AbstractPark and protected area agencies are increasingly enacting a “culture of collaboration” – or viewing relationships (with agencies, nonprofits, educational institutions, etc.) as the routine approach to meeting immediate needs and longer-term goals (e.g., relevance, stewardship). Trust is fundamental to developing a culture of collaboration. We examine potential components of trust in a culture of collaboration in National Park Service (NPS)-identified urban relationships promoting relevance with stakeholders. Specifically, we detail three-actor relationships and network-wide structures using a quantitative Exponential Random Graph Model analysis. Networks in Detroit, Tucson, and Boston exhibit potential transitions toward a culture of collaboration, perhaps spurred by the NPS’ Urban Agenda efforts. These relate to the development of trust, the NPS positionality as supportive rather than core in the networks, and the large potential for increasing reciprocity (which decreases network hierarchy). These structures highlight where Urban Agenda relationship-building processes may aid in developing collaborative cultures across settings. [ABSTRACT FROM AUTHOR]

Spinal muscular atrophy (SMA) is caused by a deficiency of the ubiquitously expressed survival motor neuron (SMN) protein. The main pathological hallmark of SMA is the degeneration of lower motor neurons (MNs) with subsequent denervation and atrophy of skeletal muscle. However, increasing evidence indicates that low SMN levels not only are detrimental to the central nervous system (CNS) but also directly affect other peripheral tissues and organs, including skeletal muscle. To better understand the potential primary impact of SMN deficiency in muscle, we explored the cellular, ultrastructural, and molecular basis of SMA myopathy in the SMNΔ7 mouse model of severe SMA at an early postnatal period (P0-7) prior to muscle denervation and MN loss (preneurodegenerative [PND] stage). This period contrasts with the neurodegenerative (ND) stage (P8-14), in which MN loss and muscle atrophy occur. At the PND stage, we found that SMN∆7 mice displayed early signs of motor dysfunction with overt myofiber alterations in the absence of atrophy. We provide essential new ultrastructural data on focal and segmental lesions in the myofibrillar contractile apparatus. These lesions were observed in association with specific myonuclear domains and included abnormal accumulations of actin-thin myofilaments, sarcomere disruption, and the formation of minisarcomeres. The sarcoplasmic reticulum and triads also exhibited ultrastructural alterations, suggesting decoupling during the excitation–contraction process. Finally, changes in intermyofibrillar mitochondrial organization and dynamics, indicative of mitochondrial biogenesis overactivation, were also found. Overall, our results demonstrated that SMN deficiency induces early and MN loss-independent alterations in myofibers that essentially contribute to SMA myopathy. This strongly supports the growing body of evidence indicating the existence of intrinsic alterations in the skeletal muscle in SMA and further reinforces the relevance of this peripheral tissue as a key therapeutic target for the disease.

This research explores focal actors and their dyads, addressing their sustainable collaboration in triads and its relevance in the agri-triads that share information along the supply chains. We employ a multiple-case approach and presents two triads through 42 interviews, observation and documentaries. An abductive approach, Transaction Cost Economics (TCE), conceptually guides the analytical iteration stages between theory and data. The findings describe the collaboration mechanisms of focal actors at triad levels and the development of their dyads capabilities for sustainable supply chains. Eight triad approaches emerge in the present research; these are grouped into three aggregated levels according to the intensity of information-sharing between focal and associate actors in each triad. The research has identified six contextual factors that are linked to the TCE dimensions of asset specificity, uncertainty and frequency, and offers key propositions. The research gained insights into how focal actors in dyadic triads choose between the available approaches based on different intensity levels of information-sharing. This research presents a conceptual framework informing the choice of triad approaches reflecting collaboration mechanism strategies, and thus the intensity of information-sharing and sustainability performance. The study elaborates on the application of TCE and extends it empirically to the literature. [ABSTRACT FROM AUTHOR]

Although negative ties may cause stress and harm well-being, they are also considered fundamental in close and ongoing relationships. This study distinguishes positive, negative, and – when characterized by both valences – ambivalent ties. Analyzing almost 10,000 personal networks from the Swiss CH-X study shows that: (1) ambivalence among family members is more prevalent than among non-family members, (2) ambivalent family dyads or triads are not negatively associated with well-being, and (3) certain balanced family triads are associated with higher well-being and an unbalanced non-family triad is associated with lower well-being. These results suggest that conflicts are not necessarily detrimental to young adults' well-being. • Ambivalence among family members is more prevalent than among non-family members. • Ambivalent family dyads or triads are not associated with lower well-being.

