[source] Adolescent Perceptions of Conflict in Interdependent and Disengaged FriendshipsJOURNAL OF RESEARCH ON ADOLESCENCE, Issue 3 2002Shmuel Shulman Interdependent and disengaged friendships in a middle-class sample of suburban Israeli adolescents were examined for differences in reports of conflict behavior. A total of 194 (100 females, and 94 males) close, reciprocal friends participated in a joint problem-solving task used to categorize friendships. Interdependent friends balanced closeness and individuality by cooperating on the task, whereas disengaged friends emphasized individuality by working independently on the task. In separate interviews, these friends recounted their most important conflict from the previous week. Older adolescents (M= 17.4 years) reported more conflicts over private disrespect than did younger adolescents (M= 12.7 years), whereas younger adolescents reported more conflicts over public disrespect and undependability than did older adolescents. Differences between friendship types in conflict initiation, negative affect, and relationship impact were found among older adolescents but not younger adolescents; differences in conflict resolutions were found in both age groups. In contrast to disengaged friends, interdependent friends were better able to manage conflicts in a manner that emphasized relationship harmony over individual gain. [source] Overload-induced skeletal muscle extracellular matrix remodelling and myofibre growth in mice lacking IL-6ACTA PHYSIOLOGICA, Issue 4 2009J. P. White Abstract Aim:, Overloading healthy skeletal muscle produces myofibre hypertrophy and extracellular matrix remodelling, and these processes are thought to be interdependent for producing muscle growth. Inflammatory cytokine interleukin-6 (IL-6) gene expression is induced in overloaded skeletal muscle, and the loss of this IL-6 induction can attenuate the hypertrophic response to overload (OV). Although the OV induction of IL-6 in skeletal muscle may be an important regulator of inflammatory processes and satellite cell proliferation, less is known about its role in the regulation of extracellular matrix remodelling. The purpose of the current study was to examine if OV-induced extracellular matrix remodelling, muscle growth, and associated gene expression were altered in mice that lack IL-6, when compared with wild-type mice. Methods:, Male C57/BL6 (WT) and C57/BL6 × IL-6,/, (IL-6,/,) mice (10 weeks of age) were assigned to either a sham control or synergist ablation OV treatments for 3, 21 or 56 days. Result:, Plantaris muscle mass increased 59% in WT and 116% in IL-6,/, mice after 21 day OV. Myofibre CSA was also increased by 21 day OV in both WT and IL-6,/, mice. OV induced a twofold greater increase in the volume of non-contractile tissue in IL-6,/, muscle compared to WT. OV also induced a significantly greater accumulation of hydroxyproline and procollagen-1 mRNA in IL-6,/, muscle, when compared with WT muscle after 21 day OV. Transforming growth factor-, and insulin-like growth factor-1 mRNA expression were also induced to a greater extent in IL-6,/, muscle when compared with WT muscle after 21 day OV. There was no effect of IL-6 loss on the induction of myogenin, and cyclin D1 mRNA expression after 3 day OV. However, MyoD mRNA expression in 3 day OV IL-6,/, muscle was attenuated when compared with WT OV mice. Conclusion:, IL-6 appears to be necessary for the normal regulation of extracellular matrix remodelling during OV-induced growth. [source] Managing Interdependence: The Effects of Outsourcing Structure on the Performance of Complex Projects,DECISION SCIENCES, Issue 1 2008Pamsy P. Hui ABSTRACT The outsourcing of complex activities has become a common organizational practice. Yet very little research has focused on the implications of how these activities are divided up among outsourcing partners. Drawing on structural contingency theory, we argue that: (1) because activities within stages of complex projects are highly interdependent, outsourcing structures where owner firms do not maintain high levels of dominance over the