Managing Discovery and Linking Services

There is a growing trend toward a consolidation of services for electronic resources management, A–Z journal listings, full text link resolving, and discovery services under a single service provider. In many cases, the adoption of a discovery service from a provider that is not the same as the libraries’ existing link resolver service means managing multiple knowledgebases. In this session, three librarians gave an overview of their experiences and strategies for maintaining separate link resolving and discovery services in lieu of adopting a full suite of services from a single service provider. Each speaker presented a case study on the advantages and challenges of managing their chosen discovery service: EBSCO Discovery Service, Ex Libris’ Primo and ProQuest’s Summon, in conjunction with the CUFTS/GODOT open source knowledgebase and link resolver service.     

我国大学排行研究与实践的进展及评析

Lifestyles of the Rich and Famous: Celebrity Media Diet and the Cultivation of Emerging Adults’ Materialism

The present study used cultivation theory to explore the relationships between celebrity media diet and materialism for a sample of 224 emerging adults. Results indicated main effects between both celebrity magazine consumption and celebrity TV news consumption on materialism. Total celebrity media diet was also significantly related to materialism. Findings suggest that a media diet high in celebrity culture and lifestyle has significant impact on emerging adults’ preoccupation with consumerism, particularly for women. This research contributes to a growing body of literature on the effects of a celebrity-saturated media environment and the cultivation of materialistic attitudes.

“But it doesn’t come naturally”: how effort expenditure shapes the benefit of growth mindset on women’s sense of intellectual belonging in computing

Research suggests growth mindset, or the belief that knowledge is acquired through effort, may enhance women’s sense of belonging in male-dominated disciplines, like computing. However, other research indicates women who spend a great deal of time and energy in technical fields experience a low sense of belonging. The current study assessed the benefits of a growth mindset on women’s (and men’s) sense of intellectual belonging in computing, accounting for the amount of time and effort dedicated to academics. We define “intellectual belonging” as the sense that one is believed to be a competent member of the community. Whereas a stronger growth mindset was associated with stronger intellectual belonging for men, a growth mindset only boosted women’s intellectual belonging when they did not work hard on academics. Our findings suggest, paradoxically, women may not benefit from a growth mindset in computing when they exert a lot of effort.