In spectral wave models, the nonlinear triad source term accounts for the transfer of energy to the bound higher harmonics. This paper presents an extension to commonly used spectral models that resolves the evolution of the bound wave energy by keeping track of the energy that has been bound by the triad interactions. This extension is referred to as the bound wave evolution (BWE) model. From this, the spatial evolution of the bound wave height is obtained, which serves as a proxy for the nonlinear wave shape. The accuracy of these bound wave heights, and thus wave shape predictions, is highly dependent on the accuracy of the triad source term. Therefore, in this study, the capability of the LTA and SPB triad formulations to capture the growth of the bound wave height is evaluated. For both of these formulations, it is found that slope dependent calibration parameters are required. Overall, despite being computationally more expensive, the SPB method proves to be significantly more accurate in predicting the bound wave evolution. In the shoaling zone, where the bound wave energy is dominated by triads, the BWE model is well capable of predicting the nonlinear wave's shape. In the surf zone, however, where a combination of triads and wave breaking control the spectral evolution, the BWE model over-predicts the bound wave height. Nevertheless, this paper shows the promising capabilities of spectral models to predict the nonlinear wave shape. [ABSTRACT FROM AUTHOR]

Abstract Partner choice promotes competition among individuals to be selected as a cooperative partner, a phenomenon referred to as competitive altruism. We explored whether chimpanzees engage in competitive altruism in a triadic Ultimatum Game where two proposers can send offers simultaneously or consecutively to a responder who can only accept one of the two competing offers. In a dyadic control condition only one proposer at a time could send an offer to the responder. Chimpanzees increased their offers across trials in the competitive triadic, but not in the dyadic control condition. Chimpanzees also increased their offers after being rejected in previous triadic trials. Furthermore, we found that chimpanzees, under specific conditions, outcompete first proposers in triadic consecutive trials before the responder could choose which offer to accept by offering more than what is expected if they acted randomly or simply offered the smallest possible amount. These results suggest that competitive altruism in chimpanzees did not emerge just as a by-product of them trying to increase over previous losses. Chimpanzees might consider how others’ interactions affect their outcomes and engage in strategies to maximize their chances of being selected as cooperative partners.

Hydrogen is troublesome in any periodic table classification. This being so it may as well be placed in a position that confers desirable attributes to the arrangement of the elements, while notionally recognising its lineage to the group 1 alkali metals and the group 17 halogens. Since the noble gases bridge the halogens and the alkali metals, and hydrogen encompasses the transition from the alkali metals to the halogens, there is more to the idea of hydrogen over helium. Hydrogen...seems to claim an exceptional position (Meyer 1870, p. 357) The real voyage of discovery consists not in seeking new lands but in seeing with new eyes (Proust 1927, p. 559) [ABSTRACT FROM AUTHOR]

Many studies on buyer–supplier-supplier triads demonstrate the value of the interactions between three business actors instead of two for identifying triadic collaboration strategies that can lead firms to improve their performance. However, there is little research to date that has explored which specific lean improvements the various types of buyer–supplier-supplier triads lead to. This paper fills this gap. We study an automotive supplier manufacturing company (the buyer) and its seven types of buyer–supplier-supplier triads emerging from the buyers' attempt to implement zero-defect manufacturing (ZDM) in the production process of a crash management system. The case study shows how a buyer manages their first-tier suppliers through three types of closed buyer–supplier-supplier triads, where all three actors collaborate to work for the common goal of ZDM. The case also shows four additional types of open triads, where the buyer relies on the first-tier supplier to manage the second-tier supplier without directly interacting with the latter. The paper discusses what types of triads in the case study seem to be associated with the buyers' efforts to achieve the following lean sub-goals of ZDM: full automation, production line flexibility, product flexibility, low cost, low defect rate, short cycle time, and minimum quality control. Finally, we also analyze the role of geographic proximity between the actors in open and closed buyer–supplier-supplier ZDM triads. [ABSTRACT FROM AUTHOR]

