actually connected in function. However, we do observe some counter-examples that two close nodes in a structural network can have a long distance in a power-functional network, namely, two physically connected nodes can actually be separated in function. In addition, we find that power grids in the structural network tend to be heterogeneous, whereas those in the effective and power-functional networks tend to be homogeneous. These findings are expected to be significant not only for power grids but also for various other complex networks.

    2009-01-01

    The evolutionary history of a collection of species is usually represented by a phylogenetic tree. Sometimes, phylogenetic networks are used as a means of representing reticulate evolution or of showing uncertainty and incompatibilities in evolutionary datasets. This is often done using unrooted phylogenetic networks such as split networks, due in part, to the availability of software (SplitsTree) for their computation and visualization. In this paper we discuss the problem of drawing rooted phylogenetic networks as cladograms or phylograms in a number of different views that are commonly used for rooted trees. Implementations of the algorithms are available in new releases of the Dendroscope and SplitsTree programs.

    In this article, we propose a mixing navigation mechanism, which interpolates between random-walk and shortest-path protocol. The navigation efficiency can be remarkably enhanced via a few routers. Some advanced strategies are also designed: For non-geographical scale-free networks, the targeted strategy with a tiny fraction of routers can guarantee an efficient navigation with low and stable delivery time almost independent of network size. For geographical localized networks, the clustering strategy can simultaneously increase efficiency and reduce the communication cost. The present mixing navigation mechanism is of significance especially for information organization of wireless sensor networks and distributed autonomous robotic systems.

    The current Internet infrastructure is not able to support independent evolution and innovation at physical and network layer functionalities, protocols and services, while at same time supporting the increasing bandwidth demands of evolving and heterogeneous applications. This paper addresses this problem by proposing a completely democratized optical network infrastructure. It introduces the novel concepts of the optical white box and bare metal optical switch as key technology enablers for democratizing optical networks. These are programmable optical switches whose hardware is loosely connected internally and is completely separated from their control software. To alleviate their complexity, a multi-dimensional abstraction mechanism using software-defined network technology is proposed. It creates a universal model of the proposed switches without exposing their technological details. It also enables a conventional network programmer to develop network applications for control of the optical network without specific technical knowledge of the physical layer. Furthermore, a novel optical network virtualization mechanism is proposed, enabling the composition and operation of multiple coexisting and application-specific virtual optical networks sharing the same physical infrastructure. Finally, the optical white box and the abstraction mechanism are experimentally evaluated, while the virtualization mechanism is evaluated with simulation. © 2016 The Author(s).

The most basic issues are structural: how does one characterize the wiring diagram of a food web or the Internet or the metabolic network of the bacterium Escherichia coli? Are there any unifying principles underlying their topology? From the perspective of nonlinear dynamics, we would also like to understand how an enormous network of interacting dynamical systems-be they neurons, power stations or lasers-will behave collectively, given their individual dynamics and coupling architecture. Researchers are only now beginning to unravel the structure and dynamics of complex networks.

    To understand the factors that encourage the deployment of a new networking technology, we must be able to model how such technology gets deployed. We investigate how network structure influences deployment with a simple deployment model and different network models through computer simulations. The results indicate that a realistic model of networking technology deployment should take network structure into account.

  8. Forman curvature for directed networks

    Sreejith, R P; Saucan, Emil; Samal, Areejit

    2016-01-01

    A goal in network science is the geometrical characterization of complex networks. In this direction, we have recently introduced the Forman's discretization of Ricci curvature to the realm of undirected networks. Investigation of Forman curvature in diverse model and real-world undirected networks revealed that this measure captures several aspects of the organization of complex undirected networks. However, many important real-world networks are inherently directed in nature, and the Forman curvature for undirected networks is unsuitable for analysis of such directed networks. Hence, we here extend the Forman curvature for undirected networks to the case of directed networks. The simple mathematical formula for the Forman curvature in directed networks elegantly incorporates node weights, edge weights and edge direction. By applying the Forman curvature for directed networks to a variety of model and real-world directed networks, we show that the measure can be used to characterize the structure of complex ...

