  1. AFRICAN-STYLE MEDIATION AND WESTERN-STYLE DIVORCE AND FAMILY MEDIATION: REFLECTIONS FOR THE SOUTH AFRICAN CONTEXT

    AE Boniface

    2012-12-01

    Full Text Available Both Western-styled mediation and African-styled mediation are practised in South Africa. Each of these models is applied in specific social contexts. In this article a brief explanation of what is meant by the term divorce and family mediation is provided. Thereafter the principles and processes of both Western-styled divorce and family mediation and African-styled group mediation are explored. Attention is given to the roles of mediators in both of these models as well as the ubuntu-styled values found in African group mediation. In Africa, there is a tradition of family neighbourhood negotiation facilitated by elders and an attitude of togetherness in the spirit of humanhood. Both of these show a commitment to the community concerned and a comprehensive view of life. In Africa conflicts are viewed as non-isolated events and are viewed in their social contexts. Not only are consequences for the disputing parties taken into account but also consequences for others in their families. These methods can be found in present-day methods, which are either used independently of imported Western structures or used alternatively to such structures. In this article the concept of mediation circles, as currently found in Western-styled mediation are also covered. Additionally, the provisions of the Children’s Act 38 of 2005 referring to mediation as well as the provisions of the Child Justice Act 75 of 2008 and family group conferencing in the realm of restorative justice in South Africa are critiqued. It is suggested that divorce and family mediation can learn from the principles of restorative justice applied during family group conferencing as well as from African-styled group mediation.

  2. From Conciliation to Mediation in Family Disputes-Harmonization of Croatian Family Legislation on Peaceful Resolution of Family Disputes with EU law

    Paula Poretti

    2015-01-01

    Full Text Available The reform process of family law was initiated with one aim to promote protection of family and children and harmonize Croatian law with European and international standards in this field. In this respect, the intervention institute governed by Croatian family law with the purpose to facilitate reconciliation or in cases where reconciliation between spouses is not achieved, to provide information regarding legal consequences of divorce and possibly to achieve agreement between spouses as for their relationship in future was deemed inadequate in regards to the approach provided by European documents on regulation of peaceful resolution of family disputes. Under the influence thereof, new family legislation redefines intervention and introduces mandatory counselling and family mediation as foundations of the system of alternative dispute resolution of all family disputes in Croatian law.

    2016-01-01

    Full Text Available Nowadays the understanding of the institute of marriage and its importance in the society has changed. Marriage is no longer assumed to be a commitment for a lifetime. As the principle of equality has replaced hierarchy as the guiding principle of family law it gave more grounds for family disputes and it became socially acceptable to leave marriages that are intolerable or merely unfulfilling. The aim of this article is to suggest an alternative dispute resolution method-mediation as a worthy option for resolving family conflicts.

  4. DISPUTE RESOLUTION AND MEDIATION ON CAPITAL MARKET

    CRISTIAN GHEORGHE

    2011-04-01

    Full Text Available Capital Market is usually depicted as a place for experts, for people with high trading skills. This is a half truth. There are entities established and functioning under strict scrutiny of Romanian National Securities Commission (RNSC, in compliance with Capital Market Law and regulations. There are also the investors, in many cases individuals involved in shares/financial instruments trade. In both cases disputes can rise. Disputes are inevitable a part of human interaction, hence the need for dispute resolution. First option is the judicial court system. Alternative dispute resolution comprises arbitration and mediation. Arbitration is an alternative choice to provide simpler, speedier and more accessible justice than ordinary courts as well as expertise in matters that are technical in nature and require special knowledge to adjudicate upon. Capital Market environment provides an institutional arbitration court for all participants, including investors. In many cases the agreement executed between participants under RNSC scrutiny The other option for settling disputes outside the court is mediation. Mediation can provide a much cheaper and quick extrajudicial resolution of disputes in commercial matters without time consuming procedures and rigid rules. Agreements resulting from mediation are more likely to be complied with voluntarily and are more likely to foster the commercial relationship between the parties. The interaction between investors and brokerage houses is based on investment services agreement concluded by parties. This is the usual framework for disputes between parties and the usual “landscape” for mediation on capital market.

  6. Mediating environmental disputes

    Lake, L.M.

    1977-09-01

    Environmental disputes and lawsuits are examined. Site-specific disputes focus on visible physical phenomena, such as a power plant or local river, and have an immediacy and intensity about them that make it politically hazardous for public officials to assume responsibility for resolving them. As new precedents in environmental case law become less frequent and the number of disputes increases, alternative processes for environmental conflict resolution, such as third-party intervention, become appropriate. Third-party intervention techniques of fact finding, conflict avoidance, conciliation and mediation have been applied to international, labor, prison, school, racial, and hospital disputes. Underlying concepts are described. Two case studies, the Snoqualmie Dam dispute in Washington and the West Side Highway dispute in New York City, illustrate the basic elements associated with third-party intervention. 1 map, 17 references.

  7. Mediatization

    Hjarvard, Stig

    2017-01-01

    Mediatization research shares media effects studies' ambition of answering the difficult questions with regard to whether and how media matter and influence contemporary culture and society. The two approaches nevertheless differ fundamentally in that mediatization research seeks answers...... to these general questions by distinguishing between two concepts: mediation and mediatization. The media effects tradition generally considers the effects of the media to be a result of individuals being exposed to media content, i.e. effects are seen as an outcome of mediated communication. Mediatization...... research is concerned with long-term structural changes involving media, culture, and society, i.e. the influences of the media are understood in relation to how media are implicated in social and cultural changes and how these processes come to create new conditions for human communication and interaction...

    Aleksandra Stoilkovska

    2015-06-01

    Full Text Available Disputes resolved with the use of mediation as a form of dispute resolution are rare (or at striking level in the practice in our country. In order to increase the number of disputes that were successfully completed based on mediation, it is necessary for the people to know about the alternative forms of resolving litigation. The lack of information contributes to the lack of trust in any resolution of the dispute except in the court. There is also the positive practice of resolving disputes through mediation macular placed in public. This Paper treats the action research which aims to connect the people awareness of mediation as a form of negotiation through which can quickly and easily, without major financial implications, to resolve any dispute. This paper is based on a survey with the members of Chamber of Mediators of the Republic of Macedonia.

  17. Childhood parental divorce and cortisol in young adulthood: evidence for mediation by family income.

    Kraft, Amy J; Luecken, Linda J

    2009-10-01

    Childhood parental divorce has been linked with negative physical and psychological health in adulthood, potentially due to alterations in adrenocortical activity resulting from chronic stress. The current study evaluated cortisol in 94 young adults (mean age 19.9) from families characterized by parental divorce (n=43) or intact parental marriages (n=51). Salivary cortisol was assessed prior to and at 3 time points after a challenging speech task. Participants from divorced families had significantly lower cortisol across the experimental period than those from intact families, even after controlling for family conflict and current depression and anxiety. Lower family income was also associated with lower cortisol, and partially mediated the relationship between parental divorce and cortisol. Findings suggest that childhood parental divorce is associated with attenuated cortisol in young adulthood, which may be explained by lower income in divorced families.

  18. Using therapeutic jurisprudence and preventive law to examine disputants' best interests in mediating cases about physicians' practices: a guide for medical regulators.

    Ferris, Lorraine E

    2004-01-01

    Therapeutic jurisprudence (TJ) and preventive law (PL) are used as two theoretical perspectives from which to examine the best interests of parties in mediation because of a dispute about a physician's practice. The focus is mediation provided by and/or for the medical regulator. The paper reviews the literature on TJ and PL, and their relationship to mediation, and demonstrates how medical regulators could benefit by working within a framework reflecting both these perspectives providing it does not involve an egregious matter. A TJ and PL framework would be of particular value in identifying cases for mediation and in evaluating resolutions to mediated disputes.

  8. LEGAL AND INSTITUTIONAL FRAMEWORK OF MEDIATION IN REPUBLIC OF MACEDONIA

    Andon Majhoshev

    2014-10-01

    Full Text Available Mediation as an alternative dispute resolution enables faster, more efficient and less costly resolution of disputes in relation to the proceedings. Its operation is based on the following principles: voluntary, equality of the parties, neutrality of the mediator, exclusion of the public, efficiency of the procedure, confidentiality of information, fairness. In Macedonia the mediation as an alternative dispute resolution was introduced by the Law on Mediation in 2006. However, besides this law, the resolution of disputes by mediation is regulated by other special laws such as the Family Law Act, Consumer Law, the Juvenile Justice, Law for the peaceful resolution of labor disputes, etc.. For effective functioning of the mediation, except legal regulation of mediation, and established appropriate institutional framework is an important link for a successful mediation. The institutional framework of mediation includes: Ministry of Justice - Sector for Mediation, Board for Mediation, the Mediators Chamber of Macedonia and mediator. All the above institutions have proper function in the system of mediation and their jurisdiction is governed normative-legal. The legal and institutional framework actually consists of mediation system in the country and represent a whole.

  11. Mediation and moderation of divorce effects on children's behavior problems.

    Weaver, Jennifer M; Schofield, Thomas J

    2015-02-01

    Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, we examined children's internalizing and externalizing behavior problems from age 5 to 15 years in relation to whether they had experienced a parental divorce. Children from divorced families had more behavior problems compared with a propensity-score-matched sample of children from intact families, according to both teachers and mothers. They exhibited more internalizing and externalizing problems at the first assessment after the parents' separation and at the last available assessment (age 11 years for teacher reports, or 15 years for mother reports). Divorce also predicted both short-term and long-term rank-order increases in behavior problems. Associations between divorce and child behavior problems were moderated by family income (assessed before the divorce) such that children from families with higher incomes prior to the separation had fewer internalizing problems than children from families with lower incomes prior to the separation. Higher levels of predivorce maternal sensitivity and child IQ also functioned as protective factors for children of divorce. Mediation analyses showed that children were more likely to exhibit behavior problems after the divorce if their postdivorce home environment was less supportive and stimulating, their mother was less sensitive and more depressed, and their household income was lower. We discuss avenues for intervention, particularly efforts to improve the quality of home environments in divorced families. PsycINFO Database Record (c) 2015 APA, all rights reserved.

  12. Mediation skills for conflict resolution in nursing education.

    Cheng, Fung Kei

    2015-07-01

    Encountering conflicts among family members in hospital produces burnout among nurses, implying a need for alternative dispute resolution training. However, current nursing education pays more attention to counselling skills training than to mediation. The present report examines the fundamental concepts of mediation, including its nature, basic assumptions and values, and compares those with counselling. Its implications may open a discussion on enhancing contemporary nursing education by providing mediation training in the workplace to nurses so that they can deal more effectively with disputes.

  13. Training parents to mediate sibling disputes affects children's negotiation and conflict understanding.

    Smith, Julie; Ross, Hildy

    2007-01-01

    The effects of training parents to use formal mediation procedures in sibling disputes were examined in 48 families with 5- to 10-years-old children, randomly assigned to mediation and control conditions. Children whose parents were trained in mediation were compared with those whose parents intervened normally. Parents reported that children used more constructive conflict resolution strategies, compromised more often, and controlled the outcomes of conflicts more often in mediation families than in control families. Observations indicated less negativity in children's independent negotiations of recurrent conflicts, better understanding of the role of interpretation in assessing blame, and better knowledge of their siblings' perspectives in the mediation group. Thus, both social and social-cognitive gains resulted from experience with constructive conflict resolution.

  15. The practice of mediation to resolve clinical, bioethical, and medical malpractice disputes.

    Lee, Danny W H; Lai, Paul B S

    2015-12-01

    Mediation is a voluntary process whereby a neutral and impartial third party-t-he mediator--is present to facilitate communication and negotiation between the disputing parties so that amicable settlements can be agreed. Being confidential and non-adversarial in nature, the mediation process and skills are particularly applicable in clinical practice to facilitate challenging communications following adverse events, to assist bioethical decision making and to resolve disputes. Mediation is also a more effective and efficient means of dispute resolution in medical malpractice claims when compared with civil litigation. Health care mediation teams should be set up at individual facilities to provide education and consultation services to frontline staff and patients. At a community level, the Government, the mediation community, and the health care professionals should join forces to promote mediation as a means to settle medical malpractice claims outside of the courtroom.

  16. Efficacy of family mediation and the role of family violence: study protocol.

    Cleak, Helen; Schofield, Margot; Bickerdike, Andrew

    2014-01-21

    Family law reforms in Australia require separated parents in dispute to attempt mandatory family dispute resolution (FDR) in community-based family services before court attendance. However, there are concerns about such services when clients present with a history of high conflict and family violence. This study protocol describes a longitudinal study of couples presenting for family mediation services. The study aims to describe the profile of family mediation clients, including type of family violence, and determine the impact of violence profiles on FDR processes and outcomes, such as the type and durability of shared parenting arrangements and clients' satisfaction with mediated agreements. A mixed method, naturalistic longitudinal design is used. The sampling frame is clients presenting at nine family mediation centres across metropolitan, outer suburban, and regional/rural sites in Victoria, Australia. Data are collected at pre-test, completion of mediation, and six months later. Self-administered surveys are administered at the three time points, and a telephone interview at the final post-test. The key study variable is family violence. Key outcome measures are changes in the type and level of acrimony and violent behaviours, the relationship between violence and mediated agreements, the durability of agreements over six months, and client satisfaction with mediation. Family violence is a major risk to the physical and mental health of women and children. This study will inform debates about the role of family violence and how to manage it in the family mediation context. It will also inform decision-making about mediation practices by better understanding how mediation impacts on parenting agreements, and the implications for children, especially in the context of family violence.

  18. Potential of mediation for resolving environmental disputes related to energy facilities

    None

    1979-12-01

    This study assesses the potential of mediation as a tool for resolving disputes related to the environmental regulation of new energy facilities and identifies possible roles the Federal government might play in promoting the use of mediation. These disputes result when parties challenge an energy project on the basis of its potential environmental impacts. The paper reviews the basic theory of mediation, evaluates specific applications of mediation to recent environmental disputes, discusses the views of environmental public-interest groups towards mediation, and identifies types of energy facility-related disputes where mediation could have a significant impact. Finally, potential avenues for the Federal government to encourage use of this tool are identified.

  19. Mediation Analysis with Multiple Mediators.

    VanderWeele, T J; Vansteelandt, S

    2014-01-01

    Recent advances in the causal inference literature on mediation have extended traditional approaches to direct and indirect effects to settings that allow for interactions and non-linearities. In this paper, these approaches from causal inference are further extended to settings in which multiple mediators may be of interest. Two analytic approaches, one based on regression and one based on weighting are proposed to estimate the effect mediated through multiple mediators and the effects through other pathways. The approaches proposed here accommodate exposure-mediator interactions and, to a certain extent, mediator-mediator interactions as well. The methods handle binary or continuous mediators and binary, continuous or count outcomes. When the mediators affect one another, the strategy of trying to assess direct and indirect effects one mediator at a time will in general fail; the approach given in this paper can still be used. A characterization is moreover given as to when the sum of the mediated effects for multiple mediators considered separately will be equal to the mediated effect of all of the mediators considered jointly. The approach proposed in this paper is robust to unmeasured common causes of two or more mediators.

    Full Text Available For over half a century now, section 2(a of the Arbitration Act 42 of 1965 has prohibited arbitration in respect of matrimonial and related matters. In this article it will be illustrated that this prohibition is clearly incompatible with present-day demands. Today there is a strong tendency in public policy towards alternative dispute resolution processes such as arbitration. As any recommendations that arbitration should be applied to family law disputes must be anchored in an analysis of the specific character of the arbitral remedy, the article begins by giving a broad overview of the nature of arbitration. This is followed by a discussion of the present-day demand for family arbitration, which examines the problems experienced with the adversarial system of litigation in resolving family law disputes, party autonomy, the development of alternative dispute resolution processes such as mediation and arbitration, the special synergy between mediation and arbitration, the success of arbitration in other fields of law and possible forerunners for family arbitration in South Africa. Inherent in the demand for family law arbitration are the many advantages of arbitration, which are also touched upon. Thirdly, current trends in England, Australia, the United States of America, Canada and India are analysed so as to identify a suitable family law arbitration model for South Africa. Special attention is paid to the matters that should be referred to arbitration – for example, should it be confined to matrimonial property and financial disputes or extended to all matters incidental to divorce or family breakdown, including children's issues? Other questions examined include whether family arbitration should comply with substantive law only, who should act as arbitrators, whether family arbitration should be voluntary or compulsory, what the court's role in the family arbitration process should be, and whether family law arbitration should be

  2. Mediation Analysis with Multiple Mediators

    VanderWeele, T.J.; Vansteelandt, S.

    2014-01-01

    Recent advances in the causal inference literature on mediation have extended traditional approaches to direct and indirect effects to settings that allow for interactions and non-linearities. In this paper, these approaches from causal inference are further extended to settings in which multiple mediators may be of interest. Two analytic approaches, one based on regression and one based on weighting are proposed to estimate the effect mediated through multiple mediators and the effects throu...

  4. Evaluation of the third-party mediation mechanism for medical disputes in China.

    Zhao, Min

    2011-09-01

    Medical disputes have been increasing in recent years in China, which cause growing tension between doctors and patients. In many locations, it has started as a practice of exploring diversified dispute settlement methods. Great importance has been attached to the non-lawsuit model through third-party mediation, which might have been led by professional organizations, insurance companies, People's Mediation Committees, or three-level governmental authorities. Those have contributed to a rapid effective resolution of medical disputes. However, there are some deficiencies that need to be addressed and fixed up, thus calling for improvement, such as the lack of a sustainable supporting mechanism, unclear legal status of the mediation institutions and mediation agreements, patching up a quarrel by only compensation.

  5. Complex Mediation

    Bødker, Susanne; Andersen, Peter Bøgh

    2005-01-01

    This article has its starting point in a large number of empirical findings regarding computer-mediated work. These empirical findings have challenged our understanding of the role of mediation in such work; on the one hand as an aspect of communication and cooperation at work and on the other hand...... as an aspect of human engagement with instruments of work. On the basis of previous work in activity-theoretical and semiotic human—computer interaction, we propose a model to encompass both of these aspects. In a dialogue with our empirical findings we move on to propose a number of types of mediation...... that have helped to enrich our understanding of mediated work and the design of computer mediation for such work....

  13. The cerebellum mediates conflict resolution.

    Schweizer, Tom A; Oriet, Chris; Meiran, Nachshon; Alexander, Michael P; Cusimano, Michael; Stuss, Donald T

    2007-12-01

    Regions within the frontal and parietal cortex have been implicated as important neural correlates for cognitive control during conflict resolution. Despite the extensive reciprocal connectivity between the cerebellum and these putatively critical cortical areas, a role for the cerebellum in conflict resolution has never been identified. We used a task-switching paradigm that separates processes related to task-set switching and the management of response conflict independent of motor processing. Eleven patients with chronic, focal lesions to the cerebellum and 11 healthy controls were compared. Patients were slower and less accurate in conditions involving conflict resolution. In the absence of response conflict, however, tasks-witching abilities were not impaired in our patients. The cerebellum may play an important role in coordinating with other areas of cortex to modulate active response states. These results are the first demonstration of impaired conflict resolution following cerebellar lesions in the presence of an intact prefrontal cortex.

  14. Mediation and Moderation of Divorce Effects on Children’s Behavior Problems

    Weaver, Jennifer; Schofield, Thomas

    2016-01-01

    Using data from the NICHD Study of Early Child Care and Youth Development, we examined children’s internalizing and externalizing behavior problems from age 5 to age 15 in relation to whether they had experienced a parental divorce. Children from divorced families had more behavior problems compared with a propensity score-matched sample of children from intact families according to both teachers and mothers. They exhibited more internalizing and externalizing problems at the first assessment after the parents’ separation and at the last available assessment (age 11 for teacher reports, or age 15 for mother reports). Divorce also predicted both short-term and long-term rank-order increases in behavior problems. Associations between divorce and child behavior problems were moderated by family income (assessed before the divorce) such that children from families with higher incomes prior to the separation had fewer internalizing problems than children from families with lower incomes prior to the separation. Higher levels of pre-divorce maternal sensitivity and child IQ also functioned as protective factors for children of divorce. Mediation analyses showed that children were more likely to exhibit behavior problems after the divorce if their post-divorce home environment was less supportive and stimulating, their mother was less sensitive and more depressed, and their household income was lower. We discuss avenues for intervention, particularly efforts to improve the quality of home environments in divorced families. PMID:25419913

  17. Divorce, approaches to learning, and children's academic achievement: a longitudinal analysis of mediated and moderated effects.

    Anthony, Christopher J; DiPerna, James Clyde; Amato, Paul R

    2014-06-01

    Data from the Early Childhood Longitudinal Study--Kindergarten Cohort (ECLS-K) were used to test the hypothesis that approaches to learning (ATL) mediates the link between parental divorce and academic achievement. Fixed effects regression was utilized to test for mediation, and subsequent moderation analyses examining gender and age at time of divorce also were conducted. Results indicated that divorce was associated with less growth in test scores and that ATL mediated 18% and 12% of this association in reading and mathematics respectively. Parental divorce also was associated with larger negative effects for children who experienced divorce at an older age as well as for girls' mathematics test scores. These findings contribute to the understanding of the impact of parental divorce on children's academic achievement and underscore the importance of focusing on the variability of child outcomes following parental divorce.

  18. Predicting the decision to pursue mediation in civil disputes: a hierarchical classes analysis.

    Reich, Warren A; Kressel, Kenneth; Scanlon, Kathleen M; Weiner, Gary A

    2007-11-01

    Clients (N = 185) involved in civil court cases completed the CPR Institute's Mediation Screen, which is designed to assist in making a decision about pursuing mediation. The authors modeled data using hierarchical classes analysis (HICLAS), a clustering algorithm that places clients into 1 set of classes and CPRMS items into another set of classes. HICLAS then links the sets of classes so that any class of clients can be identified in terms of the classes of items they endorsed. HICLAS-derived item classes reflected 2 underlying themes: (a) suitability of the dispute for a problem-solving process and (b) potential benefits of mediation. All clients who perceived that mediation would be beneficial also believed that the context of their conflict was favorable to mediation; however, not all clients who saw a favorable context believed they would benefit from mediation. The majority of clients who agreed to pursue mediation endorsed items reflecting both contextual suitability and perceived benefits of mediation.

  20. [Children in family mediation: A practice model].

    Mayer, Stefan; Normann, Katrin

    2006-01-01

    The authors briefly describe the history of family mediation under the perspective of the role of the children in the process of mediation. They state that originally children were not directly included. But through empirical studies and different higher escalated families asking for help by mediation, the inclusion of children got an important issue in theory and practice. The discussion began with the question in which phases of the mediation process the children should be included - it went to the issue of the age of the children - and the authors propose to take the amount of escalation in the family as the most important point of reference to decide if and how the children should be included. They suggest to diagnose the loss of responsibility and autonomy of the parents on a nine level scale (from F. Glasl) with the parents and to decide and negotiate with them how the children will be included. They describe five different settings of inclusion of the children.

  2. Long-term impact of parental divorce on intimate relationship quality in adulthood and the mediating role of psychosocial resources.

    Mustonen, Ulla; Huurre, Taina; Kiviruusu, Olli; Haukkala, Ari; Aro, Hillevi

    2011-08-01

    The purpose of this 16-year prospective follow-up study was to investigate the association between parental divorce in childhood and intimate relationship quality in adulthood. The mediating role of psychosocial resources (parent-child relationships at 16 years, self-esteem and social support at 32 years) in this association was also studied. All 16 year olds of one Finnish city completed questionnaires at school and were followed up by postal questionnaires at 32 years of age (n = 1,471). Results showed that women and men from divorced families were more often divorced or separated at the age of 32 years than those from nondivorced families. However, parental divorce was associated with poorer intimate relationship quality only among women. Women from divorced families also had poorer relationships with their father and mother in adolescence, and they had lower self-esteem and satisfaction with social support in adulthood than women from intact families. No such associations were found among men. The impact of parental divorce on intimate relationship quality among women was partially mediated by mother-daughter relationship, self-esteem, and satisfaction with social support. The mediating role of mother-daughter relationship was not direct, however, but was mediated via self-esteem and satisfaction with social support. Our findings indicate that parental divorce affects daughters more than sons. In the context of parental divorce, the mother-daughter relationship in adolescence is important for the development of later psychosocial resources and, via them, for intimate relationship quality.

  3. Resilience and rejection sensitivity mediate long-term outcomes of parental divorce.

    Schaan, Violetta K; Vögele, Claus

    2016-11-01

    Increasing divorce rates leave more and more children to deal with the separation of their parents. Recent research suggests that children of divorced parents more often experience psychological and physical symptoms than children of non-divorced parents. The processes that mediate the relationship between parental divorce and ill-health, however, are still elusive. This study investigated the mediating role of psychological factors such as resilience and rejection sensitivity on the long-term consequences of parental divorce in young adults. One hundred and ninety-nine participants (mean age 22.3 years) completed an online survey, including measures of mental health, childhood trauma, resilience, and rejection sensitivity. Participants with divorced parents (33 %) reported increased levels of psychological symptoms, childhood trauma, rejection sensitivity, and lower levels of resilience. The association between parental divorce and mental health was fully mediated by resilience, rejection sensitivity, and childhood trauma. The mediation model explained up to 44 % of the total variance in mental health symptoms. Resilience and rejection sensitivity are crucial factors for successful coping with the experience of parental separation. Prevention programs that help to boost children's resilience might help to reduce the long-term effects of parental divorce on their attachment style (e.g., rejection sensitivity), thereby improving their mental health on the long run. Furthermore, the results call for parental awareness and counseling to target and reduce the observed increased level of childhood trauma. Limitations concern the cross-sectional and retrospective design of the study.

  11. Causal mediation analysis with multiple mediators.

    Daniel, R M; De Stavola, B L; Cousens, S N; Vansteelandt, S

    2015-03-01

    In diverse fields of empirical research-including many in the biological sciences-attempts are made to decompose the effect of an exposure on an outcome into its effects via a number of different pathways. For example, we may wish to separate the effect of heavy alcohol consumption on systolic blood pressure (SBP) into effects via body mass index (BMI), via gamma-glutamyl transpeptidase (GGT), and via other pathways. Much progress has been made, mainly due to contributions from the field of causal inference, in understanding the precise nature of statistical estimands that capture such intuitive effects, the assumptions under which they can be identified, and statistical methods for doing so. These contributions have focused almost entirely on settings with a single mediator, or a set of mediators considered en bloc; in many applications, however, researchers attempt a much more ambitious decomposition into numerous path-specific effects through many mediators. In this article, we give counterfactual definitions of such path-specific estimands in settings with multiple mediators, when earlier mediators may affect later ones, showing that there are many ways in which decomposition can be done. We discuss the strong assumptions under which the effects are identified, suggesting a sensitivity analysis approach when a particular subset of the assumptions cannot be justified. These ideas are illustrated using data on alcohol consumption, SBP, BMI, and GGT from the Izhevsk Family Study. We aim to bridge the gap from "single mediator theory" to "multiple mediator practice," highlighting the ambitious nature of this endeavor and giving practical suggestions on how to proceed. © 2014 The Authors Biometrics published by Wiley Periodicals, Inc. on behalf of International Biometric Society.

  14. Profession of mediator as the professional provider of the mediation process

    Jernej Šoštar

    2017-03-01

    Full Text Available The civil mediation programme, which is a court-connected programme, established as a form of alternative dispute resolution, is increasingly gaining ground as a field with its own theoretical and practical knowledge, principles and basic rules. Mediation has already set up its own body of knowledge, based on studies, classification of cases and the analyses of the results. In this article, we examine whether in the context of the development of mediation in Slovenia we might already talk about the profession of the mediator, defined as a provider of the mediation process. We examine the court-connected civil mediation and mediators who mediate at the court-connected civil mediation, and define them theoretically. By interviewing the mediation experts and mediators we examine their opinions about mediators and the court mediation. We examine the legal basis for the court-connected mediation programmes in Slovenia as well as in the European Union. Proceeding from our findings we conclude that the legal regulation of the court mediation in Slovenia is well established, and that the mediators of the court-connected civil mediation programmes can be accepted as the professional providers of the mediation process.

  17. mediation: R Package for Causal Mediation Analysis

    Dustin Tingley

    2014-09-01

    Full Text Available In this paper, we describe the R package mediation for conducting causal mediation analysis in applied empirical research. In many scientific disciplines, the goal of researchers is not only estimating causal effects of a treatment but also understanding the process in which the treatment causally affects the outcome. Causal mediation analysis is frequently used to assess potential causal mechanisms. The mediation package implements a comprehensive suite of statistical tools for conducting such an analysis. The package is organized into two distinct approaches. Using the model-based approach, researchers can estimate causal mediation effects and conduct sensitivity analysis under the standard research design. Furthermore, the design-based approach provides several analysis tools that are applicable under different experimental designs. This approach requires weaker assumptions than the model-based approach. We also implement a statistical method for dealing with multiple (causally dependent mediators, which are often encountered in practice. Finally, the package also offers a methodology for assessing causal mediation in the presence of treatment noncompliance, a common problem in randomized trials.

    Meade, Patrick; Seiberg, Nathan; Shih, David

    2009-01-01

    We give a general definition of gauge mediated supersymmetry breaking which encompasses all the known gauge mediation models. In particular, it includes both models with messengers as well as direct mediation models. A formalism for computing the soft terms in the generic model is presented. Such a formalism is necessary in strongly-coupled direct mediation models where perturbation theory cannot be used. It allows us to identify features of the entire class of gauge mediation models and to distinguish them from specific signatures of various subclasses. (author)

  1. Ghosts of inventions: Patent law's digital mediations.

    Kang, Hyo Yoon

    2018-04-01

    This article examines the shifts in the material ordering of inventions in patent law organization and their effects on the meaning and scope of inventions as intellectual property. Formats and media are constitutive of the establishment and stabilization of inventions as objects of intellectual property. Modern patent law's materiality had been dominated by paper documents but ever more consists of digital images, files, and networked data. The article traces and analyzes such effects of digital media on the meaning of intellectual/intangible property and argues that inventions increasingly matter as digital data in the legal realm.

