Understanding and Predicting Delay in Reciprocal Relations

Reciprocity in directed networks points to user's willingness to return favors in building mutual interactions. High reciprocity has been widely observed in many directed social media networks such as following relations in Twitter and Tumblr. Therefore, reciprocal relations between users are often regarded as a basic mechanism to create stable social ties and play a crucial role in the formation and evolution of networks. Each reciprocity relation is formed by two parasocial links in a back-and-forth manner with a time delay. Hence, understanding the delay can help us gain better insights into the underlying mechanisms of network dynamics. Meanwhile, the accurate prediction of delay has practical implications in advancing a variety of real-world applications such as friend recommendation and marketing campaign. For example, by knowing when will users follow back, service providers can focus on the users with a potential long reciprocal delay for effective targeted marketing. This paper presents the initial investigation of the time delay in reciprocal relations. Our study is based on a large-scale directed network from Tumblr that consists of 62.8 million users and 3.1 billion user following relations with a timespan of multiple years (from 31 Oct 2007 to 24 Jul 2013). We reveal a number of interesting patterns about the delay that motivate the development of a principled learning model to predict the delay in reciprocal relations. Experimental results on the above mentioned dynamic networks corroborate the effectiveness of the proposed delay prediction model.Comment: 10 page

The early childhood generalized trust belief scale

The study was designed to develop and evaluate the Early Childhood Generalized Trust Belief Scale (ECGTBS) as a method of assessing 5-to-8-year-olds’ generalized trust. Two hundred and eleven (103 male and 108 female) children (mean age 6 years and 2 months at Time 1) completed the ECGTBS twice over a year. A subsample of participants completed the ECGTBS after two weeks to assess the scale’s test-retest reliability. Exploratory and confirmatory factor analyses confirmed that the ECGTBS assessed the expected three factors: reliability, emotional trust, and honesty with item-pairs loading most strongly on their corresponding factor. However, the ECGTBS demonstrated low to modest internal consistency and test-retest reliability which indicates a need for further development of this instrument. As evidence for the convergent validity of the ECGTBS, the reliability and emotional trust items were associated with the children’s trust in classmates at Time 2. Concurrent asymmetric quadratic relationships indicated the importance of midrange generalized trust. Specifically, children with very high generalized trust experienced greater loneliness and children with very low generalized trust had fewer friendships than children with midrange trust

The Theory of Relational Cohesion: Review of a Research Program

In this paper we analyze and review the theory of relational cohesion and attendant program of research. Since the early 1990s, the theory has evolved to answer a number of basic questions regarding cohesion and commitment in social exchange relations. Drawing from the sociology of emotion and modem theories of social identity, the theory asserts that joint activity in the form of frequent exchange unleashes positive emotions and perceptions of relational cohesion. In turn, relational cohesion is predicted to be the primary cause of commitment behavior in a range of situations. Here we outline the theory of relational cohesion, tracing its development through the present day, and summarize the corpus of empirical evidence for the theory’s claims. We conclude by looking ahead to future projects and discussing some of the more general issues informed by our work

Trust, membership in groups, and household welfare

This paper explores the relationship between group membership and trust. Specifically, the authors examine (1) the importance of trust in the decision to join groups, (2) the subsequent ability of groups to generate trust, and (3) the influence of group membership and trust on a measure of well-being, per capita household income. They use longitudinal data from KwaZulu-Natal Province, South Africa, allowing them to control for potential simultaneity and measurement-error problems in the estimation. They disaggregate groups into financial and nonfinancial and “trust in people” by type of agent or actor. They can thus examine whether different types of trust are important for participating in different types of groups and whether different types of group participation are important for generating different types of trust. The research finds that (1) trust in local agents is an important determinant of membership in financial groups but not for membership in nonfinancial groups, (2) membership in both types of groups generates trust in nonlocal agents but not local agents, and (3) membership in financial and nonfinancial groups leads to higher well-being. The first two results suggest that financial groups serve a role in expanding the radius of trust, while the first and third results suggest a role for trust in improving well-being.Community participation South Africa. ,Financial institutions South Africa. ,Trust. ,Group membership. ,

Entrepreneurial Collaboration: Terms of Endearment or Rules of Engagement?

