Quantifying scholarly output via citation metrics is the time-honored method to gauge academic success. Altmetrics, or alternative citation metrics, provide researchers and scholars with new ways to track influence across evolving modes of scholarly communication. This article will give librarians an overview of new trends in measuring scholarly influence, introduce them to altmetrics tools, and encourage them to engage with researchers in discussion of these new metrics.

Comparisons are made of two techniques for the trace analysis of volatile organic compound (VOC) emissions from consumer products: direct on-line sampling and analysis and on-line solid sorbent collection followed by off-line analysis. Two types of direct analyses are examined. The first consists of direct injection of emissions from a sample loaded environmental chamber into a gas chromatograph equipped with a flame ionization detector (FID) for compound identification. Direct injection of headspace collected emissions into a gas chromatograph equipped with a mass selective detector is the second direct method scrutinized. The more traditional technique of solid sorbent collection of the volatile organic emissions followed by thermal desorption (TD)/gas chromatographic (GC)/mass spectrometric (MS) analysis is compared to both direct on-line methods.

Falling is a major problem for the elderly population and much research has been done to investigate the risk factors for and means of preventing falls. However, very little research has been carried out looking at if and how therapists teach elderly people how to rise after a fall. This postal survey was undertaken to investigate whether therapists do anything to try to prevent falls, assess elderly people for suitability and teach them how to rise after a fall. The results showed that almost all the respondents (127 of 137) identified falling as a problem that they had to deal with in their patients over 65 years. The main focus of occupational therapists was to prevent falls by making environmental changes (for example, removing hazards) whereas physiotherapists were involved in physical changes (for example, balance training). Over half the respondents had considered teaching people how to rise after a fall. A range of different methods was used, which broadly fell into physical and verbal instructions or referral to other health care professionals. The sources of knowledge for teaching how to rise after a fall came mainly from previous clinical experience. Falls are an acknowledged problem in the elderly population and among these hospital and community based therapists about half had considered teaching or had taught elderly people how to rise after a fall.