  3. Bayesian dynamic mediation analysis.

    Huang, Jing; Yuan, Ying

    2017-12-01

    Most existing methods for mediation analysis assume that mediation is a stationary, time-invariant process, which overlooks the inherently dynamic nature of many human psychological processes and behavioral activities. In this article, we consider mediation as a dynamic process that continuously changes over time. We propose Bayesian multilevel time-varying coefficient models to describe and estimate such dynamic mediation effects. By taking the nonparametric penalized spline approach, the proposed method is flexible and able to accommodate any shape of the relationship between time and mediation effects. Simulation studies show that the proposed method works well and faithfully reflects the true nature of the mediation process. By modeling mediation effect nonparametrically as a continuous function of time, our method provides a valuable tool to help researchers obtain a more complete understanding of the dynamic nature of the mediation process underlying psychological and behavioral phenomena. We also briefly discuss an alternative approach of using dynamic autoregressive mediation model to estimate the dynamic mediation effect. The computer code is provided to implement the proposed Bayesian dynamic mediation analysis. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Just as the types and natures of disputes increase with the economic and cultural development of any society, the mechanisms of dealing with them take a special importance as well. Besides dispute resolution by state bodies that are established by law, alternative ways for resolving disputes are developing increasingly and are receiving a special importance as well. The alternative solution of a dispute is nothing more than an alternative for resolving the dispute outside the judicial system, where the main ways are mediation and arbitration. Alternative solutions to disputes are widespread in countries of common law systems, considering that most disputes are solved in this way. In this article we will examine mediation and its development especially in Albania. Mediation is a way to resolve disputes between two or more parties, where a third person, the mediator, negotiates with the parties so that they arrive at a solution acceptable to all.

  5. THE INCLUSION OF / FOCUS ON CHILDREN IN FAMILY MEDIATION: A REVIEW OF STUDIES AND FUTURE PROPOSALS

    Carles Rodríguez-Domínguez

    2015-09-01

    Full Text Available Mediation is an established model for conflict resolution, backed by the international community in relation to family law, to help parents seeking solutions to family problems in child custody cases. The aim of this article is to review the advantages and/or disadvantages presented in the studies with child-inclusive or child-focused interventions in family mediation processes. In the present research, we carry out a review of studies realised in Australia, New Zealand, some counties in the US and in Europe; meta-analysis and review studies of 'child inclusive' investigations, international guidelines that support listening to children and also studies that criticise it. While mediation has existed for four decades in other countries, in Spain it has only arisen since the enactment of Law (1/2001 of Family Mediation in Catalonia, followed by other local regulations, which explains why sufficient studies might not yet exist. In some countries a new paradigm is emerging, aimed at the inclusion of children due to the favourable findings in family mediation processes, although a multiple and flexible approach in the field of family mediation intervention is necessary.

  6. Legal and Psychological Aspects of Mediation

    Dobrokhotova E. N.

    2016-01-01

    Full Text Available The article focuses on gradual innovation of mediation into the practice of social conflict resolution in the light of legal and psychological means of mediation. While mediation is perceived as a conflictological concept and is more widely used in dispute settlement and resolution, a new interdisciplinary field of theoretical knowledge with its own conceptual framework as well as a new professional and practical field are beginning to form both in Russia and in other countries. As theoretical and practical aspects of innovation in mediation require consolidation not only for its national development but also for the guaranteed international cooperation, the article touches upon some of the particular theoretical issues of the topic in question: terminological consistency, consolidation of the system of mediation principles, the phenomenon of juridisation of mediation and its limits.

  7. Flexible Mediation Analysis With Multiple Mediators.

    Steen, Johan; Loeys, Tom; Moerkerke, Beatrijs; Vansteelandt, Stijn

    2017-07-15

    The advent of counterfactual-based mediation analysis has triggered enormous progress on how, and under what assumptions, one may disentangle path-specific effects upon combining arbitrary (possibly nonlinear) models for mediator and outcome. However, current developments have largely focused on single mediators because required identification assumptions prohibit simple extensions to settings with multiple mediators that may depend on one another. In this article, we propose a procedure for obtaining fine-grained decompositions that may still be recovered from observed data in such complex settings. We first show that existing analytical approaches target specific instances of a more general set of decompositions and may therefore fail to provide a comprehensive assessment of the processes that underpin cause-effect relationships between exposure and outcome. We then outline conditions for obtaining the remaining set of decompositions. Because the number of targeted decompositions increases rapidly with the number of mediators, we introduce natural effects models along with estimation methods that allow for flexible and parsimonious modeling. Our procedure can easily be implemented using off-the-shelf software and is illustrated using a reanalysis of the World Health Organization's Large Analysis and Review of European Housing and Health Status (WHO-LARES) study on the effect of mold exposure on mental health (2002-2003). © The Author(s) 2017.

    This study analyzes how a group of ‘mediators’ in a large, multinational company adapted a computer-mediated communication technology (a ‘virtual workspace’) to the organizational context (and vice versa) by modifying features of the technology, providing ongoing support for users, and promoting...... appropriate conventions of use. Our findings corroborate earlier research on technology-use mediation, which suggests that such mediators can exert considerable influence on how a particular technology will be established and used in an organization. However, this study also indicates that the process...... of technology-use mediation is more complex and indeterminate than earlier literature suggests. In particular, we want to draw attention to the fact that advanced computer-mediated communication technologies are equivocal and that technology-use mediation consequently requires ongoing sensemaking (Weick 1995)....

  12. Mediator assessment, documentation, and disposition of child custody cases involving intimate partner abuse: a naturalistic evaluation of one county's practices.

    Beck, Connie J A; Walsh, Michele E; Mechanic, Mindy B; Taylor, Caitilin S

    2010-06-01

    The contentious and costly nature of the adversarial process for resolving child custody disputes has prompted scholars, practitioners, and policy makers to advocate for the development and implementation of less divisive forms of dispute resolution, notably, mediation. Mediation has been championed for its potential to resolve disputes with less acrimony among disputants, reduced economic costs, increased satisfaction with outcomes, and fewer adverse consequences for family members. Despite the increasing popularity, arguments have cautioned against the use of mandated mediation when intimate partner abuse (IPA) is alleged. This research documents a mediation screening process and models mediators' decision-making process as instantiated, naturally, in one jurisdiction.

  13. Implementing general gauge mediation

    Carpenter, Linda M.; Dine, Michael; Festuccia, Guido; Mason, John D.

    2009-01-01

    Recently there has been much progress in building models of gauge mediation, often with predictions different than those of minimal gauge mediation. Meade, Seiberg, and Shih have characterized the most general spectrum which can arise in gauge-mediated models. We discuss some of the challenges of building models of general gauge mediation, especially the problem of messenger parity and issues connected with R symmetry breaking and CP violation. We build a variety of viable, weakly coupled models which exhibit some or all of the possible low energy parameters.

  14. Use of mediation to resolve the dispute over low-head hydroelectric development at Swan Lake

    O' Connor, D.

    1980-08-01

    In 1978, the Maine Hydroelectric Development Corporation announced that the company planned to renovate five dams on the Goose River near Belfast, Maine to generate electricity. The most important part of the plan involved the use of the first of the dams, at the lower end of Swan Lake, to regulate the flow of water to the downstream dams. For Maine Hydro, management of the Swan Lake dam could make an otherwise marginal proposal lucrative. However, Swan Lake is vitally important to the residents of Swanville. The town was so concerned about the impact of this proposed hydroelectric project that it petitioned the Federal Energy Regulatory Commission (FERC) to deny Maine Hydro's application on the grounds that it would damage the environment, reduce property values and eliminate recreational opportunities for its citizens. This report was written by the mediator of the dispute and represents the views and behavior of the parties as the mediator understood them. It is intended to present the mediator's observations in a way which will inform and assist others who may someday face a difficult situation like the one the Town of Swanville and Maine Hydroelectric Development Corporation faced, and successfully resolved, in the spring and summer of 1979.

  20. The multitalented Mediator complex.

    Carlsten, Jonas O P; Zhu, Xuefeng; Gustafsson, Claes M

    2013-11-01

    The Mediator complex is needed for regulated transcription of RNA polymerase II (Pol II)-dependent genes. Initially, Mediator was only seen as a protein bridge that conveyed regulatory information from enhancers to the promoter. Later studies have added many other functions to the Mediator repertoire. Indeed, recent findings show that Mediator influences nearly all stages of transcription and coordinates these events with concomitant changes in chromatin organization. We review the multitude of activities associated with Mediator and discuss how this complex coordinates transcription with other cellular events. We also discuss the inherent difficulties associated with in vivo characterization of a coactivator complex that can indirectly affect diverse cellular processes via changes in gene transcription.

  2. Screening for Partner Violence Among Family Mediation Clients: Differentiating Types of Abuse.

    Cleak, Helen; Schofield, Margot J; Axelsen, Lauren; Bickerdike, Andrew

    2018-04-01

    Family mediation is mandated in Australia for couples in dispute over separation and parenting as a first step in dispute resolution, except where there is a history of intimate partner violence. However, validation of effective well-differentiated partner violence screening instruments suitable for mediation settings is at an early phase of development. This study contributes to calls for better violence screening instruments in the mediation context to detect a differentiated range of abusive behaviors by examining the reliability and validity of both established scales, and newly developed scales that measured intimate partner violence by partner and by self. The study also aimed to examine relationships between types of abuse, and between gender and types of abuse. A third aim was to examine associations between types of abuse and other relationship indicators such as acrimony and parenting alliance. The data reported here are part of a larger mixed method, naturalistic longitudinal study of clients attending nine family mediation centers in Victoria, Australia. The current analyses on baseline cross-sectional screening data confirmed the reliability of three subscales of the Conflict Tactics Scale (CTS2), and the reliability and validity of three new scales measuring intimidation, controlling and jealous behavior, and financial control. Most clients disclosed a history of at least one type of violence by partner: 95% reported psychological aggression, 72% controlling and jealous behavior, 50% financial control, and 35% physical assault. Higher rates of abuse perpetration were reported by partner versus by self, and gender differences were identified. There were strong associations between certain patterns of psychologically abusive behavior and both acrimony and parenting alliance. The implications for family mediation services and future research are discussed.

  3. [Mediation in schools].

    Mickley, Angela

    2006-01-01

    In this article the guiding questions concern the objectives and effectiveness of introducing mediation into an existing school culture of dominance, competition and selection. In addition the necessity will be shown of combining conflict resolution with organisational development and the introduction of a consensual ethics and behaviour code to attain sustainable results in creating a constructive and healthy school environment. Given scarce resources and little time the decisive role of artistic methods will be looked at in providing young people with flexible methods of expressing and negotiating their interests in a changing environment of values and power structures. Some aspects of the development of nonviolent communication, conflict resolution and mediation methods in schools in Germany will be focused on with special emphasis on the type of intervention used and its long term sustainable effects.

    2012-07-01

    We extend the framework of general gauge mediation to cases where the mediating fields have a nontrivial spectral function, as might arise from strong dynamics. We demonstrate through examples that this setup describes a broad class of possible models of gauge mediated supersymmetry breaking. A main emphasis is to give general formulas for cross sections for σ(visible → hidden) in these resonance models. We will also give formulas for soft masses, A-terms and demonstrate the framework with a holographic setup.

    We generalize the so-called 'deflected anomaly mediation' scenario to the case where threshold corrections of heavy messengers to the sparticle squared masses are positive. A concrete model realizing this scenario is also presented. The tachyonic slepton problem can be fixed with only a pair of messengers. The resultant sparticle mass spectrum is quite different from that in the conventional deflected anomaly mediation scenario, but is similar to the one in the gauge mediation scenario. The lightest sparticle is mostly B-ino

  8. Polyarene mediators for mediated redox flow battery

    Delnick, Frank M.; Ingersoll, David; Liang, Chengdu

    2018-01-02

    The fundamental charge storage mechanisms in a number of currently studied high energy redox couples are based on intercalation, conversion, or displacement reactions. With exception to certain metal-air chemistries, most often the active redox materials are stored physically in the electrochemical cell stack thereby lowering the practical gravimetric and volumetric energy density as a tradeoff to achieve reasonable power density. In a general embodiment, a mediated redox flow battery includes a series of secondary organic molecules that form highly reduced anionic radicals as reaction mediator pairs for the reduction and oxidation of primary high capacity redox species ex situ from the electrochemical cell stack. Arenes are reduced to stable anionic radicals that in turn reduce a primary anode to the charged state. The primary anode is then discharged using a second lower potential (more positive) arene. Compatible separators and solvents are also disclosed herein.

  9. Dissociation in mediation

    Daniela Muraru

    2008-01-01

    Full Text Available This paper approaches several texts that are part of the so-called discourse of mediation, adopting a pragma-dialectical perspective of the theory of dissociation. It is an attempt to identify the uses of dissociative patterns, with special emphasis on the indicators of dissociation. The paper investigates the various uses of the concept of dissociation as a discursive technique in the argumentation on the different aspects that are involved in international conflict, such as the discussion of the notion of peace. The purpose is to identify the role of dissociation, as a device strategically used by the mediator to help the parties minimize the disagreement space, and come to a conflict resolution.

  15. Childhood family disruption and adult height: is there a mediating role of puberty?

    Sheppard, Paula; Garcia, Justin R; Sear, Rebecca

    2015-11-24

    Childhood family background is known to be associated with child growth and development, including the onset of puberty, but less is known about the influence of childhood family disruption on outcomes in later life. Given the associations between early family disruption and childhood development, we predicted that there may be long-term health-relevant consequences of childhood disruption. Using data from a large US interview sample (n = 16 207), we test if death or divorce of parents, at different childhood periods, was associated with adult stature, and whether age at puberty mediated this relationship, for men and women. RESULTS MEN: : parental death and divorce during early childhood was associated with shorter adult height, and later puberty. Later puberty was associated with shorter adult height. Path analyses demonstrated that the relationship between parental divorce and height was completely mediated by age at puberty; although parental death was only partially mediated by age at puberty. WOMEN: the father's death during early childhood was associated with earlier puberty, which was in turn associated with shorter adult stature. The relationship between paternal death and height is entirely mediated by age at puberty; no evidence of a direct relationship between childhood family disruption and adult height. Early childhood familial disruption is associated with shorter height for men, and is partially mediated by later puberty. For women, the relationship between father's death, and height was completely mediated by earlier puberty. These findings indicate that disruption during childhood can have long-reaching health repercussions, particularly for boys. © The Author(s) 2015.

  16. How did it work? Who did it work for? Mediation in the context of a moderated prevention effect for children of divorce.

    Tein, Jenn-Yun; Sandler, Irwin N; MacKinnon, David P; Wolchik, Sharlene A

    2004-08-01

    This study presents a reanalysis of data from an effective preventive intervention for children from divorced families to test mediation of program effects. The study involved 157 children, age 9-12 years, who were randomly assigned to a parenting program or a literature control condition. Program effects to reduce posttest internalizing problems were mediated through improvement in mother-child relationship quality. Program effects to reduce externalizing problems at posttest and 6 months were mediated through improvement in posttest parental methods of discipline and mother-child relationship quality. The study also describes a new methodology to test mediation of Program x Baseline Status interactions. Analyses demonstrate mediation effects primarily for children who began the program with poorer scores on discipline, mother-child relationship quality, and externalizing problems.

  18. The mediation procedure in Romania

    Alexandrina Zaharia

    2009-06-01

    Full Text Available The mediation activity as an alternative way of solving conflicts occupies an important place in modernsociety. Currently, the mediation reached its maturity worldwide being adopted without reservations.The future of solving conflicts is undoubtedly closely related to mediation. XXth century is the century of solvingconflicts amiably outside the court room. In Romania and the mediation profession were regulated by the Law no.192/2006, on the basis of the idea that mediation is one of the major themes of the reform strategy of the judicialsystem 2005-2007. By adopting the mentioned law it was followed the idea of reducing the volume of activitycourts, and therefore, relieve them of as many cases, with the direct effect on the quality of justice. Mediation is avoluntary process in which the parties with a neutral and impartial third party, without power of decision - themediator - who is qualified to assist the parties to negotiate, facilitating the communication between them andhelping them to reach a unanimous effective and sustainable agreement. The parties may resort to mediation beforeor after triggering a trial. Mediation can be applied, in principle, on any type of conflict. However, theRomanian legislator has established special stipulations on conflict mediation in criminal, civil and familylaw. Although not expressly provided, the stipulations regarding the civil conflicts and also apply to commercialconflicts. Therefore, the mediation is applicable to most types of lawsuits, except those relating to personalrights. As a "win- win" principle, the mediation does not convert any of the parties defeated or victorious; allthose involved have gained by applying this procedure.

  19. Human milk proresolving mediators stimulate resolution of acute inflammation.

    Arnardottir, Hildur; Orr, Sarah K; Dalli, Jesmond; Serhan, Charles N

    2016-05-01

    Human milk contains nutrients and bioactive products relevant to infant development and immunological protection. Here, we investigated the proresolving properties of milk using human milk lipid mediator isolates (HLMIs) and determined their impact on resolution programs in vivo and with human macrophages. HLMIs reduced the maximum neutrophil numbers (14.6±1.2 × 10(6)-11.0±1.0 × 10(6) cells per exudate) and shortened the resolution interval (Ri; 50% neutrophil reduction) by 54% compared with peritonitis. Using rigorous liquid-chromatography tandem-mass spectrometry (LC-MS-MS)-based lipid mediator (LM) metabololipidomics, we demonstrated that human milk possesses a proresolving LM-specialized proresolving mediator (LM-SPM) signature profile, containing SPMs (e.g. resolvins (Rv), protectins (PDs), maresins (MaRs), and lipoxins (LXs)) at bioactive levels (pico-nanomolar concentrations) that enhanced human macrophage efferocytosis and bacterial containment. SPMs identified in human milk included D-series Rvs (e.g., RvD1, RvD2, RvD3, AT-RvD3, and RvD4), PD1, MaR1, E-series Rvs (e.g. RvE1, RvE2, and RvE3), and LXs (LXA4 and LXB4). Of the SPMs identified in human milk, RvD2 and MaR1 (50 ng per mouse) individually shortened Ri by ∼75%. Milk from mastitis gave higher leukotriene B4 and prostanoids and lower SPM levels. Taken together, these findings provide evidence that human milk has proresolving actions via comprehensive LM-SPM profiling, describing a potentially novel mechanism in maternal-infant biochemical imprinting.

  20. Family Functioning and Adolescent Alcohol Use: A Moderated Mediation Analysis

    Ohannessian, Christine McCauley; Flannery, Kaitlin M.; Simpson, Emily; Russell, Beth S.

    2016-01-01

    The primary goals of this longitudinal study were to examine the relationship between family functioning and adolescent alcohol use and to examine whether depressed mood mediates this relationship. An additional goal was to explore whether these relations were moderated by gender. The sample included 1,031 high school students from the Mid-Atlantic United States. Participants completed surveys in school during the spring of 2007, 2008, and 2009. Path analysis results indicated that family functioning predicted alcohol use for girls. Moreover, depressed mood mediated this relationship. None of the direct paths between family functioning and adolescent alcohol use were significant for boys. However, similar to girls, depressed mood negatively predicted alcohol use for boys. Taken together, the findings highlight the need for prevention programs targeting adolescent substance use to consider gender-specific trajectories. PMID:26994346

  7. Are mediation clauses binding and mandatory?

    Constantinescu Miruna

    2017-06-01

    Full Text Available This study analyses the legal force of mediation clauses in the common law systems and civil law systems with a main focus on the Romanian approach. First, the introductory section illustrates the paradox between the concept of binding and mandatory effect and the mediation mechanism, a voluntary manner to settle disputes. Notwithstanding, the possibility to coerce the parties to engage into a mediation, the voluntary character of the process is illustrated by the parties’ freedom to decide whether they settle or not. Second, the role of mediation clause is analysed and its advantages are briefly described. Third, the non-compliance of the prior mediation mechanism is presented, the starting point of the discussion being represented by the manner in which the parties drafted the mediation clause. A carefully drafted mediation clause, reflecting the parties’ consent, can determine a court or an arbitral tribunal to enforce such clause. Fourth, the study ends by mentioning the approach adopted by different national courts, emphasizing the Romanian legal perspective.

    2015-04-01

    Immune mediated diseases of oral cavity are uncommon. The lesions may be self-limiting and undergo remission spontaneously. Among the immune mediated oral lesions the most important are lichen planus, pemphigus, erythema multiformi, epidermolysis bullosa, systemic lupus erythematosis. Cellular and humoral mediated immunity play a major role directed against epithelial and connective tissue in chronic and recurrent patterns. Confirmatory diagnosis can be made by biopsy, direct and indirect immunoflouresence, immune precipitation and immunoblotting. Therapeutic agents should be selected after thorough evaluation of immune status through a variety of tests and after determining any aggravating or provoking factors. Early and appropriate diagnosis is important for proper treatment planning contributing to better prognosis and better quality of life of patient.

  13. Causal mediation analysis with multiple causally non-ordered mediators.

    Taguri, Masataka; Featherstone, John; Cheng, Jing

    2018-01-01

    In many health studies, researchers are interested in estimating the treatment effects on the outcome around and through an intermediate variable. Such causal mediation analyses aim to understand the mechanisms that explain the treatment effect. Although multiple mediators are often involved in real studies, most of the literature considered mediation analyses with one mediator at a time. In this article, we consider mediation analyses when there are causally non-ordered multiple mediators. Even if the mediators do not affect each other, the sum of two indirect effects through the two mediators considered separately may diverge from the joint natural indirect effect when there are additive interactions between the effects of the two mediators on the outcome. Therefore, we derive an equation for the joint natural indirect effect based on the individual mediation effects and their interactive effect, which helps us understand how the mediation effect works through the two mediators and relative contributions of the mediators and their interaction. We also discuss an extension for three mediators. The proposed method is illustrated using data from a randomized trial on the prevention of dental caries.

  14. Mediation –Voluntary or Mandatory Procedure

    Full Text Available Part of modifications brought through 370/2009 Act to the 192/2006 Law concerning mediation and structure of mediator profession have been interpreted as establishing a preliminary mediation procedure before intimating the courts of law, in civil and commercial matters. This interpretation is in excess of operative legal provisions. Although the law in modified form stipulates the compulsoriness of judicial authorities and other jurisdictional bodies to inform the parties about the possibility and the dvantages of using mediation procedure and the obligation to guide the parties to resort at mediation, this circumstances does not affect the mediation particular voluntary nature.

  16. Conflict Resolution in the Clinical Setting: A Story Beyond Bioethics Mediation.

    Morreim, Haavi

    2015-01-01

    Because ethics consults are often more about conflict than moral puzzlement, the skills of conflict resolution and communication facilitation are now deemed a core competency for ethics consultants. Those skills range beyond the traditional ambit of "bioethics mediation," as illustrated here by a recent mediation regarding a difficult discharge. As conflict permeates healthcare, often spawning downstream ethical issues, conflict resolution services might be deemed a genre of preventive ethics suitably offered by ethics committees. If so, a strong distinction must be made. "Bioethics mediation" as historically defined is a curious amalgam between a consultant who recommends, and a mediator who facilitates consensus among the parties at the table. On closer examination this approach is problematic, particularly in the clinical setting. A mediator who acts as consultant, telling parties what they should do or directly circumscribing the limits of an "acceptable" decision, quickly becomes just another pair of fists in the fight. At that point the odds for reaching genuine agreement, as opposed to a transient acquiescence, diminish markedly. Accordingly, those who undertake conflict resolution in the clinical setting need to distinguish quite sharply between facilitative mediation, versus a consultant's role. © 2015 American Society of Law, Medicine & Ethics, Inc.

  17. Mediation analysis with time varying exposures and mediators.

    VanderWeele, Tyler J; Tchetgen Tchetgen, Eric J

    2017-06-01

    In this paper we consider causal mediation analysis when exposures and mediators vary over time. We give non-parametric identification results, discuss parametric implementation, and also provide a weighting approach to direct and indirect effects based on combining the results of two marginal structural models. We also discuss how our results give rise to a causal interpretation of the effect estimates produced from longitudinal structural equation models. When there are time-varying confounders affected by prior exposure and mediator, natural direct and indirect effects are not identified. However, we define a randomized interventional analogue of natural direct and indirect effects that are identified in this setting. The formula that identifies these effects we refer to as the "mediational g-formula." When there is no mediation, the mediational g-formula reduces to Robins' regular g-formula for longitudinal data. When there are no time-varying confounders affected by prior exposure and mediator values, then the mediational g-formula reduces to a longitudinal version of Pearl's mediation formula. However, the mediational g-formula itself can accommodate both mediation and time-varying confounders and constitutes a general approach to mediation analysis with time-varying exposures and mediators.

  20. Cultural mediation in museums

    Gherghina Boda

    2017-12-01

    Full Text Available If we perceive the museum not only as a place of storing and conserving the patrimony, but also of transmitting it, then we can also see it as a mediator through which cultures can become collective patrimony. Tightly connected to patrimonial appropriation, mediation appears from this perspective as a process and not an end, as it manifests itself in animation, communication and making knowledge popular in relation to a precise patrimony. That is why we can see cultural mediation as a transmission, as a transformation, as an action or social project which aims at creating social bonds, the museum thus being not only a place of meeting for the public with the objects exposed, but also as a place of meeting between different cultures. Thus, cultural mediation presents itself as the most efficient means for access to culture of all categories of the public, situated as the crossroads of culture, continuous education and entertainment and is inscribed in the field of informal education.

  1. The Bensberg Mediation Model

    Full Text Available The basis of the conflict through the mediation represents the objectives and procedures ofmediation, mediation of a conflict. The conflict will not be disclosed to others, but the parties will be creditedthe authority to resolve the conflict, the conflict among themselves with the help of a mediator. The disputeshould be resolved by the parties with help of a third party. The parties in conflict (it may be several personsare jointly responsible for the solution. They seek together a way that leads to long-term settlement of theconflict. The assumption of responsibility in this process strengthens the confidence and the importance oftheir decision. Important is that losers usually have no peace, because they are out for revenge. Winners don’tneed peace. If both parties lose, remains disappointing, with the understanding of which the conflict isresolved, will understand each other better developed. Reconciliation is therefore a longer-term goal.Conflicts also help to clarify roles. The paper presents Bensberg Model of Mediation, because this isdeveloped as a win win solution and his possible implementation in Romanian schools.

  2. Axionic mirage mediation

    Nakamura, Shuntaro; Okumura, Ken-ichi; Yamaguchi, Masahiro

    2008-01-01

    Although mirage mediation is one of the most plausible mediation mechanisms of supersymmetry breaking, it suffers from two crucial problems. One is the μ/Bμ problem, and the second is the cosmological one. The former stems from the fact that the B parameter tends to be comparable with the gravitino mass, which is 2 orders of magnitude larger than the other soft masses. The latter problem is caused by the decay of the modulus whose branching ratio into the gravitino pair is sizable. In this paper, we propose a model of mirage mediation, in which Peccei-Quinn symmetry is incorporated. In this axionic mirage mediation, it is shown that the Peccei-Quinn symmetry breaking scale is dynamically determined around 10 10 GeV to 10 12 GeV due to the supersymmetry breaking effects, and the μ problem can be solved naturally. Furthermore, in our model, the lightest supersymmetric particle (LSP) is the axino, that is, the superpartner of the axion. The overabundance of the LSPs due to decays of the modulus/gravitino, which is the most serious cosmological difficulty in the mirage mediation, can be avoided if the axino is sufficiently light. The next-LSPs (NLSPs) produced by the gravitino decay eventually decay into the axino LSPs, yielding the dominant component of the axinos remaining today. It is shown that the axino with a mass of O(100) MeV is naturally realized, which can constitute the dark matter of the Universe, with a free-streaming length of the order of 0.1 Mpc. The saxion, the real scalar component of the axion supermultiplet, can also be cosmologically harmless due to the dilution of the modulus decay. The lifetime of the NLSP is relatively long, but much shorter than 1 sec, when the big-bang nucleosynthesis commences. The decay of the NLSP would provide intriguing collider signatures

  3. Interventional Effects for Mediation Analysis with Multiple Mediators.

    Vansteelandt, Stijn; Daniel, Rhian M

    2017-03-01

    The mediation formula for the identification of natural (in)direct effects has facilitated mediation analyses that better respect the nature of the data, with greater consideration of the need for confounding control. The default assumptions on which it relies are strong, however. In particular, they are known to be violated when confounders of the mediator-outcome association are affected by the exposure. This complicates extensions of counterfactual-based mediation analysis to settings that involve repeatedly measured mediators, or multiple correlated mediators. VanderWeele, Vansteelandt, and Robins introduced so-called interventional (in)direct effects. These can be identified under much weaker conditions than natural (in)direct effects, but have the drawback of not adding up to the total effect. In this article, we adapt their proposal to achieve an exact decomposition of the total effect, and extend it to the multiple mediator setting. Interestingly, the proposed effects capture the path-specific effects of an exposure on an outcome that are mediated by distinct mediators, even when-as often-the structural dependence between the multiple mediators is unknown, for instance, when the direction of the causal effects between the mediators is unknown, or there may be unmeasured common causes of the mediators.

  4. Mediation analysis with multiple versions of the mediator.

    Vanderweele, Tyler J

    2012-05-01

    The causal inference literature has provided definitions of direct and indirect effects based on counterfactuals that generalize the approach found in the social science literature. However, these definitions presuppose well-defined hypothetical interventions on the mediator. In many settings, there may be multiple ways to fix the mediator to a particular value, and these various hypothetical interventions may have very different implications for the outcome of interest. In this paper, we consider mediation analysis when multiple versions of the mediator are present. Specifically, we consider the problem of attempting to decompose a total effect of an exposure on an outcome into the portion through the intermediate and the portion through other pathways. We consider the setting in which there are multiple versions of the mediator but the investigator has access only to data on the particular measurement, not information on which version of the mediator may have brought that value about. We show that the quantity that is estimated as a natural indirect effect using only the available data does indeed have an interpretation as a particular type of mediated effect; however, the quantity estimated as a natural direct effect, in fact, captures both a true direct effect and an effect of the exposure on the outcome mediated through the effect of the version of the mediator that is not captured by the mediator measurement. The results are illustrated using 2 examples from the literature, one in which the versions of the mediator are unknown and another in which the mediator itself has been dichotomized.

  5. Mediation in Legal English Teaching

    Chovancová Barbora

    2016-06-01

    Full Text Available Mediation is a language activity that has been unjustly neglected when preparing law students for their future professional careers. When trained in a professional context, students need to develop and improve complex communicative skills. These include not only the traditional language skills such as reading, writing, listening and speaking, but also more advanced skills such as summarizing, providing definitions, changing registers etc. All these are involved in the students’ acquisition of ‘soft skills’ that are particularly important for students of law since much of their future work involves interpersonal lawyer-client interaction. This article argues that mediation is a crucial (though previously underestimated skill and that law-oriented ESP instruction should provide training aimed at developing this skill. Showing a practical application of this approach, the paper demonstrates that mediation can be successfully integrated in the legal English syllabus and make the learning of legal English more effective.