activities that are performed will pose control and coordination challenges, leading to poor project performance; (2) the adverse effects of poorly structured outsourcing arrangements will spill over to subsequent project stages when activities are interdependent across project stages; and (3) dividing activities among large numbers of contractors or distributing work evenly among contractors exacerbates coordination and control problems further contributing to poor project performance. Our empirical analysis of 323 capital facility construction projects supports our predictions. Overall, these results provide strong evidence that some outsourcing structures are more costly than others and that because of the nature of complex projects the detrimental effects of poorly structured outsourcing are often not completely observable at the time activities are completed. We discuss the implications of our findings for capital construction and for outsourcing more generally. [source] Role of VEGF and tissue hypoxia in patterning of neural and vascular cells recruited to the embryonic heartDEVELOPMENTAL DYNAMICS, Issue 11 2009Hongbin Liu Abstract We hypothesized that oxygen gradients and hypoxia-responsive signaling may play a role in the patterning of neural or vascular cells recruited to the developing heart. Endothelial progenitor and neural cells are recruited to and form branched structures adjacent to the relatively hypoxic outflow tract (OFT) myocardium from stages 27,32 (ED6.5,7.5) of chick development. As determined by whole mount confocal microscopy, the neural and vascular structures were not anatomically associated. Adenoviral delivery of a VEGF trap dramatically affected the remodeling of the vascular plexus into a coronary tree while neuronal branching was normal. Both neuronal and vascular branching was diminished in the hearts of embryos incubated under hyperoxic conditions. Quantitative analysis of the vascular defects using our recently developed VESGEN program demonstrated reduced small vessel branching and increased vessel diameters. We propose that vascular and neural patterning in the developing heart share dependence on tissue oxygen gradients but are not interdependent.

[source] Rats selectively bred for low levels of 50 kHz ultrasonic vocalizations exhibit alterations in early social motivationDEVELOPMENTAL PSYCHOBIOLOGY, Issue 4 2008K.M. Harmon Abstract In rats, the rates of 50 kHz ultrasonic vocalizations (USVs) can be used as a selective breeding phenotype and variations in this phenotype can be an indicator of affective states. The 50 kHz USV is elicited by rewarding stimuli (e.g., food, sexual behavior) and therefore can express a positive affective state. Conversely, the 22 kHz USV is elicited by aversive stimuli (e.g., presence of a predator, social defeat) indicating a negative affective state. In the present study, we tested the effect of selectively breeding for 50 kHz USVs on a variety of maternal social/emotional behaviors in young rat pups (PND 10-12). These measures consisted of an assessment of isolation calls and conditioned odor preference paradigm. Results indicate that animals selected for low levels of 50 kHz USVs show the greatest alterations in social behaviors compared to the control animals. The low line animals had an increase in isolation calls tested during place preference conditioning and a decrease in 50 kHz ultrasonic calls in all conditions. These same low line animals failed to show a typical preference for a maternally-associated odor during the place preference test. The different social behaviors of the high line animals did not consistently vary from those of the control group. These results have important implications for the study of genetic and epigenetic mechanisms underlying emotional states, and possibly contribute to the research underlying the emotional changes in developmental disorders such as autistic spectrum disorder by providing a novel animal model that displays communication deficits that are interdependent with significant social behavioral impairments. © 2008 Wiley Periodicals, Inc.