Paid employment in the criminal economy is, in many ways, the essence of precarious labour yet to date criminological work on the so-called 'gig economy' is scarce. Here we apply emergent sociological literature on 'post-Fordist' working cultures to precarious youth employment in Hong Kong, arguing: (1) recent reorganizations of labour markets towards flexible entrepreneurship are mirrored in the illicit economy; (2) a shift in structural features of triad gangs has led to a parallel form of 'network sociality'; and (3) triad-affiliated youth remained rooted in place-based 'communities of practice' that form a point of difference from existing theory. In concluding, we reflect on the implications of these arguments for the study of illicit economies, triads and post-Fordist working cultures. [ABSTRACT FROM AUTHOR]

The mafias, opening up from their territories of origin, have opened up to profound global transformations, also rethinking their own hierarchies of values, their own purposes and their own rules. In particular, in this paper the author deals with the Chinese mafia and its presence on Italian and European territory. In a transnational dimension, the Chinese underworld operates, with the native and foreign criminal cliques present in the territories, in carrying out illicit business and does this with a "mafia-style" methodology. Triad is the name given in the West to a secret society, founded in China in the 17th century and which has today become a dangerous mafia criminal organisation. It has its bases in Hong Kong and the island of Taiwan, but today it is increasingly widespread not only in the United States of America, but also in Italy and Europe [ABSTRACT FROM AUTHOR]

Rapport plays a key role in small group interaction, yet there remain gaps in understanding the construct. The current study examined whether initial group rapport among triads of strangers could predict later social bonding and group emotion. Results indicated that initial group rapport reliably predicted subsequent social bonding and emotional experience across multiple measures. These findings support use of global thin slice rapport measures in small groups. Further, they suggest that rapport can be assessed reliably within the first minute of meeting and that ratings of group experience in just this first minute offer valuable insight into subsequent group formation.

The social nature of customer experiences creates complex and potentially detrimental dynamics in failure situations, such as when other customers side with the complainer or the firm. The present research is the first to analyze such coalitions and their consequences. We conceptualize a triad composed of a complainer, a service employee, and one or multiple others as a third actor. A field study of consumer complaints on social media shows that coalitions occur in 32% of cases, negatively shifting the affective tone of an online conversation from approximately neutral to negative. Both third actor–complainer and third actor–service employee coalitions independently deteriorate the affective tone, their individual effects are not additive, and the third actor–complainer coalition exerts the larger impact of both coalitions. Two experiments reveal that complainers feel betrayed by the third actor when this actor sides with the service employee (vs. the complainer), which strengthens complainers' satisfaction with taking steps as a recovery effort by the firm and weakens satisfaction with an offered apology. This research provides managerial insights into the practical significance of coalition effects, how coalitions impair firm response effectiveness, and under which conditions different responses sustain their effectiveness. It also presents several avenues for future research. Graphical Abstract [ABSTRACT FROM AUTHOR]

The outcome-oriented e-education concept is one of the current international advanced education concepts, and its generation and development fit with the development of information technology and the social demand for the quality of talent cultivation. In this paper, a knowledge mapping system for university English courses based on the concept of outcome-orientated education is investigated to enable the integration of university English course knowledge and its visualization in the form of web pages. Knowledge points, concepts, definitions, and other information about the university English subject are extracted, and various data sources, which contain structured, semi-structured, and unstructured data, are collected, integrated, and extracted in the form of English knowledge triads. The system testing results indicate that, in comparison to the traditional DistMult method, this paper’s method enhances the classification accuracy of the three English course datasets by 0.93%, 1.68%, and 0.85%, respectively. The experimental results validate the effectiveness and superiority of the system. Meanwhile, the questionnaire survey found that the system can effectively help learners improve their confidence, interest, and initiative in learning, enhance their learning effectiveness, improve their learning efficiency, and provide them with high-quality learning resources that have good application value.