  14. KNOWLEDGE TRANSFER THROUGH NETWORKS

    2012-06-01

    Full Text Available Knowledge is a vital intangible asset for any organization and cannot be valued exactly due its special form of materialization. Although we have this drawback, a scientifically established value should be used in order to measure the performance of knowledge holders. A correct valuation helps to know the worth of assets offered in exploitation. Exploitation of this resource could be done in several different ways, but integration in knowledge networks seems to generate best efficiency ratio. Networks offer the possibility to change information, to obtain new information, to build further ideas arose from network partners or to develop together new ideas. Thus, networks assure conditions to optimize the members’ knowledge portfolios. Optimization of knowledge usage creates benefits for network members. These benefits could be profits (if members are private companies or social welfare (if members are looking after collective purposes. Taxonomy of knowledge networks is diverse, permitting an adaptation to the needs of members. Networks permit a large scale of heterogeneity. Since an important part of new knowledge creating costs is covered from public budgetary resources, a special development is recorded at those networks which are exclusively or partly organized in the public sector or benefit by participation from the public sector.

    Full Text Available This paper presents ongoing work on localization and positioning through triangulation procedure for a Fixed Sensors Network - FSN.The FSN has to work as a system.As the triangulation problem becomes high complicated in a case with large numbers of sensors and transmitters, an adequate grid topology is needed in order to tackle the detection complexity.For that reason a Network grid topology is presented and areas that are problematic and need further analysis are analyzed.The Network System in order to deal with problems of saturation and False Triangulations - FTRNs will have to find adequate methods in every sub-area of the Area Of Interest - AOI.Also, concepts like Sensor blindness and overall Network blindness, are presented. All these concepts affect the Network detection rate and its performance and ought to be considered in a way that the network overall performance won’t be degraded.Network performance should be monitored contentiously, with right algorithms and methods.It is also shown that as the number of TRNs and FTRNs is increased Detection Complexity - DC is increased.It is hoped that with further research all the characteristics of a triangulation system network for positioning will be gained and the system will be able to perform autonomously with a high detection rate.

  6. Network cities and externalities

    Directory of Open Access Journals (Sweden)

    Rafael Boix Domènech

    2004-01-01

    Full Text Available The concept of «agglomeration economies» explains the existence of advantages derived from the concentration of population and activity. However, it does not explain the existence of spatially dynamic external economies. Network economies generated in networks of cities correspond to this last type, since they are generated from the interaction between urban units, linked by a network relationship. The objective of this research is to advance in the study of the relationship between the networks of cities and the generation of external economies. The research is divided in four parts: first we expose the link between networks of cities and external economies. The second part outlines a model for the combined measuring of the concentration and network economies. The third part explains the results of applying the model to a case of study: the network of cities of Catalonia. The results suggest that there is a causal relationship between the organization of the urban units forming networks of cities and the generation of external economies that affect growth and economic development. Finally, conclusions and policy implications are drawn up.

    2007-06-01

    The interest in tourism has always been strong, for its important role in economic flows among nations. On this study we analyze the arrivals of international tourism (edges) over 206 countries and territories (nodes) around the world, on the year 2004. International tourist arrivals reached a record of 763 million in 2004. We characterize analytically the topological and weighted properties of the resulting network. International tourist arrivals are analyzed over in strength and out strength flows, resulting on a highly directed network, with a very heterogeneity of weights and strengths. The inclusion of edge weights and directions on the analysis of network architecture allows a more realistic insight on the structure of the networks. Centrality, assortativity and disparity are measured for the topological and weighted structure. Assortativity measures the tendency of having a high weight edges connecting two nodes with similar degrees. ITN is disassortative, opposite to social network. Disparity quantifies the how similar are the flows on a node neighborhood, measuring the heterogeneity of weights for in flows and out flows of tourism. These results provide an application of the recent methods of weighted and directed networks, showing that weights are relevant and that in general the modeling of complex networks must go beyond topology. The network structure may influence how tourism hubs, distribution of flows, and centralization can be explored on countries strategic positioning and policy making.

    Full Text Available A cross-cultural comparison of social networking structure on McDonald’s Facebook fan sites between Taiwan and the USA was conducted utilizing the individualism/collectivism dimension proposed by Hofstede. Four network indicators are used to describe the network structure of McDonald’s Facebook fan sites: size, density, clique and centralization. Individuals who post on both Facebook sites for the year of 2012 were considered as network participants for the purpose of the study. Due to the huge amount of data, only one thread of postings was sampled from each month of the year of 2012. The final data consists of 1002 postings written by 896 individuals and 5962 postings written by 5532 individuals from Taiwan and the USA respectively. The results indicated that the USA McDonald’s Facebook fan network has more fans, while Taiwan’s McDonald’s Facebook fan network is more densely connected. Cliques did form among the overall multiplex and within the individual uniplex networks in two countries, yet no significant differences were found between them. All the fan networks in both countries are relatively centralized, mostly on the site operators.

