Ecological dependencies make remote reef fish communities most vulnerable to coral loss

2021

Ecosystems face both local hazards, such as over-exploitation, and global hazards, such as climate change. Since the impact of local hazards attenuates with distance from humans, local extinction risk should decrease with remoteness, making faraway areas safe havens for biodiversity. However, isolation and reduced anthropogenic disturbance may increase ecological specialization in remote communities, and hence their vulnerability to secondary effects of diversity loss propagating through networks of interacting species. We show this to be true for reef fish communities across the globe. An increase in fish-coral dependency with the distance of coral reefs from human settlements, paired with…

Editorial : Networks Applied in Science Education Research

2020

Science education research is, in many ways, involved with exploring relational aspects of diverse elements that affect students’ learning outcomes; at one end, the elements may be concepts to be learned, and at the other end, the relations between students in different types of learning settings and environments and, ultimately, how such elements may interact [...]

Communication Practices and Social Tie Formation: A Case Study of Recreational Lifestyle Sports Cultures

2017

This case study examines contemporary recreational sports practitioners’ communication practices and social tie formation from the perspective of two lifestyle sports disciplines: climbing and trail running. Online survey results from 301 climbers and trail runners from Finland indicate that computer-mediated communication (CMC) has established its place in recreational lifestyle sports cultures; however, it has not done it at the expense of face-to-face (FtF) communication. Online interaction produces weak social ties with instrumental and informative value, but physical location is essential in establishing ties with emotional and appraisal value. This paper argues that it is the sports s…

Amigaskene, alakulttuuri tietokoneen puitteissa : kuvauksia alakulttuurin ja teknologioiden yhteenkietoutumisesta

2008

Tutkielman aiheena on tietokoneharrastajien alakulttuuri, jota kutsutaan Amigaskeneksi. Tutkielmassa tarkastellaan ensinnäkin niitä kulttuurin ja tietotekniikan puitteita, joiden viitekehyksessä tietokone harrastajat toimivat. Alakulttuurina Amigaskene sijoittuu yhtäältä sitä ympäröivien kulttuurien, kuten vallitsevan yhteiskunnan ja Amigaskeneä edeltävän skene-alakulttuurin, kehiin ja toisaalta Amigan mahdollistamaan tietotekniseen viitekehykseen. Lisäksi tutkielmassa tarkastellaan teknologiavälitteisen alakulttuurin puitteisiin rakentuneita kulttuurisia aineksia, joiden johdosta alakulttuuri erottuu kulttuuriksi. Tutkielmassa käytetään alakulttuurin määritelmää ja toimijaverkostoteoriaa a…

Guanxi and social capital: Networking among women managers in China and Finland

2014

Considering that women are still under-represented in management, researchers have claimed that networking is an important career management tool for women. This study aims to empirically explore how women managers benefit from social networks in the information technology (IT) field in China and Finland. Guanxi, an Eastern term for social networking, has seldom been studied in terms of gender and career, especially within cross-cultural research. Social capital is a Western term for social networks. Using questionnaires, in-depth interviews and interpretive analysis, we compare the composition and structure of social networks used by women managers within the information technology sector …

Potential for cascading impacts of environmental change and policy on indigenous culture.

2022

AbstractGlobal environmental and societal changes threaten the cultures of indigenous peoples and local communities (IPLC). Despite the importance of IPLC worldviews and knowledge to sustaining human well-being and biodiversity, risks to these cultural resources are commonly neglected in environmental governance, in part because impacts can be indirect and therefore difficult to evaluate. Here, we investigate the connectivity of values associated with the relationship Ngātiwai (a New Zealand Māori tribe) have with their environment. We show that mapping the architecture of values-environment relationships enables assessment of how deep into culture the impacts of environmental change or pol…

Social Network Banking : A Case Study of 100 Leading Global Banks

2018

Social media is widely recognized as a challenging new communication technology in both economic and social contexts. The present article explores how banks have exploited this technology in the range of consumer retail banking services offered by 100 leading global banks on the three major social networking sites (SNS): Facebook, Twitter, and YouTube. Viewing social network (SN) banking as a separate delivery channel and offering a working definition of SN banking, the article shows that banks have been more cautious than other businesses in using SNS. The available services are classified on nine main dimensions: marketing, financial education and advice, information support, customer sup…

The Spanning Tree based Approach for Solving the Shortest Path Problem in Social Graphs

2016

Nowadays there are many social media sites with a very large number of users. Users of social media sites and relationships between them can be modelled as a graph. Such graphs can be analysed using methods from social network analysis (SNA). Many measures used in SNA rely on computation of shortest paths between nodes of a graph. There are many shortest path algorithms, but the majority of them suits only for small graphs, or work only with road network graphs that are fundamentally different from social graphs. This paper describes an efficient shortest path searching algorithm suitable for large social graphs. The described algorithm extends the Atlas algorithm. The proposed algorithm so…
