So what are you going to do with that?: The promises and pitfalls of massive data sets

ABSTRACT

This article takes as its case study the challenge of data sets for text mining, sources that offer tremendous promise for DH methodology but present specific challenges for humanities scholars. These text sets raise a range of issues: What skills do you train humanists to have? What is the library's role in enabling and supporting use of those materials? How do you allocate staff? Who oversees sustainability and data management? By addressing these questions through a specific use case scenario, this article shows how these questions are central to mapping out future directions for a range of library services.     

Who are the independent editors,how did they reach their role and what are their associated job satisfactions?

This paper presents new evidence on the world of the independent editor in the publishing industry, analysing their demographic background, education and training, working practices, links with professional organizations, motivations for ‘going it alone‘, and job satisfaction. The results help contribute to the understanding of this important and growing segment of the publishing industry, challenge some of the commonly held beliefs about their role in the industry and set these within the broader context of changes in work organization in publishing. Contrary to the assumption that self‐publishing largely takes place without the involvement of an editor, research into the processes of self‐publishing (previously published in this journal) found that editors (and other providers of publishing services) were in fact often involved. The results are significant for the traditional publishing industry, the users of independent editorial services, and the editors themselves.     

Searching ClinicalTrials.gov and the International Clinical Trials Registry Platform to inform systematic reviews: what are the optimal search approaches?

Background:

Since 2005, International Committee of Medical Journal Editors (ICMJE) member journals have required that clinical trials be registered in publicly available trials registers before they are considered for publication.

Objectives:

The research explores whether it is adequate, when searching to inform systematic reviews, to search for relevant clinical trials using only public trials registers and to identify the optimal search approaches in trials registers.

Methods:

A search was conducted in ClinicalTrials.gov and the International Clinical Trials Registry Platform (ICTRP) for research studies that had been included in eight systematic reviews. Four search approaches (highly sensitive, sensitive, precise, and highly precise) were performed using the basic and advanced interfaces in both resources.

Results:

On average, 84% of studies were not listed in either resource. The largest number of included studies was retrieved in ClinicalTrials.gov and ICTRP when a sensitive search approach was used in the basic interface. The use of the advanced interface maintained or improved sensitivity in 16 of 19 strategies for Clinicaltrials.gov and 8 of 18 for ICTRP. No single search approach was sensitive enough to identify all studies included in the 6 reviews.

Conclusions:

Trials registers cannot yet be relied upon as the sole means to locate trials for systematic reviews. Trials registers lag behind the major bibliographic databases in terms of their search interfaces.

Implications:

For systematic reviews, trials registers and major bibliographic databases should be searched. Trials registers should be searched using sensitive approaches, and both the registers consulted in this study should be searched.Clinical trials registers such as ClinicalTrials.gov and portals to trials registers such as the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) are increasingly used to identify ongoing or completed clinical trials. These resources offer important information on the methods and progress of trials likely to be of interest to a range of users, including researchers, clinicians, and patients. The extent to which these resources can be relied upon as a sole source of trials for inclusion in systematic reviews, including Cochrane systematic reviews (CSRs), is the subject of the research study reported here. This study also investigates the most efficient ways that librarians, information professionals, and other searchers can search these resources. Search efficiency was investigated by evaluating the overlap and unique yield of searches in the two resources and by testing four search approaches. The tested search approaches ranged from the very precise (single specific condition search term combined with a single specific intervention search term) to the very sensitive (at least two interventions terms).

Access to learning resources for students on placement in the UK: what are the issues and how can we resolve them?

AIM: To compile a list of the issues regarding access to learning resources which affect students on placement in the UK and suggest some ways in which these can be resolved. RESULTS: Issues relating to PC access, network access, software, firewalls, disciplinary procedures, electronic information resources, virtual learning environments, service level agreements, physical access to libraries, book loans, reading lists and course committees are identified and discussed in relation to NHS libraries. CONCLUSIONS: Successful resolution of the IT and library issues, which are increasingly inter-linked, can help to ensure that students have a positive placement experience. Resolution will depend on close, regular liaison and can be assisted by negotiation of a clear Service Level Agreement.     

What do academic libraries tweet about,and what makes a library tweet useful?

People spend an increasing amount of time using social media systems to network, share information, learn, or engage in leisure activities (e.g., gaming). Libraries too are establishing a social media presence to promote the library and provide services to user populations through the social media systems the users frequent. This study explores Twitter uses by six large academic libraries and factors that make library tweets useful. 752 tweets were analyzed by topic to develop a subject typology of library tweets. In addition, tweets and Twitter user characteristics were analyzed to explore what makes library tweets useful, as measured by the number of retweets and favorites received. Content analysis of the samples of library tweets revealed nine content types, with the event and resource categories being the most frequent. In addition, the analysis showed that tweets related to study support services and building and maintaining connections with the library community were the most frequently retweeted and selected as favorites. The presence of a URL in the tweet was positively associated with the number of retweets, and the number of users followed was positively associated with the number of favorites received. Finally, a negative correlation was found between the account age and number of favorites.     

Questions asked at the virtual and physical health sciences reference desk: how do they compare and what do they tell us?

The questions asked at the traditional reference desk are decreasing while questions asked at the virtual reference desk are on the rise. Over a one-month period, the types of reference questions asked at an academic health sciences library were coded. This paper examines and compares the types of questions asked at the current day reference desk versus the virtual reference desk. This paper also reviews past literature examining the types of questions asked via virtual reference and the traditional reference.     

So,are early career researchers the harbingers of change?

This article provides the final results of a 3‐year study that sought to discover whether early career researchers (ECRs) were the harbingers of change with respect to scholarly communications. Over a hundred science and social science ECRs from seven countries, spanning three continents, were depth‐interviewed annually for 3 years (2016–2018) about their attitudes and behaviours with respect to 23 scholarly issues and activities (aspects). In order to provide an accessible overarching assessment of an extremely large and complex dataset, the interview data were categorized according to the strength and direction of change exhibited and the trends and points of interest raised. Results show that all ECRs have changed in one way or another, and a small minority has changed greatly in both attitude and practice and that collaboration and research impact are the scholarly aspects where most changes have occurred, and the greatest cause of change is not so much new technology as a change of jobs.

Culture and evidence: or what good are the archives? Archives and archivists in twentieth century England

Archives have the potential to change people’s lives. They are created to enable the conduct of business and accountability, but they also support a democratic society’s expectations for transparency and the protection of rights, they underpin citizen’s rights and are the raw material of our history and memory. This paper examines these issues in the context of the historical development of archives and archivists in twentieth century England. The research lays the foundations for understanding how and why the modern archives and records management profession developed in England. This paper will investigate the historical conflict (or is it a continuum?) between archives as culture and as evidence. The story identifies and highlights the contributions made by many fascinating individuals who established archives services and professional practice in England in the twentieth century. They shaped the archive in a very real way, and their individual enthusiasms, interests and understandings set the course of the English archival profession. To a great extent, it was these individuals, rather than government or legislation, that set the boundaries of English archives, they decided what was included (acquired) and what was not (of archival value.) The conclusion will consider the more fundamental questions: what are archives and what are they for, or perhaps, ‘what good are the archives’?