  12. mma: An R Package for Mediation Analysis with Multiple Mediators

    Qingzhao Yu

    2017-04-01

    Full Text Available Mediation refers to the effect transmitted by mediators that intervene in the relationship between an exposure and a response variable. Mediation analysis has been broadly studied in many fields. However, it remains a challenge for researchers to consider complicated associations among variables and to differentiate individual effects from multiple mediators. [1] proposed general definitions of mediation effects that were adaptable to all different types of response (categorical or continuous, exposure, or mediation variables. With these definitions, multiple mediators of different types can be considered simultaneously, and the indirect effects carried by individual mediators can be separated from the total effect. Moreover, the derived mediation analysis can be performed with general predictive models. That is, the relationships among variables can be modeled using not only generalized linear models but also nonparametric models such as the Multiple Additive Regression Trees. Therefore, more complicated variable transformations and interactions can be considered in analyzing the mediation effects. The proposed method is realized by the R package 'mma'. We illustrate in this paper the proposed method and how to use 'mma' to estimate mediation effects and make inferences.

  13. Causal Mediation Analysis of Survival Outcome with Multiple Mediators.

    Huang, Yen-Tsung; Yang, Hwai-I

    2017-05-01

    Mediation analyses have been a popular approach to investigate the effect of an exposure on an outcome through a mediator. Mediation models with multiple mediators have been proposed for continuous and dichotomous outcomes. However, development of multimediator models for survival outcomes is still limited. We present methods for multimediator analyses using three survival models: Aalen additive hazard models, Cox proportional hazard models, and semiparametric probit models. Effects through mediators can be characterized by path-specific effects, for which definitions and identifiability assumptions are provided. We derive closed-form expressions for path-specific effects for the three models, which are intuitively interpreted using a causal diagram. Mediation analyses using Cox models under the rare-outcome assumption and Aalen additive hazard models consider effects on log hazard ratio and hazard difference, respectively; analyses using semiparametric probit models consider effects on difference in transformed survival time and survival probability. The three models were applied to a hepatitis study where we investigated effects of hepatitis C on liver cancer incidence mediated through baseline and/or follow-up hepatitis B viral load. The three methods show consistent results on respective effect scales, which suggest an adverse estimated effect of hepatitis C on liver cancer not mediated through hepatitis B, and a protective estimated effect mediated through the baseline (and possibly follow-up) of hepatitis B viral load. Causal mediation analyses of survival outcome with multiple mediators are developed for additive hazard and proportional hazard and probit models with utility demonstrated in a hepatitis study.

  14. Immune mediated liver failure.

    Wang, Xiaojing; Ning, Qin

    2014-01-01

    Liver failure is a clinical syndrome of various etiologies, manifesting as jaundice, encephalopathy, coagulopathy and circulatory dysfunction, which result in subsequent multiorgan failure. Clinically, liver failure is classified into four categories: acute, subacute, acute-on-chronic and chronic liver failure. Massive hepatocyte death is considered to be the core event in the development of liver failure, which occurs when the extent of hepatocyte death is beyond the liver regenerative capacity. Direct damage and immune-mediated liver injury are two major factors involved in this process. Increasing evidence has suggested the essential role of immune-mediated liver injury in the pathogenesis of liver failure. Here, we review the evolved concepts concerning the mechanisms of immune-mediated liver injury in liver failure from human and animal studies. Both innate and adaptive immunity, especially the interaction of various immune cells and molecules as well as death receptor signaling system are discussed. In addition, we highlight the concept of "immune coagulation", which has been shown to be related to the disease progression and liver injury exacerbation in HBV related acute-on-chronic liver failure.

  15. Lopsided Gauge Mediation

    De Simone, Andrea; Giudice, Gian Francesco; Pappadopulo, Duccio; Rattazzi, Riccardo

    2011-01-01

    It has been recently pointed out that the unavoidable tuning among supersymmetric parameters required to raise the Higgs boson mass beyond its experimental limit opens up new avenues for dealing with the so called $\\mu$-$B_\\mu$ problem of gauge mediation. In fact, it allows for accommodating, with no further parameter tuning, large values of $B_\\mu$ and of the other Higgs-sector soft masses, as predicted in models where both $\\mu$ and $B_\\mu$ are generated at one-loop order. This class of models, called Lopsided Gauge Mediation, offers an interesting alternative to conventional gauge mediation and is characterized by a strikingly different phenomenology, with light higgsinos, very large Higgs pseudoscalar mass, and moderately light sleptons. We discuss general parametric relations involving the fine-tuning of the model and various observables such as the chargino mass and the value of $\\tan\\beta$. We build an explicit model and we study the constraints coming from LEP and Tevatron. We show that in spite of ne...

  17. What carries a mediation process? Configural analysis of mediation.

    von Eye, Alexander; Mun, Eun Young; Mair, Patrick

    2009-09-01

    Mediation is a process that links a predictor and a criterion via a mediator variable. Mediation can be full or partial. This well-established definition operates at the level of variables even if they are categorical. In this article, two new approaches to the analysis of mediation are proposed. Both of these approaches focus on the analysis of categorical variables. The first involves mediation analysis at the level of configurations instead of variables. Thus, mediation can be incorporated into the arsenal of methods of analysis for person-oriented research. Second, it is proposed that Configural Frequency Analysis (CFA) can be used for both exploration and confirmation of mediation relationships among categorical variables. The implications of using CFA are first that mediation hypotheses can be tested at the level of individual configurations instead of variables. Second, this approach leaves the door open for different types of mediation processes to exist within the same set. Using a data example, it is illustrated that aggregate-level analysis can overlook mediation processes that operate at the level of individual configurations.

  18. Video-mediated communication to support distant family connectedness.

    Furukawa, Ryoko; Driessnack, Martha

    2013-02-01

    It can be difficult to maintain family connections with geographically distant members. However, advances in computer-human interaction (CHI) systems, including video-mediated communication (VMC) are emerging. While VMC does not completely substitute for physical face-to-face communication, it appears to provide a sense of virtual copresence through the addition of visual and contextual cues to verbal communication between family members. The purpose of this study was to explore current patterns of VMC use, experiences, and family functioning among self-identified VMC users separated geographically from their families. A total of 341 participants (ages 18 to above 70) completed an online survey and Family APGAR. Ninty-six percent of the participants reported that VMC was the most common communication method used and 60% used VMC at least once/week. The most common reason cited for using VMC over other methods of communication was the addition of visual cues. A significant difference between the Family APGAR scores and the number of positive comments about VMC experience was also found. This exploratory study provides insight into the acceptance of VMC and its usefulness in maintaining connections with distant family members.

  1. DNA-Mediated Electrochemistry

    Gorodetsky, Alon A.; Buzzeo, Marisa C.

    2009-01-01

    The base pair stack of DNA has been demonstrated as a medium for long range charge transport chemistry both in solution and at DNA-modified surfaces. This chemistry is exquisitely sensitive to structural perturbations in the base pair stack as occur with lesions, single base mismatches, and protein binding. We have exploited this sensitivity for the development of reliable electrochemical assays based on DNA charge transport at self-assembled DNA monolayers. Here we discuss the characteristic features, applications, and advantages of DNA-mediated electrochemistry. PMID:18980370

    We discuss gravitational backgrounds where supersymmetry is broken at the end of a warped throat, and the SUSY-breaking is transmitted to the Standard Model via gauginos which live in (part of) the bulk of the throat geometry. We find that the leading effect arises from splittings of certain 'messenger mesons,' which are adjoint KK-modes of the D-branes supporting the Standard Model gauge group. This picture is a gravity dual of a strongly coupled field theory where SUSY is broken in a hidden sector and transmitted to the Standard Model via a relative of semi-direct gauge mediation.

  3. Mediation of Family Alcoholism Risk by Religious Affiliation Types*

    Haber, Jon Randolph; Jacob, Theodore

    2009-01-01

    Objective: Religious affiliation is inversely associated with alcohol dependence (AD). Our previous findings indicated that when a religious affiliation differentiated itself from cultural norms, then high-risk adolescents (those having parents with alcoholism history) raised with these affiliations exhibited fewer AD symptoms compared with adolescents of other religious affiliations and nonreligious adolescents. The first of two studies reported here provides a needed replication of our previous findings for childhood religious affiliation using a different sample, and the second study extends examination to current religious affiliation. Method: A national sample of male and female adolescents/young adults (N = 1,329; mean age = 19.6 years) was selected who were the offspring of members of the Vietnam Era Twin Registry. Parental alcoholism, religious affiliation types, and their interactions were examined as predictors of offspring AD symptoms. Results: (1) Offspring reared with a differentiating religious affiliation during childhood exhibited significantly fewer AD symptoms as young adults; (2) offspring with current differentiating religious affiliation also exhibited fewer AD symptoms; this main effect was not weakened by adding other measures of religiousness to the model; (3) differentiating religious affiliation was correlated with both family alcoholism risk and offspring outcome, and removed the association between family alcoholism risk and offspring outcome, thus indicating that differentiating religious affiliation was at least a partial mediator of the association between family AD history risk and offspring AD outcome. Conclusions: Current results indicate that religious differentiation is an inverse mediator of alcoholism risk for offspring with or without parental AD history and regardless of the influence of other religion variables. Results replicated our previous report on religious upbringing between ages 6 and 13 years and indicated an even

  4. Elder mediation in theory and practice: study results from a national caregiver mediation demonstration project.

    Crampton, Alexandra

    2013-01-01

    Mediation is a process through which a third party facilitates discussion among disputing parties to help them identify interests and ideally reach an amicable solution. Elder mediation is a growing subspecialty to address conflicts involving older adults, primarily involving caregiving or finances. Mediation is theorized to empower participants but critics argue that it can exacerbate power imbalances among parties and coerce consensus. These contested claims are examined through study of a national caregiver mediation demonstration project. Study implications underscore the importance of gerontological social work expertise to ensure the empowerment of vulnerable older adults in mediation sessions.

  6. The role of mediation in resolving workplace relationship conflict.

    McKenzie, Donna Margaret

    2015-01-01

    Stress triggered by workplace-based interpersonal conflict can result in damaged relationships, loss of productivity, diminished job satisfaction and increasingly, workers' compensation claims for psychological injury. This paper examined the literature on the role and effectiveness of mediation, as the most common method of Alternative Dispute Resolution, in resolving workplace relationship conflict. Available evidence suggests that mediation is most effective when supported by organisational commitment to ADR strategies, policies and processes, and conducted by independent, experienced and qualified mediators. The United States Postal Service program REDRESS™ is described as an illustration of the successful use of mediation to resolve conflict in the workplace. Copyright © 2015 Elsevier Ltd.

  7. Interventional effects for mediation analysis with multiple mediators

    Vansteelandt, Stijn; Daniel, Rhian M.

    2017-01-01

    The mediation formula for the identification of natural (in)direct effects has facilitated mediation analyses that better respect the nature of the data, with greater consideration of the need for confounding control. The default assumptions on which it relies are strong, however. In particular, they are known to be violated when confounders of the mediator–outcome association are affected by the exposure. This complicates extensions of counterfactual-based mediation analysis to settings that...

    2015-05-01

    The global movements of healthcare professionals and patient populations have increased the complexities of medical interactions at the point of service. This study examines interpreter mediated talk in cross-cultural general dentistry in Hong Kong where assisting para-professionals, in this case bilingual or multilingual Dental Surgery Assistants (DSAs), perform the dual capabilities of clinical assistant and interpreter. An initial language use survey was conducted with Polyclinic DSAs (n = 41) using a logbook approach to provide self-report data on language use in clinics. Frequencies of mean scores using a 10-point visual analogue scale (VAS) indicated that the majority of DSAs spoke mainly Cantonese in clinics and interpreted for postgraduates and professors. Conversation Analysis (CA) examined recipient design across a corpus (n = 23) of video-recorded review consultations between non-Cantonese speaking expatriate dentists and their Cantonese L1 patients. Three patterns of mediated interpreting indicated were: dentist designated expansions; dentist initiated interpretations; and assistant initiated interpretations to both the dentist and patient. The third, rather than being perceived as negative, was found to be framed either in response to patient difficulties or within the specific task routines of general dentistry. The findings illustrate trends in dentistry towards personalized care and patient empowerment as a reaction to product delivery approaches to patient management. Implications are indicated for both treatment adherence and the education of dental professionals. Copyright © 2015 Elsevier Ltd. All rights reserved.

  9. A school peer mediation program as a context for exploring therapeutic jurisprudence (TJ): Can a peer mediation program inform the law?

    McWilliam, Nicky

    2010-01-01

    This paper reports an exploratory study of a school peer mediation program implemented as an alternative way to manage bullying and other destructive conflict. The study explores the effects of the program on the well-being of members of the school community by examining perceptions of students, staff and a sample of parents and former students. Drawing on therapeutic jurisprudence (TJ) the study explores whether the component parts of the program, separately or together, promote intended or unintended therapeutic effects. The preliminary findings of the study emphasise the importance of peer mediation training and suggest that existing scholarship in the area of school conflict resolution and peer mediation, when viewed through a TJ lens, may provide valuable insights into how to optimally configure programs for development and adoption in schools and other community settings. The study highlights the lack of attention paid by the legal system to valuable scholarship in the area of school conflict resolution and peer mediation, which may have implications for the understanding and development of legal processes and the law in general.

  10. Mediation Analysis: A Practitioner's Guide.

    VanderWeele, Tyler J

    2016-01-01

    This article provides an overview of recent developments in mediation analysis, that is, analyses used to assess the relative magnitude of different pathways and mechanisms by which an exposure may affect an outcome. Traditional approaches to mediation in the biomedical and social sciences are described. Attention is given to the confounding assumptions required for a causal interpretation of direct and indirect effect estimates. Methods from the causal inference literature to conduct mediation in the presence of exposure-mediator interactions, binary outcomes, binary mediators, and case-control study designs are presented. Sensitivity analysis techniques for unmeasured confounding and measurement error are introduced. Discussion is given to extensions to time-to-event outcomes and multiple mediators. Further flexible modeling strategies arising from the precise counterfactual definitions of direct and indirect effects are also described. The focus throughout is on methodology that is easily implementable in practice across a broad range of potential applications.

  11. BRIEF CONSIDERATIONS REGARDING MEDIATION IN CRIMINAL MATTERS

    LUMINITA DRAGNE

    2012-05-01

    Full Text Available Mediation is an alternative means of conflict resolution, is designed as a flexible procedure whose utility was observed in contrast to the deficiencies of the judiciary system. In the field of criminal law, mediation is part of the larger concept of the restorative justice whose aim is restoring the main victim in its rights. From this perspective, to the criminal process is intended, in principal, repairing of the victim's prejudice and, subsequently, to encourage the delinquent in taking responsibility and to acknowledge his guilt, and also to determine him to actively participate in repairing the damage caused. The ultimate goal of the process is giving back the delinquent to society and consequently, reducing the relapse. Romanian legislator has not taken this concept, and how it is regulated mediation in criminal matters is hesitant, cautious and ultimately ineffective. Specifically, in situations that will actually occur, victim-delinquent mediation will only take the form of "assisted reconciliation."

    Full Text Available Considering that mediation is a facilitating way to access the alternative solving of litigations in conciliatory terms, the study is encouraging using the mediation and providing a balanced relationship between mediation and judiciary procedures. As an aftermath of summary definition, we can say that role of mediation is to overcome the communicative barriers in order to solve the conflict and save the fact situation on both parts. The study aims at analyzing objectively all consequences of both solving ways of litigations: traditional one, through the law court and mediation, with the advantages derived from them (celerity vs. time consuming, expensive judiciary proceedings vs. low costs, etc.

    2014-01-01

    The "Fondazione IRCCS Istituto Nazionale dei Tumori" ( National Tumour Institute) in Milan (Italy) offers mediation services aimed at restoring communication between patients and healthcare professionals, when their relationship has been altered by a conflict during the diagnosis or treatment process. A method derived from transformative mediation is used. The purpose of mediation is not to examine clinical aspects, nor to identify who is right and who is wrong. Individual sessions are often sufficient to reduce litigation.

  20. Soluble lymphocytic mediators

    Pick, E.

    1974-01-01

    The effect of a number of drugs on the production of macrophage migration inhibitory factor (MIF) by antigen-stimulated sensitized guinea-pig lymph node cells was studied. The drugs were present during the entire culture period and eliminated from supernatants by dialysis. It was found that MIF secretion is inhibited by exogenous dibutyryl cyclic AMP and by theophylline and chlorphenesin, two agents raising the endogenous level of cyclic AMP. On the other hand, isoproterenol, which stimulates cyclic AMP generation in several tissues, did not block MIF production. The formation of the mediator was also suppressed by the microfilament-affecting drug, cytochalasin B. The microtubular disruptive agents, colchicine and vinblastine sulphate, did not influence MIF production. It is concluded that: (a) endogenous cyclic AMP may act as a regulator of MIF production; (b) the activity of contractile microfilaments is probably required for MIF formation; and (c) microtubules are not involved in the secretory process.

  1. Protein- mediated enamel mineralization

    Moradian-Oldak, Janet

    2012-01-01

    Enamel is a hard nanocomposite bioceramic with significant resilience that protects the mammalian tooth from external physical and chemical damages. The remarkable mechanical properties of enamel are associated with its hierarchical structural organization and its thorough connection with underlying dentin. This dynamic mineralizing system offers scientists a wealth of information that allows the study of basic principals of organic matrix-mediated biomineralization and can potentially be utilized in the fields of material science and engineering for development and design of biomimetic materials. This chapter will provide a brief overview of enamel hierarchical structure and properties as well as the process and stages of amelogenesis. Particular emphasis is given to current knowledge of extracellular matrix protein and proteinases, and the structural chemistry of the matrix components and their putative functions. The chapter will conclude by discussing the potential of enamel for regrowth. PMID:22652761

    We show that in supersymmetric axion models the axion supermultiplet obtains a sizable F-term due to a non-supersymmetric dynamics and it generally gives the gaugino masses comparable to the anomaly mediation contribution. Thus the gaugino mass relation predicted by the anomaly mediation effect can be significantly modified in the presence of axion to solve the strong CP problem.

  5. Theorizing with/out "Mediators".

    Roth, Wolff-Michael; Jornet, Alfredo

    2017-01-05

    Mediation is one of the most often cited concepts in current cultural-historical theory literature, in which cultural actions and artifacts are often characterized as mediators standing between situational stimuli and behavioral responses. Most often presented as a means to overcome Cartesian dualism between subject and object, and between individual and society, some scholars have nonetheless raised criticism suggesting that such mediators are problematic for a dialectical psychology that takes a unit analysis (monist) approach. In fact, Spinoza develops a monist theory of mind and body that goes without and even excludes every form of mediation. In this study, we follow up on the latter criticisms and explore what we consider to be problematic uses of the notion of mediation as an analytical construct in the literature. We elaborate an empirically grounded discussion on the ways the concept of mediation may lead to dualistic readings; and we offer an alternative account where the notion of mediator is not needed. We conclude discussing prospects for and implications of a cultural-historical theory where the notion of mediation no longer is invoked to account for human action and development.

  6. Comments on general gauge mediation

    Intriligator, Kenneth; Sudano, Matthew

    2008-01-01

    There has been interest in generalizing models of gauge mediation of supersymmetry breaking. As shown by Meade, Seiberg, and Shih (MSS), the soft masses of general gauge mediation can be expressed in terms of the current two-point functions of the susy-breaking sector. We here give a simple extension of their result which provides, for general gauge mediation, the full effective potential for squark pseudo-D-flat directions. The effective potential reduces to the sfermion soft masses near the origin, and the full potential, away from the origin, can be useful for cosmological applications. We also generalize the soft masses and effective potential to allow for general gauge mediation by Higgsed gauge groups. Finally, we discuss general gauge mediation in the limit of small F-terms, and how the results of MSS connect with the analytic continuation in superspace results, based on a spurion analysis.

  14. Microbially mediated mineral carbonation

    Power, I. M.; Wilson, S. A.; Dipple, G. M.; Southam, G.

    2010-12-01

    Mineral carbonation involves silicate dissolution and carbonate precipitation, which are both natural processes that microorganisms are able to mediate in near surface environments (Ferris et al., 1994; Eq. 1). (Ca,Mg)SiO3 + 2H2CO3 + H2O → (Ca,Mg)CO3 + H2O + H4SiO4 + O2 (1) Cyanobacteria are photoautotrophs with cell surface characteristics and metabolic processes involving inorganic carbon that can induce carbonate precipitation. This occurs partly by concentrating cations within their net-negative cell envelope and through the alkalinization of their microenvironment (Thompson & Ferris, 1990). Regions with mafic and ultramafic bedrock, such as near Atlin, British Columbia, Canada, represent the best potential sources of feedstocks for mineral carbonation. The hydromagnesite playas near Atlin are a natural biogeochemical model for the carbonation of magnesium silicate minerals (Power et al., 2009). Field-based studies at Atlin and corroborating laboratory experiments demonstrate the ability of a microbial consortium dominated by filamentous cyanobacteria to induce the precipitation of carbonate minerals. Phototrophic microbes, such as cyanobacteria, have been proposed as a means for producing biodiesel and other value added products because of their efficiency as solar collectors and low requirement for valuable, cultivable land in comparison to crops (Dismukes et al., 2008). Carbonate precipitation and biomass production could be facilitated using specifically designed ponds to collect waters rich in dissolved cations (e.g., Mg2+ and Ca2+), which would allow for evapoconcentration and provide an appropriate environment for growth of cyanobacteria. Microbially mediated carbonate precipitation does not require large quantities of energy or chemicals needed for industrial systems that have been proposed for rapid carbon capture and storage via mineral carbonation (e.g., Lackner et al., 1995). Therefore, this biogeochemical approach may represent a readily

  15. Nanoparticle mediated micromotor motion

    Liu, Mei; Liu, Limei; Gao, Wenlong; Su, Miaoda; Ge, Ya; Shi, Lili; Zhang, Hui; Dong, Bin; Li, Christopher Y.

    2015-03-01

    In this paper, we report the utilization of nanoparticles to mediate the motion of a polymer single crystal catalytic micromotor. Micromotors have been fabricated by directly self-assembling functional nanoparticles (platinum and iron oxide nanoparticles) onto one or both sides of two-dimensional polymer single crystals. We show that the moving velocity of these micromotors in fluids can be readily tuned by controlling the nanoparticles' surface wettability and catalytic activity. A 3 times velocity increase has been achieved for a hydrophobic micromotor as opposed to the hydrophilic ones. Furthermore, we demonstrate that the catalytic activity of platinum nanoparticles inside the micromotor can be enhanced by their synergetic interactions with iron oxide nanoparticles and an electric field. Both strategies lead to dramatically increased moving velocities, with the highest value reaching ~200 μm s-1. By decreasing the nanoparticles' surface wettability and increasing their catalytic activity, a maximum of a ~10-fold increase in the moving speed of the nanoparticle based micromotor can be achieved. Our results demonstrate the advantages of using nanoparticles in micromotor systems.In this paper, we report the utilization of nanoparticles to mediate the motion of a polymer single crystal catalytic micromotor.

    2014-01-01

    Using data from the NICHD Study of Early Child Care and Youth Development, we examined children’s internalizing and externalizing behavior problems from age 5 to age 15 in relation to whether they had experienced a parental divorce. Children from divorced families had more behavior problems compared with a propensity score-matched sample of children from intact families according to both teachers and mothers. They exhibited more internalizing and externalizing problems at the first assessment...

  4. History of the Institute of Mediation in India

    Ekaterina P. Rusakova

    2016-12-01

    Full Text Available In this article author studies history of the institute of mediation formation and development in India. In the process of research author emphasizes that as a consequence of India's rapid economic development, number of disputes that are associated with them inevitably increases. Mediation is one of the popular methods of resolving disputes these days. In conclusion author emphasizes that the place and role of mediation is explained not only by the modern business culture of this country, but also because from a long time the population preferred to resolve conflicts through negotiations and with the participation of mediators. And the fact that the ancient model of peaceful settlement of disputes has survived to this day is due to the high level of poverty, cultural and religious diversity, and the preservation of traditional and community values and norms. It can be stated that the use of mediation, among other things, including traditional forms of alternative dispute resolution, has had a beneficial effect on the Indian judicial system, both in resolving problems with excessive workload on courts, and in delaying the adjudication of disputes.

  5. Mediation of information and educational mediation: conceptual discussions

    Helena Célia de Souza Sacerdote

    2016-04-01

    Full Text Available Introduction: This is systematization of theoretical and methodological contributions related to the concepts of mediation information and pedagogical mediation in the literature. Objective: To understand possible intersection of information science and Online Education with regard to these concepts to check that both can be considered as analogous in its essence and practice. Methodology: Literature review based on literature by consulting the scientific productions selected in search of SciELO.ORG databases and EBSCO Host, the portal of CAPES / MEC and Google Scholar. Results: The most cited concepts in information science and education were de Almeida Junior (2009 and Masetto (2013, respectively. Conclusion: It is observed that the concept of mediation can move interchangeably between both areas. This is because the evidence found in the productions of the last five years indicate that the concept of information of mediation seems to have found its bases in education (educational psychology.

  9. Estimation of causal mediation effects for a dichotomous outcome in multiple-mediator models using the mediation formula.

    Wang, Wei; Nelson, Suchitra; Albert, Jeffrey M

    2013-10-30

    Mediators are intermediate variables in the causal pathway between an exposure and an outcome. Mediation analysis investigates the extent to which exposure effects occur through these variables, thus revealing causal mechanisms. In this paper, we consider the estimation of the mediation effect when the outcome is binary and multiple mediators of different types exist. We give a precise definition of the total mediation effect as well as decomposed mediation effects through individual or sets of mediators using the potential outcomes framework. We formulate a model of joint distribution (probit-normal) using continuous latent variables for any binary mediators to account for correlations among multiple mediators. A mediation formula approach is proposed to estimate the total mediation effect and decomposed mediation effects based on this parametric model. Estimation of mediation effects through individual or subsets of mediators requires an assumption involving the joint distribution of multiple counterfactuals. We conduct a simulation study that demonstrates low bias of mediation effect estimators for two-mediator models with various combinations of mediator types. The results also show that the power to detect a nonzero total mediation effect increases as the correlation coefficient between two mediators increases, whereas power for individual mediation effects reaches a maximum when the mediators are uncorrelated. We illustrate our approach by applying it to a retrospective cohort study of dental caries in adolescents with low and high socioeconomic status. Sensitivity analysis is performed to assess the robustness of conclusions regarding mediation effects when the assumption of no unmeasured mediator-outcome confounders is violated.

    The causal inference literature has provided definitions of direct and indirect effects based on counterfactuals that generalize the approach found in the social science literature. However, these definitions presuppose well defined hypothetical interventions on the mediator. In many settings there may be multiple ways to fix the mediator to a particular value and these different hypothetical interventions may have very different implications for the outcome of interest. In this paper we cons...

  14. Dimensional reduction in anomaly mediation

    Boyda, Ed; Murayama, Hitoshi; Pierce, Aaron

    2002-01-01

    We offer a guide to dimensional reduction in theories with anomaly-mediated supersymmetry breaking. Evanescent operators proportional to ε arise in the bare Lagrangian when it is reduced from d=4 to d=4-2ε dimensions. In the course of a detailed diagrammatic calculation, we show that inclusion of these operators is crucial. The evanescent operators conspire to drive the supersymmetry-breaking parameters along anomaly-mediation trajectories across heavy particle thresholds, guaranteeing the ultraviolet insensitivity

  15. Museum signage as distributed mediation to encourage family learning

    Kim, Kyungyoun

    Many prior studies conducted in museums have focused primarily on exhibits as the main objects for learning. Less progress has been made in studying signage as another meaning-making tool in museums. The present study was designed to understand the role of signage in family learning by answering the following research questions, "How does signage about exhibit content or interaction strategies affect parents' and children's learning and their engagement?" and "What is the role of parent prior knowledge on parents' and children's learning and their engagement?" To address these questions, 45 parent-child dyads with children aged six to seven years were recruited to engage with two exhibits about cars. Fifteen parent-child dyads were assigned to each of three conditions, created by two different types of signage: (1) Content and interaction signage condition, (2) Content signage condition, and (3) No signage condition. In each condition, eight parents with low knowledge in the car domain and seven parents with high knowledge were recruited. Findings showed that parents and children learned and engaged differently across the three signage conditions. Both children and parents in the conditions with signage learned more than children and parents in the no signage condition. By using information from signage, parents in the two signage conditions were able to identify the content of the exhibit more quickly and to shape appropriate educational messages in their conversations with children. Findings also showed that parents with high knowledge were more likely to have the exhibit-focused engagement, which was often oriented to their own interpretation and not always beneficial for children's learning. However, by showing that parent-child dyads in the content and interaction signage condition were most likely to operate and observe the exhibit appropriately and most likely to describe evidence and make appropriate inferences, this study suggested that the interaction

  15. Family Environments and Children's Executive Function: The Mediating Role of Children's Affective State and Stress.

    He, Zhong-Hua; Yin, Wen-Gang

    2016-09-01

    There is increasing evidence that inadequate family environments (family material environment and family psychosocial environment) are not only social problems but also factors contributing to adverse neurocognitive outcomes. In the present study, the authors investigated the relationship among family environments, children's naturalistic affective state, self-reported stress, and executive functions in a sample of 157 Chinese families. These findings revealed that in inadequate family material environments, reduced children's cognitive flexibility is associated with increased naturalistic negative affectivity and self-reported stress. In addition, naturalistic negative affectivity mediated the association between family expressiveness and children's cognitive flexibility. The authors used a structural equation model to examine the mediation model hypothesis, and the results confirmed the mediating roles of naturalistic negative affectivity and self-reported stress between family environments and the cognitive flexibility of Chinese children. These findings indicate the importance of reducing stress and negative emotional state for improving cognitive functions in children of low socioeconomic status.

  16. Gaugino-assisted anomaly mediation

    Kribs, Graham D.