In obligate symbioses with horizontal transmission, the population dynamics of the partner organisms are highly interdependent. Host population size limits symbiont number, and distribution of partners is restricted by the presence and thus dispersal abilities of their respective partner. The Crematogaster decamera,Macaranga hypoleuca ant,plant symbiosis is obligate for both partners. Host survival depends on colonisation by its ant partner while foundress queens require hosts for colony establishment. 2. An experimental approach and population genetic analyses were combined to estimate dispersal distances of foundresses in their natural habitat in a Bornean primary rainforest. 3. Colonisation frequency was significantly negatively correlated with distance to potential reproductive colonies. Results were similar for seedlings at natural densities as well as for seedlings brought out in the area experimentally. Population genetic analysis revealed significant population differentiation with an FST of 0.041 among foundresses (n = 157) located at maximum 2280 m apart. In genetic spatial autocorrelation, genotypes of foundresses were significantly more similar than expected at random below 550 m and less similar above 620 m. Direct estimation of dispersal distances by pedigree analysis yielded an average dispersal distance of 468 m (maximum 1103 m). 4. For ants that disperse on the wing, genetic differentiation at such small spatial scales is unusual. The specific nesting requirements of the queens and the necessity for queens to find a host quickly could lead to colonisation of the first suitable seedling encountered, promoting short dispersal distances. Nonetheless, dispersal distances of C. decamera queens may vary with habitat or host spatial distribution. [source] A cross-system synthesis of consumer and nutrient resource control on producer biomassECOLOGY LETTERS, Issue 7 2008Daniel S. Gruner Abstract Nutrient availability and herbivory control the biomass of primary producer communities to varying degrees across ecosystems. Ecological theory, individual experiments in many different systems, and system-specific quantitative reviews have suggested that (i) bottom,up control is pervasive but top,down control is more influential in aquatic habitats relative to terrestrial systems and (ii) bottom,up and top,down forces are interdependent, with statistical interactions that synergize or dampen relative influences on producer biomass. We used simple dynamic models to review ecological mechanisms that generate independent vs. interactive responses of community-level biomass. We calibrated these mechanistic predictions with the metrics of factorial meta-analysis and tested their prevalence across freshwater, marine and terrestrial ecosystems with a comprehensive meta-analysis of 191 factorial manipulations of herbivores and nutrients. Our analysis showed that producer community biomass increased with fertilization across all systems, although increases were greatest in freshwater habitats. Herbivore removal generally increased producer biomass in both freshwater and marine systems, but effects were inconsistent on land. With the exception of marine temperate rocky reef systems that showed positive synergism of nutrient enrichment and herbivore removal, experimental studies showed limited support for statistical interactions between nutrient and herbivory treatments on producer biomass. Top,down control of herbivores, compensatory behaviour of multiple herbivore guilds, spatial and temporal heterogeneity of interactions, and herbivore-mediated nutrient recycling may lower the probability of consistent interactive effects on producer biomass. Continuing studies should expand the temporal and spatial scales of experiments, particularly in understudied terrestrial systems; broaden factorial designs to manipulate independently multiple producer resources (e.g. nitrogen, phosphorus, light), multiple herbivore taxa or guilds (e.g. vertebrates and invertebrates) and multiple trophic levels; and , in addition to measuring producer biomass , assess the responses of species diversity, community composition and nutrient status. [source] Precautionary Bidding in AuctionsECONOMETRICA, Issue 1 2004Péter Esö We analyze bidding behavior in auctions when risk-averse buyers bid for a good whose value is risky. We show that when the risk in the valuations increases, DARA bidders will reduce their bids by more than the appropriate increase in the risk premium. Ceteris paribus, buyers will be better off bidding for a more risky object in first price, second price, and English auctions with affiliated common (interdependent) values. This "precautionary bidding" effect arises because the expected marginal utility of income increases with risk, so buyers are reluctant to bid so highly. We also show that precautionary bidding behavior can make DARA bidders prefer bidding in a common values setting to bidding in a private values one when risk-neutral or CARA bidders would be indifferent. Thus the potential for a "winner's curse" can be a blessing for rational DARA bidders. [source] Personality profiles of cultures: Patterns of ethos,EUROPEAN JOURNAL OF PERSONALITY, Issue 3 2009Robert R. McCrae Abstract Culture and the human mind are deeply interdependent, because they co-evolved. Personality traits were a preexisting feature of the primate mind and must have left an imprint on forms of culture. Trait taxonomies can structure ethnographies, by specifying institutions that reflect the operation of traits. Facets of ethos can be assessed by expert ratings or objective indicators. Ratings of ethos in Japan and the US were reliable and yielded plausible descriptions of culture. However, measures of ethos based on the analysis of stories were not meaningfully correlated with aggregate personality traits or national character stereotypes. Profiles of ethos may provide another axis that can be used with aggregate personality trait levels to predict behaviour and understand the operation of culture.