    A general framework for hybrids of hidden Markov models (HMMs) and neural networks (NNs) called hidden neural networks (HNNs) is described. The article begins by reviewing standard HMMs and estimation by conditional maximum likelihood, which is used by the HNN. In the HNN, the usual HMM probability...... parameters are replaced by the outputs of state-specific neural networks. As opposed to many other hybrids, the HNN is normalized globally and therefore has a valid probabilistic interpretation. All parameters in the HNN are estimated simultaneously according to the discriminative conditional maximum...... likelihood criterion. The HNN can be viewed as an undirected probabilistic independence network (a graphical model), where the neural networks provide a compact representation of the clique functions. An evaluation of the HNN on the task of recognizing broad phoneme classes in the TIMIT database shows clear...

    This book aims to bring together researchers and practitioners working across domains and research disciplines to measure, model, and visualize complex networks. It collects the works presented at the 9th International Conference on Complex Networks (CompleNet) 2018 in Boston, MA in March, 2018. With roots in physical, information and social science, the study of complex networks provides a formal set of mathematical methods, computational tools and theories to describe prescribe and predict dynamics and behaviors of complex systems. Despite their diversity, whether the systems are made up of physical, technological, informational, or social networks, they share many common organizing principles and thus can be studied with similar approaches. This book provides a view of the state-of-the-art in this dynamic field and covers topics such as group decision-making, brain and cellular connectivity, network controllability and resiliency, online activism, recommendation systems, and cyber security.

    Call for Papers: Optical Access Networks Guest Editors Jun Zheng, University of Ottawa Nirwan Ansari, New Jersey Institute of Technology Submission Deadline: 1 June 2005 h2>Backgroundh2> With the wide deployment of fiber-optic technology over the past two decades, we have witnessed a tremendous growth of bandwidth capacity in the backbone networks of today's telecommunications infrastructure. However, access networks, which cover the "last-mile" areas and serve numerous residential and small business users, have not been scaled up commensurately. The local subscriber lines for telephone and cable television are still using twisted pairs and coaxial cables. Most residential connections to the Internet are still through dial-up modems operating at a low speed on twisted pairs. As the demand for access bandwidth increases with emerging high-bandwidth applications, such as distance learning, high-definition television (HDTV), and video on demand (VoD), the last-mile access networks have become a bandwidth bottleneck in today's telecommunications infrastructure. To ease this bottleneck, it is imperative to provide sufficient bandwidth capacity in the access networks to open the bottleneck and thus present more opportunities for the provisioning of multiservices. Optical access solutions promise huge bandwidth to service providers and low-cost high-bandwidth services to end users and are therefore widely considered the technology of choice for next-generation access networks. To realize the vision of optical access networks, however, many key issues still need to be addressed, such as network architectures, signaling protocols, and implementation standards. The major challenges lie in the fact that an optical solution must be not only robust, scalable, and flexible, but also implemented at a low cost comparable to that of existing access solutions in order to increase the economic viability of many potential high-bandwidth applications. In recent years, optical access

Connections between locations are costly to build. The problem is to allocate costs of networks satisfying all connection...... demands. We use a few axioms to characterize allocation rules that truthfully implement cost minimizing networks satisfying all connection demands in a game where: (1) a central planner announces an allocation rule and a cost estimation rule; (2) every agent reports her own connection demand as well...... as all connection costs; (3) the central planner selects a cost minimizing network satisfying reported connection demands based on the estimated costs; and, (4) the planner allocates the true costs of the selected network.

    Networks of interconnected nodes have long played a key role in Cognitive Science, from artificial neural networks to spreading activation models of semantic memory. Recently, however, a new Network Science has been developed, providing insights into the emergence of global, system-scale properties in contexts as diverse as the Internet, metabolic reactions, and collaborations among scientists. Today, the inclusion of network theory into Cognitive Sciences, and the expansion of complex-systems science, promises to significantly change the way in which the organization and dynamics of cognitive and behavioral processes are understood.

    2016-01-01

    The development of new technologies for mapping structural and functional brain connectivity has led to the creation of comprehensive network maps of neuronal circuits and systems. The architecture of these brain networks can be examined and analyzed with a large variety of graph theory tools. Methods for detecting modules, or network communities, are of particular interest because they uncover major building blocks or subnetworks that are particularly densely connected, often corresponding to specialized functional components. A large number of methods for community detection have become available and are now widely applied in network neuroscience. This article first surveys a number of these methods, with an emphasis on their advantages and shortcomings; then it summarizes major findings on the existence of modules in both structural and functional brain networks and briefly considers their potential functional roles in brain evolution, wiring minimization, and the emergence of functional specialization and complex dynamics.

