Linking Network Structure to Collaborative Governance

How do social networks differ between highly collaborative and less collaborative forms of governance? Drawing on a prior study that characterized the level of collaboration for three federal hydropower relicensing processes, we develop exponential random graph models of meeting attendance and participation networks. We find that the highly collaborative relicensing process had lower overall density and a propensity for relatively fewer and stronger interactions. Reciprocity is highest in the high-collaboration process, indicating that it is characterized by mutual interactions. In the low-collaboration process, patterns of connections between any three members of the network displayed a more unidirectional structure, suggesting asymmetrical interactions between active versus passive members of the network. By linking network structure to collaborative dynamics, this study helps elaborate potential mechanisms of successful collaboration.

CLASH-VLT: Environment-driven evolution of galaxies in thez= 0.209 cluster Abell 209

The analysis of galaxy properties and the relations among them and the environment, can be used to investigate the physical processes driving galaxy evolution. We study the cluster A209 by using the CLASH-VLT spectroscopic data combined with Subaru photometry, yielding to 1916 cluster members down to a stellar mass of 10^{8.6} Msun. We determine: i) the stellar mass function of star-forming and passive galaxies; ii) the intra-cluster light and its properties; iii) the orbits of low- and high-mass passive galaxies; and iv) the mass-size relation of ETGs. The stellar mass function of the star-forming galaxies does not depend on the environment, while the slope found for passive galaxies becomes flatter in the densest region. The color distribution of the intra-cluster light is consistent with the color of passive members. The analysis of the dynamical orbits shows that low-mass passive galaxies have tangential orbits, avoiding small pericenters around the BCG. The mass-size relation of low-mass passive ETGs is flatter than that of high mass galaxies, and its slope is consistent with that of field star-forming galaxies. Low-mass galaxies are also more compact within the scale radius of 0.65 Mpc. The ratio between stellar and number density profiles shows a mass segregation in the center. The comparative analysis of the stellar and total density profiles indicates that this effect is due to dynamical friction. Our results are consistent with a scenario in which the "environmental quenching" of low-mass galaxies is due to mechanisms such as harassment out to R200, starvation and ram-pressure stripping at smaller radii, as supported by the analysis of the mass function, of the dynamical orbits and of the mass-size relation of passive early-types in different regions. Our analyses support the idea that the intra-cluster light is formed through the tidal disruption of subgiant galaxies.

Styles of moderation in online health and support communities: An experimental comparison of their acceptance and effectiveness

Medical and social support communities depend very much on the active participation of their members. An active nurturing and moderation of online community activities is often necessary to overcome typical problems of community interaction, such as a lack of trust and active engagement. However, it is unclear what types of moderation and social control members do accept and which are effective. We study the acceptance and effectiveness of different moderation styles in two experimental scenario studies. Our results demonstrate that direct forms of control that provide members with incentives are not accepted and are regarded as ineffective, whereas more indirect forms that rely on relational interests and normative obligations are regarded to be more acceptable and effective. Furthermore, positive (rewarding) moderation styles are more effective than negative (punishing) styles. Members regard negative moderation styles as more effective for the avoidance of unacceptable (rule-breaking) behavior than for the stimulation of desirable (e.g., engaging) behavior. Acceptance and effectiveness of different moderation styles do not differ between active versus passive members.

How do German veterinarians use social networks? A study, using the example of the 'NOVICE' veterinary medicine network.

Objective: NOVICE (Network Of Veterinary ICT in Education, http://www.noviceproject.eu/), is a professional online social network for veterinarians, lecturers and students of veterinary medicine as well as for e-Learning advisers and others working in establishments that teach veterinary medicine. This study sets out to investigate to what extent German veterinarians, lecturers, students of veterinary medicine and e-Learning representatives would accept a specialist network, what requirements would have to be met by an online social network, how to use web 2.0 tools [21], [30] and what advantages a specialist network could offer. Methodology: The investigation was carried out by analysing data from the Elgg platform database as well as using Google Analytics. Annual focus group surveys and individual interviews were carried out in order to perform an analysis of acceptance among network users.Results: 1961 users from 73 different countries registered on the NOVICE site between 1 September 2010 and 21 March 2012. Germany represents the biggest user group, with 565 users (28.81%). During this period, most individual hits on the website came from Germany too. In total, 24.83% of all members are active, while 19.22% of German members participate actively. In terms of gender, there are significantly more female members than male members, both in the NOVICE network as a whole as well as in Germany. The most used web 2.0 tools are chat and email messaging services as well as writing wikis and contributing to forum discussions. The focus group surveys showed that respondents generally make use of other online communities too. Active members generally use more web 2.0 tools than in other networks, while passive members are generally more reluctant in all networks. All participants of the survey welcomed the idea of having a network specifically set up for the profession and believe that it could be very useful for veterinary medicine.Conclusions: The network and its membership figures developed very positively during the assessed time period. Until now, the focus of the content of contributions in NOVICE (Network of Veterinary ICT in Education) has been on veterinary medicine teaching supported by e-Learning. An increase in the number of members would, however, be beneficial in order to further develop the network so that valuable exchange of information and informal learning can also take place in other specialist areas of veterinary medicine.