[source] Interpersonal leveling, independence, and self-enhancement: a comparison between Denmark and the US, and a relational practice framework for cultural psychology,EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 3 2007Lotte Thomsen We argue that the relational model that people use for organizing specific social interactions in any culture determines whether people self-enhance. Self-enhancement is not a functional consequence of the (independent or interdependent) cultural model of self. Across three studies, Danes self-enhanced considerably less than did Americans but were more independent on the Twenty Statements Test, made more individual attributions about social life, made more autonomous scenario choices, and were more independent on the self-construal scale. Public modesty did not account for these Danish-American differences in self-enhancement. However, Danes practiced interpersonal leveling, preferring equality of outcome more than did Americans. This leveling strongly and inversely predicted self-enhancement within both cultures and mediated Danish-American differences in self-enhancement. In contrast, no independence measure systematically predicted self-enhancement within both cultures nor mediated the cultural differences in self-enhancement. This dissociation of independence and self-enhancement demonstrates that self-enhancing downward social comparisons are not functionally necessary for an independent concept of self. We conclude that social relationships, not the model of the self, mediate the mutual constitution of psyche and culture. Copyright © 2006 John Wiley & Sons, Ltd. [source] Escherichia coli thioredoxin inhibition by cadmiumFEBS JOURNAL, Issue 7 2004Asp2, Two mutually exclusive binding sites involving Cys3 Observations of thioredoxin inhibition by cadmium and of a positive role for thioredoxin in protection from Cd2+ led us to investigate the thioredoxin,cadmium interaction properties. We used calorimetric and spectroscopic methods at different pH values to explore the relative contribution of putative binding residues (Cys32, Cys35, Trp28, Trp31 and Asp26) within or near the active site. At pH 8 or 7.5 two binding sites were identified by isothermal titration calorimetry with affinity constants of 10 × 106 m,1 and 1 × 106 m,1. For both sites, a proton was released upon Cd2+ binding. One mole of Cd2+ per mole of reduced thioredoxin was measured by mass spectrometry at these pH values, demonstrating that the two binding sites were partially occupied and mutually exclusive. Cd2+ binding at either site totally inhibited the thiol,disulfide transferase activity of Trx. The absence of Cd2+ interaction detected for oxidized or alkylated Trx and the inhibition of the enzymatic activity of thioredoxin by Cd2+ supported the role of Cys32 at the first site. The fluorescence profile of Cd2+ -bound thioredoxin differed, however, from that of oxidized thioredoxin, indicating that Cd2+ was not coordinated with Cys32 and Cys35. From FTIR spectroscopy, we inferred that the second site might involve Asp26, a buried residue that deprotonates at a rather high and unusual pKa for a carboxylate (7.5/9.2). The pKa of the two residues Cys32 and Asp26 have been shown to be interdependent [Chivers, T. P. (1997) Biochemistry36, 14985,14991]. A mechanism is proposed in which Cd2+ binding at the solvent-accessible thiolate group of Cys32 induces a decrease of the pKa of Asp26 and its deprotonation. Conversely, interaction between the carboxylate group of Asp26 and Cd2+ at a second binding site induces Cys32 deprotonation and thioredoxin inhibition, so that Cd2+ inhibits thioredoxin activity not only by binding at the Cys32 but also by interacting with Asp26. [source] The N -acetylglutamate synthase/N -acetylglutamate kinase metabolon of Saccharomyces cerevisiae allows co-ordinated feedback regulation of the first two steps in arginine biosynthesisFEBS JOURNAL, Issue 5 2003Katia Pauwels In Saccharomyces cerevisiae, which uses the nonlinear pathway of arginine biosynthesis, the first two enzymes, N -acetylglutamate synthase (NAGS) and N -acetylglutamate kinase (NAGK), are controlled by feedback inhibition. We have previously shown that NAGS and NAGK associate in a complex, essential to synthase activity and protein level [Abadjieva, A., Pauwels, K., Hilven, P. & Crabeel, M. (2001) J. Biol. Chem.276, 42869,42880]. The NAGKs of ascomycetes possess, in addition to the catalytic domain that is shared by all other NAGKs and whose structure has been determined, a C-terminal domain of unknown function and structure. Exploring the role of these two domains in the synthase/kinase interaction, we demonstrate that the ascomycete-specific domain is required to maintain synthase activity and protein level. Previous results had suggested a participation of the third enzyme of the pathway, N -acetylglutamylphosphate reductase, in the metabolon. Here, genetic analyses conducted in yeast at physiological level, or in a heterologous background, clearly demonstrate that the reductase is dispensable for synthase activity and protein level. Most importantly, we show that the arginine feedback regulation of the NAGS