    2014-03-01

    Prior investigations of functional specialization have focused on the response profiles of particular brain regions. Given the growing emphasis on regional covariation, we propose to reframe these questions in terms of brain 'networks' (collections of regions jointly engaged by some mental process). Despite the challenges that investigations of the language network face, a network approach may prove useful in understanding the cognitive architecture of language. We propose that a language network plausibly includes a functionally specialized 'core' (brain regions that coactivate with each other during language processing) and a domain-general 'periphery' (a set of brain regions that may coactivate with the language core regions at some times but with other specialized systems at other times, depending on task demands). Framing the debate around network properties such as this may prove to be a more fruitful way to advance our understanding of the neurobiology of language. Copyright © 2013 Elsevier Ltd.

    Datta, Anwitaman; Buchegger, Sonja; Vu, Le-Hung; Strufe, Thorsten; Rzadca, Krzysztof

    Current Online social networks (OSN) are web services run on logically centralized infrastructure. Large OSN sites use content distribution networks and thus distribute some of the load by caching for performance reasons, nevertheless there is a central repository for user and application data. This centralized nature of OSNs has several drawbacks including scalability, privacy, dependence on a provider, need for being online for every transaction, and a lack of locality. There have thus been several efforts toward decentralizing OSNs while retaining the functionalities offered by centralized OSNs. A decentralized online social network (DOSN) is a distributed system for social networking with no or limited dependency on any dedicated central infrastructure. In this chapter we explore the various motivations of a decentralized approach to online social networking, discuss several concrete proposals and types of DOSN as well as challenges and opportunities associated with decentralization.

    Peer support groups have a long history and have been shown to improve health outcomes. With the increasing familiarity with online social networks like Facebook and ubiquitous access to the Internet, online social support networks are becoming popular. While studies have shown the benefit of these networks in providing emotional support or meeting informational needs, robust data on improving outcomes such as a decrease in health services utilization or reduction in adverse outcomes is lacking. These networks also pose unique challenges in the areas of patient privacy, funding models, quality of content, and research agendas. Addressing these concerns while creating patient-centred, patient-powered online support networks will help leverage these platforms to complement traditional healthcare delivery models in the current environment of value-based care.

  12. Visualization of Social Networks

    Chen, Ing-Xiang; Yang, Cheng-Zen

    With the ubiquitous characteristic of the Internet, today many online social environments are provided to connect people. Various social relationships are thus created, connected, and migrated from our real lives to the Internet environment from different social groups. Many social communities and relationships are also quickly constructed and connected via instant personal messengers, blogs, Twitter, Facebook, and a great variety of online social services. Since social network visualizations can structure the complex relationships between different groups of individuals or organizations, they are helpful to analyze the social activities and relationships of actors, particularly over a large number of nodes. Therefore, many studies and visualization tools have been investigated to present social networks with graph representations. In this chapter, we will first review the background of social network analysis and visualization methods, and then introduce various novel visualization applications for social networks. Finally, the challenges and the future development of visualizing online social networks are discussed.

    Poultry farming has been touted as one of the major ways by which poverty can be reduced in low-income economies like Ghana. Yet, anecdotally there is a high failure rate among these poultry farms. This current study seeks to understand the relationship between network ties and survival chances...... of small commercial poultry farms (SCPFs). We utilize data from a 2-year network survey of SCPFs in rural Ghana. The survival of these poultry farms are modelled using a lagged probit model of farms that persisted from 2014 into 2015. We find that network ties are important to the survival chances...... but this probability reduces as the number of industry ties increases but moderation with dynamic capability of the firm reverses this trend. Our findings show that not all network ties aid survival and therefore small commercial poultry farmers need to be circumspect in the network ties they cultivate and develop....

    Disclosed are a unified method and apparatus to classify, route, and process injected data packets into a network so as to belong to a plurality of logical networks, each implementing a specific flow of data on top of a common physical network. The method allows to locally identify collectives of packets for local processing, such as the computation of the sum, difference, maximum, minimum, or other logical operations among the identified packet collective. Packets are injected together with a class-attribute and an opcode attribute. Network routers, employing the described method, use the packet attributes to look-up the class-specific route information from a local route table, which contains the local incoming and outgoing directions as part of the specifically implemented global data flow of the particular virtual network.

