Valuing Librarianship: Core Values in Theory and Practice

In 2004, the American Library Association (ALA)’s Core Values of Librarianship statement identified eleven core values: access; confidentiality and privacy; democracy; diversity; education and lifelong learning; intellectual freedom; preservation; the public good; professionalism; service; social responsibility. As the ALA document explains, “the foundation of modern librarianship rests on an essential set of core values that define, inform, and guide our professional practice. These values reflect the history and ongoing development of the profession and have been advanced, expanded, and refined by numerous policy statements of the American Library Association.” While the ALA is not the only national library association to articulate their core values, this issue is an explanation of how core values have shaped, influenced, and informed libraries and librarianship in North America and around the world. Individual values such as democracy, diversity, access, and social responsibility have been the subject of inquiry by prominent scholars in library studies. There has not, however, been a coherent collection of scholarship addressing these specific, individual values in the practice of librarianship. Valuing Librarianship, a special issue of Library Trends, is an attempt to redress this absence within the context of public, school, special, and academic libraries. This special issue of Library Trends features practicing librarians and LIS scholars addressing librarianship\u27s present and future in relation to its core values. Using the ALA Core Values of Librarianship statement as a framework, Valuing Librarianship explores how these core values have informed, influenced, guided, and contextualized libraries and librarianship in the past ten years and consider how these values might guide our profession in the future

By Librarians, For Librarians: Building a Strengths-Based Institute to Develop Librarians\u27 Research Culture in Canadian Academic Libraries

In spite of the increase in formal and informal expectations for research by Canadian librarians, there have been few—if any—Canada-wide initiatives to help support librarians in meeting research expectations. Moreover, there have been few opportunities to address academic librarians’ needs and Canadian librarian research culture in any systematic way, especially on a national scale. As a way of redressing these absences and filling this need, a four-day nation-wide institute was proposed and conducted in order to bring together Canadian librarians interested in developing their own research programs and working toward fostering a positive and productive research culture in Canadian academic libraries. This article describes the principles informing the institute’s development and locates the institute’s objectives within discussions of research culture, mentorship, and strengths-based approaches

Academic Librarians and Research: A Study of Canadian Library Administrator Perspectives

Within the literature exploring the role of research in academic librarianship, very little attention has been paid to the perspectives of upper libraryadministrators. This perspective is critical because library administrators play a key role in hiring, evaluating, supporting, promoting, and tenuring professional librarians. As a way of bringing the administrative perspective to these discussions, our study examines how library administrators within the Canadian Association of Research Libraries (CARL) view the role of research in their own libraries and within academic librarianship, as well as how they perceive the current and future climate for librarians’ research. Our study reveals key areas in need of further research and identifies several issues that librarians and upper administrators would benefit from exploring together to advance discussions about research

Evaluation of a dry EEG system for application of passive brain-computer interfaces in autonomous driving

© 2017 Zander, Andreessen, Berg, Bleuel, Pawlitzki, Zawallich, Krol and Gramann. We tested the applicability and signal quality of a 16 channel dry electroencephalography (EEG) system in a laboratory environment and in a car under controlled, realistic conditions. The aim of our investigation was an estimation how well a passive Brain-Computer Interface (pBCI) can work in an autonomous driving scenario. The evaluation considered speed and accuracy of self-applicability by an untrained person, quality of recorded EEG data, shifts of electrode positions on the head after driving-related movements, usability, and complexity of the system as such and wearing comfort over time. An experiment was conducted inside and outside of a stationary vehicle with running engine, air-conditioning, and muted radio. Signal quality was sufficient for standard EEG analysis in the time and frequency domain as well as for the use in pBCIs. While the influence of vehicle-induced interferences to data quality was insignificant, driving-related movements led to strong shifts in electrode positions. In general, the EEG system used allowed for a fast self-applicability of cap and electrodes. The assessed usability of the system was still acceptable while the wearing comfort decreased strongly over time due to friction and pressure to the head. Fromthese results we conclude that the evaluated system should provide the essential requirements for an application in an autonomous driving context. Nevertheless, further refinement is suggested to reduce shifts of the system due to body movements and increase the headset’s usability and wearing comfort

Connectivity-based parcellation of the thalamus explains specific cognitive and behavioural symptoms in patients with bilateral thalamic infarct