Android is now one of the most popular operating systems in the world because of its open source character, so the threshold for hackers to make malware has also become lower, and more and more malware has started to threaten people's lives. Graphs are used to represent the program's syntactic and semantic structure, and can naturally represent malicious behavior, so we propose a malware detection method named SFCGDroid, which based on sensitive function call graph, so we propose a malware detection method named SFCGDroid, which based on sensitive function call graph. We first decompile the Android application to generate a function call graph (FCG), and extract the sensitive function call graph (SFCG) on the FCG. Secondly, we extract two class features (1) use the Skip-gram model to obtain function embeddings, and (2) treat the SFCG as a social network and extract the triads attribute of the sensitive API. The two types of features are combined as a feature representation of the SFCG and fed into a graph convolutional network (GCN) for malware detection. For experiments on 26,939 Android software datasets, SFCGDroid in this paper can achieve 98.22% accuracy and 98.20% F1 score. [ABSTRACT FROM AUTHOR]

Phenomenology is the unity of principles and methods employed for investigating the essence of things. The present paper is a brief review of the series of publications that these authors carried out over the past decade. The general thrust of these publications consists in the idea that phenomenological ideas of physics are used to analyze earthquakes. One conspicuous example of a phenomenological theory is thermodynamics. Maxwell's electrodynamics is also a perfect example of a phenomenological theory. The phenomenology of earthquakes is still far from reaching that high level of excellence. A look at the rational knowledge of geodynamics shows that we have so far reached a preliminary stage where we are aware of the subject-matter, methods, and problems faced by the future phenomenological theory of earthquakes. Nevertheless, we already clearly see that our approach to the construction of such a theory has promise. We are using concrete examples to show that phenomenological concepts of general physics are helpful in the search for the principles of the theory, in the processing and analysis of concrete manifestations of seismicity.

This article leverages the theme of friendship in Oliver O'Donovan's Entering into Rest as a locus of comparison between his earlier Resurrection and Moral Order and the Ethics as Theology trilogy. It does so by using demonstrable methodological differences between the two moral-theological projects to illumine a fundamental theological coherence. The article pursues this task in five sections. The first expounds O'Donovan's reflection on friendship in Entering into Rest. The second articulates the triadic approach adopted in these reflections. The third examines a similar triad articulated by O'Donovan in Resurrection and Moral Order. The fourth uses this triadic connection to demonstrate theological coherence between Resurrection and Moral Order and the Ethics as Theology trilogy. The fifth concludes by raising a critical query about the arbitrariness of the triadic methodology employed by O'Donovan. The article's conclusion considers more generally—in light of O'Donovan's pursuit of ethics as theology—the inherent contingency and incompleteness of theological ethics. [ABSTRACT FROM AUTHOR]

Humans subtly synchronize body movement during face-to-face conversation. In this context, bodily synchrony has been linked to affiliation and social bonding, task success and comprehension, and potential conflict. Almost all studies of conversational synchrony involve dyads, and relatively less is known about the structure of synchrony in groups larger than two. We conducted an optic flow analysis of body movement in triads engaged in face-to-face conversation, and explored a common measure of synchrony: time-aligned bodily covariation. We correlated this measure of synchrony with a diverse set of covariates related to the outcome of interactions. Triads showed higher maximum cross-correlation relative to a surrogate baseline, and 'meta-synchrony', in that composite dyads in a triad tended to show correlated structure. A windowed analysis also revealed that synchrony varies widely across an interaction. As in prior studies, average synchrony was low but statistically reliable in just a few minutes of interaction. In an exploratory analysis, we investigated the potential function of body synchrony by predicting it from various covariates, such as linguistic style matching, liking, laughter and cooperative play in a behavioural economic game. Exploratory results do not reveal a clear function for synchrony, though colaughter within triads was associated with greater body synchrony, and is consistent with an earlier analysis showing a positive connection between colaughter and cooperation. We end by discussing the importance of expanding and codifying analyses of synchrony and assessing its function.

