Egocentric networks are dynamic. Prior research has typically measured change in broad network characteristics or simply in membership turnover but given relatively little attention to the history of alter-ego relationships. Using rich information about alters over three waves in the UCNets study, we develop a novel approach that delineates a “trajectory” over time for each of the alters in the network and then uses all these observed trajectories to identify types of ego networks. Results from Multilevel Latent Growth Models reveal six distinct trajectories for alters: continuously active, awakened, dormant, dropped, transitory, and new. The distribution of those six trajectories coalesces at the ego-level into three network types – anchored, shifting, and regenerative – each with unique dynamics and compositional features. To illustrate the contribution of this approach, we examine the associations between life events and the three types of network dynamics among UCNets' young adults. Findings reveal subtle patterns of change: some events shape networks by reinforcing their cores, while others expand or reconfigure networks’ near and distant peripheries.
以自我为中心的网络是动态的。先前的研究通常衡量的是广泛网络特征的变化或简单的成员流动率,但相对较少关注另一个自我关系的历史。利用UCNets研究中关于三波变化的丰富信息,我们开发了一种新颖的方法,该方法描述了网络中每个变化随时间的“轨迹”,然后使用所有这些观察到的轨迹来识别自我网络的类型。多层潜在增长模型的结果揭示了六种不同的变化轨迹:持续活跃、觉醒、休眠、下降、短暂和新的。这六种轨迹的分布在自我层面上聚合成三种网络类型——锚定、移动和再生——每一种都具有独特的动态和组成特征。为了说明这种方法的贡献,我们研究了UCNets年轻人的生活事件与三种类型的网络动态之间的关联。研究结果揭示了微妙的变化模式:一些事件通过加强其核心来塑造网络,而另一些事件则扩展或重新配置网络的远近外围。

Stable or dynamic? Explaining the development of Muslim and non-Muslim boys’ and girls’ friendship-making across adolescence 稳定的还是动态的?解释穆斯林和非穆斯林男孩和女孩在青春期交友的发展

Friendship segregation between Muslim and non-Muslim youth in Europe is well documented. However, previous network studies provide only snapshots, thus ignoring whether interreligious friendship-making changes throughout adolescence. A recent non-network study suggests increasing in-group friendships among Muslim girls and stability among Muslim boys, but it could not explain these differences and did not consider interdependence with non-Muslims’ friendship-making. To overcome these limitations, we study the trajectories of friendship-making among Muslim and non-Muslim boys and girls and assess the explanatory power of three key determinants of interreligious friendship-making dynamics: interreligious attitudes, religious norms that constrain out-group friendships, and reactions to friendship-making behavior of other groups. Addressing the methodological limitations of non-network research, we study friendship trajectories with stochastic actor-oriented models for network evolution applied to five waves of longitudinal friendship network data among 1122 Muslim and non-Muslim youth in German schools. We find that Muslim girls start out with at least as many interreligious friends as Muslim boys but that their tendency to have non-Muslim friends decreases substantially throughout adolescence. By contrast, the religious friendship-making of both Muslim boys and non-Muslims of either gender remains stable over time. We show that the increase in in-group friendships only applies to Muslim girls with high religiosity and that it is particularly strong for cross-gender friendships, suggesting that gendered religious norms can explain differences in the dynamics of Muslim boys’ and girls’ friendship-making. By contrast, interreligious attitudes and reactions to shifts in other groups’ friendship-making do not contribute to the observed friendship-making trajectories.
在欧洲,穆斯林和非穆斯林青年之间的友谊隔离是有据可查的。然而,先前的网络研究只提供了快照,从而忽略了宗教间的友谊是否会在整个青春期发生变化。最近的一项非网络研究表明,穆斯林女孩群体内友谊的增加和穆斯林男孩群体内友谊的稳定,但它无法解释这些差异,也没有考虑到非穆斯林交朋友之间的相互依赖。为了克服这些限制,我们研究了穆斯林和非穆斯林男孩和女孩之间建立友谊的轨迹,并评估了宗教间建立友谊动态的三个关键决定因素的解释力:宗教间态度,限制群体外友谊的宗教规范,以及对其他群体建立友谊行为的反应。针对非网络研究方法的局限性,我们采用随机因素导向的网络进化模型研究友谊轨迹,并将其应用于德国学校1122名穆斯林和非穆斯林青年的五波纵向友谊网络数据。我们发现,穆斯林女孩一开始与穆斯林男孩拥有至少一样多的跨宗教朋友,但在整个青春期,她们结交非穆斯林朋友的倾向大幅下降。相比之下,穆斯林男孩和非穆斯林男女之间的宗教友谊随着时间的推移保持稳定。我们表明,群体内友谊的增加只适用于具有高度宗教信仰的穆斯林女孩,而且对跨性别友谊尤其强烈,这表明性别宗教规范可以解释穆斯林男孩和女孩建立友谊的动态差异。相比之下,宗教间的态度和对其他群体建立友谊的转变的反应对观察到的建立友谊的轨迹没有贡献。

