Nowadays, new motivations and tourists demands together with the international economic situation, commit the territories to search for new tourism products to consolidate the destinations. Among these new proposals, cultural tourism emerges with strength and museums tourism is a good alternative. In this context, the main objective of this work is to analyze the existence of structural social capital generated around the museums located in the city of Bahia Blanca (province of Buenos Aires, Argentina). The study analyses the social networking site Facebook specially. Social capital’s influence in the number of visitors that museums annually receive is also analysed. The paper carries out a brief conceptualization of cultural tourism and museums as dynamic elements of the territories. The study of structural social capital is made using the technique of social networks analysis (ARS) with the NODEXL program that allows identifying the structural characteristics of actors’ networks. Findings allow checking the hypothesis that a higher structural social capital is directly related to the annual number of visitors the museums receive.
如今,新的动机和游客的需求,以及国际经济形势,促使各地区寻求新的旅游产品,以巩固目的地。其中,文化旅游强势崛起,博物馆旅游是一个不错的选择。在这种背景下,这项工作的主要目的是分析位于巴伊亚布兰卡市(阿根廷布宜诺斯艾利斯省)的博物馆周围产生的结构性社会资本的存在。该研究特别分析了社交网站Facebook。社会资本对博物馆每年接待的游客数量的影响也进行了分析。本文对文化旅游和博物馆作为领土的动态元素进行了简要的概念化。结构性社会资本的研究是使用社会网络分析(ARS)技术和NODEXL程序进行的,该程序允许识别行为者网络的结构特征。研究结果允许检验较高的结构性社会资本与博物馆每年接待的游客数量直接相关的假设。

This paper analyzes the socio-relational structure of the employees of the Secretariat for Personnel Management of the Federal District Court of Accounts (TCDF). The analysis of internal and external social relations allowed to map the network of relationships and identify the impact of relationships on actors’ performance. The research is characterized as qualitative and quantitative analysis and uses social networking associated with statistical analysis techniques. The results confirm the influence of interpersonal relations on the performance of employees. It is observed that social bonds formed between the employees of the body originate inside the institutional environment, which leads to a rapprochement between the formal hierarchy and structure and the social relationships established. These features allow the inference that trust development in the TCDF is associated to formal processes and the institutional structure.

La migracion es un fenomeno complejo que requiere del analisis exhaustivo mediante diferentes metodos que incluyan cuestiones demograficas y territoriales, y que ademas permitan obtener informacion relevante para establecer la conexion entre los migrantes y el territorio. El Analisis de Redes Sociales (SNA en Ingles) como herramienta de relacion entre entidades, personas o grupos, proporciona una vision poco estudiada sobre los campos y sitemas migratorios que comunmente se establecen con medidas de intensidad propias de la demografia (Courgeau, 1970). Asi estas medidas no consideran que los sistemas relacionales consideren espacios o territorios contiguos y no contiguos como parte de un fenomeno intenso y dinamico. El objetivo de este articulo es explorar el uso de la metodologia del SNA en la descripcion de los campos migratorios y centralidades usando datos del censo de Colombia sobre la migracion intermunicipal. Los resultados muestran como la determinacion de estos campos es posible pero a su vez muestra las diferencias que existen en el calculo dependiendo de los algoritmos usados.
移民是一个复杂的现象,需要通过不同的方法进行详尽的分析,包括人口和领土问题,并提供相关信息,以建立移民和领土之间的联系。社会网络分析(SNA)作为实体、个人或群体之间关系的工具,提供了一个很少研究的领域和移民系统的观点,通常建立在人口统计强度的测量(Courgeau, 1970)。因此,这些措施不认为关系系统将连续和不连续的空间或领土视为强烈和动态现象的一部分。本文的目的是探讨SNA方法在描述哥伦比亚城市间移民人口普查数据时的使用。结果表明,这些字段的确定是可能的,但同时也显示了计算中存在的差异,取决于所使用的算法。

El siguiente articulo busca caracterizar las familias chilenas a traves del analisis de redes. Para ello, se aplican tecnicas de analisis que combinan entrevistas cualitativas, analisis de redes ego-centradas y analisis narrativos de los individuos de tal forma de identificar las redes que se constituyen segun el genero y el parentesco que adoptan las familias, ampliando las concepciones tradicionales sobre la estructura familiar. A traves de los datos cualitativos, las cartas de parentesco realizadas y la conformacion de redes, se propone una estrategia de analisis a traves de tecnicas mixtas de investigacion. Los resultados indican que las familias pueden ser categorizadas y comprendidas utilizando este tipo de acercamiento. Mientras que las familias de Santiago pueden ser descritas en cuatro tipologias: redes de camarilla, de familia cohesionada, de familias con redes extendidas y/o ramificadas, y red familiar de centro-periferia.
本文试图通过网络分析来描述智利家庭的特征。本文采用定性访谈、自我中心网络分析和个人叙事分析相结合的分析技术,以识别根据性别和亲属关系构成的家庭网络,扩展了传统的家庭结构概念。通过定性数据、亲缘关系图和网络形成,提出了混合研究技术的分析策略。家庭研究结果表明,可以利用这种方法所涉及的分类和。圣地亚哥的家庭可以被描述为四种类型:小集团网络、有凝聚力的家庭、扩展和/或分支网络的家庭以及中心-外围家庭网络。