We consider the prehistorical development that at the time of the great Greek thinkers preceded the present definition of “science”. The present well-known paradoxes of theoretical physics (relativity and quantum mechanics) can be overcome if one assumes that “absolute” reality is represented by a “timeless” world, while “time” and “antitime” are occasional additional features that characterize “world” and “antiworld”. “World” and “antiworld” are, respectively, the realm of “matter” and “antimatter” etc. A set of five previous papers deals with the devoted full discussion of the improved axiomatic formulation of theoretical physics. The present paper illustrates a prehistorical background of the crucial concept of “time”, in the Western, Eastern (Hindu), and Far Eastern worlds. The main pertinent focus is on a prehistorical strong debate, which preceded the classic Greek world at the time when unknown and astute thinkers debated and wrote the Bible and the ancient books of Hinduism. The impressive result is that the concept of a timeless world was a concern that survived at least until the III century AD. Conversely, the present generally agreed feeling about “absolute” time finally prevailed - and became accepted like an unconscious and innate concept. The ancient “timeless” concept later survived in some ascetic thinkers, theologians, and in some popular beliefs – that were originally proposed as a simple way to explain some subtle concepts to the man-of-the-street. The whole discussion has some profound implication on the same meaning of “science”, including crucial ethical constraints. For comparison purpose, also the Far East concept of “time” is considered according to Confucianism, Taoism, and Buddhism. [ABSTRACT FROM AUTHOR]

Family systems theory suggests that the family is an organized system in which different subsystems influence each other within and across levels, such as across dyadic and higher-order family-level systems. It is therefore expected that dyadic mother – child and father – child relationships contribute to shape relational processes that take place at the triadic mother – father – child level. Consequently, this study examined whether the quality of mother – child and father – child interactions in toddlerhood was associated with subsequent quality of the coparenting relationship during mother – father – child triadic interactions in kindergarten. When children were aged 18 months, mother – child and father – child interactions were assessed observationally with 136 families. Four and a half years later, the quality of the coparenting relationship was assessed during triadic interactions. Analyses revealed that fathers (but not mothers) who had higher-quality dyadic interactions with their toddler had better coparenting interactions with their spouse four and a half years later. This prediction held above child temperament and both parents' marital satisfaction. These results highlight that the quality of father – child relationships may be centrally involved in the development of the coparenting alliance across the preschool years. [ABSTRACT FROM AUTHOR]

The measurement of preferences can be based on historical observations of consumer behaviour or on data describing consumer intentions. In the latter case, the measure-ment of preferences is performed using methods which express consumer attitudes at the time of research. However, most of these methods are very laborious, especially when a large number of objects is tested. In such cases incomplete analyses may prove useful. An incomplete analysis involves the division of objects into subgroups, so that each pair of objects appears at exactly the same frequency and all objects are in each subgroup. The purpose of the work is to compare two incomplete methods for measuring the similarity of preferences, i.e. the triad method and the tetrad method. These methods can be used whenever similarities are measured on an ordinal scale. They have been com-pared in terms of their labour intensity and ability to map the known structure of ob-jects, even when all pairs of objects in subgroups cannot be presented equally frequent-ly.

Abstract Motifs represent local subgraphs that are overrepresented in networks. Several disciplines document multiple instances in which motifs appear in graphs and provide insight into the structure and processes of these networks. In the current paper, we focus on social networks and examine the prevalence of dyad, triad, and symmetric tetrad motifs among 24 networks that represent six types of social interactions: friendship, legislative co-sponsorship, Twitter messages, advice seeking, email communication, and terrorist collusion. Given that the correct control distribution for detecting motifs is a matter of continuous debate, we propose a novel approach that compares the local patterns of observed networks to random graphs simulated from exponential random graph models. Our proposed technique can produce conditional distributions that control for multiple, lower-level structural patterns simultaneously. We find evidence for five motifs using our approach, including the reciprocated dyad, three triads, and one symmetric tetrad. Results highlight the importance of mutuality, hierarchy, and clustering across multiple social interactions, and provide evidence of “structural signatures” within different genres of graph. Similarities also emerge between our findings and those in other disciplines, such as the preponderance of transitive triads.