Many potential entrepreneurs face the choice as to whether they should collaborate when setting up in business. Small business research has generated little in the way of information or advice on collaborative entrepreneurship. This paper goes some way towards addressing that lack. The paper reports the findings of a survey of 106 collaborative entrepreneurs and describes their assessments of the benefits and disadvantages of co-ownership and their evaluation of the factors making for its success. Experiences of unsuccessful collaboration are also recounted. The findings illustrate how those involved saw collaborative entrepreneurship in terms of economic, organisational and interpersonal relationships. Whilst the benefits of collaboration were primarily economic, the affective aspects of the close inter-personal relationship provided the 'glue'. The paper makes a contribution to the arguments for a more holistic approach in small business research in general, and the need to take account of the impact of the feelings and beliefs of owner-managers on the 'economic' choices they make.entrepreneurship, collaboration, small businesses, venture teams

An investigation of children's peer trust across culture: is the composition of peer trust universal?

The components of children's trust in same-gender peers (trust beliefs, ascribed trustworthiness, and dyadic reciprocal trust) were examined in samples of 8- to 11-year-olds from the UK, Italy, and Japan. Trust was assessed by children's ratings of the extent to which same-gender classmates kept promises and kept secrets. Social relations analyses confirmed that children from each country showed significant: (a) actor variance demonstrating reliable individual differences in trust beliefs, (b) partner variance demonstrating reliable individual differences in ascribed trustworthiness, and (c ) relationship variance demonstrating unique relationships between interaction partners. Cultural differences in trust beliefs and ascribed trustworthiness also emerged and these differences were attributed to the tendency for children from cultures that value societal goals to share personal information with the peer group

Beyond Personalization: Research Directions in Multistakeholder Recommendation

Recommender systems are personalized information access applications; they are ubiquitous in today's online environment, and effective at finding items that meet user needs and tastes. As the reach of recommender systems has extended, it has become apparent that the single-minded focus on the user common to academic research has obscured other important aspects of recommendation outcomes. Properties such as fairness, balance, profitability, and reciprocity are not captured by typical metrics for recommender system evaluation. The concept of multistakeholder recommendation has emerged as a unifying framework for describing and understanding recommendation settings where the end user is not the sole focus. This article describes the origins of multistakeholder recommendation, and the landscape of system designs. It provides illustrative examples of current research, as well as outlining open questions and research directions for the field.Comment: 64 page

IT governance in SMEs: trust or control?

It is believed by many scholars that a small and medium-sized enterprise (SME) cannot be seen through the lens of a large firm. Theories which explain IT governance in large organizations and methodologies used by practitioners can therefore not be extrapolated to SMEs, which have a completely different economic, cultural and managerial environment. SMEs suffer from resource poverty, have less IS experience and need more external support. SMEs largely contribute to the failure of many IS projects. We define an out-sourced information system failure (OISF) as a failure of IT governance in an SME environment and propose a structure for stating propositions derived from both agency theory and theory of trust. The theoretical question addressed in this paper is: how and why do OISFs occur in SMEs? We have chosen a qualitative and positivistic IS case study research strategy based on multiple cases. Eight cases of IS projects were selected. We found that trust is more important than control issues like output-based contracts and structured controls for eliminating opportunistic behaviour in SMEs. We conclude that the world of SMEs is significantly different from that of large companies. This necessitates extra care to be taken on the part of researchers and practitioners when designing artefacts for SMEs

Claiming spaces: Prioritising Maaori worldview

Ohomairangi Trust was established as a provider of early intervention services in February 2002. It is funded and accredited by the Ministry of Education, and is the first Kaupapa Maaori based early intervention service to be accredited by the Ministry of Education. Essentially Ohomairangi was developed because of a need in the community for a service that could focus on developing and providing early intervention in a uniquely Maaori way, without the constraints of a crown agency. The Ohomairangi early intervention team has a commitment to supporting both the positive developments for Maaori within the Ministry of Education, and the continued independent research and development of Kaupapa Maaori services. The primary purpose of Ohomairangi is to develop and provide a Kaupapa Maaori based early intervention service across Taamaki Makaurau, which meets recommended practice guidelines. This evolves from a starting point of Kaupapa Maaori theory