    2001-01-01

    I present a model of supersymmetry breaking mediated through a small extra dimension. Standard model matter multiplets and a supersymmetry-breaking (or 'hidden') sector are confined to opposite four-dimensional boundaries while gauge multiplets live in the bulk. The hidden sector does not contain a singlet and the dominant contribution to gaugino masses is via anomaly-mediated supersymmetry breaking. Scalar masses get contributions from both anomaly mediation and a tiny hard breaking of supersymmetry by operators on the hidden-sector boundary. These operators contribute to scalar masses at one loop and in most of parameter space, their contribution dominates. Thus it is easy to make all squared scalar masses positive. As no additional fields or symmetries are required below the Planck scale, this is among the simplest working models of anomaly mediation. The gaugino spectrum is left untouched and the phenomenology of the model is roughly similar to anomaly mediated supersymmetry breaking with a universal scalar mass added. Finally, the main differences in the spectrum between this model and other approaches are identified. This talk is based on work [1] done in collaboration with David E. Kaplan

  18. SPECIAL ISSUES REGARDING THE MEDIATION PROCESS IN THE COMMERCIAL FIELD

    SEPTIMIU STOICA

    2012-05-01

    Full Text Available The purpose of the research subject to this paper is to find proper solutions for the increase of the volume and efficiency in the field of commercial mediation. Starting from practical remarks, after an analysis of the substance, a new concept is suggested to be included and put into operation, namely the special commercial mediation, and a plead is made for its use in the current activity of alternative dispute resolution. The first major objective of this paper is to demonstrate once again the need and utility of mediation in the commercial field, insisting though on its remarkable specific nature. The second objective is, starting from the outlined differences between the commercial mediation and the classical mediation, to define and to conceptualize the special commercial mediation, as a separate branch of mediation. The third objective of this paper is to draw the regime of the newly defined category of commercial mediation from a regulatory point of view, of the implementation structure and techniques as foreseen.

  19. Family boundary characteristics, work-family conflict and life satisfaction: A moderated mediation model.

    Qiu, Lin; Fan, Jinyan

    2015-10-01

    Although work-family border and boundary theory suggest individuals' boundary characteristics influence their work-family relationship, it is largely unknown how boundary flexibility and permeability mutually influence work-family conflict and subsequent employee outcomes. Moreover, the existing work-family conflict research has been mainly conducted in the United States and other Western countries. To address these gaps in the work-family literature, the present study examines a moderated mediation model regarding how family boundary characteristics may influence individuals' work-family conflict and life satisfaction with a sample of 278 Chinese full-time employees. Results showed that employees' family flexibility negatively related to their perceived work interference with family (WIF) and family interference with work (FIW), and both these two relationships were augmented by individuals' family permeability. In addition, WIF mediated the relationship between family flexibility and life satisfaction; the indirect effect of family flexibility on life satisfaction via WIF was stronger for individuals with higher family permeability. The theoretical and managerial implications of these findings are discussed. © 2014 International Union of Psychological Science.

  20. Work-family conflict and burnout among Chinese female nurses: the mediating effect of psychological capital.

    Wang, Yang; Chang, Ying; Fu, Jialiang; Wang, Lie

    2012-10-29

    Burnout among nurses not only threatens their own health, but also that of their patients. Exploring risk factors of nurse' burnout is important to improve nurses' health and to increase the quality of health care services. This study aims to explore the relationship between work-family conflict and burnout among Chinese female nurses and the mediating role of psychological capital in this relationship. This cross-sectional study was performed during the period of September and October 2010. A questionnaire that consisted of the Maslach Burnout Inventory-General Survey (MBI-GS), the work-family conflict scale and the psychological capital questionnaire (PCQ-24) scale, as well as demographic and working factors, was distributed to nurses in Liaoning province, China. A total of 1,332 individuals (effective response rate: 78.35%) became our subjects. Hierarchical linear regression analyses were performed to explore the mediating role of psychological capital. Both work interfering family conflict and family interfering work conflict were positively related with emotional exhaustion and cynicism. However, work interfering family conflict was positively related with professional efficacy whereas family interfering work conflict was negatively related with it. Psychological capital partially mediated the relationship of work interfering family conflict with emotional exhaustion and cynicism; and partially mediated the relationship of family interfering work conflict with emotional exhaustion, cynicism and professional efficacy. Work-family conflict had effects on burnout and psychological capital was a mediator in this relationship among Chinese nurses. Psychological capital was a positive resource for fighting against nurses' burnout.

    2016-03-15

    We propose a simple model of split supersymmetry from gauge mediation. This model features gauginos that are parametrically a loop factor lighter than scalars, accommodates a Higgs boson mass of 125 GeV, and incorporates a simple solution to the μ−b{sub μ} problem. The gaugino mass suppression can be understood as resulting from collective symmetry breaking. Imposing collider bounds on μ and requiring viable electroweak symmetry breaking implies small a-terms and small tan β — the stop mass ranges from 10{sup 5} to 10{sup 8} GeV. In contrast with models with anomaly + gravity mediation (which also predict a one-loop loop suppression for gaugino masses), our gauge mediated scenario predicts aligned squark masses and a gravitino LSP. Gluinos, electroweakinos and Higgsinos can be accessible at the LHC and/or future colliders for a wide region of the allowed parameter space.

  4. Radical-Mediated Enzymatic Polymerizations

    Zavada, Scott R.; Battsengel, Tsatsral; Scott, Timothy F.

    2016-01-01

    Polymerization reactions are commonly effected by exposing monomer formulations to some initiation stimulus such as elevated temperature, light, or a chemical reactant. Increasingly, these polymerization reactions are mediated by enzymes―catalytic proteins―owing to their reaction efficiency under mild conditions as well as their environmental friendliness. The utilization of enzymes, particularly oxidases and peroxidases, for generating radicals via reduction-oxidation mechanisms is especially common for initiating radical-mediated polymerization reactions, including vinyl chain-growth polymerization, atom transfer radical polymerization, thiol–ene step-growth polymerization, and polymerization via oxidative coupling. While enzyme-mediated polymerization is useful for the production of materials intended for subsequent use, it is especially well-suited for in situ polymerizations, where the polymer is formed in the place where it will be utilized. Such polymerizations are especially useful for biomedical adhesives and for sensing applications. PMID:26848652

  7. Surfactant-Mediated Growth Revisited

    Meyerheim, H. L.; Sander, D.; Popescu, R.; Pan, W.; Kirschner, J.; Popa, I.

    2007-01-01

    The x-ray structure analysis of the oxygen-surfactant-mediated growth of Ni on Cu(001) identifies up to 0.15 monolayers of oxygen in subsurface octahedral sites. This questions the validity of the general view that surfactant oxygen floats on top of the growing Ni film. Rather, the surfactant action is ascribed to an oxygen-enriched zone extending over the two topmost layers. Surface stress measurements support this finding. Our results have important implications for the microscopic understanding of surfactant-mediated growth and the change of the magnetic anisotropy of the Ni films

    Full Text Available As a space of sociability, virtual games, especially online role playing games, allow us to capture the interest of the playfulness in social life, but they are means by which users are able to experiment their relationship to others. The virtual games as a mediation device, constitute a "pretext" to forge friendships, develop love relationships, improve language skills, discover other cultures, etc. Based on a sociological survey of Tunisian Internet users (both sexes fans of virtual games we try to show how playful mediation is producing a multifaceted virtual sociality inherent in our contemporary societies.

  9. Dynamical Messengers for Gauge Mediation

    Hook, Anson; Torroba, Gonzalo; /SLAC /Stanford U., Phys. Dept.

    2011-08-17

    We construct models of indirect gauge mediation where the dynamics responsible for breaking supersymmetry simultaneously generates a weakly coupled subsector of messengers. This provides a microscopic realization of messenger gauge mediation where the messenger and hidden sector fields are unified into a single sector. The UV theory is SQCD with massless and massive quarks plus singlets, and at low energies it flows to a weakly coupled quiver gauge theory. One node provides the primary source of supersymmetry breaking, which is then transmitted to the node giving rise to the messenger fields. These models break R-symmetry spontaneously, produce realistic gaugino and sfermion masses, and give a heavy gravitino.

  10. How job demands affect absenteeism? The mediating role of work-family conflict and exhaustion.

    Vignoli, Michela; Guglielmi, Dina; Bonfiglioli, Roberta; Violante, Francesco Saverio

    2016-01-01

    To investigate how psychosocial factors (such as job demands and work-family conflict) produce absenteeism in the workplace, using the health impairment process of the job demands-resources model. According to this model, job demands lead to burnout (often measured with the emotional exhaustion component), which in turn could lead to outcomes (such as absenteeism). Work-family conflict (WFC) was also studied, because of contradictory results collected in the existing literature on absenteeism in the workplace, regarding the role of WFC in causing absenteeism. Data were collected on 245 workers using both subjective (questionnaire on psychological risk factors and work-related health) and objective data (sickness leave frequency records). To test the hypothesis that job demands and WFC contribute to absenteeism in the workplace, a subsequent mediation analysis was used, which analysed both (a) the subsequent mediation of WFC and emotional exhaustion and (b) the separate roles played by the mediators proposed (WFC and emotional exhaustion). Job demands affect absenteeism through the subsequent mediation of WFC and emotional exhaustion. In addition, emotional exhaustion mediates the relationship between job demands and absenteeism, while WFC does not. In conclusion, subsequent mediation highlights the role of emotional exhaustion in causing absenteeism; in fact, when emotional exhaustion is included in the analysis, job demands are associated with higher levels of absenteeism. The results of this study suggest that without the concurrent contribution of emotional exhaustion, WFC does not influence absenteeism in the workplace. Our findings are useful for organizations that aim to reduce absenteeism.

  11. Transporter-mediated biofuel secretion.

    Doshi, Rupak; Nguyen, Tuan; Chang, Geoffrey

    2013-05-07

    Engineering microorganisms to produce biofuels is currently among the most promising strategies in renewable energy. However, harvesting these organisms for extracting biofuels is energy- and cost-intensive, limiting the commercial feasibility of large-scale production. Here, we demonstrate the use of a class of transport proteins of pharmacological interest to circumvent the need to harvest biomass during biofuel production. We show that membrane-embedded transporters, better known to efflux lipids and drugs, can be used to mediate the secretion of intracellularly synthesized model isoprenoid biofuel compounds to the extracellular milieu. Transporter-mediated biofuel secretion sustainably maintained an approximate three- to fivefold boost in biofuel production in our Escherichia coli test system. Because the transporters used in this study belong to the ubiquitous ATP-binding cassette protein family, we propose their use as "plug-and-play" biofuel-secreting systems in a variety of bacteria, cyanobacteria, diatoms, yeast, and algae used for biofuel production. This investigation showcases the potential of expressing desired membrane transport proteins in cell factories to achieve the export or import of substances of economic, environmental, or therapeutic importance.

    2010-08-15

    We study anomaly mediated supersymmetry breaking in type IIB string theory and use our results to test the supergravity formula for anomaly mediated gaugino masses. We compute 1-loop gaugino masses for models of D3-branes on orbifold singularities with 3-form fluxes by calculating the annulus correlator of 3-form flux and two gauginos in the zero momentum limit. Consistent with supergravity expectations we find both anomalous and running contributions to 1-loop gaugino masses. For background Neveu-Schwarz H-flux we find an exact match with the supergravity formula. For Ramond-Ramond flux there is an off-shell ambiguity that precludes a full matching. The anomaly mediated gaugino masses, while determined by the infrared spectrum, arise from an explicit sum over UV open string winding modes. We also calculate brane-to-brane tree-level gravity mediated gaugino masses and show that there are two contributions coming from the dilaton and from the twisted modes, which are suppressed by the full T{sup 6} volume and the untwisted T{sup 2} volume respectively.

    The emerging power of thiol-mediated uptake with strained disulfides called for a move from sulfur to selenium. We report that according to results with fluorescent model substrates, cellular uptake with 1,2-diselenolanes exceeds uptake with 1,2-dithiolanes and epidithiodiketopiperazines with regard to efficiency as well as intracellular localization. The diselenide analog of lipoic acid performs best. This 1,2-diselenolane delivers fluorophores efficiently to the cytosol of HeLa Kyoto cells, without detectable endosomal capture as with 1,2-dithiolanes or dominant escape into the nucleus as with epidithiodiketopiperazines. Diselenolane-mediated cytosolic delivery is non-toxic (MTT assay), sensitive to temperature but insensitive to inhibitors of endocytosis (chlorpromazine, methyl-β-cyclodextrin, wortmannin, cytochalasin B) and conventional thiol-mediated uptake (Ellman's reagent), and to serum. Selenophilicity, the extreme CSeSeC dihedral angle of 0° and the high but different acidity of primary and secondary selenols might all contribute to uptake. Thiol-exchange affinity chromatography is introduced as operational mimic of thiol-mediated uptake that provides, in combination with rate enhancement of DTT oxidation, direct experimental evidence for existence and nature of the involved selenosulfides.

  19. Mediated Encryption: Analysis and Design

    2015-01-01

    Full Text Available Boneh, Ding and Tsudik presented identity-based mediated RSA encryption and signature systems in which the users are not allowed to decrypt/sign messages without the authorisation of a security mediator.We show that ID-MRSA is not secure and we present a secure modified version of it which is as efficient as the original system. We also propose a generic mediated encryption that translates any identity based encryption to a mediated version of this IBE. It envelops an IBE encrypted message using a user’s identity into an IBE envelope using the identity of the SEM. We present two security models based on the role of the adversary whether it is a revoked user or a hacked SEM. We prove that GME is as secure as the SEM’s IBE against a revoked user and as secure as the user’s IBE against a hacked SEM. We also present two implementations of GME based on Boneh-Franklin FullIBE system which is a pairing-based system and Boneh, Gentry and Hamburg (BGH system which is pairing-free system.

  5. Selective Modulation of Integrin-mediated Cell Migration by Distinct ADAM Family MembersV⃞

    Huang, Jing; Bridges, Lance C.; White, Judith M.

    2005-01-01

    A disintegrin and a metalloprotease (ADAM) family members have been implicated in many biological processes. Although it is recognized that recombinant ADAM disintegrin domains can interact with integrins, little is known about ADAM-integrin interactions in cellular context. Here, we tested whether ADAMs can selectively regulate integrin-mediated cell migration. ADAMs were expressed in Chinese hamster ovary cells that express defined integrins (α4β1, α5β1, or both), and cell migration on full-length fibronectin or on its α4β1 or α5β1 binding fragments was studied. We found that ADAMs inhibit integrin-mediated cell migration in patterns dictated by the integrin binding profiles of their isolated disintegrin domains. ADAM12 inhibited cell migration mediated by the α4β1 but not the α5β1 integrin. ADAM17 had the reciprocal effect; it inhibited α5β1- but not α4β1-mediated cell migration. ADAM19 and ADAM33 inhibited migration mediated by both α4β1 and α5β1 integrins. A point mutation in the ADAM12 disintegrin loop partially reduced the inhibitory effect of ADAM12 on cell migration on the α4β1 binding fragment of fibronectin, whereas mutations that block metalloprotease activity had no effect. Our results indicate that distinct ADAMs can modulate cell migration mediated by specific integrins in a pattern dictated, at least in part, by their disintegrin domains. PMID:16079176

  6. Examining Behavioural Coping Strategies as Mediators between Work-Family Conflict and Psychological Distress

    2015-01-01

    Full Text Available We examined the mediating role of behavioral coping strategies in the association between work-family conflict and psychological distress. In particular, we examined the two directions of work-family conflict, namely, work interference into family and family interference into work. Furthermore, two coping styles in this study were adaptive and maladaptive coping strategies. This cross-sectional study was conducted among 429 Malaysian working women using self-reported data. The results of mediational analysis in the present study showed that adaptive coping strategy does not significantly mediate the effect of work-family conflict on psychological distress. However, maladaptive coping strategies significantly mediate the effect of work-family conflict on psychological distress. These results show that adaptive coping strategies, which aimed to improve the stressful situation, are not effective in managing stressor such as work-family conflict. We found that experiencing interrole conflict steers employees toward frequent use of maladaptive coping strategies which in turn lead to psychological distress. Interventions targeted at improvement of coping skills which are according to individual’s needs and expectation may help working women to balance work and family demands. The important issue is to keep in mind that effective coping strategies are to control the situations not to eliminate work-family conflict.

    Experiments seeking to detect rare event interactions such as dark matter or coherent elastic neutrino nucleus scattering are striving for large mass detectors with very low detection threshold. Using Neganov-Luke phonon amplification effect, the Cryogenic Dark Matter Search (CDMS) experiment is reaching unprecedented RMS resolutions of ∼14 eV{sub ee}. CDMSlite is currently the most sensitive experiment to WIMPs of mass ∼5 GeV/c{sup 2} but is limited in achieving higher phonon gains due to an early onset of leakage current into Ge crystals. The contact interface geometry is particularly weak for blocking hole injection from the metal, and thus a new design is demonstrated that allows high voltage bias via vacuum separated electrode. With an increased bias voltage and a×2 Luke phonon gain, world best RMS resolution of sigma ∼7 eV{sub ee} for 0.25 kg (d=75 mm, h=1 cm) Ge detectors was achieved. Since the leakage current is a function of the field and the phonon gain is a function of the applied voltage, appropriately robust interface blocking material combined with thicker substrate (25 mm) will reach a resolution of ∼2.8 eV{sub ee}. In order to achieve better resolution of ∼ eV, we are investigating a layer of insulator between the phonon readout surface and the semiconductor crystals.

    2014-11-01

    Dyads of siblings in which the younger sibling had an intellectual disability (ID, n  =  25) were videotaped interacting. The ID group was compared with typically developing sibling dyads matched on mental age (n  =  25) and chronological age (n  =  25). We observed the mediation strategies, activation, and antimediation behaviors of older siblings and younger siblings' responsiveness to mediation. Mediation strategies were analyzed by the Observation of Mediation Interaction scale. The ID group scored highest on mediation strategies and lowest on activation and antimediation behaviors. Younger siblings' responsiveness to mediation was highest among the ID group. Mediation for Intentionality and Reciprocity and Meaning were positively associated with the verbal responsiveness of the younger siblings. Activation and antimediation behaviors were negatively associated with the verbal responsiveness.

  10. Emerging roles of eosinophils and eosinophil-derived lipid mediators in the resolution of inflammation

    Yosuke eIsobe

    2012-08-01

    Full Text Available Acute inflammation and its resolution are essential processes for tissue protection and homeostasis. Once thought to be a passive process, the resolution of inflammation is now shown to involve active biochemical programs that enable inflamed tissues to return to homeostasis. The mechanisms by which acute inflammation is resolved are of interest, and research in recent years has uncovered new endogenous anti-inflammatory and pro-resolving lipid mediators (i.e. lipoxins, resolvins, protectin, and maresin generated from polyunsaturated fatty acids (PUFAs. This review presents new insights into the cellular and molecular mechanisms of inflammatory resolution, especially the roles of eosinophils, and a series of omega-3 PUFA derived anti-inflammatory lipid mediators that they generate.

    2015-01-01

    Few longitudinal studies have examined the pathways through which family violence leads to dating aggression. In the current study the authors used 3 waves of data obtained from 8th- and 9th-grade adolescents (N = 1,965) to examine the hypotheses that the prospective relationship between witnessing family violence and directly experiencing violence and physical dating aggression perpetration is mediated by 3 constructs: (a) normative beliefs about dating aggression (norms), (b) anger dysregulation, and (c) depression. Results from cross-lagged regression models suggest that the relationship between having been hit by an adult and dating aggression is mediated by changes in norms and anger dysregulation, but not depression. No evidence of indirect effects from witnessing family violence to dating aggression was found through any of the proposed mediators. Taken together, the findings suggest that anger dysregulation and normative beliefs are potential targets for dating abuse prevention efforts aimed at youth who have directly experienced violence.

  17. Antimicrobial aspects of inflammatory resolution in the mucosa: A role for pro-resolving mediators1

    Campbell, Eric L.; Serhan, Charles N.; Colgan, Sean P.

    2011-01-01

    Mucosal surfaces function as selectively permeable barriers between the host and the outside world. Given their close proximity to microbial antigens, mucosal surfaces have evolved sophisticated mechanisms for maintaining homeostasis and preventing excessive acute inflammatory reactions. The role attributed to epithelial cells was historically limited to serving as a selective barrier, in recent years numerous findings implicate an active role of the epithelium with pro-resolving mediators in the maintenance of immunological equilibrium. In this brief review, we highlight new evidence that the epithelium actively contributes to coordination and resolution of inflammation, principally through the generation of anti-inflammatory and pro-resolution lipid mediators. These autacoids, derived from ω-6 and ω-3 polyunsaturated fatty acids, are implicated in the initiation, progression and resolution of acute inflammation and display specific, epithelial-directed actions focused on mucosalhomeostasis. We also summarize present knowledge of mechanisms for resolution via regulation of epithelial-derived antimicrobial peptides in response to pro-resolving lipid mediators. PMID:21934099

  19. Work-family conflict and burnout among Chinese doctors: the mediating role of psychological capital.

    Wang, Yang; Liu, Li; Wang, Jiana; Wang, Lie

    2012-01-01

    The aim of this study was to investigate the relation between work-family conflict and burnout, and the mediating role of psychological capital (PsyCap) in the relation between work-family conflict and burnout, among Chinese doctors. This cross-sectional study was performed during the period of September/October 2010. A questionnaire that comprised work-family conflict assessed by the work-family conflict scale, PsyCap assessed by the PCQ-24 scale and burnout assessed by the Maslach Burnout Inventory-General Survey (MBI-GS), as well as age and gender, was distributed to 1,300 doctors in Liaoning Province, China. A total of 1,011 effective respondents became our final study subjects. Hierarchical linear regression analyses were performed by using SPSS 17.0 to explore the mediating role of PsyCap in the relation between work-family conflict and burnout. Both work interfering family conflict (WIF) and family interfering work conflict (FIW) were positively related with emotional exhaustion and cynicism among both male and females doctors. However, WIF was positively related with professional efficacy only among male doctors, whereas FIW was negatively related with professional efficacy among both male and female doctors. PsyCap partially mediated the relation between WIF and professional efficacy among male doctors and partially mediated the relations of FIW with emotional exhaustion, cynicism and professional efficacy among female doctors. Work-family conflict was associated with burnout among Chinese doctors. PsyCap was a mediator between work-family conflict and burnout. PsyCap might be a positive resource to reduce the negative effect of work-family conflict on burnout of doctors, especially female doctors, in China.

  20. Creativity in Court-Connected Mediation: Myth or Reality?

    Adrian, Lin; Mykland, Solfrid

    2014-01-01

    In this study, we examined creativity in court-connected mediation. We analyzed 129 mediated agreements from civil cases in Norway and Denmark and compared the outcomes with the parties' original claims to determine whether the agreement addressed only the disputants' demands or contained other...... elements. If the mediated agreements contained elements in addition to the original claims, we considered them to be “creative.” We devised a creativity scale and found that approximately two thirds of the cases contained creative elements and one quarter of them contained more than five creative elements....... We then sought to determine which aspects of the mediation promoted creativity by looking at a variety of mediation characteristics (length of mediation, characteristics of the parties, etc.). We found that lengthier mediations tended to feature more creativity as did cases that involved two private...

  1. Depression as a mediator between family factors and peer-bullying victimization in Latino adolescents.

    Yabko, Brandon A; Hokoda, Audrey; Ulloa, Emilio C

    2008-01-01

    The purpose of this study was to assess the mediating role of depression in three different relationships: (a) sibling bullying and peer victimization, (b) mothers' power-assertive parenting and peer victimization, and (c) fathers' power-assertive parenting and peer victimization. Results from 242 Latino middle school adolescents from a large southwestern city bordering Mexico revealed that both boys' and girls' peer victimization were related to familial factors and depression. Regression analyses for boys revealed that depression mediated three relationships: (a) sibling bullying and peer victimization, (b) mothers' power-assertive parenting and peer victimization, and (c) fathers' power-assertive parenting and peer victimization. Depression also mediated the relationship between fathers' power-assertive parenting and girls' victimization by peers. The findings support the development of family-based interventions for peer victimization that include curriculum addressing depression.

We find superpartner spectra that are markedly different from those of typical gauge and gaugino mediation scenarios. While typical gauge mediation predictions of either a neutralino or stau next-to-lightest supersymmetric particle (NLSP) are easily reproducible with the GGM parameters, chargino and sneutrino NLSPs are generic for many reasonable choices of GGM parameters.

    Ogibin, Yurii N; Elinson, Michail N; Nikishin, Gennady I

    2009-01-01

    The data on the use of mediator oxidation systems activated by electric current (anodic or parallel anodic and cathodic) in organic electrosynthesis are considered and generalised. Electrochemical activation of these systems permits successful application of catalytic versions and easy scaling of mediator-promoted processes. Chemical and environmental advantages of electrochemical processes catalysed by mediator oxidation systems are demonstrated. Examples of the application of organic and inorganic mediators for the oxidation of various classes of organic compounds under conditions of electrolysis are given.

  8. Introduction: Mediating and Remediating Death

    Christensen, Dorthe Refslund; Sandvik, Kjetil

    2014-01-01

    In this second volume we explore how people, groups and institutions deal with death through processes of mediation (the presentation of something through media), remediation (the representation of one medium in another, see below) and mediatization (the process through which core elements...... of a social or cultural activity assume media form, see below). The volume presents a wide variety of ethnographies of death from Norway, Finland, Sweden, the US, Papua New Guinea, Bosnia and Hercegovina, Libya, Tibet, Uganda and Denmark as well as a number of online sites and social media material....... These are analyzed through a vast number of theoretical and analytical perspectives in order to investigate how very diverse practices surrounding death and dying - mourning and commemoration, ritualization, politicization, re-enactment, traditionalization, activism or documentarism: private or public, offline...

  9. Mediatization: a concept, multiple voices

    Pedro Gilberto GOMES

    2016-12-01

    Full Text Available Mediatization has become increasingly a key concept, fundamental, essential to describe the present and the history of media and communicative change taking place. Thus, it became part of a whole, one can not see them as a separate sphere. In this perspective, the media coverage is used as a concept to describe the process of expansion of the different technical means and consider the interrelationships between the communicative change, means and sociocultural change. However, although many researchers use the concept of mediatization, each gives you the meaning that best suits your needs. Thus, the concept of media coverage is treated with multiple voices. This paper discusses this problem and present a preliminary pre-position on the matter.

  19. Axino dark matter in mirage mediation

    Nakamura, Shuntaro; Okumura, Ken-ichi; Yamaguchi, Masahiro

    2009-01-01

    The mirage mediation of supersymmetry breaking is a phenomenologically quite interesting possibility, however, it suffers from two major problems: the moduli-induced gravitino problem and the μ-Bμ problem. In this paper, we propose that the axionic extension of mirage mediation, axionic mirage mediation can solve both problems simultaneously. We address the cosmological consequences of the scenario extensively.

  20. Direct mediation, duality and unification

    Abel, Steven; Khoze, Valentin V.

    2008-01-01

    It is well-known that in scenarios with direct gauge mediation of supersymmetry breaking the messenger fields significantly affect the running of Standard Model couplings and introduce Landau poles which are difficult to avoid. Among other things, this appears to remove any possibility of a meaningful unification prediction and is often viewed as a strong argument against direct mediation. We propose two ways that Seiberg duality can circumvent this problem. In the first, which we call 'deflected-unification', the SUSY-breaking hidden sector is a magnetic theory which undergoes a Seiberg duality to an electric phase. Importantly, the electric version has fewer fundamental degrees of freedom coupled to the MSSM compared to the magnetic formulation. This changes the β-functions of the MSSM gauge couplings so as to push their Landau poles above the unification scale. We show that this scenario is realised for recently suggested models of gauge mediation based on a metastable SCQD-type hidden sector directly coupled to MSSM. The second possibility for avoiding Landau poles, which we call 'dual-unification', begins with the observation that, if the mediating fields fall into complete SU(5) multiplets, then the MSSM+messengers exhibits a fake unification at unphysical values of the gauge couplings. We show that, in known examples of electric/magnetic duals, such a fake unification in the magnetic theory reflects a real unification in the electric theory. We therefore propose that the Standard Model could itself be a magnetic dual of some unknown electric theory in which the true unification takes place. This scenario maintains the unification prediction (and unification scale) even in the presence of Landau poles in the magnetic theory below the GUT scale. We further note that this dual realization of grand unification can explain why Nature appears to unify, but the proton does not decay.

  1. Minimal ancilla mediated quantum computation

    Proctor, Timothy J.; Kendon, Viv

    2014-01-01

    Schemes of universal quantum computation in which the interactions between the computational elements, in a computational register, are mediated by some ancillary system are of interest due to their relevance to the physical implementation of a quantum computer. Furthermore, reducing the level of control required over both the ancillary and register systems has the potential to simplify any experimental implementation. In this paper we consider how to minimise the control needed to implement universal quantum computation in an ancilla-mediated fashion. Considering computational schemes which require no measurements and hence evolve by unitary dynamics for the global system, we show that when employing an ancilla qubit there are certain fixed-time ancilla-register interactions which, along with ancilla initialisation in the computational basis, are universal for quantum computation with no additional control of either the ancilla or the register. We develop two distinct models based on locally inequivalent interactions and we then discuss the relationship between these unitary models and the measurement-based ancilla-mediated models known as ancilla-driven quantum computation.

  2. Male-mediated developmental toxicity

    Diana Anderson

    2014-02-01

    Full Text Available Male-mediated developmental toxicity has been of concern for many years. The public became aware of male-mediated developmental toxicity in the early 1990s when it was reported that men working at Sellafield might be causing leukemia in their children. Human and animal studies have contributed to our current understanding of male-mediated effects. Animal studies in the 1980s and 1990s suggested that genetic damage after radiation and chemical exposure might be transmitted to offspring. With the increasing understanding that there is histone retention and modification, protamine incorporation into the chromatin and DNA methylation in mature sperm and that spermatozoal RNA transcripts can play important roles in the epigenetic state of sperm, heritable studies began to be viewed differently. Recent reports using molecular approaches have demonstrated that DNA damage can be transmitted to babies from smoking fathers, and expanded simple tandem repeats minisatellite mutations were found in the germline of fathers who were exposed to radiation from the Chernobyl nuclear power plant disaster. In epidemiological studies, it is possible to clarify whether damage is transmitted to the sons after exposure of the fathers. Paternally transmitted damage to the offspring is now recognized as a complex issue with genetic as well as epigenetic components.

  3. Substrate mediated enzyme prodrug therapy.

    Betina Fejerskov

    Full Text Available In this report, we detail Substrate Mediated Enzyme Prodrug Therapy (SMEPT as a novel approach in drug delivery which relies on enzyme-functionalized cell culture substrates to achieve a localized conversion of benign prodrug(s into active therapeutics with subsequent delivery to adhering cells or adjacent tissues. For proof-of-concept SMEPT, we use surface adhered micro-structured physical hydrogels based on poly(vinyl alcohol, β-glucuronidase enzyme and glucuronide prodrugs. We demonstrate enzymatic activity mediated by the assembled hydrogel samples and illustrate arms of control over rate of release of model fluorescent cargo. SMEPT was not impaired by adhering cells and afforded facile time - and dose - dependent uptake of the in situ generated fluorescent cargo by hepatic cells, HepG2. With the use of a glucuronide derivative of an anticancer drug, SN-38, SMEPT afforded a decrease in cell viability to a level similar to that achieved using parent drug. Finally, dose response was achieved using SMEPT and administration of judiciously chosen concentration of SN-38 glucuronide prodrug thus revealing external control over drug delivery using drug eluting surface. We believe that this highly adaptable concept will find use in diverse biomedical applications, specifically surface mediated drug delivery and tissue engineering.