An efficient optimal design methodology for non-linear multibody dynamics systems with application to vehicle occupant restraint systems

The need exists for robust and efficient optimal design methods for application to multibody systems, in which the components to be designed represent connections between large displacement, large rotation motions of the subsystems’ bodies. One specific application is occupant restraint systems, such as the Gunner Restraint System (GRS), in which both the vehicle and the gunner can undergo large relative and absolute motions under extreme driving or external threat conditions. In addition, the restraint/connection components can have amplitude-dependent, time-dependent, and timing-dependent behaviour, such as an active belt retractor. Current optimisation methodologies are ill suited for this problem, suffering from infeasibility, lack of robustness, and/or high computational expense. This paper presents an extension of topology optimisation techniques to consider multibody dynamics systems and to treat a much more open design space, which can include passive, active, and reactive structures/devices. The objective is to obtain an optimally combined structural and material system, considering the best use of passive, active and reactive members.

“What’s coming next?” Epistemic curiosity and lurking behavior in online communities

Prior research has repeatedly found that lurkers, the passive members of online communities, dominate such communities in terms of membership. Yet lurking in online communities reflects a phenomenon largely neglected by contemporary information systems theory and research. This study starts by reviewing existing literature on lurking behavior in online communities and identifies an unexplored opportunity related to the nature and origins of lurkers’ behavior, the individual propensity to de-lurk, and the dynamic interplay between lurking and de-lurking behavior. A theoretical process-based framework linking epistemic curiosity to lurking and de-lurking behavior in online communities is presented. This framework links prior academic work on epistemic curiosity as personality trait and emotional–motivational state to lurkers’ contribution behavior in online communities. The article concludes by proposing that the psychology of curiosity in general holds great promise for research on online communities in information systems.

Sharing as a form of anti‐consumption? An examination of toy library users

Abstract While the literature on anti‐consumption is rich and growing, there is still a lack of understanding among consumer researchers regarding why consumers choose to avoid consumption. This study seeks to extend the literature by exploring whether a group of consumers who reduce consumption through choosing to share rather than own are motivated by anti‐consumption reasons. The authors use quantitative data from 397 toy library members to explore why members choose to participate in this form of sharing. The study reveals four groups – Socialites, Market Avoiders, Quiet Anti‐Consumers and Passive Members. The Socialites enjoy the social benefits of active participation in their library. The Market Avoiders also perceived social and community benefits, are interested in sharing and are the least materialistic of the groups. The Quiet Anti‐Consumers feel a sense of belonging to their toy library and hold strong anti‐consumption, frugality and sharing values. The Passive Members are not socially involved, nor did they hold strong anti‐consumption values. Thus, the authors find evidence that sharing may be one possible alternative market structure that may be adopted by anti‐consumption consumers. Copyright © 2010 John Wiley & Sons, Ltd.

Amazons for Garibaldi: women warriors and the making of the hero of two worlds

This article analyses the place and meaning of female heroism in the process of the making of modern Italy. Beginning with Garibaldi's first wife Anita in Brazil, a great number of women all over the world were attracted to Garibaldi and his movement. Theirs was a sentimental and political engagement, which in some cases turned them into real soldiers, like those who joined the ranks of Garibaldi's troops. Whereas until 1860 the Garibaldinian volunteer was not understood as an exclusively male category, this changed around that key year, both in reality and in the collective imagination of the Risorgimento. Women were denied the right to be soldiers in Garibaldi's legendary Thousand. Subsequently, stories of militant women like Anita Garibaldi were softened in the foundation fictions that narrate the birth of Italy, turning women into passive members of the Italian nation. This change is analysed in depth by focusing on the emblematic case of Esperance von Schwartz, one of Garibaldi's biographers, and for a time, one of his female companions in arms.