    In the present paper we consider the allocation of cost in connection networks. Agents have connection demands in form of pairs of locations they want to be connected. Connections between locations are costly to build. The problem is to allocate costs of networks satisfying all connection demands....... We use three axioms to characterize allocation rules that truthfully implement cost minimizing networks satisfying all connection demands in a game where: (1) a central planner announces an allocation rule and a cost estimation rule; (2) every agent reports her own connection demand as well as all...... connection costs; and, (3) the central planner selects a cost minimizing network satisfying reported connection demands based on estimated connection costs and allocates true connection costs of the selected network....

  20. Tinnitus: Network pathophysiology-network pharmacology

    Directory of Open Access Journals (Sweden)

    Ana Belen eElgoyhen

    2012-01-01

    Full Text Available Tinnitus, the phantom perception of sound, is a prevalent disorder. One in 10 adults has clinically significant subjective tinnitus, and for 1 in 100, tinnitus severely affects their quality of life. Despite the significant unmet clinical need for a safe and effective drug targeting tinnitus relief, there is currently not a single FDA-approved drug on the market. The search for drugs that target tinnitus is hampered by the lack of a deep knowledge of the underlying neural substrates of this pathology. Recent studies are increasingly demonstrating that, as described for other central nervous system disorders, tinnitus is a pathology of brain networks. The application of graph theoretical analysis to brain networks has recently provided new information concerning their topology, their robustness and their vulnerability to attacks. Moreover, the philosophy behind drug design and pharmacotherapy in central nervous system pathologies is changing from that of magic bullets that target individual chemoreceptors or disease-causing genes into that of magic shotguns, promiscuous or dirty drugs that target disease-causing networks, also known as network pharmacology. In the present work we provide some insight into how this knowledge could be applied to tinnitus pathophysiology and pharmacotherapy.

  1. Network of networks in Linux operating system

    Wang, Haoqin; Chen, Zhen; Xiao, Guanping; Zheng, Zheng

    2016-04-01

    Operating system represents one of the most complex man-made systems. In this paper, we analyze Linux Operating System (LOS) as a complex network via modeling functions as nodes and function calls as edges. It is found that for the LOS network and modularized components within it, the out-degree follows an exponential distribution and the in-degree follows a power-law distribution. For better understanding the underlying design principles of LOS, we explore the coupling correlations of components in LOS from aspects of topology and function. The result shows that the component for device drivers has a strong manifestation in topology while a weak manifestation in function. However, the component for process management shows the contrary phenomenon. Moreover, in an effort to investigate the impact of system failures on networks, we make a comparison between the networks traced from normal and failure status of LOS. This leads to a conclusion that the failure will change function calls which should be executed in normal status and introduce new function calls in the meanwhile.

  2. Mobility Network and Safety

    Directory of Open Access Journals (Sweden)

    Adriana Galderisi

    2010-04-01

    Full Text Available Mobility network is crucial for ensuring territorial safety with respect to natural and technological hazards. They represent a basic support to community’s everyday life although being exposed elements often characterized by high vulnerability to different hazards and, in the meanwhile, strategic equipments for emergency management. Physical damages or the lack in functioning of those networks may greatly increase the loss of human lives caused by hazardous events as well as produce relevant economic damages at medium and long term. Although the relevance of the mobility networks in assuring territorial safety is at present largely recognized, risk analyses have been long focused on buildings’ vulnerability or, even where they have paid attention to mobility network, they have been mainly focused on the physical damages that a given hazard could may induce on individual elements of such network. It is recent the awareness that mobility network represents a system, characterized by relevant interdependences both among its elements and among network infrastructures and urban systems. Based on these assumptions, this paper points out the heterogeneous aspects of the mobility network vulnerability and their relevance in increasing the overall territorial or urban vulnerability to hazardous events. Therefore, an in-depth investigation of the concept of mobility network vulnerability is provided, in order to highlight the aspects mostly investigated and more recent research perspectives. Finally, a case study in the Campania Region is presented in order to point out how traditional risk analyses, generally referred to individual hazards, can sometimes led to invest in the mobility network improvement or development which, targeted to increase the security of a territory result, on the opposite, in an increase of the territorial vulnerability.