A novel approach based on diffusion tractography was used here to characterise the cortico-thalamic connectivity in two patients, both presenting with an isolated bilateral infarct in the thalamus, but exhibiting partially different cognitive and behavioural profiles. Both patients (G.P. and R.F.) had a pervasive deficit in episodic memory, but only one of them (R.F.) suffered also from a dysexecutive syndrome. Both patients had an MRI scan at 3T, including a T1-weighted volume. Their lesions were manually segmented. T1-volumes were normalised to standard space, and the same transformations were applied to the lesion masks. Nineteen healthy controls underwent a diffusion-tensor imaging (DTI) scan. Their DTI data were normalised to standard space and averaged. An atlas of Brodmann areas was used to parcellate the prefrontal cortex. Probabilistic tractography was used to assess the probability of connection between each voxel of the thalamus and a set of prefrontal areas. The resulting map of corticothalamic connections was superimposed onto the patients' lesion masks, to assess whether the location of the thalamic lesions in R.F. (but not in G. P.) implied connections with prefrontal areas involved in dysexecutive syndromes. In G.P., the lesion fell within areas of the thalamus poorly connected with prefrontal areas, showing only a modest probability of connection with the anterior cingulate cortex (ACC). Conversely, R.F.'s lesion fell within thalamic areas extensively connected with the ACC bilaterally, with the right dorsolateral prefrontal cortex, and with the left supplementary motor area. Despite a similar, bilateral involvement of the thalamus, the use of connectivity-based segmentation clarified that R.F.'s lesions only were located within nuclei highly connected with the prefrontal cortical areas, thus explaining the patient's frontal syndrome. This study confirms that DTI tractography is a useful tool to examine in vivo the effect of focal lesions on interconnectivity brain patterns

Discontinuation of a randomised controlled trial in general practice due to unsuccessful patient recruitment.

BACKGROUND: A randomised controlled trial (RCT) in general practice, recruiting incident patients with (sub)acute sciatica, was discontinued because of insufficient recruitment. AIM: To describe factors that influenced the recruitment process and ultimately led to discontinuation of this trial, and to enable others to learn from this experience. DESIGN & SETTING: A pragmatic RCT was designed to compare two pain medication prescription strategies for treatment of (sub)acute sciatica in general practice. After 1 year of patient recruitment, the trial was prematurely terminated. METHOD: To analyse the underperforming recruitment, patient information systems of 20 general practices were screened twice a month to search for eligible patients and identify reasons for non-eligibility. Secondly, after study termination, an open question was distributed to the participating GPs for their views on the recruitment process. RESULTS: A total of 116 GPs from 37 general practices collaborated in the trial. Only eight of 234 patients were included after 12 months. The 22 GPs who offered their opinion on the main reasons for unsuccessful recruitment considered that these were the low incidence rate and strict eligibility criteria, a strong patient and/or GP preference, and time constraints. CONCLUSION: For this RCT, multiple factors were related to recruitment problems but it remains unknown which determinants prevailed. As the research question is unanswered but remains relevant, it is recommended that GPs' daily practice is taken into account when designing an RCT, a pilot study should be performed for feasibility of recruitment, and GP assistants should be involved at an early stage

Stopping Antiepileptic Drugs: When and Why?

After a patient has initiated an antiepileptic drug (AED) and achieved a sustained period of seizure freedom, the bias towards continuing therapy indefinitely can be substantial. Studies show that the rate of seizure recurrence after AED withdrawal is about two to three times the rate in patients who continue AEDs, but there are many benefits to AED withdrawal that should be evaluated on an individualized basis. AED discontinuation may be considered in patients whose seizures have been completely controlled for a prolonged period, typically 1 to 2 years for children and 2 to 5 years for adults. For children, symptomatic epilepsy, adolescent onset, and a longer time to achieve seizure control are associated with a worse prognosis. In adults, factors such as a longer duration of epilepsy, an abnormal neurologic examination, an abnormal EEG, and certain epilepsy syndromes are known to increase the risk of recurrence. Even in patients with a favorable prognosis, however, the risk of relapse can be as high as 20% to 25%. Before withdrawing AEDs, patients should be counseled about their individual risk for relapse and the potential implications of a recurrent seizure, particularly for safety and driving