Microbial diversity in biofilm infections of the urinary tract with the use of sonication techniques: Table 1

Infections of the urinary tract account for >40% of nosocomial infections; most of these are infections in catheterized patients. Bacterial colonization of the urinary tract and catheters causes not only the particular infection but also a number of complications, for example blockage of catheters with crystallic deposits of bacterial origin, generation of gravels and pyelonephritis. Infections of urinary catheters are only rarely single-species infections. The longer a patient is catheterized, the higher the diversity of biofilm microbial communities. The aims of this study were to investigate the microbial diversity on the catheters and to compare the ability to form biofilm among isolated microbial species. The next aim was to discriminate particular causative agents of infections of the urinary tract and their importance as biofilm formers in the microbial community on the urinary catheter. We examined catheters from 535 patients and isolated 1555 strains of microorganisms. Most of the catheters were infected by three or more microorganisms; only 12.5% showed monomicrobial infection. Among the microorganisms isolated from the urinary catheters, there were significant differences in biofilm-forming ability, and we therefore conclude that some microbial species have greater potential to cause a biofilm-based infection, whereas others can be only passive members of the biofilm community.

Multi-wavelength study of XMMU J2235.3-2557: the most massive galaxy cluster at z > 1

<i>Context. <i/>The galaxy cluster XMMU J2235.3-2557 (hereafter XMM2235), spectroscopically confirmed at , is one of the most distant X-ray selected galaxy clusters. It has been at the center of a multi-wavelength observing campaign with ground and space facilities.<i>Aims. <i/>We characterize the galaxy populations of passive members, the thermodynamical properties and metal abundance of the hot gas, and the total mass of the system using imaging data with HST/ACS (<i>i<i/><sub>775<sub/> and <i>z<i/><sub>850<sub/> bands) and VLT/ISAAC (<i>J<i/> and <i>K<i/><sub>S<sub/> bands), extensive spectroscopic data obtained with VLT/FORS2, and deep (196 ks) <i>Chandra <i/>observations. <i>Methods. <i/><i>Chandra <i/>data allow temperature and metallicity to be measured with good accuracy and the X-ray surface brightness profile to be traced out to 1´ (or 500 kpc), thus allowing the mass to be reliably estimated. Out of a total sample of 34 spectroscopically confirmed cluster members, we selected 16 passive galaxies (without detectable [OII]) within the central 2´ (or 1 Mpc) with ACS coverage, and inferred star formation histories for subsamples of galaxies inside and outside the core by modeling their spectro-photometric data with spectral synthesis models.<i>Results. <i/><i>Chandra <i/>data show a regular elongated morphology, closely resembling the distribution of core galaxies, with a significant cool core. We measure a global X-ray temperature of <i>kT<i/> = keV (68% confidence), which we find to be robust against several systematics involved in the X-ray spectral analysis. By detecting the rest frame 6.7 keV Iron K line in the <i>Chandra <i/> spectrum, we measure a metallicity <i>Z<i/> = . In the likely hypothesis of hydrostatic equilibrium, we obtain a total mass of (<1 Mpc)= (5.9<i>±<i/>1.3) 10<sup>14<sup/> . By modeling both the composite spectral energy distributions and spectra of the passive galaxies in and outside the core, we find a strong mean age radial gradient. Core galaxies, with stellar masses in excess of 10<sup>11<sup/> , appear to have formed at an earlier epoch with a relatively short star formation phase (), whereas passive galaxies outside the core show spectral signatures suggesting a prolonged star formation phase to redshifts as low as <i>z<i/> <i>≈<i/> 2. <i>Conclusions. <i/>Overall, our analysis implies that XMM2235 is the hottest and most massive bona-fide cluster discovered to date at , with a baryonic content, both its galaxy population and intracluster gas, in a significantly advanced evolutionary stage at 1/3 of the current age of the Universe.