and NAGK enzymes is mutually interdependent. First, the kinase becomes less sensitive to arginine feedback inhibition in the absence of the synthase. Second, and as in Neurospora crassa, in a yeast kinase mutant resistant to arginine feedback inhibition, the synthase becomes feedback resistant concomitantly. We conclude that the NAGS/NAGK metabolon promotes the co-ordination of the catalytic activities and feedback regulation of the first two, flux controlling, enzymes of the arginine pathway. [source] Interactions between Swi1-Swi3, Mrc1 and S phase kinase, Hsk1 may regulate cellular responses to stalled replication forks in fission yeastGENES TO CELLS, Issue 6 2009Michie Shimmoto The Swi1-Swi3 replication fork protection complex and Mrc1 protein are required for stabilization of stalled replication forks in fission yeast. Hsk1 kinase also plays roles in checkpoint responses elicited by arrested replication forks. We show that both Swi1 and Swi3, the abundance of which are interdependent, are required for chromatin association of Mrc1. Co-immunoprecipitation experiments show the interactions of Swi1-Swi3, Mrc1 and Hsk1. Mrc1 interacts with Swi3 and Hsk1 proteins through its central segment (378,879) containing a SQ/TQ cluster, and this segment is sufficient for checkpoint reaction. The SQ/TQ cluster segment (536,673) is essential but not sufficient for the interactions and for resistance to replication inhibitor hydroxyurea. Mrc1 protein level is increased in hsk1,89 cells due to apparent stabilization, and we have identified a potential phosphodegron sequence. These results suggest that interactions of the Swi1-Swi3 complex and Hsk1 kinase with Mrc1 may play a role in cellular responses to stalled replication forks in fission yeast. [source] Trajectories of Multiculturalism in Germany, the Netherlands and Canada: In Search of Common PatternsGOVERNMENT AND OPPOSITION, Issue 2 2010Elke Winter In the mid-1990s, Canadian scholarship introduced an important distinction between historically incorporated national minorities and ethnic groups emerging from recent immigration. While the former may be accommodated through federal or multinational arrangements, multiculturalism has come to describe a normative framework of immigrant integration. The distinction between these analytically different types of movements is crucial for Taylor's and Kymlicka's influential theories, but the relations between different types of national and ethnic struggles for rights and recognition have remained unexplored in much of the subsequent scholarly literature. This article starts from a theoretical position where different types of diversity are viewed as highly interdependent in practice. Tracing the trajectories of multiculturalism in three different countries, the article aims to identify common patterns of how changing relations between traditionally incorporated groups affect public perceptions of and state responses to more recent immigration-induced diversity. More specifically, it asks the following question: to what extent does the absence (in Germany), discontinuation (in the Netherlands) and exacerbation (in Canada) of claims on ethnocultural grounds by traditionally incorporated groups influence the willingness of the national majority/ies to grant multicultural rights to immigrants? [source] The effect of culture and self-construals on predispositions toward verbal communicationHUMAN COMMUNICATION RESEARCH, Issue 3 2001M-SKKS Aune This study tested the effects of culture and self-construals (i.e., independence and interdependence) on predispositions toward verbal communication. For the purpose of this study, we focused on two main areas of verbal communication predispositions: (a) communication apprehension and (b) argumentativeness. In our path model, we expected that culture-level individualism increases one's construal of self as independent, which, in turn, leads to a higher degree of argumentativeness and a lower level of communication apprehension. We also expected that culture-level individualism decreases one's construal of self as interdependent, which, in turn, leads to a lower degree of argumentativeness and a higher level of communication apprehension. Data to test the model were drawn from undergraduates (N=539) studying in Korea, Hawaii, and mainland U.S. The data were partially consistent with the theoretical predictions made. The implications of the results for theory and practice are discussed. [source] Older Married Workers and Nonstandard Jobs: The Effects of Health and Health InsuranceINDUSTRIAL RELATIONS, Issue 3 2009JEFFREY B. WENGER We examine the effects of health and health insurance coverage on older married workers' decisions to work in temporary, contract, part-time, self-employment, and regular full-time jobs. We model the behavior of older married workers as interdependent, showing that one spouse's health and insurance status affects the employment of the other. In general, we find that men and women are less likely to be employed in regular full-time jobs when they are in fair or poor health and are more likely to be in regular full-time employment when their spouses are in poor health.