  4. Extracting information from multiplex networks.

    Iacovacci, Jacopo; Bianconi, Ginestra

    2016-06-01

    Multiplex networks are generalized network structures that are able to describe networks in which the same set of nodes are connected by links that have different connotations. Multiplex networks are ubiquitous since they describe social, financial, engineering, and biological networks as well. Extending our ability to analyze complex networks to multiplex network structures increases greatly the level of information that is possible to extract from big data. For these reasons, characterizing the centrality of nodes in multiplex networks and finding new ways to solve challenging inference problems defined on multiplex networks are fundamental questions of network science. In this paper, we discuss the relevance of the Multiplex PageRank algorithm for measuring the centrality of nodes in multilayer networks and we characterize the utility of the recently introduced indicator function Θ̃(S) for describing their mesoscale organization and community structure. As working examples for studying these measures, we consider three multiplex network datasets coming for social science.

  7. Articulation points in complex networks

    Science.gov (United States)

    Tian, Liang; Bashan, Amir; Shi, Da-Ning; Liu, Yang-Yu

    2017-01-01

    An articulation point in a network is a node whose removal disconnects the network. Those nodes play key roles in ensuring connectivity of many real-world networks, from infrastructure networks to protein interaction networks and terrorist communication networks. Despite their fundamental importance, a general framework of studying articulation points in complex networks is lacking. Here we develop analytical tools to study key issues pertinent to articulation points, such as the expected number of them and the network vulnerability against their removal, in an arbitrary complex network. We find that a greedy articulation point removal process provides us a different perspective on the organizational principles of complex networks. Moreover, this process results in a rich phase diagram with two fundamentally different types of percolation transitions. Our results shed light on the design of more resilient infrastructure networks and the effective destruction of terrorist communication networks.

  12. Network coding at different layers in wireless networks

    CERN Document Server

    2016-01-01

    This book focuses on how to apply network coding at different layers in wireless networks – including MAC, routing, and TCP – with special focus on cognitive radio networks. It discusses how to select parameters in network coding (e.g., coding field, number of packets involved, and redundant information ration) in order to be suitable for the varying wireless environments. The book explores how to deploy network coding in MAC to improve network performance and examines joint network coding with opportunistic routing to improve the successful rate of routing. In regards to TCP and network coding, the text considers transport layer protocol working with network coding to overcome the transmission error rate, particularly with how to use the ACK feedback of TCP to enhance the efficiency of network coding. The book pertains to researchers and postgraduate students, especially whose interests are in opportunistic routing and TCP in cognitive radio networks.

  13. Optical Network Testbeds Workshop

    2007-06-01

    This is the summary report of the third annual Optical Networking Testbed Workshop (ONT3), which brought together leading members of the international advanced research community to address major challenges in creating next generation communication services and technologies. Networking research and development (R&D) communities throughout the world continue to discover new methods and technologies that are enabling breakthroughs in advanced communications. These discoveries are keystones for building the foundation of the future economy, which requires the sophisticated management of extremely large qualities of digital information through high performance communications. This innovation is made possible by basic research and experiments within laboratories and on specialized testbeds. Initial network research and development initiatives are driven by diverse motives, including attempts to solve existing complex problems, the desire to create powerful new technologies that do not exist using traditional methods, and the need to create tools to address specific challenges, including those mandated by large scale science or government agency mission agendas. Many new discoveries related to communications technologies transition to wide-spread deployment through standards organizations and commercialization. These transition paths allow for new communications capabilities that drive many sectors of the digital economy. In the last few years, networking R&D has increasingly focused on advancing multiple new capabilities enabled by next generation optical networking. Both US Federal networking R&D and other national R&D initiatives, such as those organized by the National Institute of Information and Communications Technology (NICT) of Japan are creating optical networking technologies that allow for new, powerful communication services. Among the most promising services are those based on new types of multi-service or hybrid networks, which use new optical networking

    2016-03-01

    Airlines shape their route network by defining their routes through supply and demand considerations, paying little attention to network performance indicators, such as network robustness. However, the collapse of an airline network can produce high financial costs for the airline and all its geographical area of influence. The aim of this study is to analyze the topology and robustness of the network route of airlines following Low Cost Carriers (LCCs) and Full Service Carriers (FSCs) business models. Results show that FSC hubs are more central than LCC bases in their route network. As a result, LCC route networks are more robust than FSC networks.