Schools of democracy? Disentangling the relationship between civic participation and political action in 17 European countries

AbstractSince Tocqueville's seminal writings, voluntary associations have been proclaimed to be schools of democracy. According to this claim, which regained popularity during the 1990s, involvement in voluntary associations stimulates political action. By participating in these associations, members are socialised to become politically active. Supposedly, having face‐to‐face contact with other members induces civic mindedness – the propensity to think and care more about the wider world. Participating in shared activities, organising meetings and events, and cooperating with other members are claimed to induce civic skills and political efficacy. Over the years, many authors have elaborated on these ideas. This article offers a systematic examination of the neo‐Tocquevillian approach, putting the theoretical ideas to an empirical test. It offers a critical overview of the literature on the beneficial role of voluntary associations and dissects it into five testable claims. Subsequently, these claims are tested by cross‐sectional, hierarchical analyses of 17 European countries. The authors conclude that the neo‐Tocquevillian theory faces serious lack of empirical support. In line with the expectations, they find a strong, positive correlation between associational involvement and political action. Moreover, this correlation is positive in all countries under study. However, more informative hypotheses on this correlation are falsified. First, the correlation is stronger for interest and activist organisations than for leisure organisations. Second, passive (or ‘checkbook’) members show much higher levels of political action than non‐involved, whereas the additional effects of active participation are marginal. Third, the correlation between associational involvement and political action is not explained by civic skills and civic mindedness. In sum, the authors find no evidence for a direct, causal relation between associational involvement and political action. The socialisation mechanism plays a marginal role at best. Rather, this article's findings imply that selection effects account for a large part of the correlation between associational involvement and political action. The conclusion reached therefore is that voluntary associations are not the schools of democracy they are proclaimed to be, but rather pools of democracy.

Robustness of base‐isolated high‐rise buildings under code‐specified ground motions

AbstractThe robustness of base‐isolated high‐rise buildings is investigated under code‐specified ground motions. Friction‐type bearings are often used in base‐isolated high‐rise buildings to make the natural period of those buildings much longer. While additional damping can be incorporated into every story in passive controlled structures with inter‐story type passive members, that can be incorporated into the base‐isolation story only in the base‐isolated building. This fact leads to the property that, as the number of stories of the building becomes larger, the damping ratio reduces. This characteristic may cause some issues in the evaluation of robustness of base‐isolated high‐rise buildings. The purpose of this paper is to reveal the robustness of base‐isolated high‐rise buildings. A kind of inverse problem for the target drift in the base‐isolation story is formulated in order to determine the required quantity of additional viscous damping. It is demonstrated numerically that, as the base‐isolated building becomes taller, the damping ratio becomes smaller and the ratio of the friction‐type bearings in the total damping becomes larger. This may lead to the conclusion that base‐isolated high‐rise buildings have smaller robustness than base‐isolated low‐rise buildings. Copyright © 2007 John Wiley &amp; Sons, Ltd.

Origins of Social Capital: Socialization and Institutionalization Approaches Compared

How is social capital generated and sustained? In Putnam's micro-oriented socialization perspective, the main source is face-to-face interaction between members of voluntary organizations. This has so far met little empirical support. Consequently, macro-oriented scholars have concluded that organizations are unimportant to social capital formation. We argue that voluntary organizations do play a pivotal role, not as socialization agents, but as institutions within which social capital is embedded. Using European Social Survey data, we analyse the antecedents of social capital both at the individual and regional level. We find that members are more trusting than non-members, but active members are no more trusting than passive members. Furthermore, regional effects are much stronger than individual effects. Regions with high social capital are characterized by broad participation patterns and visible, politically active organizations. Based on these findings, we put forward an alternative institutional account of how organizations create and sustain social capital. Strong and visible voluntary organizations demonstrate the utility and rationality of collective action and provide individuals with a democratic infrastructure, which can be activated when needed. We support this by showing that a positive perception of the democratic value of organizations is strongly related to trust, while personal, time-intensive involvement has no explanatory power.

Analysis of the Spanish-speaking mailing list RADIOLOGIA

The objective of this study was to analyse the mailing list RADIOLOGIA during its first 5 years of operation (from 1998 to 2003). A survey questionnaire was sent to evaluate the characteristics of subscribers and to score (from 0 to 9) the functionality, usefulness and quality of the mailing list. All messages sent to the list during the evaluated period were classified and quantified. A social network analysis was performed from all messages replied to during 2001 and 2002 with the option “reply to” included in the subject. One hundred and forty (36.8%) responses were collected from 380 subscribers, mainly radiologists (90.0%). 80% of responders were located in Spain, 16% in Latin America, and 4% in other places. The obtained scores (mean ± standard deviation) were: functionality 7.4 ± 1.3; usefulness 7.0 ± 1.4; and quality of e-mail contents 6.0 ± 1.4. During the evaluated period 2700 e-mail messages were sent to the list, with a monthly distribution of 44.3 ± 26.0. The list functioning has been based on an active minority of subscribers that provided information and responses to the rest of the subscribers, a ring of active members that participated in discussions, and about 50% of passive members.