The article begins with a response to a recent contribution by Jensen, in which he has criticized several aspects of the use of triads of elements, including Döbereiner's original introduction of the concept and the modern use of atomic number triads by some authors including myself. Such triads are groups of three elements, one of which has approximately the average atomic weight of the other two elements, as well as having intermediate chemical reactivity. I also examine Jensen's attempted reconstruction Mendeleev's use of triads in predicting the atomic weights of three hitherto unknown elements, that were subsequently named gallium, germanium and scandium. The present article then considers the use of atomic number triads, in conjunction with the phenomenon of first member anomaly, in order to offer support for Janet's left-step periodic table, in which helium is relocated into group 2 of the table. Such a table features triads in which the 2nd and third elements of each group, without fail, fall into periods of equal length, a feature that is absent in the conventional 18-column or the conventional 32-column table. The dual sense of the term element, which is the source of much discussion in the philosophy of chemistry, is alluded to in further support of such a relocation of helium that may at first appear to contradict chemical intuition.

Abstract The relationship between a firm and its supply chain has been well studied, however, the association between the position of firms in complex supply chain networks and their performance has not been adequately investigated. This is primarily due to insufficient availability of empirical data on large-scale networks. To addresses this gap in the literature, we investigate the relationship between embeddedness patterns of individual firms in a supply network and their performance using empirical data from the automotive industry. In this study, we devise three measures that characterize the embeddedness of individual firms in a supply network. These are namely: centrality, tier position, and triads. Our findings caution us that centrality impacts individual performance through a diminishing returns relationship. The second measure, tier position, allows us to investigate the concept of tiers in supply networks because we find that as networks emerge, the boundaries between tiers become unclear. Performance of suppliers degrade as they move away from the focal firm (i.e., Toyota). The final measure, triads, investigates the effect of buying and selling to firms that supply the same customer, portraying the level of competition and cooperation in a supplier’s network. We find that increased coopetition (i.e., cooperative competition) is a performance enhancer, however, excessive complexity resulting from being involved in both upstream and downstream coopetition results in diminishing performance. These original insights help understand the drivers of firm performance from a network perspective and provide a basis for further research.

Escalating non-communicable disease multimorbidity rates among older adults is an emerging public health concern in India, but the literature sparsely addresses the epidemiology of multimorbidity. We explore levels, patterns, combinations and predictors of multimorbidity among older adults using information on 59,764 individuals, aged 45 years and older, from the first wave of Longitudinal Ageing Study in India (LASI), 2017-2018. We computed multimorbidity score for sixteen non-communicable diseases to identify frequently occurring morbidity patterns (dyads and triads) and assess the relationship between multimorbidity and selected background characteristics. Near third of the older adult population is affected by multimorbidity, with hypertension, gastrointestinal disorders, musculoskeletal disorders, diabetes and skin diseases being the most common. Policymakers should seek strategies to increase early detection and prevention of chronic diseases, delay the age at onset of disease for those who are not affected and improve management for those affected with multiple disease conditions.

The reuniens nucleus (RE) is situated at the most ventral position of the midline thalamus. In rats and mice RE is distinguished by bidirectional connections with the hippocampus and medial prefrontal cortex (mPFC) and a role in memory and cognition. In primates, many foundational questions pertaining to RE remain unresolved. We addressed these issues by investigating the composition of the rhesus monkey RE in both sexes by labeling for GABA, a marker of inhibitory neurons, and for the calcium-binding proteins parvalbumin (PV), calbindin (CB), and calretinin (CR), which label thalamic excitatory neurons that project to cortex. As in rats and mice, the macaque RE was mostly populated by CB and CR neurons, characteristic of matrix-dominant nuclei, and had bidirectional connections with hippocampus and mPFC area 25 (A25). Unlike rodents, we found GABAergic neurons in the monkey RE and a sparser but consistent population of core-associated thalamocortical PV neurons. RE had stronger connections with the basal amygdalar complex than in rats or mice. Amygdalar terminations were enriched with mitochondria and frequently formed successive synapses with the same postsynaptic structures, suggesting an active and robust pathway to RE. Significantly, hippocampal pathways formed multisynaptic complexes that uniquely involved excitatory projection neurons and dendrites of local inhibitory neurons in RE, extending this synaptic principle beyond sensory to high-order thalamic nuclei. Convergent pathways from hippocampus, A25, and amygdala in RE position it to flexibly coordinate activity for memory, cognition, and emotional context, which are disrupted in several psychiatric and neurologic diseases in humans.