The present paper aims at unravelling the networking dynamics regarding the evolution of an innovation-niche, by looking at its network configuration over time. To this end, we investigate the actors’ role within the network as well as the network architecture. We employ the social network analysis (SNA) to four different but interrelated types of networks characterising the Italian biofuel industry. Each network was investigated in both its development and maturity phase. Our findings show that, over the niche evolution, actors established new relations, increasing networks’ density and making the networks more centralized. Furthermore, while two out of four networks confirmed their small world configuration over time, one (i.e. “communication” network) increased its small-world-ness, providing a larger number of information channels and more social reinforcement chances for niche actors to innovate. Overall, results suggest that policy makers should accompany and ease the innovation-niche evolution path by fostering the participation of the laggard behind and actors' clusterization, moderating any possible lock-in risk.
本文旨在通过观察其网络配置随时间的变化,揭示关于创新利基演变的网络动态。为此,我们研究了参与者在网络中的角色以及网络架构。我们采用社会网络分析(SNA)对四种不同但相互关联的网络类型表征意大利生物燃料行业。每个网络都在其发展和成熟阶段进行了研究。研究发现,在生态位演化过程中,行动者建立了新的关系,增加了网络的密度,使网络更加集中。此外,随着时间的推移,四个网络中有两个确认了它们的小世界结构,一个(即“通信”网络)增加了它的小世界性,为利基参与者提供了更多的信息渠道和更多的社会强化机会。总体而言,研究结果表明,政策制定者应通过促进落后者的参与和参与者的聚集来陪伴和缓解创新-生态位演进路径,减缓可能出现的锁定风险。

This article presents an analysis of the impact of the number of alters elicited in an ego network on the structural properties of those networks. There continues to be debate about the pros and cons of eliciting a fixed number of alters for each respondent versus allowing the respondent to list as many or few alters as they would like. This article explores a random assignment of respondents to three treatment groups – (1) a fixed number of alters set at 30, (2) a variable number of alters up to 45, and (3) a variable number of alters up to 45 with a 20 alter minimum. The results indicate that, from a non-structural perspective, all levels of emotional proximity, interaction contexts, genders, and ages are consistently sampled across the three treatment groups. At the structural level, the behavior of individual metrics is also largely similar. However, the most significant differences arise in the collective behavior of structural metrics—specifically, in their correlation structure, the amount of redundant information each variable provides, and the diversity and interpretability of the observed structural variability. When a data collection strategy constrains network size, it reduces the sparsity of the correlation matrix, effectively decreasing the number of independent global variables needed to describe network structure and making these global variables less interpretable. In other words, networks constructed with a survey that limits size tend to be more similar to each other, exhibiting less structural diversity and yielding differences that are harder to interpret. However, we discuss how these differences may simply be mathematical artifacts, without necessarily implying a clear advantage in choosing one treatment over another. Finally, we argue that the field needs a targeted study to answer whether the differing numbers of alters listed is a function of network size.
本文分析了在自我网络中引起的改变数量对这些网络结构特性的影响。对于为每个受访者提供固定数量的更改与允许受访者列出尽可能多或少的更改之间的利弊,仍然存在争论。本文探讨了将受访者随机分配到三个治疗组-(1)固定数量的更改设置为30,(2)可变数量的更改设置为45,以及(3)可变数量的更改设置为45,最小更改为20。结果表明,从非结构的角度来看,所有层次的情感接近、互动背景、性别和年龄在三个治疗组中都是一致的。在结构层面上,单个指标的行为也在很大程度上相似。然而,最显著的差异出现在结构指标的集体行为中——具体而言,在它们的相关结构、每个变量提供的冗余信息的数量以及观察到的结构变异性的多样性和可解释性方面。当数据收集策略限制网络大小时,它降低了相关矩阵的稀疏性,有效地减少了描述网络结构所需的独立全局变量的数量,并使这些全局变量的可解释性降低。换句话说,通过限制规模的调查构建的网络往往彼此更加相似,表现出较少的结构多样性,产生难以解释的差异。然而,我们讨论了这些差异如何可能仅仅是数学上的人为因素,而不一定意味着选择一种治疗比另一种治疗有明显的优势。最后,我们认为该领域需要有针对性的研究来回答所列出的不同数量的变化是否是网络大小的函数。

