Abstract
Purpose
In this conceptual essay, the purpose of this paper is to argue that the structure of databases and other information systems provides valuable information beyond their content. The author contends that reading databases – as a separate, distinct activity from retrieving and reading the documents that databases contain – is an under-studied form of human-information interaction. Because the act of reading databases encourages awareness, reflection, and control over information systems, the author aligns the author’s proposal with “slow” principles, as exemplified by the slow food movement.
Design/methodology/approach
This paper presents an extended argument to demonstrate the value of reading a database. Reading a database involves understanding the relationship between database structure and database content as an interpretation of the world. For example, when a supermarket puts vermicelli in the pasta section but rice vermicelli in the Asian section, the supermarket suggests that rice vermicelli is more “Asian” than “noodle.” To construct the author’s argument, the author uses examples that range from everyday, mundane activities with information systems (such as using maps and automated navigation systems) to scientific and technical work (systematic reviews of medical evidence).
Findings
The slow, interpretively focused information interactions of reading databases complement the “fast information” approach of outcome-oriented retrieval. To facilitate database reading activities, research should develop tools that focus user attention on the application of database structure to database contents. Another way of saying this is that research should exploit the interactive possibilities of metadata, either human-created or algorithmically generated.
Originality/value
This paper argues that information studies research focuses too heavily on seeking and retrieval. Seeking and retrieval are just two of the many interactions that constitute our everyday activities with information. Reading databases is an area particularly ripe with design possibilities.

Abstract
This paper looks at the first full year of the implementation of CISTI Source at the Queen Elizabeth II Library, Memorial University of Newfoundland. The paper comments generally on journal use by title and takes a close look at the level of ordering associated with a group of Elsevier journal titles cancelled in 2002. It looks at the difficulty of putting in place a mechanism to prevent the ordering of articles for which there are local holdings in both paper and/or electronic formats. It discusses the consequences of not having an adequate blocking mechanism in the context of the overall cost of CISTI Source versus savings garnered from journal cancellations. The paper looks at user uptake and reaction to the new document delivery service. The paper reports briefly on the trial delivery of colour articles by Ariel between CISTI and the Queen Elizabeth II Library.

Abstract
Purpose
This study aims to focus on verifying the possibility of monitoring the condition of a turboprop engine using data recorded by on-board avionics Garmin G1000. This approach has potential benefits for operators without the need to invest in specialised equipment. The main focus was on the inter-turbine temperature (ITT). An unexpected increase in temperature above the usual value may indicate an issue with the engine. The problem lies in the detection of small deviations when the absolute value of the ITT is affected by several external variables.
Design/methodology/approach
The ITT is monitored by engine sensors and stored by avionics 1× per second onto an SD card. This process generates large amount of data that needs to be processed. Therefore, an algorithm was created to detect the steady states of the engine parameters. The ITT value also depends on the flight parameters and surrounding environment. As a solution to these effects, the division of data into clusters that represent the usual flight profiles was tested. This ensures a comparison at comparable ambient pressures. The dominant environmental influence then remain at the ambient air temperature (OAT). Three OAT compensation methods were tested in this study. Compensation for the standard atmosphere, compensation for the standard temperature of the given flight level and compensation for the speed of the generator, where the regression analysis proved the dependence between the ambient temperature and the speed of the generator.
Findings
The influence of ambient temperature on the corrected ITT values is noticeable. The best method for correcting the OAT appears to be the use of compensation through the revolutions of the compressor turbine NG. The speed of the generator depends on several parameters, and can refine the corrected ITT value. During the long-term follow-up, the ITT differences (delta values) were within the expected range. The tested data did not include the behaviour of the engine with a malfunction or other damage that would clearly verify this approach. Therefore, the engine monitoring will continue.
Practical implications
This study presents a possible approach to turbine engine condition monitoring using limited on board avionic data. These findings can support the development of an engine condition monitoring system with automatic abnormality detection and low operating costs.
Originality/value
This article represent a practical description of problems in monitoring the condition of a turboprop engine in an aircraft with variable flight profiles. The authors are not aware of a similar method that uses monitoring of engine parameters at defined flight levels. Described findings should limit the influence of ambient air pressure on engine parameters.