Relative Resistance Chemical Sensors Built on Microhotplate Platforms

AbstractThe selectivity, sensitivity, and speed of metal oxide conductometric chemical sensors can be improved by integrating them onto micromachined, thermally-controlled platforms (i.e., microhotplates). The improvements largely arise from the richness of signal inherent in arrays of multiple sensing materials and the ability to rapidly pulse and collect data at multiple temperatures. Unfortunately, like their macroscopic counterparts, these sensors can suffer from a lack of repeatability from sample-to-sample and even run-to-run. Here we report on a method to reduce signal drift and increase repeatability that is easily integrated with microhotplate chemical sensors. The method involves passivating one of a pair of identically-formed sensors by coating it with a highly electrically resistive and chemically impermeable film. Relative resistance measurements between the active and passive members of a pair then provide a signal that is reasonably constant over time despite electrical, thermal and gas flow rate fluctuations. Common modes of signal drift, such as microstructural changes within the sensing film, are also removed. The method is demonstrated using SnO2 and TiO2 microhotplate gas sensors, with a thin Al2O3 film forming the passivation layer. It is shown that methanol and acetone at concentrations of 1 µmol/mol, and possibly lower, are sensed with high reproducibility.

Response to Review of El derecho a la participación infantil de niñas, niños y adolescentes en situación de riesgo: menores no acompañados, niños y niñas afectados por conflictos armados y trabajadores infantiles [The Participation Rights of Children and Adolescents at Risk: Unaccompanied Minors, Children Affected by Armed Conflicts and Child Workers

693 Children, Youth and Environments Vol. 17 No. 2 (2007) ISSN: 1546-2250 Response to Review of El derecho a la participación infantil de niñas, niños y adolescentes en situación de riesgo: menores no acompañados, niños y niñas afectados por conflictos armados y trabajadores infantiles [The Participation Rights of Children and Adolescents at Risk: Unaccompanied Minors, Children Affected by Armed Conflicts and Child Workers] Raquel González Juárez Save the Children Spain Citation: González Juárez, Raquel. (2007). "Response to Review ofEl derecho a la participación infantil de niñas, niños y adolescentes en situación de riesgo: menores no acompañados, niños y niñas afectados por conflictos armados y trabajadores infantiles [The Participation Rights of Children and Adolescents at Risk: Unaccompanied Minors, Children Affected by Armed Conflicts and Child Workers]." Children, Youth and Environments 17 (2). Children and young people often represent over 40 percent of the societies in which they live, yet they have traditionally been excluded from decision-making all over the world. In general, children and adolescents are usually considered as passive members of society, without sufficient initiative and maturity to exercise their right to expression. However, their right of participation is clearly present in several articles in the UN Convention on the Rights of the Child (CRC). Articles 12 and 17 recognize that children have the right to freedom of expression, to form and join associations and to seek and receive appropriate information. The CRC therefore ensures that children have their place in civil society, along with opportunities to contribute, exchange ideas with other social players and be consulted about matters that concern them. Participating is not only expressing their opinion and asking; it involves being responsible, being aware, and getting involved. Save the Children works closely to foster child participation because: 694  Children can shape their own future rather than simply being beneficiaries of adult intervention.  Young people who have learned how to influence decisionmakers will be more confident as adults and may use these skills to improve their societies in the future.  Public policies on children’s issues are more effective when children are involved in the decision-making process. At Save the Children, child participation is a transversal aspect to be considered in all actions and programs aimed at children. Their participation has to be effective and seen as an ongoing process where beyond expressing their views, they are actively involved in the decision making. Yet, not only children have to be aware of their right to participation, but as adults, we have to be consistently committed to the participation of the youngest members of society. It is clearly not a simple process, but we cannot become discouraged from short-term results. This book contains the papers and conclusions of the working parties at the training workshop and seminar held in Madrid in May and June. The seminar considered the participation of children and adolescents at risk, specifically those that live in armed conflict situations, or are unaccompanied minors or child workers. We listened to the accounts of Ariel Zapana, an Argentinean child worker; Ioannis Padilla, a former child worker from Peru; Zoraida Ávarez and Beatriz Retamosa, students from Miguel Delibes High School in Madrid; Daniel Asante, an unaccompanied minor; and Sanja Kuljanin, who described what it was like to be an adolescent during the war in the former Yugoslavia. The seminar and workshops featured specialists from around the world (e.g., Argentina, Brussels, Spain, India, Peru, Sierra Leona, Sudan) who discussed their experience with child participation. A series of experts also provided us with useful tools for the effective diagnosis, assessment and application of those rights in cooperation projects for social inclusion and development. In addition, child participation was fostered with the presence of children and adolescents from different countries (e.g., Bosnia-Herzegovina, Peru, Morocco, Ghana and Spain) who told their stories and put 695 forward suggestions about what child participation should involve. In this book, we have reproduced in full the stories they told to us. In short, the training workshop and seminar, funded by the Madrid City Council, was an opportunity to bring various agents...