  4. Effectiveness of Parent-Child Mediation in Improving Family Functioning and Reducing Adolescent Problem Behavior: Results from a Pilot Randomized Controlled Trial.

    Tucker, Joan S; Edelen, Maria Orlando; Huang, Wenjing

    2017-03-01

    Parent-child mediation programs are intended to resolve or manage disputes and improve family functioning, but rigorous evaluations of their effectiveness are lacking. Families referred to a community-based mediation program (N = 111) were randomized to an intervention or wait-list control group, and completed three surveys over a 12-week period. With the exception of parent-reported child delinquency (which decreased more in the intervention group), this evaluation provides little support for the short-term effectiveness of parent-child mediation for improving family functioning and reducing child problem behaviors in general. Given that this is the first randomized controlled trial of a parent-child mediation program, additional evaluations involving larger samples and longer follow-ups are needed before firm conclusions can be drawn about the effectiveness of this intervention.

  6. Maternal Emotion Regulation and Adolescent Behaviors: The Mediating Role of Family Functioning and Parenting.

    Crandall, AliceAnn; Ghazarian, Sharon R; Day, Randal D; Riley, Anne W

    2016-11-01

    Prior research links poor maternal emotion regulation to maladaptive parenting and child behaviors, but little research is available on these relationships during the adolescent period. We use structural equation modeling to assess the influence of poor maternal emotion regulation, measured as emotional reactivity and distancing, on adolescent behaviors (measured as aggression and prosocial behaviors) among 478 adolescents (53 % female; baseline age 10-13 years) and their mothers over a 5 year period. We also tested the possible mediating roles of family functioning and parenting behaviors between maternal emotion regulation and adolescent behaviors. Results indicated that higher baseline maternal emotional distancing and reactivity were not directly predictive of adolescents' behaviors, but they were indirectly related through family functioning and parenting. Specifically, indulgent parenting mediated the relationship between maternal emotional reactivity and adolescent aggression. Maternal-reported family functioning significantly mediated the relationship between maternal emotional distancing and adolescent aggression. Family functioning also mediated the relationship between emotional distancing and regulation parenting. The results imply that poor maternal emotion regulation during their child's early adolescence leads to more maladaptive parenting and problematic behaviors during the later adolescent period. However, healthy family processes may ameliorate the negative impact of low maternal emotion regulation on parenting and adolescent behavioral outcomes. The implications for future research and interventions to improve parenting and adolescent outcomes are discussed.

  7. The mediation police in family and couple conflict: analysis of the agreements

    Diego Becerril

    2017-01-01

    Full Text Available Mediation is an alternative, increasingly implemented, for the resolution of conflicts outside the judicial sphere and one of its applications in conflicts reported to the police. The present work is part of an experience of police mediation that has been carried out during the years 2012-2014. Two data collection techniques have been applied: on the one hand, in the analysis of the files, with the whole set of variables that may be applicable; And by performing questionnaires to the parties involved. The two conditions adopted as a criterion in the selection of cases that refer to family conflicts of partners and which were registered in a resolution agreement. With these data, the analysis affects, beyond the characteristics, in the satisfaction of the process and the permanence of the conflict. As conclusions, the incidence of sociodemographic variables, especially the level of studies and occupational and the high degree of satisfaction and recommendation of the service, stands out. However, there is a high rate of repetition of conflicts, especially in cases of family conflicts.

    Olsen, Thomas; Schiøtz, Jakob

    2009-01-01

    A wide range of experiments have established that certain chemical reactions at metal surfaces can be driven by multiple hot-electron-mediated excitations of adsorbates. A high transient density of hot electrons is obtained by means of femtosecond laser pulses and a characteristic feature of such...... density functional theory and the delta self-consistent field method. With a simplifying assumption, the power law becomes exact and we obtain a simple physical interpretation of the exponent n, which represents the number of adsorbate vibrational states participating in the reaction....

  15. Self-construal, mental distress, and family relations: a mediated moderation analysis with Asian American adolescents.

    Liu, Freda F; Goto, Sharon G

    2007-04-01

    The interactive effects between interdependent and independent self-construal on family cohesion and mental distress were examined. Survey responses from 153 Asian American high school students supported the hypothesized moderation of interdependence by independence on family cohesion, which was found to further mediate the relationship between self-construal and mental distress. Specifically, interdependence was positively associated with family cohesion when independence was high and negatively associated with family cohesion when independence was low. Accounting for the mediator effects of family cohesion, mental distress was positively associated with interdependence and more so for those low on independence than those high on independence. The benefits of biculturalism and research implications for the bidimensional conceptualization of self-construal for ethnic minority populations are discussed. (c) 2007 APA, all rights reserved.

  16. Mandatory presuit mediation: 5-year results of a medical malpractice resolution program.

    Jenkins, Randall C; Smillov, Arlene E; Goodwin, Matthew A

    2014-01-01

    The Florida Patient Safety and Presuit Mediation Program (FLPSMP) is a mandatory mediation program designed to provide deserving patients with fast, fair compensation while limiting the healthcare provider expenses incurred during traditional litigation. Mediation occurs before litigation begins; therefore, patients with meritorious claims receive compensation often years earlier than they would with extended litigation. This early mediation fosters confidential and candid communication between doctors and patients, which promotes early fact-finding and candid discussion. The program went into effect across the University of Florida (UF) Health system on January 1, 2008. In an article previously published in this journal, we discussed the positive trend observed 2 years after the implementation of the FLPSMP. This article incorporates 5 years of data, which includes new benchmarks with state and national data, to demonstrate that the program can be used successfully as a medical malpractice solution. © 2014 American Society for Healthcare Risk Management of the American Hospital Association.

  17. Contentious Conversations: Using Mediation Techniques in Difficult Clinical Ethics Consultations.

    Fiester, Autumn

    2015-01-01

    Mediators utilize a wide range of skills in the process of facilitating dialogue and resolving conflicts. Among the most useful techniques for clinical ethics consultants (CECs)-and surely the least discussed-are those employed in acrimonious, hostile conversations between stakeholders. In the context of clinical ethics disputes or other bedside conflicts, good mediation skills can reverse the negative interactions that have prevented the creation of workable treatment plans or ethical consensus. This essay lays out the central framework mediators use in distinguishing positions from interests and describes a set of strategies for managing contentious ethics consultations or working with "difficult" patients, families, or patient-careprovider interactions.

  18. Immunoglobulin E-Mediated Autoimmunity

    Marcus Maurer

    2018-04-01

    Full Text Available The study of autoimmunity mediated by immunoglobulin E (IgE autoantibodies, which may be termed autoallergy, is in its infancy. It is now recognized that systemic lupus erythematosus, bullous pemphigoid (BP, and chronic urticaria, both spontaneous and inducible, are most likely to be mediated, at least in part, by IgE autoantibodies. The situation in other conditions, such as autoimmune uveitis, rheumatoid arthritis, hyperthyroid Graves’ disease, autoimmune pancreatitis, and even asthma, is far less clear but evidence for autoallergy is accumulating. To be certain of an autoallergic mechanism, it is necessary to identify both IgE autoantibodies and their targets as has been done with the transmembrane protein BP180 and the intracellular protein BP230 in BP and IL-24 in chronic spontaneous urticaria. Also, IgE-targeted therapies, such as anti-IgE, must have been shown to be of benefit to patients as has been done with both of these conditions. This comprehensive review of the literature on IgE-mediated autoallergy focuses on three related questions. What do we know about the prevalence of IgE autoantibodies and their targets in different diseases? What do we know about the relevance of IgE autoantibodies in different diseases? What do we know about the cellular and molecular effects of IgE autoantibodies? In addition to providing answers to these questions, based on a broad review of the literature, we outline the current gaps of knowledge in our understanding of IgE autoantibodies and describe approaches to address them.

  19. Hydrological models are mediating models

    Babel, L. V.; Karssenberg, D.

    2013-08-01

    Despite the increasing role of models in hydrological research and decision-making processes, only few accounts of the nature and function of models exist in hydrology. Earlier considerations have traditionally been conducted while making a clear distinction between physically-based and conceptual models. A new philosophical account, primarily based on the fields of physics and economics, transcends classes of models and scientific disciplines by considering models as "mediators" between theory and observations. The core of this approach lies in identifying models as (1) being only partially dependent on theory and observations, (2) integrating non-deductive elements in their construction, and (3) carrying the role of instruments of scientific enquiry about both theory and the world. The applicability of this approach to hydrology is evaluated in the present article. Three widely used hydrological models, each showing a different degree of apparent physicality, are confronted to the main characteristics of the "mediating models" concept. We argue that irrespective of their kind, hydrological models depend on both theory and observations, rather than merely on one of these two domains. Their construction is additionally involving a large number of miscellaneous, external ingredients, such as past experiences, model objectives, knowledge and preferences of the modeller, as well as hardware and software resources. We show that hydrological models convey the role of instruments in scientific practice by mediating between theory and the world. It results from these considerations that the traditional distinction between physically-based and conceptual models is necessarily too simplistic and refers at best to the stage at which theory and observations are steering model construction. The large variety of ingredients involved in model construction would deserve closer attention, for being rarely explicitly presented in peer-reviewed literature. We believe that devoting

  20. Mediated electrochemical hazardous waste destruction

    Hickman, R.G.; Farmer, J.C.; Wang, F.T.

    1992-03-01

    There are few permitted processes for mixed waste (radioactive plus chemically hazardous) treatment. We are developing an electrochemical process, based upon mediated electrochemical oxidation (MEO), that converts toxic organic components of mixed waste to water, carbon dioxide, and chloride or chloride precipitates. Aggressive oxidizer ions such as Ag 2+ , Co 3+ , or Fe 3+ are produced at an anode. These can attack organic molecules directly, and may also produce hydroxyl free radicals that promote destruction. Solid and liquid radioactive waste streams containing only inorganic radionuclide forms may be treated with existing technology and prepared for final disposal. The coulombic efficiency of the process has been determined, as well as the destruction efficiency for ethylene glycol, a surrogate waste. In addition, hazardous organic materials are becoming very expensive to dispose of and when they are combined with transuranic radioactive elements no processes are presently permitted. Mediated electrochemical oxidation is an ambient- temperature aqueous-phase process that can be used to oxidize organic components of mixed wastes. Problems associated with incineration, such as high-temperature volatilization of radionuclides, are avoided. Historically, Ag(II) has been used as a mediator in this process. Fe(III) and Co(III) are attractive alternatives to Ag(II) since they form soluble chlorides during the destruction of chlorinated solvents. Furthermore, silver itself is toxic heavy metal. Quantitative data have been obtained for the complete oxidation of ethylene glycol by Fe(III) and Co(III). Though ethylene glycol is a nonhalogenated organic, these data have enabled us to make direct comparisons of activities of Fe(III) and Co(III) with Ag(II). Very good quantitative data for the oxidation of ethylene glycol by Ag(II) had already been collected

  1. Prospective relations between family conflict and adolescent maladjustment: security in the family system as a mediating process.

    Cummings, E Mark; Koss, Kalsea J; Davies, Patrick T

    2015-04-01

    Conflict in specific family systems (e.g., interparental, parent-child) has been implicated in the development of a host of adjustment problems in adolescence, but little is known about the impact of family conflict involving multiple family systems. Furthermore, questions remain about the effects of family conflict on symptoms of specific disorders and adjustment problems and the processes mediating these effects. The present study prospectively examines the impact of family conflict and emotional security about the family system on adolescent symptoms of specific disorders and adjustment problems, including the development of symptoms of anxiety, depression, conduct problems, and peer problems. Security in the family system was examined as a mediator of these relations. Participants included 295 mother-father-adolescent families (149 girls) participating across three annual time points (grades 7-9). Including auto-regressive controls for initial levels of emotional insecurity and multiple adjustment problems (T1), higher-order emotional insecurity about the family system (T2) mediated relations between T1 family conflict and T3 peer problems, anxiety, and depressive symptoms. Further analyses supported specific patterns of emotional security/insecurity (i.e., security, disengagement, preoccupation) as mediators between family conflict and specific domains of adolescent adjustment. Family conflict was thus found to prospectively predict the development of symptoms of multiple specific adjustment problems, including symptoms of depression, anxiety, conduct problems, and peer problems, by elevating in in adolescent's emotional insecurity about the family system. The clinical implications of these findings are considered.

    We consider a gaugino-mediated supersymmetry breaking scenario where in addition to the gauginos the Higgs fields couple directly to the field that breaks supersymmetry. This yields non-vanishing trilinear scalar couplings in general, which can lead to large mixing in the stop sector providing a sufficiently large Higgs mass. Using the most recent release of FeynHiggs, we show the implications on the parameter space. Assuming a gravitino LSP, we find allowed points with a neutralino, sneutrino or stau NLSP. We test these points against the results of Run 1 of the LHC, considering in particular searches for heavy stable charged particles.

    Korff, Lynn Von; Grotevant, Harold D.

    2012-01-01

    The present study examined adoption-related family conversation as a mediator of the association between adoptive parents’ facilitation of contact with birth relatives and adolescent adoptive identity formation. The sample consisted of 184 adoptive families. Data were collected in two waves from adoptive mothers and fathers, and adoptees (M = 15.68 years at adolescence; M = 24.95 years at emerging adulthood) using semistructured interviews and questionnaires. Structural equation models showed a good fit to sample data, and analyses supported the hypothesized mediation model. Contact with birth relatives is associated with more frequent adoption-related family conversation, which in turn is associated with the development of adoptive identity. These results highlight the importance of supporting activities such as contact that lead to adoption-related family conversation. PMID:21517175

    Research consistently documents the negative effects of work-family conflict; however, little research focuses on alcohol use. This study embraces a tension reduction theory of drinking, wherein alcohol use is thought to reduce the negative effects of stress. The purpose of the study was to test a moderated mediation model of the relationship between work-family conflict and alcohol use in a Chicagoland community sample of 998 caregivers. Structural equation models showed that distress mediated the relationship between work-family conflict and alcohol use. Furthermore, tension reduction expectancies of alcohol exacerbated the relationship between distress and alcohol use. The results advance the study of work-family conflict and alcohol use, helping explain this complicated relationship using sophisticated statistical techniques. Implications for theory and practice are discussed.

  7. Child/Adolescent's ADHD and Parenting Stress: The Mediating Role of Family Impact and Conduct Problems.

    Muñoz-Silva, Alicia; Lago-Urbano, Rocio; Sanchez-Garcia, Manuel; Carmona-Márquez, José

    2017-01-01

    Objective: The demands of parenting are usually associated with some stress, and elevated levels of stress may affect the parent-child relationships and parenting practices. This is especially the case of families where children have special needs conditions or disorders, like Attention Deficit Hyperactivity Disorder (ADHD). Method: This study examined parenting stress among mothers of children and adolescents with ADHD. The sample comprised 126 mothers of girls (36; 29%) and boys (90; 71%) aged 6-17 years old. Results: Mothers reported their own stress levels as well as the children and adolescents' variables (severity of their ADHD symptoms, conduct, and emotional problems) and family-contextual variables (negative impact on family's social life, impact on couple relationship, and perceived social support). Hierarchical multiple regression showed that (a) negative impact on social life and conduct problems were the strongest predictors of mother's stress. Bootstrap mediation analyses revealed that (b) the association between child and adolescent's ADHD and parenting stress was mediated by children's conduct problems and by negative impact on family's social life, and not by children's emotional problems nor by mother's perceived social support. The mediation analysis also suggested (c) a pathway from child/adolescent's ADHD through children's conduct problems and then through their negative impact on family's social life to mother's parenting stress. Conclusion: These results suggest that both child/adolescent's and family factors should be considered in the designing of interventions for reducing parenting stress in families of children and adolescents with ADHD.

    2013-12-01

    Full Text Available This paper presents considerations about Initial Petition, textual/discursive genre, which is a genre circumscribed in the judicial domain with relation to the Commitment. For this purpose, this article exposes the text plan of the Initial Petition from the postulations of Adam (2011. In the same way, it studies the mediative frameworks based on Guentchéva (1994, 1996, which develop the notion of mediative grammatical categories, that permits the linguistic marking of distance and engagement of the enunciator with regard to the information expressed. It evidences the relevance of the use of mediated constructions in the judicial text, as they function as attenuated strategies to the responsibility of the producer of the text with what is said, and at the same time points to a discourse of authority through the entrance of the sources of law.

  10. Mediation designs for tobacco prevention research

    MacKinnon, David P.; Taborga, Marcia P.; Morgan-Lopez, Antonio A.

    2010-01-01

    This paper describes research designs and statistical analyses to investigate how tobacco prevention programs achieve their effects on tobacco use. A theoretical approach to program development and evaluation useful for any prevention program guides the analysis. The theoretical approach focuses on action theory for how the program affects mediating variables and on conceptual theory for how mediating variables are related to tobacco use. Information on the mediating mechanisms by which tobacco prevention programs achieve effects is useful for the development of efficient programs and provides a test of the theoretical basis of prevention efforts. Examples of these potential mediating mechanisms are described including mediated effects through attitudes, social norms, beliefs about positive consequences, and accessibility to tobacco. Prior research provides evidence that changes in social norms are a critical mediating mechanism for successful tobacco prevention. Analysis of mediating variables in single group designs with multiple mediators are described as well as multiple group randomized designs which are the most likely to accurately uncover important mediating mechanisms. More complicated dismantling and constructive designs are described and illustrated based on current findings from tobacco research. Mediation analysis for categorical outcomes and more complicated statistical methods are outlined. PMID:12324176

  11. The Mediator complex and transcription regulation

    Poss, Zachary C.; Ebmeier, Christopher C.

    2013-01-01

    The Mediator complex is a multi-subunit assembly that appears to be required for regulating expression of most RNA polymerase II (pol II) transcripts, which include protein-coding and most non-coding RNA genes. Mediator and pol II function within the pre-initiation complex (PIC), which consists of Mediator, pol II, TFIIA, TFIIB, TFIID, TFIIE, TFIIF and TFIIH and is approximately 4.0 MDa in size. Mediator serves as a central scaffold within the PIC and helps regulate pol II activity in ways that remain poorly understood. Mediator is also generally targeted by sequence-specific, DNA-binding transcription factors (TFs) that work to control gene expression programs in response to developmental or environmental cues. At a basic level, Mediator functions by relaying signals from TFs directly to the pol II enzyme, thereby facilitating TF-dependent regulation of gene expression. Thus, Mediator is essential for converting biological inputs (communicated by TFs) to physiological responses (via changes in gene expression). In this review, we summarize an expansive body of research on the Mediator complex, with an emphasis on yeast and mammalian complexes. We focus on the basics that underlie Mediator function, such as its structure and subunit composition, and describe its broad regulatory influence on gene expression, ranging from chromatin architecture to transcription initiation and elongation, to mRNA processing. We also describe factors that influence Mediator structure and activity, including TFs, non-coding RNAs and the CDK8 module. PMID:24088064

  12. PPARγ and the Innate Immune System Mediate the Resolution of Inflammation

    Amanda Croasdell

    2015-01-01

    Full Text Available The resolution of inflammation is an active and dynamic process, mediated in large part by the innate immune system. Resolution represents not only an increase in anti-inflammatory actions, but also a paradigm shift in immune cell function to restore homeostasis. PPARγ, a ligand activated transcription factor, has long been studied for its anti-inflammatory actions, but an emerging body of literature is investigating the role of PPARγ and its ligands (including thiazolidinediones, prostaglandins, and oleanolic acids in all phases of resolution. PPARγ can shift production from pro- to anti-inflammatory mediators by neutrophils, platelets, and macrophages. PPARγ and its ligands further modulate platelet and neutrophil function, decreasing trafficking, promoting neutrophil apoptosis, and preventing platelet-leukocyte interactions. PPARγ alters macrophage trafficking, increases efferocytosis and phagocytosis, and promotes alternative M2 macrophage activation. There are also roles for this receptor in the adaptive immune response, particularly regarding B cells. These effects contribute towards the attenuation of multiple disease states, including COPD, colitis, Alzheimer’s disease, and obesity in animal models. Finally, novel specialized proresolving mediators—eicosanoids with critical roles in resolution—may act through PPARγ modulation to promote resolution, providing another exciting area of therapeutic potential for this receptor.

  13. Multifunctional Curcumin Mediate Multitherapeutic Effects.

    Shehzad, Adeeb; Qureshi, Munibah; Anwar, Muhammad Nabeel; Lee, Young Sup

    2017-09-01

    Inflammation can promote the development of arthritis, obesity, cardiovascular, type II diabetes, pancreatitis, metabolic and neurodegenerative diseases, and certain types of cancer. Compounds isolated from plants have been practiced since ancient times for curing various ailments including inflammatory disorders and to support normal physiological functions. Curcumin (diferuloylmethane) is a yellow coloring agent, extracted from turmeric that has been used for the prevention and treatment of various inflammatory diseases. Numerous studies have shown that curcumin modulate multiple molecular targets and can be translated to the clinics for multiple therapeutic processes. There is compelling evidence that curcumin can block cell proliferation, invasion, and angiogenesis as well as reduced the prolonged survival of cancer cells. Curcumin mediates anti-inflammatory effect through downregulation of inflammatory cytokines, transcription factors, protein kinases, and enzymes that promote inflammation and development of chronic diseases. In addition, curcumin induces apoptosis through mitochondrial and receptor-mediated pathways by activating caspase cascades. Curcumin is a safe and nontoxic drug that has been reported to be well tolerated. Available clinical trials support the potential role of curcumin for treatment of various inflammatory disorders. However, curcumin's efficacy is hindered by poor absorption and low bioavailability, which limit its translation into clinics. This review outlines the potential pharmacological and clinical role of curcumin, which provide a gateway for the beneficial role of plant isolated compounds in treatment of various inflammatory diseases and cancer. © 2017 Institute of Food Technologists®.

  14. Desperately Trying to Mediate Immediacy

    Andreas Oliver Schellewald

    2018-01-01

    Full Text Available Evermore aspects of contemporary cultures, societies and human life appear to be changed through processes of digitization and mediatization. A great body of work is touching on these processes of change. However, not many discuss aspects of leisure and aesthetics. And if they do so, seldom regarding bodily and worldly aspects. This paper thus seeks to discuss such changes alongside the phenomenon of esports. More precisely, the paper situates the aesthetic dimension and practices of watching and doing esports in contemporary cultures and societies, focusing on lived experiences (ästhetisches Erleben in digital and mediated contexts. The failing attempt to understand, the attempt to re-present and Gelassenheit (composure or serenity are introduced as modes of coping with immediate aesthetic experiences. Here, especially the constitutive transition from a physical to a meta-physical dimension of reality will be grasped on. By that, ongoing philosophical debates about the constitution of reality and being can be supported in their progress.

  15. Direct detection with dark mediators

    Curtin, David; Surujon, Ze' ev [C. N. Yang Institute for Theoretical Physics, Stony Brook University, Stony Brook, NY 11794 (United States); Tsai, Yuhsin [Physics Department, University of California Davis, Davis, CA 95616 (United States)

    2014-11-10

    We introduce dark mediator Dark Matter (dmDM) where the dark and visible sectors are connected by at least one light mediator ϕ carrying the same dark charge that stabilizes DM. ϕ is coupled to the Standard Model via an operator q{sup ¯}qϕϕ{sup ⁎}/Λ, and to dark matter via a Yukawa coupling y{sub χ}χ{sup c¯}χϕ. Direct detection is realized as the 2→3 process χN→χ{sup ¯}Nϕ at tree-level for m{sub ϕ}≲10 keV and small Yukawa coupling, or alternatively as a loop-induced 2→2 process χN→χN. We explore the direct-detection consequences of this scenario and find that a heavy O(100 GeV) dmDM candidate fakes different O(10 GeV) standard WIMPs in different experiments. Large portions of the dmDM parameter space are detectable above the irreducible neutrino background and not yet excluded by any bounds. Interestingly, for the m{sub ϕ} range leading to novel direct detection phenomenology, dmDM is also a form of Self-Interacting Dark Matter (SIDM), which resolves inconsistencies between dwarf galaxy observations and numerical simulations.

  16. Conditional Mediation of Absorptive Capacity and Environment in International Entrepreneurial Orientation of Family Businesses.

    Hernández-Perlines, Felipe; Xu, Wenkai

    2018-01-01

    This study analyzes the effect of conditional mediation of environment-absorptive capacity in international entrepreneurial orientation of family businesses. Results involve data from 218 Spanish family businesses, analyzed with SmartPLS 3.2.7 software. This paper presents a relevant contribution both to the academic field and the performance of family firms, helping to understand the process of transforming international entrepreneurial orientation into a better international performance through absorptive capacity while family businesses invest their efforts in aligning international entrepreneurial orientation and absorptive capacity with international results, bearing in mind the positive moderator effect of environment. The most relevant contribution of this work is to integrate in the same model the mediating effect of the absorption capacity and the moderating effect of the environment: the effect of the international entrepreneurial orientation on the international performance of family businesses improves with the mediation of the absorptive capacity (the variability of international performance goes from 32.5 to 40.6%) and the moderation of the environment (to variability of international performance goes from 40.6 to 45.3%).

    2015-01-01

    In the current study, we examined a moderated mediation model using the risk and resilience framework. Specifically, the impact of family material hardship on adolescent problem behaviors was examined in a Chinese sample; we used the family stress model framework to investigate parental depression and negative parenting as potential mediators of the relation between family material hardship and adolescents' problem behaviors. In addition, based on resilience theory, we investigated adolescents' resilience as a potential protective factor in the development of their internalizing and externalizing problems. Participants included 1,419 Chinese adolescents (mean age = 15.38 years, SD = 1.79) and their primary caregivers. After controlling for covariates (age, gender, location of family residence, and primary caregiver), we found that parental depression and negative parenting mediated the association between family material hardship and adolescents' problem behaviors. Furthermore, the adolescent resilience moderated the relationship between negative parenting and internalizing problems in a protective-stabilizing pattern; in addition, a protective-reactive pattern also emerged when adolescent resilience was examined as a moderator of the relationship between negative parenting and externalizing problems. These findings contribute to a comprehensive understanding of the mechanisms of risk and resilience in youth development. Moreover, the findings have important implications for the prevention of adolescent problem behaviors.

    Family-based treatment (FBT) for adolescent anorexia nervosa (AN) promotes faster weight restoration when compared to other treatments. However, the mechanisms through which this occurs are not clarified. This study explored the trajectories of parental self-efficacy and perceived family flexibility during FBT and systemic family therapy (SyFT). We also explored whether parental self-efficacy mediates the effects of treatment on weight gain early in treatment. 158 adolescents (12-18 years old; 89% girls) and their parents were randomized to FBT or SyFT. Parental self-efficacy as well as adolescents' and parental perceptions of the family's flexibility were collected at baseline and at sessions 2, 4, 6, and 8. Over time, only parents in FBT reported significantly greater self-efficacy. The change in maternal self-efficacy over the first 8 weeks of treatment was a significant mediator of session 10 weight gain. There were no significant group differences in perceived flexibility by session 8. Both parents in FBT and mothers in SyFT understand early the need to change their family's rules and roles. However, the specific strategies of FBT appear to mediate early weight gain in AN. © 2018 Wiley Periodicals, Inc.

  19. Mediators of Effects of a Selective Family-Focused Violence Prevention Approach for Middle School Students

    2013-01-01

    This study examined how parenting and family characteristics targeted in a selective prevention program mediated effects on key youth proximal outcomes related to violence perpetration. The selective intervention was evaluated within the context of a multi-site trial involving random assignment of 37 schools to four conditions: a universal intervention composed of a student social-cognitive curriculum and teacher training, a selective family-focused intervention with a subset of high-risk students, a condition combining these two interventions, and a no-intervention control condition. Two cohorts of sixth-grade students (total N=1,062) exhibiting high levels of aggression and social influence were the sample for this study. Analyses of pre-post change compared to controls using intent-to-treat analyses found no significant effects. However, estimates incorporating participation of those assigned to the intervention and predicted participation among those not assigned revealed significant positive effects on student aggression, use of aggressive strategies for conflict management, and parental estimation of student’s valuing of achievement. Findings also indicated intervention effects on two targeted family processes: discipline practices and family cohesion. Mediation analyses found evidence that change in these processes mediated effects on some outcomes, notably aggressive behavior and valuing of school achievement. Results support the notion that changing parenting practices and the quality of family relationships can prevent the escalation in aggression and maintain positive school engagement for high-risk youth.

  2. U(1) mediation of flux supersymmetry breaking

    Grimm, Thomas W.; Klemm, Albrecht

    2008-10-01

    We study the mediation of supersymmetry breaking triggered by background fluxes in Type II string compactifications with Script N = 1 supersymmetry. The mediation arises due to an U(1) vector multiplet coupling to both a hidden supersymmetry breaking flux sector and a visible D-brane sector. The required internal manifolds can be constructed by non-Kähler resolutions of singular Calabi-Yau manifolds. The effective action encoding the U(1) coupling is then determined in terms of the global topological properties of the internal space. We investigate suitable local geometries for the hidden and visible sector in detail. This includes a systematic study of orientifold symmetries of del Pezzo surfaces realized in compact geometries after geometric transition. We construct compact examples admitting the key properties to realize flux supersymmetry breaking and U(1) mediation. Their toric realization allows us to analyze the geometry of curve classes and confirm the topological connection between the hidden and visible sector.

    Hess and Camara (1979) have shown that it is post-divorce family functioning, rather than family structure, that is most important in influencing the effects of divorce on children. A child's adjustment to divorce should be viewed as a developmental process rather than as a single event. Consequently, it is important to focus on the ways in which…

  6. Court-Annexed Mediation Practice in Malaysia: What the Future Holds

    Choong Yeow Choy

    2017-03-01

    Full Text Available It is an indubitable fact that the use of mediation as a form of dispute resolution process has gained traction across the globe. More importantly, the practice of mediation has also been transformed through the establishment of several techniques for formalised mediation. This article will provide insights into one of these avenues for formalised mediation, namely, court-annexed mediation practice in Malaysia. It will first discuss the motivations that led to the introduction of such a programme. This will be followed by an analysis of the operational aspects of the practice. A matter of utmost importance concerns the role of the courts and the judiciary in court-annexed mediation and this aspect is considered in considerable detail. This article will then offer suggestions on how some of the challenges that exist and are inherent in this particular method of formalised mediation could be overcome. These views are expressed with the hope that court-annexed mediation can function as an effective alternative dispute resolution mechanism under the umbrella of the Malaysian courts. Last but not least, it is also hoped that the above deliberations will be a catalyst for further comparative research and debates concerning this increasingly imperative form of formalised mediation process across all jurisdictions.