Abstract
It has been suggested that children's repeated traumatisation, such as repeated exposure to physical or sexual abuse, evokes defensive operations and experiential distortions that lead to personality disorder. This understanding has major implications with regard to how staff understand their patients, their role within the relationship and the therapy approach they take. Analysis of staff's understandings regarding influences upon the therapeutic relationship with women diagnosed as borderline personality disorder, acknowledges the centrality of trauma/attachment difficulties; however, this continues to perceive relationships as internalised difficulties within the women. This research explores the negative compounding factors that result in re‐enactments of early attachments and the need for shared responsibility for producing such relationships, in order to develop a more therapeutic, supporting and validating experience for both patients and staff.

Abstract
Provides an example of a firm’s use of distinguishing product attributes to engineer and nurture strong consumer‐brand relationships. Ty Inc., manufacturer of the popular Beanie Babies brand, has effectively engineered the brand to incorporate attributes of nostalgic value, personification, uniqueness, facilitation, engagement, aesthetic appeal, quality/excellence, association, social visibility and image congruence, and price risk. By incorporating these attributes and actively nurturing consumer‐brand relationships, Ty has benefited from greater customer satisfaction, which has led to higher purchase volumes, brand loyalty, and positive word‐of‐mouth communications. The straightforward methodology used to examine customer perceptions of Beanie Babies involved asking respondents to rate Beanie Babies on the ten characteristics associated with high‐involvement, relationship‐prone products. The same measurement approach could be easily replicated by managers of other firms to evaluate the relational potency of their own brands.

Abstract
Purpose
The purpose of this study is to mirror the late guitarist Peter Green’s life experiences through insights from Andrew Voyce, who recovered from mental illness, and expertise from Peter Bryngelsson, a Swedish professional musician and author.
Design/methodology/approach
The authors used a mixed method of collaborative autoethnography, psychobiography and digital team ethnography.
Findings
Despite having not previously attracted academic interest, Peter Green’s experiences of mental health problems and his return to recording and performance provide a rich data source when mirrored and compared to the lives and experiences of Andrew Voyce and Peter Bryngelsson.
Research limitations/implications
The main limitation of this piece of work is that Peter Green died in 2020. During the process of writing, the authors have had to follow different, mostly unacademic, sources that have described various parts of Peter Green’s life. The authors have given examples and drawn conclusions from their own lives as well as from academic sources, which they have found appropriate.
Practical implications
Both Andrew Voyce and Peter Bryngelsson’s stories would be helpful when it comes to a deeper understanding as to why Peter Green “took a left turn”, i.e., turned his back on an accepted lifestyle.
Social implications
Acid casualty is a problem connected to both mental distress and to the music industry. Peter Bryngelsson’s story tells us that one can remain sane and drug free and still be an influential and creative musician.
Originality/value
The analysis has brought together two stories of mental distress in combination with insights.

This paper investigates the relationship between (1) business cycle and use of personal contacts to obtain job and (2) use of personal contacts to obtain job and wages.
Abstract
Purpose
This paper investigates the relationship between (1) business cycle and use of personal contacts to obtain job and (2) use of personal contacts to obtain job and wages.
Design/methodology/approach
For this, we use data from the Monthly Employment Survey (2002–2015) from Brazil which has detailed information on individual and job characteristics. In addition, we investigate the impact of referrals on wage using quantile regressions.
Findings
Time-varying parameter estimates indicate that the relationship between business cycle and use of personal contacts became less countercyclical over time. In general, they show that there is more evidence of a slow changing relationship between personal contacts and the business cycle over time rather than a sudden and discrete one. Using quantile regressions, we observed that, controlling for similar observable characteristics, and including unobserved heterogeneity, wage differences between workers using personal contacts versus workers using others channels disappear. The evidences indicate that workers resort to personal contacts because of valuation of non-pecuniary job characteristics.
Practical implications
The results suggest that, in designing subsidy or affirmative action programs, attention to network effects is important. Social networks can help labor markets run more smoothly by alleviating information frictions.
Originality/value
This study extends the existing literature by providing empirical evidence of the use of personal contacts for the Brazil. Although there are many studies and methods for measuring use of personal contacts, to our knowledge, there are no studies using a time-varying parameters model.

Abstract
This study examines how a social studies methods course, with an emphasis in civic education, is taught and carried through from its original implementation within a teacher education social studies course to practicing teachers’ classrooms. Findings suggest that by implementing social action curriculum projects teachers: 1) effectively integrated emerging curriculum, 2) facilitated student-led instruction in a democratic classroom, 3) increased effective communication and built partnerships beyond the classroom, and 4) used structured reflections as a tool for growth and evaluation.