International sanctions have been an increasingly common tool for enforcing international norms of behavior, among other goals. There is continuing debate on what drives sanctioning behavior: while IR theories of sanctions have a long empirical history, more recent studies identify a need to extend these theories to better account for the endogenous nature of state sanction networks. Using a combination of network and IR-based insights, we aim to build a theory-driven, interpretable model of international sanctions that has high predictive utility. Using a separable version of dynamic network logistic regression, we test network theories of “Matthew effects”, reciprocity, and previous state-level sanctioning activity alongside traditional IR theories regarding the democratic peace, cultural or institutional similarity, power imbalance, and trade. Though we find that mechanisms from established IR theories largely hold with the inclusion of network endogeneity, endogenous network effects are more powerful than traditional IR concepts for predictive accuracy of the sanctioning network. We also find considerable differences for factors driving the imposition of sanctions (tie formation) versus persistence of sanction regimes (persistence), pointing to the importance of treating such effects separately.
国际制裁已成为执行国际行为准则的一种日益普遍的工具。关于是什么驱动制裁行为的争论仍在继续:虽然制裁的IR理论有很长的经验历史,但最近的研究表明,有必要扩展这些理论,以更好地解释国家制裁网络的内生性质。结合网络和基于ir的见解,我们旨在建立一个理论驱动的、可解释的、具有高预测效用的国际制裁模型。使用动态网络逻辑回归的可分离版本,我们测试了“马太效应”的网络理论、互惠和以前的国家级制裁活动,以及关于民主和平、文化或制度相似性、权力不平衡和贸易的传统IR理论。虽然我们发现既有IR理论的机制在包含网络内生性的情况下基本成立,但对于制裁网络的预测准确性,内生性网络效应比传统IR概念更强大。我们还发现,推动实施制裁的因素(关系形成)与制裁制度的持续(持续)之间存在相当大的差异,这表明分别对待这两种影响的重要性。