The theory of social networks has been widely documented in the context of international migration. Most of these investigations focus on the strength shown by the ties of kinship and friendship to attract migrants. However, few studies have investigated the processes of network configuration and its structural influence on migration empirically. The objective of this article is to use the methodology of Social Network Analysis, to identify structural properties that may be influencing the spread of the migratory phenomenon in Venezuela, and to describe the reticular structure of skilled migration and its evolution towards the configuration of a possible transnational community. To do this, we collected data from personal (egocentric) networks among a community of Venezuelan living in Paris. The results confirm that the personal networks of the interviewees have the power to spread the migratory behavior in Venezuela and they show evidence of the configuration of a transnational community of Venezuelans in Paris.
社会网络理论在国际移民的背景下得到了广泛的记录。这些调查大多集中在亲属关系和友谊所显示的吸引移民的力量上。然而,很少有研究对网络配置过程及其结构对迁移的影响进行实证研究。本文的目的是使用社会网络分析的方法,确定可能影响委内瑞拉移民现象传播的结构特性,并描述技术移民的网状结构及其向可能的跨国社区配置的演变。为此,我们从居住在巴黎的委内瑞拉社区的个人(以自我为中心)网络中收集了数据。研究结果证实,受访者的个人网络具有传播委内瑞拉移民行为的能力,并显示了巴黎委内瑞拉人跨国社区配置的证据。

Caminos trazados: redes de itinerarios de los turistas rusos en Andalucía 路线规划:俄罗斯游客在安达卢西亚的路线网络
Pub Date : 2018-01-12 DOI: 10.5565/REV/REDES.745

This article describes the movements between cities of Russian tourists in Andalusia. With the application of network analysis strategies, we examined 1,681 displacements between 80 cities by 354 Russian tourists in Andalusia. The itineraries were reconstructed from information provided by tourists in a survey conducted between one and three years after their trip. With the analysis of QAP correlations, we explored the relationship between the route network and the distance matrix between cities, the itineraries offered by agency catalogs, car travel networks and the public transport network between cities. We also evaluated homophilia according to the thematic orientation of the visit, comparing "sun and beach" destinations with monumental visits. The routes of Russian tourists in Andalusia seem more influenced by the airport of arrival and the thematic definition of the visit, than by the offer of the agencies or the attractions associated with each tourist destination. With regard to this general trend, the only two elements of differentiation were the occasional cultural visits by sun and beach tourists, or the rental of cars by a small percentage of travelers.
这篇文章描述了俄罗斯游客在安达卢西亚城市之间的流动。运用网络分析策略,我们调查了354名俄罗斯游客在安达卢西亚80个城市之间的1,681次迁移。这些行程是根据游客在旅行一到三年后进行的一项调查中提供的信息重建的。通过QAP相关性分析,探讨了城市间路线网络与城市间距离矩阵、旅行社目录提供的行程、汽车旅行网络和城市间公共交通网络之间的关系。我们还根据访问的主题方向评估了同性性,将“阳光和海滩”目的地与纪念性访问进行比较。俄罗斯游客在安达卢西亚的路线似乎更多地受到抵达机场和旅游主题定义的影响,而不是受到各旅游目的地相关机构或景点的影响。就这一总体趋势而言,唯一的两个差异因素是阳光和海滩游客偶尔的文化访问,或一小部分旅行者的租车。

The construction of an agenda for Climate Change Adaptation is a neither neutral nor intrinsically good, politically complex process. It builds a discoursive field were different social entities with particular interests and perspectives interact with each other while putting forward transformation paths with diverse social consequencies. Therefore, it is valid to ask, which are those paths, how are they developed, and to which political view are they aligned? For Venezuela, a country designated as Vulnerable by the UN (UNFCCC), what characterizes the techno-political discourse of the Venezuelan academic community that contributes to this Agenda, and how does it describe the Adaptation process? In the following work, these questions were answered by analyzing the structure of co-authorship and social capital networks associated with the authors and research groups identified in the literature. Moreoever, the scientific practices were described through the systematization of information related to their methodological approaches and scientific productivity, among others. There is a highly fragmented community framed in the narrative of risk management and reduction of climate change impacts, characteristic of the historical moment of construction of multilateral consensus and of the notion of anthropogenic climate change. Some of the ecological-political implications of the results obtained are discussed.
制定适应气候变化议程既不中立,本质上也不好,政治上也很复杂。它构建了一个具有特定利益和观点的不同社会实体相互作用的话语场域,同时提出了具有不同社会后果的转型路径。因此,我们有理由问,哪些是这些道路,它们是如何发展的,它们与哪种政治观点相一致?委内瑞拉是联合国气候变化框架公约(UNFCCC)指定的脆弱国家,委内瑞拉学术界为该议程做出贡献的技术政治话语有何特点?它如何描述适应进程?在接下来的工作中,通过分析与文献中确定的作者和研究小组相关的共同作者和社会资本网络的结构来回答这些问题。此外,科学实践是通过与方法方法和科学生产力等有关的信息的系统化来描述的。在风险管理和减少气候变化影响的叙述中,存在着一个高度分散的社区,这是构建多边共识和人为气候变化概念的历史时刻的特征。讨论了所得结果的一些生态-政治含义。