Introduction. Long before the creation of a national writing system, the Oirats (Kalmyks) had developed a unique oral poetic tradition. By the late 17th century, there appeared a large number of translated poetic works distinguished by genre and artistic diversity. Oirat scholars would insistently turn to the rich oral poetic heritage. And triads were one such most ancient type of aphoristic poetry, their genre characteristics still remaining a matter of debate: some classify them as riddles, others as proverbs — but it is universally accepted that triads hold a special place in the oral poetic tradition. Triads were used not only by medieval authors but have also been turned to by modern Kalmyk writers. Goals. The article introduces into scientific discourse a text of the Oirat version of The Story of Usun Debeskertu Khan which contains triads and quatrains; analyzes didactic contents of the literary triads and compares them to oral (folk) ones. Materials and Methods. The work primarily employs the comparative analysis method. Despite triads have been published in a number of folklore collections (along with proverbs and riddles), their contents have never been investigated in the context of written monuments. Results. The wide use of triads in ancient oral poetic traditions of Mongolic peoples is evidenced by works of researchers from Mongolia, Russia, and China. So, it has been revealed that triads are not identical to riddles, constituting a separate Mongolic poetic genre and having been explicitly used in didactic written monuments as a special form of homilies. Conclusions. The Story of Usun Debeskertu Khan is a didactic composition containing triads and quatrains, the latter — judging from their contents and functions attributed — being essentially edifying (moralistic), which thus makes it possible to finally distinguish them from riddles as such.

Characterizing judgments of similarity within a perceptual or semantic domain, and making inferences about the underlying structure of this domain from these judgments, has an increasingly important role in cognitive and systems neuroscience. We present a new framework for this purpose that makes limited assumptions about how perceptual distances are converted into similarity judgments. The approach starts from a dataset of empirical judgments of relative similarities: the fraction of times that a subject chooses one of two comparison stimuli to be more similar to a reference stimulus. These empirical judgments provide Bayesian estimates of underling choice probabilities. From these estimates, we derive indices that characterize the set of judgments in three ways: compatibility with a symmetric dis-similarity, compatibility with an ultrametric space, and compatibility with an additive tree. Each of the indices is derived from rank-order relationships among the choice probabilities that, as we show, are necessary and sufficient for local consistency with the three respective characteristics. We illustrate this approach with simulations and example psychophysical datasets of dis-similarity judgments in several visual domains and provide code that implements the analyses at https://github.com/jvlab/simrank.

This paper examines how organizations collaborate with multiple partners, such as when they develop innovative and complex product platforms like smartphones, servers, and MRI machines that rely on technologies developed by organizations in three or more sectors. Research on multipartner alliances often treats them as a collection of independent dyads, neglecting the possibility of third-party influence and interference in dyads that can inhibit innovation. Using a multiple-case, inductive study of six groups, each composed of three organizations engaged in technology and product development in the computer industry, I examine the collaborative forms and processes that organizations use to innovate with multiple partners in groups. Groups that used the collaborative forms of independent parallel dyads or single unified triads generated mistrust and conflict that stemmed from expectations about third-party participation and overlapping roles and thus had low innovation performance and weaker ties. Other groups avoided these problems by using a dynamic collaboration process that I call “group cycling,” in which managers viewed their triad as a small group, decomposed innovative activities into a series of interlinked dyads between different pairs of partners, and managed third-party interests across time. By temporarily restricting participation to pairs, managers chose which ideas, technologies, and resources to incorporate from third parties into single dyads and ensured that the outputs of multiple dyads were combined into a broader innovative whole.

