A library for the fifteenth through the twenty-first centuries

The University of California, San Francisco (UCSF), began developing a program for a new library in 1977, started the design in 1985, began construction in 1988, and opened the library in September 1990. The primary objectives were to design and build a facility that would house print collections under optimal conditions, allow for ten years' growth, be flexible enough to permit future reconfiguration, support present and future technologies, and provide beautiful spaces in which to study. The planning process is summarized, planning concepts are outlined, and considerations for the electronic library are briefly reviewed.     

Sorting of textual data bases: A variety generation approach to distribution sorting

A method of sorting large textual data-bases by computer using external storage is proposed. The range of sort-keys in a sample of data to be sorted is divided into a fixed set of partitions, which should also give an adequate representation of new data from a similar source. The partitions are composed of ordered key ranges. An incoming data stream is distributed into a series of bins according to the partition in which the key lies, and the bins are then seperately sorted, using an internal sort, to give an ordered file. It is shown how the number of disc accesses needed depends on the manner in which the bins become filled, and thus on statistics of the data. Experiments using an INSPEC data-base give information on which estimates of the efficiency of the method can be based.     

The partnership between project management and organizational change: Integrating change management with change leadership

The nature of project management is change. Even though all knowledge areas in the Project Management Body of Knowledge (PMBOK) are rooted in controlling change, none of these areas specifically addresses the human elements of change. There is a significant distinction between directly controlling change relative to the nonhuman aspects of a project ( change control) and effecting change in the human dimensions of a project through leadership ( change leadership). This article characterizes the distinctive activities of change leadership and change control and their interrelationship throughout the project life cycle. Although distinct, change control and change leadership are interdependent and mutually supporting—both are needed to support project success.     

ADHD,parent perspectives and parent–teacher relationships: grounds for conflict

Educational policy and the school effectiveness movement often involve rhetoric about the benefit of parent involvement in schools, but high‐quality relationships between parents and teachers are not always straightforwardly achieved, and this may be particularly true in the case of parents of children presenting with academic problems and/or social, emotional and behavioural difficulties. A systematic review of qualitative research was conducted to explore the school‐related experiences of parents of pupils diagnosed with attention deficit hyperactivity disorder (ADHD). Six studies reported in seven papers met the inclusion criteria. High‐quality parent–teacher relationships were found to be the exception, with mothers feeling silenced and criticised. Findings show commonalities with wider research about parents, but identify additional grounds for conflict resulting from parental blame for pupils' disruptive behaviour, and the ambivalent nature of the concept of ADHD.     

Cell chip array for microfluidic proteomics enabling rapid in situ assessment of intracellular protein phosphorylation

We discuss the ability to perform fluorescent immunocytochemistry, following cell fixation, using a microfluidic array of primary, nonadherent, single CD34+ stem cells. The technique requires small cell samples and proceeds with no cell loss, making it well-suited to monitoring these rare patient-derived cells. The chip allows us to correlate live cell dynamics across arrays of individual cells with post-translational modifications of intracellular proteins, following their exposure to drug treatments. Results also show that due to the microfluidic environment, the time scale of cell fixation was significantly reduced compared to conventional methods, leading to greater confidence in the status of the protein modifications studied.