DANISH PARTY MEMBERS: PLUGGED OR UNPLUGGED?

Danish parties have adopted new information and communication technologies (ICT) and thereby introduced new online party activities facilitated by these new technologies. However, the application as of 2000–01, the time of the party member survey applied here, is still limited and the online participation of party members is not substantially changing the character of party member participation. However, even though limited the application of ICT does make a difference. Most members who are active online are also active offline. Hence, party members attending traditionally party meetings – in particular officeholders – participate more online than other members. But some otherwise passive party members are mobilised by activities facilitated by ICTs. Hence, the application of ICT has an impact on the amount of party activity. Furthermore, the representativeness of party member activity is affected by the application of ICTs. When compared to voters and party members in general, the age representativeness is ameliorated, whereas the education and gender representativeness are exacerbated. In sum, even though limited, the application of ICT within Danish parties has an impact on the character of party member participation.

Galaxy Cluster Assembly at z = 0.37

We present X-ray and spectroscopic confirmation of a cluster assembling from multiple, distinct galaxy groups at z = 0.371. Initially detected in the Las Campanas Distant Cluster Survey, the structure contains at least four X-ray-detected groups that lie within a maximum projected separation of 4 Mpc and within Δv = 550 km s-1 of one another. Using Chandra imaging and wide-field optical spectroscopy, we show that the individual groups lie on the local σ-T relation and derive a total mass of M ≥ 5 × 1014 M☉ for the entire structure. We demonstrate that the groups are gravitationally bound to one another and will merge into a single cluster with about one-third or more the mass of Coma. We also find that although the cluster is in the process of forming, the individual groups already have a higher fraction of passive members than the field. This result indicates that galaxy evolution on group scales is key to developing the early-type galaxies that dominate the cluster population by z ~ 0.

Family Holidays: A Research Review and Application to New Zealand

Holidays with children have largely been marginalised in research that examines leisure travel. This paper is a critical review of the available literature and presents a summary of themes relevant for the study of family holidays. Most tourism work is market-driven and from an adult perspective, with children treated as passive members of the family. Neglected areas include the social and cultural dimensions of the family holiday experience, such as social interactions and relationships, and the tangible and intangible benefits of holidays for family members. This discussion is contextualised within the current trends and issues relating to families in New Zealand. A research agenda is proposed that seeks to address the gaps in the tourism and travel literature, and particularly the need to lend a voice to children themselves, and recognise the experiences of all family members.

Regulatory actions of the A-kinase anchoring protein Yotiao on a heart potassium channel downstream of PKA phosphorylation

A-kinase anchoring proteins (AKAPs) are thought to be passive members of protein complexes that coordinate the association of cAMP-dependent protein kinase A (PKA) with cellular substrates to facilitate targeted PKA protein phosphorylation. I(Ks), the slow heart potassium current, is carried by the I(Ks) potassium channel, a substrate for PKA phosphorylation in response to sympathetic nerve stimulation, is a macromolecular complex that includes the KCNQ1 alpha subunit, the KCNE1 regulatory subunit, and the AKAP Yotiao. Disruption of this regulation by mutation in the long QT syndrome is associated with elevated risk of sudden death. Here, we have studied the effects of the AKAP Yotiao on the function of the I(Ks) channel that had been mutated to simulate channel phosphorylation, and we report direct AKAP-mediated alteration of channel function distinct from its role in the coordination of channel phosphorylation by PKA. These data reveal previously undescribed actions of Yotiao that occur subsequent to channel phosphorylation and provide evidence that this adaptor protein also may serve as an effector in regulating this important ion channel.