Alec Chrystal Abstract This paper reports estimates of an econometric model of the determinants of OFCs' broad money holding and M4 lending to OFCs. This is of interest both as providing information about a component of UK money and credit aggregates and because it provides some evidence of the link between financial activity and growth of the real economy. We model the long-run equilibria for money holding and lending to this sector as being driven by GDP, wealth, the return to financial services and various interest spreads. The dynamics of OFCs' money and lending are shown to be interdependent. We then consider the evidence for interactions between OFCs and other sectors. Our results indicate that M4 lending to OFCs is significantly related to aggregate investment in the long run, but is largely unrelated to the spending of households.

[source] "Spontaneous" Interethnic Order: The Emergence of Collective, Path-Dependent CooperationINTERNATIONAL STUDIES QUARTERLY, Issue 4 2000Badredine Arfi Can "spontaneous," decentralized interethnic cooperation emerge among ethnic groups whose members heavily discount future interethnic relations and do not fear punishment for interethnic noncooperation? Why is it that once the interaction between two ethnic groups evolves along a certain (cooperative or conflictual) path it sometimes becomes harder for the interacting groups to reverse course and seek alternative paths? The answer to these two questions lies in the fact that individual members not only are always calculative and could hence act opportunistically, but also are interdependent and can learn from one another. Because the members of interacting groups operate interdependently they thereby create collective nonlinear path dependence. Using a social game (within evolutionary game theory) the article shows counterintuitively that the emergence of collective, nonlinear path dependence within and across ethnic groups whose members heavily discount the future and face no punishment for interethnic noncooperation makes "spontaneous" decentralized interethnic cooperation a long-run equilibrium. Collective cooperation can thus develop path-dependently among ethnic groups without a Damocles' sword of any sort hanging over their members' heads, even when most individuals are shortsighted and opportunistic. [source] Incident Command Skills in the Management of an Oil Industry Drilling Incident: a Case StudyJOURNAL OF CONTINGENCIES AND CRISIS MANAGEMENT, Issue 3 2005M.T. Crichton The successful management of a complex, hazardous event in many domains demands a high level of incident command skills. In the oil and gas exploration and production industry, these skills were required by members of an Incident Management Team (IMT) established to respond the failure of a drilling riser in the Gulf of Mexico. When an incident occurs, members of an industrial IMT form an interdisciplinary, interdependent, but ad-hoc team. As actual experience of dealing with major incidents of this nature is relatively rare, IMT members have to rely on emergency exercises in training, along with existing domain-specific knowledge. Following a serious incident on an offshore drilling rig, semi-structured interviews with the on-shore strategic and tactical level IMT members (n=7) were conducted. These interviews have resulted in the identification and definition of incident command skills for members of an industrial IMT, namely decision making, situation awareness, communication, leadership, and teamwork, all of which can be affected by stress, as well as organisational factors that influenced the outcome of the incident. Limitations in current incident management training were identified, namely the need for specific incident command skills training. A framework is suggested around which specific incident command skills training can be structured. Key learnings from this case study are also presented which can provide guidance for the training and preparation of industrial incident management teams. [source] Inter-organizational Collaboration and the Dynamics of Institutional FieldsJOURNAL OF MANAGEMENT STUDIES, Issue 1 2000Nelson Phillips While many aspects of the collaborative process have been discussed in the management literature, the connection between collaboration and the dynamics of institutional fields has remained largely unconsidered. Yet, collaboration is an important arena for inter,organizational interaction and, therefore, a potentially important context for the process of structuration upon which institutional fields depend. In this paper, we argue that institutionalization and collaboration are interdependent; institutional fields provide the rules and resources upon