Robust network scale-up method estimators 鲁棒网络放大方法估计

The Network Scale-up Method (NSUM) is a relatively recent statistical approach for estimating the prevalence of unknown populations through indirect surveys utilizing information about the respondents’ social circles. The popularity of NSUM has increased in recent years due to its ability to uphold privacy and cost-effectiveness. However, the NSUM is not exempt from biases resulting from participants’ behavior. In addition, the simpler and most popular NSUM estimators are based on averages, making them sensitive to deviations in the samples, which may cause significant errors. This work aims to study how robust procedures can overcome misreporting, contamination, and deviation due to conditions such as barrier effects, prevalence, skewness, and tail length. Specifically, the central objective of the article is to analyze the statistical robustness of NSUM methods, studying whether these methods are affected by outliers or unusual data. We employ eight robust proposals for each of the two classical NSUM estimators. We analyze robust estimators through simulation experiments using synthetic random networks such as Erdős–Rényi, Scale Free, and Stochastic Block Model structures to model different degree distributions and community structures with different prevalence levels in contaminated and uncontaminated scenarios. We compare the results of the simulations with real data on COVID-19 indicators in the United Kingdom and voting intention in the Spanish General Elections of 2023. This article shows that the classical NSUM estimators perform poorly in contaminated scenarios, while most of the robust proposals are not considerably affected. However, the performance of some robust NSUM estimators decreases under barrier effects. In addition, we observe that distortions created by small prevalence play an important role in selecting the most suitable robust NSUM estimator. Particularly, the robustification of the Mean of Ratios (MoR) estimator based on the Myriad operator typically exhibits the best performance (for MoR methods) across the various social network structures for different prevalence levels, reducing the estimation error regarding the non-robust methods by up to three orders of magnitude in contaminated scenarios.
网络放大法(Network Scale-up Method, NSUM)是一种相对较新的统计方法,通过间接调查利用被调查者的社交圈信息来估计未知人群的患病率。近年来,由于其保护隐私和成本效益的能力,NSUM越来越受欢迎。然而,NSUM也不能避免参与者行为造成的偏差。此外,最简单和最流行的NSUM估计器是基于平均值的,这使得它们对样本中的偏差很敏感,这可能会导致显著的误差。这项工作旨在研究稳健的程序如何克服由于屏障效应、流行率、偏度和尾长等条件造成的误报、污染和偏差。具体来说,本文的中心目标是分析NSUM方法的统计稳健性,研究这些方法是否受到异常值或异常数据的影响。我们对两个经典的NSUM估计分别采用了8个稳健的建议。我们通过模拟实验分析了鲁棒性估计,使用合成随机网络如Erdős-Rényi、Scale Free和随机块模型结构来模拟污染和未污染情景中不同程度分布和不同患病率水平的社区结构。我们将模拟结果与英国COVID-19指标和西班牙2023年大选投票意向的真实数据进行了比较。本文表明,经典的NSUM估计器在污染情况下表现不佳,而大多数鲁棒性建议没有受到很大影响。然而,一些鲁棒NSUM估计器在屏障效应下性能下降。此外,我们观察到小流行率产生的扭曲在选择最合适的稳健NSUM估计器中起着重要作用。特别是,基于Myriad算子的比率均值(MoR)估计器的鲁棒性通常在不同流行水平的各种社会网络结构中表现出最佳性能(对于MoR方法),在污染场景中将非鲁棒方法的估计误差减少了多达三个数量级。

We employ eight robust proposals for each of the two classical NSUM estimators. We analyze robust estimators through simulation experiments using synthetic random networks such as Erdős–Rényi, Scale Free, and Stochastic Block Model structures to model different degree distributions and community structures with different prevalence levels in contaminated and uncontaminated scenarios. We compare the results of the simulations with real data on COVID-19 indicators in the United Kingdom and voting intention in the Spanish General Elections of 2023. This article shows that the classical NSUM estimators perform poorly in contaminated scenarios, while most of the robust proposals are not considerably affected. However, the performance of some robust NSUM estimators decreases under barrier effects. In addition, we observe that distortions created by small prevalence play an important role in selecting the most suitable robust NSUM estimator. Particularly, the robustification of the Mean of Ratios (<span><math><mi>MoR</mi></math></span>) estimator based on the Myriad operator typically exhibits the best performance (for MoR methods) across the various social network structures for different prevalence levels, reducing the estimation error regarding the non-robust methods by up to three orders of magnitude in contaminated scenarios.</div></div>","PeriodicalId":48353,"journal":{"name":"Social Networks","volume":"84 ","pages":"Pages 46-61"},"PeriodicalIF":2.4,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing research on attitudes towards inequality has predominantly focused on individual class or socioeconomic position, with little attention paid to the role of personal networks. The limited existing research has primarily focused on the influence of specific class ties, while overlooking a crucial dimension: network size. Moreover, the lack of quantitative data containing information about socioeconomic standing, network configuration and attitudes over time for a group of the same individuals has hindered the accurate testing of the influence of personal networks on attitudes towards inequality. To address these gaps, the main goal of this paper is to examine the extent to which changes in the size and heterogeneity of acquaintanceship networks affect attitudes towards inequality in Chile – a country with high levels of income and wealth inequality. We utilise quantitative data from two waves (2016–2018) of a representative panel survey for the urban Chilean population, provided by the Chilean Longitudinal Social Survey (ELSOC). Our cross-sectional analyses indicate that network heterogeneity and network size both enhance perceptions of income inequality and preferences for equality, while decreasing perceptions of meritocracy. In the fixed effects regression models, however, network size is more closely linked to an increased perception of inequality, while network heterogeneity is more strongly associated with greater preferences for equality. Moreover, increases in network size tend to reduce meritocratic perceptions. These findings suggest that network size and network heterogeneity are complementary network characteristics in explaining attitudes towards inequality.
对不平等态度的现有研究主要集中在个人阶级或社会经济地位上,很少关注个人网络的作用。有限的现有研究主要集中在特定阶级关系的影响上,而忽略了一个至关重要的维度:网络规模。此外,由于缺乏包含同一个人群体的社会经济地位、网络结构和态度随时间变化的信息的定量数据,妨碍了准确测试个人网络对对待不平等态度的影响。为了解决这些差距,本文的主要目标是研究在智利这个收入和财富不平等程度很高的国家,熟人网络的规模和异质性的变化在多大程度上影响了人们对不平等的态度。我们利用智利纵向社会调查(ELSOC)提供的智利城市人口代表性小组调查的两波(2016-2018)定量数据。我们的横断面分析表明,网络异质性和网络规模都增强了对收入不平等的认知和对平等的偏好,同时降低了对精英的认知。然而,在固定效应回归模型中,网络规模与增加的不平等感知更密切相关,而网络异质性与更大的平等偏好更密切相关。此外,网络规模的扩大往往会降低精英主义的观念。这些发现表明,网络规模和网络异质性在解释对不平等的态度方面是互补的网络特征。