Recent research has shown that action knowledgeinfluences categorical decisions (Borghi, Flumini, Natraj &Wheaton, 2012; Chao & Martin, 2000; Iachini, Borghi &Senese, 2008; Kalénine, Shapiro, Flumini, Borghi &Buxbaum, 2013). Shipp, Vallée-Tourangeau, and Anthony,(2014) showed that action influences categorisation in aforced-choice triad task when combined with taxonomicinformation and presented within a functional context. Thepresent experiment examined whether participants wouldbe more likely to match items in a triad task based onshared actions following priming with the functionalactions of the objects. Participants engaged in the triad taskused in Shipp et al. after a priming phase where they eitherinteracted with a series of objects for their functionalcapacity (Action Priming), grouped them into categories(Taxonomic Priming) or moved them from one table toanother (Movement Priming). Items within the triads werepresented as an image either on a white background(context-lean condition) or as a functional scene with theobject being used by an agent (context-rich condition).Consistent with Shipp et al. the results showed that actionwas primarily used to base choices on the triad task whenthe action choice also shared a taxonomic relation, and waspresented in context. Additionally, participants were morelikely to select the action related item when they had beenprimed with the functional action of the objects. The resultsare discussed in terms of the transfer effect from the objectinteraction task that facilitates how the objects aresimulated (Barsalou, 1999, 2003; Yeh & Barsalou, 2006).

The forced-choice triad task has become increasinglypopular in use over recent years. While it is seen as beinga categorisation task (Lin & Murphy, 2001) variation intask instructions often leads to different results. Shipp,Vallée-Tourangeau, and Anthony (2014) used the triadtask to show that when participants are asked to choosean option that ‘goes best with the target’, they are morelikely to select the choice that shares an action relationwhen it also shares taxonomic information. Howeverusing the instruction to select the item that “goes best” isvague and might encourage a strategy other than acategorical decision. The present experiment used thesame triads as in Shipp et al. to test whether participantswould match items based on shared actions or sharedtaxonomic relations when given specific categorisationinstructions. The task instructions were manipulated sothat participants either selected the item that “goes best”,“goes best to form a category” or is “most similar” to thetarget. The results found instances where the instructionsof “goes best to form a category” led to a higherprobability that participants would select the actionchoices over the instructions of “goes best”. Howeverwhen participants were encouraged to use similarityoverall action choices were lower. Therefore the triadtask does encourage a natural categorisation strategy anddifferences in task instructions across research are aresult of the stimuli used.

Junctin is a transmembrane protein of striated muscles, located at the junctional sarcoplasmic reticulum (SR). It is characterized by a luminal C-terminal tail, through which it functionally interacts with calsequestrin and the ryanodine receptor (RyR). Interaction with calsequestrin was ascribed to the presence of stretches of charged amino acids (aa). However, the regions able to bind calsequestrin have not been defined in detail. We report here that, in non-muscle cells, junctin and calsequestrin assemble in long linear regions within the endoplasmic reticulum, mirroring the formation of calsequestrin polymers. In differentiating myotubes, the two proteins colocalize at triads, where they assemble with other proteins of the junctional SR. By performing GST pull-down assays with distinct regions of the junctin tail, we identified two KEKE motifs that can bind calsequestrin. In addition, stretches of charged aa downstream these motifs were found to also bind calsequestrin and the RyR. Deletion of even one of these regions impaired the ability of junctin to localize at the junctional SR, suggesting that interaction with other proteins at this site represents a key element in junctin targeting.0 [ABSTRACT FROM AUTHOR]

Our study investigates how collaboration from a triadic perspective affects the development of operational capabilities through a practice-adoption process. This research conducted a multiple case study in three triads in Brazil. The results imply that inter-organizational collaboration plays a positive role by moderating the relationship between information technology practices and the development of customization, responsiveness, and cooperation capabilities. Moreover, sharing information emerges as a critical factor for these three capabilities when collaboration is present. In addition, collaboration enables the development of improvement-thinking, dyadic-diffused relationships between buyer-supplier or supplier-supplier in an open triad. In this triadic structure, the first-tier supplier plays a unique role in information sharing and capabilities development. On the other hand, to ensure the development of other capabilities, such as responsiveness, the buyer and second-tier supplier must expand their connection to form at least a transitional structure.