which collaboration is constructed, while collaboration provides a context for the ongoing processes of structuration that sustain the institutional fields of the participants. [source] Association of Caspr/paranodin with tumour suppressor schwannomin/merlin and ,1 integrin in the central nervous systemJOURNAL OF NEUROCHEMISTRY, Issue 2 2003Natalia Denisenko-Nehrbass Abstract Caspr/paranodin is an essential neuronal component of paranodal axoglial junctions, associated with contactin/F3. Its short intracellular domain contains a conserved motif (GNP motif) capable of binding protein 4.1 domains [FERM domains (four point one, ezrin, radixin, moesin)]. Schwannomin/merlin is a tumour suppressor expressed in many cell types, including in neurons, the function and partners of which are still poorly characterized. We show that the FERM domain of schwannomin binds to the paranodin GNP motif in glutathione S-transferase (GST)-pull down assays and in transfected COS-7 cells. The two proteins co-immunoprecipitated in brain extracts. In addition, paranodin and schwannomin were associated with integrin ,1 in transfected cells and in brain homogenates. The presence of paranodin increased the association between integrin ,1 and schwannomin or its N-terminal domain, suggesting that the interactions between these proteins are interdependent. In jimpy mutant mice, which display a severe dysmyelination with deficient paranodal junctions, the interactions between paranodin, schwannomin and integrin ,1 were profoundly altered. Our results show that schwannomin and integrin ,1 can be associated with paranodin in the central nervous system. Since integrin ,1 and schwannomin do not appear to be enriched in paranodes they may be quantitatively minor partners of paranodin in these regions and/or be associated with paranodin at other locations. [source] Personality and Close Relationships: Embedding People in Important Social ContextsJOURNAL OF PERSONALITY, Issue 6 2002M. Lynne Cooper ABSTRACT This special issue of the Journal of Personality is predicated on the assumption that close relationships provide the central stage for the drama of human experience. This all-important context both shapes and conditions the expression of personality, and thus must play an integral role in any truly adequate account of human behavior. The importance of this agenda is perhaps overshadowed only by its difficulty. Contributions to the present issue, therefore, take stock of past research, highlight current state-of-the-art research, and offer a vision of the next generation of research on personality and close relationships. The conceptual and methodological approaches highlighted in this issue remain faithful to the dynamic, interdependent, and multilayered nature of the processes linking personality and close relationships. [source] Religious Ethics, History, and the Rise of Modern Moral Philosophy: Focus IntroductionJOURNAL OF RELIGIOUS ETHICS, Issue 2 2000Jennifer A. Herdt In this introduction to a cluster of three articles on eighteenth-century ethics written by Mark Larrimore, John Bowlin, and Mark Cladis, the author maintains that although the broad narrative tracing the emergence of a religiously neutral or naturalistic moral language in the eighteenth century is a familiar one, many central questions concerning this development remain unanswered and require further historical study. Against those who contend that historical study is antecedent to, but not part of, the proper substance of religious ethics, the author argues that historical and normative studies are interdependent, each helping to define the questions central to the other. The introduction concludes with an overview of the three articles and suggests ways in which religious ethicists can, in the future, make a distinctive contribution to the history of ethics. [source] Stereotypical Relations and Utterance Understanding: An Introduction to Xu Sheng-Huan's Stereotypical Relation-Based Approach to PragmaticsLINGUISTICS & LANGUAGE COMPASS (ELECTRONIC), Issue 1 2010Wu Bing-zhang An utterance hardly provides adequate information for its understanding, but the stereotypical relations (SRs) suggested by its linguistic components and mode of expression help to complement the explicitly expressed content, thus making the utterance serve its communicative function. Stereotypical relations are a speaker/hearer's perception and memory of the relations between things in the experiential world. Such relations, once entrenched, are the cognitive device by which humans understand, represent, and express the world. Things in SRs are interdependent; the presence of one entails that of another. Therefore, an utterance implicates the