    Much like individual microgrids, the range of opportunities and potential architectures of networked microgrids is very diverse. The goals of this scoping study are to provide an early assessment of research and development needs by examining the benefits of, risks created by, and risks to networked microgrids. At this time there are very few, if any, examples of deployed microgrid networks. In addition, there are very few tools to simulate or otherwise analyze the behavior of networked microgrids. In this setting, it is very difficult to evaluate networked microgrids systematically or quantitatively. At this early stage, this study is relying on inputs, estimations, and literature reviews by subject matter experts who are engaged in individual microgrid research and development projects, i.e., the authors of this study The initial step of the study gathered input about the potential opportunities provided by networked microgrids from these subject matter experts. These opportunities were divided between the subject matter experts for further review. Part 2 of this study is comprised of these reviews. Part 1 of this study is a summary of the benefits and risks identified in the reviews in Part 2 and synthesis of the research needs required to enable networked microgrids.

  1. Simulated Associating Polymer Networks

    Science.gov (United States)

    Billen, Joris

    Telechelic associating polymer networks consist of polymer chains terminated by endgroups that have a different chemical composition than the polymer backbone. When dissolved in a solution, the endgroups cluster together to form aggregates. At low temperature, a strongly connected reversible network is formed and the system behaves like a gel. Telechelic networks are of interest since they are representative for biopolymer networks (e.g. F-actin) and are widely used in medical applications (e.g. hydrogels for tissue engineering, wound dressings) and consumer products (e.g. contact lenses, paint thickeners). In this thesis such systems are studied by means of a molecular dynamics/Monte Carlo simulation. At first, the system in rest is studied by means of graph theory. The changes in network topology upon cooling to the gel state, are characterized. Hereto an extensive study of the eigenvalue spectrum of the gel network is performed. As a result, an in-depth investigation of the eigenvalue spectra for spatial ER, scale-free, and small-world networks is carried out. Next, the gel under the application of a constant shear is studied, with a focus on shear banding and the changes in topology under shear. Finally, the relation between the gel transition and percolation is discussed.

  2. Balanced Centrality of Networks

    Sciriha, Irene

    2014-01-01

    There is an age-old question in all branches of network analysis. What makes an actor in a network important, courted, or sought? Both Crossley and Bonacich contend that rather than its intrinsic wealth or value, an actor's status lies in the structures of its interactions with other actors. Since pairwise relation data in a network can be stored in a two-dimensional array or matrix, graph theory and linear algebra lend themselves as great tools to gauge the centrality (interpreted as importance, power, or popularity, depending on the purpose of the network) of each actor. We express known and new centralities in terms of only two matrices associated with the network. We show that derivations of these expressions can be handled exclusively through the main eigenvectors (not orthogonal to the all-one vector) associated with the adjacency matrix. We also propose a centrality vector (SWIPD) which is a linear combination of the square, walk, power, and degree centrality vectors with weightings of the various centralities depending on the purpose of the network. By comparing actors' scores for various weightings, a clear understanding of which actors are most central is obtained. Moreover, for threshold networks, the (SWIPD) measure turns out to be independent of the weightings. PMID:27437494

    The theoretically proven security of quantum key distribution (QKD) could revolutionize the way in which information exchange is protected in the future. Several field tests of QKD have proven it to be a reliable technology for cryptographic key exchange and have demonstrated nodal networks of point-to-point links. However, until now no convincing answer has been given to the question of how to extend the scope of QKD beyond niche applications in dedicated high security networks. Here we introduce and experimentally demonstrate the concept of a 'quantum access network': based on simple and cost-effective telecommunication technologies, the scheme can greatly expand the number of users in quantum networks and therefore vastly broaden their appeal. We show that a high-speed single-photon detector positioned at a network node can be shared between up to 64 users for exchanging secret keys with the node, thereby significantly reducing the hardware requirements for each user added to the network. This point-to-multipoint architecture removes one of the main obstacles restricting the widespread application of QKD. It presents a viable method for realizing multi-user QKD networks with efficient use of resources, and brings QKD closer to becoming a widespread technology.

    2010-08-01

    Full Text Available Our ultimate goal is to design transportation net- works whose dynamic performance metrics (e.g. pas- senger throughput, passenger delay, and insensitivity to weather disturbances are optimized. Here the fo- cus is on optimizing static features of the network that are known to directly affect the network dynamics. First, we present simulation results which support a connection between maximizing the first non-trivial eigenvalue of a network's Laplacian and superior air- port network performance. Then, we explore the ef- fectiveness of a tabu search heuristic for optimizing this metric by comparing experimental results to the- oretical upper bounds. We also consider generating upper bounds on a network's algebraic connectivity via the solution of semidefinite programming (SDP relaxations. A modification of an existing subgraph extraction algorithm is implemented to explore the underlying regional structures in the U.S. airport net- work, with the hope that the resulting localized struc- tures can be optimized independently and reconnected via a "backbone" network to achieve superior network performance.