The co-evolution of informal social status and gossip in workplace social networks 职场社交网络中非正式社会地位与八卦的共同演化

This study examines the co-evolution of informal social status and the three positions in a gossip triad – gossip senders, receivers, and objects – in the workplace. Two different social mechanisms are proposed to explain these interrelationships, suggesting relationships between gossip and informal social status in the opposite direction. First, the social bonding perspective suggests that gossip bonds between actors in a gossip triad shape their informal social status. Second, the social capital perspective indicates that employees’ informal social status leads to their position within gossip triads. The hypotheses are tested in a three-wave social network study among employees in a Dutch childcare organization. Results of stochastic actor-oriented models indicate a co-evolution between informal social status and the receiver’s role in a gossip triad, but not with the roles of sender and object. Contrary to what the social capital perspective predicts, employees’ informal social status negatively affects receiving gossip over time. In line with the social bonding perspective, receiving gossip positively affects informal social status over time. The co-evolution process suggests that over time, an equilibrium may emerge where an employee’s informal social status stabilizes at a point where enough gossip is received to sustain their social position. We conclude that the previously often neglected receivers of third-party information should be considered when examining the dynamics of workplace gossip.
本研究考察了非正式社会地位和职场八卦三位一体中的三个位置——八卦发送者、接受者和对象——的共同演变。研究人员提出了两种不同的社会机制来解释这些相互关系,表明八卦与非正式社会地位之间的关系是相反的。首先,社会联系观点表明,八卦三位一体中的演员之间的八卦联系塑造了他们的非正式社会地位。第二,社会资本视角表明,员工的非正式社会地位导致其在八卦黑社会中的地位。这些假设在荷兰一家托儿机构的员工中进行了三波社交网络研究。随机因素导向模型的结果表明,非正式社会地位与八卦三元组中的接受者角色之间存在共同演化,但与发送者和对象角色之间没有共同演化。与社会资本观点的预测相反,随着时间的推移,员工的非正式社会地位会对接受八卦产生负面影响。根据社会关系的观点,随着时间的推移,接受八卦对非正式的社会地位有积极的影响。共同进化过程表明,随着时间的推移,一种平衡可能会出现,员工的非正式社会地位稳定在一个点上,在这个点上,有足够的八卦来维持他们的社会地位。我们的结论是,在研究职场八卦的动态时,应该考虑到以前经常被忽视的第三方信息的接收者。