necessary information by SRs to ,fill up' the information gap in the context of communication. Stereotypical relations can be characterized in terms of similarity and proximity, both of which are categories of degree. [source] International rivers and national security: The Euphrates, Ganges,Brahmaputra, Indus, Tigris, and Yarmouk rivers1NATURAL RESOURCES FORUM, Issue 4 2008Neda A. Zawahri Abstract To understand a state's incentives to invest in conflict or cooperation over their international rivers, this paper argues that it is necessary to appreciate the relationships a river can create and the national security threat riparians may confront. Rivers impose interdependent and vulnerable relationships, which can compromise a state's ability to respond effectively to floods and droughts, meet its domestic food and energy needs, dredge the river, maintain its drainage systems, and allocate its domestic water budget. The inability to accomplish these tasks can contribute to social, economic, and political losses that may threaten a state's territorial integrity. Regardless of whether a state is upstream or downstream, from these relationships it acquires leverage to manipulate the interdependence and vulnerability to inflict losses on its riparian neighbour. This argument challenges several assumptions within the existing literature, including the belief that a shortage of freshwater is the initial force producing a national security threat and that an upstream,downstream river bequeaths all advantages on the upstream state and leaves the downstream state purely dependent. As the paper shows, riparians confront a more complex relationship than captured by the existing literature. [source] Developmental cross talking in the ectomycorrhizal symbiosis: signals and communication genesNEW PHYTOLOGIST, Issue 1 2001Francis Martin Summary Development of ectomycorrhizas involves multiple genes that are implicated in a complex series of interdependent, sequential steps. Current research into ectomycorrhiza development and functioning is aimed at understanding this plant,microbe interaction in a framework of the developmental and physiological processes that underlie colonization and morphogenesis. After a brief introduction to the ectomycorrhizal symbiosis, the present article highlights recent work on the early signal exchange taking place between symbionts, and sketches the way functional genomics is altering our thinking about changes in gene expression during the early steps of the ectomycorrhiza development. [source] How does the color influence figure and shape formation, grouping, numerousness and reading?OPHTHALMIC AND PHYSIOLOGICAL OPTICS, Issue 5 2010The role of chromatic wholeness, fragmentation Abstract In this work it is suggested that color induces phenomenal wholeness, part-whole organization and fragmentation. The phenomenal wholeness subsumes the set of its main attributes: homogeneity, continuity, univocality, belongingness, and oneness. If color induces wholeness, it can also induce fragmentation. Therefore, in order to understand the role played by color within the process of part-whole organization, color is used both as a wholeness and as a fragmentation tool, thus operating synergistically or antagonistically with other wholeness processes. Therefore, color is expected to influence figure-ground segregation, grouping, shape formation and other visual processes that are related to the phenomenal wholeness. The purpose of this study is to rate the influence of color in inducing whole and part-whole organization and, consequently, in determining the perception of figure-ground segregation, grouping, shape formation, numerousness evaluation and time reading. We manipulated experimental conditions by using equiluminant colors to favor or break (parcel-out) the wholeness of objects like geometrical composite figures and words. The results demonstrated that color is aimed, among other psychological and biological purposes, at: (1) relating each chromatic component of an object, thus favoring the emergence of the whole object; (2) eliciting a part-whole organization, whose components are interdependent; (3) eliciting fragments and then breaking up the whole and favoring the emergence of single components. Wholeness, part-whole organization and fragmentation can be considered as three further purposes of color.

Finally, we allow for explicit collusion between administrators by introducing an administrator's agent who acts in the interests of all the administrators. The model shows that in equilibrium (fixed point) the degree of corruption, the degree of division of labour and productivity are interdependent. [source] | |||||||||||||||||||||||||