  7. Robust Mediation Analysis Based on Median Regression

    Yuan, Ying; MacKinnon, David P.

    2014-01-01

    Mediation analysis has many applications in psychology and the social sciences. The most prevalent methods typically assume that the error distribution is normal and homoscedastic. However, this assumption may rarely be met in practice, which can affect the validity of the mediation analysis. To address this problem, we propose robust mediation analysis based on median regression. Our approach is robust to various departures from the assumption of homoscedasticity and normality, including heavy-tailed, skewed, contaminated, and heteroscedastic distributions. Simulation studies show that under these circumstances, the proposed method is more efficient and powerful than standard mediation analysis. We further extend the proposed robust method to multilevel mediation analysis, and demonstrate through simulation studies that the new approach outperforms the standard multilevel mediation analysis. We illustrate the proposed method using data from a program designed to increase reemployment and enhance mental health of job seekers. PMID:24079925

  8. Regulation of metabolism by the Mediator complex.

    Youn, Dou Yeon; Xiaoli, Alus M; Pessin, Jeffrey E; Yang, Fajun

    2016-01-01

    The Mediator complex was originally discovered in yeast, but it is conserved in all eukaryotes. Its best-known function is to regulate RNA polymerase II-dependent gene transcription. Although the mechanisms by which the Mediator complex regulates transcription are often complicated by the context-dependent regulation, this transcription cofactor complex plays a pivotal role in numerous biological pathways. Biochemical, molecular, and physiological studies using cancer cell lines or model organisms have established the current paradigm of the Mediator functions. However, the physiological roles of the mammalian Mediator complex remain poorly defined, but have attracted a great interest in recent years. In this short review, we will summarize some of the reported functions of selective Mediator subunits in the regulation of metabolism. These intriguing findings suggest that the Mediator complex may be an important player in nutrient sensing and energy balance in mammals.

    The aim of this study was to explore caregiving self-efficacy as a mediator for the association between family functioning and caregiving appraisal of dementia family caregivers in Taiwan. This study adopted a cross-sectional correlational design. Purposive sampling was used to recruit 115 dyads of dementia patients and family caregivers from the outpatient neurological clinics of two hospitals in northern Taiwan. Data were gathered through interviews with a structured questionnaire, which included demographic characteristics for caregivers and patients, family functioning, caregiving self-efficacy, as well as positive and negative aspects of caregiving appraisal. Family functioning, patients' activities of daily living score, Neuropsychiatric Inventory caregiver distress, and three domains of self-efficacy were significantly associated with caregiver burden. Hierarchical multiple regression analyses indicated that self-efficacy for obtaining respite (SE-OR) significantly explained 20.5% of the variance in caregiver esteem. Caregiver perceived worsened health status, family functioning, and SE-OR significantly explained 59% of the variance in caregiver burden. The mediation test only supported the partially mediating role of SE-OR on the relationship between family functioning and caregiver burden, while the mediating effect of self-efficacy for responding to disruptive behaviours and controlling upsetting thoughts were insignificant. Our findings provided preliminary evidence for health professionals recommending that future studies should assess the family dynamic and health problems of caregivers, and develop appropriate family-centred interventions that focus on strengthening interfamily support and respite services to alleviate caregiver burden.

    2014-02-01

    Full Text Available Community mediation takes all forms and shapes all over the world. In order to better understand its limitations in adapting to different contexts, we have compared the evolution of community mediation services in two totally different systems, USA and Sri Lanka. Based on this analysis and the results of a research conducted in Cluj-Napoca in the fall of 2013, we have recommended a community mediation model suitable for the current Romanian social, economic and cultural framework.

    2014-01-01

    Parents use active and restrictive mediation strategies to guide and regulate children's online participation and the online risks they encounter. However, changes in parental mediation do occur over time and the effectiveness of these strategies on cyberbullying demands for further empirical investigation. The current study addresses these issues with a sample of 1084 students (49% girls) in a longitudinal, three-wave design. Gender differences were tested via multi-group analyses. Longitudinal growth models showed that parental use of both active and restrictive mediation decreased over time. For both types of mediation, the mean rate of change had a significant effect on boys' engagement in cyberbullying, but not for girls. Initial levels of restrictive mediation, but not active mediation, were found to be significantly predictive of cyberbullying in both genders. Girls had higher initial levels of both parental mediation types in comparison to boys. The results reveal that the effectiveness of active and restrictive mediation in relation to students' cyberbullying differs and informs us on gender differences. The implications of these results for parental education in online mediation are discussed.

  17. Transcription regulation by the Mediator complex.

    Soutourina, Julie

    2018-04-01

    Alterations in the regulation of gene expression are frequently associated with developmental diseases or cancer. Transcription activation is a key phenomenon in the regulation of gene expression. In all eukaryotes, mediator of RNA polymerase II transcription (Mediator), a large complex with modular organization, is generally required for transcription by RNA polymerase II, and it regulates various steps of this process. The main function of Mediator is to transduce signals from the transcription activators bound to enhancer regions to the transcription machinery, which is assembled at promoters as the preinitiation complex (PIC) to control transcription initiation. Recent functional studies of Mediator with the use of structural biology approaches and functional genomics have revealed new insights into Mediator activity and its regulation during transcription initiation, including how Mediator is recruited to transcription regulatory regions and how it interacts and cooperates with PIC components to assist in PIC assembly. Novel roles of Mediator in the control of gene expression have also been revealed by showing its connection to the nuclear pore and linking Mediator to the regulation of gene positioning in the nuclear space. Clear links between Mediator subunits and disease have also encouraged studies to explore targeting of this complex as a potential therapeutic approach in cancer and fungal infections.

    Full Text Available The essence of communication is to exchange and share information. Computers provide a new medium to human communication. CMC system, composed of human and computers, absorbs and then extends the advantages of all former formats of communication, embracing the instant interaction of oral communication, the abstract logics of printing dissemination, and the vivid images of movie and television. It also creates a series of new communication formats, such as Hyper Text, Multimedia etc. which are the information organizing methods, and cross-space message delivering patterns. Benefiting from the continuous development of technique and mechanism, the computer-mediated communication makes the dream of transmitting information cross space and time become true, which will definitely have a great impact on our social lives.

  1. Lepton-flavor violating mediators

    Galon, Iftah; Kwa, Anna [Department of Physics & Astronomy, University of California,Irvine, CA 92697 (United States); Tanedo, Philip [Department of Physics & Astronomy, University of California,Riverside, CA 92521 (United States)

    We present a framework where dark matter interacts with the Standard Model through a light, spin-0 mediator that couples chirally to pairs of different-flavor leptons. This flavor violating final state weakens bounds on new physics coupled to leptons from terrestrial experiments and cosmic-ray measurements. As an example, we apply this framework to construct a model for the Fermi-LAT excess of GeV γ-rays from the galactic center. We comment on the viability of this portal for self-interacting dark matter explanations of small scale structure anomalies and embeddings in flavor models. Models of this type are shown to be compatible with the muon anomalous magnetic moment anomaly. We review current experimental constraints and identify possible future theoretical and experimental directions.

  2. Phenomenological aspects of mirage mediation

    Loewen, Valeri

    2009-07-15

    We consider the possibility that string theory vacua with spontaneously broken supersymmetry and a small positive cosmological constant arise due to hidden sector matter interactions, known as F-uplifting/F-downlifting. We analyze this procedure in a model-independent way in the context of type IIB and heterotic string theory. Our investigation shows that the uplifting/downlifting sector has very important consequences for the resulting phenomenology. Not only does it adjust the vacuum energy, but it can also participate in the process of moduli stabilization. In addition, we find that this sector is the dominant source of supersymmetry breaking. It leads to a hybrid mediation scheme and its signature is a relaxed mirage pattern of the soft supersymmetry breaking terms. The low energy spectra exhibit distinct phenomenological properties and di er from conventional schemes considered so far. (orig.)

  4. Lepton-mediated electroweak baryogenesis

    Chung, Daniel J. H.; Garbrecht, Bjorn; Ramsey-Musolf, Michael J.; Tulin, Sean

    2010-01-01

    We investigate the impact of the tau and bottom Yukawa couplings on the transport dynamics for electroweak baryogenesis in supersymmetric extensions of the standard model. Although it has generally been assumed in the literature that all Yukawa interactions except those involving the top quark are negligible, we find that the tau and bottom Yukawa interaction rates are too fast to be neglected. We identify an illustrative 'lepton-mediated electroweak baryogenesis' scenario in which the baryon asymmetry is induced mainly through the presence of a left-handed leptonic charge. We derive analytic formulas for the computation of the baryon asymmetry that, in light of these effects, are qualitatively different from those in the established literature. In this scenario, for fixed CP-violating phases, the baryon asymmetry has opposite sign compared to that calculated using established formulas.

  5. Vasoactive mediators and splanchnic perfusion.

    Reilly, P M; Bulkley, G B

    1993-02-01

    To provide an overview of the splanchnic hemodynamic response to circulatory shock. Previous studies performed in our own laboratory, as well as a computer-assisted search of the English language literature (MEDLINE, 1966 to 1991), followed by a selective review of pertinent articles. Studies were selected that demonstrated relevance to the splanchnic hemodynamic response to circulatory shock, either by investigating the pathophysiology or documenting the sequelae. Article selection included clinical studies as well as studies in appropriate animal models. Pertinent data were abstracted from the cited articles. The splanchnic hemodynamic response to circulatory shock is characterized by a selective vasoconstriction of the mesenteric vasculature mediated largely by the renin-angiotensin axis. This vasospasm, while providing a natural selective advantage to the organism in mild-to-moderate shock (preserving relative perfusion of the heart, kidneys, and brain), may, in more severe shock, cause consequent loss of the gut epithelial barrier, or even hemorrhagic gastritis, ischemic colitis, or ischemic hepatitis. From a physiologic standpoint, nonpulsatile cardiopulmonary bypass, a controlled form of circulatory shock, has been found experimentally to significantly increase circulating levels of angiotensin II, the hormone responsible for this selective splanchnic vasoconstriction. While angiotensin II has been viewed primarily as the mediator responsible for the increased total vascular resistance seen during (and after) cardiopulmonary bypass, it may also cause the disproportionate decrease in mesenteric perfusion, as measured in human subjects by intraluminal gastric tonometry and galactose clearance by the liver, as well as the consequent development of the multiple organ failure syndrome seen in 1% to 5% of patients after cardiac surgery.

  6. Mediated electrochemical hazardous waste destruction

    Hickman, R.G.; Farmer, J.C.; Wang, F.T.

    1991-08-01

    There are few permitted processes for mixed waste (radioactive plus chemically hazardous) treatment. We are developing electrochemical processes that convert the toxic organic components of mixed waste to water, carbon dioxide, an innocuous anions such as chloride. Aggressive oxidizer ions such as Ag 2+ or Ce +4 are produced at an anode. These can attack the organic molecules directly. They can also attack water which yields hydroxyl free radicals that in turn attack the organic molecules. The condensed (i.e., solid and/or liquid) effluent streams contain the inorganic radionuclide forms. These may be treated with existing technology and prepared for final disposal. Kinetics and the extent of destruction of some toxic organics have been measured. Depending on how the process is operated, coulombic efficiency can be nearly 100%. In addition, hazardous organic materials are becoming very expensive to dispose of and when they are combined with transuranic radioactive elements no processes are presently permitted. Mediated electrochemical oxidation is an ambient-temperature aqueous-phase process that can be used to oxidize organic components of mixed wastes. Problems associated with incineration, such as high-temperature volatilization of radionuclides, are avoided. Historically, Ag (2) has been used as a mediator in this process. Fe(6) and Co(3) are attractive alternatives to Ag(2) since they form soluble chlorides during the destruction of chlorinated solvents. Furthermore, silver itself is a toxic heavy metal. Quantitative data has been obtained for the complete oxidation of ethylene glycol by Fe(6) and Co(3). Though ethylene glycol is a nonhalogenated organic, this data has enabled us to make direct comparisons of activities of Fe(6) and Co(3) with Ag(2). Very good quantitative data for the oxidation of ethylene glycol by Ag(2) had already been collected. 4 refs., 6 figs

    2016-01-01

    Depression is a major health concern for college students due to its substantial morbidity and mortality. Although low parental education has been identified as a factor in depression in college students, the mechanisms through which parental educational achievement affects students' depression are not well understood. We tested whether adverse family and college environments mediate the relationship between parental educational level and depression among Chinese college students. A total of 5180 respondents were selected using a cross-sectional survey. We examined the association of parental education, adverse family and college environments with depression in college students using the Adolescent Self-Rating Life Events Checklist, Beck Depression Inventory and socio-demographic questionnaires. Lower parental educational level is significantly correlated with depression in college students in our sample. Additionally, low family economic status, paternal or maternal unemployment, long periods spent apart from family, family conflicts, having been scolded and beaten by parents, poor or dissatisfying test performance, conflict with friends, heavy course load and failure in selection processes are also associated with parental education. Low family economic status, paternal or maternal unemployment, long periods spent apart from family, family conflicts, poor or dissatisfying test performance, conflict with friends and heavy course load mediated the relationship between parental education and depression in college students. Adverse family and college environments could explain the influence of parental educational level on depression in college students.

  11. Emotional intelligence and job performance: The mediating role of work-family balance.

    Weinzimmer, Laurence G; Baumann, Heidi M; Gullifor, Daniel P; Koubova, Veronika

    2017-01-01

    In this study, we examine the dynamics between emotional intelligence, work-family balance, and job performance. A review of the literature to date has shown distinct relationships between emotional intelligence to job performance and work-family balance to job performance. We utilize a sample of 233 respondents to empirically test our set of hypotheses that contend work-family balance mediates the relationship between emotional intelligence and job performance. Our results support these hypotheses. Practical implications and directions for future research are discussed.

  12. Family socioeconomic status, family health, and changes in students' math achievement across high school: A mediational model.

    Barr, Ashley Brooke

    2015-09-01

    In response to recent calls to integrate understandings of socioeconomic disparities in health with understandings of socioeconomic disparities in academic achievement, this study tested a mediational model whereby family socioeconomic status predicted gains in academic achievement across high school through its impact on both student and parent health. Data on over 8000 high school students in the U.S. were obtained from wave 1 (2009-2010) and wave 2 (2012) of the High School Longitudinal Study of 2009 (HSLS:09), and structural equation modeling with latent difference scores was used to determine the role of family health problems in mediating the well-established link between family SES and gains in academic achievement. Using both static and dynamic indicators of family SES, support was found for this mediational model. Higher family SES in 9th grade reduced the probability of students and their parents experiencing a serious health problem in high school, thereby promoting growth in academic achievement. In addition, parent and student health problems mediated the effect of changes in family SES across high school on math achievement gains. Results emphasize the importance of considering the dynamic nature of SES and that both student and parent health should be considered in understanding SES-related disparities in academic achievement. This relational process provides new mechanisms for understanding the intergenerational transmission of socioeconomic status and the status attainment process more broadly.

  13. Deeper Into Divorce: Using Actor–Partner Analyses to Explore Systemic Differences in Coparenting Conflict Following Custody Dispute Resolution

    Sbarra, David A.; Emery, Robert E.

    2010-01-01

    Divorce is an inherently interpersonal experience, yet too often adults’ reactions to marital dissolution are investigated as intrapersonal experiences that unfold outside of the relational context in which they exist. This article examines systemic patterns of interpersonal influence between divorced parents who were randomly assigned to either mediate or litigate a child custody dispute in the mid-1980s. Reports of coparenting conflict and nonacceptance of the divorce were assessed 5 weeks after the dispute settlement, 13 months after the settlement, and then again 12 years later. One hundred nine (N = 109) parents provided data over this 12-year period. Fathers reported the highest initial levels of conflict when their ex-partners were more accepting of the divorce. Mediation parents reported decreases in coparenting conflict in the year after dispute settlement, whereas litigation parents reported increases in conflict. Litigation parents evidenced the greatest long-term increases and decreases in coparenting conflict. Mediation is a potent force for reducing postdivorce conflict, and this article highlights the usefulness of adopting a systemic lens for understanding the long-term correlates of marital dissolution.

  14. Home environment as a predictor of child's language: A mediating role of family literacy activities and symbolic play

    Urška Fekonja-Peklaj

    2015-06-01

    Full Text Available In our study, we explored the ways in which SES-related factors of family environment affect child's language across toddlerhood and early childhood. We proposed a mediational path model in which we presumed that family literacy activities and parental encouragement of symbolic play acted as mediating variables, mediating the effect of parental education, family possessions and parent-to-child speech on child's language. The sample included 99 families with children, aged from 1 to 6 years. The data were collected in the family home, mostly via direct observation and by using a semi-structured interview with parents. The findings suggest that high-SES parents and parents who used a more complex and supportive speech, more frequently involved their children in different literacy activities. The effect of the parent-to-child speech on child's language proved to be mediated by parental use of mental transformations during symbolic play with a child.

  17. Supporting Family Carers Through Telephone-Mediated Group Programs: Opportunities For Gerontological Social Workers.

    Shanley, Chris

    2008-01-01

    Telephone-mediated group programs are an important but under-utilized medium for reaching frail or disabled older persons' family carers who are in need of support. The primary purpose and style of group programs can range across a broad spectrum–encompassing educational, supportive and therapeutic types. Gerontological social workers are the members of the multidisciplinary care team whose training, experience and supervision makes them most suitable for facilitating this broad range of group types. Drawing on the experience of training a number of group facilitators, this article provides suggestions for social workers contemplating the use of telephone-mediated groups and highlights groupwork skills peculiar to conducting group programs via the telephone.

    2011-01-01

    The Mediator complex transmits activation signals from DNA bound transcription factors to the core transcription machinery. Genome wide localization studies have demonstrated that Mediator occupancy not only correlates with high levels of transcription, but that the complex also is present at transcriptionally silenced locations. We provide evidence that Mediator localization is guided by an interaction with histone tails, and that this interaction is regulated by their post-translational modifications. A quantitative, high-density genetic interaction map revealed links between Mediator components and factors affecting chromatin structure, especially histone deacetylases. Peptide binding assays demonstrated that pure wild-type Mediator forms stable complexes with the tails of Histone H3 and H4. These binding assays also showed Mediator—histone H4 peptide interactions are specifically inhibited by acetylation of the histone H4 lysine 16, a residue critical in transcriptional silencing. Finally, these findings were validated by tiling array analysis that revealed a broad correlation between Mediator and nucleosome occupancy in vivo, but a negative correlation between Mediator and nucleosomes acetylated at histone H4 lysine 16. Our studies show that chromatin structure and the acetylation state of histones are intimately connected to Mediator localization. PMID:21742760

  5. Mediator: A key regulator of plant development.

    Buendía-Monreal, Manuel; Gillmor, C Stewart

    2016-11-01

    Mediator is a multiprotein complex that regulates transcription at the level of RNA pol II assembly, as well as through regulation of chromatin architecture, RNA processing and recruitment of epigenetic marks. Though its modular structure is conserved in eukaryotes, its subunit composition has diverged during evolution and varies in response to environmental and tissue-specific inputs, suggesting different functions for each subunit and/or Mediator conformation. In animals, Mediator has been implicated in the control of differentiation and morphogenesis through modulation of numerous signaling pathways. In plants, studies have revealed roles for Mediator in regulation of cell division, cell fate and organogenesis, as well as developmental timing and hormone responses. We begin this review with an overview of biochemical mechanisms of yeast and animal Mediator that are likely to be conserved in all eukaryotes, as well as a brief discussion of the role of Mediator in animal development. We then present a comprehensive review of studies of the role of Mediator in plant development. Finally, we point to important questions for future research on the role of Mediator as a master coordinator of development. Copyright © 2016 Elsevier Inc. All rights reserved.

  8. Mediator-dependent Nuclear Receptor Functions

    Chen, Wei; Roeder, Robert

    2011-01-01

    As gene-specific transcription factors, nuclear hormone receptors are broadly involved in many important biological processes. Their function on target genes requires the stepwise assembly of different coactivator complexes that facilitate chromatin remodeling and subsequent preinitiation complex (PIC) formation and function. Mediator has proved to be a crucial, and general, nuclear receptor-interacting coactivator, with demonstrated functions in transcription steps ranging from chromatin remodeling to subsequent PIC formation and function. Here we discuss (i) our current understanding of pathways that nuclear receptors and other interacting cofactors employ to recruit Mediator to target gene enhancers and promoters, including conditional requirements for the strong NR-Mediator interactions mediated by the NR AF2 domain and the MED1 LXXLLL motifs and (ii) mechanisms by which Mediator acts to transmit signals from enhancer-bound nuclear receptors to the general transcription machinery at core promoters to effect PIC formation and function.

  9. A computational description of simple mediation analysis

    Caron, Pier-Olivier

    2018-04-01

    Full Text Available Simple mediation analysis is an increasingly popular statistical analysis in psychology and in other social sciences. However, there is very few detailed account of the computations within the model. Articles are more often focusing on explaining mediation analysis conceptually rather than mathematically. Thus, the purpose of the current paper is to introduce the computational modelling within simple mediation analysis accompanied with examples with R. Firstly, mediation analysis will be described. Then, the method to simulate data in R (with standardized coefficients will be presented. Finally, the bootstrap method, the Sobel test and the Baron and Kenny test all used to evaluate mediation (i.e., indirect effect will be developed.

    2018-01-01

    After the implementation of the universal two-child policy in 2016, more and more working women have found themselves caught in the dilemma of whether to raise a baby or be promoted, which exacerbates work–family conflicts among Chinese women. Few studies have examined the mediating effect of negative affect. The present study combined the conservation of resources model and affective events theory to examine the sequential mediating effect of negative affect and perceived stress in the relationship between work–family conflict and mental health. A valid sample of 351 full-time Chinese female employees was recruited in this study, and participants voluntarily answered online questionnaires. Pearson correlation analysis, structural equation modeling, and multiple mediation analysis were used to examine the relationships between work–family conflict, negative affect, perceived stress, and mental health in full-time female employees. We found that women’s perceptions of both work-to-family conflict and family-to-work conflict were significant negatively related to mental health. Additionally, the results showed that negative affect and perceived stress were negatively correlated with mental health. The 95% confidence intervals indicated the sequential mediating effect of negative affect and stress in the relationship between work–family conflict and mental health was significant, which supported the hypothesized sequential mediation model. The findings suggest that work–family conflicts affected the level of self-reported mental health, and this relationship functioned through the two sequential mediators of negative affect and perceived stress.

  14. Atomic Force Microscope Mediated Chromatography

    Anderson, Mark S.

    2013-01-01

    The atomic force microscope (AFM) is used to inject a sample, provide shear-driven liquid flow over a functionalized substrate, and detect separated components. This is demonstrated using lipophilic dyes and normal phase chromatography. A significant reduction in both size and separation time scales is achieved with a 25-micron-length column scale, and one-second separation times. The approach has general applications to trace chemical and microfluidic analysis. The AFM is now a common tool for ultra-microscopy and nanotechnology. It has also been demonstrated to provide a number of microfluidic functions necessary for miniaturized chromatography. These include injection of sub-femtoliter samples, fluidic switching, and sheardriven pumping. The AFM probe tip can be used to selectively remove surface layers for subsequent microchemical analysis using infrared and tip-enhanced Raman spectroscopy. With its ability to image individual atoms, the AFM is a remarkably sensitive detector that can be used to detect separated components. These diverse functional components of microfluidic manipulation have been combined in this work to demonstrate AFM mediated chromatography. AFM mediated chromatography uses channel-less, shear-driven pumping. This is demonstrated with a thin, aluminum oxide substrate and a non-polar solvent system to separate a mixture of lipophilic dyes. In conventional chromatographic terms, this is analogous to thin-layer chromatography using normal phase alumina substrate with sheardriven pumping provided by the AFM tip-cantilever mechanism. The AFM detection of separated components is accomplished by exploiting the variation in the localized friction of the separated components. The AFM tip-cantilever provides the mechanism for producing shear-induced flows and rapid pumping. Shear-driven chromatography (SDC) is a relatively new concept that overcomes the speed and miniaturization limitations of conventional liquid chromatography. SDC is based on a

  17. The TIM and TAM families of phosphatidylserine receptors mediate dengue virus entry.

    Meertens, Laurent; Carnec, Xavier; Lecoin, Manuel Perera; Ramdasi, Rasika; Guivel-Benhassine, Florence; Lew, Erin; Lemke, Greg; Schwartz, Olivier; Amara, Ali

    2012-10-18

    Dengue viruses (DVs) are responsible for the most medically relevant arboviral diseases. However, the molecular interactions mediating DV entry are poorly understood. We determined that TIM and TAM proteins, two receptor families that mediate the phosphatidylserine (PtdSer)-dependent phagocytic removal of apoptotic cells, serve as DV entry factors. Cells poorly susceptible to DV are robustly infected after ectopic expression of TIM or TAM receptors. Conversely, DV infection of susceptible cells is inhibited by anti-TIM or anti-TAM antibodies or knockdown of TIM and TAM expression. TIM receptors facilitate DV entry by directly interacting with virion-associated PtdSer. TAM-mediated infection relies on indirect DV recognition, in which the TAM ligand Gas6 acts as a bridging molecule by binding to PtdSer within the virion. This dual mode of virus recognition by TIM and TAM receptors reveals how DVs usurp the apoptotic cell clearance pathway for infectious entry. Copyright © 2012 Elsevier Inc. All rights reserved.

  18. Posttraumatic Stress, Family Functioning, and Externalizing in Adolescents Exposed to Violence: A Moderated Mediation Model.

    2016-09-02

    Exposure to community violence disproportionately impacts low-income, minority youth and is associated with posttraumatic stress symptoms and maladaptive adjustment. This study investigates whether posttraumatic stress mediates the relation between exposure to community violence and externalizing symptoms and the moderating role of family cohesion and daily family support in buffering these effects on later externalizing. Low-income, African American 7th-grade students (M age = 12.57 years; N = 254) from high-crime neighborhoods participated in a 2-year longitudinal study measuring the effects of community violence exposure. The students completed questionnaires administered by research staff over 5 consecutive days for each year of the study. Family cohesion and daily family support exhibited a significant buffering effect for several outcomes. Posttraumatic stress significantly mediated the effect of witnessing community violence on subsequent aggression. The strength of these indirect effects depended on level of family cohesion. The findings provide evidence in support of interventions provided at both individual and family levels. Mental health providers working with this population should be aware of the intertwined nature of exposure to community violence, posttraumatic stress, and subsequent maladaptive outcomes.

  19. Risky family processes prospectively forecast shorter telomere length mediated through negative emotions.

    Brody, Gene H; Yu, Tianyi; Shalev, Idan

    2017-05-01

    This study was designed to examine prospective associations of risky family environments with subsequent levels of negative emotions and peripheral blood mononuclear cell telomere length (TL), a marker of cellular aging. A second purpose was to determine whether negative emotions mediate the hypothesized link between risky family processes and diminished telomere length. Participants were 293 adolescents (age 17 years at the first assessment) and their primary caregivers. Caregivers provided data on risky family processes when the youths were age 17 years, youths reported their negative emotions at age 18 years, and youths' TL was assayed from a blood sample at age 22 years. The results revealed that (a) risky family processes forecast heightened negative emotions (β = .316, p emotions forecast shorter TL (β = -.187, p = .012), and (c) negative emotions served as a mediator connecting risky family processes with diminished TL (indirect effect = -0.012, 95% CI [-0.036, -0.002]). These findings are consistent with the hypothesis that risky family processes presage premature cellular aging through effects on negative emotions, with potential implications for lifelong health.

  20. Mediational Model of Multiple Sclerosis Impairments, Family Needs, and Caregiver Mental Health in Guadalajara, Mexico

    Melody N. Mickens

    2018-01-01

    Full Text Available Individuals with multiple sclerosis (MS, especially those living in Latin America, often require assistance from family caregivers throughout the duration of the disease. Previous research suggests that family caregivers may experience positive and negative outcomes from providing care to individuals with MS, but few studies have examined the unmet needs of individuals providing care to family members with MS and how these unmet needs may mediate the relationship between MS symptoms and caregiver mental health. The current study examined the relationships among MS impairments (functional, neurological, cognitive, behavioral, and emotional, unmet family needs (household, informational, financial, social support, and health, and caregiver mental health (satisfaction with life, anxiety, burden, and depression in a sample of 81 MS caregivers from Guadalajara, Mexico. A structural equation model demonstrated the mediational effect of unmet family needs on the relationship between MS impairments and caregiver mental health. These findings suggest that intervention research on MS caregivers in Latin America may consider focusing on caregiver mental health problems by addressing unmet family needs and teaching caregivers ways to manage the impairments of the individual with MS.

  1. Emotional well-being in children with epilepsy: Family factors as mediators and moderators.

    Goodwin, Shane W; Wilk, Piotr; Karen Campbell, M; Speechley, Kathy N

    2017-11-01

    Our objective was to examine the relationships of factors associated with children's emotional well-being 2 years after diagnosis, and to examine if these relationships are mediated or moderated by family factors. Data came from a multicenter prospective cohort study of children with newly diagnosed epilepsy from across Canada (Health-Related Quality of Life in Children with Epilepsy Study; HERQULES, n = 373). Emotional well-being was assessed using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55). The relationships between clinical factors, family factors, and emotional well-being were assessed using multiple regression analyses. Family functioning, family stress, and repertoire of resources that the families had to adapt to stressful events were significantly associated with poor emotional well-being 2 years after diagnosis (p < 0.05) in the multivariable analysis. The effect of parental depressive symptoms was partially mediated by family functioning and family stress (p < 0.01 and p = 0.02, respectively). Family resources acted as a moderator in the relationship between severity of epilepsy and emotional well-being (p < 0.05). Based on our findings, efforts to strengthen the family environment may warrant attention. We suggest that clinicians take a family centered care approach by including families in treatment planning. Family centered care has been shown to improve family well-being and coping and in turn may reduce the impact of clinical factors on emotional well-being to improve long-term health-related quality of life.