  7. Scalable Virtual Network Mapping Algorithm for Internet-Scale Networks

    Science.gov (United States)

    Yang, Qiang; Wu, Chunming; Zhang, Min

    The proper allocation of network resources from a common physical substrate to a set of virtual networks (VNs) is one of the key technical challenges of network virtualization. While a variety of state-of-the-art algorithms have been proposed in an attempt to address this issue from different facets, the challenge still remains in the context of large-scale networks as the existing solutions mainly perform in a centralized manner which requires maintaining the overall and up-to-date information of the underlying substrate network. This implies the restricted scalability and computational efficiency when the network scale becomes large. This paper tackles the virtual network mapping problem and proposes a novel hierarchical algorithm in conjunction with a substrate network decomposition approach. By appropriately transforming the underlying substrate network into a collection of sub-networks, the hierarchical virtual network mapping algorithm can be carried out through a global virtual network mapping algorithm (GVNMA) and a local virtual network mapping algorithm (LVNMA) operated in the network central server and within individual sub-networks respectively with their cooperation and coordination as necessary. The proposed algorithm is assessed against the centralized approaches through a set of numerical simulation experiments for a range of network scenarios. The results show that the proposed hierarchical approach can be about 5-20 times faster for VN mapping tasks than conventional centralized approaches with acceptable communication overhead between GVNCA and LVNCA for all examined networks, whilst performs almost as well as the centralized solutions.

    The experimental observations and numerical studies with dissipative metabolic networks have shown that cellular enzymatic activity self-organizes spontaneously leading to the emergence of a Systemic Metabolic Structure in the cell, characterized by a set of different enzymatic reactions always locked into active states (metabolic core) while the rest of the catalytic processes are only intermittently active. This global metabolic structure was verified for Escherichia coli, Helicobacter pylori and Saccharomyces cerevisiae, and it seems to be a common key feature to all cellular organisms. In concordance with these observations, the cell can be considered a complex metabolic network which mainly integrates a large ensemble of self-organized multienzymatic complexes interconnected by substrate fluxes and regulatory signals, where multiple autonomous oscillatory and quasi-stationary catalytic patterns simultaneously emerge. The network adjusts the internal metabolic activities to the external change by means of flux plasticity and structural plasticity. In order to research the systemic mechanisms involved in the regulation of the cellular enzymatic activity we have studied different catalytic activities of a dissipative metabolic network under different external stimuli. The emergent biochemical data have been analysed using statistical mechanic tools, studying some macroscopic properties such as the global information and the energy of the system. We have also obtained an equivalent Hopfield network using a Boltzmann machine. Our main result shows that the dissipative metabolic network can behave as an attractor metabolic network. We have found that the systemic enzymatic activities are governed by attractors with capacity to store functional metabolic patterns which can be correctly recovered from specific input stimuli. The network attractors regulate the catalytic patterns, modify the efficiency in the connection between the multienzymatic complexes, and stably

    The problem of designing a cost-efficient network that survives the failure of one or more nodes or edges of the network is critical to modern telecommunications engineering. The method developed in this book is designed to solve such problems to optimality. In particular, a cutting plane approach is described, based on polyhedral combinatorics, that is ableto solve real-world problems of this type in short computation time. These results are of interest for practitioners in the area of communication network design. The book is addressed especially to the combinatorial optimization community, but also to those who want to learn polyhedral methods. In addition, interesting new research problemsare formulated.

    Today's wireless communications and networking practices are tightly coupled with economic considerations, to the extent that it is almost impossible to make a sound technology choice without understanding the corresponding economic implications. This book aims at providing a foundational introduction on how microeconomics, and pricing theory in particular, can help us to understand and build better wireless networks. The book can be used as lecture notes for a course in the field of network economics, or a reference book for wireless engineers and applied economists to understand how pricing

    Full Text Available Recent technological advances in integrated circuits, wireless networks, and physiological sensing have enabled miniature, lightweight, low power, intelligent monitoring devices to be integrated into a Body Area Network (BAN. This new type of technology hold much promise for future patient health monitoring. BANs promise inexpensive, unobtrusive, and unsupervised ambulatory monitoring during normal daily activities for long periods of time. However, in order for BANs to become ubiquitous and affordable, a number of challenging issues must be resolved, such as integration, standardisation, system design, customisation, security and privacy, and social issues. This paper presents an overview of many of these issues and indeed the background and rationale of body area networks.