    Dopamine (DA), a neurotransmitter in the central nervous system (CNS), has modulatory functions at the systemic level. The peripheral and central nervous systems have independent dopaminergic system (DAS) that share mechanisms and molecular machinery. In the past century, experimental evidence has accumulated on the proteins knowledge that is involved in the synthesis, reuptake, and transportation of DA in leukocytes and the differential expression of the D1-like (D1R and D5R) and D2-like receptors (D2R, D3R, and D4R). The expression of these components depends on the state of cellular activation and the concentration and time of exposure to DA. Receptors that are expressed in leukocytes are linked to signaling pathways that are mediated by changes in cAMP concentration, which in turn triggers changes in phenotype and cellular function. According to the leukocyte lineage, the effects of DA are associated with such processes as respiratory burst, cytokine and antibody secretion, chemotaxis, apoptosis, and cytotoxicity. In clinical conditions such as schizophrenia, Parkinson disease, Tourette syndrome, and multiple sclerosis (MS), there are evident alterations during immune responses in leukocytes, in which changes in DA receptor density have been observed. Several groups have proposed that these findings are useful in establishing clinical status and clinical markers. PMID:27795960

    2017-05-10

    Disruption of foraging using oversupply of ant trail pheromones is a novel pest management application under investigation. It presents an opportunity to investigate the interaction of sensory modalities by removal of one of the modes. Superficially similar to sex pheromone-based mating disruption in moths, ant trail pheromone disruption lacks an equivalent mechanistic understanding of how the ants respond to an oversupply of their trail pheromone. Since significant compromise of one sensory modality essential for trail following (chemotaxis) has been demonstrated, we hypothesised that other sensory modalities such as thigmotaxis could act to reduce the impact on olfactory disruption of foraging behaviour. To test this, we provided a physical stimulus of thread to aid trailing by Argentine ants otherwise under disruptive pheromone concentrations. Trail following success was higher using a physical cue. While trail integrity reduced under continuous over-supply of trail pheromone delivered directly on the thread, provision of a physical cue in the form of thread slightly improved trail following and mediated trail disruption from high concentrations upwind. Our results indicate that ants are able to use physical structures to reduce but not eliminate the effects of trail pheromone disruption.

  5. Stigma by association and family burden among family members of people with mental illness: the mediating role of coping.

    van der Sanden, Remko L M; Pryor, John B; Stutterheim, Sarah E; Kok, Gerjo; Bos, Arjan E R

    2016-09-01

    When someone has a mental illness, family members may share the experience of stigma. Past research has established that family members' experiences of stigma by association predict psychological distress and lower quality-of-life. The present study, conducted with 503 family members of people with mental illness examined the prevalence of 14 different coping strategies. Of greater importance, we examined the role of these coping strategies as mediators of the relationships between stigma by association and family burden, on the one hand, and outcomes, such as psychological distress and quality-of-life, on the other. The results showed that both perceived stigma by association and family burden are associated with greater psychological distress and lower quality-of-life, and that most coping strategies mediate these relationships. Adaptive coping strategies were related to reduced negative outcomes, while most maladaptive coping strategies were related to enhanced negative outcomes. Implications for intervention development are discussed.

  7. Mediators and moderators in early intervention research.

    Breitborde, Nicholas J K; Srihari, Vinod H; Pollard, Jessica M; Addington, Donald N; Woods, Scott W

    2010-05-01

    The goal of this paper is to provide clarification with regard to the nature of mediator and moderator variables and the statistical methods used to test for the existence of these variables. Particular attention will be devoted to discussing the ways in which the identification of mediator and moderator variables may help to advance the field of early intervention in psychiatry. We completed a literature review of the methodological strategies used to test for mediator and moderator variables. Although several tests for mediator variables are currently available, recent evaluations suggest that tests which directly evaluate the indirect effect are superior. With regard to moderator variables, two approaches ('pick-a-point' and regions of significance) are available, and we provide guidelines with regard to how researchers can determine which approach may be most appropriate to use for their specific study. Finally, we discuss how to evaluate the clinical importance of mediator and moderator relationships as well as the methodology to calculate statistical power for tests of mediation and moderation. Further exploration of mediator and moderator variables may provide valuable information with regard to interventions provided early in the course of a psychiatric illness.

  8. Function and regulation of the Mediator complex.

    Conaway, Ronald C; Conaway, Joan Weliky

    2011-04-01

    Over the past few years, advances in biochemical and genetic studies of the structure and function of the Mediator complex have shed new light on its subunit architecture and its mechanism of action in transcription by RNA polymerase II (pol II). The development of improved methods for reconstitution of recombinant Mediator subassemblies is enabling more in-depth analyses of basic features of the mechanisms by which Mediator interacts with and controls the activity of pol II and the general initiation factors. The discovery and characterization of multiple, functionally distinct forms of Mediator characterized by the presence or absence of the Cdk8 kinase module have led to new insights into how Mediator functions in both Pol II transcription activation and repression. Finally, progress in studies of the mechanisms by which the transcriptional activation domains (ADs) of DNA binding transcription factors target Mediator have brought to light unexpected complexities in the way Mediator participates in signal transduction.

  9. LMX, Breach Perceptions, Work-Family Conflict, and Well-Being: A Mediational Model.

    Hill, Rachel T; Morganson, Valerie J; Matthews, Russell A; Atkinson, Theresa P

    2016-01-01

    Despite research advances, work-family scholars still lack an understanding of how leadership constructs relate to an employee's ability to effectively manage the work-family interface. In addition, there remains a need to examine the process through which leadership and work-family conflict influence well-being outcomes. Using a sample of 312 workers, a mediated process model grounded in social exchange theory is tested wherein the authors seek to explain how leaders shape employee perceptions, which, in turn, impact organizational fulfillment of expectations (i.e., psychological contract breach), work-family conflict, and well-being. A fully latent structural equation model was used to test study hypotheses, all of which were supported. Building on existing theory, findings suggest that the supervisor plays a critical role as a frontline representative for the organization and that work-family conflict is reduced and well-being enhanced through a process of social exchange between the supervisor and worker.

  11. Family incivility and job performance: a moderated mediation model of psychological distress and core self-evaluation.

    Lim, Sandy; Tai, Kenneth

    2014-03-01

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

    In this work we briefly review the theoretical basis for the electrochemical rectification in mediated redox reactions at redox polymer modified electrodes. Electrochemical rectification may have two distinct origins. It is either caused by a slow kinetics of the reaction between the external redox couple and the mediator or it is originated by a slow electronic transport within the film under an unfavorable thermodynamic condition. We show experimental results for the redox mediation reaction of poly(o-aminophenol) (POAP) on the Fe{sup 2+/3+} and on the Fe(CN){sub 6}{sup 3-/4-} redox couples in solution that prove the proposed mechanisms of electrochemical rectification.

  14. Singlet deflected anomaly/gauge mediation

    Blas, J. de; Delgado, A.

    2012-01-01

    We study an extension of the standard anomaly/gauge mediation scenario where the messenger fields have direct interactions with an extra gauge singlet. This realizes a phenomenologically viable NMSSM-like scenario free of the μ-b μ problem. Current cosmological constraints imply a small size for the anomaly-mediation contributions, unless some source of R-parity violation is permitted. In the latter case the allowed regions in the parameter space can be substantially larger than in the corresponding gauge-mediation scenario.

  16. CELLULAR INTERACTIONS MEDIATED BY GLYCONECTIDS

    O.Popescu

    1999-01-01

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

    The sweet spot supersymmetry (SUSY) solves the μ/B{sub μ} problem in the Minimal Supersymmetric Standard Model (MSSM) with gauge mediated SUSY breaking (GMSB) via the generalized Giudice-Masiero (GM) mechanism where only the μ-term and soft Higgs masses are generated at the unification scale of the Grand Unified Theory (GUT) due to the approximate PQ symmetry. Because all the other SUSY breaking soft terms are generated via the GMSB below the GUT scale, there exists SUSY electroweak (EW) fine-tuning problem to explain the 125 GeV Higgs boson mass due to small trilinear soft term. Thus, to explain the Higgs boson mass, we propose the GMSB with both the generalized GM mechanism and Higgs-messenger interactions. The renormalization group equations are runnings from the GUT scale down to EW scale. So the EW symmetry breaking can be realized easier. We can keep the gauge coupling unification and solution to the flavor problem in the GMSB, as well as solve the μ/B{sub μ}-problem. Moreover, there are only five free parameters in our model. So we can determine the characteristic low energy spectra and explore its distinct phenomenology. The fine-tuning measure can be as low as 100. For some benchmark points, the stop mass can be as low as 1.7 TeV while the glunio mass is around 2.5 TeV. The gravitino dark matter can come from a thermal production with the correct relic density and be consistent with the thermal leptogenesis. Because gluino and stop can be relatively light in our model, how to search for such GMSB at the upcoming run II of the LHC experiment could be very interesting.

  18. Causal mediation analysis with multiple mediators in the presence of treatment noncompliance.

    Park, Soojin; Kürüm, Esra

    2018-05-20

    Randomized experiments are often complicated because of treatment noncompliance. This challenge prevents researchers from identifying the mediated portion of the intention-to-treated (ITT) effect, which is the effect of the assigned treatment that is attributed to a mediator. One solution suggests identifying the mediated ITT effect on the basis of the average causal mediation effect among compliers when there is a single mediator. However, considering the complex nature of the mediating mechanisms, it is natural to assume that there are multiple variables that mediate through the causal path. Motivated by an empirical analysis of a data set collected in a randomized interventional study, we develop a method to estimate the mediated portion of the ITT effect when both multiple dependent mediators and treatment noncompliance exist. This enables researchers to make an informed decision on how to strengthen the intervention effect by identifying relevant mediators despite treatment noncompliance. We propose a nonparametric estimation procedure and provide a sensitivity analysis for key assumptions. We conduct a Monte Carlo simulation study to assess the finite sample performance of the proposed approach. The proposed method is illustrated by an empirical analysis of JOBS II data, in which a job training intervention was used to prevent mental health deterioration among unemployed individuals.

  19. Work–Family Conflict and Mental Health Among Female Employees: A Sequential Mediation Model via Negative Affect and Perceived Stress

    Shiyi Zhou; Shu Da; Heng Guo; Xichao Zhang

    2018-01-01

    After the implementation of the universal two-child policy in 2016, more and more working women have found themselves caught in the dilemma of whether to raise a baby or be promoted, which exacerbates work–family conflicts among Chinese women. Few studies have examined the mediating effect of negative affect. The present study combined the conservation of resources model and affective events theory to examine the sequential mediating effect of negative affect and perceived stress in the relat...

  20. Parental alcohol use disorders and child delinquency: the mediating effects of executive functioning and chronic family stress.

    Grekin, Emily R; Brennan, Patricia A; Hammen, Constance

    2005-01-01

    This study examines the relationship between parental alcohol use disorders (AUDs) and child violent and nonviolent delinquency. It also explores the mediating effects of executive functioning and chronic family stress on the parental AUD/child delinquency relationship. Participants were 816 families with children (414 boys and 402 girls) born between 1981 and 1984 at Mater Misericordiae Mother's Hospital in Brisbane, Australia. Parents and children completed semistructured interviews, questionnaires and neuropsychological tests that assessed parental alcohol use, family psychiatric history, chronic family stress, child delinquency and child executive functioning. Paternal (but not maternal) AUDs predicted child violent and nonviolent delinquency. Executive functioning mediated the relationship between paternal AUDs and violent delinquency, whereas family stress mediated the relationship between paternal AUDs and both violent and nonviolent delinquency. Results support a biosocial conceptualization of the paternal AUD/delinquency relationship. They suggest that paternal AUDs may be associated with child executive functioning and family stress, which may in turn lead to child delinquency.

  1. Work-family and family-work conflict: does intrinsic-extrinsic satisfaction mediate the prediction of general job satisfaction?

    Calvo-Salguero, Antonia; Martínez-De-Lecea, José-María Salinas; Carrasco-González, Ana-María

    2011-01-01

    The objective of this study is to analyze the mediating role of intrinsic and extrinsic job satisfaction in the relationship between the 2 dimensions of work-family conflict-family interfering with work (FIW) and work interfering with family (WIF)-and general job satisfaction. Step-by-step hierarchical regression analyses were carried out on a sample of 151 men and women from a Spanish public organization. The results confirmed the mediating role of intrinsic job satisfaction in the case of FIW. This highlights the importance of taking into account the level of satisfaction with the intrinsic facets of one's job as a measure for understanding why FIW has a negative impact on general job satisfaction.

  3. Dark matter prospects in deflected mirage mediation

    Holmes, Michael; Nelson, Brent D.

    2009-01-01

    The recently introduced deflected mirage mediation (DMM) model is a string-motivated paradigm in which all three of the major supersymmetry-breaking transmission mechanisms are operative. We begin a systematic exploration of the parameter space of this rich model context, paying special attention to the pattern of gaugino masses which arise. In this work we focus on the dark matter phenomenology of the DMM model as such signals are the least influenced by the model-dependent scalar masses. We find that a large portion of the parameter space in which the three mediation mechanisms have a similar effective mass scale of 1 TeV or less will be probed by future direct and indirect detection experiments. Distinguishing deflected mirage mediation from the mirage model without gauge mediation will prove difficult without collider input, though we indicate how gamma ray signals may provide an opportunity for distinguishing between the two paradigms

  4. Selecting a model of supersymmetry breaking mediation

    AbdusSalam, S. S.; Allanach, B. C.; Dolan, M. J.; Feroz, F.; Hobson, M. P.

    2009-01-01

    We study the problem of selecting between different mechanisms of supersymmetry breaking in the minimal supersymmetric standard model using current data. We evaluate the Bayesian evidence of four supersymmetry breaking scenarios: mSUGRA, mGMSB, mAMSB, and moduli mediation. The results show a strong dependence on the dark matter assumption. Using the inferred cosmological relic density as an upper bound, minimal anomaly mediation is at least moderately favored over the CMSSM. Our fits also indicate that evidence for a positive sign of the μ parameter is moderate at best. We present constraints on the anomaly and gauge mediated parameter spaces and some previously unexplored aspects of the dark matter phenomenology of the moduli mediation scenario. We use sparticle searches, indirect observables and dark matter observables in the global fit and quantify robustness with respect to prior choice. We quantify how much information is contained within each constraint.

  5. Unwrapping Court-Connected Mediation Agreements

    Adrian, Lin; Mykland, Solfrid

    2018-01-01

    Court-connected mediated agreements seem to both fulfil and fail the ideal of self-determination in mediation theory. In a study of 134 agreements from court-connected mediation, we found that the majority of agreements contain creative elements and display great variation in the provisions...... and understand them. The judicial language is well known for the drafters of the agreement but not the parties. Thus, court-connected mediation seems to fail aspects of self-determination when it comes to drafting agreements. We draw on new-institutional theory when we explore and explain this apparent...... they contain. These results indicate that the parties play an important role in crafting the substance of their agreements. However, we also found that the wording of the agreements is characterised by legal and bureaucratic language to the extent that people without legal training find it difficult to read...

  7. BOOKTUBERS MOVEMENT: EMERGING PRACTICES OF READING MEDIATION

    Claudia Souza Teixeira

    2016-12-01

    Full Text Available This paper intents to investigate reading mediation practices develop by the booktubers, young people that use the YouTube in order to share information about books and to interact with other readers. We begin presenting some concepts related to reading and mediation activities, and then, talk about some aspects of cyberspace, the formation of virtual communities and the Booktubers phenomena. At last, as a result of a documental analysis of 100 videos posted by booktubers, we show the characteristics of these emerging mediation reading practices and the types of books that are more commented by them. We conclude that the conventional practices of reading mediation are the bases for the booktubers’ actuation, but they are adapted to the new kinds of elaboration, creation and organization enabled by the Internet.

  8. A randomised controlled trial evaluating family mediated exercise (FAME therapy following stroke

    Stokes Emma

    2008-06-01

    Full Text Available Abstract Background Stroke is a leading cause of disability among adults worldwide. Evidence suggests that increased duration of exercise therapy following stroke has a positive impact on functional outcome following stroke. The main objective of this randomised controlled trial is to evaluate the impact of additional family assisted exercise therapy in people with acute stroke. Methods/Design A prospective multi-centre single blind randomised controlled trial will be conducted. Forty patients with acute stroke will be randomised into either an experimental or control group. The experimental group will receive routine therapy and additional lower limb exercise therapy in the form of family assisted exercises. The control group will receive routine therapy with no additional formal input from their family members. Participants will be assessed at baseline, post intervention and followed up at three months using a series of standardised outcome measures. A secondary aim of the project is to evaluate the impact of the family mediated exercise programme on the person with stroke and the individual(s assisting in the delivery of exercises using a qualitative methodology. The study has gained ethical approval from the Research Ethics Committees of each of the clinical sites involved in the study. Discussion This study will evaluate a structured programme of exercises that can be delivered to people with stroke by their 'family members/friends'. Given that the progressive increase in the population of older people is likely to lead to an increased prevalence of stroke in the future, it is important to reduce the burden of this illness on the individual, the family and society. Family mediated exercises can maximise the carry over outside formal physiotherapy sessions, giving patients the opportunity for informal practice. Trial Registration The protocol for this study is registered with the US NIH Clinical trials registry (NCT00666744

  9. Mediated moderation or moderated mediation: relationship between length of unemployment, resilience, coping and health.

    Sojo, Víctor; Guarino, Leticia

    2011-05-01

    The aim of the present research was to evaluate a model of mediated moderation vs. moderated mediation that could explain the relationship between length of unemployment, dispositional resilience, coping styles and depression and social functioning of Venezuelan unemployed individuals. Self-report measures were administered to a sample of 328 unemployed residents in Caracas, Venezuela. Results indicated that emotional coping acted as a mediator in the relationship between resilience and depression. Individuals with greater resilience used more detachment coping when unemployment was longer, while individuals with poorer resilience in the same situation used less avoidance coping. Resilience acted as a protective moderating factor between longer periods of unemployment and social functioning, a process mediated by detachment coping. Overall, results supported a mediated moderation model, with resilience as the moderating factor and coping as the mediator in the relation between stress due to the length of unemployment and well-being.

    An essential goal of program evaluation and scientific research is the investigation of causal mechanisms. Over the past several decades, causal mediation analysis has been used in medical and social sciences to decompose the treatment effect into the natural direct and indirect effects. However, all of the existing mediation analysis methods rely on parametric modeling assumptions in one way or another, typically requiring researchers to specify multiple regression models involving the treat...

    2013-12-01

    web technologies, including ontologies and a semantic mediator. The semantically-enhanced SPEGG allowed a client to submit a single query (e.g. ';hills') and to retrieve data from two separate gazetteers with different vocabularies (e.g. where one refers to ';summits' another refers to ';hills'). Supporting the SPEGG was a SPARQL server that held the ontologies and processed queries on them. Earth Science surveys and forecast always have a place on Earth. Being able to share the information about a place and solve inconsistencies about that place from different sources will enable geoscientists to better do their research. In the advent of mobile geo computing and location based services (LBS), brokering gazetteers will provide geoscientists with access to gazetteer services rich with information and functionality beyond that offered by current generic gazetteers.

  17. Ombuds’ corner: Consider mediation - some rules

    Vincent Vuillemin

    2013-01-01

    Mediation is a structured process in which an external party, called a mediator, helps participants generate and evaluate options that would allow them to reach a mutual agreement. It is an informal and confidential process.   The mediator does not have the power to impose an agreement on the parties, who should find it by themselves. However, the mediator controls the process. He arranges the meetings in agreement with the parties, and coordinates the details (concerning the speaking times, for example) and ensures that the parties respect of the rules which have been agreed on. He also favours advancing of the process towards a solution. The mediation process is centred on the search for a solution and a mutual agreement. In such a process, the mediator takes a neutral and impartial position, and does not advocate for a single party. He favours good communication between the parties, and will ensure that mutual respect is maintained and that the correct language is used during the discussi...

  18. Flavorful hybrid anomaly-gravity mediation

    Gross, Christian; Hiller, Gudrun

    2011-01-01

    We consider supersymmetric models where anomaly and gravity mediation give comparable contributions to the soft terms and discuss how this can be realized in a five-dimensional brane world. The gaugino mass pattern of anomaly mediation is preserved in such a hybrid setup. The flavorful gravity-mediated contribution cures the tachyonic slepton problem of anomaly mediation. The supersymmetric flavor puzzle is solved by alignment. We explicitly show how a working flavor-tachyon link can be realized with Abelian flavor symmetries and give the characteristic signatures of the framework, including O(1) slepton mass splittings between different generations and between doublets and singlets. This provides opportunities for same flavor dilepton edge measurements with missing energy at the Large Hadron Collider (LHC). Rare lepton decay rates could be close to their current experimental limit. Compared to pure gravity mediation, the hybrid model is advantageous because it features a heavy gravitino which can avoid the cosmological gravitino problem of gravity-mediated models combined with leptogenesis.

    The development of sensitive cryogenic light detectors is of primary interest for bolometric experiments searching for rare events like dark matter interactions or neutrino-less double beta decay. Thanks to their good energy resolution and the natural multiplexed read-out, Kinetic Inductance Detectors (KIDs) are particularly suitable for this purpose. To efficiently couple KIDs-based light detectors to the large crystals used by the most advanced bolometric detectors, active surfaces of several cm 2 are needed. For this reason, we are developing phonon-mediated detectors. In this paper, we present the results obtained with a prototype consisting of four 40 nm thick aluminum resonators patterned on a 2 × 2 cm 2 silicon chip, and calibrated with optical pulses and X-rays. The detector features a noise resolution σ E  = 154 ± 7 eV and an (18 ± 2)% efficiency

  3. Assessing moderated mediation in linear models requires fewer confounding assumptions than assessing mediation.

    Loeys, Tom; Talloen, Wouter; Goubert, Liesbet; Moerkerke, Beatrijs; Vansteelandt, Stijn

    2016-11-01

    It is well known from the mediation analysis literature that the identification of direct and indirect effects relies on strong no unmeasured confounding assumptions of no unmeasured confounding. Even in randomized studies the mediator may still be correlated with unobserved prognostic variables that affect the outcome, in which case the mediator's role in the causal process may not be inferred without bias. In the behavioural and social science literature very little attention has been given so far to the causal assumptions required for moderated mediation analysis. In this paper we focus on the index for moderated mediation, which measures by how much the mediated effect is larger or smaller for varying levels of the moderator. We show that in linear models this index can be estimated without bias in the presence of unmeasured common causes of the moderator, mediator and outcome under certain conditions. Importantly, one can thus use the test for moderated mediation to support evidence for mediation under less stringent confounding conditions. We illustrate our findings with data from a randomized experiment assessing the impact of being primed with social deception upon observer responses to others' pain, and from an observational study of individuals who ended a romantic relationship assessing the effect of attachment anxiety during the relationship on mental distress 2 years after the break-up. © 2016 The British Psychological Society.

  4. Combined gauge-mediated and anomaly-mediated supersymmetry breaking and conformal sequestering

    Sundrum, Raman

    2005-01-01

    Anomaly-mediated supersymmetry breaking in the context of 4D conformally sequestered models is combined with Poppitz-Trivedi D-type gauge-mediation. The implementation of the two mediation mechanisms naturally leads to visible soft masses at the same scale so that they can cooperatively solve the μ and flavor problems of weak scale supersymmetry, as well as the tachyonic-slepton problem of pure anomaly-mediation. The tools are developed in a modular fashion for more readily fitting into the general program of optimizing supersymmetric dynamics in hunting for the most attractive weak scale phenomenologies combined with Planck-scale plausibility

  6. Parents' Relative Socioeconomic Status and Paternal Involvement in Chinese Families: The Mediating Role of Coparenting.

    Liu, Chang; Wu, Xinchun; Zou, Shengqi

    2016-01-01

    This study examined the mediating role of coparenting in the association between differences/similarities in paternal and maternal socioeconomic status (SES) and paternal involvement in Chinese families. The sample included 244 couples with children aged 3-7 years. Fathers and mothers reported their individual incomes, educational levels, occupations, and coparenting behavior (measured using the Coparenting Scale), and fathers completed the Father Involvement Questionnaire. Structural equation modeling was performed to examine the associations between SES and paternal involvement. Results suggested that SES indicator measures were outcome specific. Occupational differences/similarities were associated with paternal involvement indirectly, via fathers' family integrity practices. Income and educational differences/similarities did not affect paternal involvement. The results suggested that the traditional Chinese view that "men are chiefly responsible for activity in society, while women are responsible for the home" has faded.

  7. Family dynamics and alcohol and marijuana use among adolescents: The mediating role of negative emotional symptoms and sensation seeking.

    Trujillo, Ángela; Obando, Diana; Trujillo, Carlos A

    2016-11-01

    The literature indicates a close relationship between family dynamics and psychoactive substance use among adolescents, and multi-causality among substance use-related problems, including personal adolescent characteristics as potential influential aspects in this relationship. The purpose of this study is to investigate the role of emotional symptoms and sensation seeking as mediators in the relationship between family dynamics and alcohol and marijuana use among adolescents. The sample consisted of 571 high school students with a mean age of 14.63, who completed the Communities That Care Youth Survey in its Spanish version. We propose and test a mediation-in-serial model to identify the relationships between the study variables. The results of the mediation models indicate that, in most cases, the relationship between family dynamics and the substance use variables is meaningfully carried through the proposed mediators, first through negative emotional symptoms, and then through sensation seeking. The meaning of the mediation varies as a function of the facet of family dynamics (conflict or attachment) and the use aspect (age of onset, frequency of use, and use intention). We discuss the implications of these findings for intervention and prevention strategies. Copyright © 2016 Elsevier Ltd. All rights reserved.

  8. Transcription-factor-mediated DNA looping probed by high-resolution, single-molecule imaging in live E. coli cells.

    Zach Hensel

    Full Text Available DNA looping mediated by transcription factors plays critical roles in prokaryotic gene regulation. The "genetic switch" of bacteriophage λ determines whether a prophage stays incorporated in the E. coli chromosome or enters the lytic cycle of phage propagation and cell lysis. Past studies have shown that long-range DNA interactions between the operator sequences O(R and O(L (separated by 2.3 kb, mediated by the λ repressor CI (accession number P03034, play key roles in regulating the λ switch. In vitro, it was demonstrated that DNA segments harboring the operator sequences formed loops in the presence of CI, but CI-mediated DNA looping has not been directly visualized in vivo, hindering a deep understanding of the corresponding dynamics in realistic cellular environments. We report a high-resolution, single-molecule imaging method to probe CI-mediated DNA looping in live E. coli cells. We labeled two DNA loci with differently colored fluorescent fusion proteins and tracked their separations in real time with ∼40 nm accuracy, enabling the first direct analysis of transcription-factor-mediated DNA looping in live cells. Combining looping measurements with measurements of CI expression levels in different operator mutants, we show quantitatively that DNA looping activates transcription and enhances repression. Further, we estimated the upper bound of the rate of conformational change from the unlooped to the looped state, and discuss how chromosome compaction may impact looping kinetics. Our results provide insights into transcription-factor-mediated DNA looping in a variety of operator and CI mutant backgrounds in vivo, and our methodology can be applied to a broad range of questions regarding chromosome conformations in prokaryotes and higher organisms.

  9. Heat-shock stress activates a novel nuclear import pathway mediated by Hikeshi

    Imamoto, Naoko; Kose, Shingo

    2012-01-01

    Cellular stresses significantly affect nuclear transport systems. Nuclear transport pathways mediated by importin β-family members, which are active under normal conditions, are downregulated. During thermal stress, a nuclear import pathway mediated by a novel carrier, which we named Hikeshi, becomes active. Hikeshi is not a member of the importin β family and mediates the nuclear import of Hsp70s. Unlike importin β family-mediated nuclear transport, the Hikeshi-mediated nuclear import of Hsp...

    2012-01-01

    The present study investigates the relationship between trait mindfulness and work-family balance among a sample of working parents. Sleep quality and vitality are tested as mediators of this relationship. Results indicate that those with greater mindfulness report greater work-family balance, better sleep quality, and greater vitality. As…

  17. Family Resources and Mid-Life Level of Education: A Longitudinal Study of the Mediating Influence of Childhood Parental Involvement

    von Otter, Cecilia

    2014-01-01

    This paper draws on the concept of parental involvement, popular among educators and policy-makers, in investigating differences in level of attained education by family background. The question is if parental involvement in children's schooling at age 14 acts as a mediator between family resources and mid-life level of attained education. Using…

    2014-03-01

    The concepts and associated analyses of mediation and moderation are important to the field of psychology. Although pediatric psychologists frequently incorporate mediation and moderation in their theories and empirical research, on few occasions have we integrated mediation and moderation. In this article, conceptual reasons for integrating mediation and moderation are offered. We illustrate a model that integrates mediation and moderation. In our illustration, the strength of an indirect or a mediating effect varied as a function of a moderating variable. Clinical implications of the integration of mediation and moderation are discussed, as is the potential of integrated models to advance research programs in pediatric psychology.

  19. Guidelines for the Investigation of Mediating Variables in Business Research.

    MacKinnon, David P; Coxe, Stefany; Baraldi, Amanda N

    2012-03-01

    Business theories often specify the mediating mechanisms by which a predictor variable affects an outcome variable. In the last 30 years, investigations of mediating processes have become more widespread with corresponding developments in statistical methods to conduct these tests. The purpose of this article is to provide guidelines for mediation studies by focusing on decisions made prior to the research study that affect the clarity of conclusions from a mediation study, the statistical models for mediation analysis, and methods to improve interpretation of mediation results after the research study. Throughout this article, the importance of a program of experimental and observational research for investigating mediating mechanisms is emphasized.

    The conserved Mediator co-activator complex has an essential role in the regulation of RNA polymerase II transcription in all eukaryotes. Understanding the structure and interactions of Mediator is crucial for determining how the complex influences transcription initiation and conveys regulatory information to the basal transcription machinery. Here we present a 4.4 Å resolution cryo-electron microscopy map of Schizosaccharomyces pombe Mediator in which conserved Mediator subunits are individually resolved. The essential Med14 subunit works as a central backbone that connects the Mediator head, middle and tail modules. Comparison with a 7.8 Å resolution cryo-electron microscopy map of a Mediator-RNA polymerase II holoenzyme reveals that changes in the structure of Med14 facilitate a large-scale Mediator rearrangement that is essential for holoenzyme formation. Our study suggests that access to different conformations and crosstalk between structural elements are essential for the Mediator regulation mechanism, and could explain the capacity of the complex to integrate multiple regulatory signals.

    2004-01-01

    In this note, recent results on the search for Gauge Mediated Supersymmetry Breaking (GMSB) and Anomaly Mediated Supersymmetry Breaking (AMSB) at the LEP and Tevatron colliders are summarized. We report on DOe's search for GMSB in di-photon events with large missing transverse energy and discuss the sensitivity of similar searches based on future Tevatron integrated luminosities. (orig.)

  3. An exponential decay model for mediation.

    Fritz, Matthew S

    2014-10-01

    Mediation analysis is often used to investigate mechanisms of change in prevention research. Results finding mediation are strengthened when longitudinal data are used because of the need for temporal precedence. Current longitudinal mediation models have focused mainly on linear change, but many variables in prevention change nonlinearly across time. The most common solution to nonlinearity is to add a quadratic term to the linear model, but this can lead to the use of the quadratic function to explain all nonlinearity, regardless of theory and the characteristics of the variables in the model. The current study describes the problems that arise when quadratic functions are used to describe all nonlinearity and how the use of nonlinear functions, such as exponential decay, address many of these problems. In addition, nonlinear models provide several advantages over polynomial models including usefulness of parameters, parsimony, and generalizability. The effects of using nonlinear functions for mediation analysis are then discussed and a nonlinear growth curve model for mediation is presented. An empirical example using data from a randomized intervention study is then provided to illustrate the estimation and interpretation of the model. Implications, limitations, and future directions are also discussed.

  4. Light mediators in dark matter direct detections

    Li, Tai; Miao, Sen; Zhou, Yu-Feng

    2015-01-01

    In an extended effective operator framework, we investigate in detail the effects of light mediators on the event spectra of dark matter (DM)-nucleus scatterings. The presence of light mediators changes the interpretation of the current experimental data, especially the determination of DM particle mass. We show by analytic and numerical illustrations that in general for all the operators relevant to spin-independent scatterings, the DM particle mass allowed by a given set of experimental data increases significantly when the mediator particle becomes lighter. For instance, in the case of CDMS-II-Si experiment, the allowed DM particle mass can reach ∼50 (100) GeV at 68% (90%) confidence level, which is much larger than ∼10 GeV in the case with contact interactions. The increase of DM particle mass saturates when the mediator mass is below O(10) MeV. The upper limits from other experiments such as SuperCDMS, CDMSlite, CDEX, XENON10/100, LUX, PandaX etc. all tend to be weaker toward high DM mass regions. In a combined analysis, we show that the presence of light mediators can partially relax the tension in the current results of CDMS-II-Si, SuperCDMS and LUX

  5. A default Bayesian hypothesis test for mediation.

    Nuijten, Michèle B; Wetzels, Ruud; Matzke, Dora; Dolan, Conor V; Wagenmakers, Eric-Jan

    2015-03-01

    In order to quantify the relationship between multiple variables, researchers often carry out a mediation analysis. In such an analysis, a mediator (e.g., knowledge of a healthy diet) transmits the effect from an independent variable (e.g., classroom instruction on a healthy diet) to a dependent variable (e.g., consumption of fruits and vegetables). Almost all mediation analyses in psychology use frequentist estimation and hypothesis-testing techniques. A recent exception is Yuan and MacKinnon (Psychological Methods, 14, 301-322, 2009), who outlined a Bayesian parameter estimation procedure for mediation analysis. Here we complete the Bayesian alternative to frequentist mediation analysis by specifying a default Bayesian hypothesis test based on the Jeffreys-Zellner-Siow approach. We further extend this default Bayesian test by allowing a comparison to directional or one-sided alternatives, using Markov chain Monte Carlo techniques implemented in JAGS. All Bayesian tests are implemented in the R package BayesMed (Nuijten, Wetzels, Matzke, Dolan, & Wagenmakers, 2014).

  6. The Mediator Complex and Lipid Metabolism.

    Zhang, Yi; Xiaoli; Zhao, Xiaoping; Yang, Fajun

    2013-03-01

    The precise control of gene expression is essential for all biological processes. In addition to DNA-binding transcription factors, numerous transcription cofactors contribute another layer of regulation of gene transcription in eukaryotic cells. One of such transcription cofactors is the highly conserved Mediator complex, which has multiple subunits and is involved in various biological processes through directly interacting with relevant transcription factors. Although the current understanding on the biological functions of Mediator remains incomplete, research in the past decade has revealed an important role of Mediator in regulating lipid metabolism. Such function of Mediator is dependent on specific transcription factors, including peroxisome proliferator-activated receptor-gamma (PPARγ) and sterol regulatory element-binding proteins (SREBPs), which represent the master regulators of lipid metabolism. The medical significance of these findings is apparent, as aberrant lipid metabolism is intimately linked to major human diseases, such as type 2 diabetes and cardiovascular disease. Here, we briefly review the functions and molecular mechanisms of Mediator in regulation of lipid metabolism.

  7. The mediating effects of self-esteem and delinquency on the relationship between family social capital and adolescents’ educational achievement

    Omolola Abiola Adedokun

    2008-07-01

    Full Text Available Using a nationally representative data of rural adolescent boys and girls in 10th grade through 12th grade, this study explored the mediating effects of self-esteem and delinquency on the educational achievement of rural adolescents. Structural equation modeling analyses reveal that the combination of self-esteem and delinquency completely mediates the influence of family social capital on educational achievement. The findings of the models make a compelling case that the impact of family processes on educational achievement is indirect rather than direct.

  8. MEDIATOR18 and MEDIATOR20 confer susceptibility to Fusarium oxysporum in Arabidopsis thaliana

    Stiller, Jiri; Davoine, Celine; Björklund, Stefan; Manners, John M.; Kazan, Kemal; Schenk, Peer M.

    2017-01-01

    The conserved protein complex known as Mediator conveys transcriptional signals by acting as an intermediary between transcription factors and RNA polymerase II. As a result, Mediator subunits play multiple roles in regulating developmental as well as abiotic and biotic stress pathways. In this report we identify the head domain subunits MEDIATOR18 and MEDIATOR20 as important susceptibility factors for Fusarium oxysporum infection in Arabidopsis thaliana. Mutants of MED18 and MED20 display down-regulation of genes associated with jasmonate signaling and biosynthesis while up-regulation of salicylic acid associated pathogenesis related genes and reactive oxygen producing and scavenging genes. We propose that MED18 and MED20 form a sub-domain within Mediator that controls the balance of salicylic acid and jasmonate associated defense pathways. PMID:28441405

    2011-12-01

    Full Text Available This session of the workshop was dedicated to alternative dispute resolutions (ADR, which consists of dispute resolution processes and techniques through which disagreeing parties come to an agreement without having to litigate. Despite historic resistance, over the years ADR has gained widespread acceptance among both the general public and the legal profession. In the discussion there was a specific emphasis on mediation and arbitration. Kathrin Nitschmann, a lawyer and mediator from Saarbruecken, Germany, talked about “Professionalisation in mediation”. In addition to participation aspects she determined both the risks and the perspectives of professionalization in mediation. Luigi Cominelli, Assistant Professor of Sociology of Law at the University of Milan, Italy, reported on “Regulating Mediation in the EU”. He described the history of regulating mediation in the EU as well as domestic regulations since the beginning of modern mediation movement in the western world since the 1970s. Claude Witz, a French civil law professor at the University of Saarland, Germany, referred to “His experience in arbitration.” After highlighting some aspects of his experience, he pointed out the importance of arbitration in international commercial disputes. Alec Stone Sweet, Leitner Professor of Law, Politics, and International Studies, Yale Law School, United States, was reporting on “Arbitration and judicialization.” Initially, he presented arbitration as a triadic dispute resolution and then focused on judizialization in arbitration. Sir David Edward, former Judge of the Court of Justice of the European Communities and Professor Emeritus of the School of Law of the University of Edinburgh, United Kingdom, spoke about “The view of an arbitrator.” While elaborating on multiple reasons for ADR, he honed focus on mediation and arbitration.

  11. Mediation Training for the Physician: Expanding the Communication Toolkit to Manage Conflict.

    Kayser, Joshua B

    2015-01-01

    Good communication is critical to the practice of medicine. This is particularly true when outcomes are unpredictable and/or patients lack the capacity to participate in medical decision making. Disputes may develop that cannot be addressed using basic communication skills. Conflict of this nature can burden patients, families, and medical staff and may result in increased suffering for all parties. Many physicians lack the necessary communication tools to handle difficult conversations. Training in bioethics mediation provides physicians with skills that can promote healing by empowering participants to engage in effective discourse and break down barriers to find common ground. Mediation training for physicians can expand their capacity to connect with patients and enhance their ability to identify potential conflict early on, in order to collaborate more effectively. Competency in the processes of negotiation and conflict resolution should therefore be seen as essential elements of medical training. Copyright 2015 The Journal of Clinical Ethics.

  12. Long-Term Effects of a Universal Family Intervention: Mediation Through Parent-Adolescent Conflict

    Jensen, M.; Wong, J.J.; Gonzales, N.A.; Dumka, L.E.; Millsap, R.; Coxe, S.

    2014-01-01

    Objective This randomized trial of a family-focused preventive intervention for Mexican American middle schoolers examined internalizing, externalizing, and substance use outcomes in late adolescence, five years after completing the intervention. Parent-adolescent conflict was tested as a mediator of these effects. The role of parent and adolescent acculturation in these pathways was also examined. Method 498 7th grade adolescents and their primary female caregivers were randomized to receive either a 9-week, multi-component intervention or a brief workshop control group. Assessments were conducted at pre-test, two year follow-up (9th grade), and five year follow-up (when most participants were in the 12th grade). Results The Bridges program significantly reduced mother-adolescent conflict measured in the 9th grade, with conflict mediating program effects on internalizing and externalizing symptoms, adolescent substance use, and diagnosed internalizing disorder in late adolescence. Mother and child acculturation were both significantly predictive of late adolescence outcomes. Contrary to hypotheses, neither mother nor child acculturation emerged as a significant predictor of mother-adolescent conflict, and the interaction of mother and adolescent acculturation was similarly not related to mother-adolescent conflict. Intervention effects were largely consistent across different levels of acculturation. Conclusions These findings provide support for the efficacy of family-focused intervention during early adolescence, both in reducing mental health problems and substance use in the long term, as well as in impacting parent-adolescent conflict processes that appear to play an important role in the development of later adjustment problems.

Efficient and fair conflict resolution in the electricity industry; Verbesserung der Konfliktloesungsinstrumente der VVII durch Mediation. Effiziente und faire Konfliktloesung in der Stromwirtschaft

    Neuenhahn, H.U. [Gesellschaft fuer Wirtschaftsmediation und Konfliktmangement e.V. (Germany)

    2001-09-10

    The author discusses the essential instruments for conflict management laid down in the VVII, the agreement of the industrial associations of the German electricity industry. The VVII is an agreement under civil law and defines the rules to be observed by the trading parties in connection with power transmission, TPA to networks and pricing policy in the competitive market. Analysing and criticising the experience so far with the existing instruments, the author suggests to adopt mediation as a new modality for conflict resolution, referring to available positive experience elsewhere. The parties actively and responsibly participate in the solution of their conflict satisfying their interests. The parties exclusively decide on the continuation and the result of the mediation procedure, and the arbiter does not act as a judge but as a mediator. (orig./CB)

  14. Practical guidance for conducting mediation analysis with multiple mediators using inverse odds ratio weighting.

    Nguyen, Quynh C; Osypuk, Theresa L; Schmidt, Nicole M; Glymour, M Maria; Tchetgen Tchetgen, Eric J

    2015-03-01

    Despite the recent flourishing of mediation analysis techniques, many modern approaches are difficult to implement or applicable to only a restricted range of regression models. This report provides practical guidance for implementing a new technique utilizing inverse odds ratio weighting (IORW) to estimate natural direct and indirect effects for mediation analyses. IORW takes advantage of the odds ratio's invariance property and condenses information on the odds ratio for the relationship between the exposure (treatment) and multiple mediators, conditional on covariates, by regressing exposure on mediators and covariates. The inverse of the covariate-adjusted exposure-mediator odds ratio association is used to weight the primary analytical regression of the outcome on treatment. The treatment coefficient in such a weighted regression estimates the natural direct effect of treatment on the outcome, and indirect effects are identified by subtracting direct effects from total effects. Weighting renders treatment and mediators independent, thereby deactivating indirect pathways of the mediators. This new mediation technique accommodates multiple discrete or continuous mediators. IORW is easily implemented and is appropriate for any standard regression model, including quantile regression and survival analysis. An empirical example is given using data from the Moving to Opportunity (1994-2002) experiment, testing whether neighborhood context mediated the effects of a housing voucher program on obesity.

    We revisit a special model of gauge mediated supersymmetry breaking, the “R-invariant direct gauge mediation.” We pay particular attention to whether the model is consistent with the minimal model of the μ-term, i.e., a simple mass term of the Higgs doublets in the superpotential. Although the incompatibility is highlighted in view of the current experimental constraints on the superparticle masses and the observed Higgs boson mass, the minimal μ-term can be consistent with the R-invariant gauge mediation model via a careful choice of model parameters. We derive an upper limit on the gluino mass from the observed Higgs boson mass. We also discuss whether the model can explain the 3σ excess of the Z+jets+E{sub T}{sup miss} events reported by the ATLAS collaboration.

  16. Sensemaking in Technology-Use Mediation

    2006-01-01

    of advanced CSCW technologies is basically a problem of sensemaking. We analyze how a group of “technology-use mediators” (Orlikowski et al. Org. Sci. (1995) 6(4), 423) in a large, multinational company adapted a groupware technology (a “virtual workspace”) to the local organizational context (and vice versa......) by modifying features of the technology, providing ongoing support for users, and promoting appropriate conventions of use. Our findings corroborate earlier research on technology-use mediation, which suggests that such mediators can exert considerable influence on how a particular technology...... will be established and used in an organization. However, we also find that the process of technology-use mediation is much more complex and indeterminate than prior research suggests. The reason being, we argue, that new, advanced CSCW technologies, such as “virtual workspaces” and other groupware applications...

  17. Gravity mediated supersymmetry breaking in six dimensions

    Falkowski, A.; Lee, H.M.; Luedeling, C.

    2005-04-01

    We study gravity mediated supersymmetry breaking in four-dimensional effective theories derived from six-dimensional brane-world supergravities. Using the Noether method we construct a locally supersymmetric action for a bulk-brane system consisting of the minimal six-dimensional supergravity coupled to vector and chiral multiplets located at four-dimensional branes. We compactify this system on T 2 /Z 2 and derive the four-dimensional effective supergravity. Most interestingly, sequestering of the matter living on different branes is not explicit in the tree-level Kaehler potential (but of course the action obtained from this Kaehler potential is consistent with higher dimensional locality). As a consequence, the features of gravity mediation are different than in five-dimensional models. We identify one scenario of moduli stabilization that yields positive gravity mediated soft scalar masses squared. (orig.)

  18. Can Job Control Ameliorate Work-family Conflict and Enhance Job Satisfaction among Chinese Registered Nurses? A Mediation Model

    Xiaotong Ding

    2018-04-01

    Full Text Available Background: Low job satisfaction is the most common cause of nurses' turnover and influences the quality of nursing service. Moreover, we have no idea regarding whether job control, as an individual factor, can play a role in the relationship. Objective: To explore the relationship between work-family conflict and job satisfaction among Chinese registered nurses and the mediating role of job control in this relationship. Methods: From August 2015 to November 2016, 487 Chinese registered nurses completed a survey. The study used work-family conflict scale, job control scale, job satisfaction scale, as well as general information. Multiple regression analysis was used to explore the independent factors of job satisfaction. Structural equation model was used to explore the mediating role of job control. Results: Work-family conflict was negatively correlated with job satisfaction (r ‑0.432, p<0.01. In addition, job control was positively related to job satisfaction (r 0.567, p<0.01. Work-family conflict and job control had significant predictive effects on job satisfaction. Job control partially mediated the relationship between work-family conflict and job satisfaction. Conclusion: Work-family conflict affected job satisfaction and job control was a mediator in this relationship among Chinese registered nurses. Job control could potentially improve nurses' job satisfaction.

  19. Mediator kinase module and human tumorigenesis.

    Clark, Alison D; Oldenbroek, Marieke; Boyer, Thomas G

    2015-01-01

    Mediator is a conserved multi-subunit signal processor through which regulatory informatiosn conveyed by gene-specific transcription factors is transduced to RNA Polymerase II (Pol II). In humans, MED13, MED12, CDK8 and Cyclin C (CycC) comprise a four-subunit "kinase" module that exists in variable association with a 26-subunit Mediator core. Genetic and biochemical studies have established the Mediator kinase module as a major ingress of developmental and oncogenic signaling through Mediator, and much of its function in signal-dependent gene regulation derives from its resident CDK8 kinase activity. For example, CDK8-targeted substrate phosphorylation impacts transcription factor half-life, Pol II activity and chromatin chemistry and functional status. Recent structural and biochemical studies have revealed a precise network of physical and functional subunit interactions required for proper kinase module activity. Accordingly, pathologic change in this activity through altered expression or mutation of constituent kinase module subunits can have profound consequences for altered signaling and tumor formation. Herein, we review the structural organization, biological function and oncogenic potential of the Mediator kinase module. We focus principally on tumor-associated alterations in kinase module subunits for which mechanistic relationships as opposed to strictly correlative associations are established. These considerations point to an emerging picture of the Mediator kinase module as an oncogenic unit, one in which pathogenic activation/deactivation through component change drives tumor formation through perturbation of signal-dependent gene regulation. It follows that therapeutic strategies to combat CDK8-driven tumors will involve targeted modulation of CDK8 activity or pharmacologic manipulation of dysregulated CDK8-dependent signaling pathways.

  20. Friends' cultural orientation as a mediator between familial ethnic socialization and ethnic identity among Mexican-origin adolescent girls.

    Kim, Peter Seung Yoo; Bámaca-Colbert, Mayra Y; Jian, Ni; Gonzales-Backen, Melinda A

    2017-04-01

    Research has indicated that ethnic identity protects ethnic minority youth on various indicators of adjustment, but there is a dearth of research pertaining to contextual influences on ethnic identity. Our study investigated how familial ethnic socialization and best friend's orientation toward Mexican culture influenced ethnic identity among Mexican-origin girls. Using a 3-wave longitudinal sample of 175 Mexican-origin adolescent girls (Mage = 13.75), the current study examined best friend's Mexican cultural orientation as a mediator between familial ethnic socialization and ethnic identity with structural equation modeling. Multigroup analyses were conducted to examine potential age and generational status differences within the model. Analyses revealed that familial ethnic socialization promoted ethnic identity exploration and resolution 3.5 years later and that this effect was mediated by best friend's Mexican cultural orientation. No significant differences were found across age or generational status groups. Our study highlights the contribution of peer context to ethnic identity and its role in the process by which familial ethnic socialization influences ethnic identity during adolescence.

  1. Extended tree-level gauge mediation

    Monaco, M.; Nardecchia, M.; Romanino, A.

    2011-01-01

    Tree-level gauge mediation (TGM) is a scenario of SUSY breaking in which the tree-level exchange of heavy (possibly GUT) vector fields generates flavor-universal sfermion masses. In this work we extend this framework to the case of E(6) that is the natural extension of the minimal case studied so...... if the gauge group does not contain SU(5). If SUSY breaking is mediated purely by the U(1) generator that commutes with SO(10) we obtain universal sfermion masses and thus can derive the CMSSM boundary conditions in a novel scenario....

  2. Barley Transformation Using Agrobacterium-Mediated Techniques

    Harwood, Wendy A.; Bartlett, Joanne G.; Alves, Silvia C.; Perry, Matthew; Smedley, Mark A.; Leyland, Nicola; Snape, John W.

    Methods for the transformation of barley using Agrobacterium-mediated techniques have been available for the past 10 years. Agrobacterium offers a number of advantages over biolistic-mediated techniques in terms of efficiency and the quality of the transformed plants produced. This chapter describes a simple system for the transformation of barley based on the infection of immature embryos with Agrobacterium tumefaciens followed by the selection of transgenic tissue on media containing the antibiotic hygromycin. The method can lead to the production of large numbers of fertile, independent transgenic lines. It is therefore ideal for studies of gene function in a cereal crop system.

  3. Family functioning mediates the association between parental depression and low self-esteem in adolescents.

    Krug, Susann; Wittchen, Hans-Ulrich; Lieb, Roselind; Beesdo-Baum, Katja; Knappe, Susanne

    2016-10-01

    The negative impact of parental depression on offsprings' development has been repeatedly documented. There is however little research on the potential pathways contributing to this association. The present study examined the relationship between parental depressive disorders, family functioning and adolescents' self-esteem. A community-based sample of 1040 participants aged 14-17 years and their parents was assessed including direct and indirect information on parental psychopathology based on the Munich-Composite International Diagnostic Interview (M-CIDI). Family functioning and youth self-esteem were assessed by self-report questionnaires using the McMaster Family Assessment Device (FAD) in parents and the "Aussagen-Liste zum Selbstwertgefühl" in adolescents. Findings from multiple regression analyses indicated positive associations between parental depressive disorders and dimensions of dysfunctional family functioning as well as between dysfunctional familial affective involvement and youth's positive self-esteem. The relationship between parental depression and self-esteem was partly mediated by familial affective involvement. Associations may be underestimated, since incidence for depressive disorders spans to the third decade of life. Consensus diagnoses for parental depressive disorders were based on direct and indirect information for maximum use of available data, neglecting familial load, chronicity of parental depressive disorders or comorbid conditions. Thus, specificity of the findings for the family transmission of depressive disorders remains yet to be determined. Findings contribute to understanding of the pathways on how parental depression impairs offsprings' view of themselves, and to consider family functioning as a possible target for preventive interventions.

  4. Support in work context and employees’ wellbeing: the mediation role of the work-family conflict

    Claúdia Sousa

    2018-03-01

    Full Text Available Changes in families and in the structure of the workforce have contributed to a change in traditional roles, leading to an increase of the number of men and women who simultaneously have family and work responsibilities. Because the workforce has different sources of support in the labor environment – organizational, supervisor, and coworker support – it becomes important to study the impacts that each of these sources of support has on workers’ general well-being and to understand whether the existent work-family conflict explains this relationship. Indeed, the present research aims to examine the relationship between perceived support and general well-being as well as the mediating effect of work-life conflict on this relationship. The data were collected from a company from the textile industry, composing a sample of 821 store operators. The results show that work-life conflict helps explain the relationship between support from the organization and coworkers and workers’ general well-being. However, supervisor support did not relate to work-family conflict. Based on the specific managerial characteristics of this company, some plausible explanations for these results are provided. Practical implications related to the results obtained are presented, in addition to the research limitations and suggestions for future research.

Work-family conflict was negatively correlated with job satisfaction (r ‑0.432, pjob control was positively related to job satisfaction (r 0.567, pjob control had significant predictive effects on job satisfaction. Job control partially mediated the relationship between work-family conflict and job satisfaction. Work-family conflict affected job satisfaction and job control was a mediator in this relationship among Chinese registered nurses. Job control could potentially improve nurses' job satisfaction.

    Background: Dysregulated stress neurocircuits, caused by genetic and/or environmental changes, underlie the development of many neuropsychiatric disorders. Corticotropin-releasing factor (CRF) is the major physiological activator of the hypothalamic-pituitary-adrenal (HPA) axis and conse-quently a primary regulator of the mammalian stress response. Together with its three family members, urocortins (UCNs) 1, 2, and 3, CRF integrates the neuroendocrine, autonomic, metabolic and behavioral responses to stress by activating its cognate receptors CRFR1 and CRFR2. Objective: Here we review the past and current state of the CRF/CRFR field, ranging from pharmacologi-cal studies to genetic mouse models and virus-mediated manipulations. Results: Although it is well established that CRF/CRFR1 signaling mediates aversive responses, includ-ing anxiety and depression-like behaviors, a number of recent studies have challenged this viewpoint by revealing anxiolytic and appetitive properties of specific CRF/CRFR1 circuits. In contrast, the UCN/CRFR2 system is less well understood and may possibly also exert divergent functions on physiol-ogy and behavior depending on the brain region, underlying circuit, and/or experienced stress conditions. Conclusion: A plethora of available genetic tools, including conventional and conditional mouse mutants targeting CRF system components, has greatly advanced our understanding about the endogenous mecha-nisms underlying HPA system regulation and CRF/UCN-related neuronal circuits involved in stress-related behaviors. Yet, the detailed pathways and molecular mechanisms by which the CRF/UCN-system translates negative or positive stimuli into the final, integrated biological response are not completely un-derstood. The utilization of future complementary methodologies, such as cell-type specific Cre-driver lines, viral and optogenetic tools will help to further dissect the function of genetically defined CRF/UCN neurocircuits in the context of

  7. Dynamic Allostery Mediated by a Conserved Tryptophan in the Tec Family Kinases.

    Full Text Available Bruton's tyrosine kinase (Btk is a Tec family non-receptor tyrosine kinase that plays a critical role in immune signaling and is associated with the immunological disorder X-linked agammaglobulinemia (XLA. Our previous findings showed that the Tec kinases are allosterically activated by the adjacent N-terminal linker. A single tryptophan residue in the N-terminal 17-residue linker mediates allosteric activation, and its mutation to alanine leads to the complete loss of activity. Guided by hydrogen/deuterium exchange mass spectrometry results, we have employed Molecular Dynamics simulations, Principal Component Analysis, Community Analysis and measures of node centrality to understand the details of how a single tryptophan mediates allostery in Btk. A specific tryptophan side chain rotamer promotes the functional dynamic allostery by inducing coordinated motions that spread across the kinase domain. Either a shift in the rotamer population, or a loss of the tryptophan side chain by mutation, drastically changes the coordinated motions and dynamically isolates catalytically important regions of the kinase domain. This work also identifies a new set of residues in the Btk kinase domain with high node centrality values indicating their importance in transmission of dynamics essential for kinase activation. Structurally, these node residues appear in both lobes of the kinase domain. In the N-lobe, high centrality residues wrap around the ATP binding pocket connecting previously described Catalytic-spine residues. In the C-lobe, two high centrality node residues connect the base of the R- and C-spines on the αF-helix. We suggest that the bridging residues that connect the catalytic and regulatory architecture within the kinase domain may be a crucial element in transmitting information about regulatory spine assembly to the catalytic machinery of the catalytic spine and active site.

    Mediator is a multiprotein complex that integrates the signals from transcription factors binding to the promoter and transmits them to achieve gene transcription. The subunits of Mediator complex reside in four modules: the head, middle, tail, and dissociable CDK8 kinase module (CKM). The head, middle, and tail modules form the core Mediator complex, and the association of CKM can modify the function of Mediator in transcription. Here, we show genetic and biochemical evidence that CKM-associated Mediator transmits auxin-dependent transcriptional repression in lateral root (LR) formation. The AUXIN/INDOLE 3-ACETIC ACID 14 (Aux/IAA14) transcriptional repressor inhibits the transcriptional activity of its binding partners AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19 by making a complex with the CKM-associated Mediator. In addition, TOPLESS (TPL), a transcriptional corepressor, forms a bridge between IAA14 and the CKM component MED13 through the physical interaction. ChIP assays show that auxin induces the dissociation of MED13 but not the tail module component MED25 from the ARF7 binding region upstream of its target gene. These findings indicate that auxin-induced degradation of IAA14 changes the module composition of Mediator interacting with ARF7 and ARF19 in the upstream region of their target genes involved in LR formation. We suggest that this regulation leads to a quick switch of signal transmission from ARFs to target gene expression in response to auxin.

  9. A classical regression framework for mediation analysis: fitting one model to estimate mediation effects.

    Saunders, Christina T; Blume, Jeffrey D

    Mediation analysis explores the degree to which an exposure's effect on an outcome is diverted through a mediating variable. We describe a classical regression framework for conducting mediation analyses in which estimates of causal mediation effects and their variance are obtained from the fit of a single regression model. The vector of changes in exposure pathway coefficients, which we named the essential mediation components (EMCs), is used to estimate standard causal mediation effects. Because these effects are often simple functions of the EMCs, an analytical expression for their model-based variance follows directly. Given this formula, it is instructive to revisit the performance of routinely used variance approximations (e.g., delta method and resampling methods). Requiring the fit of only one model reduces the computation time required for complex mediation analyses and permits the use of a rich suite of regression tools that are not easily implemented on a system of three equations, as would be required in the Baron-Kenny framework. Using data from the BRAIN-ICU study, we provide examples to illustrate the advantages of this framework and compare it with the existing approaches. © The Author 2017.

    Based on past research regarding the relationship between person-environment fit and work-family conflict (WFC), we examined the mediating effects of perceived organization/supervisor support on the relationship between person-organization/supervisor value congruence and WFC. A structural equation model was used to test three hypotheses using data collected from 637 workers in Taiwan. Person-organization value congruence regarding role boundaries was found to be positively correlated with employee perception of organizational support, resulting in reduced WFC. Person-supervisor value congruence regarding role boundaries also increased employee perception of organizational support, mediated by perceived supervisor support. Research and managerial implications are discussed.

  14. Individual and family factors associated with self-esteem in young people with epilepsy: A multiple mediation analysis.

    2017-01-01

    As young people experience added demands from living with epilepsy, which may lead to poor psychosocial adjustment, it is essential to examine mechanisms of change to provide practitioners with knowledge to develop effective interventions. The aim of this study was to examine individual and family-level factors - stress and illness perceptions, coping behaviors and family resilience - that promote or maintain young people's self-esteem. From November 2013 to August 2014, young people attending a neurology clinic in KK Women's and Children's Hospital, Singapore, participated in a cross-sectional survey (n=152; 13-16years old). Multiple mediation analyses were conducted to evaluate whether these variables mediated the relationship between illness severity (i.e., low, moderate, high) and self-esteem. Multiple mediation analyses demonstrated that illness severity had a direct effect on young people's self-esteem. Compared to those with moderate illness severity (reference group), young people with low severity had significantly higher self-esteem (c=3.42, pself-esteem through its effects on mediators, such as perceived stress, illness perceptions and family resilience (D 1 : Total ab=3.46, 95% CI 1.13, 5.71; D 2 : Total ab=-2.80, 95% CI -4.35, -1.30). However, young people's coping levels did not predict their self-esteem, when accounting for the effects of other variables. The continued presence of seizure occurrences is likely to place greater demands on young people and their families: in turn, increased stress and negative illness perceptions negatively affected family processes that promote resilience. As the mediating effect of these modifiable factors were above and beyond the contributions of illness characteristics and young people's levels of coping, this has implications for developing individual and family interventions aimed to support young people living with epilepsy.
